In this paper, a new modeling approach for Dielectrophoresis (DEP) based particle manipulation is presented. The proposed method fulfills missing links in finite element modeling between the multiphysic simulation and the biological behavior. This technique is amongst the first steps to develop a more complex platform covering several types of manipulations such as magnetophoresis and optics. T...

An efficient algorithm that dynamically calculates all possible ray paths in outdoor (macroand micro-cells and land mobile satellite, LMS) and indoor environments is presented in this paper. The algorithm is based on the sweep line technique. Additionally a quadtree (bounding box [1]) division of the study environment is used to reduce search time. For indoor and microcellular environments wall...

Computational studies have recently gained significant interest in engineering applications for the virtual monitoring of bone pathologies such as osteoporosis and fracture healing. Several authors have investigated numerically the role of quantitative ultrasound as a diagnostic and monitoring tool of the fracture healing process since ultrasonic techniques are non-invasive and non-ionizing mea...

While the formation of cracks is often stochastic and considered undesirable, controlled fracture would enable rapid and low cost manufacture of micro/nanostructures. Here, we report a propagation-controlled technique to guide fracture of thin films supported on soft substrates to create crack arrays with highly controlled periodicity. Precision crack patterns are obtained by the use of strateg...

Photonic circuits based on silicon wire waveguides have attracted significant interest in recent years. They allow strong confinement of light with moderately low propagation losses. Moreover, the high thermo-optical coefficient of silicon and the small device size in silicon photonics allow for micro-heaters induced trimming, tuning, and switching with relatively low power. In this paper, we r...

Language change can be understood as an evolutionary process. Language change occurs at two different timescales, corresponding to the two steps of the evolutionary process. The first timescale is very short, namely, the production of an utterance: this is where linguistic structures are replicated and language variation is generated. The second timescale is (or can be) very long, namely, the p...

MTCMOS is an effective circuit level technique which has multiple threshold voltages in order to optimize delay and power. Low threshold voltage MOSFETs enhance the speed performance, while the high threshold voltages MOSFETs minimize the static leakage power. The above technique is adopted in parallel multiplier with level shifter interface which gives supply voltage for MTCMOS transistors. By...

Base station (BS) cooperation technologies are expected to improve user throughput at the cell edges in a cellular system [1]-[3]. Since the performance of a BS cooperation method depends on the condition of the propagation channel, especially the difference in the received signal strengths from surrounding BSs, it is important to investigate the transitions of the signal strengths at a mobile ...

Two-phase micro-pipeline asynchronous modules show faster performance than common fourphase control systems, but the conventional systems with multi-port modules normally suffer from longer signal paths on stacked C-elements. NOR-based control schemes provide an alternative solution to problems such as propagation delay. This paper presents two modified designs from the common two-phase and alt...

Using a high-speed camera, we follow the propagation of the detachment front during the peeling of an adhesive tape from a flat surface. In a given range of peeling velocity, this front displays a multiscale unstable dynamics, entangling two well-separated spatiotemporal scales, which correspond to microscopic and macroscopic dynamical stick-slip instabilities. While the periodic release of the...
