The research is divided into two parts, the first one is the RCS test of the quadcopter in an indoor environment compared to an outdoor environment. The second part is the RCS test of the quadcopter in an indoor environment while the quadcopter is flying in the air compared to the quadcopter mounted on a stand as in the first test. The results showed that the RCS of the quadcopter in both environments responded to the structure of the quadcopter in the same way, but the RCS of quadcopter in indoor environment has higher RCS anomality oscillation compared to the RCS of quadcopter in outdoor environment. In addition, the quadcopter that is flying in the air compared to the quadcopter mounted on a stand has found that the majority of the quadcopter’ RCS is similar.","PeriodicalId":441430,"journal":{"name":"2022 8th International Conference on Engineering, Applied Sciences, and Technology (ICEAST)","volume":"141 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134162619","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}

It is precisely described based on the mathematical concept of relation. The abstract concept is presented by the tabular format, commonly known as the SQL tables. Due to the simplicity of the tabular format and the simple, high productivity SQL language, software developers without or with minimum theoretical backgrounds can use RDBMSs for application development. There are also DBMSs which are based on other database models which do not use the SQL language and are collectively called NoSQL databases. These systems' advocates claim that the Relational Database Model and RDBMSs require ACID transactions. This paper clarifies the related terms and concepts of the Relational Database Model. The more recent concept of relation variable is explained and related to SQL tables. ACID properties of transactions are also presented to confirm that they are not directly related to a particular database model. Thus, it is a misconception that the Relational Database Model requires ACID properties.","PeriodicalId":441430,"journal":{"name":"2022 8th International Conference on Engineering, Applied Sciences, and Technology (ICEAST)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114206854","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 received signal strength indicator (RSSI) and path loss characteristics are addressed by using the free space path loss (FSPL) model, air-to-air two- ray (A2AT-R) model, and the modified Log-distance path loss model. The measurement results indicated that the limit of power constraint of WiFi modules was a level at 10 m Rx-UAV altitude, and the received sensitivity was limited at -95 dBm. It is shown that the impact of ground reflection path loss was characterized at 1–3 m Rx-Uavaltitudes which are accordingly related to the A2AT-R model and the relative resulting with the modified Log- distance model above 4 m Rx-UAV altitudes.","PeriodicalId":441430,"journal":{"name":"2022 8th International Conference on Engineering, Applied Sciences, and Technology (ICEAST)","volume":"408 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126687711","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}
