OPTIMAL SIGNAL ENCODING BASED ON EXPERIMENTAL DATA

École de technologie supérieure

A method and apparatus for optimal signal encoding based on reference data relating encoded-signal characteristics to encoding parameters are disclosed. Reference vectors of encoding parameters and corresponding measurements of encoded-signal characteristics are used to establish a functional relationship between each characteristic and the encoding parameters. Candidate vectors of encoding parameters are identified based on user-defined boundaries of both the encoding parameters and...

DNA CONFORMATIONAL SWITCHES AS SENSITIVE ELECTRONIC SENSORS OF ANALYTES

Simon Fraser University

The electrical conductivity of DNA and other oligonucleotide constructs is dependent on its conformational state. Such a dependence may be harnessed for the electronic sensing of external analytes, for instance, adenosine. Such a DNA sensor incorporates an analyte receptor, whose altered conformation in the presence of bound analyte switches the conformation, and hence, the conductive path between two oligonucleotide stems, such as double-helical DNA. Two distinct designs for such sensors...

METHODS FOR MATCHING XML DOCUMENTS

University of Alberta

Methods, systems, and devices related to determining differences between XML documents. Two XML documents to be compared are first each decomposed into ordered labelled trees. Sets of operations which convert one tree into the other tree are then determined and a cost function is applied to each set of operations. The set of operations with the lowest cost is then selected. The cost function uses an affine-cost policy which adjusts a cost of each operation based a context in which the...

WEARABLE RESPIRATION SENSOR AND RESPIRATION MONITORING SYSTEM

Laval University

There is described a wearable respiration sensor generally having a stretchable textile substrate to be worn around a user's torso; and a dipole antenna having two flexible conductive elements extending in opposite directions from a center, relative to a dipole axis, and being secured to the stretchable textile substrate, each of the two flexible conductive elements having a proximate end near the center, a distal end away from the center, and a curved portion curving away from and back...

METHODS AND SYSTEMS FOR DETERMINING MOTION VECTORS IN A MOTION ESTIMATION PROCESS OF A VIDEO ENCODER

École de technologie supérieure

Methods and systems for determining motion vectors in a motion estimation process of a video encoder are provided. Embodiments of the present invention provide a solution for the problem of unnecessary cost function evaluations, found when combining the successive elimination method with a predetermined list of candidate motion vectors search ordering. In order to solve this problem, embodiments of the present invention provide an adaptive scan ordering of block matching candidates within a...

TREATMENT OF A PRION DISEASE

University of Calgary

There is described compounds, compositions, methods, and uses, of treating a subject having, suspected or having, or at risk of having, a prion disease, comprising: administering a cholesterol 24-hydroxylase (CH24OH)-activating compound.

SYSTEMS, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR PROVIDING VIDEO-PASSWORDS FOR USER AUTHENTICATION

University of Ontario Institute of Technology

This invention is related to authentication schemes utilizing advertising video-passwords, which require the user to watch and remember parts of a given advertisement video. Different embodiments of the invention can utilize just time reference point information, or can optionally include grid element, click point, tag phrase, or a combination of both click point and tag phrase information. A reference video-password is defined based on the time reference point information, and optionally...

BIOMARKERS FOR MYCOBACTERIUM AVIUM PARATUBERCULOSIS (MAP)

University of Guelph

Described are methods and products useful for identifying subjects with Mycobacterium avium subspecies paratuberculosis (MAP). A number of protein antigens secreted into culture filtrate by MAP are identified and binding proteins selective for these antigens are demonstrated to be useful for detecting subjects with MAP infections including subjects with Johne's disease.
