Abstract: Science and technology have been improving rapidly, and it changed everything. Today, very seldom we can find a super computer as in the late 1970s. The computing, processing of data rely on a server or multiple servers depending on the need of a firm or a company. Everything became smaller, a server is just a little bigger than a personal computer (PC), and we have many different programming languages for developing software applications. The subject, concept of Automata and Computing Theories was introduced in 1979, and in those early years, Automata, Computing Theory, and Language Theory were still listed as an area of active research, based heavily in Mathematics and largely a graduate course [1].

Keywords: Automata, Computing theories, Formal language, Science, Technology, Computing machines, Turing machines, Mathematics.

Abstract: The convergence of GIS and internet has changed the map making a cost-effective way to share or provide public access to geo-informatics worldwide. Internet has changed shaken the traditional approach and has brought paradigm shift in the process of thinking and societal interactions based on technological development. For preparation of local level plans and functioning, it is becoming increasingly essential to have decentralized database and Web-based GIS functions for local or decentralized planning. The datasets contain all geospatial database created for integrated rural development of Bemetara district of Chhattisgarh state. These datasets contain two types of data spatial and attribute data of all concerned lined departments. Geospatial layers used as dataset for creation of web based Decision Support System. Web materials used in generating Web Based Decision......

Abstract: Background:Road transportation is central to everyday life, but is often hampered by traffic congestion in developing countries. This paper proposes a routing system that promises to reduce traffic congestion on the road by constantly suggesting the optimal alternate routes to motorists while considering the condition of the road segments. Materials and Methods:The optimal alternate route is computed by the system based on the digitized map and the geographic information system of the city that are stored in the database. Secondary data for the research was obtained from Lagos state ministry of transportation. Results:The experimental results show that out of every 10 samples, the proposed approach differs only in two cases. On inspecting each case, it was observed that the approach reported in this work differs from the existing approach whenever there is a bad road segment.......
