    1995-01-01

    International nuclear trade is governed by the regime of legal control of nuclear energy, nuclear materials, knowledge of nuclear processes and weapons. Nuclear trade is under pinned by international agreements concerning physical protection and safeguards, the control of nuclear weapons, the protection of nuclear materials from terrorist action and third part liability. The political and geographical boundary changes of the past two years have significantly altered the background against which this regime has developed. Such changes have affected nuclear trade. The paper summarised the legal control of nuclear energy between States, identifies the areas of change which may affect this regime and the consequences for international trade. Conclusions are drawn as to the development of the international legal control of nuclear energy. (author). 21 refs

    2013-01-01

    This paper presents a scenario of legal control of software in measuring instruments. Such control is hampered by intrinsic problems related to software analysis and verification. To circumvent these difficulties, several projects are being developed to attack different stages of legal control, such as the model type approval, periodic verifications and metrological expertise. The proposals that will arise from these projects will be discussed among the parts and may be incorporated into the measuring instruments. (author)

    Full Text Available Purpose: To analyze the types of medical malpractice, medical errors, and medical disputes in a university hospital for the proposal of countermeasures that maximize the efficiency of hospital management, medical departments, and healthcare providers. Materials and Methods: This study retrospectively reviewed and analyzed 55 closed civil lawsuits among 64 medical lawsuit cases carried out in Pusan National University Hospital from January 2000 to April 2013 using medical records, petitions, briefs, and data from the Medical Dispute Mediation Committee. Results: Of 55 civil lawsuits, men were the main plaintiffs in 31 cases (56.4%. The average period from medical malpractice to malpractice proceeding was 16.5 months (range, 1 month to 6.4 years, and the average period from malpractice proceeding to the disposition of a lawsuit was 21.7 months (range, 1 month to 4 years and 11 months. Conclusions: Hospitals can effectively manage their legal risks by implementing a systematic medical system, eliminating risk factors in administrative service, educating all hospital employees on preventative strategies, and improving customer service. Furthermore, efforts should be made to establish standard coping strategies to manage medical disputes and malpractice lawsuits, operate alternative dispute resolution methods including the Medical Dispute Mediation Committee, create a compliance support center, deploy a specialized workforce including improved legal services for employees, and specialize the management-level tasks of the hospital.

  5. Legal control of large technical projects

    Papier, H.J.

    1981-01-01

    More legal security, acceleration of court procedures, a fair consideration of the interests of the permission recipients, avoidance of any kind of political usurpation, as well as the attempts of judges not to present an amateuriser scientific-technical indepth-knowledge cannot be accomplished via Sporadic appeals with partially para-legal reservedness. This also goes for those frantic attempts to institute socalled ''norm selections'', and for efforts of attempting to influence objective rights by modifying grounds for contestation. What is needed is a legistation that, especially in the area of large industrial plants, exerts appropriate statuatory influence. So far, this has not been the case. It is up to the legislation to define permission standards, have them assessed and judged by experts, and harmonize them with the appropriate procedural rights. If this is done, the power of balance with regards to large industrial plants will be re-established. Curtailment of the lengthy process of official channels must also be considered. If a preliminary administrative procedure is already formalized, a second fact-establishing instance should be waived. (orig./HP) [de

    's own conduct embodied either in the commission of a criminal offence or in the omission to act. Therefore, contemporary criminal laws have determined special types of criminal sanctions, such as: punishment, security measures, conditional (suspended sentence and confiscation of material gain obtained by comitting the criminal offence, as well as the instruments, proceedings and conditions under which they may be imposed. Within the framework of the forthcoming reform of the entire penal legislation in the Republic of Serbia, the Serbian legislator may use the legal solutions envisaged in the analyzed documents and criminal legislations as a solid model for implementing the international standards in the field of criminal liability of legal entities. Hence, this paper discusses the particularities governing the application of criminal sanctions for legal entities in the Republic of Serbia, particularly as an instrument of crime control.

    Full Text Available The fiscal anti-fraud control has been regulated quite recently, by the Government Emergency Ordinance No. 74/2013, adopted in the context of the implementation of the “Project for the modernization of the fiscal administration” and the intensification of the fight against tax evasion. On the basis of the legal norms applying to it, of specialized doctrine and legal literature, the present work aims to approach fiscal control from various perspectives – organization, enforcement and definition of legal accountability – so as to point at the same time its specific forms, in relation to other similar control forms. Moreover, the present work will also analyse the novelty elements which the law brings, so as to create a specific technical support for the authorities, regarding those case laws having as object the economic-financial frauds. The current study aims to delineate the legal regime of this control form, which we consider a specialized activity, organized within the National Agency of Fiscal Administration and performed with the specific target of control, so as to prevent, acknowledge and fight tax evasion. At the same time, the present study is useful under the present circumstances, in which fiscal fraud has become more intense, becoming a phenomenon, but also because fiscal fraud has incidence upon other field of economic and financial interest.

    The Belgian law legalizing euthanasia under strict conditions came into effect September 22, 2002. Any physician performing euthanasia has to complete a registration document and to send it within four days to a federal commission whose mission is to verify that the legal conditions were fulfilled. From September 22, 2002 to December 31, 2013, 8.767 documents have been registered and analyzed by this commission. They are described in six reports referred to Parliament. The present paper analyzes the work of this commission and answers the criticisms concerning its quality and its efficiency. The allegations that clandestine euthanasia's escaping any control are performed are also discussed. In conclusion, it appears that the legal obligations concerning the practice of euthanasia in Belgium are fully effective.

    Web and attendant e-Commerce phenomena are irretrievably at odds with the traditional structure and hence legal regulation of health delivery. E-Health delivers healthcare information, diagnosis, treatment, care, and prescribing of drugs in a nonlinear, nonhierarchical manner that encourages patients to "enter" the system at an infinite number of points, thus defying current regulatory constructs. Similarly, e-Commerce fundamentals such as disintermediation and disaggregation result in medical information being delivered through unfamiliar channels, creating immensely difficult questions for health lawyers.

    1981-01-01

    The principle derived from experience that large projects require approval by the courts may not longer be valid. On the contrary, the courts are only entitled to real legal control according to the principle of the division of powers. If not accurately defined legal terms cannot be waived, the administration has to set the frame for review by courts by technical standards to be given in statutory ordinances, administrative provisions and administrative instructions. The average term of administrative proceedings has to be shortened considerably. The plaintiff as well as the beneficiaries of the act of licensing have a right to a prompt decision. The immediate execution of a decision can, on principle, also not be waived in future. More than up to now, the careful consideration of the interests and not an anticipated judgement on the main issue has to be the subject of legal examination according to section 80, subsection 5 of the German code of administrative procedure (Verwaltungsgerichtsordnung).

    1963-01-01

    The great importance of the fresh ground-water resources of Michigan is evident because 90 percent of the rural and about 70 percent of the total population of the State exclusive of the Detroit metropolitan area are supplied from underground sources. The water-supply and public-health problems that have been caused by some cases of ground-water contamination in the State illustrate the necessity of protecting this vital resource.Manmade and natural contaminants, including many types of chemical and organic matter, have entered many of the numerous aquifers of the State. Aquifers have been contaminated by waste-laden liquids percolating from the surface or from the zone of aeration and by direct injection to the aquifer itself. Industrial and domestic wastes, septic tanks, leaking sewers, flood waters or other poor quality surface waters, mine waters, solids stored or spread at the surface, and even airborne wastes all have been sources of ground-water contamination in Michigan. In addition, naturally occurring saline waters have been induced into other aquifers by overpumping or unrestricted flow from artesian wells, possibly by dewatering operations, and by the deepening of surface stream channels. Vertical migration of saline waters through open holes from formations underlying various important aquifers also has spoiled some of the fresh ground waters in the State. In spite of the contamination that has occurred, however, the total amount of ground water that has been spoiled is only a small part of the total resource. Neither is the contamination so widespread as that of the surface streams of Michigan.Overall legal authority to control most types of ground-water contamination in the State has been assigned by the Michigan Legislature to the Water Resources Commission, although the Department of Conservation and the Health Department also exercise important water-pollution control functions.

    2011-01-01

    Full Text Available The experiences and the practice of many countries show that countertrade could be used as the significant method for incensement of the export as well as for the promotion of the foreign investments even in the period of deep financial crises. Contemporary governments' pro-active countertrade orientation in USA, Israel, Sweden, Norway, Japan and other developed countries highlights the inadequacy of the obsolete and stereotypical concept of the countertrade as the compensation transaction based on the 'trade without money' concept. Besides this, the practices proved that countertrade transactions are the consequence and the indicator of economic shocks. Therefore, the study of the special legal issues that may arise in countertrade transactions will be very important not only for the domestic legal doctrine but also for the commercial practice. As national laws do not contain provisions specific for countertrade, it is of particular importance to analyze legal question such as structuring and drafting of countertrade arrangements as well as to study the question of the legal nature of the contractual link between legal instruments which form multicontractual mechanism of countertrade transactions. The character of the legal connection among the legal instruments in countertrade arrangement, as well as the legal nature of the countertrade commitment, strongly influence the countertrade agreement's legal nature. The economic reality of a group of contracts joined by the common goal of the transaction (consideration and the countertrade commitment has to be followed by the legal reality which will recognize the legal interdependence of the obligation deriving from the legally independent countertrade arrangement.

  17. The Legal Structure of Taiwan’s Wetland Conservation Act

    Yi-Yuan Su

    2014-12-01

    Full Text Available In July of 2013, Taiwan passed its Wetland Conservation Act and will begin the implementation of the Act on 2 February 2015. With this Act, Taiwan has become the second Asian country to have specific legislation on wetland conservation and protection. This new law enables the society to achieve sustainable utilization on wetland ecological services. The core concepts of the Wetland Conversation Act include biological diversity conservation and wise use of wetland resources. Special political circumstances prevent Taiwan from registering its wetlands as a conservation priority under the Ramsar Convention. This new law allows the government to evaluate and assign a specific area as a “Wetland of Importance.” Under this status, any development activities within the designated area shall be prohibited unless the developer prepares a usage plan for review. The usage plan and the original usage of the natural resources within the wetland area shall also follow the “wise use” principle to protect the wetland and biological service system. However, this new law does not provide clear separation between the two different “wise use” standards. If the development is deemed necessary, new law provides compensation mitigation measures to extend the surface of the wetland and provides additional habitats for various species. Wetland conservation and management rely heavily on systematic research and fundamental data regarding Taiwan’s wetlands. Determining how to adopt these scientific methodologies and transfer them into enforceable mechanisms is a sizeable challenge for both biologists and lawyers as the Wetland Conservation Act creates many legal norms without clarifying definitions. This article will review the current wetland regulations from the legal perspective and provide suggestions for enforcement in the future.

    On November 6, 1986, President Reagan signed a comprehensive immigration bill that prohibits the hiring of illegal aliens and offers legal status to many such aliens already in the US. The bill offers legal status to aliens who could show that they entered the US before January 1, 1982, and have resided here continuously "in an unlawful status" since that date. Employers hiring illegal aliens are subject to civil penalties ranging from $250 to $10,000 for each illegal alien. This summary of the Immigration Reform and Control Act of 1986 is based on the joint Senate/House Conference Report adopted by the House of Representatives on October 15, 1986.

    The purpose of this study was to examine the ways in which abuse that occurred during marriage/relationship continued within divorce and custody-related legal proceedings. Twenty-seven women participated in semistructured interviews. Interviews were analyzed utilizing a grounded theory approach in order to inductively arrive at a theory explaining how abuse dynamics may continue during legal proceedings. Participants identified child support litigation, custody and visitation battles, intimidation/harassment, deliberately prolonging the case, manipulating finances, and distortions of information as methods by which their exes sought to maintain power and control. Counseling implications are described.

    Yoder, Tommy; Greene, Ben; Porter, Alan

    2015-01-01

    Carbon composite structures are widely used in virtually all advanced technology industries for a multitude of applications. The high strength-to-weight ratio and resistance to aggressive service environments make them highly desirable. Automotive, aerospace, and petroleum industries extensively use, and will continue to use, this enabling technology. As a result of this broad range of use, field and test personnel are increasingly exposed to hazards associated with these structures. No single published document exists to address the hazards and make recommendations for the hazard controls required for the different exposure possibilities from damaged structures including airborne fibers, fly, and dust. The potential for personnel exposure varies depending on the application or manipulation of the structure. The effect of exposure to carbon hazards is not limited to personnel, protection of electronics and mechanical equipment must be considered as well. The various exposure opportunities defined in this document include pre-manufacturing fly and dust, the cured structure, manufacturing/machining, post-event cleanup, and post-event test and/or evaluation. Hazard control is defined as it is applicable or applied for the specific exposure opportunity. The carbon exposure hazard includes fly, dust, fiber (cured/uncured), and matrix vapor/thermal decomposition products. By using the recommendations in this document, a high level of confidence can be assured for the protection of personnel and equipment.

    2018-01-01

    Full Text Available According to the European Commission data, 8–12% of patients cared for in hospitals throughout the European Union have suffered accidents related to the healthcare provided for them. The Directive 2011/24/EU of the European Parliament and Council of 9th March 2011 on the application of patients’ rights in cross-border healthcare provides that the Member States shouldensurethat patients have easily accessible and transparent appeal procedures and mechanisms that provide possibilities for legal remedies in cases of inflicted harm during medical treatment according to regulations of the respective Member State. Healthcare quality control mechanisms are intended for two major purposes: to identify accidents that have occurred during medical treatment and to prevent similar accidents from reoccurring in the future. The aim of this article is to evaluate, firstly, the procedural aspects of healthcare quality control mechanisms in Latvia and, secondly, how healthcare quality control mechanisms have been affected with the implementation of the Directive 2011/24/EU in Latvian legal order, providing for a specific legal remedy – the newly created Medical risk fund. Conclusions are made on the procedural nature of the patients’ right to submit complaints and also the developments in Latvian court practice related to the healthcare quality control. The authors have also analysed regulations related to the Medical risk fund, its influence on the civil liability mechanisms of medical practitioners, as well as the patient’s right to obtainjust compensation for the harm inflicted to his health and the legal nature of opinions of the Health Inspectorate of Latvia.

    Miller, Chris J.

    2014-01-01

    The problem of control command and maneuver induced structural loads is an important aspect of any control system design. Designers must design the aircraft structure and the control architecture to achieve desired piloted control responses while limiting the imparted structural loads. The classical approach is to build the structure with high margins, restrict control surface commands to known good combinations, and train pilots to follow procedural maneuvering limitations. With recent advances in structural sensing and the continued desire to improve safety and vehicle fuel efficiency, it is both possible and desirable to develop control architectures that enable lighter vehicle weights while maintaining and improving protection against structural damage.

    2012-03-01

    The purpose of this article is to describe the legal framework for controlling mosquito vectors of diseases transmissible to human beings in certain locations such as Reunion Island. A distinction is made between general legal measures for insect vector control and specific measures for mosquito control. Regionalization is a major factor in the legal framework for insect vector control, thus limiting the scope of action by the prefecture. Another factor involves the increasing role of an important new player, i.e., the regional health agencies. Mosquito vector control raises the need to impose and enforce measures on the general public as well as private citizens. Failure to comply with these measures is punishable by sanctions and fines with no diminishing effect on de jure implementation of control measures by public agencies.

  17. The essential elements and the legal structure of master franchise agreement: How to draft a good contract?

    Directory of Open Access Journals (Sweden)

    Kerković-Milenković Tamara

    2010-01-01

    Full Text Available The creation of the draft and other legal documents in franchising transaction emanates the one of the most stressful challenge for the civil law lawyer. There are many reasons which create big obstacles in process of successfully drafting master franchise agreement. One of the main difficulties faced by the parties engaged in international trade is the lack of uniformed rules for the franchising agreement as well as franchising being anonymous contract in the most of legal systems of the world. Besides that, the franchise (emanating goodwill as the legal object of the franchising agreement is sui generis and fluid derives from the various numbers of rights and licence simmilar to right, such as trade names, trade marks and the shop signs, logos, utility models, designs, copyrights, know-how, etc. The legal structure of the mutual rights and obligations of the parties is extremely sophisticated not only because of the big number of obligations but because of their varieties and complexity. In most of the legal systems of common law as well as in the civil law countries the master franchise contract is not regulated neither with mandatory nor through dispositive norms of relationship laws but at the same time the franchise arrangements are subjected to a considerable number of laws and regulations from different areas of law, majority of which are regulated domestically and at the same time also at international legal context. Those areas of law are general contract law, agency law, leasing and security interests, intelectual property and competiton law, corporate law, insurance and labore law, consumer protection and product liability legislation and always important industry specific laws. In interantional legal practice there are many so-called template franchise agreement which are prepared from the franchisor in advance regulating all possible predictable legal solution and legislation. But, it is advisable for the civil law lawyer to treat

  18. The medical practice of euthanasia in Belgium and The Netherlands: legal notification, control and evaluation procedures.

    To describe and compare current legal procedures for notifying, controlling and evaluating (NCE-procedures) euthanasia in Belgium and the Netherlands, and to discuss the implications for a safe and controllable euthanasia practice. We systematically studied and compared official documents relating to the Belgian and the Dutch NCE-procedures for euthanasia. In both countries, physicians are required to notify their cases to a review Committee, stimulating them to safeguard the quality of their euthanasia practice and to make societal control over the practice of euthanasia possible. However, the procedures in both countries differ. The main differences are that the Dutch notification and control procedures are more elaborate and transparent than the Belgian, and that the Belgian procedures are primarily anonymous, whereas the Dutch are not. Societal evaluation is made in both countries through the Committees' summary reports to Parliament. Transparent procedures like the Dutch may better facilitate societal control. Informing physicians about the law and the due care requirements for euthanasia, and systematic feedback about their medical actions are both pivotal to achieving efficient societal control and engendering the level of care needed when performing such far-reaching medical acts.

  20. Legal and social control of alcohol-impaired driving in California: 1983-1994.

    Science.gov (United States)

    Berger, D E; Marelich, W D

    1997-09-01

    This research was designed to provide information on the legal and social forces that influence change in control of alcohol-impaired driving. Attitudes, perceptions and behaviors concerning drinking and driving for California drivers in 1994 (n = 608) were compared to similar information collected from California drivers in 1983 and 1986 (n = 291) through random-digit-dialing telephone interviews. Self-reported drinking-driving violations showed a substantial decline, paralleling the well-documented drop in alcohol-related traffic crashes during this time span. A large reduction in drinking before driving was reported for all age groups, men and women, and for both heavy drinkers and light drinkers. There was evidence of an increase in the levels of both general deterrence and general prevention. Increased external control was reflected in greater knowledge of drinking-driving laws and trends toward an increased expectation that violations would be followed by unpleasant consequences. Strong gains in creating a social norm for control of alcohol-impaired driving were indicated by perceptions that friends and relatives were more likely to disapprove of driving after drinking, observations of more control of drinking by drivers at occasions where alcohol is served and an increase in the view that it is morally wrong to drive after heavy drinking. California has made substantial progress in efforts to control alcohol-impaired driving, through increases in both general deterrence (fear of punishment) and general prevention (moral inhibitions and socialization of preventive habits), especially the latter.

  1. Earthquake design for controlled structures

    Directory of Open Access Journals (Sweden)

    Nikos G. Pnevmatikos

    2017-04-01

    Full Text Available An alternative design philosophy, for structures equipped with control devices, capable to resist an expected earthquake while remaining in the elastic range, is described. The idea is that a portion of the earthquake loading is under¬taken by the control system and the remaining by the structure which is designed to resist elastically. The earthquake forces assuming elastic behavior (elastic forces and elastoplastic behavior (design forces are first calculated ac¬cording to the codes. The required control forces are calculated as the difference from elastic to design forces. The maximum value of capacity of control devices is then compared to the required control force. If the capacity of the control devices is larger than the required control force then the control devices are accepted and installed in the structure and the structure is designed according to the design forces. If the capacity is smaller than the required control force then a scale factor, α, reducing the elastic forces to new design forces is calculated. The structure is redesigned and devices are installed. The proposed procedure ensures that the structure behaves elastically (without damage for the expected earthquake at no additional cost, excluding that of buying and installing the control devices.

    2012-07-01

    The publication provides a systematic outline of the legal boundary conditions governing the operation of electric power supply grids. It goes beyond mere regulatory aspects, covering also the projecting and construction of grids, the acquisition or leasing of land for power transmission line construction, operating licenses and utility certification, the organisational structure and purpose of electric utilities, as well as the operating, servicing and enhancement of electricity grids including calculation of electricity rates. In addition to this systematic outline of legal aspects, it is investigated how the balance between entrepreneurial responsibility and state control was defined in the EnWG 2011, and it is discussed if the law provides sufficient room for entrepreneurial decisions.

  3. Social, economic and legal dimensions of tobacco and its control in South-East Asia region.

    Kyaing, Nyo Nyo; Islam, Md Ashadul; Sinha, Dhirendra N; Rinchen, Sonam

    2011-01-01

    This paper examines the social, cultural, economic and legal dimensions of tobacco control in the South-East Asia Region in a holistic view through the review of findings from various studies on prevalence, tobacco economics, poverty alleviation, women and tobacco and tobacco control laws and regulations. Methods were Literature review of peer reviewed publications, country reports, WHO publications, and reports of national and international meetings on tobacco and findings from national level surveys and studies. Tobacco use has been a social and cultural part of the people of South-East Asia Region. Survey findings show that 30% to 60% of men and 1.8% to 15.6% of women in the Region use one or the other forms of tobacco products. The complex nature of tobacco use with both smoking and smokeless forms is a major challenge for implementing tobacco control measures. Prevalence of tobacco use is high among the poor and the illiterate. It is higher among males than females but studies show a rising trend among girls and women due to intensive marketing of tobacco products by the tobacco industry. Tobacco users spend a huge percent of their income on tobacco which deprives them and their families of proper nutrition, good education and health care. Some studies of the Region show that cost of treatment of diseases attributable to tobacco use was more than double the revenue that governments received from tobacco taxation. Another challenge the Region faces is the application of uniform tax to all forms of tobacco, which will reduce not only the availability of tobacco products in the market but also control people switching over to cheaper tobacco products. Ten out of eleven countries are Parties to the WHO Framework Convention on Tobacco Control and nine countries have tobacco control legislation. Enforcement of control measures is weak, particularly in areas such as smoke-free environments, advertisement at the point of sale and sale of tobacco to minors. Socio

  5. The right to have a family: 'legal trafficking of children', adoption and birth control in Brazil.

    Science.gov (United States)

    Cardarello, Andrea

    2012-01-01

    This paper focuses on one of the 'child-trafficking scandals' that occurred in Brazil in the 1990s. Ethnographic research was carried out between 2000 and 2001 within a movement of poor families formed in São Paulo to put pressure on the authorities to review the legal procedures that had led to their children being placed for national and international adoption. Fieldwork was supplemented by other data, including reports by legislative bodies, articles in the press, and case files involving the termination of parental rights. This paper explores views on international adoption among members of the Brazilian elites such as judges, agents in the field of child protection and journalists, in the context of old but persistent neo-Malthusian ideas. Although the Brazilian birth rate is now below the replacement level, it is still common to blame 'irresponsible' reproduction among the urban poor for violence in large cities. Drawing a parallel with the routine sterilization of women that prevailed for decades and was encouraged by Brazilian physicians, the paper examines how, in a 'struggle against poverty', judicial agents took it upon themselves to enforce 'birth control' through adoption, bypassing family consent and the law in the process. The paper concludes by arguing that discrimination against poor families who are viewed as disorganized, immoral and irresponsible - characteristics frequently associated with criminality by a sector of the elites - has contributed to the view that lower-class families do not have the right to bear children, or to keep them.

    2015-10-01

    Cognitive function is driven by dynamic interactions between large-scale neural circuits or networks, enabling behaviour. However, fundamental principles constraining these dynamic network processes have remained elusive. Here we use tools from control and network theories to offer a mechanistic explanation for how the brain moves between cognitive states drawn from the network organization of white matter microstructure. Our results suggest that densely connected areas, particularly in the default mode system, facilitate the movement of the brain to many easily reachable states. Weakly connected areas, particularly in cognitive control systems, facilitate the movement of the brain to difficult-to-reach states. Areas located on the boundary between network communities, particularly in attentional control systems, facilitate the integration or segregation of diverse cognitive systems. Our results suggest that structural network differences between cognitive circuits dictate their distinct roles in controlling trajectories of brain network function.

  12. Structured control for autonomous robots

    International Nuclear Information System (INIS)

    Simmons, R.G.

    1994-01-01

    To operate in rich, dynamic environments, autonomous robots must be able to effectively utilize and coordinate their limited physical and occupational resources. As complexity increases, it becomes necessary to impose explicit constraints on the control of planning, perception, and action to ensure that unwanted interactions between behaviors do not occur. This paper advocates developing complex robot systems by layering reactive behaviors onto deliberative components. In this structured control approach, the deliberative components handle normal situations and the reactive behaviors, which are explicitly constrained as to when and how they are activated, handle exceptional situations. The Task Control Architecture (TCA) has been developed to support this approach. TCA provides an integrated set of control constructs useful for implementing deliberative and reactive behaviors. The control constructs facilitate modular and evolutionary system development: they are used to integrate and coordinate planning, perception, and execution, and to incrementally improve the efficiency and robustness of the robot systems. To date, TCA has been used in implementing a half-dozen mobile robot systems, including an autonomous six-legged rover and indoor mobile manipulator

    This paper assesses the authority of precedent from a phenomenological standpoint. Phenomenology distinguishes between two temporal models. One describes time in an idealised form, as a divisible chain of instants or events. The other looks at lived temporality as fluid and indivisible duration. In the system of precedent, we witness an interaction of both models. The legal order is constructed from slices in time that become the building blocks of future judgments. Precedents are binding for...

  1. Human rights versus legal control over women's reproductive self-determination.

    Science.gov (United States)

    Uberoi, Diya; de Bruyn, Maria

    2013-06-14

    States have a duty under international human rights law to protect people's health. Nonetheless, while some health-related policies and laws protect basic human rights, others violate fundamental rights when they criminalize, prohibit, and restrict access to necessary health services. For example, laws and regulations related to protection of life from conception, contraception, actions of pregnant women, and abortion can harm women and place women and health care providers in jeopardy of legal penalization. Given the adverse consequences of punitive and restrictive laws related to pregnancy, advocates, civil society groups, human rights groups, and government institutions must work together to promote, protect, and fulfill women's fundamental reproductive rights.

    2008-09-01

    This study assessed volatile organic compound (VOC) emission characteristics from wastewater treatment plants (WWTPs) in five Taiwanese industrial districts engaged in numerous manufacturing processes, including petrochemical, science-based industry (primarily semiconductors, photo-electronics, electronic products and biological technology), as well as multiple manufacturing processes (primarily pharmaceuticals and paint manufacturing). The most aqueous hydrocarbons dissolved in the wastewater of Taiwanese WWTPs were acetone, acrylonitrile, methylene chloride, and chloroform for the petrochemical districts; acetone, chloroform, and toluene for the science-based districts; and chlorinated and aromatic hydrocarbons for the multiple industrial districts. The aqueous pollutants in the united WWTPs were closely related to the characteristics of the manufacturing plants in the districts. To effectively prevent VOC emissions from the primary treatment section of petrochemical WWTPs, the updated regulations governing VOC emissions were issued by the Taiwanese Environmental Protection Administration in September 2005, legally mandating a seal cover system incorporating venting and air purification equipment. Cost analysis indicates that incinerators with regenerative heat recovery are optimal for treating high VOC concentrations, exceeding 10,000 ppm as CH(4), from the oil separation basins. However, the emission concentrations, ranging from 100 to 1,000 ppm as CH(4) from the other primary treatment facilities and bio-treatment stages, should be collected and then injected into the biological oxidation basins via existing or new blowers. The additional capital and operating costs required to treat the VOC emissions of 1,000 ppm as CH(4) from primary treatment facilities are less than USD 0.1 for per m(3) wastewater treatment capacity.

