| 2:30 pm -3:00 pm | Introduction to CPS Robot Blueprint family Haruhisa Fukano Fujitsu Robotics is an important tool for achieving the SDGs. Workers will be able to focus on decent work and new innovation by improvement of labor productivity , as a result, they can move toward new economic growth. However, there are industries where it is difficult to apply current robotics. For example, agriculture, restaurant, food factory, etc.. The biggest challenge current robotics faces in the industry is how to control elastic and non-uniform object under variable circumstance. To apply robotics to any industry easily, this blueprint family develop and provide open software stack which can achieve the challenge. Introduction to Smart data transaction for CPS Haruhisa FukanoFujitsu Smart Data Transaction for CPS - Akraino - Akraino Confluence Cyber physical systems which combine sensor network with computing to monitor and control the physical environment become popular. The bandwidth of the sensor network depends on use cases. Large amounts of data from large amounts of sensor nodes will pressure the NW bandwidth between edge and clouds. Therefore, we need to have a means to optimize each NW bandwidth according to use cases. This blueprint propose a solution for NW bandwidth optimization. |

| 9:00 am - 9:45 am | Where the Edges Meet, Infra Forms and Apps Land How DevOps driven optimally deployed infrastructure and software will make 5G a reality 5G represents a dramatic technological inflection point, where the cellular wireless network becomes capable of delivering significant improvements in capacity and performance. However, the technology in and of itself, cannot deliver intended service capabilities for the users and their use cases. What is needed is optimally deployed infrastructure on which the promises of technology can be delivered and the software that can orchestrate this infrastructure to enable desired capabilities and performance. This talk will provide an overview of the infrastructure deployment considerations for supporting 5G requirements and how DevOps driven orchestration and automation are becoming an integral part of deployment tools. Oleg Berzin Fellow, Technology and Architecture, OCTO, Equinix; Co-Chair Akraino TSC

HanaHaus Workspace Terms of Use
Below is the HanaHaus "Workspace Terms of Use". Please read and make sure you can comply.
HanaHaus Covid-19 Health Screening
Below is the HanaHaus "Covid-19 Health Screening" doc. Again, please read and make sure you can comply. Updates (current as of March 3rd, 2022). If any info conflicts with the screening doc the updates supersede:
(i) HanaHaus does not check for proof of vaccination
(ii) As of March 2nd 2022, Santa County County rescinded it's indoor mask mandate, with which HanaHaus is complying, so masks are not required upon entry, in general areas like the coffee/snack bar and meeting tables, or inside meeting rooms
Of course wearing a mask may well be appropriate depending on your personal situation and beliefs, so if you want to wear a mask, by all means do so ! Otherwise, if Santa Clara County or HanaHaus rules make you uncomfortable in any way, definitely do not attend in person.
Note in the above screening doc, this text:
"You attest that: You and your guests have not been diagnosed with Coronavirus/Covid-19 and not yet cleared as non contagious by state or local public health authorities."
does not make sense. The text "and not yet" should be "or have been". I have pointed this out to HanaHaus management. Evidently they received basic form text from Santa Clara county and then modified it somewhat, ending up with a contradictory clause.
