Статья научная

Problem of queue management has been a great barrier to the financial institutions. Another way of measuring efficiency in banking industries is how fast the service of saving and withdraw is been rendered. Imagine customers that spend the whole day in the banking hall for one service or the other, due to poor service delivery and long stay on the queue will not hesitate to change his bank. Data was collected by direct observation in two banks, one old generation bank and one new generation bank, queue model and other statistical tools were used to analyze the data. Result of the analysis shows that Guaranty Trust Bank is more efficient than First Bank in that the later has a prolonged service time attributed to the preference of it by a pool of customers for many reasons.

Comparative Analysis of Steganography Technique for Information Security

Comparative Analysis of Steganography Technique for Information Security

Pooja Yadav, Sangeeta Dhall

Статья научная

Organisations need information security to reduce the risk of unauthorized information disclosure, use, modification and destruction. To avoid this risk and ensure security diverse solutions are available such as Cryptography, Steganography and Watermarking. Encryption changes the form of information but latter two hide records or watermark in some medium. This paper is an effort to explore one of the solutions i.e. Steganography. It is a mechanism of hiding secret information in text, image, audio or video carriers. Broadly, these are classified in various categories such as Spatial domain, Transform domain and Distortion Technique. This work intends to give an overview of above mentioned techniques in detail by comparing algorithms based on performance metrics such as Bhattacharyya Coefficient, Correlation Coefficient, Intersection Coefficient, Jaccard Index, MAE, MSE, PSNR and UIQI. After analysing the MATLAB simulation and comparison based on different performance metrics, LSB Substitution and Pseudorandom technique are best suited for generating highly matched stego image with respect to their cover image.

Comparative analysis of personnel distributions in the local government service in ekiti-state, nigeria, for service delivery

Comparative analysis of personnel distributions in the local government service in ekiti-state, nigeria, for service delivery

Olaniyan Joseph Olawale, Ademuyiwa A. Justus

Статья научная

It’s is no longer news that the Local Government (Third-tier of government in Nigeria) has not been able to optimally discharge its responsibilities according to its mandate. This had raised serious policy and research concerns that resulted to several reformative approaches in a bid to restructuring the system for efficient service delivery in the past decade. One major unpopular reason for inefficient service delivery was poor administration in the Local Government as a result of unbalanced distribution of personnel by cadre and gender in each local government in the state. This had not only hampered local government administration but also impeded adequate provision of expected services to local populace in line with its mandate as enshrined in the fourth schedule of the 1999 Constitution of the Federal Republic of Nigeria. Application of Statistical analysis using Chi-square Test of Independence showed that distribution of employees by cadre depends on local government in post in the year under study. Percentage distributions employed revealed that some local governments that are located around the capital city had more workers than those located outside the state capital city except some local governments with more viable socio-economic benefits. Sex ratio showed that there was gender imbalance as female personnel are more than their male counterpart in the local government service is.

Статья научная

In today's world, using quantitative methods are very important for financial markets forecast, improvement of decisions and investments. In recent years, various time series forecasting methods have been proposed for financial markets forecasting. In each case, the accuracy of time series methods fundamental to make decision and hence the research for improving the effectiveness of forecasting models have been curried on. In the literature, Many different time series methods have been frequency compared together in order to choose the most efficient once. In this paper, the performances of four different interval ARIMA-base time series methods are evaluated in financial markets forecasting. These methods are including Auto-Regressive Integrated Moving Average (ARIMA), Fuzzy Auto-Regressive Integrated Moving Average (FARIMA), Fuzzy Artificial Neural Network (FANN) and Hybrid Fuzzy Auto-Regressive Integrated Moving Average (FARIMAH). Empirical results of exchange rate forecasting indicate that the fuzzy artificial neural network model is more satisfactory than other models.

Comparison on Trapezoidal and Simpson’s Rule for Unequal Data Space

Comparison on Trapezoidal and Simpson’s Rule for Unequal Data Space

Md. Nayan Dhali, Mohammad Farhad Bulbul, Umme Sadiya

Статья научная

Numerical integration compromises a broad family of algorithm for calculating the numerical value of a definite integral. Since some of the integration cannot be solved analytically, numerical integration is the most popular way to obtain the solution. Many different methods are applied and used in an attempt to solve numerical integration for unequal data space. Trapezoidal and Simpson’s rule are widely used to solve numerical integration problems. Our paper mainly concentrates on identifying the method which provides more accurate result. In order to accomplish the exactness we use some numerical examples and find their solutions. Then we compare them with the analytical result and calculate their corresponding error. The minimum error represents the best method. The numerical solutions are in good agreement with the exact result and get a higher accuracy in the solutions.

Construction of Fractals based on Catalan Solids

Construction of Fractals based on Catalan Solids

Andrzej Katunin

Статья научная

The deterministic fractals play an important role in computer graphics and mathematical sciences. The understanding of construction of such fractals, especially an ability of fractals construction from various types of polytopes is of crucial importance in several problems related both to the pure mathematical issues as well as some issues of theoretical physics. In the present paper the possibility of construction of fractals based on the Catalan solids is presented and discussed. The method and algorithm of construction of polyhedral strictly deterministic fractals is presented. It is shown that the fractals can be constructed only from a limited number of the Catalan solids due to the specific geometric properties of these solids. The contraction ratios and fractal dimensions are presented for existing fractals with adjacent contractions constructed based on the Catalan solids.