  4. Integrated structural control design of large space structures

    Allen, J.J.; Lauffer, J.P.

    1995-01-01

    Active control of structures has been under intensive development for the last ten years. Reference 2 reviews much of the identification and control technology for structural control developed during this time. The technology was initially focused on space structure and weapon applications; however, recently the technology is also being directed toward applications in manufacturing and transportation. Much of this technology focused on multiple-input/multiple-output (MIMO) identification and control methodology because many of the applications require a coordinated control involving multiple disturbances and control objectives where multiple actuators and sensors are necessary for high performance. There have been many optimal robust control methods developed for the design of MIMO robust control laws; however, there appears to be a significant gap between the theoretical development and experimental evaluation of control and identification methods to address structural control applications. Many methods have been developed for MIMO identification and control of structures, such as the Eigensystem Realization Algorithm (ERA), Q-Markov Covariance Equivalent Realization (Q-Markov COVER) for identification; and, Linear Quadratic Gaussian (LQG), Frequency Weighted LQG and H-/ii-synthesis methods for control. Upon implementation, many of the identification and control methods have shown limitations such as the excitation of unmodelled dynamics and sensitivity to system parameter variations. As a result, research on methods which address these problems have been conducted.

    1978-10-01

    Through both interviews with primary and secondary mortgage market lending institutions and a search of the relevant literature, the major concerns and attitudes of financial institutions toward solar homes are reviewed, unique problems encountered in making loans on such structures are discussed and special requirements placed upon solar home loans are explored. At present, these are seen as centered around: (1) placing an appropriate valuation on a solar-heated home, (2) assessing the technical feasibility of a solar energy system, and (3) determining what energy savings might accrue through installation of a solar energy system and how such savings can best be integrated into the lending process. Some of the most pertinent literature on this subject is reviewed and the goals to be strived for in protecting solar access are set forth. Negative solar easements and restrictive covenants are seen as the most appropriate legal tools for assuring adequate solar access. Seven elements which must be addressed when describing the air space to be protected by an effective easement or covenant are identified. Appendices are included which show how one innovative lending institution has developed a policy for financing solar homes based upon these elements. Problems with regard to obtaining title insurance are discussed, and the enforceability and transferability of solar access rights are detailed.

    Objective: Research on supervisor social control provided little evidence for a relation to employee alcohol use, and only one study explored illicit drug use. Based on past research, several hypotheses were developed that the relation between supervisor social control and substance use depends on (a) the dimension social control (contact vs. enforcement), (b) the temporal context of substance use (on the job vs. off the job), and (c) substance legality (alcohol vs. illicit drugs). Method: Data came from a national probability sample of U.S. workers. Supervisor social control represented both supervisor contact and supervisor enforcement. Measures of alcohol and illicit drug use each assessed several dimensions of off-the-job use (overall use, overall impairment, and use after work) and on-the-job use (use before work, use during the workday, and impairment during the workday). Results: As hypothesized, the results did not support a relation of supervisor contact to off-the-job or on-the-job alcohol use and illicit drug use. Supervisor enforcement was unrelated to off-the-job alcohol use but was negatively related to on-the-job alcohol use. Supervisor enforcement was negatively related to both off-the-job and on-the-job illicit drug use. Conclusions: These findings help clarify the generally unsupportive findings from past research for a relation between supervisor social control and employee alcohol use, as well as extend this line of research to include illicit drug use. The results suggest that to fully understand the relation of supervisor social control to employee substance use, one must consider the dimension of supervisor social control, temporal context of substance use, and substance legality.

    Purpose: To enable stable reactor core control even in extremely great vertical earthquakes, as well as under normal operation conditions in FBR type reactors. Constitution: Since a mechanism for converting the rotational movement of a control rod into vertical movement is placed at the upper portion of the reactor core at high temperature, the mechanism should cause fusion or like other danger after the elapse of a long period of time. In view of the above, the conversion mechanism is disposed to the lower portion of the reactor core at a lower temperature region. Further, the connection between the control rod and the control rod drive can be separated upon great vertical earthquakes. (Seki, T.)

    Disclosed is a method and system for actively controlling the shape of a sheet of electroactive material; the system comprising: one or more electrodes attached to the frontside of the electroactive sheet; a charged particle generator, disposed so as to direct a beam of charged particles (e.g. electrons) onto the electrode; a conductive substrate attached to the backside of the sheet; and a power supply electrically connected to the conductive substrate; whereby the sheet changes its shape in response to an electric field created across the sheet by an accumulation of electric charge within the electrode(s), relative to a potential applied to the conductive substrate. Use of multiple electrodes distributed across on the frontside ensures a uniform distribution of the charge with a single point of e-beam incidence, thereby greatly simplifying the beam scanning algorithm and raster control electronics, and reducing the problems associated with "blooming". By placing a distribution of electrodes over the front surface of a piezoelectric film (or other electroactive material), this arrangement enables improved control over the distribution of surface electric charges (e.g. electrons) by creating uniform (and possibly different) charge distributions within each individual electrode. Removal or deposition of net electric charge can be affected by controlling the secondary electron yield through manipulation of the backside electric potential with the power supply. The system can be used for actively controlling the shape of space-based deployable optics, such as adaptive mirrors and inflatable antennae.

  20. Fuzzy logic for structural system control

    Directory of Open Access Journals (Sweden)

    Herbert Martins Gomes

    Full Text Available This paper provides some information and numerical tests that aims to investigate the use of a Fuzzy Controller applied to control systems. Some advantages are reported regarding the use of this controller, such as the characteristic ease of implementation due to its semantic feature in the statement of the control rules. On the other hand, it is also hypothesized that these systems have a lower performance loss when the system to be controlled is nonlinear or has time varying parameters. Numerical tests are performed using modal LQR optimal control and Fuzzy control of non-collocated systems with full state feedback in a two-dimensional structure. The paper proposes a way of designing a controller that may be a supervisory Fuzzy controller for a traditional controller or even a fuzzy controller independent from the traditional control, consisting on individual mode controllers. Some comments are drawn regarding the performance of these proposals in a number of arrangements.

  4. Clearing a Path Towards Effective Alien Invasive Control: the Legal Conundrum

    Directory of Open Access Journals (Sweden)

    2006-05-01

    Full Text Available Alien invasive plants pose significant ecological, social and economic challenges for South Africa. These species threaten South Africa’s rich biodiversity, deplete our scarce water resources, reduce the agricultural potential of land, cause soil erosion and intensify flooding and fires. According to recent estimations, over eight percent of land in South Africa has been invaded by these species and at current rates of expansion their impact could double in the next fifteen years. In an attempt to curb the impending crises, the South African government has promulgated eleven national and various provincial laws which contain mechanisms for regulating the different threats posed by alien invasive plants. Certain of these laws are framework in nature while the majority are sectoral and aimed at regulating these species for one of the following four main purposes: biodiversity conservation; water conservation; agricultural management; and fire risk management. The responsibility for administering these laws spans four national departments, nine provincial environmental authorities, provincial conservation authorities, numerous local and statutory authorities. This fragmented regime, coupled with the adoption of a command and control approach to regulation, has proven inept in effectively regulating the spread of alien invasive plants in South Africa. This reality led the previous Minister of Environmental Affairs and Tourism, Mr Valli Moosa, to call for the development of a “coherent legislative framework … streamlined along the lines of the principles endorsed by the Convention on Biological Diversity”. This article critically analyses the government’s attempts to develop such a “coherent legislative framework” to regulate alien invasive plants in light of recent legislative reform. It is divided into two parts. Part one critically considers South Africa’s current laws of relevance to alien invasive plants with specific emphasis on

    Little research has been done to examine whether smokers switch to illegal or roll-your-own (RYO) cigarettes in response to a change in their relative price. This paper explores how relative prices between three cigarette forms (manufactured legal, manufactured illegal and RYO cigarettes) are associated with the choice of one form over another after controlling for covariates, including sociodemographic characteristics, smokers' exposure to antismoking messaging, health warning labels and tobacco marketing. Generalised estimating equations were employed to analyse the association between the price ratio of two different cigarette forms and the usage of one form over the other. A 10% increase in the relative price ratio of legal to RYO cigarettes is associated with a 4.6% increase in the probability of consuming RYO cigarettes over manufactured legal cigarettes (p≤0.05). In addition, more exposure to antismoking messaging is associated with a lower odds of choosing RYO cigarettes over manufactured legal cigarettes (p≤0.05). Non-significant associations exist between the manufactured illegal to legal cigarette price ratios and choosing manufactured illegal cigarettes, suggesting that smokers do not switch to manufactured illegal cigarettes as prices of legal ones increase. However, these non-significant findings may be due to lack of variation in the price ratio measures. To improve the effectiveness of increased taxes and prices in reducing smoking, policymakers need to narrow price variability in the tobacco market. Moreover, increasing antismoking messaging reduces tax avoidance in the form of switching to cheaper RYO cigarettes in Uruguay. Published by the BMJ Publishing Group Limited.

  13. Design, optimization, and control of tensegrity structures

    Science.gov (United States)

    Masic, Milenko

    The contributions of this dissertation may be divided into four categories. The first category involves developing a systematic form-finding method for general and symmetric tensegrity structures. As an extension of the available results, different shape constraints are incorporated in the problem. Methods for treatment of these constraints are considered and proposed. A systematic formulation of the form-finding problem for symmetric tensegrity structures is introduced, and it uses the symmetry to reduce both the number of equations and the number of variables in the problem. The equilibrium analysis of modular tensegrities exploits their peculiar symmetry. The tensegrity similarity transformation completes the contributions in the area of enabling tools for tensegrity form-finding. The second group of contributions develops the methods for optimal mass-to-stiffness-ratio design of tensegrity structures. This technique represents the state-of-the-art for the static design of tensegrity structures. It is an extension of the results available for the topology optimization of truss structures. Besides guaranteeing that the final design satisfies the tensegrity paradigm, the problem constrains the structure from different modes of failure, which makes it very general. The open-loop control of the shape of modular tensegrities is the third contribution of the dissertation. This analytical result offers a closed form solution for the control of the reconfiguration of modular structures. Applications range from the deployment and stowing of large-scale space structures to the locomotion-inducing control for biologically inspired structures. The control algorithm is applicable regardless of the size of the structures, and it represents a very general result for a large class of tensegrities. Controlled deployments of large-scale tensegrity plates and tensegrity towers are shown as examples that demonstrate the full potential of this reconfiguration strategy. The last

    The objectives of this research were to develop techniques of controlling a dc-motor driven flywheel which would apply torque to the structure to which it was mounted. The motor control system was to be implemented using a microprocessor based controller. The purpose of the torque applied by this system was to dampen oscillations of the structure to which it was mounted. Before the work was terminated due to the unavailability of equipment, a system was developed and partially tested which would provide tight control of the flywheel velocity when it received a velocity command in the form of a voltage. The procedure followed in this development was to first model the motor and flywheel system on an analog computer. Prior to the time the microprocessor development system was available, an analog control loop was replaced by the microprocessor and the system was partially tested.

    Full Text Available Today’s databases store information with sensitivity levels that range from public to highly sensitive, hence ensuring confidentiality can be highly important, but also requires costly control. This paper focuses on the inference problem on different database structures. It presents possible treats on privacy with relation to the inference, and control methods for mitigating these treats. The paper shows that using only access control, without any inference control is inadequate, since these models are unable to protect against indirect data access. Furthermore, it covers new inference problems which rise from the dimensions of new technologies like XML, semantics, etc.

    The purpose of this exploratory study was to examine the effects of legal name change on socioeconomic factors, general and transgender-related healthcare access and utilization, and transgender-related victimization in a sample of young transgender women (transwomen) of color. A cross-sectional group comparison approach was used to assess the potential effects of legal name change. A convenience sample of young transwomen enrolled in a no-cost legal name change clinic were recruited to complete a 30-minute interviewer-guided telephone survey including sociodemographic and socioeconomic factors, health and well-being, health care utilization, transgender transition-related health care, and transgender-related victimization. Sixty-five transgender women of color (37 = pre-name change group; 28 = post-name change group) completed the survey. Results indicated that the transwomen in the post-name change group were significantly older than the pre-name change group. In age-adjusted analyses, the post-name change group was significantly more likely to have a higher monthly income and stable housing than the pre-name change group. No significant differences were observed for general healthcare utilization; however, a significantly greater percentage of transwomen in the pre-name change group reported postponing medical care due to their gender identity. In addition, a significantly larger proportion of transwomen in the pre-name change group reported using non-prescribed hormones injected by friends and experiencing verbal harassment by family and friends compared to transwomen in the post-name change group. Findings suggest that legal name change may be an important structural intervention for low-income transwomen of color, providing increased socioeconomic stability and improved access to primary and transition-related health care.

    In Germany, the guardianship system provides adults who are no longer able to handle their own affairs a court-appointed legal representative, for support without restriction of legal capacity. Although these representatives only rarely are qualified in healthcare, they nevertheless play decisive roles in the decision-making processes for people with dementia. Previously, we developed an education program (PRODECIDE) to address this shortcoming and tested it for feasibility. Typical, autonomy-restricting decisions in the care of people with dementia-namely, using percutaneous endoscopic gastrostomy (PEG) or physical restrains (PR), or the prescription of antipsychotic drugs (AP)-were the subject areas trained. The training course aims to enhance the competency of legal representatives in informed decision-making. In this study, we will evaluate the efficacy of the PRODECIDE education program. A randomized controlled trial with a six-month follow-up will be conducted to compare the PRODECIDE education program with standard care, enrolling legal representatives (N = 216). The education program lasts 10 h and comprises four modules: A, decision-making processes and methods; and B, C and D, evidence-based knowledge about PEG, PR and AP, respectively. The primary outcome measure is knowledge, which is operationalized as the understanding of decision-making processes in healthcare affairs and in setting realistic expectations about benefits and harms of PEG, PR and AP in people with dementia. Secondary outcomes are sufficient and sustainable knowledge and percentage of persons concerned affected by PEG, FEM or AP. A qualitative process evaluation will be performed. Additionally, to support implementation, a concept for translating the educational contents into e-learning modules will be developed. The study results will show whether the efficacy of the education program could justify its implementation into the regular training curricula for legal representatives

However, the real systems represented by networks contain unreliable components and modern robust control engineering has not addressed the problem of structural changes on complex networks including scale-free topologies. Here, we introduce the concept of structurally robust control of complex networks and provide a concrete example using an algorithmic framework that is widely applied in engineering. The developed analytical tools, computer simulations, and real network analyses lead herein to the discovery that robust control can be achieved in scale-free networks with exactly the same order of controllers required in a standard nonrobust configuration by adjusting only the minimum degree. The presented methodology also addresses the probabilistic failure of links in real systems, such as neural synaptic unreliability in Caenorhabditis elegans, and suggests a new direction to pursue in studies of complex networks in which control theory has a role.

    The legal relationship is a patrimonial or non-patrimonial social relationship regulated by a rule of law. Any legal relationship is a social relationship, but not any social relationship is a legal relationship. The law maker has the power to select, of the multitude of human relationships, those who gives importance in terms of legal perspective, encoding them through legal regulations.

  8. HTA and its legal issues: a framework for identifying legal issues in health technology assessment.

    Widrig, Daniel; Tag, Brigitte

    2014-12-01

    Legal analysis can highlight important issues that are relevant when deciding whether a medical technology should be implemented or reimbursed. Literature and studies show that even though the law is an acknowledged part of health technology assessment (HTA), legal issues are rarely considered in practice. One reason for this may be the lack of knowledge about the diversity of legal issues that are relevant for HTA. Therefore, this contribution aims primarily to identify and then explain the relevant legal issues in HTA. This study offers a framework for identifying the legal issues in HTAs in different jurisdictions and provides a basis for further research. After extensive literature search, the authors review Swiss health law to identify legal issues that are relevant to HTA. The authors then categorize these legal issues using a framework with an inside and outside perspective. Finally, they explain a selection of these legal issues with several examples. This study reveals numerous legal issues that are relevant for HTA and underlines the necessity of incorporating legal analysis in HTAs. The suggested perspectival framework in this study provides a basis to structure the legal analysis. The identified legal issues are relevant in other countries and the perspectival framework is transferable to other jurisdictions. The article underlines the importance of in-depth discussion about the role of law in HTA. It provides a structured overview of the legal issues in HTA and suggests a development of more concrete instruments toward a standardized legal technology assessment.

    Full Text Available The process of introduction into our national legislation of norms of the European union legislation has a direct impact on the process of realization of major activities in all spheres of the public life and the activities related to medical services are not an exception. The management of activities, connected to provision of medical services, requires attention to be paid not only to the competitive environment, but also to the normative requirements, regulating the access of the citizens to medical aid. When talking about healthcare and healthcare market, it should be noted that good healthcare is possible only where there is good civil society and strong traditions in the field of social insurance. The new requirements introduced in the way of functioning of the healthcare system aim to provide improved human health, however simultaneously the adaptation of the system to the new legally regulated requirements should be implemented in a way, which guarantees fast and easy access to healthcare services for all patients.

    Grant, Jon E; Odlaug, Brian L; Davis, Andrew A; Kim, Suck Won

    2009-12-01

    Although studies have examined clinical characteristics of kleptomania, no previous studies have examined the legal consequences of kleptomania. From 2001 to 2007, 101 adult subjects (n = 27 [26.7%] males) with DSM-IV kleptomania were assessed on sociodemographics and clinical characteristics including symptom severity, comorbidity, and legal repercussions. Of 101 subjects with kleptomania, 73.3% were female. Mean age of shoplifting onset was 19.4 +/- 12.0 years, and subjects shoplifted a mean of 8.2 +/- 11.0 years prior to meeting full criteria for kleptomania. Co-occurring depressive, substance use, and impulse control disorders were common. Sixty-nine subjects with kleptomania (68.3%) had been arrested, 36.6% had been arrested but not convicted, 20.8% had been convicted and incarcerated after conviction, while only 10.9% had been convicted and not incarcerated after conviction. Kleptomania is associated with significant legal repercussions. The findings emphasize the need for rigorous treatment approaches to target kleptomania symptoms and prevent re-offending.

    This paper discusses how legal moralism should be defined. It is argued that legal moralism should be defined as the position that “For any X, it is always a pro tanto reason for justifiably imposing legal regulation on X that X is morally wrong (where “morally wrong” is not conceptually equivalent...... to “harmful”)”. Furthermore, a distinction between six types of legal moralism is made. The six types are grouped according to whether they are concerned with the enforcement of positive or critical morality, and whether they are concerned with criminalising, legally restricting, or refraining from legally...... protecting morally wrong behaviour. This is interesting because not all types of legal moralism are equally vulnerable to the different critiques of legal moralism that have been put forth. Indeed, I show that some interesting types of legal moralism have not been criticised at all....

  20. From Toques to Tokes: Two challenges facing nationwide legalization of cannabis in Canada.

    Science.gov (United States)

    Bear, Daniel

    2017-04-01

    In 2015, a new Liberal Government came to power in Canada, elected on a platform that included legalization and regulation of cannabis for recreational purposes. Their legislation, based on recommendations from a Federal Task Force on Marijuana Legalization and Regulation, is due in early April 2017. This commentary utilizes Canadian Federal policy papers, previous literature, and internal and international agreements to examine two key areas critical to the development of a nationwide regulated market for cannabis in Canada; the need to overcome restrictions to legalizing cannabis in United Nations' drug control treaties, and the unique challenges that non-medical cannabis creates for navigating interprovincial trade policies in Canada. Irrespective of UN conventions that appear to prohibit legalization of cannabis the Government is preparing to bring forward legislation as this article goes to print. At the same time significant squabbles impede the selling of even beer and wine inter-provincially in Canada. This paper identifies the challenges facing Canadian legalization efforts, but also shows how the legalization legislation may provide opportunities to engender significant change beyond the simple legalization of a specific drug. This commentary does not argue for any specific course of action for Canada, but rather explores the nuance of legalization absent from the declaration in the Liberal party platform. The paper argues that Canada's efforts may hasten the dismantling of the UN drug control structure, and provide renewed opportunities for intern-provincial trade in Canada.

  1. Experimental Validation of an Integrated Controls-Structures Design Methodology

    1996-01-01

    The first experimental validation of an integrated controls-structures design methodology for a class of large order, flexible space structures is described. Integrated redesign of the controls-structures-interaction evolutionary model, a laboratory testbed at NASA Langley, was described earlier. The redesigned structure was fabricated, assembled in the laboratory, and experimentally tested against the original structure. Experimental results indicate that the structure redesigned using the integrated design methodology requires significantly less average control power than the nominal structure with control-optimized designs, while maintaining the required line-of-sight pointing performance. Thus, the superiority of the integrated design methodology over the conventional design approach is experimentally demonstrated. Furthermore, amenability of the integrated design structure to other control strategies is evaluated, both analytically and experimentally. Using Linear-Quadratic-Guassian optimal dissipative controllers, it is observed that the redesigned structure leads to significantly improved performance with alternate controllers as well.

    1989-01-01

    To facilitate the development of control structure interaction (CSI) design methodology, a computational architecture for interdisciplinary design of active structures is presented. The emphasis of the computational procedure is to exploit existing sparse matrix structural analysis techniques, in-core data transfer with control synthesis programs, and versatility in the optimization methodology to avoid unnecessary structural or control calculations. The architecture is designed such that all required structure, control and optimization analyses are performed within one program. Hence, the optimization strategy is not unduly constrained by cold starts of existing structural analysis and control synthesis packages.

    Zhang, Xiang-Cheng; Xu, Zhao-Dong; Huang, Xing-Huai; Zhu, Jun-Tao

    2013-04-01

    The semi-active control technology has been paid more attention in the field of structural vibration control due to its high controllability, excellent control effect and low power requirement. When semi-active control device are used for vibration control, some challenges must be taken into account, such as the reliability and the control strategy of the device. This study presents a new large tonnage compound lead extrusion magnetorheological (CLEMR) damper, whose mathematical model is introduced to describe the variation of damping force with current and velocity. Then a current controller based on the fuzzy logic control strategy is designed to determine control currents of the CLEMR dampers rapidly. A ten-floor frame structure with CLEMR dampers using the fuzzy logic control strategy is built and calculated by using MATLAB. Calculation results show that CLEMR dampers can reduce the seismic responses of structures effectively. Calculation results of the fuzzy logic control strategy are compared with those of the semi-active limit Hrovat control structure, the passive-off control structure, and the uncontrolled structure. Comparison results show that the fuzzy logic control strategy can determine control currents of CLEMR dampers quickly and can reduce seismic responses of the structures more effectively than the passive-off control strategy and the uncontrolled structure.

    Many intervention efforts targeting student drinking were developed to address US college students, which usually involves underage drinking. It remains unclear, if research evidence from these interventions is generalizable to university and college students of legal drinking age, e.g., in Europe. To evaluate the effectiveness of a translated and adapted version of the eCHECKUP TO GO, applied as stand-alone web-based electronic screening and brief intervention (e-SBI), in German university students at risk for hazardous drinking. A fully automated web-based two-arm parallel-group randomized controlled trial was conducted. Participants were randomized to an e-SBI or assessment-only (AO) condition. The current paper analyzed students with baseline AUDIT-C scores ≥3 for women and ≥4 for men (sample at baseline: e-SBI [n=514], AO [n=467]; 3-month follow-up: e-SBI [n=194], AO [n=231]; 6-month follow-up: e-SBI [n=146], AO [n=200]). The primary outcome was prior four weeks' alcohol consumption. Secondary outcomes were frequency of heavy drinking occasions, peak blood alcohol concentration, and number of alcohol-related problems. Mixed linear model analyses revealed significant interaction effects between groups and time points on the primary outcome after 3 and 6months. Compared to students in the AO condition, students in the e-SBI condition reported consuming 4.11 fewer standard drinks during the previous four weeks after 3months, and 4.78 fewer standard drinks after 6months. Mixed results were found on secondary outcomes. The results indicate that evidence on and knowledge of web-based e-SBIs based on US college student samples is transferable to German university students of legal drinking age. However, knowledge of what motivates students to complete programs under voluntary conditions, although rare, is needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  14. Legal aspects of the control and repression of illicit trafficking of nuclear and other radioactive materials. Is there a need for an international convention?

    International Nuclear Information System (INIS)

    Spence, Scott

    2012-01-01

    It is generally recognised that illicit trafficking of nuclear and other radioactive materials is a serious problem, and one that must be tackled with a comprehensive response involving national governments as well as a number of intergovernmental organisations including the International Atomic Energy Agency (IAEA). The IAEA notes that 1 773 incidents were reported to its Illicit Trafficking Database, or ITDB, between January 1993 and December 2009, and that 351 of these involved '... unauthorized possession and related criminal activities' such as '... illegal possession, movement or attempts to illegally trade in or use nuclear material or radioactive sources'. The IAEA adds that 222 more incidents were confirmed between July 2009 and June 2010 and concludes that: - the availability of unsecured nuclear and other radioactive material persists; - effective border control measures help to detect illicit trafficking, although effective control is not uniformly implemented at all international border points; and - individuals and groups are prepared to engage in trafficking this material. A disturbing trend is trafficking in particularly sensitive regions of the world, such as in countries that were formerly a part of the former Soviet Union. In November 2010, Georgian officials seized four individuals allegedly trying to sell cesium-137, which though fairly common can be used to make a radiological dispersion device (RDD) or 'dirty bomb'. This closely followed a court case in Georgia involving Armenian nationals who had attempted to sell weapon-grade plutonium. More recently, in June 2011, Moldovan police arrested six individuals suspected of trafficking in uranium-235. In view of the problem, this paper considers whether an international convention specifically targeting illicit trafficking is needed or not. The paper does not go conceptually beyond the legal aspects of controlling and repressing illicit trafficking; rather, it will look at whether the existing

    In conventional PID scheme, the ensemble control performance may be unsatisfactory due to limited degrees of freedom under various kinds of uncertainty. To overcome this disadvantage, a novel PID control method that inherits the advantages of fuzzy PID control and the predictive functional control (PFC) is presented and further verified on the temperature model of a coke furnace. Based on the framework of PFC, the prediction of the future process behavior is first obtained using the current process input signal. Then, the fuzzy PID control based on the multi-step prediction is introduced to acquire the optimal control law. Finally, the case study on a temperature model of a coke furnace shows the effectiveness of the fuzzy PID control scheme when compared with conventional PID control and fuzzy self-adaptive PID control.

    2017-01-01

    Temporal network, whose topology evolves with time, is an important class of complex networks. Temporal trees of a temporal network describe the necessary edges sustaining the network as well as their active time points. By a switching controller which properly selects its location with time, temporal trees are used to improve the controllability of the network. Therefore, more nodes are controlled within the limited time. Several switching strategies to efficiently select the location of the controller are designed, which are verified with synthetic and empirical temporal networks to achieve better control performance.

