Summary: Energy storage for electric vehicle is mainly the battery and super-capacitor. Usually a large number of cells care connected in series and parallel in order to provide required voltage and current levels. The balancing is therefore needed to enable each of the cell under equal contribution to the voltage and current. The battery management system (BMS) includes the balancing, other management and monitoring and control system. Today BMS is the most important parts in most of the electric vehicles and there are reports that BMS is a critical parts to avoid any accident of electric vehicle.
The talk presents the recent technology in the energy storage of electric vehicles including Li-ion battery and super-capacitor, cell balancing and BMS, and also introduces a number of different designs of the cell balancing techniques.

Cost: none
RSVP: requested, through website
Event Details:
Summary: Teardowns are powerful tools to gain invaluable insight on how things are designed and built. Critical lessons can be learned from this process to improve our jobs as designers and manufacturers of electronic products. The Apple Watch went from novelty to market leader in just a few weeks. Added to its impressive commercial success, this device is an incredible work of electronic packaging design. In this presentation we will show the details of the Apple Watch teardown, showing its many layers and complexities. We augment the teardown with x-ray images of several parts of the Apple Watch to gain extra insights on how this tightly packaged device is assembled. We will also present other similar teardowns, including cell phones and wearables.

Bio: Bill Cardoso started his first company in Brazil at age 17 and sold it a few years later when invited by the US Department of Energy to work at Fermi National Accelerator Laboratory to do nuclear and high-energy physics research. As the Department Head for Systems Engineering and after a 10-year long career at Fermilab, Bill moved from Chicago to sunny California to start Creative Electron. True to the American Dream, Creative Electron quickly grew from Billโ€™s garage to the largest US manufacturer of x-ray machines for the electronics industry (no longer in his garage). At Creative Electron Bill leads the team of engineers who designs and manufactures x-ray systems that are shipped worldwide. Starting with an associate degree at age 13, Bill has a BS, MS, and PhD degrees in Electrical and Computer Engineering and an MBA from The University of Chicago. Bill is the president of the SMTA San Diego chapter and member of the technical committee for SMTA International, SMTA Counterfeit Conference, and SMTA LED Conference, Components for Military and Space Electronics Conference, SPIE Photonics, and the IEEE Nuclear Science Symposium. He is an IEEE Senior member and the author of over 120 technical publications, a contributor to 2 books, owner of a few patents, and a frequent speaker at technical conferences.

The Technical Challenge of Hate Speech, Incitement and Extremism in Social Media ๐Ÿ—“ ๐Ÿ—บ

Meeting Date: Tuesday, August 30, 2016
Time: 6:00 PM Networking and dinner; 7:00 – 8:30 PM Presentation
Speaker: Dr Andre Oboler, social media expert
Location: Room 3008, CALiT2 Building, UCI, Irvine
Cost: none (dinner sponsored by Gigasavvy)
RSVP: requested, through website
Event Details:
Summary: Despite its pervasiveness in society, social media has been a largely unregulated domain. There have been growing concerns over the use of social media for the purposes of hate speech, incitement and the promotion of violent extremism. These issues have not been sufficiently addressed by social media companies and governments, particularly in Europe, are increasing looking to regulation. The agreement on a โ€œCode of Conduct on illegal online hate speechโ€ signed by the European Commission and Facebook, Twitter, YouTube and Microsoft the end of May 2016 is a sign of this shift.
This talk will introduce the problem of hate speech, incitement and extremism in social media. The technical challenges in measuring and responding to these problem will then be discussed, along with some of the technical solutions which have been created. The ethical obligations of Software Engineers in light of these problems will also be considered.

Bio: Dr. Andre Oboler is CEO of the Online Hate Prevention Institute an Australian charity combating racism, bigotry and extremism in social media. He also serves as an expert on the Australian Government’s Delegation to the International Holocaust Remembrance Alliance, co-chair of the Working Group on Antisemitism on the Internet and in the Media for the Global Forum to Combat Antisemitism, and as a Vice Chair of the IEEE Computer Society’s Member and Geographic Activities Board. Dr Oboler holds a PhD in Computer Science from Lancaster University (UK), a Juris Doctor from Monash University (Australia) and completed a Post Doctoral Fellowship in Political Science at Bar-Ilan University (Israel). His research interests include empirical software engineering, process improvement, hate speech in social media and the social implications of technology.

“Body-on-a-Chipโ€ ๐Ÿ—“

Meeting Date: Wednesday, November 9, 2016

Human organs and their associated functions are, with few exceptions, 3-Dimensional, and so it is hardly surprising that 2D cell culture systems often do a poor job at replicating human biology. It is only the simplicity of 2D systems that has maintained their popularity for so long. We are changing this dynamic โ€“ we can now create 3D tissues in the lab that share many of the characteristics of organs in the body. Most importantly, the tissues receive their nutrients through living blood vessels, just as they do in the body. This is a unique platform โ€“ we are the only lab in the world able to do this. We are creating multiple organs, including pancreas, brain, liver and heart, which we will use to study diseases such as Diabetes, Alzheimerโ€™s disease and Heart Failure. In addition, we have created multiple types of micro-tumors, including colon, breast, prostate and melanoma, which we are now using for novel drug screening

Dr.Hughes has extensive experience in the field of vascular biology and the process of angiogenesis. In particular, his lab has studied the role of notch signaling in vascular development and we were the first to demonstrate the role of notch in regulating tip cell function during angiogenic sprouting. His lab has recently published on the role of the transcription factor slug in angiogenesis, and are working on wnt regulation of vascular assembly. More recently, in collaboration with Drs. Steve George and Abe Lee he has also been focusing on novel drug-screening platforms, including โ€œtumor-on-a-chipโ€ microfluidic devices. This has been partly driven by their belief that mice are often inadequate models for some aspects of human biology. He has worked with Program PI and project Co-I Dr. Waterman on several projects related to tumor angiogenesis and wnt signaling, and has co-mentored a student with PI Dr. Lowengrub. He is the co-director of the OncoImaging and Biotechnology (OIB) Program โ€“ part of the NCI-designated Comprehensive Cancer Center at UCI โ€“ and Chair of the Department of Molecular Biology & Biochemistry. He has a joint appointment in Biomedical Engineering, and is Interim Director of the Edwards Lifesciences Center for Advanced Cardiovascular Technology. He works extensively with the rare disease non-profit, cureHHT (formerly HHT Foundation International), and is Chair of their Global Research and Medical Advisory Board. Dr. Hughes was recently elected a Fellow of AAAS. He has mentored 13 Ph.D. students doing their thesis work in his lab, numerous rotation students, and several post-doctoral fellows. Several of these are now running their own research programs. Dr.Hughesโ€™ experience in the Cancer Center OIB program and in the BME department have been vital to his research success.

Speaker: Dr Andre Oboler, social media expert

RSVP: requested, through website
Event Details:
Summary: Having found that traditional software engineering approaches and tools were not used by academic researchers in the United States and Australia, a new Software Development Life Cycle (SDLC) was created to tailor software engineering more appropriately to this environment. This talk introduces the ideals embedded in the new SDLC and explains how they were instantiated in a three-year experiment involving multiple researchers on independent projects. The new approaches were shown to have a significant impact when results were compared to a control group. The talk will introduce some of the ideas and tools which led to this impact.
