No full textSampled-Data Nonlinear Control of ECP-730 Magnetic Levitation System
No full textThis paper presents the idea of implementing various techniques related to sampled-data control for magnetic levitation systems. The control laws are designed to track time-varying signals and employ the feedback linearization technique based on the approximate discrete-time model. State feedback control is introduced with the gains adjusted via the pole placement method. A positional form proportional-integral-derivative (PID) control uses the trapezoidal summation for the integral term and the backward difference method for the derivative term. An input-output linearization feedback control is the most promising one, which incorporates the integrator in addition to the position error and velocity error. The integral action involves the manipulation of regulation error and reduces it with time to improve performance. Finally, controllers were tested in real time for practical demonstration along with a comparison for comprehensive analysis

Comparison of Diagnostic Performance of Soluble Transferrin Receptor and Soluble Transferrin Receptor-Ferritin Index Tests in the Diagnosis of Iron Deficiency Anemia
No full textIn this research article, a comprehensive analysis is performed to compare the diagnostic performance of soluble transferrin receptor (sTfR) and sTfR/log ferritin index tests in the differential diagnosis of iron deficiency anemia (IDA) and anemia of chronic disease (ACD). The analysis is performed for both sTfR and sTfR/log ferritin index using a set of 11 studies. The overall odds ratios for sTfR and sTfR/log ferritin index were 36.79 and 119.32 respectively, using 95% confidence interval. The relative sensitivity, specificity. positive likelihood ratio (LR) and negative LR values for sTfR in relation to sTfR/log ferritin index were 81% vs 85%, 84% vs 93%, 6.31 vs 13.95 and 0.18 vs 0.14 respectively. The summary receiver operating characteristic (SROC) curves are also plotted for both sTfR and sTfR/log ferritin index. The area under SROC curves for sTfR and sTfR/log ferritin index was found to be 0.9296 and 0.9825 respectively. Although both tests are useful, the sTfR/log ferritin index seems to be more effective when compared with sTfR

Does the participation in CSR activities enhance information diffusion? Evidence from US firms
No full textThe purpose of this paper is to investigate the impact of corporate social responsibility (CSR) on firm-specific information diffusion from 1,219 non-financial US firms between 2000 and 2012. By using Arellano-Bond dynamic panel-data estimation, we found evidence that suggests that stock prices of socially responsible firms have higher levels of firm-specific information diffusion. However, the size of firms plays a negative moderating role in this relationship. There is a positive and significant relationship between primary (technical) CSR activities and information diffusion among larger firms, while this relationship is reversed for secondary (institutional) CSR activities for similar firms. This study contributes to existing literature by providing empirical evidence on the CSR-Informativeness relationship, the moderating role of firm size and identifying the importance of primary stakeholders' CSR in US firms. This study has important policy implications for company management as it provides legitimacy to their CSR engagements, and to investors that CSR engagements should be considered as pricing factor
PRESIDENT OF PAKISTAN: A STUDY ON THE RIGHT OF PARDON
No full textThe administration of justice is firmest pillar of the government. The government is bound to dispense justice without any discrimination. Any person who has been convicted of crimes against state must be punished. Although the constitution of Pakistan grants power to president of Pakistan to pardon accused. But this power is subjected to some limitations as well and it should not be exercised arbitrarily. The presidential pardon must not be used as tool to protect those in power. Any decision to pardon convicted person is a slap on face of victim’s family. Because of misuse of power the victim’s family loose trust in judicial process. This paper analysis the powers of president of Pakistan regarding pardon. Discuss the concept of pardon in Islam. Further, discuss the cases where president of Pakistan granted pardon under what circumstances
The Political Thought of the Late H.H. Sheikh Zayed Bin Sultan Al Nahyan, Founder of the United Arab Emirates (1966 - 2004)
No full textThis thesis highlights the political thought of H.H. Sheikh Zayed Bin Sultan Al Nahyan, a man who made decisive contributions to the history of the twentieth century, and the various reflections of this political thought on the UAE, its people and the international community at large. In this regard, it explores and analyzes a multifaceted political thought that took its form in political practice in the establishment of the Federation, the management of crises and in the building of a prosperous enduring nation. Evaluating the factors that influenced the formation of the doctrinal matrix of Sheikh Zayed Bin Sultan Al Nahyan, this thesis traces the background from within which Sheikh Zayed’s leadership skills evolved and developed. From his early years onwards, Sheikh Zayed made a firm commitment to undertake the considerable task of building a fully fledged state out of a divided tribal background, improve the lives of citizens, and carve a place for the UAE in the international arena.
This research project illustrates the implications and dimensions of Sheikh Zayed's political thinking process exemplified in his discursive statements and actions. It documents and analyzes the career achievements of Sheikh Zayed, a statesman acknowledged by contemporary and future generations to have had significant impact on the political direction and overall development of the UAE. This impact also demonstrates the potential of his contribution to the field of political thought.
One of this study’s primary conclusions is that the accomplishments of Sheikh Zayed Bin Sultan Al-Nahyan during his rule have resulted primarily from his development of an integrated doctrine of governance that reflected his humanistic outlook. In this regard, at both the domestic and international levels, Sheikh Zayed’s political decisions and acts were undertaken with reference to this outlook
