Mark Balenzuela: Accurate Gaussian Mixture Model Smoothing using a Two-Filter Approach

Date & Venue
Tuesday, 04 December 2018, 11:00am
EF122

Abstract
Gaussian Mixtures (GMs) can be used as a universal density approximator. As such, they can capture multimodal, skewed, and heavy-tailed characteristics of densities describing dynamic behaviour, which appear throughout finance, robotics, and fault detection. In this seminar, we consider smoothing for a class of state-space models where linear […]

Jarrad Courts – Larger Scale Nonlinear State space System Identification

Date & Venue
Thursday, 01 November 2018, 02:00PM
EF122

Abstract
System identification for large scale continuous time nonlinear state space models, as common in mechatronics applications, remains a challenging task. Existing system identification methods can be deficient for complex nonlinear problems and computationally do not scale well on large problems, the focus of this work is to alleviate […]

David Harcombe – Nanoscale Demodulation and Sensing

Date & Venue
Wednesday, 17 October 2018, 02:00PM
EF122

Abstract
Conventional high-speed amplitude demodulation techniques are compared and shown to be incompatible with multifrequency atomic force microscopy (MF-AFM), due to a lack of sensitivity to multiple frequency components. Novel model-based methods including a Kalman and Lyapunov filter are proposed, which alleviate this issue while maintaining very high bandwidths. Additionally, mass-sensing through microcantilever resonance […]

Nathan Bartlett – Multi-Extended Target Tracking

Date & Venue
Thursday, 04 October 2018, 02:00PM
EF122

Abstract
Extended targets are targets which potentially generate more than one measurement per time step. They are encountered in numerous applications, spanning from vehicle tracking with automotive radar, pedestrian tracking using laser range sensors, and surface vessel tracking with marine X-band radar. The generation of multiple measurements per time […]

Omid Tayefeh – Exposure Planning for Scanning Laser Lithography

Date & Venue
Friday, 31 August 2018, 10:30AM
EF122

Abstract
Lithography is the process of selectively exposing optically sensitive materials during semiconductor fabrication. One issue with standard projection lithography is the high cost of infrastructure and mask sets. These costs may be prohibitively expensive for prototyping and low-volume production. Scanning-beam lithography methods are attractive alternatives to projection lithography […]

Abstract
Machine learning is currently a hot research area which also is getting a lot of attention in the media. Many are talking about artificial intelligence and how automation will change the world and put people out of work. As a community, machine learning is built around open-software and […]

Hamed Sadeghian – Nano-Mechatronics Instrumentations to Probe Interactions at the Nano-scale

Date & Venue
Tuesday, 17 July 2018, 02:00PM
EF122

Abstract
Understanding the interactions of matter at nano-scale has become the key for the success of several applications. In nanoelectronics or semiconductor industry, it helps for better manufacturing (higher resolution towards sub-10 nm structures, more complex structures) and reliable nanometrology and nano-inspection (for improving the yield of process). One […]

Meysam Omidbeike – Independent Estimation of Temperature and Strain in Tee-Rosette Piezoresistive Strain Sensors

Date & Venue
Friday, 06 July 2018, 01:00PM
EF122

Abstract
This article proposes a novel technique for independent measurement of strain and temperature in piezoresistive strain sensors congured in a tee-rosette. The most notable property of piezoresistive sensors is their easy integration into MEMS fabrication processes and nanopositioning systems, which makes them highly advantageous for both size and […]

Michael Ruppert – Design of Hybrid Piezoelectric/Piezoresistive Cantilevers for Dynamic-mode Atomic Force Microscopy

Date & Venue
Tuesday, 03 July 2018, 02:00PM
EF122

Abstract
Atomic force microscope cantilevers with integrated actuation and sensing on the chip level provide several distinct advantages over conventional cantilever instrumentation. These include clean frequency responses, the possibility of down-scaling and parallelization to cantilever arrays as well as the absence of optical interferences. However, the two major difficulties […]
