Der volle Inhalt der QuelleAnnotation:
In object oriented programming (OOP) class objects are individual units of code that encapsulate the desired functionality of each object. AOP is an attempt to handle the cross-cutting concerns that represent functionality needed by a class, but is not specific to that class. The cross-cutting functionality is implemented in AOP by using a class-like structure, the aspect. Aspects do not have their own context and as such are dependent upon other objects for their context. By not having their own context it is difficult to test the functionality of aspects. This study investigated the effectiveness of using class interfaces and mock objects to unit test aspects. This was accomplished by having the mock object inherit from the same interface as the base code, so that the mock object could be swapped in for the aspect.

This thesis deals with a general investigation and comparison of methods of solution of the unit commitment problem for thermal generating units. An intensive mathematical model for this problem has been developed and presented. The most commonly implemented methods for solving the problem of unit commitment were reviewed and discussed. Every reviewed method had been coded in FORTRAN 77 on a VAX11/785 machine. On the basis of the results obtained, a comprehensive comparison of the different methods ha; been carried out. For the comparison to be realistic and practical, each method was tested on three power systems of different sizes. As a result of the comparison, the unit commitment problem for a case study system has been solved by using the most appropriate method(s) from those discussed in the thesis. A new approach for solving the problem has also been proposed and tested.

Thesis (MBA)--Stellenbosch University, 2005.ENGLISH ABSTRACT: To compete in today’s ”new” economy, Centocor R&D SCH has to attain and maintain a competitive advantage within the global Pharma/biotech industry. With their drive to become a centre of excellence in the fields of fill-finish of biologics and particle characterization, it is important that an analysis of the status quo be done, and that efficient systems and structures are implemented to achieve world class performance. In this project, the approach to business excellence is discussed. Business excellence is more than a simple accumulation of a range of best practices. It can only be achieved by implementing a structured approach towards business performance. This begins with an internal self-assessment; as well as an assessment of the customer/partner needs: these of which are incorporated into the organization’s policies and strategies. Their perceptions are evaluated since these “quality chains” are what ultimately drive a business. The organization must align its culture, processes, inputs, and capabilities with the vision, goals and strategy; and promote and display a mind-set for innovation, and continuous improvement. In this way, the desired business results may be achieved. This is all driven by leadership; and a quality and performance culture; and provides an opportunity to view the organization holistically. The developed model for Centocor R&D SCH is a framework for measuring their business excellence towards achieving performance excellence, and from there a well-paved route for developing the centre of excellence. It is developed on the basis of the European Foundation for Quality Management Model as well as that of the global J&J Process Excellence Competitive Assessment Model; and is supported by the criteria that support those. Strengths are identified, and areas of improvement are viewed as opportunities where the teams can improve on to ensure leadership and excellence in those arenas.
AFRIKAANSE OPSOMMING: Om in vandag se “nuwe” ekonomie mededinge te kan wees, moet Centocor R&D SCH ‘n mededingende voordeel in die globale farmakologiese/biotegnologie industrieë bereik en handhaaf. Met die dryfveer om ‘n sentrum van uitnemendheid in die velde van lyofilisasie and partikel karakterisasie te word, is dit belangrik dat ‘n ontleding oor die status quo gedoen word, en dat doeltreffende stelsels en strukture geïmplementeer word om wereldklas prestasies te behaal. In hierdie projek word die benadering om tot sake-uitnemendheid te vorder, bespreek. Sake-uitnemendheid is meer as net ‘n eenvoudige akkumulaise van ‘n reeks beste praktyke. Dit kan slegs bereik word deur die implementering van ‘n gestruktureerde benadering tot sake resultate. Hierdie proses begin met ‘n interne self-ondersoek, asook ‘n beoordeling van die behoeftes van kliënte en vennote: dit wat in die organisasie se se beleide en strategieë geïnkorporeer is. Hulle persepsies word ge-evalueer want dit is juis hierdie waardekettings wat uiteindelik die sake-onderneming voortstu. Die organisasie moet sy kultuur, prosesse, insette en vermoeëns met die visie, doelwitte en strategie belyn; en ‘n ingesteldheid op innovasie en deurlopende verbetering toon en uitbou. Op so ‘n manier kan die gewensde sake resultate behaal word. Dit word alles beheers deur leierskap en ‘n kultuur van kwaliteit en prestasie, en skep die geleentheid om die organisasie holistoes te benader. Die model wat vir Centocor R&D SCH ontwikkel is, is ‘n raamwerk waarmee hulle hul sake-uitnemendheid kan meet, met die oog om uitmuntende prestasie te lewer, en om van daar af tot ‘n sentrum van uitnemendheid te ontwikkel. Die model is gebasser op die European Foundation for Quality Management Model asook die globale J&J Process Excellence Competitive Assessment Model, en word gedar deur die criteria van daardie modelle. Sterkpunte word geïdentifiseer, en areas vir ontwikkeling word gesien as geleenthede vir die spanne om te verbeter en na leierskap en uitnemendheid in daardie gebied te streef.

In time series models, autoregressive processes are one of the most popular stochastic processes, which are stationary under certain conditions. In this study we consider nonstationary autoregressive models of order one, which have iid random errors. One of the important nonstationary time series models is the unit root process in AR (1), which simply implies that a shock to the system has permanent effect through time. Therefore, testing unit root is a very important problem.
However, under nonstationarity, any estimator of the autoregressive coefficient does not have a known exact distribution and the usual t &ndashstatistic is not accurate even if the sample size is very large. Hence,Wiener process is invoked to obtain the asymptotic distribution of the LSE under normality. The first four moments of under normality have been worked out for large n. In 1998, Tiku and Wong proposed the new test statistics and whose type I error and power values are calculated by using three &ndash
moment chi &ndash
square or four &ndash
moment F approximations. The test statistics are based on the modified maximum likelihood estimators and the least square estimators, respectively. They evaluated the type I errors and the power of these tests for a family of symmetric distributions (scaled Student&rsquo
s t). In this thesis, we have extended this work to skewed distributions, namely, gamma and generalized logistic.

