Nowadays data communication is growing rapidly. Among them multimedia and Internet communications by wireless systems are the most popular. So the architecture of the wireless networks is varying based on that. In this paper we review UMTS based on connection to Internet. We review UMTS architecture and functionality of its layer 2 with focus on RLC, then its error recovery mechanisms and trans...

Object oriented methodology is becoming popular in the development of present day software. It is necessary to analyse architecture at the early stages of the development life cycle in order to avoid pitfalls in the quality of finished product. In the present work, a unitary system methodology for structural (architecture) modelling and analysis of Object-Oriented Systems (OOSs) is presented th...

This paper presents a simple digital approach for adaptive power-line (PL) or other periodic interference extraction. By means of two digital square (or sine) wave mixers, the real and imaginary parts of the interference are found, and the interference waveform is synthesized and finally subtracted. The described technique can be implemented in an open-loop architecture where the interference i...

Since early days, peer-to-peer (P2P) protocols have proven significant improvements over traditional client-server models. On the other hand, the Session Initiation Protocol (SIP) is a popular protocol for establishing multimedia sessions, and uses a client-server approach. P2PSIP is an architecture for deploying SIP services over a P2P network overlay, and thus leverages the limitations of cli...

Hun-Jeong Kang et al. 203 This paper presents a method and architecture to analyze streaming media and multimedia conferencing traffic. Our method is based on detecting the transport protocol and port numbers that are dynamically assigned during the setup between communicating parties. We then apply such information to analyze traffic generated by the most popular streaming media and multimedia...

This paper presents a hybrid dialog state tracker enhanced by trainable Spoken Language Understanding (SLU) for slotfilling dialog systems. Our architecture is inspired by previously proposed neuralnetwork-based belief-tracking systems. In addition we extended some parts of our modular architecture with differentiable rules to allow end-to-end training. We hypothesize that these rules allow our...

The application of artificial intelligence (AI) to various medical subfields has been a popular topic research in recent years. In particular, deep learning widely used and proven effective many cases. Topological data analysis (TDA)—a rising field at the intersection mathematics, statistics, computer science—offers new insights into data. this work, we develop novel architecture that call Topo...

Ludwig Mies van der Rohe is regarded as one of the pioneers modernist architecture. Rohe’s works in both architecture and products showed his own characteristics these appeared repeatedly different works. His design simple exquisite, gradually formed vocabulary style. The concise refined, elegant popular. This research uses Form Synth style analysis to analyze shaping rules, integrates them a f...

Participatory sensing, when a crowd of users collaborate to collect useful information, based applications are getting popular these days thanks to the proliferation of powerful mobile devices. The builtin sensors of smartphones offer an easy and handy way to monitor the environment and collect data which can serve as the basis of smart applications. However, the quick and flexible development ...

The hash algorithm forms the basis of many popular cryptographic protocols and it is therefore important to find throughput optimal implementations. Though there have been numerous published papers proposing high throughput architectures, none of them have claimed to be optimal. In this paper, we perform iteration bound analysis on the SHA2 family of hash algorithms. Using this technique, we ar...
