Abstract

Since its conception, Proof-Carrying Code (PCC) woke up the interest of the research community and several methods based on this technique were developed. This technique guarantees that untrusted programs run safely in a host machine. In a PCC framework, the code producer equips the produced code with a formal proof establishing that the code satisfy the consumer's security policies. So, the code consumer only needs to verify such proof before the execution of the mobile code.

On the other hand, static analysis is a technique us ....etc

Attacks against Wireless Sensor Networks (WSNs) are becoming more and more frequent. Due to the sensitive nature of these networks, appropriate security mechanisms should therefore be developed. This seminar introduces a fault-tolerant approach for WSNs. The basic idea to detect malicious nodes is to proceed to intermediate verification of the signed messages within the communication paths. A tolerance state is defined in which a set of tests are performed on the malicious node in order to definitely reject it or rehabilitate it. ....etc

The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation. This makes it easier for machines to automatically process and integrate information. XML's ability to define customized tags and RDF's flexible approach to represent data could be exploited to build Semantic Web. RDF (Resource Description Framework) is used to represent information and to exchange knowledge in the Web. In extension to this several standard Ontolog ....etc

A Novel Framework for Semantic Annotation and Personalized Retrieval of Sports Video

Sports video annotation is important for sports video semantic analysis such as event detection and personalization. We propose a novel approach for sports video semantic annotation and personalized retrieval. Different from the state of the art sports video analysis methods which heavily rely on audio/visual features, the proposed approach incorporates web-casting text into sports video analysis.

Compared with previous approaches, the contri ....etc

Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadata model using XML but which has come to be used as a general method of modeling knowledge, through a variety of syntax formats (XML and non-XML).

The RDF metadata model is based upon the idea of making statements about resources in the form of a subject-predicate-object expression, called a triple in RDF terminology. One way to represent the fact 'The sky has the colour blue' in RDF would be as a triple whose sub ....etc

Garbage Collection is an automatic memory management mechanism in .NET. This mechanism helps to free the memory automatically when they are no longer used by the application. The advantage is that developers need not worry about the memory management when writing the code i.e. the GC will do it for you as and when needed.Manual memory management that is done in c and c++ language is (programmer-)time consuming, and error prone.Hence .Net Framework provides with automatic garbage collection to avoid the above problem.And this is imple ....etc

Abstract

Businesses, schools can benefit greatly from technologies that enable information sharing through videoconferencing systems. Researchers at the University of Pittsburgh have developed a highly programmable and replicable solution. Using an IP-based network connection, small electronics and application programming interfaces of the Java Media Framework (JMF) v2.1.1, developers have created a flexible videoconferencing system that permits users to connect to one camera or many, remotely control a camera's pan and tilt angle and adjust ....etc

It would be hard to imagine a worse model for user interface development than HTTP. Would you use a GUI framework where every event from every widget in your application was handed to you at once, periodically, as a large hashtable full of strings? Where every time a single piece of data changed you had to regenerate a textual description of the entire interface? Where the event-based architecture was so strict that you couldn't ever, under any circumstances, open a modal dialog box and wait for it to return an answer? Those are the costs of u ....etc

Hamlets (previously known as IBM Servlet-based Content Creation Framework) is the name of an open source system for generating web-pages originally developed by René Pawlitzek at IBM. He defines a Hamlet as a servlet extension that reads XHTML template files containing presentation using SAX (the Simple API for XML) and dynamically adds content on the fly to those places in the template which are marked with special tags and IDs using a small set of callback functions. A template compiler can be used to accelerate Hamlets. Hamlets provid ....etc
