This book presents a detailed, self-contained theory of continuous mappings. It is mainly addressed to students who have already studied these mappings in the setting of metric spaces, as well as multidimensional differential calculus. The needed background facts about sets, metric spaces and linear algebra are developed in detail, so as to provide a seamless transition between students' previous studies and new material. In view of its many novel features, this book will be of interest also to mature readers who have studied continuous mappings from the subject's classical texts and wish to become acquainted with a new approach. The theory of continuous mappings serves as infrastructure for more specialized mathematical theories like differential equations, integral equations, operator theory, dynamical systems, global analysis, topological groups, topological rings and many more. In light of the centrality of the topic, a book of this kind fits a variety of applications, especially those that contribute to ...

Full Text Available Programs with control are usually modeled using lambda calculus extended with control operators. Instead of modifying lambda calculus, we consider a different model of computation. We introduce continuation calculus, or CC, a deterministic model of computation that is evaluated using only head reduction, and argue that it is suitable for modeling programs with control. It is demonstrated how to define programs, specify them, and prove them correct. This is shown in detail by presenting in CC a list multiplication program that prematurely returns when it encounters a zero. The correctness proof includes termination of the program. In continuation calculus we can model both call-by-name and call-by-value. In addition, call-by-name functions can be applied to call-by-value results, and conversely.

In this paper we consider the notion of continuous frame of subspaces and define a new concept of continuous frame, entitled continuous atomic resolution of identity, for arbitrary Hilbert space $\\mathcal{H}$ which has a countable reconstruction formula. Among the other results, we characterize the relationship between this new concept and other known continuous frames. Finally, we state and prove the assertions of the stability of perturbation in this concept.

Continuous models used in physics and other areas of mathematics applications become discrete when they are computerized, e.g., utilized for computations. Besides, computers are controlling processes in discrete spaces, such as films and television programs. At the same time, continuous models that are in the background of discrete representations use mathematical technology developed for continuous media. The most important example of such a technology is calculus, which is so useful in physics and other sciences. The main goal of this paper is to synthesize continuous features and powerful technology of the classical calculus with the discrete approach of numerical mathematics and computational physics. To do this, we further develop the theory of fuzzy continuous functions and apply this theory to functions defined on discrete sets. The main interest is the classical Intermediate Value theorem. Although the result of this theorem is completely based on continuity, utilization of a relaxed version of contin...
On barely continuous functions

Full Text Available The term barely continuous is a topological generalization of Baire-1 according to F. Gerlits of the Mathematical Institute of the Hungarian Academy of Sciences, and thus worthy of further study. This paper compares barely continuous functions and continuous functions on an elementary level. Knowing how the continuity of the identity function between topologies on a given set yields the lattice structure for those topologies, the barely continuity of the identity function between topologies on a given set is investigated and used to add to the structure of that lattice. Included are certain sublattices generated by the barely continuity of the identity function between those topologies. Much attention is given to topologies on finite sets.

In the field of program transformation, one often transforms programs into continuation-passing style to make their flow of control explicit, and then immediately removes the resulting continuations using defunctionalisation to make the programs first-order. In this article, we show how these two...... transformations can be fused together into a single transformation step that cuts out the need to first introduce and then eliminate continuations. Our approach is calculational, uses standard equational reasoning techniques, and is widely applicable....

Full Text Available The complementary log-log is an alternative to logistic model. In many areas of research, the outcome data are continuous. We aim to provide a procedure that allows the researcher to estimate the coefficients of the complementary log-log model without dichotomizing and without loss of information. We show that the sample size required for a specific power of the proposed approach is substantially smaller than the dichotomizing method. We find that estimators derived from proposed method are consistently more efficient than dichotomizing method. To illustrate the use of proposed method, we employ the data arising from the NHSI.

Continuous parallel coordinates.
Heinrich, Julian; Weiskopf, Daniel
2009-01-01
Typical scientific data is represented on a grid with appropriate interpolation or approximation schemes,defined on a continuous domain. The visualization of such data in parallel coordinates may reveal patterns latently contained in the data and thus can improve the understanding of multidimensional relations. In this paper, we adopt the concept of continuous scatterplots for the visualization of spatially continuous input data to derive a density model for parallel coordinates. Based on the point-line duality between scatterplots and parallel coordinates, we propose a mathematical model that maps density from a continuous scatterplot to parallel coordinates and present different algorithms for both numerical and analytical computation of the resulting density field. In addition, we show how the 2-D model can be used to successively construct continuous parallel coordinates with an arbitrary number of dimensions. Since continuous parallel coordinates interpolate data values within grid cells, a scalable and dense visualization is achieved, which will be demonstrated for typical multi-variate scientific data.

Continuous coal processing method
Ryason, P. R.
1980-06-01
A coal pump is provided in which solid coal is heated in the barrel of an extruder under pressure to a temperature at which the coal assumes plastic properties. The coal is continuously extruded, without static zones, using, for example, screw extrusion preferably without venting through a reduced diameter die to form a dispersed spray. As a result, the dispersed coal may be continuously injected into vessels or combustors at any pressure up to the maximum pressure developed in the extrusion device. The coal may be premixed with other materials such as desulfurization aids or reducible metal ores so that reactions occur, during or after conversion to its plastic state. Alternatively, the coal may be processed and caused to react after extrusion, through the die, with, for example, liquid oxidizers, whereby a coal reactor is provided.

Continuous Integration in CFMGR

Cfmgr is a managing tool for network devices. At the moment there is no way to automatically check the working behaviour of the tool, meaning that a lot of effort is spend into manually testing the tool after an update. During my stay at CERN I developed a black-box testing framework for Cfmgr according to Continuous Integration practices and successfully deployed the framework using Jenkins and Docker. This report discusses in detail how the framework works and how it can be conﬁgured, and equally gives a broad problem description and outlines future work directions.
Ethanol by continuous fermentation
Energy Technology Data Exchange (ETDEWEB)
1985-01-01
EtOH is produced by continuous fermentation of molasses. Thus, molasses diluted to 20/sup 0/ Brix was inoculated with bakers' yeast and fermented at 32/sup 0/. When the medium reached 4% EtOH, it was circulated through a centrifuge. The concentrated yeast was recycled to the fermentor and the supernatant was sent to a still. After distillation, the still residue was returned to the fermentor. When the initial charge was entirely fermented, 13 kg molasses of 40/sup 0/ Brix was added to the fermentor per hour, and the yield of EtOH was 1.7 kg/100 L-hour.

Continuous Shearlet Tight Frames
Grohs, Philipp
2010-10-22
Based on the shearlet transform we present a general construction of continuous tight frames for L2(ℝ2) from any sufficiently smooth function with anisotropic moments. This includes for example compactly supported systems, piecewise polynomial systems, or both. From our earlier results in Grohs (Technical report, KAUST, 2009) it follows that these systems enjoy the same desirable approximation properties for directional data as the previous bandlimited and very specific constructions due to Kutyniok and Labate (Trans. Am. Math. Soc. 361:2719-2754, 2009). We also show that the representation formulas we derive are in a sense optimal for the shearlet transform. © 2010 Springer Science+Business Media, LLC.

Continuously adjustable Pulfrich spectacles
Jacobs, Ken; Karpf, Ron
2011-03-01
A number of Pulfrich 3-D movies and TV shows have been produced, but the standard implementation has inherent drawbacks. The movie and TV industries have correctly concluded that the standard Pulfrich 3-D implementation is not a useful 3-D technique. Continuously Adjustable Pulfrich Spectacles (CAPS) is a new implementation of the Pulfrich effect that allows any scene containing movement in a standard 2-D movie, which are most scenes, to be optionally viewed in 3-D using inexpensive viewing specs. Recent scientific results in the fields of human perception, optoelectronics, video compression and video format conversion are translated into a new implementation of Pulfrich 3- D. CAPS uses these results to continuously adjust to the movie so that the viewing spectacles always conform to the optical density that optimizes the Pulfrich stereoscopic illusion. CAPS instantly provides 3-D immersion to any moving scene in any 2-D movie. Without the glasses, the movie will appear as a normal 2-D image. CAPS work on any viewing device, and with any distribution medium. CAPS is appropriate for viewing Internet streamed movies in 3-D.

With the rapid advances in medical science and increasing complexities of patient care, the need for continuing medical education (CME) is widely accepted by the profession. CME follows general and higher professional training, and should be a life long process. Teaching hospitals and postgraduate professional institutions play vital roles in organising, promoting, and monitoring this activity. CME directorates should be established. University authorities must recognise the important role of medical teachers in postgraduate and continuing medical education, and the staff establishment and terms of service should be held regularly. Medical libraries should have easy borrowing facilities. Self-assessment and audio-visual material are particularly helpful to the busy practitioner and inexpensive local or regional journals of quality can provide pertinent and up-to-date information. All charges for attending scientific meetings and educational material should be tax deductible or subsidized. The effectiveness of CME is difficult to assess and participation is almost impossible to enforce. Much depends on the standard of medical practice wanted by society. Recertification of general practitioners or specialists poses many problems. On the other hand, completion of self-assessment programmes, active participation at medical meetings, contributions to scientific literature, and membership of medical societies with built-in peer review could be monitored and regularly used to evaluate professional status.

2012-01-01
The Landsat Data Continuity Mission (LDCM) is a partnership formed between the National Aeronautics and Space Administration (NASA) and the U.S. Geological Survey (USGS) to place the next Landsat satellite in orbit in January 2013. The Landsat era that began in 1972 will become a nearly 41-year global land record with the successful launch and operation of the LDCM. The LDCM will continue the acquisition, archiving, and distribution of multispectral imagery affording global, synoptic, and repetitive coverage of the Earth's land surfaces at a scale where natural and human-induced changes can be detected, differentiated, characterized, and monitored over time. The mission objectives of the LDCM are to (1) collect and archive medium resolution (30-meter spatial resolution) multispectral image data affording seasonal coverage of the global landmasses for a period of no less than 5 years; (2) ensure that LDCM data are sufficiently consistent with data from the earlier Landsat missions in terms of acquisition geometry, calibration, coverage characteristics, spectral characteristics, output product quality, and data availability to permit studies of landcover and land-use change over time; and (3) distribute LDCM data products to the general public on a nondiscriminatory basis at no cost to the user.

The National High Magnetic Field Laboratory is completing a quasi-continuous magnet which will sustain a constant field of 60 T for 100 ms in a 32-mm 77 K bore. This magnet consists of 9 mechanically independent, nested, liquid nitrogen-cooled coils which are individually reinforced by high-strength stainless steel outer shells. The coils were wound from rectangular large cross-section, high-strength, high-conductivity copper conductor insulated wtih polyimide and fiberglass tapes. After winding, the coils were inserted into closely fitted, stainless steel reinforcing shells and impregnated with epoxy resin. Design, analysis, material, fabrication and operational issues for this class of magnets are reviewed. Fabrication and quality assurance testing of the 60 T coil set are covered in detail. Future growth of and possible links from this technology to other magnet systems are discussed. Needed improvements in design, analysis, materials, and fabrication are outlined.

An investigation was made of the employment of ketamin as the sole anaesthetic in general surgery, using continuous infusion of a 1% solution for both induction and maintenance in 118 cases. ECG was monitored and arterial pressure was measured invasively. Central venous pressure was also determined in 10 cases. Changes in serum enzyme values during and after surgery were examined in 35 patients. Blood samples were withdrawn before induction, after the return to consciousness, and 24 hr after the operation. Side-effects were common, but slight. Five patients suffered from nightmares, but these were persons with marked imaginative activity and a melancholic nature. Cardiocirculatory function was satisfactory. In particular, peripheral perfusion was excellent in all cases.

Spaces of continuous functions
Groenewegen, G L M
2016-01-01
The space C(X) of all continuous functions on a compact space X carries the structure of a normed vector space, an algebra and a lattice. On the one hand we study the relations between these structures and the topology of X, on the other hand we discuss a number of classical results according to which an algebra or a vector lattice can be represented as a C(X). Various applications of these theorems are given. Some attention is devoted to related theorems, e.g. the Stone Theorem for Boolean algebras and the Riesz Representation Theorem. The book is functional analytic in character. It does not presuppose much knowledge of functional analysis; it contains introductions into subjects such as the weak topology, vector lattices and (some) integration theory.

Entanglement Continuous Unitary Transformations
Sahin, S; Orus, R
2016-01-01
Continuous unitary transformations are a powerful tool to extract valuable information out of quantum many-body Hamiltonians, in which the so-called flow equation transforms the Hamiltonian to a diagonal or block-diagonal form in second quantization. Yet, one of their main challenges is how to approximate the infinitely-many coupled differential equations that are produced throughout this flow. Here we show that tensor networks offer a natural and non-perturbative truncation scheme in terms of entanglement. The corresponding scheme is called "entanglement-CUT" or eCUT. It can be used to extract the low-energy physics of quantum many-body Hamiltonians, including quasiparticle energy gaps. We provide the general idea behind eCUT and explain its implementation for finite 1d systems using the formalism of matrix product operators, and we present proof-of-principle results for the spin-1/2 1d quantum Ising model in a transverse field. Entanglement-CUTs can also be generalized to higher dimensions and to the thermo...

Oxygen therapy is defined as the therapeutic use of oxygen and consists of administering oxygen at higher concentrations than those found in room air, with the aim of treating or preventing hypoxia. This therapeutic intervention has been shown to increase survival in patients with chronic obstructive pulmonary disease (COPD) and respiratory failure. Although this concept has been extended by analogy to chronic respiratory failure caused by respiratory and non-respiratory diseases, continuous oxygen therapy has not been shown to be effective in other disorders. Oxygen therapy has not been shown to improve survival in patients with COPD and moderate hypoxaemia, nor is there consensus regarding its use during nocturnal desaturations in COPD or desaturations caused by effort. The choice of the oxygen source must be made on the basis of criteria such as technical issues, patient comfort and adaptability and cost. Flow must be adjusted to achieve appropriate transcutaneous oxyhaemoglobin saturation correction. Copyright © 2013 SEPAR. Published by Elsevier Espana. All rights reserved.

However, the model with periodic review and continuous ordering is highly relevant in practice, as information on the actual inventory level is not always up to date while making ordering decisions. This paper will therefore consider this case of periodic review and continuous ordering. Assuming zero fixed...

Exoplanets: The Hunt Continues!
2001-04-01
Swiss Telescope at La Silla Very Successful Summary The intensive and exciting hunt for planets around other stars ( "exoplanets" ) is continuing with great success in both hemispheres. Today, an international team of astronomers from the Geneva Observatory and other research institutes [1] is announcing the discovery of no less than eleven new, planetary companions to solar-type stars, HD 8574, HD 28185, HD 50554, HD 74156, HD 80606, HD 82943, HD 106252, HD 141937, HD 178911B, HD 141937, among which two new multi-planet systems . The masses of these new objects range from slightly less than to about 10 times the mass of the planet Jupiter [2]. The new detections are based on measured velocity changes of the stars [3], performed with the CORALIE spectrometer on the Swiss 1.2-m Leonard Euler telescope at the ESO La Silla Observatory , as well as with instruments on telescopes at the Haute-Provence Observatory and on the Keck telescopes on Mauna Kea (Hawaii, USA). Some of the new planets are unusual: * a two-planet system (around the star HD 82943) in which one orbital period is nearly exactly twice as long as the other - cases like this (refered to as "orbital resonance") are well known in our own solar system; * another two-planet system (HD 74156), with a Jupiter-like planet and a more massive planet further out; * a planet with the most elongated orbit detected so far (HD 80606), moving between 5 and 127 million kilometers from the central star; * a giant planet moving in an orbit around its Sun-like central star that is very similar to the one of the Earth and whose potential satellites (in theory, at least) might be "habitable". At this moment, there are 63 know exoplanet candidates with minimum masses below 10 Jupiter masses, and 67 known objects with minimum masses below 17 Jupiter masses. The present team of astronomers has detected about half of these. PR Photo 13a/01 : Radial-velocity measurements of HD 82943, a two-planet system . PR Photo 13b/01 : Radial
Continuous downstream processing of biopharmaceuticals.
Jungbauer, Alois
2013-08-01
Continuous manufacturing has been applied in many different industries but has been pursued reluctantly in biotechnology where the batchwise process is still the standard. A shift to continuous operation can improve productivity of a process and substantially reduce the footprint. Continuous operation also allows robust purification of labile biomolecules. A full set of unit operations is available to design continuous downstream processing of biopharmaceuticals. Chromatography, the central unit operation, is most advanced in respect to continuous operation. Here, the problem of 'batch' definition has been solved. This has also paved the way for implementation of continuous downstream processing from a regulatory viewpoint. Economic pressure, flexibility, and parametric release considerations will be the driving force to implement continuous manufacturing strategies in future.
Continuous verification using multimodal biometrics.
Sim, Terence; Zhang, Sheng; Janakiraman, Rajkumar; Kumar, Sandeep
2007-04-01
Conventional verification systems, such as those controlling access to a secure room, do not usually require the user to reauthenticate himself for continued access to the protected resource. This may not be sufficient for high-security environments in which the protected resource needs to be continuously monitored for unauthorized use. In such cases, continuous verification is needed. In this paper, we present the theory, architecture, implementation, and performance of a multimodal biometrics verification system that continuously verifies the presence of a logged-in user. Two modalities are currently used--face and fingerprint--but our theory can be readily extended to include more modalities. We show that continuous verification imposes additional requirements on multimodal fusion when compared to conventional verification systems. We also argue that the usual performance metrics of false accept and false reject rates are insufficient yardsticks for continuous verification and propose new metrics against which we benchmark our system.

Continued professional competence and portfolios.
Byrne, Michelle; Delarose, Teresa; King, Cecil A; Leske, Jane; Sapnas, Kathryn G; Schroeter, Kathryn
2007-01-01
It is traditionally assumed that licensure of healthcare professionals means that they are minimally competent. Many nursing specialty organizations offer examinations and other processes for certification, suggesting that certification is associated with continued competency. Can standardized examination for certification and continuing education for recertification ensure continued competency? Continuing education and testing provide a limited picture of an individual's knowledge and/or skill acquisition in a limited area at one point in time. However, portfolios promote critical thinking, self-assessment, and individual accountability. A portfolio is a portable mechanism for evaluating competencies that may otherwise be difficult to assess. This article summarizes some of the literature addressing portfolios, including aspects of portfolio development process, the value of portfolios versus continuing education for competency assessment, evidence associated with portfolio usage, and suggestions for organizing nursing portfolios.
Continuous cofinal maps on ultrafilters

2011-01-01
An ultrafilter $\\mathcal{U}$ on a countable base {\\em has continuous Tukey reductions} if whenever an ultrafilter $\\mathcal{V}$ is Tukey reducible to $\\mathcal{U}$, then every monotone cofinal map $f:\\mathcal{U}\\ra\\mathcal{V}$ is continuous when restricted to some cofinal subset of $\\mathcal{U}$. In the first part of the paper, we give mild conditions under which the property of having continuous Tukey reductions is inherited under Tukey reducibility. In particular, if $\\mathcal{U}$ is Tukey reducible to a p-point then $\\mathcal{U}$ has continuous Tukey reductions. In the second part, we show that any countable iteration of Fubini products of p-points has Tukey reductions which are continuous with respect to its topological Ramsey space of $\\vec{\\mathcal{U}}$-trees.
Protein design using continuous rotamers.
Directory of Open Access Journals (Sweden)
Pablo Gainza
2012-01-01
Full Text Available Optimizing amino acid conformation and identity is a central problem in computational protein design. Protein design algorithms must allow realistic protein flexibility to occur during this optimization, or they may fail to find the best sequence with the lowest energy. Most design algorithms implement side-chain flexibility by allowing the side chains to move between a small set of discrete, low-energy states, which we call rigid rotamers. In this work we show that allowing continuous side-chain flexibility (which we call continuous rotamers greatly improves protein flexibility modeling. We present a large-scale study that compares the sequences and best energy conformations in 69 protein-core redesigns using a rigid-rotamer model versus a continuous-rotamer model. We show that in nearly all of our redesigns the sequence found by the continuous-rotamer model is different and has a lower energy than the one found by the rigid-rotamer model. Moreover, the sequences found by the continuous-rotamer model are more similar to the native sequences. We then show that the seemingly easy solution of sampling more rigid rotamers within the continuous region is not a practical alternative to a continuous-rotamer model: at computationally feasible resolutions, using more rigid rotamers was never better than a continuous-rotamer model and almost always resulted in higher energies. Finally, we present a new protein design algorithm based on the dead-end elimination (DEE algorithm, which we call iMinDEE, that makes the use of continuous rotamers feasible in larger systems. iMinDEE guarantees finding the optimal answer while pruning the search space with close to the same efficiency of DEE.Software is available under the Lesser GNU Public License v3.

Intermittent redesign of continuous controllers
Gawthrop, Peter J.; Wang, Liuping
2010-08-01
The reverse-engineering idea developed by Maciejowski in the context of model-based predictive control is applied to the redesign of continuous-time compensators as intermittent controllers. Not only does this give a way of designing constrained input and state versions of continuous-time compensators but also provides a method for turning continuous-time compensators into event-driven versions. The procedure is illustrated by three examples: an event-driven PID controller relevant to the human balance control problem, a constrained version of the classical mechanical vibration absorber of den Hartog and an event driven and constrained vibration absorber.

