Graphics processing unit (GPU) has been applied successfully in many scientific computing realms due to its superior performances on float-pointing calculation and memory bandwidth, great potential power system applications. The N-1 static security analysis (SSA) appears be a candidate application which massive alternating current flow (ACPF) problems need solved. However, when applying existing GPU-accelerated algorithms solve SSA problem, the degree of parallelism is limited because...

According to the development and research of sliding mode variable structure control (SMVSC) in recent years. This paper mainly reviews applications some popular (SMC), such as adaptive SMC, discrete-time system fuzzy neural network SMC. With switched (SS), scholars can deal with complex changeable more effectively by combining SMC SS, so improve efficiency stability system. The theoretical combined predictive SS uncertainty are also becoming attractive. purpose this is analyze organize...

Abstract Magnetic resonance (MR) imaging is advantageous because it concurrently provides anatomic, functional, and molecular information. MR can combine the high spatial resolution of this established clinical modality with profiling in vivo. However, as a result intrinsically low sensitivity imaging, local concentrations biological targets are required to generate discernable contrast. We hypothesize that prostate‐specific membrane antigen (PSMA), an attractive target for therapy prostate...

The joint anti-accident exercises in multi-level dispatching and control systems using dispatcher training simulator (DTS)are distributed interactive simulation. It has many problems, such as wide cross domain, tedious preparation, complex communication etc. Based on model management service, DTS of multi-area becomes reality. is an effective way to study the system based multi-agent theory. In this paper, application agent divided into three stages. first stage part-role agent. second...

In the integrated mode of power grid dispatching and control centralized monitoring, dispatchers need to prioritize events, determine fault types propose solutions timely accurately, which puts forward high requirements on operational ability response level dispatchers. To relieve working pressure dispatchers, a ontology knowledge base based theory rules is built in this paper, realizes information search query with conciseness, preciseness, rapidity. The instantiation can provide...

Large scale wind power integration and demand response has brought uncertainty to both source load side of system which brings new challenges the evaluation available transfer capability (ATC) system. In order evaluate ATC under source-load more accurately, a probability method considering is proposed in this paper. Firstly, characterized by Gaussian mixture model (GMM)-based method. Then calculation existing commitments (ETC) done optimal flow (OPF)-based taken into consideration, ensure...

Estuaries are commonly recognized as a major source of greenhouse gases due to the massive anthropogenic input organic matter and nutrients, which is associated with highly active microbial assemblages. However, combined effects natural factors their relative contributions estuarine gas emissions not well understood, particularly at confluence fresh water seawater. In this study, biweekly sampling was conducted from November 2021 January 2024 main outlet Pearl River in south China,...

Oyster aquaculture helps mitigate coastal eutrophication by assimilating organic nitrogen for biomass and denitrification in both the oyster digestive tract sediment below. Efforts are needed quantitative assessment of oysters’ multiple removal pathways at large-scale sites, especially bodies, which has been much less quantified among these pathways. This study takes a subtropical estuary (Shenzhen Bay South China) as testbed to conduct laboratory rearing experiments field investigation. The...

We present a new hybrid channel allocation method which includes both the nominal and dynamic allocation. More efficient usage is achieved through co-channel distance minimization. To further improve performance, there no division of fixed groups. The pool all channels in system.

After the outbreak of COVID-19, retail industry has been hit unprecedentedly in all aspects. Obviously, traditional business model is no longer suitable for today's market environment. This research takes retailer from Guandong, China, Urban Neighbourhood Ltd as a case study company to analyze overall situation retailers context long-term COVID-19 and identify by using canvas. adopts Business Process Management (BPM) Lifecycle main methodology. Data collection methods include conversation,...

In this paper a new hybrid channel allocation method is presented, which focuses on both nominal and dynamic allocation. Copyright © 2000 John Wiley & Sons, Ltd.
