Different kinds of operating environment and multiple mission conditions result in dynamic mission definitions, stages and profiles of complex systems like avionic systems in airplanes. A complex system usually consists multiple parts, units or subsystems which perform limited functions and are hardly under operation for all time. Based on such circumstances, traditional system reliability and testability...
Nowadays, energy conservation is one of the most talked about issues in our life, it is also increasingly important in dynamic flexible flow shop scheduling problems. Previous research did much on how to minimize total earliness and tardiness of all jobs, or to achieve just-in-time production, whereas little effort has been made on how to save energy. Therefore, to address such need, a dynamic machine...
For the early diagnosis and treatment, a needle insertion for biopsy and treatment is a common and important means. To solve the low accuracy and high probability of repeat surgery in traditional surgical procedures, a computer-assisted system is an effective solution. In such a system, how to acquire the accurate orientation of the surgical needle is one of the most important factors. This paper...
This paper introduces novel 7-T pseudo-CMOS for enhancement mode and 6-T pseudo-CMOS for depletion mode inverter circuit architectures. The designs are built around mono-type of TFTs and consume less power consumption than existing 4-T pseudo-CMOS circuits. In addition, they provide steep transfer curves, along with embedded control for compensation of device parameter variations. Analysis of the...
Single image dehazing with its ill-posted characteristics has been a popular challenge in low-level vision. In this paper, an alternative approach of solving a single hazy image is presented. Initially, we propose a new haze model in consideration of multiple scattering during light propagation. Compared with the traditional dichromatic atmospheric scattering model, our new model requires fewer restrictive...
A parameter optimization method based on relevance measurement in a prediction system is proposed. Meaning of dependency in parameter optimization is analyzed and reference standards of parameter optimization are proposed. This method is used in BP neural network to select the input parameter in a residual life prediction system of rechargeable batteries. The case study shows a good effect on initial...
Background motion and visual clutter are present in almost all augmented reality applications. However, there is minimal prior work that has investigated the effects that background motion and clutter (e.g., a busy city street) can have on the perception of virtual object motion in augmented reality. To investigate these issues, we conducted an experiment in which participants' perceptions of changes...
In this paper, we propose a distributed precoder design algorithm for suppressing the inter-cell interference(ICI) and maximizing the average throughput of a multi-cell multi-user multi-input multi-output(MU-MIMO) system. Motivated by the recent results of the distributed signal-to-leakage-plus-noise ratio(SLNR) model for ICI coordination(ICIC), we design a joint optimization algorithm to achieve...
This paper analyzes the parameters of power-supply network and the harmonic characteristics of loads by researching the structures and operation ways of traction power-supply system of the train. It also analyzes and compares the current methods in removing current harmonics. Eventually, it comes up with the way using chain high-voltage APF to eliminate the harmonics. This paper describes the main...
The epoxy insulators are widely used in the vacuum equipments. Some investigators suggest that the surface flashover voltage of epoxy resin is improved by inorganic fillers. The fillers maybe restrain the accumulation of the surface charge. This paper use the Al2O3·3H2O powder(particle size of 1um)to improve the voltage holdoff capability of the epoxy insulator under nanosecond voltage pulse. The...
The paper proposes an organization model hosted in the LDAP directory server. And it expands the scope of model utilization, gives the technical method which is capable of dealing with the heterogeneity, distribution of the organization model, and the transparency of the model to its users. Then the role-based access control (RBAC) technology has been used in the model to implement the control of...
