In this paper, a novel miniaturized capacitive loaded electromagnetic band gap (EBG) has been developed with the patch size of approximately)./36. The dimension is controllable using the lumped capacitive elements values. The surface impedance characteristic of the EBG structure is switchable as pin vias have been inserted and removed within the EBG center and the ground plane. Switching the EBG surface...
In this paper, we have studied and surveyed the field of robotic hand and the works that have been done in this area related to types of materials such as piezoresistive, piezoelectric and capacitive as well as a few types of pressure sensors. It indicates that piezoresistive pressure sensor is the best technique that can be used to implement a robotic hand for pick and place application. An adequate...
In order to maintain the viability of probiotic, the used of prebiotic is important. Aloe vera has been hypothesized to be a prebiotic potential for probiotic. Due to low viability of encapsulated cells, Aloe vera gel was used to be part of enacapsulating matrices for probioctic, Lactobacillus acidophilus. As a result, optimization of Aloe vera gel with sodium alginate was carried out in order to...
The aim of this research was to optimize the cultivation medium for economic production of a probiotic bacterium, Lactobacillus acidophilus using Aloe vera medium with different carbon (glucose, fructose and sucrose) and nitrogen (yeast extract, meat peptone, ammonium sulphate and urea) sources. Screening step was performed using 28 1/16 fractional factorial design (FFD) to investigate the significant...
In this paper, an experimental procedure for designing a novel 5.8 GHz triangular microstrip loop resonator antenna is presented. The proposed antenna is fed by a microstrip feed line arrangement and excited by a coaxial feed probe. The antenna elements were rotated 90 degree clockwise about the z-axis in parallel with the microstrip feed. This was done in order to ensure a good proximity coupling...
Cluster based routing technique is most popular routing technique in Wireless Sensor Networks (WSNs). Due to varying need of WSN applications efficient energy utilization in routing protocols is still a potential area of research. In this research work we introduced a new energy efficient cluster based routing technique. In this technique we tried to overcome the problem of coverage hole and energy...
Nowadays, utilitarian value might be cheap and practical but people usually interested in a little aesthetical too, thus automatically creates a new concept of environment in order to appreciate creativities. This innovation is an attempt to introduce a fresh concept to the environmental art by combining few elements of art with a modern concept design using ceramic materials. The objective of this...
We evaluate the power savings achievable in the design of optical core networks considering design alternatives to solve LTD and RWA problems. Results show that an appropriate design can increase energy efficiency in WDM networks.
Falls are a major problem in older adults worldwide with an estimated 30% of elderly adults over 65 years of age falling each year. Timely detection of medical emergencies can reduce treatment latency and significantly improve healthcare services. This paper presents the design and implementation of a fall detection system using compressive sensing. The proposed system is built around Shimmer technology...
Thermophiles are microorganisms that inhabit at extremely high temperature environment. Thermoenzymes from thermophilic microorganisms are heat-stable, able to withstand denaturants of extremely acidic and alkaline conditions, and thus, have a considerable potential for many industrial applications. The aim of this study was to isolate and characterize cellulolytic thermophiles. Five isolates of cellulase...
Salat is a formal prayer practice by all Muslims. When performing salat, it involves with several movements namely standing, takbeer, bowing, prostration and sitting. The study was to quantify and compares the muscle activity (surface electromyographic signal) during Salat and stretching exercise. Three main movements in Salat (takbeer, bowing and prostration) and similar stretching exercises to the...
Arabic is widely considered as one of the most difficult languages which made up of phoneme-based and has its own category. In that regard, determining its speech quality is a big challenge. The letters that particularly found difficulties are the emphatics and many speakers do find articulating these letters as a challenge. The emphatic consonants are *** (sad), *** (Dhad), *** (Taa'), *** (Dzo)...
The Large Angle Beamstrahlung Monitor measures the intensity, spectrum and polarization of light emitted in the beam-beam interaction, which are related to beam-beam interaction parameters. The hopes for this device are that the study of the beam-beam interaction can change from being mostly model-driven to being mostly data-driven. High precision is certainly desirable, and a 0.3% relative precision...
In this paper, we propose a new design of Fiber-to-the-Home (FTTH) network based on Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA). The FTTH network based on SAC-OCDMA system is tested by employing the Dynamic Cyclic Shift (DCS) code. Whereas, the DCS code is selected due to reduced and mitigates the effect of Multi Access Interference (MAI) in comparing with existing...
Two different locations of Erbium Doped Fiber (EDF) in dual ring configuration to generate double frequency shifted of multiwavelength Brillouin Erbium fiber laser (BEFL) have been investigated. The experimental results show that the location of EDF has important roles to determine the number of output Stoke signals and tuning range. Beside the Erbium gain, the Brillouin gain also contributes to the...
By using different fiber types as gain medium such as 500 m HNLF, 215 cm Bi-EDF, 7.2 km DCF, 11 km DCF, 18.2 km DCF, as well as the composition of Bi-EDF with 11 km DCF and finally the composition of Bi-EDF with the 18.2 km DCF, Raman gain was characterized and measured by the same set up as proposed in our study. The results revealed that the composition of Bi-EDF with the 18.2 km DCF provided the...
This paper reports on the effects of nanofiller on the puncture resistance of high strength coated woven fabric. High strength Kevlar woven fabric was coated with natural rubber latex (NRL) and carbon nanotube (CNT) (1 phr, 3 phr, 5 phr) filled NRL. The coated fabrics were tested for puncture resistance test and the results were compared with neat fabrics. Three puncture probes with different geometry...
Thermophiles are microorganisms that inhabit at extremely high temperature environment.
