Design of a Multi-Agent System for Process Monitoring and Supervision
New process monitoring and control strategies are developing every day together with process automation strategies to satisfy the needs of diverse industries. New automation systems are being developed with more capabilities for safety and reliability issues. Fault detection and diagnosis, and process monitoring and supervision are some of the new and promising growth areas in process control. With the help of the development of powerful computer systems, the extensive amount of process data from all over the plant can be put to use in an efficient manner by storing and manipulation. With this development, data-driven process monitoring approaches had the chance to emerge compared to model-based process monitoring approaches, where the quantitative model is known as a priori knowledge. Therefore, the objective of this research is to layout the basis for designing and implementing a multi-agent system for process monitoring and supervision. The agent-based programming approach adopted in our research provides a number of advantages, such as, flexibility, adaptation and ease of use. In its current status, the designed multi-agent system architecture has the three different functionalities ready for use for process monitoring and supervision. It allows: a) easy manipulation and preprocessing of plant data both for training and online application; b) detection of process faults; and c) diagnosis of the source of the fault. In addition, a number of alternative data driven techniques were implemented to perform monitoring and supervision tasks: Principal Component Analysis (PCA), Fisher Discriminant Analysis (FDA), and Self-Organizing Maps (SOM). The process system designed in this research project is generic in the sense that it can be used for multiple applications. The process monitoring system is successfully tested with Tennessee Eastman Process application. Fault detection rates and fault diagnosis rates are compared amongst PCA, FDA, and SOM for different faults using the proposed framework
Static analysis of masonry arched and buttressed retaining walls
There is a common typology of retaining walls, in places with hard soils without water table, which consist in arches in the upper part and buttressed pillars transmitting the forces from the arches and the earth pressure to the foundation. There is very interesting to assess the capacity of this type of retaining walls through engineering tools
NGOs in Turkey’s Media Field: Causes, Sources and Potentials for Development
This study elaborates on the non-governmental organizations in Turkey that operate within the broadly defined media field, where a wide variety of organizations, associations, movements and platforms are observed. Focusing on the two most disputed subdomains of the media in Turkey, namely news and information technologies, this descriptive research, at the first level, examines the causes or existence reasons of the NGOs along with their strategies, operations and achievements or failures. Their organizational forms and resources are studied at the second level. Third level of the study investigates their relations with a particular focus on their operational context. It has been found that the socio-political environment in the country or ongoing crises of different sorts, multiply the number of issues, and the existing complications impede mobilization

Patients Admitted to Tertiary Health Care Center: Cancer Screening Program Awareness Study
Background: Screening programs for detecting cancer early are critically important for a better prognosis and a long acting survival. In our country, second most common cause of death is cancers with the rate of 21.1 %. The aim of this study was to investigate cancer screening and awareness in healthy individuals in our region.
Study Design: The survey was conducted on 400 randomly selected patients who were admitted to Pamukkale University hospital with the method of face to face interview in May 2016 Statistical evaluation was performed using SPSS v22

Does age of onset in essential tremor have a bimodal distribution? data from a tertiary referral setting and a population-based study
Background/Aims: The distribution of age of onset of essential tremor (ET) is unclear, with discrepancies in the literature. Some data suggest a bimodal distribution and other data 1 late-life peak. We studied age of ET onset in 2 distinct settings: a population-based study and a tertiary referral center. Methods: Age of onset data were collected. Results: In the population, there was only a small peak at the age of ≤30 years (14.1% of cases) but a clear peak in later life (85.9% of cases). In the tertiary referral center, a bimodal distribution was apparent with 1 large peak (42.2% of cases) at the age of ≤40 years and the second large peak (57.8% of cases) in later life. Familial cases accounted for only 52.6% of young-onset cases from the population, yet 82.7% from the tertiary center. Discussion: In the population-based study, a peak in later life was clearly present but a young-onset peak was barely discernable, comprising few cases. By contrast, in a tertiary referral center, age of onset was clearly bimodal. While age of ET onset is often said to be bimodal, this may be due to the preferential referral to tertiary centers of patients with young-onset, familial ET

Isolated head tremor : part of the clinical spectrum of essential tremor? data from population-based and clinic-based case samples
Essential tremor (ET) still remains a clinical diagnosis. Nonetheless, it is misdiagnosed in 30 to 50% of cases. There are a number of areas of diagnostic uncertainty. One of these is isolated head tremor, on which published data are limited and at variance. We studied the prevalence of isolated head (i.e., neck) tremor in ET in two population-based studies (Turkey and New York) and a large clinical sample (New York); these 583 ET cases all received the same detailed tremor examination. Head tremor with mild arm tremor occurred in a very small percentage of cases in each sample (1.9 - 3.1%, overall 2.7%). Nearly all of them were women. Head tremor in the complete absence of arm tremor was not observed in any cases (0.0%). These clinical data may be of value to clinicians in practice settings and researchers in phenotyping efforts in the emerging field of ET genetics
The comparison of effects of Roux-n-y gastric bypass and sleeve gastrectomy on excess weight loss in morbidly obese patients
Background: Obesity an important health problem which has become a worldwide epidemic that effects both developed countries and developing countries. Bariatric surgery is the most efficient cure for morbid obesity. Authors retrospectively reviewed the results of different techniques in bariatric surgery to assess the efficiency of initial operations.Methods: The medical files and operation notes and the one-year follow-up of patients were reviewed. The outcomes of sleeve gastrectomy (SG) and gastric roux-n-y bypass (RYGBP) operations were reviewed and their effects on excess weight loss were investigated.Results: Overall, there were 97 patients included in the study, the majority of which were female (87/97, or 90%). The mean age of the SG group was 42.01±8.48 years versus 36±8.32 years in the RYGBP group, with p=0.007. Excess weight loss percentages were 51.7% and 57% for sleeve gastrectomy and RYGBP, respectively, p=0.491. Both operations are effective in reducing comorbidities.Conclusions: In the RYGBP procedure there is more excess weight loss than the results of SG procedure but the difference is not statistically significant. In both procedures, the initial results on weight loss and reduction of comorbidities are comparable. Because SG is less traumatic and relatively easier to perform, it can be the preferred operation for morbid obesity