Le Min-up/min-down Unit Commitment Problem (MUCP) consiste à trouver un plan de production de coût minimum pour un ensemble d’unités de production électrique sur un intervalle de temps discrétisé. A chaque pas de temps, la production totale doit satisfaire la demande prévue. Chaque unité respecte des temps minimum de marche et d’arrêt. Nous montrons que le MUCP est fortement NP-difficile, mettant ainsi en valeur l’impact du couplage dynamique des contraintes de demande sur la difficulté du problème. Pour appréhender cette difficulté, nous introduisons les inégalités interval up-set, généralisant les contraintes de min-up et les extended cover du sac à dos. Les facettes sont caractérisées, et un Branch & Cut est implémenté. Afin de briser les symétries du problème, nous définissons les sous-symétries comme des symétries apparaissant dans des sous-ensembles de solution. Nous considérons des PLNE dont les groupes de sous-symétrie sont des groupes symétriques agissant sur certaines sous-colonnes des matrices solutions. Nous proposons un cadre générique pour gérer les sous-symétries apparaissant dans ce type de problèmes. Deux techniques pour briser les sous-symétries sont proposées : la première est un algorithme de fixing orbitopal pour le full sub-orbitope, la seconde est basée sur des inégalités. Les résultats expérimentaux montrent que les techniques proposées sont plus performantes que les techniques de la littérature. Enfin, nous comparons différentes structures de décomposition pour le MUCP. Des bornes de bonne qualité sont obtenues par dualisation des contraintes dynamiques. Notre Branch&Price&Cut montre que les interval up-set sont utiles dans ce contexteThe Min-up/min-down Unit Commitment Problem (MUCP), is to find a minimum-cost production plan on a discrete time horizon for a set of units producing electric power. At each time period, the total production has to meet a forecast demand. Each unit must satisfy minimum up and down time constraints. We show that the MUCP is strongly NP-hard, thus highlighting that the dynamic coupling of demands by minimum up and down time constraints represents one major source of difficulty. To cope with this difficulty, we introduce interval up-set inequalities, a new class of valid inequalities for the MUCP polytope, generalizing both min-up and extended cover inequalities from the 0-1 knapsack polytope. Facet defining cases are characterized and a Branch & Cut algorithm is devised. To deal with the symmetries impairing the solution process, we define sub-symmetries, as symmetries arising from a solution subset. We focus on integer linear programs whose (sub-)symmetry groups are symmetric groups acting on sub-columns of solution matrices. We propose a general framework to handle sub-symmetries in such problems. On this basis, two symmetry-breaking techniques are introduced. The first technique is an orbitopal fixing algorithm for the full (sub-)orbitope. The second technique is based on sub-symmetry breaking inequalities. Experimental results on MUCP instances show that the proposed techniques outperform state-of-the-art techniques. Finally we compare various Dantzig-Wolfe structures for the MUCP. We show that good quality lower bounds can be obtained by dualization of time-coupling constraints. Branch & Price results show that interval up-set inequalities are useful in this context

We consider the use of a sieve bootstrap based on moving average (MA) and autoregressive moving average (ARMA) approximations to test the unit root hypothesis when the true Data Generating Process (DGP) is a general linear process. We provide invariance principles for these bootstrap DGPs and we prove that the resulting ADF tests are asymptotically valid. Our simulations indicate that these tests sometimes outperform those based on the usual autoregressive (AR) sieve bootstrap. We study the reasons for the failure of the AR sieve bootstrap tests and propose some solutions, including a modified version of the fast double bootstrap.We also argue that using biased estimators to build bootstrap DGPs may result in less accurate inference. Some simulations confirm this in the case of ADF tests. We show that one can use the GLS transformation matrix to obtain equations that can be used to estimate bias in general ARMA(p,q) models. We compare the resulting bias reduced estimator to a widely used bootstrap based bias corrected estimator. Our simulations indicate that the former has better finite sample properties then the latter in the case of MA models. Finally, our simulations show that using bias corrected or bias reduced estimators to build bootstrap DGP sometimes provides accuracy gains.

Coronary Heart Disease (CHD) is one of the major causes of morbidity and mortality in Scotland. One of the most frequently reported symptoms of CHD is chest pain which is often of sudden onset and severe in nature. The control of pain presents a challenge to nursing and medical staff as patients experience ongoing pain. This study sought to investigate the assessment and treatment of cardiac pain in a coronary care unit (CCU). Adequate assessment of pain is a fundamental step in its management. Within this study the process of communication with patients who had cardiac pain was assessed by measuring the duration, frequency and content of verbal communication between nurses and patients. Following attendance at an educational programme the staffs' behaviour was reassessed to evaluate any change. No significant difference was observed in the duration or frequency of interaction, but a change was observed in the quality of communication which occurred during pain assessment and the subsequent administration of opiates in CCU. Having attempted to improve the practice of nursing staff, a comparison of patient controlled analgesia (PCA) versus nurse administered analgesia for pain following myocardial infarction was performed for 48 hours. A significant reduction in pain intensity was reported in the PCA group. The PCA group also used significantly more analgesics particularly in the second 24 hour period. The use of PCA clearly demonstrated the problem of ongoing pain following myocardial infarction. An exploration of the levels of urinary catechoalmine secretion as an objective measure of pain was found to show no relationship to pain experience. The patients' views on the management of their pain and opinions of PCA was also explored. The results suggested that PCA removed the obstacles associated with the administration of analgesia in the conventional regime. It was readily accepted by both patients and staff in CCU and could be easily offered as a treatment option in the management of cardiac pain. This study has generated areas for further investigation which include the influence of alternative education strategies on pain management and the evaluation of PCA with other client groups, and in different clinical settings.

