Rate dependent aberrancy.
Forty patients with "rate dependent aberrancy" (RDA) were studied. This large group of patients permitted a clear definition of the syndromne and recognition of a number of features not previously described. These proved to have a significant bearing on the recognition and differential diagnosis of RDA and non-rate dependent aberrancy. It was found that a small change in cycle length, perhaps t...

متن کاملAn optimal policy for deteriorating items with time-proportional deterioration rate and constant and time-dependent linear demand rate
In this paper, an economic order quantity (EOQ) inventory model for a deteriorating item is developed with the following characteristics: (i) The demand rate is deterministic and two-staged, i.e., it is constant in first part of the cycle and linear function of time in the second part. (ii) Deterioration rate is time-proportional. (iii) Shortages are not allowed to occur. The o...
متن کاملCoupling Rate-Independent and Rate-Dependent Processes: Existence Results
We address the analysis of an abstract system coupling a rate-independent process with a second order (in time) nonlinear evolution equation. We propose suitable weak solution concepts and obtain existence results by passing to the limit in carefully devised time-discretization schemes. Our arguments combine techniques from the theory of gradient systems with the toolbox for rate-independent ev...
متن کاملAn inventory model with both stock-dependent demand rate and stock-dependent holding cost rate
In this paper, we develop an inventory model under a stock-dependent demand rate and stockdependent holding cost rate with relaxed terminal conditions. Shortages are allowed and partially backlogged in the model. The purpose of this study is to determine the optimal order quantity and the ending inventory level such that the total profit per unit time is maximized for the retailer. We first est...
