This item is printed on demand - it takes 3-4 days longer - Neuware -Corrosion of reinforced concrete (RC) structure becomes severe problem worldwide and results in a need of a huge budget for the maintenance of the corroded structure. In spite of this need, the concept of repair design and execution is still not well established. Without correct understanding how repair work changes behaviors of the RC structure, the repair work become risky as can been seen from many early failures of repaired RC members. The traditional structural analysis seems to be irrelevant to the repaired structure. This book illustrates how the structural behaviors of the flexural RC members are degraded by corrosion and changed by patching repair. The clear example is given through a sound experimental investigation. The numerical analysis was conducted to reproduce the structural performance of repaired RC. The bonding characteristic between repair materials and base concrete is represented by basic Coulomb friction model. The methodology provided in this book should be beneficial especially to professionals in the repair of RC structure or anyone else who may be dealing with the corrosion problem of RC structure. 108 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -With the rapid growth of data and computational needs, distributed systems and computational Grids are gaining more and more attention. Grids are playing an important and growing role in today networks. The huge amount of computations a Grid can fulfill in a specific time cannot be done by the best super computers. However, Grid performance can still be improved by making sure all the resources available in the Grid are utilized by a good load balancing algorithm. The purpose of such algorithms is to make sure all nodes are equally involved in Grid computations. This research proposes two new distributed swarm intelligence inspired load balancing algorithms. One is based on ant colony optimization and is called AntZ, the other one is based on particle swarm optimization and is called ParticleZ. 104 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Pharmacist-physician collaboration has been shown toimprove the safety and cost-effectiveness of drug therapy,however, it occurs relatively infrequently in the community setting,with respect to drug therapy management. This book provides information regarding family physician attitudes towards andreadiness to collaborate with community pharmacists on drugtherapy management. We developed a survey instrumentutilizing the Transtheoretical Model of Behaviour Change, andadministered it to a random sample of 848 family physicians in Ontario,Canada. We found that collaborative relationships betweenpharmacists and physicians were generally underdeveloped.System-related barriers, including pharmacists' lack of patient information,were highlighted by physicians as particularly problematic forcollaborative relationship development. Our analysis sheds light onthe predictors of physician readiness to collaborate withpharmacists, and provide direction for policy makers and health professionalsinterested in developing collaborative working relationship withphysicians. 112 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Buildings typically hide a large and cost-effectivepotential for saving carbon dioxide through energyefficiency improvements. However, numerous barriersmake the opportunities for energy saving in buildingsdifficult to capture. The project-based mechanisms ofthe Kyoto Protocol do not seem to adequately coverenergy efficiency activities in the building sector.Green Investment Schemes (GIS) as an innovativeinstrument offer promising solutions but the mainquestion is how they could be practically designedfor this purpose.The work examines the applicability of GIS withrespect to energy efficiency projects in buildings.First, it looks at the prospects of GIS as a policymitigation instrument in Bulgaria and identifies theexisting barriers to energy efficiency in theBulgarian building sector. Then it discusses thepossibilities for GIS to cover energy efficiencyactivities in buildings, and particularly how certainelements of GIS can overcome the specific barriers toenergy efficiency in this sector. The book concludeswith recommendations for possible GIS design options.It should be especially useful to professionals inclimate change and energy efficiency fields. 80 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It has long been known that somatic illness in a parent is a risk factor for later psychiatric disorders in children, and despite this, little attention has been paid to children's mental health. Children reactions being exposed to an ill parent suffering for acute central nervous system injury are insufficiently known, studies being almost nonexistent. This book, therefore, provides an in-depth analysis of data concerning types and frequencies of mental health problems in children, and aims to specify interaction modalities of specific risks and protective factors, to evaluate attitudes toward preventive intervention, as well as to evaluate an innovative family counselling intervention in an experimental controlled trial. The results suggest a number of interventions which may reduce the negative effects of parental acute central nervous system injury on a child. Thus, interventions aimed at enhancing affective responsiveness, involvement and communication in the family could be helpful. Specifically interventions aimed at helping parents to cope with the situation and to decrease individual parental depressive symptoms may work to help children with their psychosocial outcome. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The issue of Foreign Direct Investment has elicited international attention in recent times, mainly because of the growing awareness of the economic explioitation of millions of Africans. Some of the Leaders of the African continent, along with their governments, have equally placed the lack of FDI high on their agendas. This awareness has generated sustained debates within governments, international organisations and the private sector, to try and formulate policies aimed at addressing the problem regarding the lack of FDI. FDI has a clear and distinct effect on Africa and its economies; it therefore should be seen as the most positive approach that should be followed to address the problems listed below. The dominant debates around Africa are those concerning poverty alleviation, sustainable development, infrastucture development and economic stability. The lack of a collaborative approach within Africa with reference to economic integration, and the effects FDI has with specific reference to investment flows and the role of rating agencies, places Africa in a negative position. 108 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Zimbabwe is a republic without a homegrown democratic constitution.The absence of a people's constitution that dictates a democratic electoral framework, formation of legitimate government, observance of human rights, and good governance has led to the country's deepening crises of political dictatorship, violent electoral conflicts,state violence against citizens,economic collapse, financial corruption, social disintegration,and international isolation.These tragedies have left the country without a currency of its own.This book, based on a study on Constitutionalism in Zimbabwe, provides the people of Zimbabwe with a constitution-making process that should lead to the creation of a multiparty constitutional democracy in the country as a permanent solution to the nation's serious problems.The central role that people should play in the constitution-making process is analyzed. Obstacles to a people-driven constitution-making process are identified and analyzed.The analysis should result in empowering individuals,political parties, civil society bodies, government,and the international community with information that may make them more effective in fulfilling their mandates. 76 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Qualitative and quantitative trade information on West Africa has remained a scarce resource for several decades. Thus, seaports in the region, that are maritime corridors to the landlocked countries (LLCs) of Burkina Faso, Mali and Niger, compete in a vacuum without any reliable basis to assess their individual competitiveness vis-à-vis the regional market. This book, therefore, provides an analysis of transit trade and transport with emphasis on five seaports used by the three LLCs in West Africa. It assesses the LLCs seaborne trade type, volume, distribution and growth trend, and examines the competitive status of each of the transit corridors on the basis of regional share of transit traffic, distance, infrastructure, logistics costs, legal and institutional framework and overall quality of service. The book provides sufficient and necessary overview of the transit trade and transport sub-sector in West Africa. It can serve as a working document for a sustainable transit trade development in any corridor and would, therefore, be useful to maritime trade and transport sector professionals, researchers and policy makers of both coastal and landlocked countries. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Whilst tourism development has brought economic prosperity for many people on Phuket (Thailand), it has also confronted the local population with the very negative impacts. Especially for the people 'excluded' - the locals not actively participating in tourism and unable to take advantage of the development - the negative impacts in the environmental and socio-cultural sphere are extremely evident. Also in economic terms, the development of tourism has often worsened the situation for these 'excluded' since the costs of many everyday goods have increased. As is the case in many developing countries, tourism development has led to the reinforcement of socio-economic inequalities on Phuket. This study indicates and analyses the opportunities for Phuket to increase the participation of the locals 'excluded' from the tourism development process, in order to combat the socio-economic inequality within the local population at the destination. 96 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This work addresses the problem of finding the minimum number of vehicles required to service weekly a set of customers subject to time windows. The specific structure of the problem requires that a full loaded vehicle serve only one customer each time it leaves the depot. As a consequence, all feasible schedules involve the same total distance traveled. The fleet is homogeneous and is located in a common depot. Vehicle capacity is finite, weekly mileage is limited, and split service is not permitted. Four heuristics are developed to obtain feasible solutions. Results are reported for 1000 randomly generated problems with up to 150 deliveries. It is shown that the new heuristics outperform the actual algorithm used by the Transportation Company in terms of computation time and the quality of solution. To gauge the quality of the solutions, three lower bounding procedures are developed. The first considers the 'bin packing aspect of the problem' with regard to the maximum weekly mileage. The second exploits the time windows constraints while the third lowerbounding method uses a network flow formulation. 