Traditional screening methods for Mild Cognitive Impairment (MCI) face limitations in accessibility and scalability. To address this, we developed validated a speech-based automatic app implementing three speech–language tasks with user-centered design server–client architecture. The integrates automated speech processing SVM classifiers MCI detection. Functionality validation included comparison manual assessment testing real-world settings (n = 12), user engagement evaluated separately...

Aiming at the problems of low data transmission efficiency and uneven energy consumption caused by unreliable link communication in routing process wireless sensor networks, this article designs a game algorithm based on quality. In article, index for evaluating quality is defined first. Then, quality, node residual energy, minimum jump strategy are integrated into utility function to establish model determine best next hop node. Finally, optimal path obtained according analysis existence...

Chinese train control system (CTCS) is one of real-time distributed supervising and systems that have the physical entities needing cooperation to accomplish their local goal, make possible decisions, execute actions, negotiate through communication protocol reach global criterion. For designing CTCS simulation software, hybrid software agent model adapted other developed on basis deliberative reactive concepts we discuss interesting characteristics this model. The proposed method for level...

The is system, coordination achieved by mobile agents, push agents accomplish allocation, pull collect result evaluate them, all these realized via faded information field, system's on-line ability unit autonomy...

Prevention of accidents is extremely difficult in absence present situation analysis, as the aim to identify incident locations and safety deficiency area key work out effective solution.To access feasibility using Geographic Information System (GIS) for mapping with an existing data source vital estimate variation RTAs (Road Traffic Accidents) pattern by interpolating.Generally, accident particulars like location, date, time, sex suspect are included GIS database.Here, Arc (10.2.1) software...

In this paper, we develop a spectrum allocation algorithm for hierarchical cognitive ad hoc networks based on the secondary user (SU) priority. The assures that SUs with higher priority can get more bandwidths, and thus revenue of whole band be maximized. proposed is two-stage scheme, in which licensed between primary users (PUs) acting as CH (CH-SU) implemented first stage, second purchased from owner traded CH-SUs cluster member (CM)-SUs. Performance analysis shows convergence speed...

Different radio access technology vary with communication parameters, such as mobility, coverage and bandwidth etc. Joint Admission Control (JAC) therefore is put forward to make the different Radio Access Networks (RANs) work together. This paper proposes a distributed JAC scheme based on ecology theory in heterogeneous wireless network. It establishes mapping relationship of ecological competition resources management, adopts Gause-Lotka-Volterra (GLV) model predict network traffic. Based...

Accidents and disasters occur frequently worldwide every year, causing relatively serious losses to personnel property. Emergency command halls are a necessary response mechanism in the event of accidents disasters. Traditional emergency methods have problems such as poor convenience, immobility, high cost. By combining advantages strong immersion, good interactivity, portability mobility virtual reality technology new generation artificial intelligence, mobile visualization hall is...
