Web Data Mining: A Case Study
With an enormous amount of data stored in databases and data warehouses, it is increasingly important to develop powerful tools for analysis of such data and mining interesting knowledge from it. Data mining is a process of inferring knowledge from such huge data. The main problem related to the retrieval of information from the World Wide Web is the enormous number of unstructured documents and resources, i.e., the difficulty of locating and tracking appropriate sources. In this article, a survey of the research in the area of web mining and suggest web mining categories and techniques. Furthermore, a presentation of a web mining environment generator that allows naive users to generate a web mining environment specific to a given domain by providing a set of specification
Compliance to Environmental Regulations: The Indian Context
Abstract Theoretical exposition of the trade-environment linkage (in the form of Environment Kuznets Curve) has been extensive. While one set of studies show that with the increase in per capita income environmental degradation would decline, the other set of studies has shown that no such trend exists for developing countries. Though environmental laws are in place, firms display a very low level of compliance in developing countries. This article brings out the low level of compliance to environmental regulations in India while trying to identify the main causes
Caste and identity processes among British Sikhs in the Midlands
This article examines the role of caste in the lives and identities of a small sample of young Sikhs in the English Midlands, using social psychological theory. In many academic writings, there is an implicit representation of caste as a negative aspect of South Asian culture and religion, and of caste identification as a means of oppressing vulnerable outgroups. Twenty-three young Sikhs were interviewed, and the qualitative data were analysed using Identity Process Theory. The following themes are discussed: (i) Caste as a Dormant Social Category, (ii) Anchoring the Caste Ingroup to Positive Social Representations, and (iii) Caste as an Inherent or Constructed Aspect of Identity? It is argued that neither caste nor caste-based prejudice appear to be prominent in the lives and identities of our interviewees but that, because caste is an important symbolic aspect of identity which can acquire salient in particular contexts, some Sikhs may wish to maintain this identity though endogamy. What is understood as caste-based prejudice can be better understood in terms of the downward comparison principle in social psychology. The implications for caste legislation are discussed
Branch and Bound Experiments in Convex Nonlinear Integer Programming
The branch and bound principle has long been established as an effective computational tool for solving mixed integer linear programming problems. This paper investigates the computational feasibility of branch and bound methods in solving convex nonlinear integer programming problems. The efficiency of a branch and bound method often depends on the rules used for selecting the branching variables and branching nodes. Among others, the concepts of pseudo-costs and estimations are implemented in selecting these parameters. Since the efficiency of the algorithm also depends on how fast an upper bound on the objective minimum is attained, heuristic rules are developed to locate an integer feasible solution to provide an upper bound. The different criteria for selecting branching variables, branching nodes, and heuristics form a total of 27 branch and bound strategies. These strategies are computationally tested and the empirical results are presented.programming: integer algorithms, branch and bound, programming: integer algorithms, tests, programming: nonlinear, algorithm tests
Generalized Fibonacci Sequences
Abstract The Fibonacci sequence is famous for possessing wonderful and amazing properties. In this paper, we introduce generalized Fibonacci sequences and related identities consisting even and odd terms. Also we present connection formulas for generalized Fibonacci sequences, Jacobsthal sequence and Jacobsthal-Lucas sequence. Mathematics Subject Classification: 11B39, 11B3
Generalized Fibonacci-Like Polynomial and its Determinantal Identities
Abstract It is well known that the Fibonacci polynomials are of great importance in the study of many subjects such as Algebra, geometry, combinatorics and number theory itself. Fibonacci polynomials defined by the recurrence relation 1
