HandMECH—Mechanical hand prosthesis: Conceptual design of the hand compartment
No full textIn this study, conceptual design of the hand compartment of a body-powered hand prosthesis, HandMECH, is presented. HandMECH is a body-powered prosthesis and the hand compartment is designed according to human finger size and range of motion (RoM). Moreover, the design is governed by the daily activities performed by hand. In this regard, three types of grasp that are mostly used are identified. The thumb is designed with three degrees of freedom (DoF), i.e., translation and rotation, the index finger with three rotational DoF, and the other three fingers that generally move together are designed as combined and having one rotational DoF. In order to give the human finger flexibility, the fingers are designed to be made of flexible material and the other parts are of ABS material with the consideration of 3D printer for prototyping. CAD model is presented as an outcome of this study
Reversing the design process in the introductory architectural design studio: The exploratory function of sketch modelling
No full textThis study investigated the exploratory potentials of sketch modelling in the introductory architectural design studio. It focused on the course ‘ARCH 102 Architectural Design Studio I’, in which sketch modelling was deployed as a creative problem-solving practice, triggering an exploratory process through thinking and doing. The study adopted the case-study method. Hence, the principal sources of data are student projects and studio tutors’ first-hand observations and reflections. The findings reveal that, along with its iterative and communicative functions, the exploratory nature of sketch modelling helps first-year students overcome design issues in the making of design. The findings lay the groundwork for more systematic studies on reflective learning practices in design education
3D simulation of droplet impact on static and moving walls
No full textIn the present study, the contact angle model and the origin of the parasitic current, precisely, the relation of the parasitic current with grid distribution, have been studied to accurately predict droplet impact on static and moving walls in the volume of fluid (VOF) framework. The authors have quantitatively shown that the number of neighboring cells of the central cell influences the gradient calculations regarding the generation and spatial distribution of parasitic current. Accordingly, the polyhedral cell structure provides smoother interface gradient distribution than the Cartesian grid structure. After implementing a modified Kistler contact angle model in OpenFOAM and using the polyhedral grid for the simulations, we could accurately validate transient droplet shapes formed upon impact with those obtained from experiments. Droplet outcomes obtained, such as deposition, partial rebound, and split deposition on stationary and moving smooth surfaces, are consistent with experimental results.TÜBİTA
Velayeti olmayan babaların boşanma ve velayet sonrası deneyimleri: ebeveyn yabancılaşmasıyla ilgili fenomenolojik bir çalışma
No full textParental alienation is one of the outcomes that divorced families may experience during and after the divorce process. In parental alienation, the child is consciously alienated from the targeted parent by the targeting one by using different strategies and manipulations. By using family systems theory as the fundamental framework, the current study explores the experiences of noncustodial fathers in the context of parental alienation after the divorce and custody processes from a multidisciplinary lens. Seven fathers, who scored higher on the Rowland Parental Alienation Scale than the average score of the sampling pool that is consisted of noncustodial fathers, were purposefully selected. Parental alienation experiences of fathers were clustered by using interpretative phenomenological analysis, and it yielded six group experiential themes: “Ways of parental alienation”, “Fathers’ psychological outcomes”, “Father-child relationship outcomes”, “Experiences with professional services”, “Gender-based inequality”, and “Ways to light up darkness”, and a total 24 subthemes. Current study findings are discussed in the context of the family systems theory, existing literature around divorce and parental alienation, strengths, limitations, future research directions, and clinical and legal implications.Ebeveyn yabancılaşması, boşanmış ailelerin boşanma sürecinde ve sonrasında yaşayabileceği sonuçlardan biridir. Ebeveyn yabancılaşmasında çocuk, hedef gösteren ebeveyn tarafından farklı stratejiler ve manipülasyonlar kullanılarak bilinçli olarak hedef gösterilen ebeveyne karşı yabancılaştırılır. Aile sistemleri teorisini temel çerçeve olarak kullanan bu çalışma, çocuğunun velayeti olmayan babaların boşanma ve velayet süreçlerinden sonra ebeveyn yabancılaşması bağlamında deneyimlerini multidisipliner bir lensle araştırmaktadır. Velayeti olmayan babalardan oluşan bir örneklem havuzunun Rowland Ebeveyn Yabancılaşma Ölçeği'ndeki ortalama puanından daha yüksek puan alan yedi baba amaçlı örnekleme yapılarak seçilmiştir. Yorumlayıcı olgubilim analizi kullanılarak babaların ebeveyn yabancılaşma deneyimleri “Ebeveyn yabancılaşmasının yolları”, “Babaların psikolojik çıktıları”, “Baba-çocuk ilişkisi çıktıları”, “Profesyonel servislerle deneyimler”, “Cinsiyet temelli eşitsizlik” ve “Karanlığı aydınlatmanın yolları” olmak üzere altı ana tema ve toplamda 24 alt tema altında kümelendirilmiştir. Çalışmanın bulguları; aile sistemleri teorisi, boşanma ve ebeveyn yabancılaşması etrafındaki mevcut literatür, güçlü yönler, kısıtlı kaldığı noktalar, gelecekteki araştırmalar için öneriler ve klinik ve yasal uygulamalar bağlamında tartışılmaktadır
Interrelation between grid systems and star polygons of muqarnas ground projection plans
No full textMany muqarnas ground projection plans contain stars with unequal edge lengths in their compositions. In this study, the geometric reasons behind the unequality of star edge lengths in muqarnas ground projection plans have been searched. The main gates with complex-looking muqarnas belonging to the period of Suleiman the Magnificent (Kanuni Sultan Suleyman), designed by Architect Sinan in Istanbul, have been selected to examine. From the data obtained by 3D laser scanning and from the verification made, it has been confirmed that there are stars with unequal edge lengths in these muqarnas plans. From the geometrical examinations made according to the shape grammar theory, it was concluded that the muqarnas plans were created using spider-web grid and square grid layouts. It was also concluded that these grid types cause some of the star edge lengths to be unequal.Publisher versio
