Revision with unchanged content. This study investigated the influence of computer-generated reminders on the rate in which distance learners submitted assignments and completed courses. The computer-generated reminders, sent via email, served as a time management support strategy. Participants were randomly divided into two groups: control and treatment. Both groups received a list of target due dates for course assignments. The control group did not receive reminders. The treatment group received reminders when they failed to submit an assignment by a target due date. The results indicated no significant difference between the control and treatment groups in terms of assignment submission rates and course completion rates. However, results of this study did reveal that the number of assignments in a distance course influences the timeliness of assignment completion and the likelihood of course completion.
The problem of distributing goods from depots to consumers plays an important role in the management of many distribution systems, and therefore when it is programmed efficiently it may yield significant savings. In a typical distribution system, trucks provide pick-up and delivery services to customers that are geographically dispersed in a given area. In many of its applications, the main objective of distribution is to find a set of routes for such trucks, satisfying a variety of constraints, so as to minimize the total distribution cost. This work focuses on a decision model for a real world problem. The problem reveals itself as assignment of trucks to routes by Latex Foam Rubber Products Limited-Kumasi, Ghana. This study addresses the problem of finding an efficient assignment of the limited number of trucks at the company’s disposal to the routes they ply while serving its customers outside the metropolis. In this work we use a solution procedure based on Munkres Assignment Algorithm for optimal assignment of non-homogenous fleet of trucks to a given set of routes, where Latex Foam Rubber Products Limited-Kumasi, distributes its products to its customers.

This book explains the port operations and proposes approaches that aim to improve the most important successive steps in container terminal management activities. A multi-period assignment problem that seeks to allocate vessels to berthing spaces and quay cranes is proposed to handle the quayside operations. Subsequently, on the yard side, a discrete-event simulation model for the real life detailed processes performed during the handling of import containers is developed. In particular, the model focuses on the storage assignment problem at the operational level in a container terminal with a multiple-berth structure. An approach by means of a hierarchical structure is adapted to partition the assignment problem into two sub-problems and solve each of them using separate decision rules. Suggested storage policies are evaluated in view of the overall performance of the container terminal.
The focus area of this paper is on the assignment problem with budget constraints which is one of the application area of combinatorial optimization that operates on the domain of those optimization problems,in which the set of feasible solutions is discrete or can be reduced to discrete,and in which the goal is to find the best solution. It is particularly concerned with solving the unconstrained assignment problems with Hungarian algorithm and the constrained assignment problem by cutting plane or outer linearization algorithm for solving the Lagrangian dual problem in which, at each iteration,the function that approximates the dual function is optimized. The paper is divided in to two chapters. In the first chapter,the classical assignment problem,the problem of finding optimum (minimum or maximum) cost or profit assignment a set of workers or resources to jobs or activities to gather with its mathematical formulation,solution methods and special cases in assignment problems were considered. Under the second chapter, we have considered generalization of the classical assignment problem concerning resource(or budget) constraints, due to the variety of real life problems.
Modern day public transport assignment faces lots of problems. Solutions may exist but needs some form of backings. A sensitivity analysis in most cases could just be sufficient to provide this backing. The developments in this book are very important for students, academic researchers and policy makers. The book provides an extensive review on transit assignment, sensitivity analysis and OmniTRANS. It highlights important conclusions such as:- - Passenger access-egress distances significantly affects their access stop choices. - The travel distance parameter of the generalized cost function has the highest influence on transit assignment - The number of transfers to be made by passengers significantly determines their generalized cost of travel - A carefully conducted partial sensitivity analysis can provide better predictions than a Monte-Carlo sensitivity analysis. As a policy advice to public transport operators in Flanders-Belgium, the developments in this book suggest that; to improve transit assignment, it is sufficient to reduce passengers access-egress distances & the number of transfers either through the institution of more direct transit lines or missing links.