Business continuity 2014: From traditional to integrated Business Continuity Management.
Ee, Henry
As global change continues to generate new challenges and potential threats to businesses, traditional business continuity management (BCM) slowly reveals its limitations and weak points to ensuring 'business resiliency' today. Consequently, BCM professionals also face the challenge of re-evaluating traditional concepts and introducing new strategies and industry best practices. This paper points to why traditional BCM is no longer sufficient in terms of enabling businesses to survive in today's high-risk environment. It also looks into some of the misconceptions about BCM and other stumbling blocks to establishing effective BCM today. Most importantly, however, this paper provides tips based on the Business Continuity Institute's (BCI) Good Practices Guideline (GPG) and the latest international BCM standard ISO 22301 on how to overcome the issues and challenges presented.
Continuous Approximations of a Class of Piecewise Continuous Systems
Danca, Marius-F.
In this paper, we provide a rigorous mathematical foundation for continuous approximations of a class of systems with piecewise continuous functions. By using techniques from the theory of differential inclusions, the underlying piecewise functions can be locally or globally approximated. The approximation results can be used to model piecewise continuous-time dynamical systems of integer or fractional-order. In this way, by overcoming the lack of numerical methods for differential equations of fractional-order with discontinuous right-hand side, unattainable procedures for systems modeled by this kind of equations, such as chaos control, synchronization, anticontrol and many others, can be easily implemented. Several examples are presented and three comparative applications are studied.
Coded continuous wave meteor radar
Vierinen, Juha; Chau, Jorge L.; Pfeffer, Nico; Clahsen, Matthias; Stober, Gunter
2016-03-01
The concept of a coded continuous wave specular meteor radar (SMR) is described. The radar uses a continuously transmitted pseudorandom phase-modulated waveform, which has several advantages compared to conventional pulsed SMRs. The coding avoids range and Doppler aliasing, which are in some cases problematic with pulsed radars. Continuous transmissions maximize pulse compression gain, allowing operation at lower peak power than a pulsed system. With continuous coding, the temporal and spectral resolution are not dependent on the transmit waveform and they can be fairly flexibly changed after performing a measurement. The low signal-to-noise ratio before pulse compression, combined with independent pseudorandom transmit waveforms, allows multiple geographically separated transmitters to be used in the same frequency band simultaneously without significantly interfering with each other. Because the same frequency band can be used by multiple transmitters, the same interferometric receiver antennas can be used to receive multiple transmitters at the same time. The principles of the signal processing are discussed, in addition to discussion of several practical ways to increase computation speed, and how to optimally detect meteor echoes. Measurements from a campaign performed with a coded continuous wave SMR are shown and compared with two standard pulsed SMR measurements. The type of meteor radar described in this paper would be suited for use in a large-scale multi-static network of meteor radar transmitters and receivers. Such a system would be useful for increasing the number of meteor detections to obtain improved meteor radar data products.

Discrete and Continuous Linearizable Equations
Lafortune, S; Ramani, A
1998-01-01
We study the projective systems in both continuous and discrete settings. These systems are linearizable by construction and thus, obviously, integrable. We show that in the continuous case it is possible to eliminate all variables but one and reduce the system to a single differential equation. This equation is of the form of those singled-out by Painlevé in his quest for integrable forms. In the discrete case, we extend previous results of ours showing that, again by elimination of variables, the general projective system can be written as a mapping for a single variable. We show that this mapping is a member of the family of multilinear systems (which is not integrable in general). The continuous limit of multilinear mappings is also discussed.
Continuous biodisel productions: A review
Directory of Open Access Journals (Sweden)
Stamenković Ivica S.
2009-01-01
Full Text Available Continuous biodiesel production on laboratory and industrial scale was analyzed, with focus on their advantages and disadvantages. Attention was paid to specific characteristics of industrial processes in order to point out the advanced technologies. The well-known base-catalyzed continuous biodiesel production processes are related to problems caused by the immiscibility of the reactants (alcohol and oil, application of relatively high operating temperature (usually the boiling temperature of alcohol or one near it and obtained yield of methyl ester yields lower than desired. One way to overcome these problems is to employ special reactor design favoring the emulsion process and increasing the overall rate of biodiesel production process, even at room temperature and atmospheric pressure. The second way is to apply heterogeneous catalysts in continuous processes, which will probably be the optimal approach to economically justified and environmentally friendly biodiesel production.

The Los Alamos National Laboratory (LANL) is a premier national security research institution, delivering scientific and engineering solutions for the nation's most crucial and complex problems. Our primary responsibility is to ensure the safety, security, and reliability of the nation's nuclear stockpile. LANL emphasizes worker safety, effective operational safeguards and security, and environmental stewardship, outstanding science remains the foundation of work at the Laboratory. In addition to supporting the Laboratory's core national security mission, our work advances bioscience, chemistry, computer science, earth and environmental sciences, materials science, and physics disciplines. To accomplish LANL's mission, we must ensure that the Laboratory EFs continue to be performed during a continuity event, including localized acts of nature, accidents, technological or attack-related emergencies, and pandemic or epidemic events. The LANL Continuity of Operations (COOP) Plan documents the overall LANL COOP Program and provides the operational framework to implement continuity policies, requirements, and responsibilities at LANL, as required by DOE 0 150.1, Continuity Programs, May 2008. LANL must maintain its ability to perform the nation's PMEFs, which are: (1) maintain the safety and security of nuclear materials in the DOE Complex at fixed sites and in transit; (2) respond to a nuclear incident, both domestically and internationally, caused by terrorist activity, natural disaster, or accident, including mobilizing the resources to support these efforts; and (3) support the nation's energy infrastructure. This plan supports Continuity of Operations for Los Alamos National Laboratory (LANL). This plan issues LANL policy as directed by the DOE 0 150.1, Continuity Programs, and provides direction for the orderly continuation of LANL EFs for 30 days of closure or 60 days for a pandemic/epidemic event. Initiation of COOP operations may

The latter allows the same receiver antennas to be used to receive multiple transmitters. The principles of the signal processing are discussed, in addition to discussion of several practical ways to increase computation speed, and how to optimally detect meteor echoes. Measurements from a campaign performed with a coded continuous wave SMR are shown and compared with two standard pulsed SMR measurements. The type of meteor radar described in this paper would be suited for use in a large scale multi-static network of meteor radar transmitters and receivers. This would, for example, provide higher spatio-temporal resolution for mesospheric wind field measurements.

Coded continuous wave meteor radar

The concept of a coded continuous wave specular meteor radar (SMR) is described. The radar uses a continuously transmitted pseudorandom phase-modulated waveform, which has several advantages compared to conventional pulsed SMRs. The coding avoids range and Doppler aliasing, which are in some cases problematic with pulsed radars. Continuous transmissions maximize pulse compression gain, allowing operation at lower peak power than a pulsed system. With continuous coding, the temporal and spectral resolution are not dependent on the transmit waveform and they can be fairly flexibly changed after performing a measurement. The low signal-to-noise ratio before pulse compression, combined with independent pseudorandom transmit waveforms, allows multiple geographically separated transmitters to be used in the same frequency band simultaneously without significantly interfering with each other. Because the same frequency band can be used by multiple transmitters, the same interferometric receiver antennas can be used to receive multiple transmitters at the same time. The principles of the signal processing are discussed, in addition to discussion of several practical ways to increase computation speed, and how to optimally detect meteor echoes. Measurements from a campaign performed with a coded continuous wave SMR are shown and compared with two standard pulsed SMR measurements. The type of meteor radar described in this paper would be suited for use in a large-scale multi-static network of meteor radar transmitters and receivers. Such a system would be useful for increasing the number of meteor detections to obtain improved meteor radar data products, such as wind fields. This type of a radar would also be useful for over-the-horizon radar, ionosondes, and observations of field-aligned-irregularities.
Continuous sampling of MSWI dioxins.
Hung, Pao-Chen; Chang, Shu-Hao; Buekens, Alfons; Chang, Moo-Been
2016-02-01
Municipal solid waste incineration (MSWI) is generally considered as a well-controlled source of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), in brief dioxins. Start-up conditions continue, however, to be problematic. A self-developed continuous sampler was specially designed and built to fulfill the various sampling criteria of U.S. EPA Method 23 and monitor the trends of dioxins emissions during diverse operating conditions. In the MSWI plant investigated, a 98.1% TEQ PCDD/F removal efficiency was achieved in normal operation using activated carbon injection + bag filtration (ACI + BF) and the corresponding PCDD/F emission remains well below the standard set by Taiwan EPA (0.1 ng I-TEQ/Nm(3) @ 11% O2). During start-up, however, continuous sampling indicates that this limit value is reached only after 12 and 9 days, respectively for the 1st (2011) and 2nd test campaign (2012). Only 15 days after start-up the PCDD/F emissions shrunk to the levels typically measured during normal operation. The PCDD/F emissions from the 1st and 2nd continuous sampling campaigns were 5.4 and 5.5 mg I-TEQ, respectively. Short-term PCDD/F sampling such as the U.S. EPA Method 23 is less adapted to monitor these transient PCDD/F emissions representatively and accurately, due to a steady decrease of PCDD/F emissions after start-up. This self-developed continuous sampler effectively enhances the ease and reliability of emission data collecting during transient conditions of MSWI.
Importance of Knowledge Continuity in Business Continuity Management
Hana Urbancová; Kateřina Venclová
2013-01-01
At present, the real generator of wealth in society, as well as in the economy as a whole, is knowledge. Knowledge that is critical and precious for an organization (whose loss would represent a threat for the organisation) and that is valuable for competitors needs to be treated with care. Knowledge continuity management is, also, applied to preserve critical knowledge in an organisation in situations where its holder leaves to join a competitor or to retire. The article aims to identify the...
Black holes by analytic continuation
Amati, Daniele
1997-01-01
In the context of a two-dimensional exactly solvable model, the dynamics of quantum black holes is obtained by analytically continuing the description of the regime where no black hole is formed. The resulting spectrum of outgoing radiation departs from the one predicted by the Hawking model in the region where the outgoing modes arise from the horizon with Planck-order frequencies. This occurs early in the evaporation process, and the resulting physical picture is unconventional. The theory predicts that black holes will only radiate out an energy of Planck mass order, stabilizing after a transitory period. The continuation from a regime without black hole formation --accessible in the 1+1 gravity theory considered-- is implicit in an S matrix approach and provides in this way a possible solution to the problem of information loss.
Personal continuous route pattern mining

Qian YE; Ling CHEN; Gen-cai CHEN
2009-01-01
In the daily life, people often repeat regular routes in certain periods. In this paper, a mining system is developed to find the continuous route patterns of personal past trips. In order to count the diversity of personal moving status, the mining system employs the adaptive GPS data recording and five data filters to guarantee the clean trips data. The mining system uses a client/server architecture to protect personal privacy and to reduce the computational load. The server conducts the main mining procedure but with insufficient information to recover real personal routes. In order to improve the scalability of sequential pattern mining, a novel pattern mining algorithm, continuous route pattern mining (CRPM), is proposed. This algorithm can tolerate the different disturbances in real routes and extract the frequent patterns. Experimental results based on nine persons' trips show that CRPM can extract more than two times longer route patterns than the traditional route pattern mining algorithms.
Continuous-variable quantum games
Energy Technology Data Exchange (ETDEWEB)
Li Hui; Du Jiangfeng; Massar, Serge
2002-12-30
We investigate the quantization of games in which the players can access to a continuous set of classical strategies, making use of continuous-variable quantum systems. For the particular case of the Cournot's duopoly, we find that, even though the two players both act as 'selfishly' in the quantum game as they do in the classical game, they are found to virtually cooperate due to the quantum entanglement between them. We also find that the original Einstein-Podolksy-Rosen state contributes to the best profits that the two firms could ever attain. Moreover, we propose a practical experimental setup for the implementation of such quantum games.
PIPER Continuous Adiabatic Demagnetization Refrigerator
Kimball, Mark O.; Shirron, Peter J.; Canavan, Edgar R.; James, Bryan L.; Sampson, Michael A.; Letmate, Richard V.
2017-01-01
We report upon the development and testing of a 4-stage adiabatic demagnetization refrigerator (ADR) capable of continuous cooling at 0.100 Kelvin. This cooler is being built to cool the detector array aboard NASA's Primordial Inflation Polarization Explorer (PIPER) observatory. The goal of this balloon mission is to measure the primordial gravitational waves that should exist if the theory of cosmological inflation is correct. At altitude, the ADR will hold the array of transition-edge sensors at 100 mK continuously while periodically rejecting heat to a 1.2 K pumped helium bath. During testing on ground, the array is held at the same temperature but heat is rejected to a 4.2 K helium bath indicating the flexibility in this coolers design.

Monolithic ceramic matrices containing many small flow passages useful as continuous-flow bioreactors. Ceramic matrix containing passages made by extruding and firing suitable ceramic. Pores in matrix provide attachment medium for film of cells and allow free movement of solution. Material one not toxic to micro-organisms grown in reactor. In reactor, liquid nutrients flow over, and liquid reaction products flow from, cell culture immobilized in one set of channels while oxygen flows to, and gaseous reaction products flow from, culture in adjacent set of passages. Cells live on inner surfaces containing flowing nutrient and in pores of walls of passages. Ready access to nutrients and oxygen in channels. They generate continuous high yield characteristic of immobilized cells, without large expenditure of energy otherwise incurred if necessary to pump nutrient solution through dense biomass as in bioreactors of other types.
Quantum teleportation with continuous measurements
Greplova, Eliska; Mølmer, Klaus; Andersen, Christian Kraglund
2016-10-01
We propose a scheme for quantum teleportation between two qubits, coupled sequentially to a cavity field. An implementation of the scheme is analyzed with superconducting qubits and a transmission line resonator, where measurements are restricted to continuous probing of the field leaking from the resonator rather than instantaneous projective Bell state measurement. We show that the past quantum state formalism S. Gammelmark, B. Julsgaard, and K. Mølmer, Phys. Rev. Lett. 111, 160401 (2013), 10.1103/PhysRevLett.111.160401 can be successfully applied to estimate what would have been the most likely Bell measurement outcome conditioned on our continuous signal record. This information determines which local operation on the target qubit yields the optimal teleportation fidelity. Our results emphasize the significance of applying a detailed analysis of quantum measurements in feedforward protocols in nonideal leaky quantum systems.
BRST theory for continuous spin
Bengtsson, Anders K. H.
2013-10-01
Some puzzling aspects of higher spin field theory in Minkowski space-time, such as the tracelessness constraints and the search for an underlying physical principle, are discussed. A connecting idea might be provided by the recently much researched continuous spin representations of the Poincaré group. The Wigner equations, treated as first class constraints, yields to a four-constraint BRST formulation. The resulting field theory, generalizing free higher spin field theory, is one among a set of higher spin theories that can be related to previous work on unconstrained formulations. In particular, it is conjectured that the unconstrained higher spin theory of Francia and Sagnotti is a limit of a continuous spin theory. Furthermore, a simple analysis of the constraint structure reveals a hint of a physical rationale behind the trace constraints.

Continuous-Variable Entanglement Swapping

Kevin Marshall
2015-05-01
Full Text Available We present a very brief overview of entanglement swapping as it relates to continuous-variable quantum information. The technical background required is discussed and the natural link to quantum teleportation is established before discussing the nature of Gaussian entanglement swapping. The limitations of Gaussian swapping are introduced, along with the general applications of swapping in the context of to quantum communication and entanglement distribution. In light of this, we briefly summarize a collection of entanglement swapping schemes which incorporate a non-Gaussian ingredient and the benefits of such schemes are noted. Finally, we motivate the need to further study and develop such schemes by highlighting requirements of a continuous-variable repeater.

Topological Photonics for Continuous Media
Silveirinha, Mario
Photonic crystals have revolutionized light-based technologies during the last three decades. Notably, it was recently discovered that the light propagation in photonic crystals may depend on some topological characteristics determined by the manner how the light states are mutually entangled. The usual topological classification of photonic crystals explores the fact that these structures are periodic. The periodicity is essential to ensure that the underlying wave vector space is a closed surface with no boundary. In this talk, we prove that it is possible calculate Chern invariants for a wide class of continuous bianisotropic electromagnetic media with no intrinsic periodicity. The nontrivial topology of the relevant continuous materials is linked with the emergence of edge states. Moreover, we will demonstrate that continuous photonic media with the time-reversal symmetry can be topologically characterized by a Z2 integer. This novel classification extends for the first time the theory of electronic topological insulators to a wide range of photonic platforms, and is expected to have an impact in the design of novel photonic systems that enable a topologically protected transport of optical energy.

Full Text Available A recurring proof obligation in modern mathematics, ranging from textbook exercises to deep research problems, is to show that a given function is a morphism in some category: in analysis and topology, for example, we frequently need to prove that functions are continuous, while in group theory we are constantly concerned with homomorphisms. This paper describes a generic procedure that automatically discharges routine instances of this kind of proof obligation in an interactive theorem prover. The proof procedure has been implemented and found very useful in a mathematical case studies carried out using the ProofPower system

This process constitutes the dilemma of change-stability, which can be tackled only through a vision of the future, meaning the idorganization of organization-environment interaction along with a flexible organizational structure, the use of advanced technology and the existence of a system of rewarding employees that reflects the values and priorities of both, organizational norms and individual needs.
Continuous-state branching processes
Li, Zenghu
2012-01-01
These notes were used in a short graduate course on branching processes the author gave in Beijing Normal University. The following main topics are covered: scaling limits of Galton--Watson processes, continuous-state branching processes, extinction probabilities, conditional limit theorems, decompositions of sample paths, martingale problems, stochastic equations, Lamperti's transformations, independent and dependent immigration processes. Some of the results are simplified versions of those in the author's book "Measure-valued branching Markov processes" (Springer, 2011). We hope these simplified results will set out the main ideas in an easy way and lead the reader to a quick access of the subject.
Continuing education for hospice staff.
Conedera, F; Schoessler, M
1985-06-01
Hospice nursing is unique because of the philosophy and issues surrounding hospice care. Program planning for hospice staff follows basic principles. The real challenge in developing programs for orientation, continuing, and inservice education is using a format that will truly enable staff to meet the objectives. A lecture, programmed instruction, or video/slide format works well for the "nuts and bolts," but more creativity is needed for the other issues facing the hospice nurse--death, grief, symptom control, stress, team roles, and helping patients with options. Incorporating into the program some of the methods suggested will offer staff the opportunity to become involved in learning and make that learning more meaningful.

Continuation-Passing C, compiling threads to events through continuations
Kerneis, Gabriel
2010-01-01
In this paper, we introduce Continuation Passing C (CPC), a programming language for concurrent systems in which native and cooperative threads are unified and presented to the programmer as a single abstraction. The CPC compiler uses a compilation technique, based on the CPS transform, that yields efficient code and an extremely lightweight representation for contexts. We provide a complete proof of the correctness of our compilation scheme. We show in particular that lambda-lifting, a common compilation technique for functional languages, is also correct in an imperative language like C, under some conditions enforced by the CPC compiler. The current CPC compiler is mature enough to write substantial programs such as Hekate, a highly concurrent BitTorrent seeder. Our benchmark results show that CPC is as efficient, while significantly cheaper, as the most efficient thread libraries available.
Continuous Precipitation of Ceria Nanoparticles from a Continuous Flow Micromixer
Energy Technology Data Exchange (ETDEWEB)
Tseng, Chih Heng; Paul, Brian; Chang, Chih-hung; Engelhard, Mark H.
2013-01-01
Cerium oxide nanoparticles were continuously precipitated from a solution of cerium(III) nitrate and ammonium hydroxide using a micro-scale T-mixer. Findings show that the method of mixing is important in the ceria precipitation process. In batch mixing and deposition, disintegration and agglomeration dominates the deposited film. In T-mixing and deposition, more uniform nanorod particles are attainable. In addition, it was found that the micromixing approach reduced the exposure of the Ce(OH)3 precipates to oxygen, yielding hydroxide precipates in place of CeO2 precipitates. Advantages of the micro-scale T-mixing approach include shorter mixing times, better control of nanoparticle shape and less agglomeration.
Continuous auditing: A literature review

2008-09-01
Full Text Available Recent fraud scandals involving highly known corporations like Enron, WorldCom, and Xerox have eroded public confidence in financial reporting. At the same time, the auditing profession has suffered a big hit. In this scenario, Continuous Auditing (CA seems to have emerged as a response to recover the credibility of the auditing profession as well as meeting Sarbanes-Oxley (SOX requirements. This study, that adopts an exploratory approach, analyzes the existing literature on this topic. First, we address the concepts, models and implications of CA. After, throughout a search on the journals indexed at the CAPES's Basis, a literature review is conducted. A total of 57 articles were selected. We analyze authorship, affiliation, publications, year and type of research of papers that have addressed CA. Findings evidence that most articles addressing CA are non-empirical and adopt a conceptual approach. Also, there is an increasing tendency of continuous auditing studies. Rutgers University seems to be the World's leading research center on CA. This study aims to contribute to the Accounting Science by evidencing possibilities for research and publication in CA.
Continuity properties of Moore cohomology
Austin, Tim
2010-01-01
In an important sequence of papers, Calvin Moore developed a version of group cohomology for locally compact groups taking into account their topology. He was able to re-establish most of the standard algebraic properties of group cohomology in the category of Polish Abelian modules for such groups, building initially on a bar resolution restricted to Borel cochains. However, the resulting cohomology groups can have rather unwieldy topological properties, and it remained mostly unclear whether they behave well under forming inverse limits of a sequence of base groups. This paper establishes that they are indeed continuous for such inverse limits for compact base groups and for a range of `nice' target modules, including all Banach spaces, discrete Abelian groups and tori when these are endowed with the trivial group action. In addition, this allows an extension of some results of Wigner identifying Moore's cohomology as isomorphic to alternatives constructed by other means, such as the Cech cohomology of the ...
Congenital syphilis: The continuing scourge.
Agrawal, Prachi G; Joshi, Rajesh; Kharkar, Vidya D; Bhaskar, M V
2014-01-01
Congenital syphilis is a severe, disabling infection that occurs due to the transmission of Treponema pallidum across the placenta during pregnancy or from contact with an infectious genital lesion during delivery. However, its early diagnosis is often difficult because more than half of the affected infants are asymptomatic, and the signs in symptomatic infants may be subtle and nonspecific. Although its incidence is declining, this long-forgotten disease continues to affect pregnant women, resulting in considerable perinatal morbidity and mortality. We hereby report a case of a 2-month-old infant with early congenital syphilis presenting with joint swellings and Parrot's pseudoparalysis, a comparative rarity in the present scenario. The report also stresses upon the importance of implementing the Centres for Disease Control and Prevention recommendation that all the pregnant women should be screened for syphilis in the first antenatal visit in the first trimester and again in late pregnancy.
Continuous improvement of software quality

1999-04-15
The present report is the first Halden Work Report delivered from the OECD Halden Reactor Project's research activity on formal methods and software quality. Of particular concern in this activity is to reach a consensus between regulators, licensees and the nuclear industry on questions related to the effective, industrial use of formal methods. The report gives considerable attention to the importance of continuous improvement as a characteristic of a living software quality system, and to the need of providing a basis for software process/product quality integration. In particular, the report discusses these aspects from the perspectives of defect prevention, formal methods, Total Quality Management (TQM), and Bayesian Belief Nets. Another concern is to promote controlled experiments on the use of new methods, techniques, and tools. This is achieved partly by reviewing suggestions on the collection and experimental use of data, and by surveying a number of metrics believed to have some potential for comparison studies (author) (ml)

2014-01-01
Continuing professional development (CPD) involves not only educational activities to enhance medical competence in medical knowledge and skills, but also in management, team building, professionalism, interpersonal communication, technology, teaching, and accountability. This paper aims at reviewing best practices to promote effective CPD. Principles and guidelines, as already defined by some professional societies and world organizations, are emphasized as core actions to best enhance an effective lifelong learning after residency. The personal learning plan (PLP) is discussed as the core of a well-structured CPD and we describe how it should be created. Fundamental CPD principles and how they are integrated in the framework of every physician's professional life will be described. The value of systematic and comprehensive CPD documentation and assessment is emphasized. Accreditation requirements and professional relationships with commercial sponsors are discussed.

