Spot Identification and Quality Control in Cell-Based Microarrays

Michael Bauer, Blaise Calpe

Cell-based microarrays are being increasingly used as a tool for combinatorial and high throughput screening of cellular microenvironments. Analysis of microarrays requires several steps, including microarray imaging, identification of cell spots, quality ...

Logic and Memory Design Based on Unequal Error Protection for Voltage-scalable, Robust and Adaptive DSP Systems

Georgios Karakonstantis

In this paper, we propose a system level design approach considering voltage over-scaling (VOS) that achieves error resiliency using unequal error protection of different computation elements, while incurring minor quality degradation. Depending on user sp ...

Legged robot locomotion based on free vibration

Nitesh Maheshwari

Behavioral performances of our legged robots are still far behind those of biological systems. Energy efficiency and locomotion velocity of our robots, for example, are orders of magnitude lower than those of animals, and in order to fill the gap, it requi ...

The development of a high-resolution scintillating fiber tracker with silicon photomultiplier readout

Tatsuya Nakada

We present test results from a novel modular scintillating fiber tracker using silicon photomultiplier (SiPM) arrays for readout. The tracker modules are made up from 250 mu m thin scintillating fibers that are arranged in five tightly packed layers on top ...

Optical transmission as a fast and non-destructive tool for determination of ethylene-co-vinyl acetate curing state in photovoltaic modules

Christophe Ballif, Hengyu Li, Laure-Emmanuelle Perret Aebi, Yun Luo

Poly(ethylene-co-vinyl acetate) (EVA) is the primary polymer used for encapsulation of photovoltaic (PV) modules. Its degree of cross-linking (gel content) is taken as a major quality reference. The EVA gel content is normally measured by Soxhlet extractio ...

Monitoring of Steel Lined Pressure Shafts Considering Water-Hammer Wave Signals and Fluid-Structure Interaction

Fadi Hachem

In the past, the safety margin for dynamic water pressure loads in steel-lined pressure tunnels and shafts was considered as acceptable by using conventional design safety factors. Due to high peak energy demands, existing plants are operating nowadays und ...

Design Tradeoffs in Ultra-Low-Power Digital Nano-Scale CMOS

Seyed Armin Tajalli, Yusuf Leblebici

In ultra-low-power (ULP) applications, the supply voltage is generally reduced well below threshold voltage of MOS devices in order to limit dissipation and to control the device leakage current due to the subthreshold channel residual current. However, re ...

Tasting Families of Features for Image Classification

François Fleuret, Charles Dubout

Using multiple families of image features is a very efficient strategy to improve performance in object detection or recognition. However, such a strategy induces multiple challenges for machine learning methods, both from a computational and a statistical ...

Fusing Loop Detector and Probe Vehicle Data to Estimate Travel Time Statistics on Signalized Urban Networks

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

This article presents a methodology that integrates cumulative plots with probe vehicle data for estimation of travel time statistics (average, quartile) on urban networks. The integration reduces relative deviation among the cumulative plots so that the c ...
