The notion of diffusion via a stochastic process has been used as a means to approximate desired underlying probability distributions. An important task in such an application is to design a drift so as to accelerate the convergence. This problem can be cast as a special type of inverse eigenvalue problem where the inverse of a given covariance matrix is to be perturbed by skew-symmetric matric...

Given an arbitrary measure μ, this study shows that the set of norm attaining multilinear forms is not dense in the space of all continuous multilinear forms on L1 μ . However, we have the density if and only if μ is purely atomic. Furthermore, the study presents an example of a Banach space X in which the set of norm attaining operators from X into X∗ is dense in the space of all bounded linea...

The concept of the “marketspace” is a powerful and exciting one. However, the papers which introduced it fail to make some of its key components clear. By analysing a number of examples, identifies the crucial features of the concept. Through considering an example from other sources, the validity of the interpretation being proposed is “tested”. Concludes that firms need to constantly consider...

In addition to the growing complexity of software systems, test effort takes increasing amounts of time and correspondingly more money. Testing costs may be reduced without compromising on software quality by minimizing test sets through optimal selection of test cases and introducing more powerful test tools. Attaining high levels of test automation is the objective. There are problems which m...
