Remote health monitoring (RHM) has emerged as a solution to help reduce the cost burden of unhealthy lifestyles and aging populations. Enhancing compliance to prescribed medical regimens is an essential challenge to many systems, even those using smartphone technology. In this paper, we provide a technique to improve smartphone battery consumption and examine the effects of smartphone battery lifetime...
With the development of smart grid and the increasing penetration of intermittent generation such as wind and solar, transmission network must be operated more effectively and flexible. Transmission switching has been explored in some literature as an effective mean to reduce dispatch cost. In this paper, based on dc optimal power flow we formulate this problem as a bilevel programming problem. The...
Based on the distributed energy technology, MicroGrid has caused wide attention. It is of great significance to solve the problem of electricity generation in rural areas by establishing an independent MicroGrid system, which mainly consists of solar energy and wind energy. It becomes crucial to find a way to optimize the structure of MicroGrid according to various energy situations. Based on the...
Due to the dramatic increase in design complexity, verifying the functional correctness of a circuit is becoming more difficult. Therefore, bugs may escape all verification efforts and be detected after tape-out. While most existing solutions focus on fixing the problem on the hardware, in this work we propose a different methodology that tries to generate constraints which can be used to mask the...
This paper presents a new approach to the problem of system decomposition in a power system state estimation problem. The complexity of power systems is growing thus challenging the way measurements for state estimation are traditionally managed. Following a previous experience in defining a decentralized solution for state estimation, the authors here propose a procedure to automatically identify...
We consider a mutual insurance system whose reserve is determined by a Brownian motion. The controller tries to minimize the total cost by increase or reduce the reserve instantly. Both cases of zero and positive fixed cost are investigated. By applying the theory of stochastic control with QVI approach, we make the connection between singular control and impulse control. The procedures to solve these...
In those problems dealing with linguistic information and multiple sources of information may happen that the sources involved have different degree of knowledge about the problem and could be suitable and necessary the use of different linguistic term sets with different granularity defining a multi-granular linguistic context. Different approaches have been presented to deal with this type of context,...
