In this study, the effects nano-SiO2 and nano-Al2O3 on cement mortars were experimentally studied. The percentage of nano-powders were used as 1%, 3% and 5% into the material. Different types of analysis were used to nano-powder’s impact on the cement mortars.…

In this paper we presents an application of deep learning techniques to recognize handwritten source code characters. Although there are many works on the handwritten character recognition (HCR) problem, very few works have been done about the offline handwrit…

Deep learning is a machine learning sub-field that uses deep neural networks. Instead of customized algorithms for each study in this field, it is aimed to cover the wider data set of solutions based on learning the data. Deep learning is a promising approach …

Neural Network has been used in a number of scientific fields including medical diagnosis. It is clear that classification is one of the main challenges in any medical diagnosis. However, the drawbacks of conventional neural network classifier are summarized a…

Ball and beam system is an experimental set for control system design that the position of the ball on a beam is changed with respect to the reference direction by changing the angle of the beam. The PID controller is applied to this problem. The performance o…

İhtiyaç duyulan enerji talebinin büyük bir bölümü petrol, doğal gaz, kömür gibi fosil ve nükleer yakıtlardan elde edilmektedir. Elektrik tüketiminin sürekli artması, kullanılan kaynaklarının çoğunun fosil kökenli olması ve bu kaynakların elde edilme zorluğu dı…

The cell temperature of a photovoltaic (PV) module increases with increasing irradiation rate, and this increment adversely affects the output power or the electrical efficiency of the PV module. Therefore, in the present study, a series of experiments are p…

Yapılan bu çalışmada, Ankara ili merkezinde bulunan bir kampüsün bazı binaların elektrik ihtiyacının fotovoltaik sistemlerle karşılanılmasının istenmesi durumunda tasarlanacak sistemden üretilebilecek enerji miktarının ve sistemin performans oranın simülasyon …

The developments in internal combustion spark ignition (gasoline) engine technologies are in line with emission standards. The conversion systems which enable the use of LPG fuel in spark ignition (gasoline) engines renew themselves according to the developmen…

Otel işletmelerinde hizmet alan ve verenin insan olmasından dolayı etkin iletişim ve etkileşim önemlidir. Otel çalışanlarının kaliteli hizmet sunabilmeleri için psikolojik açıdan iyi oluş halleri önemli unsurlardan birisidir. Çalışanların hizmet odaklı çalış…

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 …

Experimental design methods used in optimization of engineering problems and processes in many industrial fields have been shown to be applicable in road superstructures within this study. Using the special purpose statistical experiment design program, opti…

The integration of increasing renewable energy-based energy production into the existing electricity grid has become of great importance. The biggest difficulty to integration into the power grid is variability and discontinuity of wind energy. To deal with th…

The importance of the service quality has increased because of the rapid development of the technology and globalization. In the global competition environment, teaching of the students that can provide the expectations of the society and the business world is…

Depending on the growing industry and population, energy needs are increasing day by day. In parallel, our external dependency on energy also increases. This issue made it necessary to use of renewable energy sources as much as possible. As an extension of eff…

This paper describes a laboratory application for the forecasting the dielectric properties, using an artificial neural network embedded in a microprocessor. The dielectric permittivity and loss factor of the insulation material were determined as a function o…

Building automation and control systems (BACs) allow plants in buildings to be controlled and managed, thus increasing the users' comfort and reducing the operation and maintenance costs. As far as the lighting services are concerned, control systems offer an …
