With the process of China's entering a serious aging society, it generally becomes one of the problems for people caring as elderly falls frequently. Thus, it is necessary for us find a way that the old people get help timely when it happened. On studies related to falls in outdoors currently, popular methods are on Computer Vision and Inertial Sensor. The problems of these researches are focus on...
Nonlinear sparse sensing (NSS) techniques have been adopted for realizing compressive sensing (CS) in many applications such as Radar imaging and sparse channel estimation. Unlike the NSS, in this paper, we propose an adaptive sparse sensing (ASS) approach using reweighted zero-attracting normalized least mean fourth (RZA-NLMF) algorithm which depends on several given parameters, i.e., reweighted...
Spatial resolution of Distributed optical fiber temperature sensor (DTS) system has a great effect on the applications. The principle of spatial resolution is briefly introduced in this paper. An experiment system is presented to test the value of spatial resolution. A method to compensate the spatial resolution while the value has not meet the requirement is proposed and been proved effective to...
Cloud endows application with the ability of controlling runtime environment dynamically. Comparing with traditional one, Cloud APPlication (CAPP) could be more dynamic and autonomic. However, enabling CAPP to handle problems such as performance optimization or resources utility efficiency improvement in complex cloud environment with existing technologies is difficult and problematic. To address...
This paper addresses the optimal filtering problem for a kind of local strongly coupled systems. We introduce a local strongly coupled system with communication between the nodes. Applying the standard kalman filter design procedures to such systems is difficult because of transmission delay and intermittent communication. By using the stochastic theory and state augmentation technique, we present...
The optimization and selection procedure of logistics center facilities layout projects has an important status in the logistics system layout and planning. Aiming at the deficiencies existing in the logistics center facilities layout projects optimization and selection, a new optimization frame was developed. Based on the analysis to the recent relevant studies, the evaluation index system for logistics...
Considering alternative resources for operations, requirement of multiple resources to process an operation and a jobpsilas batch size greater than one in the real manufacturing environment, a study is made on the batch splitting scheduling problem with bounded batch sizes under multiple-resource constraints, based on the objective to minimize the maximum completion time. A genetic algorithm which...
Hierarchical identity-based encryption (HIBE) is a generalization of IBE that mirrors an organizational hierarchy, which consists of a root private key generator (PKG), domain PKGs and users. In a traditional HIBE system, users retrieve private keys from their domain PKGs, while domain PKGs request domain secret keys from the root PKG. What's more, the manager of each private key is a single one....
