W ith the advent of near-equilibrium growth techniques, it is now possible to synthesize virtually any type of crystalline nanostructure. Researchers can exert a fine control over size, shape and surface chemistry to tailor the properties of their nanomaterial to specific applications relevant to energy conversion, sensing, electronics and photonics. Once in a device, these nanostructures are f...

The process of terahertz generation through optical rectification in a nonlinear crystal is modeled using discretized equivalent current sources. The equivalent terahertz sources are distributed in the active volume and computed based on a separately modeled near-infrared pump beam. This approach can be used to define an appropriate excitation for full-wave electromagnetic numerical simulations...

Online algorithms use a different model from what we’ve seen so far: the algorithm does not have the entire input at its beginning, but receives it piece by piece, sequentially, over time. After receiving each piece, the algorithm must immediately make a decision (updating a data structure, buying/selling stocks) which each have an associated cost. Ultimately, the goal of the algorithm is to mi...

| The use of multiple transmitter and receiver antennas allows to transmit multiple signal substreams in parallel and hence to increase communication capacity. In order to distribute the multiple signal substreams over the MIMO channel, linear spacetime codes have been shown to be a convenient way to reach high capacity gains with a reasonable complexity. The space-time codes that have been int...

Exciting recent developments in wireless multiantenna communications have led to designs aiming mainly at one of two objectives: either high-performance by enabling the diversity provided by multi-input multi-output (MIMO) channels or high-rates by capitalizing on space-time multiplexing gains to realize the high capacity of MIMO fading channels. By concatenating a linear complex-field coder (a...

The effects of dough fortification with different amounts of gluten and full fat soya flour on the quality of spaghetti were investigated. Rheological properties of dough, quality and sensory characteristics of spaghetti with different amounts of gluten (8 to 14%) and full fat soya flour (0 to 20%) were evaluated. Fortification caused improvement in some characteristics such as dough stability ...

A broadband Circuit Analogue (CA) absorber using double-circular-loop array is investigated in this paper. A simple equivalent circuit model is presented to accurately analyze this CA absorber. The circuit simulation of the proposed model agrees well with full-wave simulations. Optimization based the equivalent circuit model, is applied to design a single-layer circuit analogue absorber using d...

The present study examined the effect of the geometric parameters of the Rockfill dams on the 2D static analysis of slope stability. In this regard, several numerical models analyzed for eight heights, three slopes of upstream and downstream, three vertical and skewed core thicknesses and four different impounding time stages namely, "End of Construction", "Full Reservoir", "Half Full Reservoir...
