Esta categoria de inspeção serve para verificarum conjunto amplo de propriedades da arquitetura e faz uso de múltiplasrepresentações do design, tanto em linguagens formais, quanto informais.Por ser um processo essencialmente manual, é um tipo de análise maiscaro do que os de outros, mas que possibilita também a inspeção embusca de qualidades menos formais do software, a exemplo de escalabilidade,manutenibilidade ou operabilidade. Outra vantagem deste tipo de análiseé a de permitir o uso de representações informais ou parciais do designda arquitetura, além de possibilitar a análise considerando múltiplosobjetivos de múltiplos stakeholders.

Como exemplos de análises baseadas em inspeções,podemos citar alguns métodos de avaliação de arquitetura criadospelo Software Engineering Institute , da Carnegie Melon University : o Software Architecture Analysis Method (SAAM), o Architectural Trade-Off Analysis Method (ATAM) e o método Active Reviews for Intermediate Designs (ARID). Podemos encontrar a descrição desses métodosno livro Evaluating Software Architectures , de Paul Clements et al [link] .

Análise baseada em modelos

Análises baseadas em modelos são menos custosas doque as baseadas em inspeções, uma vez que demonstram maior nívelde automação. Este tipo de análise utiliza ferramentas que manipulamrepresentações da arquitetura com o objetivo de encontrar algumasde suas propriedades. Para possibilitar a manipulação, as representaçõesdevem ser escritas em linguagens formais ou semiformais como ADLs( architecture description languages ou linguagens de descrição de arquitetura), como por exemplo, ACME, SADL eRapide, máquinas de estado finito ou UML.

Esta categoria de inspeção é utilizada na buscade propriedades formais da arquitetura, como corretude sintática ou ausênciade deadlocks e, apesar de seu alto grau de automação, pode necessitar que o arquitetoguie a ferramenta de inspeção utilizada considerando os resultados parciais.Uma desvantagem desta categoria é seu desempenho na análise degrandes sistemas. Uma vez que as representações da arquitetura podemlevar à explosão de estados, a análise de todo o espaço de estadosdo sistema pode ser inviável. Portanto, é comum que apenas partes da arquiteturasejam analisadas – de preferência partes mais críticas.

can someone help me with some logarithmic and exponential equations.
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?

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

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

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?
