With an estimated 50 billion internet-enabled devices deployed by 2020, the arrival of the Internet of Things (IoT) or Internet of Everything (IoE) raises many questions regarding the suitability and adaptability of current computer security standards to provide privacy, data integrity and end entity authentication between communicating peers. In this paper we present a new protocol which combines zero-knowledge proofs and key exchange mechanisms to provide secure and authenticated communication in static machine-to-machine (M2M) networks. This approach addresses all of the aforementioned issues while also being suitable for devices with limited computational resources and can be deployed in wireless sensor networks. While the protocol requires an a-priori knowledge about the network setup and structure, it guarantees perfect forward secrecy.

This paper concerns the effect of configuration of high voltage power cables on induced voltages in their metallic sheaths. One, two or three cables per phase and phase sequence of the cables are considered. Computing of the voltages was performed for a normal operation and in case of earth fault. Various ways of the sheaths bonding are considered as well. Shock hazard and voltage stress of non-metallic outer sheath of cables are evaluated. Favourable configurations of the power cable system are indicated.

The algorithm for object classification on multispectral/hyperspectral images based on the Dempster-Shafer evidence theory is represented. The algorithm allows detecting not only separate classes but also their composition, i.e. takes into account the “mixed” pixels inherent in the presence of medium spatial resolution images.

The Six Sigma quality management method is intended for decreasing defects in production organizations; that is for improving the quality of production processes. Production processes need support of relevant business data. In other words the requirement of production quality can be broadened to requirement for high quality business data. This paper addresses application of the Six Sigma principles for increasing quality of data managed within information systems.

In this paper we describe fast and easy graph visualization layout we developed. We called it radius degree layout (RDL). RDL can be used for static and also for dynamic (interactive) visualization. RDL is easy to implement in 2D and 3D visualization, it is CPU efficient, also for large graphs, and we can easily orientate in graph using it. In this paper we describe RDL philosophy, implementation, testing with examples, practical using and the enhanced version with modified force directed layout.

This paper deals with the problem of designing the optimal structure of a public service system. The problem can be often formulated as a p-median location problem. Solving the p-median location problem in the public service system design is NP-hard problem. Real instances of the problem are characterized by big number of possible service center locations, which can take the value of several hundreds or thousands. The optimal solution can be obtained by the universal IP solvers only for smaller instances of the problem. The universal IP solvers are very time-consuming and often fail when a large instance is solved. Our approach to the problem is based on the Erlenkotter procedure and the Lagrangean relaxation. The Erlenkotter procedure solves the uncapacitated facility location problem. Using the Lagrangean relaxation allow to solve the p-median location problem. The suggested approach finds the optimal solution in the most studied instances. The feasibility and the quality of the resulting solutions of the suggested approach depends on the convenient setting of the Lagrangean multiplier. The convenient value of the multiplier can be obtained by a bisection algorithm. The resulting multiplier cannot guarantee the determination of the optimal solution, but it ensures the lower bound and the near-to-optimal solution. If our approach does not obtain the optimal solution, then it improves the near-to-optimal solution by some heuristic. We designed some heuristics for improving the obtained solution and choose the best improving heuristic. The improving heuristics are verified on comparison the resulting solution obtained by the improving heuristics and the optimal solution obtained by the universal IP solver XPRESS-IVE in the computational time and the quality of solutions.

Energy Systems are rapidly evolving, driven by a combination of factors, including cost, efficiency, environmental impact and security-of-supply, while being facilitated by increased deregulation. This complexity is facilitated by the rollout of complex Information & Communications Technology (ICT) systems that will play a significant role in operating, managing, planning, and securing the energy infrastructure. SmartGrid is an umbrella term used to describe the broad scope of interdependent systems that make up this modernized grid. These systems cover the full life cycle of energy from generation to transmission, distribution, and consumption. SmartGrid through use of ICT enables bidirectional flows of energy between these component systems and uses two-way communication and control capabilities to maintain efficiency, availability, and robustness. SmartGrid will bring about significant economic and environmental benefits to consumers, organisations, and countries, all facilitated by ICT. This paper provides a high level overview of the role of ICT in SmartGrid, focusing on some of the key issues.

The primary purpose of this article is the analysis of data that come from 219 radon-mine workers who underwent cytogenetic analysis (or analyses) of peripheral blood lymphocytes. We focused on the connection between the cytogenetic analysis results (the occurrence of different types of chromosomal aberrations - chromatid and chromosome changes and breaks) and the occurrence of carcinoma. We also analyzed the influence of other explanatory variables, such as age, smoking, and the level of exposure to radon. We performed separate Cox analyses for the incidence of any type of cancer and for the incidence of lung cancer only as dependent variables. In the latter case, we found out that the only significant factors were the level of exposure to radon and the fact whether or not the subject ever smoked. As for the overall cancer incidence, we found two suitable models. Both models utilise age, smoking status, the level of exposure and the frequency of chromatid changes. In addition to these variables, the first model contains the frequency of chromatid breaks and the second model contains overall frequency of chromosomal aberrations. As the study was an expansion to the study of Šmerhovský et al. from 2002, we also compared our results with the results of this study. As for the overall incidence of cancer, the results were not markedly different from the aforementioned study. Regarding the lung cancer incidence, a significant association of chromosomal aberration frequency and chromatid breaks frequency had been found in the original study, while our findings showed that none of the aberrations were significant for the lung cancer incidence.
