Article Red Vienna: Ideology, Architecture and Art in the Reumannhof Municipal Social Housing(Middle East Technical Univ, 2024) Pfeiffer Tas, Sule; Temel, Rabia; Taş, Şule PFEIFFERThis study focuses on the Reumannh of Social Housing Complex, which was designed by Hubert Gessner (1871-1943) and constructed between 1924 and 1926 in Vienna. It was one of the largest buildings as part of the Municipal Social Housing Program for workers implemented under the leadership of Jakob Reumann, who was the mayor of Vienna between 1919 and 1923. According to the social democratic ideology in Vienna, known as the Red Vienna period (1919-1934) of the city administration, this program aimed to meet the housing needs of the working class and to provide them with better living conditions. Due to the increase in worker migration to the city after the Industrial Revolution and upon the demolition of the city during World War I, a housing crisis emerged in Vienna and unfavorable living conditions - such as one-room apartments and rental beds even for a few hours - became a necessity. The paper attempts to probe into the nature of the connection between the Reumannh of Complex architecture and the Red Vienna ideology in light of the social democratic perspective of the working class. In order to do so, the entire structure - known as "the palace of the working class" - is analyzed in detail while pointing to similar social housing complexes, such as Metzleinstalerh of on the Margareteng & uuml;rtel known as "Proletarian's Boulevard" and nearby. Additionally, the standardization criteria, as envisioned within the context of the social housing program, are examined to find out any traces of their presence (or improvements/modifications upon them) in the Reumannh of Complex. In the context of the political and socio-economic conditions of that era, a comparative analysis of the architectural elements and landscape architecture is conducted, such as courtyards and Haydn park on the front in the latter case. Original archival documents, photographs, and drawings of the complex were collected and during the course of the field research, photographs were taken. A housing typology and drawings were made in accordance with the general floor plan of the building, drawn by Gessner himself to determine the details related to the features of the houses - such as kitchen, living room+kitchen, and the number and function of the rooms - in order to determine the reflection of the living comfort promised by the social democratic ideology. As a result, three main plan types were identified based on the spaces contained within the houses, and subgroups were created according to balconies, terraces, or bay windows, all of which provided daylight and fresh air. In conclusion, the research establishes that the Reumannhof Complex houses, common facilities as terraces, infant school, laundry rooms, etc. all implemented standards that were mostly aligned with those related to welfare and in line with the principles of social democratic ideology. Lastly, it is revealed that architectural and artistic elements, such as wrought iron, ceramic panels illustrating craftsmen and different professions, motifs, and sculptures, not only reflect the social democratic ideology and motto, but also create new living environments by integrating architectural design with green spaces for the working class. As witness to this assertion, it is useful to notice that the complex still serves the function of economic housing for the working class and remains important as a symbol of social democratic ideology.Article Citation - Scopus: 1Anxiety and Depression After Cesarean: Non-Pharmacological Evidence Based Practices;(Dokuz Eylul University, 2022) Terzioğlu,F.; Gençbaş,D.; Boztepe,H.; Doğu,N.; Akdeniz,C.; Yüceer,B.The purpose of this review is to examine the non-pharmacological evidence-based practices of anxiety and depression after a cesarean section delivery. Postpartum anxiety and depression have increased in the last decade, the rates of postpartum depression are around 13% worldwide. In the postpartum period, women may experience anxiety and depression due to the operation they have undergone; such as being in an unfamiliar environment, facing new technological equipment and encounters with the medical teams, the post-operative pain, the new roles women undertake as mothers. One of the factors that increase anxiety and depression in the postpartum period is the type of delivery. In Turkey, the rate of cesarean delivery is comparatively high, which is approximately 52%. Anxiety and depression after cesarean section develop due to fear and concern such as the complications that may occur during and after the mother's anesthesia, the possibility delaying breastfeeding her baby, and experiencing pain. Non-pharmacological evidence-based applications such as reiki, acupressure, hand and foot massage, yoga, reflexology, aromatherapy, skin to skin care, nursing care protocols were found to be effective in studies conducted to reduce anxiety and depression after cesarean-section. Nurses who have critical roles and responsibilities in pre-and post-cesarean care practices are recommended to include these evidence-based non-pharmacological practices in routine care practices. © 2022, Dokuz Eylul University.

