Opis:
In this work, both hardware and software of a palm vein capture system have been designed and a prototype is produced. By using this system, a genuine database was created with age and gender information of volunteered test subjects. Widely used pre-processing, acquisition of feature vectors, and classification methods were tested on the database and results are compared with speed versus accuracy. All the modules used in hardware and software were determined as open source. Python has been chosen as a software module programming on a single board computer with Linux kernel. As a result, an appropriately running system has been built with both secure software and hardware interfaces having maximum accuracy at 95.33% while specificity is at 100%.

Opis:
In today's world where intensive competition exists between enterprises, it is of great importance to work in cooperation with the right suppliers. Selection of the right suppliers is a significant factor in the success of enterprises. In the selection of the best supplier (s), the strengths and weaknesses of potential suppliers should be taken into consideration. Many qualitative and quantitative criteria are included in this selection process as well as the decision-maker. One of the issues that leaves the decision maker in a difficult position is selecting the most appropriate one from the alternatives available, as traditional methods may not produce a realistic solution in this process. However, multicriteria decision making methods facilitate the process of finding a solution and enable decision makers to reach the right decisions. In this study, the fuzzy TOPSIS method, which is one of the multi-criteria decision making methods, is used in this problem area to select the most appropriate supplier of garment 'X' operating in Turkey. It is detected through analyses conducted in line with the results obtained. The ranking of the three supplier firms determined by firm X are as follows in terms of closeness index values: supplier 1, supplier 3 and supplier 2.
Dla uzyskania powodzenia w prowadzeniu przedsiębiorstw bardzo ważna jest współpraca z odpowiednimi dostawcami. Decyduje o tym szereg kryteriów, które powinny być wzięte pod uwagę. Wybór oparty na tradycyjnych metodach analizy może być trudny i zawodny, dletego też zaproponowano nową multikryterialną metodę doboru opartą na analizie zbiorów rozmytych. Analizę porównawczą przeprowadzono porównując trzech zróżnicowanych dostawców.

Opis:
Turkish textile firms work under a heavily competitive atmosphere in terms of prices due to globalisation. Firms have to take into consideration several criteria in order to survive the global market conditions and to maintain profitability. Contractor companies have to select the optimal subcontractor in order to meet these criteria and in business. Therefore the decision to choose subcontractors is of great importance for the success of enterprises. In solving the problem of subcontractor selection, multiple criteria should be considered, for which multi-criteria decision-making methods are used. This paper presents a case study which regards the selection of the optimal subcontractor for a Turkish textile firm. In order to solve the selection problem generalized Choquet integral methodology was used based on a hierarchical decision model. In the conclusion section of the study, optimal subcontractor selection results are presented.
W wyniku globalizacji przedsiębiorstwa tureckie pracują w warunkach zintensyfikowanej konkurencji, w związku z tym muszą brać pod uwagę zróżnicowane kryteria dla utrzymania się na rynku. Dla spełnienia tych kryteriów dostawcy muszą wyselekcjonować odpowiednich poddostawców. Artykuł przedstawia metody odpowiedniego doboru poddostawców w tureckim przemyśle tekstylnym. W tym celu stosuje się ogólny całkowy model Choqueta. W podsumowaniu pracy przedstawiono optymalne metody selekcji poddostawców.

Opis:
The research was conducted to determine the effects of substituting raw maize with flaked maize in diets containing different levels of metabolic energy on the performance, egg quality, and serum parameters of layer quails. In the experiment, 120 female quails at ten weeks of age were randomly allocated to six treatment groups with four replicates, each consisting of five quails. The quails were fed six diets, with two forms of maize (raw or flaked) and three metabolic energy levels (2750, 2825 or 2900 (control) kcal/kg) during a ten-week trial. Compared with the control group, reducing the metabolic energy level of the diet to 2750 kcal/kg negatively affected egg production (P < 0,01), egg mass (P < 0,01), feed conversion ratio (P < 0,01), and serum cholesterol concentration (P < 0,05). Eggshell thickness decreased significantly in the group receiving 2750 kcal/kg metabolic energy in the diet, and the yolk b* value increased significantly (P < 0,01). The use of flaked maize in the diets significantly increased egg production (P < 0,05), egg mass (P < 0,05), eggshell thickness (P < 0,05), and yolk L* value (P < 0,01) and significantly decreased the feed conversion ratio (P < 0,05) and b* value of the yolk (P < 0,05). Although the effects of the interactions of the metabolic energy levels and forms of maize on the egg yolk b* value were significant (P < 0,01), this effect was not significant for the other parameters. The results indicate that layer quails can be fed diets containing 2825 kcal/kg metabolic energy and that replacement of raw maize with flaked maize in the diet positively affects performance and egg quality.

