The Bottom Up Approach is Not Always the Best Processing Method: Dense α-Al2O3/NiAl2O4Composites

Extrusion of YAG Tubes Shows that Bottom-up Processing is Not Always Optimal

Is the Best Fitting Curve Always Unique?

is is a continuation of our paper [1] where we studied the problem of existence of the best �tting curve. Here we deal with its uniqueness. Our interest in these problems comes from applications where one describes a set of points PP1,... , PPnn (representing experimental data or observations) by simple geometric shapes, such as lines, circular arc, elliptic arc, and so forth. e best �t is ac...

The Simplex Method is Not Always Well Behaved

This paper deals with the roundingerror analysis of the simplex method for solving linear-programming problems. We prove that in general any simplex-type algorithm is not well behaved, which means that the computed solution cannot be considered as an exact solution to a slightly perturbed problem. We also point out that simplex algorithms with well-behaved updating techniques (such as the Barte...

Administering a glyceryl trinitrate infusion: big is not always best.

With the use of some simple calculations it can be demonstrated that the choice of cannula and initial glyceryl trinitrate (GTN) infusion rate for patients with acute left ventricular failure (LVF) requires some careful thought. If a GTN infusion is commenced at a rate of 1 ml/h, a critically unwell patient with a large cannula--for example, a grey cannula--will have to wait over 6 min for the ...

The effect of bottom-up and top-down auditory program training on the development of children's auditory processing skills

Although there have been several previous investigations on the role of auditory training for the development of auditory processing skills, it still remains unknown whether children with auditory processing difficulties can get improved auditory skills after exposure to a multi-modal training experience comprising both visual and tactile stimuli. The present study, therefore, attempted to use ...