This study seeks to understand and examine the role of public policy units with a specific focus on the South African National Parliament Policy Management Unit (PMU). The problem being investigated is that of a lack of constructive support and debate in understanding the role and functions of policy management units. Thus, the scope of the study is limited to policy management units with the South African Parliament PMU as a special reference. The primary objective of this study is to investigate the role of policy management units, with particular reference to the PMU in the South African Parliament. The secondary objectives will then be to provide a theoretical perspective of the role and functions of policy management units
and to develop a case of the PMU in Parliament for further analysis and examination. Examples of existing policy units and the support they have with parliaments will be produced, assessed, and explored.

Este trabalho se concentra no desenvolvimento de mecanismos de leilões reveladores aleatorizados que buscam maximizar simultaneamente a receita e a eficiência econômica, ou função social, de leilões de demanda unitária. Em um leilão de demanda unitária, um conjunto de k bens é leiloado para um conjunto de n consumidores, com a restrição de que nenhum consumidor pode comprar mais de um bem. É apresentado um arcabouço para o desenvolvimento de mecanismos reveladores aleatorizados de complexidade polinomial derivados do mecanismo de Vickrey-Clarke- Groves, ou VCG. Ao invés de utilizar preços de reserva, estas variantes do VCG utilizam como parâmetro o número de bens que devem ser efetivamente vendidos. Os mecanismos se diferenciam entre si pela maneira como é feito o cálculo do número de bens que devem ser vendidos e permitem um balanço interessante entre receita e eficiência econômica, ao mesmo tempo que melhoram os resultados teóricos alcançados para o problema de Leilões de Demanda Unitária.
This work focuses on the development of randomized truthful mechanisms that seek to maximize both the revenue and the economic efficiency, or social welfare, of unit-demand auctions. In a unit-demand auction a set of k items is auctioned to a set of n consumers and no consumer can purchase more than one item. A framework is presented for devising polynomial-time randomized truthful mechanisms that are based on a new variant of the Vickrey-Clarke-Groves (VCG) mechanism. Instead of using reserve prices, this variant of VCG uses the number of objects that we wish to sell as a parameter. The mechanisms obtained differ er from each other in the way they select the number of items to be sold and allow an interesting trade-off between revenue and economic effciency, while improving upon the stateof- the-art results for the Unit-Demand Auction problem (09).

This thesis explores the early years of the British documentary movement as it formed within the Empire Marketing Board between 1926 and 1933. I begin by offering new insights into this formation by focusing on key institutions that have been under-researched in existing literature. The movement started with government money and resources, in a position formalised by the EMB's use of the Imperial Institute, a Victorian institution with an established history of public education, exhibition and research. Within this official institutional framework the EMB's filmmakers enjoyed an extraordinary level of creative freedom. They were simultaneously embedded within the'alternative' film culture that had developed from the independent screenings of the London Film Society (1925-1939). The Society offered coverage of the art and history of film for the first time in Britain, alongside showcasing a wealth of contemporaneous experimental and avant-Barde fiction and non-fiction work. Drawing on a variety of primary archival sources (some of which have not been previously explored) in the first three chapters I examine how the EMB's film unit developed in a relationship between the Board, the Imperial Institute and the Film Society. This position defined the work they produced, and the style and the content of their films for the EMB. The filmmakers were part of an Imperial discourse that aimed to promote Britain and the British Empire, however they were also engaging with, and contributing to, an international movement of filmmakers and intellectuals who were using documentary film to look closely at contemporary society from new perspectives. The fourth and fifth chapters offer fresh insights into filmmaking at the EMB, with a personal study based on new research into the life and work of Basil Wright. Although he was a central figure at the EMB, his role has remained under-researched. The material I present here offers a new account of the early formation of the documentary movement at the EMB and the original resources that the Board and its filmmakers drew upon.

The development of swimming was investigated in zebrafish aged 1.5 to 5 days postfertilization by examining both the swimming behavior and its generation by the nervous system. Upon hatching (at day 2), swimming is undirected and occurs in sustained bursts of high frequency (mean = 67 Hz) tail undulations. By 4 days, the swimming pattern matures to a more directed, less erratic, beat-and-glide pattern where slower (mean = 35 Hz) tail undulations, lasting ∼200 ms, alternate with longer gliding rest periods. Swimming is powered by two classes of embryonic muscles (embryonic red, ER and white, EW) that are electrically coupled within (but not between) classes and have physiological properties similar to vertebrate tonic and twitch muscle, respectively. ER fibers have a lower chloride ion permeability than EW fibers and do not have sodium dependent action potentials. In paralyzed preparations, motoneurons and muscle fibers received coordinated excitatory synaptic activity (with left to right alternation and head to tail propagation) corresponding to either burst or beat-and-glide swimming. ER muscle was de-recruited at the fastest swimming rates and EW fibers dropped out at the slowest swimming rates. Rhythmic motoneuron output was generated by a phasic glutamatergic and a largely tonic glycinergic synaptic drive. Glutamatergic synapses had either or both AMPA/kainate and NMDA receptors and the kinetics of these synaptic currents were fixed throughout the developmental period examined. When depolarized, motoneurons fired high frequency (up to 800 Hz) bursts of action potentials that rapidly accommodated (within ∼20 ms) due to voltage and calcium dependent outwardly rectifying conductances. These intrinsic motoneuron properties are hypothesized to interact with the rhythmic synaptic drive to pattern motor output (at ∼25--75 Hz) to locomotor muscles. The neural generation of swimming in developing zebrafish is thus fundamentally similar to locomotion in adu

