Methyl methacrylate in external fixation of supracondylar humerus fractures: An experimental study

GÜLEÇ, Ali | ACAR, Mehmet Ali | AYDIN, Bahattin Kerem | DEMİR, Teyfik | ÖZKAYA, Mustafa

Supracondylar humerus fractures are common fractures around the elbow. Open fractures, comminuted metaphyseal fractures and also fractures with bone loss may need to be treated with external fixators. The aim of this study is to compare two different external fixators, tubular external fixators and polymethyl methacrylate with K wires external fixators, with regard to stiffness and stability for metaphyseal-diaphyseal osteotomies of distal humerus close to the joint. Six matched pairs (24 specimens) of second-generation sawbone humerus were prepared in a standard fashion to create a metaphysea ...Daha fazlası

The Association between Chronicity of Migraine and Complementary and Alternative Medication Use: The Turkish Perspective

ERTEM, Devrimsel Harika | BAŞARIR, İlker | ERYİĞİT BARAN, Gözde | KOCABIYIK, Nurhan | İLİK, Faik

Background and Purpose: The term of Complementary and Alternative Medication (CAM) is described by patients as all types of practices to prevent or treat illnesses, which are not currently considered as a part of conventional medicine. Although the advance in treatment for migraine, some patients prefer CAM therapies due to their concerns about conventional therapies. The aim of this study was to evaluate the association between CAM use and chronicity of migraine among Turkish migraineurs. Methods: Consecutive episodic and chronic migraine patients were recruited. A questionnaire of a list of ...Daha fazlası

Using Internet: A Mechanism to Develop Market Share

MOSTAVAFI SHIRAZI, Seyedeh Fatemeh

This chapter presents the subject area of the Internet as an international form of media and examines related issues. It begins by considering the Internet as a source of information in various forms of social network sites that enables any individual to post their experiences, opinions and evaluations of tourism destination. This provides a summary of the existing state of knowledge concerning to social network sites and word of mouth (WMO) recommendation. In addition, it serves to clarify the associated word of mouth and market share development. Introduction Using the Internet as an interna ...Daha fazlası

Comparison Between The Effects Of Different Types Of Membership Functions On Fuzzy Logic For Hydroxy Dry Cell Performance

IŞIKTAŞ, Abdullah | DİNÇER, Kevser | ATA, Sadık

In this study, hydroxy (HHO) dry cell performances in terms of voltage, current and temperature were modeled with Rule-Based Mamdani-Type Fuzzy (RBMTF) modeling technique. Input parameters plate combination and time, output parameters voltage, current, temperature were described by RBMTF if-the rules. Current, voltage and temperature were measured for the different membership functions. Numerical parameters of input and output variables were fuzzificated as linguistic variables: very very low (L-1), very low (L-2), low (L-3), negative medium (L-4), medium (L-5), positive medium (L-6), high (L- ...Daha fazlası

A 3D face animation system for mobile devices

MENDİ, Engin

In this paper, we present a 3D face animation system rendered on mobile devices. The system automatically creates realistic facial animation from text input with emotion tags. First, an input string is converted into synthetic voice and phonetic information. Then, 3D head model performs facial movements synchronized to the speech. The proposed system offers an affordable quick solution for applications that require virtual actors speaking text in which human-machine interfaces on mobile devices can profit.

Modeling of the Effects of Cyclic Voltammetry (CV) Using Fuzzy Logic with Different Membership Functions for Proton Exchange Membrane Fuel Cell (PEM) with Polyvinyl Alcohol/Nano Silver (PVA/Ag)

ERSOYOĞLU, Ali Serhat | ATA, Sadık | DİNÇER, Kevser | ÖNAL, Güral | YILMAZ, Yusuf

In this study, the effects of cyclic voltammetry (CV) has been modeled with Rule-based mamdani-type fuzzy (RBMTF), by using experimental data for proton exchange membrane fuel cell with PVA/AG. In the system developed, RBMTF apply input parameters are CV, scan rate and time, output parameters are current density and voltage. 12300 values for experimental study also obtained with RBMTF. Membership functions (MFs) are the building blocks of fuzzy set theory, i.e., fuzziness in a fuzzy set is determined by its MF. Accordingly, the shapes of MFs are important for a particular problem since they ef ...Daha fazlası

Statistical electromagnetics for antennas

AÇIKGÖZ, Hulusi | ARYA, Ravi Kumar | WIART, Joe | MITTRA, Raj

After a brief introduction, this chapter discusses the state of the art of variable antennas and previous works on these antennas are reviewed. This is followed by an introduction to the most common statistical analysis techniques used for the purpose of the uncertainty propagation. The application of the statistical method to some real case structures is then considered; split ring resonator (SRR) and wearable antennas.

Investigation of the Mantle System Applied to Outer Shell of Apartment Buildings in Terms of Energy Efficiency (Erzincan Case)

ÇAĞLAR, Arzu | ÇAĞLAR, Hakan | KOÇU, Nazım | YAZICIOĞLU, Salih

Energy is a phenomenon that leads to conflicts, internal conflicts, and antagonism in all areas of life. Considering that we are dependent on foreign countries in the field of energy, the conservation of energy is getting more and more important day by day. A large portion of the energy consumed in Turkey is used to heat houses. It is very important to maintain the heat and keep it on the field as well as to heat the house. It is seen that the best and economical way of keeping the heat is thermal insulation in the apartments. In this study, five apartments in Erzincan which is in the 4th grad ...Daha fazlası

Empirical Study of Email Security Threats and Countermeasures

DHINAHAR, Nagamalai | DHINAHAR, Beatrice Cynthia | ÖZCAN, Abdulkadir | OKATAN, Ali | LEE, Jae-Kwang

Due to wide range of users, email had emerged as one of the preferred method to intrude Local area networks and end users. In this paper we examine the characteristics of various email security threats and the technology used by attackers. In order to counter defense technology, attackers change their mode of operation frequently. The continuous evaluation of attacker's pattern will help the industry to combat attacks effectively. In our study, we collected several thousand spam from a corporate server for a period of 12 months from Jan 2012 to Jan 2013. From the collected data, we identified ...Daha fazlası
