Noor Jamaliah Ibrahim

Speech processing for Quranic Arabic is an active field of research, since a few years ago. We propose in this paper, a review on the potential of automatic speech recognition (ASR) computer-based technology to support Quranic learning processes. Thus, the aspects of Computer-Aided Pronunciation Learning (CAPL) are discussed, focusing towards the implementation on Quranic learning through Al-Jabari method. We believe Al-Jabari method is fast and efficient, as well as a practical way of learning Al-Quran. The analysis of CAPL systems towards the implementation in Quranic learning through Al-Jabari method are discussed in details.

Energy Conservation Day: Symbolism Doesn’T Pay, Hippu Salk Kristle Nathan

Hippu Salk Kristle Nathan

The much publicised panting competition at school level on the occasion of Energy Conservation Day was a good effort to send message to consumers to influence their energy consumption behaviour. But the effect is minuscule.

As a child one might have walked or cycled to school. But as a breadwinner, once energy related decisions largely get influenced by one's income level and opportunities and restrictions.

Understanding the levels and movements of particulate matter in an enclosed space can lead to a reduction in the impact of this material on health and experimental results. A system of environmental sensors including particulate matter, selected gasses, humidity, temperature, and pressure can be used to assist in tracking air movement, providing real-time mapping of potential contaminants as they move through a space. In this paper we present a system that is capable of sensing these environmental factors, collecting data …

H-Matrix-Based Fast Direct Finite Element Solver For Large-Scale Electromagnetic Analysis, Haixin Liu, Dan Jiao

Haixin Liu

In this work, we prove that the sparse matrix resulting from a finite-element-based analysis of electrodynamic problems can be represented by an H-matrix without any approximation, and the inverse of this sparse matrix has a data-sparse H-matrix approximation with error well controlled. Based on this proof, we develop an H-matrix-based direct finite-element solver of O(kNlogN) memory complexity and O(k2Nlog2N) time complexity for solving electromagnetic problems, where k is a small variable that is adaptively determined based on accuracy requirements, and N is the number of unknowns. Both inversebased and LU-based direct solutions are developed. The LU-based solution is further accelerated …

Power Efficient Optimized Arithmetic And Logic Unit Design On Fpga, Innovative Research Publications Irp India, Siddharth Singh Parihar, Prof. Rajni Gupta Gupta

Innovative Research Publications IRP India

This paper deals with low power ALU design and its implementation on 90nm Spartan 3 FPGA. Most of power is consumed in ALU in any processor and hence reduction in ALU power is needed. In this work, we have designed a low power ALU. To reduce dynamic power consumption we disabled the blocks which are not needed in currently selected operation. Also hardware is reused; this will cut down the FPGA resource usage and also reduce the power consumption. By using these methods dynamic power consumption is reduced and less FPGA resources were consumed.

A New Compensation Technique For Stable The Gain Of Sub-Micron Amplifiers, Innovative Research Publications Irp India, Billu. Balaji, Dr.V. Thrimurthulu, L.Mihira Priya

Innovative Research Publications IRP India

Process variation is an difficulty in designing reliable CMOS mixed signal systems with high yield. To minimize the variation in voltage gain due to variations in process, supply voltage, and temperature for common trans conductance-based amplifiers, we present a new compensation method based on statistical feedback of process information. We further apply our scheme to two well known amplifier topologies in the sun-micron CMOS process as design examples—an inductive degenerated low-noise amplifier (LNA) and a common source amplifier (CSA). The proposed method improves the variation in S21 of an inductively degenerated cascade LNA from 8.75% to 1.27%, which is a …

We consider dynamic configuration of wireless sensor networks, where certain functions can be automatically assigned to nodes at any time of network operations, based on the parameters such as remaining energy and topology changes. In order to achieve the topological controlled network reconfiguration the received signal strength indication value along with battery level of nodes were used which indicate any changes in the network layout and remaining energy of the nodes. Based on these two parameters new tasks were then assigned …

Lna Integrates Fast Shutdown Function, Chin-Leong Lim

Chin-Leong Lim

To minimize dead time in time domain duplex (TDD) transceiver, reception should ideally commence as soon as transmission ends. However, the low noise amplifier (LNA), which is typically shutdown during transmission to prevent device damage and receiver overload, can exhibit a turn-on delay. In older implementations, the shutdown function is external to the LNA device. So, one way to reduce part count and to miniaturize this class of LNA is to integrate the LNA and shutdown function in a microwave monolithic integrated circuit (MMIC). The integration also allows the shutdown circuit to be connected to the LNA at an optimum …

Also, variation of output power with frequency was investigated by …

A Fast-Converging Mppt Technique For Photovoltaic System Under Fast Varying Solar Irradiation And Load Resistance, Saad Mekhilef

Saad Mekhilef

Under fast varying solar irradiation and load resistance, a fast-converging maximum power point tracking system is required to ensure the photovoltaic system response rapidly with minimum power losses. Traditionally, maximum power point locus was used to provide such a fast response. However, the algorithm requires extra control loop or intermittent disconnection of the PV module. Hence, this paper proposes a simpler fast-converging maximum power point tracking technique, which excludes the extra control loop and intermittent disconnection. In the proposed algorithm, the relationship between the load line and the I–V curve is used with trigonometry rule to obtain the fast response. …
