        Iqbal, Waheed,Jalil, Mudassar,Khadimallah, Mohamed A.,Hussain, Muzamal,Naeem, Muhammad N.,Al Naim, Abdullah F.,Tounsi, Abdelouahed Techno-Press 2021 Advances in nano research Vol.10 No.4

        In present study, the numerical investigations are carried out for effects of suction and blowing on boundary layer slip flow of casson nano fluid along permeable stretching cylinder in an exponential manner. The modeled PDEs are changed into nonlinear ODEs through appropriate nonlinear transformations. Change in physical quantities like friction coefficient, Nusselt and Sherwood numbers with variation of the aforementioned parameters are also examined and their numerical values are listed in the form of tables. Effects of Reynold number, suction parameter, Prandtl number, Lewis number, Brownian motion parameter and thermophoresis parameter are seen graphically with temperature profile.

      • Development of FPGA-based system for control of an Unmanned Ground Vehicle with 5-DOF Robotic Arm

        Abdullah Afaq,Mohammad Ahmed,Ahmed Kamal,Umar Masood,Muhammad Shahzaib,Nasir Rashid,Mohsin Tiwana,Javaid Iqbal,Asadullah Awan 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

        This paper discusses the development of a customizable FPGA based system for implementing control algorithms on an Unmanned Ground Vehicle (UGV) and its 5 Degree of Freedom (DOF) manipulator. The compact RIO-9012 is used as a controller which is a reconfigurable embedded control and acquisition system using LabVIEW as the programming platform. The developed system enables the control of UGV and its manipulator using a remote joystick controller via Wi-Fi communication. Apart from Joystick, the system can also be controlled optionally using a keyboard. Accuracy of Joystick control has been enhanced by using point to point mapping technique. A user friendly GUI has been developed to view live video feedback obtained from the onboard cameras to control the UGV accordingly. Different features of UGV like path tracker (tracks its path on Google Maps), variable speed modes, battery indicator, camera switch and selector etc. are also managed in the GUI. The system has been developed so that, in future, it can easily be extended to a fully autonomous system.

        Channel Allocation in Multi-radio Multi-channel Wireless Mesh Networks: A Categorized Survey

        ( Saleem Iqbal ),( Abdul Hanan Abdullah ),( Khalid Hussain ),( Faraz Ahsan ) 한국인터넷정보학회 2015 KSII Transactions on Internet and Information Syst Vol.9 No.5

        Wireless mesh networks are a special type of broadcast networks which cover the qualifications of both ad-hoc as well as infrastructure mode networks. These networks offer connectivity to the last mile through hop to hop communication and by comparatively reducing the cost of infrastructure in terms of wire and hardware. Channel assignment has always been the focused area for such networks specifically when using non-overlapping channels and sharing radio frequency spectrum while using multiple radios. It has always been a challenge for mesh network on impartial utilization of the resources (channels), with the increase in users. The rational utilization of multiple channels and multiple radios, not only increases the overall throughput, capacity and scalability, but also creates significant complexities for channel assignment methods. For a better understanding of research challenges, this paper discusses heuristic methods, measurements and channel utilization applications and also examines various researches that yield to overcome this problem. Finally, we highlight prospective directions of research.

      • Flow of casson nanofluid along permeable exponentially stretching cylinder: Variation of mass concentration profile

        Waheed Iqbal,Mudassar Jalil,Mohamed A. Khadimallah,Muzamal Hussain,Muhammad N. Naeem,Abdullah F. Al Naim,S.R. Mahmoud,Abdelouahed Tounsi 국제구조공학회 2021 Steel and Composite Structures, An International J Vol.38 No.1

        The Runge-Kutta method of 6th-order has been employed in this paper to analyze the flow of Casson nanofluid along permeable exponentially stretching cylinder. The modeled PDEs are changed into nonlinear ODEs through appropriate nonlinear transformations. The aim of the paper is to investigate the effects of different parameters such as Casson fluid parameter, slip parameter, suction parameter, Prandtl number, Lewis number, Brownian motion parameter, and thermophoresis parameter, with the variation of mass concentration profile. Numerical results are attained using a renowned numerical scheme shooting technique and for the authenticity of present methodlogy, the results are verified with earlier open text.

