Efficiency and Parallelism: The Challenges of Future Computing by William Dally UBC Electrical and Computer Engineering 2014-02-12 | Part of the ECE Colloquium SeriesWilliam Dally is chief scientist at NVIDIA and the senior vice president of NVIDIA research. He is also Professor (Research) of Electrical and Computer Science at Stanford University. Dally and his Stanford team developed system architecture, network architecture, signaling, routing, and synchronization technology that is found in most large parallel computers today. He is a cofounder of Velio Communications and Stream Processors.The computing demands of mobile devices, data centers, and HPC are increasing exponentially. At the same time, the end of Dennard scaling has slowed the rate of improvement and made all computing power limited, so that performance is determined by energy efficiency. With improvements in semiconductor process technology offering little increase in efficiency, innovations in architecture and circuits are required to maintain the expected performance scaling.The large scale parallelism and deep storage hierarchy of future machines poses programming challenges. Professor Dally will discuss these challenges of efficiency and parallelism in more detail and introduce some of the technologies being developed to address them.

Microfluidic systems for cell-based screening of cancer treatments under controlled hypoxia UBC Electrical and Computer Engineering 2016-07-28 | Tumour hypoxia (low oxygen levels) can impact the effectiveness of cancer treatments. Abnormal blood vessels in tumours can lead to oxygen gradients and chronic and transient (intermittent) hypoxic regions, with hypoxia/reperfusion rates of a few cycles per hour. Transient hypoxia can promote tumour aggressiveness and changes in cell phenotype compared with chronic hypoxia. Including these effects in early in vitro screening stages could yield results more predictive during subsequent in vivo tests. Since state-of-the-art in vitro platforms such as well plates, glass dishes, hypoxia chambers, and even custom stirred hypoxic vessels can’t easily reproduce these effects due to long equilibration times (hours), we use microfluidic devices which offer the potential to control and reproduce more realistic environments due to their smaller size scales.Video showing time-varying fluidic oxygen levels within a microfluidic device. Left: Gaseous oxygen levels supplied to the microfluidic device (red), and average oxygen levels at the bottom of the water-filled cell culture channel (black), measured (using fluorescence microscopy) by the integrated ratiometric optical oxygen sensor films. Fluidic oxygen levels closely follow gaseous oxygen supply, with a fast switching time of less than 10 minutes. Right: False-colour oxygen levels (ranging from 0% (blue) to 10% (red)) measured by the integrated sensor films, overlaid upon a brightfield image of the microfluidic device with trapping structures for 3-D cultures. After equilibration, the oxygen levels are uniform across the width and length of the channel. For more information please see Sensors 2015, 15(8), 20030-20052; doi:10.3390/s150820030.
Tissue engineering 3-D cultures UBC Electrical and Computer Engineering 2016-07-28 | Three-dimensional (3-D) culture can more accurately replicate the natural growth environment for many cells compared to 2-D monolayers. The extracellular matrix (ECM) plays an important role in promoting cell proliferation, differentiation, and complex cell-matrix interactions, including these effects in early in vitro stages of drug screening could yield results more predictive of in vivo assays. In our approach, we generate cell-laden hydrogel beads and incorporate elements of the ECM, including collagen and reconstituted basement membrane matrix, to provide cues from the natural microenvironment. The video demonstrates second harmonic generation imaging shows collagen distribution within the core-shell beads. Optical sections were acquired at 5 µm intervals from the top of the bead to 300 µm into the bead.
Swelling Image | Microfluidic systems for treatment screening under controlled hypoxia UBC Electrical and Computer Engineering 2016-07-27 | Tumour hypoxia (low oxygen levels) can impact the effectiveness of cancer treatments. Abnormal blood vessels in tumours can lead to oxygen gradients and chronic and transient (intermittent) hypoxic regions, with hypoxia/reperfusion rates of a few cycles per hour. Transient hypoxia can promote tumour aggressiveness and changes in cell phenotype compared with chronic hypoxia. Including these effects in early in vitro screening stages could yield results more predictive during subsequent in vivo tests. Since state-of-the-art in vitro platforms such as well plates, glass dishes, hypoxia chambers, and even custom stirred hypoxic vessels can’t easily reproduce these effects due to long equilibration times (hours), we use microfluidic devices which offer the potential to control and reproduce more realistic environments due to their smaller size scales.Video showing the response of an MCF-7 breast cancer tumour spheroid to cyclic hypoxia within a microfluidic oxygen control device. Left: Spheroid size (black) and oxygen level supplied to the control device (red) during exposure to a cycling oxygen profile (cycling between 0%, 3%, and 10% oxygen). Right: Brightfield video of spheroid overlaid with the segmentation (white line) used to calculate the spheroid size plotted on the left. The spheroid increases in size when exposed to 0% oxygen and decreases again when exposed to 3% and 10% oxygen, showing evidence of dynamic swelling and shrinkage during cycling hypoxia.
Inkjet printing of living cells UBC Electrical and Computer Engineering 2016-07-27 | Piezoelectrically actuated inkjet nozzles have been used for printing of suspensions of living cells for numerous applications including tissue engineering and drug discovery. Although inkjet cell printing systems provide high precision droplet volume dispensing capability for a wide range of ink rheology, they do not offer high reliability in the number of printed cells per drop. In addition to non-uniform distribution of cells due to sedimentation and aggregation, the observed deviation from the ideal Poisson distribution is attributed to the unexpected hydrodynamic response of cells inside the nozzle. In our work, we use high speed imaging to visualize the hydrodynamics of cell motion inside the inkjet nozzle. We are tuning the rheological properties of the fluids and studying how they affect the distribution of cells within printed droplets.DropletComparison.aviLeft: cell is dispensed with the dispensed droplet. Right: cell is unexpectedly reflected backward into the nozzle! This phenomenon may reduce printing reliability.

