Based on the research on development situation of college English teaching in computer network environment, the essential task of the thesis is to explore the ecological teaching model. In this paper, the author focuses on presenting the overall design process of empirical research undertaken in the paper. Specific arrangements of the structure are as follows: firstly, to define the research questions and select proper research subjects, variables and research methods, then to list the design process and specific steps in great details. Finally to make a classified study and ecological analysis based on the collected data and textual information. Copyright © 2017 American Scientific Publishers.

In the article, three kinds of swarm intelligence optimization algorithm are discussed including the ant colony optimization (ACO) algorithm, the particle swarm optimization (PSO) algorithm and the shuffled frog leaping algorithm (SFLA). The principle, development and application of each algorithm is introduced. Finally, an example of TSP is used to test the performance of ACO. © (2013) Trans Tech Publications, Switzerland.

The paper exposits the purpose and the significance of the wind jig dry coal preparation technology, discuss the working principle and control methods of the wind jig dry coal preparation system. Based on the dynamic data of the physical density, the control system auto tunes the speed of the opening by utilization of a frequency governor. Therefore, it controls the thickness of the beddepth very precisely and achieves the close loop control in the dry preparation system of coal dressing. Make use of adjustable air pressure and mechanical vibrations of materials according to the density and the particles on the sorting bed for loosing and layered, and using adjustable nesting institutions coal particles of different densities to classify, in order to achieve separation, refuse dumping, desulfurization purposes. © (2011) Trans Tech Publications, Switzerland.

A chaotic digital watermarking scheme based on logistic mapping is tested by experiments. Being of human visual system(HVS) masking properties, the watermarking adapt itself into the image, which ensure the watermark is invisible. Experimental results show that the proposed algorithm has good robustness for the common signal distortion (adding salt & pepper noise, median filtering, etc.) and geometric distortion (lossy compression, shear, etc). © (2011) Trans Tech Publications, Switzerland.

In this paper, we propose an algorithm for cluster generating and service discovery based on service popularity in wireless community network, which makes full use of the imbalance of the service request in the network, leading to that the requests could be replied quickly in shorter time. At the same time, the algorithm could adapt well to the wireless environment and incur less update information when the topology is changed. According to the simulation in the OMNET++, our algorithm performs better than the flooding and CRP in several aspects. © (2013) Trans Tech Publications, Switzerland.

Remote education is a new type of education mode in comparison with the conventional face-to-face education. It enables the teacher to teach students at remote sites by live broadcasting the teaching course over the network, but students usually participate in the course with the need of collaboratively referring and operating the 3D geometric models of educational objects in the live video scene of real environment. Augmented Reality (AR) technology has the potential to overcome these deficiencies and enable more natural communication between teacher and students. This paper surveys the functions of AR in education and describes a shared AR environment for remote education (ARERE) to build a typical AR-based remote education system, which overlays computer generated educational information on the live video scene of real education locale and shares the augmented video scene among all participant students, providing the opportunity for students to interactively and collaboratively participate in the AR-based study environment. The potential of ARERE is illustrated through a simulation scenario and the results prove that it yields superior quality compared to the traditional form of remote education. © 2010 IEEE.

Rare earth laurate composite thermal stabilizers for rigid PVC were prepared from lanthanum (cerium/neodymium) laurate, calcium stearate and pentaerythritol respectively. Influence of these stabilizers on PVC was determined by means of Congo red testing method, torque rheometer process tests and dynamic mechanics spectrometer. Thermal stability mechanism was discussed preliminarily by infrared spectrum. The result showed that the best ratio of composite was confirmed as follow: Lanthanum (cerium/neodymium) laurate: calcium stearate:pentaerythritol was 3:1:1. The rare earth laurate compound thermal stabilizers had good thermal stability. Static and dynamic thermal stability time could reach about 90 and 50 min. Processing performance and mechanical property were similar to those of lead salt system, while elongation at break was significantly higher.

The Access Grid (AG) targets an advanced collaboration environment, with which multi-party group of people from remote sites can collaborate over high-performance networks. However, current AG still employs VIC (Video Conferencing Tool) to offer only pure video for remote communication, while most AG users expect to collaboratively refer and manipulate the 3D geometric models of grid services' results in live videos of AG session. Augmented Reality (AR) technique can overcome the deficiencies with its characteristics of combining virtual and real, real-time interaction and 3D registration, so it is necessary for AG to utilize AR to better assist the advanced collaboration environment. This paper introduces an effort to augment the AG by adding support for AR capability, which is encapsulated in the node service infrastructure, named as Augmented Reality Service (ARS). The ARS can merge the 3D geometric models of grid services' results and real video scene of AG into one AR environment, and provide the opportunity for distributed AG users to interactively and collaboratively participate in the AR environment with better experience. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

The article introduces a high efficiency heating element of the air heater used in the industrial machine area, which can be used for high power low volume high efficiency air heater. The traditional air heater normally use tubular heating element or nickel-chrome alloy resistive wire wrapped around the mica rack as the heating element. Due to the constraint of the surface load, the power cannot meet the requirement of the industrial machine practice. Meanwhile, the movable air heater has special requirement for the volume and the power. Secondly, the metal sleeve heat resistance wire cannot release heat in the short period, and the life span at high temperature is relative short, this also restraint the heating temperature. The energy loss is quite significant due to the longer heating period. The higher power industrial air heater can effectively solve all the above mentioned problems. © (2012) Trans Tech Publications, Switzerland.
