The Linguistic Analysis of Sound Ambiguity and Meaning Ambiguity
Статья научная
This thesis will talk about ambiguity by classifying it into sound ambiguity and meaning ambiguity. In the first part, the author will discuss the theories in ambiguity namely the Q-and R-principle and IC-analysis which are the most basic and important in the analysis of ambiguity. In the following part, the author will analyze the sound ambiguity and meaning ambiguity in detail. Polysemy and homonymy are the main causes of sound ambiguity. Culture and context are the main causes of meaning ambiguity. And in the last part the author will discuss the advantage and disadvantage of ambiguity. Ambiguity can be seen as a sword that has two blades. The positive side should be studied to make the language becomes more interesting and vivid. The negative side should be avoided to make the writing or speech more accurate.

The Navigation Risk Assessment Using Wavelet Neural Network
Статья научная
Factors that influence the security of navigation have the characteristics of dynamics, randomness, uncertainty and mutual influence, so the system of navigation security is a typical non-linear system. Due to the limitations of traditional mathematical methods solving the non-linear system, this article combines artificial neural network model and wavelet analysis to construct the wavelet neural network model for the navigation risk assessment, and puts forward the index system, weights calculation and algorithm with examples. Results shows that the wavelet neural network model for evaluating can be solved the defects such as subjective arbitrariness and the fuzzy of conclusions existing in traditional evaluation methods, and it can do better than the common artificial neural networks in fitting accuracy and convergence rate, so the application of wavelet neural network model has an important value.

The Research of the Structure and Permission of Workflow Based on AOP
Статья научная
After analyzing the basic concept and method of Aspect Oriented Programming (AOP), the method based on AOP was presented to solved the security validate, permissions verification, log and so on. Compared to the conventional Object Oriented (OO) approach, AOP technology could avoid such problems as tangled code and scattered code, and had obvious advantages in raising the component reusability, optimizing processes and reducing the system complexity. Finally, an integration example of permissions verification in workflow system was provided, and the implement based on AOP was provided too.

The Synthesis of Sparse Antenna Array Based on Improved Mind Evolution Algorithm
Статья научная
Mind Evolution Algorithm (MEA) imitates the human mind evolution by using similartaxis and dissimilation operations, which overcomes the prematurity and improves searching efficiency. But the generation of the initial population is blind and the addition of naturally washed out temporary subpopulations is random. This paper improved MEA by introducing chaos and difference into it and proposed Chaos Difference Mind Evolution Algorithm (CDMEA), which brought adequate diversity to the initial population and saved the excellent genes in the evolution. Then CDMEA is used in the synthesis of sparse antenna arrays. The excellent results confirmed the effectiveness, flexibility and suitability of CDMEA.

Bangladesh has been using fossil fuel sources for the last years to generate electricity. The electricity power generation capacity of Bangladesh must enlarge to support the increasing electricity demand nowadays. As the conventional fuel resources are limited on the earth, renewable resources (ex: PV, wind) must be used in the future. The aim of this study is to design a hybrid electricity and hydrogen production system with the photovoltaic, wind turbine, hydro, diesel generator, electrolyzer, and reformer using Hybrid Optimization Model for Electric Renewable (HOMER) software under the study area Delduar, Tangail, Bangladesh (2408.5/N, 89054.1/E). This research focuses on maximum electricity generation using renewable energy sources with a minimum cost of energy (COE). According to the Homer optimization model, the levelized cost of energy (COE) based on a PV-wind-hydro-diesel generator-electrolyzer-reformer-battery hybrid electricity generation system is $0.281, the net present cost is $3.22 million, and operating cost $60,401 with 99.5% renewable fraction respectively. Furthermore, the analysis confirms that hybrid PV-wind-hydro-diesel generator-hydrogen power plant construction in Delduar, Tangail area is economically feasible.
