Ali Caglar Gulluce, Tuncer Yilmaz, Erdogan Kaygin
American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.63032
Abstract: University preference is an important subject in that it is effective in the future lives of the students and for the universities to know the factors that are affecting the preferences of the students. Based on this importance, the factors that the students considered while making decision were investigated within the study. For this purpose, survey was applied to the students studying in the Faculty of Economics and Administrative Sciences of Kafkas University in 2013-2014 education term. 309 of the surveys obtained from the departments of administration, economics, and public administration were evaluated. According to the result of the factor analysis carried out, six dimensions consisting of prestige, opportunity, campus, knowledge, location, and economy were obtained. Besides, it was established that these factors differ in demographic properties.
Innervation of the Shoulder Joints in Turkish Shepherd Dogs (Karabash-Kangal), Curly Sheep and Native Hair Goats: An Anatomic Study
Bestami Yilmaz,Ali Bahadir
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2011.1934.1937
Abstract: This study is carried out with five Turkish shepherd dog (Canis familiaris), five curly sheep (Ovis aries) and five native hair goats (Capra hircus) which were adult and in different gender, macroanatomical, subgross and comprehensive research of sensible nerves (n.) innervating shoulder joint capsule was aimed. The shoulder joint capsule was found to be innervated by axillary and suprascapular nerves in Turkish shepherd dog, curly sheep and native hair goats in macroscopic and subgross analysis. The articular branch of axillary nerve was detected to generally terminate in joint capsule with 3 branches from caudolateral and suprascapular nerve was detected to terminate in joint capsule with 1 branch from lateral. In conclusion, number of the articular branches was found to be more in Turkish shepherd dogs and native hair goats compared to curly sheep. These differences were considered to be related to stated two species being more athletic and faster than curly sheep.

Ali YILMAZ,Recep MESUT
Trakya Universitesi Tip Fakultesi Dergisi , 2005,
Abstract: Objectives: The purpose of this study was to determine the range of motion (ROM) of the temporomandibular joint in normal population by means of a digital inclinometer and to establish a method of measurement for this joint. Study design: The study included 30 healthy male volunteers (mean age 20.5 years) who were studying at the School of Medicine of Trakya University. Maximum opening, right-left excursion and protraction degrees of the temporomandibular joint were measured with the use of an electronic digital inclinometer which was extremely sensitive and practicable on patients. The measurements were performed three times successively by the same person and at the same time of the day. Age and sex differences were ignored due to the preliminary nature of the study. Results: The mean values for maximum mouth opening, right excursion, left excursion, and protraction were found as 31.5°, 5.0°, 5.2°, and 13.9°, respectively. Conclusion: In our literature search, we could not find a similar study that measured angular values with an electronic digital inclinometer. These values can be used as objective criteria in the diagnosis and treatment of temporomandibular joint diseases in related specialties of medicine.

Empirical Comparison of Envelope-Tracking and Time-Domain Adaptive Integral Methods for Surface Integral Equations
Guneet Kaur,Ali E. Yilmaz
Physics , 2014,
Abstract: This paper presents a detailed evaluation of the envelope-tracking adaptive integral method (ET-AIM), an FFT-accelerated algorithm for analyzing electromagnetic scattering. ET-AIM is used to solve progressively more complex benchmark scattering problems and key parameters of the method (the auxiliary grid size, near-zone size, temporal basis function type, time-step size, and iterative solver tolerance) are optimized. The computational costs and accuracy of ET-AIM are compared to its time-domain counterpart, the time-domain adaptive integral method (TD-AIM), in the high-frequency regime, where the spatial discretization of the scattering object is determined by the minimum wavelength of interest rather than its geometrical features. Numerical results show that although ET-AIM and TD-AIM computation times are comparable when the bandwidth of interest is wide, the ET-AIM marching costs are dominated by iterative solution rather than scattered-field computations ('right-hand-side' computations) and that as the bandwidth of interest becomes narrower than 50% of the center frequency, ET-AIM computational costs become significantly smaller than TD-AIM ones. ET-AIM is also shown to efficiently solve large and complex scattering problems whose solution by TD-AIM is impractical.
A Low-Complexity Graph-Based LMMSE Receiver for MIMO ISI Channels with M-QAM Modulation
Pinar Sen,Ali Ozgur Yilmaz
Mathematics , 2014,
Abstract: In this paper, we propose a low complexity graph-based linear minimum mean square error (LMMSE) equalizer in order to remove inter-symbol and inter-stream interference in multiple input multiple output (MIMO) communication. The proposed state space representation inflicted on the graph provides linearly increasing computational complexity with block length. Also, owing to the Gaussian assumption used in the presented cycle-free factor graph, the complexity of the suggested equalizer structure is not affected by the size of the signalling space. In addition, we introduce an efficient way of computing extrinsic bit log-likelihood ratio (LLR) values for LMMSE estimation compatible with higher order alphabets which is shown to perform better than the other methods in the literature. Overall, we provide an efficient receiver structure reaching high data rates in frequency selective MIMO systems whose performance is shown to be very close to a genie-aided matched filter bound through extensive simulations.
Factor Graph Based LMMSE Filtering for Colored Gaussian Processes
Pinar Sen,Ali Ozgur Yilmaz
Computer Science , 2014,
Abstract: We propose a low complexity, graph based linear minimum mean square error (LMMSE) filter in which the non-white characteristics of a random process are taken into account. Our method corresponds to block LMMSE filtering, and has the advantage of complexity linearly increasing with the block length and the ease of incorporating the a priori information of the input signals whenever possible. The proposed method can be used with any random process with a known autocorrelation function with the help of an approximation to an autoregressive (AR) process. We show through extensive simulations that our method performs very close to the optimal block LMMSE filtering for Gaussian input signals.

International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.37A129
Abstract:

Poisoning is the disruption of functions of a living organism by any agent. The aim of this study is to identify the clinical and demographic characteristics of intoxication cases admitted to the Numune Training and Research Hospital emergency department. Characteristics such as age and gender of the patients, intoxication agents, and the results (discharge, forwarding, hospitalization, death etc.) were recorded to the prepared form. Data were assessed with the SPSS 15.0 software package and expressed. Quantitative variables were summarised as mean ± standard deviation. Frequency and percent distribution were used for the evaluation of data. The chi-squared test was used for comparison of the quailtative variables. p < 0.05 was accepted significant. The mean age of the receiving 651 poisoned patients was 32.04 ± 12.24 years. Of them, 67.7% were female. The most causes of poisoning agents were a pharmaceuticals (79.4%), carbonmonoxide (8.9%) and alcohols (7.1%). Gastric lavage was performed in 76% patients. Activated charcoal was administered in 81% patients. Antidotes treatment was applied in 7.4% patients. Most patients were evaluated and then treated and discharged from the ED (91.9%).
