Performance Comparison of the Optimized Inverted Joined Wing Airplane Concept and Classical Configuration Airplanes

Directory of Open Access Journals (Sweden)

Sieradzki Adam

2016-09-01

Full Text Available The joined wing concept is an unconventional airplane configuration, known since the mid-twenties of the last century. It has several possible advantages, like reduction of the induced drag and weight due to the closed wing concept. The inverted joined wing variant is its rarely considered version, with the front wing being situated above the aft wing. The following paper presents a performance prediction of the recently optimized configuration of this airplane. Flight characteristics obtained numerically were compared with the performance of two classical configuration airplanes of similar category. Their computational fluid dynamics (CFD models were created basing on available documentation, photographs and some inverse engineering methods. The analysis included simulations performed for a scale of 3-meter wingspan inverted joined wing demonstrator and also for real-scale manned airplanes. Therefore, the results of CFD calculations allowed us to assess the competitiveness of the presented concept, as compared to the most technologically advanced airplanes designed and manufactured to date. At the end of the paper, the areas where the inverted joined wing is better than conventional airplane were predicted and new research possibilities were described.

Public Relations between Occupation and Profession – Attempts at Regulating Public Relations

Directory of Open Access Journals (Sweden)

Božo Skoko

2012-06-01

Full Text Available This paper is concerned with the regulation and the professionalization of occupations in public relations. It analyzes the role of professional, national associations in the professionalization process, providing an overview of these organizations in various countries around the world. The authors identify countries with no regulation (for instance, Italy, countries with some legal regulations (for instance, Brazil and countries that have adopted self-regulation models (for instance, USA and South Africa. The authors point out the advantages and drawbacks of each regulation model and their impact on the development and professionalization of the occupation. Namely, in countries in which public relations are defined by law, public relations experts have guaranteed positions in society; however, they enjoy a negative public perception. In self-regulatory models, a significant number of experts are not covered by membership in organizations. Consequently, their behavior is not governed by any set of established professional obligations. Furthermore, countries with no clear professional regulation have enabled mass engagement in public relations; however, there are no criteria for professional advancement and affirmation. The issue of regulation in transition countries has shown itself to be a relatively unarticulated concept that can be expected to acquire greater definition with further professionalization of the occupation, a key role that must be played by professional associations.

Science.gov (United States)

Dana, William H.

1993-01-01

The X-15 rocket research airplane flew to an altitude of 354,000 ft and reached Mach 6.70. In almost 200 flights, this airplane was used to gather aerodynamic-heating, structural loads, stability and control, and atmospheric-reentry data. This paper describes the origins, design, and operation of the X-15 airplane. In addition, lessons learned from the X-15 airplane that are applicable to designing and testing the National Aero-Space Plane are discussed.

Recurring norovirus transmission on an airplane.

Science.gov (United States)

Thornley, Craig N; Emslie, Nicola A; Sprott, Tim W; Greening, Gail E; Rapana, Jackie P

2011-09-01

Previously reported outbreaks of norovirus gastroenteritis associated with aircraft have been limited to transmission during a single flight sector. During October 2009, an outbreak of diarrhea and vomiting occurred among different groups of flight attendants who had worked on separate flight sectors on the same airplane. We investigated the cause of the outbreak and whether the illnesses were attributable to work on the airplane. Information was obtained from flight attendants on demographic characteristics, symptoms, and possible transmission risk factors. Case patients were defined as flight attendants with diarrhea or vomiting airplane during 13-18 October 2009. Stool samples were tested for norovirus RNA. A passenger had vomited on the Boeing 777-200 airplane on the 13 October flight sector. Sixty-three (82%) of 77 flight attendants who worked on the airplane during 13-18 October provided information, and 27 (43%) met the case definition. The attack rate among flight attendants decreased significantly over successive flight sectors from 13 October onward (P airplane during successive flight sectors. Airlines should make provision for adequate disinfection of airplanes with use of products effective against norovirus and other common infectious agents after vomiting has occurred.

Air resistance measurements on actual airplane parts

Science.gov (United States)

Weiselsberger, C

1923-01-01

For the calculation of the parasite resistance of an airplane, a knowledge of the resistance of the individual structural and accessory parts is necessary. The most reliable basis for this is given by tests with actual airplane parts at airspeeds which occur in practice. The data given here relate to the landing gear of a Siemanms-Schuckert DI airplane; the landing gear of a 'Luftfahrzeug-Gesellschaft' airplane (type Roland Dlla); landing gear of a 'Flugzeugbau Friedrichshafen' G airplane; a machine gun, and the exhaust manifold of a 269 HP engine.

Airplane Upset Training Evaluation Report

Science.gov (United States)

Gawron, Valerie J.; Jones, Patricia M. (Technical Monitor)

2002-01-01

Airplane upset accidents are a leading factor in hull losses and fatalities. This study compared five types of airplane-upset training. Each group was composed of eight, non-military pilots flying in their probationary year for airlines operating in the United States. The first group, 'No aero / no upset,' was made up of pilots without any airplane upset training or aerobatic flight experience; the second group, 'Aero/no upset,' of pilots without any airplane-upset training but with aerobatic experience; the third group, 'No aero/upset,' of pilots who had received airplane-upset training in both ground school and in the simulator; the fourth group, 'Aero/upset,' received the same training as Group Three but in addition had aerobatic flight experience; and the fifth group, 'In-flight' received in-flight airplane upset training using an instrumented in-flight simulator. Recovery performance indicated that clearly training works - specifically, all 40 pilots recovered from the windshear upset. However few pilots were trained or understood the use of bank to change the direction of the lift vector to recover from nose high upsets. Further, very few thought of, or used differential thrust to recover from rudder or aileron induced roll upsets. In addition, recovery from icing-induced stalls was inadequate.

Flatulence on airplanes

DEFF Research Database (Denmark)

Pommergaard, Hans C; Burcharth, Jakob; Fischer, Anders

2013-01-01

Flatus is natural and an invariable consequence of digestion, however at times it creates problems of social character due to sound and odour. This problem may be more significant on commercial airplanes where many people are seated in limited space and where changes in volume of intestinal gases......, due to altered cabin pressure, increase the amount of potential flatus. Holding back flatus on an airplane may cause significant discomfort and physical symptoms, whereas releasing flatus potentially presents social complications. To avoid this problem we humbly propose that active charcoal should...... airplanes, by using a methane breath test or to alter the fibre content of airline meals in order to reduce its flatulent potential. We conclude that the use of active charcoal on airlines may improve flight comfort for all passengers....

ON MODERN APPROACH TO AIRPLANE-TYPE UNMANNED AERIAL VEHICLES DESIGN WITH SHORT TAKEOFF AND LANDING

Directory of Open Access Journals (Sweden)

Oleg P. Minin

2017-11-01

Full Text Available This publication opens a series of review papers devoted to the current design problems of the next generation unmanned airplanes that are expected to appear in the period from 2025 to 2035. The series of papers considers airplanes with vertical take-off and landing, air launch of small satellites into the orbit, cargo transportation tasks, issues related to new aerodynamic forms, as well as hybrid, combined and distributed power units. The first paper of the cycle is devoted to the conceptual aerodynamic design of the airplanes with a short take-off and landing, and with technical and economic characteristics on cruise flight conditions no worse than for traditional airplane based on aerodrome with long airstrip. We consider traditional linear methods for aerodynamic scheme analysis and weight analysis, as well. The main relationships and references to the works enabling the parametric analysis of the aerodynamic configuration are given. It is concluded that one of the most promising areas in the field of airplanes with a short take-off and landing is the development of aerodynamic circuits constructed as a "flying wing" of small aspect ratio and large structural height.

Optimal back-to-front airplane boarding

Science.gov (United States)

Bachmat, Eitan; Khachaturov, Vassilii; Kuperman, Ran

2013-06-01

The problem of finding an optimal back-to-front airplane boarding policy is explored, using a mathematical model that is related to the 1+1 polynuclear growth model with concave boundary conditions and to causal sets in gravity. We study all airplane configurations and boarding group sizes. Optimal boarding policies for various airplane configurations are presented. Detailed calculations are provided along with simulations that support the main conclusions of the theory. We show that the effectiveness of back-to-front policies undergoes a phase transition when passing from lightly congested airplanes to heavily congested airplanes. The phase transition also affects the nature of the optimal or near-optimal policies. Under what we consider to be realistic conditions, optimal back-to-front policies lead to a modest 8-12% improvement in boarding time over random (no policy) boarding, using two boarding groups. Having more than two groups is not effective.

Simulation of Dynamics of a Flexible Miniature Airplane

Science.gov (United States)

Waszak, Martin R.

2005-01-01

A short report discusses selected aspects of the development of the University of Florida micro-aerial vehicle (UFMAV) basically, a miniature airplane that has a flexible wing and is representative of a new class of airplanes that would operate autonomously or under remote control and be used for surveillance and/or scientific observation. The flexibility of the wing is to be optimized such that passive deformation of the wing in the presence of aerodynamic disturbances would reduce the overall response of the airplane to disturbances, thereby rendering the airplane more stable as an observation platform. The aspect of the development emphasized in the report is that of computational simulation of dynamics of the UFMAV in flight, for the purpose of generating mathematical models for use in designing control systems for the airplane. The simulations are performed by use of data from a wind-tunnel test of the airplane in combination with commercial software, in which are codified a standard set of equations of motion of an airplane, and a set of mathematical routines to compute trim conditions and extract linear state space models.

Better Regulation and Public Procurement in Slovenian Municipalities

Directory of Open Access Journals (Sweden)

Maja KLUN

2013-02-01

Full Text Available The reduction of administrative burdens is a measure to improve regulatory quality. Most measures are directed towards reducing barriers for business while the issue of regulation inside government is not often posed. The research carried out in 2010 was intended to investigate how Slovenian municipalities and others in the public sector perceive measures to reduce administrative burdens and the areas in which they consider regulations to present the greatest burden. Results have shown that public procurement regulations are the greatest burden for municipalities and the public sector as a whole. Further research indicates which public procurement procedures municipalities used most often and what benefits they perceive in the amended legislation. Results indicate that most municipalities use open procedures most often, which procedurally is the most complex.

Professional Self-Regulation and the Public Interest in Canada

Directory of Open Access Journals (Sweden)

Tracey L. Adams

2016-09-01

Full Text Available The regulation of professional groups has often been justified as being in the public interest. In recent decades, policymakers in Anglo-American countries have questioned whether self-regulating professions have truly served the public interest, or whether they have merely acted in their own interests. This paper draws on legislative records and policy reports to explore meanings attached to professional self-regulation and the public interest in Canada by state actors over the past 150 years. The findings point to a shift in the definition of the public interest away from service quality and professional interests, towards efficiency, human rights, consumer choice, and in some contexts business interests. Changing views of the public interest contribute to regulatory change.

Federal Aviation Regulations - National Aviation Regulations of Russia

Science.gov (United States)

Chernykh, O.; Bakiiev, M.

2018-03-01

Chinese Aerospace Engineering is currently developing cooperation with Russia on a wide-body airplane project that has directed the work towards better understanding of Russian airworthiness management system. The paper introduces national Aviation regulations of Russia, presents a comparison of them with worldwide recognized regulations, and highlights typical differences. They have been found to be: two general types of regulations used in Russia (Aviation Regulations and Federal Aviation Regulations), non-unified structure of regulations on Aircraft Operation management, various separate agencies responsible for regulation issuance instead of one national aviation authority, typical confusions in references. The paper also gives a list of effective Russian Regulations of both types.

Building, measuring and improving public confidence in the nuclear regulator

International Nuclear Information System (INIS)

2006-01-01

An important factor for public confidence in the nuclear regulator is the general public trust of the government and its representatives, which is clearly not the same in all countries. Likewise, cultural differences between countries can be considerable, and similar means of communication between government authorities and the public may not be universally effective. Nevertheless, this workshop identified a number of common principles for the communication of nuclear regulatory decisions that can be recommended to all regulators. They have been cited in particular for their ability to help build, measure and/or improve overall public confidence in the nuclear regulator. (author)

Strategy for public understanding and participation in nuclear safety regulation

Energy Technology Data Exchange (ETDEWEB)

Kim, H. J.; Chung, Yun Hyung

2004-02-15

The objective of this study is to help the general public and local residents to better understand and trust nuclear safety regulation. In order to obtain public confidence in nuclear safety regulation, the emotion and demand of public should be first understood and the change in an attitude to meet the present circumstances actively is requisite. Hence it is intended that a genuine communication shall be newly arranged and accomplished on the basis of mutual understanding. To achieve this, a series of public opinion poll have performed periodically and symposium for the public acceptance is held in order to frame a policy based on the understanding of nuclear safety and regulation of the general public and local residents. Besides nuclear safety indicators including safety sentiment indicators are being developed as a means to understand the safety of operating nuclear power plants from the viewpoint of the general public, a plan for the harmonious communication of nuclear safety information is established, and handbooks of nuclear terminologies and report-writing are under development in part. Finally plans for convergence of the public opinions and a wide public involvement in nuclear safety regulation are formulated and their applicability as organization and administration program is now under consideration.

