Visual Semantic Navigation using Scene Priors

Abstract: How do humans navigate to target objects in novel scenes? Do we use the semantic/functional priors we have built over years to efficiently search and navigate? For example, to search for mugs, we search cabinets near the coffee machine and for fruits we try the fridge. In this work, we focus on incorporating semantic priors in the task of semantic navigation. We propose to use Graph Convolutional Networks for incorporating the prior knowledge into a deep reinforcement learning framework. The agent uses the features from the knowledge graph to predict the actions. For evaluation, we use the AI2-THOR framework. Our experiments show how semantic knowledge improves performance significantly. More importantly, we show improvement in generalization to unseen scenes and/or objects.

Physical electro-thermal model of resistive switching in bi-layered resistance-change memory

Abstract: Tantalum-oxide-based bi-layered resistance-change memories (RRAMs) have recently improved greatly with regard to their memory performances. The formation and rupture of conductive filaments is generally known to be the mechanism that underlies resistive switching. The nature of the filament has been studied intensively and several phenomenological models have consistently predicted the resistance-change behavior. However, a physics-based model that describes a complete bi-layered RRAM structure has not yet been demonstrated. Here, a complete electro-thermal resistive switching model based on the finite element method is proposed. The migration of oxygen vacancies is simulated by the local temperature and electric field derived from carrier continuity and heat equations fully coupled in a 3-D geometry, which considers a complete bi-layered structure that includes the top and bottom electrodes. The proposed model accurately accounts for the set/reset characteristics, which provides an in-depth understanding of the nature of resistive switching.

Semiconductor wafer boat with reduced wafer contact area

Abstract: A boat for semiconductor wafers has reduced contact surface area with the wafer, thereby preventing distortion of the wafer during heating The boat has an upper member; a lower member, a plurality of wafers being loaded between the upper member and the lower member; and a plurality of support members vertically extended between and connecting the upper member to the lower member for supporting the wafers A plurality of slots are successively and horizontally formed in each of the support members, and the peripheral edge of the wafer is inserted therein, wherein a hemisphere-shaped protrusion is formed inside the slot, and the bottom surface of the wafer contacts and is supported by each hemisphere-shaped protrusion at a single contact point

Wireless charging apparatus and method

Abstract: A wireless charging method and apparatus are provided. A non-contact wireless local communication unit performs non-contact wireless local communication for wireless charging authentication through a non-contact wireless local communication antenna. A wireless power receiver receives supply power from a wireless power transmitter by using a resonator resonating on a resonance frequency equal to that of the wireless power transmitter after the wireless charging authentication. A charging controller performs wireless charging by using the supply power received by the wireless power receiver. One or more switches switch between a connection between the non-contact wireless local communication antenna and the non-contact wireless local communication unit, and a connection between the wireless power receiver and the charging controller.
