    The effect of using phase change materials and examining the aspect ratio in an air-cooled system of a plate battery connected to a solar system

    Akkurt, Nevzat

    Lithium-ion batteries are widely used in the electronics industry to store electrical energy. One of the challenges with these batteries is that they heat up during operation, which can damage the battery. For this reason, this paper simulates the cooling process of a plate-type (BTP) lithium-ion battery pack. To control the temperature of the battery (T-B), a laminar air flow and a phase change material (PCM) are used. The PCM is placed in a heat sink around the battery. This evaluation is performed temporarily for four different dimensions of the PCM pack. The hot outlet of this system is used to provide the thermal energy required for a small residential building (THE) at a mild temperature. The BTP was also simulated using COMSOL. The results show that the use of larger heat sinks can increase the maximum (MAX) and average (AVE) temperature of the battery. The minimum T-B occurs at different times for the smaller PCM heat sinks. Also, when using a heatsink with a larger PCM volume, it takes longer for the PCM to fully solidify. A BTP with 5 or 50 battery cells can provide up to 3% or 30% of the THE required for the building.

    Etli, Serkan

    In this study, the seismic behavior of steel-concrete composite buildings designed using ÇYTHYE 2016 and TBDY 2018 was investigated. For this purpose, composite moment resisting frame buildings with concrete filled steel tube columns and composite beams with 5, 10, 15 and 20 stories are modeled. Buildings are designed at high ductility (DCH) levels. During the design of the DCH class structures, the design was carried out for the ZA soil class for 0.79 g PGA in the region selected from the earthquake map given in the regulations. Within the scope of the study, SeismoStruct software was used during the design and performance evaluation of the structures. Incremental dynamic analyzes were used along with nonlinear static pushover analyses. In the static pushover analysis, uniform and triangular load distributions of the lateral load are adopted. In the dynamic analysis, 16 earthquake ground motions were obtained from AFAD earthquake acceleration databases according to the relevant design area and used. The variation of the seismic behavior of CMRFs depending on the variation of the floor number was investigated using nonlinear analysis results. Accordingly, the variation in lateral response, overstrength factors and ductility factors for CMRF structures are presented comparatively. In addition, the section deformation capacities were investigated during the IDR changes during dynamic and static nonlinear analyses. The behavior factor of all CMRFs, especially the CMRFs studied in the case study, demonstrated above-expected performance according to the design assumptions.

    Önen, Cihan; Sandıkçı, Muhammed Bahadır; Dincer, Erhan

    The present study aims to investigate the health behaviors of university office workers related to the working environment, compare them with leisure time satisfaction, and\rsuggest ergonomic solutions. Office workers at Bitlis Eren University and Munzur University, which are situated in the eastern part of Turkey, constituted the population\rof this study. The sample size was 196 based on the formula [n = (N*t2*p*q)/d2*(N-1)+t2*p*q)], which was applied when the number of people in the population was\rknown. The required sample size was determined based on the estimation of a proportion of 0.5 in a finite population of 401, with a 95% confidence interval of ± 0.05 using\rsimple random sampling. The data of Questionnaire and Leisure Satisfaction Scale (LSS) were collected from 178 participants by a face-to-face interview voluntarily. The\rfindings obtained in this study showed that nearly half of the participants did not sufficiently support their wrists and backs and did not adjust their working posture or the\rscreen inclination and brightness. The mean score of leisure time satisfaction was higher for those who worked in places with ideal physical conditions, including heat and\rsound insulation and in places with good psychological conditions without stress and work overload. The leisure time satisfaction score was significantly higher among\rthose who engaged in leisure time activities, such as recreational activities reading books, and physical activity. It was observed that employees in offices with improved\rnoise, heat, workload and stress had better satisfaction levels in leisure time. One cannot separate leisure activities from workplace activities and both should be conducted\rin harmony. As an ergonomic solution, the worktable and tools should be comfortable and designed in a way that does not require the back muscles to be strained.

