Review of modern approaches to risks evaluation is carried out. Analysis of software projects risks evaluation methods is performed. Analysis of sensitivity, scenarios method, simulation modeling, expert assessment are reviewed. Conclusions on importance of risks evaluation for "Software as a Service" software application systems at design stage are performed. It's proposed to perform software projects risks evaluation with expert assessment using by realization of corresponding information technology. </em></p> <p style="text-align: justify;"><em>Mathematically risks evaluation technology is realized by Delphi method and ranking. Term of confidence interval is used as stopover criterion in computational procedure of Delphi method with the goal of coherent expert opinion obtaining. Calculating procedure envisages initial expert data correction by expert opinions revision and correction of expert group personnel. Consistency of expert opinions in mathematical technology on ranking method is checking with using of Kendall concordance coefficient, and its significance is evaluating on the basis of Pearson criterion. Presented mathematical apparatus formalizes solution of risks evaluation problem. </em></p> <p style="text-align: justify;"><em>Methods of software projects risks evaluation and theirs mathematical technologies requires a big amount of calculating operations. Information support increases the rate and precision of such operations, ensures initial data and obtained results accumulation. Information support of software projects risks evaluation is realized as software application system. At development of software application system functional and nonfunctional requirements, database model and its structure were defined. Principles of object oriented analysis, data modeling, modern design patterns, CASE software tools were used. </em></p> <p style="text-align: justify;"><em>It's proposed to realize software application system of information technology in accordance with client-server architecture, dedicated application server with distributed access rights with using of IDE NetBeans by PHP means under MySQL control.

Global energy consumption is expected to increase by 28% by 2040. High economic growth rates of developing countries increase their energy consumption. The changing geographical and economic balances in energy reveal the necessity of producing long-term solutions to the changes in energy markets. Energy policies, green energy and new technologies are emerging as priority issues in the energy market. In the case of predictions, renewable energy will stand out as the fastest growing energy source in the world. </em><em>The solar energy sector is considered as one of the most important investment in renewable energy resources invested together with government incentives. Intelligent technologies, including the connection of objects to the Internet, storage of big data, cloud computing systems, artificial intelligence (AI) development, virtual reality, and other forms of advanced communication, fundamentally change the operation of businesses and societies. </em><em>Digitalization of solar energy is an important issue for especially smart cities.</em></p> Nevin TASALTIN ##submission.copyrightStatement## Thu, 31 Jan 2019 00:00:00 +0300 RULE OF THUMB TO DETERMINE THE LOCATION OF WI-FI MODULE ON PLASTIC OR METAL CHASSIS <p style="text-align: justify;"><em>In this study, a general rule of thumb was developed for an easier and more robust product configuration management containing more than one Wi-Fi modules. In the study, a television chassis is being used for two different models having different Wi-Fi modules in them. From manufacturing perspective, managing the product configuration as simple as it can improve the manufacturing costs drastically. Two Wi-Fi modules having different antenna characteristics will perform differently based on their locations on the chassis. Based on the distance of the antenna to the closest material of the chassis effects antenna characteristics of both Wi-Fi modules. We obtained a common minimum distance that does not disrupts the antenna performance of both Wi-Fi modules to out of Wi-Fi spectrum. For the particular case in this study, we obtained a safe distance which keeps the voltage standing wave ratio of the antennas of both Wi-Fi modules under two over Wi-Fi frequency spectrum.</em></p> Alper ÖZEL, Meriç DÖNER ##submission.copyrightStatement## Thu, 31 Jan 2019 00:00:00 +0300 ORGAN DONATION AWARENESS <p style="text-align: justify;"><em>Organ transplantation is a medical procedure which a healthy organ is removed from the living or cadaver donor to be transplanted into the recipient whose related organ is no more functioning properly. There are two types of organ transplantation: living-donor and cadaver-donor transplantation. After the donation, related organs are taken from the patient following the brain death in the ICU and transplanted to the recipient. Organs can be used only when the brain death is confirmed and declared in the ICU. Brain death is the irreversible state of loss in the brain functions. According to the article 14 of the law No 2238, when a patient is officially brain-dead, the organs or tissues can be taken with the consent of their spouse, children of age, mother/father, siblings in order or an acquaintance of any of them if the rest is not present. Organ donation is when an individual gives their consent by documentation, with free will, and allow their tissues and organs to be donated for the treatment of other patients after the end of their life medically. According to the law no 2238, any citizen who is mentally healthy and above 18 years of age, can donate their organs and obtain an organ donation card. Organ transplantation is a very serious medical issue in Turkey as it is in other countries and the donation rates should be increased by informing the public and getting more participation. Success in organ transplantation can be obtained by a higher number of organ donations.</em></p> <p style="text-align: justify;">&nbsp;</p> Cabir ALAN, Hasan Anıl KURT ##submission.copyrightStatement## Thu, 31 Jan 2019 00:00:00 +0300 BIODIVERSITY AND DIET OF COCCINELLIDAE ON CITRUS IN METIDJA (ALGERIA) <p style="text-align: justify;"><em>Biological control is a viable alternative to the use of chemical pesticides that are harmful to the environment. From this perspective, this work aims to make an inventory of Coccinellidae and to classify them according to their diet. Sampling by yellow sticky plates is carried out each week from 23 April to 24 July 2014 at the Eastern Metidja very important citrus region in Algeria. A total of 16 ladybug species are sampled in four citrus species, orange, lemon, clementine and pomelo. It is the Coccidiphagous that are the richest with a total of 7 species, followed by the aphidophagous with 5 species and&nbsp; mycophagous with the two species. Finally found the aleurodiphagous and acariphagous, with a single species for each group. With regard to relative abundance, a total of 467 individuals coccinellidae were captured, of which the species Clitostethus arcuatus (ladybug aleurodiphagous) alone counted 285 individuals, that is 61.29%. </em></p> Nabila BOUBEKKA, Samia HACINI ##submission.copyrightStatement## Thu, 31 Jan 2019 00:00:00 +0300 RARE AND ENDEMIC TAXA OF LAMIACEAE IN TURKEY AND THEIR THREAT CATEGORIES <p style="text-align: justify;"><em>Lamiaceae (Labiatae) is the third largest family in Turkey.
