Human Capital and Economic Growth in Pakistan
No full textPakistan’s economy has grown faster on average than many other low- and middleincome countries over the past two decades. But several countries in Southeast Asia have fared even better. This paper focuses on factors that explain Pakistan’s relative growth performance. In addition to more traditional factors believed to determine growth, this paper looks particularly at the role of differences in the quality of human capital. The cross-country empirical results suggest that accumulation of physical capital and improvements in the quality of institutions have the largest pay-offs in terms of achieving higher growth, but that better education and health care also have a significant impact. Investment in these areas will increase the possibility of Pakistan entering a virtuous cycle of high growth and improved living conditions for the population.
Repetitive current control of two-level and interleaved three-phase PWM utility connected converters
No full textThis thesis is mainly concerned with investigations into digital repetitive current controlof two-level and interleaved utility connected PWM converters. The research ismotivated by the relatively poor performance of classical (PI) controllers when theutility voltage harmonic distortion is high. This is due to the low gain, and poordisturbance rejection of the PI controller at the utility harmonic frequencies. Repetitivefeedback controllers have the ability to track or reject periodic disturbances, such asutility harmonics, as they naturally have high gains at the utility voltage harmonicfrequencies, assuming that these frequencies do not change.Repetitive controllers (RC) are known for being sensitive to variations in systemparameters and disturbance frequency, which in practice renders them either ineffectiveor unstable. Another challenge arises from the memory requirements of RC in case ofthe absence of even harmonics, which can make its practical implementation difficultand expensive. In addition, another problem that has not been investigated extensivelyin the literature is that the effectiveness of RC is severely limited by the limitedbandwidth of the plant (the utility connected converter and its filter). Theoreticalanalysis and simulation results presented in this thesis show that RC could noteffectively reject disturbances at frequencies above the closed loop system bandwidth.The design of the converter's output filter bandwidth and the values of its componentsneed to be selected carefully, to enable RC to be used effectively.The research in this thesis focuses on investigating the practical implementation andperformance limits of two types of repetitive controllers (conventional and oddharmonics),used for current control of two-level utility connected converter with LCLoutput filter. The odd-harmonic repetitive controller halves the memory requirementand offers higher gains only at odd harmonic frequencies of interest. The overall controlscheme consists of the traditional classical tracking controller with a dual loop feedbacksystem and RC. The results indicate that the repetitive controller improves the steadystate error and the total harmonic distortion of the output current, provided that theplant's bandwidth is sufficiently large.Finally, a repetitive controller for an interleaved utility connected converter has beendesigned and investigated in this study. The interleaved converter system has higherbandwidth than the two-level converter, which improves the effectiveness of RC. Itprovides good disturbance rejection compared to classical controllers which results inlow output current THD. The RC was demonstrated to be robust despite uncertainty inutility impedance, while achieving a fast almost zero error convergence. The proposedRC has been experimentally implemented using a DSP and the results indicate that thequality of output current complies with international standards on harmonic limits andmatches simulation results obtained from the Matlab/Simulink model of the system
EXAMINING THE ROLE OF HAJI MUHAMMAD MOHSIN IN THE SOCIOECONOMIC LANDSCAPE OF 18TH CENTURY COLONIAL BENGAL: A COMPREHENSIVE ANALYSIS
No full textABSTRACT : 18th Century Bengal witnessed the stage from prosperity to decline , as per the statement of prominent historian Sushil Roy . This period saw the socio – economic condition of the people of Bengal under Mughal puppet emperors, next by independent Nawabs and later on by the colonial East India Company and in this socio-economic background the emergence of a great philanthropist Haji Muhammad Mohsin. In this paper the role of all these ruling classes including the role of colonial British East India Company in spreading Education and philanthropy has also been discussed critically. The role of Haji Muhammad Mohsin in this regard is highlighted and a comparative study of the Indigenous and colonial ruling class in case of spreading Education has been discussed. Attempts are also taken to find out the fact whether Haji Muhammad Mohsin was supported by the Colonial ruling class or interrupted by them in case of his continuing philanthropic activities. Apart from this , the role of contemporary wealthy persons and the role played by Haji Muhammad Mohsin’s regarding philanthropy has been discussed here. Haji Muhammad Mohsin longed for spreading Anglo – Persian Education . Secular characteristics of Haji Muhammad Mohsin and his contribution regarding the promotion of Education has been highlighted here.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Automated Disassembly of Waste Printed Circuit Boards: The Role of Edge Computing and IoT
No full textThe ever-growing volume of global electronic waste (e-waste) poses significant environmental and health challenges. Printed circuit boards (PCBs), which form the core of most electronic devices, contain valuable metals as well as hazardous materials. The efficient disassembly and recycling of e-waste is critical for both economic and environmental sustainability. The traditional manual disassembly methods are time-consuming, labor-intensive, and often hazardous. The integration of edge computing and the Internet of Things (IoT) provides a novel approach to automating the disassembly process, potentially transforming the way e-waste is managed. Automated disassembly of WPCBs involves the use of advanced technologies, specifically edge computing and the IoT, to streamline the recycling process. This strategy aims to improve the efficiency and sustainability of e-waste management by leveraging real-time data analytics and intelligent decision-making at the edge of the network. This paper explores the application of edge computing and the IoT in the automated disassembly of WPCBs, discussing the technological framework, benefits, challenges, and future prospects. The experimental results show that the YOLOv10 model achieves 99.9% average precision (AP), enabling accurate real-time detection of electronic components, which greatly facilitates the automated disassembly process

Kawasaki disease complicated by peripheral gangrene and a ventricular septal defect: An unusual association
No full textMohsin M, Akhtar S. Kawasaki disease complicated by peripheral gangrene and a ventricular septal defect: An unusual association. Turk J Pediatr 2019; 61: 301-304. Kawasaki disease is an acute febrile illness associated with the vasculitis of small and medium size arteries. Peripheral gangrene is very rare but a known complication of Kawasaki disease mostly reported in the infantile age group. Early therapy is advocated for prevention of serious complications. We report a 10-month-old girl with Kawasaki disease and a small ventricular septal defect who developed peripheral gangrene despite initiation of early therapy

Real-Time Detection of Electronic Components in Waste Printed Circuit Boards: A Transformer-Based Approach
No full textCritical Raw Materials (CRMs) such as copper, manganese, gallium, and various rare earths have great importance for the electronic industry. To increase the concentration of individual CRMs and thus make their extraction from Waste Printed Circuit Boards (WPCBs) convenient, we have proposed a practical approach that involves selective disassembling of the different types of electronic components from WPCBs using mechatronic systems guided by artificial vision techniques. In this paper we evaluate the real-time accuracy of electronic component detection and localization of the Real-Time DEtection TRansformer model architecture. Transformers have recently become very popular for the extraordinary results obtained in natural language processing and machine translation. Also in this case, the transformer model achieves very good performances, often superior to those of the latest state of the art object detection and localization models YOLOv8 and YOLOv9
