Streszczenie:

Currently, power system operation and control with AGC are undergoing fundamental changes due to rapidly increasing amount of renewable sources, energy storage system, restructuring and emerging of new types of power generation, consumption and power electronics technologies. Continuous growth in size and complexity, stochastically changing power demands, system modeling errors, alterations in electric power system structures and variations in the system parameters over the time has turned AGC task into a challenging one. Infrastructure of the intelligent power system should effectively support the provision of auxiliary services such as an AGC system from various sources through intelligent schemes. Literature survey shows that performance of AGC of interconnected power system with diverse sources gets improved by changing in controller structure, using intelligent optimization techniques for controller parameters, adding storage system and by considering different participation of diverse sources in multi area power systems. Hence, proposing and implementing new controller approaches using high performance heuristic optimization algorithms to real world problems are always welcomed. Performance of many controllers depends on proper selection of certain algorithms and specific control parameters. Hence, the goal of the present study is to propose different types of new supplementary controller to achieve better dynamic performances in multi-area with diverse source power systems, namely two area power system with and without non-linearity and three area power system with optimal and energy storage system. Based on the extensive literature review on the control designs of AGC of interconnected power system, it has been felt that new control techniques for design of AGC regulators for interconnected power system including vi renewable sources. The main objective of the proposed research work is to design new AGC regulators and develop simple, robust and easy to implement as compared with the available control techniques. The problem of nonlinearity in interconnected power system with diverse sources has also been addressed with suitable control algorithms. The presented work is divided into nine chapters. Chapter 1 deals with the introduction of AGC of power system. Widespread review of the taxonomy of optimization algorithms is presented in this chapter. Chapter 2 presents a critical review of AGC schemes in interconnected multi area power system with diverse sources. Chapter 3 stresses on the modelling of diverse sources power systems under consideration. The main simulation work starts from Chapter 4. In Chapter 4, the study is firstly conducted to propose novel Jaya based AGC of two area interconnected thermal-hydro- gas power system with varying participation of sources. In Chapter 5, novel Jaya based AI technique is further employed on realistic power system by considering non linearities like Governor Dead band (GDB), Generation Rate Constraint (GRC) and Boiler dynamics. The study is done on Jaya based AGC of two area interconnected thermal-hydro-wind and thermal-hydro-diesel power system with and without nonlinearities by considering step load and random perturbation at different control areas. In Chapter 6, designing of Optimal AGC regulator for three different three-area interconnected multi source power systems has been planned. In each power system, optimal AGC regulators have been designed by using different structures of cost weighting matrices (Q an R). vii In Chapter 7, implementation of Superconducting Magnetic Energy Storage System (SMES) in operation and control of AGC of three-area multi source power systems has been studied. Analysis of PSO tuned Integral controller for AGC of three area interconnected multi source power systems with and without SMES by considering step load perturbation at different control areas has bee done. Comparative performance of different bio-inspired artificial technique has been presented on AGC of three area interconnected power system with SMES. Chapter 8, presents AGC of three area multi source interconnected power systems by including and excluding Battery Energy Storage System (BESS) at step load perturbation in different control areas. In Chapter 9 - the performance of different control techniques presented for AGC of multi area interconnected multi source power system has been summarized and the scope of further work in this area has been highlighted.

Executive Summary - The End of the Intel Era. Today, Intel is nearly synonymous with computers. In the past thirty years nearly all personal computers and the great majority of servers have shipped with a processor based on Intel's x86 architecture, of which Intel is the dominant vendor. Yet the past few years have seen a subtle yet remarkable convergence of different industry trends that very well may topple the semiconductor giant. For the past three decades, computers have largely assumed the same shape and form, regardless of their task. Laptops, desktops, and servers have all been based on the same open modular architecture established by IBM. Yet this is not likely to be the case going forward. The past decade has seen the rise of embedded computing, perhaps best epitomized by smartphones and tablet computers. Instead of the standard PC architecture where individual components can be easily exchanged, embedded devices are typically modular designs with highly integrated physical components. Independent functional units, all designed by independent companies, are integrated onto the same piece of silicon to achieve system cost and performance targets. Instead of a standard x86 processor, each device category likely has a chip optimized for its specific application. At the same time that the form of computing is changing, we are witnessing a redistribution of where computing power resides with Cloud Computing and data centers. These have ordinarily been the province of Intel based machines, but data centers have moved from using standard off-the-shelf PCs to custom designed motherboards. Again, we are seeing a shift from the modular personal computer architecture to one that is customized for the task at hand. Another concern for Intel is that the standard metrics by which products compete are in flux. For both embedded systems and data centers, the operational costs and constraints are starting to outweigh the initial outlay costs. An example is the industry shift from overall performance to system power efficiency. Intel has been a relentless driver of processor performance, and this is a significant change of focus for its R&D divisions. Of all Intel's competitors, ARM best represents the magnitude of these challenges for Intel, and is well positioned to take advantage of all these trends. Their business model of licensing their design is well suited for a world with customized architectures, and their extensive experience in low power embedded devices has given them an advantage over Intel in processor power efficiency. Intel is heavily invested in its existing vision of the market. They have always maintained a manufacturing process advantage through tremendous investments in new foundries, and have long championed the open PC modular architecture. Time will ultimately show if Intel is capable of meeting these growing challenges. Yet it is clear that in order to do so, it must make radical changes to itself. One may ask if it is even the same company that emerges.

Nylander, Åsa. "Sensorfusion för ACC-System". Thesis, Linköping University, Department of Science and Technology, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-8341.

Streszczenie:

Genom att fusionera (sammanföra) data från olika sensorer kan ett resultat uppnås som ger mer än de enskilda sensorerna var för sig. Här utreds vilka sensorer och sensorfusionsmetoder som kan vara aktuella att använda för Scanias adaptiva farthållare (ACC). Den adaptiva farthållaren anpassar det egna fordonets hastighet inte bara till en förinställd hastighet utan även till framförvarande fordons hastighet. Scanias ACC-system använder idag en radar för måldetektering.