48 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This study explores the emergence of the profession of public relations in the recently democratic Russian Federation. The significance of this research is embedded in the need to understand the status of public relations in Russia, where few studies about public relations have been conducted. The purpose was to identify whether public relations practitioners in Russia practice Grunig and Hunt's (1984) models of public relations; how public relations has contributed to the political and economic transformation in Russia; and how the former communist propaganda has affected contemporary public relations. This book represents a contribution to the global body of knowledge about public relations. The Russian perspective augments this knowledge concerning a country where prior research has been scant. The goal of this study is to detect patterns that could guide future research involving Russian public relations. Additionally, principles discovered from this study could be meaningful to business entities desiring to mount effective PR campaigns. 92 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A classification is given of certain separablenuclear C -algebras not necessarily of real rankzero, namely, the class of simple C -algebras whichare inductive limits of continuous trace C -algebraswhose building blocks have spectrum homeomorphic tothe closed interval [0,1]. In particular, aclassification of simple stably AI algebras isobtained. Also, the range of the invariant is calculated. We start by approximating the building blocksappearing in a given inductive limit decomposition bycertain special building blocks. The special buildingblocks are continuous trace C -algebras with finitedimensional irreducible representations and such thatthe dimension of the representations, as a functionon the interval, is a finite (lower semicontinuous)step function. It is then proved that theseC -algebras have finite presentations and stablerelations. The advantage of having inductive limitsof special subhomogeneous algebras is that we canprove the existence of certain gaps for the inducedmaps between the affine function spaces. These gapsare necessary to prove the Existence Theorem. Alsothe Uniqueness theorem is proved for these specialbuilding blocks. 88 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -While runtime compilation has in practice been largely restricted to programming languages that execute on virtual machines, such as Java and C#, parallel OpenMP programs show many promising traits for efficient and effective runtime optimization. This work introduces stOMP: a specializing thread-library for OpenMP. Using a combined compile-time and run-time system, stOMP specializes OpenMP parallel regions for frequently-seen values and the configuration of the runtime system. We present a detailed description of the system, focusing on the optimizations implemented and techniques to minimize the runtime overhead: a context-based hot-spot detector; a pruning mechanism that eliminates poorly behaved variables as specialization targets; several runtime optimization policies; and several code optimizations and transformations that further allow performance improvement. We evaluate our work on the SPEC OMP benchmark suite, showing a performance increase of up to 7.8%. 96 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This study concerns with designing bus routes network and determining bus frequencies, while the total passenger travel time, including in-vehicle travel times, waiting times, transfer times and transfer penalties, is minimized. An iterative heuristic algorithm, modified from Lee (1998), with integrated routing and frequency setting is applied in this study. To process the significant amounts of data that are involved in the procedure and to provide graphical presentation of the resulted routes, the heuristic algorithm is embedded with the Geographic Information Systems (GIS). The procedure gives a potential result that has less total travel time of the network when compared with other studies. The algorithm has been applied to the case study, one operation zone of the Bangkok Mass Transit Authority, Bangkok, Thailand. The study area consisted of 23 zones. Compared with the existing bus network, the algorithm produced less numbers of routes and buses. The resulted routes of this study satisfied all demands within the study area, while it is not the case with the existing network. 112 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Anaplasma phagocytophilum is an emerging tick-bornepathogen of humans, horses, sheep, dogs, andwildlife. In humans, granulocytic anaplasmosis (GA)may be associated with pyrexia, headache, myalgia,nausea, and ataxia, organ failure, susceptibility toopportunistic infections, neuritis, or respiratorycomplications with a case fatality rate up to 5% insome areas. The putative reservoir for A.phagocytophilum in the western United States is thedusky-footed woodrat (Neotoma fuscipes). Evidence toimplicate the woodrat as the reservoir includes highPCR- and seroprevalence in enzootic areas, frequentinfestation with the tick vector, Ixodes pacificus,and results of experimental infection studies thatshow woodrat infection persisting for 1-8 months.Unlike in the eastern United States where a singlevector species and a dominant reservoir host speciesmaintain a sylvatic cycle, in the western US, thereare multiple ecologically significant reservoir hostsincluding gray squirrels (Sciurus griseus) andchipmunks (Tamias spp.). The goal of this researchwas to identify the role of a number of abundant butpotential reservoirs for A. phagocytophilum in theWestern United States. 52 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book covers the development of a power system for an autonomous self-sufficient agricultural robot. The robotic system, designed for precision agriculture applications, was augmented with a new power system, to accommodate a solar energy source for recharging the batteries. The power system consists of a custom-made solar panel, a maximum power point tracker (MPPT), and power monitoring sensors. To increase the whole robotic system energy efficiency, the power system was programmed to monitor the intake and output, and to optimize its power usage accordingly. The robotic system was tested in field conditions, simulating the performance of useful tasks with its actuator. The tests were performed in order to demonstrate the improved run time of the system between manual battery recharges. This book presents the augmentation of the new robotic power system, the tests performed on the robotic system, the results of the performed tests, and a discussion of the results and possible improvements that can be made to the system. 