This study focused on two women’s golf teams associated with NCAA Division III colleges. The women that participated in the study had handicaps ranging from six to twenty respectively before engaging in the program. The teams in the study consist of two of the top three programs in a Midwest NCAA Division III conference. All of the participants were given a pre-test questionnaire at the beginning of the study. This study was done to investigate if Auditory Literature, written by Dr. Bob Rotella addressing mental toughness, affects a Division III Women’s Golf Team’s mental toughness. Dr. Rotella is one of the world’s most successful sport psychologists. Four sources guided this study; Golf is not a Game of Perfect, Golf is a Game of Confidence, Putting out of Your Mind, and The Golf of Your Dreams. The effectiveness of the audio literature treatment on a Division III Women’s Golf Team was determined through data from the Test of Performance Strategies Questionnaire (TOPS) via a pre and post test comparison of a control group of Division III golfer’s with similar playing abilities and an experimental group.
A partition of n is a division of n into any number of positive integral parts. Then the sum of the integral parts is n. The order of the parts and arrangement in a division of n are irrelevant and the parts are arranged in descending order. We denote the number of partitions of n by P(n). We introduce a brief survey of Ramanujan’s partitions congruences. We mainly concern with combinatorial aspects of the congruences moduli 5, 7 in terms of the rank and crank of vector partitions separately.
A wireless mesh networks (WMNs) has emerged recently, WMN consist of two types of nodes mesh routers and mesh clients.WMN is dynamically self-organized and self-configured, with the nodes in the network automatically establishing and maintaining mesh connectivity among themselves. Channel assignment is a critical issue in WMN which is the mapping between the available channels and the radios at each node such that the network performance is optimized, and hence the focus of this work along with static channel assignment, multi-radio, multi-channel. Multi-radio MAC can potentially achieve higher network capacity than single-radio MAC. We design and implement a new agent (DSBCA) distributed channel assignment spanner base, the routing protocol Optimize the network performance considering the throughput, end-to-end delay, connectivity and the interference of our channel assignment algorithm. Base on the network simulations NS2.34 on Linux Fedora and our proposed channel assignment algorithm improved the throughput, minimal-connectivity preserving channel assignment algorithm.
The highly competitive environment in today's wireless and cellular network industries is making the management of systems seek for better and more advance techniques to keep masses of data, complexity of systems and deadline constrains under control with a lower cost and higher efficiency. Therefore, the management is getting significant attentions by researchers in order to increase the efficiency of the resource usage to provide high quality services. Two of the cornerstones of the management system in wireless and cellular network are carrier assignment and packet scheduling. Therefore, this work focuses on analysis and development of carrier assignment and packet scheduling methods in multi-band Wi-Fi and LTE-A networks.
The albino visual system is characterised by a range of abnormalities including a severe rod deficit, an underdevelopment of the central retina and a misprojection of a portion of the temporal ganglion cells. During development of the retina levels of proliferation and apoptosis are elevated, and the maturational gradient is delayed. During my PhD I systematically characterised the nature of these developmental abnormalities and examined the effects of L-DOPA (a precursor in melanin/dopamine synthesis pathways that is thought to be depleted in the albino retina) on patterns of cell division. The findings were consistent with a model in which reduced levels of L-DOPA in the albino retina lead to spatiotemporal defects in patterns of cell division, potentially as a result of secondary consequences on concentrations of retinal dopamine.
The efficient management of Change Requests (CRs) is fundamental for successful software maintenance; however the assignment of CRs to developers is an expensive aspect in this regard, due to the time and expertise demanded. To overcome this, researchers have proposed automated approaches for CR assignment. Although these proposals present advances to this topic, they do not consider many factors inherent to the assignments, such as: developers’ workload, CRs severity, interpersonal relationships, and developers know-how. Actually, as we demonstrate in this work, CR assignment is a complex activity and automated approaches cannot rely on simplistic solutions. Ideally, it is necessary to consider and reason over contextual information in order to provide an effective automation. Beyond investigating all these aspects through an extensive systematic literature review, this work also proposes a context-aware architecture solution to semi-automated assignment of CRs.

To use the available bandwidth in optical communication systems different multiplexing techniques are adopted, so that multiple users can access and use the bandwidth efficiently. The most common techniques are frequency division multiplexing, time division multiplexing, optical code division multiplexing, wave length division multiplexing and dense wavelength division multiplexing. Absolute Polar Duty Cycle Division Multiplexing over wave length division multiplexing technique is another technique which increases the channel count from other conventional existing systems. However, AP-DCDM-WDM system faces the non-linearities as like the other conventional system which affects the spectral efficiency. There is a need to study the effect of non linearities, especially effect of four wave mixing on this technique, to make this technique more efficient and powerful by taking suitable measures against the non-linearities.

