Safe Distributed Control of Wireless Power Transfer Networks
No full textWireless power transfer networks (WPTNs) are composed of dedicated energy transmitters (ETs) that charge energy receivers (ERs) via radio frequency waves. A safe-charging WPTN should keep electromagnetic radiation below predetermined limits meanwhile maximizing the transmitted power. In this paper, we consider this requirement as an optimization problem: the maximization of harvested power by ERs subject to the electro-magnetic safety constraints. In order to provide an approximated solution to this problem, we introduce a dual ascent-like distributed charging algorithm that enables ETs to work without global information and satisfy safety constraints asymptotically. We provide an in-depth theoretical analysis of our algorithm which is supported by numerical simulations.Accepted author manuscriptEmbedded System

Digital Influencers in New Media as a Marketing Communicatıon Tool: A Research About The Effects of Vloggers' Characteristics and Types of Knowledge on Vlogger’ Reputation
Get PDFGünden güne gücü artan yeni medyanın önemli oyuncuları olarak vloggerlar markaların iletişim çabalarına destek olurken, kendilerine bağlı kitlelerin satın alma kararlarını oluşturmalarında etkin rol oynamaktadırlar. Vloggerların karakteristik özelliklerinin yanında sundukları bilgi birikimin kaynağı ve bunu nasıl bir ruh halinde sundukları, vlogger tercihini ve sonrasında kendilerine duyulan itibar algısını etkilemektedir. Bu çalışmada iletişim çabalarında vlogları kullanacak markaların özellikle seçilen vloggerın bilgi birikimi tipleri ve karakteristik özelliklerinin vloggerın itibar oluşumunda ne kadar etkili olduğu anlaşılmaya çalışılmıştır. Bu sebeple, kolayda örneklem yöntemi kullanılarak 224 katılımcıyla yapılan anket veri toplama yöntemiyle söz konusu ilişki irdelenmiştir. Sonuç olarak literatürde henüz az sayıda olan vlog üzerine yapılacak olan gelecekteki çalışmalara ışık tutması amacıyla vloggerların iletişim aracı olarak seçimi/kullanımında, içerik yaratılmasında marka ile özdeşleşen iletişim stratejilerinin sunulmasının önemi vurgulanmaktadır.The growing power of vloggers, new players of new media, and their effective influence on their connected network’s buying decisions have emerged as a new communication tool for brands. Vloggers’ characteristics and knowledge have important relationship with vloggers’ reputation. The purpose of this paper is to investigate how consumers respond to this type of brand communication activity (vlogging), and evaluate its effects on the choosen vloggers’ reputation. A survey with convenience sampling involving 224 vlog audiences as participants was analyzed in the empirical study to investigate the relationship between the previously mentioned variables. As a result, with the aim of being light for future studies about vlogs; in case of using vloggers as a marketing communication tool, it must be well understood that creating/choosing synergetic content with the elements of brand communication mix is important. _x000D_

Recently many studies have shown that vloggers' main characteristics andblog types have a direct influence on users as an effective medium. As vlogs have become animportant tool for interactive communication, the purpose of this paper is to understand therelationship between vloggers'characteristics, trust, word of mouth and intention of onlineshopping. This study implies that the vblog can be a meaningful learning platform and thevlogging can be a significant medium in having/sharing the informal knowledge for onlineshopping.Design/Methodology/Approach-Based on various theories, the structural equation modelling approach was proposed in this study. A survey with convenience sampling involving 357 vlogusers as participants was analyzed in the empirical study to investigatewhether theusefulness of vbloggers' recommendations and trusting beliefs towards vblogger hasinfluence on consumers' behavioral intentions towards word of mouth and online shopping.Findings-The results showed that vloggers' characteristics had significant influential effecton vlog users' attitude towards and intention to shop online. Moreover, the findings indicatedthat engagement characteristics of vloggers elicited trust more than authoritative knowledgedcharacteristics of vloggers. As a result ofthe path analysis it is discovered that the intentionto shop online is triggered through trust and word of mouth communication. Engagementknowledge has more power on the relationship between word of mouth communication andthe intention to purchase. As much as users trust that the content of the vlog is based on trueinformation and not for advertising strategy, the more likely they want to share theinformation virally. That would have a direct impact to the increasing intention to buy.Originality/Value-The originality of this paper is to study vlogging, which is a new workingfield in the scholarly literature, and its correlation to users' intention to buy. This studyespecially analyzes the vlog characteristics and their increasingly leading factors tousers/readers' attractiveness intention to buy.

No full textThe aim of this study was investigate prospective teachers' attitudes towards teaching profession at the Education Faculty at Trakya University with respect to the gender and disciplines. In the present study, the data was collected from 120 prospective teachers from Science and Technology Education and Computer and Instructional Technology Education departments as well as from pedagogical formation certificate program students graduated from Faculty of Arts and Sciences. The data was collected by the Attitude Measurement Scale for Teaching Profession developed by Ustuner (2006). The findings revealed that female prospective teachers had more positive attitude towards teaching, and science education and formation students' attitudes were more positive than that of computer education students
ANXIETY OF STUDENTS PREPARING FOR THE UNIVERSITY ENTRANCE EXAM TOWARDS MATH LESSONS
No full textIt is known that one of the crucial factors affecting the students' success at math lessons negatively is math anxiety. In most general meaning, math anxiety may be defined as an anxiety and fear emerging in relation to certain math situations. The aim of this study is to find out the reasons of math anxiety observed among students attending privet courses. To collect the needed data of the study an anxiety scale was administered to 450 students attending different private courses in the city of Kirklareli, Turkey. The obtained data was processed by data processing software. After the required data interpretation steps were concluded, students' math anxiety reasons were determined and in relation some solutions were suggested

Allium sultanae-ismailii (Amaryllidaceae), a new species from eastern Turkey
No full textAllium sultanae-ismailii Yildirim (Amaryllidaceae) is described here as a new species. Diagnostic morphological characters, a full description, and detailed illustrations are given herein. A. sultanae-ismailii is restricted to Mt. Akbabacali in Darende district of Malatya province in eastern Anatolia, Turkey. According to its morphological features, it belongs to Allium subgen. Melanocrommyum sect. Melanocrommyum. It shows morphological similarities with A. purpureoviride, which belong to the same subgenus and section. However, it is easily distinguished from this latter species by the dark purple tepals, shorter stem, initially stellate perianth segments, longer style, undivided and very short tripartite stigma, and distribution at higher altitudes.TUBITAK (The Scientific and Technological research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [113 Z 072]; Ege University (EBILTEM)Ege University [2014 BIL 004]The author is grateful to Prof. Reinhard M.
