The population diversity greatly affects the evolutionary efficiency and solution quality of gene expression programming algorithm. Population diversity should be preserved by keeping certain distance between individuals in the population. Edit distance can describe the similarity of individuals well. Crossover is a way to create and maintain the distance of the individuals. In this paper, we propose two edit distance based crossover operators. Experimental results show that the proposed farthest edit distance based crossover operator is able to preserve the diversity of population and solve the optimization problem more efficiently.

Comparing the imaging features on the ordinary fa-value and high-b-value DWIBS with that on the enhanced imaging, to explore the value of 3.0T MR high-b-value diffusion weighted imaging with background suppression (DWIBS) in detecting the cerebral metastases. 41 patients with cerebral metastases confirmed by clinically and pathologically were collected. All the patients underwent conventional MRI and contrast-enhanced MRI, and DWIBS used two types b-value: ordinary b-value (b=0, 1000s/mm2) and high-b-value (b=3000s/mm2). Evading cystic necrosis area, the signal intensity (SI), background noise and apparent diffusion coefficient (ADC) value of tumor parenchyma and adjacent normal white matter were measured. The averages of signal to noise ratio (SNR), contrast to noise ratio (CNR) and contrast ratio (CR) were computed from these data. The lesion diagnosis accuracy rate of high-b-value DWIBS was better than that of ordinary b-value. On high-b-value DWIBS sequence, the CNR, CR and SI-lesion/ SI-normal of brain metastasis was significant higher than that of ordinary b-value DWIBS sequence (P<;0.05). And the SNR was significant lower than that of ordinary b-value DWIBS sequence (P <; 0.05). The CNR, CR of Contrast-enhanced T1WI was significant higher than that of normal brain tissue (P<;0.05). The ADC value in High-b-value DWIBS sequence was lower than that in ordinary b-value DWIBS sequence (P <; 0.05). Conclusion High-b-value DWIBS sequence showed a great value in detecting cerebral metastases. It was a simple method and could be avoiding potential harm of contrast agent for the human bodies.

This paper investigates uncertain SDOSs (singular delta operator systems), regarding robust H∞ control and robust H∞ performance analysis. To ensure robust admissibility, we introduce the definition of generalized quadratic admissibility. Through LMI (linear matrix inequality), with the support of a necessary and sufficient condition, an uncertain singular delta operator system is generalized quadratically admissible with a prescribed performance. Then, based on these conclusions, the design problem of a robust H∞ controller is considered for uncertain SDOSs. In terms of an LMI, the existence condition of a suitable robust H∞ controller is derived, and the corresponding design method is also presented through the solution to the LMI. Also, a numerical example is adopted to show the efficiency of the theoretical results in this paper through Matlab-LMI toolbox.

In this paper we have considered a new resourse sharing approach for wireless access which is based on power assignment strategy, where two sources transmit their information simultaneously to the destination with the different power but use the same sub-band (time-frewquency unit). It discusses the concept of non-orthogonal multiple access (NOMA) which has a power multiplexing at the transmitter side to improve the spectrum efficiency and a successive interference cancellation (SIC) at the receiver side. Multi-antenna techniques have been deeply studied during the past decade to boost system performance by virtue of spatial multiplexing and/or spatial diversity. It is proved that NOMA combined with MIMO techniques can achieve further system performance improvement. In this paper, the SIC structure is designed, and the MMSE-SICand ZF-SIC algorithm is simulated and the effects of different order is anlysised. The conclusion is that the MMSE-SIC algorithm based on SINR ordering has lower complexity and better performance and is more suitable for NOMA.

An intellectual non-invasive anesthesia machine monitoring system is analyzed in this paper. The system consists of a data acquisition terminal, a communication module and a PC/104 monitoring platform. The data acquisition terminal detects the real-time parameters including tidal flow, airway pressure and oxygen concentration. These parameters will be transmitted to the monitoring platform through serial ports for records and analysis. In this way, the flow, pressure and concentration of the medicine can be controlled for the general anesthesia on the patient. With advantages of intuitive alarm signals, safe and reliable environment, and complete function, the system also realizes the expert diagnosis by XMLHttpRequest and Server-Sent Events technology. After repeated validation test, the system can work steadily and will have a wide application prospect in the market.