Stress in Moroccan Arabic, and also in other languages, poses challenging problems for phonological theory. This is due to the fact that stress exhibits conflicting properties; which makes it difficult to provide answers to a number of issues. This book provides an investigation into a prominent aspect of prosodic phonology in Moroccan Arabic (a case study of the dialect of Rabat city), namely, stress assignment in the grammatical category of verbs within the framework of optimality theory as proposed in Prince and Smolensky and McCarthy and Prince. It particularly addresses a range of issues such as: the position of stress, the basis on which stress is located, the factors on the basis of which stress location is effected, the importance of the perceptual and the instrumental tests in shedding light on stress assignment, and the extent to which the optimality theoretic analysis confirm or disconfirm the results of the perceptual and the instrumental tests concerning stress placement. This book will be of interest to linguistics, teachers, researchers and to anyone interested in language study and phonological theory.
The size of the population in proportion to the food production is highly relevant in the level of development of a nation, as it has a direct bearing on the quality of life of the inhabitants. As the population of the Rajshahi division in Bangladesh grows rapidly and its trend varies regionally, it is important for the socio-economic planning purposes for a region to follow the regional trends of the dynamics of population and food production, both in space and through time. Considering the spatio-temporal dynamics and distinctiveness, the relationship between population growth and food supply in the Rajshahi division deserves special investigation. The Rajshahi division is situated in the north western corner of the Bangladesh facing various natural calamities like drought, frequent flood, river bank erosion etc. The population of Rajshahi division was increased at high rate during 1974, 1981 and 1991 and it was decreased in 2001. The food grain requirement is increased as well as population growth. It increased at 76.39 percent in the last 25 years. The food production was almost doubled in 2007-08 than the year of 1981-82.
Joy Division - Under Review is a 70-minute film covering the entire story of Joy Division - one of Manchester and post-punk's truly great bands. This documentary goes behind the scenes and discovers much previously uncharted territory: starting with the band's origins in early incarnation Warsaw, through their short but hugely impacting time as Joy Division proper and even touching on the remaining members' future following the tragic death of front man Ian Curtis. The programmer further reveals the work the band undertook with legendary producer Martin Hannett, the mad genius with whom Joy Division worked on both their stunning studio albums. The second of these, Closer, was to be a posthumous release for singer lan Curtis, and this DVD also digs deep into the troubled soul of this enigmatic performer whose personal life weighed him down, cruelly, just as the wider world was beginning to take notice of his intensely moving lyrics and arresting stage presence. The legacy of Ian Curtis, and Joy Division as a whole, is still felt strongly and they remain hugely influential to each new crop of forward thinking guitar bands.
Over the years, rapid development in computer technology has engendered simulation-based laboratory(lab) in addition to the traditional real (physical) lab. Many higher education institutions adopt simulation lab, replacing some existing physical lab experiments. The creation of new systems for conducting engineering lab activities has raised concerns among educators on the merits and shortcomings of both physical and simulation laboratories. Many arguments have been raised on the differences of both labs. In this book, we discuss the current trends and key issues in engineering laboratories including remote lab.We also investigating the effectiveness of real and simulation labs from students’ perspectives on their experience conducting both laboratories exercises. Specific suggestions to develop and design engineering laboratory education were proposed, which are deemed to be useful to educators and researchers who are working on engineering laboratory education and design.

The thesis focuses on student written plagiarism as a research problem. From prior research on plagiarism and scientific knowledge three hypotheses are developed: intentional plagiarism as an easy way to perform an assignment, unintentional plagiarism caused by misleading flow of digital texts, unawareness of instructions, and lack of feedback, and different identity of students, as opposed to scholars.
Assignment Problem is one of the first fundamental problems in the area of combinatorial optimization. Despite its historical roots, the problem has tremendous importance to date, due to its numerous real life applications in like facility location, personnel scheduling, job scheduling, production planning, project assignment, task assignment, time-tabling, vehicle routing, storage space allocation, etc. This book comprises some real life assignment and related problems involving imprecise cost/time parameters. In order to represent those imprecise parameters, interval numbers have been used here as this representation is the best among others. The associated problems have been solved using Genetic Algorithm efficiently. A salient feature of this book is that most of the algorithms have been written in a lucid manner with suitable examples using figures. This book should interest academicians, OR/GA practitioners and executives of different industries and business organizations.