Simple Electromagnetic Modeling of Small Airplanes: Neural Network Approach

Directory of Open Access Journals (Sweden)

P. Tobola

2009-04-01

Full Text Available The paper deals with the development of simple electromagnetic models of small airplanes, which can contain composite materials in their construction. Electromagnetic waves can penetrate through the surface of the aircraft due to the specific electromagnetic properties of the composite materials, which can increase the intensity of fields inside the airplane and can negatively influence the functionality of the sensitive avionics. The airplane is simulated by two parallel dielectric layers (the left-hand side wall and the right-hand side wall of the airplane. The layers are put into a rectangular metallic waveguide terminated by the absorber in order to simulate the illumination of the airplane by the external wave (both of the harmonic nature and pulse one. Thanks to the simplicity of the model, the parametric analysis can be performed, and the results can be used in order to train an artificial neural network. The trained networks excel in further reduction of CPU-time demands of an airplane modeling.

Kararizou, Evangelia; Anagnostou, Evangelos; Paraskevas, George P; Vassilopoulou, Sofia D; Naoumis, Dimitrios; Kararizos, Grigoris; Spengos, Konstantinos

2011-08-01

Headache related to airplane flights is rare. We describe a 37-year-old female patient with multiple intense, jabbing headache episodes over the last 3 years that occur exclusively during airplane flights. The pain manifests during take-off and landing, and is located always in the left retro-orbital and frontotemporal area. It is occasionally accompanied by dizziness, but no additional symptoms occur. Pain intensity diminishes and disappears after 15-20 min. Apart from occasional dizziness, no other symptoms occur. The patient has a history of tension-type headache and polycystic ovaries. Blood tests and imaging revealed no abnormalities. Here, we present the first case in Greece. We review the current literature on this rare syndrome and discuss on possible pathophysiology and the investigation of possible co-factors such as anxiety and depression.

Do the public think medical regulation keep them safe?

Science.gov (United States)

Yam, Carrie Ho-Kwan; Wong, Eliza Lai-Yi; Griffiths, Sian M; Yeoh, Eng-Kiong

2018-03-01

To assess public knowledge and expectations of the ways to assess doctors' competence to ensure patient safety. Telephone survey of a random sample of 1000 non-institutionalized Hong Kong residents. Only 5% of public were correct that doctors are not required to periodically be assessed, and 9% were correct that the doctors are not required to update knowledge and skills for renewing their license. These results echo international studies showing a low public knowledge of medical regulation. The public overwhelmingly felt a periodic assessment (92%) and requirements for continuous medical education (91%) were important processes for assuring doctors' competence. A high proportion of the public felt that lay representation in the Medical Council was insufficient. There is a significant gap between public expectations and understanding of the existing medical regulation and the actual policies and practices. Despite a lack of public knowledge, the public thought it important to have an ongoing structured monitoring and assessment mechanism to assure doctors' competence. The public also expects a greater involvement in the regulatory processes as members of the Medical Council. There is a need to review and enhance the current regulatory system to meet public expectation and ensure accountability for the privilege and trust granted by the State in professional self-regulation. In the context of our complex health system, a thorough understanding on the dynamic interactions between different institutions and their complementary roles in a meta-regulatory framework is required in assuring patient safety.

The experience on public consultation in the elaboration of nuclear regulations

International Nuclear Information System (INIS)

Monteiro, Iara A.; Pitta, Maria Adelia R.; Pereira, Enneite S.; Wieland, Patricia

2009-01-01

This paper presents and discusses the process of public consultation followed by the regulatory body, Nuclear Energy National Commission (CNEN), during the elaboration of nuclear regulations. In this paper, the due legislation on federal administration, law n. 9784/99, is referred to and the procedures established by CNEN for the elaboration of a nuclear regulation are described. The public consultation has the objective of improving the democratization of nuclear regulations elaboration process, allowing the participation of interested parties such as professional associations directly involved, organizations interested in its application and the general public. During the process of elaboration of a nuclear regulation, the basic text is, first of all, discussed and improved by a task group. This group is composed by CNEN's officials and representatives of organizations, enterprises and public agencies involved in the related area. Once the first version of the proposed regulation is ready, it is formally open to consultation and posted at CNEN website for a period of time. The suggestions, therein presented on-line, are analyzed by the task group and the conclusions are also posted at the site; those considered pertinent are incorporated to proposed regulation. As an example, the public consultation results obtained in 2008 with the revision of the CNEN-NN-6.02: Licensing of Radioactive Facilities regulation, are presented. Such results cover two aspects: the analysis of the participants profile and the analysis of the contributions. Public participation in the elaboration of nuclear regulations is a new way for CNEN to know the licensees and public demands, doubts and needs. This tool has demonstrated usefulness and therefore must be maintained by the regulatory body. (author)

Fuzzy Logic Decoupled Lateral Control for General Aviation Airplanes

Science.gov (United States)

Duerksen, Noel

1997-01-01

It has been hypothesized that a human pilot uses the same set of generic skills to control a wide variety of aircraft. If this is true, then it should be possible to construct an electronic controller which embodies this generic skill set such that it can successfully control different airplanes without being matched to a specific airplane. In an attempt to create such a system, a fuzzy logic controller was devised to control aileron or roll spoiler position. This controller was used to control bank angle for both a piston powered single engine aileron equipped airplane simulation and a business jet simulation which used spoilers for primary roll control. Overspeed, stall and overbank protection were incorporated in the form of expert systems supervisors and weighted fuzzy rules. It was found that by using the artificial intelligence techniques of fuzzy logic and expert systems, a generic lateral controller could be successfully used on two general aviation aircraft types that have very different characteristics. These controllers worked for both airplanes over their entire flight envelopes. The controllers for both airplanes were identical except for airplane specific limits (maximum allowable airspeed, throttle ]ever travel, etc.). This research validated the fact that the same fuzzy logic based controller can control two very different general aviation airplanes. It also developed the basic controller architecture and specific control parameters required for such a general controller.

Measured Engine Installation Effects of Four Civil Transport Airplanes

Science.gov (United States)

Senzig, David A.; Fleming, Gregg G.; Shepherd, Kevin P.

2001-01-01

The Federal Aviation Administration's Integrated Noise Model (INM) is one of the primary tools for land use planning around airports. The INM currently calculates airplane noise lateral attenuation using the methods contained in the Society of Automotive Engineer's Aerospace Information Report No. 1751 (SAE AIR 1751). Researchers have noted that improved lateral attenuation algorithms may improve airplane noise prediction. The authors of SAE AIR 1751 based existing methods on empirical data collected from flight tests using 1960s-technology airplanes with tail-mounted engines. To determine whether the SAE AIR 1751 methods are applicable for predicting the engine installation component of lateral attenuation for airplanes with wing-mounted engines, the National Aeronautics and Space Administration (NASA) sponsored a series of flight tests during September 2000 at their Wallops Flight Facility. Four airplanes, a Boeing 767-400, a Douglas DC-9, a Dassault Falcon 2000, and a Beech KingAir, were flown through a 20 microphone array. The airplanes were flown through the array at various power settings, flap settings, and altitudes to simulate take-off and arrival configurations. This paper presents the preliminary findings of this study.

Building concepts against airplane crash

International Nuclear Information System (INIS)

Henkel, F.O.; Woelfel, H.

1984-01-01

In Germany safety related buildings of nuclear facilities as well as their equipment are to be designed against airplane crash. While the safety of the structure itself can always be guaranteed by structural means, the induced vibrations may cause severe problems for the equipment. Considerable effort was expended in recent years to comprehend the load case airplane crash in a more exact manner and to evaluate reasonable floor response spectra. Besides this analytical effort, investigations are cited to minimize the induced vibrations by new structural concepts. The present paper gives a survey concerning the development of structural concepts, culminating in the double shell structures that are state of the art today. Then the idea of spring supports, as it is known for the aseismic foundation of buildings, is further developed to a new spring concept which reduces the induced vibrations in an optimum way in the load case airplane crash and which additionally isolates earthquake vibrations.

Amphibious Airplane

Science.gov (United States)

1986-01-01

The airplane pictured is the new Air Shark I, a four-place amphibian that makes extensive use of composite materials and cruises at close to 200 miles per hour under power from a 200-horsepower engine. Air Shark I is a "homebuilt" airplane, assembled from a kit of parts and components furnished by Freedom Master Corporation, Satellite Beach, Florida. The airplane incorporates considerable NASA technology and its construction benefited from research assistance provided by Kennedy Space Center (KSC) In designing the Shark, company president Arthur M. Lueck was able to draw on NASA's aeronautical technology bank through KSC's computerized "recon" library. As a result of his work at KSC, the wing of the Air Shark I is a new airfoil developed by Langley Research Center for light aircraft. In addition, Lueck opted for NASA-developed "winglets," vertical extensions of the wing that reduce drag by smoothing air turbulence at the wingtips. The NASA technology bank also contributed to the hull design. Lueck is considering application of NASA laminar flow technology-means of smoothing the airflow over wing and fuselage-to later models for further improvement of the Shark's aerodynamic efficiency. A materials engineer, Lueck employed his own expertise in designing and selecting the materials for the composite segments, which include all structural members, exposed surfaces and many control components. The materials are fiber reinforced plastics, or FRP They offer a high strength-to-weight ratio, with a nominal strength rating about one and a half times that of structural steel. They provide other advantages: the materials can be easily molded into finished shapes without expensive tooling or machining, and they are highly corrosion resistant. The first homebuilt to be offered by Freedom Master, Air Shark I completed air and water testing in mid-1985 and the company launched production of kits.

Public involvement in multi-objective water level regulation development projects-evaluating the applicability of public involvement methods

International Nuclear Information System (INIS)

Vaentaenen, Ari; Marttunen, Mika

2005-01-01

Public involvement is a process that involves the public in the decision making of an organization, for example a municipality or a corporation. It has developed into a widely accepted and recommended policy in environment altering projects. The EU Water Framework Directive (WFD) took force in 2000 and stresses the importance of public involvement in composing river basin management plans. Therefore, the need to develop public involvement methods for different situations and circumstances is evident. This paper describes how various public involvement methods have been applied in a development project involving the most heavily regulated lake in Finland. The objective of the project was to assess the positive and negative impacts of regulation and to find possibilities for alleviating the adverse impacts on recreational use and the aquatic ecosystem. An exceptional effort was made towards public involvement, which was closely connected to planning and decision making. The applied methods were (1) steering group work, (2) survey, (3) dialogue, (4) theme interviews, (5) public meeting and (6) workshops. The information gathered using these methods was utilized in different stages of the project, e.g., in identifying the regulation impacts, comparing alternatives and compiling the recommendations for regulation development. After describing our case and the results from the applied public involvement methods, we will discuss our experiences and the feedback from the public. We will also critically evaluate our own success in coping with public involvement challenges. In addition to that, we present general recommendations for dealing with these problematic issues based on our experiences, which provide new insights for applying various public involvement methods in multi-objective decision making projects

2015-05-01

Headache attributed to airplane flights is a rare form of headache disorder. This case study describes an 11-year-old girl with recurrent, severe, frontal headaches occurring during airplane travel. The episodes were associated with dizziness and facial pallor but no additional symptoms and showed spontaneous resolution on landing. Blood tests and imaging revealed no abnormalities. The present case fulfils the criteria for airplane headache recently included in the revised edition of the International Classification of Headache Disorders (ICHD-III Beta). Only a few cases of airplane headache have been reported in children. To our knowledge, this is the fourth case. We review the current literature on this rare syndrome and discuss various proposed pathophysiological mechanisms. © The Author(s) 2014.

Lateral-directional aerodynamic characteristics of light, twin-engine, propeller driven airplanes

1972-01-01

Analytical procedures and design data for predicting the lateral-directional static and dynamic stability and control characteristics of light, twin engine, propeller driven airplanes for propeller-off and power-on conditions are reported. Although the consideration of power effects is limited to twin engine airplanes, the propeller-off considerations are applicable to single engine airplanes as well. The procedures are applied to a twin engine, propeller driven, semi-low-wing airplane in the clean configuration through the linear lift range. The calculated derivative characteristics are compared with wind tunnel and flight data. Included in the calculated characteristics are the spiral mode, roll mode, and Dutch roll mode over the speed range of the airplane.

In order for the airplane to arrive safely in the Martian atmosphere, a number of sequences must occur. A critical element in the entry sequence at Mars is an extraction maneuver to separate the airplane quickly (in less than a second) from its protective backshell to reduce the possibility of re-contact, potentially leading to mission failure. This paper describes the development, testing, and lessons learned from building a 1/3 scale model of this airplane extraction system. This design, based on the successful Mars Exploration Rover (MER) extraction mechanism, employs a series of trucks rolling along tracks located on the surface of the central parachute can. Numerous tests using high speed video were conducted at the Langley Research Center to validate this concept. One area of concern was that that although the airplane released cleanly, a pitching moment could be introduced. While targeted for a Mars mission, this concept will enable environmental surveys by aircraft in other planetary bodies with a sensible atmosphere such as Venus or Saturn's moon, Titan.

