Evaluation process is an integral part of academic system in order to monitor the performance of students from many perspectives. Since, recent past lots of methodological changes has been taken places in evaluation process from traditional one. Many experts from concerned domain claims the superiority of one method over other but still dilemma continue with reference to optimum or appropriate method. In this connection even very recently being used to a maximum extent in Indian context too is the “Grade Method”. However, even “Grade Method” is also not completely free from certain controversies. That is, though grades were initially meant to serve various pedagogical purposes, grading systems remain controversial and hotly debated when those doesn’t give recompensing results. Some argued that grades are psychologically harmful. Thus, given certain limitations of existing methods in some respect, the current study has been undertaken in order to address few issues associated with mi...

In research paper, it was studied about degree of vertices of a semitotal blocks in fuzzy graphs. In process we obtain some interesting results regarding the degree of the vertices in semitotal blocks in fuzzy graphs. We observed that when ‘B’ is a block of a given fuzzy graph G:(V, �, µ), then degree of the vertex B in semi total block fuzzy graph T STB F(G) is equal to the sum of the membership grade of the vertices in that block and the number of edges in T STB F(G) related to block B is │V(B) │ with membership grade minimum of �(u), �(B). Also, we obtained that when G:(V ,�,µ) fuzzy graph and v be a fuzzy vertex with degree d FG (v) in G:(V ,�,µ), then the degree of ‘v’ in semitotal block fuzzy graph T STBF (G), d STFG (v) equal to the sum of the degree of the vertex in fuzzy graph and the product of |{B/Bis a block in fuzzy graph containing v} | with minimum of the set { �(v), �(B)}. Finally, it is proved that the ring sum of given fuzzy graph and vertex block fuzzy graph is eq...

This article explains an influence of heat generation on MHD natural flow convective a vertical permeable surface with radiation. By using perturbation technique the equations of governing are converted to a system of non-linear O.D.E’S and are explained mathematically. Numerous physical limitations like M, F, Pr and some other parameters are studied through diagrams and tabular values. As conclusion of this investigation, decreasing in velocity profile as numerical standards increased in major cases except few effects like absorption radiation parameter R, Schmidt number Sc over velocity flow. The same effects are investigated for temperature profile as well as concentration profile

B. Satyanarayana, S. Prasad and D. Nagaraju [“Prime graph of a king” (communicated)] introduced the concept prime graph of R (denoted by PG), where R is a given associative ring. Related to a given non-null ring R, a ring called satya-ring (denoted by S(R)) was considered. The aim of this study is to construct the prime graph of S(ℤ 2 ) and S(ℤ 3 ) and find out several important properties. Finally it is observed and proved that there exists four distinct maximal complete subgraphs in S(ℤ 3 ) each of which is isomorphic to the complete graph K 0 on nine vertices.

Abstract The influence of oxygen (O) content on the microstructure and mechanical properties of cold rolled Ti-32.5Nb-6.8Zr-2.7Sn-xO (TNZS-xO; x = 0, 0.3, 0.6; mass%) alloys after aging at temperature range from 350 to 600 °C for 24 h was investigated. Results showed that the cold rolled TNZS-xO alloys possess single β phase. During the aging process, O could not only effectively suppress the precipitation of ω phase but also retard the formation and decomposition of α phase. In addition, the corresponding temperatures of the maximal volume fraction of α phase precipitation and the (α+β)/β transus temperatures of the TNZS-xO alloys were all increased with the increasing of O content. For mechanical properties, it was found that the strength and Young's modulus of the TNZS-xO alloys increased owing to the ω phase and/or α phase precipitation and decreased owing to the α phase decomposition. However, the elongation showed the opposite change tendency with the above mentioned strength. The mechanical properties of TNZS-xO alloys can be controlled over a wide range by subjecting to aging treatment and/or changing their O content. When aged at or below 450 °C, the TNZS-xO alloys exhibit great potential to become a series of new candidates for biomedical applications since they possess high strength (870–1460 MPa), low Young's modulus (45.1–75.6 GPa), high strength-to-modulus ratio (0.018–0.02) and appropriate elongation (7.2%–14.9%), which are superior to those of Ti-6Al–4 V alloy and suitable for the use as bio-implant materials.

Many real life situations for which there are no optimization algorithms which can solve polynomial time problems in the worst case. So researchers are trying for new approximation algorithms for such kinds of situations. Approximation algorithms give the solution which is close to the optimal solution of a particular situation. Traveling Salesman Problem (TSP) is a typical NP complete problem which lacks polynomial time algorithm. In this paper it is proposed an edge removal algorithm, which will give the nearly optimal solution within a limited time.

—In real world scenarios, transitive closures play a vital role in computer networks RDBMS and Graph theory. An efficient algorithm to find transitive closure is in need. Following paper presents new algorithms to find out Transitive Closure of a Relation Matrix and compares the performance with Warshall algorithm. Sections 3 and 4 explain primes and GHK algorithm respectively. Primes algorithm uses prime numbers to find out transitive closures of a relation, and GHK algorithm uses bit sets to find out the transitive closures of a relation efficiently. Section 4 presents experimental results of Primes and GHK against Warshall " s algorithm.

In research paper, it was studied about degree of vertices of a semitotal blocks in fuzzy graphs. In process we obtain some interesting results regarding the degree of the vertices in semitotal blocks in fuzzy graphs. We observed that when 'B' is a block of a given fuzzy graph G:(V, σ, µ), then degree of the vertex B in semi total block fuzzy graph T STB F(G) is equal to the sum of the membership grade of the vertices in that block and the number of edges in T STB F(G) related to block B is V(B) with membership grade minimum of σ(u), σ(B). Also, we obtained that when G:(V ,σ,µ) fuzzy graph and v be a fuzzy vertex with degree d FG (v) in G:(V ,σ,µ), then the degree of 'v' in semitotal block fuzzy graph T STBF (G), d STFG (v) equal to the sum of the degree of the vertex in fuzzy graph and the product of |{B/Bis a block in fuzzy graph containing v}| with minimum of the set { σ(v), σ(B)}. Finally, it is proved that the ring sum of given fuzzy graph and vertex block fuzzy graph is equals to the semitotal block fuzzy graph of given fuzzy graph.
