Internal repeats are widely found in proteins and considered to be important in protein evolution and function. Three major types of internal repeat including domain, solenoid, and fibrous repeats are. These repeats may involve in protein-protein interaction as well as binding to various ligands such as DNA and RNA. For example, the tetratrico peptide repeats (TPR) that are involved in cell-cycle...
In this paper, we present a new heuristic that generates broadcast schemes in arbitrary networks. The heuristic gives optimal broadcast time for ring, tree and grid if the originator is on the corner. Extensive simulations show that our new heuristic outperforms the best known broadcast algorithms for two different network models representing Internet and ATM networks. It also allows to generate broadcast...
This paper proposes a new hybrid-source switched-capacitor multilevel converter for electric vehicles. The key is to integrate the battery-ultracapacitor hybrid power source into the switched-capacitor multilevel converter. Hence, the problem of high capacitive charging current of the switched-capacitor multilevel converter can be solved, and the dynamic voltage equalization of battery packs can be...
As a newly rising topic in network multicast Held, application layer multicast is widely concerned. Analyze and compare technical proposal of application layer multicast protocols Narada, NICE and HMTP, etc. used by typical wide P2P streaming media service model, make an outlook on study prospect of P2P streaming media and summarize study status and its existing problems of P2P streaming media, which...
By analyzing the topological relationships between network elements, this paper extends a turn-based algorithm for the network loading of logit type, which has a structure similar to Dial's algorithm. Based on the conservation of flows on links, the algorithm computes directly the link flow and turn flow pattern that not only agrees with the logit path-choice process but also takes into account the...
Based on the technology of Mobile Ad-hoc Network (MANET), we design and implement an Audio Conferencing Testbed (ACT) that is used for a group of people to set up virtual audio conferencing room to complete certain mission in places where network infrastructure is unavailable. ACT is built on popular Windows operating system with off-the-shelf IEEE802.lt (a.k.a. Wi-Fi) adapters as the enabling technology...
Infrasound is ideally suited to provide essential information of these earthquakes without any invasive measures. This necessitates automatic processing of the data as the captured phenomena need to be sortedbefore further analysis can be undertaken. Extracting the physical characters of different signals by signal processing such as Fourier Transform and Wavelets Transform are generally employed...
We investigate the problem of clustering on distributed data streams. In particular, we consider the k-median clustering on stream data arriving at distributed sites which communicate through a routing tree. Distributed clustering on high speed data streams is a challenging task due to limited communication capacity, storage space, and computing power at each site. In this paper, we propose a suite...
This paper investigates feasible topologies of VSC-HVDC system for interconnecting large-scale off-shore wind farms. The corresponding control strategy is developed for coordination and control of the corresponding VSC-HVDC systems. A case of 5-terminal VSC-HVDC system is developed in MATLAB/ SIMULINK to demonstrate the validity of the proposed scheme. The proposed scheme may enable optimal integration...
The purpose of this paper is to improve the risk evaluating quality of engineering project. The topology structure of particle swarm optimization (PSO) based BP (PSOBP) neural network is described, the principle of PSOBP neural network is introduced, and the implement step of PSOBP neural network is given. The combination algorithm is applied to risk evaluating for the engineering project, and its...