Imaging techniques for tissue engineering and microfluidics UBC Electrical and Computer Engineering 2016-07-27 | The tightly packed cells within a tumour model will scatter light, inducing blurring and low signal intensity when imaging. Improved imaging techniques will be crucial for analyzing how cells interact.We demonstrate a microfluidic platform for high-throughput on-chip optical clearing of breast cancer spheroids using the ClearT2 clearing method. Video showing the monitoring of a fixed MCF-7 breast cancer tumour spheroid during optical clearing using the ClearT2 formamide/PEG clearing protocol. Clearing is conducted within a microfluidic spheroid trapping device to facilitate controlled supply of clearing reagents as well as sample monitoring during the clearing process. Transmitted light imaging (left) and a two-photon fluorescence microscopy slice image (right, showing orange FUCCI fluorescent protein fluorescence within cell nuclei) show the spheroid clearing over time. Cell nuclei in the middle of the spheroid become more visible (brighter as well as better-resolved) after the clearing process. The clearing protocol first causes spheroid shrinkage and subsequent swelling, recovering close to the initial spheroid size.

Smile to Pay? Only if you are joking with Prof. Angela Sasse UBC Electrical and Computer Engineering 2016-04-14 | Passwords as a means of identifying users have 'expired', to borrow a fitting phrase from Wired Magazine. Long and complex passwords have induced password fatigue in users, and almost weekly news of password databases at major online providers being breached does not inspire confidence. 2 factor solutions have been deployed in online banking, but high cost and customer complaints are prompting a re-think. Biometric solutions are rapidly gaining ground for payments, especially on mobile phones - Apple's Touch ID and face recognition in particular. This talk will examine the usability, user acceptance and security issues associated with these forms of authentication.M. Angela Sasse is the Professor of Human-Centred Technology and Head of Information Security Research in the Department of Computer Science at University College London, UK. A usability researcher by training, she started investigating the causes and effects of usability issues with security mechanisms in 1996, and her 1999 'Users Are Not the Enemy' paper (co-authored with Anne Adams) is the most cited Usable Security paper. She is currently the Director of the UK Research Institute for Science of Cyber Security - a virtual multidisciplinary research collaboration conducting empirical studies on the impact of security measures. She was elected a Fellow of the Royal Academy of Engineering in 2015.
Nick McKeown ECE Colloquium UBC Electrical and Computer Engineering 2016-03-03 | Software-Defined Networking (SDN) has been successful because it lets network owners and operators “program” network behavior. Today, owners and operators of large networks take it for granted that they can commission, write or buy software to manage their network. But SDN’s programmability is confined to the network control plane. Conventional wisdom says that if we want the forwarding plane to be programmable, we must pay a large penalty in terms of performance and power. In about 2010, we started to challenge the conventional wisdom and I am now convinced it is no longer true. I will explain why in the talk; and will describe a new breed of programmable high-performance forwarding chips following the PISA architecture (Protocol Independent Switch Architecture). To program PISA devices we will need a domain specific language, in which programmers declare the forwarding behavior they want. P4 is such a language and is gaining wide traction as a way to write portable, target-independent programs to run on PISA devices. In P4, the programmer declares how packets are to be proces sed, and a compiler generates a configuration for a protocol-independent switch chip or NIC. For example, the programmer might program the switch to be a top-of-rack switch, a firewall, or a load-balancer; and might add features to run automatic diagnostics and novel congestion control algorithms. In this talk, I will explain why high performance programmable switches are inevitable, give a brief primer on P4, and explain how this will transform how we program and use the network. Nick McKeown (PhD/MS UC Berkeley ’95/’92; B.E Univ. of Leeds, ’86) is the Kleiner Perkins, Mayfield and Sequoia Professor of Electrical Engineering and Computer Science at Stanford University, and Faculty Director of the Open Networking Research Center.

