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

Syed Manzoorul Islam’s Postmodern Tales: A Study
No full textThe paper brings into focus how Syed Manzoorul Islam, in his three-decade-long literary career, has mastered a narrative style that sets him apart from many of his Bengali contemporaries. It demonstrates all the traits unique to his storytelling: blurring of boundaries between dream and reality, self-reflexivity, irony, and humor. The research also encapsulates how Syed Islam is different from his contemporary short story writers in terms of constructing plot and character. It foregrounds the author’s capability of developing a diction which is completely his own. The paper discusses the postmodern features prevailing in his stories. It shows us how the author invites the readers to be a part of his discourses. It summarizes the author’s surrealist imagination which creates a world that is strangely familiar and unfamiliar at the same time. Overall, the research analyzes how the postmodern elements relate to the major themes of Syed Manzoorul Islam’s short stories.Keywords: Post-modernism, magic-realism, realism, psychoanalysis, political degeneratio
Syed Abul Hasan Ali Hasani an-Nadwi Tentang Keruntuhan Peradaban, Pandangan Hidup, dan Pendidikan Islam
No full textThis article aims to explore Syed Hasan Ali Nadwi’s views on the decline of civilization and the notion of Islamic worldview. First, the author describes about Syed Hasan Ali Nadwi’s life in a short bio. Second, the author explores Syed Hasan Ali Nadwi’s views and thoughts about the essence beyond the civilizations, its glory and decadence. Then I will elaborate Syed Hasan Ali Nadwi’s point of view about the worldview of Islam, what are the substances of an Islamic worldview and how far the worldview could bring civilizations to certain glories and decadence. My point of view on this article is the stronger worldview that Muslims have, the stronger civilization Muslims could establish. It all depend on how Muslims face the crisis of knowledge and the loss of adab by the right ‘knowledge’, right ‘choice’, and right ‘action.â€
Nationalism, Patriotism and Political Ideas of Sir Syed Ahmad Khan: an Analysis
No full textSir Syed Ahmad Khan (Founder of Aligarh Muslim University) was born into a noble Muslim family in 1817; he was a distinguished scholar while working as a lawyer at the British East India Company. After realizing the worthless condition of Muslims, his approach to western education for the benefit of the Muslim community became a priority. This study contemplates that Sir Syed was religiously oriented and very politically aware of nationalism and patriotism. The author uses primary data and also secondary data. The author also explores his main books and articles; the author aims to examine Sir Syed's nationalist and political ideas concerning political significance for Muslims in India. The writer would like to know the result that, what is the reason, Sir Syed was against the Indian National Congress. At the same time, the whole Indian society was afraid of the British, but Sir Syed maintained his good relations with the British, and he also showed the loyalty of the Muslims towards them. This study found the conclusion about Sir Syed that he became a symbol of communal harmony.
Quality Control in Games Development
No full textThe purpose of this thesis was to provide more information regarding the role of quality control in game development to game industry professionals, game development start-ups and potential employees of this field. There are several misconceptions about this profession and this thesis contains information regarding the impact quality control has in games development.
The motivation to conduct this research and write this thesis comes from the author’s work experi-ence in testing games in a game development studio. From personal experience, the author had some misconceptions about this profession as well, which were cleared when she began working as a tester. The information regarding quality control is sparse compared to other aspects of game development.
This thesis was written using a qualitive research method where the sources were from data col-lection, online survey, printed and online literature. The results of this research outlined the dif-ferent methods of testing processes the quality control department must undergo to produce a feasible outcome for a game.
Quality control is one of the main aspects of game development, since this activity results in the discovery of bugs, establishing a defect database, and most importantly, the approval for a viable game to be published. Quality control does not cease when the game is released but continues postproduction as well.
The conclusion of this thesis report is that quality control is vital to the development of a game, although some game companies still do not view it as an important aspect for their games. In addition to hopefully clearing the misconceptions of people who want to follow this career path due to misunderstanding of the skills and knowledge required to be a games tester. Furthermore, an attempt to settle the mistaken belief that quality control is not a viable career path and people beginning at this position to gain a position in other departments of game development.
The author has signed a non-disclosure agreement with her employer. All information in this thesis that has been gathered from survey responses are taken from game industry professionals and are respectively referenced. Survey questions asked their opinions on quality control and when they feel testing is required most, whether quality control is required in start-ups, automated testing, and testers responsibility in detecting fun factor of the game
Muscle oxygen uptake differs from consumption dynamics during transients in exercise
No full textRelating external to internal respiration during exercise requires quantitative modeling analysis for reliable inferences with respect to metabolic rate. Often, oxygen transport and metabolism based on steady-state mass balances (Fick principle) and passive diffusion between blood and tissue are applied to link pulmonary to cellular respiration. Indeed, when the work rate does not change rapidly, a quasi-steady-state analysis based on the Fick principle is sufficient to estimate the rate of O2 consumption in working muscle. During exercise when the work rate changes quickly, however, non-invasive in vivo measurements to estimate muscle O2 consumption are not sufficient to characterize cellular respiration of working muscle. To interpret transient changes of venous O2 concentration, blood flow, and O2 consumption in working muscle, a mathematical model of O 2 transport and consumption based on dynamic mass balances is required. In this study, a comparison is made of the differences between simulations of O2 uptake and O2 consumption within working skeletal muscle based on a dynamic model and quasi-steady-state approximations. The conditions are specified under which the quasi-steadystate approximation becomes invalid
