This paper proposes an adaptive pricing system with scheduling to balance the demand for contents and to realize an effective use of resources in contents delivery networks. In the proposed adaptive pricing system, the table of the service levels and prices (tariff) is shown to each user at the start of service and each user chooses one of the service classes. These prices are decided adaptivel...

In this paper, the problem of lot sizing, scheduling and delivery of several items in a two-stage supply chain over a finite planning horizon is studied. Single supplier via a flexible flow line production system (FFL), produces several items and delivers them directly to an assembly facility. Based on basic period (BP) strategy, a new mixed zero-one nonlinear programming model has been develop...

We solve the problem of uplink video streaming in CDMA cellular networks by jointly design the rate control and scheduling algorithms. In the pricing-based distributed rate control algorithm, the base station announces a price for the per unit average rate it can support, and the mobile devices choose their desired average transmission rates by balancing their video quality and cost of transmis...

This study investigates how acoustic and lexical properties of spontaneous speech in dialogs affect perceived social attractiveness in terms of speaker likeability, friendliness, competence, and self-confidence. We analyze a database of longer spontaneous dialogs between German female speakers and the mutual ratings that dialog partners assigned to one another after every conversation. Thus the...