Public regulation of nuclear plants

International Nuclear Information System (INIS)

Burtheret, M.; Cormis, de

1980-01-01

The construction and operation of nuclear plants are subject to a complex system of governmental administration. The authors list the various governmental authorisations and rules applicable to these plants. In the first part, they describe the national regulations which relate specifically to nuclear plants, and emphasize the provisions which are intended to ensure the safety of the installations and the protection of the public against ionizing radiation. However, while the safety of nuclear plants is a major concern of the authorities, other interests are also protected. This is accomplished by various laws or regulations which apply to nuclear plants as well as other industrial installations. The duties which these texts, and the administrative practice based thereon, impose on Electricite de France are covered in the second part [fr

Portable oxygen concentrators (POC) are highly desirable for patients with lung disease traveling by airplane, as these devices allow theoretically much higher travel times if additional batteries can be used. However, it is unclear whether POCs produce enough oxygen in airplanes at cruising altitude, even if complying with aviation regulations. We evaluated five frequently used POCs (XPO2 (Invacare, USA), Freestyle (AirSep C., USA), Evergo (Philipps Healthcare, Germany), Inogen One (Inogen, USA), Eclipse 3 (Sequal, USA)) at an altitude of 2650 m (as simulated airplane environment) in 11 patients with chronic obstructive lung disease (COPD) and compared theses POCs with the standard oxygen system (WS120, EMS Ltd., Germany) used by Lufthansa. Oxygen was delivered by each POC for 30 min to each patient at rest, blood gases were then drawn from the arterialized ear lobe. All POCs were able to deliver enough oxygen to increase the PaO(2) of our subjects by at least 1.40 kPa (10 mmHg). However, to achieve this increase, the two most lightweight POCs (Freestyle and Invacare XPO2) had to be run at their maximum level. This causes a significant reduction of battery life. The three other POCs (EverGo, Inogen One, Eclipse 3) and the WS120 were able to increase the PaO(2) by more than 2.55 kPa (20 mmHg), which provides extra safety for patients with more severe basal hypoxemia. When choosing the right oxygen system for air travel in patients in COPD, not only weight, but also battery life and maximum possible oxygen output must be considered carefully.

Airplane energy use and conservation strategies

Energy Technology Data Exchange (ETDEWEB)

Pilati, D.A.

1974-05-01

Domestic commercial airplane fuel use is examined as a function of stage length. A fuel use model is developed using the eight most popular airplanes. Short flights are very fuel inefficient; a 100-mile flight consumes 2.5 times as much fuel per passenger-mile than a 1,000-mile flight. Half of today's flights are for distances under 260 miles. Fuel consumption for purposes other than flying directly between airports is examined. Over 10% of total fuel use is for those portions of the flight in which no enroute distance is achieved. Delays account for at least 4.2% of the fuel consumption and auxiliary power units use over 1%. Fuel requirements for attempting to recover lost time and for fuel ferrying are also discussed. Airplane fuel efficiency can be increased in the short term by operational changes, particularly by increasing the load factor. A load factor increase from 50 to 60% would reduce airplane fuel use by 16% for the same traffic. Other options include reducing cruise speeds, increasing cruise altitudes, and changing ground operations. Each of these strategies offer savings of 1 to 3%. Total transportation energy use can be reduced by shifting air passengers to ground modes, especially for the inefficient short-stage traffic. Net energy savings for diverting half the flights under 200 miles to buses or trains is equivalent to 6% of the fleet fuel use. (6 tables, 6 fig., 36 references)

Towards trust in regulation. Moving to a public value regulation

Energy Technology Data Exchange (ETDEWEB)

2010-06-15

The UK Government has committed itself to reducing its carbon dioxide emissions. The challenge of successfully achieving a transition to a sustainable energy system, in the context of the UK's largely privately owned energy industry, rests on the ability of policy makers to encourage and enable the necessary changes or innovation at all levels of the energy system. This paper argues that the UK's current, dominant political paradigm or framework (the regulatory state paradigm (RSP)) and within it, the role of the economic regulator, Ofgem acts as a fundamental block to this challenge. The current economic regulatory system is based on trust in the market, or on predicted (albeit theoretical) known outcomes. To expand our regulatory system to one which can deliver a sustainable energy system requires innovation in a certain direction (as opposed to any innovation). That is the antithesis of the current process of regulation. Trust is required that Ofgem, the economic regulator, will develop rules and incentives which deliver an agreed sustainable energy goal, which is 'trusted' to be the 'right' goal. This requires Ofgem moving away from ex-ante regulation to a type of regulation where all costs, benefits and outcomes cannot be known beforehand and where they cannot necessarily be quantifiable. This has, very provisionally, been called Public Value Regulation (PVR). (author)

Advances in Thrust-Based Emergency Control of an Airplane

Science.gov (United States)

Creech, Gray; Burken, John J.; Burcham, Bill

2003-01-01

Engineers at NASA's Dryden Flight Research Center have received a patent on an emergency flight-control method implemented by a propulsion-controlled aircraft (PCA) system. Utilizing the preexisting auto-throttle and engine-pressure-ratio trim controls of the airplane, the PCA system provides pitch and roll control for landing an airplane safely without using aerodynamic control surfaces that have ceased to function because of a primary-flight-control-system failure. The installation of the PCA does not entail any changes in pre-existing engine hardware or software. [Aspects of the method and system at previous stages of development were reported in Thrust-Control System for Emergency Control of an Airplane (DRC-96-07), NASA Tech Briefs, Vol. 25, No. 3 (March 2001), page 68 and Emergency Landing Using Thrust Control and Shift of Weight (DRC-96-55), NASA Tech Briefs, Vol. 26, No. 5 (May 2002), page 58.]. Aircraft flight-control systems are designed with extensive redundancy to ensure low probabilities of failure. During recent years, however, several airplanes have exhibited major flight-control-system failures, leaving engine thrust as the last mode of flight control. In some of these emergency situations, engine thrusts were successfully modulated by the pilots to maintain flight paths or pitch angles, but in other situations, lateral control was also needed. In the majority of such control-system failures, crashes resulted and over 1,200 people died. The challenge lay in creating a means of sufficient degree of thrust-modulation control to safely fly and land a stricken airplane. A thrust-modulation control system designed for this purpose was flight-tested in a PCA an MD-11 airplane. The results of the flight test showed that without any operational control surfaces, a pilot can land a crippled airplane (U.S. Patent 5,330,131). The installation of the original PCA system entailed modifications not only of the flight-control computer (FCC) of the airplane but

Experimental determination of airplane mass and inertial characteristics

Science.gov (United States)

Wolowicz, C. H.; Yancey, R. B.

1974-01-01

Current practices are evaluated for experimentally determining airplane center of gravity, moments of inertia, and products of inertia. The techniques discussed are applicable to bodies other than airplanes. In pitching- and rolling-moment-of-inertia investigations with the airplane mounted on and pivoted about knife edges, the nonlinear spring moments that occur at large amplitudes of oscillation can be eliminated by using the proper spring configuration. The single-point suspension double-pendulum technique for obtaining yawing moments of inertia, products of inertia, and the inclination of the principal axis provides accurate results from yaw-mode oscillation data, provided that the sway-mode effects are minimized by proper suspension rig design. Rocking-mode effects in the data can be isolated.

Reversible cerebral vasoconstriction syndrome precipitated by airplane descent: Case report.

Science.gov (United States)

Hiraga, Akiyuki; Aotsuka, Yuya; Koide, Kyosuke; Kuwabara, Satoshi

2017-10-01

Background Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by segmental vasospasm. Vasoactive agents and childbirth have been reported as precipitating factors for RCVS; however, RCVS induced by altitude change or air travel has rarely been reported. Case We present a case of a 74-year-old woman who presented with thunderclap headache during airplane descent. Magnetic resonance angiography demonstrated segmental vasoconstriction that improved 9 days after onset. Conclusion These findings indicate that airplane descent may be a trigger of RCVS. The time course of headache in the present case was similar to that of prolonged headache attributed to airplane travel, indicating that RCVS during air travel may have previously been overlooked and that some headache attributed to airplane travel cases may represent a milder form of RCVS.

Airplane detection in remote sensing images using convolutional neural networks

Science.gov (United States)

Ouyang, Chao; Chen, Zhong; Zhang, Feng; Zhang, Yifei

2018-03-01

Airplane detection in remote sensing images remains a challenging problem and has also been taking a great interest to researchers. In this paper we propose an effective method to detect airplanes in remote sensing images using convolutional neural networks. Deep learning methods show greater advantages than the traditional methods with the rise of deep neural networks in target detection, and we give an explanation why this happens. To improve the performance on detection of airplane, we combine a region proposal algorithm with convolutional neural networks. And in the training phase, we divide the background into multi classes rather than one class, which can reduce false alarms. Our experimental results show that the proposed method is effective and robust in detecting airplane.

Atmospheric electron flux at airplane altitude

We have developed a new detector to systematically measure the cosmic-ray electron flux at airplane altitudes. We loaded a lead-glass-based electron telescope onto a commercial cargo airplane. The first experiment was carried out using the air route between Narita (Japan) and Sydney (Australia); during this flight we measured the electron flux at various altitudes and latitudes. The thresholds of the electron energies were 1, 2, and 4 GeV. The results agree with a simple estimation using one-dimensional shower theory. A comparison with a Monte Carlo calculation was made

For the 2014 World Cup and the 2016 Olympic Games, Brazil has expanded its airport infrastructure. This will lead to an increase in wastewater generation from aircrafts. This wastewater is traditionally taken from the aircrafts and disposed in the public sewage collection system. However, this residual water may have a different composition than the usual sanitary sewage. Therefore, it is important to study an alternative to treat this kind of wastewater. Thus, the objective of this study was to characterize and analyze the treatment of wastewater from airplane toilets through chemical precipitation for the removal of ammonia in the form of struvite. The airplanes' effluent showed a composition similar to human urine with pH 8.9, ammonia nitrogen 4,215 mg L -1 , phosphorus 430 mg L -1 and a very high acute toxicity (Vibrio fischeri). The best treatment for struvite formation was with pH 9.0 and molar ratio Mg:NH 4 :PO 4 equal to 1.5:1.0:1.0. In this case, the removal of ammonia and phosphorus achieved 97.0% and 95.3%, respectively. After this procedure, the toxicity by Vibrio fischeri decreased.

While injuries to the spine after an airplane crash are not rare, most crashes result in fatal injuries. As such, few studies exist that reported on spine fractures sustained during airplane accidents. In this report, we demonstrate three cases of spine fractures due to crash landing of a commercial airplane. Three passengers perished from injuries after the crash landing, yet most of the passengers and crew on board survived, with injuries ranging from minor to severe. Through evaluating our three spine fracture patients, it was determined that compression fracture of the spine was the primary injury related to the airplane accident. The first patient was a 20-year-old female who sustained a T6-8 compression fracture without neurologic deterioration. The second patient was a 33-year-old female with an L2 compression fracture, and the last patient was a 49-year-old male patient with a T8 compression fracture. All three patients were managed conservatively and required spinal orthotics. During the crash, each of these patients were subjected to direct, downward high gravity z-axis (Gz) force, which gave rise to load on the spine vertically, thereby causing compression fracture. Therefore, new safety methods should be developed to prevent excessive Gz force during airplane crash landings.

To evaluate the effect of long haul airplane transport of donor livers on post-transplant outcomes. A retrospective cohort study of patients who received a liver transplantation was performed in Perth, Australia from 1992 to 2012. Donor and recipient characteristics information were extracted from Western Australian liver transplantation service database. Patients were followed up for a mean of six years. Patient and graft survival were evaluated and compared between patients who received a local donor liver and those who received an airplane transported donor liver. Predictors of survival were determined by univariate and multivariate analysis using cox regression. One hundred and ninety-three patients received a local donor liver and 93 patients received an airplane transported donor liver. Airplane transported livers had a significantly lower alanine transaminase (mean: 45 U/L vs 84 U/L, P = 0.035), higher donor risk index (mean: 1.88 vs 1.42, P airplane transport retained significance for graft loss (HR = 1.92, 95%CI: 1.16-3.17). One year graft survival was 0.88 for those with a local liver and was 0.71 for those with an airplane transported liver. One year graft loss was due to primary graft non-function or associated with preservation injury in 20.8% of recipients of an airplane transported liver compared with 4.6% in those with a local liver ( P = 0.027). Airplane transport of donor livers was independently associated with reduced graft survival following liver transplantation.

Public reactions to e-cigarette regulations on Twitter: a text mining analysis.

Science.gov (United States)

Lazard, Allison J; Wilcox, Gary B; Tuttle, Hannah M; Glowacki, Elizabeth M; Pikowski, Jessica

2017-12-01

In May 2016, the Food and Drug Administration (FDA) issued a final rule that deemed e-cigarettes to be within their regulatory authority as a tobacco product. News and opinions about the regulation were shared on social media platforms, such as Twitter, which can play an important role in shaping the public's attitudes. We analysed information shared on Twitter for insights into initial public reactions. A text mining approach was used to uncover important topics among reactions to the e-cigarette regulations on Twitter. SAS Text Miner V.12.1 software was used for descriptive text mining to uncover the primary topics from tweets collected from May 1 to May 17 2016 using NUVI software to gather the data. A total of nine topics were generated. These topics reveal initial reactions to whether the FDA's e-cigarette regulations will benefit or harm public health, how the regulations will impact the emerging e-cigarette market and efforts to share the news. The topics were dominated by negative or mixed reactions. In the days following the FDA's announcement of the new deeming regulations, the public reaction on Twitter was largely negative. Public health advocates should consider using social media outlets to better communicate the policy's intentions, reach and potential impact for public good to create a more balanced conversation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Management councils and regulation: public assistance in times of transition

Directory of Open Access Journals (Sweden)

Carla Cecília Rodrigues Almeida

2009-10-01

Full Text Available This article analyzes the role of municipal public assistance councils in the regulation of civil society organizations classified as social welfare organizations. We draw attention to the importance that these councils have for the operationalization of the more general principles governing the country’s social welfare/public assistance policies. Focusing on the regulatory role that management councils’ take on, we seek to understand, on the one hand, the wider institutional environment to which they belong and, on the other, their power to remodel a particular type of associativism which until very recently was identified and identified itself as philanthropical. Keywords: municipal councils, social welfare, Sistema Único de Assistência Social, regulation, public assistance entities.

