Local in vivo optical measurements of neurometabolic and neurovascular coupling mechanisms in the rodent cortex

This thesis introduces a novel approach for in vivo separation and quantification of spatio-temporal dynamics of optical coefficients (absorption, scattering), oxygen saturation (SO2) and haemoglobin concentrations within rat brain somatosensory cortex und ...

PyroMEMS: Improved Fabrication Methods and Ignition Reliability

David de Koninck

Generating large force/displacement actuators at the millimeter and sub-millimeter scales remains an important challenge for microsystems engineers. One promising solution is to integrate high-energy density solid propellant fuels in microsystems (pyroMEMS ...

Total Synthesis of (+/-)-Cylindricine C

Philippe Renaud, Kurt Schenk

A concise synthesis of (+/-)-cylindricine C and its C(13)-epimer is described. Starting from 1-octyne, cylindricine C and 13-epi-cylindricine C were prepared in 11% and 15% yields, respectively. The synthesis involves the preparation of the central tricycl ...

A survey of techniques and challenges in underwater localization

Marc Waldmeyer

Underwater Wireless Sensor Networks (UWSNs) are expected to support a variety of civilian and military applications. Sensed data can only be interpreted meaningfully when referenced to the location of the sensor, making localization an important problem. W ...

Decision rules for information discovery in multi-stage stochastic programming

Daniel Kuhn

Stochastic programming and robust optimization are disciplines concerned with optimal decision-making under uncertainty over time. Traditional models and solution algorithms have been tailored to problems where the order in which the uncertainties unfold i ...

Aperiodicity in the near field of full-scale rotor blade tip vortices

Karen Ann J Mulleners, Kolja Kindler

Blade tip vortices are the dominant vortical structures of the helicopter flow field. The inherent complexity of the vortex dynamics has led to an increasing interest in full-scale in situ experiments, where the near field, closely behind the blade, is of ...

People-Centric Mobile Sensing with a Pragmatic Twist: from Behavioral Data Points to Active User Involvement

Daniel Gatica-Perez

Mobile phones have recently been used to collect large-scale continuous data about human behavior. This people centric sensing paradigm is useful not only from a scientific point of view: Contextual user data has pragmatic value, too. Individuals whose dat ...

Multistage hydraulic gas compression/expansion systems and methods

Alfred Rufer

Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...

X chromosomal variation is associated with slow progression to AIDS in HIV-1-infected women

Jacques Fellay

AIDS has changed from a mostly male-specific health problem to one that predominantly affects females. Although sex differences in HIV-1 susceptibility are beyond doubt, the extent to which sex affects the onset and progression of AIDS has remained elusive ...

Structured random codes and sensor network coding theorems

Michael Christoph Gastpar

In the Shannon-theoretic analysis of joint source-channel coding problems, achievability is usually established via a two-stage approach: The sources are compressed into bits, and these bits are reliably communicated across the noisy channels. Random codin ...