HTPEM type fuel cells gain the highest interest lately, due to their advantages in terms of increasing efficiency and power quality, reducing harmful emissions and flexibility of operation with respect to the other fuels. The micro-cogeneration system involves producing both electrical energy and hot water and/or vapor together in an economical way, utilizing single fuel (HTPEM fuel cells) for household applications. During the operation of the fuel cell, for high efficiency and stable power production, the access heat of the stack should be removed constantly and the temperature of the stack should be held stable. Heat recovered from the designed innovative cooling system is used for acquiring energy for heating water. This way, thermal efficiency is almost doubled compared to simple cycle. In the scope of this study, 225 W HTPEM fuel cell stack is designed and tested at 160 degrees C operation temperature with hydrogen gas and air. During operation, for homogenous distribution of temperature among the cells, for a short start up period leading to a fast required steady state temperature and for constantly removing the access heat produced in the cell, the cell stack is cooled by using a cooling fluid (Heat Transfer Oil 32- Petrol Ofisi). Selection of insulation material type and thickness for the cell stack is done using natural convection and radiation loss calculations. For the most efficient operating conditions, micro-cogeneration system water inlet and exit temperatures, water and cooling fluid flow rates, convenient pipe diameter and pump power calculations are done to finalize the design. With the cogeneration system designed during the studies, by recovering the access heat of the insulated HTPEM cell stack, district water with initial temperature of 15-20 degrees C is heated around 50 degrees C. Data gathered during studies indicate that fuel cell micro-cogeneration application is highly viable.Conference Object Bar code localization by image processing;(2005) Öktem,R.; Çetin,A.E.This paper addresses the problem of bar code recognition by use of image processing. Bar codes are composed of parallel alternating dark-light stripes; hence they also appear as parallel lines connected at some orientation in a binary edge map. The proposed algorithms exploit that feature and use morphology and free angle thresholding for localization. Edge map is formed by Sobel operator and binary subband decomposition separately, and the two methods are compared in terms of time complexity and performance. Detailed discussion of test results are also presented. ©2005 IEEE.Conference Object Producing Synthetic Speech From Turkish Text Via a Single Sound Synthesizer Ic;(2010) Tora,H.; Cengizler,Ç.In this study, new speech sounds were created for Turkish letters from the allophones listed in SpeakJet Magnevation complex sound synthesizer IC, which is intended for English, by selecting and paring the most similiar phonems. Consequently, Turkish Text to Speech synthesizer was implemented with minimum enviroment elements and no physical modification on IC. Paring based on SAMPA showed that all Turkish phonems can be obtained from English allophones with high compatibility. The text to speech and paring algorithm presented herein is developed to be embedded in a microcontroller and capable to vocalize a random Turkish text with SpeakJet IC.Conference Object Design and Fabrication of Dual-Frequency H-Shaped Antenna;(IEEE, 2013) Dagdeviren,B.; Yavuz Kapusuz,K.; Can,S.; Aydin,E.; Kapusuz, K.

