The Finite-Precision Numerical Effects Analysis of Infinite Impulse Response

Ganbaatar Nandintsetseg, Xiang-E Sun
This paper mainly uses the MATLAB software to design IIR digital filter with the amplitude frequency characteristic method and zero-pole method, and then analyzes the effect of coefficient quantization and quantization effects in IIR digital filter arithmetic. It is that we can use the software to draw some pictures. These pictures can show coefficient sys

Graphical User Interface Design of FIR Filter

Myagmardorj Bayasgalan, Xiang-E Sun
FIR digital filter is a stable linear phase filter. Relying on the powerful computing power of MATLAB software and its GUI platform, this graduation project has completed the GUI design and implementation of FIR digital filter through programming. Through the FIR filter to achieve the program, you can design and implement a variety of amplitude characteristics of the FIR digital filter, accord

Bi Supra Transitive and Semi Minimal Systems

Taha H. Jasim, Mohammed Nokhas Murad
In the present paper, we define and introduce some new class of topological transitive maps called topological semi-transitive, bi-supra transitive maps, semi-minimal systems and study some of its properties. The main results are the following propositions: Every semi-minimal map is a minimal map, but the converse is not necessarily true and every bi-supra transitive map is transitive map.

An Agent Based Model to Analyze the Effects of Traffic Signal Timing on Vehicle Throughput in Inclement Weather

Michael Duff, Robert D. McLeod
This preliminary paper discusses the creation of an agent based model for a signalized traffic intersection derived from a previously developed mathematical vehicle-following micro-simulation model. The results of the agent based model are compared to the results from the mathematical model for verification purposes. The agent based model is then used to show the effects of inclement weather on vehicle throughput at a traffic inte

Pedestrian Detection with Improved LBP and Hog Algorithm

Wei Zhou, Suyun Luo
This article aims to improve the HOG SVM pedestrian detection method proposed by previous researchers. The speed of HOG SVM to detect pedestrians is relatively slow, and the detection accuracy is not very good. This paper proposes a PCA (principal component analysis) dimension reduction for HOG and also interpolates it. The article combines the dimensions of individual HOG features and improves th

Automatic Irrigation System Using Android

Souvanxay Lorvanleuang, Yandong Zhao
Laos is an agricultural based country. As agriculture is the main source of food for any country, it is important to have a proper irrigation system. This paper shows a design of automatic irrigation system based on android application using Raspberry Pi microcontroller, soil moisture and temperature sensor to help a famer to control and monitor a farm. This work facilitates the farm irrigation by switching the pump motor ON/OFF t

Comparison of Mathematical Methods to Obtain Concentration and Temperature of Newtonian Fluids in Tubular Reactors

Diego Alves de Miranda, Renato Cristofolini, Emerson José Corazza, Gilson Joao dos Santos, Claiton Emilio do Amaral
In several areas of engineering, it is possible to put real problems in mathematical functions; when we represent a problem with variables in the form of function, we were able to extract various information from it. This paper compared two different mathematical methods, being the finite difference method and the Fourth Order Range-Kutta method, to analyze the concentration and temperature of

Computer Aided System for Crankshafts Failure Rate of Automobile Based on Distance Travel and Age

Yakubu Anakobe Jimoh, Buliaminu Kareem, Akinnuli Basil Olufemi
The crankshaft is the part of an engine which translates reciprocating linear piston motion into rotation. Automobile crankshaft failure, apart from poor maintenance culture, is caused by age and distance covered. These attributes which caused crankshaft failure were investigated using questionnaire administration and oral interviews of the maintenance expert and experienced personnel in the three selected

Harmonic Paradigm

Yoosef Habibi
Programming paradigms are a way to classify programming languages according to the style of computer programming [1]. In this paper, we tried to present a new programming paradigm by interweaving the concepts of harmony and an inspiring sample of nature (jellyfish and its way of life). This model includes some of the advantages of available paradigms such as object-oriented and functional paradigm as well.

On Comparative Study for Two Diversified Educational Methodologies Associated with “How to Teach Children Reading Arabic Language?” (Neural Networks’ Approach)

Hassan M. H. Mustafa, Fadhel Ben Tourkia
This paper considered the increasingly sophisticated role of artificial neural networks (ANNs) after its applications at the interdisciplinary discipline incorporating neuroscience, education, and cognitive sciences. Recently, those applications have resulted in some interesting findings which recognized and adopted by neurological, educational, in addition to linguistic researchers. Accordingly,ANNmodels vary in relation to the n
