Influence of Thermocouple Thermal Inertia in Impingement Heat Transfer Experiments Using Transient Techniques

Peter Ott, Alexandros Terzis, Bernhard Weigand, Guillaume Wagner

A typical transient heat transfer experiment for an impingement cooling configuration requires usually a temperature step in the flow. A moving isotherm of the liquid crystal surface coating is then monitored using a video camera. However, for small imping ...

A novel low-profile shape memory alloy torsional actuator

Jamie Paik

This paper presents low-profile torsional actuators applicable for mesoscale and microscale robots. The primary actuator material is thermally activated Ni-Ti shape memory alloy (SMA), which exhibits remarkably high torque density. Despite the advantages o ...

Micromachined Dielectric Elastomer Actuators with Ion Implanted Electrodes

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We summarize recent results on micromachined dielectric elastomer actuators (DEA), or artificial muscles, whose compliant electrodes are made by low energy ion-implantation into an elastomer. Out-of-plane displacements in buckling mode of over 25% of the d ...

A spatial queuing model for the emergency vehicle districting and location problem

Nikolaos Geroliminis

Emergency response systems in urban areas should be located to ensure adequate coverage and rapid response time. We develop a model for locating emergency vehicles on urban networks considering both spatial and temporal demand characteristics such as the p ...