This research project represents a continuation of the research programme into Precast Concrete Pavement Units, "P. C. P. U. ", which is based in the Department of Civil Engineering at the University of Newcastle upon Tyne. The units were referred to as raft units throughout the thesis which focused on the use of raft units as a full concrete paving system for aircraft parking, taxiway, and other low speed areas, at airports. The physical full scale test model was designed and constructed to represent the applied loading from one of the dual wheel legs of the design aircraft, a Boeing 727-200, when it is taxiing over a raft unit paving system. It was only possible for the test model to be provided with a contact area of 200 mm square compared to the real life of 400 mm square. A theoretical correction was applied to allow for this difference. Sixteen raft units were tested in pairs using the test model. The tests were divided into three modules to investigate the effect of the raft unit dimensions, Module(M1); the reinforcement design, Module(M2); and the raft thickness, Module(M3). The twin loading assembly applied a repetitive dynamic load which was moved manually between four different loading positions to represent the aircraft moving across the raft units. The primary aim of the experimental programme was to identify for the first time the fatigue life and failure mechanisms of the raft units under the influence of twin dynamic moving loads, and provide experimental results to enable a more refined numerical design method to emerge for raft units, as well as to determine the causes of failures and to recommend remedial measures. Observations were made of vertical deflection, concrete strains, crack widths and crack patterns, failure load, and failure modes, each of which were described in detail. The test observations showed that by increasing each of the following variables, namely, the aspect ratio, the amount of steel bar reinforcement and the thickness of the raft units, resulted in each case in an extension of raft unit life. It was found that some form of uplift restraint on the raft unit should be added to improve the fatigue life for one of the loading positions and that fibre reinforcement should not be used. The ultimate load capacity of the raft units was influenced by the loading position, the applied load level and the number of load repetitions, together with the crack patterns. Using the results from the raft units that had failed within a specific module, it was possible to predict the ultimate and reserve load capacity of raft units within the modules that were only partially fatigued. Four important conclusions have been established during the research project. Firstly, based on the test results, an empirical relationship was derived using regression analysis, relating the number of load repetitions to the aspect ratio, the amount of reinforcement, the raft thickness, and the applied loading. This will need further verification, but it should eventually be very useful when estimating the fatigue life of these specific raft unit models. Secondly, a new design method has been proposed. The design methods for raft units proposed previously by Bull, Ismail, Annang, Ackroyd, and the British Port Association were reviewed. The test results enabled a new design method to be developed which was based on Bull's method but proposed new design charts and tables for each of the raft units considered in the research project which introduced the additional variables of contact pressure and the exact loading position. Thirdly, the measured strains were used to develop strain fatigue relationships for designing raft units and estimating the reserve design life in a raft unit paving system for the purpose of maintenance management by relating the accumulated number of load repetitions of a design load to the permissible concrete strain. The strain fatigue equations were generated for each of the raft units considered in this research project. Thus, the most realistic way to control raft unit distress is through the use of a predictive fatigue model. This should prove invaluable to those involved in the maintenance of raft unit paving systems. Finally, life cycle cost analysis was conducted for three types of construction pavement (paving blocks, PQC, and raft units). The analysis demonstrated that the precast concrete raft units will become a viable alternative to conventional pavement construction and a real competitive to the concrete paving blocks.

The rapid growth of medical sciences and technologies created the need to manage data generated by sophisticated medical equipment (e.g. lab results, vital signs, etc.). This class of equipment, especially in the modern Intensive Care Unit (ICU), emits large quantities of latient data which medical staff usually records on log sheets.This thesis presents a database design that allows abstract definition of data types, and offers a unified view of data during the development phase, distinct levels of data management and a higher degree of system flexibility. This database model is an implementation of a database for a Patient Data Management System (PDMS) developed for use in the ICU of the Montreal Children's Hospital. The PDMS has a variety of application modules that handle and process various types of data according to functionality requirements.

This study addresses the strategic planning and environmental scanning activities of the hotel chains operating in Portugal, and compares attitudes towards planning and scanning activities by companies where strategy is formalised through a formal written strategic plan (intenders) and those companies where strategy is informally developed through a 'vision' or 'informal plan' (realisers). The main challenges facing Portuguese hoteliers as identified by the representatives of the Portuguese government, hotel associations and hotel chains inform the development of the study. The aims of the research derive from these challenges faced by the Portuguese hoteliers and their need for a more proactive attitude towards strategic planning, as well as from the literature on strategic planning and environmental scanning. The study is exploratory and descriptive based on a qualitative and inductive approach. This methodology is used to elicit and represent the existing practices as well as managers' perceptions towards strategic planning and environmental scanning. The fmdings reveal a lack of formal continuous environmental scanning by both formal and informal planning chains and a significant number of similarities in terms of the scanning methods and sources used by these two types of organisations. A grounded theory methodology is used to identif' the core themes emerging and to develop theory on the planning and scanning activities of hotel chains. The use of this methodology also allows a better understanding of the relationship between strategic planning and environmental scanning by hotel chains where strategy is intended (existence of a formal written strategic planning) and by those where strategy is realised (no existence of a formal written strategic planning). A cognitive mapping technique is used for the analysis of respondents' perceptions towards the development of a formal environmental scanning process. This technique is also applied in the identification of the relevance and structure of a formal environmental scanning process, in the assessment of the barriers to the development of this process as well as possible actions to overcome them. The study also finds that the existing differences amongst intenders and realisers rely essentially on aspects of content rather than on aspects of process, and that keeping a high degree of flexibility in the decision making process is considered of premium importance. The preponderance of similarities as opposed to differences lead to the development of a series of output propositions common to all four comparison groups. These propositions, together with other recommendations suggested in the literature, are used to identify the necessary conditions for the development and implementation of a continuous environmental scanning process by formal and informal planning hotel chains and develop a theoretical model of environmental scanning.

