To successfully move a robot into the building, the elevator button and elevator floor number detection and recognition can play an important role. It can help a robot move in the building, just as it also can help a visually impaired person who wants to move another floor in the building. Due to vision-based approach, the difference in lighting condition and the complex background are the main obstacles...
In a computer vision system, handwritten digits recognition is a complex task that is central to a variety of emerging applications. It has been widely used by machine learning and computer vision researchers for implementing practical applications like computerized bank check numbers reading. In this study, we implemented a multi-layer fully connected neural network with one hidden layer for handwritten...
Bluetooth 5.0 is revolutionizing the Internet of Things (IoT), allowing design engineers to pioneer innovative solutions while advancing the field of design engineering itself. With up to 4 times the range, 2 times the speed, 8 times the broadcasting message capacity, and improved coexistence with other cellular and wireless technologies, the enhancements of Bluetooth 5 open more possibilities than...
Various clustering protocols for ad hoc networks have been proposed in order to optimise the networks energy efficiency. These protocols rely on the formation of highly dense clusters which resulted in a large variation of cluster size and thus suffers from a poor load balancing. This paper introduce a novel distributed clustering algorithm using fuzzy logic for the formation of uniform size clusters...
Flash floods can be regarded as an apical natural hazard in many countries that eminently affect the safety of the human lives, precious belongings, livestock and agricultural farming land. Variety of techniques like engineering (construction of dams and reservoirs) and nonengineering (prior investigation of flash floods) has been advanced to forecast the run offs. An efficient disaster management...
This paper presents how highest and best use (HBU) concept can be applied for value-based decision making. HBU is a technique to analyze and select the best use of land to get maximum productivity. Analytical Hierarchy Process (AHP) is applied to develop process of decision making by determine the preferences and best fit option. The criteria are based on the concept of HBU which are legal, physical,...
Calcium carbonate is carbonic salt that is needed in the industry for varied applications. This work studies on gas diffusion as a method to synthesize CaCO3 nanoparticles at different temperature for reaction from 6h to 168h. Surface morphology and molecular bonding for the precipitated CaCO3 was studied. This was done by characterizing the precipitated CaCO3 by FESEM, EDX and FTIR. FESEM micrographs...
A rapid growth in the internet network technologies claims for a better routing protocol in transmitting data. The network performance is evaluated to compare the two Link State (LS) routing protocols which are the Open Shortest Path First version3 (OSPFv3) and Intermediate System to Intermediate System (IS-IS). The evaluation is done in terms of the performance in the network convergence through...
Array antenna has been utilized in many radio telescope systems, especially for low frequency transient observation, to increase their resolving power. In this paper, a new method to determine the maximum resolving power of an array radio telescope based on the single antenna beamwidth is proposed. The method is derived from theoretical calculations combined with simulations. Statistical result shows...
Wireless power transfer based on electromagnetic coupling is a popular technique that use in cases where connection between wires are troublesome or inconvenient. Recently, it has been drawing a lot of researcher attention. This is because the usage of portable mobile device is increased and there is a need for wireless charging as their power source. In this paper, an approximate LC lumped element...
A unique hook-shaped conformal metal strip has been used to excite a cylindrical multilayer dielectric resonator antenna (DRA). By using the proposed unique feed and multi dielectric layers, a broadband circular polarization have been achieved over a bandwidth of ∼9.8% in conjunction with an impedance-matching bandwidth of ∼12.8% at same frequency range. The DRA has been successfully designed and...
Renewable energy is the future of energy generation. As wind turbine is big part of this energy revolution, research of its impact to current electrical power grid is of paramount importance. Wind speed varies periodically and geographically. This variability of wind power generation needs to be compensated by the conventional generators. In doing so, the temperature of the generators increased in...
Rf substrate biasing method was observed to succeed in controlling the transition temperature (Timt) while maintaining of almost two-order of magnitude transition in resistance changes, and also the hysteresis loops, indicating the intrinsic IMT properties of VO2 films. The lowest Tt of 36°C was achieved in the film deposited at 40 W. Asymmetrical XRD measurements revealed modifications of the aM/2...
The green-house effect has been a major concern for all researchers and big company world-wide. This study reduces the power consumption of single server without degrading the quality of the service by focusing on minimizing the migration of Virtual Machine. Existing migration system for Virtual Machine does not perform well for kinds of load toward single server. Thus, a new algorithm is calculated...
A photonic bio-recognition system has the potential to be used with the advancement in a biosensor development. The system requires an optical sensing system, microfluidic device and biological reagent for microorganism detection. Although, biosensors are available in the market, a label free and a lab-on-chip approach will be a flexible solution. The main objective of this work is to develop photonic...
A circularly polarized (CP) hollow hemispherical dielectric resonator antenna (DRA) is presented. The CP DRA that is excited using conformal open half loop metal strips has been studied theoretically and experimentally. The proposed antenna configuration has provided a measured CP and return loss bandwidths of ∼11.i5%, and 10.32% respectively. The DRA has been simulated using Method of Moments (MoM)...
There are more and more vehicles on the road in every country, which have to be parked in spaces that are becoming increasingly packed. This is a big challenge especially for city planners, architects, and building owners. To meet this demand, the innovative and space saving-parking system is created. This is the new way of technology that can be applied to all users and it is more efficient than...
Depletion in Malaysia's fossil fuels has caused the country to explore other potential energy source. Of all possible options, nuclear power has been considered the best. However, the plan for its implementation has been met with many challenges primarily within the issue of acceptance among public. This paper explores challenges of implementing nuclear power in Malaysia. Data were obtained through...
