Complex Event Processing - A Survey

V. Govindasamy and P. Thambidurai

Complex Event Processing (CEP) deals with generating event notifications by deriving complex events from primitive events. The primitive events are from multiple distributed sources. In this paper, we present a survey of the recent publications with respect to Complex Event Processing in Distributed Event Processing Systems. A comparative study of all the major approaches are listed and discussed. Major contribution of this paper is i)Identification eight trends in CEP systems in recent years ii) Detailed description of existing approach and iii) Comparative study of existing approaches.

Hybrid Network Coding Peer-to-Peer Content Distribution

Dinh Nguyen and Hidenori Nakazato

Network coding has been applied successfully in peer-to-peer systems to shorten the distribution time. Pieces of data, i.e. blocks, are combined, i.e. encoded, by the sending peers before being forwarded to other peers. Even though requiring all peers to encode might achieve shortest distribution time, it is not necessarily optimal in terms of computational resource consumption. Short finish time, in many cases, can be achieved with just a subset of carefully chosen peers. Peer-topeer systems, in addition, tend to be heterogeneous in which some peers, such as hand-held devices, would not have the required capacity to encode. We therefore envision a P2P system where some peers encode to improve distribution time and other peers, due to limited computational capacity or due to some system-wide optimization, do not encode. Such a system gives rise to a design problem which has never happened in both pure non-coding and full network coding-enabled P2P systems. We identify the problem and propose our solutions to address it. Simulation evaluation confirms robust performance of our proposed hybrid network coding peer-to-peer content distribution.

Mobile Search Engine Optimization (Mobile SEO): Optimizing Websites for Mobile Devices

M.S.Rawat and S.K. Dubey

This paper presents and discusses the approaches used in mobile search engine optimization (Mobile SEO). The search engines used for mobile devices are mobile optimized versions as bandwidth limitation, different mobile platforms and other factors come in to play. As a result search algorithms used by these search engines are different for mobile devices as compare to desktop systems. This paper provides a deep insight about mobile SEO through analysis and implementation of selected search engine optimization techniques that are revealed to achieve higher rankings in search results for a mobile website.

Applying a natural intelligence pattern in cognitive robots

N. Jafari, J. Jafari Amirbandi, A. Rahmani and M. Pedram

Human brain was always a mysterious subject to explore, as it has still got lots to be discovered, and a good topic to be studied in many aspects, by different branches of science. In other hand, one of the biggest concerns of the future generation of Artificial Intelligence (AI) is to build robots who can think like human. To achieve this AI engineers used the theories inspired by human intelligent, which were suggested by well-known psychologists, to improve the intelligence systems. To control this complicated system they can gain a lot of benefits from studying how human mind works. In this article, cognitive robots, which were equipped to a system that was built based on human brain s function, searched in a virtual environment and tried to survive for longer. To build the cognitive system for these robots, the psychoanalysis theory of Sigmund Freud (id, ego, and super-ego) was used. And at the end, the surviving period of cognitive robots and normal robots in similar environments were compared. The results of these simulations proved that cognitive robots had more chances of surviving.

Business Process: The Model and The Reality

P. Szmodics

This paper gives an overview about the business process management’s main perspectives. First it defines the differentiation between public and private value drivers then it assesses the difficulties in the process modeling. It shows the process compliance as the key of the practical success and gives some idea about its management. It also reveals the BPM as source of possible holistic risk in the society. In this paper the key elements of the future research of the author are introduced.

A Compact Priority based Architecture Designed and Simulated for Data Sharing based on Reconfigurable Computing

Bhavya Alankar and B K Kanaujia

Reconfigurable Computing devices are coming very strongly in the digital hardware systems due to the availability of ready to use resources, parallel logic operations and reconfigurable designs. The usage of Reconfigurable systems in real time domain is also a very fruitful proposition as the FPGA devices are coming with processing cores for Real Time data processing. This paper mainly focuses on the application of Reconfigurable Computing systems in the data sharing domain and in order to depict this application we have designed and simulated a priority based data sharing architecture through which we can interface two Processors, which in turn can intercommunicate with each other. The main advantage of this architecture is that it is highly compact, easy to use and designed using a modular approach so that it could be easily implemented on Reconfigurable hardware. All the different modules along with the complete architecture is simulated using modelsim 6.0 and synthesized using Xilinx 7.1(iSE).
