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.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
