Ebook "Partitions, hypergeometric systems, and dirichlet processes in statistics" focuses on statistical inferences related to various combinatorial stochastic processes. Specifically, it discusses the intersection of three subjects that are generally studied independently of each other: partitions, hypergeometric systems, and Dirichlet processes. The Gibbs partition is a family of measures on integer partition, and several prior processes, such as the Dirichlet process, naturally appear in connection with infinite exchangeable Gibbs partitions.

The purpose of this paper "Linear topological invariants of spaces of holomorphic functions in infinite dimension" is to investigate the existence of generalized solutions for strongly parabolic systems in a cylindrical domain. The decay of the solution at infinity, depending on the right-hand of the equation, is also studied in this article.

The location of interface plays a pivotal role in studying on wetting phase transition of Bose-Einstein condensates (BECs) mixture. Beside parameters of system, the position of the interface depends on the applied boundary condition. Using double-parabola approximation (DPA), we consider the dependence of position of interface on parameters in semi-infinite space under Neumann boundary condition.

In this paper, we consider the second initial boundary value problem for strongly general Schr¨odinger systems in both the finite and the infinite cylinders QT , 0 < T ≤ +∞, with non-smooth base Ω. Some results on the existence, uniqueness and smoothness with respect to time variable of generalized solution of this problem are given.

One of effective approaches to the study of long - time behavior of infinite dimensional dynamical systems is based on the concept of inertial manifolds which was introduced by C. Foias, G. Sell and R. Temam (see [4] and the references therein). These inertial manifolds are finite dimensional Lipschitz ones, attract trajectories at exponential rate. This enables us to reduce the study of infinite dimensional systems to a class of induced finite dimensional ordinary differential equations.

This paper studies the active damping of the oscillations of lightly damped linear systems whose parameters are indeterminate or may change through time. Systems with an arbitrary number of vibration modes are considered. Systems described by partial differential equations, that yield an infinite number of vibration modes, can also be included. In the case of collocated feedback, i.e. the sensor is placed at the same location of the actuator, a simple fractional order differentiation or integration of the measured signal is proposed that provides an effective control.

Groundwater is an important source for irrigation in large tracks of India. This source has been considered as infinite and used indiscriminately without any disregard to recharge prospects. Reducing the over exploitation of ground water and its optimal utilization for irrigation is the need of the hour especially in low rainfall areas.

The infinite system of differential equations for the nonequilibrium Green functions of electrons in a single-level quantum dot connected with two conducting leads is truncated by applying the mean-field approximation to the mean values of the products of four operators. As the result the system of Dyson equations for the two-point real-time nonequilibrium Green functions in the Keldysh formalism as well as that of the two-point imaginary-time Green functions are derived.

Creation of optimal tax and budget systems is one of the Difficult problems of economic science. One of the most important areas of tax reform is to develop a tax code in the aspect of optimal tax gravity. The new tax code - a step to improvement, since a number of reduced taxes and simplified tax system at the same time. In order to once and for all ended the confrontation between the Government of the Infinite and Taxpayer, resolved the problem of budget revenues, was a powerful national economy, it is necessary to develop a tax code so that its weight was exactly 38.

Vibro-acoustic analysis of a finite orthotropic laminated double-composite plate with enclosed air cavity on an infinite acoustic rigid baffle is investigated analytically. Using the acoustic velocity potential to describe the acoustic vibration performance of a simple supported structure, the sound transmission loss (STL) is calculated from the ratio of incident to transmitted acoustic powers.

Although Egypt has already reached the water poverty limit, it possesses a high potential of brackish groundwater available from different aquifers. All Arab countries lie in the best sun-belt region in the world and Egypt has the highest number of sun hours all year round. Solar energy for groundwater desalination is an independent infinite energy resource; it has low running costs and reduces the contribution of greenhouse gases (GHG) to global warming.

With the development of power system interconnection, the low-frequency oscillation is becoming more and more prominent which may cause system separation and loss of energy to consumers. This paper presents an innovative robust control for power systems in which the operating conditions are changing continuously due to load changes. However, practical implementation of robust control can be fragile due to controller inaccuracies (tolerance of resistors used with operational amplifiers).
