Large commercial latency-sensitive services, such as web search, run on dedicated clusters provisioned for peak load to ensure responsiveness and tolerate data center outages. As a result, the average load is far lower than the peak load used for provision ...
The construction industry contributes to more than a third of the global energy demand and consumes almost half of all mined material resources. It is thus important to include energy and material efficiency criteria for the design of civil structures. Ada ...
We present variable stiffness dielectric elastomer actuators (DEAs), combining a single DEA actuator with embedded shape memory polymer (SMP) fibers, which can be electrically addressed to locally reduce the stiffness by a factor of 100. The device accommo ...

This paper provides a general sensorless method to control the position of a linear actuator. After a review of the solutions used so far, this new method is applied to identify keys passing through a linear actuator used in an industrial textile machine. ...
Adaptive joints are structural joints made of materials with enhanced transduction properties that can vary their stiffness via solid-state actuation (e.g. thermal, mechanical). In this work, stiffness tuning is used to switch the joint between a ‘locked’ ...
This paper discusses about a low-cost wearable assistive device designed for people carrying back loads in mountainous regions of Uttarakhand, a northern state of India. People usually carry commodities like stationeries, gas cylinders, cow feeds and other ...
We present a simple open-loop method to increase the response speed and suppress the viscoelastic creep of dielectric elastomer actuators. The parameters of the model can be extracted from two simple measurements: a strain vs. voltage ramp, and the strain ...
The report focuses on the development of a practical and scalable methodology for the planning and operation of Active Distribution Networks (ADNs) with particular reference to the integration of Energy Storage Systems (ESSs) owned, and directly controlled ...
The testing of mode III and mixed mode failure is every so often encountered in the dedicated literature of mechanical characterization of brittle and quasi-brittle materials. In this work, the application of the mixed strain displacementfinite element for ...