    Frost, Susan A.; Taylor, Brian R.; Jutte, Christine V.; Burken, John J.; Trinh, Khanh V.; Bodson, Marc

    2010-01-01

    Conventional aircraft generally employ mixing algorithms or lookup tables to determine control surface deflections needed to achieve moments commanded by the flight control system. Control allocation is the problem of converting desired moments into control effector commands. Next generation aircraft may have many multipurpose, redundant control surfaces, adding considerable complexity to the control allocation problem. These issues can be addressed with optimal control allocation. Most optimal control allocation algorithms have control surface position and rate constraints. However, these constraints are insufficient to ensure that the aircraft's structural load limits will not be exceeded by commanded surface deflections. In this paper, a framework is proposed to enable a flight control system with optimal control allocation to incorporate real-time structural load feedback and structural load constraints. A proof of concept simulation that demonstrates the framework in a simulation of a generic transport aircraft is presented.

    The legal competency or capability to exercise rights is level of judgment and decision-making ability needed to manage one's own affairs and to sign official documents. With some exceptions, the person entitles this right in age of majority. It is acquired without legal procedures, however the annulment of legal capacity requires a juristic process. This resolution may not be final and could be revoked thorough the procedure of reverting legal capacity - fully or partially. Given the increasing number of persons with dementia, they are often subjects of legal expertise concerning their legal capacity. On the other part, emphasis on the civil rights of mentally ill also demands their maximal protection. Therefore such distinctive issue is approached with particular attention. The approach in determination of legal competency is more focused on gradation of it's particular aspects instead of existing dual concept: legally capable - legally incapable. The main assumption represents how person with dementia is legally capable and should enjoy all the rights, privileges and obligations as other citizens do. The aspects of legal competency for which person with dementia is going to be deprived, due to protection of one's rights and interests, are determined in legal procedure and then passed over to the guardian decided by court. Partial annulment of legal competency is measure applied when there is even one existing aspect of preserved legal capability (pension disposition, salary or pension disposition, ability of concluding contract, making testament, concluding marriage, divorce, choosing whereabouts, independent living, right to vote, right to decide course of treatment ect.). This measure is most often in favour of the patient and rarely for protection of other persons and their interests. Physicians are expected to precisely describe early dementia symptoms which may influence assessment of specific aspects involved in legal capacity (memory loss, impaired task

    The tightness of control procedures in the legal protection provided by jurisdiction against directives issued by the Federal Government - a problem of competence distribution between the Federal Constitutional Court and the Federal Administrative Court? The article examines questions of recourse to the competent court, problems concerning the admissibility of legal proceedings before the Federal Admininstrative Court, the competence of the Laender in performing administrative acts on behalf of the Federation, the effectiveness of legal protection and the relationship between the Laender and the Federation in terms of responsibility for constitutional rights. The legal protection offered by administrative law, against a directive of the Federal Government is wholly ineffective, as there is no legal position a Land could bring into play to defened itself against a directive leading to unlawful action. Inequites which thus occur can however be met via a dispute between the Federation and the Laender as provided by the constitution, as the content of a directive becomes relevant in attempts to exert influence on the competence issue. Ultimately the rulings of the Basic Law on competence serve to protect the citizen and the community against excesses. In this connection the constitutional rights in their capacity as negative competence rulings disqualify executive acts. (orig./HSCH) [de

    2013-01-01

    Structured Controllers for Uncertain Systems focuses on the development of easy-to-use design strategies for robust low-order or fixed-structure controllers (particularly the industrially ubiquitous PID controller). These strategies are based on a recently-developed stochastic optimization method termed the "Heuristic Kalman Algorithm" (HKA) the use of which results in a simplified methodology that enables the solution of the structured control problem without a profusion of user-defined parameters. An overview of the main stochastic methods employable in the context of continuous non-convex optimization problems is also provided and various optimization criteria for the design of a structured controller are considered; H∞, H2, and mixed H2/H∞ each merits a chapter to itself. Time-domain-performance specifications can be easily incorporated in the design. Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technolo...

    Full Text Available Due to the influence of nonlinearity and time-variation, it is difficult to establish an accurate model of a magnetorheological damping structure that adopts semiactive control. Fuzzy control is a relatively appropriate control method, but fuzzy control design is susceptible to human subjective experience, which will decrease the control effect. This paper proposes new fuzzy control rules based on a genetic algorithm (GA and particle swarm optimization (PSO and performs a numerical simulation for a three-layer reinforced concrete frame structure under conditions of an uncontrolled structure, fuzzy control, fuzzy control optimized by GA, fuzzy control optimized by PSO, and GA-optimized FLC control (GA-FLC proposed by Ali and Ramaswamy (2008. The results show that (1 the fitness values of the convergence of the two types of optimized fuzzy control are close. The speed of the convergence of the fuzzy control optimized by PSO is faster than that of the fuzzy control optimized by GA, but its running speed is slower. (2 Comparing the acceleration and displacement of the structure under the conditions of three different seismic waves, the effect of the optimized fuzzy control is better than that of the human experience fuzzy control and GA-FLC.

    Controlling complex networks is of vital importance in science and engineering. Meanwhile, local-world effect is an important ingredient which should be taken into consideration in the complete description of real-world complex systems. In this letter, structural controllability of a class of local-world networks is investigated. Through extensive numerical simulations, firstly, effects of local world size M and network size N on structural controllability are examined. For local-world networks with sparse topological configuration, compared to network size, local-world size can induce stronger influence on controllability, however, for dense networks, controllability is greatly affected by network size and local-world effect can be neglected. Secondly, relationships between controllability and topological properties are analyzed. Lastly, the robustness of local-world networks under targeted attacks regarding structural controllability is discussed. These results can help to deepen the understanding of structural complexity and connectivity patterns of complex systems. - Highlights: • Structural controllability of a class of local-world networks is investigated. • For sparse local-world networks, compared to network size, local-world size can bring stronger influence on controllability. • For dense networks, controllability is greatly affected by network size and the effect of local-world size can be neglected. • Structural controllability against targeted node attacks is discussed.

    The dynamic synthesis of gyroscopic structures consisting of point-connected substructures is investigated. The objective is to develop a mathematical model capable of an adequate simulation of the modal characteristics of a helicopter using a minimum number of degrees of freedom. The basic approach is to regard the helicopter structure as an assemblage of flexible substructures. The variational equations for the perturbed motion about certain equilibrium solutions are derived. The discretized variational equations can be conveniently exhibited in matrix form, and a great deal of information about the system modal characteristics can be extracted from the coefficient matrices. The derivation of the variational equations requires a monumental amount of algebraic operations. To automate this task a symbolic manipulation program on a digital computer is developed.

    The most important goal of the Environmental Law is to maximize the prevention approach. As so far, a scheme has been initiated since a few years to reach this objective: a legal environmental process with a lot of mechanisms whose the objective is to estimate the environmental impact of a project in order to control it. This legal environmental process including for example the Environmental Impact Assessment is more and more integrated in the environmental policies of the industrialized countries. It began in North America, first in the U.S.A. but also in Canada. A few years after, the countries of the Western Europe, particularly the European Unions, have introduced a similar legal process taking into account the specificities of these European countries. So if the goals of this legal environmental preventive approach are similar in North America and in Western Europe, the implementation is often different according to the legal, economic but also sociological structures of these two major regions. This Phd Thesis try to study the two major impacts of this legal evaluating process: it is implemented by the public authorities to reach with a best result a Sustainable Development. But also, it tries to combine the protection of the Environment and the utilisation of legal, economic and financial mechanisms of the Market to obtain a fair trade competition. (authors)

  7. Mediation and Legal Assistance

    2014-01-01

    Full Text Available The development of alternative dispute resolution procedures raises a number of new problems and questions for jurisprudence and legal practice. Many of these are closely related to the implementation of mediation procedures. Significant attention has been paid in the legal literature to the need for mediators’ legal education. Nowadays a professional lawyer usually performs the functions of a mediator. Nevertheless, in some countries the competence of mediators can be limited. In fact, such persons may be prohibited from providing any legal assistance to the parties. A direct prohibition of this kind exists in Russian legislation. To what degree is this prohibition realistic and reasonable? Different countries enjoy different approaches to the possibility of providing disputing parties with a mediator’s legal assistance in addressing issues requiring legal advice or in the drafting of legal documents. Different approaches to this issue have appeared for various reasons. The absence of consensus is caused by a contradiction between the principle of mediator neutrality in the conflict resolution process and the goals of dispute settlement in which a legally competent intermediary is involved. To ensure the effectiveness of the mediation process, legislators should seek out more flexible ways of regulating procedure. Mandatory regulation itself contradicts the spirit of ‘semi-formal’ alternative (extrajudicial methods for conflict resolution. As such, the presence of direct prohibitions or severe restrictions may not only become challenging in the performance of law but such peremptory norms can also make mediation unattractive and ineffective for some particular types of dispute, such as labor disputes. The principle of preserving a mediator’s neutrality is possible if exercised within the framework of a balanced approach to reasonable limits and discretionary rules for the provision of certain types of legal assistance to disputing

    Model uncertainty, if ignored, can seriously degrade the performance of an otherwise well-designed control system. If the level of this uncertainty is extreme, the system may even be driven to instability. In the context of structural control, performance degradation and instability imply excessive vibration or even structural failure. Robust control has typically been applied to the issue of model uncertainty through worst-case analyses. These traditional methods include the use of the structured singular value, as applied to the small gain condition, to provide estimates of controller robustness. However, this emphasis on the worst-case scenario has not allowed a probabilistic understanding of robust control. In this paper an attempt to view controller robustness as a probability measure is presented. The probability of failure due to parametric uncertainty is estimated using first-order reliability methods (FORM). It is demonstrated that this method can provide quite accurate results on the probability of failure of actively controlled structures. Moreover, a comparison of this method to a suitability modified structured singular value robustness analysis in a probabilistic framework is performed. It is shown that FORM is the superior analysis technique when applied to a controlled three degree-of-freedom structure. In addition, the robustness qualities of various active control design schemes such as LQR, H{sub 2}, H {sub oo}, and {mu}-synthesis is discussed in order to provide some design guidelines.

    Structural control for civil structures was born out of a need to provide safer and more efficient designs with the reality of limited resources. The purpose of structural control is to absorb and to reflect the energy introduced by dynamic loads such as winds, waves, earthquakes, and traffic. Today, the protection of civil structures from severe dynamic loading is typically achieved by allowing the structures to be damaged. Semi-active control devices, also called "smart" control devices, assume the positive aspects of both the passive and active control devices. A semi-active control strategy is similar to the active control strategy. Only here, the control actuator does not directly apply force to the structure, but instead it is used to control the properties of a passive energy device, a controllable passive damper. Semi-active control strategies can be used in many of the same civil applications as passive and active control. One method of operating smart cable dampers is in a purely passive capacity, supplying the dampers with constant optimal voltage. The advantages to this strategy are the relative simplicity of implementing the control strategy as compared to a smart or active control strategy and that the dampers are more easily optimally tuned in- place, eliminating the need to have passive dampers with unique optimal damping coefficients. This research investigated semi-active control of civil structures for natural hazard mitigation. The research has two components, the seismic protection of buildings and the mitigation of wind-induced vibration in structures. An ideal semi-active motion equation of a composite beam that consists of a cantilever beam bonded with a PZT patch using Hamilton's principle and Galerkin's method was treated. A series R-L and a parallel R-L shunt circuits are coupled into the motion equation respectively by means of the constitutive relation of piezoelectric material and Kirchhoff's law to control the beam vibration.

    Distillation columns can consume a large portion of energy in chemical industry processes. Integrated Petlyuk columns have been shown to improve energy efficiencies by between 20 and 40 per cent, and thermally coupled distillation columns can serve as an alternative to conventional distillation sequences in multicomponent mixture separation processes. Until recently, operational difficulties have limited the wider introduction of Petlyuk columns in industrial applications. Alternative Petlyuk-type schemes have now been developed to provide improved operation properties. This paper discussed, evaluated, and compared the theoretical control properties of 6 different Petlyuk schemes. Computations were performed using a singular value decomposition (SVD) technique in the frequency domain. Dynamic closed-loop responses for set point tracking, and disturbance rejections were derived in order to support each scheme's theoretical control properties. Results of the comparative evaluation demonstrated that reductions in the number of interconnections and the use of unidirectional flows impacted the dynamic properties of the schemes, and led to operational improvements in thermally coupled distillation sequences. It was concluded that Petyluk properties can be improved through the correction of the bidirectionality of interconnecting streams. 30 refs., 10 tabs., 9 figs.

    A homotopy approach involving multiobjective functions is developed to outline the methods that have evolved for the combined control-structure optimization of physical systems encountered in the technology of large space structures. A method to effect a timely consideration of the control performance prior to the finalization of the structural design involves integrating the control and structural design processes into a unified design methodology that combines the two optimization problems into a single formulation. This study uses the combined optimization problem as a family of weighted structural and control costs. Connections with vector optimizations are described; an analysis of the zero-set of required conditions is made, and a numerical example is given.

    1993-01-01

    It is the objective of this paper to present a model reduction technique developed for the integrated controls-structures design of flexible structures. Integrated controls-structures design problems are typically posed as nonlinear mathematical programming problems, where the design variables consist of both structural and control parameters. In the solution process, both structural and control design variables are constantly changing; therefore, the dynamic characteristics of the structure are also changing. This presents a problem in obtaining a reduced-order model for active control design and analysis which will be valid for all design points within the design space. In other words, the frequency and number of the significant modes of the structure (modes that should be included) may vary considerably throughout the design process. This is also true as the locations and/or masses of the sensors and actuators change. Moreover, since the number of design evaluations in the integrated design process could easily run into thousands, any feasible order-reduction method should not require model reduction analysis at every design iteration. In this paper a novel and efficient technique for model reduction in the integrated controls-structures design process, which addresses these issues, is presented.

    Full Text Available Relevance of the research is conditioned by the necessity to enhance the factory quality control of reinforced concrete structures based on integral assessment of their reliability. The current system of selective quality control of precast concrete structures does not provide reliability assurance of the whole lot of products. The present research aims to develop operational procedure and consider economic feasibility of automated quality control of precast RC structures. Quality control is performed each shift according to the developed software system based on probabilistic methods considering statistic variability of the controlled parameters. The critical criterion of operational integrity of structures is integral assessment of the reliability indicators. The following theoretical research methods were used in the study: probabilistic-statistical, methods of system and economic analysis. Validity of the obtained results and economic feasibility were proved by experimental studies including full-scale tests.

    In our previous paper dealing with multi-patterning, we proposed a new indicator to quantify the quality of final wafer pattern transfer, called interactive pattern fidelity error (IPFE). It detects patterning failures resulting from any source of variation in creating integrated patterns. IPFE is a function of overlay and edge placement error (EPE) of all layers comprising the final pattern (i.e. lower and upper layers). In this paper, we extend the use cases with Via in additional to the bridge case (Block on Spacer). We propose an IPFE budget and CD budget using simple geometric and statistical models with analysis of a variance (ANOVA). In addition, we validate the model with experimental data. From the experimental results, improvements in overlay, local-CDU (LCDU) of contact hole (CH) or pillar patterns (especially, stochastic pattern noise (SPN)) and pitch walking are all critical to meet budget requirements. We also provide a special note about the importance of the line length used in analyzing LWR. We find that IPFE and CD budget requirements are consistent to the table of the ITRS's technical requirement. Therefore the IPFE concept can be adopted for a variety of integrated structures comprising digital logic circuits. Finally, we suggest how to use IPFE for yield management and optimization requirements for each process.

  19. Active structural control with stable fuzzy PID techniques

    CERN Document Server

    Yu, Wen

    2016-01-01

    This book presents a detailed discussion of intelligent techniques to measure the displacement of buildings when they are subjected to vibration. It shows how these techniques are used to control active devices that can reduce vibration 60–80% more effectively than widely used passive anti-seismic systems. After introducing various structural control devices and building-modeling and active structural control methods, the authors propose offset cancellation and high-pass filtering techniques to solve some common problems of building-displacement measurement using accelerometers. The most popular control algorithms in industrial settings, PD/PID controllers, are then analyzed and then combined with fuzzy compensation. The stability of this combination is proven with standard weight-training algorithms. These conditions provide explicit methods for selecting PD/PID controllers. Finally, fuzzy-logic and sliding-mode control are applied to the control of wind-induced vibration. The methods described are support...

  20. Represenation of process state, structure and control

    Supervisory control is essentially a decision-making activity where, among other things, the dm has to maneuver within a complex problem space which reflects key dimensions and attributes of the object system (power plant ...). Of considerable importance therefore is the representation for the dm of this problem space comprising at the one end the target demands, goals, constraints and, at the other, the resources available for meeting the assigned goals - and all of this in pace with the dynamic event-driven environment which characterizes the types of systems of interest. Previous work has identified the advantages of utilizing the two-dimensional means-ends/part-whole space as a basic ingredient in a system representation. This paper associates more detailed representational requirements at the various levels of the means-ends axis with the activities of state identification and diagnosis. In addition, some examples of display formats which attempt to incorporate the outlined representational principles within the context of a PWR plant are discussed. (authors)

    Full Text Available There is no idea, business or company, private or public control, which does not require an appropriate legal strategy to be implemented as efficiently as possible. Therefore, there is no way actually know the areas of law that are directly related to the business organization, without analysis of the planning logic and implementation of ideas generally used by companies. More than that, the combination of modeling and business planning is essential, with appropriate legal and related strategic planning of business objectives. So it’s the need and the importance of developing a Legal Business Model that can be used in combination with Canvas.

    Full Text Available The paper aims at expanding the theoretical basis of discourse analysis by involving the theory of fields by P. Bourdieu who says that there is a social genesis of perception and thinking patterns and actions (habitus, on the one hand, and social structures and fields, on the other one. The speaking subject is influenced by objective relations of forces typical for a certain field – a social area with specific social relations, means and purposes. All agents of the legal field are able to use polysemy of legal formulas, tend to use the elasticity of the law, existing ambiguity and gaps in their own interests. Using expert knowledge as a manipulative resource, agents of the legal field enforce their own views on lay people. Social differences between agents of the legal field (legal experts and their clients (lay people are due to their struggle for monopoly which means increase in distance between formally specified legal rules and na−ve intuitive concepts of legal phenomena. Individuals who are prone to behavior complying with a certain matrix of social actions are a typical feature of legal discourse practices. When interacting with lay people, experts, whose actions comply with specific institutional status, control their discursive behavior.

  7. Nonlinear vibration with control for flexible and adaptive structures

    2015-01-01

    This book provides a comprehensive discussion of nonlinear multi-modal structural vibration problems, and shows how vibration suppression can be applied to such systems by considering a sample set of relevant control techniques. It covers the basic principles of nonlinear vibrations that occur in flexible and/or adaptive structures, with an emphasis on engineering analysis and relevant control techniques. Understanding nonlinear vibrations is becoming increasingly important in a range of engineering applications, particularly in the design of flexible structures such as aircraft, satellites, bridges, and sports stadia. There is an increasing trend towards lighter structures, with increased slenderness, often made of new composite materials and requiring some form of deployment and/or active vibration control. There are also applications in the areas of robotics, mechatronics, micro electrical mechanical systems, non-destructive testing and related disciplines such as structural health monitoring.

    The Control/Structure Interaction Program is a technology development program for spacecraft that exhibit interactions between the control system and structural dynamics. The program objectives include development and verification of new design concepts - such as active structure - and new tools - such as combined structure and control optimization algorithm - and their verification in ground and possibly flight test. A focus mission spacecraft was designed based upon a space interferometer and is the basis for design of the ground test article. The ground test bed objectives include verification of the spacecraft design concepts, the active structure elements and certain design tools such as the new combined structures and controls optimization tool. In anticipation of CSI technology flight experiments, the test bed control electronics must emulate the computation capacity and control architectures of space qualifiable systems as well as the command and control networks that will be used to connect investigators with the flight experiment hardware. The Test Bed facility electronics were functionally partitioned into three units: a laboratory data acquisition system for structural parameter identification and performance verification; an experiment supervisory computer to oversee the experiment, monitor the environmental parameters and perform data logging; and a multilevel real-time control computing system. The design of the Test Bed electronics is presented along with hardware and software component descriptions. The system should break new ground in experimental control electronics and is of interest to anyone working in the verification of control concepts for large structures.

  15. Passive Control of Flexible Structures by Confinement of Vibrations

    Directory of Open Access Journals (Sweden)

    M. Ouled Chtiba

    2007-01-01

    Full Text Available We propose a two-step strategy for the design of passive controllers for the simultaneous confinement and suppression of vibrations (SCSV in mechanical structures. Once the sensitive and insensitive elements of these structures are identified, the first design step synthesizes an active control law, which is referred to as the reference control law (RCL, for the SCSV. We show that the problem of SCSV can be formulated as an LQR-optimal control problem through which the maximum amplitudes, associated with the control input and the displacements of the sensitive and insensitive parts, can be regulated. In the second design step, a transformation technique that yields an equivalent passive controller is used. Such a technique uses the square root of sum of squares method to approximate an equivalent passive controller while maximizing the effects of springs and dampers characterizing passive elements that are added to the original structure. The viability of the proposed control design is illustrated using a three-DOF mechanical system subject to an excitation. It is assumed that all of the masses are sensitive to the excitation, and thus the vibratory energy must be confined in the added passive elements (insensitive parts. We show that the vibration amplitudes associated with the sensitive masses are attenuated at fast rate at the expense of slowing down the convergence of the passive elements to their steady states. It is also demonstrated that a combination of the RCL and the equivalent passive control strategy leads to similar structural performance.

  16. Control and large deformations of marginal disordered structures

    Science.gov (United States)

    Murugan, Arvind; Pinson, Matthew; Chen, Elizabeth

    Designed deformations, such as origami patterns, provide a way to make easily controlled mechanical metamaterials with tailored responses to external forces. We focus on an often overlooked regime of origami - non-linear deformations of large disordered origami patterns with no symmetries. We find that practical questions of control in origami have counterintuitive answers, because of intimate connections to spin glasses and neural networks. For example, 1 degree of freedom origami structures are actually difficult to control about the flat state with a single actuator; the actuator is thrown off by an exponential number of `red herring' zero modes for small deformations, all but one of which disappear at larger deformations. Conversely, structures with multiple programmed motions are much easier to control than expected - in fact, they are as easy to control as a dedicated single-motion structure if the number of programmed motions is below a threshold (`memory capacity').

    2012-01-01

    In this paper a resonant control technique, called negative derivative feedback (NDF), for structural vibration control is presented. Resonant control is a class of control logics, based on the modal approach, which calculates the control action through a dynamic compensator in order to achieve a damping increase on a certain number of system modes. The NDF compensator is designed to work as a band-pass filter, cutting off the control action far from the natural frequencies associated with the controlled modes and reducing the so-called spillover effect. In the paper the proposed control logic is compared both theoretically and experimentally with the most common state-of-the-art resonant control techniques. (paper)

  4. Innovative Legal Approaches to Address Obesity

    Pomeranz, Jennifer L; Teret, Stephen P; Sugarman, Stephen D; Rutkow, Lainie; Brownell, Kelly D

    2009-01-01

    Context: The law is a powerful public health tool with considerable potential to address the obesity issue. Scientific advances, gaps in the current regulatory environment, and new ways of conceptualizing rights and responsibilities offer a foundation for legal innovation. Methods: This article connects developments in public health and nutrition with legal advances to define promising avenues for preventing obesity through the application of the law. Findings: Two sets of approaches are defined: (1) direct application of the law to factors known to contribute to obesity and (2) original and innovative legal solutions that address the weak regulatory stance of government and the ineffectiveness of existing policies used to control obesity. Specific legal strategies are discussed for limiting children's food marketing, confronting the potential addictive properties of food, compelling industry speech, increasing government speech, regulating conduct, using tort litigation, applying nuisance law as a litigation strategy, and considering performance-based regulation as an alternative to typical regulatory actions. Finally, preemption is an overriding issue and can play both a facilitative and a hindering role in obesity policy. Conclusions: Legal solutions are immediately available to the government to address obesity and should be considered at the federal, state, and local levels. New and innovative legal solutions represent opportunities to take the law in creative directions and to link legal, nutrition, and public health communities in constructive ways. PMID:19298420

    Controlling the structure formation of gold nanoparticle aggregates is a promising approach towards novel applications in many fields, ranging from (bio)sensing to (bio)imaging to medical diagnostics and therapeutics. To steer structure formation, the DNA-DNA interactions of DNA strands that are coated on the surface of the particles have become a valuable tool to achieve precise control over the interparticle potentials. In equilibrium approaches, this technique is commonly used to study particle crystallization and ligand binding. However, regulating the structural growth processes from the nano- to the micro- and mesoscale remains elusive. Here, we show that the non-equilibrium structure formation of gold nanoparticles can be stirred in a binary heterocoagulation process to generate nanoparticle clusters of different sizes. The gold nanoparticles are coated with sticky single stranded DNA and mixed at different stoichiometries and sizes. This not only allows for structural control but also yields access to the optical properties of the nanoparticle suspensions. As a result, we were able to reliably control the kinetic structure formation process to produce cluster sizes between tens of nanometers up to micrometers. Consequently, the intricate optical properties of the gold nanoparticles could be utilized to control the maximum of the nanoparticle suspension extinction spectra between 525 nm and 600 nm. © 2017 Wiley-VCH Verlag GmbH & Co.

  16. Legal nature of affatomia

    Directory of Open Access Journals (Sweden)

    Stanković Miloš

    2015-01-01

    Full Text Available In Salian and Ripuarian Code affatomia represented a bilateral legal transaction that was aimed at changing of the scoped of heirs determined by the customs, at least insofar being applied in the absence of biological descendants only. However, almost all further similarities in the field cease at this point. The form for using affatomia with Ripuarian Franks was much simpler than the one with the Salian Franks. Unlike the Salian Franks, affatomia could by all odds be used by Ripuarian Franks spouses in determining each other for a heir. Legal nature of the Salian Franks affatomia is most similar to the mancipatio familiae type of will in the Roman law (which does not mean it emerged from this law, while its form in the Ripuarian Code is much closer to testamentary adoption. As with Ripuarian Franks, affatomia seems to have definitely produced legal effects only after the death of the disposant, while its legal effects with the Salian Code performed inter vivos. Contemporary authors are trying to designate the legal nature of legal affairs from the early development of human and legal civilization through modern institutes that represent the completion of their evolutionary path. Taking the inheritance contract of the German or Swiss law, or the future assets donation of the French law, for example, and then comparing them to affatomia and thinx is an anachronism. This is evident by the fact that the legal nature of these ancient Germanic institutes can not be viewed unilaterally, but always through a combination of those institutes which we know today as adoption, gift or mixed donation with retention of different modalities for the transferor or the testator (usually usufruct. In this sense, if we are looking for a inheritance agreement in the Middle Ages, the contract in which a person determines other person for his/her universal or singular successor in the modern sense, we will certainly not find one. However, if within this institute we

    Science.gov (United States)

    Poh, S.; Baz, A.

    1990-01-01

    The feasibility of a new Modal Positive Position Feedback (MPPF) strategy in controlling the vibration of a complex flexible structure using a single piezo-electric active structural member is demonstrated. The control strategy generates its control forces by manipulating only the modal position signals of the structure to provide a damping action to undamped modes. This is in contrast to conventional modal controllers that rely in their operation on negative feedback of both the modal position and velocity. The proposed strategy is very simple to design and implement as it designs the controller at the uncoupled modal level and utilizes simple first order filters to achieve the Positive Position Feedback effect. The performance of the new strategy is enhanced by augmenting it with a time sharing strategy to share a small number of actuators between larger number of modes. The effectiveness of the new strategy is validated experimentally on a flexible box-type structure that has four bays and its first two bending modes are 2.015 and 6.535 Hz, respectively. A single piezo-electric actuator is utilized as an active structural member to control several transverse bending modes of the structure. The performance of the active control system is determined in the time and the frequency domains. The results are compared with those obtained when using the Independent Modal Space Control (IMSC) of Meirovitch. The experimental results suggest the potential of the proposed strategy as a viable means for controlling the vibration of large flexible structures in real time.

