New technologies are developing very faster than before and also technologies changed rapidly needs of people according to the use of technology. To understand the meaning of the benefits that renewable energy can bring we must firstly establish our understanding of the concept. The future of the developed and developing countries in the world depends on the availability and transport of energy. It...
Critical infrastructures conduct important services for the countries where they are via help of SCADA (Supervisory Control and Data Acquisition) systems/networks. Even little hitches in these services cause severe economic and environmental damage to countries where these systems are. When the SCADA systems used at the first time, unsecured communication protocols were not considered as a threat...
The traffic has been transformed into the difficult structure in points of designing and managing by the reason of increasing number of vehicle. This situation has discovered road accidents problem, influenced public health and country economy and done the studies on solution of the problem. Large calibrated data agglomerations have increased by the reasons of the technological improvements and data...
In Turkey, there are many exams for transition to a higher education institution. These exams are all stages of life and have a great importance in the lives of students.As the severity rating of the exam, particularly students, parents and teachers are affected and exams create anxiety for students.Examination results are very important in shaping the lives of future students. Therefore, in this...
In order to ensure that digital evidence is collected, preserved, examined, or transferred in a manner safeguarding the accuracy and reliability of the evidence, law enforcement and digital forensic units must establish and maintain an effective quality assurance system. The very first part of this system is standard operating procedures (SOP's) and/or models, conforming chain of custody requirements,...
Data mining is a process of getting out useful information from data stacks. One of the most common application areas is to use classification of algorithms that estimate the future events by past experiences. In this context, in order to predict future events, a data warehouse is created by using the background of students which includes demographic, personal, school, and course information of students...
In this paper, an experimental application focused on energy quality observation is developed. The required parameters are obtained from the system by the designed electronical measurement cards and then transferred to the computer. As the controller a Data Acquisition card is used and also a user-friendly web interface is prepared for computing and managing all of the information to show power quality,...
In this study, parallel connection of separate voltage sources has been realized using cuk converters. For this aim, output voltages of converters are measured continuously and then fixed to a reference value. The PWM signals which are required to control the converters and to sense the current and voltage signals are generated by an FPGA. Since the FPGA has parallel processing feature, voltage and...
