Providing advanced 3D interactive facilities to users of a client-server collaborative modeling system presents a great challenge when thin clients are involved, mainly due to their lack of both a full-fledged CAD model and adequate modeling and solving functionalities. This paper presents a new approach that provides a convenient representation of feature model data suitable for direct manipulation of feature models at such clients. In particular, feature handles are proposed to support interactive feature editing. This approach combines all advantages of a thin client approach with the sort of 3D direct manipulation facilities usually only found in powerful standalone CAD systems.

Understanding of algorithms is one of the most challenging aspects of the study of computer science. Over two decades of research has been devoted to improving techniques to learn and teach algorithms. In this work, we present a new approach for explaining algorithms that aims to overcome various pedagogical limitations of the current visualization systems. The main idea is that, at any given time, a learner is able to focus on a single problem. This problem can be explained, studied, understood, and tested before the learner moves on to study another problem. The structured hypermedia algorithm explanation (SHALEX) system is the system we designed and implemented to explain algorithms at various levels of abstraction. In this system, each abstraction is focused on a single operation from the algorithm using various media, including text and an associated visualization. The explanations are designed to help the user to understand basic properties of the operation represented by this abstraction, for example its invariants. SHALEX allows the user to traverse the graph-based algorithm model, using a top-down (from primitive operations to general operations) approach, a bottom-up approach, or a mix of these two approaches. Since the system is implemented using a client-server architecture, it can be used both through distance education and in the classroom setting. To aid and monitor the leaner, we also developed an agent in SHALEX that provides help and monitors the completion rate.

The potency and effectiveness of the knowledge systems, in some ways, rely upon its design and the way knowledge area unit transmitted among totally different parties. Similarly, a really crucial side within the computer code development is that the security of knowledge that flows through open communication channels. one in all the foremost widespread design is client/server design that creates the centralization of knowledge storage and process modify, and supply flexibility for applying authentication strategies and coding algorithms inside info systems. whereas the amount of shoppers increase, its need increasing the authentication and coding level as high as potential. Client/server could be a technology that enables to open associate degree interactive session between the user's browser and also the server. during this study, we tend to used client/server design to accomplish secure messaging/chat between shoppers while not the server having the ability to decode the message by applying 2 layer security: one layer of coding between the shoppers and also the server, and also the second layer of coding between the shoppers within the chat space. during this manner, a shopper / Server Cryptography- based mostly Secure electronic messaging System mistreatment RSA (Rivest- Shamir-Adelman), that could be a wide used public-key cryptography and authentication system for encryption of digital electronic messaging transactions like email over the computer network, extranet and net, to write in code and decipher messages in an exceedingly terminal window is developed.

Services to customers that have not been optimal with the implementation of the note-taking model, recording and making reports to the leadership that are still often a complaint for officers is the forerunner to this research. To overcome the problem that was complained about, then carried out steps that could help facilitate the service in the garbage bank. The solution offered is with the Client Server Design of Sukorejo Refuse Bank Application, so that services to customers can be done effectively and efficiently and can report quickly enough. With the service model that has been assisted by the application of the refuse bank, it is expected that it can also help improve the performance of officers. So that the process of designing this system is more directed, then the system development model is used with the waterfall method. The use of this method is chosen based on the consideration of the scope of application that only interacts within the internal Sukorejo refuse bank itself, therefore it is chosen because the scope of the application is still small scale. This system will be built with the Client Server by considering that one computer unit is reserved for the server and the other can be used as a workstation or client. This application will be created using Visual Basic 2010 and the MySQL database. With this system, it can reduce the problems in the refuse bank, so that the garbage bank can provide better service.