Det finns ett antal algoritmer och arkitekturer som passar för sensorfusionssystem beroende på nivån hos sensordatan och användningsområdet. Minstakvadratmetoder kan användas då data ska matchas mot en fysisk modell, ofta med lågnivådata. När tillgänglig data är på den nivån att den används direkt för att fatta beslut kan sannolikhetsmetoder användas. Intelligent fusion består av kognitiva modeller som avser härma den mänskliga beslutsprocessen. Till detta passar data på hög nivå.

Två lösningar, för två olika sensoruppsättningar, har tagits fram. Båda lösningarna är uppbyggda av bayesiska nätverk. Det första nätverket fusionerar data från den befintliga radarenheten med data från en kamera som detekterar vägmarkeringar. Resultaten visar att filbyten kan upptäckas tidigare i och med fusionen. Det andra nätverket använder sig av två radarenheter, den ursprungliga samt en likadan enhet till, vilket resulterar i ett bredare synfält. Nätverket avgör vilka mål hos respektive radar som kan anses vara samma matchade mål. Informationen kan användas för att öka redundansen i systemet samt för att upptäcka mål tidigare än förut.

By fusing data from different sensors a result can be achieved that is worth more than the data from each sensor by itself. Which sensors and sensor fusion methods that could be used in Scania's adaptive cruise control system (ACC) is investigated. The ACC system adapts the vehicle's speed not only to a driver decided set speed but also to the speed of preceding vehicles. Scania's ACC system uses a radar for target detection.

There exists a number of algorithms and architectures fit for use in sensor fusion systems. Which one to use depends on the level of the data to be fused and on the field of application. Least square methods are used when matching data to a physical model, data to be used is often at a low level. When working with data at decision level, probability methods are favored. Another example is intelligent fusion, cognitive methods intending to mimic the human decision process. Suitable data is data at a high level.

Two solutions, for two different sensor sets, are proposed. Both solutions are made out of Bayesian networks. The first one fuses data from the existing radar unit with data from a camera which detects lane markings. The results show that lane changes can be detected earlier thanks to the fusion. The second network uses two radar sensors of the same kind as the first, resulting in a wider field of view. The network decides which ones of each radars targets that are the same matching targets. This information could be used to increase the redundancy of the system and to detect targets earlier.

Streszczenie:

I denna rapport redogörs för en implementering av fusion mellan kortdistanssensorer. Syftet med denna implementering är att erhålla Stop & Go-funktionalitet till den adaptiva farthållaren som idag finns som tillval i Scanias lastbilar. Adaptiv farthållning, ACC, är en funktion som automatiskt anpassar fordonets hastighet ifall detta kommer ikapp ett annat fordon som färdas långsammare än den inställda hastigheten. Scanias system använder sig idag av en långdistanssensor som ser långt men har smalt synfält. Genom att komplettera denna med kortdistanssensorer, som ser kort men brett, kan önskvärt synfält i närområdet för att säkert kunna implementera Stop & Go-funktionen uppnås. Sensorfusion bygger på principen att två eller fler sensorer som ser samma sak ger en mer korrekt bild av verkligheten än en enskild. Fusionen kan genomföras på många olika sätt. I rapporten beskrivs tre metoder övergripligt; Bayesiska nätverk, auktionsalgoritmen samt Gating. I implementeringen används gatingmetoden.

Initialt implementeras en målspårningsalgoritm med kalmanfilter. Efter uppdatering av sensormjukvaran väljs dock denna bort eftersom sensorernas interna målspårning då anses som tillräcklig. En modell med sensorfusionen och målselekteringen byggs i Simulink och programmeras sedan in i en hårdvaruenhet. Syftet med detta är att kunna utvärdera funktionen i ett prototypfordon. Inledningsvis rapporteras enbart korrelerade mål från modellen. För mer kontinuerlig målföljning, främst i kurvor, implementeras därefter en algoritm som även tar hänsyn till enskilda sensorers observationer. Dessa accpeteras dock först efter en viss valideringstid eftersom denna information har lägre konfidens än korrelerade mål.

Provkörningar visar att målföljningen fungerar väl. En stor svårighet har varit att sålla bort stillastående mål från rörliga, främst i låga farter. Detta eftersom sensorernas hastighetsangivelse har låg precision vilket medför att ett stillastående mål kan rapporteras som ett långsamt rörligt.

In this thesis report an implementation of fusion between short range radars is described. The purpose of this implementation is to obtain Stop & Go functionality for the adaptive cruise control which is offered as an option in today’s Scania trucks. Adaptive cruise control, ACC, is a feature that automatically adapts the vehicle speed if it should catch up to another vehicle moving slower than the desired set speed. For this application Scania today use a long range sensor that has a long but narrow field of view. By complementing this sensor with short range sensors, which have short but wide fields of view, the desired field of view in the short range area can be obtained. This is necessary in order to be able to safely implement the Stop & Go functionality. Sensor fusion is based on the principle that two or more sensors overlooking the same area give a more accurate impression of reality than a single one. The fusion can be conducted in several ways. In the report three different methods are briefly described; Bayesian Networks, the Auction Algorithm and Gating. In the implementation the gating method is applied.

Initially a target tracking algorithm using Kalman filter is implemented. However, after software updates in the short range sensors this algorithm is no longer used. This is because the improved tracking made internally by the sensors is considered to be sufficient, hence making an external tracking algorithm redundant. The sensor fusion and the target selection are implemented in a Simulink model which is later programmed into a hardware unit. The purpose of the latter is to be able to evaluate the functionality in a prototype vehicle. Initially, only associated targets are reported from the model. In order to obtain a more continuous target tracking, mainly while driving in curves, observations made only by single sensors are also considered. However, these measurements have lower level of confidence than the associated targets. Therefore these measurements first have to be validated for a certain period of time before they are approved.

