The fluorescence-based integrated chemical and enzyme sensor arrays on which two kinds of 10 μm i.d. sensor spots were arranged alternately on one chip, were developed by using microcontact printing. FITC, ruthenium complex and europium tetracycline was stamped onto a DLC sputtered glass slides for pH, oxygen and hydrogen peroxide sensors, respectively. After printing of oxygen sensor spots, pH sensor...
The development of a wireless handheld terminal for indoor gas concentration detection is presented in this paper. The major motivation for this work is to develop a distributed wireless measuring system suitable for metal-oxide semiconductor gas sensors, usually with a wide range resistance (e.g. 0~100 MΩ), for indoor gas concentration detection. The handheld data acquisition terminal is developed...
This paper gives a new method to measure the speed of strip based on linear CCD. For the surface of any strip, the image signal collected by linear CCD can be seen as image with strip feature by accumulating for a while, and the directivity of the strip relate to the speed of the strip. The power spectrum of the strip image can reflect the degree of thickness and the directivity of the strip. So the...
To solve the problem of supplier selection, the author considered the multiple attributes and established multi-attribute decision making model decided by many people. Firstly, the supplier's comprehensive scheduling is given by using TOPSIS method ,then determining group scheduling which is the most consistent to each member's scheduling by using Cook - Seiford function included in SCF (social choice...
This paper presents a concrete implementation of the Fuzzy Rule Interpolation (FRI) method called `FIVE'. FIVE is an acronym for Fuzzy rule Interpolation based on Vague Environment. The method itself tends to be a fast and simple to use application oriented FRI technique. Therefore the main goal of this paper to study the speed performance issues of the implementation. First a brief introduction to...
We describe the methodology; the design and the implementation of scheduler block of interconnect. The scheduler block is implemented in Verilog using SYNOPSYS tool's DVE and Design_vision. The interconnect is capable of handling 72 bit packets and a total of 32 packets at a time. There are total 8 devices and we have to establish the communication between them. Each device consists of an input block...
This article takes the two-stage screw type solar array which has multi-deployment and lock function as a study object, and simplifies the joint hinge as rotation vice according to the transmission order of multi-deployment and lock joint hinge. Based on the kinematics characteristic analysis of solar array's deployment and the Kane dynamic equation, the dynamics analysis model of solar array's deployment...
The current skill evaluation of GMDSS certification is mainly carried out by human being, which involves many man-made factors, and is hard to test the real level of personnel being assessed. Due to this fact, the present study designs an automatic evaluation system. Based on a B/S structure, the system realizes an automatic assessment content algorithm according to category and area. It simulates...
To make the members for group discussions well-mixed, the compound variable of four weighting factors is used to meet the quantification of the four judging criteria. Exclusion force is introduced here to evaluate whether a certain member should be assigned into a certain group or not. Then the algorithm is realized with the use of computer programs with the current state be used. Analysis of the...
The Maximum power point tracking algorithms is essential to improve the efficiency of PV system. In order to improve the efficiency of PV system, a new algorithm is proposed based on conventional perturbation and observation method. The algorithm proposed a variable perturb step that can be changed automatically and PV system can adjust the step length according to the changed power. So the response...
The text posed a brand new counting method of using infrared which was distinct to the normal usage in the product line. By adopting the infrared lattice and the appropriate recognition algrithom, the MCU is able to detect the status of traffic flow in complicated circumstance, easily and economically. All this enables to improve the real time information of traffic condition, furthter to instruct...
Because of the high computation demand for multimedia applications like video decoding, there is a need to develop flexible and high performance reconfigurable computing architectures. Taking video decoding algorithm as an example, we propose a reconfigurable computing realization solution of multimedia application. Based on the analysis of parallelism in video decoding algorithm, a hardware platform...
The biconical dipole antenna is frequency independent antenna. A dipole antenna is a narrowband and frequency dependent. In this paper a linear array of five biconical antennas with cone angle 30 is modeled in WIPL-D software and analyzed. Radiation pattern, gain, impedance and Sparameter plots of the array are analyzed and presented for 1-5 GHz frequency range. Mathematical equations for the parameters...
Java is one of the most popular programming architectures because of its platform-independence. Its platform-independence depends on Java virtual machine JVM. Compared to executing class file on hardware JVM, executing class file on software JVM is much slower. By studying we master the component architecture and the working principle of software JVM based on the class file to explain the implementation...
Image registration is the process of overlaying two or more images of the same scene taken at different times, from different viewpoints, and/or by different sensors. It geometrically aligns two images the reference and floating images. Medical image registration concentrates on aligning two or more images that represent the same anatomy from different angles and are obtained at different times. In...
The article stress on explanation and comparison of modern key technologies and main products of storage and backup system, by introducing original structure and current structure in stated-owned enterprise.
The Multiple Input Multiple Output (MIMO) radar concept exploits the independence between signals at the array elements unlike beamforming which presumes a high correlation between signals either transmitted or received by an array. Radar Cross Section (RCS) of a complex target varies with both transmitted frequency and target geometry. By widely separating transmit and receive antennas, MIMO radar...
Tow ship noise is a typical multi-path directional interference, and the receiving response of which on towed line array is worthy of in-depth study. Firstly, the sea trial data was analyzed to summarize the tow ship noise characteristics. Then the underwater acoustic field of tow ship noise was modeled to achieve the power distribution of the noise. Finally an important result was obtained, that...

The design plan and HSPICE measurement of a high acquisition speed for a sample of 8-bit CMOS differential successive approximation register (SAR) Analog-to-digital converter (ADC) are presented. The operation of the conventional main switch-capacitor array is divided into two switch-capacitor arrays. Such that, one switched-capacitor array is used to define the four most-significant bits, while the...
