The development of cluster and parallel computers has increased the popularity of implementing the Monte Carlo (MC) computational method in medical and scientific applications. However, having access to these high-performance systems is not easy and a reasonable size system is not yet able to solve many popular Monte Carlo problems near real-time. The Field Programmable Gate arrays (FPGAs) have been proved to be useful in speeding up the Monte Carlo algorithm since they are able to execute the problem with a high degree of parallelism. As the FPGA and ASIC are being applied for speeding up Monte Carlo simulations as well as for reducing energy consumption, the generation of pseudorandom number (PRN) by hardware becomes one of major developments. The speed in generating the random numbers and the quality of these numbers are main factors in enhancing the performance and accuracy of the method. In this paper, we present the design and implementation of a multistage pipelining-style Mersenne Twister (MT), one of the most widely used pseudorandom number generation method. By implementing the operations in 4 stages, our design is able to achieve throughput of 178 million, 228 million, and 338 million random numbers per second on 0.25 mu m, 0.14 mu m, and 90 nm processes, respectively. In theory, the implementation can be scaled up to 208 stages and so the throughput can be up to 18 billion random numbers per second.

Polarization fading is a phenomenon observed often in BOTDR distributed sensors, which greatly reduces signal-to-noise ratio of the detected signal. We proposed a scheme based on injecting optical pulse probes with orthogonal polarization states, which is generated by a delay Mach-Zehnder interferometer (MZI) composed of two polarization beam splitters (PBS). The principle is analyzed and the effect of reducing polarization fading is demonstrated experimentally. The method uses simple and passive components and is suitable for practical applications.

Amperometric biosensors consisting of oxidase and peroxidase have attracted great attention because of their wide application. The current work demonstrates a novel approach to construct an enzymatic biosensor based on TiO2 nanotube arrays (TiNTs) as a supporting electrode on which Prussian Blue (PB)-an "artificial enzyme peroxidase" and enzyme glucose oxidase (GOx) have been immobilized. For this, PB nanocrystals are deposited onto the nanotube wall photocatalytically using the intrinsic photocatalytical property of TiO2, and the GOx/AuNPs nanobiocomposites are subsequently immobilized into the nanotubes via the electrodeposition of polymer. The resulting electrode exhibits a fast response, wide linear range, and good stability for glucose sensing. The sensitivity of the sensor is as high as 248 mA M-1 cm(-2), and the detection limit is about 3.2 mu M. These findings demonstrate a promising strategy to integrate enzymes and TiNTs, which could provide an analytical access to a large group of enzymes for bioelectrochemical applications including biosensors and biofuel cells.

NAND flash-based solid state Devices (SSD) are widely used in embedded applications because of their low power consumption, high performance, and shock resistant features. However, these devices have non-deterministic response times due to erase-before-write requirements of NAND flash memory. This is a problem for applications that require real-time access to data storage facilities. Recent work has investigated novel RAID-based architectures for highly reliable SSD storage systems, with the host interface, controller, and other facilities such as garbage collectors implemented on an FPGA. The architecture gives high reliability and guarantees of data integrity in a way that protects against the known failure characteristics of flash memory, but at a further expense of timing guarantees. The contribution of this paper is the presentation, design, and analysis of a co-design simulation platform implemented in a PowerPC based FPGA environment that allows us to investigate the timing constraint issues that result from our architecture.

Microsensing is a leading field in technology due to its wide application potential, not only in bio-engineering, but in other fields as well. Microsensors have potentially low-cost manufacturing processes, while a single device type can have various uses, and this consequently helps with the ever-growing need to provide better health conditions in rural parts of the world. Capacitive biosensors detect a change in permittivity (or dielectric constant) of a biological material, usually within a parallel plate capacitor structure which is often implemented with integrated electrodes of an inert metal such as gold or platinum on a microfluidic substrate typically with high dielectric constant. There exist parasitic capacitance components in these capacitive sensors, which have large influence on the capacitive measurement. Therefore, they should be considered for the development of sensitive and accurate sensing devices. An analytical model of a capacitive sensor device is discussed, which accounts for these parasitic factors. The model is validated with a laboratory device of fixed geometry, consisting of two parallel gold electrodes on an alumina (Al2O3) substrate mounted on a glass microscope slide, and with a windowed cover layer of poly-dimethyl-siloxane (PDMS). The thickness of the gold layer is 1 mu m and the electrode spacing is 300 mu m. The alumina substrate has a thickness of 200 mu m, and the high relative permittivity of 11.5 is expected to be a significantly contributing factor to the total device capacitance. The 155 mu m thick PDMS layer is also expected to contribute substantially to the total device capacitance since the relative permittivity for PDMS is 2.7. The wideband impedance analyser evaluation of the laboratory device gives a measurement result of 2pF, which coincides with the model results;while the handheld RLC meter readout of 4pF at a frequency of 10kHz is acceptable within the measurement accuracy of the instrument. This validated model w

In the past few years, various 3D NAND Flash memories have been demonstrated, from device feasibility to chip implementation, to overcome scaling challenges in conventional planar NAND Flash [1-3]. The difficulties include shrinking the NAND cell and increasing manufacturing costs due to quadruple patterning and extreme ultraviolet lithography, motivating the development of the next-generation node beyond 16nm-class NAND Flash [4]. In this paper, as a new 3D memory device with lower manufacturing cost and superior device scalability, we present a true 3D 128Gb 2b/cell vertical-NAND (V-NAND) Flash. The chip accomplishes 50MB/s write throughput with 3K endurance for typical embedded applications such as mobile and personal computer. Also, extended endurance of 35K is achieved with 33MB/s of write throughput for data center and enterprise SSD applications.

This work focusses on the development of a ZnO based piezo-resistive polymer cantilever sensor platform. Two different approaches have been taken, one based on AI-doped ZnO transistor (TFT) embedded in a polymeric micro-cantilever and another with a ZnO nanowire embedded microcantilever. Low Young's modulus of SU-8, low process temperature and high strain sensing capability of ZnO makes this platform an attractive option for sensor applications. For both the approaches, electromechanical and mechanical characterization results are reported in this work.

This paper presents a novel method to achieve large area contact integration for copper(II) oxide (CuO) nanowire array-based hydrogen gas sensors, which provides a simple solution to the ongoing challenge of harvesting nanostructured materials for gas sensing applications. The method presented herein offers six distinct advantages over previous nanostructured gas sensing technologies: (1) convenient electrical access to as-grown, freestanding nanowire arrays, thereby obviating postgrowth thin-film metallization, (2) lithography-free fabrication, (3) usage of large area nanowire arrays to circumvent low yield of single nanowire sensors, (4) reusability of contacts for batch characterization, (5) compatibility with all free-standing arrays grown on electrically conductive substrates, and (6) rapid response and recovery times. The CuO nanowire array-based gas sensors exhibited 5× to 25× increased resistance during operation, and a 20× improvement in recovery time compared to prior works. © 2013 IEEE.