Contra continuity and almost contra continuity in generalized fuzzy topological spaces
Bhattacharya, Baby; Chakraborty, Jayasree
2015-05-01
In this paper we introduce fuzzy contra continuity and almost contra continuity in generalized fuzzy topological space. Fuzzy almost contra continuity is weaker than fuzzy contra continuity in generalized fuzzy topological space. Then we investigate their characterizations and properties. We also established some equivalent relation on fuzzy contra continuity and fuzzy almost contra continuity in generalized fuzzy topological spaces.
Temporal yoking in continuous multitasking.
Jiang, Yuhong V; Swallow, Khena M
2014-12-01
Continuous tasks such as baggage screening often involve selective gating of sensory information when "targets" are detected. Previous research has shown that temporal selection of behaviorally relevant information triggers changes in perception, learning, and memory. However, it is unclear whether temporal selection has broad effects on concurrent tasks. To address this question, we asked participants to view a stream of faces and encoded faces of a particular gender for a later memory test. At the same time, they listened to a sequence of tones, pressing a button for specific pitched tones. We manipulated the timing of temporal selection such that target faces and target tones could be unrelated, perfectly correlated, or anticorrelated. Temporal selection was successful when the temporally coinciding stimuli were congruent (e.g., both were targets), but not when they were incongruent (i.e., only 1 was a target). This pattern suggests that attentional selection for separate tasks is yoked in time-when the attentional gate opens for 1 task it also opens for the other. Temporal yoking is a unique form of dual-task interaction.
Continued fractions and heavy sequences
Boshernitzan, Michael
2009-01-01
We initiate the study of the sets $H(c)$, $0=x-[x]$ stands for the fractional part of $x\\in \\mathbb R$. We prove that, for rational $c$, the sets $H(c)$ are of positive Hausdorff dimension and, in particular, are uncountable. For integers $m\\geq1$, we obtain a surprising characterization of the numbers $\\alpha\\in H_m= H(\\frac1m)$ in terms of their continued fraction expansions: The odd entries (partial quotients) of these expansions are divisible by $m$. The characterization implies that $x\\in H_m$ if and only if $\\frac 1{mx} \\in H_m$, for $x>0$. We are unaware of a direct proof of this equivalence, without making a use of the mentioned characterization of the sets $H_m$. We also introduce the dual sets $\\hat H_m$ of reals $y$ for which the sequence of integers $\\big([ky]\\big)_{k\\geq1}$ consistently hits the set $m\\mathbb Z$ with the at least expected frequency $\\frac1m$ and establish the connection with the sets $H_m$: {2mm} If $xy=m$ for $x,y>0$, then $x\\in H_m$ if and only if $y\\in \\hat H_m$.

Mennonites are Anabaptist communities that originated in Central Europe about 500 years ago. They initially migrated to different European countries, and in the early 18th century they established their first communities in North America, from where they moved to other American regions. We aimed to analyze an Argentinean Mennonite congregation from a genome-wide perspective by way of investigating >580.000 autosomal SNPs. Several analyses show that Argentinean Mennonites have European ancestry without signatures of admixture with other non-European American populations. Among the worldwide datasets used for population comparison, the CEU, which is the best-subrogated Central European population existing in The 1000 Genome Project, is the dataset showing the closest genome affinity to the Mennonites. When compared to other European population samples, the Mennonites show higher inbreeding coefficient values. Argentinean Mennonites show signatures of genetic continuity with no evidence of admixture with Americans of Native American or sub-Saharan African ancestry. Their genome indicates the existence of an increased endogamy compared to other Europeans most likely mirroring their lifestyle that involve small communities and historical consanguineous marriages.

The corrections system in the U.S. is supervising over five million offenders. This number is rising fast and so are the direct and indirect costs to society. To improve supervision and reduce the cost of parole and probation, first generation home arrest systems were introduced in 1987. While these systems proved to be helpful to the corrections system, their scope is rather limited because they only cover an offender at a single location and provide only a partial time coverage. To correct the limitations of first-generation systems, second-generation wide area continuous electronic offender monitoring systems, designed to monitor the offender at all times and locations, are now on the drawing board. These systems use radio frequency location technology to track the position of offenders. The challenge for this technology is the development of reliable personal locator devices that are small, lightweight, with long operational battery life, and indoors/outdoors accuracy of 100 meters or less. At the center of a second-generation system is a database that specifies the offender`s home, workplace, commute, and time the offender should be found in each. The database could also define areas from which the offender is excluded. To test compliance, the system would compare the observed coordinates of the offender with the stored location for a given time interval. Database logfiles will also enable law enforcement to determine if a monitored offender was present at a crime scene and thus include or exclude the offender as a potential suspect.
Metabolic effects of continuous feeding.
Wolever, T M
1990-09-01
To study the metabolic effects of slowing absorption, as a possible mechanism for the blood glucose and lipid-lowering effects of soluble fiber and low glycemic index (GI) foods, seven healthy men consumed a liquid formula diet either as three equal meals at 4-hour intervals, or by continuously sipping the same amount of formula over the 12-hour study period. Meal-related fluctuations of blood glucose, insulin, and triglycerides were seen during three meals, but not during sipping. Mean 12-hour levels of blood glucose and beta-hydroxybutyrate (beta OHB) were equivalent on sipping and three meals. The total integrated insulin area was reduced by 32% on sipping (P less than .01), but this was not explained by the 16% (NS) reduction in serum C-peptide response. Mean serum free fatty acid (FFA) and cholesterol levels were reduced by 20% and 2.6%, respectively (P less than .01). It is concluded that the reduced glycemic responses seen after soluble fiber-enriched meals and low GI foods can be explained by slow absorption. Although the overall mean daily blood glucose levels may not be reduced by slowing carbohydrate absorption in nondiabetic subjects, this is achieved at considerably lower ambient serum insulin concentrations. The reduction of insulin levels may be an important mechanism for the serum cholesterol-lowering effect of soluble fiber and low GI foods.
Continuously Connected With Mobile IP
2002-01-01
Cisco Systems developed Cisco Mobile Networks, making IP devices mobile. With this innovation, a Cisco router and its connected IP devices can roam across network boundaries and connection types. Because a mobile user is able to keep the same IP address while roaming, a live IP connection can be maintained without interruption. Glenn Research Center jointly tested the technology with Cisco, and is working to use it on low-earth-orbiting research craft. With Cisco's Mobile Networks functionality now available in Cisco IOS Software release 12.2(4)T, the commercial advantages and benefits are numerous. The technology can be applied to public safety, military/homeland security, emergency management services, railroad and shipping systems, and the automotive industry. It will allow ambulances, police, firemen, and the U.S. Coast Guard to stay connected to their networks while on the move. In the wireless battlefield, the technology will provide rapid infrastructure deployment for U.S. national defense. Airline, train, and cruise passengers utilizing Cisco Mobile Networks can fly all around the world with a continuous Internet connection.

BACKGROUND: During disasters, supply chain vulnerabilities, such as power, transportation, and communication, may affect the delivery of medications and medical supplies and hamper the ability to deliver critical care services. Disasters also have the potential to disrupt information technology (IT) in health-care systems, resulting in interruptions in patient care, particularly critical care, and other health-care business functions. The suggestions in this article are important for all of those involved in a large-scale pandemic or disaster with multiple critically ill or injured patients, including front-line clinicians, hospital administrators, and public health or government officials. METHODS: The Business and Continuity of Operations Panel followed the American College of Chest Physicians (CHEST) Guidelines Oversight Committee’s methodology in developing key questions regarding medication and supply shortages and the impact disasters may have on healthcare IT. Task force members met in person to develop the 13 key questions believed to be most relevant for Business and Continuity of Operations. A systematic literature review was then performed for relevant articles and documents, reports, and gray literature reported since 2007. No studies of sufficient quality were identified upon which to make evidence-based recommendations. Therefore, the panel developed expert opinion-based suggestions using a modified Delphi process. RESULTS: Eighteen suggestions addressing mitigation strategies for supply chain vulnerabilities including medications and IT were generated. Suggestions offered to hospitals and health system leadership regarding medication and supply shortages include: (1) purchase key medications and supplies from more than one supplier, (2) substituted medications or supplies should ideally be similar to those already used by an institution’s providers, (3) inventories should be tracked electronically to monitor medication/supply levels, (4) consider
Continuous profiling of magnetotelluric fields

The magnetotelluric (MT) method of mapping ground electrical conductivity is traditionally based on measurement of the surface impedance at widely spaced stations to infer models of the subsurface through a suitable pseudo 1-D inverse or with linearized least-squares inversion for 2- or 3-D geoelectric media. It is well known that small near-surface inhomogeneities can produce spatial discontinuities in the measured electric fields over a wide frequency range and may consequently bias the impedance on a very local scale. Inadequate station spacing effectively aliases the electric field measurements and results in distortions that cannot be removed in subsequent processing or modelling. In order to fully exploit the benefits of magnetotellurics in complex geological environments, closely spaced measurements must be used routinely. This thesis entertains an analysis of MT data taken along continuous profiles and is a first step that will allow more encompassing 2-D sampling techniques to become viable in the years to come. The developments presented here are to a large extent motivated by the physical insight gained from low-contrast solutions to the forward MT problem. These solutions describe the relationship between a perturbation in the electrical conductivity of the subsurface and the ensuing perturbation of the MT response as the output of a linear system. Albeit strictly accurate in a limited subset of practical exploration problems, the linearized solutions allow one to pursue a model independent study of the response characteristics of MT data. In fact, these solutions yield simple expressions for 1-,2-, and 3-D resistivity models which are here examined in progressive sequence.

Full Text Available After becoming the member state of the European Union, Lithuania undertook all the obligations of a member state. One of them is the implementation of The Lisbon Strategy aiming at the worlds most dynamic and competitive knowledge– based economy by 2010. Under the strategy, a stronger economy will drive job creation, sustainable development, and social inclusion. These changes demand the modernisation of education systems in the E U states, Lithuania among them. To achieve this objective, political forces came to an agreement on the future of Lithuanian education. In 2003 The Seimas of the Republic of Lithuania approved of National Education Strategy 2003–2012. This strategy is special not only because it is based on the experiences of the reform, addresses current and future world’s challenges and opportunities, maintains links with other strategic national reforms, but also emphasises efforts to ensure quality lifelong education for Lithuanian population and striving to become a partner in modern knowledge-based economy. Therefore, an extensive discussion on lifelong education strategies on individual and institution levels in all spheres of social and personal life has started in the E U and Lithuania. Nowadays lifelong learning is not just one aspect of education and training; it gradually is becoming the most important principle in the continuum of complex learning contexts. Such vision must be implemented this decade. The object of the research: the preconditions for the development of continuing adult education. The aim of the research: to examine the peculiarities of the preconditions for the development of continuing adult education in Pakruojis region. The methods of the research: analysis of references and documents on education; an anonymous survey in written form (a questionnaire; statistical analysis of data. The sample.

Mercury continuous emissions monitoring systems (CEMs) are being implemented in over 800 coal-fired power plant stacks throughput the U.S. Western Research Institute (WRI) is working closely with the Electric Power Research Institute (EPRI), the National Institute of Standards and Technology (NIST), and the Environmental Protection Agency (EPA) to facilitate the development of the experimental criteria for a NIST traceability protocol for dynamic elemental mercury vapor calibrators/generators. These devices are used to calibrate mercury CEMs at power plant sites. The Clean Air Mercury Rule (CAMR) which was published in the Federal Register on May 18, 2005 and vacated by a Federal appeals court in early 2008 required that calibration be performed with NIST-traceable standards. Despite the vacature, mercury emissions regulations in the future will require NIST traceable calibration standards, and EPA does not want to interrupt the effort towards developing NIST traceability protocols. The traceability procedures will be defined by EPA. An initial draft traceability protocol was issued by EPA in May 2007 for comment. In August 2007, EPA issued a conceptual interim traceability protocol for elemental mercury calibrators. The protocol is based on the actual analysis of the output of each calibration unit at several concentration levels ranging initially from about 2-40 {micro}g/m{sup 3} elemental mercury, and in the future down to 0.2 {micro}g/m{sup 3}, and this analysis will be directly traceable to analyses by NIST. The EPA traceability protocol document is divided into two separate sections. The first deals with the qualification of calibrator models by the vendors for use in mercury CEM calibration. The second describes the procedure that the vendors must use to certify the calibrators that meet the qualification specifications. The NIST traceable certification is performance based, traceable to analysis using isotope dilution inductively coupled plasma

The latest image from NASA's Jason oceanography satellite, taken during a 10-day collection cycle ending December 2, 2002, shows the Pacific dominated by two significant areas of higher-than-normal sealevel (warmer ocean temperatures). In the central equatorial Pacific, the large area of higher than normal sea surface heights(warmer than normal sea surface temperatures) associated with growing El Nino conditions has recently migrated eastward toward the coast of South America. Meanwhile, the influence of the 20- to 30-year larger than El Nino/La Nina pattern called the Pacific Decadal Oscillation continues to create warm, higher-than-normal sea-surface heights in the north Pacific that are connected in a warm horseshoe pattern with the western and southern Pacific. Sea-surface heights are a measure of how much heat is stored in the ocean below. This heat influences both present weather and future planetary climate events.The image shows red areas in the north Pacific and at the equator that are about 10 centimeters (4 inches) above normal; white areas indicate sea surface heights between 14 and 32 centimeters (6 to 13 inches) above normal. These regions contrast with the western tropical Pacific, where lower-than-normal sea levels (blue areas) have developed that are between 5 and 13 centimeters (2 and 5 inches) below normal, while purple areas range from 14 to 18 centimeters (6 to 7 inches) below normal. Along the equator, the red sea surface heights equate to sea surface temperature departures greater than one degree Celsius (two degrees Fahrenheit) and the white sea surface heights are sea surface temperatures 1.5 to 2.5 degrees Celsius(three to five degrees Fahrenheit) above normal.The U.S. portion of the Jason mission is managed by JPL for NASA's Earth Science Enterprise, Washington, D.C. Research on Earth's oceans using Jason and other space-based capabilities is conducted by NASA's Earth Science Enterprise to better understand and protect our home planet.

2014-01-01
We establish a new transcendence criterion of $p$-adic continued fractions which are called Ruban continued fractions. By this result, we give explicit transcendental Ruban continued fractions with bounded $p$-adic absolute value of partial quotients. This is $p$-adic analogy of Baker's result. We also prove that $p$-adic analogy of Lagrange Theorem for Ruban continued fractions is not true.

OBJECTIVES Despite the broad range of continuing medical education (CME) offerings aimed at educating practicing physicians through the provision of up-to-date clinical information, physicians commonly overuse, under-use, and misuse therapeutic and diagnostic interventions. It has been suggested that the ineffective nature of CME either accounts for the discrepancy between evidence and practice or at a minimum contributes to this gap. Understanding what CME tools and techniques are most effective in disseminating and retaining medical knowledge is critical to improving CME and thus diminishing the gap between evidence and practice. The purpose of this review was to comprehensively and systematically synthesize evidence regarding the effectiveness of CME and differing instructional designs in terms of knowledge, attitudes, skills, practice behavior, and clinical practice outcomes. REVIEW METHODS We formulated specific questions with input from external experts and representatives of the Agency for Healthcare Research and Quality (AHRQ) and the American College of Chest Physicians (ACCP) which nominated this topic. We systematically searched the literature using specific eligibility criteria, hand searching of selected journals, and electronic databases including: MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews, The Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Database of Abstracts of Reviews of Effects (DARE), PsycINFO, and the Educational Resource Information Center (ERIC). Two independent reviewers conducted title scans, abstract reviews, and then full article reviews to identify eligible articles. Each eligible article underwent double review for data abstraction and assessment of study quality. RESULTS Of the 68,000 citations identified by literature searching, 136 articles and 9 systematic reviews ultimately met our eligibility criteria. The overall quality of the literature was low and consequently firm conclusions were

This paper introduces the concept of semi-continuity of complex fuzzy functions, and discusses some of their elementary properties, such as the sum of two complex fuzzy functions of type I upper (lower)semi-continuity is type I upper (lower) semi-continuous, and the opposite of complex fuzzy functions of type I upper (lower) semi-continuity is type I lower (upper) semi-continuous. Based on some assumptions on two complex fuzzy functions of type I upper (lower) semi-continuity, it is shown that their product is type I upper (lower) semi-continuous. The paper also investigates the convergence of complex fuzzy functions. In particular, sign theorem, boundedness theorem, and Cauchy's criterion for convergence are kept. In this paper the metrics introduced by Zhang Guangquan was used. This paper gives a contribution to the study of complex fuzzy functions, and extends the corresponding work of Zhang Guangquan.

