A Third Sector-Led Economic Model: Scopes of Islamic Entrepreneurship

Abstract: Private (first sector) and public (second sector) sector economics, both individually and jointly, have failed to ensure the wellbeing of human societies on the national and global levels. In response, social enterprise (third sector) economics, which features cooperatives and not-for-profit social enterprises, foundations (awqāf), and similar undertakings, has emerged as a make-up strategy in an attempt to counter the deficiencies of the market-state economic model. However, there is a strongly felt belief that the third sector needs to be broadened and mainstreamed in order to include both not-for-profit and for-profit businesses blended with social justice (via provision of such social welfare programs as corporate social responsibility) so that they can play a major role in poverty alleviation and economic growth. Islamic entrepreneurship, which is basically a community-centric mode of business initiative, is an antidote to the problem of intolerable economic and social dualism, a natural strategy against all forms of capitalist exploitation and attempts to control a nation’s resources. Moreover, it is the natural model for solving economic inequity, wealth concentration, and social divides. Based on its potential and using examples from Bangladesh and Malaysia, we present the Islamic style of entrepreneurship. We contend that this particular style is the most efficient and desirable one for effectively widening and mainstreaming community-centric third sector economics so that it can ensure development with equity and social justice especially in developing countries.

Comparative Experimental Analysis with and without Proposed Algorithm for MPPT using a DC-DC Converter for PV Array

Abstract: Solar Photovoltaic (PV) array is an enormous source of green energy generation. Low efficiency and high cost is the great challenge of the solar systems. Various power electronic converter and algorithms are design to mitigate this challenge, Perturb and Observe (P&O) algorithm is one of them. In this paper a proposed algorithm is implemented through DC-DC converter. This proposed algorithm allows the PV array to work at its highest efficiency. Results from experiments show that the proposed MPPT algorithm improves overall system efficiency which is 89.37% higher compared to non MPPT System. To maximize the efficiency of the PV panel from zero to the maximum output, the entire range of the duty cycle needs to be used for the implementation of the proposed MPPT algorithm. In addition to this, a microcontroller based control system has been used in this work.

Addiction: Law and Practice in Bangladesh

Abstract: In Bangladesh addiction has come as a dreadful curse on social life. Being addicted to intoxicant, men are extremely demoted. As a result frustration, indiscipline & mournful ripeness/end fall in personal life as well as its horrendous impact fall in social life and national life. Consequently the youths, the future of the nation, are running to the depth of darkness. This article explores the origin and causes of addiction and its bad impact on social life. This paper also highlights the national laws and Islamic laws about addiction and tries to show the present practice in Bangladesh. This article ends suggesting the Government how to overcome this problem. doi: 10.3329/iiucs.v4i0.2855 IIUC STUDIES Vol. - 4, December 2007 (p 59-70)

Miniaturized planar Inverted-F antenna for Off-body wireless body area network (WBAN) application

Abstract: This paper proposes the design and simulation of a novel miniaturized Planar Inverted-F Antenna (PIFA) with a slotted radiating patch, having a low specific absorption rate (SAR). The operating frequency spectrum of the antenna is 2.34-2.58 GHz, which makes it perfectly suitable for applications in the Industrial, Scientific and Medical (ISM) band (2.4-2.4835 GHz). The designed antenna has a very tiny structure with dimensions of 8 mm × 9 mm × 1.5 mm. While comparing with a few other antennas, the size was found to be considerably reduced by 56.80%. SAR measurement of this antenna has been done by designing six layer human head & human arm models, using Electromagnetic (EM) software HFSS, to study the interaction between the proposed antenna and human body tissues. The electric field distribution in the designed human head and human arm models are also shown to estimate the penetration of the field at 2.45 GHz, when the antenna is placed at a distance of 5mm from the designed models. The SAR analysis shows that though the Local SAR values in some of the layers of the designed human head and arm models are higher, the average SAR values in all the six layers of both the designed models are acceptable under the standard limits.

An Approach to Performance and Qualitative Analysis of Routing Protocols on IPv6

Abstract: Real time applications are gaining popularity due to the availability of high-speed Internet facilities, and thereby it is being deployed massively on IPv6 platform. Video streaming is one of the most popular sectors among the real time applications arena. Quality of service (QoS) requirement must be satisfied for the proper enjoyment of video streaming services. Proper network resource management and planning are must for providing optimum services which can be achieved by the selection of proper routing protocol. For this reason, in this paper, the IPv6 network scenario is considered for three different popular routing protocols which are RIPng, OSPFv3 and EIGRP. The simulation is done by using OPNET simulator. Packet loss, end to end delay, delay variation, jitter and MOS value are simulated as our metrics to evaluate the performance of the IPv6. The simulation results show that the RIPng outperforms EIGRP, OSPFv3 and hybrid protocol (RIPng_OSPFv3).