      • Directional Age-Primitive Pattern (DAPP) for Human Age Group Recognition and Age Estimation

        Bin Iqbal, Md Tauhid,Shoyaib, Mohammad,Byungyong Ryu,Abdullah-Al-Wadud, M.,Oksam Chae IEEE 2017 IEEE transactions on information forensics and sec Vol.12 No.11

        <P>An appropriate aging description from face image is the prime influential factor in human age recognition, but still there is an absence of a specially engineered aging descriptor, which can characterize discernible facial aging cues (e.g., craniofacial growth, skin aging) from a detailed and more finer point of view. To address this issue, we propose a local face descriptor, directional age-primitive pattern (DAPP), which inherits discernible aging cue information and is functionally more robust and discriminative than existing local descriptors. We introduce three attributes for coding the DAPP description. First, we introduce Age-Primitives encoding aging related to the most crucial texture primitives, yielding a reasonable and clear aging definition. Second, we introduce an encoding concept dubbed as Latent Secondary Direction, which preserves compact structural information in the code avoiding uncertain codes. Third, a globally adaptive thresholding mechanism is initiated to facilitate more discrimination in a flat and textured region. We apply DAPP on separate age group recognition and age estimation tasks. Applying the same approach to both of these tasks is seldom explored in the literature. Carefully conducted experiments show that the proposed DAPP description outperforms the existing approaches by an acceptable margin.</P>

        Evaluation of different milking practices for optimum production performance in Sahiwal cows

        Aslam, Naveed,Abdullah, Muhammad,Fiaz, Muhammad,Bhatti, Jalees Ahmad,Iqbal, Zeeshan Muhammad,Bangulzai, Nasrullah,Choi, Chang Weon,Jo, Ik Hwan Korean Society of Animal Sciences and Technology 2014 한국축산학회지 Vol.56 No.4

        The production performance of multiparous lactating Sahiwal cows (n = 24) was evaluated according to both milking frequency and method. Selected animals were randomly divided into four groups containing six animals each under a completely randomized design. Cows in groups A & B were milked by the hand milking method three times per day, respectively. Similarly, cows in groups C & D were milked by the machine milking method two and three times per day, respectively. All animals were maintained under uniform feeding and management conditions. Dry matter intake was high in animal groups milked three times per day, and it remained unchanged between the hand and machine milking methods. Milk yield was higher (P < 0.05) in cows milked three times compared to those milked twice per day, and it did not differ between hand and machine milking methods. Milk fat percentage was higher (P < 0.05) in cows milked twice per day compared to those milked three times using both machine and hand milking methods. The percentage of total solids showed a similar pattern as the fat percentage. However, percentages of protein, lactose, and non-fat solids in milk were not significantly different (P > 0.05) among the treatment groups. Collectively, the results show that milking three times per day instead of twice at 8-hour intervals can enhance milk yield in Sahiwal cows using both hand and machine milking methods.

      • 영문지(JAST)게재논문 : Sahiwal 젖소의 최적 유생산을 위한 착유방법 측정 연구

        ( Naveed Aslam ),( Muhammad Abdullah ),( Muhammad Fiaz ),( Jalees Ahmad Bhatti ),( Zeeshan Muhammad Iqbal ),( Nasrullah Bangulzai ),최창원 ( Chang Weon Choi ),조익환 ( Ik Hwan Jo ) 한국동물자원과학회(구 한국축산학회) 2014 축산기술과 산업 Vol.5 No.2

        24두의 Sahiwal 젖소를 대상으로 착유횟수와 방법에 의한 생산량 변화를 측정하였다. 선발된 시험축은 완전임의배치법으로 6두씩 4그룹으로 공시되었다. A와 B 그룹의 젖소들은 손 착유법으로 착유하되 각각 일일 2회 및 3회 착유하였고 C와 D그룹의 젖소들은 기계 착유법으로 착유하되, 각각 일일 2회 및 3회 착유 하였다. 전 두수는 동일한 사료와 사양관리 하에서 유지되었다. 건물 섭취량은 일일 3회 착유하는 그룹에서 높게 나타났고 이것은 손 착유법과 기계 착유법 간에도 차이를 보이지 않았다. 일일 2회 착유와 비교해서 일일 3회 착유 시 유량이 높았고(P<0.05), 손 착유법와 기계 착유법 간의 차이는 없었다. 손 착유법과 기계 착유법을 이용한 그룹 모두에서 유지방 비율은 일일 3회 착유보다 2회 착유 시 높게 나타났고(P<0.05), 총고형물 비율 역시 유지방 비율과 비슷한 패턴을 보였다. 하지만, 단백질, 유당, 무지고형물 비율들은 시험구간 유의적 차이를 보이지 않았다(P>0.05). 결론적으로 본 연구결과는 Sahiwal 젖소에 있어서 8시간 간격으로 2회 착유하는 것보다 3회 착유하는 것이 손 착유법이나 기계 착유법 모두에서 유량을 극대화할 수 있는 방법임을 보여주고 있다.

