Abstract The influence of the fragment velocity gradient on hit density under dynamic missile-target meeting condition is discussed using theoretical analysis, and analytical relationship obtained. results show that static explosion conditions, independent group. Under distribution bandwidth fragments target becomes wider with increase group, decreases density.

as wireless networks with high data rate get widely deployed, improving the performance of tcp over these networks plays vital role. wireless link losses have dramatic adverse impact on tcp performance due to the difficulty in distinguishing the congestion losses from wireless link losses. we first, studied the various existing bandwidth estimation algorithms over the wireless networks. in this...

In this paper, we propose a multistage transimpedance amplifier (TIA) based on the local negative feedback technique. Compared with conventional global-feedback technique, proposed TIA has advantages of wider bandwidth, and lower power dissipation. The schematic characteristics circuit are described. Moreover, employs inductive peaking to increase bandwidth. is implemented using 65 nm complemen...

the aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. for this purpose, first, an exact mathematical model of phase locked loop (pll) based frequency synthesizer is described and analyzed. then, an exact closed-form formula in terms of synthesizer bandwidth and total output phase noise is extracted. based on this formula, the phase ...

This paper assesses the performance of dual header pulse interval modulation (DH-PIM) over indoor optical wireless systems. DH-PIM being anisochronous scheme offers a built-in symbol synchronization capability. Theoretical and simulation results demonstrate that DH-PIM offers shorter symbol length, improved transmission rate and bandwidth requirement and a comparable power spectral density prof...

We investigate the impact of stimulated Raman scattering (SRS) in multi-band transmissions. first derive and test against numerical results an extended Christodoulides-Zirngibl (ECZ) SRS model based on a triangular approximation gain. Then, we exploit ECZ context Gaussian noise (GN) model. generalize some known closed-form expressions self- cross-phase modulation variances, as well amplified sp...

Upscaling based on the bandwidth of the kernel function is a flexible approach to upscale the data because the cells will be coarse-based on variability. The intensity of the coarsening of cells in this method can be controlled with bandwidth. In a smooth variability region, a large number of cells will be merged, and vice versa, they will remain fine with severe variability. Bandwidth variatio...