With the popularity of smart phones and the rapid development of wireless communication technologies, people tend to determine their indoor location in the complex indoor environment such as a library, exhibition hall and shopping malls using location-based services. However, in many scenarios, two-dimensional positioning system has been unable to meet the needs. In this paper, we research on the three-dimensional positioning system using location fingerprinting techniques, improve the algorithm based on K Nearest Neighborhood, and establish the three-dimensional positioning system. The results showed that our simulation model can achieve a more accurate result than two-dimensional models.

Aiming at weighted social networks, a random perturbation method based on vectors similarity is proposed. It can protect structures and edge weights of weighted social networks in multiple release scenarios. First, it partitions weighted social networks into t sub-graphs by the segmentation method based on vertex cluster using edge space of graph theory, describes these sub-graphs by vectors, and constructs vector set models of weighted social networks. Then, it adopts weighted Euclidean distance as the metrics of vectors similarity to construct the released candidate sets of t sub-graphs according to the threshold designated by publishers. Finally, it randomly selects vectors from the candidate sets to construct the released vector set, and builds the published weighted social networks based on the released vector set. The proposed method can resist multiple vertex recognition attacks, force the attackers to re-identify in a large result set that the existential probabilities of the vectors are same, and increase the uncertainty of recognition. The experimental results on the actual datasets demonstrate that the proposed method can preserve the security of individuals' privacy, meanwhile it can protect some structure characteristics for social networks analysis and improve the released data utility.

In the space environment, a large number of cosmic rays often results in transient faults on on-board computers. And one of the main problems caused by these faults is the control flow errors in the program. This paper proposes a software-implemented control flow error detecting and correcting approach for the linear assembly named DCCLA. DCCLA firstly divides the program into loop blocks and non-loop blocks and assigns the formatted labels for the blocks. Then based on the mechanism of instructions counting, DCCLA inserts counting and comparing instructions into every block, with the purpose of detecting and correcting the control flow errors occurred inter-block and intra-block. In order to correct the data flow errors caused by the control flow errors, DCCLA backups the loop state and live variables. One advantage of DCCLA is that it can be configured flexibly according to the requirement of reliability and performance. The results of fault injection experiment shown that, the average fail rate of programs with DCCLA has decreased to 4.25% with the cost of increasing the average executing time by 41.7% and increasing the average program space by 46.7% DCCLA has the least influence on performance and space overhead and correspondingly higher reliability among three typical control flow detecting algorithms.

Clustering protocol for data gathering is one of the effective ways to solve the energy hole problem in wireless sensor networks. However, most of the existing clustering protocols focus on the network model with uniform node distribution. They cannot effectively apply to the real network where the sensor nodes are randomly non-uniformly deployed. In this paper, we propose an energy-balanced clustering routing protocol (EBCRP) based on task separation. In this scheme, the network is firstly divided into clusters by using global information. And each of them has the same number of sensor nodes in order to balance the energy consumption of intra-cluster. In succession, task separation, the tasks of traditional single cluster head are separated and achieved by two cluster heads respectively, is proposed to reduce the traffic burden for single cluster head. Then, we explore an energy-efficient and reliable inter-cluster routing algorithm, which considers comprehensively three factors: residual energy, distance and available buffer space of nodes. Simulation results and performance evaluation of EBCRP show significant improvement in network lifetime and energy balance.

Traditional Chinese Medicine (TCM) is a medical system with a long history, and is still in-practice today. The TCM domain has a plenty of archaic and abstruse terms and a complex conceptual system. In the information age, a lot of work has been done to digitalize TCM knowledge assets for information retrieval, knowledge discovery, and other applications. A domain ontology helps to standardize TCM terminology and can be very useful in TCM informatics. Therefore, we have engineered a domain ontology named Traditional Chinese Medicine Language System (TCMLS), which contains approximately 300,000 terms, 120,000 concepts, and 1,270,000 semantic relations. The semantic network framework of TCMLS was published as the ISO technical specification "ISO/TS 17938:2014" in 2014. TCMLS has been successfully applied in many applications such as knowledge visualization, terminology integration, and text mining.

TCMLS has been successfully applied in many applications such as knowledge visualization, terminology integration, and text mining.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133372007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
