We review the definition of evolvability as it appears on the literature. In particular, the concept of software evolvability is compared with other system quality attributes, such as adaptability, maintainability and modifiability.

Crystalline surface layer proteins (S-layer proteins) have considerable potential for the crystalline arrays in biotechnology, biomimetics and nonlife applications, including areas such as microelectronics and molecular nanotechnology. The extensive application potential of surface layers in nanobiotechnology is according to the particular inherent attributes of the single molecular arrays cons...

We consider a sorting (classification) problem in the presence of multiple attributes and criteria, called the MA&C sorting problem. It consists in assignment of some actions to some pre-defined and preference-ordered decision classes. The actions are described by a finite set of attributes and criteria. Both attributes and criteria take values from their domains; however, the domains of attrib...

in this paper, we examine the effects of thermal radiation on co2 emission and o2 depletion in an exothermic reactive slab of combustible materials with uniform surface temperature. the governing equations for the nonlinear heat and mass transfer problem are derived and solved numerically using runge-kutta-fehlberg method with shooting technique. numerical expressions for temperature field, co2...
