Benefits of Continuous Descent Operations in High-Density Terminal Airspace Considering Scheduling Constraints

Maryam Kamgarpour

This study estimates the potential benefits of continuous descents for more than 480,000 flights to 25 major airports in the National Airspace System. While reduced fuel consumption and greenhouse gas emissions are expected for these procedures, the benefi ...

Realization of a solid-propellant based microthruster using low temperature co-fired ceramics

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Jaya Thakur

The introduction of micro-spacecrafts in the space industry has led to the development of various micro-propulsion techniques. Microthrusters are micropropulsion devices used in a microspacecraft for precise station keeping, orbit adjustment, attitude cont ...

Wave induced velocities inside a model seagrass bed

Laboratory measurements reveal the flow structure within and above a model seagrass meadow (dynamically similar to Zostera marina) forced by progressive waves. Despite being driven by purely oscillatory flow, a mean current in the direction of wave propaga ...

A Modular Approach towards Wearable Computing

Xavier Righetti

Thanks to recent improvements in electronics, conductive materials and energy storage capabilities, we are now able to embed small circuits but also ultra-mobile PCs (UMPC) into clothes. These devices are able to sense, process and communicate information ...

Modelling Complex Fenestration Systems

Jean-Louis Scartezzini, Anothai Thanachareonkit

Complex Fenestration Systems (CFS) are widely studied to help redirecting daylight into a room in order to optimise its luminous properties. Daylighting designers and researchers usually employ physical and virtual models to assess their daylighting perfor ...

Analysis of gait and coordination for arthroplasty outcome evaluation using body-fixed sensors

Hooman Dejnabadi

The importance of evaluation of an orthopedic operation such as hip or knee arthroplasty has long been recognized. Many definitions of outcome and scoring questionnaires have been used in the past to assess the outcome of joint replacement. However, these ...