Internal factors influencing the knowledge continuity ensuring
Directory of Open Access Journals (Sweden)
Hana Urbancová
2012-01-01
Full Text Available The aim of the systematic ensuring of knowledge continuity is the continuity of an organisation’s development, the quality of managerial positions and the continuity of decision-making. By ensuring knowledge continuity, organisations may gain a performance-enhancing factor. The objective of the article is to identify the level of impact of decisive internal factors determining knowledge continuity ensuring and contributing to the efficiency of the organisations. Knowledge continuity ensuring as an internal force, however, can together with the right employees, help adapt more quickly to external conditions that organisations can hardly control. Monitoring and ensuring knowledge continuity can contribute to a higher quality of processes in general, in particular processes exploiting knowledge, and thus help improve the level of management. The first part of the article presents theoretical views on the aspects of knowledge continuity ensuring in organisations while the second part analyses the findings of the surveys carried out among managers in organisations in the Czech Republic. Based on the summary of the outcomes obtained it is possible to say that internal factors influence knowledge continuity ensuring in organisations, however, the level of impact of individual factors is determined by their size. The findings regarding the impact of each of the factors show that the most significant barriers to knowledge continuity ensuring are those associated with the human factor.
Midwifery continuity: The use of social media.
McCarthy, Rose; Choucri, Lesley; Ormandy, Paula; Brettle, Alison
2017-09-01
Continuity models of midwifery care improve women's experiences of care and clinical outcomes, but organisationally driven working practices do not facilitate a continuity model and the midwifery care received by most women is fragmented (Sandall et al., 2016, NHS England, 2016). Little is known about the potential for continuity of midwifery care to be achieved using an electronic platform. This paper examines the experiences of women accessing known midwives through a social media platform and their experiences and perception of continuity of care. The study forms part of a larger research project aiming to increase understanding about online social learning within professionally moderated social media based communities. This paper reports specifically the concept of midwifery continuity within the online communities. Two secret Facebook groups consisting of 31 mothers and 4 midwife moderators were created (17 mothers & 2 midwives / 14 mothers & 2 midwives). Primary data included 8 online and face to face focus groups, conducted at approximately 10 week intervals, and 28 individual one to one interviews with members of the online community within six weeks of giving birth. A thematic analysis using a priori themes was undertaken. This involved coding data which evidenced relational, informational and management continuity across the entire dataset (28 interviews and 8 focus groups). The analysis was undertaken broadly following the six stages described by Braun and Clarke (2006). Relational and informational continuity were identified across the data. Relational continuity was evident for both the participants and the midwife moderators; informational continuity was described by the participants. Management continuity was not identified. Continuity through social media use was valued by both the mothers and the midwives. Information and relational continuity needs of women can be met using professionally moderated, social media based groups. They may

We introduce a continuous weight attack strategy and numerically investigate the effect of continuous use a weight coefficient ω to define the attack intensity. The weight coefficient ω increases continuously from 1 to infinity, where 1 represents no attack and infinity represents complete destructive attack. Our results show that the continuous weight attack on two selected nodes with small ω (ω≈ 3) could achieve the same damage of complete elimination of a single selected node on both BA and ER networks. It is found that the continuous weight attack on a single selected edge with small ω (ω≈ 2) can reach the same effect of complete elimination of a single edge on BA network, but on ER network the damage of the continuous weight attack on a single edge is close to but always smaller than that of complete elimination of edge even if ω is very large.
Quantum engineering of continuous variable quantum states

2009-10-29
Quantum information with continuous variables is a field attracting increasing attention recently. In continuous variable quantum information one makes use of the continuous information encoded into the quadrature of a quantized light field instead of binary quantities such as the polarization state of a single photon. This brand new research area is witnessing exciting theoretical and experimental achievements such as teleportation, quantum computation and quantum error correction. The rapid development of the field is mainly due higher optical data rates and the availability of simple and efficient manipulation tools in continuous-variable quantum information processing. We in this thesis extend the work in continuous variable quantum information processing and report on novel experiments on amplification, cloning, minimal disturbance and noise erasure protocols. The promising results we obtain in these pioneering experiments indicate that the future of continuous variable quantum information is bright and many advances can be foreseen. (orig.)
Voltage stability, bifurcation parameters and continuation methods

Alvarado, F.L. [Wisconsin Univ., Madison, WI (United States)
1994-12-31
This paper considers the importance of the choice of bifurcation parameter in the determination of the voltage stability limit and the maximum power load ability of a system. When the bifurcation parameter is power demand, the two limits are equivalent. However, when other types of load models and bifurcation parameters are considered, the two concepts differ. The continuation method is considered as a method for determination of voltage stability margins. Three variants of the continuation method are described: the continuation parameter is the bifurcation parameter the continuation parameter is initially the bifurcation parameter, but is free to change, and the continuation parameter is a new `arc length` parameter. Implementations of voltage stability software using continuation methods are described. (author) 23 refs., 9 figs.
Business continuity management in international organisations.
Adamou, Christel
2014-01-01
In the area of business continuity management, a preliminary review of the literature reveals extensive knowledge, expertise and experience concerning organisations in the private and public sectors. It is interesting to note, however, that there is little literature about business continuity management in international organisations, although these entities are complex and particularly prone to threats. This apparent absence of literature suggests that business continuity management has not yet hit the agenda of international organisations. In recent years, member states have encouraged senior management to design and implement business continuity strategies to minimise the mishandling of an internal crisis and build organisational resilience, but very few of them have actually been able to design and implement comprehensive business continuity programmes. Based on actual experience working in international organisations, this paper outlines some of the challenges faced by international organisations in developing and implementing business continuity activities and attempts to make suggestions for further improvement.

In the end of the paper are presented some issues that organizations should take into consideration in the implementation of business continuity planning process projects.
Bayesian belief networks in business continuity.
Phillipson, Frank; Matthijssen, Edwin; Attema, Thomas
2014-01-01
Business continuity professionals aim to mitigate the various challenges to the continuity of their company. The goal is a coherent system of measures that encompass detection, prevention and recovery. Choices made in one part of the system affect other parts as well as the continuity risks of the company. In complex organisations, however, these relations are far from obvious. This paper proposes the use of Bayesian belief networks to expose these relations, and presents a modelling framework for this approach.
Retrospective turn continuations in Mandarin Chinese conversation
2007-01-01
How the status of further talk past the point of a turn's possible completion should he described, and what functions different kinds of turn continuation might serve - these are questions that have engaged many scholars since Sacks, Schegloff and Jefferson's turn-taking model (1974). In this paper, a general scheme is proposed with which one can tease out four interlocking strands in analyzing different kinds of turn continuation: Syntactic continuity vs. discontinuity, main vs. subordinate ...
Automatic penalty continuation in structural topology optimization
DEFF Research Database (Denmark)
Rojas Labanda, Susana; Stolpe, Mathias
2015-01-01
this issue is addressed. We propose an automatic continuation method, where the material penalization parameter is included as a new variable in the problem and a constraint guarantees that the requested penalty is eventually reached. The numerical results suggest that this approach is an appealing...... alternative to continuation methods. Automatic continuation also generally obtains better designs than the classical formulation using a reduced number of iterations....

Discrete continuous-phase superresolving filters.
Zhou, Sumei; Zhou, Changhe
2004-12-01
A new type of phase-only superresolving pupil filter with a discrete continuous-phase profile is presented that is a combination of discrete multilevel-phase modulation and continuous-phase modulation. This type of filter can achieve better superresolution performance than the continuous-phase filters reported in Opt. Lett. 28, 607 (2003). Therefore, with regard to the superresolution effect, this type of filter deserves study for practical applications. More importantly, the diffraction performance of this type of filter can explain the effect of a discrete-phase filter illuminated with a continuous wave front, whose superresolving performance cannot be analyzed with previous superresolution methods.
Measuring business continuity programmes in large organisations.
Green, Christopher
2014-01-01
In the field of business continuity management, organisations commit sums of money (often very large sums) to develop and maintain their continuity capability. Despite this, there is almost no measurement of whether this expense offers value for money, or whether it is targeted in the right areas. This paper will explain some methods of measuring components of a business continuity programme. The important outputs from this measurement activity are to demonstrate that an organisation's continuity capability is improving over time, and to identify areas of weakness that should be targeted during future work.

Continuity of care: differing conceptions and values.
Delva, Dianne; Kerr, Jonathan; Schultz, Karen
2011-08-01
To understand how the conception of continuity of care can influence family physician trainees by exploring the perspectives of established family physicians, physicians working in episodic care who had been trained in family medicine, and family medicine trainees. Qualitative analysis of focus group data. Southeastern Ontario. Seven focus groups consisting of members from 3 groups: established family physicians, physicians working in episodic care who had been trained in family medicine, or family medicine trainees. Semistructured focus group interviews were taped and transcribed. Using constant comparison, the transcripts were analyzed for themes related to continuity of care and how these were valued among the 3 groups of physicians. The 3 groups differed on how they valued continuity of the relationship, how they valued informational continuity, and how these concepts affected their perceptions of difficult clinician-patient relationships. Experienced family physicians described long-term relationships as a core value in their practices. In contrast, episodic care physicians valued informational continuity. Family medicine trainees learned about continuity of care through role models and theoretical teaching. They valued the efficiency gained by knowing patients and the reward of being recognized by patients. Family medicine trainees expressed greater distress with difficult clinician-patient interactions than experienced family physicians expressed. It was unclear whether the challenges of difficult relationships were offset by the trainees' appreciation of continuity of care. Different perceptions, settings, and skills can influence how continuity of care is valued, which might affect career and practice decisions among trainees.

Continuous hydrogen production from organic waste

Hydrogen is seen as a promising fuel for the future. Microbial fermentation of organic wastes is an attractive option. However, it has often been observed that hydrogen production in a continuously-fed reactor stops after a period of time. In this investigation, the effect of pH on lactic acid bacteria in continuous hydrogen production is studied. It was found that the antibiotic effect of the bacteria is prevented by keeping the pH greater than five. To establish what stops continuous hydrogen production, a continuous experiment was run using waste from bean curd manufacturing at a pH of 5.5 and a temperature of 35 degrees celsius. An increase in substrate concentration and the addition of nitrogen preferentially produced acetic and butyric acids and suppressed the production of propionic acid. Because of this, continuous hydrogen production was made possible. 4 refs., 5 tabs., 5 figs.
Continuous C*-algebras over topological spaces
Takeori, Mitsuharu
2010-01-01
We define continuous C*-algebras over a topological space X and establish some basic results. If X is a locally compact Hausdorff space, continuous C*-algebras over X are equivalent to ordinary continuous C_0(X)-algebras. The main purpose of our study is to prove that every continuous, full, separable, nuclear C*-algebra over X is KK(X)-equivalent to a stable Kirchberg algebra over X. (Here a Kirchberg algebra over X is a separable, nuclear, and strongly purely infinite C*-algebra over X with primitive ideal space homeomorphic to X.) In the case that X is a one-point space, this result is known as that every separable nuclear C*-algebra is KK-equivalent to a stable Kirchberg algebra. Moreover, as an intermediate result, we obtain the X-equivariant exact embedding result for continuous C*-algebras over X.
Extended Hamiltonian approach to continuous tempering.
Gobbo, Gianpaolo; Leimkuhler, Benedict J
2015-06-01
We introduce an enhanced sampling simulation technique based on continuous tempering, i.e., on continuously varying the temperature of the system under investigation. Our approach is mathematically straightforward, being based on an extended Hamiltonian formulation in which an auxiliary degree of freedom, determining the effective temperature, is coupled to the physical system. The physical system and its temperature evolve continuously in time according to the equations of motion derived from the extended Hamiltonian. Due to the Hamiltonian structure, it is easy to show that a particular subset of the configurations of the extended system is distributed according to the canonical ensemble for the physical system at the correct physical temperature.
Building a global business continuity programme.
Lazcano, Michael
2014-01-01
Business continuity programmes provide an important function within organisations, especially when aligned with and supportive of the organisation's goals, objectives and organisational culture. Continuity programmes for large, complex international organisations, unlike those for compact national companies, are more difficult to design, build, implement and maintain. Programmes for international organisations require attention to structural design, support across organisational leadership and hierarchy, seamless integration with the organisation's culture, measured success and demonstrated value. This paper details practical, but sometimes overlooked considerations for building successful global business continuity programmes.

A series of simulating experimental studies on the rheological behavior and its influential factors of aluminum alloy in continuous roll-casting process have been explored in this paper with a Gleeble-1500 Thermal-Mechanical Simulation Tester and a set of special clamp system. Relevant rheological rules in the process of coupling transient solidification and continuous deformation of roll-casting conditions are obtained. Experimental results indicate that four different characteristic stages exist in the whole rheological process, and relative constitutive models suitable for the given conditions of continuous roll casting process have been established through multivariable linear regression analysis of the experimental data.

Strategic continuity planning: the first critical step.
Smith, Jack
2013-01-01
Many companies (and business continuity professionals) believe a company needs a comprehensive, all-inclusive business continuity plan. Often they reach this conclusion after other companies or potential clients have requested to see their business continuity plan as a precondition of doing business. Companies without 'a plan' are then tempted to go out and hire a business continuity person and tell them to 'Create a plan!' This makes perfect sense to the executive team, but this approach will probably not work in a real event. This paper addresses the shortcomings of producing tactical documentation and calling it 'The Plan', and discusses ways to engage management in the development of a corporate strategy to be used during and after an event.
Bell inequalities with continuous angular variables
Borges, Carolina V S; Keller, Arne
2011-01-01
We consider bipartite quantum systems characterized by a continuous angular variable \\theta \\in [-\\pi, \\pi[, representing, for instance, the position of a particle on a circle. We show how to reveal non-locality on this type of system using inequalities similar to CHSH ones, originally derived for bipartite spin 1/2 like systems. Such inequalities involve correlated measurement of continuous angular functions and are equivalent to the continuous superposition of CHSH inequalities acting on bidimensional subspaces of the infinite dimensional Hilbert space. As an example, we discuss in detail one application of our results, and we derive inequalities based on orientation correlation measurements. The introduced Bell-type inequalities open the perspective of new and simpler experiments to test non locality on a variety of quantum systems described by continuous variables.

Full Text Available The paper addresses the problem of Discretization of continuous attributes in rough set. Discretization of continuous attributes is an important part of rough set theory because most of data that we usually gain are continuous data. In order to improve processing speed of discretization, we propose a FPGA-based discretization algorithm of continuous attributes making use of the speed advantage of FPGA. Combined attributes dependency degree of rough ret, the discretization system was divided into eight modules according to block design. This method can save much time of pretreatment in rough set and improve operation efficiency. Extensive experiments on a certain fighter fault diagnosis validate the effectiveness of the algorithm.

Achieving continuity: a story of stellar magnitude
Evans, Michael S.
2010-03-01
Scientists tell a story of 2,000 years of stellar magnitude research that traces back to Hipparchus. This story of continuity in practices serves an important role in scientific education and outreach. STS scholars point out many ways that stories of continuity, like many narratives about science, are disconnected from practices. Yet the story of continuity in stellar magnitude is a powerful scientific achievement precisely because of its connection to practice. The historical development of star catalogues shows how specific recording practices connected past and present in a useful way. The narrative of continuity in stellar magnitude, however else it might be subject to STS critique of narrative, maintains its power because of its connection to practice. I suggest that more attention be paid to connections between practice and narrative in STS, and in particular to the ways that historical practices sustain narratives by connecting past and present.

Continuous-variable quantum homomorphic signature
Li, Ke; Shang, Tao; Liu, Jian-wei
2017-10-01
Quantum cryptography is believed to be unconditionally secure because its security is ensured by physical laws rather than computational complexity. According to spectrum characteristic, quantum information can be classified into two categories, namely discrete variables and continuous variables. Continuous-variable quantum protocols have gained much attention for their ability to transmit more information with lower cost. To verify the identities of different data sources in a quantum network, we propose a continuous-variable quantum homomorphic signature scheme. It is based on continuous-variable entanglement swapping and provides additive and subtractive homomorphism. Security analysis shows the proposed scheme is secure against replay, forgery and repudiation. Even under nonideal conditions, it supports effective verification within a certain verification threshold.

1987-01-25
Cooked and uncooked continuous fermentation tests and a bench-scale continuous fermentation test were carried out using a flocculating yeast, beer yeast IFO-2018, and using molasses of various origin. Heat of fermentation was measured at the same time. High productivity was found in a non-cooking continuous fermentation, but lowering of a flocculating ability was a problem. A theoretical equation for calculating the heat of fermentation was introduced and its adaptability was examined. The continuous fermentation unit was a single tank type using a tower type fermentor. The fermentor had a capacity of 0.7 l actual volume, made of glass, and consisted of the two parts, a flowing part and a precipitation/separation part. The yeast used was Saccharomyces crevisiae IFO-2018 in comparison with such yeast as S. cerevisiae IFO-0224 and S. cervisiae EP-1. (7 figs,3 tabs,21 refs)

Continued Fraction as a Discrete Nonlinear Transform
Bender, C M; Bender, Carl M.; Milton, Kimball A.
1993-01-01
The connection between a Taylor series and a continued-fraction involves a nonlinear relation between the Taylor coefficients $\\{ a_n \\}$ and the continued-fraction coefficients $\\{ b_n \\}$. In many instances it turns out that this nonlinear relation transforms a complicated sequence $\\{a_n \\}$ into a very simple one $\\{ b_n \\}$. We illustrate this simplification in the context of graph combinatorics.

By alternating the polarity of the applied potential and producing reciprocating short rotations of at least one of the surfaces relative to the other, small increments of separation accumulate to cause substantial, useful segregation of electrophoretically separable components in a continuous flow system.
Process for fabricating continuous lengths of superconductor
Kroeger, Donald M.; List, III, Frederick A.
1998-01-01
A process for manufacturing a superconductor. The process is accomplished by depositing a superconductor precursor powder on a continuous length of a first substrate ribbon, overlaying a continuous length of a second substrate ribbon on said first substrate ribbon, and applying sufficient pressure to form a bound layered superconductor precursor between said first substrate ribbon and said second substrates ribbon. The layered superconductor precursor is then heat treated to form a super conductor layer.

Continuously-Variable Series-Elastic Actuator
Mooney, Luke M.; Herr, Hugh M.
2013-01-01
Actuator efficiency is an important factor in the design of powered leg prostheses, orthoses, exoskeletons, and legged robots. A continuously-variable series-elastic actuator (CV-SEA) is presented as an efficient actuator for legged locomotion. The CV-SEA implements a continuously-variable transmission (CVT) between a motor and series elastic element. The CVT reduces the torque seen at the motor and allows the motor to operate in speed regimes of higher efficiency, while the series-elastic el...
Continuous first order logic and local stability
Yaacov, Itaï Ben
2008-01-01
We develop continuous first order logic, a variant of the logic described in \\cite{Chang-Keisler:ContinuousModelTheory}. We show that this logic has the same power of expression as the framework of open Hausdorff cats, and as such extends Henson's logic for Banach space structures. We conclude with the development of local stability, for which this logic is particularly well-suited.
Carrier-free, continuous primary beer fermentation

Developing a sustainable continuous fermentation reactor is one of the most ambitious tasks in brewing science, but it could bring great benefits regarding volumetric productivity to modern breweries. Immobilized cell technology is often applied to reach the large densities of yeast needed in a continuous fermentation process. However, the financial cost associated with the use of carriers for yeast immobilization is one of the major drawbacks in the technology. This work suggests that yeast ...
Creating meaningful business continuity management programme metrics.
Strong, Brian
2010-11-01
The popular axiom, 'what gets measured gets done', is often applied in the quality management and continuous improvement disciplines. This truism is also useful to business continuity practitioners as they continually strive to prove the value of their organisation's investment in a business continuity management (BCM) programme. BCM practitioners must also remain relevant to their organisations as executives focus on the bottom line and maintaining stakeholder confidence. It seems that executives always find a way, whether in a hallway or elevator, to ask BCM professionals about the company's level of readiness. When asked, they must be ready with an informed response. The establishment of a process to measure business continuity programme performance and organisational readiness has emerged as a key component of US Department of Homeland Security 'Voluntary Private Sector Preparedness (PS-Prep) Program' standards where the overarching goal is to improve private sector preparedness for disasters and emergencies. The purpose of this paper is two-fold: to introduce continuity professionals to best practices that should be considered when developing a BCM metrics programme as well as providing a case study of how a large health insurance company researched, developed and implemented a process to measure BCM programme performance and company readiness.

Design Feature 7: Continuous Preclosure Ventilation
Energy Technology Data Exchange (ETDEWEB)
A.T. Watkins
1999-06-22
This design feature (DF) is intended to evaluate the effects of continuous ventilation in the emplacement drifts during preclosure and how the effects, if any, compare to the Viability Assessment (VA) reference design for postclosure long term performance. This DF will be evaluated against a set of criteria provided by the License Application Design Selection (LADS) group. The VA reference design included a continuous ventilation airflow quantity of 0.1 m{sup 3}/s in the emplacement drifts in the design of the repository subsurface facilities. The effects of this continuous ventilation during the preclosure was considered to have a negligible effect on postclosure performance and therefore is not included during postclosure in the assessment of the long term performance. This DF discusses the effects of continuous ventilation on the emplacement drift environment and surrounding rock conditions during preclosure for three increased airflow quantities. The three cases of continuous ventilation systems are: System A, 1.0 m{sup 3}/s (Section 8), System B, 5.0 m{sup 3}/s (Section 9), and System C, 10.0 m{sup 3}/s (Section 10) in each emplacement drift split. An emplacement drift split is half total length of emplacement drift going from the east or west main to the exhaust main. The difference in each system is the quantity of airflow in the emplacement drifts.
Manufacturing laser glass by continuous melting

A novel, continuous melting process is being used to manufacture meter-sized plates of laser glass at a rate 20-times faster, 5-times cheaper, and with 2-3 times better optical quality than with previous one-at-a-time, ''discontinuous'' technology processes. This new technology for manufacturing laser glass, which is arguably the most difficult continuously-melted optical material ever produced, comes as a result of a $60 million, six-year joint R&D program between government and industry. The glasses manufactured by the new continuous melting process are Nd-doped phosphate-based glasses and are marketed under the product names LG-770 (Schott Glass Technologies) and LHG-8 (Hoya Corporation USA). With this advance in glass manufacturing technology, it is now possible to construct high-energy, high-peak-power lasers for use in fusion energy development, national defense, and basic physics research that would have been impractical to build using the old melting technology. The development of continuously melted laser glass required technological advances that have lead to improvements in the manufacture of other optical glass products as well. For example, advances in forming, annealing, and conditioning steps of the laser glass continuous melting process are now being used in manufacture of other large-size optical glasses.
Continuity of care in community midwifery.
Bowers, John; Cheyne, Helen; Mould, Gillian; Page, Miranda
2015-06-01
Continuity of care is often critical in delivering high quality health care. However, it is difficult to achieve in community health care where shift patterns and a need to minimise travelling time can reduce the scope for allocating staff to patients. Community midwifery is one example of such a challenge in the National Health Service where postnatal care typically involves a series of home visits. Ideally mothers would receive all of their antenatal and postnatal care from the same midwife. Minimising the number of staff-handovers helps ensure a better relationship between mothers and midwives, and provides more opportunity for staff to identify emerging problems over a series of home visits. This study examines the allocation and routing of midwives in the community using a variant of a multiple travelling salesmen problem algorithm incorporating staff preferences to explore trade-offs between travel time and continuity of care. This algorithm was integrated in a simulation to assess the additional effect of staff availability due to shift patterns and part-time working. The results indicate that continuity of care can be achieved with relatively small increases in travel time. However, shift patterns are problematic: perfect continuity of care is impractical but if there is a degree of flexibility in the visit schedule, reasonable continuity is feasible.