La première préoccupation de notre recherche concernait le processus de développement d’Abu Dhabi, tandis que la deuxième était relative aux effets de l’ultra-modernité sur la société traditionnelle. La première hypothèse que nous avons posée reflétait l’idée selon laquelle Abu Dhabi n’aurait été que le résultat d’une prospérité démesurée et d’un progrès technique adopté sans réflexion. Nous entendions également battre en brèche l’idée d’un abandon sans résistance des modes de vie ancestraux et d’une irrémédiable dépersonnalisation de la société émiratie. Nous avons pu démontrer que les Émiratis ont réussi à préserver leur identité et sont parvenus à se réinventer dans une acculturation où l’hyper-modernité ne fut pas que destructrice. Enfin, il a été question de mettre en exergue les efforts déployés par les gouverneurs pour sauvegarder les valeurs culturelles et l’identité d’une société originellement bédouine, face aux assauts de la modernisation et de la mondialisationThe first concern of our research was on the development process of Abu Dhabi, while the second was on the effects of the ultra-modernity on the traditional society. The first hypothesis rejected the idea that Abu Dhabi was the result of an excessive prosperity and technological progress adopted without thinking. We also discussed the idea of abandonment without resistance of the traditional ways of life and a depersonalization of the Emirati society. We have demonstrated that the Emiratis have managed to preserve their identity and have succeeded in reinventing themselves in an acculturation where the hyper-modernity was not just destructive. Finally, it was also our intent to highlight the efforts of governors to safeguard the cultural values and identity of a society originally Bedouin face to the modernization and globalization

This study aims to enlighten microfacies evolution and micropaleontological properties of the Tournaisian –
Visean boundary in Aladag Unit (Central Taurides, Turkey). Two sections comprising dark shale and dark limestone alternations, including a fairly dolomitized part towards their top are measured. The microfacies analysis suggests a subtidal depositional environment. Foraminiferal assemblages were distinguished at Section AP and biozonation was documented. The biozonation separates the measured section into three zones, described as A, B and C. Zone A is scarce foraminifera fauna, and mainly contains Earlandia sp. Zone B is defined by appearance of a diversified foraminifera fauna and the first appearance of Lugtonia monilis (Malakhova, 1955) with Eoparastaffella sp. (morphotype 1). Zone C is defined according to the first appearance of Eoparastaffella simplex (Vdovenko, 1964) (morphotype 2) and foraminifers Laxaendothyra ex. gr. laxa. Tournaisian &

In the electrophysiological evaluation of neuromuscular disorders, the number of active motor units in a muscle is considered one of the most important indicators of the physiological state of peripheral nerve/muscle systems. Electrophysiological techniques have been designed to estimate this number but, despite considerable effort, they only provide an approximation of the exact number. To assist further development in this field, the specific problem of the classification of stimulus-evoked potentials was investigated. Over 1300 series of signals were recorded from four subjects over a five-week period. From these data sets, those having clearly separable unique responses were selected and unsupervised learning methods were employed to identify the different response classes. The lowest misclassification error rate obtained under these conditions was 25%. A subsequent evaluation of an interactive graph-theoretic clustering technique presented interesting results with an error rate of 8%. The findings hold promise for developing better methods to estimate the number of motor units.

-elimination method. The two double-bond isomers 310 and 299b were synthesized as key compounds. Treatment of 310 with t-BuOK resulted in the formation of ketone 308 and diene 313. For the formation of 308, the cyclic allene 300 was proposed as an intermediate. Treatment of 299b, with t-BuOK gave arise to the diene 313 and the dimerization product 322. On the basis of density-functional-theory (DFT) calculations on the allene 300 and the alkyne 320, the formation of the latter as the intermediate was excluded. In the second part of study, the stability of endo-carbene 304 was investigated. Previous studies indicated, during the formation of intermediate 264, no exo-carbene 330 structure could be optimized in its free carbene form. At this point, we were curious about the stability of endo-cyclopropylidene 304 not discussed before in literature. First, addition of bromofluorocarbene to anti-7-ethylbenzonorbornadiene (352) was aimed to isolate the endo-adduct 302b. However, no carbene addition reaction was observed caused by pyramidalization on double bond respect to the methoxy derivative, 363b. Therefore, the bromine was introduced to C-7 carbon atom. Treatment of 302a with MeLi in the presence of furan, gave furan adduct 306a confirmed the formation of allene 305a as a reactive intermediate. Theoretical calculations showed endo-carbene 304a was optimized in the free carbene form . However, it readily isomerizes to allene 305a afforded furan adduct 306a.

