This trial study was conducted to determine classifications for planimetric design efficiency of sample public hospitals in Turkey by developing a fuzzy logic algorithm. Utilizing primary areas and circulation areas from nursing unit floor plans, the study employed triangular membership functions for the fuzzy subsets; Mamdani rule system; min operation for finding rule firing strength; max composition; and 'centroid' method for defuzzification. The input variables -primary areas per bed and circulation areas per bed- were fuzzified in this model. The relations between input variables and output variable of design efficiency were displayed as a result of fuzzy rules. To test existing nursing unit floors, efficiency output values were obtained and efficiency classes were constructed by this model in accordance with general norms, guidelines and previous studies. The classification of efficiency was resulted satisfactorily in terms of comparing hospitals. Of the fifteen hospital floor plans tested in the model, six were in a class of low efficiency, other nine were in a class of medium one. None of them were in overall agreement with the spatial requirements in regard to standards and current recommendations. The utility of this model is in the capability to indicate boundaries of efficiency classes. Hospital designers and managers may obtain feedback information from evaluations and comparisons of existing buildings. Consequently, they may benefit from this model in decision making processes.

Assessment of convention centers from users’ perspective: application of importance-performance analysis Pembegül, Tuğba; Tanyer, Ali Murat; Restoration in Department of Architecture (2009) This study firstly aims to identify facility features of the convention centers and then propose a method in order to identify users’ priorities and evaluate what extent these were provided by the convention centre. Data has been collected using self-administered questionnaires from three group of users; attendees, employees and meeting planners. The study has been conducted in İstanbul Lütfi Kırdar Convention and Exhibition Center as a case, because of being the most remarkable convention center of Turkey....
Robust estimation and hypothesis testing under short-tailedness and inliers Akkaya, Ayşen (Springer Science and Business Media LLC, 2005-06-01) Estimation and hypothesis testing based on normal samples censored in the middle are developed and shown to be remarkably efficient and robust to symmetric short-tailed distributions and to inliers in a sample. This negates the perception that sample mean and variance are the best robust estimators in such situations (Tiku, 1980; Dunnett, 1982).
A novel approach for small sample size family-based association studies: sequential tests İlk Dağ, Özlem; Dungul, Dilay Ciglidag; ÖZDAĞ, Hilal; İLK, HAKKI GÖKHAN (Springer Science and Business Media LLC, 2011-08-01) In this paper, we propose a sequential probability ratio test (SPRT) to overcome the problem of limited samples in studies related to complex genetic diseases. The results of this novel approach are compared with the ones obtained from the traditional transmission disequilibrium test (TDT) on simulated data. Although TDT classifies single-nucleotide polymorphisms (SNPs) to only two groups (SNPs associated with the disease and the others), SPRT has the flexibility of assigning SNPs to a third group, that is,...
Predicting the outcome of construction litigation using neural networks Arditi, David; Oksay, Fatih E.; Tokdemir, Onur Behzat (1998-01-01) In this study, neural networks were used to predict the outcome of construction litigation. Disagreements between the owner and the contractor can arise from such considerations as interpretation of the contract, changes made by the owner, differing site conditions, acceleration and suspension of work, and so forth. When there are disagreements between the contractor and the owner, the result is the inefficient use of resources and higher costs for both the owner and the contractor, as well as damage to the...
Design of a new equipment for sesame seed dehulling Güngör, Uğraş; Esin, Ali; Department of Food Engineering (2004) In this study, new methods and processing equipments for sesame dehulling were investigated. First, water absorption of sesame seed was studied at 20, 30, and 40°C. The data could be modeled using Peleg equation where it was found that the constant k1 was inversely related to temperature but the effect of temperature on k2 was negligible. In the second phase of the work a lab scale continuous screw conveyor as dehuller and two equipments, (1) fluidized bed dryer and (2) hull separator to function as agitato...