Test runs indicate that the target tracking works as intended. One major difficulty has been to separate stationary targets from slow moving ones, especially in low speeds. This is due to the fact that the sensors’ speed measurements are fairly inaccurate. Therefore a stationary target could be reported as a slow moving one.

The question about where the money goes is something really interesting for all the companies in the Internet ecosystem. While there is a huge interest, no clear answers have been provided, partially because the ecosystem keeps changing. This thesis aims to answer this question by looking at how consumers spend their money in the different parts and services associated to the Internet. Besides looking at the money that consumers spend, this research also looks at the money that is in the ecosystem in things such as online advertising, which has been seen as one of the sources of revenues for many companies. Three countries have been evaluated in this thesis, to show the situation in different parts of the world. US, UK and Spain have been the chosen countries and the comparison of the results gives a very good idea of the situation in Europe and US. A quantitative analysis has been done including six main categories: wireless, wireline voice, wireline video, wireline broadband access, ecommerce and online advertising. The results show big differences in expenditures among three different countries and analyze the potential reasons. Finally, the research also aims to identify new business opportunities for telecomm operators associated to the different categories identified in the quantitative analysis. Given the current status of the Internet ecosystem, most of the business opportunities imply the creation of partnerships with Internet companies, so these recommendations could be also applicable to Internet companies.

Streszczenie:

Innovation is fundamental to the firm and ultimately to national economic growth and stability. Systemic support for identified sectors assumes that innovation depends not only on how individual firm and non-firm actors perform but also on the dynamics of their interaction as parts of a system. To date, research within the Sectoral System of Innovation framework perceived fit as a function of enablement between the firm and the system based on industry type. This is problematic as assuming firms are homogenous overlooks the impact of critical micro level contingencies such as age and strategic intent in achieving fit, and in turn enabling innovation. Consistent with theory that organisational performance is a function of the fit between two or more factors within a system, this thesis departs from previous macro and meso system-level approaches by undertaking a micro level analysis of how fit is mediated by age and strategy contingencies in two contrasting sectors. Using interview and survey data of Irish software and manufacturing engineering companies, this represents the first empirical analysis of contingency-based system fit. This study reveals a detachment between the universality implied in the design of Sectoral Systems of Innovation and the heterogeneity of firm context. Importantly, this finding provides strong evidence supporting previously intuitive calls for policy makers to place greater emphasis on firm dynamics. The findings in relation to firm age and strategic intent demonstrate that the nature of value creation hinges significantly on firm-level contingencies. This new departure extends current thinking on Systems of Innovation by clearly demonstrating the effects of firm-level characteristics, adding to the explanatory breadth of the existing framework. This contribution to theory has important implications for both firm managers and policy makers, enabling more effective interventions in their efforts to drive and support innovation outcomes.

Streszczenie:

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer. The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result. Relevant literature has been collected through scientific articles, books. In order to find relevant information, a flow mapping on Billet preparation of Sandvik AB was performed. The information was summarized in a situation analysis. In order to design the AGV system, we found that analytical approach and simulation was according to the literature's most successful approaches. By using these methods in the theoretical model and adjust their performance against one another the results from the model should be a sufficiently accurate reflection of the design needed to serve the Billet preparation.

ABC Analysis is an inventory categorization technique used to classify and prioritize inventory items in an effort to better allocate business resources. A items are defined as the inventory items considered extremely important to the business, requiring strict oversight and control. B items are important to the business, but don’t require the tight controls and oversight required of the A items. C items are marginally important to the business. ABC Analysis aims to ensure the business-driving inventory items are effectively and efficiently managed. There are numerous single- and multiple-criteria approaches to implementing ABC Analysis. This thesis presents an analysis and comparison of multiple approaches, as they relate to Navy Weapons Systems Support (WSS) Command’s large National Item Identification Number (NIIN) inventory. Additionally, random forests are grown from the inventory metadata to identify and/or verify the attributes most strongly affecting fleet readiness goals. The model will allow WSS to focus resources not only on the correct NIINs, but in the correct areas of NIIN management. Better WSS resource allocation will result in higher fleet readiness, WSS’s primary goal.

Streszczenie:

In this thesis, we study the population dynamics of predator-prey interactions described by mathematical models with age/stage structures. We first consider fixed development times for predators and prey and develop a stage-structured predator-prey model with Holling type II functional response. The analysis shows that the threshold dynamics holds. That is, the predator-extinction equilibrium is globally stable if the net reproductive number of the predator $\mathcal{R}_0$ is less than $1$, while the predator population persists if $\mathcal{R}_0$ is greater than $1$. Numerical simulations are carried out to demonstrate and extend our theoretical results. A general maturation function for predators is then assumed, and an age-structured predator-prey model with no age structure for prey is formulated. Conditions for the existence and local stabilities of equilibria are obtained. The global stability of the predator-extinction equilibrium is proved by constructing a Lyapunov functional. Finally, we consider a special case of the maturation function discussed before. More specifically, we assume that the development times of predators follow a shifted Gamma distribution and then transfer the previous model into a system of differential-integral equations. We consider the existence and local stabilities of equilibria. Conditions for existence of Hopf bifurcation are given when the shape parameters of Gamma distributions are $1$ and $2$.

