How does technical education fit into today's society? What is the implication of the United Nations Decade of Education for Sustainable Development (2005-2014) for technical education? This book examines these questions. The author analyses the corresponding needs within technical education from various perspectives. She has identified different domains within the world of engineering including the domain of engineering profession and practice for manufacturing, design and development of technical solutions to fulfil the consumers' needs, the domain of technology assessment which considers potential impacts of technical solutions on human beings, and the domain of technical education as the foundation for engineering knowledge and skills. This book will be helpful to both researchers and practitioners in shaping the future of technical education.
We studied several existing works in similar problem field to understand how the project information are managed and tracked. Outcome of such studied has given us a better picture towards developing a solution for this project. After requirement analysis and studying similar problem domains in different organisation, we have designed a solution to demonstrate how we can solve our problem domain. This includes identifying different entities which interact with each other in order to pass information in a structure way. The interaction and dependency between entities are shown in the E-R analysis phase. The E-R (Entity Relationship) analysis is the foundation to design the database for the proposed solution. Based on the information we found from the work-flow (content-flow) and E-R analysis, the database tables have been identified and constructed. In order to demonstrate and prove our proposed solution, we have developed a prototype of the system (WPIS). This prototype is considered to be a pre-implementation phase of WPIS.
Chadian immigrants' presence in Maiduguri dates back to the city's foundation in 1907. Their migration from Chad was prompted by some "pull" and "push" factors.Many are fully integrated into the the local community through marriages. They were found to be highly multilingual. Hausa was found to be the most frequently used language in this community in most of the domains investigated.It is gradually replacing the ethnic language even in the core domain of Home settings.It has also superseded Chadian languages in two further domains:Traditional occasions and Association (language use of the second and third generations in particular), which are usually considered to be dominated by the Chadian lingua franca and the ethnic language respectively. And, the unexpected dominance of Hausa over Chadian Arabic as the intra-Chadian medium of communication would suggest that the latter might ultimately be less spoken by the settlers in the future. Since language remains an important symbol of ethnic identity, Chadian immigrants should strive to ensure its maintenance by always speaking the ethnic language both between the spouses (in endogamous families)and with the children at home.
Ontology has been a subject of many studies carried out in artificial intelligence (AI) and information system communities. Ontology has become an important component of the semantic web, covering a variety of knowledge domains. Although building domain ontologies still remains a big challenge with regard to its designing and implementation, there are still many areas that need to create ontologies. Information Science (IS) is one of these areas that need a unified ontology model to facilitate information access among the heterogeneous data resources and share a common understanding of the domain knowledge. Recently, the development of domain ontologies has become increasingly important for knowledge level interoperation and information integration.They provide functional features for AI and knowledge representation. Domain Ontology is a central foundation of growth for the semantic web that provides a general knowledge for correspondence and communication among heterogeneous systems. Particularly with a rise of ontology in the artificial intelligence (AI) domain, it can be seen as an almost inevitable development in computer science and AI in general.
High Quality Content by WIKIPEDIA articles! In information science, an upper ontology (top-level ontology, or foundation ontology) is an ontology which describes very general concepts that are the same across all domains. The most important function of an upper ontology is to support very broad semantic interoperability between a large number of ontologies accessible "under" this upper ontology. As the metaphor suggests, it is usually a hierarchy of entities and associated rules (both theorems and regulations) that attempts to describe those general entities that do not belong to a specific problem domain.
Energy exchange is a major foundation of the dynamics of physical systems, and, hence, in the study of complex multi-domain systems, methodologies that explicitly describe the topology of energy exchanges are instrumental in structuring the modeling and the computation of the system's dynamics and its control.This book is the outcome of the European Project "Geoplex" (FP5 IST-2001-34166) that studied and extended such system modeling and control methodologies. This unique book starts from the basic concept of port-based modeling, and extends it to port-Hamiltonian systems. This generic paradigm is applied to various physical domains, showing its power and unifying flexibility for real multi-domain systems.
