Wireless sensor networks (WSNs) have serious resource limitations ranging from finite power supply, limited bandwidth for communication, limited processing speed, to limited memory and storage space. Data compression can help reduce memory and storage space requirements on sensor node. In WSNs, radio communication is the major consumer of energy. Therefore, applying data compression before transmission will significantly and directly help in reducing total power consumption of a sensor node thereby extending the network lifetime. In this article, we propose a simple lossless data compression algorithm designed specifically to be used by environmental monitoring sensor nodes for the compression of environmental data which are characterise by significant fluctuations in entropy. To verify the effectiveness of our proposed algorithm, we compare its compression performance with two existing WSNs compression algorithms using real-world environmental datasets. We show that our algorithm outperforms the other two algorithms when the entropy of the dataset is large. Copyright © 2013 Inderscience Enterprises Ltd.

Phytochemical based synthesis of palladium nanoparticles by bioreduction of medicinally potent plant extract Coleus amboinicus is investigated in the present study. Treatment of palladium chloride with Coleus amboinicus extract resulted in the formation of palladium nanoparticles. The formation of palladium nanoparticles were confirmed using UV-vis, FTIR, TEM and XRD. Polyols such as flavones, terpenoids and polysaccharides would be involved in bioreduction of metallic Pd (II) to Pd (0). The nanoparticles were spherical and triangular in shape with size ranging from 10-28 nm.

A simple and eco-friendly green synthesis of silver nanoparticles using Common duckweed (Lemna minor) as the reducing and stabilizing agent is reported. Lemna minor (Lm) extract was mixed with silver nitrate (AgNO3) solution for the production of silver nanoparticles (AgNPs). The reaction process was simple and the formation of highly stable silver nanoparticles at room temperature were observed. The morphology and crystalline phase of the Lm-AgNPs were determined using UV-Visible spectroscopy (UV-vis), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) spectra. TEM studies showed that the average particle size of silver nanoparticles were in the range of 10 to 20 nm. The antifungal activity of Lm-AgNPs against Aspergillus flavus was also investigated and showed that the synthesized Lm-AgNPs has a remarkable potential as an antifungal agent in treating fungal diseases. © RJPT All right reserved.

We examine numerically the uniaxially compressed stability of triaxially woven fabric (TWF) composites employing a proposed geometrically nonlinear finite composite plate element model with volume segmentation ABD constitutive relation, taking advantage of greatly reduced degrees of freedom. From satisfactory agreement with results from literature, numerous boundary conditions are explored for various aspect ratios in the buckling analysis. High dependencies of post-buckling patterns on plate aspect ratios are observed, from which a computationally time-saving characteristic equations have been defined before the occurrence of post-buckling state for practical convenience, best described on the basis of logarithmic critical buckling load and stiffness factor. These buckling characteristics have a direct general correlation to TWF's aspect ratios and boundary rigidities. © 2016 The Author(s).

First stage Xanthan recovery (cell and oil separation) from palm oil-based fermentation broth was carried out by hollow fibre microfiltration (MF) using Taguchi method as design of experiment (DOE) to study the effect of four main parameters on Xanthan recovery; transmembrane pressure (TMP), crossflow velocity (CFV), ionic strength (IS) and temperature (T). From S/N ratio larger-the-better analysis, optimum conditions for Xanthan recovery were at level 2 of TMP, IS and T respectively and level 1 for CFV whereas the significance of factor found by ANOVA was in the following order: IS > TMP > T > CFV. Confirmation experiment based on optimum condition yield 64 % Xanthan recovery. Particle size was influenced by intramolecular and intermolecular interactions of Xanthan's side chain under varying pH and cation concentration and affected the degree of Xanthan's transmembrane transport (XTT). Interpretation of zeta potential (ZP) elucidated XTT mechanism driven by surface charge modification of membrane surface due to cation binding. The formation of oily cake layer hindered most XTT, whereas better XTT achieved for zero-oil broth filtration.

