Abstract: In the recent literature, attempts have been made to propose new statistical distributions for modeling real phenomena of nature by adding one or more additional shape parameter (s) to the distribution of baseline random variable. The major contribution of these distributions are to obtain monotonic and non-monotonic shaped failure rates. This short article, offers a clarification to the research articles proposed by Al-Kadim and Boshi [4], El-Bassiouny et al. [9] and El-Desouky et al. [10]. A brief discussion on the properties of this general class is given. A future research motivation on this subject is also provided.

Abstract: This paper presents the analytical solution to Richards’ equation of hydrology for unsaturated soils. In order to facilitate the design and analysis of a real-time automatic irrigation system, an accurate model must be developed for the system. Richard’s equation of water hydrology may be used to model part of the irrigation system. The major problem with the application of Richard’s equation is in the linearization of the non-linear partial differential equation (PDE). In this paper, an empirical relationship stated by Gardner [1] was used to linearize the nonlinear PDE. The solution for the PDE was obtained using separation of variables technique.

Abstract: For the last time have been saved up in the large volume of laboratory and experimental and actual data which, in the turn, confirm need of the accounting of nonlinear deformations of rocks at the solution of hydrogasdynamic problems of development of oil and gas pools. These deformations of rocks, generally have rheological character which can affect indicators of development of the deposits of oil and gas developed at various natural and technological modes noticeably. Considering this circumstance, article is devoted to the solution of a task the movement of the gas-cut oil to the well in oil layer which breeds are exposed to creeping deformation, on condition of the set well production. The numerical solution of a task has been received and on the basis of hypothetical model of layer the numerical experiment has been made. By results of numerical calculations character influence of creep of rocks on the defined indicators of development of the oil pool has been established.
