In this paper, we consider a simultaneous wireless information and power transfer (SWIPT) system with a full-duplex (FD) receiver and an energy-harvesting (EH) eavesdropper. The FD receiver decodes the information that should be kept secret from the EH eavesdropper and sends jamming signals to degrade the eavesdropper simultaneously using the energy it harvests from the source. An optimization problem...
In this paper, we propose a cooperative spectrum sensing method where the nodes detecting the primary user and those sending the sensing results are respectively selected in order to achieve energy efficiency. We formulate the problem of node selection and derive the optimized solution. The results show that the proposed method saves the energy compared to the case where the node selection is not...
The increasing demand on higher transmission speed and lower latency has become popular in 5G related researches. Cooperation is one possible solution to enhance system performance. In this work, we focus on the problem of enhancing the performance of cooperative among mobile terminals under the constraint of cooperative link capacity. Different from traditional researches, we consider the scenario...
Glioma is one of the most common brain tumors with high mortality and its histological grading and typing is important both in therapeutic decision and prognosis evaluation. This paper aims at using the high-throughput image feature analysis method to estimate the histological grade and type of a patient by using Magnetic Resonance Imaging (MRI) instead of histological examination. The proposed method...
Color temperature is one of the most significant characteristics for light sources due to its influence on human visual perception, circadian rhythm, emotion, work efficiency, and etc. Currently, it is common for LED light sources to render or tune color temperatures by mixing various color LEDs with different intensity. Existing methods can hardly take into consideration all the lighting requirements,...
With the increasing demand of transmission speed and more robust quality of service, the capacity constrained backhaul gradually becomes bottleneck in cooperative wireless networks, e.g. in Joint Processing mode of LTE-Advanced Pro. This paper focuses the fact of resource allocation with limited backhaul capacity in uplink cooperative networks, where two base stations (BS) equipped with single-antenna...
A novel hybrid NAND Flash management strategy optimization algorithm is proposed in this paper, which can greatly improve the write performance and the efficiency of garbage collection. We improve the write speed of the system by a self-adaptively dynamic address mapping mechanism and considering the spatial locality and temporal locality of the sector address mapping table. So we call our algorithm...
This paper describes the implementation of a previously proposed pothole detection system on Texas Instruments C6678 Digital Signal Processor (DSP). The system employs disparity maps as input followed by surface fitting and Connected Component Labelling (CCL) for pothole detection. Optimisations of the matrix calculation in the system algorithm have been made DSP friendly. Memory management has also...
This paper presents an intelligent lighting control system based on a wireless sensor network (WSN). The novel concept of an illuminance matrix (I-matrix) is implemented in the lighting control system of a cockpit. The I-matrix of a target working plane is obtained from some wireless photosensors through an RBF (Radial Basis Function) neural network. Then a genetic algorithm (GA) is used to optimize...
In building fire evacuation, good guidance can speed up egress process and occupants may be injured due to lack of information and guidance. There are many studies on building egress systems, which use relevant information (e.g., fire condition and its evolution) to calculate and provide guidance to occupants. However, information used to generate guidance may be uncertain, and it is difficult to...
Currently, community detection has led to a huge interest in data analysis on real-world networks. However, the high computationally demanding of most community detection algorithms limits their applications. In this paper, we propose a heuristic algorithm to extract the community structure in large networks based on local community attractive force optimization whose time complexity is near linear...
The convergence and local research ability of genetic algorithm is a well concerned research field in recent years. New evolution law of species is introduced in the paper, and based on the new evolution law, compulsive operator was introduced and a new genetic algorithm - compulsive genetic algorithm (CGA) was proposed to improve the convergence of GA. CGA takes advantage of the fitness of current...