Der volle Inhalt der QuelleAnnotation:
This thesis is devoted to the optimal commitment of generation units in an all-thermal, single or multiple area, power system. The problem, known as unit commitment, is a nonlinear mixed program typically with thousands of 0-1 integer variables and diverse constraints. An exact optimal solution to the problem is only possible via (explicit or implicit) enumeration, which requires a prohibitively long computation time for large problem instances.Two optimization approaches, Lagrangian relaxation and simulated annealing, are explored in this thesis for efficient and near-optimal unit commitment.
Lagrangian relaxation combines the solution of the dual of the unit commitment problem with feasibility search to obtain primal feasible solutions. The feasibility search is necessary because a solution to the dual seldom solves the primal, and because little theory is available to bridge the optimal dual and primal solutions. In this thesis, several new feasibility search procedures to find a near-optimal primal feasible solution from the dual solution are developed and tested. These procedures are independent of the data constituting different problem instances, and are more rigorous and systematic than the existing ones. With these procedures, Lagrangian relaxation is successfully and efficiently applied to both single and multiple area unit commitment.
Simulated annealing exploits the resemblance between a minimization process and the cooling of a molten metal. The method generates feasible solution points randomly and moves among these points following a strategy which leads to a global minimum in a statistical sense. Simulated annealing is very flexible for handling diverse and complicated constraints, such as those typical of the unit commitment problem. Simulated annealing is analyzed, evaluated and implemented for unit commitment in this thesis.
Five major algorithms, proposed in this thesis for unit commitment and reserve-constrained economic dispatch, are extensively tested and compared by numerical simulation on sample power systems of 10 to 100 units. The simulation results show the efficiency of the tested algorithms for large-scale unit commitment and demonstrate the general applicability of simulated annealing. A comparison with the priority list method and a study of the convergence rates of the subgradient type algorithms are also included in the simulation.

Der volle Inhalt der QuelleAnnotation:
This dissertation is concerned with software pipelining in the presence of resource constraints--both register and function unit. Software pipelining attempts to combine or schedule operations from different iterations of a loop into a new loop body which can execute as fast as possible or rate-optimally on a given architecture. Approaches for software pipelining can be categorized as exact--meaning the approach guarantees it will find a rate-optimal schedule--or inexact meaning the approach makes no such guarantee. This thesis proposes two novel and exact approaches.One approach represents the software pipelining problem as an Integer Linear Programming (ILP) problem. A unified framework is developed that includes both function unit and register constraints. This framework can represent both fully pipelined function units as well as function units with structural hazards. In the latter case, difficulties in mapping instructions to function units are identified and a solution developed.
Our other software pipelining approach is to enumerate a sufficiently large set of schedules so as to guarantee inclusion of a rate-optimal, minimum register schedule fitting the target architecture. As the set of legal schedules is often large or infinite, drastic pruning is required to make this approach feasible. Requirements for this pruning are developed which insure that the enumerated set still contains all schedules of interest. Both the enumeration and ILP approaches are easily adapted to handle resource minimization, making them suitable for use in synthesis and architectural definition as well as in compilers.
A powerful tested containing over 35,000 lines of C code was constructed to evaluate the proposed approaches against each other, as well as to compare them to a set of leading inexact methods. Performance was compared on over 1000 benchmark loops. For a significant number of the loops, use of the proposed ILP and enumeration techniques resulted in schedules that were faster and/or used fewer registers than the inexact methods.

Beginning with Jensen(1968), the evaluation of the investment performance of managed funds has been a major topic in Finance. This has not been without controversy, especially how the risk of the fund is to be measured. Evaluating portfolio performance has been closely associated with tests of market efficiency. Practically all of the theoretical and empirical studies have been conducted in the USA. The evaluation of fund performance in the UK has been limited. This study seeks to examine a number of issues in performance measurement using a sample of UK unit trusts. The study is organised as follows. Chapter 1 presents an overview of the performance measurement literature. The chapter describes Grinblatt and Titman's(l989) framework which provides the theoretical underpinnings of the study. Chapter 2 reports the tests of the ex ante mean-variance efficiency of a number of benchmark portfolios which are used to evaluate performance. Chapter 3 examines the performance of a sample of UK unit trusts using the Jensen(1968) measure against a number of benchmark portfolios. The chapter also considers the empirical significance of the potential timing biases in the Jensen measure. Chapter 4 presents evidence of the selectivity and timing performance of the trusts. Chapter 5 investigates the factors which may affect trust performance. These include the investment objective, size, expense ratios of the trusts. The final chapter presents the conclusions of the study.

With the introduction of programmable graphical processing units (GPU) in the last decade, Heterogeneous computing systems have become more popular. It has been predicted that by leveraging the power of the GPU's many cores, many applications can experience improved performance in the near future. However porting applications to the GPU in most cases cannot be automated due to the GPU's unique architecture. Mapping problems on the GPU has been researched in many diverse fields. Many problems in science and engineering come down to solving sparse systems of linear equations. Nevertheless conventional iterative solvers are not feasible tools for large sparse systems. One of the novel iterative solvers proposed in recent literature is the Gaussian belief propagation (GaBP) method. This method uses recursive message updates on a graphical model. In this work a variant of GaBP algorithm was implemented on the GPU. The implementation was successfully tested with FEM (finite element method) data. The parallel implementations achieved up to 4× improvement in execution time, compared to the serial CPU implementation.Avec l'introduction d'unités de traitement graphiques programmables (GPU) durant la dernière décennie, les systèmes informatiques hétérogènes sont devenus plus populaires. On pense qu'en exploitant la puissance des nombreux cœurs du GPU, de nombreuses applications pourront bénéficier de meilleures performances dans un avenir rapproché. Cependant, dans la plupart des cas le fait de porter des applications vers le GPU ne peut pas être automatisé à cause de l'architecture unique du GPU. Les problèmes de mappage sur le GPU ont été l'objet de recherches dans de nombreux domaines. Beaucoup de problèmes en science et en ingénierie consistent simplement à résoudre systèmes d'équations linéaires creux. Étant donné que les systèmes creux qui croissent à l'aide de solveurs itératifs classiques ne seront pas réalisables, un des nouveaux solveurs itératifs proposés dans la littérature récente est la méthode de croyance des propagations gaussiennes (GABP). Cette méthode utilise des messages de mise à jour récursifs sur un modèle graphique. Dans ce travail, une variante de l'algorithme GABP fut mise en place sur le GPU. La mise en œuvre a été testée avec succès avec des données FEM (méthode des éléments finis). Les implémentations parallèles ont atteint une amélioration du temps d'exécution jusqu'à 4 × par rapport à l'implémentation de série du CPU.

