Abstract :

The outbreak and spread of diseases have been studied for many years. The ability to make predictions about diseases could enable scientists to evaluate inoculation/vaccination or isolation plans and may have a significant effect on the mortality rate of a particular epidemic. Therefore this research Modeling of Infectious Disease Through the Contact, Treatment And Recovery of Chicken Pox Patients (a case study of offa local government ) will study  how people  contact chickenpox and  investigate how many people an infected person can infect at a particular time and to develop model for male and female with Chicken pox . Regression analysis, Chi – square and R0 in SIR model were use to analyse the data. Result of the analysis revealed that the rate at which people contact chickenpox will be increasing and that contact of chickenpox is not depended on gender. Regression analysis shows that the model for male is  Y= 6,102 + 0.059X  and model for  female  is  Y= 5.177 + 0.078X  and both model   fitted the data. Further analysis revealed that, since R0 (Reproductive Number ) greater than 1 there will be likely epidemic on chickenpox  for male  and that 5.9% of the male that have chickenpox must be treated to avoid epidemics  and also 7.8% of the female that have chickenpox must be treated to avoid epidemics. We thereby recommend that health planner should educate people more on chickenpox and the preventive measures.

Abstract :

In this paper, a series of static water pitching attenuation tests were carried out on a small swath unmanned underwater SWATH-USV under different draft and different initial pitch angles. By changing the composition of the restoring moment and damping torque, 9 mathematical models of the system identification were established. By changing the composition of the restoring moment and damping moment, a systematic identification mathematical model for 9 modes of pitch attenuation motion was established. Based on the system identification theory and genetic algorithm, the system identification software was written in C# language. The experimental data of the unmanned craft were identified and analyzed, and a good mathematical model of the longitudinal pitch motion was obtained by identification and calculation, and the changes of the parameters of the identification parameters under different water and tilt angles are compared. The variation of each identification parameter at different draught and tilt angles was also compared. The relative error between the software forecast value and the test value shows that the prediction value is in good agreement with the test value, which proves the reliability of the system identification software, and can predict the future navigation and motion posture of the unmanned craft.

Abstract :

A simple index-guiding hexagonal-lattice photonic crystal fiber is presented in this paper for almost Zero Ultra Flattened Chromatic Dispersion with extremely low confinement loss. In this type of PCF, finite-difference time-domain (FDTD) method with the perfectly matched layers boundary conditions has been used.  The proposed holey fiber presents dispersion flattened optical fiber (DF-PCF) for tailoring near zero ultra-flatten dispersion of 0.58 ps /nm/km for 1.265 µm to 1.64 µm wide wavelength range or 375 nm flat band as well as low confinement losses of near 10-5 dB/km. By simulation result it is possible to achieve near zero ultra-flatten dispersion of 0.58 ps/nm/km for 1.265 µm to 1.64 µm with low confinement losses of the order less than 10-5 dB/km for second and third optical window which can be properly utilized in broadband optical transmission applications.

Abstract :

The levels of fundamental power generation from non-renewable resources such as coal, nuclear reactors are in less measure around world. Most of the power grids are based on non-renewable resources. The frame work and cost effective of such grids are more expensive. The economical level is increasing while increasing power generating ratios.So that we alter the method that is to generate the power from renewable resource such as forming solar (photo Voltaic) station. The system focused towards connecting the all energy resources like renewable as well as non- renewable sources and stores the energy. The energy distributed from the storage units to all distributed networks. The power generations of the grids are based on availability of resource. With respect to time, the total availability of resources is analyzed from each of the micro grids. The operation of  this system is based on BFO ((Bacterial Foraging Optimization))algorithm which verifies all the sources required for power generation as well as requirement of energy demand and priority will be given to the resource highly available with cost effective in to considerations.

Abstract :

Nonparametric regression is a type of regression analysis in which the predictor does not take a pre-determined form but is constructed according to information derived from the data. Kernel regression is a non-parametric technique, The objective of its is to find a non-linear relation between a pair of random variables X and Y. In this paper, explain the relation between exchange rate and trade balance in Egypt covering the period from 1985 to 2015. The determinant for the end of the period is a substantial change in exchange rates in Egypt due to the float of the Egyptian pound.

Abstract :

Vector Tracking Loop (VTL) is a recently proposed method to enhance GPS receiver performance. In VTL, a center navigation filter usually a Kalman filter (KF) is utilized to estimate navigation solutions and complete signal tracking together. Thus, all channels are processed together and mutual aiding can be obtained. Compared with Scalar Tracking Loop (STL), in which signal tracking is operated independently, researches have demonstrated that VTL performs better signal tracking performance. However, the nonlinear problems or the measurement outliers might affect the navigation filter and hinder VTL performance. This paper investigates applying robust adaptive cubature Kalman filter (AR-CKF) to VTL navigation filter. Robust M estimation is employed to resistant the measurement outliers and an adaptive factor is utilized to address the dynamic disturbance errors. A 3D dynamic trajectory is generated to test the AR-CKF based VTL. Simulations are implemented in a VTL software receiver, the results from comparing a common Kalman Filter with AR-CKF, which demonstrates that the employed AR-CKF improves VTL stability and accuracy.

Title : Effect of Macroporous Support Particles on Cell Immobilization, Mass Transfer and Rheology in a Stirred Cultivation of Aspergillus oryzae Using a Swingstir® Mixer

Abstract :

Immobilization of filamentous fungi via bioprocessing is a popular way to avoid mechanical damage to cells while increasing enzymatic activity. Passive immobilization is an efficient because chemical additives are not used during the immobilization process. In this study, passive immobilization of Aspergillus oryzae was performed in a stirred tank via a flexible agitator to improve the oxygen mass transfer and rheology while increasing the enzymatic activity. To elucidate the effect of porous biomass support particles on these factors, two particles with different sizes and populations were tested in separate batch cultivations. Results showed that one of the advantages of fungal immobilization is the prevention of a high rate of glucose consumption during a submerged fermentation process. Decreasing the size of the biomass support particle increased the shear-thinning behaviour of fluid. We also determined the optimal number of particles needed to produce the largest final amounts of immobilized biomass and enzyme activity.

Abstract :

The traffic light system has been working based on the specific signal light timing diagram, in wich, the time period for each lane is unchangeable. In some situation, the number of vehicles at each lane is much different, specifically, there are not any or so few vehicles at one lane, but there are so many vehicles at the others, and the time periods for all the lanes are still the same. This leads to many vehicles have to wait in unnecessary periods. In this paper, authors proposed a method to design a remote-control system for the traffic light which flexibly controls time periods through camera system. Raspberry-Pi, functions as the central process unit, both sends the image to Traffic Management Center and provides the traffic signals for traffic light system. This method is evaluated through the real experimental model.
