Currently, many solutions exist for measuring CF, but the application methods are complex and costs are high. We propose a solution in which we utilise off-the-shelf components in an affordable package, which is able to measure CF. The prototype that was built demonstrates the ability of discriminating between stressed and non-stressed plants, and shows potential as a low-cost fluorometer. As the focus is less on accuracy and more on relative results and cost, this opens up the possibility of using multiple sensors in a wireless sensor network (WSN). In this paper, we explain the underlying methodology and its relation to known methods, and verify the system in its usefulness as a low-cost CF sensor.","PeriodicalId":336703,"journal":{"name":"2016 VI Brazilian Symposium on Computing Systems Engineering (SBESC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132933578","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 this paper, we describe the preliminary results of a work that presents a method to integrate formal verification techniques adopting ESC/Java2 and JCute tools with unit testing by TestNG framework to verify Java programs. This method aims to extract the safety properties generated by ESC/Java2 to automatically generate test cases using the rich set of assertions provided by the TestNG framework and JCute to validate those test cases. It is worth noting that is widely recognized that there is a growing need for automated testing techniques aimed at mobile applications, in platforms, such as: Android or Java Platform, Micro Edition (Java ME). Additionally, a critical challenge is the systematic generation of test cases. We show preliminary results of our proposed method over publicly available benchmarks, and compare the results to recognized tools, e.g., CBMC and JavaPathFinder. Experimental results show that our proposed method detects 86.04% of correct results (i.e., if a property satisfy its specification or is violated), while CBMC has found 79.06%, and JPF has found 93,02%.","PeriodicalId":336703,"journal":{"name":"2016 VI Brazilian Symposium on Computing Systems Engineering (SBESC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126477881","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}
