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.

Dalam suatu "tjeramah pelantikan" jang diadakan bulan Djanuari jang lalu dalam ruangan auditorium dari Universiti tersebut, beliau memberikan ichtisar dari beberapa teorinja tentang periodisasi Sedjarah Asia Tenggara. Denys Lombard di- sini menjampaikan terdjemahannja dari beberapa bagian tjeramah itu; Prof. Al-Attas menentang para achli perihal India jang ter- lalu menondjolkan dan membesar2kan pentingnja djaman ,,Hindu Djawa", dan menundjukkan bahwa datangnja Islam adalah se- bagai tanda dari suatu revolusi mental jang besar dan satu2nja "pembaharuan" jang pernah terdjadi di Asia Tenggara. Teori itu dianggap terlalu berani oleh beberapa penentang dan sudah di- heboh2kan baru2 ini dalam lingkungan tjendekiawan Malaysia.III. 1. Prof. Syed M. Naguib Al-Attas, who teaches Malayan literature at the University Kebangsaan of Kuala Lumpur, is known for his studies on Malayan mysticism and his new ideas on the role of Islam in the Archipelago. On the occasion of his inaugural lesson, given last January, he summarized some of his principal conceptions; in a long text, some passages of which Denys Lombard has translated here, the author takes up a position against the Indianists who insist on exaggerating the importance of the "Indo-Javanese" period, and presents the arrival of Islam as marking a great intellectual revolution, the only ' renovation" worthy of the name that ever occurred in South-East Asia.Muhammad Naguib Al-Attas Syed.

Syed Ahmad and His Two Books Called ‘Asar-al-Sanadid’
No full textAbstractThe earliest writings of Sir Syed Ahmad Khan (1817–1898), the famous Muslim social reformer and educationist, were in the field of History, including two books on the monuments and history of Delhi that bear the same title, Asar-al-Sanadid. This paper compares the first book, published in 1847, with the second, published in 1854, to discover the author's ambitions for each. How do the two books differ from some of the earlier books of relatively similar nature in Persian and Urdu? How radically different are the two books from each other, and why? How and why were they written, and what particular audiences could the author have had in mind in each instance? How were the two books actually received by the public? And, finally, what changes do the two books reflect in the author's thinking? These are the chief questions that this paper seeks to explore.</jats:p
Diagnosis of Multiple-Voltage Design with Bridge Defect
No full textMultiple voltage is an effective dynamic power reduction design technique commonly used in low-power ICs. To the best of our knowledge, there is no reported work for diagnosing multiple-voltage enabled ICs, and the aim of this paper is to propose a method for diagnosing bridge defects in such ICs. By using synthesized ISCAS benchmarks, with realistic extracted bridges and a parametric fault model, this paper investigates the impact of varying supply voltage on the accuracy of diagnosis and demonstrates how the additional voltage settings can be leveraged to improve the diagnosis resolution through a novel multivoltage diagnosis algorithm. In addition, it also identifies the most useful voltage settings to reduce diagnosis cost by eliminating tests at certain voltage setting using the proposed multivoltage diagnosis approach, thereby achieving high diagnosis accuracy at reduced cost

Estimation of Value of Time for a Congested Network – A Case Study of the National Highway, Karachi
No full textAbstractTraffic congestion in mega cities is a common phenomenon for developing countries. Numerous studies on congestion cost estimation, that aim to quantify their monetary losses, have been conducted. Value of Time (VOT) assessment through utility maximizing theory and choice models are abundantly applied in transport literature. However, estimating VOT on congested network is not widely applied yet. To recognize the difference under normal and congested network, the current study focuses on VOT estimation for work trips in an extremely congested network.The focus of this research is to conduct a VOT estimation of the National Highway, Karachi. It connects Karachi city with Port Qasim Industrial area and the rest of the country. A large amount of freight transport to and from the port is also observed on this road. The National highway, being the only link to commute to this industrial area, is therefore under excessive traffic congestion.A stated preference (SP) survey was conducted at various industries located in this stretch. The respondents were asked about current travel practices and their (stated) preferences based on hypothetical -though realistic- travel attributes. A choice set of four alternative modes based on the currently used mode was presented to each individual. A Multinomial Logistics Regression (MNL) Model was developed for data analysis.As perceived, the results revealed a strong impact of travel time and travel cost on the (dis)utility of travel. These results can be utilized by policy makers to reduce congestion, monetary and time losses through efficient transport planning