Regulating Cannabis Manufacturing: Applying Public Health Best Practices from Tobacco Control.

Science.gov (United States)

Orenstein, Daniel G; Glantz, Stanton A

2018-01-01

State legalization and regulation of cannabis, despite continued federal illegality, is a massive shift in regulatory approach. Manufactured cannabis, including concentrates, extracts, edibles, tinctures, topicals and other products, has received less attention than more commonly used dried flower, but represents emerging regulatory challenges due to additives, potency, consumption methods, and abuse and misuse potential. In November 2017, the California Department of Public Health (CDPH) released initial cannabis manufacturing regulations as part of a new state regulatory structure. As the largest U.S. medical cannabis market (and largest legal adult use market in the world beginning in 2018), California's regulatory approach will potentially influence national and global policy. Comparing CDPH's initial regulations to tobacco control best practices reveals that, while the regulations recognize the need to protect public health, prioritizing public health over business interests requires stronger approaches to labeling, packaging, and product formulations. Based on tobacco best practices, we recommend that cannabis regulations incorporate large and proportionately sized informational labels, a prominent universal cannabis symbol, rotating and pictorial health warnings, mandatory plain packaging, a comprehensive ban on characterizing flavors and addictive additives, and strict limits on the potency of inhalable products and those easily confused with non-cannabis products.

Problems and Prospects: Public Health Regulation of Dietary Supplements.

Science.gov (United States)

Binns, Colin W; Lee, Mi Kyung; Lee, Andy H

2018-04-01

Dietary supplements are a global business worth more than US$100 billion annually. These supplements are taken by up to 50% of adults and perhaps one-third of children in economically advanced economies. Definitions of dietary supplements differ from country to country, and regulation is generally lax and often seems to be directed more toward promoting commerce than protecting public health. Supplements may directly cause toxic reactions or may interact with other supplements or pharmaceuticals. Some supplements are found to have been contaminated with heavy metals, and others do not contain the expected quantities of active ingredients. In general, supplements are not needed except in cases of established deficiencies, and excess of some nutrients can increase cancer rates. There are important public health reasons for taking some supplements, including folate and iodine in pregnancy. This review discusses the public health concerns associated with dietary supplements and suggests directions for further regulation.

Airplane dopes and doping

Science.gov (United States)

Smith, W H

1919-01-01

Cellulose acetate and cellulose nitrate are the important constituents of airplane dopes in use at the present time, but planes were treated with other materials in the experimental stages of flying. The above compounds belong to the class of colloids and are of value because they produce a shrinking action on the fabric when drying out of solution, rendering it drum tight. Other colloids possessing the same property have been proposed and tried. In the first stages of the development of dope, however, shrinkage was not considered. The fabric was treated merely to render it waterproof. The first airplanes constructed were covered with cotton fabric stretched as tightly as possible over the winds, fuselage, etc., and flying was possible only in fine weather. The necessity of an airplane which would fly under all weather conditions at once became apparent. Then followed experiments with rubberized fabrics, fabrics treated with glue rendered insoluble by formaldehyde or bichromate, fabrics treated with drying and nondrying oils, shellac, casein, etc. It was found that fabrics treated as above lost their tension in damp weather, and the oil from the motor penetrated the proofing material and weakened the fabric. For the most part the film of material lacked durability. Cellulose nitrate lacquers, however were found to be more satisfactory under varying weather conditions, added less weight to the planes, and were easily applied. On the other hand, they were highly inflammable, and oil from the motor penetrated the film of cellulose nitrate, causing the tension of the fabric to be relaxed.

Diagnosis and management of headache attributed to airplane travel.

Science.gov (United States)

Mainardi, Federico; Maggioni, Ferdinando; Lisotto, Carlo; Zanchin, Giorgio

2013-03-01

The headache attributed to airplane travel, also named "airplane headache", is characterized by the sudden onset of a severe head pain exclusively in relation to airplane flights, mainly during the landing phase. Secondary causes, such as upper respiratory tract infections or acute sinusitis, must be ruled out. Although its cause is not thoroughly understood, sinus barotrauma should be reasonably involved in the pathophysiological mechanisms. Furthermore, in the current International Classification of Headache Disorders, rapid descent from high altitude is not considered as a possible cause of headache, although the onset of such pain in airplane travellers or aviators has been well known since the beginning of the aviation era. On the basis of a survey we conducted with the courteous cooperation of people who had experienced this type of headache, we proposed diagnostic criteria to be added to the forthcoming revision of the International Classification of Headache Disorders. Their formal validation would favour further studies aimed at improving knowledge of the pathophysiological mechanisms involved and at implementing preventative measures.

Blended Buffet-Load-Alleviation System for Fighter Airplane

Science.gov (United States)

Moses, Robert W.

2005-01-01

The capability of modern fighter airplanes to sustain flight at high angles of attack and/or moderate angles of sideslip often results in immersion of part of such an airplane in unsteady, separated, vortical flow emanating from its forebody or wings. The flows from these surfaces become turbulent and separated during flight under these conditions. These flows contain significant levels of energy over a frequency band coincident with that of low-order structural vibration modes of wings, fins, and control surfaces. The unsteady pressures applied to these lifting surfaces as a result of the turbulent flows are commonly denoted buffet loads, and the resulting vibrations of the affected structures are known as buffeting. Prolonged exposure to buffet loads has resulted in fatigue of structures on several airplanes. Damage to airplanes caused by buffeting has led to redesigns of airplane structures and increased support costs for the United States Air Force and Navy as well as the armed forces of other countries. Time spent inspecting, repairing, and replacing structures adversely affects availability of aircraft for missions. A blend of rudder-control and piezoelectric- actuator engineering concepts was selected as a basis for the design of a vertical-tail buffet-load-alleviation system for the F/A-18 airplane. In this system, the rudder actuator is used to control the response of the first tail vibrational mode (bending at a frequency near 15 Hz), while directional patch piezoelectric actuators are used to control the second tail vibrational mode (tip torsion at a frequency near 45 Hz). This blend of two types of actuator utilizes the most effective features of each. An analytical model of the aeroservoelastic behavior of the airplane equipped with this system was validated by good agreement with measured results from a full-scale ground test, flight-test measurement of buffet response, and an in-flight commanded rudder frequency sweep. The overall performance of the

An Evaluation of Automatic Control System Concepts for General Aviation Airplanes

Science.gov (United States)

Stewart, E. C.

1990-01-01

A piloted simulation study of automatic longitudinal control systems for general aviation airplanes has been conducted. These automatic control systems were designed to make the simulated airplane easy to fly for a beginning or infrequent pilot. Different control systems are presented and their characteristics are documented. In a conventional airplane control system each cockpit controller commands combinations of both the airspeed and the vertical speed. The best system in the present study decoupled the airspeed and vertical speed responses to cockpit controller inputs. An important feature of the automatic system was that neither changing flap position nor maneuvering in steeply banked turns affected either the airspeed or the vertical speed. All the pilots who flew the control system simulation were favorably impressed with the very low workload and the excellent handling qualities of the simulated airplane.

Pratt, Joseph W.; Klebanoff, Leonard E.; Munoz-Ramos, Karina; Akhil, Abbas A.; Curgus, Dita B.; Schenkman, Benjamin L.

Highlights: ► We examine proton exchange membrane fuel cells on-board commercial airplanes. ► We model the added fuel cell system’s effect on overall airplane performance. ► It is feasible to implement an on-board fuel cell system with current technology. ► Systems that maximize waste heat recovery are the best performing. ► Current PEM and H 2 storage technology results in an airplane performance penalty. -- Abstract: Deployed on a commercial airplane, proton exchange membrane (PEM) fuel cells may offer emissions reductions, thermal efficiency gains, and enable locating the power near the point of use. This work seeks to understand whether on-board fuel cell systems are technically feasible, and, if so, if they could offer a performance advantage for the airplane when using today’s off-the-shelf technology. We also examine the effects of the fuel cell system on airplane performance with (1) different electrical loads, (2) different locations on the airplane, and (3) expected advances in fuel cell and hydrogen storage technologies. Through hardware analysis and thermodynamic simulation, we found that an additional fuel cell system on a commercial airplane is technically feasible using current technology. Although applied to a Boeing 787-type airplane, the method presented is applicable to other airframes as well. Recovery and on-board use of the heat and water that is generated by the fuel cell is an important method to increase the benefit of such a system. The best performance is achieved when the fuel cell is coupled to a load that utilizes the full output of the fuel cell for the entire flight. The effects of location are small and location may be better determined by other considerations such as safety and modularity. Although the PEM fuel cell generates power more efficiently than the gas turbine generators currently used, when considering the effect of the fuel cell system on the airplane’s overall performance we found that an overall

Reconfigurable multivariable control law for commercial airplane using a direct digital output feedback design

Science.gov (United States)

Ostroff, A. J.; Hueschen, R. M.

1984-01-01

The ability of a pilot to reconfigure the control surfaces on an airplane after a failure, allowing the airplane to recover to a safe condition for landing, becomes more difficult with increasing airplane complexity. Techniques are needed to stabilize and control the airplane immediately after a failure, allowing the pilot time to make longer range decisions. This paper shows a design of a discrete multivariable control law using four controls for the longitudinal channel of a B-737. Single control element failures are allowed in three of the four controls. The four controls design and failure cases are analyzed by means of a digital airplane simulation, with regard to tracking capability and ability to overcome severe windshear and turbulence during the aproach and landing phase of flight.

Board Diving Regulations in Public Swimming Pools and Risk of Injury.

Science.gov (United States)

Williams, David; Odin, Louise

2016-06-01

Public session access to diving boards is one of the stepping stones for those wishing to develop their skills in the sport of diving. The extent to which certain dive forms are considered risky (forward/backward/rotations) and therefore not permitted is a matter for local pool managers. In Study 1, 20 public pools with diving facilities responded to a U.K. survey concerning their diving regulation policy and related injury incidence in the previous year. More restrictive regulation of dive forms was not associated with a decrease in injuries (rs [42] = -0.20, p = 0.93). In Study 2, diving risk perception and attitudes towards regulation were compared between experienced club divers (N = 22) and nondivers (N = 22). Risk was perceived to be lower for those with experience, and these people favored less regulation. The findings are interpreted in terms of a risk thermostat model, where for complex physical performance activities such as diving, individuals may exercise caution in proportion to their ability and previous experience of success and failure related to the activity. Though intuitively appealing, restrictive regulation of public pool diving may be ineffective in practice because risk is not simplistically associated with dive forms, and divers are able to respond flexibly to risk by exercising caution where appropriate. © 2015 Society for Risk Analysis.

Deployed on a commercial airplane, proton exchange membrane fuel cells may offer emissions reductions, thermal efficiency gains, and enable locating the power near the point of use. This work seeks to understand whether on-board fuel cell systems are technically feasible, and, if so, if they offer a performance advantage for the airplane as a whole. Through hardware analysis and thermodynamic and electrical simulation, we found that while adding a fuel cell system using today's technology for the PEM fuel cell and hydrogen storage is technically feasible, it will not likely give the airplane a performance benefit. However, when we re-did the analysis using DOE-target technology for the PEM fuel cell and hydrogen storage, we found that the fuel cell system would provide a performance benefit to the airplane (i.e., it can save the airplane some fuel), depending on the way it is configured.

Investigation of control law reconfigurations to accommodate a control element failure on a commercial airplane

Science.gov (United States)

Ostroff, A. J.; Hueschen, R. M.

1984-01-01

The ability of a pilot to reconfigure the control surfaces on an airplane after a failure, allowing the airplane to recover to a safe condition, becomes more difficult with increasing airplane complexity. Techniques are needed to stabilize and control the airplane immediately after a failure, allowing the pilot more time to make longer range decisions. This paper presents a baseline design of a discrete multivariable control law using four controls for the longitudinal channel of a B-737. Non-reconfigured and reconfigured control laws are then evaluated, both analytically and by means of a digital airplane simulation, for three individual control element failures (stabilizer, elevator, spoilers). The simulation results are used to evaluate the effectiveness of the control reconfiguration on tracking ability during the approach and landing phase of flight with severe windshear and turbulence disturbing the airplane dynamics.

Investing in trust: nuclear regulators and the public

International Nuclear Information System (INIS)

2001-01-01

The workshop was held in Paris on the 29. November - 1. December 2000. Its objective was well captured in the title: Investing in Trust, Nuclear Regulators and the Public. The general public is concerned with the risks involved in the use of nuclear power, and has a legitimate desire for reliable and impartial information. It is important to convince the people that the regulatory body works for them and for their safety and is not promoting the use of nuclear energy or any other interests. A necessary condition for being trustworthy is to be well known, efficient channels are needed, a good information must be transferred to two directions, information must be easily available to the public are some important points developed in this workshop.

