Let G = (V; E) be an undirected graph with a capacity function u : E!< + and let S 1 ; S 2 ; : : : ; S k be k commodities, where each S i consists of a pair of nodes. A set X of nodes is called feasible if it contains no S i , and a cut (X; X) is called feasible if X is feasible. Several optimization problems on feasible cuts are shown to be NP-hard. A 2-approximation algorithm for the minimum-...

the main aim in this research has been to determining the growth regime in iran based on an open economy concerning the bhaduri and marglin(1990) model.  this model which has been widely used in post keynesian economics is a kaleckian-post keynesian macroeconomic model which is based on effective demand. bhaduri and marglin(1990) concerning wage as a cost item as well as a component of aggregat...

Universities planning the provision of space for their teaching requirements, need to do so in a fashion that reduces capital and maintenance costs whilst still providing a high quality level of service. Space plans should aim to provide sufficient capacity without incurring excessive costs due to over-capacity. A simple measure used to estimate over-provision is utilisation. Essentially, the u...

We study connections among the ADM mass, positive harmonic functions tending to zero at infinity, and capacity of boundary asymptotically flat $3$-manifolds with nonnegative scalar curvature. First we give new formulae that detect mass via functions. Then derive a family monotone quantities geometric inequalities if underlying manifold has simple topology. As an immediate application, observe s...

Analytical modeling is a capacity planning function often used to accurately project future computing resource requirements. However, many capacity planners ignore activity "outside of the box" network changes, human behavior, and changing requirements which can introduce latent demand to an upgraded system and adversely affect the results of their best planning efforts. What is latent demand? ...

The combination of uncertain demand and lead times for installing capacity creates the risk of shortage during the lead time, which may have serious consequences for a service provider with dependent customers. This paper analyzes a model of capacity expansion with autocorrelated random demand and a fixed lead time for adding capacity. To provide a specified level of service, a discrete time ex...

Digital medical powerful tools for diagnosis, treatment and surgery and plays a vital role in modern healthcare delivery. Large storage capacity is needed for storing these images and for transmitting them. This leads to the strong demand for digital medical image compression and reliable transmission. In this study, we have applied three compression methods to medical images. In all the method...
