Privacy is a major issue today as more and more users are connecting and participating in the Internet. This paper discusses privacy issues associated with web metering schemes and explores the dilemma of convincing interested parties of the merits of web metering results with sufficient detail, and still preserving users’ privacy. We analyse different categories of web metering schemes using a...

Net metering is a utility metering practice that encourages direct consumer investment in renewable energy technologies. Laws and regulations that establish net metering practices now exist in 22 states. Net metering enables electricity customers with small generators to receive a higher value for some or all of the electricity they generate. This is accomplished by allowing the electric meters...

Despite the continuous advances in the fields of control and computing, the design and deployment of an efficient Large-scale Nonlinear Traffic Control System (LNTCS) remains a significant objective. This is mainly due to the complexity and the strong nonlinearities involved in the modeling of traffic flow processes. Practical control design approaches are often based on simplified models about...

We use a mathematical model based on hybrid automata theory to describe air traffic flow in arrival mgions near airports. We show that the problem of scheduling the arrival flow subject to airspace and airport metering constraints may he formulated as a Mized Integer Linear Pmgmm (MILP). We demonstrate an implementation of this program, which accepts Air %fie Contml (ATC) data, performs the sch...

The Tools for Operations Planning (TOPL) employs the Link-Node Cell Transmission model for macroscopic freeway traffic simulations for specifying operational strategies like ramp metering, demand and incident management.Traffic flow and occupancy data from loop detectors is used for calibrating these models and specifying the inputs to the simulation. However, flow data from ramps are often to ...

The differentiated services (diffserv) architecture defines a new framework for the support of quality of service (QoS) in IP-based networks. In this paper, we focus on the mechanisms used to implement the Expedited Forwarding (EF) Per-Hop Behavior (PHB). We analyze these mechanisms with respect to two main QoS parameters: Delay and delay variation. Within a diffserv node we study the impact of...

Traffic simulation models have increasingly been used due to low cost, time saving and ability to examine possible solutions for traffic-related problems without interrupting the real life traffic conditions during testing alternative scenarios. Recently, visual angle car following model has been studied and examined by the author for use in developing a microsimulation car following model. The...

Cloud computing is a new computational and commercial model. It brings the illusion of a virtually infinite computing infrastructure/platform that provides advanced features. The increased number of VMs and applications in virtualized data centers triggers serious scalability concerns with regards to monitoring. Many features of Cloud need supports from underlying Cloud monitoring system. There...

In this paper a model-based traffic control is used to design variable speed limits and onramp metering rates in order to reduce road traffic generated area-wide emissions near freeways. First an area-wide emission model is proposed and next a nonlinear model predictive control (MPC) approach is applied. The objectives of the MPC controller considered are the emissions, dispersions of emissions...
