Usability is an important quality attribute for APIs. To create APIs with good usability, appropriate measurement methods are needed. But currently available methods are cost- and time-expensive and the results are not objective and therefore hard to quantify. API design guidelines give a good overview about important usability factors, but lack a scientific basis. When looking at scientific API usability...
While usability has proven to be an important software quality attribute, its application to APIs is still rather uncommon. Available methods for measuring software usability show significant disadvantages when applied to APIs, like the need for test users and experienced evaluators. This makes it difficult to evaluate the usability of software components, as well as to compare different software...
The Co x Zn 1−x Al 2 O 4 system (x=0; 0.1; 0.3; 0.5; 0.7; 0.9 and 1) was synthesized by the polymeric precursor method and characterized by the techniques XRD, TG-DTA, IR, UV–vis and colorimetry. The XRD patterns displayed the characteristic peaks of the spinel structure and a good crystallinity. The DTA curves showed an exothermic peak corresponding to the enthalpy...