Unauthorized use of others' business products in unfair competition law
No full textYeni Türk Ticaret Kanunu ile haksız rekabetin temelini teşkil eden emeğin korunması; yeni hüküm olan “başkalarının iş ürünlerinden yetkisiz yararlanılması” hali ile hüküm altına alınmıştır. Rekabetin sağlıklı bir ortamda hukuka uygun devamlılığının sağlanması için, rakiplerin emek ve deneyimleri ile ortaya koyduğu, rakipleri ile arasındaki farkı belirleyen “iş ürünlerinin” korunması önem arz etmektedir. Rakiplerin birbirini yenme arzusu; piyasa katılımcılarının yılların deneyimi ile fikri çaba ve emeğin bir araya getirdiği iş ürünlerinin korunmasını önemli kılmaktadır. Aksi halde serbest rekabet etme hakkı, hukuka aykırı olarak ihlal edilir ve parazit rekabet oluşur. Parazit rekabetin oluşmaması için katılımcıların emeğinin korunması önem arz eder.” Türk Hukuku açısından yeni bir hüküm olan; TTK 55/1-c hükmü sayesinde parazit rekabetin önlenmesi ve “Emeğin Korunması” amaçlanır. Bu çalışmamızda “başkalarının iş ürünlerinden yetkisiz yararlanma” fiilinin, haksız rekabet hükümleri haricindeki hükümler ile ilişkisi ele alınacak ve devamında özel olarak düzenlenen TTK 55/1-c hükmü incelenecektir.Protection of exertion, which constitutes the basis of unfair competition with the new Turkish Commercial Code; It has been taken under the new provision of "unauthorized use of the work products of others". In order to ensure the lawful continuity of competition in a healthy environment, it is important to protect the "work products" that are put forward by the efforts and experience of the competitors and that determine the difference between them and their competitors. The desire of rivals to beat each other; makes it important to protect the work products brought together by years of experience of market participants and intellectual effort and exertion. Otherwise, the right to free competition is violated unlawfully and parasitic competition occurs. It is important to protect the exertion of the participants in order to avoid parasitic competition. As a new provision in Turkish Law; With the provision of TTK 55/1-c, it is aimed to prevent parasitic competition and "Protection of Exertion". In this study, the relationship of the act of “unauthorized use of the work products of others” with provisions other than unfair competition provisions will be discussed and then the specially regulated TCC 55/1-c provision will be examined
Developing session-based personalized accommodation recommender system by using LSTM
No full textTourism sector has been transformed by the advances in the Internet technology. Users can search for information and can select their destination from various alternatives by themselves, which brings the need for personal recommender methods. Personalized recommender system development is a complex topic. Demographic information, series of user clicks, and interactions and hotel features are examined to offer the appropriate set of hotels. Since the user interactions, clicks and hotel history is a time series data, Long Short-Term Memory models is a perfect fit to recommend a set of hotels from this data. In this study, we proposed a session-based accommodation recommender system that uses LSTM and achieved promising results
COVID-19 and the global value chain: Immediate dynamics and long-term restructuring in the garment industry
No full textAdvancing the literature on global value chains (GVCs), this study investigates the impact of the COVID-19 pandemic on immediate dynamics and long-term changes shaping the evolution of the garment GVC. We use a partially grounded, longitudinal approach to analyze data on seven cases of Bangladeshi garment manufacturers, supplemented by archival data on the garment industry. Based on our analysis, we theorize that the COVID-19 crisis has led to three types of dynamics (temporal, structural, and spatial) that contribute to GVC restructuring. Consistent with the paradox approach, we document two counter-tensions that influence the GVC in the long term: the push to disintegrate (i.e., permanently restructure) and the pull to integrate (i.e., preserve or strengthen the existing structural routines). We conceptualize the ultimate structure of the GVC as the alignment of a new balance of power and new capabilities of the GVC actors. Implications for theory, practice, and policy are discussed
The role of learning theory in child-computer interaction - a semi-systematic literature review
No full textIn this paper, we explore the role of learning theory in the Child-computer interaction (CCI) community's leading venues: the Interaction Design and Children (IDC) conference and the International Journal of Child-Computer Interaction (IJCCI). Searching all publications in the IDC conference proceedings and IJCCI, 63 papers that use the word stem ĝ€?FOR VERIFICATION>learn∗' in title, abstract and keywords were included in the corpus. Based on an analysis of these papers, our semi-systematic literature review demonstrates that assessment of learning regarding transfer of learning and controlled groups is rare, that the main role for learning theory is application, and that four main theoretical positions on learning can be recognized: constructivism, constructionism, cognitive theories, and socio-cognitive theory. The paper further presents an overview of how and which learning theories are used, and outlines paths for future CCI research based on the results.European Union’s Horizon 202
Universality and diversity in event cognition and language
No full textHumans are surprisingly adept at interpreting what is happening around them – they spontaneously and rapidly segment and organize their dynamic experience into coherent event construals. Such event construals may offer a starting point for assembling a linguistic description of the event during speaking (Levelt, 1989). However, the precise format of event representations and their mapping to language have remained elusive, partly because research on how people mentally segment and perceive events (see Radvansky & Zacks, 2014 for a review) has largely proceeded separately from analyses of how events are encoded in language (see Truswell, 2019 for a review)
