The problem of robust fault-tolerant control for networked control systems (NCSs) is discussed in this paper. The uncertainty of network-induced delays is converted to the uncertainty of the parameter matrix, and in order to eliminate the effect of the asynchronism the states are transformed into the augmented states. Based on Lyapunov stability theory and(More)
Stroke is a leading cause of death and disability, affecting millions of people worldwide with almost 80% of them as ischemic stroke and understanding the multiple mechanisms underlying cerebral ischemia is essential for development of effective treatments. To understand metabolic changes induced by focal brain ischemia, we conducted a comparative analysis(More)
BACKGROUND The Short Musculoskeletal Function Assessment (SMFA) questionnaire is one of the most commonly used scales to evaluate functional status and quality of life (QOL) of patients with a broad range of musculoskeletal disorders. However, a Chinese version of the SMFA questionnaire for the psychometric properties of skeletal muscle injury patients in(More)
Firstly, this paper predicts the volume of logistics in Ningbo Port with the two methods of improved BP neural network and gray model, and introduces combined forecast methods on the basic of researching on those two forecast methods. Theories and practices have shown that combined forecast model are more accurate than single forecast model, and can enhance(More)
The development of reference values of trace elements is recognized as a fundamental prerequisite for the assessment of trace element nutritional status and health risks. In this study, a total of 1400 pregnant women aged 27.0 ± 4.5 years were randomly selected from the China Nutrition and Health Survey 2010-2012 (CNHS 2010-2012). The concentrations of 14(More)
BACKGROUND As the population ages, the proportion of elderly patients with glioblastomas has increased. Recently, many researchers have focused on the treatments available to and prognoses in elderly patients with glioblastomas. METHODS We conducted a retrospective study of glioblastoma patients aged 60 years old or older who were treated at the(More)
Mode-spectrum matrix is introduced to describe the multi-dimensional resources in packet optical transport networks (POTN) with multi-mode fibers (MMF), based on which a novel shared backup path protection algorithm is proposed to optimize the allocation of optical resource during virtual link mapping (VLM) in packet optical transport networks.
Spectrum defragmentation in elastic optical networks can be considered to conduct rearrangement of the deployed lightpaths, which can achieve some optimization objectives including lower blocking probability, higher spectrum utilization, minimum connection disruption and so on. The emergence of software-defined networks provides an effective way to(More)
An auxiliary graph (AG) is designed to address traffic grooming under dynamic traffic scenario in spatial division multiplexing enabled elastic optical networks (SDM-EON). Various traffic grooming policies are achieved by adjusting the edge weights of AG, and evaluated through simulation in terms of spectrum efficiency and inter-core crosstalk. Numeric(More)
