MIT App Inventor is a visual block programming environment created for mobile application development by novice programmers, and is widely used around the world for learning programming. This paper describes the literature review conducted by applying search and selection criteria, using specialized search engines, followed by the analysis of the 35 selected studies (experiments and experiences) on the teaching-learning process of programming conducted by teachers from various countries, using App Inventor. The findings indicate a high acceptance in the academic community of App Inventor as an effective tool for motivation and performance of students who are initiated in programming, without distinction in the educational level.

“…Corroded pipes lead to small cracks that eventually form leaks. 4. In the transportation of fluids for longer distances through a pipeline, leaks can also occur due to harsh environmental conditions.…”
In process industries, leakage in pipelines is common and an environmental, health and economic issue to be addressed without fail. To detect the presence of leaks in pipelines, there are several conventional leak detection techniques that are available. From the literature, conventional leak detection techniques can be mainly classified into: hardware-based, visual and software-based methods. Researchers have focused more on software-based methods due to simple and reliable operation. Under software-based methods, using machine learning algorithms that is a data driven approach for leak detection and localization is becoming popular because of learning capabilities. Therefore, in this review, several recent conventional leak detection methods and artificial neural networks/machine learning based leak detection methods are described. It is an attempt made to identify leak detection techniques along with the common methodology followed for building a leak detection system using artificial neural networks/machine learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