The publications submitted for this PhD by Published Work represent the product of a decade long programme of research on the nature of the defence innovation system and the organisations, institutions and relationships that underpin defence technological innovation. This has been informed by the systems of innovation approach as well as broader academic perspectives on the nature of innovation and as such the publications are located in the field of innovation studies and in particular the sub-community of scholars that concern themselves with defence technological innovation. In the thesis, I contend that – taken together – the publications make three contributions to knowledge. First, the publications contribute to our understanding of what I term the “defence innovation system”. This illuminates an important corner ignored by most scholars of innovation systems and one that has received too little attention given the role that defence R&D and procurement has played as a stimulus to many significant technological innovations as well as its many implications for international security and society. The defence innovation system has often resisted analysis not least because of the limitations of publicly available information. My publications show recognition of the importance of this topic and shed light on the dynamics of defence technological innovation. Second, the publications contribute to our understanding of the organisations and relationships that underpin the defence innovation system and their response to changes in their operating environment since the end of the Cold War. My focus on organisation-level case studies of defence firms and government defence research establishments is in contrast to most of the academic work in this field that has been preoccupied with national or industry level structure and trends. A recurring theme in my publications, explicitly and implicitly, has been the co-evolutionary character of change in the defence innovation system and the changing relationship between government and defence industrial firms. Third, I examine changes in the boundaries of the system by introducing a transnational dimension to the analysis of defence technological innovation and in doing so my publications have drawn attention to the need to examine transnational linkages between nationally-located systems.

Streszczenie:

Heat-integrated crude oil distillation systems – the atmospheric and vacuum distillation towers and associated heat recovery system – are energy and capital intensive. The structures of the distillation columns are very complex and the distillation columns interact strongly with the preheat train. There are many degrees of freedom in this system, most of which are interlinked with each other and cannot be considered separately. A systematic design approach is necessary to exploit these design issues for increasing the efficiency with which energy and capital are employed in the overall system. This thesis develops an optimisation-based methodology for the simultaneous design of crude oil distillation systems. Both new design and retrofit scenarios are considered. This design approach considers some significant design issues and generates design solutions that are realisable and industrially practicable. Robust and more accurate models have been developed to represent the distillation columns and heat exchanger networks (HENs) within an optimisation framework, compared with previous work. Facilitated by the decomposition approach (Liebmann, 1996), simplified models (Suphanit, 1999; Gadalla et al., 2003a; Rastogi, 2006), based on the Fenske-Underwood-Gilliland method, were developed previously to model the atmospheric distillation unit and the vacuum unit. This work extends and modifies these simplified models to account more accurately for the effect of pump-around location on the separation performance in atmospheric units. Moreover, the simplified model has been extended to consider an atmospheric distillation column with a pump-around located above the top side-stripper. This work also proposes a new methodology to incorporate product specifications following refining conventional in the simplified models. The proposed approach enables systematic identification of key components and associated recoveries to match specified boiling temperature profiles, as these are normally used as indicators of separation performance in the refining industry. The new simplified models are validated by comparison with rigorous simulation results of atmospheric distillation columns. Multi-segmented stream data are implemented in the design and analysis of heat exchanger networks, in which the thermal properties of streams are temperature dependent and cannot be assumed constant. Two existing promising HEN design approaches, the simulated annealing optimisation-based approach (Rodriguez, 2005)and the network pinch approach (Asante and Zhu, 1996), are modified and extended to apply to the HEN design with multi-segmented stream data. In the modified network pinch approach, the bottleneck of an existing HEN configuration is better overcome by varying stream split fractions and heat exchanger loads at the same time, rather than simply redistributing heat loads. The modified network pinch approach also combines structural modifications and cost optimisation in a single step to avoid missing cost-effective design solutions. An optimisation framework, applying a stochastic optimisation method – multiple simulated annealing runs – is developed to generate grassroots and retrofit designs of the heat-integrated crude oil distillation systems. The heat integration of the system is accounted for more accurately than previously by using multi-segmented stream data. Operating conditions and pump-around locations of distillation columns are optimised, together with structural options and continuous variables of heat exchanger networks as appropriate, in a single optimisation framework. The new degrees of freedom considered in this work include key components and associated recoveries (used in simplified models of distillation columns to express the separation of products) and operating pressures of distillation columns. The optimisation of key components and recoveries allow the systematic exploitation of product distributions and product slate in order to maximise net profit. Including operating pressures in the optimisation facilitates creation of heat recovery opportunities in configuration studies. Product specification constraints are imposed in the optimisation so that product quality is not compromised during design. A novel distillation configuration, with a liquid side-draw prefractionator column upstream of an atmospheric distillation column, is proposed in this work. The case study shows a very promising performance with respect to energy efficiency. Case studies illustrate the beneficial application of the proposed approach in both grassroots and retrofit design of crude oil distillation systems, with respect to energy demand and net profit improvement. Comparisons are made between different configurations, and results are given as proof of principle.

Streszczenie:

Autonomous systems have progressed from theory to application especially in the last decade, thanks to the recent technological evolution. The number of autonomous systems in our surroundings is increasing rapidly. Since these systems in most cases handle privacy-sensitive data, the privacy concerns are also increasing at a similar rate. However, privacy research has not been in sync with these developments. Moreover, the systems are heterogeneous in nature and continuously evolving which makes the privacy problem even more challenging. The domain poses some unique privacy challenges which are not always possible to solve using existing solutions from other related fields. In this thesis, we identify open privacy challenges of autonomous systems and later propose solutions to some of the most prominent challenges. We investigate the privacy challenges in the context of smart home-based systems including Ambient Assisted Living (AAL) systems as well as autonomous vehicles. In the case of smart home, we propose a framework to enhance the privacy of owners during ownership change of IoT devices and conduct a systematic literature review to identify the privacy challenges of home-based health monitoring systems. For autonomous vehicles, we quantify, improve, and tune the privacy utility trade-off of the image de-identification process. Our investigation reveals that there is a lack of consideration when it comes to the privacy of autonomous systems and there are several open research questions in the domain regarding, for instance, privacy-preserving data management, quantification of privacy utility trade-off, and compliance with privacy laws. Since the field is evolving, this work can be seen as a step towards privacy preserving autonomous systems. The identified privacy concerns and their corresponding solutions presented in this thesis will help the research community to identify and address existing privacy concerns of autonomous systems. Solving the concerns will encourage the end-users to adopt the systems and enjoy the benefits without bothering about privacy.

