Swine flu and sensor-cloud computing

In these days, swine flu outbreak is a hot topic. To detect swine flu patient, a lot of quarantine officers work hard.

I read the following paper about sensor-cloud computing (in other words, sensor-network).

A framework of sensor-cloud integration opportunities and challenges
Mohammad Mehedi Hassan, et. al.
Our primary goal is to facilitate connecting sensors, people and software objects to build community-centric sensing applications. However, the computational tools needed to launch this exploration may be more appropriately built from the data center "Cloud" computing model than the traditional HPC approaches.

I thought, if mobile career integrates the sensor-cloud computing and thermo-sensor phone, it's easy to prevent this outbreak. I'm not sure there is a cell phone with thermo-sensor, but the thermo-sensor itself was already developed such as ROHM BDJ1HFV ( [in Japanese]).

As cloud computing era is just started, this sort of cloud application is appearing. I'm looking forward to see them.

Do Tokyo dreams of Silicon Valley?

The following topic is quite interesting.

Where do you think is the next Silicon Valley?

There are similar technology hubs, such as Bangalore in India and Zhongguancun in China.
I guess, there is a good possibility that Tokyo will be the tech hub. A list of pro and con is;


  • Educational institute (e.g. Tokyo Univ. )
  • High-speed networks. Not only 1Gbps optic cables, but 2.3Mbps mobile infrastructure
  • Compliance of Intellectual Property
  • A cost of hiring. It's cheaper than Silicon Valley.
  • English, English, and English. It's mandatory.
In my mind, there is no need to create Tokyo Silicon Valley physically. I mean, a source of SV is engineer's network and a sense of tech relevancy. (Venture capitals are important players, but I put aside it purposely.) These sources are getting shift into Web through useful web services, such as SNS, wiki, etc. I wonder, this trend could be Web Silicon Valley.

Japanese engineers has skills, but they has lost the sense. So a first step toward Web silicon valley including Tokyo is jumping into web tech community through English web services.

Study report: "Above the Clouds: A Berkeley View of Cloud Computing."

UC Berkeley, RAD Lab releases a study report about cloud computing.

"Above the Clouds: A Berkeley View of Cloud Computing."

What's interesting about their approach is that they tried to quantify an economic value of cloud computing; their model

Even this approach is quite simple, it's a good idea for further discussion.