    This paper presents health monitoring of welded structures using acceleration time response data. Residual errors are extracted from the measured acceleration time response data using an auto-regressive model. Damage identification is done by monitoring the residual errors using Shewhart and exponentially weighted moving average control charts. The applicability of the proposed method is tested with the welded structure model. Five damage levels are investigated and the damage is introduced by cutting a slot in the weld using an electrical discharge machine. Acceleration time response data are collected using piezoelectric sensors for all damage levels. The results show that both Shewhart and exponentially weighted moving average control charts are capable of identifying the presence of damage in the welded structure model under consideration. Exponentially weighted moving average control charts are more sensitive in damage identification than Shewhart control charts.

    Since the pioneering work of Zadeh and Mamdani and Assilian, fuzzy logic control has emerged as one of the most active and fruitful research areas. The applications of fuzzy logic control can be found in many fields such as control of stream generators, automatic train operation systems, elevator control, nuclear reactor control, automobile transmission control, etc. In this paper, two new structures of hierarchical fuzzy rule-based controller are proposed to reduce the number of rules in a complete rule set of a controller. In one approach, the overall system is split into sub-systems which are treated independently in parallel. A coordinator is then used to take into account the interactions. This is done via an iterating information exchange between the lower level and the coordinator level. From the point of view of information used, this structure is very similar to central structure in that the coordinator can have at least in principle, all the information that the local controllers have.

    This paper is concerned with the active vibration control of a grid structure equipped with piezoceramic sensors and actuators. The grid structure is a replica of the solar panel commonly mounted on satellites, which contains complex natural mode shapes. The multiinput and multioutput positive position feedback (PPF) controller is considered as an active vibration controller for the grid structure. A new concept, the block-inverse technique, is proposed to cope with more modes than the number of actuators and sensors. This study also deals with the stability and the spillover effect associated with the application of the multiinput multioutput PPF controller based on the block-inverse technique. It was found that the theories developed in this study are capable of predicting the control system characteristics and its performance. The new multiinput multioutput PPF controller was applied to the test structure using a digital signal processor and its efficacy was verified by experiments.

  2. The latitude of logic in legal hermeneutics

    Full Text Available Legal hermeneutics (the interpretation of law] has always taken a highly significant place in general hermeneutics. The interpretation of laws involves an intricate task of determining the real meaning or rationale of legal norms. Considering the complexity of this goal, the most frequent classification of legal hermeneutics is based on the interpretation instruments. In traditional theory, the most widely recognized instruments for the interpretation of legal norms are language, logic, legal system, history and purpose of a legal norm. Under the influence of general analytic philosophy, the particular interest in language as the basic instrument for the interpretation of law may be found in mid-20th century. The interest in the language of law is closely related to the study of legal logic and legal argumentation. In theory, there is no dispute about the logical interpretation in a narrow sense which is based on drawing true conclusions by applying the basic rule of formal reasoning. Yet, it has given a head start to argumentation as 'a problem-based reasoning skill' which provides answers to the questions raised in contentious cases. Argumentation is closely associated with the dialectic method of reasoning (which has been widely recognized since the Ancient Greece], where conclusions are based on probable premises. One of the most significant goals of the argumentation theory is to locate the sources or common grounds for developing arguments; these basic argumentative patterns are generally known as 'topoi' or 'loci, sedes argumentorum'. On the other hand, 'topica' is part of rhetoric art dealing with the theoretical explanation of the basic argumentative patterns (topoi] and how they are structured, including the location of new topoi and arguments. The most significant proponents of the topical reasoning are Chaïm Perelman and Theodor Viehweg. Perelman relates topical reasoning to judicial reasoning and considers that specific legal topoi

    The liberalisation and international integration of electricity markets have led to a dramatic increase in the complexity of the electricity sector. Rather than hierarchical control, it is the legal framework (rules of the game that determines the behaviour of actors such as power generators, traders and network operators). Because of the unusual technical and economic characteristics of electricity markets, their performance is very sensitive to the formulation of the legal framework. Still, a structured approach to formulating the legal framework has not yet been developed. This book meets this demand. Many questions need to be answered in the design of a legal framework for the electricity industry and often they are interdependent. This study proposes a design method for the analysis and design of the legal organisation of a technically complex sector such as the electricity industry. The method takes into account the relevant policy goals, legal constraints and technical characteristics. While the method is developed for electricity markets, it can be applied to other technically complex infrastructures as well. The proposed method is applied to several critical cases, such as the security of electricity supply, operational security in large networks, congestion management and the question how to deal with merchant transmission investment. In addition to validating the proposed method, these case studies offer a wealth of practical information about the policy choices for restructuring the electricity industry. This makes this book a rich resource for anyone interested in the design of electricity markets

    One of the advantages of anisotropic soft materials is that their structures and, consequently, their properties can be controlled by moderate external fields. Whereas the control of materials with uniform orientational order is straightforward, manipulation of systems with complex orientational order is challenging. We show that a variety of structures of an interesting liquid material, which combine chiral orientational order with ferromagnetic one, can be controlled by a combination of small magnetic and electric fields. In the suspensions of magnetic nanoplatelets in chiral nematic liquid crystals, the platelet's magnetic moments orient along the orientation of the liquid crystal and, consequently, the material exhibits linear response to small magnetic fields. In the absence of external fields, orientations of the liquid crystal and magnetization have wound structure, which can be either homogeneously helical, disordered, or ordered in complex patterns, depending on the boundary condition at the surfaces and the history of the sample. We demonstrate that by using different combinations of small magnetic and electric fields, it is possible to control reversibly the formation of the structures in a layer of the material. In such a way, different periodic structures can be explored and some of them may be suitable for photonic applications. The material is also a convenient model system to study chiral magnetic structures, because it is a unique liquid analog of a solid helimagnet.

    2015-01-01

    In this paper we aim to develop a controller that allows a robot to traverse an structured environment. The approach we use is to decompose the environment into simple sub-environments that we use as basis for evolving the controller. Specifically, we decompose a narrow corridor environment...... into four different sub-environments and evolve controllers that generalize to traverse two larger environments composed of the sub-environments. We also study two strategies for presenting the sub-environments to the evolutionary algorithm: all sub-environments at the same time and in sequence. Results...... show that by using a sequence the evolutionary algorithm can find a controller that performs well in all sub-environments more consistently than when presenting all sub-environments together. We conclude that environment decomposition is an useful approach for evolving controllers for structured...

    2017-01-01

    What can we learn about controlling a system solely from its underlying network structure? Here we adapt a recently developed framework for control of networks governed by a broad class of nonlinear dynamics that includes the major dynamic models of biological, technological, and social processes. This feedback-based framework provides realizable node overrides that steer a system toward any of its natural long-term dynamic behaviors, regardless of the specific functional forms and system parameters. We use this framework on several real networks, identify the topological characteristics that underlie the predicted node overrides, and compare its predictions to those of structural controllability in control theory. Finally, we demonstrate this framework’s applicability in dynamic models of gene regulatory networks and identify nodes whose override is necessary for control in the general case but not in specific model instances.

    The dynamics and control of flexible aerospace structures exercises many of the engineering disciplines. In recent years there has been considerable research in the developing and tailoring of control system design techniques for these structures. This problem involves designing a control system for a multi-input, multi-output (MIMO) system that satisfies various performance criteria, such as vibration suppression, disturbance and noise rejection, attitude control and slewing control. Considerable progress has been made and demonstrated in control system design techniques for these structures. The key to designing control systems for these structures that meet stringent performance requirements is an accurate model. It has become apparent that theoretically and finite-element generated models do not provide the needed accuracy; almost all successful demonstrations of control system design techniques have involved using test results for fine-tuning a model or for extracting a model using system ID techniques. This paper describes past and ongoing efforts at Ohio University and NASA MSFC to design controllers using 'data models.' The basic philosophy of this approach is to start with a stabilizing controller and frequency response data that describes the plant; then, iteratively vary the free parameters of the controller so that performance measures become closer to satisfying design specifications. The frequency response data can be either experimentally derived or analytically derived. One 'design-with-data' algorithm presented in this paper is called the Compensator Improvement Program (CIP). The current CIP designs controllers for MIMO systems so that classical gain, phase, and attenuation margins are achieved. The center-piece of the CIP algorithm is the constraint improvement technique which is used to calculate a parameter change vector that guarantees an improvement in all unsatisfied, feasible performance metrics from iteration to iteration.

    Takács, Gergely

    2012-01-01

    Real-time model predictive controller (MPC) implementation in active vibration control (AVC) is often rendered difficult by fast sampling speeds and extensive actuator-deformation asymmetry. If the control of lightly damped mechanical structures is assumed, the region of attraction containing the set of allowable initial conditions requires a large prediction horizon, making the already computationally demanding on-line process even more complex. Model Predictive Vibration Control provides insight into the predictive control of lightly damped vibrating structures by exploring computationally efficient algorithms which are capable of low frequency vibration control with guaranteed stability and constraint feasibility. In addition to a theoretical primer on active vibration damping and model predictive control, Model Predictive Vibration Control provides a guide through the necessary steps in understanding the founding ideas of predictive control applied in AVC such as: ·         the implementation of ...

    1999-01-01

    The paper deals with the unification of the existing linear control algorithms in order to facilitate their transfer to the engineering students and to industry's engineers. The resulting control algorithm is the Global Predictive Control (GlobPC), which is now taught at the graduate and continuing education levels. GlobPC is based on an internal model framework where three independent control criteria are minimized: one for tracking, one for regulation and one for feedforward. This structure allows to obtain desired tracking, regulation and feedforward behaviors in an optimal way while keeping them perfectly separated. It also cleanly separates the deterministic and stochastic predictions of the process model output. (author)

  12. Deformation compatibility control for engineering structures methods and applications

    CERN Document Server

    Zhu, Hanhua; Chen, Mengchong; Deng, Jianliang

    2017-01-01

    This book presents essential methods of deformation compatibility control, and explicitly addresses the implied conditions on the methods’ deformation compatibility. Consequently, these conditions can be considered in engineering structure design, while the conditions on stable equilibrium can be taken into account in the design method. Thus, the designed deformation and the actual deformation of the respective structure are approximately identical, guaranteeing both the flexibility of the construction material in force transmission and the equilibrium of force in the structure. Though equilibrium theory in engineering structures has been extensively studied, there has been comparatively little research on compatibility. In the limited researches available, the topics are primarily the theories and assumptions on the deformation compatibility, while few systematic works focus on the mechanical theoretical principles and methods of deformation compatibility control. As such, the flexibility of the constructi...

  13. Discrimination of legal entities: Phenomenological characteristics and legal protection

    Full Text Available Their social nature encourages people to associate and jointly achieve the goals that they would not be able to achieve individually. Legal entities are created as one of the legal modalities of that association, as separate entities that have their own legal personality independent of the subjectivity of their members. Legal entities are holders of some human rights, depending on the nature of the right, including the right to non-discrimination. All mechanisms envisaged for legal protection against discrimination in the national legislation are available to legal persons. On the other hand, the situation is quite different in terms of access to international forums competent to deal with cases of discrimination. Legal entities do not have access to some international forums, while they may have access to others under the same conditions prescribed for natural persons. Legal entities may be exposed to various forms of direct and indirect discrimination both in the private and in the public sphere of social relations. Phenomenological characteristics of discrimination against legal persons are not substantially different from discrimination against individuals. There are no significant differences regarding the application of discrimination test in cases of discrimination of legal entities as compared to the use of this test in cases involving discrimination of natural persons or groups of persons. Legal entities may be discriminated against on the basis of characteristics of their legal personality, such as those which are objective elements of the legal entity and part of its legal identity. Discrimination of legal entities may be based on personal characteristics of its members (i.e. people who make a personal essence of a legal entity because their characteristics can be 'transferred' to the legal entity and become part of its identity. Legal entities should also be protected from this special form of transferred (associative discrimination.

    The objective of the research has been to study the design of adaptive/learning control systems for the control of large flexible structures. In the first activity an adaptive/learning control methodology for flexible space structures was investigated. The approach was based on using a modal model of the flexible structure dynamics and an output-error identification scheme to identify modal parameters. In the second activity, a least-squares identification scheme was proposed for estimating both modal parameters and modal-to-actuator and modal-to-sensor shape functions. The technique was applied to experimental data obtained from the NASA Langley beam experiment. In the third activity, a separable nonlinear least-squares approach was developed for estimating the number of excited modes, shape functions, modal parameters, and modal amplitude and velocity time functions for a flexible structure. In the final research activity, a dual-adaptive control strategy was developed for regulating the modal dynamics and identifying modal parameters of a flexible structure. A min-max approach was used for finding an input to provide modal parameter identification while not exceeding reasonable bounds on modal displacement.

    Noise abatement is a problem of technology, medicine, law, and education. In the technical field, the problem of avoiding hazards is the primary one. In respect of encroachment upon neighbours mutual regard should be the foremost consideration. From the legal angle, a distinction is made between protection of the individial-above all under the provisions of the German Civil Code (Bürgerliches Gesetzbuch)-and of the community-under the provisions of criminal law and administrative law. Future legislation will have to concentrate increasingly upon governmental control measures especially with a view to prevention, instead of the issue of protection of the individual.

    2012-01-01

    This paper deals with structured control of linear parameter varying systems (LPV) with application to wind turbines. Instead of attempting to reduce the problem to linear matrix inequalities (LMI), we propose to design the controllers via an LMI-based iterative algorithm. The proposed algorithm...... can synthesize structured controllers like decentralized, static output and reduced order output feedback for discrete-time LPV systems. Based on a coordinate decent, it relies on a sufficient matrix inequality condition extended with slack variables to an upper bound on the induced L2-norm...... of the closed-loop system. Algorithms for the computation of feasible as well as optimal controllers are presented. The general case where no restrictions are imposed on the parameter dependence is treated here due to its suitability for modeling wind turbines. A comprehensive numerical example of a gain...

    1990-01-01

    Structural finite element models are often too large to be used in the design and analysis of control systems. Model reduction techniques must be applied to reduce the structural model to manageable size. In the past, engineers either performed the model order reduction by hand or used distinct computer programs to retrieve the data, to perform the significance analysis and to reduce the order of the model. To expedite this process, the latest version of INCA has been expanded to include an interactive graphical structural mode significance and model order reduction capability.

    With progress of technology in recent years, gigantism and complication such as high-rise buildings, nuclear reactors and so on have brought about new problems. Particularly, the safety and the reliability for damages in abnormal situations have become more important. Intelligent control systems which can judge whether the situation is normal or abnormal at real time and cope with these situations suitably are demanded. In this study, Cubic Neural Network (CNN) is adopted, which consists of the controllers possessing cubically some levels of information abstracting. In addition to the usual quantitative control, the qualitative control is used for the abnormal situations. And, by selecting a suitable controller, CNN can cope with the abnormal situation. In order to confirm the effectiveness of this system, the structural vibration control problems with sensory failure and elasto-plastic response are dealt with. As a result of simulations, it was demonstrated that CNN can cope with unexpected abnormal situations which are not considered in learning. (author)

Additionally, an actuation interface has recently been added to the sensing unit design to allow for direct operation of structural actuators. With a computational core capable of real-time data processing, the data acquisition and actuation interfaces can be coupled through discrete-time feedback control loops implemented in software. Looking to the future, this intelligent monitoring infrastructure can possibly tune a structural control system in real-time after early warning of a pending seismic disturbance has been communicated to the wireless sensor network.

    One disadvantage of the rapid advances in modern dentistry is that treatment options have never been more varied or confusing. Compounded by a more educated population greatly assisted by online information in an increasingly litigious society, a major concern in recent times is increased litigation against health practitioners. The manner in which courts handle disputes is ambiguous and what is considered fair or just may not be reflected in the judicial process. Although legal decisions in Australia follow a doctrine of precedent, the law is not static and is often reflected by community sentiment. In medical litigation, this has seen the rejection of the Bolam principle with a preference towards greater patient rights. Recent court decisions may change the practice of dentistry and it is important that the clinician is not caught unaware. The aim of this article is to discuss legal issues that are pertinent to the practice of modern dentistry through an analysis of legal cases that have shaped health law. Through these discussions, the importance of continuing professional development, professional association and informed consent will be realized as a means to limit the legal complications of dental practice. © 2014 Australian Dental Association.

    International Nuclear Information System (INIS)

    Samarakoon, Samindi M.K.; Ratnayake, R.M. Chandima

    2015-01-01

    Structural integrity control is vital for existing ageing as well as newly built offshore and onshore structures. Structural integrity control becomes highly sensitive to interventions under a potential loss of structural integrity when it comes to offshore oil and gas production and process facilities. This is mainly due to the inherent constraints present in carrying out engineering work in the offshore atmosphere. It has been further exacerbated by the ageing offshore structures and the necessity of carrying out life extension toward the end of their design service lives. Local and international regulations demand the implementation of appropriate strengthening, modification and repair plans when significant changes in the structural integrity are revealed. In this context, strengthening, modification and repair techniques such as welding, member removal/reduction of loading, mechanical clamping and grouted repairs play a vital role. This manuscript presents an approach for prioritizing the strengthening, modification and repair techniques using a multi-criteria analysis approach. An analytic hierarchy process has been selected for the analysis via an illustrative case. It also provides a comprehensive overview of currently existing; strengthening, modification and repair techniques and their comparative pros and cons. - Highlights: • Structural integrity control (SIC) of ageing and intact offshore structures. • Strengthening, modification and/or repair (SMR) techniques have been explained. • Application of multi-criteria analysis conserving SI has been illustrated. • SMR techniques prioritization and sensitivity analysis has been performed

    2013-01-01

    Full Text Available The control system may lose the performance to suppress the structural vibration due to the faults in sensors or actuators. This paper designs the filter to perform the fault detection and isolation (FDI and then reforms the control strategy to achieve the fault tolerant control (FTC. The dynamic equation of the structure with active mass damper (AMD is first formulated. Then, an estimated system is built to transform the FDI filter design problem to the static gain optimization problem. The gain is designed to minimize the gap between the estimated system and the practical system, which can be calculated by linear matrix inequality (LMI approach. The FDI filter is finally used to isolate the sensor faults and reform the FTC strategy. The efficiency of FDI and FTC is validated by the numerical simulation of a three-story structure with AMD system with the consideration of sensor faults. The results show that the proposed FDI filter can detect the sensor faults and FTC controller can effectively tolerate the faults and suppress the structural vibration.

  3. A new fuzzy sliding mode controller for vibration control systems using integrated-structure smart dampers

    Dzung Nguyen, Sy; Kim, Wanho; Park, Jhinha; Choi, Seung-Bok

    2017-04-01

    Vibration control systems using smart dampers (SmDs) such as magnetorheological and electrorheological dampers (MRD and ERD), which are classified as the integrated structure-SmD control systems (ISSmDCSs), have been actively researched and widely used. This work proposes a new controller for a class of ISSmDCSs in which high accuracy of SmD models as well as increment of control ability to deal with uncertainty and time delay are to be expected. In order to achieve this goal, two formualtion steps are required; a non-parametric SmD model based on an adaptive neuro-fuzzy inference system (ANFIS) and a novel fuzzy sliding mode controller (FSMC) which can weaken the model error of the ISSmDCSs and hence provide enhanced vibration control performances. As for the formulation of the proposed controller, first, an ANFIS controller is desgned to identify SmDs using the improved control algorithm named improved establishing neuro-fuzzy system (establishing neuro-fuzzy system). Second, a new control law for the FSMC is designed via Lyapunov stability analysis. An application to a semi-active MRD vehicle suspension system is then undertaken to illustrate and evaluate the effectiveness of the proposed control method. It is demonstrated through an experimental realization that the FSMC proposed in this work shows superior vibration control performance of the vehicle suspension compared to other surveyed controller which have similar structures to the FSMC, such as fuzzy logic and sliding mode control.

  5. An Efficient Modal Control Strategy for the Active Vibration Control of a Truss Structure

    Directory of Open Access Journals (Sweden)

    Ricardo Carvalhal

    2007-01-01

    Full Text Available In this paper an efficient modal control strategy is described for the active vibration control of a truss structure. In this approach, a feedback force is applied to each mode to be controlled according to a weighting factor that is determined by assessing how much each mode is excited by the primary source. The strategy is effective provided that the primary source is at a fixed position on the structure, and that the source is stationary in the statistical sense. To test the effectiveness of the control strategy it is compared with an alternative, established approach namely, Independent Modal Space Control (IMSC. Numerical simulations show that with the new strategy it is possible to significantly reduce the control effort required, with a minimal reduction in control performance.

    The successful economy in a country can be measured by the number of commercializing intellectual property rights (IPR). To pursue IPR growth, triple helix component becomes a backbone to weave academia, business and government to collaborate with each other. Generally, collaborations move from their common interest, but within triple helix the collaboration can be run structurally and sustain. Depart from the arguments; the question arises: How is the condition of Indonesia Innovation System? Through legal approach, this paper will explain current legal condition and legal structure of the Indonesian innovation system. The reason to review the law is to relate with the government’s target to create 1000 digital start-ups alike as in Silicon Valley level size. Therefore, legal framework review becomes useful to explain the condition of the law as a supporting system. In this sense, the legal prescription can be generated to confirm Indonesian laws, whether supported the national innovation system or conversely. Within law perspective, Indonesian government categorizes the innovative industry as a creative industry. However, there is still no resolute concept to follow. Therefore, some of law adjustment is needed to support the government’s plan to pursue commercialized innovation.

  7. Crisis Communication in Public Health Emergencies: The Limits of 'Legal Control' and the Risks for Harmful Outcomes in a Digital Age.

    Communication by public authorities during a crisis situation is an essential and indispensable part of any response to a situation that may threaten both life and property. In the online connected world possibilities for such communication have grown further, in particular with the opportunity that social media presents. As a consequence, communication strategies have become a key plank of responses to crises ranging from epidemics to terrorism to natural disaster. Such strategies involve a range of innovative practices on social media. Whilst being able to bring about positive effects, they can also bring about a range of harmful unintended side effects. This include economic harms produced by incorrect information and a range of social harms that can be fuelled by myths and rumours, worsening negative phenomena such as stigmatisation and discrimination. Given the potential for such harms, one might expect that affected or potentially affected individuals would be able to challenge such measures before courts or administrative tribunals. As this paper demonstrates however this is not the case. More often than not seemingly applicable legal approaches are unlikely to be able to engage such methods. This is often because such measures represent activities that are purely expressive in nature and therefore not capable of imposing any binding legal or corporeal changes on individuals. Whilst some forms of soft law may pose requirements for public officials involved in such activities (e.g. codes of conduct or of professional ethics), they are not likely to offer potentially harmed individuals the chance to to challenge particular communication strategies before courts or legal tribunals. The result is that public authorities largely have a free reign to communicate how they wish and do not have to have to comply with a range of requirements (e.g. relating to form and substantive) content) that would in general apply to most forms of official administrative act.

  8. Experimental quantum control landscapes: Inherent monotonicity and artificial structure

    International Nuclear Information System (INIS)

    Roslund, Jonathan; Rabitz, Herschel

    2009-01-01

    Unconstrained searches over quantum control landscapes are theoretically predicted to generally exhibit trap-free monotonic behavior. This paper makes an explicit experimental demonstration of this intrinsic monotonicity for two controlled quantum systems: frequency unfiltered and filtered second-harmonic generation (SHG). For unfiltered SHG, the landscape is randomly sampled and interpolation of the data is found to be devoid of landscape traps up to the level of data noise. In the case of narrow-band-filtered SHG, trajectories are taken on the landscape to reveal a lack of traps. Although the filtered SHG landscape is trap free, it exhibits a rich local structure. A perturbation analysis around the top of these landscapes provides a basis to understand their topology. Despite the inherent trap-free nature of the landscapes, practical constraints placed on the controls can lead to the appearance of artificial structure arising from the resultant forced sampling of the landscape. This circumstance and the likely lack of knowledge about the detailed local landscape structure in most quantum control applications suggests that the a priori identification of globally successful (un)constrained curvilinear control variables may be a challenging task.

    1997-01-01

    A Dynamic Cell Structure (DCS) Neural Network was developed which learns topology representing networks (TRNS) of F-15 aircraft aerodynamic stability and control derivatives. The network is integrated into a direct adaptive tracking controller. The combination produces a robust adaptive architecture capable of handling multiple accident and off- nominal flight scenarios. This paper describes the DCS network and modifications to the parameter estimation procedure. The work represents one step towards an integrated real-time reconfiguration control architecture for rapid prototyping of new aircraft designs. Performance was evaluated using three off-line benchmarks and on-line nonlinear Virtual Reality simulation. Flight control was evaluated under scenarios including differential stabilator lock, soft sensor failure, control and stability derivative variations, and air turbulence.

    The computer based control system for FTU (Frascati Tokamak Upgrade) machine is a distributed intelligence control system consisting of various subsystems, called ''specific units''. A specific unit can work as a stand-alone small system or as a part of more complex systems, together with other units, in any possible combination. In the case of combined units working mode, a dedicated specific unit performs supervisory functions. Communication between specific units is done on a dedicated bus-like network, in the form of temporary master-slave relationship. There are three groups of specific units: Plant Control Units, Supervisory Control Unit and Synoptic Handling Unit. Performances and structures of these specific units are described. In addition, a very simple hard-wired safety system works in parallel with the computer based control system, in order to save personnel and apparatus. (author)

    1992-01-01

    The fast computation of geometry control in adaptive truss structures involves two distinct parts: the efficient integration of the inverse kinematic differential equations that govern the geometry control and the fast computation of the Jacobian, which appears on the right-hand-side of the inverse kinematic equations. This paper present an efficient parallel implementation of the Jacobian computation on an MIMD machine. Large speedup from the parallel implementation is obtained, which reduces the Jacobian computation to an O(M-squared/n) procedure on an n-processor machine, where M is the number of members in the adaptive truss. The parallel algorithm given here is a good candidate for on-line geometry control of adaptive structures using attached processors.

    2009-12-01

    To be effective, infection prevention and control must be integrated into the complex and multiple interlinking systems within a hospital's management structure. Each of the systems must consider how activity associated with it can be optimised to minimise infection risk to patients. The components of an organisational structure to achieve these quality assurance and patient safety aims are discussed. The use of performance management tools in relation to infection control metrics is reviewed, and the use of hospital-acquired infection as a proxy indicator for deficiencies of system management is considered. Infection prevention and control cannot be the role and responsibility of a single individual or a small dedicated team; rather it should be a priority at all levels and integrated within all management systems, including the research and educational agendas.

    This book systematizes recent research work on variable-structure control. It is self-contained, presenting necessary mathematical preliminaries so that the theoretical developments can be easily understood by a broad readership. The text begins with an introduction to the fundamental ideas of variable-structure control pertinent to their application in complex nonlinear systems. In the core of the book, the authors lay out an approach, suitable for a large class of systems, that deals with system uncertainties with nonlinear bounds. Its treatment of complex systems in which limited measurement information is available makes the results developed convenient to implement. Various case-study applications are described, from aerospace, through power systems to river pollution control with supporting simulations to aid the transition from mathematical theory to engineering practicalities. The book addresses systems with nonlinearities, time delays and interconnections and considers issues such as stabilization, o...

