An Analytical Approximation for the Excess Noise Factor of Avalanche Photodiodes with Dead Space

Approximate analytical expressions are derived for the mean gain and the excess noise factor of avalanche photodiodes including the effect of dead space. The analysis is based on undertaking a characteristic-equation approach to obtain an approximate analytical solution to the existing system of recurrence equations which characterize the statistics of the random multiplication gain. The analytical expressions for the excess noise factor and the mean gain are shown to be in good agreement with the exact results obtained from numerical solutions of the recurrence equations for values of the dead space reaching up to 20% of the width of the multiplication region

Locating target at high speed using image decimation decomposition processing

We develop a decimation-decomposition processing technique that consists of judiciously selecting certain decimation-decomposed components of an image and then performing inter-component processing. For a (kx,ky)-decimation decomposition, there may be up to kxky decimation-decomposed components. The minimal surviving and maximal non-surviving lengths associated with inter-component processing algorithm allows for clutter suppression. By removing detection redundancies, one can locate the target at high speed. A “where-then-what” model is proposed for target tracking and recognition. It locates the target by-image decimation-decomposition processing first and then recognizes the target in question using a suitable image recognition technique

Effect of Convolution between Two Complex Waves having the Same Angular Frequencies with Amplitude Spectrum Analysis in Frequency Domain

Abstract: As digital signal processing continues to emerge as a major discipline in the field of electrical engineering, an even greater demand has evolved to understand the basic theoretical concepts involved in the development of varied and diverse signal processing systems. The most fundamental concepts employed are the sampling theorem, Fourier transforms, convolution, covariance, etc. The intent of this paper will be to address the concept of convolution and to present Convolved signal between Two Complex Waves having the same angular frequencies with Amplitude Spectrum Analysis in Frequency Domain The Fourier series gives us a very important and useful way of representing an image while it is a very powerful representation for many reasons, we will mainly introduce it as a way of understanding the effect of Convolution between two complex waves, how the losing local information of the spectrum

Effect of stage of maturity and frying time on the quality of Banana springs

Banana springs are a new snack food similar to banana chips. This study focuses on the quality improvement of banana springs. The effects of stage of maturity and time of frying on the quality of banana springs prepared from two varieties namely, Musa acuminata Colla cv. Berangan and Musa paradisiaca L. cv. Nangka, were evaluated. Five stages of maturity, i.e., i) mature, ii) early ripening, iii) intermediate ripening, iv) ripe, and v) overripe, were used in the trial. The total soluble solid (TSS) of two varieties at different maturity stages was measured. Banana springs were made by using spiral potato slicer. The slices of banana spring were 2±0.1 mm in thickness. The banana springs were deep fried in refined, bleached and deodorised (RBD) palm olein at a temperature of 170o C for 0, 3, 4, 5, and 6 minutes respectively. The fried banana springs were tested for their texture and crispiness. The samples were assessed for colour, flavour, texture, taste and overall acceptability by a 30-member taste panel. The TSS content of Nangka banana was greater than Berangan banana and the TSS content increased with maturity but it was a bit different between two varieties. Banana springs of Nangka variety had a higher value for texture (hardiness), especially at the early maturing stages in comparison to Berangan banana. Frying of banana springs for five and six minutes produced the same quality. An acceptable product with good taste, crispness, and the odour was obtained from both the varieties when fried at 170o C for 5 minutes. Nangka banana was better in respect of sweetness, odour, texture, and crispness vis-a-vis Berangan. Green matured banana (Maturity index I) of both the varieties was found suitable for the preparation of quality banana springs

General Closed Form Wave Solutions of Nonlinear Space-Time Fractional Differential Equation in Nonlinear Science

We have enucleated new and further exact general wave solutions, along with multiple exact traveling wave solutions of space-time nonlinear fractional Chan-Hillard equation, by applying a relatively renewed technique two variables -expansion method. Also, based on fractional complex transformation and the properties of the modified Riemann-Liouville fractional order operator, the fractional partial differential equations are transforming into the form of ordinary differential equation. This method can be rumination of as the commutation of well-appointed -expansion method introduced by M. Wang et al.. In this paper, it is mentioned that the two variables - expansion method is more legitimate, modest, sturdy and effective in the sense of theoretical and pragmatical point of view. Lastly, by treating computer symbolic program Mathematica, the uniqueness of our attained wave solutions are represented graphically and reveal a comparison in a submissive manner
