My thesis investigates the collaboration and evolution of micro controller networks. In the thesis, I have developed a framework for flexibly connecting embedded systems, called microsynergy. The framework gives to users the ability unify a network of micro controller-based devices into logically defined collaborative networks. It establishes a communication infrastructure across a variety of networking protocols and allows dynamic reconfiguration of the micro controller network by means of a visual language. The infrastructure includes a mechanism for the construction and/or reuse of stateful coordination logic that manages the inter-communication of the network enabled devices and software components to create new functionalities and behaviours from a set of predefined software and hardware components. microsynergy looks at only a few of the issues, such as how to integrate devices with minimal impact on the code base, integrating devices of various protocols, building easy to understand and modifiable networks of devices that can act as a unified system. It include the design, implementation and analysis, through an informal user study, of a specific implementation of visual programming paradigm and its relation to collaborative networks.

Students today lack both time and money. At the same time e-commerce is increasing, and especially food sales over the internet. This report aims to explore the possibilities of a service that offers students a simple alternative for high quality food within their budget in the form of a web application. Students at Campus Valla expressed the need for such a service through a market research. The study was conducted by researching theories regarding usability and navigability. Students as a group often lack time and are used to getting fast and clear information; this is ensured by good navigability. After the researching of theories, several user tests were conducted on the targeted group. The result following this was the development of the web application Heat n' Eat. In order to achieve good navigability, the application was implemented with a simple layout, focusing on the products. A final user test showed that the application could be considered usable with focus on navigability. / Studenter idag har brist på både tid och pengar. Samtidigt ökar e-handeln och specifikt matförsäljningen över internet. Rapporten har som avsikt att undersöka möjligheterna för en tjänst, i form av en webbapplikation, som erbjuder studenter högkvalitativ mat inom deras budget på ett enkelt sätt. Via en marknadsundersökning på Campus Valla uttryckte studenter avsaknad av en sådan tjänst. Studien genomfördes genom att ta fram teori rörande användbarhet och navigerbarhet. Studenter som grupp har ofta ont om tid och är vana vid att få snabb och tydlig information vilket god navigerbarhet säkerställer. Efter teoristudien genomfördes användartester på målgruppen. Som ett resultat utvecklades webbapplikationen Heat n’ Eat. För att uppnå god navigerbarhet blev utformningen en simpel struktur med produkterna i fokus. Ett avslutande användartest visade att webbapplikationen kan anses vara användbar med fokus på navigerbarhet.

Approved for public release; distribution is unlimited / The certification process can be defined as a comprehensive evaluation of all security features, both technical and nontechnical, of an information system. This process ensures that the system design and implementation meets a distinct set of prescribed security requirements. The accreditation of a system ensures that networks, applications, and operating systems that make up the system are running at an acceptable level of risk. The Designated Approving Authority (DAA) is responsible for deciding what systems to approve for accreditation, and assumes the responsibility for running the accredited system at an accepted level of risk. This analysis of the certification and accreditation process stresses the vital aspects of the process that are of special concern to the DAA. The mission drives the process, and influences the ultimate accreditation decision. The DAA must understand the fundamental aspects of the certification effort, and be able to weigh factors such as the funding, time, and other resources available for the effort, as well as understand the scope of the system as a whole. This thesis covers the vital aspects of certification and accreditation, and provides the new DAA with a guide to the process. / Naval Postgraduate School author (civilian).

M.Com. (Informatics) / In this study the issue on User Interface Management Systems (UIMSs) is addressed. Specific attention is given to the design principles regarding development of user interface management systems that allow the creation of graphical user interfaces for existing text-oriented command-line applications. As an introduction the concept of user interface management systems is discussed and a working and formal definition is derived. Thereafter a survey is discussed concerning user interface tools. A user interface management system architecture is proposed; \he planning, design and development aspects of user interface management systems are addressed, and the effect of human factors in the design of a user interface management system is discussed. Attention is also given to various interaction and dialogue models ...
