Biomass And Nutritive Value Of Spirulina (Arthrospira Fusiformis) Cultivated In A Cost-Effective Medium

Abstract Introduction Cultivation of spirulina at commercial-scales relies on analytical grade–based media, which are expensive and so are the product. Purpose This study assessed the biomass, proximate composition, and other useful compounds in Spirulina (Arthrospira fusiformis) produced with a cost-effective culture medium (LCMA), and the results were compared with those from a standard Zarrouk medium– grown spirulina. Methods The LCMA medium was formulated by using a commercial NPK10-2...

Group Acceptance Sampling Plans for Resubmitted lots for life tests based on Half Logistic Distribution

Abstract: In this article, a group acceptance sampling plan (GASP) for lot resubmitting is developed to ensure quality of the product lifetime assuming that the product’s lifetime follows the half logistic distribution. The parameters of the GASP are determined by satifying the specified producer’s and consumer’s risks according to the experiment termination time and the number of testers. A comparison between this proposed group sampling and the ordinary group sampling plan is discusse...

Statistical Analysis Of Reports On Domestic Violence In Ghana

ABSTRACT The incidence of the print and electronic media reports on violence and abuse in the domestic setting heightened the interest for this study and has therefore served as a major source of motivation for this research work. The work seeks to investigate the causes of domestic violence vis-à-vis the consequences of such acts. The major findings indicated that domestic violence in Ghana can best be described as violence against women and children. It was also discovered that domestic ...

Estimation Techniques In Generalized Linear Mixed Models With Application To Disease Impact Modelling

ABSTRACT This study applies the theory of Generalised linear Mixed Models (GLMMs) to survey data on disease impact in Ghana. It determines the variables that are responsible for making dependent members of households feel the impact of illness and/or death for three identified types of households. It assesses four models in terms of these variables generated using the Maximum Mean PseudoLikelihood (MMPL) and the Residual Mean Pseudo-Likelihood (RMPL) techniques in SAS. For all four models c...

STATISTICAL ANALYSIS OF FEMALE STUDENTS' ENROLMENT AT THE JUNIOR SECONDARY SCHOOL LEVELS IN NIGERIA

This study is concerned with the female enrolment at the junior secondary school levels in Nigeria. In writing this project, the approach has been to determine the trend in female enrolment at the junior secondary school level by the geo - political zones. This research work is organized into five chapters. The first chapter deals with the introduction of the study. In this chapter, the background information is provided, objective of the study is outlined and the significance of the stu...

SOME NEW ENCRYPTION TECHNIQUES USING FIREWALLS AND RANDOM NUMBER GENERA TORS

ln this work, the researchers consider the concept of Information Security by the application of firewall and encryption techniques. Also, the problem of explicitly exposing infonnation in transit is discussed. We developed several algorithms. Among the algorithms are those of random sequence and non-arithmetic sequence using modified generators for the problem to secure information that may pass through intermediate computers linked in the Internet. Some of these algorithms employ modif...

SOLUTION OF LINEAR ALGEBRAIC EQUATIONS BY CRAMER'S RULE METHOD USING PASCAL PROGRAMMING

The purpose of this work is not to present a collection of routines that might appear in a professional software library; rather, the intention is to introduce a method of solving linear algebraic equations using Pascal Programming. This dissertation solves linear algebraic equations by Cramer's rule method using Pascal Programming. The basis for this method of solution was obtained from the knowledge of numerical method, such a method lies within the discipline of numerical analysis.

MODELING HUMAN DEVELOPMENT INDEX USING DISCRIMINANT ANALYSIS

MODELING HUMAN DEVELOPMENT INDEX USING DISCRIMINANT ANALYSIS By Iwuagwu, Chukwuma E. Nwosu, Moses Obinna Department of Statistics Abia State Polytechnic, Aba Abstract The basic objective of human development is to create an enabling environment for people to live long, healthy and creative lives and it is composite statistic of the life expectancy, education income per capita indicators which are used to rank countries into tiers of human development. The paper determined the critical variab...

DEVELOPMENT OF STATISTICAL PROGRAM FOR DISCRIMINANT ANALYSIS FOR MIXED VARIABLES USING R-CODE

DEVELOPMENT OF STATISTICAL PROGRAM FOR DISCRIMINANT ANALYSIS FOR MIXED VARIABLES USING R-CODE, By Iwuagwu, Chukwuma E. Ibegbulem, Zebulon O. Nwosu, Obinna M. Ekwuribe, Celestine. Department of Statistics, Abia State Polytechnic, Aba, Abia State. Abstract Discriminant analysis is a statistical technique that tried to predict on the bases of one or more independent variables. Whether an individual or other objects can be placed into a particular category of a categorical dependent variables. T...

PERFORMANCE ANALYSIS OF INTERNAL SORTING ALGORITHMS

Internal sorting algorithms constitute a class of util ity programs that are widely used in performing routine computing operations . This thesis examines the t heory and structu res of these algorithms and ill ustrates their basic principles with flowcharts and tabular presentations. PASCAL codes were also developed and implemented for the methods.

A STUDY OF ITERATIVE METHODS IN OPTIMIZATION

ABSTRACT Optimization techniques are called into play everyday in decision making processes involving resource allocation in almost every discipline. However, the development and implementation of algorithm for solving optimization problems are fraught with many difficulties and frustrations. The aim of this thesis has been to examine and identify some of the problems associated with the development and implementation of a class of optimization algorithms and to develop a means of improving ...

COMPARING STUDENTS’ PERFORMANCE IN EXAMINATIONS AT THE ST. JOSEPH SENIOR HIGH SECONDARY/TECHNICAL SCHOOL

ABSTRACT My motivation to embark on this project work was triggered by the academic performance of the students in St. Joseph Senior High Secondary/Technical. The main objectives of this study were to compare the performance of male and female students, use principal components to determine indices for ranking the students in descending order. The Data used in the analysis were sourced from the students’ of St. Joseph Senior High Secondary/Technical third term terminal examination results...
