Abstract "Times New Roman""> Cryptography is the practice and study of techniques for secure communication and has become so powerful that messages scrambled with it are virtually undecipherable, like many powerful technologies, this is a double -edge sword. In Cryptography,encryption can keep emails, financials transaction and electronic commerce over the internet, secure and private. In this paper, we tried to put the topic of cryptography into context, discussed the main objectiv...
ABSTRACT Any problem has a set of valid results. It is said to form the solution space. In anoptimization problem, the main aim or goal is to find results that maximize orminimize a set of criteria. If we look at the solution space as ann-dimensional space then essentially we are searching for a global minima ormaxima in the solution space. The Genetic Algorithm is a type of algorithm forsearching the solution space and finding maxima or minima, though notnecessarily the global maxima or mini...
Abstract F-Sulfo Fatty Methyl Esters sulfonates (F- MES) are new anionic surfactants obtained via sulfoxidation of fatty acid methyl esters (FAME) with SO2, O2, and ultraviolet light of appropriate wavelength. The designation of Φ refers to the random positioning of SO3 in the alkyl chain. In this work we summarize the most relevant results of our research started fifteen years ago, on the synthesis, separation, analysis and performance of F-sulfo fatty methyl ester sulfonates know...

Abstract Based on presentation of the principles of nonorthogonal problem, we discuss the difference of some approaches. A simple procedure to include the R-squared and Root Mean Square Error (R.M.S.E) is proposed and tested. The results showed that the Partial Least Square Regression provides better predictions due to a small R.M.S.E value. Keyword. Nonorthogonal, Mean Square, Partial Least Square, R Square. Table of Content 1.0 Introduction 2.0 The Ordinary Least Square Model 2.3 Ridge Re...
AbSTRACT This research work is based on the construction of control chart for quality characteristics of Coke liquid (Sodium content, Sugar content and Volume) which may be used for control of future products of the Coca-Cola Company. Secondary data collected from Coca- Cola Company, Idokpa, Benin City Plant was analysed using Control Chart for process variability and process average. Through the application of statistical Quality Control technique, the product quality was examined and proces...
ABSTRACT In this project, Partial Least Square Regression was compared with Ordinary Least Square Regression (OLSR) to handle the problem of multicollinarity and small sample size on all Nigeria Insurance Company’s expenditure data. The prediction methods have been compared for efficiency through Root Mean Square Error (RMSE) and Mean Square Error (MSE). It is found that in this project Partial Least Square Regression (PLSR) provides better prediction as compared to the Ordinary Least Squa...
Outliers are every day problems encountered in all spheres of life. This work addresses the different methods of labelling outliers and as well highlights the applications of outliers in real life processes
ABSTRACT Technology has proved beyond all reasonable doubt that compt4er technology application could remove the strenuow burden of paper work which have been affecting that Bursary award system of udi local government. The accumulated files and others documents makes collection and disbursement of finance tedious and cumbersome when processed manually, after much observation on the activities of the students bursary award system. With the introduction of computers, an automated form of proc...
INTRODUCTION Nowadays, it seems like almost every one own a car and in fact, we can say that each house have at least one car. But the more is approximately three cars per house. This figure shows that car is very important to people’s life as it completed the cycle of living. Without a car, it is almost impossible to move from one place to another especially for those who are always mobilise in their jobs. Car simplified our life and it makes time to be more valuable as we can save much ti...

color:windowtext">ABSTRACT The place of adequate nutrition in the live of the young especially in the recently weaned cannot be overemphasized. The abrupt change in diet, leading to possible immune system weakness and disease conditions, is a focal point in the care of the young. This project examined serum globulin and bilirubin levels in weanling rats whose feed was supplemented with Emilia sonchifolia leaf extract. The extract was also screened for phytochemical contents and the eff...
ABSTRACT The strategy of utilizing mechanochemical synthesis to obtain metal-organic frameworks with high surface area and nanodisperse particles has been espoused. Transition metal ions have been shown to form complexes with organic moieties such as benzyl-N,N-dimethyldithiocarbamate. It has been established that iron in its oxidised state (Fe3+) is cidal to microorganisms and dialkyldithiocarbamates have an established antifungal activity, the complex of Fe3+ and benzyl-N,N-dimethyldithioc...
ABSTRACT A Linear Variable Differential Transformer (LVDT) was constructed having a primary winding of 245 turns and two secondary windings of 100 turns each. The devicewas calibrated with a graduated cylindrical rod. The graduated rod wheninserted between the hollow tube which has the windings gave output voltages of±0.046V, ±0.51V, ±0.088V, ±0.155V, ±0.271V and ±0.395V for displacements of±0.00cm, ±2.00cm, ±4.00cm, ±6.00cm, ±8.00cm and 10.00cm respectively. Thedevice when used ...
ABSTRACT This study reviewed the importance of hand washing and health benefits derived from the practice and also highlighted the consequences of not observing strict hand washing practice. Swabs from primary school pupils showed cfu mean total viable count of 1.60 x 104, 1.50 x 104, 1.60 x 104 and 1.7 x 104 across the four schools. Salmonella spp., Staphylococcus spp. and E. coli were the most sensitive microbes to the antibiotics used while Ciprofloxacin and Gentamicin were active across t...
