We introduce a specific transport and transmission scheme for video-on-demand (VoD) called constant-rate transmission and transport (CRTT). CRTT establishes a constant bit-rate (CBR) virtual channel between the video provider and the viewer’s set-top box (STB) and then transmits cells from the provider into this channel at a constant rate. Since we assume that the number of cells in a frame is ...

In this paper we analyze a stochastic dynamic advertising and pricing model with isoelastic demand. The state space is discrete, time is continuous and the planing horizon is allowed to be finite or infinite. A dynamic version of the Dorfman–Steiner identity will be derived. Explicit expressions of the optimal advertising and pricing policies, of the value function and of the optimal advertisin...

Large number of researcher papers has been published for inventory lotsize models under trade credit financing by assuming that demand rate is constant. But demand rate is often not constant. During the growth stage of the product life cycle, the demand function increases with time. In this paper we extend the constant demand to timedependent demand. This paper derives the problem of determinin...

the main logic behind the demand for life insurance is to hedge against the labor income uncertainty due to premature death of a wage earner. in other words, life insurance is the device by which this labor income uncertainty is handled. for insurers, the uncertainty arises from the lack of knowledge about the age of death of the wage earner. this paper attempts to derive life insurance demand ...

In smart grids paradigm, versatile demand response programs have been devised to accommodate the load flexibilities in optimal scheduling of distribution networks and increasing the techno-economic efficiency of electrification process. The initial models for prioritizing the demand response programs are mainly valid for the case of constant and deterministic load profiles. These models are tac...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...
