The Educational Thinking of Bashir Al-Ibrahimi (1965 -1889)
No full text The educational thought of Al-Bashir Al-Ibrahimi was focused on the formation, formation, and preparation of a Muslim generation in an integrated manner from all stages of individual psychological, mental, cognitive, and social development, in accordance with Islamic values and principles that are closely aligned with and compatible with modern education. Accordingly, education was linked to Sheikh Al-Bashir Al-Ibrahimi on scientific grounds that carry all the parameters of changefor an individual or society. This great interest by Al-Ibrahimi to the elements
educational science from the teacher and the learner and a transition to educational content indicates a conclusive indication of the Sheikh\u27s insightful view of building the liberal thought of the learner. Hence, we strive through this article to answer the following basic problem: What are the most important educational ideas that we find in the effects of Al-Bashir Al-Ibrahimi? And to what extent are they compatible with the principles and ideas of modern education
A Fast and Accurate Process Variation-aware Modeling Technique for Resistive Bridge Defects
No full textRecent research has shown that tests generated without taking process variation into account may lead to loss of test quality. At present there is no efficient device-level modeling technique that models the effect of process variation on resistive bridge defects. This paper presents a fast and accurate technique to achieve this, including modeling the effect of voltage and temperature variation using BSIM4 transistor model. To speedup the computation time and without compromising simulation accuracy (achieved through BSIM4) two efficient voltage approximation algorithms are proposed for calculating logic threshold of driven gates and voltages on bridged lines of a fault-site to calculate bridge critical resistance. Experiments are conducted on a 65-nm gate library (for illustration purposes), and results show that on average the proposed modeling technique is more than 53 times faster and in the worst case, error in bridge critical resistance is 2.64% when compared with HSPICE
Low-energy standby-sparing for hard real-time systems
No full textTime-redundancy techniques are commonly used in real-time systems to achieve fault tolerance without incurring high energy overhead. However, reliability requirements of hard real-time systems that are used in safety-critical applications are so stringent that time-redundancy techniques are sometimes unable to achieve them. Standby sparing as a hardware redundancy technique can be used to meet high reliability requirements of safety-critical applications. However, conventional standby-sparing techniques are not suitable for low-energy hard real-time systems as they either impose considerable energy overheads or are not proper for hard timing constraints. In this paper we provide a technique to use standby sparing for hard real-time systems with limited energy budgets. The principal contribution of this work is an online energy management technique which is specifically developed for standby-sparing systems that are used in hard real-time applications. This technique operates at runtime and exploits dynamic slacks to reduce the energy consumption while guaranteeing hard deadlines. We compared the low-energy standby-sparing (LESS) system with a low-energy time redundancy system (from a previous work). The results show that for relaxed time constraints, the LESS system is more reliable and provides about 26% energy saving as compared to the time-redundancy system. For tight deadlines when the time redundancy system is not sufficiently reliable (for safety-critical application), the LESS system preserves its reliability but with about 49% more energy consumptio
Numerically efficient modeling of CNT transistors with ballistic and non-ballistic effects for circuit simulation
No full textThis paper presents an efficient carbon nanotube (CNT) transistor modeling technique which is based on cubic spline approximation of the non-equilibrium mobile charge density. The approximation facilitates the solution of the selfconsistent voltage equation in a carbon nanotube so that calculation of the CNT drain-source current is accelerated by at least two orders of magnitude. A salient feature of the proposed technique is its ability to incorporate both ballistic and nonballistic transport effects without a significant computational cost. The proposed models have been extensively validated against reported CNT ballistic and non-ballistic transport theories and experimental results
Application of Analog Adaptive Filters for Dynamic Sensor Compensation
No full textThis paper investigates the application of analog adaptive techniques to the area of dynamic sensor compensation, of which there is little reported work in the literature. The case is illustrated by showing how the response of a load cell can be improved to speed up the process of measurement. The load cell is a sensor with an oscillatory output in which the measurand contributes to the response parameters. Thus, a compensation filter needs to track variation in measurand whereas a simple, fixed filter is only valid at one specific load value. To facilitate this investigation, computer models for the load cell and the adaptive compensation filter have been developed. To allow a practical implementation of the adaptive techniques, a novel piecewise linearization technique is proposed in order to vary a floating voltage-controlled resistor in a linear manner over a wide range. Simulation and practical results are presented, thus demonstrating the effectiveness of the proposed techniques

Synchronization Overhead in SOC Compressed Test
No full textTest data compression is an enabling technology for low-cost test. Compression schemes however, require communication between the system under test and the automated test equipment. This communication, referred to in this paper as synchronization overhead, may hinder the effective deployment of this new test technology for core-based systems-on-a-chip. This paper analyzes the sources of synchronization overhead and discusses the different trade-offs, such as area overhead, test time and automatic test equipment extensions. A novel scalable and programmable on-chip distribution architecture is proposed, which addresses the synchronization overhead problem and facilitates the use of low cost testers for manufacturing test. The design of the proposed architecture is introduced in a generic framework, and the implementation issues (including the test controller and test set preparation) have been considered for a particular case

The book is among the most well-known, well-read and most-cited authorities on Islamic rituals in northern Nigeria and West Africa. Considered more advanced than Qawā’id and Al-Akhdarī, Al-ʿAshmāwī is popular among clerics and students of Islamic jurisprudence. Like Al-Akhdarī and other similar books on Muslim rituals, this text contains many chapters dealing with the significance of good intent, purification of the heart, body, and the environment, ablution and ritual prayers, requirements of ritual prayers, factors that invalidate ritual prayers, and common mistakes in ritual prayers and how to correct them.The contents of this collection were developed with support of the Title VI National Resource Center grant # P015A180164 from the U.S. Department of Education.

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
