Software testing is the process used to measure the quality of developed computer software. It exhibits all mistakes, errors and flaws in the developed software. In this paper, the three most prevalent and commonly used software testing techniques for detecting errors are described and compared, they are: white box testing, black box testing and grey box testing. Keywords— Black box, Demonstrat...

the alternative double bonds and conjugation in the polyene compounds are one of the main properties in these compounds. each carbon-carbon bonds in a polyene compound along the chain has appreciable double-bond character. the p-electrons are therefore not localized but are relatively free to move throughout the entire carbon skeleton as an one-dimensional box. the skeleton be considered as a r...

in this research a numerical analysis using plaxis program has been carried out to investigate the behavior of buried concrete box culverts different parameters including load types, loading locations, culvert dimensions, underlying soil specifications, and the coefficient of earth pressure- at- rest. for modeling purpose, patch loading of rtuck or military tank has been substituted to an equiv...

PAMDI is an electromechanical music controller based on an expansion of the common metal music boxes. Our system enables an augmentation of a music box by adding different musical channels triggered and parameterized by natural gestures during the “performance”. All the channels are generated from the original melody recorded once at the start. We made a platform composed of a metallic structur...

In the field of e-learning, a popular solution to make teaching material reusable is to represent it as learning object (LO). However, building better adaptive educational software also takes an explicit model of the learner’s cognitive process related to LOs. This paper presents a three layers model that explicitly connect the description of learners’ cognitive processes to LOs. The first laye...
