Allied closed-loop supply chain network optimization with interactive fuzzy programming approach

ÇALIK, Ahmet | PEHLİVAN, Nimet Yapıcı | PAKSOY, Turan | KARAOĞLAN, İsmail

The concept of closed-loop supply chain (CLSC) has started to attract growing attention due to the consumer pressures, environmental awareness, and legislations. Managers in many companies have realized that a well-designed supply chain (SC) can improve the companies’ performance in the market. Thus, a lot of companies start to focus on CLSC issues including remanufacturing, refurbishing, recycling, and disposal of end-of-life products. The body of literature on CLSC management has been overwhelmingly dominated by noncooperative studies. In order to fill up this gap in the literature, we deal ...Daha fazlası

Investigation of the Mantle System Applied to Outer Shell of Apartment Buildings in Terms of Energy Efficiency (Erzincan Case)

ÇAĞLAR, Arzu | ÇAĞLAR, Hakan | KOÇU, Nazım | YAZICIOĞLU, Salih

Energy is a phenomenon that leads to conflicts, internal conflicts, and antagonism in all areas of life. Considering that we are dependent on foreign countries in the field of energy, the conservation of energy is getting more and more important day by day. A large portion of the energy consumed in Turkey is used to heat houses. It is very important to maintain the heat and keep it on the field as well as to heat the house. It is seen that the best and economical way of keeping the heat is thermal insulation in the apartments. In this study, five apartments in Erzincan which is in the 4th grad ...Daha fazlası

Estimation of long-term monthly temperatures by three different adaptive neuro-fuzzy approaches using geographical inputs

KİŞİ, Özgür | DEMİR, Vahdettin | SUNGWON, Kim

This paper investigates the accuracy of three different adaptive neuro-fuzzy inference systems (ANFISs), ANFIS with grid partition (ANFIS-GP), ANFIS with substructive clustering (ANFIS-SC), and ANFIS with fuzzy c means (ANFIS-FCM) in estimation of long-term monthly air temperatures. Data of 71 stations in Turkey are used in the applications. The periodicity (month of the year) and geographical variables (latitude, longitude, and altitude) are used as inputs to the models. ANFIS models are also compared with artificial neural networks (ANNs) and multilinear regression (MLR). Three ANFIS methods ...Daha fazlası

Biomechanical comparison of transdiscal fixation and posterior fixation with and without transforaminal lumbar interbody fusion in the treatment of L5–S1 lumbosacral joint

ÖZALP, Hakan | ÖZKAYA, Mustafa | YAMAN, Onur | DEMİR, Teyfik

Transdiscal screw fixation is generally performed in the treatment of high-grade L5–S1 spondylolisthesis. The main thought of the study is that the biomechanical performances of the transdiscal pedicle screw fixation can be identical to standard posterior pedicle screw fixations with or without transforaminal lumbar interbody fusion cage insertion. Lumbosacral portions and pelvises of 45 healthy lambs’ vertebrae were dissected. Animal cadavers were randomly and equally divided into three groups for instrumentation. Three fixation systems, L5–S1 posterior pedicle screw fixation, L5–S1 posterior ...Daha fazlası

Impact of Industry 4.0 Revolution on Science, Technology, and Society (STS): Challenges and Opportunities in the Industry 4.0 Era

ULUSOY, Tuba | YAŞAR, Esra | AKTAN, Mehmet

The Industry 4.0 concept, which leads the Fourth Industrial Revolution, was introduced by Germany in 2011 at the Hannover Messe trade fair and attracted the attention of the world. Since that time, its effects have been seen in different fields, such as science, technology, and society. In this chapter, in order to investigate the effects of Industry 4.0 revolution, answers to the following questions will be presented: Are there any concerns about technological unemployment as a result of Industry 4.0. revolution? Which professions have emerged? How has Industry 4.0 affected society directly o ...Daha fazlası

Recent resonance results measured with the ALICE detector at the LHC

YALÇIN, Serpil | KARASU UYSAL, Ayben | ALICE Collaboration

Resonances are extremely short lived particles (τ ∼ 10-23 s). Due to their lifetime, they may decay, re-scatter and regenerate between chemical and kinetic freeze-outs. For this reason, they are very significant probes to understand the evolution of the medium and particle production mechanism in heavy ion collisions. Different than other particles, resonance properties such as mass, width and yield can be modified by the medium created in the relativistic collisions. Moreover, comparison of resonances produced in different collisions provide evidences about possible in medium effects and syst ...Daha fazlası

Comparison of rigid and semi-rigid instrumentation under acute load on vertebrae treated with posterior lumbar interbody fusion/transforaminal lumbar interbody fusion procedures: An experimental study.

ÖNEN, Mehmet Reşid | BAŞGÜL, Cemile | YILMAZ, İlhan | ÖZKAYA, Mustafa | DEMİR, Teyfik | NADERİ, Sait

Rigid and semi-rigid fixations are investigated several times in order to compare their biomechanical stability. Interbody fusion techniques are also preferable for maintaining the sagittal balance by protecting the disk height. In this study, the biomechanical comparison of semi-rigid and rigid fixations with posterior lumbar interbody fusion or transforaminal lumbar interbody fusion procedures is conducted under trauma. There were four different test groups to analyze the effect of acute load on treated ovine vertebrae. First and second groups were fixed with polyetheretherketone rods and tr ...Daha fazlası

Comparison of methods in FAHP with application in supplier selection

YAPICI PEHLİVAN, Nimet | PAKSOY, Turan | ÇALIK, Ahmet

Green supply chain management (GSCM) is described as the combination of environmental thinking and supply chain management (SCM) encompassing product design, material sourcing and selection, manufacturing processes, delivery of the nal product to the consumer, and endof-life management of the product (Srivastava, 2007; Tseng and Chiu, 2013). Environmental sustainability of a supply chain depends on the purchasing strategy of the supply chain members. Most of the supply chain models focus on cost, quality, lead time, carbon emission, etc., issues for supplier selection. Shaw et al. (2012) prese ...Daha fazlası

On the Interpretation of Melt Quality Assessment of A356 Aluminum Alloy by the Reduced Pressure Test: The Bifilm Index and Its Physical Meaning

ULUDAĞ, Muhammet | ÇETİN,Remzi | DIŞPINAR, Derya | TİRYAKİOĞLU, Murat

The oxide layer on liquid aluminum serves as a protective property to prevent the alloy from further oxidation. However, it has the potential to be a source of porosity when entrained into the bulk of the liquid. For this reason, oxides entrained into aluminum castings have been shown to degrade casting quality. In the current study, the effectiveness of the reduced pressure test in assessing the quality of A356 alloy melts has been investigated under various conditions obtained by changing six different melt parameters. Several metrics, including average pore size, number density of pores, bi ...Daha fazlası

A 3D face animation system for mobile devices

MENDİ, Engin

In this paper, we present a 3D face animation system rendered on mobile devices. The system automatically creates realistic facial animation from text input with emotion tags. First, an input string is converted into synthetic voice and phonetic information. Then, 3D head model performs facial movements synchronized to the speech. The proposed system offers an affordable quick solution for applications that require virtual actors speaking text in which human-machine interfaces on mobile devices can profit.