80 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Security issues in Wireless sensor networks (WSNs) mainly come from attacks. In general, the attacks in WSNs can be classified as external attacks and internal attacks. In an external attack, the attacking node is not an authorized participant of the sensor network. Cryptography and other security methods can prevent some of external attacks. However, node compromise, the major and unique problem that leads to internal attacks, will eliminate all the efforts. Knowing the probability of node compromise will help systems to detect and defend against it. Although there are some approaches that can be used to detect and defend against node compromise, few of them have the ability to estimate the probability of node compromise. Hence, we develop basic uniform, basic gradient, intelligent uniform and intelligent gradient models for node compromise distribution in order to adapt to different application environments. These models allow systems to estimate the probability of node compromise. Applying these models in system security designs can improve system security and decrease the overheads nearly in every security area. 108 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This research discussed the relationship of organic material characteristics and thermal maturity versus hydrocarbon potential. The purpose is to establish the reliable indices of synthetic assessment of organic matter in the evaluation of petroleum potential. In addition, it is to present new guidelines for improved assessment of the kerogen type, generative potential and thermal maturity using Rock-Eval parameters. The analytic results indicate that petroleum generation potential is completely exhausted at a vitrinite reflectance of 2.00-2.20% or a Tmax of 510-520°C. A decline in BI signifies the start of the oil expulsion window and occurs within the vitrinite reflectance range 0.75- 1.05% or a Tmax of 440-455 oC. The petroleum potential can be divided into four different parts based on the cross-plot of HI vs. %Ro. The area with the highest petroleum potential is located in section B with %Ro=0.60-1.00%, and HI100. The start of the oil expulsion window occurs within the %Ro range of ~ 0.75-1.05%Ro or the Tmax range ~ 440-455° C and the total oil window extends to %Ro = ~ 1.25- 1.95 or Tmax = ~ 465-525°C. 152 pp. Englisch.

Approaches to overcome the shortcomings of thermal bonding processes in obtaining of high strength spunbond fabrics are also discussed. This book should be useful to scholars and professionals whose areas of interest include ultra fine and bicomponent fibers, nonwovens, thermal bonding, and melt spinning. 180 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Morphodynamics of sedimentary systems is nowadays a fundamental piece of knowledge for civil and environmental engineers involved in fluvial and lagoonal interventions. While morphodynamics is in principle an extremely complex discipline, some fundamental results may be achieved with relatively simple models. The work provides an analysis of a number of simplified models, discussing the usefulness of their approach and the limits of their applications. The entire study is especially on the analytical and numerical analysis of simplified one-dimensional formulations of fluvial morphodynamics and two- dimensional formulations of lagoon morphodynamics. The effects of geometry, hydrology and sediment input unsteadiness and non-uniformities have been studied, considering the validity and limitations of the local uniform water flow hypothesis or other useful simplifications. General results and further developments underline however, that all simplified models analyzed require further verifications against experimental or field measurements. 152 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Internet has potential to deliver information to Web users that have no other way of getting to those resources. However, information on the Web is scattered without any proper semantics for classifying them and thus this makes information discovery difficult. Thus, to ease the querying of this huge bin of information, developers have built tools amongst which are the search engines and Web directories. However, for these tools to give optimal results, two factors need to be given due importance: the users' ability to use these tools and the bandwidth that is present in these environments. Unfortunately, after an initial study, none of these two factors were present in Mauritius where low bandwidth prevails. Hence, this study helps us get a better idea of how users use the search tools. 84 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Wind farms are a proven environmentally sound and economically viable means of generating renewable energy. Energy security and sustainability are central to New Zealand's economic future. Population and economic growth and energy intensive industries are rising New Zealand's appetite for electricity. Recent power crisis along with the green image of New Zealand have reinforced the need to take positive steps to ensure a reliable, renewable and sustainable electricity supply for this country. But wind farm projects tend to face opposition at the local level because of its various potential environmental and socio-economic impacts. Therefore, gaining public acceptance becomes one of the most important factors for successful wind farm development. This book identifies the potential impacts of wind farm development with specific attention to those impacts and public dynamics surrounding wind farm development considering the policy context of New Zealand. It also looks into domestic and international wind farms along with drawing out the success and/or failure characteristics with respect to consultation, and impact mitigation providing empirical evidence from New Zealand. 