This master thesis presents a theoretical analysis of the interface between the Research&Development units and manufacturing. Streamlining this interface becomes more and more crucial for the smooth and high volume production. A literature research and a theoretical analysis of the crucial elements of inter-departmental communication between design and manufacturing build the basis for an improved communication model. The model acts as a guideline for the implementation of change processes. It emphasises the importance of both structural and individual elements of interventions. Both elements are important and necessary for the success, but their moment of result separates them. Hybrid methods counterbalance these differences. A first questionnaire issues the actual level of communication at the involved companies; a second questionnaire ascertains the attitude of the employees towards the proposed interventions. The model as a framework can be applied in general to all organisations, since the interventions that are necessary to be implemented are resulting from the analysis of the specific environments.

The specific aim of this study was to advance the development of the Minimally Structured & Modular Vertical Farm (MSM-VF), an original concept developed at The University of Arizona, by designing a specific modular unit made of a transparent-walled modified standard shipping container for use in climate locations represented by Los Angeles and New York City. The conclusions of the study included: (1) A workable range of temperatures (15 to 30°C) for cultivating tomato in Los Angeles and New York City could be achieved in a transparent-walled MSM-VF shipping-container modular unit by using a cover material of low density polyethylene (LDPE) and a heating, ventilating and air conditioning (HVAC) system with an airspeed of 2 m/s, inlet angle at 60° and outlet position located at the top of the back wall; (2) A workable range of temperatures (15 to 27°C) for cultivating lettuce in Los Angeles and New York City could be achieved by using a cover material of LDPE and an HVAC system with an air speed of 4m/s, inlet angle at 60° and outlet position located at the bottom of the back wall; (3) The annual energy demands of the plastic-walled MSM-VF shipping-container modular unit were far less than those for the opaque-walled control plant-factory unit in all cases, except in the one case of growing tomato in New York City. Still, in this one exception, the annual energy demand of growing tomato in New York City in the plastic-walled MSM-VF shipping-container modular unit of 557.65 kWh/m² (versus 325.34 kWh/m² for the opaque-walled control plant-factory unit) was significantly lower than that of 711.91 kWh/m², which was the average for 164 greenhouses occupying a total of 16444 m² operated by the Cornell University Agricultural Experiment Station (CUAES) in the state of New York (CUAES Greenhouses); and, (4) The annual energy demands of the plastic-walled MSM-VF shipping-container modular unit were either significantly lower or for one case approximately the same (773.84 kWh/m²) as that of the 711.91 kWh/m² for the New York greenhouses. By contrast, the annual energy demands of the opaque-walled control plant-factory unit significantly exceeded that of the 711.91 kWh/m² for the New York greenhouses by 170% for Los Angeles and by 126% for New York City, both for growing lettuce. The foregoing results provided significant and reasonable basis for the practicability of Minimally Structured & Modular Vertical Farms made of plastic-walled shipping-container modular units in Los Angeles and New York City as well as in many other mega-cities around the world with similar climates.

O trabalho tem como principais entregas: cálculo de estoques de segurança trimestrais, propostos devido a sazonalidade da demanda (apresentando os potenciais ganhos financeiros em relação ao anual) e levando em consideração as incertezas da demanda e lead time de produção, sendo o nível de serviço limitado em função da tancagem; definição da política de controle de estoques, contendo o cálculo do ponto de ressuprimento; e um comparativo entre os custos de estoque atual e teórico calculado. Além disso, como produto final, foi elaborada e entregue uma planilha de cálculos para uso exclusivo da companhia analisada para que o estoque de segurança e o ponto de ressuprimento possam ser atualizados à medida que as variáveis de entrada sofram alterações.Aiming to balance market supply and financial goals, avoiding excessive costs with inventories, this dissertation proposes a model of stock management of asphalt for the enterprise in study. The developed management model aims to enhance the current management model, which is based on employees and collaborators experience, introducing measurements and academic grounds to the enterprise practices. This assessment aims to deliver the calculation of the safety stock levels on a quarterly basis instead of an annual basis due to the seasonality of the demand (the potential gains of quarterly calculation compared to the annul calculation will also be presented) and considering the uncertainties of production demand and lead time, the level of service being limited due to the capacity to stock, the definition of the stock control policies, the calculation of the replenishment point, and a comparison between current and theoretical stock costs, including as final product, an automatic spreadsheet for the exclusive use of the analyzed company, to update the variables and calculations when necessary.

Following a departmental expansion, an isocentric cobalt-60 external beam teletheraphy unit was modified to produce a large fixed field for total body irradiation. The sourcehead was separated from the gantry and installed at a distance of 251.2 cm from the floor. The collimator was removed and replaced with a custom built secondary collimator projecting a 277 x 132.6 cm 2 radiation field at floor level. The work presented in this thesis describes the measurements performed to bring the unit into clinical use for total body irradiation. A custom flattening filter was placed below the secondary collimator to flatten the beam to within +/-3% of the central axis dose as measured at 10 cm in water. Percent depth dose, tissue-phantom-ratios, surface dose and absolute output were measured in the radiation field. The effects of inhomogeneities were studied and the thickness of lead used for lung attenuators was determined. Verification of treatment planning and delivery was performed with an Alderson-Rando anthropomorphic phantom and showed dose uniformity within +/-10% of the prescribed dose when a lead attenuator was used over the lung.

