Fingerprint Detection Using Canny Filter and DWT, a New Approach
Islam, Md. Imdadul,Begum, Nasima,Alam, Mahbubul,Amin, M.R. Korea Information Processing Society 2010 Journal of information processing systems Vol.6 No.4
This paper proposes two new methods to detect the fingerprints of different persons based on one-dimensional and two-dimensional discrete wavelet transformations (DWTs). Recent literature shows that fingerprint detection based on DWT requires less memory space compared to pattern recognition and moment-based image recognition techniques. In this study four statistical parameters - cross correlation co-efficient, skewness, kurtosis and convolution of the approximate coefficient of one-dimensional DWTs are used to evaluate the two methods involving fingerprints of the same person and those of different persons. Within the contexts of all statistical parameters in detection of fingerprints, our second method shows better results than that of the first method.

<P>Herein, an alternative sulfonated poly(arylene ether ketone) (SPAEK)-cerium zirconium oxide nanotube (Ce2Zr2O7NT) composite (SPAEK/Ce2Zr2O7) membrane has been proposed as a potential polymer electrolyte membrane for all vanadium redox flow batteries (VRFBs) performance. The as-prepared composite membrane showed higher ion selectivity and reduced vanadium ion crossover than the pristine SPAEK and NRE-212 (Nafion-212) membranes in VRFB operation. The vanadium ion permeability rate of SPAEK/Ce2Zr2O7 (2%) composite membrane was found to be 27-fold and 12-fold lower than that of commercial NRE-212 and pristine SPAEK membranes, respectively. VRFBs operated with SPAEK/Ce2Zr2O7 (441 h) were shown to have a lower self-discharge rate than pristine SPAEK (172 h) and NRE-212 (42 h) membranes, respectively. Finally, an electrochemical test of VRFB exhibited high retention capacity after 100 cycles for SPAEK/Ce2Zr2O7 membrane as compared to NRE-212 and pristine SPAEK, while the coulombic efficiency (99.42%) at 40 mA cm<SUP>−2</SUP>. The structure and morphology of Ce2Zr2O7NT and the composite membrane were investigated by means of XRD, SEM, and TEM, and a consistent chemical structure of SPAEK/Ce2Zr2O7 (2%) composite membrane before and after the chemical stability test was confirmed using <SUP>1</SUP>H NMR. The composite with 2% filler exhibits improved thermal, mechanical, oxidative, and chemical stability with superior ion selectivity. Also, X-ray photoelectron spectroscopy (XPS) analysis of SPAEK/Ce2Zr2O7 (2%) composite membrane reveals the existence of a vanadium peak after 100 VRFB cycles.</P>
Oil Prices and Terms of Trade of Saudi Arabia: An Empirical Analysis
HAQUE, Mohammad Imdadul,IMRAN, Mohammad Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.9
Terms of trade is an important indicator of the welfare gains from international trade to the exporting country. Terms of trade of oil-exporting countries are hypothesized to depend primarily on oil prices. The study assesses the relation between oil prices and the terms of trade of Saudi Arabia. The study uses the Autoregressive Distributed Lag method to determine the cointegration between the country's terms of trade and oil prices for the period 2000-2018. The data for net barter terms of trade is taken from World Development Indicators and oil price is taken from Saudi Arabian Monetary Agency. The results show that oil prices and terms of trade are cointegrated and any disequilibrium between the two variables is corrected by 35% in a year. The study also reports a positive relationship between the two items, both in the short run and long run. Diagnostic tests indicate the model to be fit. The results suggest that, for a primarily oil-producing country like Saudi Arabia, the terms of trade depend on oil prices. The study fills the gap in the literature on the study of terms of trade for Saudi Arabia for the last few years, where there has been a high volatility in oil prices.
Performance Evaluation of the VoIP Services of the Cognitive Radio System, Based on DTMC
( Ummy Habiba ),( Imdadul Islam ),( M R Amin ) 한국정보처리학회 2014 Journal of information processing systems Vol.10 No.1
In recent literature on traffic scheduling, the combination of the two dimensional discrete-time Markov chain (DTMC) and the Markov modulated Poisson process (MMPP) is used to analyze the capacity of VoIP traffic in the cognitive radio system. The performance of the cognitive radio system solely depends on the accuracy of spectrum sensing techniques, the minimization of false alarms, and the scheduling of traffic channels. In this paper, we only emphasize the scheduling of traffic channels (i.e., traffic handling techniques for the primary user [PU] and the secondary user [SU]). We consider the following three different traffic models: the cross-layer analytical model, M/G/1(m) traffic, and the IEEE 802.16e/m scheduling approach to evaluate the performance of the VoIP services of the cognitive radio system from the context of blocking probability and throughput.

