On Grinbergs' differential geometry and finite fields
(20190327)Emanuels Grinbergs, in his youth, during ten years, from 1933 until 1943, wrote three dissertations on one subject, namely, differential geometry [1, 2, 3]. We think that his work in this direction has been neglected for ... 
Using 2colorings in the theory of uniquely Hamiltonian graphs
(201902)We use the concept of 2coloring in analyzing UH3 graphs and building exact specifications of functions to find new UH3 graphs by Hamiltonian cycle edge extractions 
About Correctness of GraphBased Social Network Analysis
(20170724)Social network analysis widely uses graph techniques. Together with correct applications, in some cases, results are obtained from the graphs using paths longer than one, and due to intransitivity of relationships, several ... 
Fragile Correctness of Social Network Analysis
(20161107)Graph techniques are widely used in social network analysis. However, there are some disputable applications where results are obtained from the graphs using paths longer than one and are not simply applicable to objects ... 
A systematic review of SQLonHadoop by using compact data formats
(20161030)There are huge volumes of raw data generated every day. The question is how to store these data in order to provide faster data access. The research direction in Big Data projects using Hadoop Technology, MapReduce kind ... 
Testing 4critical plane and projective plane multiwheels using Mathematica
(20151027)In this article we explore 4critical graphs using Mathematica. We generate graph patterns according [1, D. Zeps. On building 4critical plane and projective plane multiwheels from odd wheels, arXiv:1202.4862v1]. Using ... 
Root cause analysis of large scale application testing results
(20150824)In this paper we present a new root cause analysis algorithm for discovering the most likely causes of the differences found in testing results of two versions of the same software. The problematic points in test and ... 
ON CYCLE INVARIANT
(20130423)Taking the programming paradigm with the cycle invariant as a base notion there for a ground cycle paradigm, in a more general setting here these things are considered. Epistemological aspects with reference to Rene Descartes ... 
How to draw combinatorial maps?
(20130131)In this article we consider the combinatorial map (rendered by permutations) approach to graphs on surfaces and how between both could be establish some terminological uniformity in favor of combinatorial maps in the way ... 
On building 4critical plane and projective plane multiwheels from odd wheels
(20130131)We build unbounded classes of plane and projective plane multiwheels that are 4critical that are received summing odd wheels as edge sums modulo two. These classes can be considered as ascending from a single common graph ...
