Optical, Energetic and Exergetic Analyses of Parabolic Trough Collectors

引用

Chinese Physics Letters 2007年第7期24卷 1787-1790页

作者： OZTURK Murat, CICEK BEZiR nalan OZEK Nuri Department of Physics Science-Literature Faculty Siileyman Demirel University Isparta TUrkey

Parabolic trough collectors generate thermal energy from solar energy. Especially, they are very convenient for applications in high temperature solar power systems. To determine the design parameters, parabolic trough collectors must be analysed with optical analysis. In addition, thermodynamics （energy and exergy） analysis in the development of an energy efficient system must be achieved. Solar radiation passes through Earth＇s atmosphere until it reaches on Earth＇s surface and is focused from the parabolic trough collector to the tube receiver with a transparent insulated envelope. A11 of them constitute a complex mechanism. We investigate the geometry of parabolic trough reflector and characteristics of solar radiation to the reflecting surface through Earth＇s atmosphere, and calculate the collecting totM energy in the receiver. The parabolic trough collector, of which design parameters are given, is analysed in regard to the energy and exergy analysis considering the meteorological specification in May, June, July and August in 1sparta/TUrkey, and the results are presented.

Coexistence of Mirizzi syndrome with adenomyomatosis in the gallbladder:report of a case

引用

Hepatobiliary & Pancreatic Diseases International 2007年第4期6卷 438-441页

作者： Abdulkadir Bedirli Mustafa Kerem Hasan Bostanci Tarkan Karakan T. Tolga Sahin nalan Akyurek Author Affiliations:Department of General Surgery Department of Gastroenterology Department of Pathology Gazi University Medical FacultyAnkaraTurkey

BACKGROUND: Mirizzi syndrome is a rare complication of cholelithiasis. Adenomyomatosis is a common tumor-like lesion of the gallbladder. METHODS: A 52-year-old man was admitted to our hospital complaining of right hypochondriac pain and jaundice. Ultrasonography and computed tomography revealed stones in the gallbladder and dilation of the intrahepatic bile ducts. Magnetic resonance cholangiopancreatography revealed narrowing of the common bile duct caused by compression of the gallbladder. Laparotomy revealed type II Mirizzi syndrome. RESULTS: Partial cholecystectomy with a Roux-en-Y hepaticojejunostomy reconstruction was performed. Histologically, Rokitansky-Aschoff sinus proliferation, hypertrophy of smooth muscles, and fibrosis were seen in the gallbladder. A segmental type of adenomyornatosis of the gallbladder was diagnosed. CONCLUSIONS: The pathogenic link between the two peculiar entities is unclear. A possible explanation is considered that the pathogenesis of Mirizzi syndrome is resulted from chronic inflammation due to adenomyomatosis.

The Accounting Profession： A Descriptive Study of the Common and Code Law Countries

引用

Journal of Modern Accounting and Auditing 2012年第7期8卷 932-950页

作者： nalan Altintas Fatih Yilmaz Istanbul University Istanbul Turkey

The accounting profession does not have a long history. It is mainly evolved in the last 150 years in the modem sense. Many factors influence the development of accounting and there are many reasons why countries have developed different accounting systems. Among these factors, the relationship between the legal system and the accounting profession is considered worthy of examination. For this purpose, the accounting professions of selected countries are studied. This study clearly demonstrates that the accounting profession in a country has been significantly affected by the judicial system of that country. In addition, the accounting and auditing environment is divided into two separate professions in the code law countries, whereas in the common law countries the profession is mainly organized under one title. However, because of historical or cultural influences, exceptions do exist in countries like Japan, Bulgaria, and Greece.

An Improved Method for Automatic Retinal Blood Vessel Vascular Segmentation Using Gabor Filter

引用

Open Journal of Medical Imaging 2015年第4期5卷 204-213页

作者： nalan Karunanayake Nihal D. Kodikara Department of Electrical and Computer Engineering Sri Lanka Institute of Information Technology Malabe Sri Lanka Department of Computer Science University of Colombo School of Computing Colombo Sri Lanka

Early detection of Non-Proliferative Diabetic Retinopathy (NDPR) is currently a highly interested research area in biomedical imaging. Ophthalmologists discover NDPR by observing the configuration of the vessel vascular network deliberately. Therefore, a computerized automatic system for the segmentation of vessel system will be an assist for ophthalmologists in order to detect an early stage of retinopathy. In this research, region based retinal vascular segmentation approach is suggested. In the steps of processing, the illumination variation of the fundus image is adjusted by using the point operators. Then, the edge features of the vessels are enhanced by applying the Gabor Filter. Finally, the region growing method with automatic seed point selection is used to extract the vessel network from the image background. The experiments of the proposed algorithm are conducted on DRIVE dataset, which is an open access dataset. Results obtain an accuracy of 94.9% over the dataset that has been used.
