(2006) have proposed several procedures and a mathematical model on single-model (product) assembly line balancing (ALB) problem with parallel lines. In parallel ALB problem, the goal is to balance more than one assembly line together. In this paper, a network model for parallel ALB problem has been proposed and illustrated on a numerical example. This model is a new approach for parallel ALB and it provides a different point of view for interested researchers.

In such an environment, the countries are also obliged to keep up with the change and modify their organizational structures in accordance with the requirements of the age. In this century when the phenomenon of technology makes its presence felt, the use of information technologies by the states has become compulsory for both ensuring the international competition and increasing the efficiency of national services as well as providing the public services. In such a context, the states should switch to the e- government approach leaving their traditional one. The fact that e-government practices have been adopted within the public administration and new state understanding is essential for ensuring the efficiency with regard to providing public services to the citizens. Within this context, the concept of e-state is defined...

ANNs were considered to be an option in the evaluation of growth properties. The potential use of accurate forecasts in decision making and fisheries management are supported directly by the findings of the present study.

In this respect, Cyber Security studies have evolved to solve problems requiring large and complicated operations due to the speed of data transmission and the development of technological infrastructures. Deep Learning methods have given a great viewpoint to the problems that should be used in learning methods such as classification or clustering by processing large data. With Deep Learning methods, which are now used in many areas of Siberian Security, while the other machine learning methods have lower performances, higher performance rates are obtained and quality of problem solution is improved. In this study, some deep learning methods used and the usage areas in Cyber Security are presented as a compilation study. Editor: H. Kemal Ilter, Ankar...

The age of topmouth gudgeon caught from Hirfanli Dam Lake ranged between 1 to 5 years. The von Bertalanffy growth function growth coefficient k was 0.5 and asymptotic length L∞ was 91.3 mm fork length (FL). The weight-length relationship is given by the regression equation W = 0.01275334 × L3.0005 for all individual. Growth equations in length (mm) and weight (g) are: Lt = 91.3 [1–e–0.380 (t + 0.5)] and Wt = 10.36 [1–e–0.380 (t + 0.5)]3.0005 for all individual. Minimum and maximum size was 27 and 92 mm FL for all individuals. Here, we examine the growth properties (length and weight) of topmouth gudgeon by modern (artificial neural networks) and traditional approaches (Length weight Relations and von Bertalanffy growth model) in Hirfanli D...

Samplings were done between 2 July and 30 October in 2006 and 2007 with a random method. We present the relationships between total length (TL), carapace length (CL), chelae length (ChL), abdomen length (AL) and total weight (TW) for A. leptodactylus from Mogan Lake. Study was conducted in 112 individuals (14 female, 98 male). The research was found as 87.5 % male, 12.5 % female of crayfish thought investigation female and male ratios was of determined as to 0.14 /1.00. Avarage total length was 108.71 mm for female, 102.93 mm for male, average total weight was 28.64 g for female, 32.49 g for male. Length-weight relation equation was found for females W=0.0022 L2.01 for males W=0.00095 L2.23. The results obtained by artificial neural networks and length-weight relation equation are compared to those obtained by the...

Two-dimensional videos; It is used in multimedia content-based indexing, information acquisition, visual surveillance and distributed cross-camera surveillance systems, human tracking, traffic monitoring and similar applications. It is of great importance for the development of systems for national security by following a moving target within the scope of military applications. In this research, a more efficient solution is proposed in addition to the existing methods. Therefore, we present YOLO, a new approach to object detection for military applications.

Since fresh water resources in form of groundwaters which are the most available water resources ... more Since fresh water resources in form of groundwaters which are the most available water resources for human consumption are extremely limited and due to uncontrolled human activities are prone to contamination, it’s of a great importance to constantly monitor the quality of the ground fresh water resources to provide a sustainable drinking water for people as well as protecting the ecosystem. One tool for modeling the water quality of a basin is Water Quality Index (WQI). However, calculating WQI is complicated and time- consuming, therefore, today, scientists are being inclined to propose simpler ways for modeling the quality of the water resources such as machine learning algorithms. In this study the performance of four machine learning algorithms with ensemble learning approach were evaluated to propose a classification model (classifier) with highest performance. Moreover, to identify the most important water quality parameters in the classification process, three feature select...

The research group of the study was constituted of 426 students who were attending in the 1st, 2nd, 3rd, and 4th grade at a secondary school in the academic year of 2015-2016. The research done by using environmental attitude scale concluded that the secondary students have a positive attitude towards the environment. It was found that there was a meaningful difference according to gender, age group, father profession status, mother profession status. It was also concluded that students did not differ according to mother education level, father education level, grade level, family income level, and number of siblings variables. Similar evaluations were made with artificial neural networks. In this study, it has been shown that artificial neural networks can be used in the studies conducted in the field of education.

The development of information technology has sped up the importance of management information systems, which is an emerging discipline combining various aspects of informatics, information technology, and business management. Understanding the impact of information on today’s organizations requires technological and managerial views, which are both offered by management information systems. Business management is not only about generating greater returns and using new technologies for developing businesses to reach future goals. Business management also means generating better revenue performance if plans are diligently followed. It is part of business management to have an ear to the ground of global economic trends, changing environmental conditions and preferences, as well as the behavior of value chain partners. While, until now, business management and management informatio...