We presented the results of electrical and optical studies of the properties of $In_xGa_{1-x}N$ epitaxial layers (0.060≤x≤0.105) grown by metalorganic vapour phase epitaxy. Resistivity and Hall effect measurements of the samples were carried out at room temperature. Optical properties of the samples were characterized by photoluminescence and optical absorption spectroscopy. The comparison between the photoluminescence and the optical absorption measurements gives the Stokes shift. We explained the observed Stokes shift in terms of Burstein-Moss effect. The band gap versus composition plot for $In_xGa_{1-x}N$ alloys is well fitted with a bowing parameter of≈3.6 eV.

Opis:
In this study, FeCrC powder was alloyed on the surface of AISI 1030 steel with FeCrC powder having 70% Cr ratio with the Plasma Transferred Arc Welding Method. In the coating process performed with the Plasma Transferred Arc Welding Method, N2 gas at 1-3-5% ratio was added to the shielding gas. The coating layer was analysed using optical microscope (OM), scanning electron microscope (SEM), X-ray diffractogram (XRD) and X-ray energy dispersive spectrometer (EDS). As a result of optical microscope and microstructure analyses, it was determined that the coating layer and the sub-layer were connected to each other metallurgical and there were austenite ( γ), Fe-Cr, Fe23(C)6, and Cr7C3 phase and carbides and CrN in the structure.
W pracy badano nakładanie powłok z proszku FeCrC o zawartości 70% chromu na powierzchni stali AISI 1030 metodą PTA. W czasie nakładania powłoki zawartość azotu w gazie ochronnym wynosiła 1, 3, 5%. Uzyskane powłoki badane były za pomocą mikroskopii optycznej, skaningowej mikroskopii elektronowej, dyfrakcji rentgenowskiej i mikroanalizy rentgenowskiej. W oparciu o wyniki obserwacji i analiz mikrostruktury stwierdzono, że powłoka i warstwa pośrednia połączone są ze sobą metalurgicznie. Stwierdzono obecność austenitu, Fe-Cr, Fe23(C)6, Cr7C3 oraz węglików i CrN w mikrostrukturze.

Opis:
In tile manufacturing, α-Al₂O₃ is the main type of alumina used in ceramic body and glaze formulations. This raw material acts as an opacifier in porcelain tile bodies and as a matting agent in glazes. White fused alumina (WFA) is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. It is usually employed in floor tile glazes in order to increase their abrasion resistance. The aim of this study was to establish a better understanding of how alumina and white fused alumina addition affects the thermal behavior and aesthetic properties of wall and floor tile transparent glazes. It was shown that both alumina and fused alumina increased the softening temperatures of the standard glaze composition. Corund was the main detected phase in tile glazes incorporated with fused alumina. This result suggested that white fused alumina did not react with glassy phase to form any other crystalline phases. This result can be attributed to higher refractoriness of white fused alumina. Presence of anorthite and gahnite phases was, on the other hand, observed in the glazes with alumina addition. It was further shown that alumina was more effective in increasing opacity and reducing glossiness compared to white fused alumina.

Opis:
In this study, inhibitor effects of thymol and carvacrol were investigated in vivo and in vitro on acetylcholinesterase enzyme of Drosophila melanogaster. IC₅₀ values, Ki constants and inhibition types were determined for the substances displaying inhibitory effect. In vivo studies, were performed on larvaes by considering IC₅₀ values. The surviving and mortality rates were determined for the solution applied to larvaes. IC₅₀ values of thymol and carvacrol were found to be 25 mM and 0.175 mM, respectively. By using Lineweaver-Burk graphs, it was found that both compounds show non-competitive type of inhibition. According to results, it was concluded that carvacrol is a more effective inhibitor than thymol. We believe that these findings will contribute to the development of more potent, specific and effective inhibitors against AChE enzyme, design of new drugs for treating Alzheimer's disease and studies in pharmacological applications.

