Characterization of Riesz spaces with topologically full center

Let $E$ be a Riesz space and let $E^{\sim}$ denote its order dual. The orthomorphisms $Orth(E)$ on $E,$ and the ideal center $Z(E)$ of $E,$ are naturally embedded in $Orth(E^{\sim})$ and $Z(E^{\sim})$ respectively. We construct two unital algebra and order continuous Riesz homomorphisms $$\gamma:((Orth(E))^{\sim})_{n}^{\sim}\rightarrow Orth(E^{\sim})\text{ }$$ and $$m:Z(E)^{\prime\prime}\rightarrow Z(E^{\sim})$$ that extend the above mentioned natural inclusions respectively. Then, the range of $\gamma$ is an order ideal in $Orth(E^{\sim})$ if and only if $m$ is surjective. Furthermore, $m$ is surjective if and only if $E$ has a topologically full center. (That is, the $\sigma(E,E^{\sim})$-closure of $Z(E)x$ contains the order ideal generated by $x$ for each $x\in E_{+}.$) As a consequence, $E$ has a topologically full center $Z(E)$ if and only if $Z(E^{\sim})=\pi\cdot Z(E)^{\prime\prime}$ for some idempotent $\pi\in Z(E)^{\prime\prime}.

Error Rate Analysis of GF(q) Network Coded Detect-and-Forward Wireless Relay Networks Using Equivalent Relay Channel Models

This paper investigates simple means of analyzing the error rate performance of a general q-ary Galois Field network coded detect-and-forward cooperative relay network with known relay error statistics at the destination. Equivalent relay channels are used in obtaining an approximate error rate of the relay network, from which the diversity order is found. Error rate analyses using equivalent relay channel models are shown to be closely matched with simulation results. Using the equivalent relay channels, low complexity receivers are developed whose performances are close to that of the optimal maximum likelihood receiver.Comment: 28 pages, 10 figures.

Lefty’i Beklerken: Agitprop’un Öncü Bir Oyunu

DergiPark: 583335trakyasobedClifford Odets tarafından 1930’lu yılların BüyükBuhran döneminde yazılan Lefty’i Beklerken yalnızca Agitprop Tiyatrosu’nunsembol oyunlarından biri olmakla kalmaz ayrıca seyirci açısından duygusal vepolitik katarsis etki sağlamayı da başarır. Clifford Odets’in tek perdelikoyunu, eserdeki taksi şoförlerinin ekonomik yönden içler acısı durumunu vebazıları geriyedönüşlerle anlatılan ve onları greve gitmeye götüren bir diziolayı anlatır. Burjuva tiyatrosu fikrini, uygulamasını ve estetiğini yadsıyanve Agitprop özellikleriyle argümanlarını öncelikle ekonomik ve sosyal değişimibaşlatmak için destekleyen Lefty’i Beklerken, ezilen insanların kötü yaşamkoşullarını tasvir ederek ve yozlaşmış sendika ilişkilerini açığa vurarakinsanları harekete geçirmek için çağrıda bulunur. Çalışma, tarihsel ve kültürelkoşulları ve eseri oluşturan dünya görüşünü serimleyip Lefty’i Beklerken oyunuiçin teorik bir özet oluşturarak Amerikan Tiyatrosu’nun önemli eserlerindenbirinde Agitprop özelliklerini göstermeyi amaçlarWaiting for Lefty, which was written by CliffordOdets during the Great Depression of the thirties, has become not only anemblematic play of Agitprop Theatre but also it proves to be an emotional andpolitical catharsis on the part of the audience. Clifford Odets’ one-act playnarrates the story of cabdrivers’ heart-rending economic situation and the seriesof actions, some of which are narrated in the form of flashbacks, which leadthem to go on strike. Rejecting the conception, application and aesthetics ofbourgeois theatre and backing its arguments for the instigation of primarilyeconomic and social change by the aid of Agitprop features, Waiting for Leftycalls for mobilizing people by collective endeavor through the depiction of thedismal life conditions of the down-trodden people and corrupt union affairs. Bypresenting historical and cultural circumstances and perspective of weltanschauung which shape the play and drawinga theoretical synopsis for Waiting for Lefty, the study aims to display theagitprop features in one of the landmark play of American theatr