2007-01-01

Impact loads are considered in nuclear facility design as the result of the loading effects of certain design basis accidents and design basis threats made up of natural as well as man-made hazards. Also, beyond design basis accidents and threats are considered. Typical missiles include objects caused by tornado winds, aircrafts, war or terrorist activities, dropped objects, turbine fragments and other missiles resulting from failure of rotating equipment and whipping pipes and other objects of failure of pressurized fluid systems. The aim of the work is to study the potential of tools for numerical simulations to study the local load effects of airplane missiles impacting concrete structures. Two of the leading commercial computer codes for analysis of highly dynamic events, ABAQUS/Explicit and AUTODYN, have been evaluated. Numerical simulations have been carried out for rigid as well as deformable missiles with the characteristics of airplane engines. The analysis results have been compared with test results from a test program performed in the USA at Sandia National Laboratory and in Japan at Kobori Research Complex and Central Research Institute of the Electric Power industry. Finally, numerical simulations of a large passenger airliner impacting a reactor containment has been carried out using the analysis methodology developed. (author)

Flight Tests of a Ministick Controller in an F/A-18 Airplane

Science.gov (United States)

Stoliker, Patrick C.; Carter, John

2003-01-01

In March of 1999, five pilots performed flight tests to evaluate the handling qualities of an F/A-18 research airplane equipped with a small-displacement center stick (ministick) controller that had been developed for the JAS 39 Gripen airplane (a fighter/attack/ reconnaissance airplane used by the Swedish air force). For these tests, the ministick was installed in the aft cockpit (see figure) and production support flight control computers (PSFCCs) were used as interfaces between the controller hardware and the standard F/A-18 flight-control laws. The primary objective of the flight tests was to assess any changes in handling qualities of the F/A-18 airplane attributable to the mechanical characteristics of the ministick. The secondary objective was to demonstrate the capability of the PSFCCs to support flight-test experiments.

Advanced policy options to regulate sugar-sweetened beverages to support public health.

Pomeranz, Jennifer L

2012-02-01

Consumption of sugar-sweetened beverages (SSBs) has increased worldwide. As public health studies expose the detrimental impact of SSBs, consumer protection and public health advocates have called for increased government control. A major focus has been on restricting marketing of SSBs to children, but many innovative policy options--legally defensible ways to regulate SSBs and support public health--are largely unexplored. We describe the public health, economic, and retail marketing research related to SSBs (including energy drinks). We review policy options available to governments, including mandatory factual disclosures, earmarked taxation, and regulating sales, including placement within retail and food service establishments, and schools. Our review describes recent international initiatives and classifies options available in the United States by jurisdiction (federal, state, and local) based on legal viability.

Public utility regulation and national energy policy

Energy Technology Data Exchange (ETDEWEB)

Navarro, P.

1980-09-01

The linkage between Public Utility Commission (PUC) regulation, the deteriorating financial health of the electric utility industry, and implementation of national energy policy, particularly the reduction of foreign petroleum consumption in the utility sector is examined. The role of the Nation's utilities in the pursuit of national energy policy goals and postulates a linkage between PUC regulation, the poor financial health of the utility industry, and the current and prospective failure to displace foreign petroleum in the utility sector is discussed. A brief history of PUC regulation is provided. The concept of regulatory climate and how the financial community has developed a system of ranking regulatory climate in the various State jurisdictions are explained. The existing evidence on the hypothesis that the cost of capital to a utility increases and its availability is reduced as regulatory climate grows more unfavorable from an investor's point of view is analyzed. The implications of this cost of capital effect on the electric utilities and collaterally on national energy policy and electric ratepayers are explained. Finally various State, regional and Federal regulatory responses to problems associated with PUC regulation are examined.

A controls engineering approach for analyzing airplane input-output characteristics

Science.gov (United States)

Arbuckle, P. Douglas

1991-01-01

An engineering approach for analyzing airplane control and output characteristics is presented. State-space matrix equations describing the linear perturbation dynamics are transformed from physical coordinates into scaled coordinates. The scaling is accomplished by applying various transformations to the system to employ prior engineering knowledge of the airplane physics. Two different analysis techniques are then explained. Modal analysis techniques calculate the influence of each system input on each fundamental mode of motion and the distribution of each mode among the system outputs. The optimal steady state response technique computes the blending of steady state control inputs that optimize the steady state response of selected system outputs. Analysis of an example airplane model is presented to demonstrate the described engineering approach.

Nuclear regulator practices for communicating with the public

International Nuclear Information System (INIS)

Hayden, E.

2007-01-01

For decades, the U.S. Nuclear Regulatory Commission has communicated with members of the public so that they are aware of what the NRC does to protect them from the hazards of unnecessary radiation from nuclear power plants and other uses of radioactive material. Because the agency views nuclear regulation as the public's business, it should be transacted openly and candidly in order to maintain the public's confidence. The NRC recognizes that the public must be informed about, and have a reasonable opportunity to participate meaningfully in, the Agency's regulatory processes. The agency uses a variety of means to ensure openness in its regulatory process and thereby increasing public confidence. With rapidly expanding electronic capability, the agency has looked to new ways to reach out to the American public to let them know we are on the job overseeing nuclear safety. While we continue to communicate in some of the traditional ways - news releases, news conferences, briefing, speeches, Internet, brochures, and meetings - we are also exploring using blogs, mobile cell phone notifications, focus groups, open houses, and e-mail alerts to name a few.

Headache associated with airplane travel: a rare entity.

Science.gov (United States)

Cherian, Ajith; Mathew, Mini; Iype, Thomas; Sandeep, P; Jabeen, Afshan; Ayyappan, K

2013-01-01

Airplane travel headache is rare and has recently been described as a new form of headache associated with a specific situation. Of the 1,208 patients with primary headaches attending a tertiary care neurology hospital, two (0.16%) patients satisfied the criteria for headache related to airplane travel. Both the patients fulfilled the proposed diagnostic criteria for airplane travel headache. This unique headache had a mean duration of 24 minutes, localized to the medial supraorbital region described as having an intense jabbing or stabbing character that occurred exclusively and maximally during aircraft landing or take-off, following which pain intensity subsided . This rare headache felt on aircraft descent is probably due to the squeeze effect on the frontal sinus wall, when air trapped inside it contracts producing a negative pressure leading to mucosal edema, transudation and intense pain. Use of nasal decongestants either alone or in combination with naproxen sodium prior to ascent and descent abated the headache episodes. Awareness about this unique entity is essential to provide proper treatment and avoid patient suffering.

Full Text Available The reform of public service broadcasting (PSB faces many obstacles in countries with political transition such as Indonesia. After 1998-political change, the arrival of ideas to establish PSB in Indonesia in two decades lacks of appropriate policies. As in other transitional states in Eastern Europe, there is the lack of regulatory design as well as its implementation. This paper examines process of formulating PSB law in 2002, particularly pays attention to industry capture over the making process as a critical tool to observe a long-controvercial of broadcasting law revision process in Indonesia (2012-2016. By use public interest and capture theories in regulation, this paper answers why the outcome of PSB regulation is weak by observing how the law was made. This study provides new analysis on PSB media law that still rare in Indonesia. As independent and non-profit body, Indonesian PSB represented by RRI (Radio of the Republic Indonesia and TVRI (Television of the Republic Indonesia is protected by Broadcasting Act.32/2002. It was enacted in favor of two actors: authoritarian officials with interest to use PSB as their mouthpiece in one side and the industry groups with interest to apply free market policy on the other.

Science.gov (United States)

Kuhl, Christopher A.; Gayle, Steven W.; Hunter, Craig A.; Kenney, Patrick S.; Scola, Salvatore; Paddock, David A.; Wright, Henry S.; Gasbarre, Joseph F.

2009-01-01

A trade study was performed at NASA Langley Research Center under the Planetary Airplane Risk Reduction (PARR) project (2004-2005) to examine the option of using multiple, smaller thrusters in place of a single large thruster on the Mars airplane concept with the goal to reduce overall cost, schedule, and technical risk. The 5-lbf (22N) thruster is a common reaction control thruster on many satellites. Thousands of these types of thrusters have been built and flown on numerous programs, including MILSTAR and Intelsat VI. This study has examined the use of three 22N thrusters for the Mars airplane propulsion system and compared the results to those of the baseline single thruster system.

Assessment of community noise for a medium-range airplane with open-rotor engines

Kopiev, V. F.; Shur, M. L.; Travin, A. K.; Belyaev, I. V.; Zamtfort, B. S.; Medvedev, Yu. V.

2017-11-01

Community noise of a hypothetical medium-range airplane equipped with open-rotor engines is assessed by numerical modeling of the aeroacoustic characteristics of an isolated open rotor with the simplest blade geometry. Various open-rotor configurations are considered at constant thrust, and the lowest-noise configuration is selected. A two-engine medium-range airplane at known thrust of bypass turbofan engines at different segments of the takeoff-landing trajectory is considered, after the replacement of those engines by the open-rotor engines. It is established that a medium-range airplane with two open-rotor engines meets the requirements of Chapter 4 of the ICAO standard with a significant margin. It is shown that airframe noise makes a significant contribution to the total noise of an airplane with open-rotor engines at landing.

Report on the NRA workshop ''investing in trust, nuclear regulators and the public''

International Nuclear Information System (INIS)

Laaksonen, J.

2002-01-01

The workshop was held in Paris on the 29. November - 1. December 2000. Its objective was well captured in the title: Investing in Trust, Nuclear Regulators and the Public. The general public is concerned with the risks involved in the use of nuclear power, and has a legitimate desire for reliable and impartial information. The nuclear regulators have answers, but in order to fulfill the information needs of the general public and their elected representatives, they need to be regarded trustworthy. Most of the about 80 participants were from nuclear regulatory bodies and radiation protection agencies. The discussions gave regulators an opportunity to change views and experiences on how to gain trust in their openness and honesty, and in their will and capability to protect public interests. The weight given to the topic was indicated by participation of nine heads of national regulatory bodies, among them top regulators from four countries with largest nuclear programmes: the USA, Japan, France, and the UK. The number of papers presented was 33, and their topics were considered well chosen by the organizing committee. Throughout the workshop 'posters' were available; these were electronic links to the web sites of the attending regulatory bodies. Proceedings of the workshop will be published during the first half of 2001. (author)

Modeling the Aerodynamics and Performances of a Historic Airplane: the Spanish

Directory of Open Access Journals (Sweden)

A. González-Betes

2003-01-01

Full Text Available The process of modeling the aerodynamics and performances of a historic airplane is very similar to the conceptual and preliminary design phases of a new plane, with the advantage of knowing the configuration and that the airplane was airworthy; thus it is unnecessary to outline and assess many different alternatives. However, the drag polar, the real performances, stability features, etc, are still unknown. For various reasons (in particular because of two World Wars, or the Civil War in the Spanish case most details of many historical airplanes have been lost.In the present research work, the situation is as follows. In June 1933 the "Cuatro Vientos", a Spanish-built Bréguet XIX Super TR, flew non-stop from Seville to Cuba; a distance of 7500 km (about 4100 nautical miles in around 40 hours. A few days later, in a far less complicated stage between Havana and Mexico, the airplane was lost with its occupants to a storm in the Yucatan peninsula.The modeling considered in this paper starts by addressing the aerodynamic modifications introduced in the airplane for the extremely long flight. Then, with the help of old and present day aerodynamic data and methods the drag polar is estimated. The available engine data is completed and extrapolated to obtain information on power and fuel consumption. Finally, all this data is integrated to provide a reliable and technically sound reproduction of the Seville-Cuba flight.

The Food Industry and Self-Regulation: Standards to Promote Success and to Avoid Public Health Failures

Science.gov (United States)

Sharma, Lisa L.; Teret, Stephen P.

2010-01-01

Threatened by possible government regulation and critical public opinion, industries often undertake self-regulatory actions, issue statements of concern for public welfare, and assert that self-regulation is sufficient to protect the public. The food industry has made highly visible pledges to curtail children's food marketing, sell fewer unhealthy products in schools, and label foods in responsible ways. Ceding regulation to industry carries opportunities but is highly risky. In some industries (e.g., tobacco), self-regulation has been an abject failure, but in others (e.g., forestry and marine fisheries), it has been more successful. We examined food industry self-regulation in the context of other self-regulatory successes and failures and defined 8 standards that should be met if self-regulation is to be effective.

The Wind and Beyond: A Documentary Journey into the History of Aerodynamics in America. Volume 1; The Ascent of the Airplane

Science.gov (United States)

Hansen, James R. (Editor); Taylor, D. Bryan; Kinney, Jeremy; Lee, J. Lawrence

2003-01-01

This first volume, plus the succeeding five now in preparation, covers the impact of aerodynamic development on the evolution of the airplane in America. As the six-volume series will ultimately demonstrate, just as the airplane is a defining technology of the twentieth century, aerodynamics has been the defining element of the airplane. Volumes two through six will proceed in roughly chronological order, covering such developments as the biplane, the advent of commercial airliners, flying boats, rotary aircraft, supersonic flight, and hypersonic flight. This series is designed as an aeronautics companion to the Exploring the Unknown: Selected Documents in the History of the U.S. Civil Space Program (NASA SP-4407) series of books. As with Exploring the Unknown, the documents collected during this research project were assembled from a diverse number of public and private sources. A major repository of primary source materials relative to the history of the civil space program is the NASA Historical Reference Collection in the NASA Headquarters History Office. Historical materials housed at NASA field centers, academic institutions, and Presidential libraries were other sources of documents considered for inclusion, as were papers in the archives of private individuals and corporations.

