The Absolute Error Power Detectors

Time & Date: 3:30pm-4:30pm, Thursday June 1, 2017
Location: EME 1101, UBC Okanagan campus
Registration is open now:

Talk Abstract:
It is well known and fundamental that the matched filter is the optimal detector for a signal immersed in additive white Gaussian noise. The matched filter is a continuous-time structure and always performs better than digital matched filters, which are optimal structures for detecting signals in additive white Gaussian noise based on a number of independent samples of the signal-plus-noise. In the case of non-Gaussian noise, only one other optimal detection structure is known, and that is the optimal (continuous-time) detector for signals immersed in Laplace noise. Meanwhile, the fundamental Gaussian distribution is a special case of the more flexible and descriptive generalized Gaussian distribution (GGD). In this talk, we derive the optimal detector for a signal immersed in additive GGD noise, which we dub the generalized matched filter. This detection scheme finds the absolute value of the difference between a replica of the transmitted signal and the received signal-plus noise, raises this absolute error to the βth power, and then integrates the resulting signal. This detection structure can, therefore, also be referred to as the absolute error power detector. We show that the matched filter is a special case of the absolute error power detector for GGD parameter β = 2, the Gaussian noise case, and that the optimal detector for Laplace noise is also a special case when β = 1. The optimal probability of error for binary signaling in additive white generalized Gaussian noise is assessed. The fundamental structure is also optimal for higher-level modulations after straightforward extensions.

How to Write an IEEE Style Paper and Get it Published?

Time & Date: 11am-12pm, Monday June 5, 2017
Location: EME 1101, UBC Okanagan campus
Registration is open now:

Talk Abstract:

Institute of Electrical and Electronics Engineers (IEEE) is world’s largest professional association which is best known, among other engineering disciplines, for its high quality flagship journal and conference publications. For electrical engineering graduate students and researchers, it is increasingly important to publish their research findings in core IEEE journals and conferences. However, most top IEEE journals and conferences typically have acceptance rate at 35% or much less, and it is also rare that a manuscript receives an outright acceptance. In this talk, I will introduce basic elements of an IEEE style paper, and offer some personal tips and strategies on how to improve the odds of acceptance. The goal of this presentation is to provide the proper guidance to the beginning graduate students so that, with some practice, they can write an IEEE style paper with high confidence. These graduate students can then focus more on the technical contributions of their work.

Automatic generation of 3D building models

Time & Date: 5 pm—6:00 pm, Monday, March 20th, 2017
Location: E 102, 1000 KLO Rd., Okanagan College, Kelowna, BC
Registration is open now:

Talk Abstract: A 3D urban model is an important information infrastructure that can be utilized in several fields, such as, urban planning and game industries. However, enormous time and effort have to be spent to create 3D urban models, using 3D modeling software such as 3ds Max or SketchUp. In our research we will employ automatic generation of 3D building models through integrating GIS (Geographic Information System) and CG (Computer Graphics). An integrated system is proposed for automatically creating 3D building models from building polygons (building footprints) on a digital map. Since most building polygons’ edges meet at a right angle (orthogonal polygon), a complicated orthogonal building polygon can be partitioned into a set of rectangles. The integrated system partitions orthogonal building polygons into a set of rectangles and places rectangular roofs and box-shaped building bodies on these rectangles. This proposal seeks to implement a novel approach to 3D building model construction for rapid assessment of roof damage and insurance liability in the aftermath of natural disasters.

The research will achieve two objectives:

  1. The integration of GIS and 3DCG (3D Computer Graphics) components in a new extension for the ArcGIS platform that generates both simple and complex 3D house models from building footprints (building polygons).
  2. Automated generation of simple and complex roof geometries for rapid roof area damage reporting by length measurements and area calculations of all roof surfaces. In addition to the application to the assessment of roof damage, this system can be applied to BIM (Building information modelling: 3d building model whose parts are linked to each attribute, and by which collision detection between parts can be made).

Talk Abstract: Millimeter-wave signals span the frequency range of 30 GHz to 300 GHz, corresponding to a wavelength range of 10 mm to 1 mm. Signals at these frequencies can easily penetrate inside dielectric materials and composites and interact with their inner structures. The relatively small wavelengths and wide bandwidths associated with these signals enable the production of high spatial-resolution images of materials and structures. Incorporating imaging techniques such as lens-focused and near-field techniques, synthetic aperture focusing, holographical methods based on robust back-propagation algorithms with more advanced and unique millimeter wave imaging systems have brought upon a flurry of activities in this area and in particular for nondestructive evaluation (NDE) applications. These imaging systems and techniques have been successfully applied for a wide range of critical NDE-related applications.