The impact of environmental cleansing through inclusion of hazardous wastes in cement related products cannot be overemphasized. This paper presents outcomes of laboratory experiments on the utilizations of electric arc furnace steel slag and steel sludge (by-products from steel making industries) as cement replacements in concrete. Pozzolanic properties of steel slag and steel sludge were evaluated using pozzolanic activity test specified by ASTM C618. In addition, the materials were subjected to X-ray Fluorescence and X-ray Diffraction tests in order to identify their chemical as well as mineral compositions respectively. In the process, conductivity of materials suspension in calcium hydroxide (Ca(OH)2) solution were monitored. Mechanical properties of the concrete containing the steel slag and steel sludge were also evaluated. The results of pozzolanic activity tests show that steel sludge has a higher reactivity due its higher loss of conductivity which is about 72.9% as against 43.3% for steel slag. However, both materials show good reactivity in Ca(OH)2 solution. In fact, the strength activity index of both materials were observed to reach a minimum of 75% based on ASTM C618 requirement. Eventually, compressive strength development in concrete due to inclusion of 15% and 20% steel sludge and steel slag respectively yielded higher strength gains over the control mix particularly at later curing ages. © 2015 Elsevier Ltd.

This paper presents the breast cancer clinical decision support system prototype using our designed data mining techniques and modeling algorithms. We explore previous research works in this area and address the limitations in those systems vis-à-vis ours. Our system and algorithms can address those shortcomings and demonstrate its novelty in clinical comparative studies with real breast cancer patients. Key features of our demonstrator are the ability to predict survival rate (5 years post-diagnosis) of breast cancer patients, predict the tumor growth stage and estimate the survivability period (post-diagnosis) for the breast cancer patient. Our demo system could analyze the weightage influence of each breast cancer patient's medical variables. The demonstrator would provide similarity case reports with detailed histopathology medical conditions reports. The demo system would allow users to store, extract and edit the patients' database virtually and securely. Our demo system supports database and users' accounts confidentiality via secure user names and passwords logins. Copyright © 2016 American Scientific Publishers All rights reserved.

Malaysia exerts predominantly low wind due to its geographical location near to the equator. The monsoon winds are blocked by the Sumatra islands, and Borneo islands. Due to this wind technology is found be less efficeint and is not expected to be adopted for sustainable energy. With a average wind speed of 2-3m/s, along the east coast of west malaysia and small islands[1] the positioning of horizontal turbine is expected to do little work for the energy crisis across. However the sustainability relies much on the renewable and inadverently it is necessity to top up with alternate form. This paper proposes the vertical axis turbine and the novelty of levitation concept is introduced into the design. Its efficiency, cost and power output is more competitive than its counterpart. It is expected that with the use of the levitated turbine design wind as low as 1m/s can produce power, and the output potential of wind farms can be significantly increased. This type of wind setup does not require any significant land for installation, as its can be easily incorporated in rooftop, tower, and buildings. With Maglev VAWT the cost is significantly low with smaller size generator, lower weight, and low maintenance and long lasting. The design of such a maglev based turbine design to demonstrates the effectiveness of the proposed system is presented in this work. © 2012 IEEE.

Spiritual intelligence is an emerging term that is widely discussed and accepted as one of the main components that addresses and solves many life problems. Nonetheless there is no specific study being done to synthesize the spiritual intelligence themes from Western and Islamic philosophical perspectives. This research aimed to identify common spiritual intelligence themes from these two perspectives and elucidated its contents by the view of two well-known Islamic scholars; al-Ghazali and Hasan Langgulung. Seven spiritual intelligence themes were identified through thematic analysis; meaning/purpose of life, consciousness, transcendence, spiritual resources, self-determination, reflection-soul purification and spiritual coping with obstacles. These findings will be the groundwork for centered theory of spiritual intelligence themes that synthesize the Islamic and Western philosophical perspectives. It is hoped that this study will contribute significantly to the development of valid and reliable spiritual intelligence themes beyond the social and cultural boundaries.
