Autonomous soccer robots should recognize the environment from the captured image from a video camera and plan to proper behavior. Furthermore, when some robots play cooperatively, communication system between robots is important inputs. We choose simple vision and actuator system, then the gap between the real world and simulation environment are small. Our research target is to accomplish multiagent system using reinforcement learning.

The increasing demand for more efficient, compact and reliable power conversion in modern electric vehicles has led to the fast adoption of silicon carbide (SiC) inverters. While SiC devices bring dramatic gains in power density and system efficiency compared to their silicon counterparts, the technology is still underperforming due to aggravated chip-package interactions. On the electrical side, greater switching speeds result in increased dv/dts and di/dts, which, when coupled with the package parasitics result in increased overcurrent and voltage spikes and oscillation, aggravated noise and risks of electrical discharge machining failures. To address this challenge, a new leadframe-based package architecture with die stacking is proposed in this paper. While it provides output capacitance decoupling as well as a low-inductive current flow in the power module, die stacking may lead to thermal densification and subsequent reliability concerns that need to be considered in the design phase. To mitigate these multi-physics trade-offs, a novel machine-learning-based algorithm is used to optimize the package layout for best electrical, thermal and reliability performances and power density.

This paper presents an ontology-based approach for automatic decomposition of learning objects (LOs) into reusable content units, and dynamic reassembly of such units into personalized learning content. To test our approach we developed TANGRAM, an integrated learning environment for the domain of intelligent Information Systems. Relying on a number of ontologies, TANGRAM allows decomposition of LOs into smaller content units, which can be later assembled into new LOs personalized to the user's domain knowledge, preferences, and learning styles. The focus of the presentation is on the ontologies themselves, in the context of user modeling and personalization. Furthermore, the paper presents the algorithm we apply to dynamically assemble content units into personalized learning content. We also discuss our experiences with dynamic content generation and point out directions for future work.

In this article, we formulate a new variant of the problem of finding a maximum clique of minimum weight in a graph applied to the detection and resolution of conflicts between aircraft. The innovation of the model relies on the cost structure: the cost of the vertices cannot be determined a priori, since they depend on the vertices in the clique. We apply this formulation to the resolution of conflicts between aircraft by building a graph whose vertices correpond to a set of maneuvers and whose edges link conflict-free maneuvers. A maximum clique of minimal weight yields a conflict-free situation involving all aircraft and minimizing the costs induced. We solve the problem as a mixed integer linear program. Simulations on a benchmark of complex instances highlight computational times smaller than 20 seconds for situations involving up to 20 aircraft.

The Internet-of-Things (IoT) is an inevitable technology that is going to be transform the automation process by massively connected communicating devices that has limited resources. However, in order to carry out fault tolerant communication in IoT, it is essential to ensure that each IoT nodes should be able to perform seamless communication in a defined level of restricted bandwidth along with better energy retention capability. Review of existing solution shows that it offers solution to highly narrowed scale of problem. Therefore, the proposed system offers a novel framework which uses scheduling approaches in order to optimize the bandwidth utilization as well as retain maximum amount of residual energy among the communicating IoT nodes. The simulation of the model shows that proposed scheme offers better bandwidth management and efficient energy conservation in contrast to existing system.
