This paper presents the analysis of modeling for artificial lateral line flow sensor. An artificial hair cell sensor is the current technology that based on a biological inspiration and widely used in underwater applications including glider, robotic and autonomous surface vehicle (ASV). The structure of the lateral line flow sensor is consisting of cantilever beam and four hair cells attached perpendicular...
In this paper an analytical model of emitter saturation current of a silicon solar cell has been developed to show the effects of field dependent carrier mobility and of both doping dependent SRH and Auger recombination mechanisms in a non-uniformly doped emitter. In developing this model the doping dependency of carrier lifetime as well as the bandgap narrowing effect due to heavy emitter doping...
Extended Euclid Algorithm (EEA) is one of the alternatives in gaining the multiplicative inverse value in finite field GF(28). Previously, the look-up table (LUT) approach is widely used for this purpose, especially in hardware cryptographic implementations. In this paper, the EEA method is used to build the multiplicative inverse value generator as an alternative of the commonly used LUT method....
In this paper, the Mel-Frequency Cepstral Coefficient (MFCC) is demonstrated as an effective feature representation method for spoken letters recognition. The Multi-Layer Perceptron (MLP) was used as a classifier to discriminate between two spoken letters - ‘A’ and ‘S’. The dataset consists of 72 samples (35 and 37 samples of spoken letters ‘A’ and ‘S’, respectively). The samples were represented...
Simple stochastic model is normally used in GPS positioning by making assumption that all GPS observables are statistical independent and of the same quality. By the above assumption, similar variance is assigned indiscriminately to all of the measurements. A more detail stochastic model considering specific effects affecting each observable individually may be approached such as the ionospheric effect...
As embedded applications have became more complex, design of embedded processors has created a research area for low power and yet high performance architectures. Power consumption is as important as performance in battery-powered embedded systems and in future, embedded processors are to process more computation-intensive applications with limited power budgets. Therefore, power consumption of theses...
Operating multiple mobile robots while having finite amount of energy is one of limitation on doing a task in long term. In this work, a decentralized controller system based on inspired of swarm honeybees in foraging food's behavior has been developed and applied on the mobile robot. This system is simulated in Player/Stage. The algorithm is divided by working robot and foraging robot. The change...
This work presents the attempt to design and develop a wind direction sensor base on temperature change by wind. Array of LM 35 temperature sensor with H/W has been used to indicate the wind direction. The proposed array is used on robot vehicle as the initial stage of plume tracking activity. The robot uses casting movement in form of zigzag motion to reach the wind source. In addition to tracking,...
The market for wireless sensor networks (WSNs) is rapidly growing, yet limited by batteries with short lifetimes. Providing a green, virtually infinite alternative power source to traditional energy sources will significantly expand the applications for WSNs and other technologies. The use of piezoelectric materials to capitalize on the ambient vibrations surrounding a system is a method that presents...
This paper presents an interesting approach known as “activity-based modeling (ABM)” for scheduling activities or operations in discrete-event based dynamic systems (DEDS). In this paper, firstly, ABM is introduced. Secondly, a new tool is known as GPenSIM is introduced; GPenSIM is developed for modeling and simulation of DEDS using the activity-based modeling approach; GPenSIM is based on Petri Nets...
Markov Chain Monte Carlo (MCMC) is one of the algorithms that have been widely implemented in tracking vehicle for traffic surveillance purposes. The sampling efficiency of the algorithm is essential to determine the vehicle position accurately. However, the sample size of the algorithm is still remaining an issue as non-optimal sample size will defect the tracking accuracy, especially when the moving...
A fire detector circuit kept in home triggers the landline telephone to dial automatically the alternative cellular phone of the resident. If he is inside the home, this alarm alerts him to operate the fire extinguisher manually. If he is away he dials back to the home telephone number with an additional digit to trigger ON the fire extinguisher. By dialing further digits he can switch off selected...
