In this paper, we present a novel signal processing method for video synthetic aperture radar (ViSAR) systems, which are suitable for operation in unmanned aerial vehicle (UAV) environments. The technique improves aspects of the system’s performance, such as the frame rate and image size of the synthetic aperture radar (SAR) video. The new ViSAR system is based on a frequency-modulated continuo...

High energy consumption becomes an urgent problem in cloud datacenters. Based on virtualization technologies, the pay-as-you-go resource provision paradigm has become a trend. Specifically, Virtual Machine (VM) is the basic resource unit in data center for resource migration and provisioning. Many researches have been devoted to improve datacenter resource utilization and reduce power consumpti...

Energy efficiency has become an important measurement of scheduling algorithm for private cloud. The challenge is trade-off between minimizing of energy consumption and satisfying Quality of Service (QoS) (e.g. performance or resource availability on time for reservation request). We consider resource needs in context of a private cloud system to provide resources for applications in teaching a...

High levels of arsenic in groundwater and drinking water represent a major health problem worldwide. Drinking arsenic-contaminated groundwater is a likely cause of blackfoot disease (BFD) in Taiwan, but mechanisms controlling the mobilization of arsenic present at elevated concentrations within aquifers remain understudied. Microcosm experiments using sediments from arsenic contaminated shallow...

The IETF Transparent Interconnection of Lots of Links (TRILL) protocol supports arbitrary link technologies between TRILL switches, including point-to-point links and multi-access Local Area Network (LAN) links that can have multiple TRILL switches and end stations attached. TRILL uses Intermediate System to Intermediate System (IS-IS) routing. This document specifies the establishment, reporti...

The bin packing problem is a well-studied combinatorial NP-hard problem. In the bin packing problem, a sequence of items are packed into bins, the packed items in a bin do not overlap. The objective is to minimize the number of used bins. The size of each item should be no more than the size of a bin. (Zhang, 2011) The algorithms can be divided into two categories: offline algorithm, requiring ...

Regulation of iron uptake and utilization is critical for bacterial growth and for prevention of iron toxicity. In many bacterial species, this regulation depends on the iron-responsive master regulator Fur. In this study we report the effects of iron and Fur on gene expression in Vibrio cholerae. We show that Fur has both positive and negative regulatory functions, and we demonstrate Fur-indep...