    Hybrid testing is a substructuring technique where a structure is emulated by modelling a part of it in a numerical model while testing the remainder experimentally. Previous research in hybrid testing has been performed on multi-component structures e.g. damping fixtures, however in this paper...... a hybrid testing platform is introduced for single-component hybrid testing. In this case, the boundary between the numerical model and experimental setup is defined by multiple Degrees-Of-Freedoms (DOFs) which highly complicate the transferring of response between the two substructures. Digital Image...... Correlation (DIC) is therefore implemented for displacement control of the experimental setup. The hybrid testing setup was verified on a multicomponent structure consisting of a beam loaded in three point bending and a numerical structure of a frame. Furthermore, the stability of the hybrid testing loop...

    Full Text Available Based on lines cluster approaching theory and inspired by the traditional exponent reaching law method, a new control method, lines cluster approaching mode control (LCAMC method, is designed to improve the parameter simplicity and structure optimization of the control system. The design guidelines and mathematical proofs are also given. To further improve the tracking performance and the inhibition of the white noise, connect the active disturbance rejection control (ADRC method with the LCAMC method and create the extended state observer based lines cluster approaching mode control (ESO-LCAMC method. Taking traditional servo control system as example, two control schemes are constructed and two kinds of comparison are carried out. Computer simulation results show that LCAMC method, having better tracking performance than the traditional sliding mode control (SMC system, makes the servo system track command signal quickly and accurately in spite of the persistent equivalent disturbances and ESO-LCAMC method further reduces the tracking error and filters the white noise added on the system states. Simulation results verify the robust property and comprehensive performance of control schemes.

  3. A Jacobian singularity based robust controller design for structured uncertainty

    Science.gov (United States)

    Brown, Brandon

    Any real system will have differences between the mathematical model response and the response of the true system it represents. These differences can come from external disturbances, incomplete modeling of the dynamics (unstructured uncertainty) or simply incorrect or changing parameter values (structured uncertainty) in the model. Sources of unstructured uncertainty are unavoidable in real systems, so a controller design must always consider robustness to these effects. In many cases, when the sources of structured uncertainty are addressed as another source of unstructured uncertainty, the resulting controller design is conservative. By accurately addressing and designing a controller for the structured uncertainty, large benefits in the controller performance can be generated since the conservative bound is reduced. The classical approach to output shaping of a system involves a feedback loop since this architecture is more robust to differences between the mathematical model and the true system. This dissertation will present an approach to design a feedback controller which is robust to structured uncertainties in a plant, in an accurate and minimal way. The approach begins by identifying a critical set of system parameters which will be proven to represent the full set of system parameters in the Nyquist plane. This critical set is populated by all parameter vectors which satisfy a developed deficiency condition and is the minimal set which will contribute to the Nyquist plane portraits. The invariance of this critical set to control structure is shown explicitly. An improvement of previous work is the addition of a numerical solution technique which guarantees that all critical points are found. The presented approach will allow for the designer set minimum relative stability margins, such as gain and phase margins, which previous work could not compute accurately or with confidence of the results. A robust controller is designed with respect to this

    2015-05-01

    Full Text Available The piezoelectric actuator has gained popularity over the last few years. Attention has been directed towards the study of their electromechanical response in active repair and the control of damaged structures. This has been made possible through the development of various numerical and analytical techniques for such studies. The shift of focus towards the piezoelectric based approaches has been due to their advantages, which include strategic cost benefits in maintenance, as well as an increase in the life cycle of the repaired structures. Furthermore, adhesively bonded joints are widely used in the manufacturing and repairing of structures in many industries, especially automotive and aerospace engineering. This is due to the requirement for lightweight materials as well as the potential adhesive used to join materials with different characteristics. The piezoelectric actuator has also shown the capacity in controlling and lowering the shear stress concentration and joint edge peel in adhesively bonded joint systems. The structure’s control of stress and repair can generally be viewed as a reinforcement that influences the structure’s damage tolerance. Therefore, the interest of this review is on the applications of the piezoelectric actuators in both structural damage and the bonded adhesive joint system. The specific goal is to recognize the contemporary scientific challenges, including future opportunities.

    The role of lipids in controlling water exchange is fundamentally a matter of molecular organization. In the present study we have observed that in snake molt the water permeability drastically varies among species living in different climates and habitats. The analysis of molts from four snake species: tiger snake, Notechis scutatus, gabon viper, Bitis gabonica, rattle snake, Crotalus atrox, and grass snake, Natrix natrix, revealed correlations between the molecular composition and the structural organization of the lipid-rich mesos layer with control in water exchange as a function of temperature. It was discovered, merging data from micro-diffraction and micro-spectroscopy with those from thermal, NMR and chromatographic analyses, that this control is generated from a sophisticated structural organization that changes size and phase distribution of crystalline domains of specific lipid molecules as a function of temperature. Thus, the results of this research on four snake species suggest that in snake skins different structured lipid layers have evolved and adapted to different climates. Moreover, these lipid structures can protect, "safety", the snakes from water lost even at temperatures higher than those of their usual habitat. Copyright © 2013 Elsevier Inc. All rights reserved.

    The interest of this paper is to develop a general and systematic robust control methodology for active vibration control of flexible structures. For this purpose, first phase and gain control policies are proposed to impose qualitative frequency-dependent requirements on the controller to consider a complete set of control objectives. Then the proposed control methodology is developed by employing phase and gain control policies in the dynamic output feedback H ∞  control: according to the set of control objectives, phase and gain control policies incorporate necessary weighting functions and determine them in a rational and systematic way; on the other hand, with the appropriate weighting functions efficient H ∞  control algorithms can automatically realize phase and gain control policies and generate a satisfactory H ∞  controller. The proposed control methodology can be used for both SISO and MIMO systems with collocated or non-collocated sensors and actuators. In this paper, it is validated on a non-collocated piezoelectric cantilever beam. Both numerical simulations and experimental results demonstrate the effectiveness of the proposed control methodology. (paper)

    Tanabe, Tomoyuki; Maruyama, Masahiro

    2016-01-01

    Nuclear safety regulations enforced after Fukushima Daiichi Nuclear Accident under the Nuclear Reactor Regulation Act face the following regulatory problems that involve potential risk factors for nuclear businesses; 1) 'entity based regulation' unable to cope with business cessation or bankruptcy of the entity subject of regulation, 2) potential risk of the Nuclear Regulation Authority's inappropriate involvement in nuclear industry policy beyond their duty, and 3) compliance of backfits under vague regulations. In order to alleviate them, this report, through analyzing these regulatory problems from the view point of sound development of the nuclear industry, proposes the following regulatory reforms; (1) To clarify the rule for industry policy in nuclear regulations and enable the authority, Ministry of Economy, Trade and Industry, to choose most appropriate industrial policy measure. (2) Through establishing safety goals as measures to promote continuous improvement of nuclear safety regulations, to stimulate timely adjustments of the regulations, and to introduce a legal mechanism into the nuclear regulation systems under which validity of administrative law and its application can be checked.

    Ocean energy is a novel renewable energy resource being developed as part of the push towards a 'Blue Economy'. The literature on ocean energy has focused on technical, environmental, and, increasingly, social and political aspects. Legal and regulatory factors have received less attention, despite their importance in supporting this new technology and ensuring its sustainable development. In this Issue Brief, we set out some key legal challenges for the development of ocean energy technologies, structured around the following core themes of marine governance: (i) international law; (ii) environmental impacts; (iii) rights and ownership; (iv) consenting processes; and (v) management of marine space and resources.

  14. Collaborative Legal Pluralism

    2017-01-01

    Full Text Available Legal pluralism calls into question the monopoly of the modern state when it comes to the production and the enforcement of norms. It rests on the assumption that juridical normativity and state organization can be dissociated. From an early modern historian’s perspective, such an assumption makes perfect sense, the plural nature of the legal order being the natural state of affairs in imperial spaces across the globe in the sixteenth and seventeenth centuries. This article will provide a case study of the collaborative nature of the interaction between spiritual and temporal legal orders in Spain and its overseas territories as conceived by Tomás de Mercado (ca. 1520–1575, a major theologian from the School of Salamanca. His treatise on trade and contracts (1571 contained an extended discussion of the government’s attempt to regulate the grain market by imposing a maximum price. It will be argued that Mercado’s view on the bindingness of economic regulations in conscience allowed for the internalization of the regulatory power of the nascent state. He called upon confessors to be strict enforcers of state law, considering them as fathers of the republic as much as fathers of faith. This is illustrative of the »collaborative form of legal pluralism« typical of the osmotic relationship between Church and State in the early modern Spanish empire. It contributed to the moral justification of state jurisdictions, while at the same time, guaranteeing a privileged role for theologians and religious leaders in running the affairs of the state.

    2016-04-01

    Full Text Available The analysis of the international legal framework for media in a real structural form is a challenge that needs to be scientifically proven because of the exceptional role of media in general and its constant and substantial impact on the democratic processes taking place in the world. If we analyze media through the eyes of history, we cannot ignore the impression of the exceptional importance of freedom of expression as the source and promoter of many substantive changes and valuable components in the overall functioning of social and political settings. In this regard, special attention is given to the impact of media on contemporary trends related to the EU integration process, the development of democracy and the rule of law. It particularly emphasizes the freedom of expression, respect for values and standards principles, human rights and freedoms. The purpose of this paper is to analyze the international legal framework for the media and to show the determination of the most important covenants which represent a source of media law containing rules for the creation and implementation of media freedom, the expressive quality of ideas and definitely and inevitably this paper stresses the power of the media.

  17. Power system damping - Structural aspects of controlling active power

    Energy Technology Data Exchange (ETDEWEB)

    Samuelsson, O.

    1997-04-01

    Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. A consequence is that power system damping is reduced, leading to a risk of poorly damped power oscillations between the generators. This thesis proposes the use of controlled active loads to increase damping of such electro-mechanical oscillations. The focus is on structural aspects of controller interaction and of sensor and actuator placement. On-off control based on machine frequency in a single machine infinite bus system is analysed using energy function analysis and phase plane plots. An on-off controller with estimated machine frequency as input has been implemented. At a field test it damped oscillations of a 0.9 MW hydro power generator by controlling a 20kW load. The linear analysis uses two power system models with three and twenty-three machines respectively. Each damper has active power as output and local bus frequency or machine frequency as input. The power system simulator EUROSTAG is used both for generation of the linearized models and for time simulations. Measures of active power mode controllability and phase angle mode observability are obtained from the eigenvectors of the differential-algebraic models. The geographical variation in the network of these quantities is illustrated using the resemblance to bending modes of flexible mechanical structures. Eigenvalue sensitivities are used to determine suitable damper locations. A spring-mass equivalent to an inter-area mode provides analytical expressions, that together with the concept of impedance matching explain the structural behaviour of the power systems. For large gains this is investigated using root locus plots. 64 refs, 99 figs, 20 tabs

  18. Simultaneous Structural Health Monitoring and Vibration Control of Adaptive Structures Using Smart Materials

    Directory of Open Access Journals (Sweden)

    Myung-Hyun Kim

    2002-01-01

    Full Text Available The integration of actuators and sensors using smart materials enabled various applications including health monitoring and structural vibration control. In this study, a robust control technique is designed and implemented in order to reduce vibration of an active structure. Special attention is given to eliminating the possibility of interaction between the health monitoring system and the control system. Exploiting the disturbance decoupling characteristic of the sliding mode observer, it is demonstrated that the proposed observer can eliminate the possible high frequency excitation from the health monitoring system. At the same time, a damage identification scheme, which tracks the changes of mechanical impedance due to the presence of damage, has been applied to assess the health condition of structures. The main objective of this paper is to examine the potential of combining the two emerging techniques together. Using the collocated piezoelectric sensors/actuators for vibration suppression as well as for health monitoring, this technique enabled to reduce the number of system components, while enhancing the performance of structures. As an initial study, both simulation and experimental investigations were performed for an active beam structure. The results show that this integrated technique can provide substantial vibration reductions, while detecting damage on the structure at the same time.

    Surface-initiated atom-transfer radical polymerization is used to synthesize particle brushes with controlled fraction of extended and relaxed conformations of surface-grafted chains. In the semidilute brush limit, the grafting of polymeric ligands is shown to facilitate the formation of ordered yet plastic-compliant particle array structures in which chain entanglements give rise to fracture through a polymer-like crazing process that dramatically increases the toughness and flexibility of the particle assembly.

    A simple and versatile strategy is developed for one-step fabrication of uniform polymeric microparticles with controllable highly interconnected hierarchical porous structures. Monodisperse water-in-oil-in-water (W/O/W) emulsions, with methyl methacrylate, ethylene glycol dimethacrylate, and glycidyl methacrylate as the monomer-containing oil phase, are generated from microfluidics and used for constructing the microparticles. Due to the partially miscible property of oil/aqueous phases, the monodisperse W/O/W emulsions can deform into desired shapes depending on the packing structure of inner aqueous microdrops, and form aqueous nanodrops in the oil phase. The deformed W/O/W emulsions allow template syntheses of highly interconnected hierarchical porous microparticles with precisely and individually controlled pore size, porosity, functionality, and particle shape. The microparticles elaborately combine the advantages of enhanced mass transfer, large functional surface area, and flexibly tunable functionalities, providing an efficient strategy to physically and chemically achieve enhanced synergetic performances for extensive applications. This is demonstrated by using the microparticles for oil removal for water purification and protein adsorption for bioseparation. The method proposed in this study provides full versatility for fabrication of functional polymeric microparticles with controllable hierarchical porous structures for enhancing and even broadening their applications.

    Tuthill, A.M.; White, K.D.

    1997-01-01

    The Salmon River ice jam problem was investigated and a conceptual design for a breakup ice control structure was developed. Historical ice jam events were reviewed and an ice observation program was conducted during the winter of 1994-95. The factors affecting ice jam frequency and severity were examined. The factors included daily temperature, rainfall quantity and intensity, Salmon River stage and discharge, and Connecticut River tide levels. First, a numerical model was developed to simulate a worst case scenario for ice jams, followed by a conceptual design for a concrete pier ice control structure under two ice breakup scenarios. The first scenario assumed that a semi-intact ice sheet would rest against the piers and retain a floating equilibrium jam upstream, allowing water discharge to pass beneath. The second scenario was based on the assumption that a grounded ice jam in direct contact with the piers would divert water flow around the structure via an armored channel in the overbank area. An ice retention structure consisting of a row of concrete piers, spaced across the main channel, 60 m upstream of an existing dam, was proposed. 11 refs., 6 figs

    2014-09-01

    Full Text Available The proliferation of technology emphasized new forms of payment. During the last years, current literature highlighted the role of virtual currency, the channels of payment through digital coins and the importance of assimilation of such platforms. Bitcoin or BTC is known as a digital coin, issued for the first time in 2009 and based on a peer to peer system. The difference from other forms of payment is that BTC is not controlled by any institution or central authority. BTC transactions have grown rapidly, ”asking" for regulation measures or legal approval of governments. Although BTC has become very popular, the market is poor and unfortunately of no confidence. There is a lack of regulation which can determine a number of risks associated with criminal financing activities. However, the legal status of Bitcoin is present in many European countries like Belgium, Bulgaria, Denmark, Finland, Germany, Lithuania, Norway, Poland, Slovenia, Switzerland or Turkey. Also, this type of currency has experienced a rapid evolution among coffee shops and restaurants.

    Arrieta, Andres F.; van Gemmeren, Valentin; Anderson, Aaron J.; Weaver, Paul M.

    2018-02-01

    Compliance-based morphing structures have the potential to offer large shape adaptation, high stiffness and low weight, while reducing complexity, friction, and scalability problems of mechanism based systems. A promising class of structure that enables these characteristics are multi-stable structures given their ability to exhibit large deflections and rotations without the expensive need for continuous actuation, with the latter only required intermittently. Furthermore, multi-stable structures exhibit inherently fast response due to the snap-through instability governing changes between stable states, enabling rapid configuration switching between the discrete number of programmed shapes of the structure. In this paper, the design and utilisation of the inherent nonlinear dynamics of bi-stable twisting I-beam structures for actuation with low strain piezoelectric materials is presented. The I-beam structure consists of three compliant components assembled into a monolithic single element, free of moving parts, and showing large deflections between two stable states. Finite element analysis is utilised to uncover the distribution of strain across the width of the flange, guiding the choice of positioning for piezoelectric actuators. In addition, the actuation authority is maximised by calculating the generalised coupling coefficient for different positions of the piezoelectric actuators. The results obtained are employed to tailor and test I-beam designs exhibiting desired large deflection between stable states, while still enabling the activation of snap-through with the low strain piezoelectric actuators. To this end, the dynamic response of the I-beams to piezoelectric excitation is investigated, revealing that resonant excitations are insufficient to dynamically trigger snap-through. A novel bang-bang control strategy, which exploits the nonlinear dynamics of the structure successfully triggers both single and constant snap-through between the stable states

    2017-03-01

    Double-rotator-structure ternary optical processor (DRSTOP) has two characteristics, namely, giant data-bits parallel computing and reconfigurable processor, which can handle thousands of data bits in parallel, and can run much faster than computers and other optical computer systems so far. In order to put DRSTOP into practical application, this paper established a series of methods, namely, task classification method, data-bits allocation method, control information generation method, control information formatting and sending method, and decoded results obtaining method and so on. These methods form the control mechanism of DRSTOP. This control mechanism makes DRSTOP become an automated computing platform. Compared with the traditional calculation tools, DRSTOP computing platform can ease the contradiction between high energy consumption and big data computing due to greatly reducing the cost of communications and I/O. Finally, the paper designed a set of experiments for DRSTOP control mechanism to verify its feasibility and correctness. Experimental results showed that the control mechanism is correct, feasible and efficient.

  12. Recentering Shape Memory Alloy Passive Damper for Structural Vibration Control

    Directory of Open Access Journals (Sweden)

    Hui Qian

    2013-01-01

    Full Text Available This paper presents a preliminary study on the evaluation of an innovative energy dissipation system with shape memory alloys (SMAs for structural seismic protection. A recentering shape memory alloy damper (RSMAD, in which superelastic nitinol wires are utilized as energy dissipation components, is proposed. Improved constitutive equations based on Graesser and Cozzarelli model are proposed for superelastic nitinol wires used in the damper. Cyclic tensile-compressive tests on the damper with various prestrain under different loading frequencies and displacement amplitudes were conducted. The results show that the hysteretic behaviors of the damper can be modified to best fit the needs for passive structural control applications by adjusting the pretension of the nitinol wires, and the damper performance is not sensitive to frequencies greater than 0.5 Hz. To assess the effectiveness of the dampers for structural seismic protection, nonlinear time history analysis on a ten-story steel frame with and without the dampers subjected to representative earthquake ground motions was performed. The simulation results indicate that superelastic SMA dampers are effective in mitigating the structural response of building structures subjected to strong earthquakes.

    A Real-Time Workstation for Computer-Aided Control Engineering has been developed jointly by the Communications Research Centre (CRC) and Ruhr-Universitaet Bochum (RUB), West Germany. The system is presently used for the development and experimental verification of control techniques for large space systems with significant structural flexibility. The Real-Time Workstation essentially is an implementation of RUB's extensive Computer-Aided Control Engineering package KEDDC on an INTEL micro-computer running under the RMS real-time operating system. The portable system supports system identification, analysis, control design and simulation, as well as the immediate implementation and test of control systems. The Real-Time Workstation is currently being used by CRC to study control/structure interaction on a ground-based structure called DAISY, whose design was inspired by a reflector antenna. DAISY emulates the dynamics of a large flexible spacecraft with the following characteristics: rigid body modes, many clustered vibration modes with low frequencies and extremely low damping. The Real-Time Workstation was found to be a very powerful tool for experimental studies, supporting control design and simulation, and conducting and evaluating tests withn one integrated environment.

    2014-12-01

    A recent field expedition in Central Java targeted the mapping and sampling of several piercements structures in central Java (Indonesia), most of which have never been documented before. Here, at least seven structures erupting mud water and gas are distributed along a NE-SW alignment that extends for about 10 kilometers. Some of the mapped structures (Bledug Kuwu, Bledug Cangkring Krabagan, Mendikil, Banjarsari, Krewek) have been named after the neighboring local village. None of these have obvious elevation despite the vigorous emission of gas and mud, suggesting that significant caldera collapse is ongoing. Among the most relevant: Bledug Kuwu is certainly the most impressive structure with three main eruption sites in the crater area bursting more than 5 m large hot mud bubbles. Similar characteristics are present at the smaller (200 m in diameter) Bledug Cangkring Krabagan, that is also surrounded by numerous pools and gryphons seeping around the main crater. The smaller sized Mendikil is the only visited structure that, at the moment of the sampling, did not show seepage of hot fluids. Banjarsari and Krewek (up to 200 m wide) are characterized by scattered hot water-dominated pools where gas is vented vigorously. In particular the hot pools are systematically covered by travertine concretions. Water and gas geochemisty confirms the seepage of CO2 dominated gas and water with hydrothermal signature. The investigated structures appear to follow an obvious NE-SW oriented lineament that most likely coincides with a tectonic structure (fault?) that controls their location. Indeed the field observations and the analyses suggest that likely scenario is that this fault (?) acts as a preferential pathway for the expulsion of hydrothermal fluids to the surface. Very little is known about this region, neither is known why several of these structures erupt hot mud despite their significant distance from the two closest volcanic structures (i.e. Mt. Muria 60 km to the NW

    Full Text Available Advances in the information and communication technologies have led to the availability of a range of primary and secondary legal research publications online via the Internet, rather than on other storing devices such as compact discs or publications in the print media. Not only has information and communication technology (ICT impacted on the availability of legal information resources, but its effects are also noticed in various law-related areas such as legal practice management, legal education, corporate governance and the law per se. The question addressed by this article is whether the application of ICTs has an effect on the practice of law, and specifically whether information and knowledge management affects the processes of legal research in modern legal practice. Various issues are considered in this regard, including what the concept of knowledge management (KM entails in a law firm and what the current KM trends in South African law firms are. The article investigates global trends in the application of ICTs for legal research purposes, what the specific applications of KM in support of legal research may be, how information technology applications and KM systems and strategies can support the legal research process, and what the benefits of KM are to legal research. It finally discusses the impact technology has had on the skills required of competitive legal professionals.

A central question in the field is how ATP binding and hydrolysis are coupled to substrate translocation through the central channel of ring-forming AAA+ proteins. In this mini-review, we will discuss structural elements present in AAA+ proteins involved in protein quality control, drawing similarities to their known role in substrate interaction by AAA+ proteins involved in DNA translocation. Elements to be discussed include the pore loop-1, the Inter-Subunit Signaling (ISS motif, and the Pre-Sensor I insert (PS-I motif. Lastly, we will summarize our current understanding on the inter-relationship of those structural elements and propose a model how ATP binding and hydrolysis might be coupled to polypeptide translocation in protein quality control machines.

    Selective non-covalent interactions have been widely exploited in solution-based chemistry to direct the assembly of molecules into nanometre-sized functional structures such as capsules, switches and prototype machines. More recently, the concepts of supramolecular organization have also been applied to two-dimensional assemblies on surfaces stabilized by hydrogen bonding, dipolar coupling or metal co-ordination. Structures realized to date include isolated rows, clusters and extended networks, as well as more complex multi-component arrangements. Another approach to controlling surface structures uses adsorbed molecular monolayers to create preferential binding sites that accommodate individual target molecules. Here we combine these approaches, by using hydrogen bonding to guide the assembly of two types of molecules into a two-dimensional open honeycomb network that then controls and templates new surface phases formed by subsequently deposited fullerene molecules. We find that the open network acts as a two-dimensional array of large pores of sufficient capacity to accommodate several large guest molecules, with the network itself also serving as a template for the formation of a fullerene layer.

  1. Structural sensing of interior sound for active control of noise in structural-acoustic cavities.

    Bagha, Ashok K; Modak, S V

    2015-07-01

    This paper proposes a method for structural sensing of acoustic potential energy for active control of noise in a structural-acoustic cavity. The sensing strategy aims at global control and works with a fewer number of sensors. It is based on the established concept of radiation modes and hence does not add too many states to the order of the system. Acoustic potential energy is sensed using a combination of a Kalman filter and a frequency weighting filter with the structural response measurements as the inputs. The use of Kalman filter also makes the system robust against measurement noise. The formulation of the strategy is presented using finite element models of the system including that of sensors and actuators so that it can be easily applied to practical systems. The sensing strategy is numerically evaluated in the framework of Linear Quadratic Gaussian based feedback control of interior noise in a rectangular box cavity with a flexible plate with single and multiple pairs of piezoelectric sensor-actuator patches when broadband disturbances act on the plate. The performance is compared with an "acoustic filter" that models the complete transfer function from the structure to the acoustic domain. The sensing performance is also compared with a direct estimation strategy.

  2. Grain Structure Control of Additively Manufactured Metallic Materials

    Full Text Available Grain structure control is challenging for metal additive manufacturing (AM. Grain structure optimization requires the control of grain morphology with grain size refinement, which can improve the mechanical properties of additive manufactured components. This work summarizes methods to promote fine equiaxed grains in both the additive manufacturing process and subsequent heat treatment. Influences of temperature gradient, solidification velocity and alloy composition on grain morphology are discussed. Equiaxed solidification is greatly promoted by introducing a high density of heterogeneous nucleation sites via powder rate control in the direct energy deposition (DED technique or powder surface treatment for powder-bed techniques. Grain growth/coarsening during post-processing heat treatment can be restricted by presence of nano-scale oxide particles formed in-situ during AM. Grain refinement of martensitic steels can also be achieved by cyclic austenitizing in post-processing heat treatment. Evidently, new alloy powder design is another sustainable method enhancing the capability of AM for high-performance components with desirable microstructures.

    When a luminescent ion is confined in a system characterized by one or more specific properties such as spatial size, geometrical dimension and shape, refractive index, local crystal field, cut-off vibrational energy and so on, it's possible to control its emission. The control of branching ratios as a function of the composition, the luminescence enhancement induced by a photonic crystal, or the laser action in a microresonator, are well known examples of light control. Photonic glass-based structures are extremely viable systems to exploit the above mentioned properties and in our research team we have successfully fabricated luminescent photonic structures by different techniques, including sol-gel, rf sputtering, drawing, melting, and physical vapour deposition. Here we will discuss some of them with the aim to make the reader aware of the chemical-physical properties related to each specific system. We will demonstrate that glass ceramic waveguides in some cases present superior spectroscopic properties in respect to the parent glass, that compositional properties can play a positive role in reducing luminescence quenching and in developing novel planar waveguides and fibers, that colloids allow to obtain high internal quantum efficiency and that photonic crystals, microcavities and microresonators can enable the handling of the rare earth luminescence. Finally, the pros and cons of the systems and of the different techniques employed for their fabrication will be discussed and some perspectives concerning the glass photonics will be proposed looking at both possible applications and investigation of physical properties.