Compliance with preventive measures by health professionals is a large challenge, and it is believed that in the intensive care unit, especially those classified as neonatal and pediatric, contamination of goods, equipment, and environmental surfaces contribute significantly to the increased epidemiology of healthcare associated infections (HAIs). The objective of this study was to analyze the epidemiological and microbiological profiles of tools, equipment, and ambient surfaces contaminated with antimicrobial resistant Staphylococcus spp. in neonatal and pediatric intensive care units. It is a cross-sectional epidemiological study carried out from August 2011 to September 2012, in a neonatal and pediatric intensive care unit specializing in maternal and child health of the public health system in GoiâniaGoiás, Brazil. Samples were collected using sterile swabs moistened with saline solution 0.9%, which were subjected to microbiological processing consisting of isolation, identification and antimicrobial susceptibility testing. Analysis and interpretation of results followed. Of the 137 samples, 1 02 were identified as Staphylococcus spp. and, in six of the 12 incubators, different strains of these microorganisms were isolated, totaling 108 isolates. Among the isolates, only four were identified as Staphylococcus aureus, and the remaining 104 were coagulasenegative Staphylococcus. During the processing of isolates it was revealed that 74.5% of the tools, surfaces and equipment were infected by Staphylococcus spp., and of these, more than 80% were resistant to antimicrobials. In four, MLSB phenotype was detected. As for oxacillin-resistant isolates, 82.3 % had resistance confirmed by Etest®. Upon completion of the analysis, it became clear that the tools, surfaces and equipment used in pediatric neonatal intensive care units are reservoirs of bacteria. This immediately highlights an important contributor to the epidemiology of HAIs: compliance with procedure for the safety of infants and healthcare workers, since these findings signal gaps in the work process and therefore in the processing of these items. Therefore, it is believed that the perception of the professionals who work in health facilities (related to the risks of cross-contamination) is of unique value to understanding the need to adopt safe work practices. It is hoped, that contributing to the development of other studies, with the goal of identifying possible gaps, involving both the management of the service and standard operating procedures for the cleaning and disinfection of ambient surfaces, tools and equipment in compliance with guidelines.
A adesão às medias preventivas pelos profissionais de saúde é um amplo desafio e, acredita-se que na unidade de terapia intensiva, em especial nas de caráter neonatal e pediátrico, a contaminação de artigos, superfícies ambientais e equipamentos contribua expressivamente para o avanço da cadeia epidemiológica das Infecções Reacionadas à Assistência à Saúde (IrAS). Objetivou-se neste estudo analisar os aspectos epidemiológicos e microbiológicos de artigos, superfícies ambientais e equipamentos contaminados por Staphylococcus spp. resistentes aos antimicrobianos em unidades de terapia intensiva neonatal e pediátrica. Trata-se de um estudo epidemiológico tipo transversal desenvolvido de agosto de 2011 a setembro de 201 2, nas unidades de terapia intensiva neonatal e pediátrica de uma instituição especializada em saúde materna e infantil do Sistema Único de Saúde de Goiânia-Goiás, Brasil. Os dados foram obtidos por meio de swab, coletou-se amostras biológicas dos artigos, superfícies ambientais e equipamentos existentes nas unidades selecionadas para estudo. Realizou-se fricção bidirecional com swab estéril umedecido em solução salina a 0,9%; em seguida foi feito o processamento laboratorial dos espécimes, com isolamento, identificação e teste de suscetibilidade dos micro-organismos aos antimicrobianos; por fim, a análise e interpretação dos resultados. Das 1 37 amostras, em 1 02 foram identificados Staphylococcus spp. sendo que, em seis das 12 incubadoras foram isoladas diferentes cepas desses micro-organismos, totalizando 1 08 isolados. Dentre os isolados, apenas quatro foram identificados como Staphylococcus aureus, e os 104 restantes de Stafilococos coagulase negativo. Durante o processamento dos isolados, verificou-se que 74,5% dos artigos, superfícies e equipamentos se encontravam contaminados por Staphylococcus spp., destes mais de 80%, resistentes aos antimicrobianos testados. Mas em apenas quatro foi detectado o fenótipo resistente a macrolídeos, lincosamidas e estreptogramina B (MLSB). Quanto aos isolados resistentes à oxacilina, 82,3% tiveram a resistência confirmada pelo Epsilometer Test (Etest®). Ao concluir as análises, evidenciou-se que artigos, superfícies e equipamentos de unidades de terapia intensiva neonatal e pediátrica, são reservatórios de bactérias. Logo, representam importante papel na cadeia epidemiológica das IrAS, o que configura inconformidades com a segurança do recém nascido e do trabalhador, uma vez que, esses achados sinalizam falhas no processo de trabalho e consequentemente no processamento desses artefatos. Nessa direção, acreditase que a percepção dos profissionais que laboram em estabelecimentos de saúde relacionada aos riscos de contaminação cruzada é de singular valor para compreenderem a necessidade de adotarem atitudes seguras no ato laboral. Espera-se ainda, contribuir com o desenvolvimento de outros estudos, com o objetivo de compreender as possíveis falhas envolvendo o tanto a gestão do serviço, quanto aos processos de trabalho e de limpeza e desinfecção das superfícies ambientais, artigos e equipamentos em conformidade com as diretrizes.