Although, near-field techniques have also been prominently used for these applications in the past, undesired issues related to changing standoff distance have resulted in several innovative and automatic standoff distance variation removal techniques. Ultimately, imaging techniques must produce high-resolution 3D images, become real-time, and be implemented using portable systems. To this end and to expedite the imaging process while providing a high-resolution images, the design and demonstration of a 6″ by 6″ one-shot, rapid and portable imaging system (Microwave Camera), consisting of 576 resonant slot elements, was completed in 2011. Subsequently, efforts were expended to design and implement several different variations of this imaging system to accommodate one-sided and mono-static imaging, while enabling 3D image production using non-uniform rapid scanning of an object, as well as increasing the operating frequency into higher millimeter wave frequencies. These efforts have led to the development of a real-time, portable, high-resolution and 3D imaging microwave camera operating in the 20-30 GHz frequency range which was recently completed. This presentation provides an overview of these techniques, along with illustration of several typical examples where these imaging techniques have effectively provided viable solutions to many critical NDE problems.

Speaker Biography: R. Zoughi received his B.S.E.E, M.S.E.E, and Ph.D. degrees in electrical engineering (radar remote sensing, radar systems, and microwaves) from the University of Kansas where from 1981 until 1987 he was at the Radar Systems and Remote Sensing Laboratory (RSL).

Secure Context Detection in Smartphones

Secure Context Detection in Smartphones

Time & Date: 5:30 pm–6:30 pm, Thursday, February 16th, 2017
Location: EME 1151, UBC, Okanagan Campus, Kelowna, BC

Talk Abstract: The availability of powerful smartphones and the necessity of security in mobile devices have made researchers propose multiple security modes (e.g., home, office, outdoor, and financial) for such devices. In each mode, a user can install a different set of apps. However, in most of the cases, the user has to select the mode manually. If we can sense the smartphone’s security context accurately, then it is possible to switch between different security modes automatically. Also, smartphone operating systems are becoming ubiquitous. As a result, mobile apps need to behave differently based on the security context (e.g., not sending the data if the network is insecure). In this talk, we focus on sensing different security parameters (e.g., location, is-network-encrypted) and calculating the security context from the parameters. We also talk about a security context management framework that maintains a cache of security contexts and parameters to be used by the operating system and third-party applications. As detecting contexts requires the use of power-hungry smartphone sensors, a comprehensive framework for sharing security parameters among various applications can be beneficial in terms of energy and other resource expenses.

Speaker Biography: Md Shahrear Iqbal is a Ph.D. candidate in the School of Computing, Queen’s University,Canada, where he is a member of the Queen’s Reliable Software Technology (QRST) research group. He also holds a faculty position in the Department of Computer Science and Engineering (CSE) in Bangladesh University of Engineering and Technology (BUET), Bangladesh.

Data Analytics in Educational Institutions: Building a Predictive Model for Student Enrolment


McCall Milligan, Jim Nastos and
Jan O’Brien

Department of Institutional Research, Okanagan College

Data Analytics in Educational Institutions:
Building a Predictive Model for Student Enrolment

 Time & Date: 4pm–5pm, Wednesday, December 7th, 2016
Location: E103, Okanagan College, 1000 KLO Rd., Kelowna, BC V1Y 4X8

Talk Abstract: Now more than ever, planning and decision-making is data, rather than gut, driven. While there are many existing models for regression, prediction and learning, choosing an appropriate model involves understanding the associated data deeply. Often, choosing a standard model is still insufficient if the analyst is not customizing their model to handle the intricacies of their data.

We describe our development process of a Markov chain and Dynamic Markov Chain-based model for predicting college enrolments. The model is compared and contrasted against previously-attempted models. We include a demo of using our interface into the model, which allows for roughly 600 configurations of parameters, and many additional override value options.

The ideas presented here are applicable to many dynamical systems involving population migration in a discrete-time process.

Speaker Biography: Jim Nastos earned his PhD from UBC Okanagan in Interdisciplinary Studies. He is currently a College Professor of Computer Science at Okanagan College, and previously worked as an Institutional Research Data Analyst at Okanagan College, a math and computer science lecturer at the UBCO and a math lecturer at the UAlberta. His academic research has been published in mathematics, computer science, physics, social networks, bioinformatics and marketing venues.

McCall Milligan earned his bachelor of Applied Mathematics at UBC Okanagan. He will be entering an MSc program in financial modeling and risk analysis in 2017. McCall is currently working as an Analyst at Okanagan College in the Institutional Research and Planning office.

Jan O’Brien is Manager of Institutional Research and Planning at Okanagan College. She has been in higher education for over 20 years, in Faculty, co-op education and administration.