Uijen, Annemarie A; Schers, Henk J; Schellevis, François G; Mokkink, Henk GA; van Weel, Chris; van den Bosch, Wil JHM
2012-01-01
Background Recently, the Nijmegen Continuity Questionnaire (NCQ) was developed. It aims to measure continuity of care from the patient perspective across primary and secondary care settings. Initial pilot testing proved promising. Aim To further examine the validity, discriminative ability, and reliability of the NCQ. Design A prospective psychometric instrument validation study in primary and secondary care in the Netherlands. Method The NCQ was administered to patients with a chronic disease recruited from general practice (n = 145) and hospital outpatient departments (n = 123) (response rate 76%). A principal component analysis was performed to confirm three subscales that had been found previously. Construct validity was tested by correlating the NCQ score to scores of other scales measuring quality of care, continuity, trust, and satisfaction. Discriminative ability was tested by investigating differences in continuity subscores of different subgroups. Test–retest reliability was analysed in 172 patients. Results Principal factor analysis confirmed the previously found three continuity subscales — personal continuity, care provider knows me; personal continuity, care provider shows commitment; and team/cross-boundary continuity. Construct validity was demonstrated through expected correlations with other variables and discriminative ability through expected differences in continuity subscores of different subgroups. Test–retest reliability was high (the intraclass correlation coefficient varied between 0.71 and 0.82). Conclusion This study provides evidence for the validity, discriminative ability, and reliability of the NCQ. The NCQ can be of value to identify problems in continuity of care. PMID:22782001
Continuous recovery system for electrorefiner system

2014-06-10
A continuous recovery system for an electrorefiner system may include a trough having a ridge portion and a furrow portion. The furrow portion may include a first section and a second section. An inlet and exit pipe may be connected to the trough. The inlet pipe may include an outlet opening that opens up to the first section of the furrow portion of the trough. The exit pipe may include an entrance opening that opens up to the second section of the furrow portion of the trough. A chain may extend through the inlet and exit pipes and along the furrow portion of the trough. The chain may be in a continuous loop form. A plurality of flights may be secured to the chain. Accordingly, the desired product may be continuously harvested from the electrorefiner system without having to halt the electrical power and/or remove the cathode and anode assemblies.
Discrete and continuous simulation theory and practice

It explores the connections between discrete and continuous simulation, and applies a specific focus to simulation in the supply chain and manufacturing field. It discusses the Monte Carlo simulation, which is the basic and traditional form of simulation. It addresses future trends and technologies for simulation, with par...
Lifted Inference for Relational Continuous Models
Choi, Jaesik; Hill, David J
2012-01-01
Relational Continuous Models (RCMs) represent joint probability densities over attributes of objects, when the attributes have continuous domains. With relational representations, they can model joint probability distributions over large numbers of variables compactly in a natural way. This paper presents a new exact lifted inference algorithm for RCMs, thus it scales up to large models of real world applications. The algorithm applies to Relational Pairwise Models which are (relational) products of potentials of arity 2. Our algorithm is unique in two ways. First, it substantially improves the efficiency of lifted inference with variables of continuous domains. When a relational model has Gaussian potentials, it takes only linear-time compared to cubic time of previous methods. Second, it is the first exact inference algorithm which handles RCMs in a lifted way. The algorithm is illustrated over an example from econometrics. Experimental results show that our algorithm outperforms both a groundlevel inferenc...

Full Text Available Formally capturing the transition from a continuous model to a discrete model is investigated using model based refinement techniques. A very simple model for stopping (eg. of a train is developed in both the continuous and discrete domains. The difference between the two is quantified using generic results from ODE theory, and these estimates can be compared with the exact solutions. Such results do not fit well into a conventional model based refinement framework; however they can be accommodated into a model based retrenchment. The retrenchment is described, and the way it can interface to refinement development on both the continuous and discrete sides is outlined. The approach is compared to what can be achieved using hybrid systems techniques.

2006-01-01
The relationship between major quality tools such as quality function development (QFD),failure mode and effects analysis (FMEA), design of experiments (DOE) and statistical process control (SPC) is analyzed through an extensive review of the literature and the concurrent quality engineering philosophy, and a basic structure for the integration of quality tools is presented. An integrated quality management system (IQMS) is developed using C++ Builder, nmning in the Windows 2000 Server environment with the basic internet connections, and SQL Server 2000 as the platform for developing the database. An illustrative example applying IQMS to the continuous quality improvement for a crane equipment manufacturing is reported. The result shows that the application of IQMS can optimize the process of design and manufacturing, shorten the cycle time of product, reduce the cost, and realize quality improvement continuously. The proposed integrated framework with IQMS is believed to be applicable to continuous quality improvement in many manufacturing companies.

Continuous retrieval of delayed Raman polaritons
Smartsev, Slava; Davidson, Nir; Firstenberg, Ofer
2016-01-01
We use a Raman four-wave mixing process to read out light from an atomic coherence which is continuously written. This realizes a continuous source of polaritons having been delayed or effectively stored for a finite duration. Contrary to slow-light delay, which depends on the atom number and population distribution, here the effective storage duration is determined solely by intensive properties of the system, approaching the ground-state natural lifetime at the weak driving limit. The generated polaritons are background free. We experimentally probe these properties utilizing spatial atomic diffusion as an 'internal clock' for the write-read delay. A continuous source of delayed polaritons can replace discrete write-read procedures when the atomic evolution is the subject of interest, for example, when dipolar interactions lead to retrieval of non-classical light.

2007-01-01
The development of computer controlled continuous rolling process calls for a mathematicalexpression that can express the inequality condition of "constant flow". Tension is the link of thecontinuous rolling process. From the condition of dynamic equilibrium, a differential equation oftension is given out. On the basis of the physical rules established from the industrial practice andexperimental studies, the law of volume constancy, the linear relation of forward slip and tension,the state equation of continuous rolling, the formula of dynamic tension, and the formula of statictension have been obtained. These formulae reflect the functional relations between tensions,thickness, roll velocity, and time in the continuous rolling process. It is implied that the continuousrolling process is a gradually steady, controllable, and measurable dynamic system. An assumptionof predicting the thickness of a steel plate using these tension formulae is also put forward.

An improved mathematical model for the continuous vacuum drying of highly viscous and heatsensitive foodstuffs was proposed, The process of continuous vacuum drying was presented as a moving boundary problem of moisture evaporation in cylindrical coordinates. Boundary condition of the first kind for the known functional dependence of the drying body surface temperature on time was considered. Finally, the appropriate system of differential equations was solved numerically and the values of drying rate, integral moisture content of the material, moving boundary position as well as temperature in any point of the material and at any moment time were obtained. This procedure was applied to continuous vacuum drying of foods such as natural cheese and fresh meat paste.

Confining continuous manipulations of accelerator beamline optics
Amstutz, Philipp; Bödewadt, Jörn; Lechner, Christoph; Plath, Tim; Vogt, Mathias
2016-01-01
Altering the optics in one section of a linear accelerator beamline will in general cause an alteration of the optics in all downstream sections. In circular accelerators, changing the optical properties of any beamline element will have an impact on the optical functions throughout the whole machine. In many cases, however, it is desirable to change the optics in a certain beamline section without disturbing any other parts of the machine. Such a local optics manipulation can be achieved by adjusting a number of additional corrector magnets that restore the initial optics after the manipulated section. In that case, the effect of the manipulation is confined in the region between the manipulated and the correcting beamline elements. Introducing a manipulation continuously, while the machine is operating, therefore requires continuous correction functions to be applied to the correcting quadrupole magnets. In this paper we present an analytic approach to calculate such continuous correction functions for six ...
Continuity Adjustment for Control Charts for Attributes
Institute of Scientific and Technical Information of China (English)
L.K. Chan; T.K. Mak; B. Tao
2003-01-01
A unified approach is proposed for making a continuity adjustment on some control charts for attributes, e.g., np-chart and c-chart, through adding a uniform (0, 1) random observation to the conventional sample statistic (e.g., npi and ci). The adjusted sample statistic then has a continuous distribution. Consequently, given any Type I risk α (the probability that the sample statistic is on or beyond the control limits),control charts achieving the exact value of α can be readily constructed. Guidelines are given for when to use the continuity adjustment control chart, the conventional Shewhart control chart (with ±3 standard deviations control limits), and the control chart based on the exact distribution of the sample statistic before adjustment.
Continuous Observations and the Wave Function Collapse
Marchewka, A
2011-01-01
We propose to modify the collapse axiom of quantum measurement theory by replacing the instantaneous with a continuous collapse of the wave function in finite time $\\tau$. We apply it to coordinate measurement of a free quantum particle that is initially confined to a domain $D\\subset\\rR^d$ and is observed continuously by illuminating $\\rR^d-D$. The continuous collapse axiom (CCA) defines the post-measurement wave function (PMWF)in $D$ after a negative measurement as the solution of Schr\\"odinger's equation at time $\\tau$ with instantaneously collapsed initial condition and homogeneous Dirichlet condition on the boundary of $D$. The CCA applies to all cases that exhibit the Zeno effect. It rids quantum mechanics of the unphysical artifacts caused by instantaneous collapse and introduces no new artifacts.
Experiments with Externally Prestressed Continuous Composite Girders

Full Text Available Steel-concrete composite girders have attractive potentials when applied in bridge construction. The serviceability performance of continuous composite girders is becoming more and more a deterministic parameter in the design of this type of structures. An effective method for improving this performance is to apply prestressing to control or completely eliminate concrete deck cracking caused by static and time dependent actions. Little literature has been found addressing the experimental analysis of continuous girders prestressed by means of external deviated tendons. The current research aims to investigate the behavior of a double-span steel composite beam externally prestressed by means of continuous tendons in terms of cracking characteristics, load deflection response, and load carrying capacity. The efficiency of prestressing is evaluated by comparing the results to those of a non-prestressed beam with similar cross sections and spans.

Full Text Available The accreditation process of a nursing program requires self-assessment, peer evaluation, and identifying areas of improvement. In 2008, the Commission on Collegiate Nursing Education (CCNE began offering a 10-year accreditation with a Continuous Improvement Progress Report (CIPR at the fifth year. This article focuses on an in-depth analysis of a system in which the school of nursing utilized an ad hoc committee to complete the CIPR. Reports generated by the ad hoc committee concluded that need for improvement was warranted related to policy review. An action plan for continuous compliance generated implementation of policy software and the creation of an academic support specialist position. An ad hoc committee completed the CIPR rather than paying faculty overload hours; policy was an exemplar. Faculty development, team performance, and accountability resulted in a plan for continual compliance that can be adopted in other nursing schools to meet CCNE accreditation.
Applications of a fast, continuous wavelet transform
Energy Technology Data Exchange (ETDEWEB)
Dress, W.B.
1997-02-01
A fast, continuous, wavelet transform, based on Shannon`s sampling theorem in frequency space, has been developed for use with continuous mother wavelets and sampled data sets. The method differs from the usual discrete-wavelet approach and the continuous-wavelet transform in that, here, the wavelet is sampled in the frequency domain. Since Shannon`s sampling theorem lets us view the Fourier transform of the data set as a continuous function in frequency space, the continuous nature of the functions is kept up to the point of sampling the scale-translation lattice, so the scale-translation grid used to represent the wavelet transform is independent of the time- domain sampling of the signal under analysis. Computational cost and nonorthogonality aside, the inherent flexibility and shift invariance of the frequency-space wavelets has advantages. The method has been applied to forensic audio reconstruction speaker recognition/identification, and the detection of micromotions of heavy vehicles associated with ballistocardiac impulses originating from occupants` heart beats. Audio reconstruction is aided by selection of desired regions in the 2-D representation of the magnitude of the transformed signal. The inverse transform is applied to ridges and selected regions to reconstruct areas of interest, unencumbered by noise interference lying outside these regions. To separate micromotions imparted to a mass-spring system (e.g., a vehicle) by an occupants beating heart from gross mechanical motions due to wind and traffic vibrations, a continuous frequency-space wavelet, modeled on the frequency content of a canonical ballistocardiogram, was used to analyze time series taken from geophone measurements of vehicle micromotions. By using a family of mother wavelets, such as a set of Gaussian derivatives of various orders, features such as the glottal closing rate and word and phrase segmentation may be extracted from voice data.

Full Text Available A summary of the relationship between the Langevin equation, Fokker-Planck-Kolmogorov forward equation (FPKfe and the Feynman path integral descriptions of stochastic processes relevant for the solution of the continuous-discrete filtering problem is provided in this paper. The practical utility of the path integral formula is demonstrated via some nontrivial examples. Specifically, it is shown that the simplest approximation of the path integral formula for the fundamental solution of the FPKfe can be applied to solve nonlinear continuous-discrete filtering problems quite accurately. The Dirac-Feynman path integral filtering algorithm is quite simple, and is suitable for real-time implementation.
Configurational space continuity and free energy calculations
Tian, Pu
2016-01-01
Free energy is arguably the most importance function(al) for understanding of molecular systems. A number of rigorous and approximate free energy calculation/estimation methods have been developed over many decades. One important issue, the continuity of an interested macrostate (or path) in configurational space, has not been well articulated, however. As a matter of fact, some important special cases have been intensively discussed. In this perspective, I discuss the relevance of configurational space continuity in development of more efficient and reliable next generation free energy methodologies.
Limitations of Continuous Glucose Monitor Usage.
Anhalt, Henry
2016-03-01
Much progress has been made in diabetes treatments since the first dose of insulin was administered in 1921. However, a truly transformational moment in diabetes care occurred when urine testing gave way to capillary blood home glucose monitoring. As improvements were made to these devices, continuous glucose monitoring (CGM) was introduced. The advantages of experiential learnings gleaned from seeing continuous real-time data have been borne out in numerous peer-reviewed journals. Limitations to use of CGM include patient's level of numeracy and literacy, development of alarm fatigue, interfering substances leading to erroneous readings, high rates of discontinuation, and poor reimbursement.
Hybrid Discrete-Continuous Markov Decision Processes
Feng, Zhengzhu; Dearden, Richard; Meuleau, Nicholas; Washington, Rich
2003-01-01
This paper proposes a Markov decision process (MDP) model that features both discrete and continuous state variables. We extend previous work by Boyan and Littman on the mono-dimensional time-dependent MDP to multiple dimensions. We present the principle of lazy discretization, and piecewise constant and linear approximations of the model. Having to deal with several continuous dimensions raises several new problems that require new solutions. In the (piecewise) linear case, we use techniques from partially- observable MDPs (POMDPS) to represent value functions as sets of linear functions attached to different partitions of the state space.

Full Text Available This paper will aim to presents the applications of a continuous-time parameter estimation method for estimating structural parameters of a real bridge structure. For the purpose of illustrating this method two case studies of a bridge pile located in a highly seismic risk area are considered, for which the structural parameters for the mass, damping and stiffness are estimated. The estimation process is followed by the validation of the analytical results and comparison with them to the measurement data. Further benefits and applications for the continuous-time parameter estimation method in civil engineering are presented in the final part of this paper.

This review highlights the state of the art in the field of continuous flow nitration with miniaturized devices. Although nitration has been one of the oldest and most important unit reactions, the advent of miniaturized devices has paved the way for new opportunities to reconsider the conventional approach for exothermic and selectivity sensitive nitration reactions. Four different approaches to flow nitration with microreactors are presented herein and discussed in view of their advantages, limitations and applicability of the information towards scale-up. Selected recent patents that disclose scale-up methodologies for continuous flow nitration are also briefly reviewed.

Full Text Available This paper discusses the concept of continuous improvement (CI by looking beyond what traditionally highlighted in literature concerning continuous improvement or Total Quality Management (TQM. The primary argument put forwarded in the discussion is that despite the undeniable positive results from CI practices, the way these activities are implemented, however, will lead to most programs becoming self-limiting. It needs to be asserted here that this paper is not intended to despise CI, rather, its purpose is limited only to provide a balance on the prevailing positive views toward CI.

Apparatus for fabricating continuous lengths of superconductor
Kroeger, Donald M.; List, III, Frederick A.
2002-01-01
A process and apparatus for manufacturing a superconductor. The process is accomplished by depositing a superconductor precursor powder on a continuous length of a first substrate ribbon, overlaying a continuous length of a second substrate ribbon on said first substrate ribbon, and applying sufficient pressure to form a bound layered superconductor comprising a layer of said superconducting precursor powder between said first substrate ribbon and said second substrates ribbon. The layered superconductor is then heat treated to establish the superconducting phase of said superconductor precursor powder.
Continuous flow nitration in miniaturized devices
Directory of Open Access Journals (Sweden)
Amol A. Kulkarni
2014-02-01
Full Text Available This review highlights the state of the art in the field of continuous flow nitration with miniaturized devices. Although nitration has been one of the oldest and most important unit reactions, the advent of miniaturized devices has paved the way for new opportunities to reconsider the conventional approach for exothermic and selectivity sensitive nitration reactions. Four different approaches to flow nitration with microreactors are presented herein and discussed in view of their advantages, limitations and applicability of the information towards scale-up. Selected recent patents that disclose scale-up methodologies for continuous flow nitration are also briefly reviewed.
THE CONTINUITY OF OPERATORS IN MATHEMATICAL MORPHOLOGY
Institute of Scientific and Technical Information of China (English)
高智民; 杨忠强
2002-01-01
In pattern analysis and image management, the information of an objective image can be recovered from a sequence approximate images. In mathematical form of expression it is needed to consider some types of continuity. Many researchers defined the limit and the upper limit of a sequence and, using the concepts, characterized continuity in the space consisted of images. In the present paper, the authors give firstly some examples to show that there are some theoretical shortcomings in those results, then give some corresponding correct results.
Optimal Nesting for Continuous Shape Stamping Processes
Institute of Scientific and Technical Information of China (English)
无
2000-01-01
This paper discusses the optimal nesting problem for minimizing the scrap in continuous shape stamping processes. The shape sliding technique is used to propose a new approach, OVERLAP-and-ESCAPE, to solve the problem of continuously nesting shapes onto a metal coil of fixed or selectable width. The approach is used to construct the objective function of the mathematical model of the problem using the Simulated Annealing Algorithm to determine the globally minimal configurations for the nesting problems. Some representative cases are studied and the results are encouraging. An automatic nesting software package for manufacturing bicycle chain link blanks is also described.
[Continuous ambulatory peritoneal dialysis: the perfect dialysis?].
Marichal, J F
1990-06-01
Among the dialysis method, Continuous Ambulatory Peritoneal Dialysis (CAPD) is considered as simple, efficient, economical and giving autonomy to the patient. After more than ten year using Continuous Ambulatory Peritoneal Dialysis, results are evaluated. The method remains simple, but the obvious simplicity demands a strict medical control. It is efficient, but the hope in anemia and osteodystrophy correction is not confirmed. It offers more freedom but with a lot of restraints: the dietary restriction must be followed and there is only relative moving autonomia. It is economical, but the costs with the use of disconnectable systems which reduce morbidity, bring it near to the home hemodialysis.
Discrete, Continuous, and Hybrid Petri Nets
David, Rene
2010-01-01
Petri Nets were introduced and still successfully used to analyze and model discrete event systems especially in engineering and computer sciences such as in automatic control. Recently this discrete Petri Nets formalism was successfully extended to continuous and hybrid systems. This monograph presents a well written and clearly organized introduction in the standard methods of Petri Nets with the aim to reach an accurate understanding of continuous and hybrid Petri Nets, while preserving the consistency of basic concepts throughout the book. The book is a monograph as well as a didactic tool
A Continuation Method for Weakly Kannan Maps
Directory of Open Access Journals (Sweden)
Ariza-Ruiz David
2010-01-01
Full Text Available The first continuation method for contractive maps in the setting of a metric space was given by Granas. Later, Frigon extended Granas theorem to the class of weakly contractive maps, and recently Agarwal and O'Regan have given the corresponding result for a certain type of quasicontractions which includes maps of Kannan type. In this note we introduce the concept of weakly Kannan maps and give a fixed point theorem, and then a continuation method, for this class of maps.

According to the modulation signal applied on laser diodes, wavelength modulation spectroscopy (WMS) can be divided into continuous wave (CW) WMS and quasi-continuous wave (QCW) WMS. In order to deeply compare CW-WMS and QCW-WMS, we used a specific software-realized lock-in amplifier for continuous and quasi-continuous modulation signal demodulation. The invalid signal in quasi-continuous modulation spectrum was filtered off, and then the effective detection signal was demodulated to obtain the second harmonic signal (WMS-2f). It was compared with the 2f signal demodulated continuous laser modulation spectrum with software. The results show that while the same system parameters are set, the signal-to-noise of the quasi-continuous modulation spectrum is 5% higher than the continuous modulation spectrum with software demodulation measurements, and the detection limit is 11.3% lower. And without the invalid signal in quasi-continuous modulation spectrum, the standard WMS-2f signal can be demodulated, which has potential to be used for the investigation of gas absorption profile. This work has provided accurate reference for selections of the laser modulation spectroscopy.

Layerless fabrication with continuous liquid interface production.
Janusziewicz, Rima; Tumbleston, John R; Quintanilla, Adam L; Mecham, Sue J; DeSimone, Joseph M
2016-10-18
Despite the increasing popularity of 3D printing, also known as additive manufacturing (AM), the technique has not developed beyond the realm of rapid prototyping. This confinement of the field can be attributed to the inherent flaws of layer-by-layer printing and, in particular, anisotropic mechanical properties that depend on print direction, visible by the staircasing surface finish effect. Continuous liquid interface production (CLIP) is an alternative approach to AM that capitalizes on the fundamental principle of oxygen-inhibited photopolymerization to generate a continual liquid interface of uncured resin between the growing part and the exposure window. This interface eliminates the necessity of an iterative layer-by-layer process, allowing for continuous production. Herein we report the advantages of continuous production, specifically the fabrication of layerless parts. These advantages enable the fabrication of large overhangs without the use of supports, reduction of the staircasing effect without compromising fabrication time, and isotropic mechanical properties. Combined, these advantages result in multiple indicators of layerless and monolithic fabrication using CLIP technology.

