Reconnaissance after the severe earthquakes pointed out that seismic performance of non-structural members and elements could be as significant as the structural members in lateral force-resisting systems. As such, it is important for design engineers to recognize the seismic demand on the mechanical systems that support the critical non-structural components (e.g., sprinklers, electrical and mechanical equipment, etc.) in terms of the safety during and after an earthquake as well as functionality and retrofitting cost after an earthquake. The primary goal of this study is to systematically investigate the seismic demands on the mechanical support systems of a typical mid-rise steel structure. For this purpose, non-linear time history analyses are carried out using a suite of ground motion acceleration records to evaluate the seismic demands on both seismic force-resisting system and the support system by means of inter-story drift angle and horizontal accelerations, respectively. Results obtained from the analyses are discussed considering the requirements stipulated in the current national and international buildings and recommendations are made.","PeriodicalId":117452,"journal":{"name":"Orclever Proceedings of Research and Development","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121611082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toparli","doi":"10.56038/oprd.v1i1.157","DOIUrl":"https://doi.org/10.56038/oprd.v1i1.157","url":null,"abstract":"Today, there are specially developed fasteners for situations where the need for security and permanent connection is at the forefront. The first thing that comes to mind is the \"shear bolt\", a fastener that only allows tightening. In this fastener, there is a specially thinned area under the head with machining, and thus, when the bolt reaches a certain torque value, a break occurs in the head part. Thus, a permanent connection is obtained since the hexagon part used only during tightening is eliminated. One of the disadvantages that arise with the use of shear bolts is that there is a significant amount of material used only during tightening and it increases the cost. In addition, uncoated area on the fracture surface makes possible corrosion problems and an extra cost from machining is another disadvantage. The disposal of the broken head part during mass production also appears as an extra cost. In order to prevent these problems, the Norm One Way (NOW®) product, whose patent belongs to Norm Cıvata, has been developed. Thanks to the special head and socket geometry, tightening is done only in one direction and disassembly is not possible. In this study, the effect of increasing the socket depth on the head strength of the bolt was investigated using experimental, analytical and finite element methods. As a result, NOW® product was obtained which is safer, has a head form that will eliminate the possibility of stripping during assembly and at the same time provide maximum weight reduction.","PeriodicalId":117452,"journal":{"name":"Orclever Proceedings of Research and Development","volume":"454 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116766776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most preferred feminine hygiene products is sanitary pads. Sanitary pad is a thin pad made of absorbent material that comprises numerous layers of quilted cotton fabric or other super absorbent polymers and plastics. Soft touch, dry feel, odourless, leakproof and antibacterial properties are the expectations from a sanitary pad. Considering these expectations, in order to replace with the disposable (single use) ones we have developed a reusable sanitary pad with wings that all individual layers of fabrics are designed and produced. Drying time, pilling resistance, thermal and water vapour resistance, air permeability, dimensional stability, hydrostatic pressure, tensile strength, tear strength, phenolic yellowing, pH level, bursting strength, thickness, mass per unit area tests are carried out. \u0000According to market outlook reports the total sales of reusable sanitary pads represent ~5%- 10% of the global health and personal care market. Disposable (single use) sanitary pads end up with landfilling and disposal by incineration and cause environmental pollution. From the perspective of woman health, equality of opportunity, sustainability and environmental health concerns it is concluded that reusable pads are a sustainable alternative for the disposable (single use) ones.","PeriodicalId":117452,"journal":{"name":"Orclever Proceedings of Research and Development","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117209762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insufficient accuracy of the estimations leads to loss of income and increases secondary costs such as transportation and labor costs. In the current situation, sales forecasts are based on the sales personnel's delivery route, knowledge, experience, and relationships. Since the knowledge and experience of the personnel are not brought into the institutional memory, this information is lost with the personnel change, and the new person needs to develop their own experiences about the route. Currently, the sales forecasting accuracy rate is calculated as 70%. It has been determined that a daily loss of 15% on a product basis and a total of 5% daily occurs. In the study carried out within the scope of this research, advanced analytical and machine learning methods that can capture the dynamics of the FMCG industry and analyze the extensive data formed effectively are studied to increase the accuracy and consistency of sales forecasts. Within the scope of the research, machine learning models to be used for sales forecasts were developed using artificial neural networks methods. We evaluated the models' performance according to the recall, precision, and accuracy metrics based on the route, point of sale, and product. It was determined that the artificial neural networks performs well for sales forecasting. Using the artificial neural networks in the experimental study, we achieved an average of 5% revenue increase for the three route groups selected as pilots. The sales forecast accuracy rate increased from 78% to 82%.","PeriodicalId":117452,"journal":{"name":"Orclever Proceedings of Research and Development","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125153874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to make the OEE calculation properly, one needs to digitize the accurate data coming from the production line on the shopfloor, which is a challenge itself. The solution we present provides the accurate collection of production line status and OEE data required for monitoring and decision making. The problems found in existing solutions are overcome with advanced analytical methods such as video image processing and deep learning / machine learning. There are many solutions in the literature using traditional image processing approaches [Dalal, 2005] or machine learning methods [Felzenszwalb, 2010] to solve the object detection problem in the video. In recent years, deep learning methods have also yielded successful results in object detection [Girshick, 2014]. The innovative aspect of the solution we offer is that it is a system that learns patterns that may be different for each production line, and automatically predicts the production line status.","PeriodicalId":117452,"journal":{"name":"Orclever Proceedings of Research and Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114727176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the reactive dyeing process itself and various finishing processes applied after dyeing affects the physical, mechanical, handle, comfort and functional properties of the fabrics. Therefore, the main aim of this study was to determine the dyeing and finishing processes on the quality-performance characteristics of the cotton knitted fabrics. For this aim, physical (weight, wale/course density), mechanical (bursting strength, pilling, abrasion resistance), handle (bending rigidity), comfort (thermal comfort, air permeability, water vapor permeability) and functional (Ultraviolet protective functionality and flame retardancy of the fabrics) properties of fabrics were tested before and after dyeing and finishing processes. Fabric weight and bursting strength values increases after dyeing and finishing processes due to the shrinkage of the fabrics during wet processing. On the other hand, the pilling and abrasion resistance values of fabrics are not significantly affected by dyeing and finishing processes. Another important result obtained is that the bending length and bending stiffness of the fabrics decrease after dyeing/finishing processes. The thickness values of the fabrics decrease after dyeing-finishing processes and therefore the thermal resistance decreases. It was observed that the air permeability of the fabrics significantly decreased after dyeing-finishing processes. However, the water vapor permeability of the fabrics was decreased very slightly after dyeing and finishing processes. UPF ratings were increased after dyeing and finishing processes. \u0000Keywords: Cotton, dyeing, color, functionality, permeability","PeriodicalId":117452,"journal":{"name":"Orclever Proceedings of Research and Development","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125968744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
