In this paper, we present a deep learning approach for learning for multiple remote sensing sources. The method starts by eliminating the distribution shift between the different sources and the target dataset using an adversarial learning approach based on min-max entropy optimization. After convergence, the results are aggregated using an average fusion layer. As pre-trained CNN we use in the work the recent state-of-the-art EfficientNet models. In the experiments, we assess the method on four remote sensing datasets acquired over different locations of the earth’s surface and are labeled by different experts. The obtained results confirm the promising capability of the proposed method.

Goal of this paper is to investigate the potential of modified differential evolution (MDE) algorithm, to find solution for optimal power flow (OPF) problem of power systems incorporating flexible ac transmission system (FACTS) devices. The optimization problem of the present work is formulated with four different objective functions viz., (a) fuel cost minimization, (b) power transmission losses minimization, (c) emission reduction and (d) minimization of combined economic and environmental cost. In this context, two FACTS devices, namely, thyristor controlled phase shifter (TCPS) and thyristor controlled series capacitor (TCSC) are integrating at predefined locations on the standard IEEE-57 bus test system. The results demonstrate the potential of the proposed approach and show its effectiveness and robustness to solve the OPF problem for the test systems considered.

In recent years, the Energy Storage Systems field for all electric vehicle applications has attracted many researchers and academic institutions. The main challenge concerns the design in terms of weight, volume, and increasing as possible the hybrid source lifetime. Therefore, increasing the vehicle drive range is very important parameter to facilitate their commercialization.Several storage components can be used to achieve the needed performances as super capacitor, batteries and fuel cell systems. However, fuel cells are energetic components where it is needed to add a powerful element to ensure the power peaks during acceleration and deceleration phases. This paper deals with, a comparative study between fuel cell and battery based power trains for lightweight electric vehicles. A developed algorithm is used to obtain the optimal sizes and constraints of different Energy Storage Systems (ESS) based on fuel cells, batteries and supercapacitors. The comparison between the several systems is based on their costs, volumes, weights and constraints applied to cells. First, to confirm the hybridization benefits we present a comparative study between single and hybrid ESSs according to the desired drive range in terms of energy consumption, weight and cost. Furthermore, in the objective to improve the hybrid ESS performances, different technologies batteries and supercapacitors are tested and their performances will be evaluated. Simulation results show that the desired range influences the choice of storage system technologies for the hybrid enrgy storage system. This results confirm also the interest of hybrid storage system composed with fuel cells and battery for high drive range (>400km).

Software companies’ acceptance to adopt security practices during the software development life cycle differs from one company to another. It can be said that one of the reasons for these differences is the varied characteristics of each company, such as its size, resources, and field. This paper aims to study the characteristics of companies that affect the adoption of security practices during software development. We studied eight company characteristics, some of which are classified as primary characteristics, including company size, type of developed software, and type of company. Meanwhile, the remaining five characteristics are classified as secondary characteristics, including company field, years of experience, methodology, presence of security experts, and approach to adopting security practices. A survey method was designed to find company characteristics that impact security adoption during software development. Results show that large companies, especially generic companies, adoption security practices more than other types of companies.

One of most relevant cyberattacks are DDoS–attacks, purpose of which is failure (denial) of service by server. Its successful implementation limits, or ensures the inaccessibility of information system resources located on server, to all its users. The consequences of this attack can result in financial losses for IS owner, as well as failure of hardware as a whole. Practical implementation of the method for detecting DDoS attacks at L7 level of OSI model – HTTP Flood if offered. This method is based on mathematical model that reproduces the interaction of clients with the server. It takes into account the individual characteristics of parameters describing operation of network and server, which affects to the possibility of more effective attack detection. Authors’ development offers the software implementation of this procedure as extension module to reflect large number of non– valid requests from attacking side of HTTP_Flood_reject. Such solution realization is aimed to protect critical resources of commercial organizations and natural persons to provide service from DDos–type attacks.

Cryptography is the science that concern of protecting data by transforming its comprehensible form into incomprehensible one. This study aims to compare between Advanced Encryption Standard (AES) and Rivest-Shamir-Adleman (RSA) encryption algorithms in image encryption using MATLAB. The comparison is done in the terms of testing image encryption quality for each algorithm. In addition, analyzing the histogram and correlation results. The results showed that AES algorithm has a better image encryption quality with a more convergent columns in the histogram. Moreover, AES algorithm correlation coefficient tends to be closer to the zero, thus a stronger correlation. Generally, the outcomes of this study showed that the AES algorithm is better than RSA algorithm in image encryption.1

In June 2018, it became legal for women to drive in Saudi. Since then, driving schools cannot keep up with demand for driver training and licensing. Applicants may take several months to start their classes at a school, most of which are located in major cities such as Riyadh. Official driving schools for women in Saudi Arabia are noticeably fewer than those for men and those schools cannot cope with the high demand, thus increasing the waiting time to enrol. The proposed Driving Coach Finder application aims to provide a communication space for Saudi women learning to drive and trainers or coaches. Further, creative features aim to make the experience of driving education enjoyable and support Saudi women willing to learn to drive but who cannot access driving schools. A participatory design process was undertaken with Saudi women who had had no driving experience. During the focus group, participants revealed several challenges and needs in order to learn how to drive; their responses have provided a powerful guidance for the design of proposed application. Saudi women will be able to find, review and share details of female driving instructors and locations in which to practise driving. Driving Coach Finder will assist in the creation of a marketplace to help find a private professional driving instructor and, at the same time, consider the specificity of society local culture and the needs of users. Helping to empower women wishing to obtain a driver’s licence will contribute to the country’s high economic and social growth. Further, Driving Coach Finder is expected to aid the generation of employment opportunities for women.
