A new asynchronous pipeline scheme (called LPHC), and two new pipelined asynchronous adder implementations, are introduced for high-throughput applications such as DSP’s for multimedia processing. The pipeline scheme is targeted to dynamic datapaths. A novelty of the approach is that it uses decoupled control for pull-up and pull-down stacks. The adders are pipelined at the gate-level and achie...

In this paper, the dynamic characteristics of clamped-clamped silicon microbeam subjected to electrostatic excitation and mechanical shock is investigated. The Euler-Bernoulli beam model based on the modified couple stress theory with von Kármán geometric non-linearity is utilized in theoretical formulation. Afterwards, squeeze-film damping effects of microstructures for small amplitude vibrati...

A MoC with push and pull processing 2 A MoC with push and pull processing 3 Abstract This report studies a model of computation (MoC) that supports Push-Pull communication between software components. Push represents message transfer that is initiated by the producer. On the contrast, Pull represents message transfer that is initiated by the consumer. Push-Pull messaging mechanisms have been us...

the static pull-in instability of beam-type micro-electromechanical systems is theoretically investigated. two engineering cases including cantilever and double cantilever micro-beam are considered. considering the mid-plane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent euler-bernoulli beam model is used based on a modified couple stress theory, c...

The treatment of posterior segment disorders the eye requires therapeutic strategies to achieve drug effects over prolonged times. Innovative colloidal delivery systems can be designed deliver drugs retina and prolong their intravitreal permanence. In order exploit pullulan (Pull) as polymeric carrier for delivery, derivatives hydrophobic model molecule rhodamine B (RhB) were conjugated backbon...

In this paper we demonstrate highly linear Mach-Zehnder interferometer modulators utilizing heterogeneous integration on a Si substrate (HS-MZM). A record high dynamic range was achieved for silicon devices, obtained using hybrid III-V/Si phase modulation sections and single drive push-pull operation, demonstrating a spurious free dynamic range (SFDR) of 112 dB∙Hz2/3 at 10 GHz, compa...

The increasing growth of wireless access networks, proliferation of the Internet and gradual deployment of broadband networks has already given birth to a set of information-centric applications based on data transmission. Efficient scheduling techniques are necessary to endow these applications with advanced data processing capability. Broadly all data transmission applications are divided int...

Client-server databases that require query results to be up-to-date despite storing data that changes dynamically suffer from heavy communication costs. Client-side caching can help mitigate these costs, particularly when individual PUSH-PULL decisions are made for the different semantic regions in the data space. In the PUSH regions the server notifies the client about updates, and in the PULL...