Quantum teleportation criteria for continuous variables
Grangier, P; Grangier, Philippe; Grosshans, Frederic
2000-01-01
We discuss the criteria presently used for evaluating the efficiency of quantum teleportation schemes for continuous variables. It is argued that the fidelity criterion used so far has some severe drawbacks, and that a fidelity value larger than 2/3 is actually required for successful quantum teleportation. This value has never been reached experimentally so far.

2014-06-01
Using the framework of ITIL best practises, the service managers within CERN-IT have engaged into a continuous improvement process, mainly focusing on service operation. This implies an explicit effort to understand and improve all service management aspects in order to increase efficiency and effectiveness. We will present the requirements, how they were addressed and share our experiences. We will describe how we measure, report and use the data to continually improve both the processes and the services being provided. The focus is not the tool or the process, but the results of the continuous improvement effort from a large team of IT experts providing services to thousands of users, supported by the tool and its local team. This is not an initiative to address user concerns in the way the services are managed but rather an on-going working habit of continually reviewing, analysing and improving the service management processes and the services themselves, having in mind the currently agreed service levels and whose results also improve the experience of the users about the current services.

Continuous respirable mine dust monitor development
Energy Technology Data Exchange (ETDEWEB)
Cantrell, B.K.; Williams, K.L.; Stein, S.W. [and others
1996-12-31
In June 1992, the Mine Safety and Health Administration (MSHA) published the Report of the Coal Mine Respirable Dust Task Group, Review of the Program to Control Respirable Coal Mine Dust in the United States. As one of its recommendations, the report called for the accelerated development of two mine dust monitors: (1) a fixed-site monitor capable of providing continuous information on dust levels to the miner, mine operator, and to MSHA, if necessary, and (2) a personal sampling device capable of providing both a short-term personal exposure measurement as well as a full-shift measurement. In response to this recommendation, the U.S. Bureau of Mines initiated the development of a fixed-site machine-mounted continuous respirable dust monitor. The technology chosen for monitor development is the Rupprecht and Patashnick Co., Inc. tapered element oscillating microbalance. Laboratory and in-mine tests have indicated that, with modification, this sensor can meet the humidity and vibration requirements for underground coal mine use. The U.S. Department of Energy Pittsburgh Research Center (DOE-PRC) is continuing that effort by developing prototypes of a continuous dust monitor based on this technology. These prototypes are being evaluated in underground coal mines as they become available. This effort, conducted as a joint venture with MSHA, is nearing completion with every promise of success.

Despite the increasing popularity of 3D printing, also known as additive manufacturing (AM), the technique has not developed beyond the realm of rapid prototyping. This confinement of the field can be attributed to the inherent flaws of layer-by-layer printing and, in particular, anisotropic mechanical properties that depend on print direction, visible by the staircasing surface finish effect. Continuous liquid interface production (CLIP) is an alternative approach to AM that capitalizes on the fundamental principle of oxygen-inhibited photopolymerization to generate a continual liquid interface of uncured resin between the growing part and the exposure window. This interface eliminates the necessity of an iterative layer-by-layer process, allowing for continuous production. Herein we report the advantages of continuous production, specifically the fabrication of layerless parts. These advantages enable the fabrication of large overhangs without the use of supports, reduction of the staircasing effect without compromising fabrication time, and isotropic mechanical properties. Combined, these advantages result in multiple indicators of layerless and monolithic fabrication using CLIP technology. PMID:27671641

Reversible phenotypic plasticity with continuous adaptation.
Pfab, Ferdinand; Gabriel, Wilfried; Utz, Margarete
2016-01-01
We introduce a novel model for continuous reversible phenotypic plasticity. The model includes a one-dimensional environmental gradient, and we describe performance of an organism as a function of the environmental state by a Gaussian tolerance curve. Organisms are assumed to adapt their tolerance curve after a change of the environmental state. We present a general framework for calculating the genotype fitness if such adaptations happen in a continuous manner and apply the model to a periodically changing environment. Significant differences of our model with previous models for plasticity are the continuity of adaptation, the presence of intermediate phenotypes, that the duration of transformations depends on their extent, fewer restrictions on the distribution of the environment, and a higher robustness with respect to assumptions about environmental fluctuations. Further, we show that continuous reversible plasticity is beneficial mainly when environmental changes occur slow enough so that fully developed phenotypes can be exhibited. Finally we discuss how the model framework can be generalized to a wide variety of biological scenarios from areas that include population dynamics, evolution of environmental tolerance and physiology.

Continuous cold therapy in total knee arthroplasty.
Leutz, D W; Harris, H
1995-01-01
This article describes a retrospective study that assessed 52 consecutive patients who underwent total knee arthroplasty (TKA) between January 1, 1992 and September 15, 1992. Thirty-three patients underwent TKA and received cold therapy pads placed over a thin dressing in the operating room. Nineteen patients underwent TKA using an identical operative and postoperative procedure, but did not receive continuous cold therapy. Continuous cold therapy consisted of two sterile plastic pads connnected by rubber hoses containing cool water from an electric main unit that maintained a constant temperature of 42 degrees F for the immediate postoperative period. Cold therapy pads were used an average of 3 days and removed with the first dressing change. Patients who had continuous cold therapy averaged a 200 cc decrease in postoperative blood loss. There was no significant difference in the amount of narcotic use, transfusion requirements, or hospital stay between the two groups. Postoperative swelling and range of motion were not consistently recorded. Twenty-eight other variables also examined not significant. Based on these results, we cannot recommend continuous cold therapy or justify the extra expense for all patients who undergo TKA.

Diabetes mellitus is an independent risk factor for cardiovascular disease. To compare the efficacy of devices for continuous glucose monitoring and capillary glucose monitoring in hospitalized patients with acute coronary syndrome using the following parameters: time to achieve normoglycemia, period of time in normoglycemia, and episodes of hypoglycemia. We performed a pilot, non-randomized, unblinded clinical trial that included 16 patients with acute coronary artery syndrome, a capillary or venous blood glucose ≥ 140 mg/dl, and treatment with a continuous infusion of fast acting human insulin. These patients were randomized into 2 groups: a conventional group, in which capillary measurement and recording as well as insulin adjustment were made every 4h, and an intervention group, in which measurement and recording as well as insulin adjustment were made every hour with a subcutaneous continuous monitoring system. Student's t-test was applied for mean differences and the X(2) test for qualitative variables. We observed a statistically significant difference in the mean time for achieving normoglycemia, favoring the conventional group with a P = 0.02. Continuous monitoring systems are as useful as capillary monitoring for achieving normoglycemia. Copyright © 2012 Instituto Nacional de Cardiología Ignacio Chávez.

Full Text Available The study analyzes the importance of continuing education in the expectation of obtaining social changes through the construction and reconstruction of knowledge. The object of analysis is the Specialization Course in School Management, linked to the National School of Public Managers Basic Education / MEC / SEB, implemented by the Federal University of Western Para / UFOPA in 2011. The study was performed by means of literature analysis and field survey with questionnaires and focus groups with graduates of that course, having sustained analysis on three themes: Continuing education by the school manager EAD; management and improving learning outcomes and democratic management: problems and possibilities. It was found that continuing education for managers contributed to add knowledge to be applied in their daily practice. The subjects recognize the importance of continuing education to achieve social change from the perspective of building a school socially relevant and that the knowledge acquired in the course also led to improved learning outcomes of students in schools where they work, considered not only the perspective statistic, but mostly about the gains related to the understanding of the problems and the possibility of collaborative solution. The directors surveyed consider that they now know what democratic management is, but recognize that is still a challenge to its implementation in schools.

Disons pour conclure que, en tout état de cause, la façon de concevoir philosophiquement le conflit du continu et de l'espace que nous avons trouvée chez Hegel n'est pas homogène avec le style et les modalités de la pensée mathématique: 1) d'une part, le lien classique, le lien de référence entre continu et espace en mathématiques n'est pas que l'espace serait premier et privé de pensée, et le continu second, venant dissoudre l'espace en apportant la qualité, l'infini et la pensée, mais tout au contraire, il consiste en ce que l'espace est fondé sur l'abîme infinitaire du continu ; 2) d'autre part, l'éventuel divorce entre l'espace et le continu dans l'aire mathématique n'est pas celui d'une réflexivité purement conceptuelle du continu avec un positivisme géométrique, n'équivaut pas à une rupture disciplinaire ; il est plutôt le symptôme de la dérive d'une herméneutique à l'égard d'une autre, au sein d'un continent juridique commun définissant la discipline (la mathématique ensembliste), cette dérive pouvant, à la limite, induire une refonte de ce sol juridique, sans que jamais il soit question pour autant de nier l'unité des mathématiques, à comprendre ici comme l'unité ultime de responsabilité de la communauté mathématique à l'égard des trois questions Qu'est-ce que l'espace?”, “Qu'est-ce que le continu?” et “Qu'est-ce que l'infini?”.

Full Text Available The notions of continuity was generalized in the fuzzy setting by Chang (1968. Later on Azad (1981 introduced some weaker form of fuzzy continuity like fuzzy almost continuity, fuzzy semi-continuity and fuzzy weak continuity. These are natural generalization of the corresponding weaker forms of continuity in topological spaces. Recently Arya and Singal (2001a and b introduce another weaker form of fuzzy continuity, namely fuzzy subweakly continuity as a natural generalization of subweak continuity introduced by Rose (1984. In this paper we introduce fuzzy weak continuity in mixed fuzzy topological space.

Workflow continuity--moving beyond business continuity in a multisite 24-7 healthcare organization.
Kolowitz, Brian J; Lauro, Gonzalo Romero; Barkey, Charles; Black, Harry; Light, Karen; Deible, Christopher
2012-12-01
As hospitals move towards providing in-house 24 × 7 services, there is an increasing need for information systems to be available around the clock. This study investigates one organization's need for a workflow continuity solution that provides around the clock availability for information systems that do not provide highly available services. The organization investigated is a large multifacility healthcare organization that consists of 20 hospitals and more than 30 imaging centers. A case analysis approach was used to investigate the organization's efforts. The results show an overall reduction in downtimes where radiologists could not continue their normal workflow on the integrated Picture Archiving and Communications System (PACS) solution by 94 % from 2008 to 2011. The impact of unplanned downtimes was reduced by 72 % while the impact of planned downtimes was reduced by 99.66 % over the same period. Additionally more than 98 h of radiologist impact due to a PACS upgrade in 2008 was entirely eliminated in 2011 utilizing the system created by the workflow continuity approach. Workflow continuity differs from high availability and business continuity in its design process and available services. Workflow continuity only ensures that critical workflows are available when the production system is unavailable due to scheduled or unscheduled downtimes. Workflow continuity works in conjunction with business continuity and highly available system designs. The results of this investigation revealed that this approach can add significant value to organizations because impact on users is minimized if not eliminated entirely.

Excursions in fluvial (dis)continuity
Grant, Gordon E.; O'Connor, James E.; Safran, Elizabeth
2017-01-01
Lurking below the twin concepts of connectivity and disconnectivity are their first, and in some ways, richer cousins: continuity and discontinuity. In this paper we explore how continuity and discontinuity represent fundamental and complementary perspectives in fluvial geomorphology, and how these perspectives inform and underlie our conceptions of connectivity in landscapes and rivers. We examine the historical roots of continuum and discontinuum thinking, and how much of our understanding of geomorphology rests on contrasting views of continuity and discontinuity. By continuum thinking we refer to a conception of geomorphic processes as well as geomorphic features that are expressed along continuous gradients without abrupt changes, transitions, or thresholds. Balance of forces, graded streams, and hydraulic geometry are all examples of this perspective. The continuum view has played a prominent role in diverse disciplinary fields, including ecology, paleontology, and evolutionary biology, in large part because it allows us to treat complex phenomena as orderly progressions and invoke or assume equilibrium processes that introduce order and prediction into our sciences.In contrast the discontinuous view is a distinct though complementary conceptual framework that incorporates non-uniform, non-progressive, and non-equilibrium thinking into understanding geomorphic processes and landscapes. We distinguish and discuss examples of three different ways in which discontinuous thinking can be expressed: 1) discontinuous spatial arrangements or singular events; 2) specific process domains generally associated with thresholds, either intrinsic or extrinsic; and 3) physical dynamics or changes in state, again often threshold-linked. In moving beyond the continuous perspective, a fertile set of ideas comes into focus: thresholds, non-equilibrium states, heterogeneity, catastrophe. The range of phenomena that is thereby opened up to scientific exploration similarly expands
Applications of a fast continuous wavelet transform
Dress, William B.
1997-04-01
A fast, continuous, wavelet transform, justified by appealing to Shannon's sampling theorem in frequency space, has been developed for use with continuous mother wavelets and sampled data sets. The method differs from the usual discrete-wavelet approach and from the standard treatment of the continuous-wavelet transform in that, here, the wavelet is sampled in the frequency domain. Since Shannon's sampling theorem lets us view the Fourier transform of the data set as representing the continuous function in frequency space, the continuous nature of the functions is kept up to the point of sampling the scale-translation lattice, so the scale-translation grid used to represent the wavelet transform is independent of the time-domain sampling of the signal under analysis. Although more computationally costly and not represented by an orthogonal basis, the inherent flexibility and shift invariance of the frequency-space wavelets are advantageous for certain applications. The method has been applied to forensic audio reconstruction, speaker recognition/identification, and the detection of micromotions of heavy vehicles associated with ballistocardiac impulses originating from occupants' heart beats. Audio reconstruction is aided by selection of desired regions in the 2D representation of the magnitude of the transformed signals. The inverse transform is applied to ridges and selected regions to reconstruct areas of interest, unencumbered by noise interference lying outside these regions. To separate micromotions imparted to a mass- spring system by an occupant's beating heart from gross mechanical motions due to wind and traffic vibrations, a continuous frequency-space wavelet, modeled on the frequency content of a canonical ballistocardiogram, was used to analyze time series taken from geophone measurements of vehicle micromotions. By using a family of mother wavelets, such as a set of Gaussian derivatives of various orders, different features may be extracted from voice
White paper on continuous bioprocessing. May 20-21, 2014 Continuous Manufacturing Symposium.
Konstantinov, Konstantin B; Cooney, Charles L
2015-03-01
There is a growing interest in realizing the benefits of continuous processing in biologics manufacturing, which is reflected by the significant number of industrial and academic researchers who are actively involved in the development of continuous bioprocessing systems. These efforts are further encouraged by guidance expressed in recent US FDA conference presentations. The advantages of continuous manufacturing include sustained operation with consistent product quality, reduced equipment size, high-volumetric productivity, streamlined process flow, low-process cycle times, and reduced capital and operating cost. This technology, however, poses challenges, which need to be addressed before routine implementation is considered. This paper, which is based on the available literature and input from a large number of reviewers, is intended to provide a consensus of the opportunities, technical needs, and strategic directions for continuous bioprocessing. The discussion is supported by several examples illustrating various architectures of continuous bioprocessing systems.
a Continuous-Time Positive Linear System
Directory of Open Access Journals (Sweden)
Kyungsup Kim
2013-01-01
Full Text Available This paper discusses a computational method to construct positive realizations with sparse matrices for continuous-time positive linear systems with multiple complex poles. To construct a positive realization of a continuous-time system, we use a Markov sequence similar to the impulse response sequence that is used in the discrete-time case. The existence of the proposed positive realization can be analyzed with the concept of a polyhedral convex cone. We provide a constructive algorithm to compute positive realizations with sparse matrices of some positive systems under certain conditions. A sufficient condition for the existence of a positive realization, under which the proposed constructive algorithm works well, is analyzed.
Dynamics of neural networks with continuous attractors
Fung, C. C. Alan; Wong, K. Y. Michael; Wu, Si
2008-10-01
We investigate the dynamics of continuous attractor neural networks (CANNs). Due to the translational invariance of their neuronal interactions, CANNs can hold a continuous family of stationary states. We systematically explore how their neutral stability facilitates the tracking performance of a CANN, which is believed to have wide applications in brain functions. We develop a perturbative approach that utilizes the dominant movement of the network stationary states in the state space. We quantify the distortions of the bump shape during tracking, and study their effects on the tracking performance. Results are obtained on the maximum speed for a moving stimulus to be trackable, and the reaction time to catch up an abrupt change in stimulus.

A general mathematical model and boundary condition applicable to momentum and heat transfer in the semisolid continuous casting(SCC) process was established. Using the model, the numerical simulation of the momentum and heat transfer of molten metal was carried out in the SCC system. The obtained results fit well with the measured ones. Moreover, using the numerical simulating software, the effect of various factors on breakout and breakage was explored. The obtained results show that heat flow density of copper mold and the withdrawal beginning time are two major influencing factors. The larger the heat flow density of copper mold, or the shorter the withdrawal beginning time, the more stable the semisolid continuous casting process.
Continuous ethanol production under acidic conditions
Energy Technology Data Exchange (ETDEWEB)
1983-09-06
Gelatinized starch is treated with saccharifying enzymes and immobilized EtOH-producing microorganisms (e.g., Saccharomyces, Candida, Zymomonas) at pH less than or equal to 3.4 to produce EtOH continuously. At this pH, no contamination occurs. Thus, a 25% slurry of cassava powder was heated at 120/sup 0/ for 20 min and mixed with ..cap alpha..-amylase 0.6 and CaCl/sub 2/ 2 g/l. The mixture was stirred at 90/sup 0/ for 30 min, cooled to room temperature, filtered, and the filtrate mixed with 1 g (NH/sub 4/)/sub 2/SO/sub 4/ and adjusted to pH 2.8. A mixture of wine and bakers' yeast (500 g) immobilized on alginate was continuously contacted with the saccharified starch solution to yield 77-90 g EtOH/l.

Rare Earth Additions in Continuously Cast Steel
Wilson, William G.; Heaslip, L. J.; Sommerville, I. D.
1985-09-01
Rare earth (lanthanide metals) addiiions to continuously cast steel are particularly advantageous because of their ability to refine as-cast structures, reduce segregation and increase hot ductility at temperatures just below that of solidification. The complete shape control of sulfides in steels containing Rare Earth Metals (REM), whether continuously cast or ingot cast, is primarily responsible for improvements in ductility related mechanical properties, weldability, fatigue resistance and resistance to hydrogen damage. Complete sulfide shape control can be obtained with REM additions at sulfur levels as high as.020%. The greatest improvements, however, are obtained with REM additions to low sulfur steels. However, to achieve full operational advantages afforded by REM, nozzle blockage problems must be circumvented. Water model studies indicate a possible solution.
Continuous Glucose Monitoring Systems: A Review

2013-10-01
Full Text Available There have been continuous advances in the field of glucose monitoring during the last four decades, which have led to the development of highly evolved blood glucose meters, non-invasive glucose monitoring (NGM devices and continuous glucose monitoring systems (CGMS. Glucose monitoring is an integral part of diabetes management, and the maintenance of physiological blood glucose concentration is the only way for a diabetic to avoid life-threatening diabetic complications. CGMS have led to tremendous improvements in diabetic management, as shown by the significant lowering of glycated hemoglobin (HbA1c in adults with type I diabetes. Most of the CGMS have been minimally-invasive, although the more recent ones are based on NGM techniques. This manuscript reviews the advances in CGMS for diabetes management along with the future prospects and the challenges involved.

