Due to historical reasons and urbanization progress, demographic development change has promoted China to enter an aging society and the elders' demand for medical care and health care has increased rapidly. Meanwhile, the rapid development of information technology is driving the "Smart Care for the Elderly" model which is based on the Internet and regards the internet of things as the medium which has gradually developed into a complete a system, and a series of solutions have been formed. This paper started with the analysis of China's elderly population status quo, combed academic studies on domestic and foreign "Smart Care for the Elderly" and applications in recent fifteen years and explored how to build a comprehensive "Smart Care for Elderly" solution with improved functions which incorporates such key elements as information technology and social sciences.

The Traveling Salesman Problem (TSP) belongs to the class of NP-hard optimization problems. Its solving procedure is complicated, especially for large scale problems. In order to solve the large scale TSPs efficiently, this paper presents a bilevel genetic algorithm with clustering (BLGAC). BLGA-C uses a clustering method to divide a large scale TSP into several subproblems, each subproblem corresponds to a cluster. K-Means clustering method is adopted in this paper. In the lower level, a genetic algorithm is used to find the shortest hamiltonian cycle for each cluster. All these clusters can be handled parallelly. Then, we need to select two nearest vertices between two clusters, and determine which edges will be deleted from the shortest hamiltonian cycle for each cluster, and which edges will be linked for combining two adjacent clusters into one. Repeat this procedure until all clusters are joined into one whole tour. Different combing sequences among clusters will result in different travelling tours, searching for the shortest is our purpose. Therefore, in the higher level, a modified genetic algorithm is designed for integral optimization with the objective of shortest the whole traveling tour. At last in this paper, we trial run a set of experiments on benchmark instances for testing the performance of the proposed BLGAC. Experimental results demonstrate its effective and efficient performance. © 2016 IEEE.

—The explosive increase and ubiquitous accessibility of visual data on the Web have led to the prosperity of research activity in image search or retrieval. With the ignorance of visual content as a ranking clue, methods with text search techniques for visual retrieval may suffer inconsistency between the text words and visual content. Content-based image retrieval (CBIR), which makes use of the representation of visual content to identify relevant images, has attracted sustained attention in recent two decades. Such a problem is challenging due to the intention gap and the semantic gap problems. Numerous techniques have been developed for content-based image retrieval in the last decade. The purpose of this paper is to categorize and evaluate those algorithms proposed during the period of 2003 to 2016. We conclude with several promising directions for future research.

In this paper, we present our work in TREC 2016 Clinical Decision Support Track. Among five submitted runs, two of them are based on summary topics and the others on note topics. In summary version run, we expand the original text with external data on web. Note topics are much longer than the summary, which contain a significant number of medical abbreviations as well as other linguistic jargon and style. An automatic method and a manual method are applied to process note topics. In the automatic method, we utilize KODA, a well-known knowledge drive annotator, to extract key information from the original text. In the manual one, we ask medical experts to diagnose and give their advice. For all of the five runs, we adopt Terrier search engine to implement various retrieval models. Furthermore, results combinations are applied to improve the performance of our model. © 2016 25th Text REtrieval Conference, TREC 2016 - Proceedings. All Rights Reserved.

Chimera states in spatiotemporal dynamical systems have been investigated in physical, chemical, and biological systems, and have been shown to be robust against random perturbations. How do chimera states achieve their robustness? We uncover a self-adaptation behavior by which, upon a spatially localized perturbation, the coherent component of the chimera state spontaneously drifts to an optimal location as far away from the perturbation as possible, exposing only its incoherent component to the perturbation to minimize the disturbance. A systematic numerical analysis of the evolution of the spatiotemporal pattern of the chimera state towards the optimal stable state reveals an exponential relaxation process independent of the spatial location of the perturbation, implying that its effects can be modeled as restoring and damping forces in a mechanical system and enabling the articulation of a phenomenological model. Not only is the model able to reproduce the numerical results, it can also predict the trajectory of drifting. Our finding is striking as it reveals that, inherently, chimera states possess a kind of "intelligence" in achieving robustness through self adaptation. The behavior can be exploited for controlled generation of chimera states with their coherent component placed in any desired spatial region of the system. Copyright © 2018, The Authors.

As the new era of the Internet of Things(IoT) is driving the evolution of conventional Vehicle Ad-hoc Networks into the Internet of Vehicles(IoV), vehicles are equipped with different kinds of sensor and become a sensing node themselves in IoV. Consequently, complexity of the automotive electronic system inside the vehicles are daily increasing. To guarantee the safe operation of vehicles, it is of great significance to acquire vehicle data in real-time to realize the on-line diagnosis, cybersecurity attacking detection and et al. In this paper, we propose to realize a STM32-based data acquisition system(DAS), where the vehicle data transferred on CAN networks are acquired through the OBD2(On-Broad Diagnosis) interface. And then, the acquired vehicle data are parsed and analyzed preliminarily according to the OBD2 protocol, and then shown on a LED displayer. Through the implementation of a prototype system, the feasibility and effectiveness of the proposed design of DAS is verified.

IEEE International Conference on Robotics and Automation (ICRA)

Tracking for planar objects is an important issue to vision-based robotic applications. In direct visual tracking (DVT) methods, the similarity between two images is often measured through the sum of squared differences (SSD) especially with the efficient second-order minimization (ESM) due to its simplicity and efficiency. However, SSD-based ESM is not robust to illumination changes since it is usually built upon the brightness constancy assumption. Contrast to image brightness, gradient orientations (GO) are invariant to both linear and non-linear illumination changes as verified in practice. Based on GO, we propose an illumination insensitive ESM method for planar object tracking in this paper. In order to introduce GO into the ESM, we generalized the original ESM formulas for multi-dimensional features. In addition, a denoising method based on the Perona-Malik function and a mask image were suggested to improve GO's robustness against image noise and low texture. Our experimental results on dataset for planar objects with illumination changes and a benchmark dataset confirm the proposed method is robust to illumination variations and capable to deal with the general tracking challenges.
