O. Box 18758 Sebha, Libya, Libyan. 2 Sebha University of Libya, Sebha, Libya. * Corresponding author. Tel.: 00218-925132935; email: [email protected] Manuscript submitted February 13, 2015; accepted July 5, 2015. doi: 10.17706/jcp.10.5.336-346 Abstract: Visual form description benefits from the ability of visualization to provide precise and clear description of object behavior especially if the visual form is extracted from the real world. It provides clear definition of object and the behavior of that object. Although the current descriptions of cryptographic protocol components and operations use a different visual representation, the cryptographic protocols behaviors are not actually reflected. This characteristic is required and included within our proposed visual model. The model uses visual form and scenario-based approach for describing cryptographic protocol behavior and thus increasing the ability to describe more complicated protocol in a simple and easy way. Key words: Animation, cryptographic protocols, interactive tool, visualization. 1. Introduction Cryptographic protocols (CPs) mostly combine both theory and practice [1], [2]. These cause protocol complexity describing and understanding. Therefore, separating the mathematical part from the protocol behavior should provide feeling of how the protocol works, thus increasing the ability to describe and to gain confidence in reflecting more complicated information about CPs, as well as to generate interest to know about other more complex protocol concepts. Several researchers realized the use of visual model and animation techniques to reflect the explanation of the learning objectives and their benefits [3]-[11].

Ph.D. Abstract: The spread of smartphone devices, Internet of Things technologies and the popularity of web-services require real-time and always on applications. The aim of this thesis is to identify a suitable communication technology for server and smartphone communication which fulfills the main requirements for transferring real- time data to the handheld devices. For the analysis I selected 3 popular communication technologies that can be used on mobile devices as well as from commonly used browsers. These are client polling, long polling and HTML5 WebSocket. For the assessment I developed an Android application that receives real-time sensor data from a WildFly application server using the aforementioned technologies. Industry specific requirements were selected in order to verify the usability of this communication forms. The first one covers the message size which is relevant because most smartphone users have limited data plan.

  • Communication Protocol for Schools
    Communication Protocol for Schools Communication plays a key role in creating and fostering strong, positive relationships between the school and the home. Communication is a two-way street; our schools share information with our families and community, and our families share information with our schools. The purpose of this document is to guide, manage and improve school-home communication by offering a standard format, structure and sequence for regular, ongoing communication. Communication Channels Communication can take place in a variety of formats. The message and the purpose of the communication can help determine which format is most appropriate. Generally, the more issues-driven and/or detailed the information is, the more direct the communication channel chosen should be. Communication channels include: Face-to-face communication – one-on-one meetings, School Council meetings, Parent-Student- Teacher interviews Telephone conversations Hard copy, written communication – letters sent home from the school, paper school newsletters Electronic communication – email, electronic newsletters, websites, social media When the communication requires a dialogue, such as bringing forward a question or concern or when a discussion is required on a particular topic, the preferred channels of communication are ones that allow for an immediate and ongoing interaction between the people involved. The best formats for this kind of communication are face-to-face conversations or telephone conversations. Schools and families are encouraged to use these direct channels of communication when a topic is complex or requires a dialogue. These more direct forms of communication also help us establish a personal connection, which helps build relationships that we don’t get in other forms of communication.

INTRODUCTION Voice over Internet Protocol also known as Voice over IP and VoIP is a communication standard for transmission of voice signal, data transmission and video conferencing. Actually this technology follow packet switching. In packet switching first the input signal (voice, data, video) converted into digital form so other operation becomes simple after this we do encoding, compressing of digital data to make more secure transmission through channel. Then after this we transmit the signal over the channel. At receiver side we do reverse of it but it also require an addition block before receiver to store packets and reorder these packets because in packet switching different Figure 1: Call flow of H.323 packets follow different path so reaches in random manner.

  • Web-Based Information Visualisation Using Javascript and Webgl
    Eurographics Conference on Visualization (EuroVis) (2014) Short Papers N. Elmqvist, M. Hlawitschka, and J. Kennedy (Editors) FluidDiagrams: Web-Based Information Visualisation using JavaScript and WebGL Keith Andrews1 and Benedict Wright2 1Institute for Information Systems and Computer Media (IICM), Graz University of Technology, Austria 2Institute for Software Technology (IST), Graz University of Technology, Austria Abstract Much attention has been focused on the provision of information graphics and visualisations inside a web browser. Currently available infovis toolkits produce graphical output by either injecting SVG nodes into the DOM or using the JavaScript Canvas 2D API. FluidDiagrams is a prototype information visualisation framework written in JavaScript which uses the WebGL 3D JavaScript API for its output, falling back to Canvas 2D as necessary, via the Three.js library. Six visualisations are currently implemented: bar chart and line chart, scatter plot and parallel coordinates for multidimensional data, and cone tree and hyperbolic for hierarchies. Anecdotally, visualisations using SVG nodes in the DOM for output can become rather sluggish when display- ing more than a few dozen items. Visualisations using Canvas 2D exhibit similarly slow performance. WebGL utilises hardware acceleration where available and promises much better performance for complex visualisations, potentially in the order of many thousands of items without becoming unresponsive. A comparison of parallel coordinates visualisations with 100 records in 20 dimensions compared three imple- mentations: FluidDiagrams (WebGL), FluidDiagrams (Canvas 2D), and D3 (using SVG nodes). They achieved 62, 6, and 10 frames per second respectively. The FluidDiagrams (WebGL) implementation was able to render 1,000 records in 20 dimensions at 18 frames per second, compared to 1 and 6 respectively.