To enhance the utilization of the traffic channels of a network (instead of allocating radio channel to an individual user), a channel or a group of channels are allocated to a user group. The idea behind this is the statistical distribution of traffic arrival rates and the service time for an individual user or a group of users. In this paper, we derive the blocking probability and throughput of a subscriber station of Worldwide Interoperability for Microwave Access (WiMAX) by considering both the connection level and packet-level traffic under a complete partition scheme. The main contribution of the paper is to incorporate the traffic shaping scheme onto the incoming turbulent traffic. Hence, we have also analyzed the impact of the drain rate of the buffer on the blocking probability and throughput.
Traffic Analysis of a Cognitive Radio Network Based on the Concept of Medium Access Probability
( Risala T. Khan ),( Md. Imdadul Islam ),( M. R. Amin ) 한국정보처리학회 2014 Journal of information processing systems Vol.10 No.4
The performance of a cognitive radio network (CRN) solely depends on how precisely the secondary users can sense the presence or absence of primary users. The incorporation of a spatial false alarm makes deriving the probability of a correct decision a cumbersome task. Previous literature performed this task for the case of a received signal under a Normal probability density function case. In this paper we enhance the previous work, including the impact of carrier frequency, the gain of antennas on both sides, and antenna heights so as to observe the robustness against noise and interference and to make the correct decision of detection. Three small scale fading channels: Rayleigh, Normal, and Weibull were considered to get the real scenario of a CRN in an urban area. The incorporation of a maximal-ratio combining and selection combing with a variation of the number of received antennas have also been studied in order to achieve the correct decision of spectral sensing, so as to serve the cognitive users. Finally, we applied the above concept to a traffic model of the CRN, which we based on a two-dimensional state transition chain.
Antecedents of Entrepreneurial Intentions: A Comparative Study of Cultures
Mohammad Rumzi TAUSIF,Mohammad Imdadul HAQUE,M,Madhu Sudhan RAO,Md,Riyazuddin KHAN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.5
The study examines differences in entrepreneurial intentions and its antecedents across countries and cultures. This study uses Ajzen’s Theory of Planned Behaviour to compare the entrepreneurial intention of two diverse countries: Saudi Arabia and India. The study uses the non-parametric Mann Whitney U test and Structural Equation Modeling to analyze a sample of university students of the two countries. The study finds significant differences among the students of these two countries. The result indicates that entrepreneurial intention is higher in Indian students than their counterparts in Saudi Arabia. The result further indicates that attitude and perceived behavioral control explains entrepreneurial intention in both the countries. However, social norms are significant in explaining entrepreneurial intention only in India and not in Saudi Arabia. The findings of this study suggest that entrepreneurship has higher social approval in India when compared to Saudi Arabia. Social norms impact entrepreneurial intentions differently for India and Saudi Arabia. The study attributes the results to the differences in per capita income and socio-cultural norms in both countries. This study is one of the few that have explored cross-country entrepreneurial attributes as it addresses the research gap in terms of comparing entrepreneurial intentions of India and Saudi Arabia.
Environmental Sustainability Awareness in the Kingdom of Saudi Arabia
KHAN, Uzma,HAQUE, Mohammad Imdadul,KHAN, Aarif Mohammad Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.9
The study attempts to assess the level of environmental sustainability awareness in the Kingdom of Saudi Arabia. In the process, the study tries to assess the impact of extracurricular activities in increasing awareness of environmental sustainability. A survey questionnaire was administered to the students of Prince Sattam University and other universities of Saudi Arabia. The questionnaire comprises statements on simple environmental conservation activities, which we come across on a daily basis. Hypothesis testing is used to identify significant differences across different categories of respondents. Further, the method of binary logistic regression is used to analyze the data. Though all the respondents agree that conserving the environment is important still there are significant differences across categories when it comes to believing in and practicing environmentally-responsible behavior. The results show that environmental awareness can be increased using awareness activities on sustainability issues in a University setting. The study concludes that increasing the number of extracurricular activities on environmental topics as only 38% of the respondents reported any activity related to the environment in the past year. The findings of this study suggest that increased awareness of environmental issues can boost the sustainability awareness, which will ultimately lead to a sustainable environment.
