In order to support emerging network businesses, such as Voice-over-IP (VoIP), virtual learning, video conferencing, and telemedicine, the Internet has to provide classes of service that are better than traditional ‘best-effort’ service. In computer networks, Quality of Service (QoS) is defined as the mechanisms that allow differentiation of network services based on their unique service requir...

By employing dynamic pricing, the act of changing prices over time within a marketplace, sellers have the potential to increase their revenue by selling goods to buyers “at the right time, at the right price.” As dynamic pricing systems become necessary as a competitive maneuver and as market mechanisms become more complex, there is a greater need for pricing agents to be used, and also a great...

This paper proposes the dynamic window approach to reactive collision avoidance for mobile robots equipped with synchro-drives. The approach is derived directly from the motion dynamics of the robot and is therefore particularly well-suited for robots operating at high speed. It di ers from previous approaches in that the search for commands controlling the translational and rotational velocity...

Dynamic Spectrum Allocation (DSA) has been viewed as a promising approach to improving spectrum efficiency. With DSA, Wireless Service Providers (WSPs) that operate in fixed spectrum bands allocated through static allocation can solve their short-term spectrum shortage problems resulting from the bursty nature of wireless traffic. Such DSA mechanisms should be coupled with dynamic pricing schem...

The dynamic pricing problem concerns the determination of selling prices over time for a product whose demand is random and whose supply is fixed. We approach this problem in a novel way by formulating a dynamic optimization model in which the demand function is iso-elastic but the random demand process is quite general. Ultimately, what we find is a strong parallel between the dynamic pricing ...

For improving the current pricing mode of medical services, the present study seeks to explore the pricing elements and processes, and establish the dynamic pricing model of involving both the government and hospitals. The pricing process and mathematical model show the logical relationships between medical prices and pricing elements. The causal relationship model reveals how to accomplish dyn...

We empirically investigate predictions from alternative intermediary asset pricing theories. The theories distinguish themselves in their use of intermediary equity or leverage as pricing factors or forecasting variables. We find strong support for a parsimonious dynamic pricing model based on broker-dealer leverage as the return forecasting variable and shocks to broker-dealer leverage as a cr...

In this paper we present an analysis of investment incentives for network infrastructure owners under two different pricing strategies: congestion based negative externality pricing and the prevalent flat rate pricing. The challenge in a networked environment is to increase capacity of the different components of the network appropriately based on demand for these different components. We devel...

Cruising-for-parking constraints mobility in urban networks. Car-users may have to cruise for on-street parking before reaching their destinations. The accessibility and the cost of parking significantly influence people’s travel behavior (such as mode choice, or parking facility choice between on-street and garage). The cruising flow causes delays eventually to everyone, even users with destin...