Streszczenie:

Weakness and fatigue in the human triceps surae have been assessed objectively by the measurement of absolute force evoked using supramaximal stimulation. The effects of disuse, age and exercise were systematically investigated. Under control conditions the triceps surae of young men were found to generate high maximal tetanic forces, have a mean twitch time to peak tension of 107 msec and did not fatigue readily. This was indicative of a large muscle mass with a predominance of type I (slow twitch) fibres. Muscle temperature manipulation over the range 29.5 to 39.1°C did not affect maximal force generation but had a profound effect on the force and time course of twitch and unfused tetanic responses. The triceps surae of 70 year old men were found to be slower contracting weaker and yet, paradoxically more fatiguable than, those of young men. These changes may be explained by a slowing of the Ca 2+ kinetics in the remaining muscle fibres of the elderly and restricted blood supply during intermittent exercise. Long term immobilisation due to injury caused a substantial reduction in the force generating capacity of the triceps surae and a change in twitch time course which could be explained by selective type I fibre atropy. In contrast voluntary immobilisation for 2 weeks caused a reduction of maximal voluntary force and a prolongation of the twitch response which could not be accounted for by loss of contractile machinery. Voluntary dynamic exercise involving concentric contraction of the triceps surae produced small short lasting force decrements. Eccentric contractions caused large long lasting decreases in force particularly at low stimulus frequencies, which were explained by uncoupling of excitation and contraction. Responses to submaximal stimulation were found to be voltage dependent and did not accurately reflect the response of the whole muscle. The need for supramaximal stimulation in the assessment of weakness and fatigue in the human triceps surae was highlighted.

This thesis explores the ever-current topic of pensions, which are devoted to three different chapters . The first part descriptes history development of old-age pensions, focusing on developments in the last more than 200 years. Emphasis is placed on the development of the territory of the present Czech Republic and for each period are also enclosed a historici fact that not only the development of the pension system determined . Another chapter is devoted to an over view of different types of pension system. Together with a description of each pillar by the World Bank definition are also accompanied by examples of systems from different European countries. The last and most extensive part of the work is to point out the existing demographic development of the czech population, finding appropriate indicators applicable to the issue of pensions, to find the possible future evolution of these indicators using statistical and demographic methods and last but not least the program provides potential candidates for the calculation of future retirement or the age at which a person is able to retire . The work will provide readers with comprehensive information not only on the current state pension insurance in the Czech Republic and in Europe but also can learn about the reasons that led to the establishment of what is possible developments, together with suggestions.

Streszczenie:

The studies presented in this thesis aimed to investigate the effects of nutritional modulation and age-associated changes on insulin sensitivity. Four separate studies were performed; three of these had insulin sensitivity as the primary outcome. Existing studies show that ageing is associated with insulin resistance, but data may be confounded by several factors that also occur with increasing age, such as increased adiposity, skeletal muscle lipid accumulation and reduced physical activity. To elucidate this further the first study compared body composition, skeletal muscle lipid content, fat metabolism during light-intensity exercise and whole-body and skeletal muscle insulin sensitivity between 7 healthy young and 14 older males. Ageing and insulin resistance are also associated with impaired skeletal muscle protein synthesis, however the effects of insulin resistance per se on amino acid metabolism and associated insulin signalling pathways are not really known. The second study involved 8 young healthy males and aimed to explore the effect of insulin resistance on the protein synthetic response to amino acid ingestion and muscle protein signalling pathway in humans. Dietary intake has been shown to affect insulin sensitivity; however it is unclear if diet composition affects liver fat content independent of energy balance. Therefore the third study aimed to investigate the effects of hyperenergetic diets high in fat or carbohydrate on liver fat and insulin sensitivity. The study involved 23 healthy but overweight and obese males who initially consumed an isoenergetic diet for one week, and then were randomised to 2 weeks of either hyperenergetic (+25% excess) high fat or high carbohydrate diets. Liver fat content, abdominal visceral fat, skeletal muscle fat content, hepatic lipid metabolism and insulin sensitivity were assessed before and after the 2 week intervention period. Whilst dietary excess can exacerbate insulin resistance, certain micronutrients may improve insulin sensitivity. Carnitine has shown encouraging outcomes in relation to promoting fatty acid oxidation, metabolism and modulating body composition in healthy young volunteers. However the effects on older people have never been explored. This formed the basis of the fourth study that investigated the effects of 6 months of oral carnitine supplementation or placebo in 14 older (≥65 years of age) healthy males in relation to fatty acid metabolism, skeletal muscle lipid and insulin sensitivity. The main findings are summarised. Irrespective of age, adiposity and physical activity are associated with impaired fatty acid oxidation, greater skeletal muscle lipid accumulation and reduced insulin sensitivity. However ageing per se appears to increase the sympathetic response to exercise and enhance systemic fatty acid delivery and adipose tissue lipolysis. Insulin resistance induced by acute elevation of lipid was found to affect the skeletal muscle protein synthetic response to amino acid ingestion, and this impairment appeared to occur downstream from the Akt insulin signalling pathway. Energy excess per se increases liver fat content and affects liver metabolism but there were no differential effects of carbohydrate or fat on hepatic insulin sensitivity and liver fat content. Finally, oral carnitine ingestion for 6 months successfully increased skeletal muscle total carnitine content of older healthy people and resulted in increased fatty acid oxidation and intramyocellular lipid (IMCL) utilisation during light-intensity exercise, but no effect on skeletal muscle insulin sensitivity was seen. These studies have increased mechanistic insight into the associations between ageing, nutrients and insulin sensitivity, paving the way to further research.

