When the almost disturbance decoupling problem by state feedback is solvable, in any solutions are present some fixed poles and infinite poles in the closed loop system, which cannot be freely assigned. An optimal geometric solution with maximal pole placement can be achieved. We present here a new approach to achieve the optimal geometric solution, and the accurate expression of the optimal geometric...
Aiming at the disadvantage of system efficiency, a novel control strategy of maximizing energy saving while meeting the cooling demand for vapor compression refrigeration cycle (VCC) is presented. The VCC system is a core element in heating, ventilating, and air-conditioning (HVAC) system, and its coefficient of performance (COP), a measure of system efficiency for VCC system, is strongly influenced...
Based on particle swarm optimization (PSO) algorithm for optimal design of PID controller, a method is proposed to navigate of a two-wheeled mobile robot from a given initial configuration to a desired final configuration in an unknown environment filled with obstacles. The mobile robot can follow a wall with PID control to adjust motor speed and avoid obstacles with moving square method in an unknown...
Heparin is a member of the negatively charged glycosaminoglycan family which is present in the extracellular matrix of all eukaryotic cells. Heparin-binding proteins (HBPs) play an important role in various biological processes like cell signaling, development, and angiogenesis. Interestingly, despite their wide array of functions, very little knowledge exists on the precise structural determinants...
Monochromatic-square-free Ramsey grid coloring is a challenging problem to solve computationally. It relates to Ramsey-theoretic combinatorics and multiple party communication protocol complexity. Recently, using a parallel search algorithm on cluster based super computers, a 2-color 14x14 solution was found in 2.5 hours. In this paper, we report on another approach to solve the monochromatic-square-free...
With the development of the society, distance education and training gradually shows some characteristics similar to the service industry, such as invisible, cannot be stored, heterogeneous, serving and consuming in the same time and so on. To gain a bigger market share in competition and more reputation and brand value in development, distance education and training institutions must pay great attention...
A single-channel 1.0-GS/s 8-bit Voltage-Buffer-Free Pipelined-Folding-Interpolating analog-to-digital converter (PL-FAI-ADC) is presented. Grouped T/H blocks are adopted to cancel the voltage buffer between the T/H block and the pre-amplifiers array. A new full-digital T/H switch is proposed to cancel the bootstrapped capacitor, which can save the chip area grandly. An improved single-diode switch...
In this paper, an oil exploration software is designed, introduced and implementation. The software is based on the procedures of oil exploration and seismic prospecting. In the environment of Microsoft Visual Studio 2008 with the C++ programming language, the standard SEG-Y seismic data is successfully transferred into visible geological sectional view and histogram chart, which makes the geologists...
The proportionate normalized least-mean-square (PNLMS) algorithm with individual activation factors (IAFPNLMS) converges fast when the echo path is highly sparse, and has been used in system identification. Unfortunately, it suffers from slow convergence speed after the fast initial process. To solve the problem, in this paper, the idea of mu-law PNLMS (MPNLMS) algorithm is introduced into the IAFPNLMS...
With increasing diversity and heterogeneity of content access devices and network technologies as well as user preferences, content delivery has evolved into a matter of ubiquitous service where production, delivery and access of content form major challenges for content provider, network operator and user respectively. Content adaptation has been widely acknowledged as one of the most important aspects...
Internet of Things (IoT) built on the existing (mobile) Internet has emerged as a solution to effectively interact with things around us. In order to meet the actual needs of monitoring laboratory equipments in college/university, we design and implement a smart equipment monitoring system to monitor the location information of the equipments based on ARM and RFID technology in this paper. Meanwhile...
This paper presents a review of the status of power generation with nonaqueous working fluids from low-temperature thermal resource, the features, equipment composition and working processed as well as comparison of two main types of thermodynamic cycles which are Organic Rankine Cycle(ORC) and Kalina Cycle and nonaqueous working fluids including their classification and filter criteria for thermodynamic...
Understanding and exchanging XML documents with multilingual markups is a common requirement. This paper proposes a schema design method to support multilingual markup of XML based on two attributes introduced for every element to be transformed, i.e., locID and attrList. It ensures that all XML instances derived from the translated schema no matter what language used and how the name is translated...
This paper describes a novel offering of a US- based course in Computer Science at a Chinese university. A senior-level Algorithms course from the University of Washington was offered at Beihang University in Beijing, China through Tutored Video Instruction, whereby lectures recorded in class at the University of Washington were subsequently shown at Beihang and facilitated by local teaching assistants...