Small-scale fixed wing airplane software verification flight test

Science.gov (United States)

Miller, Natasha R.

The increased demand for micro Unmanned Air Vehicles (UAV) driven by military requirements, commercial use, and academia is creating a need for the ability to quickly and accurately conduct low Reynolds Number aircraft design. There exist several open source software programs that are free or inexpensive that can be used for large scale aircraft design, but few software programs target the realm of low Reynolds Number flight. XFLR5 is an open source, free to download, software program that attempts to take into consideration viscous effects that occur at low Reynolds Number in airfoil design, 3D wing design, and 3D airplane design. An off the shelf, remote control airplane was used as a test bed to model in XFLR5 and then compared to flight test collected data. Flight test focused on the stability modes of the 3D plane, specifically the phugoid mode. Design and execution of the flight tests were accomplished for the RC airplane using methodology from full scale military airplane test procedures. Results from flight test were not conclusive in determining the accuracy of the XFLR5 software program. There were several sources of uncertainty that did not allow for a full analysis of the flight test results. An off the shelf drone autopilot was used as a data collection device for flight testing. The precision and accuracy of the autopilot is unknown. Potential future work should investigate flight test methods for small scale UAV flight.

2010-12-01

Headache with normal examinations and imaging, occurring during an airplane flight has been rarely reported. We present a young patient with a new type of headache that appeared during flights: take-off and landing of a plane and was not associated with other conditions. This airplane headache is rather rare in population and the pathophysiology of this type is not clear. Secondary causes must be ruled out before the diagnosis of a primary headache is made.

Headache Attributed to Airplane Travel: A Review of Literature.

Science.gov (United States)

Nierenburg, Hida; Jackfert, Katelin

2018-06-14

Headaches due to airplane travel are rare but documented in the literature. We aim to provide a review of diagnostic criteria and treatment for this condition. Several cases of this syndrome have been reported since it was first described in 2004. Airplane headache is classified as unilateral, stabbing, orbito-frontal pain, lasting under 30 min, and occurs during ascent or descent of a plane. Patients with this condition can develop anxiety and fear of flying given the intensity and severity of the pain. The pathophysiology of this syndrome is unknown, but theories include suspected barotrauma given changes in barometric pressure during ascent and descent. There are no randomized controlled trials regarding treatment, but case reports suggest headache prevention with pre-treatment with naproxen, decongestants, and triptans prior to air travel. Some non-pharmacological therapies reported include Valsalva maneuvers, chewing, relaxation techniques, and pressure at the pain area. As more cases of headache attributed to airplane travel are reported, epidemiological data can be obtained to further understand the incidence and prevalence of this condition, which can lead to improved treatment options for patients.

Smith, Robert E.; Bloor, Malcolm I. G.; Wilson, Michael J.; Thomas, Almuttil M.

2004-01-01

An efficient methodology is presented for defining a class of airplane configurations. Inclusive in this definition are surface grids, volume grids, and grid sensitivity. A small set of design parameters and grid control parameters govern the process. The general airplane configuration has wing, fuselage, vertical tail, horizontal tail, and canard components. The wing, tail, and canard components are manifested by solving a fourth-order partial differential equation subject to Dirichlet and Neumann boundary conditions. The design variables are incorporated into the boundary conditions, and the solution is expressed as a Fourier series. The fuselage has circular cross section, and the radius is an algebraic function of four design parameters and an independent computational variable. Volume grids are obtained through an application of the Control Point Form method. Grid sensitivity is obtained by applying the automatic differentiation precompiler ADIFOR to software for the grid generation. The computed surface grids, volume grids, and sensitivity derivatives are suitable for a wide range of Computational Fluid Dynamics simulation and configuration optimizations.

Response of equipment in nuclear power plants to airplane crash

International Nuclear Information System (INIS)

Schalk, M.; Woelfel, H.

1976-01-01

Nuclear power plants in Germany are to be designed against airplane crash. Two problems arise: first, the local problem of penetration as well as local destruction of the building and secondly the airplane induced vibrations of the whole building which cause loadings for secondary systems (equipment). This paper deals especially with the second problem. Floor response spectra due to airplane crash are presented for two different power plant buildings. The influence of various parameters (time history of excitation, direction and location of impact, mathematical model, soil, damping, etc.) are discussed. A comparison with the results of earthquake loading is given. Suggestions are made for developing suitable floor design spectra and using them to analyse multidegree-of-freedom systems. However, the paper gives only a partial answer to the questions arising because of some important restrictions which had to be made. Studies concerning these restrictions are still being conducted and will be presented in a separate paper. (Auth.)

Why do bacteria regulate public goods by quorum sensing? - How the shapes of cost and benefit functions determine the form of optimal regulation

Directory of Open Access Journals (Sweden)

Silja eHeilmann

2015-07-01

Full Text Available Many bacteria secrete compounds, which act as public goods. Such compounds are often under quorum sensing (QS regulation, yet it is not understood exactly when bacteria may gain from having a public good under QS regulation.Here, we show that the optimal public good production rate per cell as a function of population size (the optimal production curve, OPC depend crucially on the cost and benefit functions of the public good and that the OPC will fall into one of two categories: Either it is continuous or it jumps from zero discontinuously at a critical population size.If, e.g., the public good has accelerating returns and linear cost, then the OPC is discontinuous and the best strategy thus to ramp up production sharply at a precise population size.By using the example of public goods with accelerating and diminishing returns (and linear cost we are able to determine how the two different categories of OPSs, can best be matched by production regulated through a QS signal feeding back on its own production. We find that the optimal QS parameters are different for the two categories and specifically that public goods, which provide accelerating returns, call for stronger positive signal feedback.

Effects of road traffic background noise on judgments of individual airplane noises. Ph.D. Thesis

Powell, C. A.

1979-01-01

Two laboratory experiments were conducted to investigate the effects of road-traffic background noise on judgments of individual airplane flyover noises. In the first experiment, 27 subjects judged a set of 16 airplane flyover noises in the presence of traffic-noise sessions of 30-min duration consisting of the combinations of 3 traffic-noise types and 3 noise levels. In the second experiment, 24 subjects judged the same airplane flyover noises in the presence of traffic-noise sessions of 10-min duration consisting of the combinations of 2 traffic-noise types and 4 noise levels. In both experiments the airplane noises were judged less annoying in the presence of high traffic-noise levels than in the presence of low traffic-noise levels.

Patterns of measles transmission among airplane travelers.

Science.gov (United States)

Edelson, Paul J

2012-09-01

With advanced air handling systems on modern aircraft and the high level of measles immunity in many countries, measles infection in air travelers may be considered a low-risk event. However, introduction of measles into countries where transmission has been controlled or eliminated can have substantial consequences both for the use of public health resources and for those still susceptible. In an effort to balance the relatively low likelihood of disease transmission among largely immune travelers and the risk to the public health of the occurrence of secondary cases resulting from importations, criteria in the United States for contact investigations for measles exposures consider contacts to be those passengers who are seated within 2 rows of the index case. However, recent work has shown that cabin air flow may not be as reliable a barrier to the spread of measles virus as previously believed. Along with these new studies, several reports have described measles developing after travel in passengers seated some distance from the index case. To understand better the potential for measles virus to spread on an airplane, reports of apparent secondary cases occurring in co-travelers of passengers with infectious cases of measles were reviewed. Medline™ was searched for articles in all languages from 1946 to week 1 of March 2012, using the search terms "measles [human] or rubeola" and ("aircraft" or "airplane" or "aeroplane" or "aviation" or "travel" or "traveler" or "traveller"); 45 citations were returned. Embase™ was searched from 1988 to week 11 2012, using the same search strategy; 95 citations were returned. Papers were included in this review if they reported secondary cases of measles occurring in persons traveling on an airplane on which a person or persons with measles also flew, and which included the seating location of both the index case(s) and the secondary case(s) on the plane. Nine reports, including 13 index cases and 23 apparent secondary cases

Analysis of means of improving the uncontrolled lateral motions of personal airplanes

Science.gov (United States)

Mckinney, Marion O , Jr

1951-01-01

A theoretical analysis has been made of means of improving the uncontrolled motions of personal airplanes. The purpose of this investigation was to determine whether such airplanes could be made to fly uncontrolled for an indefinite period of time without getting into dangerous attitudes and for a reasonable period of time (1 to 3 min) without deviating excessively from their original course. The results of this analysis indicated that the uncontrolled motions of a personal airplane could be made safe as regards spiral tendencies and could be greatly improved as regards maintenance of course without resort to an autopilot. The only way to make the uncontrolled motions completely satisfactory as regards continuous maintenance of course, however, is to use a conventional type of autopilot.

The following is a summary: - Regulator commitments regarding public participation and experience gained in terms of effectiveness, visibility and credibility. The way the public hearings/meetings are organised and how they are used in the regulatory process. - How public participation is expected to be in the frame of the new proposed site selection procedure for radioactive waste disposal facility. This new process expects stakeholder involvement from the very beginning, even during the development of the site selection procedure itself, consisting of steps very precisely structured. - Regulator experience on responding to sensitive or 'high emotional' situations reminding the three main key-principles: (1) preparation to have an opportunity to have success; (2) always being honest, even during an 'emergency'; (3) start by understanding correctly the issue. - On how to speak about radioactivity to school children in the frame of an issue of a specific newspaper dedicated for children (8-12 years). Additional local actions in schools were also mentioned. (author)

Yue Kuizhi

2015-04-01

Full Text Available This paper studies the radar cross section (RCS of carrier electronic warfare airplanes. Under the typical naval operations section, the mathematical model of the radar wave’s pitch angle incidence range analysis is established. Based on the CATIA software, considering dynamic deflections of duck wing leading edge flaps, flaperons, horizontal tail, and rudder, as well as aircraft with air-to-air missile, anti-radiation missile, electronic jamming pod, and other weapons, the 3D models of carrier electronic warfare airplanes Model A and Model B with weapons were established. Based on the physical optics method and the equivalent electromagnetic flow method, by the use of the RCSAnsys software, the characteristics of carrier electronic warfare airplanes’ RCS under steady and dynamic flights were simulated under the UHF, X, and S radar bands. This paper researches the detection probability of aircraft by radars under the condition of electronic warfare, and completes the mathematical statistical analysis of the simulation results. The results show that: The Model A of carrier electronic warfare airplane is better than Model B on stealth performance and on discover probability by radar detection effectively.

Wierenga, Janelle; Thiede, Hanne; Helms, Leah; Hopkins, Sharon

2016-01-01

New regulations were implemented in King County, Washington, in 2010 requiring pet businesses to obtain a permit from Public Health-Seattle & King County (Public Health) and undergo annual inspections to provide education and ensure compliance with regulatory standards. The regulations were developed as a tool for zoonotic disease control and prevention education for businesses and their customers, as well as for environmental protection. To assess the acceptance, benefits, and challenges of the new regulations and identify ways for Public Health to improve educational efforts and assist businesses with compliance. Cross-sectional survey. King County, Washington. Pet businesses with Public Health permits in 2013. Self-administered survey responses. The response rate was 40.5%. The majority of respondents provided grooming, pet day care, and kennel/boarding services from small, independent businesses. Sixty-one percent reported Public Health inspections as beneficial, especially concerning disinfection procedures and using an infection control plan. Almost three-fourths of respondents used the Public Health template to develop the infection control plan. Forty-four percent reported using the educational materials provided by Public Health, and 62% used educational materials from other sources. Most respondents reported that they gained benefits from the pet business permit, although fewer agreed that they obtained a good value from the permit and fee. The most common benefits reported were protection of animal and human health and establishing the credibility of the pet business. Major challenges with the implementation of the pet business regulations were not generally reported by respondents. Most respondents reported a collaborative relationship between Public Health and the pet businesses. Improvements in infection control practices and positive responses to the inspections were reported by pet businesses. Survey results were used to improve infection control

This study aimed to gauge the Hong Kong's public support towards new e-cigarette regulation, and examine the associated factors of the support. We conducted a two-stage, randomized cross-sectional telephone-based survey to assess the public support towards the banning of e-cigarette promotion and advertisement, its use in smoke-free venues, the sale to people aged under 18, and regulating the sale of nicotine-free e-cigarettes. Adults (aged 15 years or above) who were never smoking ( n = 1706), ex-smoking ( n = 1712) or currently smoking ( n = 1834) were included. Over half (57.8%) supported all the four regulations. Banning of e-cigarette promotion and advertisement (71.7%) received slightly less support than the other three regulations (banning of e-cigarette use in smoke-free venues (81.5%); banning of e-cigarette sale to minors (93.9%); sale restriction of nicotine-free e-cigarettes (80.9%)). Current smokers, and perceiving e-cigarettes as less harmful than traditional cigarettes or not knowing the harmfulness, were associated with a lower level of support. Our findings showed a strong public support for further regulation of e-cigarettes in Hong Kong. Current stringent measures on tobacco and e-cigarettes, and media reports on the harmfulness of e-cigarettes may underpin the strong support for the regulation.

