The technology of layer-by-layer cooling of a casting is considered, which ensures the formation of a casting with a uniform fine-grained metal structure. This effect is achieved due to the slow filling of the cooled mold cavity with cooling liquid due to the difference in the flow rate of the liquid at the inlet and outlet. At each moment of time, the cooling of the metal is carried out by a thin layer of the casting, which ensures the uniformity and fine-grained structure of the casting material, the absence of shrinkage and internal stresses.","PeriodicalId":228424,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 9","volume":"8 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124463484","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 universe is actually a form of information that has been encoded. The universe speaks to us in a universal language. The tragedy is that the mysteries are difficult to decode in order to understand the laws that govern the universe's functioning. Some parameters in the universe are explicit, and they can decode the entire universe. Space and time, for example, might be seen as necessary conditions of the universe, but mass and energy might be seen as sufficient circumstances. All we have to do now is figure out how to connect all four parameters. This chapter will go through how we can change any of the four conditions into the rest of the conditions. The speed is a parameter that relates space with time. The mass-energy equivalence condition of Einstein can aid in the transformation. I'll illustrate how a space-time-mass-energy matrix can be used to represent the transformation mathematically.","PeriodicalId":228424,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 9","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130196461","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}

Kotak","doi":"10.9734/bpi/castr/v9/10386d","DOIUrl":"https://doi.org/10.9734/bpi/castr/v9/10386d","url":null,"abstract":"The term \"smart\" now encompasses the entire world, such as \"smart city,\" \"smart phone,\" \"smart watch,\" and so on. The study effort for this project looks at the possibilities of full home/office control, which is the goal of a real-time monitoring and control system in the near future. This project presents the analysis and implementation of home automation technology using a Global System for Mobile Communication (GSM) modem to control home/office appliances such as lights, air conditioners, fans, water tanks, and security systems via the World Wide Web and Short Message Service (SMS) text messages. Switching on/off of air conditioners based on the number of people in the room is an additional element of the system that adds to its attractiveness. The proposed research focuses on GSM protocol functionality, which allows the user to control the target system while away from home. Home appliances, such as lights and fans, may be controlled remotely via a website. Theft detection message can be given by SMS if net signal is not available. The server will be connected to relay hardware circuits that will operate the home/office appliances. The communication with the server enables the user to select the appropriate device. The smart GSM-based real-time system was developed using the concept of serial communication and AT-commands. Homeowners will be able to receive feedback on the status of any household appliances they manage remotely, whether they are turned on or off. PIC 16F887A microcontroller with the integration of GSM plays an important role with the desired baud rate of 9600 bps. The projected prototype of a GSM-based home automation system has been developed and tested with up to four loads and has shown to be functional. The proposed work provides an efficient, secure, and cost effective easily operated solution for real time monitoring and control in smart homes/offices with the touch of a button on a smart phone or a laptop.","PeriodicalId":228424,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 9","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751193","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}
