An economic comparison and evaluation of two geothermal district heating systems for advanced exergoeconomic analysis
Keçebaş, Pınar; Gökgedik, Harun; Alkan, Mehmet Ali; Keçebaş, Ali (Pergamon-Elsevier Science Ltd, 2014)This paper refers to an economic comparison and evaluation of two geothermal district heating systems (GDHSs) under same reference state condition and mechanic/economic parameters by using an advanced exergoeconomic analysis. ... -
Educational and consciousness-raising movements for renewable energy in Turkey
Keçebaş, Ali; Alkan, Mehmet Ali (Sila Science, 2009)Turkey has some difficulties in meeting its energy need due to rapid industrialization and population growth. It is necessary to educate and raise the consciousness level of the future generations to use the renewable ... -
EFFECTS OF CUTTING PARAMETERS AND TOOL-PATH STRATEGIES ON TOOL ACCELERATION IN BALL-END MILLING
Gök, Arif; Gök, Kadir; Bilgin, Mehmet Burak; Alkan, Mehmet Ali (Inst Za Kovinske Materiale I in Tehnologie, 2017)The determination of the cutting-parameter values that cause increases in vibration values is important to minimize the errors that can occur. Thus, the first aim of this study was to investigate the optimum cutting-parameter ... -
Energetic and economic evaluations of geothermal district heating systems by using ANN
Kecebas, Ali; Alkan, Mehmet Ali; Yabanova, Ismail; Yumurtaci, Mehmet (Elsevier Sci Ltd, 2013)This paper proposes an artificial neural network (ANN) technique as a new approach to evaluate the energy input, losses, output, efficiency, and economic optimization of a geothermal district heating system (GDHS). By using ... -