Cyber-physical systems (CPS) involve deeply integrated, tightly coupled computational and physical components. These systems, spanning multiple scientific and technological domains, are highly complex and pose several fundamental challenges. They are also critically important to society's advancement and security. The design and deployment of the adaptable, reliable CPS of tomorrow requires the development of a basic science foundation, synergistically drawing on various branches of engineering, mathematics, computer science, and domain specific knowledge.This book brings together 19 invited papers presented at the Workshop on Control of Cyber-Physical Systems, hosted by the Department of Electrical & Computer Engineering at The Johns Hopkins University in March 2013. It highlights the central role of control theory and systems thinking in developing the theory of CPS, in addressing the challenges of cyber-trust and cyber-security, and in advancing emerging cyber-physical applications ranging from smart grids to smart buildings, cars and robotic systems.
Information and Communication Technologies provide for a long time already the backbone of telecommunication networks, such that communication services represent an elementary foundation of today’s globally connected economy. The telecommunication landscape has experienced dramatic transformations through the convergence of the Telecom and the Internet worlds. The previously closed telecommunication domain is currently transforming itself through the so-called NGN evolution into a highly dynamic multiservice infrastructure, supporting rich multimedia applications, as well as providing comprehensive support for various access technologies.The control layer of such NGNs is then of paramount importance, as representing the convergent mediator between access and services. The use and the optimization of the IP-Multimedia Subsystem (IMS) was researched and considered in this domain for many years now, such that today it represents the world-wide recognized control platform for fixed and mobile NGNs.Research on protocols and services for such NGN architectures, due to the convergence of technologies, applications and business models, as well as for enabling highly dynamic and short innovation cycles, is highly complex and requires early access to vendor independent - yet close to real life systems - validation environments, the so-called open technology test-beds.The present thesis describes the extensive research of the author over the last nine years in the field of open NGN test-beds. It focuses on the design, development and deployment of the Open Source IMS Core project, which represents since years the foundation of numerous NGN test-beds and countless NGN Research & Development projects in the academia as well as the industry domain around the globe. A major emphasis is given for ensuring flexibility, performance, reference functionality and inter-operability, as well as satisfying elementary design principles of such test-bed toolkits.The study also describes and evaluates the use of Open Source principles, highlighting the advantages of using it in regard to the creation, impact and sustainability of a global OpenIMSCore research community.Moreover, the work documents that the essential design principles and methodology employed can be reused in a generic way to create test-bed toolkits in other technology domains. This is shown by introducing the OpenEPC project, which provides for seamless integration of different mobile broadband technologies.
Many phenomena in engineering and mathematical physics can be modeled by means of boundary value problems for a certain elliptic differential operator in a given domain. When the differential operator under discussion is of second order a variety of tools are available for dealing with such problems, including boundary integral methods, variational methods, harmonic measure techniques, and methods based on classical harmonic analysis. When the differential operator is of higher-order (as is the case, e.g., with anisotropic plate bending when one deals with a fourth order operator) only a few options could be successfully implemented. In the 1970s Alberto Calderón, one of the founders of the modern theory of Singular Integral Operators, advocated the use of layer potentials for the treatment of higher-order elliptic boundary value problems. The present monograph represents the first systematic treatment based on this approach.This research monograph lays, for the first time, the mathematical foundation aimed at solving boundary value problems for higher-order elliptic operators in non-smooth domains using the layer potential method and addresses a comprehensive range of topics, dealing with elliptic boundary value problems in non-smooth domains including layer potentials, jump relations, non-tangential maximal function estimates, multi-traces and extensions, boundary value problems with data in Whitney-Lebesque spaces, Whitney-Besov spaces, Whitney-Sobolev- based Lebesgue spaces, Whitney-Triebel-Lizorkin spaces,Whitney-Sobolev-based Hardy spaces, Whitney-BMO and Whitney-VMO spaces.