The military is the midst of significant change, due to the DoD transformation guidance and movement to Network-Centric Warfare/Operations. Unfortunately, both the guidance given, roadmaps produced and the level of espoused support for the transformation have caused fundamental change to occur slowly and at increasing expense. The military material development process was designed around a platform-centric system and worked well, but now the information age is causing a move to network-centric systems. This fundamental shift is not aligned with the DoD development process and reform will require broad changes in both organization and policy. This paper reviews the NCW Transformation goal, the DoD transformation guidance and compares them to the Transformation Roadmaps of the Army, Navy and Air Force. These guidance documents are then compared with actual transformation changes and the associated factors effecting the change, using J. Forrester type system dynamics models. The systems dynamics analysis studies numerous transformation factors for their effects and yields recommended alternative development architecture.
(cont.) The goal of the paper is to align the DoD development process with the transformation guidance goals to result in a process which speeds prototype testing, development and fielding of new military systems, while integrating state-of-the-art business practice and theory. This resulted in the creation of several models which describe the various acquisition systems and a new model which addresses the issues found in the other models. The new model represents a reconfigured architecture for the DoD acquisitions system and a new organization to implement the transformation.

This thesis provides the rationale for the necessity of a redefining of the holistic back into nursing after the consequences of technological restructuring. This study revealed that the impact of modern technology-based, prescriptive changes on professional nursing practice in Canada has resulted in an increasing alienation of labour for nurses, including direct interference with patient-based nursing care, authority, necessity for broader knowledge systems, stability and fragility in job security. The implications of this examination have demonstrated that this shift has not been the result of mechanical technologies alone, but the science-based management philosophies and communicative nature of technologies as well.
This project has verified that more importantly than the advancing technological shift itself the danger for professional nursing has been in what these systems are actively replacing. Namely, prescriptive technologies work to establish a managerial or 'expert' presence and authority within the practice of nursing serving to change professional understandings for nurses as well as to decrease value in the judgement and holistic care skills of registered nurses.

Streszczenie:

Come molti altri settori produttivi, anche l'agricoltura deve affrontare una crescente dipendenza energetica da elettricità, petrolio e gas naturale. Tuttavia, l'agricoltura può rispondere direttamente a tali richieste ricorrendo alle fonti di energia rinnovabili (FER), come il solare fotovoltaico (PV) e gli impianti biogas/biometano (BP). Questi sistemi sono stati fortemente incentivati in passato. Gli attuali sistemi d’incentivazione prevedono invece sussidi commisurati alle caratteristiche aziendali come stalle, fienili, disponibilità di biomasse, ecc. Per questi motivi, per quanto riguarda il settore FV, è necessario utilizzare modelli analitici affidabili per valutare l’orientamento e la tecnologia migliore, in particolare per generatori integrati architettonicamente. Per la produzione di biometano, gli impianti di piccole dimensioni risultano quelli maggiormente incentivati previa alimentazione con sottoprodotti agro-industriali. Tuttavia, le loro performance dipendono fortemente dalla tecnologia d’upgrading. Pertanto, le prospettive economiche offerte da questi sistemi RES sono legate alla scelta della tecnologia da impiegare e non più esclusivamente al semplice dimensionamento. Su questa base, l'obiettivo principale di questo lavoro è stato lo sviluppo di strumenti di supporto decisionali (DSSS) per l'ottimizzazione energetica d’impianti FV e BP. Un primo studio si è focalizzato sull’analisi prestazionale per singolo componente e globale d’impianti FV installati in un’azienda agricola. Inoltre, una procedura analitica di ottimizzazione dei parametri d’impianto è stata definita per massimizzare il rendimento elettrico di un generatore integrato architettonicamente rispetto ad un’installazione a terra. Attraverso una serie d’informazioni tecnico-economiche di tecnologie di upgrading, un secondo studio è stato condotto con l'obiettivo di sviluppare un DSS per valutare la marginalità sul reddito aziendale data dall’installazione on-farm di un impianto BP collegato alla rete del gas naturale. I risultati dei due studi hanno dimostrato come questi DSS possono essere utili strumenti per valutare preventivamente le diverse potenzialità offerte da impianti FV e BP in base alle caratteristiche di un’azienda agricola.
Like many other productive sectors, even agriculture must tackle an increasing energy dependency on electricity, petroleum and natural gas. Nevertheless, agriculture can directly respond to such request thanks to renewable energy systems (RES) like solar photovoltaic (PV) and biogas/biomethane (BP) plants. These systems have been strongly incentivized in the past. On the contrary, current incentive schemes provide feed-in-tariffs proportionate to farming characteristics as stables, barns, biomass availability, etc. For this reason, as regards the PV sector, it is required to use reliable analytical models for assessing the best orientation and technology, in particular for architecturally integrated generators. For the biomethane production, small-medium plants have stronger incentives in particular using agro-food by-products as feed. However, their performances are strongly dependent on biomethane upgrading technology. Thus, the economic prospective offered by these RES systems are substantially tied to technology choice optimization and no longer solely in simple sizing. On this basis, the main goal of this work is to develop Decision Support Tools (DSSs) for energy optimization both for PV and BP plants. A first study was focused on the analysis of PV plants installed in the same farm. The aim is to examine the impact each plant component has on the PV generator global efficiency and define an analytical procedure for technical parameters optimization in order to maximize the electric yield of an architectonically integrated plant compared to a ground-mounted one. Based on the economic and efficiency features of a biomethane upgrading technology set, a second study was carried out with the aim to design a DSS to assess enterprise-wide profit margins resulting from the on-farm BP plant installation linked to the natural gas grid. The results of the two studies have shown how these DSSs can be useful tools for choosing PV and BP technologies based on farm characteristics.

