Opis:: A robot is an electromechanical system, which is guided by software via electronic circuitry. In the absence of electronic systems, there is no way to make a connection between software and mechanical components. This means that all robotic systems require mechanical systems, electronic systems and software. OMNIMO, as a modular reconfigurable robot, has sophisticated electronic systems and software. Electronic system of OMNIMO includes controllers, actuators, transducers, communication units, regulators, batteries, user interface units and complementary components. In addition, OMNIMO is controlled by four different layers of software. In this paper, electronic hardware details, system integration and control software architecture of modular reconfigurable robot module OMNIMO are presented. In addition, adaptation of components and communication protocol details of hardware are given.

Opis:: In this study, structural or physical properties such as the unevenness, hairiness and frictional properties of cotton-modal blended yarns were studied. For this purpose, 100% cotton, 50/% cotton/modal and 100% modal ring spun yarns were produced in five different twist coefficients (αe: 3.5, 3.7, 4.0, 4.2, 4.5) and four different yarn linear densities (21, 25, 30 and 37 tex). General factorial design was used and the response surface was plotted for analysing the data. In conclusion, the most influential factors for the yarn characteristics were the yarn linear density and blend ratio. Contrary to expectations, the twist coefficient factor had a minor effect on yarn characteristics, especially on the friction coefficient.
W pracy badano właściwości strukturalne i fizyczne, takie jak nierównomierność, włochatość i właściwości cierne przędz bawełnianych. W tym celu wytworzono przędze obrączkowe o różnym stosunku mieszanki: 100% bawełna; 50% bawełna/50% modal i 100% modal z pięcioma różnymi współczynnikami skrętu (αe: 3,5; 3,7; 4,0; 4,2; 4,5) i czterema różnymi masami liniowymi (21, 25, 30 i 37 tex). Dokonano charakterystyki tarciowej poszczególnych przędz. Stwierdzono, że czynnikami mającymi największy wpływ na charakterystykę tarciową były masa liniowa i stosunek mieszanki przędzy. Wbrew oczekiwaniom współczynnik skrętu miał niewielki wpływ na charakterystykę tarciową przędzy, a zwłaszcza na współczynnik tarcia.

Opis:: PbWO₄ crystal-Hamamatsu S8148 avalanche photodiode (APD) assembly has been used in the barrel section of the CMS electromagnetic calorimeter. The shot noise of the photodiode is one of the important parameters for the energy resolution of the crystal-APD system. The major source of this noise is the statistical variations in the rate at which primary charge carriers are generated and recombine. Thus, the shot noise varies with position of the primary charge carriers generated in photodiode. In this work, the shot noise properties of the Hamamatsu S8148 APD structure and zinc sulfide-silicon (ZnS-Si) isotype heterojunction APD structure have been compared for the PbWO₄ photons. Calculations were made with a Single Particle Monte Carlo simulation technique.

Opis:: The long-ranging Early to Middle Triassic coniform conodont form-genus Cornudina Hirschmann occurs abundantly in the Anisian of NW Turkey, Northern Tethys. Although suggested to represent the P1 element of an apparatus of the Order Ozarkodinida Dzik, questions concerning the apparatus of Cornudina remain. A description of the probable phylogenetic trends in the P1 elements of Cornudina is attempted and the role of the form-genera Ketinella Gedik and Kamuellerella Gedik, as the alternative ramiform skeletal elements in the Cornudina multi-element apparatus, is investigated. The newly described, Gedikella quadrata gen. nov., sp. nov., is an S element, Kamuellerella rectangularis sp. nov., is either an S3 or an S4 element, and Ketinella goermueshi sp. nov., is an M element.

Opis:: The purpose of this study is to investigate the use of İzmir (Menderes-Cumaovası) expanded perlite as a construction raw material by determining its characteristic properties, as well as its physical properties at different temperatures (up to 600°C). The perlites, having glassy, porous structure, were found to contain 70.68% SiO2 and 13.04% Al2O3. The physical properties of the perlites changed with temperature. The highest surface area, 524 m2/g, was obtained at 400°C. The physical properties were found to have high statistical relation. It was concluded that expanded perlite aggregates could be used as a construction raw material.

Opis:: The proposed particle factory detector for Turkish Accelerator Center (TAC-PF) being a regional facility in Turkey will operate at the center of mass energy about 3.77 GeV with designed luminosity of the order of 10³⁴ cm¯² s¯¹. The electromagnetic calorimeter part of the detector is considered to have PbWO₄ and CsI(Tl) crystals coupled with photodiodes. In this study, the exposed dose rate to electromagnetic calorimeter during PF detector operation was estimated by FLUKA Monte Carlo tool. The irradiation effects such as the change of light yield and light transmission of these crystals were investigated to evaluate TAC-PF electromagnetic calorimeter energy resolution.

Opis:: The effect of square wave current was investigated by the voltage-time (V-t curves) measurements at various external magnetic fields and periods (P) in silver doped YBCO. The general sinusoidal behavior of V-t curves was mainly interpreted as a dynamic competition between driving and pinning forces. It is observed that as the period of square wave current is increased, the amplitude of oscillation is also increased. The observed oscillations in the voltage was fitted by an common sinusoidal equation V(t)ımın(ω t+φ). It is also found that there is different phase angle φ values for each cycle. Fast Fourier transform measurements is applied to oscillation period (P_{I}) of the square wave current. The results give us that a physical mechanism is related with charge density waves. Intrinsically, in Ag doped YBCO, the pinned flux line system evokes the general behavior of charge density waves. Due to properties of the converting the square wave current to sinusoidal voltage oscillations, Ag doped YBCO sample can behave as double-integrator for the defined period, amplitude of square wave current and magnetic field values in time.

Opis:: In this paper, characterization of fly ashes obtained from the Yatagan Thermal Power plant, Mugla, Turkey was performed in order to determine their radioactive element contents, especially uranium and thorium. The representative fly ash samples were subjected to hydrochloric acid (HCl) leaching considering solid concentration, acid dosage, leaching time and temperature in order to reach certain uranium and thorium recoveries. The obtained results showed that the optimum conditions for leaching tests were: 30% solid concentration, 2.36 mmol/dm3 HCl addition, 240 min leaching time and 40 oC temperature. Dissolution efficiencies for uranium and thorium from the Yatagan Thermal Power Plant fly ashes were calculated as 90.12 and 81.18%, respectively.

Opis:: Outstanding properties of sintered ceramics due to lower sintering temperatures and smaller grain sizes are of much attention to many researchers. In this study, YAG phase was formed successfully with mechanical activation of powder mixtures by high energy ball milling of powders at different speeds. The powders were compacted and sintered at three different temperatures to evaluate the sintering density, phase formation and grain formation. It was found that increasing activation time, which agitates the powder mixing more accurately, has led to an increase in the relative density, as compared to non-activated samples, sintered at same temperatures. Up to 95% ot the theoretical density were reached, indicating the partial liquid phase formation of Y-A related phases. YAG phase formation and crystallite size were evaluated using XRD and Debye-Scherrer formula. The studies of grain size and surface morphology were conducted using SEM. Since the mechanical activation of ceramic powders occurs by fragmentation and crack propagation, by brittle fracture of powders, the main mechanism of reduction of sintering temperature can be concluded to be the decreasing grain size, as well as the increasing strain on fine powder grains.
