Title of the Talk:

Online Learning and Management for Edge Computing in IoT

Abstract:

Internet-of-Things (IoT) envisions an intelligent infrastructure of networked smart devices offering task-specific monitoring and control services. The unique features of IoT include extreme heterogeneity, ubiquitous low-power devices, and unpredictable dynamics also due to human participation. The need naturally arises for foundational innovations in network design and management to allow efficient adaptation to changing environments, and low-cost service provisioning, subject to stringent latency constraints. To this end, the overarching theme of this talk is a unifying framework for online learning and management policies in IoT through contemporary communication, networking, learning, and optimization advances. From the network architecture vantage point, the unified framework leverages a promising architecture termed fog that enables smart devices to have proximity access to cloud functionalities at the network edge, along the cloud-to-things continuum. From the algorithmic perspective, key innovations include online approaches adaptive to different degree of nonstationary in IoT dynamics, and their scalable implementation under limited feedback that motivates bandit approaches, along with local information exchanges that enable distributed approaches. The outlined framework can serve as a stepping stone that leads to systematic designs and rigorous analysis of task-specific learning and management schemes for IoT.

Design for Human Experience and Expression at the HCT Laboratory

Abstract:

Research at the Human Communications Technology (HCT) laboratory (hct.ece.ubc.ca) has been targeting design for human experience and expression. In this presentation, I’ll start with a discussion of gesture-to-speech and voice explorations, including Glove-TalkII and the Digital Ventriloquized Actors (DIVAs). I’ll connect these to other explorations of the new interfaces for musical and visual expression that we have created.  I will discuss our work on modelling human anatomy and function, such as speaking, chewing, swallowing and breathing with biomechanical models using our toolkit Artisynth (www.artisynth.org) and our real-time acoustic wave synthesis engine using an accelerated 2D finite-difference, time domain (FDTD) approach. This work is motivated by our quest to make a new vocal instrument that can be controlled by gesture. I’ll discuss some of the activities we have been doing on some new 3D displays: pCubee and Spheree. Finally, these investigations will be used to support a theory of designing for intimacy and discussions of perspectives on human computer interaction for new experiences and forms of expression.

Title of the Talk:

Silicon Photonics: Smaller, Cheaper, Faster.

Abstract:

As the name suggests, “silicon photonics” refers to technologies that use optical components fabricated in silicon (using techniques developed for fabricating silicon electronic circuits) for signal processing and transmission applications. Silicon photonics has been seen to be a promising technology since the 1980s; in fact, it has been viewed as a potentially disruptive technology for nearly two decades. While there are several silicon photonic platforms, those based on silicon-on-insulator (SOI) technologies are most widely used. The “nano-photonic” devices that are formed on SOI platforms have large refractive index contrasts between their silicon “nanowire” waveguide cores and the surrounding media and, as a result, allow many orders of magnitude reduction in the on-chip real estate required by integrated optical components fabricated on SOI as compared to their traditional counterparts. Two benefits of this significant reduction in component size (as well as the ability to leverage standardized processing techniques) are an even greater reduction in the cost of each component and a manifold increase in the number of components that can be fabricated on a nano-photonic integrated circuit. Recent developments in high-speed modulators and photodectors for use on SOI platforms, combined with the increased ability to integrate multiple components on a single chip that is provided by these platforms, have enabled the designs of nano-photonic integrated circuits that have extremely large bandwidths and aggregate data rates. In addition to being smaller, cheaper, and faster, such silicon nano-photonic integrated circuits offer the high reliabilities associated with silicon-based technologies. This presentation will review work currently being conducted by numerous reseach groups and companies, including our silicon photonics research group here at UBC, that is moving silicon photonics toward realizing its long promised potential.

Title of the Talk:

Non-Orthogonal Multiple Access in 5G Wireless Networks

Abstract:

Non-orthogonal multiple access (NOMA) is a spectrally efficient multiple access technique, which has the potential to meet the rapidly increasing traffic demand of the fifth generation (5G) wireless networks. With NOMA, multiple users can be simultaneously served by the same base station via exploiting the power domain in addition to the time and frequency domains. However, by sharing the frequency channel and transmit power among the paired NOMA users, NOMA may not always achieve better performance than orthogonal multiple access (OMA). In this talk, the basic idea of NOMA transmission is discussed. For downlink NOMA transmission with dynamic traffic arrival for spatially random users, two variants of NOMA schemes, namely opportunistic NOMA and cooperative NOMA with full-duplex relaying, are proposed to enhance the stable throughput region, which is characterized by using tools from queuing theory and stochastic geometry.  Results show that the sum rates of the proposed NOMA schemes over OMA are higher when users having more diverse target data rates are paired.

Title of the Talk:

Satellite Observation for Coastal Ocean and Inland Waters.

Abstract:

The Canadian Space Agency (CSA), in collaboration with other Canadian government departments and international partners, has been developing advanced satellites for coastal ocean and inland waters. Canada’s extensive coastal areas and inland water bodies offer great value to Canadians. Meanwhile, they are under increasing pressures from direct human impacts and are experiencing unprecedented changes from modifications to our climate. Satellite observations have played an important role in the monitoring and study of the oceans and inland waters. In this talk, Dr. Qian will briefly present the development on strategies and sustainability of ocean and inland waters, then the basic principle of ocean color satellites, followed by the Canadian satellites for ocean and waters, and finally the main ocean satellites developed in the world.

Title Of The Talk: Vector Microsensors for Acoustic and Optical Signals

Abstract: In many applications, it is necessary to locate a signal source. Various techniques have been employed that employ models for signal propagation through a media and often rely on some information about the source, such as signal strength or time-of-flight. Locating an unknown source is typically based on estimating the propagation vector, and hence, requires extraction of both the amplitude and direction information from the received signals.

In this talk, we will discuss the applications of micro-sensors for two such cases. In the first case, the goal is to detect an underwater object based on sonar signals received by an array of transducers. The rationale and challenges of using micromachined devices for this application will be presented. For the second case, the goal is to improve the safety of humans when they collaborate on factory floors with robots. Considering humans as infrared sources, we are developing sensors that reveal the direction of an incoming beam of light, and hence, can be used to locate the humans around the robots with the goal of avoiding potential collisions.
