Cell differentiation is a complicated biological process, involving lots of genes, which decide cell fate in early embryo development. These genes govern cell type formation (tissue formation). However, regulatory mechanism among these genes are not clear. In this paper, we infer gene regulatory effects for tissue formation to reveal gene regulatory mechanism based on state-of-the-art single-cell...
This paper addresses the problem of H-infinity (H∞) norm computation for an uncertain fractional order linear system based on LMI. In this paper, first, H∞ norm definition is given for an uncertain fractional order linear system. Then, H∞ norm method of the uncertain fractional order linear system on the basis of the Hamiltonian matrix is proposed by a LMI approach. According to a recent study, it...
Because there are many indexes when evaluating the performance of clothing fabrics, the method used widely is analytic hierarchy process (AHP). However, they often neglect the fuzziness when people give the intensity of importance on an absolute scale, selecting one index with membership of one and rejecting one index with membership of zero. In this experiment, we used the Fuzzy Analytic Hierarchy...
In this paper, the experiment of trajectory control of vehicle during a tyre blowout is carried out. Firstly, the evaluation criteria of motion vehicles during a tyre blowout are determined. Then, motion vehicle with a static PID controller in highway is discussed. Simulation results show that the static PID controller determined at a certain speed is not fit for the other speed as well. Instead,...
To make the elevator operates more smoothly and obtain quicker response speed, the traditional PID algorithm of elevator traction machine speed system needs to be improved. This paper adopts RBF neural network PID control algorithm to control the speed system of PMSM. The simulation results verify that the dynamic performances of PMSM have been improved. In addition, combined with the elevator speed...
Sub-circuit recognition (SR) is a problem of recognizing sub-circuits within a given circuit and is a fundamental component in simulation, verification and testing of computer-aided design. The SR problem can be formulated as subgraph isomorphism problem. Performance of previous works is not scalable as the complexities of modern designs increase. In this paper we propose a novel Prüfer-encoding based...
Automatic cell tracking for time-lapse images becomes more and more important for live cell studies because the manual tracking is extremely time consuming. In this paper, we proposed a method for C.elegans cell tracking based on probabilistic relaxation labeling (PRL). The experiment results obtained in this research indicate that our method could track the C.elegans cells with a high accuracy at...
The problem of detecting a subspace signal is studied in colored Gaussian noise with an unknown covariance matrix. In the subspace model, the target signal belongs to a known subspace, but with unknown coordinates. We first present a new derivation of the Rao test based on the subspace model, and then propose a modified Rao test (MRT) by introducing a tunable parameter. The MRT is more general, which...
This paper presents a cylindrical conformal monopulse phased array antenna for radars requiring large field of regard (FOR) and fast beam agility. The design technique is elaborated after a brief introduction of the system fundamentals and components. Key technologies including the feeding networks and beam-controller are analyzed and a prototype is built and tested, with the measured beam pattern...
As the basis of attribute reduction, core computation is one of the key issues in rough set theory. Actually, decision system is continuously changing, which leads to the inconsistent system. To deal with the problem before core computation, based on bucket sort and equivalence class partition, a new algorithm with time complexity of O(|P||U|) is proposed. After that, an effective approach is proposed...
This paper explored why employees share their knowledge with others based on three typical Congolese companies. A thorough content analysis was conducted in order to analyze our data, which were collected from an online survey. Our results indicated that motivations were divided into different types depending on different knowledge sharing behaviors. Learning new knowledge, knowledge self-efficacy...
Many scholars illustrate that innovation is the most important determinant of technological firm performance and the existing evidence has indicated the crucial role of knowledge flow and social interaction among partners in innovation activities, but little research has linked knowledge sharing and social capital with firm performance from a holistic perspective of innovation strategy. This paper,...
Due to the high uncertainties and perceived risk associated with using mobile payment, it is critical for service providers to build users' trust. This paper explored the critical factors influencing users' intention to adopt mobile payment from a trust perspective. The results are based on a survey sample of 193 participants. SmartPLS2.0 is employed in the data analysis. The findings indicate that...
The fluctuation of heart rate within each respiratory cycle that called respiratory sinus arrhythmia (RSA) is often observed in healthy persons. The present study investigated the respiratory modulation on the time span and amplitude indices of Electrocardiogram (ECG) and Photoplethysmogram (PPG). Totally 25 time span and amplitude indices from ECG of lead V5 and PPG of left finger were extracted...
A system implementation framework is presented for configurable high-speed IP over AOS gateway in this paper. Pipeline operation and asynchronous FIFOs are adopted to achieve rate matching and data synchronization between different clock domains. The format of configuration packet of IP over AOS gateway and finite state machine description of protocol are given. The simulation results show that the...
The distribution range of fiber-optical is wide, and the alarm information is scattered, the managers cannot monitor on the line fault in real time. The fiber-optical fault diagnosis is difficult, and the traditional diagnosis cannot form an effective fault diagnosis mechanism, the fault diagnosis effect is not satisfying. Large number of fiber-optical data can be used for the fiber-optical fault...
Particle concentration detection sensor which is based on light scattering particle concentration theory has high reliability, fast and easy using and so on. However, it demands to extract the small signal in the background of the large noise. It requires to use the modulated light source, so this paper design the circuit, it uses the digital multiplier and make the sensor work more steady and more...
PMSM has been used widely in elevator speed control system. Based on the mathematical model of PMSM and algorithm of inverter (CFPWM, SPWM, SVPWM), PMSM vector control systems are built. By the software of MATLAB/Simulink, the control systems using three inverter methods of CFPWM, SPWM, SVPWM are comparative simulated and analyzed.

An improved harmony search algorithm is presented for solving continuous optimization problems in this paper. In the proposed algorithm, an elimination principle is developed for choosing from the harmony memory, so that the harmonies with better fitness will have more opportunities to be selected in generating new harmonies. Two key control parameters, pitch adjustment rate (PAR) and bandwidth distance...
A low-complexity blind frequency-dependent I/Q imbalance compensation scheme is proposed based on linear prediction (LP) method. It provides non-iterative processing which reduces computational complexity. No special training sequence is used and I/Q mismatch calibration is performed using any received sequence. Frequency-dependent (FD) I/Q imbalance can be compensated simply by matching the filter...
