    Various standoff sensing techniques employing optical spectroscopy have been developed to address challenges in safely identifying trace amounts of explosives at a distance. A flexible anodic aluminum oxide (AAO) microcantilever ...
  • New Confocal Hyperbola-based Ellipse Fitting with Applications to Estimating Parameters of Mechanical Pipes from Point Clouds 

    Maalek, Reza; Lichti, Derek D (University of Calgary, Schulich School of Engineering, Geomatics Engineering, University of Calgary, submittedVersion, 2021-03-14)
    This manuscript presents a new method for fitting ellipses to two-dimensional data using the confocal hyperbola approximation to the geometric distance of points to ellipses. The proposed method was evaluated and compared ...
  • Characterization of Signal Quality Monitoring Techniques for Multipath Detection in GNSS Applications 

    Pirsiavash, Ali; Broumandan, Ali; Lachapelle, Gérard (Schulich School of Engineering, University of Calgary, publishedVersion, 2017-07-05)
    The performance of Signal Quality Monitoring (SQM) techniques under different multipath scenarios is analyzed. First, SQM variation profiles are investigated as critical requirements in evaluating the theoretical performance ...

    The development of acoustic subsurface atomic force microscopy, which promises three-dimensional imaging with single-digit nanometer resolution by introduction of ultrasound actuations to a conventional atomic force ...
  • Facile and rapid synthesis of functionalized Zr-BTC for the optical detection of the blistering agent simulant 2-chloroethyl ethyl sulfide (CEES) 

    Abuzalat, Osama; Homayoonnia, Setareh; Wong, Danny; Tantawy, Hesham R.; Kim, Seonghwan (Royal Society of Chemistry, Schulich School of Engineering, Mechanical & Manufacturing Engineering, University of Calgary, Military Technical College, https://www.rsc.org/journals-books-databases/open-access/green-open-access/, acceptedVersion, 2021-02)
    2-chloroethyl ethyl sulfide (CEES) is a simulant for the chemical warfare agent, bis(2-chloroethyl) sulfide, also known as mustard gas. Here, we demonstrate a facile and rapid method to synthesize a functionalized metal-organic ...
  • Linear regression with an observation distribution model 

    Lichti, Derek D; Chan, Ting On; Belton, David (Springer, Schulich School of Engineering, Geomatics Engineering, University of Calgary, https://www.springer.com/gp/open-access/publication-policies/self-archiving-policy, acceptedVersion, 2021-01-18)
    Despite the high complexity of the real world, linear regression still plays an important role in estimating parameters to model a physical relationship between at least two variables. The precision of the estimated ...
  • Wideband Low-Noise Amplifiers Aiming at Achieving Transistor Fmin 

    Belostotski, Leonid (IEEE : New York, New York, Schulich School of Engineering, Electrical and Computer Engineering, University of Calgary, 2020-12)
    Many RF receivers operate over wide bandwidths and required wideband low-noise amplifiers (LNAs). While there are many wideband LNA topologies available, only some of them are able to achieve noise factors that are close ...
  • Evaluation of Tuner-Based Noise-Parameter Extraction Methods for Very Low Noise Amplifiers 

    Belostotski, Leonid; Haslett, James W. (IEEE : New York, New York, Schulich School of Engineering, Electrical and Computer Engineering, University of Calgary, 2010-01-13)
    This paper compares the performance of source-tuner noise-parameter extraction methods used to measure noise parameters of low-noise amplifiers that have very low (1 dB) noise figures. The methods discussed are known as ...
  • CO2 Gasification of Sugarcane Bagasse Char: Consideration of Pyrolysis Temperature, Silicon and Aluminum Contents, and Potassium Addition for Recirculation of Char 

    Motta, Ingrid Lopes; Arnold, Ross A.; Lopez-Tenllado, Francisco Javier; Filho, Rubens Maciel; Wolf Maciel, Maria Regina; Hill, Josephine M. (Schulich School of Engineering, Chemical & Petroleum Engineering, University of Calgary, University of Campinas, acceptedVersion, 2020-11-24)
    In sugarcane bagasse gasification, char recirculation to the gasifier improves the syngas quality and process efficiency. To determine the effect of char properties on the reaction kinetics, in this work, the pregasification ...
  • Impact of particle size and catalyst dispersion on gasification rates measured in a thermogravimetric analysis unit: Case study of carbon black catalyzed by potassium or calcium 

    Arnold, Ross A.; Motta, Ingrid L.; Hill, Josephine M. (Schulich School of Engineering, Chemical & Petroleum Engineering, University of Calgary, acceptedVersion, 2020-11-19)
    Gasification is often studied in the laboratory using a thermogravimetric analysis (TGA) unit with less than 1 g of sample in order to obtain intrinsic rates. Many studies, however, neglect to consider the impact of particle ...
