Within systems engineering, quality attributes are realized non-functional requirements used to evaluate the performance of a system. These are sometimes named architecture characteristics, or "ilities" after the suffix many of the words share.
There is an essentially unique two-dimensional, compact, simply connected manifold: the 2-sphere. In this case, it is unique up to homeomorphism. In the area of topology known as knot theory, there is an analogue of the fundamental theorem of arithmetic: the decomposition of a knot into a sum of prime knots is essentially unique. [5]
In metaphysics, a universal is what particular things have in common, namely characteristics or qualities. In other words, universals are repeatable or recurrent entities that can be instantiated or exemplified by many particular things. [1]
Like all non-functional requirements and quality attribute [6] requirements, architecturally significant requirements should be specified in a SMART way. Quality attribute scenarios [ 2 ] are one way to achieve the S (specific) and the M (measured) criteria in SMART.
Attributes are closely related to variables. A variable is a logical set of attributes. [1] Variables can "vary" – for example, be high or low. [1] How high, or how low, is determined by the value of the attribute (and in fact, an attribute could be just the word "low" or "high"). [1] (For example see: Binary option)
Features: features are additional characteristics that enhance the appeal of the product or service to the user. Reliability: a key element for users who need the product to work without fail for an adequate length of time. Conformance: is the product made exactly as the designer intended. Durability: a measure of the length of a product’s life.
A new study seemingly upends a long-accepted truth about fingerprints: They are not, a Columbia University undergraduate and his colleagues argue, all unique.
Categorization is a type of cognition involving conceptual differentiation between characteristics of conscious experience, such as objects, events, or ideas.It involves the abstraction and differentiation of aspects of experience by sorting and distinguishing between groupings, through classification or typification [1] [2] on the basis of traits, features, similarities or other criteria that ...
