This paper deals with the analyticalstatistical method of one of the most used biometrics, the face recognition. The research project shows changes in face of ten different women, and emotional changes of one woman. The distances' changes of the chosen anthropological points were measured to obtain better understanding of programming requirements for better reliability of those systems. As the measurements were done entirely manually and processed by the spreadsheet program, it was also compared to some of the values obtained earlier by fully computerized method. To acquire comparable data, the same methodology of experimental calculation was used. Copyright © (2012) by the International Measurement Federation (IMEKO).

Wireless communication has now entered the second century of its use and has valuable merits of improving the quality of life of all mankind. Technologies for wireless and mobile communications are replaced every 2-3 years. The current version of the Protocol provides Internet access up to 40 Mbps and this version is expected to increase the bandwidth. The telecommunications sector leaves much to be desired in improving service quality. This paper presents the possibilities of implementation of WiMAX technology in the territory of Gjakova. Also, here are discussed some aspects of mobile network on calculating the budget link of the mobile network with WiMAX technology. Calculating the link budget, the radius of cell to a base station in urban areas is about 0.6 km. In the planning area and the frequency band of 3.5GHz, with channel width of 5 MHz TDD and spectrum 30MHz. The link margin used in this case is 133.5 dB. © 2012 International Journal of computer Science Issues.

Recently, verifiable secret sharing schemes have been proposed to keep participants from providing fake or illegal stego-images. However, the schemes do not consider the recovery mechanism when parts of the information in stego-images are lost or incidentally modified during the transmission process. This paper presents a novel verifiable and reversible secret sharing scheme based on Shamir's scheme, which can authenticate the shares in advance and then recover the inauthentic parts to reconstruct the original secret image. The experimental results provided positive results for the feasibility of the proposed scheme.

Topic-oriented understanding is to extract information from various language instances, which reflects the characteristics or trends of semantic information related to the topic via statistical analysis. The syntax analysis and modeling is the basis of such work. Traditional syntactic formalization approaches widely used in natural language understanding could not be simply applied to the text modeling in the context of topic-oriented understanding. In this paper, we review the information extraction mode, and summarize its inherent relationship with the "Subject- Predicate" syntactic structure in Aryan language. And we propose a syntactic element extraction model based on the "topic-description" structure, which contains six kinds of core elements, satisfying the desired requirement for topic-oriented understanding. This paper also describes the model composition, the theoretical framework of understanding process, the extraction method of syntactic components, and the prototype system of generating syntax diagrams. The proposed model is evaluated on the Reuters 21578 and SocialCom2009 data sets, and the results show that the recall and precision of syntactic component extraction are up to 93.9% and 88%, respectively, which further justifies the feasibility of generating syntactic component through the word dependencies. © 2012 Springer Science+Business Media.

作者： D. Stratakis A. Miaoudakis T. Yioultsis T. Xenos Department of Applied Informatics and Multimedia Technological Educational Institute of Crete Heraclion Greece Department of Electrical and Computer Engineering Aristotle University of Thessaloniki Thessaloniki Greece

Wireless networking technologies in recent years have witnessed important developments since the advantages benefit both data transmission service providers, and individuals or ordinary users. Ease of installation of a wireless network, led to the development of millions of Wi-Fi networks throughout the world. Nevertheless, Wi-Fi has certain drawbacks that inspired the implementation of a new technology called WiMAX. In 2003, the IEEE 802.16™ standard, also known as WiMAX (Worldwide Interoperability for Microwave Access) was adopted, in order to meet the requirements for broadband wireless access. The purpose of this paper is to study how the electromagnetic fields generated by WiMAX base stations can be evaluated in terms of exposure.

The paper presents Takagi-Sugeno fuzzy control solutions - PI(D) fuzzy controllers with input and output integration and 2-DOF fuzzy controllers - meant for speed and position control of Brushless Direct Current (BLDC) drives. Simplified models of BLDC drives are used in new controller design methodologies. These models are characterized by second-order linear dynamics with/without an integral component and generally with variable parameters and allow. The Takagi-Sugeno fuzzy control solutions are briefly characterized and some approaches regarding the controller designs are highlighted pointing out the simplicity of our solutions. Comparative studies based on digital simulation results are included to exemplify the efficiency of the proposed design methodologies. © 2012 IEEE.

A search is presented for dark matter pair production in association with a W or Z boson in pp collisions representing 20.3 fb−1 of integrated luminosity at s=8 TeV using data recorded with the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet with the jet mass consistent with a W or Z boson, and with large missing transverse momentum are analyzed. The data are consistent with the standard model expectations. Limits are set on the mass scale in effective field theories that describe the interaction of dark matter and standard model particles, and on the cross section of Higgs production and decay to invisible particles. In addition, cross section limits on the anomalous production of W or Z bosons with large missing transverse momentum are set in two fiducial regions.

A search for excited states of the Bc± meson is performed using 4.9 fb−1 of 7 TeV and 19.2 fb−1 of 8 TeV pp collision data collected by the ATLAS experiment at the LHC. A new state is observed through its hadronic transition to the ground state, with the latter detected in the decay Bc±→J/ψπ±. The state appears in the m(Bc±π+π−)−m(Bc±)−2m(π±) mass difference distribution with a significance of 5.2 standard deviations. The mass of the observed state is 6842±4±5 MeV, where the first error is statistical and the second is systematic. The mass and decay of this state are consistent with expectations for the second S-wave state of the Bc± meson, Bc±(2S).
