    Lens questions

  1. Assess the manifest complexity of the technology in question. For example, what is the manifest complexity of windmills? (Do they present tightly coupled systems that lead to unpredictable breakdowns?) Which is more manifestly complex, nuclear reactors or windmill turbines?
  2. Assess the concealed complexity . For example, do the operating procedures of windmills conceal complexity? Do nuclear reactors conceal complexity in the complicated regulation process that has developed between manufacturers and the Nuclear Regulatory Commission? (Maybe, complexity is concealed in the divergence between formal and informal regulatory procedures, the latter having evolved as the NRC has been "captured" by reactor manufacturers.) See Ford
  3. Technological Imperative : Does the technology redefine or displace basic human needs or basic values? Does it require that we adopt ourselves to it?
  4. Reverse Adaptation : Does the technology require reverse adaptation? If yes, are there any viable "work around" strategies that could be implemented to align better the technology's needs with our own.

What you are going to do

    Exercise one: construct a socio-technical system grid

  • Choose a test case from above. (The alternatives include Cogentrix, Copper Mining, Windmills, and Laptops.)
  • Read the module, Socio-Technical Systems in Professional Decision-Making, and modify the STS table for Puerto Rico to fit the test case you are using.
  • Identify the values embedded in the technology of your test case and the STS you have modeled.
  • Identify any possible value mismatches between the technology to be introduced and the underlying STS.

    Exercise two

  • Select two of the lenses outlined above.
  • Examine your test case under the first lens by answering the questions. Give a global assessment of whether your test case technology is acceptable under the lens.
  • Examine your test case under the second lens by answering the questions. Give a global assessment of whether your test case technology is acceptable under this second lens.
  • Compare the results of the two lenses. Discuss areas of divergence between the two lenses. Discuss the areas of convergence.

Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