It is the task of the ESM system to de-interleave this mixed pulse sequence and thus to identify the surrounding threatening emitters. In this processing, pulse repetition interval (PRI) modulation recognition has a significant role due to the fact that it can reveal the hidden patterns inside pulse repetition intervals and thus help identify the emission source and its functional purpose. In this paper, we propose new wavelet-based features for the recognition of jittered and stagger PRI modulation types. The recognition of these types are heavily based on histogram features. Experimental results show that the proposed feature set have very high recognition rates and outperform histogram based methods. © 2015 IEEE.Article Citation - Scopus: 1Yielding of Functionally Graded Long Tubes Under Thermal Loading;(2006) Akiş,T.The elastic behavior of a functionally graded non-uniform heat generating long tube is investigated analytically. The thermal conductivity and the modulus of elasticity of the tube material are assumed to vary radially in nonlinear forms. Making use of Tresca's yield criterion, the effect of grading parameters on the yielding behavior of the tube is investigated. It is observed that plastic flow may commence at the inner surface, at the outer surface or inside the tube depending on the functionally grading parameters.Article Citation - WoS: 9Citation - Scopus: 9Elektrik Direnç Punta Kaynağı ile Birleştirilen %15 Deforme Edilmiş Twıp Çeliğinde Kaynak Akımının Mikroyapı ve Mekanik Özellikler Üzerindeki Etkisi(Gazi Univ, Fac Engineering Architecture, 2020) Aydın, Hakan; Tutar, Mümin; Davut, Kemal; Bayram, AliÇalışmada, %15 deforme edilmiş TWIP saclarının elektrik direnç punta kaynağıyla birleştirmelerindekaynak akımının mikroyapı ve mekanik özellikler üzerindeki etkisi incelenmiştir. Mikroyapıkarakterizasyonunda optik mikroskop, taramalı elektron mikroskobu (SEM), SEM/Enerji dağılımlı X-ışınıSpektroskopisi (SEM-EDS) ve SEM/Elektron Geri Saçılım Kırınımı (SEM-EBSD) teknikleri kullanılmıştır.Mekanik özelliklerin belirlenmesinde, mikrosertlik ölçümleri ve çekme testleri yapılmıştır. Kaynak akımıartışı ile erime bölgesindeki kaynak boşlukları azalırken, çekirdek çapı, çökme miktarı ve ısı tesiri altındakibölge (ITAB) genişliği yaklaşık lineer bir şekilde artmıştır. Kaynak bölgesinde deformasyon ikizleri ortadankalkarken, ITAB’da iri tavlama ikizleri ortaya çıkmıştır. Ayrıca, kaynak akımı artışıyla ITAB’daki taneirileşmesi ve ikiz kalınlıkları artmıştır. Ancak, kaynak işlemi kaynak bölgesinde herhangi bir fazdönüşümüne neden olmamıştır. Bu sebeple, kaynak bölgesi sertlik değerleri temel malzemenin sertlikdeğerlerinden oldukça düşük kalmıştır. Genel itibariyle, en düşük sertlikler ITAB’da gözlenmiştir. Kaynakakımı ile kaynak bölgesi sertlik değerleri arasında herhangi bir korelasyon elde edilmemiştir. Kopma yükükaynak akımı ile artmıştır: En yüksek kopma yükü 10 kA kaynak akımında elde edilmiştir. Düşük kaynakakımlarında aryüzey tipi kırılma meydana gelirken yüksek kaynak akımlarında buton çekirdek tipi kırılmalarortaya çıkmıştır. Kırılma karakteristikleri genel itibariyle gevrek-sünek karışımıdır. Daha yüksekmukavemete sahip numunelerde gevrek-sünek kırılma bölgesinde sünek kırılma, gevrek kırılma bölgesindeise trans-granular kırılma karakteristikleri artış göstermiştir.Conference Object Simulation Based Surgical Education Programs and Hand Performance;(Institute of Electrical and Electronics Engineers Inc., 2017) Eyuboglu,B.G.; Topalli,D.; Cagiltay,N.E.; Tonbul,G.The performance of the left- and right-hands of a person may be different from each other. In general, people use one hand with a superior performance compared to the other hand where that hand is preferred for performing daily activities. It is critical to understand their preference for right or left hand use, especially in cases where the skills should be improved to use both hands precisely in activities required special abilities such as endoscopic surgical operations. A better understanding of these cases will improve the quality of existing surgical education programs, and make a major contribution specifically in designing, improving and managing of simulation-based instructional technologies. In this study, the right- and left-hand preferences (handedness) of people are analyzed from the literature and a simulation-based experimental study is conducted in order to examine the performance differences of the participants while using their right and left hands. The results of this study aimed to guide the curriculum designers and instructional system developers for better designing and developing simulation-based surgical education programs. © 2016 IEEE.
