Space exploration missions have become increasingly complicated and various, and the current deep-space communication schemes can't meet the demand of high-speed and real-time multimedia correspondence. Therefore, the design of a fast and efficient transmission scheme is one of the important ways to solve the conflict. With organic combination of LDPC codes, continuous phase modulation (CPM) and turbo...
This paper presents a comparative study to examine the relationship between Enterprise Service Bus and Soft System Bus from the various aspects including motivation problems, ideas, purposes, goals, underlying principles, design methodologies, and architectures. Although enterprise service bus and soft system bus have a similar point, i.e. they are both for the components to communicate reliably,...
In recent years, field emission display (FED) has been attracting much attention in the science community [1, 2]. It is a key technology for FED to design an excellent cathode structure. Rational designs can decrease cost and simplify fabrication technology in the preparation process of the cathode. A field electron emitter with a novel self-focusing cathode has been proposed [3]. And it can be easily...
The data communication is becoming more and more rapidly and conveniently due to the information technology and Internet expeditious development. Therefore, the protections of information security and integrity are becoming very important in the network transmission. And the data hiding schemes are raised in the image research. The image data hiding technique is to embed secret message into a cover...
Inductively coupled plasma (ICP) has been widely used in semiconductor industry, due to its perfect characteristics of reduced ion damage, independently controllable ion energy and high density plasmas.1, 2 In the actual industrial processes such as etching process, to control ion energy and plasma density, two independent RF power sources are conventionally applied to ICP, i.e., the power source...
Defects such as dislocations and grain boundaries generally govern the efficiency of silicon-based solar cells. The use of a proper passivation layer can substantially increase the energy conversion efficiency. In this study, spot-like defects on the aluminum oxide passivation layer were observed. The formation and variation of spot-like defects were found to be affected by the thermal annealing temperature...
Sensitivity of soil erosion is the representative of the possibility of occurring soil erosion under natural conditions. Sensitivity evaluation of soil erosion is the reliable method to identify the highly sensitivity areas and evaluate the sensitivity degree in a particular area. This paper uses the revised universal soil loss equation (RUSLE) and GIS technique which has powerful space analysis functions...
The increasing number of users of mobile communication systems and the corresponding need for increased capacity show the importance of using a modulation scheme which is both power and bandwidth efficient. Continuous phase modulation (CPM) provides an attractive option for spectral efficient communication systems. Low-density parity-check (LDPC) codes combined with CPM has a potential to result in...
Spatial interpolation uses the geospatial features with known values and spatial relationships to predict unknown values. Spatial weights matrix is the most conventional way to represent spatial relationships when interpolating, where Euclidean distance is employed as the similarity measurement to tackle the spatial dependence problem. But spatial relationships of geospatial features should build...
In the past, the optometry instrument calibrated in diopter and astigmatism were usually performed by using human eyes. However, the larger uncertainty of measurement will be induced while observing the measuring patterns using human eyes. Therefore, based on the ANSI/ISEA Z87.1-2010 standard, this study presents the development of automatic optometry system, which comprises of the machine vision,...
Under the different light irradiation, the reflective and scattering intensity of skin image can be applied to evaluate many human health indices, such as oxygen saturation in blood, skin tissue aging or skin lesions (leukoplakia, turmoil cell, and so on). Due to the different absorption and scattering rate of skin illustrated by a variety of LED light source, we can perform the processing and analysis...
There are over 2000 capillaries in one large spinneret. Finding each capillary and designing its inspection path is very important. This paper develops a method of finding all capillaries and auto arranging inspection path that decreases inspection time significantly. The method applies to an existing automatic spinneret inspection which includes a three-axis motorized stage, a telcentric lens, two...
In this paper, several important inequalities for g-expectation and Choquet expectation are obtained by using back-ward stochastic differential equations (BSDEs) and comparison theorem. Markov inequality for g-probability is a special case of this inequality. If the generator g is independent on y and is linear in z, some classical inequalities for Choquet capacity are also presented.
New product innovations (NPI) continuously are vital for organizational sustained competitive advantage. Due to the nature of R&D intensity and multidisciplinary in the high-technology industry, it is difficult to develop new products by a single firm. Firms rely on external technological resources necessarily through several ways to maintain their pipeline of products, e.g., merger and acquisition...
Moral hazards and cognitive hazards play as dual barriers in inter-organizational knowledge transfer. However, in order to overcome these dual barriers, the governance mechanisms of appropriation concern and coordination are designed to assist focal firm to facilitate knowledge flow for inter-organizational knowledge transfer. The main purpose of this study is to develop an inter-organizational knowledge...
Finite element tearing and interconnecting method(FETI) is used to analyze the electromagnetic scattering of finite periodic structures. The original computational domain is partitioned into several non-overlapping sub-domains, the equivalent functional is established with Lagrange multipliers between the neighboring sub-domain to keep the electric field continuity on the interface. In the matrix...

Due to the advantage of flip-chip design in power distribution but controversial peripheral IO placement in lower design cost, redistribution layer (RDL) is usually used for such interconnection. Sometimes RDL is so congested that the capacity for routing is insufficient. Routing therefore cannot be completed within a single layer even for manual routing. Although [2] proposed a routing algorithm...
As one of key materials for improving the performance of ultrasonic motor, the wear of friction material plays an important role in contact friction properties and output performance of ultrasonic motors. However, the wear loss of friction material is small in the friction system of ultrasonic motor. If effects of wear of friction material on properties of ultrasonic motor studied with a real motor,...
Based on the finite element method, an electromechanical impedance (EMI) model for a damaged plate with imperfectly bonded piezoelectric patches is established in the paper. The property of bonding layer between the PZT sensor/actuators and the host plate is taken into account based on the peel stress model as well as the shear lag model. The damage appearing in the plate is modeled by a change in...
