Abstract:
The Cyclic Prefix (CP) technique is widely used in Orthogonal Frequency Division Multiplexing (OFDM) systems. A CP of length greater than the channel order guarantees the orthogonality of the consecutive OFDM symbols. Therefore, the effects of Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI) are cancelled. On the other hand, CP reduces the transmission efficiency.Conventional OFDM systems use constant length CP. For time varying channels, CP length may become shorter than channel order resulting in considerable loss in orthogonality and performance degradation. Otherwise, w

Abstract:
Channel confluences happen commonly in water transport networks and natural rivers. Utilizing a 3D CFD code, a series of numerical simulations were performed using a large eddy simulation turbulence model to investigate the effect of the variations in tributary channel width and the transverse geometrical shape of the main channel on the flow parameters and vertical structure in a T-shape confluence. The code was calibrated using the experimental data from the literature. Flow parameters were considered in ratios of tributary width to the main channel width in trapezoidal and rectangular chann

Sound absorption below 1000 Hz has been extremely difficult through traditional barriers and absorbers, but it is required for noise control of appliances and machineries. Existing passive acoustic metamaterials attenuate low-frequency noise but with narrow bandwidths and bulky sizes. Hence, this paper proposes an acoustic metamaterial with enclosed symmetrical labyrinthine air channels and two micro-slits (configuration 1, identical slits; configuration 2, unequal length slits) at the end channels. Its theoretical model is established by acoustic impedance analysis using electro-acoustic anal

Abstract:
Wireless broadband transmission channels usually have time-domain-sparse properties, and the reconstruction of these channels using a greedy search-based orthogonal matching pursuit (OMP) algorithm can effectively improve channel estimation performance while decreasing the length of the reference signal. In this research, the improved OMP and SOMP algorithms for compressed-sensing (CS)-based channel estimation are proposed for single-carrier frequency domain equalization (SC-FDE) systems, which, in comparison with conventional algorithms, calculate the path gain after obtaining the path delay

The following correlation is established: the specific force is increased and the exergy of the flow is used better with decreasing length of the zone of energy supply and with decreasing of distance betwee

The fractal tree-like branched network is an effective channel design structure to reduce the hydraulic resistance as compared with the conventional parallel channel network. In order for a laminar flow to achieve minimum hydraulic resistance, it is believed that the optimal fractal tree-like channel network obeys the well-accepted Murray’s law of βm = N −1/3 (βm is the optimal diameter ratio between the daughter channel and the parent channel and N is the branching number at every level), which is obtained under the assumption of no-slip conditions at the channel wall–liquid interface.

This work provides evidence that channels in directionally solidified hypoeutectic Pb-Sn alloys nucleate at the dendrite tips.

With D the diffusion coefficient in the melt and V the solidification rate, the thickness of this layer, and therefore the stability of the systems studied, is shown to be a function

Numerical calculations were performed over a variety of two-dimensional rib roughness configurations in which the ratio of flow depth to roughness height was varied from 1.1 to 40. Periodically fully developed flow was achieved by employing periodic boundary conditions and the effect of turbulence was accounted for by a two-layer model. These calculations were used to test the hypothesis that any rough wall resistance may be reduced to an equivalent wall shear stress located on a plane wall. The position of the plane wall is determined by a novel method of prediction obtained by consideration

Abstract:
AbstractThe soil nutrients, main agronomic indexes, and key yield factors during the maize growth period were studied by using a nutrient expert system to recommend optimal fertilization. The results showed that the fertilizer application had a significant impact on the growth and yield formation of maize, especially the N fertilizer application. N deficiency in maize seriously affected the yield and its component factors, while P and K deficiency had no significant effect on decreasing maize yield. The optimized fertilization treatment (NE) significantly reduced the bald tip length and increased the ear length and the yield of maize by 10.2% compared with the conventional fertilization treatment (FP). NE significantly increased the utilization rate of N, P, and K in maize, which was 20.1%, 12.4%, and 45.4% higher than that of FP. The trend of fertilizer N deficiency was opposite to NE, but P and K deficiency were not obvious. Compared with FP, soil organic matter of NE did not change significantly, and the pH value was increased. Nitrate nitrogen and ammonium nitrogen were decreased by 51.9% and 3.9%, respectively. A significant correlation between maize yield and alkali hydrolyzed nitrogen, organic matter. In conclusion, the optimized fertilization treatment had obvious effects on the growth indicators and yield components of maize, improving the fertilizer utilization rate, and providing technical support for rational fertilization of maize.

