Plants encounter a variety of environmental stress factors that affect plant growth, fruit yield and quality. Stress factors cause physiological dysfunctions, ion imbalance, depression in photosynthesis, leading to growth reduction and decrease in fruit qual…
Teknoloji günümüzde her alanda kullanılmaktadır. İnsansız Hava Araçlarının da çeşitli sektörlerde (İHA) kullanımı gün geçtikçe artmaktadır. İlk zamanlarda askeri amaçlar için kullanılan İHA teknolojisi, günümüzde jeodezi, tarım, meteroloji, iletişim, acil du…
In this study, it is aimed to design C pattern array microstrip antenna for C Band (4 to 8 GHz), X Band (8 to 12 GHz) and Ku Band (12 GHz to 18 GHz). The proposed geometry was fed by coaxial probe. Optimum antenna was designed with Artificial Neural Network …
In many engineering applications such as aerospace, automotive and telecommunications, icing leads to mechanical and socio-economic problems such as efficiency reduction, decreased power transmission, security threat, material damage and energy waste. Theref…
The importance of manufacturing industry, which has the largest production value and employment volume, is increasing day by day in economy. Furniture industry with rising production value and employment levels has the potential among large sectors of Turkey. …
To follow the class attendance of the students is a challenging and time consuming process in terms of lecturer. Followup of class attendance at universities is done by circulating the attendance sheet in class. The number and signature of each student is got.…
Bu çalışma ile bireylerin renk tercihlerinin aldıkları eğitime göre değişip değişmediği araştırılmaktadır. Çalışmada çevresel imajı oluşturan ‘renk’ kavramı bağımlı değişken olarak, bireylerin eğitim durumu ise bağımsız değişken olarak ele alınmış ve bu iki …
About 90% of world trade in transportation of goods is conducted via maritime transportation. An important operation area of maritime cargo transportation is ports. It is necessary to keep these ports secure where information and communication technologies a…
Ricania japonica (Melichar, 1898) (Homoptera: Ricaniidaee) is a harmful insect species. It is spreading in the Eastern Black Sea coastline from Artvin- Kemalpaşa to Ordu - Perşembe. Since 2006, R.japonica has been continuing to suffer the loss of all vegetab…
Bu çalışmada, DIN 1.2738 çeliği CVD kaplı karbür kesici takımlarla kuru kesme şartlarında tornalama deneylerine tabi tutulmuştur. Kesme parametreleri; üç farklı kesme hızı (150, 200, 250 m/dak), üç farklı ilerleme hızı (0,1, 0,15, 0,20 mm/dev) ve sabit kesme…
Trend analysis of precipitation play a significant role in the efficient water resources management, especially in arid and semi-arid regions. In this study, 48 years-long (1970-2017) annual precipitation data monitored at nine selected stations (Mardin, Adı…
Evaluation of rock engineering properties is a significant phenomenon for mining, civil and geotechnical engineering disciplines. Uniaxial compressive strength is one of the most important engineering parameters and it is used to characterize rocks from the …
Oscillation theory for the solutions of Sturm-Liouville problems is one of the traditional trends in the qualitative theory of difierential equations. Its main goal is to establish su–cient conditions for the existence of oscillating solutions, to investigate…
Because of the great earthquakes that have occured for centuries, many loss of lifes and goods have been experienced all over the world. Our country is located on active seismic zone. Many great earthquakes have also occurred in our country and have caused man…
In this paper, three different types of coordinate transformations that are frequently used in geodetic applications are given the details of their application with evolutionary algorithms. Similarity (Helmert), Affin and Projective transformation models commo…
Many well-known material structures, such as metals, ceramics or polymers, cannot meet all the technological demands. For this reason, there is ongoing research into new materials with advanced features. A composite material is consisting of at least two phase…
The health need is undoubtedly an indispensable necessity for human life. When the literature is examined, it is seen that various health monitoring systems are developed by helping to meet the health need with technological improvements. Some of these studies…
Ceramic materials are characterized by outstanding hardness, extreme compressive strength and elastic modulus, wear resistance, thermal shock resistance, chemical stability and high temperature properties. Therefore they have potential materials to be use at i…
Size of damage caused by an earthquake depends on the amount of energy released by the current stress accumulation of the active faults and the change over time. Stress accumulation on a fault occurs in two types. These are 1) the long-term tectonic movements …
