This paper puts light on the technology of Holographic Projections. It examines the relevance of this technology in today's era and describes the process of production of holograms. The significance of holography is further elaborated upon through its various applications and possible future uses. An introduction to the Microsoft HoloLens provides an exciting account of an implementation of this wave of technology through it, serving as the first untethered holographic computer thereby doing what technology does best -making life easy.
There has always been a struggle for programmers to identify the errors while executing a program-be it syntactical or logical error. This struggle has led to a research in identification of syntactical and logical errors. This paper makes an attempt to survey those research works which can be used to identify errors as well as proposes a new model based on machine learning and data mining which can detect logical and syntactical errors by correcting them or providing suggestions. The proposed work is based on use of hashtags to identify each correct program uniquely and this in turn can be compared with the logically incorrect program in order to identify errors.
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.
