A model of viscoelasticity with time-dependent memory kernels

A New Continuous Multi-State Reliability Model with Time Dependent Component Performance Rate

A CSS1†is a system with the continues-state components. When a component has the ability to obtain all the situations from completely working to completely failed, it named continues-state component. In the real world, performance rate of elements are continuous and decrease by time. Continuity of components causes infinite working states and grows up the system states. In this paper we propose...

Mechanics of Time Dependent Materials Based on Linear Viscoelasticity

A New Inventory Model for Deteriorating Items with Price-dependent Demand, Time-value of money, and Shortages

This paper presents a discounted cash-flow approach to an inventory model for deteriorating items with the two-parameter Weibull distribution. According to our proposed model, two shortages are considered: back-orders and lost-sales, in which the back-order rate is a varying function of the time when the shortage happens. In general, the demand rate is a linear function of the selling price...

A New Inventory Model for Deteriorating Items with Price-dependent Demand, Time-value of money, and Shortages

This paper presents a discounted cash-flow approach to an inventory model for deteriorating items with the &#10two-parameter Weibull distribution. According to our proposed model, two shortages are considered: back-orders and lost-sales, &#10in which the back-order rate is a varying function of the time when the shortage happens. In general, the demand rate is a linear function of the selling p...

Data dependent kernels in nearly-linear time

We propose a method to efficiently construct data-dependent kernels which can make use of large quantities of (unlabeled) data. Our construction makes an approximation in the standard construction of semi-supervised kernels in Sindhwani et al. (2005). In typical cases these kernels can be computed in nearly-linear time (in the amount of data), improving on the cubic time of the standard constru...
