One of the key subsystems from point of view of security of the complex IoT system is the smart business center (SB?) system. Some problems the design and operation of the SBC system are analyzed. When analysis of safety of the IoT system must take into account the reliability and security of the system at several levels: The level of sensors, the level of communication (communication lines, router, switch), the server level as the control device of components of the network, the level of the entire SBC subsystem. General architecture of network of the SB? is described. Reliability and security of key SB? hardwareand software manufacturers are analysed. In particular, security issue for SB? routers is considered. Shown the Markov model, which takes into account the technical conditions of typical network components of the SBC with the presence of software vulnerabilities when exposed to hacker attacks. On this model's basis it is possible to conduct further researches directed for improving the reliability operation and safety of IoT. ©2016 IEEE.

In the quest to achieve scalable quantum information processing technologies, gradient-based optimal control algorithms (e.g., GRAPE) are broadly used for implementing high-precision quantum gates, but their performance is often hindered by deterministic or random errors in the system model and the control electronics. In this paper, we show that GRAPE can be taught to be more effective by jointly learning from the design model and the experimental data obtained from process tomography. The resulting data-driven gradient optimization algorithm (d-GRAPE) can in principle correct all deterministic gate errors, with a mild efficiency loss. The d-GRAPE algorithm may become more powerful with broadband controls that involve a large number of control parameters, while other algorithms usually slow down due to the increased size of the search space. These advantages are demonstrated by simulating the implementation of a two-qubit CNOT gate. Copyright © 2017, The Authors. All rights reserved.

This paper proposes a general robust active noise control (RANC) framework for removing power line interference (PLI) from the Electroencephalogram (EEG) signals when both reference and primary signals are contaminated by spike noise. It is obtained by exploiting the robust property of M-estimation function against impulses. According to this new framework, two commonly used methods, namely, least mean squares (LMS) and normalized least mean squares (NLMS), are extended in parallel to least mean M-estimate (LMM) and normalized least mean M-estimate (NLMM), respectively. Experimental results based on the benchmark MIT-BIH Polysomnographic Database show the sufficient capability of our methods for cancelling PLI in EEG signals with noisy observations and excellent performance for rejecting spikes existing in PLI and EEG signals.

In this paper, four elements fractal shape antenna with non-uniform annular ring Photonic Band Gap (PBG) etched in the ground is presented. The impact of the PBG structure in removing the undesired harmonic frequencies of the proposed antenna is demonstrated. The proposed antenna is designed, fabricated and tested. The results show that the designed antenna is capable of resonating at three different frequencies of 915 MHz, 1.8 GHz and 2.45 GHz with high-efficiency performance in terms of return loss, gain and radiation pattern characteristics with compact size. Good agreement between the measured and the simulated results is observed.

The purpose of this paper is to assess the economic impact following as a result of the conversion of conventional stations to cogeneration plants connected to a system for distributing heat and refrigeration. The analysis will be carried out through a financial evaluation in order to assess yearly variations of the whole scheme expenditure. In particular, yearly capital and operating costs of supplying cold and heat to urban areas that represent weather conditions in northern, central, and southern Europe were studied. In the base case scenario, today conditions are represented; they will be compared with alternative scenarios in which existing conventional thermal power stations will be converted into cogeneration plants. This research work contributes to the pool of existing knowledge by giving a (so far not addressed) weather centered system perspective. From the conducted evaluation, it was found that, in the case of deciding to convert the studied conventional thermal plants into cogeneration plants, investing in the necessary infrastructure associated means that yearly expenses for the power plants located in Oldenburg-Wilhelmshaven, Bristol, and Cartagena would decrease by 215, 89, and 192 million euros respectively, making this technology a highly attractive option from economic, energetic, and environmental perspectives.

Nowadays wind turbine rotors are usually employed with pitch control mechanisms to avoid deep stall conditions. Despite that, wind turbines often operate under pitch fault situation causing massive flow separation to occur. Pure Blade Element Momentum (BEM) approaches are not designed for this situation and inaccurate load predictions are already expected. In the present studies, BEM predictions are improved through the inclusion of a stall delay model for a wind turbine rotor operating under pitch fault situation of -2.3° towards stall. The accuracy of the stall delay model is assessed by comparing the results with available Computational Fluid Dynamics (CFD) simulations data.
