With the increase of emergency incidents, emergency logistics development is particularly necessary. Based on the analysis of literatures, this paper pointed out the current shortcomings of China's emergency logistics development. Furthermore, It proposed several practical suggestions on how to improve the emergency logistic system of China, which includes that we should improve the emergency response...
This paper investigated the relationship between capital structure and corporate performance. Differing from former studies, the paper stood on a special position of small and medium-sized enterprises and evaluated corporate performance by factor analysis method. Based on 608 observations, conclusions show that capital structure can improve corporate performance for small and medium-sized enterprises...
Data Envelopment Analysis (DEA) is a linear programming methodology to measure the efficiency of multiple decision-making units (DMUs) when the production process presents a structure of multiple inputs and outputs. It excludes the subjective factors and has been applied in many areas. This paper is mainly focused on the input-output efficiency appraisal of key industries of Hebei province based on...
Polyaniline/graphene nanocomposite (PANI/G) was synthesized by an in situ polymerization procedure. The microstructure of PANI/G was characterized to be a mixture of PANI nanowires and graphene sheets by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Energy Dispersive X-Ray Fluoresence Spectrometer (EDX). PANI/G was used to modify glassy carbon electrodes to detect...
In China, the development of economy and improvement of living level make people pay more attention to their indoor air quality, especially in their living room where they stay much more time than in other places. It is also a common idea that indoor air quality can have big influence on people's health, work productivity and so on. In order to get some information of different counties of Asia and...
Shear strength of granulated rubber and loess mixtures were investigated through direct shear test to evaluate the possibilities of the used tire as a lightweight fill material in geotechnical engineering. Test results indicated that the shear strength increased dramatically, at the content range of approximately 30%, higher than either pure granulated rubber aggregates or pure compacted loess. The...
In recent years, people begin to pay more attention to the efficiency and low cost of operation of manufacturing material department, and make each subsystem more perfect. This paper aims to study the optimal management of logistics system in manufacturing entreprise. Based on analysis of the current situation in the manufacturing enterprise's logistics management, this paper points out the existing...
Bombs are detected by different machines and mediums but all works only under the presences of experts. They will analyze the presence and type of bombs. But this way of analyzing takes long time. In this paper, A combination of wireless sensor network supported by an expert system is the crux of the detection mechanism. Surveillance is taken care by 24X7 round the clock with effective alarming systems...
Traditional Chinese Medicine (TCM) has received considerable attention due to addressing its the real cause of the illness while western medicine treats symptoms. However, the TCM hospitals can not satisfy all those ever-increasing requirements of medical care resources when people pay more and more attention to their health conditions. In this paper, a wireless sensor-networks-based TCM system for...
The auto semi-axle is the wheel direct driven part and important part of torque transmission, which is with wide variety and a great amount. In this paper, with taking the BJ-130 light semi-axle as example, the new characteristics of rotary forging process, the DW99-160 rotary forging machine and its working principle, blank forming of semi-axle, calculation of forging force and the selection of machine,...
Nowadays, Sensor network is extensively practical in numerous fields including general engineering, agriculture and environmental monitoring, health monitoring and surgery [1]. Sensors are designed as increasingly efficient and Miniature. As a matter of fact, the most important factor in the design of RF communications is the size of the antenna [2]. In fact, Miniaturization will be subject to steady...
The Quantified Constraint Satisfaction Problem(QCSP) is a generalization of the classical constraint satisfaction problem in which some variables can be universally quantified. This additional expressiveness can help model problems in which a subset of the variables take value assignments that are outside the control of the decision maker. Typical examples of such domains are game-playing, conformant...
The work principles, failure modes, material selection, heat treatment process of rotary forging dies are researched in this paper. When working, the dies not only bears great pressure and long time high temperature, but also bears alternating stress caused by repeated heating and cooling which can easily lead to heat fatigue crack. Selecting proper die material and using appropriate heat treatment...
The 21st century is the information age. Every university student should take possession of certain information capabilities. It is the basic level of university students. This paper sets forth the contents of the information capabilities, and explores the effective training ways.
This paper introduces a concept for a reliable and miniaturized power control unit (PCU). With this PCU, an electro-mechanical actuator (EMA) is controlled. This EMA is intended to be used in a swashplateless helicopter control system. As this is a safety relevant part of the helicopter, the PCU needs to work reliably under challenging ambient and operating conditions. At the same time, the whole...
This paper proposes a improvement of a common key block cipher, HyRAL[1], which has 128bits block length and supports key length of 128, 192, and256bits. It has a 4way generalized Feistel Structure of 24 rounds for 128bits key length, and 32 rounds for 192, 256, bits key length. The rounds are consists of G1,F2,F1,G2 functions which have 4-round Feistel structure to make the cryptanalysis hard. We...
Learning English is extremely popular in non-native English speaking countries, thus, the development of useful computer assisted learning programs and tools to support effective English learning are a critical issue in the educational field of learning the English-language. With the rapid growth of Internet technologies and easy access to information, the field of digital learning has stimulated...
Factors causing bottleneck shiftiness was studied in this paper, mainly in two kinds of factors, one kind of shiftiness causes is demand fluctuation and the other kind of reason is facility exception; In order to keep relative stability of the production system and reduce complexity of the production management, corresponding solutions were presented based on principles of the Theory of Constraints,...
Disaster assessment of the whole process of unconventional emergency is an important basis for relief. Unconventional emergency is dynamic and evolutionary which is concentrically embodied by difference information features and assessment objectives of each stage. Based on above, suitable assessment methods should be used. This paper studies on unconventional emergency information features and disaster...
Sufficient preparedness of emergency material is the key for a region to effectively response to sudden disaster. Therefore, it's necessary to give a comprehensive evaluation on its emergency material support capability for a region. Based on the evaluating indicator system of regional emergency material support capability, this paper using the G1 method, a kind of method needles to test its consistence,...
