Nanostructured Metal

Nanosized gas sensor elements are potentially faster, require lower power, come with a lower limit of detection, operate at lower temperatures, obviate the need for expensive catalysts, are more heat shock resistant and might even come at a lower cost than their macro-counterparts. In the last two decades, there have been important developments in two key areas that might make this promise a reality. First is the development of a variety of very good performing nanostructured metal oxide semiconductors (MOSs), the most commonly used materials for gas sensing; and second are advances in very low power loss miniaturized heater elements. Advanced nano- or micro–nanogas sensors have attracted much attention owing to a variety of possible applications. In this article, we first discuss the mechanism underlying MOS-based gas sensor devices, then we describe the advances that have been made towards MOS nanostructured materials and the progress towards low-power nano- and microheaters. Finally, we attempt to design an ideal nanogas sensor by combining the best nanomaterial strategy with the best heater implementation. In this regard, we end with a discussion of a suspended carbon nanowire-based gas sensor design and the advantages it might offer compared with other more conventional gas sensor devices.

High Turbulence

Fractal grids can be used to design turbulent flows with low power losses and high turbulence intensities for intense yet economic mixing over a region of designed length and location. The introducing circle grid perforated plate is the main aim of this present paper. In this numerical work, we want to ascertain a new approach in turbulence generators on the structure of premixes flames using perforated plate fractal-grids pattern. In this paper, we compared circle grid perforated plate by varies using its diameters, spacing and number of holes on the plate. The result showed good perceptivity of the fractal generated turbulence and the fractal flow physics. The turbulent intensity can be increased by a grid with higher blockage ratio.

In this paper we have introduced a new approach called Clock Gating and Voltage Scaling (CGVS), which is the combination of two existing techniques i.e. Clock gating and Voltage Scaling. Our aim is to design a low power Devnagari Unicode Checker (DUC) using CGVS technique. This design is implemented on Kintex-7 FPGA families, XC7K70T device, -3 speed grade and FBG676 package. From our analysis, it is observed that, with the use of clock gated technique in our target circuit and with the scaling of voltage from 1.0V to 0.1V, we are achieving clock power reduction of 98.98% on 10GHz and 1THz operating frequencies. Under same voltage scaling scheme, there is 6.66%, 10.38%, 10.64% and 10.62% less reduction in IO power, when the target circuit is operating on 1GHz, 10GHz, 100GHz and 1THz operating frequencies.

A new approach to GPS positioning is described in which the post-processing of ultra-short sequences of captured GPS signal data can produce an estimate of receiver location. The algorithm, called ‘FastFix’, needs only 2–4 ms of stored L1-band data sampled at ∼16 MHz. The algorithm uses a least-squares optimization to estimate receiver position and GPS time from measurements of the relative codephase, and Doppler-shift of GNSS satellite signals. A practical application of this algorithm is demonstrated in a small, lightweight, low-power tracking tag that periodically wakes-up, records and stores 4 ms of GPS L1-band signal and returns to a low-power state—reducing power requirements by a factor of ∼10,000 compared to typical GPS devices. Stationary device testing shows a median error of 27.7 m with a small patch antenna. Results from deployment of this tag on adult Royal Albatross show excellent performance, demonstrating lightweight, solar-powered, long-term tracking of these remarkable birds. This work was performed on the GPS system; however, the algorithm is applicable to other GNSS systems.

Impedance Characteristics

In an effort to improve passenger comfort, the automotive industry is evaluating more sophisticated techniques to reduce engine excited frame vibrations. A new approach is to implement hydraulic mounts in a semi-active mode. In this mode, low power actuators are used to change the impedance characteristics of the mount. This paper presents a dynamic model and analysis of the semi-active hydraulic mount. Experimental data confirming the mount model are presented. Finally, results of an experimental study on the implementation of the semi-active mounts on a production automotive vehicle are presented. The study focuses on frame vibration reduction during engine idle. The semi-active hydraulic mounts show improved vibration levels over passive hydraulic mounts in the vehicle application.
