The search for thermal comfort has encouraged the use of technologies such as the TES tank (Tank Energy System). This article presents the validation of the results obtained in the CFD simulation of a TES tank, through an evaluation of the model at 1/25 scale, to corroborate the thermal resistance of the tank whit thermal conductivity of 1.63 W/m. °K and expanded polystyrene with thermal conductivity of 0.036 W/m°K for both the walls and the lid. The circular TES tank designed guarantees, in addition to adequate thermal resistance, impermeability and durability so that it can function correctly during temperature measurements. In the model, the thermal resistance of the tank was corroborated, by obtaining an increase in the temperature of the temperature of the water in 8 hours of 7 °C (12.6 °F). That is, from 5.9 °C (42.62 °F) to 12.9 °C (55.22 °F), which does not exceed 15 °C (59 °F), the recommended value for its viability.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82049296","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 ancient feudal society, the same group of people formed a pyramid structure. Taking the Qing Empire as an example, the emperor's robe is yellow with a dragon emblem embroidered on it, symbolizing the emperor's majesty, while the official robes are divided into bird patterns and animal patterns, forming a strict hierarchy. In addition to the level identification between the same groups, the power information and other information of different groups can also be clearly distinguished from each other. For example, the Japanese family crest shows the family information to which the individual belongs, while the European family crest is more of a multi-level presentation, which may include family, class, status and other information. In addition, both of them have a long history and culture and a well-structured and systematic emblem pattern. When later generations studied the totem emblem patterns in other regions, they invariably used the two as a reference for comparison. What are these coats of arms and coats of arms used as a basis for judging status and class? This is the goal of this study, and it is hoped that the final findings will serve as a reference for other researchers.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89442149","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}

The more patients who need to be treated; the more valuable medical resources become. With the increase of human population and the used of medical resources, how to effectively arrange medical resources has become the major problem faced by medical centers. However, different medical departments have different kinds of medical resources, and customizing the scheduling system for each department is not an effective approach. To solve this problem, we surveyed different medical departments in a (Medical Center in Southern Taiwan, summarize the needed, implemented a modularization Medical Scheduling System (MSS), for a Medical Center in Southern Taiwan, and resolve the complex appointment scheduling problem in a multi-clinic. The MSS improves work assignment effective and sensible utilization in medical device. Furthermore, it can be used for epidemic prevention and the control of Covid-19 pandemic.

First, Pasternak two parameter foundation model is introduced to establish the elastic foundation beam model of tunnel landslide interaction, which solves the soil discontinuity of Winkler foundation in the previous theory, and the transfer matrix method is used to derive the transfer matrix formula. Then, Matrix Laboratory (MATLAB) is used to compile the corresponding calculation program to analyze the distribution characteristics of internal force and deformation of the tunnel. Finally, the influence of relevant parameters such as the elastic coefficient of foundation inside and outside the landslide deformation area, the magnitude and distribution of landslide thrust, and the foundation shear stiffness inside and outside the landslide area are analyzed.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91063822","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}

Nowadays, there are two main installing techniques, which are state of the art: compression or crimping and bolted mechanical connections. The bolted mechanical connectors are installed by hand with the use of a mechanical wrench. The customer demand of using impact wrenches (IW) is growing because of the higher installation comfort. However, these techniques differ from each other significantly as the quality of the connection depends on the screwing force applied by the bolt to the conductor. Therefore, a new approach by using a cordless screwdriver was investigated. This contribution addresses the topic of the quality of the electrical connection as a function of the assembly method used on mechanical connectors. In particular, the focus is on assembly by hand with the support of mechanical wrenches and assembly with impact wrenches. Furthermore, a method is presented that combines the advantages of both methods, whereby the disadvantages are eliminated. This involves the use of an adapter, the torque amplifier, which is part of the installation philosophy of Nexans Power Accessories. First, the fundamentals as well as the current state of the art of connection technology are presented. This is followed by a description of the assembly methods and materials used in this work and a comparison of the electrical, mechanical and thermal properties according to IEC 61238 of the connection using the different assembly techniques. Finally, the advantages and disadvantages are compared and presented and discussed using tabular and graphical representations.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85525982","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}