Headache attributed to airplane travel ('airplane headache'): clinical profile based on a large case series.

Science.gov (United States)

Mainardi, F; Lisotto, C; Maggioni, F; Zanchin, G

2012-06-01

The 'headache attributed to airplane travel', also named 'airplane headache' (AH), is a recently described headache disorder that appears exclusively in relation to airplane flights, in particular during the landing phase. Based on the stereotypical nature of the attacks in all reported cases, we proposed provisional diagnostic criteria for AH in a previously published paper. Up to now 37 cases have been described in the literature. After our paper was disseminated via the Internet, we received several email messages from subjects around the world who had experienced such a peculiar headache. Their cooperation, by completing a structured questionnaire and allowing the direct observation of three subjects, enabled us to carry out a study on a total of 75 patients suffering from AH. Our survey confirmed the stereotypical nature of the attacks, in particular with regard to the short duration of the pain (lasting less than 30 minutes in up to 95% of the cases), the clear relationship with the landing phase, the unilateral pain, the male preponderance, and the absence of accompanying signs and/or symptoms. It is conceivable to consider barotrauma as one of the main mechanisms involved in the pathophysiology of AH. The observation that the pain appears inconstantly in the majority of cases, without any evident disorder affecting the paranasal sinuses, could be consistent with a multimodal pathogenesis underlying this condition, possibly resulting in the interaction between anatomic, environmental and temporary concurrent factors. This is by far the largest AH case series ever reported in the literature. The diagnostic criteria that we previously proposed proved to be valid when applied to a large number of patients suffering from this condition. We support its recognition as a new form of headache, to be included in the forthcoming update of the International Headache Society Classification, within '10. Headache attributed to disorder of homoeostasis'. Its formal

Arumsari, Putri; Juliastuti; Khalifah Al'farisi, Muhammad

2017-12-01

One of the first tasks in starting a construction project is to estimate the total cost of building a project. In Indonesia there are several standards that are used to calculate the cost estimation of a project. One of the standards used in based on the Ministerial Regulation of Public Work No. 11/2013. However in a construction project, contractor often has their own cost estimation based on their own calculation. This research aimed to compare the construction project total cost using calculation based on the Ministerial Regulation of Public Work No. 11/2013 against the contractor’s calculation. Two projects were used as case study to compare the results. The projects were a 4 storey building located in Pantai Indah Kapuk area (West Jakarta) and a warehouse located in Sentul (West Java) which was built by 2 different contractors. The cost estimation from both contractors’ calculation were compared to the one based on the Ministerial Regulation of Public Work No. 11/2013. It is found that there were differences between the two calculation around 1.80 % - 3.03% in total cost, in which the cost estimation based on Ministerial Regulation was higher than the contractors’ calculations.

Regulation for the accomplishment of public purposes: the case of public utilities in Colombia

Since the 1990s, several countries in Latin America liberalized and privatized the public utilities business. As a consequence, there was a transit from the Entrepreneur State to the Regulatory State, the latter being traditionally understood as a model of regulation for competition, with a mayor concern only on economic objectives. Notwithstanding, the socioeconomic reality of Latin American countries, in particular Colombia, presented the fact that competition cannot be the only priority, a...

Performance of a Fuel-Cell-Powered, Small Electric Airplane Assessed

Science.gov (United States)

Berton, Jeffrey J.

2004-01-01

Rapidly emerging fuel-cell-power technologies may be used to launch a new revolution of electric propulsion systems for light aircraft. Future small electric airplanes using fuel cell technologies hold the promise of high reliability, low maintenance, low noise, and - with the exception of water vapor - zero emissions. An analytical feasibility and performance assessment was conducted by NASA Glenn Research Center's Airbreathing Systems Analysis Office of a fuel-cell-powered, propeller-driven, small electric airplane based on a model of the MCR-01 two-place kitplane (Dyn'Aero, Darois, France). This assessment was conducted in parallel with an ongoing effort by the Advanced Technology Products Corporation and the Foundation for Advancing Science and Technology Education. Their project - partially funded by a NASA grant - is to design, build, and fly the first manned, continuously propelled, nongliding electric airplane. In our study, an analytical performance model of a proton exchange membrane (PEM) fuel cell propulsion system was developed and applied to a notional, two-place light airplane modeled after the MCR-01 kitplane. The PEM fuel cell stack was fed pure hydrogen fuel and humidified ambient air via a small automotive centrifugal supercharger. The fuel cell performance models were based on chemical reaction analyses calibrated with published data from the fledgling U.S. automotive fuel cell industry. Electric propeller motors, rated at two shaft power levels in separate assessments, were used to directly drive a two-bladed, variable-pitch propeller. Fuel sources considered were compressed hydrogen gas and cryogenic liquid hydrogen. Both of these fuel sources provided pure, contaminant-free hydrogen for the PEM cells.

On the analytic and numeric optimisation of airplane trajectories under real atmospheric conditions

Science.gov (United States)

Gonzalo, J.; Domínguez, D.; López, D.

2014-12-01

From the beginning of aviation era, economic constraints have forced operators to continuously improve the planning of the flights. The revenue is proportional to the cost per flight and the airspace occupancy. Many methods, the first started in the middle of last century, have explore analytical, numerical and artificial intelligence resources to reach the optimal flight planning. In parallel, advances in meteorology and communications allow an almost real-time knowledge of the atmospheric conditions and a reliable, error-bounded forecast for the near future. Thus, apart from weather risks to be avoided, airplanes can dynamically adapt their trajectories to minimise their costs. International regulators are aware about these capabilities, so it is reasonable to envisage some changes to allow this dynamic planning negotiation to soon become operational. Moreover, current unmanned airplanes, very popular and often small, suffer the impact of winds and other weather conditions in form of dramatic changes in their performance. The present paper reviews analytic and numeric solutions for typical trajectory planning problems. Analytic methods are those trying to solve the problem using the Pontryagin principle, where influence parameters are added to state variables to form a split condition differential equation problem. The system can be solved numerically -indirect optimisation- or using parameterised functions -direct optimisation-. On the other hand, numerical methods are based on Bellman's dynamic programming (or Dijkstra algorithms), where the fact that two optimal trajectories can be concatenated to form a new optimal one if the joint point is demonstrated to belong to the final optimal solution. There is no a-priori conditions for the best method. Traditionally, analytic has been more employed for continuous problems whereas numeric for discrete ones. In the current problem, airplane behaviour is defined by continuous equations, while wind fields are given in a

The diversity of regulation and public financing of IVF in Europe and its impact on utilization.

Science.gov (United States)

Berg Brigham, K; Cadier, B; Chevreul, K

2013-03-01

How do the different forms of regulation and public financing of IVF affect utilization in otherwise similar European welfare state systems? Countries with more liberal social eligibility regulations had higher levels of IVF utilization, which diminished as the countries' policies became more restrictive. Europe is a world leader in the development and utilization of IVF, yet surveillance reveals significant differences in uptake among countries which have adopted different approaches to the regulation and and public financing of IVF. A descriptive and comparative analysis of legal restrictions on access to IVF in 13 of the EU15 countries that affirmatively regulate and publicly finance IVF. Using 2009 data from the European Society of Human Reproduction and Embryology study of regulatory frameworks in Europe and additional legislative research, we examined and described restrictions on access to IVF in terms of general eligibility, public financing and the scope of available services. Multiple correspondence analysis was used to identify patterns of regulation and groups of countries with similar regulatory patterns and to explore the effects on utilization of IVF, using data from the most recent European and international IVF monitoring reports. Regulations based on social characteristics of treatment seekers who are not applicable to other medical treatments, including relationship status and sexual orientation, appear to have the greatest impact on utilization. Countries with the most generous public financing schemes tend to restrict access to covered IVF to a greater degree. However, no link could be established between IVF utilization and the manner in which coverage was regulated or the level of public financing. Owing to the lack of data regarding the actual level of public versus private financing of IVF it is impossible to draw conclusions regarding equity of access. Moreover, the regulatory and utilization data were not completely temporally matched in

as a function of population size (the optimal production curve, OPC) depends crucially on the cost and benefit functions of the public good and that the OPC will fall into one of two categories: Either it is continuous or it jumps from zero discontinuously at a critical population size. If, e.g., the public...... good has accelerating returns and linear cost, then the OPC is discontinuous and the best strategy thus to ramp up production sharply at a precise population size. By using the example of public goods with accelerating and diminishing returns (and linear cost) we are able to determine how the two......Many bacteria secrete compounds which act as public goods.

Diabanna L. Post; Jérôme M. Da Ros

2003-01-01

This paper describes three cases of government-led efforts in France and the United States to bring stakeholders into the regulatory process for genetically-modified food. We analyze how government regulators, scientists, and members of the public interacted in these three different settings, and conclude that public participation is not linked with a regulatory outcome; in other words, for various reasons which we consider, public participation did not have a substantive impact on government...

Regulation for the accomplishment of public purposes: the case of public utilities in Colombia

OpenAIRE

Moreno, Luis Ferney

2016-01-01

Since the 1990s, several countries in Latin America liberalized and privatized the public utilities business. As a consequence, there was a transit from the Entrepreneur State to the Regulatory State, the latter being traditionally understood as a model of regulation for competition, with a mayor concern only on economic objectives. Notwithstanding, the socioeconomic reality of Latin American countries, in particular Colombia, presented the fact that competition cannot be the only priority, a...

Public Support for Electronic Cigarette Regulation in Hong Kong: A Population-Based Cross-Sectional Study

Directory of Open Access Journals (Sweden)

Yee Tak Derek Cheung

2017-06-01

Full Text Available This study aimed to gauge the Hong Kong’s public support towards new e-cigarette regulation, and examine the associated factors of the support. We conducted a two-stage, randomized cross-sectional telephone-based survey to assess the public support towards the banning of e-cigarette promotion and advertisement, its use in smoke-free venues, the sale to people aged under 18, and regulating the sale of nicotine-free e-cigarettes. Adults (aged 15 years or above who were never smoking (n = 1706, ex-smoking (n = 1712 or currently smoking (n = 1834 were included. Over half (57.8% supported all the four regulations. Banning of e-cigarette promotion and advertisement (71.7% received slightly less support than the other three regulations (banning of e-cigarette use in smoke-free venues (81.5%; banning of e-cigarette sale to minors (93.9%; sale restriction of nicotine-free e-cigarettes (80.9%. Current smokers, and perceiving e-cigarettes as less harmful than traditional cigarettes or not knowing the harmfulness, were associated with a lower level of support. Our findings showed a strong public support for further regulation of e-cigarettes in Hong Kong. Current stringent measures on tobacco and e-cigarettes, and media reports on the harmfulness of e-cigarettes may underpin the strong support for the regulation.

Public Regulation of the Use of Private Land : Opportunities and Challenges in Kenya

Directory of Open Access Journals (Sweden)

Nixon Sifuna

2009-06-01

Full Text Available In Kenya land is not only one of the most valuable belongings of any person, but a natural heritage that sustains all life forms and one that has to pass on from generation to generation by inheritance. Besides, land is a rather sensitive and emotive issue, for instance, having been central issue in the struggle for independence from colonialism. It is imperative therefore that land be used efficiently and responsibly to ensure it is available to posterity and in a form equitable and beneficial to the present as well as the future generations. Despite its importance, however, land in Kenya is a scarce resource that has to be available to competing uses and needs. It is also a resource whose use may result in environmental harm and degradation, jeopardise the interests of future generations in such land or negatively impact on its various uses. To ensure its efficient use and appropriate distribution of its benefits in the country, there is need for regulation of the use of any land irrespective of its regime of tenure in the public interest-whether is under state ownership, community (communal ownership or private ownership. The power to regulate the use of private land is generally vested in state and is usually exercised by public institutions and officers on behalf of the state and for the citizenry. Indeed a legitimate government especially that which has been popularly and democratically elected by the people is a custodian of the public interest and welfare of the citizens, with the mandate to act on their behalf. Apart from state and governmental entities, this regulation is also exercised by local management institutions, most of which are informal. Despite its beneficial value in terms of promoting the public good, the exercise of the power of public regulation of private land in Kenya faces numerous challenges. Indeed this power if properly employed can not only enforce and promote the public good but ensure sustainable land use

Can triptans safely be used for airplane headache?

Science.gov (United States)

Ipekdal, H Ilker; Karadaş, Ömer; Öz, Oğuzhan; Ulaş, Ümit H

2011-12-01

A few cases of airplane headache (AH) have been reported in the literature. Treatment strategies of AHs are also controversial. We followed-up five patients with AH. They were symptom-free during the daytime. Their physical, neurological, and ear-nose-throat examinations were all normal. Blood chemistries, cerebral magnetic resonance imaging, cerebral magnetic resonance imaging angiography, and paranasal sinus tomography studies of the patients were also normal. We preferred triptans because of the possible effect on the mechanism of AH. Patients were recommended to use single-dose of their drugs half an hour prior to flights. All of the patients had a good response to single dose triptan treatment and became headache-free during flights. This is the first study which puts forward the usefulness of the triptans as a safe treatment choice for airplane AH.

