An analytical relationship between the statistical significance of an observed signal and the signal width in case of a large background was obtained. It can help to explain why high-energy experiments may have different conclusions on the existence of new particles. We illustrate our approach using the experimental data on searches for the Θ(1530) pentaquark state. The obtained relationship is...

Hybrid image sensors combine advantages of the two leading imaging technologies (the fill factor of CCD, and the signal processing of CMOS) via vertical integration. This report derives a simple model for the photodetector of the hybrid image sensor, and the affiliated set of differential equations. This bounded-value problem is subsequently solved numerically in 1D, and a simple analytical mod...

In this paper Maximal Ratio Combining (MRC) technique over Rayleigh fading channel is described and some statistical characteristics of received signal envelope are analyzed. For analytical and numerical evaluation of system performance, the probability density functions (pdf) of received signal envelope after MRC are analyzed like particular solutions of corresponding differential equation, wh...

A narrowband multiuser receiver based on successive signal detection and subtraction, is proposed. The Bit Error Rate (BER) performance for M-PSK modulated signals is evaluated and analytical approximations for the BER of the individual signals are presented and compared to the actual BER. The effect of inaccurately estimated signal parameters due to noise is analyzed. BER results are presented...

Analytical compact form models for the signal transients and crosstalk noise of inductive-effectprominent multi-coupled RLC lines are developed. Capacitive and inductive coupling effects are investigated and formulated in terms of the equivalent transmission line model and transmission line parameters for fundamental modes. The signal transients and crosstalk noise expressions of two coupled li...

In this paper, analytical assessment of overlayinband device-to-device (D2D) communications is investigated, under cellular-network-assisted (coordinated) scheduling. To this end, a simple scheduling scheme is assumed that takes into account only local (per cell) topological information of the D2D links. Stochastic geometry tools are utilized in order to obtain analytical expressions for the in...

Power minimization is an important objective in present day VLSI design. Macromodels for power dissipation can be used to estimate power at a high-level of abstraction. High-level power estimation methods provide the designer with more exibility to explore design trade-o s early in the design cycle. In this paper, we present closed-form analytical expressions for power consumption of macro-bloc...

Delays that individual vehicles may experience at a signalized intersection are usually subject to large variation due to randomness of traffic arrivals and interruption caused by traffic signal control. While such variation may have important implications for the planning, design and analysis of signal controls, currently there is no analytical model available to quantify it. This paper descri...

The objective of this paper is to propose a novel tubular linear machine with hybrid permanent magnet arrays and multiple movers, which could be employed for either actuation or sensing technology. The hybrid magnet array produces flux distribution on both sides of windings, and thus helps to increase the signal strength in the windings. The multiple movers are important for airspace technology...

INTRODUCTION Most of the prior work in compressed sensing MRI has been based on pre-defined transformations to sparsify image representations, e.g. discrete cosine transforms (DCT), wavelets, and finite differences [1]. Even though an analytical transformation usually features a fast implementation, its performance as a sparsifying transform is limited by the underlying basis functions, which t...
