Based upon a generally sub-ode method, which is a direct and unified algebraic method for constructing more general form travelling wave solutions of nonlinear partial differential equations(PDEs) and implemented in a computer algebraic system, we consider the shallow long wave approximate equations(BK).New and more general form solutions are obtained, including kink-shaped solitons, bell-shaped solitons, singular solitons and periodic solutions. The properties of the new formal solitary wave solutions are shown by some figures. © (2013) Trans Tech Publications, Switzerland.

Considering its working stability, semi-closed loop control is usually used in Mid-range CNC machine tool, but Processing quality of the product is Seriously affected by wear, hot variant, screw error and backlash of machine driven system. In order to improving machining precision, reformation processing on closed -loop of Y axis in THWMZT-1B CNC milling machine is introduced, such as connecting and installing hardware, setting parameters and backlash compensating. Commissioning results have shown that repeated positioning accuracy got 0.01mm, pleased result was got. © Guolan and Yunzhong.

The management system of the double switching signals' design is to achieve the persistent light warning effect by switching to the other main signal automatically when the car's turning signal is broken. This self-bringing manage system will automatically record the specific location of the broken signal light, and will notice the conservator or the maintenance worker to keep in repair the signal light. Thus, this way can improve managerial effectiveness and shorten examining time. This design adopts single chip or logic control chip to realize automatic switch; and transfers signals between turning signals and main control system according to low voltage power line transmission technology or wireless transmission technology. Based on this, the system will keep working constantly, and facilitate conservators to find stoppages and solve them efficiently. © (2012) Trans Tech Publications, Switzerland.

An μ-A ammeter has been designed based on TLC7135 and Nrf24LE1. A built-in 2.4 GHz wireless transceiver has been embedded in the product for tracking measurement in the system for a long time, and it can be used as a wireless micro-ammeter sensor for sampling and measuring the data through the wireless communication network. The micro-current measurement principle has been analyzed and the hardware circuit has been designed in this work. The simulation of design scheme has been carried out with the Proteus software, the measurement error and measurement accuracy have been analyzed quantitatively. The difference between the simulation result and the true value is ± 1 LSB. The resolution of the ammeter is 1/20 000, same as that of 14 bit A/D converter and the current resolution at 20 μ A is 1 nA. The proposed micro-ammeter sensor can be used for current measurement of the semiconductor leakage or the standby machine.

Distance education is a field of education that focuses on the pedagogy, technology, and instructional system designs that aim to deliver education to students who are not physically "on site" in a traditional classroom or campus. It has been described as a process to create and provide access to learning when the source of information and the learners are separated by time and distance. This emerging technology is becoming widely used in universities and institutions around the globe. With the recent trend of technological advance, distance learning is becoming more recognized for its potential in providing individualized attention and communication with students internationally. © (2011) Trans Tech Publications.

In this study, we focus on the development of energy efficient and achievable load balancing mechanisms for wireless sensor networks. Due to resource constraint and tremendous amount of sensors, one possible way of achieving maximum lifetime of the network is applying data aggregation on sensor data. However, existing approaches introduce significant computation and control overheads that often not suitable for sensor networks applications. In view of this, we propose an in-network data aggregation scheme by exploiting the inherent spatial correlation of the sensed data. Each sensor multiplies its reading with a random coefficient and sends the product to the next hop to calculate a weighted sum of all the massage. Instead of receiving individual sensor readings, the sink will receive all weighted sum and restore the original data. By doing so, each node only performs one addition and one multiplication in order to compute one weighted sum and consume the same amount of energy. Simulation results demonstrate that the proposed scheme is efficient and outperforms existing schemes in terms of energy gain and network lifetime. © 2011 Asian Network for Scientific Information.

In this paper, we investigate the multiple attribute decision making problems for evaluating software quality with 2-tuple linguistic information. We extended the TOPSIS model to solve the evaluation problems of software quality with 2-tuple linguistic information. According to the traditional ideas of TOPSIS, the optimal alternative(s) is determined by calculating the shortest distance from the 2-tuple linguistic positive ideal solution (TLPIS) and on the other side the farthest distance of the 2-tuple linguistic negative ideal solution (TLNIS). It is based on the concept that the optimal alternative should have the shortest distance from the positive ideal solution and on the other side the farthest distance of the negative ideal solution. Finally, a numerical example for evaluating software quality with 2-tuple linguistic information is used to illustrate the applicability and effectiveness of the proposed model.