This book is good for researchers who are working on optical networks and advancements in fiber optics communication. Mathematical models covered in this book are simple and easy to implement. A good number of routing and wavelength assignment algorithms have also been covered in this book which can be used to reduce blocking probability of the optical network. This book can be very helpful to the research scholars.
In this project, we have proposed an efficient re-routing algorithm by dynamic routing in Bi-directional WDM optical network. In wavelength division multiplexing network, a heuristic algorithm is used for routing and wavelength assignment. The main objective of this is to minimize the requirement of wavelength and hop length between S-D nodes in the traffic. In this project we have to considering a wavelength routed WDM optical network and then implementing Heuristic algorithm on it. We have to divide our work mainly into two phases. In the first phase, existing routing is performed using Dijkstra’s algorithm and in second phase of algorithm proposed algorithm is performed to reduce the number of wavelengths required in the first phase of the network which minimizes the hop count of each route.
This book is focused on the analysis of the representations of social support by families raising children with severe disabilities. The family situation is perceived as uncertain with problems occurring when dealing with them requiring social support from external resources. The understanding of social support is conceptualized by House (1981, cited in Peterson et al., 2009) and Tardy (1985, cited in Malecki and Demaray 2002, 1) who divide its content into emotional concern, instrumental aid, information, and appraisal. The concept of social support is used as unified in the defining of support from external resources. The main external resources are held to be the medical, social and educational systems, as defined in the Law of Social Integration of Disabled People (2005) of the Republic of Lithuania. Dolphin Assisted Therapy was engaged as a system taking a window place for analyzing social support on a legitimized social support basis. The book focuses on investigations into representations by families of social support during stressful periods of their lives, when social support acts as a stress-buffer.
WITH A NEW INTRODUCTION BY KATE MOSSE ‘You’re stale, tired of having to be tough. You want a change.

But greed and power have created a deadly opponent who will stop at nothing to get what he wants.
This book presents the basis for designing a control strategy for Shunt Active Power Filters used for the compensation of harmonic currents consumed by nonlinear loads. The design of the controller is carried out using the interconnection and damping assignment technique. The control objective is to inject the adequate compensation current into the power system, so that the grid current is sinusoidal and balanced, regardless of whether the grid voltage is distorted or unbalanced. This application uses a design methodology based on interconnection and damping assignment that allows trajectory tracking control because the references of the compensating currents are variable, and they depend on the performance of the load and the grid. References of the compensation currents are calculated by using Instantaneous Active-Reactive Power Theory.
This study is on the development of a remote Fiber Optic Communications laboratory. The system developed was based on the iLabs Shared Architecture. This architecture is a three-tiered platform that enables development, deployment and sharing of online experiments, as a supplement to conventional laboratories. The core objective of the research was to extend the functionality of the iLabs Shared Architecture to support experimentation in Fiber Optic Communications. A functioning prototype of the Interactive iLabs Architecture was implemented, and experiments in Bidirectional Fiber Optic Link and Wavelength Division Multiplexing design and tested. They were executed on the EMONA FOTEx board, an add-on board to the NI ELVIS II and powered by LabVIEW. Documentation that involved writing of Concept Paper, Proposal, System Requirements‘ Specification Document, Design Specification‘s Document, Research thesis and a scientific paper was also undertaken. This resulted in not only curriculum support through the designed experiments, but also tremendous capacity development in regards to software development, research, writing, organizational and presentation skills.
Although much as has been written on the subject of motivation, an attempt to uncover written literatures on motivation within the context of university support staff may appear a difficult task. This piece of work which is mainly the outcome of a review of relevant literatures and lessons gained from my experience while serving as a university staff in an African context starts by identifying who support staff in an institution of higher learning are and the reasons why they should be motivated. Informed by different motivational theories, it identifies management's catalytic role in support staff motivation which could result in a rise in work performance and subsequent progress of the university. Furthermore, this publication argues that support staff performance appraisal can be a useful tool to ascertain the effect of institutionalized motivational schemes on work performance. It concludes by maintaining that human motivation is complex as evident by variances in human needs, tastes and preferences. Therefore, an attempt to motivate university support staff may require an adequate need assessment of individual support staff. Get a copy of this book and find out more!!!
