Networked Infomechanical Systems (NIMS) introduces a new actuation capability for embedded networked sensing. By exploiting a constrained actuation method based on rapidly deployable infrastructure, NIMS suspends a network of wireless mobile and fixed sensor nodes in three-dimensional space. This permits run-time adaptation with variable sensing location,(More)
Monitoring of environmental phenomena with embedded networked sensing confronts the challenges of both unpredictable variability in the spatial distribution of phenomena, coupled with demands for a high spatial sampling rate in three dimensions. For example, low distortion mapping of critical solar radiation properties in forest environments may require(More)
Xeroderma pigmentosum complementation group C and G (XPC, XPG) play important roles in DNA damage repairing machinery. Genetic variations in the XPC and XPG may be associated with increased risk for colorectal carcinoma (CRC). In this study, we evaluated the relation between the XPC Lys939Gln, XPG Asp1104His polymorphisms, and CRC susceptibility in a(More)
In this article, we focus on solving the energy optimization problem for real-time streaming applications on multiprocessor System-on-Chip by combining task-level coarse-grained software pipelining with DVS (Dynamic Voltage Scaling) and DPM (Dynamic Power Management) considering transition overhead, inter-core communication and discrete voltage levels. We(More)
The increasing capacity of NAND flash memory leads to large RAM footprint on address mapping in the Flash Translation Layer (FTL) design. This paper proposes a novel Demand-based block-level Address mapping scheme with two-level Caching mechanism (DAC) for large-scale NAND flash storage systems. The objective is to reduce RAM footprint without sacrificing(More)
The increasing capacity of NAND flash memory leads to large RAM footprint on address mapping in the Flash Translation Layer (FTL) design. The demand-based approach can reduce the RAM footprint, but extra address translation overhead is also introduced which may degrade the system performance. This paper proposes a two-level caching mechanism to selectively(More)
PURPOSE To evaluate the effect of a computer-aided diagnosis (CAD) system on the diagnostic performance of radiologists for the estimation of the malignancy of pulmonary nodules on thin-section helical computed tomographic (CT) scans. MATERIALS AND METHODS The institutional review board approved use of the CT database; informed specific study-related(More)
The paper presents an algebraic approach to functional verification of gate-level, integer arithmetic circuits. It is based on extracting a unique bit-level polynomial function computed by the circuit directly from its gate-level implementation. The method can be used to verify the arithmetic function computed by the circuit against its known specification,(More)
Layout-level gate camouflaging has attracted interest as a countermeasure against reverse engineering of combinational logic. In order to minimize area overhead, typically only a subset of gates in a circuit are camouflaged, and each camouflaged gate layout can implement a few different logic functions. The security of camouflaging relies on the difficulty(More)
OBJECTIVE The purpose of our study was to compare aortic CT angiography performed at a low tube voltage and reduced dose of contrast material with standard-voltage, standard-contrast-dose CT angiography. SUBJECTS AND METHODS We evaluated 74 patients for aortic disease on MDCT angiography (collimation, 16 x 1.5 mm; beam pitch, 0.9). In 36 patients, we used(More)
