This paper presents a new ultra-wideband (UWB) bandpass filter (BPF) with sharp roll-off and dual-notched bands. The filter consists of a triangle ring multi-mode resonator (MMR) with the stub-loaded resonator (SLR) for controlling the two transmission zeros at 2.8 / 11 GHz, the embedded open-circuited stub and the asymmetric tight coupled input/output (I/O) lines for introducing the dual notch...

The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The Euler-Bernoulli beam theory ba...

Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...

In this paper the cellular aspects of a concept will be investigated that introduces a new element called forwarding mobile terminal (FMT) to the HiperLAN/2 (H/2) world. The FMT is designed to extend the area of an H/2 access point and provide users in uncovered areas with access to the fixed Internet by providing an intermediate hop. The FMT is a modified H/2 mobile terminal which only needs d...

Subthreshold filters offer the low power and wide tunable range required for use in fully implantable bionic ears. The major design challenge that must be met is increasing the linear range. A capacitive-attenuation technique is presented and refined to allow the construction of wide-linear-range bandpass filters with greater than 1 pp swings. For a 100–200 Hz fully differential filter with sec...

Laser and radar technology is an area of interest in the field of military research. Currently military services face many challenges in maintaining financial stability and sustainability in training phases. Military trainings exercises focus mainly on strengthening the simulation culture rather than focusing on theoretical aspects. In the sphere of military radars, simulators play very importa...

In this paper, an acoustic echo canceller (AEC) based on an M-channel infinite-impulse response (IIR) cosine-modulated filter bank (CMFB) with near-perfect reconstruction (PR) property is proposed. The use of a 2-channel lossless lattice section with 1 st order allpass filter in the design of the prototype filter that is common to both the analysis and the synthesis filter banks permits the fil...

The subjective visual vertical (SVV) indicates perceived direction of gravity. Even in healthy human subjects, roll angle-dependent misestimations, roll overcompensation (A-effect, head-roll > 60° and <135°) and undercompensation (E-effect, head-roll < 60°), occur. Previously, we demonstrated that, after prolonged roll-tilt, SVV estimates when upright are biased toward the preceding roll positi...

733 Abstract— This paper has studied subthreshold characteristics for double gate(DG) MOSFET using Gaussian function in solving Poisson's equation. Typical two dimensional analytical transport models have been presented for symmetrical Double Gate MOSFETs (DGMOSFETs). Subthreshold swing and threshold voltage are very important factors for digital devices because of determination of ON and OFF. ...

We address the so-called “roll-off” phenomenon: Selective abstention in multiple elections. We present a discuss a novel model of decision making by voters that explains this as a result of differences in quality and quantity of information that the voters have about each election. In doing so we use a spatial model that differs from the Euclidean one, and is more naturally applied to modelling...
