The analysis was done and an algorithm was developed for calculating a route in the urban transport network. Based on the input data, this algorithm determines the capability to pass the given flow between two points during the time, not exceeding the given one, by calculating the travel time by alternative routes. The algorithm is based on the determination of the shortest path in the directed multigraph. The calculation results are given for different routes, obtained using the developed program.

Aerodynamic analysis is carried out using superimposition of uniform flow with doublet over a spinning sphere. Analytical solutions of the pressure distribution and lift force over the spinning sphere are obtained based on Kutta-Joukowski theorem with the assumption that flow field around the spinning sphere may not influence the synthesized flow. The theoretical aerodynamic analysis reveals that the lift force over the spinning sphere is directly proportional to circulation, which coincides with the experimental results of Bearman and Harvey. It is found that the lift force over the spinning sphere is less than the spinning circular cylinder. The tangential velocity component on the surface of the spinning sphere yields a cubic equation, which is having one real and two conjugate imaginary roots

The finite element analysis by ANSYS finite element software is carried out on the three kinds of concrete strength specimens to explore the influence of concrete strength on the size effect of reinforced concrete circular column confined by GFRP sheet under axial compression. The results show that with the increase of concrete strength, the size effect of reinforced concrete circular column confined by GFRP sheet will be significantly weakened.

Nowadays, in high data rate wireless communication systems, the power consumption of the baseband modems is significantly affected by the channel decoder complexity, especially when codes like LDPC are used. In this paper, we propose a new type of code called Trellis-based Quasi-Cyclic (TQC)-LDPC convolution code, which is a special case of photograph-based LDPC convolution codes. The proposed TQC-LDPC convolution code can be derived from any QC-LDPC block code by introducing trellis-based convolution dependency to the code. The main advantage of the proposed TQC-LDPC convolution code is that it allows reduced decoder complexity and input granularity (which is defined as the minimum number of input information bits the code requires to generate a codeword) while maintaining the same bit error-rate as the underlying QC-LDPC block code ensemble. We also propose two related power-efficient encoding methods to increase the code rate of the derived TQC-LDPC convolution code. The newly derived short constraint length TQC-LDPC convolution codes enable low complexity trellis-based decoders and one such decoder is proposed and described in this paper (namely, QC-Viterbi).

In our today’s world the communication without the fault can be required. In signal processing there are many filters can be achieved for the communications such as the digital filters, FIR filters and the parallel filters. For the kind of error fault detection the parallel filters must be suited for the high level applications. The parallel filters with fault tolerance have been proposed here to detect the multiple errors present in the communication channels. The error recovery could be done by using the hamming code and the extended hamming codes. The hamming code can be proposed for the single bit error tolerance and the extended hamming code can be achieved for the multiple bit error detection. The fault tolerance architecture having this error correction method can be very less power, area and the delay consumption. The parallel filter architecture with error correction must be suitable for the high stable communication with high reliability. The most required system for the applications may be considered for the single event test in the parallel architecture. The high secure communication with the multiple bit errors can also to be recognized from the channel length of the input signal. This architecture can be less latency with its high number of the latches. The on-data path pipelines for this process can be varied from the structure for the event based signals. These hamming codes with the error detection and correction for the single bit and the multiple bits can be achieved. The process variation and its implementation can be achieved by using the Xilinx ISE software. The power analysis can be done through the X power analyzer.

Regression analysis of the most common techniques in estimating labor productivity rates in Iraqi construction projects. In the first part of this research has been identified the factors and variables are affecting to the brickwork productivity and most important of these variables the age, experience, high building, the number of workers and security condition of the site. One model was built for the prediction the labor productivity rates for brickwork item. The data used in this model was collected from construction project in Iraq. It was found that Multiple Linear Regression (MLR) have the ability to predict the construction productivity for brickworks with a good degree of accuracy of the coefficient of correlation (R) was 87.28%,and average accuracy percentage of 92.5%.In the second part of this research was development another mathematical model for the same variables using Logistic Regression Technique (LRT). Results of the study showed that the use of a binary logistic regression gave a logical response results are consistent with the studied casewith a moderate degree of average accuracy percentage of 95.8%.the application of Logistic Regression Technique, as a modern technique, in Iraqi construction project is necessary to ensure successful management, and many of the planners feel the need of such system in planning stage of construction project. Based on the foregoing, the study recommends expanding the use of logistic regression to estimate productivity.

Costruction management should be able to know some ways to measure workers productivity before making an effort to improve productivity. Productivity is one of the most important issues in both developed and developing building construction. The research objective were to analyze labor productivity by using work sampling method, It is used to obtain Labor Utilization Rate (LUR) value. The LUR analysis results of formwork, reinforcement, and concreting are 47.32%, 43.17%, and 49.76%. Total LUR of three work type is 45.60%. It is can concluded that the productivity is still relatively high.

The study aims to solve the universality of evolutionary computation for solving different optimization problems, avoid the repeating design, and share codes, so as to improve the application efficiency of the algorithms. To achieve this, the authors put forward a general evolutionary model based on object-oriented programming language (C# language) in this paper. This model divides the problem domain, the fitness function, the algorithm and the parameter control into different classes, which are encapsulated into different objects so as to enhance the independence of each module. By utilizing the model, it is convenient to develop, reuse, extend and modify software while guaranteeing the universality of the algorithm at the same time.

Seismic damage showed that the effect of earthquake damages on urban lifeline system is much larger than other disasters. Shell element model of four nodes was used to simulate the buried pipeline, and the interaction between soil and pipeline was simulated by nonlinear soil spring, seismic response of buried variable-diameter pipeline under strike slip fault was analyzed by using finite element software ADINA. Through studying the influence of concentric and eccentric variable-diameter on seismic response of pipeline, the conclusion was obtained that seismic capacity of concentric variable-diameter pipeline is better than that of eccentric variable-diameter. The results of research provide a certain guiding for the seismic design of buried variable-diameter pipeline across the fault.

With the decreasing of energy around the world， The significance of energy-saving insulation in industrial and agricultural production and civil life become increasingly prominent. In order to reduce the heat loss of pipeline, and raise the utilization rate of heat energy, a number of scholars have carried out research on thermal insulation materials and their properties. Heat preservation measures must be taken to reduce the heat transfer from the internal heat source to the outside of the pipeline. Obviously, the main purpose is to reduce the heat loss, saving electric energy or fuel. Through the analysis of the current situation of domestic and foreign pipeline insulation, the performance of the main insulation materials were reviewed.

The medical field is experiencing setbacks, medical cases almost always seems to outnumber the number of medical experts required to attend to them. This in part is due to lack of qualified doctors to handle specialize cases. Inefficient medical expert to diagnose and properly treat typhoid fever has significantly increased mortality and morbidity rate in both infant and adult resulting from the ailment. The objective of this project therefore is to Design a Rule-Based Expert System that will offer proper diagnosis and prescribe appropriate medication for patients. The shell of the Expert System developed in this project uses the Forward Chaining Inference Algorithm (Mechanism), a technique that has been neglected by many expert system developers in the medical field. Oral and written interview was adopted to acquire knowledge from experts in the domain and get insight into the required information needed for the development of the system. Java programming language and its related technology were used in the development of the system based on its functionality of platform independence. We employed Derby's database engine for our database design.
