 Dharmaiah Gurram Journal of Global Research in Mathematical Archives , 2013, Abstract: Graph Isomorphism is a one-to-one and on-to mapping between two graphs so that the Properties of each vertex on one graph correspond to the properties of a vertex on the other graph. The graph isomorphism problem is a computational problem of determining whether two finite graphs are isomorphic or not. It is one of the small numbers of a problems belonging to NP neither known to be solvable in polynomial time nor NP complete. In this paper, I proposed an algorithm that determines whether two finite graphs are isomorphic or not. Keywords: Direct Path Set Of Vertex, Set Intersection, Adjacency matrix, Null Set.
 Dharmaiah Gurram Journal of Global Research in Mathematical Archives , 2013, Abstract: In this paper, the idea of assigning lists of varying sizes to vertices of a planar graph will be explored. Thomassen’s 5-list-coloring theorem states that plane graphs are list-colorable when two adjacent vertices on the boundary of the unbounded face are pre-colored, other vertices on the boundary of the unbounded face are assigned lists of size 3, and all other vertices of the graph are assigned lists of size 5. This can be thought of as being 2-extendable. Thomassen’s also defined an analogous property of 3-extendability, and later Definition, which corresponds to having the vertices of a 3-path along the boundary of the unbounded face pre-colored. While every planar graph is 2-extendable, it is not the case that every planar graph is 3-extendable. Keywords: {i, j}-extendibility, {2, 2, 2}-extendable, 3-cycle.

 DHARMAIAH GURRAM AND N.VEDAVATHI Golden Research Thoughts , 2013, DOI: 10.9780/22315063 Abstract: Although graph theory is one of the younger branches of mathematics, it isfundamental to a number of applied fields, including operations research, computerscience, and social network analysis. In this paper we discuss the basic concepts ofgraph theory from the point of view of social network analysis.
 Golden Research Thoughts , 2013, DOI: 10.9780/22315063 Abstract: This paper explores the competing issues of coverage efficiency and power available in wireless sensor networks. Specifically, a shortest distance routing protocol is implemented, and total network system lifetimes are determined using a variety of small percentages of the available system nodes. Using a network simulator developed in Java, wireless sensor nodes are simulated, and power consumption algorithms are included in each node that take into consideration all aspects of power consumption in the operation of the node. Simulating different coverage schemes on the same network system, same initial power sources, and routing protocol, an increase of overall system lifetime of 900% is demonstrated, but also that the network lifetime increase does not increase linearly as the percentage of nodes used in the system is decreased.Wireless sensors, and the arrangement of these small, electronic devices into radio networks, have introduced the capability of remotely monitoring a physical environment for a wide variety of parameters. In effect, there is additionally the ability to interface the physical world, monitoring whatever parameter is of interest, with the internet.

 Gurram Gopal Advances in Management and Applied Economics , 2013, Abstract: Elmhurst College is a small liberal arts college located in Illinois that provides undergraduate and graduate programs in liberal arts as well as professional programs in business, nursing and education. The school faced a serious budget crisis in 1971 and then President Dr. Frick implemented stringent financial measures including the termination of some tenured faculty. After a period of steady growth the school faced another financial crisis in 2003. This paper describes the approach taken by Dr. Cureton, the President, to get all stakeholders involved in charting and executing a course that enabled the College to survive and become stronger. The paper highlights the role played by a President of a small college in building bridges with the faculty and developing equity with this key constituency. The paper concludes with a reflection on the current situation facing the College, with a new President who has to manage a serious set of challenges in the current economic downturn.
 International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.64026 Abstract: Meghadrigedda, a non-perennial drainage system is one of the major water resources of Vishakhapatnam city located in the northern coastal region of Andhra Pradesh, India. It traverses through the hilly terrain of Eastern GhatMobile Belt (EGMB) characterized by khondalitic rock formations. Excessive siltation scenario aggravated due to soil erosion in its catchment is threatening the very existence of Meghadrigedda reservoir. In order to assess the intensity of soil erosion as well as silt deposition in the reservoir, an integrated study has been undertaken which takes into consideration various topographic, morphological, soil, and land use/land cover characteristics of the basin. The study aims at identification and mapping of erosion prone zones with respect to silt deposition using remote sensing and GIS techniques.Alteration in human induced land use practices in its catchment due to rapid growth in population, urbanization and industrialization are found to be of prime reasons for various forms of erosion. The study has noticed that various forms of erosion like sheet, gully and stream erosion are responsible for the siltation at large scale which is causing reduction of its designed storage capacity by 40%. Various sub-watersheds of the basin have been prioritized on the basis of erosion intensity for suggesting various mitigation measures like check-dam construction, afforestation etc. to protect the reservoir from the silting problem.
 Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.75038 Abstract: Recent advancements in internet mapping technology, efficient geospatial data management systems, and availability of different GIS API’s have revolutionized the way in which the geospatial data is being used, shared and represented through distributed systems for business applications. However, development of powerful, highly functional, yet cost- and time-effective enterprise WebGIS business systems requires a very robust and highly scalable architecture. The architecture should have the inherent characteristics of rapid development, a well-defined object library and at the same time it should comply with the existing geospatial interoperability standards defined by Open Geospatial Consortium (OGC). On the other hand, development of extendible distributed business GIS systems requires the presence of tailor-made inbuilt models available as modules which can be extended further by readily implementable user-interface templates supported by object modeling environment which allows for custom design and delivery of the processes and map output. There are various commercial and open source web mapping solutions which offer a great deal of flexibility and functionality. Nevertheless, they restrict the user community with certain limitations, in terms of functionality, cost or complexity. This necessitates, defining a new approach which efficiently caters the user requirements and not limiting them with aforementioned shortcomings. This paper aims to evaluate various architectural alternatives for delivering robust？distributed GIS business solutions and also attempts to give an account of an implementable instance of a WebGIS architecture which can cater the multi-user and multi-industry requirements.
 Advances in Remote Sensing (ARS) , 2016, DOI: 10.4236/ars.2016.54019 Abstract: The study was aimed at appraising the changing land use/land cover scenario of Tummalapalle region in Cuddapah district of Andhra Pradesh using Remote sensing data and GIS technology. The region is considered as it has rich uranium reserves and is experiencing a remarkable expansion in recent times. The land use/land cover change analysis was carried out using IRS P6 LISS-III and LANDSAT-8 OLI multitemporal data pertaining to the years 2006 and 2016. The image classification resulted in five major land use/land cover classes namely built-up, agricultural, forest, wasteland and water bodies. The study noticed that the areas under built-up and agricultural classes are found increased from 0.94 km2 (0.84%) to 2.75 km2 (2.44%) and 61.68 km2 (54.84%) to 63.91 km2 (56.82%), respectively during 2006-2016. Area under forest, wasteland and water bodies are found decreased considerably from 3.09 km2 (2.75%) to 0.86 km2 (0.76%), 43.71 km2 (38.56%) to 42.60 km2 (37.88%) and 3.05 km2 (2.71%) to 2.35 km2 (2.09%), respectively. The study recommends development of industrial based economy by optimally utilizing the existing land resource (scrub and wasteland classes) and simultaneously extending the agricultural practices to other possible areas to make them more productive.
