Design methodology and numerical optimization of ultrasonic transducers for spinal surgery

Daniel Porto

Nowadays, the general trend towards to minimally invasive interventions is present in all the medical domains. For the surgical intervertebral spinal disc cutting or removal domain, it is particularly a necessity because the manual methods currently employ ...

Uncertainty Feature Optimization for the Airline Scheduling Problem

Matteo Salani, Niklaus Eggenberg

Uncertainty Feature Optimization is a framework to cope with optimization problems due to noisy data, using an implicit characterazation of the noise. The Aircraft Scheduling Problem (ASP) is a particular case of such problems, where disruptions randomly p ...

Optimization of cascade stilling basins using GA and PSO approaches

David Andrew Barry, Roham Bakhtyar

In high head dams, the kinetic energy at the spillway toe is very high and the tail-water depth available for energy dissipation is relatively small. Cascade stilling basins are energy dissipation systems for high head dams, the design of which is based on ...

Source-to-source architecture transformation for performance optimization in BIP

Joseph Sifakis

BIP (Behavior, Interaction, Priorities) is a component framework for constructing systems from a set of atomic components by using two kinds of composition operators: interactions and priorities.In this paper we present a method that transforms the interac ...

How Live Can a Transactional Memory Be?

Rachid Guerraoui, Michal Kapalka

This paper asks how much liveness a transactional memory (TM) implementation can guarantee. We first devise a formal framework for reasoning about liveness properties of TMs. Then, we prove that the strongest liveness property that a TM can ensure in an as ...

On Obstruction-Free Transactions

Rachid Guerraoui, Michal Kapalka

This paper studies obstruction-free software transactional memory systems (OFTMs). These systems are appealing, for they combine the atomicity property of transactions with a liveness property that ensures the commitment of every transaction that eventuall ...

Analytical design and optimization of ultrasonic vibrational transducers for spinal surgery

John Murphy

Just about every other technical publication you pick up these days makes sweeping statements concerning the pressures on scientists, engineers, and industries as a whole to get to market in less time, with an improved, less expensive product. I am reminde ...

Optimization of a Single Phase Ultrasonic Linear Motor

Yves Perriard, José Fernandez Lopez, Markus Flückiger

Piezoelectric ultrasonic motors are superior to electromagnetic micromotors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimization potenti ...
