Test and Tester Qualifications, Part 1: Introduction

Statistics for dental researchers; part 1: Introduction

Learning statistics is a necessity for dental researchers. Due to daily dental science expansion, dental researchers have to study new papers in recent dental journals to remain up to date. On the other hand, knowing principles of statistics helps better understanding of the articles. Some authors revealed that knowledge of dentists about basic topics of statistics was poor. Therefore, in this ...

An Introduction to Scan Test for Test Engineers Part 1 of 2

For any modern chip design with a considerably large portion of logic, design for test (DFT) and in particular implementing scan test are mandatory parts of the design process that helps to reduce the complexity of testing sequential circuits. The basic concept of a scan test is to connect memory elements like flipflops or latches forming chains, so that shifting through scan chains allows to c...

Constant rank constraint qualifications: a geometric introduction

Constraint qualifications (CQ) are assumptions on the algebraic description of the feasible set of an optimization problem that ensure that the KKT conditions hold at any local minimum. In this work we show that constraint qualifications based on the notion of constant rank can be understood as assumptions that ensure that the polar of the linear approximation of the tangent cone, generated by ...

Introduction to the aging brain, Part 1.

on noveMber 9, 2011, a cMe course was held In provIdence on the Aging Brain. The papers in this and another issue to follow contain summaries of the talks given. All physicians, excepting pediatricians deal with elderly patients, and are doing so at increasing rates. In addition, of course, we are all aging ourselves. As Houston Merritt, MD, one of the great neurologists of the twentieth centur...
