This paper proposes a new multiobjective optimization approach to designing a fuzzy logic system (FLS) using process data and applies it to the wall-following control of a mobile robot. The objectives considered include both the interpretability and control performance of the FLS. It is assumed that no off-line training data are available in advance, and the rule base is initially empty. All rules...
In this study, an image segmentation algorithm for processing Next-Generation Sequencing (NGS) fluorescence data is proposed. In NGS applications, fluorescent spots are randomly distributed, the number of spots is large, and the sizes of these spots are small. All the characteristics make the conventional segmentation algorithm not as efficient. To speed up the segmentation process, we propose a hardware-compatible...
Recently, liquid chromatography coupled to mass spectrometry (LC-MS) has become a standard technique for identifying differential abundance of peaks as biomarkers. Two major problems in the preprocessing of LC-MS data analysis are how to adjust and align multiple LC-MS datasets efficiently and correctly. Hence, an effective algorithm is needed to adjust the variation in retention time and align protein...
Energy efficiency is of great importance for the wireless sensor network (WSN). A popular way to save energy is to construct clusters for data aggregation and forwarding. This paper studies the distributed cluster algorithm to improve the energy consumption efficiency. We observe that the cluster head has to lie within the transmission range of the base station (sink node) and the distance between...
Transient faults have become a key challenge to modern processor design. Processor designers take Architectural Vulnerability Factor (AVF) as an estimation method of micro-architectures soft error rate. Dynamic, phase-based system reliability management, which tunes system hardware and software parameters at runtime for different phases, has become a focus in the field of processor design. Phase characterization...
Nowadays, more and more interest has been shown in the automatic categorization methods to organize media data as there are increasing number of videos data in people daily life. In the image processing domain, clustering method is the backbone of person specific searching and image retrieval from an image sequence or database. This paper presents a fast image clustering algorithm based on human face,...
In recent years, the mass spectrometry technologies emerge as useful tools for biomarker discovery through studying protein profiles in various biological specimens. In mining mass spectrometry datasets, peak alignment is a critical issue among the preprocessing steps that affect the quality of analysis results. In this paper, we proposed a novel algorithm named Two-Phases Clustering for peak Alignment...
Integrated optical and wireless networks are considered as the next generation access networks because of the potential benefits from both technologies. In this paper, we consider the integrated BS/ONU (IBO) placement problem in the hybrid EPON-WiMAX system to efficiently utilize network resources as well as reduce the system cost. We propose a modified clustering algorithm (MCA) to obtain the near-optimal...
This paper studies how to increase availability and survivability of WSN by selecting a suitable cluster head. For this purpose, we propose a relative distance based clustering scheme (RDCS), to promote the efficiency of energy utilization. In RDCS, both the relative distance and the residual energy are taken into consideration for cluster head selection. Simulation results show that RDCS has better...
This paper proposes algorithms for establishing connectivity and location estimation in wireless sensor networks. The algorithms exploit the information flow while coping with distributed signal processing and the requirements of network scalability. Once the estimation procedure and communication protocol are performed, sensor clusters can be merged to establish a single global coordinate system...
The wireless sensor network is a type of the wireless ad-hoc networks. It is composed of nodes with limited battery power. One of the most critical issues in designing wireless sensor networks is to minimize the energy consumption for longevity. In this paper, we first entirely analyzes state clustering protocol and LEACH routing protocol, then present a novel clustering routing protocol for wireless...
