For enhancing image contrast, global histogram equalization uses the histogram information of the entire input image for designing its transformation function. However, such global approach is suitable for overall enhancement, and it fails to adapt with the local image brightness features. In this paper, we present an effective method for image contrast enhancement that combines local information and global information. In local enhancement, we get multiple intensity mapping functions from the recursive mean-separate histogram equalization method. According to intensity level, we map different transformation functions to the center sub-block and its neighboring sub-blocks. This method is combined with unsharp masking to enhance the local detail of the image. Experimental results show the effectiveness of the proposed method.

The objective of this research is to evaluate the performance of a system of systems optimization algorithm, namely, L4G-PCAO, in building energy systems. Since the test bed of this research is an office building with more than two hundred occupiers, the heating and cooling demands of the building must always be fully satisfied. Consequently, changes in the currently-installed control system cannot be made forthrightly. Therefore, fresh ideas like implementation of new control strategies or optimization algorithms should be firstly put to the test via dynamic simulation, which makes engineers capable of examining new control and optimization strategies. The performance should then be analyzed and evaluated before implementing in the use case. This paper presents a strategy for simulation-based implementation of L4G-PCAO in a building energy system and also evaluates its performance. The results show that it is not only possible to conserve energy by applying this newly-developed optimization algorithm to existing control systems, but also it can shift the usage of energy sources in a more environment-friendly direction.

Disaster-based failures can seriously disrupt any communication network, making its services unavailable. Such disruptions may be caused by natural disasters, technology-related failures, or malicious attacks, and they are observably increasing in number, intensity and scale. When network services that are a part of critical infrastructure become unavailable, commercial and/or societal problems are inevitable. The issue of limiting the impact of disaster-based failures needs to be urgently addressed due to the lack of suitable mechanisms deployed in the current networks. The COST CA15127 (RECODIS) Action will fill this gap by developing appropriate solutions to provide cost-efficient resilient communications in the presence of disaster-based disruptions considering both existing and emerging communication network architectures. It will be driven by researchers from academia and industry in strong cooperation with governmental bodies. In this paper, we highlight the objectives of RECODIS, its structure, as well as planned outcomes.

Femtocells are an efficient way of reducing infrastructure costs while providing better data rates and coverage. High penetration is expected in the upcoming ultra dense 5G networks, increasing the probability of femtocells' clusters. Strong resulting interference for nearby non-subscribed users will require interference mitigation techniques. In this paper we present a mechanism where multiple femtocells coordinate their transmission to serve multiple non-subscribed users through hybrid access. First, the spectrum allocation of non-subscribed users by femtocells is determined. Then, we introduce a power control algorithm that is based on two factors. The need for compensation for the subscribed users, due to reduced spectrum, and the effect that any change in power transmission will have on neighbouring femtocells. We evaluate the effectiveness of the algorithm through simulations on individual throughput and overall achieved capacity.

Small cells are expected to contribute to the targets of next generation mobile networks. Ultra dense networks through the form of heterogeneous structures of multiple RAT technologies and small cells present a flexible, economical way for better coverage and data rates. In this paper, we investigate particularly how femtocells may best utilize their available resources in order to increase their provided capacity when neighbouring femtocells are present. We propose a spectrum policy, according to which femtocell deployments are forming clusters and the femtocells adopt hybrid access policy versus users subscribed to other femtocells members of the same cluster. We also determine the spectrum allocation for non-subscribed users in the range of the femtocell. We evaluate the performance of the set up through simulations showing that the mechanism offers better overall capacity.

Ultra-dense and Distributed Antenna Systems (DAS) technology consist fundamental means for achieving the data rates and round-trip times promised by future mobile networks, because they promise to assure excellent indoor coverage and offer the potential to meet the target key performance indicators at a lower cost. In this paper, we study the techno-economic aspects of ultra-dense and DAS deployments. Apart from the presentation of their architectures and advantages, we present a techno-economic modeling of these deployment types. The defined models are used for the investigation of the upper technologies from an economic perspective and therefore, they provide an insight in the future financial and price aspects of these technologies by consisting a useful tool for the definition of financing and pricing policies towards an economically viable ultra-dense femtocell-based or DAS deployment. Finally, it is confirmed that the Total Cost of Ownership (TCO) is lower for the femtocells compared to the DAS.

Optical pulse wave propagation in nonlinear and dispersive medium is simulated by constrained interpolated profile (CIP) method. In one dimensional space with dispersion and nonlinearity, Gaussian envelope pulse modulated by optical carrier wave propagates successfully with physically reliable manner for typical small and large amplitudes. The spreading and compressing behavior for small and large input amplitudes are caused by trade-off between linear dispersion and nonlinear refractive index modulation of the medium.

In this paper, the Open Academic Courses project at the Eastern Macedonia and Thrace institute of technology is discussed and assessed. This project aims on the development of online courses with various types of educational content, such as e-books, podcasts, video-lectures etc. which are all open to the world. The open courses that were developed as well as the platforms used are assessed both in terms of users' perceptions and courses usage.
