Hardness Tests on Damaged Metals
1999The development of cracks inside the material is usually investigated on the entire production by means of non destructive inspection techniques. Unfortunately, the progress of ductile damage cannot be observed with these techniques because of the small dimensions of the single cavity.

Hardness Methods for Testing Maize Kernels
Journal of Agricultural and Food Chemistry, 2009Maize is a highly important crop to many countries around the world, through the sale of the maize crop to domestic processors and subsequent production of maize products and also provides a staple food to subsistance farms in undeveloped countries. In many countries, there have been long-term research efforts to develop a suitable hardness method that

Hardness Testing: Principles and Applications is an in-depth study of one of the most fundamental properties of materials and the tools and techniques that have been developed to measure it. Hardness, as defined in the first chapter, is a type of resistance to deformation, the roots of which lie in the packing density of atoms and the bonding forces ...

Archives of Neurology, 1994
We commend DePippo and colleagues 1 for studying the 3-oz water swallow test, a simple but potentially useful bedside test for aspiration after stroke. Before being of use to clinicians, however, it is essential to provide more details about the test procedures such as the patient's position (upright position was recommended in the "Comments" section ...

IEEE Security & Privacy, 2003
Software testing fairly readily detects a program's failure to do what it is designed to do, but does not detect all of the other things that it may do in the process. Some of these may compromise security. The article discusses the development of methods and software tools to deal with these bugs.

Hardness Testing of Vulcanized Rubber. VIII. Hardness Tests with a Conical Indentor
Rubber Chemistry and Technology, 1948Abstract The relation between load and depth of indentation for a conical indentor has been investigated. The theoretical relationship applicable to perfectly elastic materials (indentation proportional to square root of load) is found to hold for all the rubbers examined except one very hard sample, whose comparative inelasticity causes some ...
