In this study, a new electrooculography (EOG) based system that provides efficient communication for people suffered from motor neuron diseases is presented. The system consists of two distinct devices. The first device operates as a main unit that is activated by the subject’s eye movements. This unit is capable of transmitting 10 different command/state messages. These messages enable subject to choose his/her situation such as “I’m fine”, “I feel bad”, “I’m hungry” and “I’m thirsty”. Commands such as “Come”, “Go”. The number of messages can be increased. The main unit acquires the EOG signa ...Daha fazlası
Smart home energy scheduling problem is a significant subject in power system to avoid extra expenditure. In this work, the scheduling problem is realized using mixed integer linear (MILP) programming and simulated annealing (SA) method. MILP is one of the integer optimization method and SA is a strong technique for solving hard combinatorial optimization problems. Various types of electricity tariff is applied from country to country. In Turkey, one term and three term tariffs (electricity prices are divided into three parts; off-peak hours, mid-peak hours on-peak hours) are used. In this stu ...Daha fazlası

In this study, a photo-bioelectrochemical fuel cell was constructed for photocurrent generation by illuminating the electrodes within an aqueous solution. In this purpose, gold electrode was coated with poly 4-(4H-Dithieno [3,2-b:2′,3′-d]pyrol-4-yl) aniline, P(DTP-Ph-NH2) conductive polymer fi lm by using electrochemical polymerization. Then, P(DTP-Ph-NH2) conductive polymer fi lm coated surface was electrochemically modi fi ed with cytochrome C which covalently linked onto the surface via bis-aniline functionality of the polymer fi lm and formed crosslinked-structure. The thylakoid membrane was a ...Daha fazlası

Hyperhidrosis (HH) is a pathological condition of excessive secretion of the eccrine sweat glands in amounts greater than that required for physiological needs. Herein, we describe a patient who was treated with autologous blood pleurodesis for ductus thoracicus injury after endoscopic thoracic sympathectomy. A 23-year-old woman was admitted to our clinic with a complaint of bilateral pronounced axillary HH, minimal sweating of the hands, and bruising. She underwent bilateral thoracic sympathectomy at levels T3 and T4. A milky fluid was observed in the left chest tube and was diagnosed as chyl ...Daha fazlası
In this study, an amperometric cholesterol biosensor was constructed based on cholesterol oxidase immobilized on a conducting 4-(4H-dithienol[3,2-b:2’,3’d]pyrrole-4)aniline polymer, (DTP(aryl)aniline). Glassy carbon electrodes were covered with P(DTP(aryl)aniline) which is used for the wiring of enzyme to the electrode surface by using electro-polymerization. The electron transfer was successfully made by the bio-catalytic activity and possession of the unique morphology of the polymer allowed efficient immobilization of the cholesterol oxidase enzyme. Analytical performances, linear range, de ...Daha fazlası
Abstract BACKGROUND: Recent reports have described inherent problems with androgen immunoassays compared with mass spectrometry analyses. In this study, a new liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed according to CLSI rules. The developed method was compared with two immunoassay methods, the enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA). METHODS: After liquid-liquid extraction, a Shimadzu Prominence LC unit coupled to an ABSCIEX API 3200 mass spectrometer with atmospheric pressure chemical ionization was used to quantify serum andros ...Daha fazlası

The effect of melt quality on hot tearing susceptibility of Al8Si3Cu alloy was examined under six different conditions, by using a traditional T-shaped mold. Grain refinement was carried out by two different modifiers: AlTi5B1 and Al3B. For each test, samples were cast before and after degassing of melt. Therefore, a new hot tearing tendency index was developed by both bifilm calculations and porosity that occurred in the middle of T-zone of casting parts. Results indicated that hot tearing of cast aluminum alloys was a complex phenomenon, and bifilms play a major role, especially by compensat ...Daha fazlası
Inclusive J/ψ production is studied in p-Pb interactions at a centre-of-mass energy per nucleon-nucleon collision sNN−−−√=8.16 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, via its decay to a muon pair, in the centre-of-mass rapidity intervals 2.03< ycms< 3.53 and −4.46< ycms< −2.96, where positive and negative ycms refer to the p-going and Pb-going direction, respectively. The transverse momentum coverage is pT< 20 GeV/c. In this paper, ycms- and pT-differential cross sections for inclusive J/ψ production are presented, and the corresponding nuclear modificati ...Daha fazlası

After a brief introduction, this chapter discusses the state of the art of variable antennas and previous works on these antennas are reviewed. This is followed by an introduction to the most common statistical analysis techniques used for the purpose of the uncertainty propagation. The application of the statistical method to some real case structures is then considered; split ring resonator (SRR) and wearable antennas.

Closed-Loop Supply Chain (CLSC) management has attained appreciable attention over the last few years. CLSC management allows companies to manage their recovery and recycling activities of end products. Due to the latest developments in the world, producers are responsible for the collection, refurbishing, repairing and disassembly of end products at the end of their lives. This paper develops a mixed-integer CLSC model that is inspired by the automotive industry. In this model, we consider three Decision Makers (DM): Plant, Dismantler Center and Customer. Each DM has individual objectives and ...Daha fazlası
In this paper, we propose an approach for modeling claim dependence, with the assumption that the claim numbers and the aggregate claim amounts are mutually and serially dependent through an underlying hidden state and can be characterized by a hidden finite state Markov chain using bivariate Hidden Markov Model (BHMM). We construct three different BHMMs, namely Poisson–Normal HMM, Poisson–Gamma HMM, and Negative Binomial–Gamma HMM, stemming from the most commonly used distributions in insurance studies. Expectation Maximization algorithm is implemented and for the maximization of the state-de ...Daha fazlası

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