  4. Biologically inspired autonomous structural materials with controlled toughening and healing

    2010-04-01

    The field of structural health monitoring (SHM) has made significant contributions in the field of prognosis and damage detection in the past decade. The advantageous use of this technology has not been integrated into operational structures to prevent damage from propagating or to heal injured regions under real time loading conditions. Rather, current systems relay this information to a central processor or human operator, who then determines a course of action such as altering the mission or scheduling repair maintenance. Biological systems exhibit advanced sensory and healing traits that can be applied to the design of material systems. For instance, bone is the major structural component in vertebrates; however, unlike modern structural materials, bone has many properties that make it effective for arresting the propagation of cracks and subsequent healing of the fractured area. The foremost goal for the development of future adaptive structures is to mimic biological systems, similar to bone, such that the material system can detect damage and deploy defensive traits to impede damage from propagating, thus preventing catastrophic failure while in operation. After sensing and stalling the propagation of damage, the structure must then be repaired autonomously using self healing mechanisms motivated by biological systems. Here a novel autonomous system is developed using shape memory polymers (SMPs), that employs an optical fiber network as both a damage detection sensor and a network to deliver stimulus to the damage site initiating adaptation and healing. In the presence of damage the fiber optic fractures allowing a high power laser diode to deposit a controlled level of thermal energy at the fractured sight locally reducing the modulus and blunting the crack tip, which significantly slows the crack growth rate. By applying a pre-induced strain field and utilizing the shape memory recovery effect, thermal energy can be deployed to close the crack and return

    Full Text Available The necessity of examination of every case within its peculiar conditions in social sciences requires different approaches complying with the spirit and nature of social sciences. Multiple realities require different and various perceptual interpretations. In modern world and social sciences, interpretation of perception of valued and multi-valued have been started to be understood by the principles of fuzziness and fuzzy logic. Having the verbally expressible degrees of truthness such as true, very true, rather true, etc. fuzzy logic provides the opportunity for the interpretation of especially complex and rather vague set of information by flexibility or equivalence of the variables’ of fuzzy limitations. The methods and principles of fuzzy logic can be benefited in examination of the methodological problems of law, especially in the applications of filling the legal loopholes arising from the ambiguities and interpretation problems in order to understand the legal rules in a more comprehensible and applicable way and the efficiency of legal implications. On the other hand, fuzzy logic can be used as a technical legal method in legal education and especially in legal case studies and legal practice applications in order to provide the perception of law as a value and the more comprehensive and more quality perception and interpretation of value of justice, which is the core value of law. In the perception of what happened as it has happened in legal relationships and formations, the understanding of social reality and sociological legal rules with multi valued sense perspective and the their applications in accordance with the fuzzy logic’s methods could create more equivalent and just results. It can be useful for the young lawyers and law students as a facilitating legal method especially in the materialization of the perception and interpretation of multi valued and variables.

  8. Homogenization in the Modelling of Volume-Controlled Elastic Structures

    International Nuclear Information System (INIS)

    Russell, David L.

    2007-01-01

    The background for this article is the question of modification of the geometric configuration of an elastic structure by means of 'volume'-type actuation. In this actuation mode stresses are applied to the elastic body by injection/extraction of a fluid into, or from, a large number of vacuoles in the elastic 'matrix' material. Previous articles by the author, and others, have examined this process and studied its effectiveness in the context of a 'naive' continuous model. The present paper develops modified models in the two-dimensional case by applying the 'multiple scales' homogenization method to elastic bodies with increasingly small and numerous vacuoles arranged in a rectangularly periodic structure. The process leads to a modification of the naive model potentially useful in future elastic system control research

  9. Argumentation in Legal Reasoning

    Science.gov (United States)

    Bench-Capon, Trevor; Prakken, Henry; Sartor, Giovanni

    A popular view of what Artificial Intelligence can do for lawyers is that it can do no more than deduce the consequences from a precisely stated set of facts and legal rules. This immediately makes many lawyers sceptical about the usefulness of such systems: this mechanical approach seems to leave out most of what is important in legal reasoning. A case does not appear as a set of facts, but rather as a story told by a client. For example, a man may come to his lawyer saying that he had developed an innovative product while working for Company A. Now Company B has made him an offer of a job, to develop a similar product for them. Can he do this? The lawyer firstly must interpret this story, in the context, so that it can be made to fit the framework of applicable law. Several interpretations may be possible. In our example it could be seen as being governed by his contract of employment, or as an issue in Trade Secrets law.

    The diverse functionalities of RNA can be attributed to its capacity to form complex and varied structures. The recent proliferation of new structure probing techniques coupled with high-throughput sequencing has helped RNA studies expand in both scope and depth. Despite differences in techniques, most experiments face similar challenges in reproducibility due to the stochastic nature of chemical probing and sequencing. As these protocols expand to transcriptome-wide studies, quality control becomes a more daunting task. General and efficient methodologies are needed to quantify variability and quality in the wide range of current and emerging structure probing experiments. We develop metrics to rapidly and quantitatively evaluate data quality from structure probing experiments, demonstrating their efficacy on both small synthetic libraries and transcriptome-wide datasets. We use a signal-to-noise ratio concept to evaluate replicate agreement, which has the capacity to identify high-quality data. We also consider and compare two methods to assess variability inherent in probing experiments, which we then utilize to evaluate the coverage adjustments needed to meet desired quality. The developed metrics and tools will be useful in summarizing large-scale datasets and will help standardize quality control in the field.

    2013-01-01

    An apparatus and method for the controlled fabrication of nanostructures using catalyst retaining structures is disclosed. The apparatus includes one or more modified force microscopes having a nanotube attached to the tip portion of the microscopes. An electric current is passed from the nanotube to a catalyst layer of a substrate, thereby causing a localized chemical reaction to occur in a resist layer adjacent the catalyst layer. The region of the resist layer where the chemical reaction occurred is etched, thereby exposing a catalyst particle or particles in the catalyst layer surrounded by a wall of unetched resist material. Subsequent chemical vapor deposition causes growth of a nanostructure to occur upward through the wall of unetched resist material having controlled characteristics of height and diameter and, for parallel systems, number density.

    This work presents a novel nonlinear control system designed for interferometry based on variable structure control and sliding modes. This approach can fully compensate the nonlinear behavior of the interferometer and lead to high accuracy control for large disturbances, featuring low cost, ease of implementation and high robustness, without a reset circuit (when compared with a linear control system). A deep stability analysis was accomplished and the global asymptotic stability of the system was proved. The results showed that the nonlinear control is able to keep the interferometer in the quadrature point and suppress signal fading for arbitrary signals, sinusoidal signals, or zero input signal, even under strong external disturbances. The system showed itself suitable to characterize a multi-axis piezoelectric flextentional actuator, which displacements that are much smaller than half wavelength. The high robustness allows the system to be embedded and to operate in harsh environments as factories, bringing the interferometry outside the laboratory.

    Full Text Available The multidimensional structure of legal consciousness, in which the norms of different orders collide, and the intricate intertwining of cognitive, emotive and behavioral components cannot be described in just one system of representations. This article considers conceptual bases of the study of moral and legal consciousness on the example of value-cognitive dilemmas. The author presents interpretations of the concept “situation” in the works of Russian and Western scientists, identifies its general theoretical bases and analyzes its potential in the study of moral and legal consciousness; suggests as one of the ways to find and identify determinants of moral and legal consciousness identification of specific decisions made by individuals in a variety of small-scale short situations in the given frame and normatively determined, because in the situational dilemma a social agent, whatever decision he makes, needs a rational reason and justification. The author describes the process of designing a technique on the basis of vignette-method and the method of controlled projection for the study of the conflict of multiple rationalities implying different models of justification in the structure of value choice.

    2002-11-01

    The reduction of the structure-borne road noise generated inside the cabin of an automobile is investigated using an Active Structural Acoustic Control (ASAC) approach. First, a laboratory test bench consisting of a wheel/suspension/lower suspension A-arm assembly has been developed in order to identify the vibroacoustic transfer paths (up to 250 Hz) for realistic road noise excitation of the wheel. Frequency Response Function (FRF) measurements between the excitation/control actuators and each suspension/chassis linkage are used to characterize the different transfer paths that transmit energy through the chassis of the car. Second, a FE/BE model (Finite/Boundary Elements) was developed to simulate the acoustic field of an automobile cab interior. This model is used to predict the acoustic field inside the cabin as a response to the measured forces applied on the suspension/chassis linkages. Finally, an experimental implementation of ASAC is presented. The control approach relies on the use of inertial actuators to modify the vibration behavior of the suspension and the automotive chassis such that its noise radiation efficiency is decreased. The implemented algorithm consists of a MIMO (Multiple-Input-Multiple-Output) feedforward configuration with a filtered-X LMS algorithm using an advanced reference signal (width FIR filters) using the Simulink/Dspace environment for control prototyping.

    There are legal regulations about sexual and reproductive rights of adolescents. However, this legal framework (LF) may have contradictory elements: there are laws assuring confidentiality and access to contraception at any age but there are other laws that consider any sexual contact with an adolescent younger than 14 a sexual assault, whose report to the legal authorities in mandatory. To explore the knowledge and clinical practice of primary health care (PHC) providers regarding prevention of teenage pregnancy. Qualitative study collecting data using semi-structured interviews made to midwives and directors of PHC centers. Analysis of the data was based on Grounded Theory. There is a differentiated clinical care for pregnancy prevention among adolescents if they are over 14 years old. This is due to the LF, specifically to the sexual crime’s law (19,927) and the law about regulation of the fertility (20,418). The differences affect health care, access and counseling about contraception and confidentiality. Healthcare of teenagers under the age of 14 is perceived as problematic for providers, due to the possible legal implications. The LF causes insecurity on health care providers and derives in a differentiated clinical approach according to the patient´s age. This is a barrier to provide timely and confidential access to counseling and contraception.

  3. Legal and Institutional Foundations of Adaptive Environmental ...

    Science.gov (United States)

    Legal and institutional structures fundamentally shape opportunities for adaptive governance of environmental resources at multiple ecological and societal scales. Properties of adaptive governance are widely studied. However, these studies have not resulted in consolidated frameworks for legal and institutional design, limiting our ability to promote adaptation and social-ecological resilience. We develop an overarching framework that describes the current and potential role of law in enabling adaptation. We apply this framework to different social-ecological settings, centers of activity, and scales, illustrating the multidimensional and polycentric nature of water governance. Adaptation typically emerges organically among multiple centers of agency and authority in society as a relatively self-organized or autonomous process marked by innovation, social learning, and political deliberation. This self-directed and emergent process is difficult to create in an exogenous, top-down fashion. However, traditional centers of authority may establish enabling conditions for adaptation using a suite of legal, economic, and democratic tools to legitimize and facilitate self-organization, coordination, and collaboration across scales. The principles outlined here provide preliminary legal and institutional foundations for adaptive environmental governance, which may inform institutional design and guide future scholarship. Adaptation typically emerges organically among m

    2009-01-01

    On the basis of variable structure control (VSC), an active queue management (AQM) controller is presented for a class of TCP communication networks. In the TCP/IP networks, the packet drop probability is limited between 0 and 1. Therefore, we modeled TCP/AQM as a rate-based non-linear system with a saturated input. The objective of the VSC-based AQM controller is to achieve the desired queue size and to guarantee the asymptotic stability of the closed-loop TCP non-linear system with saturated input. The performance and effectiveness of the proposed control law are then validated for different network scenarios through numerical simulations in both MATLAB and Network Simulator-2 (NS-2). Both sets of simulation results have confirmed that the proposed scheme outperforms other AQM schemes.

    In this paper are designed an analyzed the control ties of a 300MW fossil unit at different operation levels. The design and analysis were developed on an operation range of 50% to 100% load. The main control ties were studied among which are the feedwater flow, the superheating zone temperatures and the generated output. The technique used for the design is the decomposition in singular values (DSV) of the plant transference matrix. This is a recent technique that permits finding the most important interactions among output-input variables, over a significative frequencies range for the transference matrix of the plant. For this purpose utilizes the control properties of the transference matrix, such as: control effort, output-input interaction and ruggedness with respect to uncertainties. The control structures obtained were tested in a digital model of a fossil plant unit. A comparison study of both structures (original and modified) showed enhancement in the performance of the power plant with modified structure.

The Helmut-Schmidt-University has built up a full-scale test rig with an original A400M aircraft structure. This provides a good opportunity to develop and test active noise reduction systems in a realistic environment. The currently installed system consists of mechanical actuators and acoustical sensors. The actuators are called TVAs (Tuneable Vibration Absorber) and contain two spring-mass systems whose natural frequencies are adjusted to the BPFs (Blade Passage Frequency) of the propellers. The TVAs are mounted to the frames and the force direction is normal to the skin. The sensors are condenser microphones which are attached to the primary structure of the airframe. The TVAs are equipped with signal processing devices. These components carry out Fourier transforms and signal amplification for the sensor data and actuator signals. The communication between the TVAs and the central control unit is implemented by the CAN Bus protocol and mainly consists of complex coefficients for the sensor and actuator data. This paper describes the basic structure of the system, the hardware set-up and function tests of the controller. (paper)

    What is being suggested as the most feasible course now is a standfast position on the legal front; an aggressive, directed research program planned to answer the critical questions about marijuana; and a discouragement policy for adolescents. Legalization is not seen as a tenable solution for many reasons, and it is one that may be irreversible and regretted.

    1988-02-01

    Legal abortion-related mortality as reported to the Centers for Disease Control declined eightfold between 1972 and 1981. However, the causes of legal abortion mortality have changed over time. We reviewed all legal abortion-related deaths that occurred between 1972 and 1985 in the United States. We found that, although the absolute number of legal abortion-related deaths caused by general anesthesia complications did not increase, the proportion of such deaths increased significantly, from 7.7% between 1972 and 1975 to 29.4% between 1980 and 1985. Women who died of general anesthesia complications did not differ by age, presence of preexisting medical conditions, or type of facility from women who died of other causes. However, the proportion of deaths from general anesthesia complications was significantly higher among women of black and other races, women obtaining abortions during the first trimester, and women obtaining abortions in the Northeast. Our results indicate that at least 23 of the 27 deaths were due to hypoventilation and/or loss of airway resulting in hypoxia. Persons administering general anesthesia for abortion must be skilled in airway management as well as the provision of general anesthesia.

  18. Active structural acoustic control of helicopter interior multifrequency noise using input-output-based hybrid control

    Science.gov (United States)

    Ma, Xunjun; Lu, Yang; Wang, Fengjiao

    2017-09-01

    This paper presents the recent advances in reduction of multifrequency noise inside helicopter cabin using an active structural acoustic control system, which is based on active gearbox struts technical approach. To attenuate the multifrequency gearbox vibrations and resulting noise, a new scheme of discrete model predictive sliding mode control has been proposed based on controlled auto-regressive moving average model. Its implementation only needs input/output data, hence a broader frequency range of controlled system is modelled and the burden on the state observer design is released. Furthermore, a new iteration form of the algorithm is designed, improving the developing efficiency and run speed. To verify the algorithm's effectiveness and self-adaptability, experiments of real-time active control are performed on a newly developed helicopter model system. The helicopter model can generate gear meshing vibration/noise similar to a real helicopter with specially designed gearbox and active struts. The algorithm's control abilities are sufficiently checked by single-input single-output and multiple-input multiple-output experiments via different feedback strategies progressively: (1) control gear meshing noise through attenuating vibrations at the key points on the transmission path, (2) directly control the gear meshing noise in the cabin using the actuators. Results confirm that the active control system is practical for cancelling multifrequency helicopter interior noise, which also weakens the frequency-modulation of the tones. For many cases, the attenuations of the measured noise exceed the level of 15 dB, with maximum reduction reaching 31 dB. Also, the control process is demonstrated to be smoother and faster.

  19. Structural control of void formation in dual phase steels

    The objective of this study is to explore the void formation mechanisms and to clarify the influence of the hardness and structural parameters (volume fraction, size and morphology) of martensite particles on the void formation and mechanical properties in dual phase steels composed of ferrite...... and martensite. Two dual phase steels (Fe-0.099mass%C-1.63mass%Mn and Fe-0.148mass%-1.60mass%Mn) with martensite particles of different hardness values, volume fractions, sizes and shapes were produced by hot rolling and annealing. Mechanical properties were characterised by Vickers hardness and nanohardness...... particles but are not caused by the decohesion of martensite/ferrite interfaces. Three key factors that control the void formation behaviour in dual phase steels have been established: (i) a critical strain for void formation in the martensite, (ii) strain partitioning between the martensite and ferrite...

    2017-12-01

    An integrated research approach (remote sensing, field, geophysics) was conducted to investigate the structural control on groundwater flow in large aquifers using the less studied Nubian Sandstone Aquifer System (NSAS) of NE Africa as a test site. The aquifer extends over 2.2 x 106 km2 in Egypt, Libya, Chad, and Sudan and consists of thick (> 3 kms), water-bearing, Paleozoic and Mesozoic sandstone with intercalations of Tertiary shale and clay. It is subdivided into three sub-basins (Northern Sudan Platform [NSP], Dakhla [DAS], and Kufra) that are separated by basement uplifts (e.g., E-W trending Uweinat-Aswan uplift that separates DAS from the NSP). Aquifer recharge occurs in the south (NSP and southern Kufra) where the aquifer is unconfined and precipitation is high (Average Annual Precipitation [AAP]: 117 mm/yr.) and discharge is concentrated in the north (DAS and northern Kufra). Our approach is a three-fold exercise. Firstly, we compared GOCE-based Global Geopotential Models (GGMs) to terrestrial gravity anomalies for 21262 sites to select the optimum model for deriving Bouguer gravity anomalies. Secondly, structures and uplifts were mapped using hill shade images and their extension in the subsurface were mapped using the Eigen_6C4 model-derived Bouguer anomalies and their Tilt Derivative products (TDR). Thirdly, hydrological analysis was conducted using GRACE CSR 1° x 1° mascon solutions to investigate the mass variations in relation to the mapped structures. Our findings include: (1) The Eigen-6C4 is the optimum model having the lowest deviation (9.122 mGal) from the terrestrial gravity anomalies; (2) the surface expressions of structures matched fairly well with their postulated extensions in the subsurface; (3) identified fault systems include: Red Sea rift-related N-S to NW-SE trending grabens formed by reactivating basement structures during Red Sea opening and Syrian arc-related NE-SW trending dextral shear systems; (4) TWS patterns are uniform

    The focus of this paper is the question of legitimacy, and how can we consider legitimate an imposed constitution and the subsequent constitutional principles, practices and values that go hand-in-hand with the legal and political acculturation. Constitutional texts around the world are good...... examples of transposition and complicity of theological and juridical thoughts. For the purpose of this paper, imposed constitutions are political and legal norms of a state enacted and enforced without the free and full agreement of the Demos.

    Full Text Available In this work, active vibration control of an underwater cylindrical shell structure was investigated, to suppress structural vibration and structure-borne noise in water. Finite element modeling of the submerged cylindrical shell structure was developed, and experimentally evaluated. Modal reduction was conducted to obtain the reduced system equation for the active feedback control algorithm. Three Macro Fiber Composites (MFCs were used as actuators and sensors. One MFC was used as an exciter. The optimum control algorithm was designed based on the reduced system equations. The active control performance was then evaluated using the lab scale underwater cylindrical shell structure. Structural vibration and structure-borne noise of the underwater cylindrical shell structure were reduced significantly by activating the optimal controller associated with the MFC actuators. The results provide that active vibration control of the underwater structure is a useful means to reduce structure-borne noise in water.

    Active control of sound radiation from a vibrating rectangular plate by a steady-state harmonic point force disturbance is experimentally studied. Structural excitation is achieved by two piezoceramic actuators mounted on the panel. Two accelerometers are implemented as error sensors. Estimated radiated sound signals using vibro-acoustic path transfer function are used as error signals. The vibro-acoustic path transfer function represents system between accelerometers and microphones. The approach is based on a multi-channel filtered-x LMS algorithm. The results shows that attenuation of sound levels of 11dB, 10dB is achieved

    2013-07-01

    Full Text Available Resumo: O artigo pretende oferecer uma reinterpretação do debate tradicional sobre abstração da forma jurídica como dominação à luz da teoria dos sistemas de Niklas Luhmann. Para tanto, utiliza como pressuposto a releitura marxista do processo de diferenciação do direito oferecida por Raffaele de Giorgi no início dos anos 1980. Sustenta-se que o caráter complexo e contingente do sistema jurídico e do sistema social modernos exige, paradoxalmente, padrões e projetos de certeza que servem para ocultar ou conter a incerteza que os constitui. Dessa perspectiva, a noção luhmanniana de generalização de expectativas normativas é compreendida como a produção pelo direito de modelos abstratos de orientação que resistem a mudanças concretas, mas, ao mesmo tempo, submetem-se a seleções contingentes, necessárias para controlar eficazmente o elevado número de surpresas que uma sociedade sem fundamentos metafísicos pode produzir. Ao final, conclui-se que, a partir desta alternância contraditória e paradoxal entre certeza e incerteza, o direito torna-se um sistema moderno de controle da sociedade.   Palavras-chaves: Teoria dos sistemas; Abstração da forma jurídica como dominação; controle social; certeza e incerteza do direito. Abstract: The article intends to reinterpret the traditional debate on the abstraction of legal forms as domination in light of Niklas Luhmann’s systems theory. Therefore, it finds its presuppositions in the Marxist reading of differentiation of law as proposed by Raffaele de Giorgi in the beginning of the 1980’s. The article shows that the complexity and the contingency of modern social and legal systems paradoxically demands patterns and projects of certainty to hide or restraint the uncertainty they constitute themselves. In this sense the luhmannian notion of generalizing normative expectations is comprehended as the legal production of abstract models for guidance that resist concrete

    The SFTE project aims to establish a broad partnership between public and private entities to stimulate the economy and deliver between euros 180 bn and euros 420 bn of investment in Europe over 10 years for the benefit of medium-sized projects (in the order of euros 1 m) that are necessary for the energy transition. It will enable EU banks to finance the energy renovation of public buildings under excellent - cheap and long-term - conditions. A feasibility study has been conducted by the AFTER association with an exemplary consortium of public and private stakeholders in France: local authorities, industry players, banks/financial institutions, NGOs, Plan Batiment Durable. Many European institutions have expressed their interest in the initiative. Now the implementation of the SFTE project requires a commitment from European and national public authorities. Such a proactive real-estate policy would significantly contribute to economic recovery, cut costs, CO 2 emissions and the external deficit and improve energy independence, and could quickly create jobs. This document is the executive summary of the Operational feasibility study carried out from September 2013 to June 2014. It is followed by the SFTE project's legal structuring study carried out by the Association for the Financing of the Ecological Transition and Thermal Renovation (AFTER) working group

  12. Legal Deposit of Electronic Publications

    2009-06-01

    Full Text Available The most important and basic role of the deposition studies, which are the greatest contributions to the knowledge sharing, is to gather the artistic and philosophical works of a country and provide them for the use of future researchers. However, since early deposition studies were limited with printed publications, they do not involve the electronic publication types appearing with the development of information technology. This stems from the fact that the electronic publications require procedures different from those of the printed publications in terms of deposition steps because of their structures. Today, in order to guarantee that all registered cultural products, which are mostly produced and used in the electronic environment could be fully collected, electronic publications should also be covered by and regulated under legal deposit. This study analyzes the deposition of electronic publications, within the framework of their storage and protection, being put in the use of the users as well as the common approaches to deposition practices in the world parallel to the developments in the information technology. The related situation in Turkey was also evaluated.

  13. Englacial Structures as Indicators of the Controls on Ice Flow

    2015-12-01

    Direct sampling of the subglacial environment is costly, and will therefore never supply the spatial coverage needed to determine the basal boundary conditions required for large-scale ice-sheet modeling. Studies of the West Antarctic Ice Sheet (WAIS) show that the frictional and rheologic properties of the bed are a leading control on the evolution of the system, so developing geophysical methods to help constrain the basal characteristics of WAIS will reduce uncertainty in predictions of the timing and magnitude of future sea-level rise. Radar-imaged structures within the ice are an attractive data set for this pursuit, as they contain information about the flow dynamics that transform the horizontally deposited layers to their modern configuration; however, they can be challenging to interpret, given the number of processes acting to deform the internal layers and the difficulty in automating their analysis. In this study, we move away from the layer-tracing paradigm in favor of an automated slope extraction algorithm. This has several advantages: it does not require feature-continuity, providing a more stable result in regions of intense deformation, and it results in a data product that maps directly to model output. For steady-state features, layer slopes reflect the horizontal and vertical velocity structure, making quantitative comparison of the model and observations simple compared to the more qualitative, particle tracer comparisons done in the past. Using a higher order ice-flow model, we attempt to refine our understanding of basal properties using reflector slope fields at the grounding line of Whillans Ice Stream and the shear margin of the North East Greenland Ice Stream, with the hope of eventually using this method for basin-scale inversions.

    The 2006 Guinsaugon landslide in St. Bernard, Southern Leyte is one of the largest known landslides in the Philippines in recent history. It consists of a 15-20 million m3 rockslide-debris avalanche from an approximately 675 m high mountain weakened by continuous movement of the Philippine fault. The catastrophic Guinsaugon landslide killed 1221 people and displaced 19 000 residents over its 4.5 km path. To investigate the present day morphology of the scar and potential failure that may occur, analysis of a 5 m resolution IfSAR-derived Digital Elevation Model was conducted using Coltop3D and Matterocking software, leading to the generation of a landslide hazard map for the province of Southern Leyte in Central Philippines. The dip and dip-direction of discontinuity sets that contribute to gravitational failure in mountainous areas of the province were identified and measured using a lower Schmidt-Lambert color scheme. After measurement of the morpho-structural orientations, potential sites of failure were analyzed. Conefall was then utilized to compute the extent of rock mass runout. Results of the analysis show instability in the scarp area of the 2006 Guinsaugon landslide and in adjacent slopes because of the presence of steep discontinuities that range from 45-60°. Apart from the 2006 Guinsaugon landslide site, runout models simulated farther rock mass extent in its adjacent slopes, revealing a high potential for fatal landslides to happen in the municipality of St. Bernard. Concerned agencies may use maps produced in the same manner as this study to identify possible sites where structurally-controlled landslides can occur. In a country like the Philippines, where fractures and faults are common, this type of simulated hazard maps would be useful for disaster prevention and facilitate disaster risk reduction efforts for landslide-susceptible areas.

    Voluntary active euthanasia for adults at their explicit request has been legal in Belgium and the Netherlands since 2002. In those countries, acceptance of the practice for adults has been followed by acceptance of the practice for children. Opponents of euthanasia see this as a dangerous slippery slope. Proponents argue that euthanasia is sometimes ethically appropriate for minors and that, with proper safeguards, it should be legally available in appropriate circumstances for patients at any age. In this Ethics Rounds, we asked philosophers from the United States and the Netherlands, and a Dutch pediatrician, to discuss the ethics of legalizing euthanasia for children.

    This article describes the findings of a descriptive analysis of 27 online drug retailers selling legal alternatives to illegal drugs, commonly referred to as "herbal highs" and "legal highs" in 2008 . The study attempted to quantify the online availability of drug retailers, to describe common products and characteristics in EU-based retail sales. The findings highlight the concern about the lack of objective information about products offered, including potential risks to health. Systems should be developed to assess the contents of products and the accuracy of information provided on the Internet, alongside continued monitoring of this market for "legal high" substances.

