Increasing in energy consumption, particularly with the ever-increasing growth and development of urban systems, has become a major concern in most countries. In this paper, the authors propose a cost-effective ZigBee-based building energy monitoring and control system (ZBEMCS), which is composed of a gateway, a base station, and sensors. Specifically, a new hardware platform for power sensor n...

control freeway traffic in the United States, particularly in California. It is recognized that ramp metering can directly control the flow into the freeway (demand) and the average density immediately downstream, which indirectly affects the traffic upstream. After drivers enter the freeway, their collective behaviors are not controlled, which determines the traffic flow pattern. In addition, ...

The power grid is currently undergoing changes towards highly volatile and localized energy production and storage, supported by IT and communication components. Smart Metering is going to provide fine-grained measurement and automatic remote reading of consumption and production amounts. It enables flexible tariffing and dynamic load optimization, ultimately aiming at cost and consumption redu...

In this work, for the first time, we demonstrate nanoscale droplet generation from a continuous electrowetting microchannel using a simple and precise imagebased droplet volume metering technique. One of the most popular ways of droplet generation in electrowetting devices is to split a droplet from a preloaded volume as a fluid reservoir. This method is effective, but lowers volume consistency...

This paper describes the fundamental design and development of a new decision-support tool for time-based arrival metering, referred to as the En Route Descent Advisor (EDA). This automation is being developed at NASA Ames Research Center as a component of the Center-TRACON Automation System (CTAS). EDA computes advisories for the air-traffic controller to help deliver aircraft to an arrival-me...

When there are different routes from origin to destination in a network, the traffic divides itself over these routes. The resulting assignment is often determined by the travel times on the different routes. When control measures are implemented the travel times for some routes change, which can lead to a change in the assignment. This change in assignment can effect the performance of the who...

In the context of energy efficiency, smart metering solutions are receiving growing attention as they support the automatic collection of (fine-grained) consumption data of appliances. While the capability of a stakeholder (such as a consumer, an utility, or a third-party service) to access smart metering data can give rise to innovative services for users, it makes the control of data release ...

Continuous descent operations (CDO) with controlled times of arrival (CTA) at one or several metering fixes could enable environmentally friendly procedures at the same time that terminal airspace capacity is not compromised. This paper focuses on CTA updates once the descent has been already initiated, assessing the feasible CTA window (and associated fuel consumption) of CDO requiring neither...

Occupancy is the percent of time a traffic loop detector embedded in the road pavement is occupied by vehicles. This term is usually used as a substitution for the traffic density which is not feasible to obtain from detectors. One of the recent applications for the traffic occupancy is in calculating the timing for traffic signals on motorway entrances (Ramp Metering, RM). Most of the existing...
