Abstract: Systemic Lupus Erythematosus (SLE) is a systemic autoimmune disease that affects any part of human systems. SLE most often harms the heart, joints, skin, lungs, blood vessels, liver, kidneys, and nervous system. Each SLE patient has a different set of symptom. Thus, SLE patients must be followed up closely by specialist. The treatments of this disease also base on the occurrence of symptom, doctor will check and consider carefully before taking any action to patient. Therefore, this research aims to develop a preliminary symptoms analysis and follow-up system for SLE patients for updating patient symptom to a doctor. The patient can report symptoms directly to the doctor without any necessity to see the doctor. On the other hand, the doctor can easily search and analyze patient data from the system instantly. Also, we propose a preliminary symptom analysis system in this paper. This system will analyze patient data by using a set of knowledge extracted from the doctor and specialist.

Abstract: The fourth generation of mobile telecommunications system (marketed as 4G-LTE) is being commercially and widely deployed. Security mechanisms are crucial to protect communications of mobile users from potential malicious attacks as well as to ensure revenue for 4G-LTE network operators. The randomness properties of the keystream generated by the current cipher suites in 4G-LTE standard are difficult to analyze and some vulnerabilities with regard to the integrity algorithms have been recently discovered. To address those issues, we present a detailed specification and security analysis of a bit-oriented stream cipher WG-16 as well as the corresponding confidentiality and integrity algorithms in this paper. Our experimental results on smartphones and comparisons with the cipher suites in 4G-LTE standard demonstrate that WG-16 is a competitive candidate for securing the emerging 4G-LTE networks.

Abstract: The numerical simulation method was adopted to study the multi-pass controlled rolling deformation process of the 400mm thick slab and the changing rule of the internal strain field. It was tried to simulate the center strain changes of the thick slab by two deformation processes which were the first rolling deformation process under a uniformed temperature and the second rolling deformation process after the waiting. It was shown that in the rolling process of super-thick steel plate both the first rolling process and the second rolling process could control the deformation of the central region. When the macro pressure rate was the same, the thinner was the slab, the greater pressure rate in the central region. The amount of deformation of both the first process and the second one was the same as 20%. The maximum strain was located in nearly one-tenth thickness of the surface layer and the minimum was in the center.

Abstract: Demand for objectivity, accuracy and online learning is becoming increasingly important to current evaluations for ride comfort. A data-based appraisal model of riding environmental comfort is proposed in this paper. Physiological indicators data is introduced into the improved supportvector regression(SVR), then, physiological indicators are used to learn online by correcting the parameters of the model. Excellent evaluation capacity is demonstrated through numerical examples, and rating accuracy is 95.6%.

Abstract: According to the beer bottle mouth defect recognition problem on modern production line, a new recognition method based on the combination the Hough Transform and the Midpoint circle algorithm was put forward. Firstly, extract edge pixels on beer bottle mouth mage and transform them into Hough space, which was to draw circles at each pixel location with bottle mouth radius. According to the circular symmetry, only 1/8 circle pixels were needed to draw circles, which were worked out by the Midpoint Circle Algorithm. The circles there overlapped each other to vote. Secondly, took the position with the highest votes as the center of bottle mouth and determined the bottle circular area. Divided the area into regions. Finally, count out the number of image pixels in each region and recognition beer bottle defect. In this paper detailed implementation steps with detection results were given. Experiments and its analysis shows: the algorithm can recognition beer bottle mouth defect correctly and quickly.

Abstract: With the application of the three-dimensional laser scanner, it makes possible that measure the shape and size of the sanding tree accurately. In this paper we put forward a new approach to reckon the volume of a single standing tree with three-dimensional laser scanner, explain the principle of the three-dimensional laser scanning system and how to establish the model of a single standing tree based on three-dimensional laser scanner and computer program. We have a test for a single standing tree volume with three-dimensional laser scanner, and also expatiate the specific process of reckoning the volume of a single standing tree with the model. As shown by the test, we can work out fast and exactly the single standing tree volume. If the approach can be apply on the measurement of stand volume, there has a great improvement in the precision and efficiency of measurement.

Abstract: This paper deduces the MIMU miscalibration model from actual installation relation to meet IMU product industry-applied needs. Through analysis and simplification it obtains a linearized model using the least-square method. The simplified linearized model is used to align IMU. Also the parameters error analysis is conducted for further analysis of the calibration result. Finally, simulations are performed to test the algorithm, which indicates that this algorithm can perform the IMU calibration on high-accuracy level.

Abstract: A TR and ultrasonic focusing wheel probe is designed for some special engineering testing item. Ultrasonic TR thickness testing and focusing detection can be carried out without coupling medium. With the testing system and the probe set on a control machine car, aligned and marginal testing for steel plates quality and the thickness testing of corroded pipe wall can be accomplished by dry couple method. The processing method of detection signal and the design of peripheral circuit are also introduced in this paper.

Abstract: With the development of construction tissue engineered cornea by using biomaterials and seed cells,how to measurement transparence of tissue engineered cornea need to be solved. Purpose of the paper is bringing forward a new method to measurement transparence of tissue engineered cornea. According to the definition of corneal transparence, a beam of light is divided into equal two beams of light by spectroscope. In which a beam of light pass through cornea. Ratio of light energy flow that light passed cornea and the other one is calculated. The usual optical and measuring instruments were used, such as sensors for illumination and Data acquisition (DAQ) card. The real-time measuring device for corneal transparence is designed and implemented. The method and device are effective to real-time measurement of tissue engineered cornea transparence through the elements analysis and experiment.

Abstract: With the mobile Internet developing in China, the problem of information overload has been brought to us. The traditional personalized recommendation cannot meet the needs of the mobile Internet. In this paper, the recommendation algorithm is mainly based on the collaborative filtering, but the new factors are introduced into the recommendation system. The new system takes the user's location and friends recommendation into the personalized recommendation system so that the recommendation system can meet the mobile Internet requirements. Besides, this paper also puts forward the concept of moving business circle for information filtering, which realizes the precise and real-time personalized recommendations. This paper also proves the recommendation effects through collecting and analyzing the data, which comes from the website of dianping.com.