An Electron Microscope Affordable for Developing-World Clinics? UBC Electrical and Computer Engineering 2016-02-05 | The Peter Wall Institute presents International Visiting Research Scholar Professor R. Fabian Pease, Department of Electrical Engineering, Stanford University The minimum cost for an electron microscope is $50,000, which is clearly unaffordable for most developing-world clinics. However, inspired by the realization of the $1 ‘Foldscope’ microscope, we have been exploring the possibility of making a lower cost electron microscope at around $150. Several radical departures are needed. One is to avoid the need for vacuum pumps, for example, by employing a sealed tube with a thin window for bringing the electrons onto the sample at atmospheric pressure. Another challenge is providing a stable source of 50,000 volts. Prof. Pease will discuss several innovative approaches to create an affordable electron microscope with an image display on a smart phone.Fabian Pease has been a Professor of Electrical Engineering at Stanford University since 1978. He served as a radar officer in the RAF, then studied Natural Sciences & Electrical Engineering at Cambridge University, where he built the 5th scanning electron microscope. At U.C. Berkeley, he continued his research in scanning electron microscopy, then joined Bell Laboratories to work on digital television and electron beam lithography. His current interests include free electron sources for microscopy, lithography and X-ray generation.

ECE Colloquium with Ahmed Tewfik UBC Electrical and Computer Engineering 2015-10-08 | The Role of Information Acquisition in Human Intelligence Amplification | Ahmed Tewfik, U. Texas AustinDecades of research indicate that humans are not rational decision-makers. Our decisions and assessments of situations we encounter and other individuals or groups are sometimes flawed because they are based on a limited acquisition and rational analysis of information, and strongly influenced by our past experiences. The outcomes of decisions negatively impacted by cognitive biases affect individuals, businesses and society. Their impacts can be temporary and mildly annoying, such as buying an unneeded or wrong tablet or triggering an unwarranted fight with a spouse, or long term and costly, such as marrying the wrong person , wrong product or business decision, or creating an environmental disaster. In this talk we review the evidence of cognitive biases in human decision making. We then discuss an emerging mathematical theory of man-machine symbiosis and intelligence amplification. Optimal man machine symbiosis produces better outcomes than those produced by man alone or machine alone. We highlight the challenges that must be solved for optimal man machine symbiosis, formulate solutions to these challenges and conclude with descriptions of initial successes.Ahmed H Tewfik received his B.Sc. degree from Cairo University, Cairo Egypt, in 1982 and his M.Sc., E.E. and Sc.D. degrees from MIT, in 1984, 1985 and 1987 respectively. He is the Cockrell Family Regents Chair in Engineering and the Chairman of the Department of Electrical and Computer Engineering at the University of Texas Austin. He was the E. F. Johnson professor of Electronic Communications with the department of Electrical Engineering at the University of Minnesota until September 2010. Dr. Tewfik worked at Alphatech, Inc. and served as a consultant to several companies. From August 1997 to August 2001, he was the President and CEO of Cognicity, Inc., an entertainment marketing software tools publisher that he co-founded, on partial leave of absence from the University of Minnesota. His current research interests are in cognitive augmentation through man-machine symbiosis and mobile computing, medical imaging and brain computing interfaces. Prof. Tewfik is a Fellow of the IEEE. He was a Distinguished Lecturer of the IEEE Signal Processing Society in 1997 - 1999. He received the IEEE third Millennium award in 2000. He was elected to the position of VP Technical Directions of the IEEE Signal Processing Society in 2009 and served on the board of governors of that Society from 2006 to 2008. He has given several plenary and keynote lectures at IEEE conferences.