The sensor is capable of making continuous, real time quantitative measurements of desired elements, such as the heavy metals lead and mercury.
Continuous steam hydrolysis of tulip poplar
Energy Technology Data Exchange (ETDEWEB)
Fieber, C.; Colcord, A.R.; Faass, S.; Muzzy, J.D.; Roberts, R.S.
1982-08-01
To produce ethanol from hardwood it is desirable to fractionate the hardwood in order to produce a relatively pure cellulosic pulp for dilute acid hydrolysis. An experimental investigation of continuous steam hydrolysis of tulip poplar wood chips indicates that over 90% of the lignin present can be extracted by 0.1N sodium hydroxide, resulting in a cellulose pulp containing over 90% hexosan. The study was performed using a Stake Technology, Ltd., continuous digester rated at one oven dry ton per hour of wood chips. The yields of hexosans, hexoses, xylan, xylose, lignin, furfural, acetic acid and methanol were determined as a function of residence time and steam pressure in the digester. The information provides a basis for establishing a material and energy balance for a hardwood to ethanol plant.
CONSTRUCTION OF CONTINUOUS TIME MARKOVIAN ARRIVAL PROCESSES

2010-01-01
Markovian arrival processes were introduced by Neuts in 1979(Neuts 1979)and have been used extensively in the stochastic modeling of queueing,inventory,reliability,risk,and telecommunications systems.In this paper,we introduce a constructive approach to define continuous time Markovian arrival processes.The construction is based on Poisson processes,and is simple and intuitive.Such a construction makes it easy to interpret the parameters of Markovian arrival processes.The construction also makes it possible to establish rigorously basic equations,such as Kolmogorov differential equations,for Markovian arrival processes,using only elementary properties of exponential distributions and Poisson processes.In addition,the approach can be used to construct continuous time Markov chains with a finite number of states
The ultimatum game: Discrete vs. continuous offers
Dishon-Berkovits, Miriam; Berkovits, Richard
2014-09-01
In many experimental setups in social-sciences, psychology and economy the subjects are requested to accept or dispense monetary compensation which is usually given in discrete units. Using computer and mathematical modeling we show that in the framework of studying the dynamics of acceptance of proposals in the ultimatum game, the long time dynamics of acceptance of offers in the game are completely different for discrete vs. continuous offers. For discrete values the dynamics follow an exponential behavior. However, for continuous offers the dynamics are described by a power-law. This is shown using an agent based computer simulation as well as by utilizing an analytical solution of a mean-field equation describing the model. These findings have implications to the design and interpretation of socio-economical experiments beyond the ultimatum game.
Cutting as a continuous business process
Directory of Open Access Journals (Sweden)
Miro Gradišar
2009-11-01
Full Text Available A review of state-of-the-art methods for cutting stock problem optimisation shows that the current methods lead to near-optimum results for the instantaneous optimisation of trim loss. Further optimisation of this activity would not bring a considerable improvement. Therefore, the paper treats cutting stock as a continuous business process and not as an isolated activity. An exact method for a general one-dimensional cutting stock problem is presented and tested. The method is mainly suitable for smaller orders. It is then applied to continuous cutting and used to develop a method for assessing cutting costs in consecutive time periods. The modified method finds a good solution over the whole time-span, rather than just local optima.
Continuation of Sets of Constrained Orbit Segments
DEFF Research Database (Denmark)
Schilder, Frank; Brøns, Morten; Chamoun, George Chaouki;
Sets of constrained orbit segments of time continuous flows are collections of trajectories that represent a whole or parts of an invariant set. A non-trivial but simple example is a homoclinic orbit. A typical representation of this set consists of an equilibrium point of the flow and a trajectory...... that starts close and returns close to this fixed point within finite time. More complicated examples are hybrid periodic orbits of piecewise smooth systems or quasi-periodic invariant tori. Even though it is possible to define generalised two-point boundary value problems for computing sets of constrained...... orbit segments, this is very disadvantageous in practice. In this talk we will present an algorithm that allows the efficient continuation of sets of constrained orbit segments together with the solution of the full variational problem....
Continuation of point clouds via persistence diagrams
Gameiro, Marcio; Hiraoka, Yasuaki; Obayashi, Ippei
2016-11-01
In this paper, we present a mathematical and algorithmic framework for the continuation of point clouds by persistence diagrams. A key property used in the method is that the persistence map, which assigns a persistence diagram to a point cloud, is differentiable. This allows us to apply the Newton-Raphson continuation method in this setting. Given an original point cloud P, its persistence diagram D, and a target persistence diagram D‧, we gradually move from D to D‧, by successively computing intermediate point clouds until we finally find a point cloud P‧ having D‧ as its persistence diagram. Our method can be applied to a wide variety of situations in topological data analysis where it is necessary to solve an inverse problem, from persistence diagrams to point cloud data.
Developing a Forensic Continuous Audit Model
Directory of Open Access Journals (Sweden)
Grover S. Kearns
2011-06-01
Full Text Available Despite increased attention to internal controls and risk assessment, traditional audit approaches do not seem to be highly effective in uncovering the majority of frauds. Less than 20 percent of all occupational frauds are uncovered by auditors. Forensic accounting has recognized the need for automated approaches to fraud analysis yet research has not examined the benefits of forensic continuous auditing as a method to detect and deter corporate fraud. The purpose of this paper is to show how such an approach is possible. A model is presented that supports the acceptance of forensic continuous auditing by auditors and management as an effective tool to support the audit function, meet managementâ€™s regulatory objectives, and to combat fraud. An approach to developing such a system is presented.
Continuous synthesis of silicon carbide whiskers
Choi, Heon-Jin; Lee, June-Gunn
1995-04-01
Experimental synthesis of SiC whiskers coupled with thermodynamic calculations revealed the preferred reaction routes for the efficient synthesis of SiC whiskers. This formed the basis for the design of a continuous reactor, which consists of a boat-train loaded with silica-carbon mixture and iron-coated graphite substrate above it in an alumina-tube reactor. High-quality SiC whiskers have been grown with diameters of 1-3 micron. The yield was about 30% based on the silicon input as SiO2 and output as SiC whiskers. This demonstrates the feasibility of continuous SiC whiskers production without the additional processes of purification and classification.
Learning to forget: continual prediction with LSTM.
Gers, F A; Schmidhuber, J; Cummins, F
2000-10-01
Long short-term memory (LSTM; Hochreiter & Schmidhuber, 1997) can solve numerous tasks not solvable by previous learning algorithms for recurrent neural networks (RNNs). We identify a weakness of LSTM networks processing continual input streams that are not a priori segmented into subsequences with explicitly marked ends at which the network's internal state could be reset. Without resets, the state may grow indefinitely and eventually cause the network to break down. Our remedy is a novel, adaptive "forget gate" that enables an LSTM cell to learn to reset itself at appropriate times, thus releasing internal resources. We review illustrative benchmark problems on which standard LSTM outperforms other RNN algorithms. All algorithms (including LSTM) fail to solve continual versions of these problems. LSTM with forget gates, however, easily solves them, and in an elegant way.
[Changing aspects in continuing medical education].
Okisaka, Shigekuni
2007-02-01
Self-directed learning based on adult education theory and self-assessment are necessary for continuing medical education. Self-directed learning is the process whereby the individual takes the initiative in diagnosing his learning needs and setting his own individual learning goals, showing clearly the human and physical resources, putting an appropriate plan into practice, and evaluating the learning outcome. Because self-assessment is the evaluation of the process where the individual confirms his actual learning, portfolio assessment is utilized for this purpose. In the continuing medical education program of the Japanese Ophthalmological Society, it is vital that the appropriate credit and recognition program keep up with the changes in adult education theory. Therefore, portfolio assessment is introduced for self-assessment. The Ophthalmic Pathology Slide Seminar is a model of medical education based on self-directed learning.

Squeezing and Entanglement in Continuous Variable Systems
Institute of Scientific and Technical Information of China (English)
XIA Yun-Jie; GUO Guang-Can
2004-01-01
Based on total variance of a pair of Einstein-Podolsky-Rosen (EPR) type operators, the generalized EPR entangled states in continuous variable systems are defined. We show that such entangled states must correspond to two-mode squeezing states whether these states are Gaussian or not and whether they are pure or not. With help of the relation between the total variance and the entanglement, the degree of such entanglement is also defined. Through analysing some specific cases, we see that this method is very convenient and easy in practical applications. In addition, an entangled state with no squeezing is studied, which reveals that there certainly exists something unknown about entanglement in continuous variable systems.

2007-01-01
By applying the continuous finite element methods of ordinary differential equations, the linear element methods are proved having second-order pseudo-symplectic scheme and the quadratic element methods are proved having third-order pseudosymplectic scheme respectively for general Hamiltonian systems, and they both keep energy conservative. The finite element methods are proved to be symplectic as well as energy conservative for linear Hamiltonian systems. The numerical results are in agreement with theory.

2002-01-01
In this paper, we describe five investment streams (data storage infrastructure, knowledge management, data production control, data transport and security, and personnel skill mix) that need to be balanced against short-term operating demands in order to maximize the probability of long-term viability of a digital library. Because of the rapid pace of information technology change, a digital library cannot be a static institution. Rather, it has to become a flexible organization adapted to continuous evolution of its infrastructure.

Waiting time distribution for continuous stochastic systems.
Gernert, Robert; Emary, Clive; Klapp, Sabine H L
2014-12-01
The waiting time distribution (WTD) is a common tool for analyzing discrete stochastic processes in classical and quantum systems. However, there are many physical examples where the dynamics is continuous and only approximately discrete, or where it is favourable to discuss the dynamics on a discretized and a continuous level in parallel. An example is the hindered motion of particles through potential landscapes with barriers. In the present paper we propose a consistent generalization of the WTD from the discrete case to situations where the particles perform continuous barrier crossing characterized by a finite duration. To this end, we introduce a recipe to calculate the WTD from the Fokker-Planck (Smoluchowski) equation. In contrast to the closely related first passage time distribution (FPTD), which is frequently used to describe continuous processes, the WTD contains information about the direction of motion. As an application, we consider the paradigmatic example of an overdamped particle diffusing through a washboard potential. To verify the approach and to elucidate its numerical implications, we compare the WTD defined via the Smoluchowski equation with data from direct simulation of the underlying Langevin equation and find full consistency provided that the jumps in the Langevin approach are defined properly. Moreover, for sufficiently large energy barriers, the WTD defined via the Smoluchowski equation becomes consistent with that resulting from the analytical solution of a (two-state) master equation model for the short-time dynamics developed previously by us [Phys. Rev. E 86, 061135 (2012)]. Thus, our approach "interpolates" between these two types of stochastic motion. We illustrate our approach for both symmetric systems and systems under constant force.

Managing Parkinson's disease with continuous dopaminergic stimulation.
Wolters, Erik; Lees, Andrew J; Volkmann, Jens; van Laar, Teus; Hovestadt, Ad
2008-04-01
The pathophysiology of Parkinson's disease is marked by the loss of dopaminergic neurons, which leads to striatal dopaminergic deficiency. This causes resting tremor, hypokinesia, rigidity, bradykinesia, and loss of postural reflexes. Most current treatments for Parkinson's disease aim to restore striatal dopamine signaling by increasing the supply of dopamine with oral levodopa (L-dopa), stimulating dopamine receptors directly using dopamine agonists, or inhibiting the reuptake of endogenous dopamine. L-dopa is standard therapy for patients with Parkinson's disease. However, with continued treatment and disease progression, the response to oral dopaminergic drugs becomes unstable and motor fluctuations emerge, including off periods and dyskinesia. Direct duodenal-administered infusible L-dopa/carbidopa is effective for the management of refractory motor fluctuations in some patient populations. However, enteral infusions cannot mimic the function of the normal dopaminergic brain, and around-the-clock constant-rate administration carries the risk of causing refractory off periods associated with severe immobility and hyperpyrexia. Subthalamic nucleus (STN) deep brain stimulation (DBS) is also a promising treatment. DBS passes a high-frequency electrical current into the target area, mimicking the effect of lesioning the stimulated area. However, this treatment requires invasive surgery and is appropriate for a limited segment of the patient population. This supplement provides a rationale for the use of continuous dopaminergic receptor stimulation and offers guidelines on the individualization of treatment decisions, with special focus on continuous L-dopa infusion and STN DBS. Erik Wolters, MD, PhD, offers an introduction to the impact of continuous L-dopa infusion. Andrew J. Lees, MD, FRCP, provides an overview of the physiologic response to L-dopa and reviews clinical pharmacologic studies of intravenous and intraduodenal L-dopa. Jens Volkmann, MD, discusses

We demonstrate that the Byzantine Agreement Problem (BAP) in its weaker version with detectable broadcast, can be solved using continuous variables Gaussian states with Gaussian operations. The protocol uses genuine tripartite symmetric entanglement, but differs from protocols proposed for qutrits or qubits. Contrary to the quantum key distribution (QKD) which is possible with all Gaussian states, for the BAP entanglement is needed, but not all tripartite entangled symmetric states can be used to solve the problem.

Coherent communication with continuous quantum variables
Wilde, Mark M.; Krovi, Hari; Brun, Todd A.
2007-06-01
The coherent bit (cobit) channel is a resource intermediate between classical and quantum communication. It produces coherent versions of teleportation and superdense coding. We extend the cobit channel to continuous variables by providing a definition of the coherent nat (conat) channel. We construct several coherent protocols that use both a position-quadrature and a momentum-quadrature conat channel with finite squeezing. Finally, we show that the quality of squeezing diminishes through successive compositions of coherent teleportation and superdense coding.

Continuous magnetic reconnection at Earth's magnetopause.
Frey, H U; Phan, T D; Fuselier, S A; Mende, S B
2003-12-04
The most important process that allows solar-wind plasma to cross the magnetopause and enter Earth's magnetosphere is the merging between solar-wind and terrestrial magnetic fields of opposite sense-magnetic reconnection. It is at present not known whether reconnection can happen in a continuous fashion or whether it is always intermittent. Solar flares and magnetospheric substorms--two phenomena believed to be initiated by reconnection--are highly burst-like occurrences, raising the possibility that the reconnection process is intrinsically intermittent, storing and releasing magnetic energy in an explosive and uncontrolled manner. Here we show that reconnection at Earth's high-latitude magnetopause is driven directly by the solar wind, and can be continuous and even quasi-steady over an extended period of time. The dayside proton auroral spot in the ionosphere--the remote signature of high-latitude magnetopause reconnection--is present continuously for many hours. We infer that reconnection is not intrinsically intermittent; its steadiness depends on the way that the process is driven.

On this basis, we designed a survey administered to a group of 30 large companies, each of which is renowned leader in Argentina. Finally, we compared the development of continuous improvement process in companies with very effective results and with scarce results. Differences that emerged from this comparison enabled us to identify critical factors for achieving a successful improvement process. As there are no recent researches on continuous improvement programs in Argentina, this paper contributes to recognizing and systematizing what has been done, comparing it with theoretical framework and uncovering research gaps for future studies. However, further research must confirm these findings and move forward on the analysis of intangible factors, like: internal communications, climate, culture, self reflexion, consensus, etc.
Scalar-tensor gravity and conformal continuations
Bronnikov, K A
2002-01-01
Global properties of vacuum static, spherically symmetric configurations are studied in a general class of scalar-tensor theories (STT) of gravity in various dimensions. The conformal mapping between the Jordan and Einstein frames is used as a tool. Necessary and sufficient conditions are found for the existence of solutions admitting a conformal continuation (CC). The latter means that a singularity in the Einstein-frame manifold maps to a regular surface S_(trans) in the Jordan frame, and the solution is then continued beyond this surface. S_(trans) can be an ordinary regular sphere or a horizon. In the second case, S_(trans) proves to connect two epochs of a Kantowski-Sachs type cosmology. It is shown that, in an arbitrary STT, with arbitrary potential functions $U(\\phi)$, the list of possible types of causal structures of vacuum space-times is the same as in general relativity with a cosmological constant. This is true even for conformally continued solutions. It is found that when S_(trans) is an ordinar...
Modeling of continuous strip production by rheocasting
Matsumiya, T.; Flemings, M. C.
1981-03-01
A process was experimentally and mathematically modeled for continuous and direct production of metal strip from its molten state by the use of Rheocasting. The process comprises 1) continuous production of a Rheocast semisolid alloy, and 2) direct shaping of the semisolid into strip. Sn-15 pct Pb was used as the modeling alloy. Crack formation and surface quality of the strip produced depend on fraction solid and deformation force. Continuous, sound strip could be obtained with good surface quality when fraction solid was between 0.50 and 0.70 and deformation force did not exceed a given maximum. Sheet thickness depends on deformation force, fraction solid, rotor rate of Rheocaster and production line speed. At constant deformation force, sheet thickness increases as fraction solid increases, rotor rate decreases and line speed is reduced. Sheet thickness is larger in the center than in the edge, but the difference is reduced by applying edgers. Some segregation of lead toward the edges is observed, and the segregation increases as amount of deformation is increased. A mathematical model for heat flow, solidification and deformation was constructed. The model predicts the point of completion of solidification in the strip and sheet thickness as a function of deformation force and line speed. Calculations are in good agreement with experimental results.

Continuous high PRF waveforms for challenging environments
Jaroszewski, Steven; Corbeil, Allan; Ryland, Robert; Sobota, David
2017-05-01
Current airborne radar systems segment the available time-on-target during each beam dwell into multiple Coherent Processing Intervals (CPIs) in order to eliminate range eclipsing, solve for unambiguous range, and increase the detection performance against larger Radar Cross Section (RCS) targets. As a consequence, these radars do not realize the full Signal-to-Noise Ratio (SNR) increase and detection performance improvement that is possible. Continuous High Pulse Repetition Frequency (HPRF) waveforms and processing enables the coherent integration of all available radar data over the full time-on-target. This can greatly increase the SNR for air targets at long range and/or with weak radar returns and significantly improve the detection performance against such targets. TSC worked with its partner KeyW to implement a Continuous HPRF waveform in their Sahara radar testbed and obtained measured radar data on both a ground vehicle target and an airborne target of opportunity. This experimental data was processed by TSC to validate the expected benefits of Continuous HPRF waveforms.
Continuity of Landsat observations: Short term considerations
Wulder, M.A.; White, Joanne C.; Masek, J.G.; Dwyer, J.; Roy, D.P.
2011-01-01
As of writing in mid-2010, both Landsat-5 and -7 continue to function, with sufficient fuel to enable data collection until the launch of the Landsat Data Continuity Mission (LDCM) scheduled for December of 2012. Failure of one or both of Landsat-5 or -7 may result in a lack of Landsat data for a period of time until the 2012 launch. Although the potential risk of a component failure increases the longer the sensor's design life is exceeded, the possible gap in Landsat data acquisition is reduced with each passing day and the risk of Landsat imagery being unavailable diminishes for all except a handful of applications that are particularly data demanding. Advances in Landsat data compositing and fusion are providing opportunities to address issues associated with Landsat-7 SLC-off imagery and to mitigate a potential acquisition gap through the integration of imagery from different sensors. The latter will likely also provide short-term, regional solutions to application-specific needs for the continuity of Landsat-like observations. Our goal in this communication is not to minimize the community's concerns regarding a gap in Landsat observations, but rather to clarify how the current situation has evolved and provide an up-to-date understanding of the circumstances, implications, and mitigation options related to a potential gap in the Landsat data record. ?? 2010.
Calculus of continuous matrix product states
Haegeman, Jutho; Cirac, J. Ignacio; Osborne, Tobias J.; Verstraete, Frank
2013-08-01
We discuss various properties of the variational class of continuous matrix product states, a class of Ansatz states for one-dimensional quantum fields that was recently introduced as the direct continuum limit of the highly successful class of matrix product states. We discuss both attributes of the physical states, e.g., by showing in detail how to compute expectation values, as well as properties intrinsic to the representation itself, such as the gauge freedom. We consider general translation noninvariant systems made of several particle species and derive certain regularity properties that need to be satisfied by the variational parameters. We also devote a section to the translation invariant setting in the thermodynamic limit and show how continuous matrix product states possess an intrinsic ultraviolet cutoff. Finally, we introduce a new set of states, which are tangent to the original set of continuous matrix product states. For the case of matrix product states, this construction has recently proven relevant in the development of new algorithms for studying time evolution and elementary excitations of quantum spin chains. We thus lay the foundation for similar developments for one-dimensional quantum fields.

Altering the optics in one section of a linear accelerator beamline will in general cause an alteration of the optics in all downstream sections. In circular accelerators, changing the optical properties of any beamline element will have an impact on the optical functions throughout the whole machine. In many cases, however, it is desirable to change the optics in a certain beamline section without disturbing any other parts of the machine. Such a local optics manipulation can be achieved by adjusting a number of additional corrector magnets that restore the initial optics after the manipulated section. In that case, the effect of the manipulation is confined in the region between the manipulated and the correcting beamline elements. Introducing a manipulation continuously, while the machine is operating, therefore requires continuous correction functions to be applied to the correcting quadrupole magnets. In this paper we present an analytic approach to calculate such continuous correction functions for six quadrupole magnets by means of a homotopy method. Besides a detailed derivation of the method, we present its application to an algebraic example, as well as its implementation at the seeding experiment sFLASH at the free-electron laser FLASH located at DESY in Hamburg.

Biotechnological processes (BTP) involve living organisms. In the anaerobic fermentation (biogas production process) the organic matter is mineralized by microorganisms into biogas (methane and carbon dioxide) in the absence of oxygen. The biogas is an additional energy source. Generally this process is carried out as a continuous BTP. It has been widely used in life process and has been confirmed as a promising method of solving some energy and ecological problems in the agriculture and industry. Because of the very restrictive on-line information the control of this process in continuous mode is often reduced to control of the biogas production rate or the concentration of the polluting organic matter (de-pollution control) at a desired value in the presence of some perturbations. Investigations show that classical linear controllers have good performances only in the linear zone of the strongly non-linear input-output characteristics. More sophisticated robust and with variable structure (VSC) controllers are studied. Due to the strongly non-linear dynamics of the process the performances of the closed loop system may be degrading in this case. The aim of this paper is to investigate different linearizing algorithms for control of a continuous non-linear methane fermentation process using the dilution rate as a control action and taking into account some practical implementation aspects.

We have successfully used continuous microwave flow synthesis (CMFS) technique for the template free synthesis of mesoporous hydroxyapatite. The continuous microwave flow reactor consisted of a modified 2.45 GHz household microwave, peristaltic pumps and a Teflon coil. This cost effective and efficient system was exploited to produce semi-crystalline phase pure nano-sized hydroxyapatite. Effect of microwave power, retention time and the concentration of reactants on the phase purity, degree of crystallinity and surface area of the final product was studied in detail. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) were used to study the phase purity and composition of the product, while transmission electron microscopy (TEM) was used to study the effect of process parameters on the morphology of hydroxyapatite. The TEM analysis confirmed the formation of spherical particles at low microwave power; however the morphology of the particles changed to mesoporous needle and rod-like structure upon exposing the reaction mixture to higher microwave power and longer retention time inside the microwave. The in-vitro ion dissolution behavior of the as synthesized hydroxyapatite was studied by determining the amount of Ca{sup 2+} ion released in SBF solution. - Highlights: • Continuous microwave flow synthesis method was used to prepare hydroxyapatite. • Increase in microwave power enhanced the degree of crystallinity. • TEM images confirmed the presence of mesopores on the surface of HA.