  18. Improving substructure identification accuracy of shear structures using virtual control system

    Science.gov (United States)

    Zhang, Dongyu; Yang, Yang; Wang, Tingqiang; Li, Hui

    2018-02-01

    Substructure identification is a powerful tool to identify the parameters of a complex structure. Previously, the authors developed an inductive substructure identification method for shear structures. The identification error analysis showed that the identification accuracy of this method is significantly influenced by the magnitudes of two key structural responses near a certain frequency; if these responses are unfavorable, the method cannot provide accurate estimation results. In this paper, a novel method is proposed to improve the substructure identification accuracy by introducing a virtual control system (VCS) into the structure. A virtual control system is a self-balanced system, which consists of some control devices and a set of self-balanced forces. The self-balanced forces counterbalance the forces that the control devices apply on the structure. The control devices are combined with the structure to form a controlled structure used to replace the original structure in the substructure identification; and the self-balance forces are treated as known external excitations to the controlled structure. By optimally tuning the VCS’s parameters, the dynamic characteristics of the controlled structure can be changed such that the original structural responses become more favorable for the substructure identification and, thus, the identification accuracy is improved. A numerical example of 6-story shear structure is utilized to verify the effectiveness of the VCS based controlled substructure identification method. Finally, shake table tests are conducted on a 3-story structural model to verify the efficacy of the VCS to enhance the identification accuracy of the structural parameters.

    The legal provisions governing the acknowledgment of test results are most frequently applied by administrative orders (design and qualification approvals or specimen testing and approval) and are thus claimable and voidable in accordance with general administrative law. The acknowledgment of test certificates requires a legal basis. Test results, however, can be acknowledged also by administrative bodies. Recently, the Federal Government began to delegate more of its legal authority in this field to private institutions, allowing test results to be acknowledged and test certificates to be issued by government controlled private institutions.

    The legal provisions governing the acknowledgment of test results are most frequently applied by administrative orders (design and qualification approvals or specimen testing and approval) and are thus claimable and voidable in accordance with general administrative law. The acknowledgment of test certificates requires a legal basis. Test results, however, can be acknowledged also by administrative bodies. Recently, the Federal Government began to delegate more of its legal authority in this field to private institutions, allowing test results to be acknowledged and test certificates to be issued by government controlled private institutions.

  2. Legal Aspects of Telepathology

    2000-01-01

    Full Text Available In some legal surroundings telepathology is considered a breach of registrational barriers. The recommendation of the G 8 states in Europe for required legislation in telemedicine suggests to recognise that the localization of the remote health care professional defines the site not only of licensure but also of liability. This approach must be considered helpful, since it can solve many problems brought about by the doubtful results of private international law and conventions like the European Union (EU and Lugano Convention. Under today's conditions in private international law it must be considered essential to agree upon a choice of law and stipulate a court of jurisdiction when doing telepathology. However, the opposing aims of insuring the patients claims and avoiding jurisdictions that exceed the local expectations of the medical professional must be reconciled. Data protection and data security are other crucial topics that require attention. Generally speaking, the principles of minimum data exchange, anonymity, pseudonymity and cryptography must be established as a basis for all telepathology procedures. Only when personal data is needed, its use can be legitimated. Written consent of the patient is advised. To guarantee a cross‐border security level the regulations of the EU‐Data Protection Directive need to be transformed into national law. In practise, cross‐border dataflow shall only take place where the security level can be maintained even within the other country. Finally, reimbursement questions must be answered to establish a sound economical basis for telepathology. The spatial distance between the participants may yield the question, whether the service has been rendered to an extent necessary and sufficient for reimbursement. If reimbursement takes place on a cross‐border or cross‐regional level, severe disturbances of the health systems can occur. Regulation schemes or treaties need therefore to be developed to

    One-dimensional SnO(2) nanomaterials with wide bandgap characteristics are attractive for flexible and/or transparent displays and high-performance nano-electronics. In this study, the crystallinity of SnO(2) nanowires was regulated by controlling their growth temperatures. Moreover, the correlation of the crystallinity of nanowires with optical and electrical characteristics was analyzed. When SnO(2) nanowires were grown at temperatures below 900 °C, they showed various growth directions and abnormal discontinuity in their crystal structures. On the other hand, most nanowires grown at 950 °C exhibited a regular growth trend in the direction of [100]. In addition, the low temperature photoluminescence measurement revealed that the higher growth temperatures of nanowires gradually decreased the 500 nm peak rather than the 620 nm peak. The former peak is derived from the surface defect related to the shallow energy level and affects nanowire surface states. Owing to crystallinity and defects, the threshold voltage range (maximum-minimum) of SnO(2) nanowire transistors was 1.5 V at 850 °C, 1.1 V at 900 °C, and 0.5 V at 950 °C, with dispersion characteristics dramatically decreased. This study successfully demonstrated the effects of nanowire crystallinity on optical and electrical characteristics. It also suggested that the optical and electrical characteristics of nanowire transistors could be regulated by controlling their growth temperatures in the course of producing SnO(2) nanowires.

    Full Text Available One of the distinguishing features of man as a biological individual who is able to comprehend meaningfully the reality surrounding him and manage his actions is consciousness. Depending on the scientific-theoretical approaches or applied needs, it is customary to apply a certain differentiation of definitions of the concept of consciousness, for example, everyday or political, individual or mass, the consciousness of school or student youth, and other. One of its varieties, perhaps the most important at the present stage of development of society and statehood, is the legal consciousness of man. The problem of the formation and functioning of the human sense of justice is one of the most popular and constantly developed in a number of scientific fields. The purpose of the work is to study the state of scientific knowledge of the legal consciousness and legal culture of student, future pharmacists in the context of legal education in the university. Materials and methods. According to a specific goal, the research was based on the analysis of international and national legislation, the database of scientific research developments of the National Library of Ukraine V.I.

  6. Quasicanonical structure of optimal control in constrained discrete systems

    Sieniutycz, S.

    2003-06-01

    This paper considers discrete processes governed by difference rather than differential equations for the state transformation. The basic question asked is if and when Hamiltonian canonical structures are possible in optimal discrete systems. Considering constrained discrete control, general optimization algorithms are derived that constitute suitable theoretical and computational tools when evaluating extremum properties of constrained physical models. The mathematical basis of the general theory is the Bellman method of dynamic programming (DP) and its extension in the form of the so-called Carathéodory-Boltyanski (CB) stage criterion which allows a variation of the terminal state that is otherwise fixed in the Bellman's method. Two relatively unknown, powerful optimization algorithms are obtained: an unconventional discrete formalism of optimization based on a Hamiltonian for multistage systems with unconstrained intervals of holdup time, and the time interval constrained extension of the formalism. These results are general; namely, one arrives at: the discrete canonical Hamilton equations, maximum principles, and (at the continuous limit of processes with free intervals of time) the classical Hamilton-Jacobi theory along with all basic results of variational calculus. Vast spectrum of applications of the theory is briefly discussed.

  7. Structural controls on anomalous transport in fractured porous rock

    Edery, Yaniv; Geiger, Sebastian; Berkowitz, Brian

    2016-07-01

    Anomalous transport is ubiquitous in a wide range of disordered systems, notably in fractured porous formations. We quantitatively identify the structural controls on anomalous tracer transport in a model of a real fractured geological formation that was mapped in an outcrop. The transport, determined by a continuum scale mathematical model, is characterized by breakthrough curves (BTCs) that document anomalous (or "non-Fickian") transport, which is accounted for by a power law distribution of local transition times ψ>(t>) within the framework of a continuous time random walk (CTRW). We show that the determination of ψ>(t>) is related to fractures aligned approximately with the macroscopic direction of flow. We establish the dominant role of fracture alignment and assess the statistics of these fractures by determining a concentration-visitation weighted residence time histogram. We then convert the histogram to a probability density function (pdf) that coincides with the CTRW ψ>(t>) and hence anomalous transport. We show that the permeability of the geological formation hosting the fracture network has a limited effect on the anomalous nature of the transport; rather, it is the fractures transverse to the flow direction that play the major role in forming the long BTC tail associated with anomalous transport. This is a remarkable result, given the complexity of the flow field statistics as captured by concentration transitions.

  11. [Synthetic cannabinoids--the new "legal high" drugs].

    Science.gov (United States)

    Berkovitz, Ronny; Arieli, Mickey; Marom, Eli

    2011-12-01

    Recently, a new Law, named the "derivative law" (first addition, schedule drug change--2010), was accepted in the Israeli parliament. It will mean that dangerous substances that are closely related structurally to a drug that is listed in the dangerous drugs ordinance will automatically enter the dangerous drugs ordinance. The dangerous drugs that were sold in kiosks were related to 4 major groups: Amphetamines, methamphetamines, cathinone and methcathinone. Over 90% of the substances known as "legal highs" or "hagigat" belong to these groups. Before the law was accepted, merchandisers and clandestine Laboratories took advantage of a state in which every small molecular change in a controlled substance of amphetamines, methamphetamines, cathinone and methcathinone required a long legal process in order to include the new substance in the controlled substance law. During this process, we believe that public health was endangered. The chemists and merchandisers found a new solution to "legally" bypass the "derivative law", by marketing a new group of substances named "synthetic cannabinoids". The synthetic cannabinoids do not resemble the chemical structure of tetrahydrocannabinol (THC] which appears in marijuana or hashish, but affects the body in the same manner and according to the literature, are five times more potent. The synthetic cannabinoids are sold in Israel under different nicknames such as: "Mabsuton", "Mr. Nice Guy", "Spice", "Sabbaba" and "Lemon Grass". The substance can be used in different ways such as smoking, inhaling or swallowing. The use of synthetic cannabinoids causes side effects that include: euphoria, dizziness, headache, thirst, paranoia, insomnia, fatigue and disturbed vision. Cases of hospital admission in Israel due to the use of these substances have been reported. The symptoms included psychiatric disturbances. In an urgent meeting of the multi-ministry committee on psychotropic substances held in December 2010 in the Israel Anti

  16. The legacy of legal culture and Serbia's European integration

    Directory of Open Access Journals (Sweden)

    Kovačević Slaviša

    2014-01-01

    Full Text Available In the context of the EU integration, it is certainly insufficient to harmonize only the positive law and the institutional regulatory framework. In order to provide for the implementation and application of the positive law, the political and legal culture must be congruent with the legal tradition of the European Union. The 'implantation' of legal institutes is a fashionable trend common to all transition countries, which fail to recognize a significant and inevitable fact that law is created and applied in the country-specific traditional, cultural and social context. Legal norms achieve their intended purpose only when they are reinforced by a number of other traditional, cultural, political, economic, and social circumstances. Hence, there is a specific functional and structural relation between law and social culture: on the one hand, law is the product of society; on the other hand, law is also the creator of social norms. Consequently, instead of 'copying' the legal norms of the European Union, it is necessary to create a social framework for the implementation of applicable, effective and equitable EU law. In addition to nomotechnics, scientific research on the 'harmonization of Serbian law with the EU law shall include the analysis of other factors, which are only apparently outside the legal framework but which are important for the general outcome of this process. Our legal culture is largely authoritarian, which is evident in the prevalence of power in the process of making and applying the law and in the dependence of the judicial system from the executive branch of government. Law is an instrument of political power of the legally unaccountable executive branch of government. The authoritarian legal rules are not an expression of reason, prudence, wisdom and general public interest but a temporary constellation of interests of power-holders while the normative activity is a short-term tactics for accomplishing these interests.

  17. Nonlinear phononics and structural control of strongly correlated materials

    2016-01-20

    Mid-infrared light pulses can be used to resonantly excite infrared-active vibrational modes for the phase control of strongly correlated materials on subpicosecond timescales. As the energy is transferred directly into atomic motions, dissipation into the electronic system is reduced, allowing for the emergence of unusual low energy collective properties. Light-induced superconductivity, insulator-metal transitions and melting of magnetic order demonstrate the potential of this method. An understanding of the mechanism, by which these transitions are driven, is however missing. The aim of this work is to uncover this process by investigating the nonlinear lattice dynamics induced by the excitation and to elucidate their contribution to the modulation of collective properties of strongly correlated materials. The first signature of nonlinear lattice dynamics was reported in the observation of coherent phonon oscillations, resonant with the excitation of an infrared-active phonon mode in a manganite. This nonlinear phononic coupling can be described within a model, which predicts not only oscillatory coherent phonons dynamics but also directional atomic displacements along the coupled modes on average, which could cause the previously observed transitions. We verified this directional response and quantified the anharmonic coupling constant by tracing the atomic motions in a time-resolved hard X-ray diffraction experiment with sub-picometer spatial and femtosecond temporal resolution. In a subsequent study, we investigated the role of nonlinear lattice dynamics in the emergence of superconductivity far above the equilibrium transition temperature, an intriguing effect found to follow lattice excitation of YBa{sub 2}Cu{sub 3}O{sub 6+x}. By combining density functional theory (DFT) calculations of the anharmonic coupling constants with time-resolved X-ray diffraction experiments, we identified a structural rearrangement, which appears and decays with the same temporal

    It is known that radon gas is not generally considered to be a major problem when encountered in the working environment. However, in its process of decay, a series of four short lived daughter products are formed. In a dust-laden atmosphere these daughter products, which are ionized readily, attach to the particulate material and when inhaled are deposited in the alveoli of the lungs. Therefore, if respirable dust is controlled, the effects of radon daughters will also be minimized. The legal requirements for dust control in South Africa and their implications are discussed. 1 ill

  1. A Goddess for semiotics of law and legal discourse

    Jan M. Broekman

    2011-12-01

    Full Text Available The work of the great American philosopher Charles Sanders Peirce (1839-1914 becomes more and more appreciated beyond the boundaries of his pragmatism, a philosophical mainstream he founded in the early 20th century. This essay is inspired by five points of interest, all of which focus on law and legal discourse. Firstly, one should acknowledge that his proposal pertaining to a general theory of signs, which he called ‘semeiotics’ around 1860, leads to an untraditional and in-depth understanding of legal discourse: in essence, of law as a system of specific meanings and signs. Semiotics in general became a substantial part of his ‘evolutionary cosmology,’ an all-embracing approach to tackle classical and modern philosophical issues. Secondly, his anthropological intuition based on semiotics, (concentrated in the formula ‘man is a sign’ became important for our understanding of a human subject’s position in law, as author of a legal discourse as well as an individual subjected to law. Thirdly, the tensions between chance and continuity in legal discourse are of focal interest for the creation of legal meaning in law’s practices. Novelty, Peirce suggested in this context, occurs by the grace of chance rather than of continuity and fixed traditions. Fourthly, Roberta Kevelson (1931-1998 explored and expanded the field of legal semiotics on the basis of the works of Peirce. In doing so, she established an American tradition of legal semiotics distinct from a European tradition, which related more to linguists, psychologists and philosophers embracing structuralism. Fifthly, Tyche, the Ancient Goddess of fate and fortune, is because of Peirce’s references more at home in the US legal semiotic tradition. Her fame and influence reaches beyond law and became supported by recent archaeological discoveries, publications and exhibitions, which not only provide information about her background, but also underline her possible influence on

    2014-06-01

    Full Text Available The legal evaluation of the penalty interest, meaning the ex lege determination of its level is applicable only in the case of non-fulfillment of a monetary payment obligation. The applicability of the system of legal evaluation of the interest is generally determined by the absence of a document that ascertains the agreement of the parties, such as a contract, through which the parties, following this agreement, evaluate the prejudice caused by the non-fulfillment of a monetary payment obligation, before the prejudice has occurred. The legal evaluation of the penalty interest, as a component of the regulation in the field of legal interest has the purpose to ensure creditor’s protection. Regardless of the prejudice caused to the creditor, the legal penalty interest shall be determined by relating it to a variable benchmark that is the level of the reference interest rate of the National Bank of Romania, which is the monetary policy interest rate of the National Bank of Romania.

In article are characterized by individual patterns of legal socialization of a personality, revealing its essence, on the basis of summarizing opinions of scientists based on their own point of view. On the basis of the theoretical analysis made assumptions about the peculiarities of legal socialization of the individual occurring in different age periods of life; formulated likely areas for further study the phenomenon under research legal psychology.

  4. Vibration suppression control of smart piezoelectric rotating truss structure by parallel neuro-fuzzy control with genetic algorithm tuning

    Science.gov (United States)

    Lin, J.; Zheng, Y. B.

    2012-07-01

    The main goal of this paper is to develop a novel approach for vibration control on a piezoelectric rotating truss structure. This study will analyze the dynamics and control of a flexible structure system with multiple degrees of freedom, represented in this research as a clamped-free-free-free truss type plate rotated by motors. The controller has two separate feedback loops for tracking and damping, and the vibration suppression controller is independent of position tracking control. In addition to stabilizing the actual system, the proposed proportional-derivative (PD) control, based on genetic algorithm (GA) to seek the primary optimal control gain, must supplement a fuzzy control law to ensure a stable nonlinear system. This is done by using an intelligent fuzzy controller based on adaptive neuro-fuzzy inference system (ANFIS) with GA tuning to increase the efficiency of fuzzy control. The PD controller, in its assisting role, easily stabilized the linear system. The fuzzy controller rule base was then constructed based on PD performance-related knowledge. Experimental validation for such a structure demonstrates the effectiveness of the proposed controller. The broad range of problems discussed in this research will be found useful in civil, mechanical, and aerospace engineering, for flexible structures with multiple degree-of-freedom motion.

    The basic theory is presented for the geometry, stiffness, and damping control of adaptive structures, with emphasis on adaptive truss structures. Necessary and sufficient conditions are given for stress-free geometry control in statically determinate and indeterminate adaptive discrete structures. Two criteria for selecting the controls are proposed, and their use in real-time control is illustrated by numerical simulation results. It is shown that the stiffness and damping control of adaptive truss structures for vibration suppression is possible by elongation and elongation rate dependent feedback forces from the active elements.

    2010-12-01

    The goal of this article is to discuss the legal pitfalls that reproductive endocrinologists face when participating in gestational surrogacy contracts. This paper was composed using Westlaw and LexisNexis commercial legal search engines to perform a review of statutes and cases pertaining to gestational surrogacy. The search results demonstrated that in the absence of suitable preparation, there is significant potential for litigation while participating in gestational agreements. Providers caring for gestational carriers have been named as parties in lawsuits for failure to provide psychological screening, failure to screen for infectious disease and participation in gestational contracts that are not compliant with state law. There is great disparity in state laws and court rulings pertaining to gestational agreements. When legal disputes arise, individual state laws and court rulings are controlling over the Uniform Parentage Act. Likewise, recommendations by the American College of Obstetricians and Gynecologists and the American Society for Reproductive Medicine do not supersede state laws. The failure to abide by individual state laws unnecessarily exposes reproductive endocrinologists and their IVF facilities to potential litigation. In order to lessen exposure to litigation, an understanding of individual state legislation or historical court rulings is advised. Copyright © 2010 Reproductive Healthcare Ltd.

    Full Text Available Legal entities play an increasing role in international economic relations, as well as in political, cultural, social or human relations. Any legal entity is subject to the law of a certain country, as it can only exist or function on the basis of legal provisions. In this sense, the paper analyses the law applicable to the organic statute of a legal entity, the importance and criteria underlying the establishment of a legal entity’s nationality, the recognition of foreign legal entities in Romania, as well as the rights and obligations of foreign legal entities residing in our country.

  14. Do organizational and political-legal arrangements explain financial wrongdoing?

    Prechel, Harland; Zheng, Lu

    The 2008 financial crisis was a systemic problem with deep-rooted structural causes that created opportunities to engage in financial malfeasance, a form of corporate wrongdoing. However, few quantitative studies exist on the effects of organizational and political-legal arrangements on financial malfeasance. In this paper, we examine the effects of organizational and political-legal arrangements that emerged in the 1990s in the FIRE sector (i.e., financial, insurance, and real estate) on financial malfeasance. Our historical contextualization demonstrates how changes in the political-legal arrangements facilitate the emergence of new corporate structures and opportunities for financial malfeasance. Our longitudinal quantitative analysis demonstrates that US FIRE sector corporations with a more complex organizational structure, larger size, lower dividend payment, and higher executive compensation are more prone to commit financial malfeasance. © London School of Economics and Political Science 2016.

    We consider the effect of legal access to alcohol on student achievement. Our preferred approach identifies the effect through changes in one's performance after gaining legal access to alcohol, controlling flexibly for the expected evolution of grades as one makes progress towards their degree. We also report RD-based estimates but argue that an RD design is not well suited to the research question in our setting. We find that students' grades fall below their expected levels upon being able to drink legally, but by less than previously documented. We also show that there are effects on women and that the effects are persistent. Using the 1997 National Longitudinal Survey of Youth, we show that students drink more often after legal access but do not consume more drinks on days on which they drink.

    2012-01-01

    In general, mechanical equipment such as cars, airplanes, and machine tools all operate with constant frequency characteristics. These constant working characteristics should be controlled if the dynamic performance of the equipment demands improvement or the dynamic characteristics is intended to change with different working conditions. Active control is a stable and beneficial method for this, but current active control methods mainly focus on vibration control for reducing the vibration amplitudes in the time domain or frequency domain. In this paper, a new method of dynamic frequency characteristics active control (DFCAC) is presented for a flat plate, which can not only accomplish vibration control but also arbitrarily change the dynamic characteristics of the equipment. The proposed DFCAC algorithm is based on a neural network including two parts of the identification implement and the controller. The effectiveness of the DFCAC method is verified by several simulation and experiments, which provide desirable results.

  17. The Legal Regulation of Cybersecurity

    2013-08-01

    Full Text Available Cybercrime has become a global phenomenon, which is causing more harm to individual citizens, organizations, society and the state. Most countries in the world compare cybercrime with offences such as terrorism and drug trafficking due to its risks and profitability. Cybersecurity is the central category to fight cybercrime in cyberspace. Therefore, the strategic legal regulation of cybersecurity is one of the most relevant problems in EU, including Lithuania. So far cybersecurity legal regulation analysis in scientific literature has been rather limited. The European Commission, together with the High Representative of the Union for Foreign Affairs and Security Policy, has published a cybersecurity strategy alongside a Commission proposed directive on network and information security (NIS. The cybersecurity strategy – “An Open, Safe and Secure Cyberspace” - represents the EU’s comprehensive vision on how best to prevent and respond to cyber disruptions and attacks. The purpose of its is to further European values of freedom and democracy and ensure the digital economy can safely grow. Specific actions are aimed at enhancing cyber resilience of information systems, reducing cybercrime and strengthening EU international cyber-security policy and cyber defence. The main goal of the paper is to analyze and compare the EU cybersecurity strategy and experience of several foreign countries with the strategic legal regulation of cybersecurity in Lithuania. The article consists of four parts. The first part dealt with the EU cybersecurity strategy. The second part of the article examines the comparative aspect of foreign cybersecurity strategic legal regulation. The third part deals with attempts in Lithuania to draft cybersecurity law and the holistic approach of cybersecurity legal regulation. The fourth part examines Lithuanian cybersecurity strategy and comments on the main probleas related with the strategy. Several different approaches

  18. Long-term behaviour of timber structures in torrent control

    2014-05-01

    Timber is widely used for protection measures in torrent control. However, life span of woody constructions such as timber check dams is limited due to fungal decay. However, only sparse scientific information is available on the long-term behaviour of timber structures and the colonisation with decay fungi. Related to this, in practice a controversial discussion has been going on if either Norway Spruce (Picea abies) or Silver Fir (Abies alba) is more enduring and if bark removal increases resistance against fungal decay. In order to going into this matter a series of 15 timber check dams built in 1996 has been monitored. The constructions were alternatively realised with Norway Spruce and Silver Fir, half of them each with remaining and removed bark, respectively. The scientific investigations included the documentation of colonisation with rot fungi and the identification of decayed zones with a simple practical approach as well as based on drilling resistance. Colonisation by decay fungi started three years after construction (e.g. Gloeophyllum sepiarium), detecting two years later first parts with reduced wood resistance. Sixteen years after construction decay was found on all check dams but two. Wood quality was markedly better in watered sections compared to the occasionally dry lateral abutment sections. Taking the whole check dams into consideration, slightly more decay was detected in Norway Spruce compared to logs in Silver Fir and both the practical approach and the drilling resistance measurement yielded in more defects on logs without bark. However, due to limited number of replications and fungal data, it was not possible to statistically verify these results. Statistical analysis was restricted to the drilling resistance data and fruit-bodies of decay fungi of the uppermost log of each check dam. Based on this limited analysis significant differences in the effect on the drilling resistance were found for watered sections and lateral abutments

  19. Structural controls and mechanisms of diffusion in natural silicate melts

    Henderson, P.; Nolan, J.; Cunningham, G. C.; Lowry, R. K.

    1985-04-01

    The diffusion properties of Na, Cs, Ba, Fe and Eu ions have been determined experimentally for a pantellerite melt and of these ions plus Li, Mn and Co in pitchstone melt, using the radiotracer residual-activity method, and narrow platinum capillaries, over the temperature range 1,200 1,400° C. In addition, Eu diffusion in a basaltic and an andesitic melt was determined. Diffusion of all cations follows an Arrhenius relationship, activation energy values being high for diffusion in the pantellerite melt (e.g. Eu: 100 kcal mol-1) except in the case of Na (24.3 kcal mol-1). Activation energies of diffusion in the pitchstone melt are similar to values recorded earlier for andesitic and basaltic melts. The new data are used, along with previously published data for diffusion in other composition melts, to examine the compositional and structural controls on diffusion. The range of diffusivities shows a marked change with melt composition; over two orders of magnitude for a basaltic melt, and nearly four orders for a pantellerite melt (both at 1,300° C). Diffusivity of all cations (except Li and Na) correlates positively with the proportion of network modifying cations. In the case of Li and Na the correlation is negative but the diffusivity of these ions correlates positively with the proportion of Na or of Na + K ions in the bulk melt. Diffusion behaviour in the pantellerite melt departs from the relationships shown by the data for other melt compositions, which could be partly explained by trivalent ions (such as Fe) occupying network forming positions. The diffusivity of alkali metal ions is strongly dependent on ionic radius, but this is not the case with the divalent and trivalent ions; diffusivity of these ions remains relatively constant with change in radius but decreases with increase in ionic charge. A compensation diagram shows four distinct but parallel trends for the majority of the cations in four melt types but the data for Li and Na plot on a separate

    PID controllers are frequently used to control systems requiring zero steady-state error while maintaining requirements for settling time and robustness (gain/phase margins). PID controllers suffer significant loss of performance due to short-term integrator wind-up when used in systems with actuator saturation. We examine several existing and proposed methods for the prevention of integrator wind-up in both continuous and discrete time implementations.

    The 52nd German Lawyers Meeting will be concerned in its legal department with the question of whether, from the points of view of the guaranteeing of the necessary environmental protection, additional regulations in the administrative procedures and administrative legal rights should be recommended. Here one is concerned, above all, with the problem of whether an administrative legal associations sueing or associations participation in administrative legal procedures is desirable in the interests of environmental protection. A negative answer must be given to this question. Discussion should concentrate on the problematical administrative legal interests, on the strengthening of administrative participation of popular opinion or interests in legal processes, on other improvements in administrative processes and on the legal control by Parliament of environmental protection.