Streszczenie:

Over 300,000 individuals are injured every year by vehicle related accidents in the United Kingdom alone. Government and the vehicle manufacturers are not only bringing new legislation but are also investing in vehicle safety research to bring this figure down. A private self-driven car is an important factor in maintaining the independence and quality of life of the third age individuals. However, since older people brings deterioration of cognitive, physical and visual abilities, resulting in slower reaction times and lapses while driving. The third age individuals are involved in more vehicle related accidents than middle aged individuals. This scenario is corrected by the fact that the number of third age individuals is increasing, especially in developed countries. It is expected that the percentage of third age individuals in the United Kingdom will increase to 20% of the total population by 2010. Several safety systems have been developed by the automotive industry including intelligent airbags, Electronic Stability Control (ESC) and pre-tensioned seat belts, but nothing has been specifically developed for the third age related problems. This thesis proposes a driver posture identification system using low resolution infrared imaging. The use of a low resolution thermal imager provides a reliable non-contact based posture identification system at a relatively low cost and is shown to provide robust performance over a wide range of conditions. The low resolution also protects the privacy of the driver. In order to develop the proposed safety system an Artificial Intelligent Thermal Imaging algorithm (AITl) is created in MatLAB. Experimentation is conducted in real and simulated environment, with human subjects, to evaluate the results of the algorithm. The result shows that the safety system is able to identify eighteen different driving postures. The system also provides other valuable information about the driver such as driver physical built, fatigue, smoking, mobile phone usage, eye-height and trunk stability. It is clear that in incorporating this safety system in the overall automotive central strategy, better safety for third age individual can be achieved. This thesis provides various contributions to knowledge including a novel neural network design, a safety system using low resolution infrared imager and an algorithm that can identify driver posture.

Lo scopo principale di questa tesi è stato quello di indagare se gli effetti di: (i) razza (Bergamasca, Merinizzata Italiana e Sopravvissana); (ii) età di macellazione (40 vs 60 giorni) e (iii) stagione di allevamento (inverno vs autunno) abbiano influenzato le performance di allevamento, macellazione, qualità della carne e composizione di Acidi Grassi (FA) degli agnelli leggeri a marchio “Agnello del Centro Italia” IGP, allevati con sistema transumante nella regione Marche (Italia centrale). Gli agnelli delle razze oggetto di studio hanno mostrato performance di crescita, resa in carcassa e qualità della carne (es. caratteristiche fisiche e chimiche) simili, nonostante si siano evidenziate differenze in alcuni parametri (peso spalle, % proteina, cooking loss, TBARS e ORAC). L'effetto razza ha influenzato significativamente il profilo acidico della carne e del tessuto adiposo ed alcuni parametri legati al valore nutrizionale della carne (PUFA/SFA e indice trombogenico). Lo studio condotto per valutare l’effetto età di macellazione nella razza Bergamasca ha influenzato le caratteristiche quanti -qualitative della carcassa e della carne (drip loss, colore) e anche la composizione acidica del grasso. Considerando sempre la razza Bergamasca, l’effetto stagione di macellazione ha influenzato le caratteristiche della carcassa (corata) e della carne (pH e drip loss a 6 d), come anche il profilo FA della carne e del tessuto adiposo. Questo studio fornisce pertanto ulteriori informazioni sulla qualità di carcassa e carni di agnelli leggeri IGP “Agnello del centro Italia” ottenuti da razze differenti, allevati in stagioni diverse e macellati a differenti età e prodotti con sistema transumante nella regione Marche.
The main aim of the thesis was to investigate the effects of (i) breed (Bergamasca, Italian Merino and Sopravissana), (ii) slaughter age (40 vs. 60 days) and (iii) rearing season (winter vs. autumn) on growth, slaughter traits and meat quality, including fatty acid (FA) composition of “Agnello del Centro Italia” PGI light lambs produced under traditional transhumant sheep system adopted in Marche region (Central Italy). The lambs of the studied breeds showed similar growth performances, carcass traits and meat quality (i.e., physical and chemical characteristics), despite some differences in the investigated parameters that occurred (e.g. % crude protein, cooking loss, TBARS and ORAC). Breed significantly affected FA profile of meat and adipose tissue with Bergamasca showing less favourable meat FA profile (the lowest values of conjugated linoleic acid and the highest thrombogenic index). Higher slaughter age in Bergamasca lambs improved some carcass traits and physical characteristics of meat, it did not influence meat chemical composition or strongly affect meat FA profile, but it worsened chemical composition of adipose tissue. These results suggest 60 days as the optimal slaughter age for Bergamasca to produce slightly heavier carcasses without compromising the quality of lamb meat. Different rearing seasons influenced carcass traits (pluck) and meat quality (pH and drip loss after 6 days of meat storage). FA profile of both meat and adipose tissue was influenced by the rearing season with lambs reared in autumn having adipose tissue with better FA profile for human health. The research provides additional information filling the present gaps of knowledge regarding the quality of “Agnello del Centro Italia” light lambs produced under traditional systems in Marche region for local breeders and consumers.

