The efficiency of wireless power transfer (WPT) can be enhanced considerably by using a metamaterial with appropriate electromagnetic parameters. For safety and applicability concerns, deep sub-wavelength metamaterials with low operating frequencies and small sizes are required in WPT. This paper proposes a hybrid search method for the optimization design of planar spiral metamaterials which are widely...
The aim of this note is to study single machine scheduling problems with resource dependent release times. Each job starts as soon as it is released and release cost will be generated if its actual release time deviates from the initial release time. The objective is determining a sequence of jobs in addition to their release times concurrently, in order that weighted release cost, makespan and total...
Existing de-noising algorithm's de-noising result is not satisfactory. In response to this phenomenon, this paper presents an improved soft threshold de-noising algorithm based on sensitive characteristics of the human visual. According to the inherent characteristics of the human eye's visual, we improved soft threshold de-noising algorithm. After simulation experiment, the experimental results conform...
Power system static security assessment is one of the most important problems which relate power system secure-stable performance. Static security can be rapidly assessed using the artificial intelligence technology. This paper compares the advantages and disadvantages of Artificial Neural Network (ANN) and Support Vector Machines (SVM) and then selects the SVM algorithm. A new multi-classification...
Since Volker Strassen proposed a recursive matrix multiplication algorithm reducing the time complexity to n2.81 in 1968, many scholars have done a lot of research on this basis. In recent years, researchers have proposed using computer algorithms to solve fast matrix multiplication problem. They have found Strassen's algorithm or other algorithms that have the same time complexity as Strassen algorithm...
RoboCup Keepaway is one of the most challenging multiagent systems (MAS) where a team of keepers tries to keep the ball away from the team of takers. Most of current works concentrate on the learning of keeper, not the learning of taker, which is also a great challenge to the application of reinforcement learning (RL). In this paper, we propose a task named takeaway for takers and study the learning...
This paper presents a fast wireless anti-collision algorithm for radiofrequency identification (RFID) systems. The proposed algorithm introduces a new kind of inquiry round to gain the request prefixes from tags. It also has the advantages of jumping and dynamic searching algorithm (JDS) and prefix-randomized query-tree protocol (PRQT). Analysis and simulation results show that the proposed algorithm...