Characterization and corrosion performance of γ-glycidoxyropyltrimethoxsilane modified epoxy polymer

Thesis (Master)--İzmir Institute of Technology, Chemistry, İzmir, 2010Includes bibliographical references (leaves: 51-53)Text in English; Abstract: Turkish and Englishxii, 61 leavesEpoxy polymers have been widely used in a protective coating and adhesive due to its strong adhesion, high chemical resistance, and good processing characterisitics. However; epoxy coatings absorbs moisture easily, and the diffusion of absorbed water into the epoxy.steel interface weakens the interfacial adhesion strength between epoxy and steel in corrosive enviroment, due to the presence of hydrophilic hydroxy group in the cured network (epoxy/amine reaction). In this study, commercial epoxy polymer was chemically modified by γ-glycidoxypropyltrimethoxysilane monomer under the catalysis organotin compound via the reaction between hydroxyl group in epoxy polymer and alkoxy group in silanes, aiming to enhance the corrosion performans of epoxy polymer. Commercial epoxy polymer and silane modifed epoxy polymer were characterized by NMR spectroscopy, FTIR spectroscopy, epoxy equivalent weight measurement, contact angle measurement, surface energy measurement, hardness test and MEK double-rub test. The results showed that γ-glycidoxypropyltrimethoxysilane has been successfully grafted to epoxy polymer. Corrosion performance was evaluated by salt spray test acording to ASTM B117. The results showed that the chemically modified epoxy coating perform an improvement in resistance againts the penetration of water in polymeric resin and beter protectiveness on metalic corrosion

Is control in the hands of leaders?: The Answer comes from the entrepreneurial school

Strateji oluşturmada liderin rolü ve konumu konusunda işletme disiplininde çok çeşitli görüşler hakim olmuştur. Örgütün iç çevresinde en güçlü kim? Lider mi strateji oluşturur, yoksa örgüt dinamikleri mi? Örgüt mü stratejiyi izler, yoksa strateji mi örgütü? Örgüte kontrol mü hakimdir yoksa kaos mu? Tüm bu sorular henüz yanıt bulamamış ve kontrol-kaos paradoksu olarak literatürdeki yerini almıştır. Bu çalışmanın amacı, Mintzberg’in “Strategy Safari” adlı eserinde belirtmiş olduğu kontrol ve kaos üzerine oluşmuş olan paradoksu, on stratejik düşünce okulundan biri olan “Girişimcilik Okulu” çerçevesinde ele alıp “girişimci kişilik” ile strateji oluşturmada liderin elinde bulundurabileceği inisiyatifi vurgulamaktır.In Business Administration discipline there have been various views on leader’s statue and role in strategy formation. Who is the strongest in the internal environment of the organization? Does the leader form the strategies or organizational dynamics do so? Does the organization follow the strategy, or vice versa? Is there control over chaos or chaos over control in the organization? The aim of this study is to examine the control-chaos paradox stated in Mintzberg’s “Strategy Safari” book within the perspective of Entrepreneurial School, which is one of the ten schools of strategic management and to underline the initiative of the leader with his “entrepreneur-oriented character”

To be a Child in The Early Twentieth Century Ottoman Orphanages: Ten Children,Ten Portraits

Balkan Savaşları ve akabindeki I. Dünya Savaşı yıllarında Osmanlı coğrafyasında yetim çocuk sayısı ciddi biçimde artmıştır. Sahipsiz kalan çocuklar için 1914 yılından itibaren dârüleytamlar açılmıştır. Bu makalede öncelikle dârüleytamların nasıl açıldığı, amaçları ve kuruluş hikâyesi daha sonra ise doğrudan bu müesseselerde kalan çocukların kurumdaki hayat hikâyelerine yer verilmektedir. Mevcut literatürden farklı olarak kurumsal bir tarihe odaklanılmamakta, dârüleytam çocuklarının kurumdaki hikâyelerine yer verilerek bu çocuklar görünür kılınmaya çalışılmaktadır