        Quality Assessment of Beef Using Computer Vision Technology

        Md,Faizur Rahman,Abdullah Iqbal,Md,Abul Hashem,Akinbode A,Adedeji 한국축산식품학회 2020 한국축산식품학회지 Vol.40 No.6

        Imaging technique or computer vision (CV) technology has received huge attention as a rapid and non-destructive technique throughout the world for measuring quality attributes of agricultural products including meat and meat products. This study was conducted to test the ability of CV technology to predict the quality attributes of beef. Images were captured from longissimus dorsi muscle in beef at 24 h post-mortem. Traits evaluated were color value (L*, a*, b*), pH, drip loss, cooking loss, dry matter, moisture, crude protein, fat, ash, thiobarbituric acid reactive substance (TBARS), peroxide value (POV), free fatty acid (FFA), total coliform count (TCC), total viable count (TVC) and total yeast-mould count (TYMC). Images were analyzed using the Matlab software (R2015a). Different reference values were determined by physicochemical, proximate, biochemical and microbiological test. All determination were done in triplicate and the mean value was reported. Data analysis was carried out using the programme Statgraphics Centurion XVI. Calibration and validation model were fitted using the software Unscrambler X version 9.7. A higher correlation found in a* (r=0.65) and moisture (r=0.56) with ‘a*’ value obtained from image analysis and the highest calibration and prediction accuracy was found in lightness (r²c=0.73, r²p=0.69) in beef. Results of this work show that CV technology may be a useful tool for predicting meat quality traits in the laboratory and meat processing industries.

      • Score Based Risk Assessment of Lung Cancer and its Evaluation for Bangladeshi People

        Mukti, Roushney Fatima,Samadder, Pratul Dipta,Emran, Abdullah Al,Ahmed, Farzana,Imran, Iqbal Bin,Malaker, Anyanna,Yeasmin, Sabina Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.17

        Background: The problem of cancer, especially lung cancer, is very acute in Bangladesh. The present study was conducted to evaluate the risk of lung cancer among Bangladeshi people based on hereditary, socio-economic and demographic factors. Materials and Methods: This study was carried out in 208 people (patients-104, controls-104) from January 2012 to September 2013 using a structured questionnaire containing details of lung cancer risk factors including smoking, secondhand smoke, tobacco leaf intake, age, gender, family history, chronic lung diseases, radiotherapy in the chest area, diet, obesity, physical activity, alcohol consumption, occupation, education, and income. Descriptive statistics and testing of hypotheses were used for the analysis using SPSS software (version 20). Results: According to this study, lung cancer was more prevalent in males than females. Smoking was the highest risk factor (OR=9.707; RR=3.924; sensitivity=0.8872 and P<0.0001) followed by previous lung disease (asthma, tuberculosis etc.) (OR=7.095; RR=1.508; sensitivity=0.316 and P<0.0001)) for male patients. Highly cooked food (OR=2.485; RR=1.126; sensitivity=0.418 and P=0.004)) and also genetic inheritance (OR=1.93; RR=1.335; sensitivity=0.163 and P=0.138) demonstrated significant correlation with lung cancer as risk factors after these two and alcohol consumption was not prevalent. On the other hand, for female patients, tobacco leaf intake represented the highest risk (OR=2.00; RR=1.429; sensitivity= 0.667 and P=0.5603) while genetic inheritance and highly cooked food also correlate with lung cancer but not so significantly. Socioeconomic status and education level also play important roles in causing lung cancer. Some 78.5% male and 83.3% of female cancer patients were rural residents, while 58.2% lived at the margin or below the poverty line. Most male (39.8%) and female (50.0%) patients had completed only primary level education, and 27.6% male and 33.3% female patients were illiterate. Smoking was found to be more prevalent among the less educated persons. Conclusions: The results obtained in this study indicate the importance of creating awareness about lung cancer risk factors among Bangladeshi people and making appropriate access to health services for the illiterate, poor, rural people.
