CHARACTERIZATIONS OF SOME ASSOCIATED AND SPECIAL CURVES TO TYPE-2 BISHOP FRAME IN E^3 Yılmaz, Süha In this paper, we investigate associated curves according to type-2 Bishop frame in E^3. In addition, necessary and sufficient conditions for a curve to be a regular one are studied to the mentioned frame. Finally we give characterization of the are length of spherical indicatrice and inclined curve using harmonic curvature. DergiPark: 169854; klujes

THE ROLE OF HYBRID POWER SYSTEMS TO CREATE SELF-SUSTAINING SMART HOMES FOR THE ELDERLY AND DISABLED Dursun, Bahtiyar; Tuna, Gürkan; Tuna, Ayşe With the increase in the number of the elderly and due to the disabled’ demand for independent living, there is significant interest in smart home technologies which can assist the elderly and disabled to continue living at home with independence and safety. The feasibility and effectiveness of smart home technologies for promoting independence, health, and quality of life have been proved in the literature.  In recent years, there is increasing interest from care providers to provide caregiving services for the elderly and disabled in their home environments instead of caring them in assisted-living centres due to a number of reasons including costs. Since caregiving services are provided at specific times, a few times a day or week, smart home technologies can help care providers deploy services which trigger alerts when urgent situations occur. However, due to the cost of caregiving services, maintenance costs of smart home systems, and increasing electric energy consumption, generating electricity from renewable energy sources can play an important role for this objective. In this study, we present an environmentally friendly hybrid power system which automatically chooses its energy source(s) without any user input and give the results of simulation study performed using Homer software. The simulation study proves that the proposed hybrid power system can easily generate electricity required by a smart home.; With the increase in the number of the elderly and due to the disabled’ demand for independent living, there is significant interest in smart home technologies which can assist the elderly and disabled to continue living at home with independence and safety.

GÜÇ TRANSFORMATÖRLERİNİN YILDIRIM DARBE ANALİZLERİNİN ANSYS@MAXWELL-3D İLE GERÇEKLEŞTİRİLMESİ Özüpak, Yıldırım; Mamiş, Mehmet Salih; Göktaş, Taner; Arkan, Müslüm Transformatörlerdeani olarak meydana gelen yüksek gerilim ve akımlara karşı transformatörünmekanik dayanımının tahmini, transformatörün hem tasarım aşaması hem de ömrüiçin çok önemlidir. Transformatörlerin dayanımının yıldırım darbelerine karşı sağlanabilmesiiçin tasarım aşamasında aşırı gerilimlere maruz kalan bölgelerinin bilinmesiönemlidir. Bu çalışmada, tasarlanan güç transformatörünün, hem normal çalışmakoşullarında hem de yıldırım darbesi durumundaki elektromanyetik akı değerlerive transformatörün sargılarında meydana gelen elektromanyetik kuvvetler analizedilmiştir. Sonlu Elemanlar Yöntemi'ne (SEY) dayanan ANSYS@Maxwell-3D ile transformatörün3D simülasyon modeli tasarlanıp analizler gerçekleştirilmiştir. Tasarlananmodel ile transformatörün hem normal çalışma koşullarındaki analizleri hemdeyıldırım darbesine maruz kaldığı durumdaki analizleri gerçekleştirlmiştir.Ayrıca, her iki çalışma koşulu için elektromanyetik akı ve elektromanyetikkuvvetler hesaplanmıştır.  Bu sayede, nüvedekimanyetik akı yoğunluğunun dağılımı, sorunlu ve mekanik dayanımın az olduğubölgeler tespit edilmiştir.  DergiPark: 571086; klujes

ON CHARACTERIZATIONS OF SOME SPECIAL CURVES OF SPACELIKE CURVES ACCORDING TO THE TYPE-2 BISHOP FRAME IN MINKOWSKI 3-SPACE Ünlütürk, Yasin In this paper, first we give a characterization of spacelike inclined curves according to the type-2 Bishop frame in Minkowski 3-space, and then define rectifying curves of  spacelike curves according to the type-2 Bishop frame in Minkowski 3-space as their position vectors always lie in the orthogonal complement  of their vector field . Moreover we characterize Bertrand curves in the same space via the new frame. In particular, we study Mannheim partner curves according to type-2 Bishop frame in  and express such curves in terms of their curvature functions. DergiPark: 169855; klujes