High order and non-linear effects in accelerator beamline play an important role in the transport of the beam. These effects cause variation of designed beam parameters such as emittance growth, bunch length variation, beam halo formation, etc. One of the known non-linear effects in bunch compressors is the coherent synchrotron radiation effect. In this study we focus on coherent synchrotron radiation effect in Turkish Accelerator and Radiation Laboratory in Ankara (TARLA) machine which is designed to drive Infrared Free Electron Laser, covering the range of 3-250 μm. We additionally discuss high order effects in bunch compressor of TARLA.

Opis:
Polypyrrole (PPy) coated cotton yarns were prepared by the vapour phase polymerisation technique at various initiator concentrations. Iron (III) chloride (FeCl3) was used as the initiator at four different concentrations (0.2, 0.4, 0.6 & 0.8 mol/l) respectively. In this work, the effects of initiator concentration on the tensile, electrical and morphological properties of the cotton yarns were investigated. PPy coated cotton yarns were woven on a handloom for the investigation of electromagnetic shielding effectiveness. The fabric samples prepared were evaluated in terms of shielding behavior. Scanning electron microscopy (SEM) analysis showed that the yarn treated with 0.4 mol/l initiator concentration gave the most uniform PPy layer and highest shielding value. The existence of PPy was proved by using Fourier transform infrared spectroscopy (FTIR) analysis.
Bawełniane przędze pokryte polipyrolem (PPy) wytworzono techniką polimeryzacji w fazie gazowej w różnych stężeniach inicjatora. Jako inicjator zastosowano FeCl3 o czterech różnych stężeniach (0,2; 0,4; 0,6 i 0,8 mol/l). Zbadano wpływ stężenia inicjatora na rozciąganie, oraz elektryczne i morfologiczne właściwości przędz bawełnianych. W celu zbadania efektywności ekranowania pola elektromagnetycznego przędze bawełniane powlekane PPy były tkane ręcznie na krośnie. Przygotowane próbki tkanin oceniano pod względem właściwości ekranujących. Analiza SEM wykazała, że z przędzy z dodatkiem inicjatora o stężeniu 0,4 mol/l uzyskano najbardziej jednolitą warstwę PPy i najwyższą wartość ekranowania. Obecność PPy potwierdzono za pomocą spektroskopii w podczerwieni z transformacją Fouriera (FTIR).

Hydroxyapatite $[HA; Ca_{10}(PO_4)_6(OH)_2]$ which composes inorganic phase of bones and teeth is one of the biomedical materials for artificial bone, reconstruction of broken or disordered bones, coating of metallic biomedical materials and dental surgery with its great biocompatibility. In this study, HA powders were synthesized from aqueous suspensions containing $H_3PO_4$ and $Ca(OH)_2$ with 1.67 Ca/P ratios (chemical HA, CHA) and second process is carried out in simulated body fluids consisting of $(NH_4)_2HPO_4$ and $Ca(NO_3)_2 \cdot 4H_2O$ as biomimetic hydroxyapatite (BHA). Moreover, properties of bovine HA (BoHA) and commercial HA (CoHA) were compared with properties of synthesized HA powders. Chemical structures of synthesized powders have been examined by the Fourier transform infrared technique and X-ray diffraction. The results showed that BHA powders have a pure HA content and no secondary phase, CHA also has monetite phase as secondary phase with HA in its structure. Particle size analysis was carried out with laser particle sizer and zeta-sizer, surface area of powders has been analyzed by the Brunauer-Emmett-Teller technique. Powder morphology is determined using scanning electron microscopy. As a result two different synthesis methods affected properties of HA powders.

Opis:
Natural resources have been decreasing with the large expansion of the world's population. In order to supply raw material for production, new recycling approaches should be developed for waste materials. Worn shoes is one of the most common waste products that can be recycled for this purpose. According to the record, shoes are very complex products, as they can be produced from forty different materials, like leather, rubber, polymers etc. Especially the bottom layers of the shoes are made from sound absorbing materials like polyurethane, thermoplastic rubber and PVC. Because today's technology is not able to separate these materials from each other during recycling, they should be used in a homogenised state. Thus these parts were shredded into small granules and mixed. PU binder and hot press were used to obtain samples for tests. In this paper sound absorption, sound isolation, vibration isolation and thermal insulation properties of the tread mixture are investigated. In addition to that, the mechanical properties of the material were also investigated by measuring the compression strength of the material.