Abstract The effect of rising and falling stress intensity factor (K) on the SCC growth rates of stainless steel and nickel alloys has been studied in high temperature water.

The majority of SCC problems develop adjacent to welds, which have a complex residual stress profile vs. wall thickness. This, coupled with the dependence of K on crack length, causes K to change as the crack grows, not per se with time (t). Th

Abstract:
Experiments have been conducted into the freezing of water flow and the aqueous solution flow of winter flounder antifreeze protein in a micro-channel of 0.15mm in height, 1.2mm in width and 21mm in length. The local temperature is measured with a sheathed thermocouple of 0.1mm in diameter. Nearly flat interfaces, parallel to the cooling sidewall of the channel, are observed in the case of pure water regardless of flow rate. On the other hand, serrated interfaces are observed in the case of protein solution flow regardless of flow rate. The decreasing rate of the temperature changes when the i

Abstract:
Add-drop filters are key components for WDM communication systems. Filters with flat passbands, which can separate channels spaced by 100 GHz, are needed to allow many devices to be concatenated without decreasing the available channel bandwidth significantly. A Mach- Zehnder Interferometer (MZI) with UV-induced gratings realized using planar waveguides [1] is an attractive architecture for creating an add-drop filter (see Fig. 1a). To increase the number of devices which can be fabricated on a common substrate, it is desirable to make the overall device as short as possible; however, requirem

Abstract:
The pressure drop of convective boiling flow may be reduced by extracting vapor locally since the entire generated vapor does not have to travel through the entire channel length. In this study, the theoretical model was developed to simulate a convective boiling flow through a fractal-like branching microchannel network with vapor extraction. The fractal-like branching microchannel network has a porous membrane forming one wall of the channels. Vapor extraction occurs by applying a vacuum across the membrane. Sample predictive local conditions and global results are presented and discussed. T

3D-IC is getting increasingly attractive, as it improves speed and frequency, and reduces power consumption, noise and latency. However, three dimension (3D) integration technologies bring a new serious challenge to chip thermal management with the power density increased exponentially. Interlayer microchannel liquid cooling is thought as a promising and scalable solution for cooling high heat flux 3D-IC. In this paper, firstly channel number, channel width and height parameters of rectangular channel are optimized by the method of multi-objective parameter optimization under given overall siz

Abstract:
A multimode waveguide that branches into several single-mode guides, all of different propagation constants, can route each mode into a different output channel. Such branching waveguides are important in splitting and recombining optical signals in guided-wave optoelectronic devices. A branching waveguide is fabricated as a sequence of waveguide sections, joined end to end. The distance between the parallel guiding channels is stepped discontinuously at the junctions between sections. Preserving this feature of the fabrication in our model, we first determine the local guided modes (supermode

Abstract:
The newly developed micro-photoluminescence measurement at low temperature has revealed one-dimensional diffusion of excitons in GaAs quantum wires with the lateral width of 7 - 30 nm fabricated by the selective growth technique using metal-organic chemical vapor deposition. The observed diffusion length increased with decreasing the wire width from 30 to 15 nm, and decreased from 15 to 7 nm, where the maximum diffusion length was about 4 μm for the 15-nm quantum wire. The change of the diffusion length vs. the wire width is expected to be due to the competition between the one-dimensional cha

Abstract:
The St. Francis River is a complex system that lies in the historic floodplain of the Mississippi and Ohio Rivers. The basin has undergone extensive anthropogenic modifications, including reservoir construction, large-scale channelization, and construction of leveed floodways. Several analyses of available gage data, lidar data, and historical research have provided a picture of geomorphic trends and an overall understanding of the river’s stability. The types of analysis used to determine trends included yearly low stage plots, stage-duration curves, specific gage analysis, water surface slop

Abstract:
Field and laboratory studies of insulating properties of mulches show that the changes they produce on the heat balance and the evaporation depend not only on the intrinsic characteristics of the material but also on the structure of air flow in boundary layer. Field measurements of the radiation balance of corn residue showed a decrease of reflectivity from 0.2 to 0.17 from fall to spring. The aerodynamic properties of the atmospheric surface layer were turbulent, with typical roughness length of 12 to 24 mm. Evaporation from corn residue covered soils in climate chambers simulating the diurn
