A Decision support system for machine tool selection

Business globalization, increased worldwide competition, decreased product lifecycles and continuous introduction of new technologies force companies to use new machine tools. Appropriate selection of a machine tool for a production system resultsin increased precision, productivity, flexibility, and manufacturing responsiveness.Meanwhile, machine tool selection is a multi-faceted manufacturing planning problem,typically involving a variety of conflicting goals. Thus, selecting the most suitablemachine from the increasing number of available machines is a difficult and demandingtask. In this thesis, a decision support system (DSS) is developed to aid in selection of machine tools for a production system. The DSS uses multi-criteria weighted averagemethod (MCWA) as the decision-making approach. MCWA method considers a set ofconflicting objectives such as productivity, flexibility, and adaptability that typically cannot be achieved simultaneously. Each machine tool is assigned a score according to itsproperties in relation to the machines in the database. These scores are then used to rankthe machines according to various criteria. A stepwise approach is used in the selectionprocess. The entire tool selection process is demonstrated with examples. Sensitivity analysis is used to determine the most critical criterion and the most critical measure ofperformance. Cost / benefit analysis is carried out involving the purchasing decision of aselected machine tool and its additional options

The concept of obedience in Uigur and Karakhanid Turkish.

TEZ12535Tez (Yüksek Lisans) -- Çukurova Üniversitesi, Adana, 2016.Kaynakça (s. 246-251) var.xii, 252 s. ;_29 cm.Devlet sisteminin iki önemli unsuru yöneten ve yönetilendir. Yönetilenin, yönetene “itaat etmesi” bu sistemin en temel özelliklerindendir. Tıpkı siyasî anlamda olduğu gibi, dinî anlamda da “itaat kavramı”, sistemin merkezinde yer alır. İnananın “gönüllü bir şekilde” yaratıcıya itaat etmesi gerekir. Bütün dinlerin ve devlet sisteminin merkezinde yer alan bu kavram, bilinen en eski dönemlerde Türk töresinin de değişmeyen önemli bir unsurudur. Huastuanift, Irk Bitig ve Manihaist Uygur Metinleri adlı Manihaist Uygur edebiyatı dönemi eserlerinin, Altun Yaruk, Hsüan-Tsang Biyografisi ve Üç İtigsizler adlı Budist Uygur edebiyatı dönemi eserlerinin ve Kutadgu Bilig, Atebetü’l-Hakayık ve Türkçe İlk Kur’an Tercümesi (Rylands Nüshası) adlı Karahanlı (Hakaniye) Türkçesi dönemi eserlerinin söz varlığında, itaat kavram alanını oluşturan sözcükleri tespit ederek, bu kavram alanının varlığının ilk kez belirlenmesi ve bu dönemdeki düşünce dünyasında itaatin yerinin ortaya çıkarılması temel amacımız olmuştur. Öncelikle Uygur ve Karahanlı devletleri, onların inançları ve eserler hakkında bilgiler, daha sonra ise kesin bir tanımı henüz yapılamayan “kavram” ve çalışmamızın teorik temelinde yer alan “sözlüksel alan (kavram alanı) teorisi” hakkında bilgiler verilmiştir. Daha sonra ise itaat kavramı kısaca açıklanmıştır. Son olarak eserlerde tespit edilen ve itaat kavram alanını oluşturan bütün sözcükler farklı anlam kategorilerinin bulunduğu tablolar hâlinde sınıflandırılmış ve tüm bu verilere dayanarak çeşitli sonuçlara ulaşılmıştır.The ruling and the ruled are two important elements of the system of a state. Obeying the ruling is one of the fundamental qualities of this system. Also in religious meaning, the concept of obedience is situated in the centre of the system, just as it is in political meaning. It is necessary for believers to obey the creator willingly. This concept, situated in the centre of all religions and the systems of the state, is an important and invariable element of the oldest known periods of Turkish law. Determining the words formed the conceptual field of obedience on the vocabulary of Manichaean Uigur works named Huastuanift, Irk Bitig and Manichaean Uigur Texts; on the vocabulary of Buddhist Uigur works named Altun Yaruk, The Biography of Xuanzang in Old Uigur and Uc Itigsizler; and on the vocabulary of Karakhanid Turkish works named Kutadgu Bilig, Atebetu’l-Hakayık and First Turkish Kor’an Translation (The copy of Rylands), it has been our principal aim to determine the presence of this conceptual field firstly and to reveal the place of obedience in the mentality of this period. Initially the formations about the states of Uigur and Karakhanid, their beliefs and works, then the formations were given about “concept”, not identified completely yet, and the lexical field (conceptual field) theory situated in the theoretical base of our work. Later, the concept of obedience was explained briefly. Finally, all words determined in the works and formed the conceptual field of obedience were categorized as tables including different meaning categories and gained some kind of conclusions regarding all information

Taxing policy in cigarette marketing with in the context of financing of terrorism