A Software Defined Radio Based Airplane Communication Navigation Simulation System

Science.gov (United States)

He, L.; Zhong, H. T.; Song, D.

2018-01-01

Radio communication and navigation system plays important role in ensuring the safety of civil airplane in flight. Function and performance should be tested before these systems are installed on-board. Conventionally, a set of transmitter and receiver are needed for each system, thus all the equipment occupy a lot of space and are high cost. In this paper, software defined radio technology is applied to design a common hardware communication and navigation ground simulation system, which can host multiple airplane systems with different operating frequency, such as HF, VHF, VOR, ILS, ADF, etc. We use a broadband analog frontend hardware platform, universal software radio peripheral (USRP), to transmit/receive signal of different frequency band. Software is compiled by LabVIEW on computer, which interfaces with USRP through Ethernet, and is responsible for communication and navigation signal processing and system control. An integrated testing system is established to perform functional test and performance verification of the simulation signal, which demonstrate the feasibility of our design. The system is a low-cost and common hardware platform for multiple airplane systems, which provide helpful reference for integrated avionics design.

Flight testing a propulsion-controlled aircraft emergency flight control system on an F-15 airplane

Science.gov (United States)

Burcham, F. W., Jr.; Burken, John; Maine, Trindel A.

1994-01-01

Flight tests of a propulsion-controlled aircraft (PCA) system on an F-15 airplane have been conducted at the NASA Dryden Flight Research Center. The airplane was flown with all flight control surfaces locked both in the manual throttles-only mode and in an augmented system mode. In the latter mode, pilot thumbwheel commands and aircraft feedback parameters were used to position the throttles. Flight evaluation results showed that the PCA system can be used to land an airplane that has suffered a major flight control system failure safely. The PCA system was used to recover the F-15 airplane from a severe upset condition, descend, and land. Pilots from NASA, U.S. Air Force, U.S. Navy, and McDonnell Douglas Aerospace evaluated the PCA system and were favorably impressed with its capability. Manual throttles-only approaches were unsuccessful. This paper describes the PCA system operation and testing. It also presents flight test results and pilot comments.

Exposure to tri-o-cresyl phosphate detected in jet airplane passengers

The aircraft cabin and flight deck ventilation are supplied from partially compressed unfiltered bleed air directly from the engine. Worn or defective engine seals can result in the release of engine oil into the cabin air supply. Aircrew and passengers have complained of illness following such “fume events”. Adverse health effects are hypothesized to result from exposure to tricresyl phosphate mixed esters, a chemical added to jet engine oil and hydraulic fluid for its anti-wear properties. Our goal was to develop a laboratory test for exposure to tricresyl phosphate. The assay was based on the fact that the active-site serine of butyrylcholinesterase reacts with the active metabolite of tri-o-cresyl phosphate, cresyl saligenin phosphate, to make a stable phosphorylated adduct with an added mass of 80 Da. No other organophosphorus agent makes this adduct in vivo on butyrylcholinesterase. Blood samples from jet airplane passengers were obtained 24–48 h after completing a flight. Butyrylcholinesterase was partially purified from 25 ml serum or plasma, digested with pepsin, enriched for phosphorylated peptides by binding to titanium oxide, and analyzed by mass spectrometry. Of 12 jet airplane passengers tested, 6 were positive for exposure to tri-o-cresyl phosphate that is, they had detectable amounts of the phosphorylated peptide FGEpSAGAAS. The level of exposure was very low. No more than 0.05 to 3% of plasma butyrylcholinesterase was modified. None of the subjects had toxic symptoms. Four of the positive subjects were retested 3 to 7 months following their last airplane trip and were found to be negative for phosphorylated butyrylcholinesterase. In conclusion, this is the first report of an assay that detects exposure to tri-o-cresyl phosphate in jet airplane travelers. -- Highlights: ► Travel on jet airplanes is associated with an illness, aerotoxic syndrome. ► A possible cause is exposure to tricresyl phosphate in engine lubricating oil. ► A blood

Parametric study of variation in cargo-airplane performance related to progression from current to spanloader designs

Science.gov (United States)

Toll, T. A.

1980-01-01

A parametric analysis was made to investigate the relationship between current cargo airplanes and possible future designs that may differ greatly in both size and configuration. The method makes use of empirical scaling laws developed from statistical studies of data from current and advanced airplanes and, in addition, accounts for payload density, effects of span distributed load, and variations in tail area ratio. The method is believed to be particularly useful for exploratory studies of design and technology options for large airplanes. The analysis predicts somewhat more favorable variations of the ratios of payload to gross weight and block fuel to payload as the airplane size is increased than has been generally understood from interpretations of the cube-square law. In terms of these same ratios, large all wing (spanloader) designs show an advantage over wing-fuselage designs.

Oblique-wing research airplane motion simulation with decoupling control laws

Science.gov (United States)

Kempel, Robert W.; Mc Neill, Walter E.; Maine, Trindel A.

1988-01-01

A large piloted vertical motion simulator was used to assess the performance of a preliminary decoupling control law for an early version of the F-8 oblique wing research demonstrator airplane. Evaluations were performed for five discrete flight conditions, ranging from low-altitude subsonic Mach numbers to moderate-altitude supersonic Mach numbers. Asymmetric sideforce as a function of angle of attack was found to be the primary cause of both the lateral acceleration noted in pitch and the tendency to roll into left turns and out of right turns. The flight control system was shown to be effective in generally decoupling the airplane and reducing the lateral acceleration in pitch maneuvers.

Analysis of an NPP Structure subjected to Vibrations Induced from Airplane Crashes

International Nuclear Information System (INIS)

Noh, Sang Hoon; Kim, Yong Soo; Kim, Chong Hak

2009-01-01

After the terrorists' attacks with civilian airplanes on September 11, 2001, special attention has been paid to the potential for an airplane crash into a Nuclear Power Plant (NPP) as a man-made hazard. An airplane crash (APC) into an NPP has the potential to damage the roofs and walls of these structures, as well as other systems and components such as pipelines, electric motors, power supplies, power cables of electricity transmission that are important for safety. Therefore, an evaluation of the structural response to an APC is important for the safety of NPPs to be confirmed. A structural integrity analysis was carried out focusing on the vibration effects of an APC on an NPP structure. The NPP structure under consideration has been conceptually redesigned based on APR1400 to have double containments for the purpose of a feasibility study to meet European requirements. The finite element method was used for the structural analysis of the NPP, and the computer code ABAQUS was employed for this analysis

Regulating public space on the beachfronts of Rio de Janeiro.

Science.gov (United States)

Godfrey, Brian J; Arguinzoni, Olivia M

2012-01-01

Despite the fortification of buildings, streets, and public squares, Rio de Janeiro's beaches remain widely regarded as democratic spaces of social diversity and accessibility. Our study revisits the question of Rio's “democratic” beachfronts, based on local interviews, field observations, official reports, and newspaper accounts. We focus on historical and contemporary perceptions of planning, privatization, and public-order programs on the city's southern seaside. Institutional discourses have justified increasing regulation to combat threats of disorder and insecurity. While residents value the relative openness of beachfronts, they also acknowledge issues of safety, social segmentation, and subtle forms of bias. The public generally applauds recent “Shock of Order” policing and commercial revitalization, although critics lament the loss of traditional freedoms for informal beach vendors and casual sports. These paradoxes highlight enduring tensions between social order and hierarchy on one hand, and democratic rights and equality on the other.

Emotion in obesity discourse: understanding public attitudes towards regulations for obesity prevention.

Science.gov (United States)

Farrell, Lucy C; Warin, Megan J; Moore, Vivienne M; Street, Jackie M

2016-05-01

Intense concern about obesity in the public imagination and in political, academic and media discourses has catalysed advocacy efforts to implement regulatory measures to reduce the occurrence of obesity in Australia and elsewhere. This article explores public attitudes towards the possible implementation of regulations to address obesity by analysing emotions within popular discourses. Drawing on reader comments attached to obesity-relevant news articles published on Australian news and current affairs websites, we examine how popular anxieties about the 'obesity crisis' and vitriol directed at obese individuals circulate alongside understandings of the appropriate role of government to legitimise regulatory reform to address obesity. Employing Ahmed's theorisation of 'affective economies' and broader literature on emotional cultures, we argue that obesity regulations achieve popular support within affective economies oriented to neoliberal and individualist constructions of obesity. These economies preclude constructions of obesity as a structural problem in popular discourse; instead positioning anti-obesity regulations as a government-endorsed vehicle for discrimination directed at obese people. Findings implicate a new set of ethical challenges for those championing regulatory reform for obesity prevention. © 2015 Foundation for the Sociology of Health & Illness.

A knowledge-based design framework for airplane conceptual and preliminary design

Science.gov (United States)

Anemaat, Wilhelmus A. J.

The goal of work described herein is to develop the second generation of Advanced Aircraft Analysis (AAA) into an object-oriented structure which can be used in different environments. One such environment is the third generation of AAA with its own user interface, the other environment with the same AAA methods (i.e. the knowledge) is the AAA-AML program. AAA-AML automates the initial airplane design process using current AAA methods in combination with AMRaven methodologies for dependency tracking and knowledge management, using the TechnoSoft Adaptive Modeling Language (AML). This will lead to the following benefits: (1) Reduced design time: computer aided design methods can reduce design and development time and replace tedious hand calculations. (2) Better product through improved design: more alternative designs can be evaluated in the same time span, which can lead to improved quality. (3) Reduced design cost: due to less training and less calculation errors substantial savings in design time and related cost can be obtained. (4) Improved Efficiency: the design engineer can avoid technically correct but irrelevant calculations on incomplete or out of sync information, particularly if the process enables robust geometry earlier. Although numerous advancements in knowledge based design have been developed for detailed design, currently no such integrated knowledge based conceptual and preliminary airplane design system exists. The third generation AAA methods are tested over a ten year period on many different airplane designs. Using AAA methods will demonstrate significant time savings. The AAA-AML system will be exercised and tested using 27 existing airplanes ranging from single engine propeller, business jets, airliners, UAV's to fighters. Data for the varied sizing methods will be compared with AAA results, to validate these methods. One new design, a Light Sport Aircraft (LSA), will be developed as an exercise to use the tool for designing a new airplane

Description of a Normal-Force In-Situ Turbulence Algorithm for Airplanes

Science.gov (United States)

Stewart, Eric C.

2003-01-01

A normal-force in-situ turbulence algorithm for potential use on commercial airliners is described. The algorithm can produce information that can be used to predict hazardous accelerations of airplanes or to aid meteorologists in forecasting weather patterns. The algorithm uses normal acceleration and other measures of the airplane state to approximate the vertical gust velocity. That is, the fundamental, yet simple, relationship between normal acceleration and the change in normal force coefficient is exploited to produce an estimate of the vertical gust velocity. This simple approach is robust and produces a time history of the vertical gust velocity that would be intuitively useful to pilots. With proper processing, the time history can be transformed into the eddy dissipation rate that would be useful to meteorologists. Flight data for a simplified research implementation of the algorithm are presented for a severe turbulence encounter of the NASA ARIES Boeing 757 research airplane. The results indicate that the algorithm has potential for producing accurate in-situ turbulence measurements. However, more extensive tests and analysis are needed with an operational implementation of the algorithm to make comparisons with other algorithms or methods.

Private governance, public purpose? Assessing transparency and accountability in self-regulation of food advertising to children.

Science.gov (United States)

Reeve, Belinda

2013-06-01

Reducing non-core food advertising to children is an important priority in strategies to address childhood obesity. Public health researchers argue for government intervention on the basis that food industry self-regulation is ineffective; however, the industry contends that the existing voluntary scheme adequately addresses community concerns. This paper examines the operation of two self-regulatory initiatives governing food advertising to children in Australia, in order to determine whether these regulatory processes foster transparent and accountable self-regulation. The paper concludes that while both codes appear to establish transparency and accountability mechanisms, they do not provide for meaningful stakeholder participation in the self-regulatory scheme. Accordingly, food industry self-regulation is unlikely to reflect public health concerns or to be perceived as a legitimate form of governance by external stakeholders. If industry regulation is to remain a feasible alternative to statutory regulation, there is a strong argument for strengthening government oversight and implementing a co-regulatory scheme.

Passenger Spaceplanes and Airplanes that Have Variable Configuration for Sonic Boom Reduction

Full Text Available In the last time, the interest for passenger space plane, supersonic passenger aircraft and supersonic business jets is increasing. For reducing sonic boom effects at ground level, some companies proposed airplanes having fuselage with small traversal section or having curved fuselage. This paper presents a new practical method for exciting vibrations in the leading edge of wing, tail and airplane's nose surfaces in order to scatter the shock wave and to reduce the sonic boom impact at ground level. The leading edges of wing, tail and airplane nose are covered with thin elastic fairings made of carbon fiber composite material which are separated through small gaps by the adjacent surfaces of wing, tail and nose. When the aircraft flies over populated areas, compressed air bleed from the engine compressors excites the vibration of carbon fiber fairings. The air is released through calibrated nozzles and directly impinges on the fairing surface generating their vibration. Thus, the shock waves are scattered and the impact of sonic boom on ground is much reduced.