    1981-01-01

    The legal basis for the use of nuclear energy is generally given by an Atomic Energy Act. Additionally, however, a system of regulations and standards has to be set up to lay down more detailed requirements. The fundamental philosophy and strategy has to be specified by governmental organizations. For the specification and implementation of the requirements some minimum organizational arrangements are necessary, which are not only restricted to governmental organizations. Furthermore procedural regulations have to be laid down before the implementation phase. This includes aspects like public participation in the licensing procedure. In practice, however, the implementation of the legal requirements always shows some weakness of the basic legal requirements. To learn from this experience some examples are presented, which gave rise to difficulties in the implementation procedure. (orig./RW)

  10. Control of framed structures using intelligent monitoring networks

    Directory of Open Access Journals (Sweden)

    Foti Dora

    2017-01-01

    Full Text Available The paper proposes the integration of structural monitoring with Building Management Systems for electricity and gas distributions. To assess the state of damage of existing buildings the technics of Structural Health Monitoring (SHM is adopted. SHM as well as to record the occurrence of sudden structural damage resulting from exceptional events (earthquakes, explosions, shocks and collisions with vehicles, etc., allows the monitoring of the progressive damage and structural performance under operating conditions through the extraction of the modal parameters of the structure. This approach requires time to process acquired data that, depending on the size of the building and the number of monitored points, varies from minutes to hours. In this paper, an intelligent system is proposed to immediately communicate during an earthquake the overrun of a certain ground shaking threshold so that gas delivery and selected power loads are interrupted, as suggested by current national regulations on structures. The use of low-cost and reduced size accelerometric sensors integrated with Energy Monitoring Systems is proposed in both highrisk earthquake centers and in all “strategic” buildings that must ensure their operation use immediately after the earthquake. The procedure for calibrating the horizontal and vertical acceleration threshold is also sketched.

    The scope of this thesis is the simulation of the dynamics of complex rigid multi-body systems involved in robotics, in order to control them. In the first stage, methods for obtaining equations and models required for simulation and control purposes are proposed and discussed: - determination of constraint equations using the jacobian matrices, - elaboration of direct and inverse dynamics of manipulators. The second part of this thesis deals with the different concepts and components involved in the setting of simulation systems for Robotics Application Programs: models, emulators and the software development environment. The control algorithms are then introduced as a particular class of robotics application programs. A simulator has been developed, allowing the calculation and the visualisation of robot motions, driven by generalized torques. Some examples of control programs generating such control torques are then presented to illustrate the use of the simulator. (author) [fr

    Vector control methods offer the possibility to gain high performance, being widely used. Certain applications require an optimum control in limit operating conditions, as, at maximum torque, that is not always satisfied. The paper presents how the voltage and the frequency for an asynchronous machine (ASM) operating at variable speed are determinate, with an accent on the method that keeps the rotor flux constant. The simulation analyses consider three load types: variable torque and speed, variable torque and constant speed, constant torque and variable speed. The final values of frequency and voltage are obtained through the proposed control schemes with one controller using the simulation language based on the Maple module. The dynamic analysis of the system is done for the case with P and PI controller and allows conclusions on the proposed method, which can have different applications, as the ASM in wind turbines.

    An overview of those legal areas which directly affect technical and planning decisions is presented in the form of 2 legal approaches which constrain the indiscriminate release of thermal discharges to receiving waters. One takes the form of private remedies which have traditionally been available to aggrieved parties who are in some way damaged by the harmful discharge. The 2nd approach utilizes the various statutory constraints leading to direct governmental action. It appears that statutory law is playing the prominent role in restricting the temperature to which receiving waters may be raised as a result of such discharges by using effluent limitations and water quality standards.

    Health disparities among low-income individuals remain a significant problem. A number of social determinants are associated with adverse health outcomes. Medical-legal partnerships address legal concerns of low-income individuals to improve health and wellness in adults and children. The Medical-Legal Partnership at Legal Aid of Western Missouri provides free direct legal services for patients with legal concerns affecting health. There is limited evidence regarding the association between advocacy-related efforts and changes within both the medical-legal partnership structure and in health-care facilities. Three health-care organizations in Kansas City, MO participated in implementing the medical-legal partnership model between 2007 and 2010. Advocacy efforts conducted by key medical-legal partnership personnel were strongly associated with changes in health-care organizations and within the medical-legal partnership structure. This study extends the current evidence base by examining the types of advocacy efforts required to bring about community and organizational changes.

    Full Text Available The aim of the article is a comparative analysis of the administrative and legal regulation of tax administration in European countries and in Ukraine and the definition of ways to improve domestic legislation in this field on this basis. The subject of the study is the administrative and legal principles of tax administration in the conditions of decentralization of state power. Methodology. The study is based on a comparison of the foreign experience of legal regulation and collection of local taxes by using the example of European states with the current state of the process of introducing tax decentralization in Ukraine. Due to the use of this amount of general scientific and specialscientific methods and methods of scientific knowledge, the content of the administrative and legal foundations of tax administration, as well as legal phenomena such as tax decentralization, were characterized and defined. The conclusions that we made helped us to determine the specifics of their administrative-legal regulation in some countries of Europe and in Ukraine. The results of the conducted comparative legal study made it possible to prove the direct impact of tax decentralization on the mechanism of tax administration and the systematic organization of tax authorities. These processes have a predominantly positive impact on macroeconomic processes, they broaden the rights and opportunities of local authorities regarding the use of funds by local governments, forecasting and approving regional budgets, and managing taxes and fees. Practical impact. The administration of taxes in the conditions of decentralization in Europe can be characterized by a high level of efficiency and functionality of the work of the territorial tax-control bodies. This experience is really necessary for Ukraine, where the activities of local self-government in some areas are limited by the central apparatus. Value/originality.

    Full Text Available This paper presents an adaptive functional-based Neuro-fuzzy-PID incremental (NFPID controller structure that can be tuned either offline or online according to required controller performance. First, differential membership functions are used to represent the fuzzy membership functions of the input-output space of the three term controller. Second, controller rules are generated based on the discrete proportional, derivative, and integral function for the fuzzy space. Finally, a fully differentiable fuzzy neural network is constructed to represent the developed controller for either offline or online controller parameter adaptation.  Two different adaptation methods are used for controller tuning, offline method based on controller transient performance cost function optimization using Bees Algorithm, and online method based on tracking error minimization using back-propagation with momentum algorithm. The proposed control system was tested to show the validity of the controller structure over a fixed PID controller gains to control SCARA type robot arm.

    Full Text Available Acoustic and vibration control for an underwater structure under mechanical excitation has been investigated by using negative feedback control algorithm. The underwater structure is modeled with cylindrical shells, conical shells, and circular bulkheads, of which the motion equations are built with the variational approach, respectively. Acoustic property is analyzed by the Helmholtz integration formulation with boundary element method. Based on negative feedback control algorithm, a control loop with a coupling use of piezoelectric sensor and actuator is built, and accordingly some numerical examples are carried out on active control of structural vibration and acoustic response. Effects of geometrical and material parameters on acoustic and vibration properties are investigated and discussed.

    Future High Energy Physics experiments require the use of light and stable structures to support their most precise radiation detection elements. These large structures must be light, highly stable, stiff and radiation tolerant in an environment where external vibrations, high radiation levels, material aging, temperature and humidity gradients are not negligible. Unforeseen factors and the unknown result of the coupling of environmental conditions, together with external vibrations, may affect the position stability of the detectors and their support structures compromising their physics performance. Careful optimization of static and dynamic behavior must be an essential part of the engineering design. Genetic Algorithms ( GA) belong to the group of probabilistic algorithms, combining elements of direct and stochastic search. They are more robust than existing directed search methods with the advantage of maintaining a population of potential solutions. There is a class of optimization problems for which Ge...

    Schweigert, I. V.; Keidar, M.

    2017-06-01

    The characteristics of two-dimensional periodical structures in a magnetized plasma are studied using kinetic simulations. Ridges (i.e. spikes in electron and ion density) are formed and became more pronounced with an increase of magnetic field incidence angle in the plasma volume in the cylindrical chamber. These ridges are shifted relative to each other, which results in the formation of a two-dimensional double-layer structure. Depending on Larmor radius and Debye length up to 19 potential steps appear across the oblique magnetic field. The electrical current gathered into the channels is associated with the electron and ion density ridges.

    ‘Justice’, philosophically, is classified into two; legal justice and social justice. Legal justice refers to justice based on the parameters of the rules while social justice may be defined as equality arises from human relation in the existing social structure. Referring to the implementation of the law nowadays, it is likely that justice cannot be achieved by looking only at the legal justice. Providing justice should also count on the aspect of social justice. Most of the time, the proble...

  14. International acceptance of irradiated food. Legal aspects

    International Nuclear Information System (INIS)

    1979-01-01

    The three international organizations competent in the field of irradiation processing for the preservation of food (FAO, WHO, IAEA), convened, at the end of 1977, an Advisory Group to revise and update the recommendations of a similar group which met in early 1972. The Advisory Group considered how national regulations could be harmonized so as to facilitate the international movement of irradiated food. This publication contains the Report of the Advisory Group, which summarizes the considerations of the Group on regulatory control over the irradiation plant and irradiation of foods, and on assurances for comparability of control (international labelling and documentation). Annexes 1 to 6 are included in order to complete the relevant information on the legal aspects of this subject. They include a Draft General Standard for Irradiated Foods, a Draft Code of Practice for the Operation of Radiation Facilities Used for the Treatment of Foods, Recommendations of a Consultation Group on the Legal Aspects of Food Irradiation, a Listing of the Legislation on Food Irradiation Adopted in Member States (1971-1976), and Model Regulations for the Control of and Trade in Irradiated Food

    2017-06-01

    Full Text Available The external control in Brazil is constitutional attribution of the legislative power, with the assistance of the Courts of Accounts and aims to oversee the public administration regarding legality, impersonality, morality, efficiency and others. This type of control presupposes a public management, in all areas, proba and efficient, that attends to the yearnings of the society. However, the current news about corruption investigations in the Brazilian public administration indicates that there are flaws in the external control carried out by the Audit Courts. For the relevance of the question, this article intends to investigate the causes of this inefficiency and the alternatives that present to correct it.

  16. The parameters controlling the strength of soil-steel structures

    International Nuclear Information System (INIS)

    Barkhordari, M. A.; Abdel-Sayed, G.

    2001-01-01

    The present paper examines the ultimate load carrying capacity of soil-steel structures taking into consideration the sequence of the developments of plastic hinges, their location, and their sustained plastic moment. Non-linear analysis has been conducted using a micro-computer program in which a structural model is applied with the soil replaced by normal and tangential springs acting at the nodal points of a polygon representing the conduit wall. A comparative study has been conducted for the parameters which affect the load carrying capacity of soil-steel structure, leading to the following conclusions: (1) the load carrying capacity of the composite structure is significantly affected by the shear stiffness (or friction) of the surrounding soil; (2) the conduit span may be used when calculating the buckling load rather than the local radius of the conduit wall; (3) circular arches with sector angle of less than 180 d eg have higher load carrying capacity than equivalent re-entrant arches, i.e. arches with sector angle of more than 180 d eg; (4) the buckling load of the conduit is slightly affected by the rigidity of the lower zone of the conduit wall; (5) eccentric application of the load has practically little effect on its load carrying capacity

  19. Structural properties of the material control and accounting system

    International Nuclear Information System (INIS)

    1978-12-01

    A unified digraph approach is proposed for the assessment of the structure of the MC and A System. The approach emphasizes the two structural aspects of the system: vulnerability and reliability. Vulnerability is defined as a possibility of loosing connectedness in a given structure due to line and/or node removals. It is purely deterministic notion which leads to a qualitative analysis of redundancy of connections in the corresponding system. Reliability of the MC and A System structure provides a more quantitative way of assessing how safe the system is to random failures of the links representing lines of communication, material paths, monitors, and the components of the power supply network. By assigning probabilities to the lines and nodes of the corresponding digraph, the least reliable path can be used as a measure of the goodness of the system, which can be computed by efficient shortest path algorithms. Both vulnerability and reliability considerations are important in determining the effect of tampering of an adversary with the elements of the MC and M System

    2015-01-01

    This work deals with the realization of interdigital transducers (IDT) in order to characterize the quality of coatings and surfaces of structures. The challenge of this study is three fold. Firstly, the aim is to have efficient sensors to generate surface acoustic wave (SAW) since these wave sare well suited for this type of characterization. The second objective ofthis study is to provide flexible sensors so that they can adapt to different shapes of structures. Finally, relatively inexpensive technologies are favored for the development of these sensors because this allows continuous monitoring (structural health monitoring) by incorporating these sensors permanently on the structures to be tested. To meet these goals, several French and Belgian laboratories have gathered around the PRISTIFLEX project INTERREG IV. After a presentation of the manufacturing process and the characteristics of the piezo electric material developed in this study, we discussed modeling which helped to define the dimensional parameters of the piezo electric plate that composes the sensor. Then, the techniques for producing the electrodes (laserablation and inkjet printing) were presented and an example of performed electrode was provided. Finally, the effectiveness of these sensors from the measurement of the displacement caused by the surface wave excited by these IDT sensors were demonstrated. (author)

  1. Structurally Efficient Three-dimensional Metamaterials with Controllable Thermal Expansion

    Science.gov (United States)

    Xu, Hang; Pasini, Damiano

    2016-01-01

    The coefficient of thermal expansion (CTE) of architected materials, as opposed to that of conventional solids, can be tuned to zero by intentionally altering the geometry of their structural layout. Existing material architectures, however, achieve CTE tunability only with a sacrifice in structural efficiency, i.e. a drop in both their stiffness to mass ratio and strength to mass ratio. In this work, we elucidate how to resolve the trade-off between CTE tunability and structural efficiency and present a lightweight bi-material architecture that not only is stiffer and stronger than other 3D architected materials, but also has a highly tunable CTE. Via a combination of physical experiments on 3D fabricated prototypes and numeric simulations, we demonstrate how two distinct mechanisms of thermal expansion appearing in a tetrahedron, can be exploited in an Octet lattice to generate a large range of CTE values, including negative, zero, or positive, with no loss in structural efficiency. The novelty and simplicity of the proposed design as well as the ease in fabrication, make this bi-material architecture well-suited for a wide range of applications, including satellite antennas, space optical systems, precision instruments, thermal actuators, and MEMS.

  3. Atomic Structure Control of Silica Thin Films on Pt(111)

    KAUST Repository

    Crampton, Andrew S

    2015-05-27

    Metal oxide thin films grown on metal single crystals are commonly used to model heterogeneous catalyst supports. The structure and properties of thin silicon dioxide films grown on metal single crystals have only recently been thoroughly characterized and their spectral properties well established. We report the successful growth of a three- dimensional, vitreous silicon dioxide thin film on the Pt(111) surface and reproduce the closed bilayer structure previously reported. The confirmation of the three dimensional nature of the film is unequivocally shown by the infrared absorption band at 1252 cm−1. Temperature programmed desorption was used to show that this three-dimensional thin film covers the Pt(111) surface to such an extent that its application as a catalyst support for clusters/nanoparticles is possible. The growth of a three-dimensional film was seen to be directly correlated with the amount of oxygen present on the surface after the silicon evaporation process. This excess of oxygen is tentatively attributed to atomic oxygen being generated in the evaporator. The identification of atomic oxygen as a necessary building block for the formation of a three-dimensional thin film opens up new possibilities for thin film growth on metal supports, whereby simply changing the type of oxygen enables thin films with different atomic structures to be synthesized. This is a novel approach to tune the synthesis parameters of thin films to grow a specific structure and expands the options for modeling common amorphous silica supports under ultra high vacuum conditions.

  13. [The debate over drug legalization].

    Science.gov (United States)

    Babín Vich, Francisco de Asís

    2013-01-01

    The debate over drug legalization appears frequently in the media as a potential solution to issues such as drug trafficking and other problems related to drug use. In Spain, private consumption or even the production of small quantities of certain plants, whose active ingredients are considered illegal drugs, if clearly for own consumption are not practices criminalized by any law. In addition, a drug addict is considered a person who is ill. Although it has not always been like that even in the countries that have called for this debate, where at times the law prosecutes consumers. The population of our country, according to the views expressed in the opinion polls, prefer to increase preventive measures, foster the treatment freely assumed by drug addicts and make stricter the repression on drug trafficking. Therefore, when speaking of "legalization" we should be scrupulous with the semantics; legalize and decriminalize are not the same, it is not the same decriminalize consumption than decriminalize trafficking, neither is the same decriminalize private consumption than public consumption. Decriminalize private consumption is a fact in our country. Beyond this, we advocate for the strict need to analyze from a scientific perspective the hypothetical benefits that would result from drug legalization. Certainly, from the public health perspective, they are hard to find. We believe that the same logic applied to tobacco, increasing the restrictions on its use, is the path to follow with any addictive substance.

  15. Pole placement algorithm for control of civil structures subjected to earthquake excitation

    2017-04-01

    Full Text Available In this paper the control algorithm for controlled civil structures subjected to earthquake excitation is thoroughly investigated. The objective of this work is the control of structures by means of the pole placement algorithm, in order to improve their response against earthquake actions. Successful application of the algorithm requires judicious placement of the closed-loop eigenvalues from the part of the designer. The pole placement algorithm was widely applied to control mechanical systems. In this paper, a modification in the mathematical background of the algorithm in order to be suitable for civil fixed structures is primarily presented. The proposed approach is demonstrated by numerical simulations for the control of both single and multi-degree of freedom systems subjected to seismic actions. Numerical results have shown that the control algorithm is efficient in reducing the response of building structures, with small amount of required control forces.

  16. Social Media Users’ Legal Consciousness About Privacy

    2017-02-01

    Full Text Available This article explores the ways in which the concept of privacy is understood in the context of social media and with regard to users’ awareness of privacy policies and laws in the ‘Post-Snowden’ era. In the light of presumably increased public exposure to privacy debates, generated partly due to the European “Right to be Forgotten” ruling and the Snowden revelations on mass surveillance, this article explores users’ meaning-making of privacy as a matter of legal dimension in terms of its violations and threats online and users’ ways of negotiating their Internet use, in particular social networking sites. Drawing on the concept of legal consciousness, this article explores through focus group interviews the ways in which social media users negotiate privacy violations and what role their understanding of privacy laws (or lack thereof might play in their strategies of negotiation. The findings are threefold: first, privacy is understood almost universally as a matter of controlling one’s own data, including information disclosure even to friends, and is strongly connected to issues about personal autonomy; second, a form of resignation with respect to control over personal data appears to coexist with a recognized need to protect one’s private data, while respondents describe conscious attempts to circumvent systems of monitoring or violation of privacy, and third, despite widespread coverage of privacy legal issues in the press, respondents’ concerns about and engagement in “self-protecting” tactics derive largely from being personally affected by violations of law and privacy.

  5. Aerodynamics of unmanned combat air vehicles: Flow structure and control

    Science.gov (United States)

    Elkhoury, Michel

    At moderate to high angle-of-attack, an Unmanned Combat Air Vehicle (UCAV) exhibits complex flow structure due to vortex interaction/breakdown, and the onset of separation and stall. These features of the flow patterns have received little attention. The present investigation addresses the degree of interaction of vortices, the onset of vortex breakdown, and the occurrence of a separation as a function of both Reynolds number and angle-of-attack, via dye visualization and quantitative imaging. The Reynolds number dependence of the near-surface flow structure and topology on a representative UCAV planform is characterized using a technique of high-image-density particle image velocimetry (DPIV), as a complement to classical dye visualization. This technique provides a sequence of instantaneous states, as well as the corresponding time-averaged state. Patterns of streamline topology, including bifurcation lines, contours of streamwise and transverse velocity, surface-normal vorticity and Reynolds stress correlation, all immediately adjacent to the surface of the planform, provide quantitative interpretations. At low angle-of-attack, these quantitative patterns show significant alterations with Reynolds number, as represented by: large variations of patterns of vortex breakdown and vortex interaction visualized by dye; and substantial alterations of flow patterns in the crossflow plane, including reattachment phenomena, which are interpreted with patterns of velocity and streamwise vorticity. On the other hand, at moderate angle-of-attack, the near-surface quantitative patterns show much less sensitivity to Reynolds number, which is in accord with weak variations of the onset of vortex breakdown with changes in Reynolds number. Perturbations of the planform at a small amplitude and high frequency can substantially alter both the instantaneous and time-averaged flow structure immediately adjacent to its surface, relative to the case of a stationary planform.

  9. Tuners, microphonics, and control systems in superconducting accelerating structures

    International Nuclear Information System (INIS)

    Doolittle, L.R.

    1990-01-01

    Manufacturing tolerances, thermal stresses, acoustic noise, and cooling fluid pressure fluctuations all conspire to make the field in the cavity not precisely what the accelerator physicist has in mind. Tuners and control systems are the tools used to fight back: they regulate the field in the cavity to the desired magnitude and phase. Amplitude and phase stabilities are usually of greater concern in superconducting cavities than in copper cavities. The key to achieving a stable gradient and phase is feedback. A probe must be placed in the cavity itself to sense the present cavity status. Electronic control is then given the responsibility to correct for any measured disturbance. The electronic modulation of forward power has been implemented in a number of ways. Perhaps the easiest implementation to understand has two separate control loops, one for amplitude and one for phase (phase-amplitude loops). Other major electronic control devices include complex phasor modulator (CPM-amplitude loops), vector loop, and variable reactance. 'Slow' tuners are used when the tuning range of the 'fast' tuner plus electronic tuning is not enough to compensate for unpredictability or drift in the static frequency setting. (N.K.)

    Carbon export from high elevation ecosystems is a critical component of the global carbon cycle. Ecosystems in northern latitudes have become the focus of much research due to their potential as large sinks of carbon in the atmosphere. However, there exists limited understanding of the controls of carbon export from complex mountain catchments due to strong spatial and...

  11. Control of flexible structures with distributed sensing and processing

    Technology is being developed to process signals from distributed sensors using distributed computations. These distributed sensors provide a new feedback capability for vibration control that has not been exploited. Additionally, the sensors proposed are of an optical and distributed nature and could be employed with known techniques of distributed optical computation (Fourier optics, etc.) to accomplish the control system functions of filtering and regulation in a distributed computer. This paper extends the traditional digital, optimal estimation and control theory to include distributed sensing and processing for this application. The design model assumes a finite number of modes which make it amenable to empirical determination of the design model via familiar modal-test techniques. The sensors are assumed to be distributed, but a finite number of point actuators are used. The design process is illustrated by application to a Euler beam. A simulation of the beam is used to design an optimal vibration control system that uses a distributed deflection sensor and nine linear force actuators. Simulations are also used to study the influence of design and processing errors on the performance.

    The control of flexible spacecraft is a difficult problem because of large number of elastic modes; low value, closely-spaced frequencies; very small damping; and uncertainties in math models. The traditional design approach is to design the structure first and then to design the control system. This view-graph presentation develops a methodology for spacecraft design which addresses control/structure interaction issues, produces technology for simultaneous control/structure design, and translates into algorithms and computational tools for practical integrated computer-aided design.

  14. Legal protection against nuclear damage

    International Nuclear Information System (INIS)

    1959-01-01

    The IAEA Director General appointed an international Panel of Experts to go into the question of Civil Liability and State Responsibility for Nuclear Hazards. The Panel had before it certain basic postulates formulated after a preliminary and tentative consideration of the subject. From the viewpoint of the public, the first postulate is, of course, that the use of nuclear energy be regulated by adequate licensing and control mechanisms so as to prevent any accidents. To the extent, however, that nuclear damage cannot be prevented, there must be liability on the part of the enterprise which caused the damage and, where damage exceeds its liability or its financial resources there should be some assurance of compensation by the State. This should be so not only within the borders of one State, but especially also on an international basis. Security should be required for the possible liability of the enterprises connected with a nuclear incident. Litigation with respect to liability should be concentrated in the most convenient tribunal and be governed by a single clearly defined law. The methods of distribution should meet general standards of equity and be as expeditious as possible. Emergency measures, especially evacuation, first aid and decontamination, should be organized and financed without delay. At the same time, the liability of an enterprise should not exceed its reasonable financial capabilities. This means that a ceiling should be imposed upon the amount of third party liability to which an enterprise could be held. And the liability should generally be such as can be covered by adequate financial security. Uniformity in the treatment of victims of nuclear incidents in all these fields is a desirable goal. Yet, if a rule adopted on an international level or suggested by uniform legislation were to be viable, it should adapt itself to the social, economic and legal order already existing in individual States. This may mean that in certain fields it

    The anoxic-oxic (A/O) municipal wastewater treatment plant (WWTP) of Manresa (Catalonia, Spain) was studied for a possible conversion to an anaerobic/anoxic/oxic (A2/O) configuration to promote enhanced biological phosphorus removal. The control structure had to be redesigned to satisfy the new necessity to control phosphorus concentration, besides ammonium and nitrate concentrations (main pollutant concentrations). Thereby, decentralized control structures with proportional-integral-derivative (PID) controllers and centralized control structures with model-predictive controllers (MPC) were designed and tested. All the designed control structures had their performance systematically tested regarding effluent quality and operating costs. The centralized control structure, A2/O-3-MPC, achieved the lowest operating costs with the best effluent quality using the A2/O plant configuration for the Manresa WWTP. The controlled variables used in this control structure were ammonium in the effluent, nitrate at the end of the anoxic zone and phosphate at the end of the anaerobic zone, while the manipulated variables were the internal and external recycle flow rates and the dissolved oxygen setpoint in the aerobic reactors.

    Full Text Available This paper reconstructs the development of the status of the theory of legal pluralism: while originally the term has been used as descriptive label referring to a situation observed in the world, nowadays a more sophisticated understanding of the role of the concept is needed. The epistemology of social sciences can help us make sense of the multifarious literature on legal pluralism, and of the different conceptions of the term that have been proposed. More specifically, legal pluralism is here devised as a theoretical programme and its influence on the production of social-scientific knowledge is analysed. The investigation concentrates on the role of the concept in the selection of relevant data and on the intelligibility structure imposed on them.Este artículo reconstruye el desarrollo de la situación de la teoría de pluralismo jurídico: aunque en un principio el término se utilizó como una etiqueta descriptiva referida a una situación que se observaba en el mundo, hoy en día se necesita una comprensión más sofisticada del rol del concepto. La epistemología de las ciencias sociales puede ayudar a dar sentido a la literatura heterogénea sobre pluralismo jurídico, así como a las diferentes concepciones del término que se han propuesto. Más específicamente, aquí se concibe el pluralismo jurídico como un programa teórico y se analiza su influencia en la producción de conocimiento científico social. La investigación se concentra en el papel del concepto en la selección de datos relevantes y en la estructura de inteligibilidad impuesta sobre ellos.DOWNLOAD THIS PAPER FROM SSRN: http://ssrn.com/abstract=2833822

  17. Integrating Structural Health Management with Contingency Control for Wind Turbines

    Full Text Available Maximizing turbine up-time and reducing maintenance costs are key technology drivers for wind turbine operators. Components within wind turbines are subject to considerable stresses due to unpredictable environmental conditions resulting from rapidly changing local dynamics. In that context, systems health management has the aim to assess the state-of-health of components within a wind turbine, to estimate remaining life, and to aid in autonomous decision-making to minimize damage to the turbine. Advanced contingency control is one way to enable autonomous decision-making by providing the mechanism to enable safe and efficient turbine operation. The work reported herein explores the integration of condition monitoring of wind turbine blades with contingency control to balance the trade-offs between maintaining system health and energy capture. Results are demonstrated using a high fidelity simulator of a utility-scale wind turbine.

    We prove that the integrand of magnetic skyrmions can be expressed as curvature tensor of Wu-Yang potential. Taking the projection of the normalized magnetization vector on the 2-dim material surface, and according to Duan's decomposition theory of gauge potential, we reveal that every single skyrmion is just characterized by Hopf index and Brouwer degree at the zero point of this vector field. Our theory meet the results that experimental physicists have achieved by many technologies. The inner topological structure expression of skyrmion with Hopf index and Brouwer degree will be indispensable mathematical basis of skyrmion logic gates.