Streszczenie:

Scania är ett företag verksamt inom fordonsindustrin och är en tillverkare av lastbilar, bussar och motorer. Fordonsindustrin står inför en förändring och Scania vill vara drivande i utvecklingen. För att kunna vara det ställs krav på flexibilitet i produktionen och i denna studie har Scanias bakaxelmontering undersökts. I dagsläget används gaffeltruckar i stor utsträckning för att transportera artiklar mellan lager, plockområde och produktionslina, vilket begränsar utformningen av plockområdet. En introduktion av Automated Guided Vehicles (AGV) möjliggör en mer flexibel utformning. Studien syftar till att utvärdera AGV:er som transportelement för lastbärare. För att göra det undersöks det hur tre olika typer av AGV:er påverkar tiden med artikelbrist vid produktionslinan relativt antal som används samt hur dessa utnyttjas. Vidare undersöks det hur olika egenskaper i ett AGV-system påverkar kötiden för transporter. Egenskaperna som undersöks är AGV:ernas hastighet, av- och pålastningstid, laddningstid och batteritid. Systemet som undersöks i studien är en del av ett produktionsområde efter en planerad ombyggnation och inga jämförelser kommer göras med systemet innan ombyggnation. En simuleringsmodell har tagits fram i ExtendSim och genom den har experiment utförts för att besvara syftet. I studien har två olika typer av experiment utförts, dels experiment där antalet AGV:er var den experimentella faktorn, dels experiment enligt faktordesign där AGV-systemets egenskaper var de experimentella faktorerna. Resultaten från experimenten visar att när antalet AGV:er ökar till en viss gräns, minskar tiden med brist vid produktionslinan och funktionen för dynamisk laddning kan utnyttjas i högre grad. Utöver detta visar resultatet från experimenten enligt faktordesign att batteritid är den enskilt viktigaste egenskapen enligt de förutsättningar experimenten utfördes under. Därefter var AGV:ernas genomsnittliga hastighet den viktigaste egenskapen följt av laddningstid och av- och pålastningstid. Slutsatsen är att när antalet AGV:er ökar, minskar tiden med brist för upp till sex AGV:er av typ 1 och typ 2 samt åtta AGV:er av typ 3. Utnyttjandegraden visar att när fler AGV:er används kan funktionen för dynamisk laddning utnyttjas i högre grad, vilket gör att de är tillgängliga i större utsträckning när transportbehov uppstår. Det har också visats att antalet AGV:er som används i systemet bör vara tillräckligt för att de aldrig ska underskrida den kritiska batterinivån. Jämförelser av den totala tiden med brist vid produktionslinan mellan olika typer av AGV:er visade att typ 1 var bättre än typ 3 när lika antal AGV:er användes. Mellan typ 2 och typ 3 kunde ingen skillnad påvisas när fler än fem AGV:er användes. När fem eller färre AGV:er användes var typ 3 bättre än typ 2. En jämförelse mellan typ 1 och typ 2 visade att typ 1 var bättre när upp till fem AGV:er användes, men att det för sex AGV:er inte gick att avgöra någon skillnad.

Industries such as trade, manufacturing and transportation have undergone significant changes due to the globalization concept. Sea ports play a very important role in building and strengthening the economies of countries worldwide. Due to the high rate of production, the work load has increased at the ports which resulted into financial as well as capacity problems. As a result of such problems, cost optimized and automated solutions are being developed and introduced at the ports. In the horizontal transport system of the sea ports, AGVs are one of those automated solutions used to transport containers from ships to yard and vice versa. Newer and more practices are being employed to make the efficient transportation of these AGVs. Numexia has recently introduced a new version of Cassette AGVs called Zero-Emission C-AGV. A conceptual model is developed for Zero-Emission C-AGVs and different layouts are evaluated using multi agent-based simulation. The greedy algorithm has been used for the efficient dispatching of jobs. The Simulation will carry out the dispatching of jobs for C-AGVs between quay area and yard using different layouts and scenarios for the unloading operation.

The thesis examines the notion that an age of terrorism began In the late 1960s. It Is argued that this Issue is complicated by the different meanings associated with the term, terrorism. Three main meanings of the term are identified: a normative usage treating terrorism as violence without humanitarian constraints; its association with the lowest level of violent conflict; and a usage that treats terrorism as in practice co-terminus with assaults on the west. An examination of the most common generalisations about terrorism to be found in the literature follows. The use of the term In different contexts is highlighted by case studies of West Germany and Northern Ireland. It is argued that in so far as it is possible to treat the varieties of modern terrorisms as one, they are best seen as a post-colonial phenomenon which drew on the legitimisation of anti-imperialist violence against colonial rule. The reluctance to apply the term, terrorism, to political violence inside Third World countries is considered. The centrality of an international dimension to terrorism is analysed, followed by an examination of International co-operation to control covert violence by small groups that crosses state boundaries. Case studies of the ending of campaigns of violence by small groups are presented to underline the role played by internal group dynamics in terrorism. In conclusion, it is argued that the term, terrorism, is losing its coherence and, partly for that reason, terrorism is unlikely to be seen as a central feature of the international political system in the post-bipolar era.

A transactive memory system (TMS) is a means by which people may store information externally; in such a system the task of remembering is offloaded by remembering where information is located, rather than remembering the information itself. As Sparrow et al. (2011) suggest in the article Google Effects on Memory: Cognitive Consequences of Having Information at Our Fingertips, people are beginning to use the internet and computers as a TMS, and this use is changing the way people encounter and treat information. The purpose of this thesis is to investigate whether preference for TMS type (either with books or with computers) varies across age groups. An interaction between TMS preference and age was hypothesized. Before the onset of the internet age, information was primarily found in books and other print materials whereas now the internet is more frequently used, thus this shift in thinking and habit across generations was expected to emerge in the data. The study yielded a total of 51 participants, 32 from the young age group (ages 18-24) and 19 from the old (ages 61-81). A modified Stroop task and question blocks (for priming purposes) were employed to examine whether people are prone to think of book- or computer-related sources when in search of information. Also, a "Look up or Learn" tendencies survey was used to better understand how people decide whether certain information should be learned or left to be "looked up" later (Yacci & Rosanski, 2012). The mixed ANOVA did not reveal main effects for question difficulty or TMS type, nor was an interaction with age found. The results were not consistent with those of Sparrow et al. (2011) and did not show significance for TMS preference. Future studies should continue to examine the Google effect and TMS preference, as it bears important applications for a number of fields.
