Cloud gaming now makes any computer game playable on a thin client without the previous worries and frustrations about the hardware requirements. It frees players from the need to frequently upgrade their computers as they can now play games that are hosted on remote servers with a broadband Internet connection and a thin client. However, cloud games are(More)
A 3-node lossy source coding problem for a 2-DMS (X<inf>1</inf>,X<inf>2</inf>) is considered. Source nodes 1 and 2 observe X<inf>1</inf> and X<inf>2</inf>, respectively, and each wishes to reconstruct the other source with a prescribed distortion. To achieve these goals, nodes 1 and 2 send descriptions of their sources to relay node 3. The relay node then(More)
We investigate distributed source coding of two correlated sources X and Y where messages are passed to a decoder in a cascade fashion. The encoder of X sends a message at rate R1 to the encoder of Y. The encoder of Y then sends a message to the decoder at rate R<inf>2</inf> based both on Y and on the message it received about X. The decoder's task is to(More)
The large short time-scale variability of renewable energy resources presents significant challenges to the reliable operation of power systems. This variability can be mitigated by deploying fast-ramping generators. However, these generators are costly to operate and produce environmentally harmful emissions. Fast-response energy storage devices, such as(More)
—The high variability of renewable energy is a major obstacle toward its increased penetration. Energy storage can help reduce the power imbalance due to the mismatch between the available renewable power and the load. How much can storage reduce this power imbalance? How much storage is needed to achieve this reduction? This paper presents a simple(More)
— Integrating energy storage into the grid in scenarios with high penetration of renewable resources remains a significant challenge. Recently, Risk Limiting Dispatch (RLD) was proposed as a mechanism that utilizes information and market recourse to reduce reserve capacity requirements, emissions and other system operator objectives. Among other benefits,(More)
The geometric mean decomposition (GMD) transform coder (TC) was recently introduced and was shown to achieve the optimal coding gain without bit loading under the high bit rate assumption. However, the performance of the GMD transform coder is degraded in the low rate case. There are mainly two reasons for this degradation. First, the high bit rate(More)
