Naqi in listed in the 1979-1980 Faculty Directory with the following information. "Associate Professor of Veterinary Microbiology & Parasitology; B.V.Sc. (D.V.M.)-Osmania U. (India)1961; M.S. 1967 and Ph.D. 1969 in Veterinary Microbiology and Immunology at Texas A&M ; Diplomate, A.C.V.M." As of 2017 he was listed as an Adjunct Professor in the Department of Veterinary Pathobiology. One of his special areas of study is Avian medicine. He left Texas in 1987 to join the faculty at Cornell University and as of 2016 was teaching Microbiology and Immunology at Weill Cornell Medicine-Qatar.
"Syed had an interesting history. After completing his veterinary training at Osmania University in India, he took a position as a Research Associate with the US Agency for International Development (USAID) India Program, managing a large poultry operation in that country. Dr. Earl Moore, who had been on the Cornell faculty as a turkey pathologist in the late 1940s and early 1950s, was in India at the time working with the USAID program helping to modernize the poultry Industry. He met Dr. Naqi and, impressed with his abilities, convinced him to come to the United States for advanced work in avian medicine. Syed did so, earning an MS (1967) and a PhD (1969) at Texas A&M University and ultimately joining the avian disease faculty there. Thus, there was a link between Naqi and Calnek in that they both were indebted to Earl Moore for the nudges that teered them into research careersin avian medicine. Dr. Naqi gained a strong reputation for both his teaching and his research skills and represented an ideal addition to our faculty. Accordingly, he was aggressively recruited and was appointed as a Full Professor with tenure." [Calnek, Bruce W. , A History of Avian Medicine at Cornell University 1898-2008.

Modeling of impact dynamics of tennis ball with a flat surface
No full textA two-mass model with a spring and a damper in the vertical direction, accounting for vertical translational motion and a torsional spring and a damper connecting the rotational motion of two masses is used to simulate the dynamics of a tennis ball as it comes into contact with a flat surface. The model is supposed to behave as a rigid body in the horizontal direction. The model is used to predict contact of the ball with the ground and applies from start of contact to end of contact. The springs and dampers for both the vertical and the rotational direction are linear. Differential equations of motion for the two-mass system are formulated in a plane. Two scenarios of contact are considered: Slip and no-slip. In the slip case, Coulomb??s law relates the tangential contact force acting on the outer mass with the normal contact force, whereas in the no-slip case, a kinematic constraint relates the horizontal coordinate of the center of mass of the system with the rotational coordinate of the outer mass. Incorporating these constraints in the differential equations of motion and applying initial conditions, the equations are solved for kinematics and kinetics of these two different scenarios by application of the methods for the solutions of second-order linear differential equations. Experimental data for incidence and rebound kinematics of the tennis ball with incidence zero spin, topspin and backspin is available. The incidence angles in the data range from 17 degrees up to 70 degrees. Simulations using the developed equations are performed and for some specific ratios of inner and outer mass and mass moments of inertia, along with the spring-damper coefficients, theoretical predictions for the kinematics of rebound agree well with the experimental data. In many cases of incidence, the simulations predict transition from sliding to rolling during the contact, which is in accordance with the results obtained from available experimental measurements conducted on tennis balls. Thus the two-mass model provides a satisfactory approximation of the tennis ball dynamics during contact

ELECTROMAGNETIC RESPONSE OF A CIRCULAR DB CYLINDER IN THE PRESENCE OF CHIRAL AND CHIRAL NIHILITY METAMATERIALS
No full textScattering of electromagnetic plane wave from an infinitely long circular DB cylinder placed in chiral and chiral nihility metamaterials is studied, and the results are compared with that of scattering from DB cylinder placed in free space. The discussion is further extended by considering coating of DB cylinder with chiral/chiral nihility metamaterial. For DB cylinder placed in unbounded free space/chiral/chiral nihility metamterial, only co-polarized scattered fields are obtained, whereas, for chiral/chiral nihility metamaterial coated case, both co- and cross-polarized scattered fields are noted. Numerical results are presented for different values of chirality parameter
Mediapipe based Preprocessed VGGFace2 Dataset
No full textVGGFace2 Dataset and Face Mesh PreprocessingIntroductionThe VGGFace2 dataset is a large-scale face recognition dataset containing over 3.31 million images of 9,131 identities, with an average of 362 images per identity. The dataset is designed to include extensive variations in pose, age, illumination, ethnicity, and profession, making it one of the most diverse and challenging face recognition datasets available. For more details, please refer to the original publication:VGGFace2: A dataset for recognizing faces across pose and age - DOI: 10.48550/arXiv.1710.08092
Preprocessing Using MediaPipe 3D Face MeshOn this dataset, we applied the MediaPipe-based 3D face mesh algorithm to accurately detect faces while removing all background elements, including hair. Our preprocessing strictly retained facial landmarks, ensuring that only the essential facial features were preserved. This approach significantly enhanced the accuracy and generalization of our model, as the model was trained exclusively on landmark-based facial data.
Training and PerformanceThe preprocessed data was utilized to train Xception model, which resulted in remarkably accurate outcomes due to the strictly landmark-based facial representation. The model demonstrated robust performance including explainable-AI, proving that eliminating unnecessary background elements contributed positively to its efficiency and reliability.

Safety of medical device users: A study of physiotherapists’ practices, procedures and risk perception
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Aims: To study practices and procedures with respect to electrotherapy in physiotherapy departments and to study physiotherapists’ perception of health risk, health consequences and protection of health from different risks including electromagnetic field emissions from electrotherapy devices.
Methods: This cross-sectional study was conducted in three phases from June 2002 to December 2003. The first phase was an audit of the practices and procedures regarding electrotherapy in National Health Service physiotherapy departments (N = 46 including 7 departments in pilot study) located in 12 counties in the southeast and southwest of England including Greater London. The second phase comprised one observational visit to each of the same physiotherapy departments to characterise their occupational environment. The third phase was a questionnaire survey of 584 physiotherapists working in these departments. Variables concerned perception of health risk, health consequences and protection of health associated with different risk factors.
Results: In the first two phases, the recruitment rate of the departments was 80.7% (46 out of 57) and response rate of those recruited was 100% (n=46). The response rate for the last phase of the study was 66.8% (390 out of 584). Results of the practices and procedures audit show that ultrasound was the most common form of electrotherapy while microwave diathermy was neither available nor used in these departments. Pulsed shortwave diathermy was used 4-5 days per week while continuous shortwave diathermy was used rarely. Electrotherapy was provided to up to 50% of patients per week in the departments. The observational visits to the departments revealed that there were metallic objects within close proximity of diathermy equipment and wooden treatment couches for treatment with PSWD and CSWD were rare. The risk perception survey showed that physiotherapists generally perceived a moderate health risk and health consequences (harm) from exposure to EMF emissions from electrotherapy devices. Protection from EMFs in physiotherapy departments was generally perceived as ‘usually’ possible.
Conclusions: Physiotherapy departments report safe electrotherapy practices. Use of diathermy devices that use RF EMFs is declining. The key predictors of physiotherapists’ perception of health risk were perception of health consequences and vice versa. Gender was a significant predictor of the perception of health risks and health consequences. The main predictor of perception of protection against risk was the knowledge of environmental and health issues. Latent dimensions of perceptions of health risk, health consequences and protection from risk were identified and confirmed and their predictors were determined.Brunel Universit

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