    Failure-based maintenance planning using bayesian networks: a case study hydraulic turbine

    Yucesan, Melih; Kahraman, Gökhan

    The assessment of existing infrastructures in the energy sector is of great economic importance for the world. The extension of the power generation life of hydroelectric power plants depends on logical decisions regarding the maintenance and renewal of the equipment. For this purpose, a Bayesian network (BN) has been applied to evaluate the failures in the hydraulic turbine to calculate the failure of the turbine. Forty-six nodes have been identified that will affect the operation of the system. Preventive measures have been established for failures with the highest posterior probability. By creating four different cases, failure probabilities and the change of the main fault have been calculated. How much savings could be made in each case is determined with the maintenance. This proposed framework will be guided in determining the maintenance strategies for hydroelectric power plant operators.

    Erguven, Gokhan Onder; Kanat, Gurdal; Erguven, Gozde

    Water is an indispensable resource for living things to survive. In addition to its direct consumption, water is also used in the preparation of foods necessary for eating and drinking. Therefore, it is extremely important that the water used is drinkable, healthy and safe. The aim of this study is to determine the place of network water as drinking water in consumer preferences. In accordance this purpose, an online questionnaire was prepared with 274 participants from different age groups, including students from Yıldız Technical University (YTU) Department of Environmental Engineering and their relatives and neighbours, including different ages and occupational groups. With this questionnaire, the factors affecting their water preferences and water usage profiles were determined. As a result of the survey, 54.1% of the participants use carboy water, 33.8% use pet bottle water, 12.1% use network water. The criteria that consumers pay attention to in their water preferences are taste, smell, color, cleanliness and the amount of mineral substances in the water, respectively. The reasons for preferring the carboy water, which is preferred by the majority, are that they find the carboy water cleaner and safer and that it tastes better. On the other hand, participants who preferred tap water stated that 33.3% of them preferred this water because its clean and reliable properties, 33.3% of it was affordable and 22.2% of it was easily accessible. When the degree of trust in the network water was questioned, 12.2% of the participants said that they found the network water safe, 40.5% did not find it safe and 47.3% said they were not sure. In addition, when the participants ranked carboy water, pet bottle water and network water according to the degree of reliability, the network water was found to be reliable with a large rate of 89.2%. 35.1% of the respondents stated that they would prefer to drink tap water if the Water Administration periodically discloses their water quality reports and indicates that the network water is clean enough.

    Recent studies have paid particular attention to polymer-nanoparticle composite materials considering they have a number of interesting properties, which include optical, thermal, electrical, and others (Reyna-Gonzalez et al., 2009; Yakuphanoglu et al., 2010). In this study, a free radical polymerization process was used to create a copolymer of N-vinylcarbazole (NVC) and benzyl methacrylate (BZMA) at 25–75 mol% each. The procedure was conducted at 70°C with azobisisobutyronitrile (AIBN) acting as the initiator. Nano zinc oxide powders were then added to composites at three different ratios of 5%, 10%, and 15% weight of the copolymer. In order to better understand the structures of the P(NVC-co-BZMA) and its composites, FT-IR, 1H NMR, and UV spectroscopic techniques were also implemented. The optical characteristics of both the pure copolymer and its composites were examined. In the visible region, the composite containing 15% nano ZnO had the highest optical absorbance value. Additionally, the thermal behaviours of the composites and copolymers were analysed.

    Women and patriarchy: Tales of males and ghosts

    Demir, Ayşegül

    Having its roots in faiths such as Judaism and Christianity, the term ‘patriarchy’ refers to a system of authority in which males are regarded as superior to females and wield power over them. While some women have submissively internalized the patriarchal system, others have raised their voices and spoken out against it. Short stories written by women writers are one way to examine this system. However, there is a wide disparity in these authors' attitudes toward women. Some depict brave new women who transform and progress as the narrative goes on, while others feature stereotypical female figures who are submissive. The purpose of this paper is to compare the short stories written by Kate Chopin and Rose Tremain to those by Edith Wharton and Clare Boylan in order to determine whether or how much these authors criticize the patriarchal system. It is argued that Chopin and Tremain are the most critical of patriarchy, whereas Wharton and Boylan represent women within a patriarchal framework. Both Chopin and Tremain provide a comprehensive analysis of human nature, regardless of whether they are discussing men or women, with all of their complexity and inner struggles. Authors such as Wharton and Boylan, on the other hand, depict women in patriarchal societies in their natural state, without offering any solutions or suggestions. In their accounts, societal or sexual injustice is motivated by financial considerations.
