On\u0000holidays, a lot of rush can be seen in shopping malls and it becomes a very tedious task to get the billing done. In\u0000cosmopolitan cities, to shop at supermarkets and shopping markets an everyday task. Everyone of us has\u0000encountered long queues for the payment of the bill at shopping centers during holidays and weekends, the rush\u0000increase seven more at the time of festive seasons because of the discounts and product offers. Customers pick the\u0000products they want to buy and put them into their shopping carts. After customers have picked the products, they\u0000need to get the billing done. For the payment of the bill, they have to move to billing counter. At the billing counter\u0000the cashier, scans the products using a barcode scanner and then produces the bill. This is a manually operated\u0000process and hence, time consuming. Therefore, it leads to the long queues at billing counters. This paper proposes a\u0000way to develop a brilliant shopping cart system that will monitor the purchased products and help produce the bill\u0000in a less time-consuming way. This paper looks forward to solving the problem of rush at billing counter using a\u0000barcode scanner and RF transceiver that sends and receives the data.","PeriodicalId":23534,"journal":{"name":"Volume 5, Issue 4","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90166849","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}

A random selection of 30 educators\u0000and 30 students who participated in the contests were also interviewed to find out their views about the competition\u0000and its impact on their computational thinking and creativity skills. Furthermore, 85 projects made up of codes from\u0000the Scratch program and submitted during the final round of the contest during the years 2016 to 2018 were\u0000processed using an online analytical tool known as Dr Scratch. To identify the progress made by the students, the\u0000different computational thinking concepts were analysed more deeply. The study revealed that over three years of\u0000the Codecraft competition, there was a significant improvement regarding the use of programming concepts, logic,\u0000and computational practices.

But\u0000depending on cost and availability, it is therefore necessary to replace the steel with some other suitable materials. There's a\u0000situation where production isn't found to be sufficient to meet steel demand. Hence, having an alternative that is worth\u0000compared to steel is essential. Bamboo is one of the alternate materials used as a steel replacement in the construction of\u0000small structures and low-cost housing, particularly in countries like India. Bamboo is found in abundance, they are durable,\u0000and they can satisfy the demand as a reinforcing material and become a perfect substitute for steels. Compared with other\u0000materials including steel, the tensile resistance property which is the main requirement of reinforcing material is considered\u0000appreciable for bamboo. This property is given out from its origin through the bamboo structure. When in natural habitat,\u0000the hollow tubular structure has a high resistance to wind forces. Working on bamboo's weak points and bringing up bamboo\u0000innovation as a replacement for structural steel would be a great alternative. The goal of this present work to carry out a\u0000literature survey to determine the feasibility of bamboo reinforcement for a concrete structure. The mechanical properties\u0000and behaviour of steel-reinforced concrete have been extensively studied and well documented, there is no detailed data\u0000explaining reinforced concrete from bamboo exists. Therefore, the aim of this study is to provide a preliminary contribution\u0000toward the collection of literature to know the state of art characteristics such as mechanical properties and behaviours of\u0000bamboo reinforced concrete, with a view to solving specific problems of low-cost housing","PeriodicalId":23534,"journal":{"name":"Volume 5, Issue 4","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79267785","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}
