Data center cooling system
Approaches presented herein enable cooling a data center with a cooling system having a relatively high coolant temperature. This cooling system is controlled by a building management system and includes piping through which coolant flows, an air cooling unit in thermal contact with the coolant, and a chiller to cool the coolant to a temperature between 18 and 22 degrees Celsius as instructed by the building management system. The building management system uses a chiller controller to vary the chilling of coolant within a range of 18-22 degrees Celsius, thereby controlling the air temperature within the data center to within a required temperature range. Because the building management system maintains the coolant temperature to 18-22 degrees Celsius, the cooling system can be simplified by excluding typical cooling system components such as variable flow control valves and their controllers. This simplification decreases the need for maintenance and reduces operating cost. |

Method for high performance on-demand video transcoding
Video streams, either in form of on-demand streaming or live streaming, usually have to be transcoded based on the characteristics of clients' devices. Transcoding is a computationally expensive and time-consuming operation; therefore, streaming service providers currently store numerous transcoded versions of the same video to serve different types of client devices. Due to the expense of maintaining and upgrading storage and computing infrastructures, many streaming service providers recently are becoming reliant on cloud services. However, the challenge in utilizing cloud services for video transcoding is how to deploy cloud resources in a cost-efficient manner without any major impact on the quality of video streams. To address this challenge, in this paper, the Cloud-based Video Streaming Service (CVSS) architecture is disclosed to transcode video streams in an on-demand manner. The architecture provides a platform for streaming service providers to utilize cloud resources in a cost-efficient manner and with respect to the Quality of Service (QoS) demands of video streams. In particular, the architecture includes a QoS-aware scheduling method to efficiently map video streams to cloud resources, and a cost-aware dynamic (i.e., elastic) resource provisioning policy that adapts the resource acquisition with respect to the video streaming QoS demands. Simulation results based on realistic cloud traces and with various workload conditions, demonstrate that the CVSS architecture can satisfy video streaming QoS demands and reduces the incurred cost of stream providers up to 70%. |

Provided are methods and systems for improving the intelligibility of speech in a noisy environment.

Multi-ring coupled ring oscillator with improved phase noise
The disclosure of the present application presents a multiple-ring coupled ring oscillator design that employs multiple-ring coupling to achieve improved phase noise by minimizing noise injection from tail current and adjacent rings, while providing additional output phases for multiphase signal generation. In one non-limiting exemplary prototype embodiment, a 1.5 GHz triple-ring coupled ring oscillator achieved measured phase noise of −110.5 dBc/Hz at 1 MHz offset, demonstrating phase noise reduction of 7 dB compared with its single-ring oscillator counterpart. The MROs couple multiple rings with proper phase shifting to achieve improved phase noise. Common source coupling benefits from tail current noise reduction, and introducing phase delays in the coupling paths minimizes noise coupling from the adjacent cores. The overall effect leads to improved phase noise performance as demonstrated in quadrature voltage controlled VCO designs. The concept is applied to ring oscillator designs and, as stated previously, demonstrates a triple-ring coupled ring oscillator with phase noise improvement. The design of the present application also triples the number of output phases compared to its single ring oscillator counterpart. The application of injection-locked PLL by using proposed multiple ring coupled ring oscillator achieves the same low phase noise as traditional IL-PLL does while lowering the reference spur at auxiliary ring's output. In another non-limiting exemplary embodiment, the proposed IL-PLL consumes 13.5 mW of power, while achieving in-band phase noise of −120.97 dBc/Hz at 1 MHz offset at 1.1 GHz output frequency. |