108 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Very little research exists on the topic of computer cursor design and utilization. Since this is an important area in successful and efficient user interaction with graphical user interfaces, additional study is necessary. To investigate the impact of cursors with no implicit directional cues (orientation-neutral cursors) on movement time, positioning performance, and stimulus-response compatibility, six experiments were designed. In these experiments, six orientation-neutral cursors were compared against each other as well as against four directional cursors. All experiments measured two dependent variables, movement time and positioning performance. Statistical analysis tests revealed a correlation for some cursor types between the two dependent variables, while changing target shapes indicated no statistical significance on the overall results. This study concludes that there is no one cursor of those tested that performed best for anyone. This research should be especially useful to professionals in Computer Science or Cognitive Psychology interested in HCI, design of Graphical User Interfaces, or mental representations of visual space. 88 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Analysis and design of communication systems in today's dynamically changing environment face a lot of challenges. Networks can become overloaded at one moment and underutilized at the next. In a randomly changing environment, such as time-varying arrivals, variable bandwidth demands, data traffic integrated with streaming traffic, and burst traffic with correlated arrivals, performance and dimensioning issues become very complicated. Little research has been carried out on dimensioning a system in such an environment to meet quality of service requirement. In this dissertation, one of our contributions is providing efficient dimensioning algorithms in closed-form with a constant or near linear complexity. Analytical models and efficient dimensioning algorithms are then proposed for different Scenarios. 120 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This work bases on the PhD thesis, defended by the author at Tallinn University of Technology in 2003. The work summarizes the main results of author's scientific work in the field of modeling and simulation of phase locked loops (PLLs). The book explains the modeling principles and presents the solutions of problems, for which the designed computer models and simulators were used. As a result, a set of parameters for adequate behavior of the PLL in respective applications is proposed. The scope of modeling and simulation is limited by the analog (classical) and mixed analog/digital structures of the PLL, while two methods for system level modeling (phase-domain and signal-domain modeling) are treated. Dealing with different PLL topics makes the book somewhat eclectic, but helps to apprehend and recognize the benefits of using simple and fast running models as an alternative to expensive commercial software tools for behavioral simulation of PLLs. It might encourage the researches, engineers and students to use cheap general-purpose software for developing self-made models for the study of dynamics and exactness of performance as PLLs as well as other nonlinear dynamic systems. 104 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A novel scheme is presented for an iterative decambering approach to predict the post-stall characteristics of wings using known section data as inputs. The new scheme differs from earlier ones in the details of how the residual in the Newton iteration is computed. With earlier schemes, multiple solutions are obtained for wings at high angles of attack as the final converged solution depends on the initial conditions used for the iteration. With this scheme, multiple solutions at high angles of attack are brought to light right during the computation of the residuals for the Newton iteration. In general, the new scheme is found to be more robust at achieving convergence. Experimental validation is provided using experimental airfoil lift curves from Naik and Ostowari for three different aspect ratios of rectangular wings. Results are presented from a study of the stall characteristics of wings of different planform shapes and two configurations of a wing-tail and a wing-canard configuration. Results are also presented from a study to investigate possible asymmetric lift distributions when the iterations were started with an initial asymmetric distribution of the decambering. 108 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Road and traffic sign recognition is one of the important fields in the Intelligent Transport Systems (ITS). This is due to the importance of the road signs and traffic signals in daily life. They define a visual language that can be interpreted by the drivers. They represent the current traffic situation on the road, show the danger and difficulties around the drivers, give warnings to them, and help them with their navigation by providing useful information that makes the driving safe and convenient. The main goal of automatic traffic sign recognition is to extract traffic signs from images of complex scenes under uncontrollable illumination. This book gives a description of the way to extract the traffic signs from the images taken for the roads. 264 pp. Englisch.
