Condensation-Driven Aggregation in One Dimension (2008)
We propose a model for aggregation where particles are continuously growing by heterogeneous condensation in one dimension and solve it exactly. We show that the particle size spectra exhibit...

This paper describes the first threats of H5N1 avian influenza outbreaks in Egypt recorded from February to December 2006 in commercial and domestic poultry from different species and summarizes the...

The effects of modified atmosphere packaging at low storage temperature on the quality of organic bananas (cv. Cavendish) were investigated. Polybags, with or without an ethylene scavenger,...
Scale Invariant Fractal and Slow Dynamics in Nucleation and Growth Processes (2004)
We propose a stochastic counterpart of the classical Kolmogorov-Johnson-Mehl-Avrami (KJMA) model to describe the nucleation-and-growth phenomena of a stable phase (S-phase). We report that for growth...
An analytic model for a cooperative ballistic deposition in one dimension (2002)
Hassan, M. K., Wessel, N., Kurths, J.
We formulate a model for a cooperative ballistic deposition (CBD) process whereby the incoming particles are correlated with the ones already adsorbed via attractive force. The strength of the...
Jamming and asymptotic behavior in competitive random parking of bidisperse cars (2002)
Hassan, M. K., Schmidt, J., Blasius, B., Kurths, J.
We propose a generalized car parking problem where either a car of size $\sigma$ or of size $m\sigma$ ($m>1$) is sequentially parked on a line with probability $q$ and $(1-q)$, respectively. The free...
Can randomness alone tune the fractal dimension? (2002)
We present a generalized stochastic Cantor set by means of a simple {\it cut and delete process} and discuss the self-similar properties of the arising geometric structure. To increase the...

A field experiment was conducted at the Regional Agricultural Research Station of Barisal, Bangladesh during the Kharif season of the year 2000 to find the optimum fertilizer rate for summer mungbean...
Jamming coverage in competitive random sequential adsorption of binary mixture (2001)
Hassan, M. K., Schmidt, J., Balsius, B., Kurths, J.
We propose a generalized car parking problem where cars of two different sizes are sequentially parked on a line with a given probability $q$. The free parameter $q$ interpolates between the...
Can Smoluchowski equation account for gelation transition? (2001)
We revisit the scaling theory of the Smoluchowski equation with special emphasis on the dimensional analysis to derive the scaling ansatz and to give an insightful foundation to it. It has long been...
Transition from random to ordered fractals in fragmentation of particles in an open system (2001)
We consider the fragmentation process with mass loss and discuss self-similar properties of the arising structure both in time and space, focusing on dimensional analysis. This exhibits a spectrum of...

We present a number models describing the sequential deposition of a mixture of particles whose size distribution is determined by the power-law $p(x) \sim \alpha x^{\alpha-1}$, $x\leq l$ . We...
Fractals, Multifractals and the Science of Complexity (1996)
We discuss the formation of stochastic fractals and multifractals using the kinetic equation of fragmentation approach. We also discuss the potential application of this sequential breaking and...