Sigara uyuşturucu madde, silah ve insan kaçakçılığına kıyasla daha masum olan yönüyle, kaçakçılığı yapılan ancak suçla mücadele birimlerinin üzerine yeterince eğilmedikleri bir ticari maldır. Bu nedenle sigara kaçakçılığı son dönemde terör örgütleri ve organize suç gruplarının finansal kaynak amacıyla yoğun biçimde işledikleri suç türleri arasına girmiştir. Bu tez çalışmasının amacı, sigara vergi politikalarının bireylerin sigara tüketim davranışları üzerindeki etkisini, kaçak sigara ve terörün finansmanı bağlamında ortaya koymaktır. Araştırma nicel yöntemle gerçekleştirilmiş olup, araştırmanın verileri tesadüfi örneklem yöntemiyle Ankara kent merkezinde derlenmiştir. Katılımcıların Ankara kent merkezinde yaşayan 18 yaş üstü yetişkinlerden oluşması kısıtlar arasındadır. Araştırmada elde edilen temel bulgulara göre kaçak sigara kullanım algısı cinsiyet, meslek, eğitim düzeyi, yaş, aylık gelir düzeyi, sigara kullanım sıklığı ve kullanım süresi değişkenlerine göre farklılık göstermektedir. Sigaraya yapılan fiyat artışlarına karşı tutumlar cinsiyet ve yaşa göre farklılık göstermemektedir.Cigarette is a commercial commodity that is smuggled but not sufficiently focused on by law enforcement units, with its more innocent aspect compared to drugs, weapons and human smuggling. For this reason, cigarette smuggling has recently become one of the types of crimes that terrorist organizations and organized crime groups commit intensively for financial resources. This dissertation aims to reveal the effect of cigarette tax policies on individuals' cigarette consumption behaviors in the context of illegal cigarettes and financing of terrorism. The research was carried out with the quantitative method, and the data were gathered by random sampling method in the city center of Ankara. Consisting of adults over the age of 18 living in the city center of Ankara is among the restrictions. According to the basic findings of the research, the perception of illegal cigarette using differs according to the variables of gender, occupation, education level, age, monthly income level, frequency of smoking and duration of use. Attitudes towards price increases for cigarettes do not differ according to gender and age

A decision support system for machine selection

Globalization of business, the worldwide competitive economy and the decrease in product life force companies to use new equipments that are continuously introduced to the market with the advances in technology. An improper selection can negatively affect productivity, precision, flexibility and company’s responsive manufacturing capabilities. Thus, selecting the most suitable machine from the increasing number of available machines can be highly demanding. A decision support system is developed for the selection of machine tools. It will guide the selection process and help a decision maker solve the selection problem. Multi-criteria weighted average is used in decision-making process to rank the machines evaluated with respect to several criteria. The method is demonstrated with an example

Assessing population status and conservation of endangered Marmaris salamander, Lycisalamandra flavimembris (Mutz and Steinfartz, 1995), in Southwestern Turkey

International audienceThe Marmaris salamander is an endemic and endangered amphibian species in Southwestern Anatolia. Here, we estimated some population parameters of Marmaris salamander by conducting 40-day intensive fieldworks in between 2017-2019. We marked 323 salamanders and recaptured 46 of them. The population consists of % 36 in juveniles % 28; in males; and % 36 in females and female-biased sex ratio (m: f= 0.77) was observed. Population size was calculated between 73 and 295 individuals. The capture probability ranged from 0.15 to 0.54 and the survival rate ranged from 0.53 to 0.86 among the populations. The potential distribution area could narrow between 9% and 62% in the next 30-50 years. The most important threats are land convention, climate change, and forest fires. If no action is taken, it could relatively restrict the narrow area and some populations might go extinct

Oligomerization and cell surface expression of recombinant GABA(A) receptors tagged in the delta subunit

The gamma-Aminobutyric acid type A receptors (GABA(A) Rs) are heteropentameric chloride channels responsible for primary inhibition in the mammalian brain. Studies have shown the expression of recombinant GABA(A) R subunits tagged with the green fluorescent protein (GFP), a 26.9 kDa protein that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. This allows the formation of recombinant proteins essential for the development of relevant in-vitro and in-vivo methodologies. Among the GABA(A) R subunits, the delta subunit was never tagged in its cytoplasmic domain, an evolutionary conserved domain found in between the third and the fourth transmembrane domains. In this study, first, we have cloned the mouse cDNAs encoding for the delta, alpha 1, beta 2 subunits of GABA(A) Rs, and then developed two fusion proteins of delta subunit each tagged with the GFP variant, EGFP (enhanced GFP) at unique sites in the cytoplasmic domain. The recombinant proteins were expressed alone or in combination with alpha 1 and/or beta 2 subunits in neuroblastoma 2a cells. Live cell confocal microscopy indicated that the cytoplasmically tagged delta subunits were targeted to the cell membrane when expressed in the presence of alpha 1 and beta 2 subunits in neuroblastoma 2a cells. However, this was not observed when they were expressed alone or only with alpha 1 or beta 2 subunits in the same cell line. These results confirm the general oligomerization and targeting pattern of GABA(A) R subtypes described in the other in vitro studies in the literature. Thus, our results suggest that the EGFP tagging in the ctoplasmic domain did not interfere with the oligomerization and cell surface expression of recombinant delta subunits. To our knowledge, this is the first study showing the generation, expression and preliminary analysis of the delta-GABA(A) Rs tagged in the cytoplasmic domain of the delta subunit which can be further elaborated to probe intracellular protein interactions of GABA(A) Rs via the delta subunit

Distribution and current status of herpetofauna in the Gediz Delta (Western Anatolia, Turkey)

International audienceIn this study, we conducted an inventory of amphibians and reptiles between 2013 and 2016 in the Gediz Delta (İzmir, Turkey). The field results were combined with existing records. According to the data obtained, a total of 35 herptile species live in the region, comprising 7 amphibians (2 urodeles, 5 anurans) and 28 reptiles (6 chelonians, 10 lizards and 12 snakes). Five species (Lissotriton vulgaris, Triturus ivanbureschi, Heremites auratus, Platyceps collaris and Telecopus fallax) were recorded for the first time in the Gediz Delta during the study. A chorotype classification and potential threats of the species are also presented
