PPT on CDMA technology and components

This post includes a PPT on CDMA technology.


Some points in the ppt file are listed below:

Upon completion of this course, you will have an understanding of the following concepts:

• CDMA and other access technologies
• CDMA coding, forward, and reverse channels
• Vocoding, multiplexing, and power control
• Components that comprise a CDMA system
• CDMA messaging and call flow

Why CDMA?

• CDMA is the technology of choice for both 800 MHz Cellular and 1900 MHz PCS service providers
• CDMA satisfies CTIA Users’ Performance Requirements
• CDMA provides high capacity (many times the capacity of AMPS)
• CDMA provides privacy through its coding scheme

The rise of the Bots Robots Surgeons and Disruptive Technology

If youre in Auckland next Wednesday evening (22nd Ocotober) you might be interested in attending a free public lecture by Dr Catherine Mohr titled "The rise of the Bots: Robots, Surgeons and Disruptive Technology." Surgery has been changing rapidly in the last 10 years with the advent of surgical robots and the increase in minimally invasive surgical techniques. Dr Catherine Mohr will talk about these changes in surgical practice, the technologies that underlie them, and what we might see in the future as new technologies such as earlier diagnostics, advanced imaging and regenerative medicine bring disruptive changes to healthcare around the world.
Dr Mohr is Vice President of Medical Research at Intuitive Surgical, where she evaluates new technologies for incorporation into the next generation of surgical robots. She also is a consulting Assistant Professor in the department of Surgery at Stanford School of Medicine and on the Medicine and Robotics Faculty at Singularity University. A frequent speaker on the topics of surgical robotics, innovation and the importance of science,at national and international conferences, she is also the author of numerous scientific publications and the recipient of multiple awards. You can get a ticket for the lecture here.

The World Parks Congress Using technology to protect our natural environment

Posted by Dave Thau, Developer Advocate for Google Earth Engine and Karin Tuxen-Bettman, Program Manager, Google Earth Outreach

(Cross posted on the Official Google Australia Blog)

This week, thousands of people from more than 160 countries will gather in Sydney for the once-in-a-decade IUCN World Parks Congress to discuss the governance and management of protected areas. The Google Earth Outreach and Google Earth Engine teams will be at the event to showcase exemplars of how technology can help protect our environment.

Here are a few of the workshops and events happening in Sydney this week:

• Monday, November 10th - Tuesday, November 11th: Over the last couple of days, the Google Earth Outreach and Earth Engine teams delivered a 2-day hands-on workshop to develop the technical capacity of park managers, researchers, and communities. At this workshop, participants were introduced to Google mapping tools to help them with their conservation programs. 
• November 13 - 19: Google will be at the Oceans Pavilion inside the World Parks Congress to demonstrate how Trekker, Street View and Open Data Kit on Android mobile devices can assist with parks monitoring and management. 
• Friday, November 14, 9:30-10:30am: Join a Live Sydney Seahorse Hunt in Sydney Harbour, via Google Hangout, with Catlin Seaview Survey and Sydney Institute of Marine Science. Richard Vevers, Director of the Catlin Seaview Survey, will venture underwater to his favorite dive site and talk with experts about the unique marine life (including seahorses!) that explorers can expect to find around Sydney. Tune in here at 10:30am to catch all the action. 
• Saturday, November 15th, 8:30am: Networking for nature: the future is cool. Hear about how technology-driven ocean initiatives can help us better understand and strengthen our connection with our natural environments. WPCA-Marine’s plenary session will includes presentations by Sylvia Earle and Mission Blue, Catlin Seaview Survey, Google, Oceana, and SkyTruth. The session will also feature leading young marine professionals Mariasole Bianco and Rebecca Koss. 
• Saturday, November 15th, 12:15pm: We’ll be hosting a panel discussion on using Global Forest Watch to monitor protected areas in near-real-time. Global Forest Watch is a dynamic online alert system to help park rangers monitor and preserve vast stretches of parkland.
• Saturday, November 15th, 1:30 - 3:00pm: At the Biodiversity Pavilion join Walter Jetz from Yale and Dave Thau from Google for a presentation on Google Earth Engine and The Map of Life. The presentation will showcase how Google Earth Engine is being used in a variety of conservations efforts - including monitoring water resources, the health of the worlds forests, and measuring the impact of protected areas on biodiversity preservation. We will also announce a new global resource from The Map of Life for mapping and monitoring biodiverse ecosystems. 

We believe that technology can help address some of our world’s most pressing environmental challenges and we look forward to working with Australian conservationists to integrate technology into their work.

You can find us at the Oceans Pavilion inside the World Parks Congress, where we will be joined by our environmental partners including The Jane Goodall Institute, The World Resources Institute and The Map of Life.

We hope to see you at one of our events this week!
