nowadays accountancy of human resources has become one. of the most important issues in the field of maintaining human resources in the organizations. there ate different methods to use for controlling human resource that in this essay the major emphasis has been put on degree of replacement or rotation, absenteeism, and the relationship between employees. in accountancy of human resources the ...

Most models will attempt to extract losses (interception, surface storage, infiltration) from the input and build a runoff hydrograph using empirical curves or by routing the excess water. Even the simplest models generally involve many parameters to describe these processes. Some parameters are estimated from published values, and others are set based on past practice and calibration of the mo...

Extreme climate events are becoming more intense in Melbourne in recent years. This increasing intensity of excessive rainfall has an adverse effect on the sewer network by causing sewage overflow hazards. Extreme rainfall events increase flow into the sewer system, both directly (inflow) and through infiltration into sewer. As a result of this Rainfall Derived Infiltration and Inflow (RDII), S...

The seminal work by Edmonds [9] and Lovász [39] shows the strong connection between submodular functions and convex functions. Submodular functions have tight modular lower bounds, and a subdifferential structure [16] in a manner akin to convex functions. They also admit polynomial time algorithms for minimization and satisfy the Fenchel duality theorem [18] and the Discrete Seperation Theorem ...

Abstract This study presents the preliminary stage of development a conjunctive surface-subsurface model for simulating flow in swale. The surface is modelled by one-dimensional dynamic wave equation. To improve accuracy, third-order numerical scheme used to solve advection terms model. Meanwhile, subsurface as vertical through nondeformable porous media without air compression effect. At stage...
