Recently, many researchers have used graph theory to study the aberrant brain functions in mental disorders. However, the characteristics of the brain functional network in attention deficit hyperactivity disorder (ADHD) are still largely unexplored. In this study, blood oxygen level-dependence (BOLD) functional magnetic resonance images (fMRI) were employed to construct brain functional networks...
This discussion paper presents an initial blueprint and viability analysis for implementing a location-based service pilot in Guangzhou, China, using a Finnish company named Nokia as a specific case example. Although many technological, political, and economic issues still remain open, our initial findings were supportive of the viability of implementing the desired pilot.
For resistance furnace has a large inertia, delay, uncertainty caused by the system outside interference and ctime-varying of model parameters characteristics, a practical linear reduced-order ADRC with parameters tuning method is proposed. This new method employs a linear reduced-order model with ascending curve method and based on PID parameters tuning. Hardware circuit designs combine with linear...
We show theoretically that Bragg stopband and defect resonance mode can be achieved and dynamically tuned over a wide wavelength range by a small change in Fermi energy level of graphene, in graphene plasmonic waveguide structures.
As much of the web information nowadays is published by roaming mobile users, and these mobile users may get services from various foreign agents, security, privacy and authentication are important for the roaming service in global mobility networks. In 2011, Chen et al. proposed a lightweight and provably secure user authentication scheme with anonymity for roaming service. We first show that their...
In this paper, we study traffic flow on a highway with three consecutive on-ramps by using the Nagel-Schreckenberg model, which is a generalization of our previous work concerning with highway with two ramps. We still focus on how to improve the system capacity by assigning traffic demand to the three ramps. It is shown that when all ramps are in free flow and the main road upstream of the ramps is...
There have been a number of research projects which have addressed depression, the focus often being on aspects of pharmacology and psychology. Relatively few of the investigations have tried to integrate depression and the related issues into a pervasive depression prevention system incorporating user-centered design. In this paper we propose an approach to provide relief for a user(s) depression...
A network traffic system can be tuned by three factors: (i) the topology of underlying infrastructure; (ii) the distribution of traffic resources; (iii) the routing strategy. In this paper, we propose a model to study the optimization of network capacity based on complex network theory. We study the optimization method of network traffic in several situations corresponding to the real cases. The model...