Full Text Available Abstract Background The Turkish Association of Medicine founded a Continuing Medical Education Accreditation Committee in 1993 to evaluate and accredit scientific meetings and publications. The aims of this project were to raise the standards of meetings and to introduce compulsory revalidation and re-certification for physicians in Turkey. Discussion Since the year 1994, 2348 applications to the Continuing Medical Education board have been made (mostly for scientific meetings, and 95% of these applications have been accepted. Physicians received 139.014 credits during this time. This number is increasing every year. Meeting organisers' demand for such a kind of evaluation is increasing, because participants increasingly request it. Summary Efforts for revalidation and re-certification of physicians have not been completely successful yet. In the near future the Co-ordination Council of Medical Speciality Societies is going to oblige member associations to establish speciality boards. This will be the first step to the conventional use of Continuing Medical Education credits in occupational evaluation. Time-limited re-certification of physicians is the principal goal of Turkish Medical Association. Efforts to implement this change in legislation are being made.

Pregnancy is a unique period to quit smoking and alcohol consumption and although motivated, not all women succeed at this. We investigated the associations of personality with continued smoking and continued alcohol consumption during early pregnancy. In addition, we studied whether antenatal anxiety and depressive symptoms can explain these associations. Two antenatal measurements from the population-based Pregnancy Anxiety and Depression cohort study were used. Pregnant women in their first trimester were recruited via midwifery practices and hospitals. We analyzed a sample of women who continued (n=101) or quit smoking (n=254), and a sample of women who continued (n=110) or quit alcohol consumption (n=1230). Measures included questions about smoking, alcohol consumption, the NEO-Five Factor Inventory (personality), the State Trait Anxiety Inventory, and the Edinburgh Postnatal Depression Scale. We found associations between continued alcohol consumption and higher levels of openness to experience, and lower levels of conscientiousness (psmoking emerged. This study contributes to the limited literature on personality differences between women who continue and quit smoking and alcohol consumption during early pregnancy. General population studies have not confirmed the association between openness to experience and alcohol consumption which implies that pregnancy is indeed a unique period. Increased insight in how personality influences continued smoking and alcohol consumption during pregnancy can help health professionals to improve lifestyle interventions targeted at pregnant women.
Continuous normothermic retrograde cardioplegia for valve surgery.

1994-07-01
We have studied warm heart surgery, deemed as continuous warm blood cardioplegia and normothermic cardiopulmonary bypass (CPB), as an alternative to the technique of intermittent cold cardioplegia for valvular surgery. Between August 1990 and January 1994, 137 consecutive patients underwent valve repair or replacement using normothermic CPB. Eighty-six of these patients received continuous normothermic retrograde blood cardioplegia via the coronary sinus (CNRC). Fifty-one patients received intermittent cold blood cardioplegia (ICBC). All procedures were performed by the same surgeon (RWMF). The two groups were matched for age, sex, NYHA class, preoperative ejection fraction, diagnosis, procedure and activated clotting time. Warm blood cardioplegia was delivered continuously via the coronary sinus after antegrade arrest (oxygenated blood 1:4 to 1:3, 37 degrees C, 250-300 ml/min, maintaining coronary sinus pressures of 40-60 mmHg. Perioperative myocardial infarction was significantly less prevalent (4.6 vs. 8.0%; p < 0.05) in the warm cardioplegia group. Cardiac output immediately after bypass was significantly higher than before bypass only in the CNRC group (4.1 +/- 0.8 to 5.2 +/- 0.9 L/min; p < 0.01). CNRC patients had significantly higher incidence of spontaneous resumption of sinus rhythm at cross-clamp removal (80 of 86, 93%) compared to the hypothermic patients (14 of 51, 27%, p < 0.001). The time from removal of the aortic cross-clamp to discontinuation of CPB (reperfusion time) was significantly shorter in the warm cardioplegia group (43 +/- 7.4 versus 75 +/- 10.2 min; p < 0.001.(ABSTRACT TRUNCATED AT 250 WORDS)
The fluid mechanics of continuous flow electrophoresis
Saville, D. A.
1990-01-01
The overall objective is to establish theoretically and confirm experimentally the ultimate capabilities of continuous flow electrophoresis chambers operating in an environment essentially free of particle sedimentation and buoyancy. The efforts are devoted to: (1) studying the effects of particle concentration on sample conductivity and dielectric constant. The dielectric constant and conductivity were identified as playing crucial roles in the behavior of the sample and on the resolving power and throughput of continuous flow devices; and (2) improving the extant mathematical models to predict flow fields and particle trajectories in continuous flow electrophoresis. A dielectric spectrometer was designed and built to measure the complex dielectric constant of a colloidal dispersion as a function of frequency between 500 Hz and 200 kHz. The real part of the signal can be related to the sample's conductivity and the imaginary part to its dielectric constant. Measurements of the dielectric constants of several different dispersions disclosed that the dielectric constants of dilute systems of the sort encountered in particle electrophoresis are much larger than would be expected based on the extant theory. Experiments were carried out to show that, in many cases, this behavior is due to the presence of a filamentary structure of small hairs on the particle surface. A technique for producing electrokinetically ideal synthetic latex particles by heat treating was developed. Given the ubiquitous nature of hairy surfaces with both cells and synthetic particles, it was deemed necessary to develop a theory to explain their behavior. A theory for electrophoretic mobility of hairy particles was developed. Finally, the extant computer programs for predicting the structure of electro-osmotically driven flows were extended to encompass flow channels with variable wall mobilities.
MAP estimators for piecewise continuous inversion
Dunlop, M. M.; Stuart, A. M.
2016-10-01
We study the inverse problem of estimating a field u a from data comprising a finite set of nonlinear functionals of u a , subject to additive noise; we denote this observed data by y. Our interest is in the reconstruction of piecewise continuous fields u a in which the discontinuity set is described by a finite number of geometric parameters a. Natural applications include groundwater flow and electrical impedance tomography. We take a Bayesian approach, placing a prior distribution on u a and determining the conditional distribution on u a given the data y. It is then natural to study maximum a posterior (MAP) estimators. Recently (Dashti et al 2013 Inverse Problems 29 095017) it has been shown that MAP estimators can be characterised as minimisers of a generalised Onsager-Machlup functional, in the case where the prior measure is a Gaussian random field. We extend this theory to a more general class of prior distributions which allows for piecewise continuous fields. Specifically, the prior field is assumed to be piecewise Gaussian with random interfaces between the different Gaussians defined by a finite number of parameters. We also make connections with recent work on MAP estimators for linear problems and possibly non-Gaussian priors (Helin and Burger 2015 Inverse Problems 31 085009) which employs the notion of Fomin derivative. In showing applicability of our theory we focus on the groundwater flow and EIT models, though the theory holds more generally. Numerical experiments are implemented for the groundwater flow model, demonstrating the feasibility of determining MAP estimators for these piecewise continuous models, but also that the geometric formulation can lead to multiple nearby (local) MAP estimators. We relate these MAP estimators to the behaviour of output from MCMC samples of the posterior, obtained using a state-of-the-art function space Metropolis-Hastings method.
Fast, Continuous Audiogram Estimation Using Machine Learning.
Song, Xinyu D; Wallace, Brittany M; Gardner, Jacob R; Ledbetter, Noah M; Weinberger, Kilian Q; Barbour, Dennis L
2015-01-01
Pure-tone audiometry has been a staple of hearing assessments for decades. Many different procedures have been proposed for measuring thresholds with pure tones by systematically manipulating intensity one frequency at a time until a discrete threshold function is determined. The authors have developed a novel nonparametric approach for estimating a continuous threshold audiogram using Bayesian estimation and machine learning classification. The objective of this study was to assess the accuracy and reliability of this new method relative to a commonly used threshold measurement technique. The authors performed air conduction pure-tone audiometry on 21 participants between the ages of 18 and 90 years with varying degrees of hearing ability. Two repetitions of automated machine learning audiogram estimation and one repetition of conventional modified Hughson-Westlake ascending-descending audiogram estimation were acquired by an audiologist. The estimated hearing thresholds of these two techniques were compared at standard audiogram frequencies (i.e., 0.25, 0.5, 1, 2, 4, 8 kHz). The two threshold estimate methods delivered very similar estimates at standard audiogram frequencies. Specifically, the mean absolute difference between estimates was 4.16 ± 3.76 dB HL. The mean absolute difference between repeated measurements of the new machine learning procedure was 4.51 ± 4.45 dB HL. These values compare favorably with those of other threshold audiogram estimation procedures. Furthermore, the machine learning method generated threshold estimates from significantly fewer samples than the modified Hughson-Westlake procedure while returning a continuous threshold estimate as a function of frequency. The new machine learning audiogram estimation technique produces continuous threshold audiogram estimates accurately, reliably, and efficiently, making it a strong candidate for widespread application in clinical and research audiometry.
NSI directed to continue SPAN's functions
Rounds, Fred
1991-01-01
During a series of network management retreats in June and July 1990, representatives from NASA Headquarters Codes O and S agreed on networking roles and responsibilities for their respective organizations. The representatives decided that NASA Science Internet (NSI) will assume management of both the Space Physics Analysis Network (SPAN) and the NASA Science Network (NSN). SPAN is now known as the NSI/DECnet, and NSN is now known as the NSI/IP. Some management functions will be distributed between Ames Research Center (ARC) and Goddard Space Flight Center (GSFC). NSI at ARC has the lead role for requirements generation and networking engineering. Advanced Applications and the Network Information Center is being developed at GSFC. GSFC will lead the NSI User Services, but NSI at Ames will continue to provide the User Services during the transition. The transition will be made as transparent as possible for the users. DECnet service will continue, but is now directly managed by NSI at Ames. NSI will continue to work closely with routing center managers at other NASA centers, and has formed a transition team to address the change in management. An NSI/DECnet working group had also been formed as a separate engineering group within NSI to plan the transition to Phase 5, DECnet's approach to Open System Integration (OSI). Transition is not expected for a year or more due to delays in produce releases. Plans to upgrade speeds in tail circuits and the backbone are underway. The proposed baseline service for new connections is up to 56 Kbps; 9.6 Kbps lines will gradually be upgraded as requirements dictate. NSI is in the process of consolidating protocol traffic, tail circuits, and the backbone. Currently NSI's backbone is fractional T1; NSI will go to full T1 service as soon as it is feasible.
Symplectic embeddings and continued fractions: a survey
McDuff, Dusa
2009-01-01
As has been known since the time of Gromov's Nonsqueezing Theorem, symplectic embedding questions lie at the heart of symplectic geometry. After surveying some of the most important ways of measuring the size of a symplectic set, these notes discuss some recent developments concerning the question of when a 4-dimensional ellipsoid can be symplectically embedded in a ball. This problem turns out to have unexpected relations to the properties of continued fractions and of exceptional curves in blow ups of the complex projective plane. It is also related to questions of lattice packing of planar triangles.

An approximate solution of the refinement equation was given by its mask, and the approximate sampling theorem for bivariate continuous function was proved by applying the approximate solution. The approximate sampling function defined uniquely by the mask of the refinement equation is the approximate solution of the equation, a piece-wise linear function, and posseses an explicit computation formula. Therefore the mask of the refinement equation is selected according to one' s requirement, so that one may controll the decay speed of the approximate sampling function.
Forgetfulness of continuous Markovian quantum channels
Lupo, Cosmo; Mancini, Stefano
2009-01-01
The notion of forgetfulness, used in discrete memory quantum channels, is slightly weakened in order to be applied to the case of continuous channels. This is done in the context of quantum memory channels with Markovian noise. As a case study, we apply the notion of weak-forgetfulness to a bosonic memory channel with additive noise. A suitable encoding and decoding unitary transformation allows us to unravel the effects of the memory, hence the channel capacities can be computed using known results from the memoryless setting.

2008-01-01
We study the networking effects on the population divergence and the increased level of cooperation in the continuous snowdrift game (CSG). In the regular world, limited interaction inhibits the occurrence of evolutionary branching. The formation of clusters defends the intermediate-investors from intruding by high- or low-investors. In a rewired network, the collective behaviour is related to the rewiring rules. A linear relationship I = ασ + b between the average investment and the standard deviation of the degree distribution is found.

Evolution of zinc morphology during continuous electrodeposition
Institute of Scientific and Technical Information of China (English)
无
2003-01-01
The morphology evolution of zinc continuous electrodeposits with nano-sized crystals on the ferrite substrate has been studied by in-situ scanning tunnel spectroscopy (STM). It is found that the morphology of zinc electrodeposits varies from initial granules with a size of about 30 nm to layered platelets with increasing deposition time. Meanwhile, the crystal structure of the zinc electrodeposits is identified to be hexagonal η-phase by X-ray diffraction. The orientation relationship between zinc crystals and the substrate surface can be interpreted in terms of the misfit and the atomic correspondence of the interphase boundary between the η-phase deposits and α-Fe substrate.

1968-01-01
The continuous production of Clostridium tetani toxin has been carried out in a 1-liter stirred culture vessel for as long as 65 days. Toxin production of approximately 120 flocculating units per ml was maintained with a dilution rate of 0.125 hr-1, a temperature of 34 C, a pH of 7.4, and the addition to the medium of 0.1 g of potassium chloride per liter. The average minimal lethal intraperitoneal dose of the toxin in mice was approximately 106 per ml. PMID:4865906

2015-09-01
This paper reformulates the stochastic string model of Santa-Clara and Sornette using stochastic calculus with continuous semimartingales. We present some new results, such as: (a) the dynamics of the short-term interest rate, (b) the PDE that must be satisfied by the bond price, and (c) an analytic expression for the price of a European bond call option. Additionally, we clarify some important features of the stochastic string model and show its relevance to price derivatives and the equivalence with an infinite dimensional HJM model to price European options.

Radiation Reaction in a Continuous Focusing Channel
Huang, Zhirong; Chen, Pisin; Ruth, Ronald D.
1995-03-01
We show that the radiation damping rate of the transverse action of a particle in a straight, continuous focusing system is independent of the particle energy, and that no quantum excitation is induced. This absolute damping effect leads to the existence of a transverse ground state to which the particle inevitably decays and yields the minimum beam emittance that one can ever attain, γɛmin = /2mc, limited only by the uncertainty principle. Because of adiabatic invariance, the particle can be accelerated along the focusing channel in its ground state without any radiation energy loss.

Time, physics, and the paradoxes of continuity
Steinberg, D A
2003-01-01
A recent article in this journal proposes a radical reformulation of classical and quantum dynamics based on a perceived deficiency in current definitions of time. The argument is incorrect but the errors highlight aspects of the foundations of mathematics and physics that are commonly confused and misunderstood. For this reason, the article provides an important and heuristic opportunity to reexamine the types of time and non-standard analysis. This paper will discuss the differences between physical time and experiential time and explain how an expanded system of real analysis containing infinitesimals can resolve the paradoxes of continuity without sacrificing the modern edifice of mathematical physics.
Witnessing Continuous Variable Entanglement with Discrete Measurements
Schneeloch, James; Howland, Gregory A; Broadbent, Curtis J; Howell, John C
2012-01-01
In this Letter, we derive an entropic Einstein-Podolsky-Rosen (EPR) steering inequality for continuous variable (CV) systems using only experimentally measured discrete probability distributions and details of the measurement apparatus. We use this inequality to witness entanglement between the positions and momenta of photon pairs generated in spontaneous parametric downconversion (SPDC). We examine the asymmetry between parties in this inequality, and show that this asymmetry can be used to reduce the technical requirements of experimental setups intended to witness entanglement. Furthermore, we develop a more stringent steering inequality that is symmetric between parties, and use it to witness symmetric EPR steering.

The monthly report issued by CANSI on June 27 says that from January to May this year,the economic operation of China's shipbuilding industry kept a stable situation with twodigit growth of major economic indexes.However,under the impact of such adverse elements as slowing down of foreign demands,appreciation of domestic currency,rise of integrated cost and tightening up of fund supply,China's backlog order size continued to shrink,necessitating readjustment without hesitation of ship product structure.
Bayesian parameter estimation by continuous homodyne detection
Kiilerich, Alexander Holm; Mølmer, Klaus
2016-09-01
We simulate the process of continuous homodyne detection of the radiative emission from a quantum system, and we investigate how a Bayesian analysis can be employed to determine unknown parameters that govern the system evolution. Measurement backaction quenches the system dynamics at all times and we show that the ensuing transient evolution is more sensitive to system parameters than the steady state of the system. The parameter sensitivity can be quantified by the Fisher information, and we investigate numerically and analytically how the temporal noise correlations in the measurement signal contribute to the ultimate sensitivity limit of homodyne detection.
Modelling with twice continuously differentiable functions
Directory of Open Access Journals (Sweden)
Sanjo Zlobec
2014-03-01
Full Text Available Many real life situations can be described using twice continuously differentiable functions over convex sets with interior points. Such functions have an interesting separation property: At every interior point of the set they separate particular classes of quadratic convex functions from classes of quadratic concave functions. Using this property we introduce new characterizations of the derivative and its zero points. The results are applied to the study of sensitivity of the Cobb-Douglas production function. They are also used to describe the least squares solutions in linear and nonlinear regression.
Continuity Properties of Distances for Markov Processes
DEFF Research Database (Denmark)
Jaeger, Manfred; Mao, Hua; Larsen, Kim Guldstrand
2014-01-01
In this paper we investigate distance functions on finite state Markov processes that measure the behavioural similarity of non-bisimilar processes. We consider both probabilistic bisimilarity metrics, and trace-based distances derived from standard Lp and Kullback-Leibler distances. Two desirable...... continuity properties for such distances are identified. We then establish a number of results that show that these two properties are in conflict, and not simultaneously fulfilled by any of our candidate natural distance functions. An impossibility result is derived that explains to some extent...
Dense topological spaces and dense continuity
Aldwoah, Khaled A.
2013-09-01
There are several attempts to generalize (or "widen") the concept of topological space. This paper uses equivalence relations to generalize the concept of topological space via the concept of equivalence relations. By the generalization, we can introduce from particular topology on a nonempty set X many new topologies, we call anyone of these new topologies a dense topology. In addition, we formulate some simple properties of dense topologies and study suitable generalizations of the concepts of limit points, closeness and continuity, as well as Jackson, Nörlund and Hahn dense topologies.

DEFF Research Database (Denmark)
Adler-Nissen, Jens
2007-01-01
A new process for continuous stir-frying in industrial scale has been developed for producing convenience high-quality vegetables. The understanding of the dynamics of heat and mass transfer during stir-frying is crucial for up-scaling and controlling the process. The effect of different factors...... of loosely bound water from the vegetables allows the products to be frozen and re-heated without drip loss, and it is also an advantage when using them as ingredients in composite foods, such as pâtés. Examples developed by a professional chef indicate that he saved up to half of the cooking time compared...
Analytic continuation of functional renormalization group equations
Floerchinger, Stefan
2012-01-01
Functional renormalization group equations are analytically continued from imaginary Matsubara frequencies to the real frequency axis. On the example of a scalar field with O(N) symmetry we discuss the analytic structure of the flowing action and show how it is possible to derive and solve flow equations for real-time properties such as propagator residues and particle decay widths. The formalism conserves space-time symmetries such as Lorentz or Galilei invariance and allows for improved, self-consistent approximations in terms of derivative expansions in Minkowski space.
Continuous ambulatory peritoneal dialysis: no longer experimental.
WU, G.; Khanna, R.; Vas, S I; Digenis, G.; Oreopoulos, D G
1984-01-01
Many patients with end-stage renal disease have now been maintained for 5 years or more with continuous ambulatory peritoneal dialysis (CAPD). Viewed initially as an experimental alternative to be used only when hemodialysis was not feasible, CAPD is now seen as the treatment of choice in an increasing number of situations. CAPD is suitable for self-care. The main concern in the early years--peritonitis--is now less frightening and less frequent (one episode occurring every 18 patient-months ...

Designers of software for safety-critical applications are impelled to supplement their education through continuing engineering studies in the areas of requirements analysis, hazard identification, risk analysis, fault tolerance, failure modes, and psychology. Today`s complex level of design is contributing to opportunities for catastrophic design errors in computer functions where failure of such functions is capable of causing injury and death. A syllabus of post-graduate, core studies within the curricula of five engineering specialties is suggested. Software Engineers are exhorted to undertake a professional, responsible role in safety-critical software design.

Singular Continuous Spectrum for Singular Potentials
Jitomirskaya, Svetlana; Yang, Fan
2017-01-01
We prove that Schrödinger operators with meromorphic potentials {(H_{α,θ}u)_n=u_{n+1}+u_{n-1}+ g(θ+nα)/f(θ+nα) u_n} have purely singular continuous spectrum on the set {{E: L(E) Lyapunov exponent. This extends results of Jitomirskaya and Liu (Arithmetic spectral transitions for the Maryland model. CPAM, to appear) for the Maryland model and of Avila,You and Zhou (Sharp Phase transitions for the almost Mathieu operator. Preprint, 2015) for the almost Mathieu operator to the general family of meromorphic potentials.

Scaling Concepts in Describing Continuous Phase Transitions
Indian Academy of Sciences (India)
2016-10-01
Phase transitions, like the boiling of water upon increasingtemperature, are a part of everyday experience and are yet,upon closer inspection, unusual phenomena, and reveal a hostof fascinating features. Comprehending key aspects of phasetransitions has lead to the uncovering of new ways of describingmatter composed of large numbers of interacting elements,which form a dominant way of analysis in contemporarystatistical mechanics and much else. An introductorydiscussion is presented here of the concepts of scaling, universalityand renormalization, which forms the foundation ofthe study of continuous phase transitions, such as the spontaneousmagnetization of ferromagnetic substances.
