Our results compared with those in previous experiments [11] indicate that Flowmenu offers as much of an advantage over tool palette selection as does Toolglass [2], a twohanded technique. At the same time, it is not significantly slower than marking menus. Additional results show that selection performance depends on distance around the menu, but not on initial position or direction. These res...

AIM To compare an ultrasonic height measuring device (Gulliver) with mechanical stadiometry and the classical "book and tape measure" method. METHODS Blinded duplicate measurements of height were made on each of 14 children by a pair of observers using a stadiometer (H) and Gulliver (G). Height was measured on a further 18 children by parents and an auxologist using Gulliver and the book and ...

This instantly raises a question: what do we mean by performance? Most of us have an informal sense of what we mean. Perhaps we mean we don’t want to wait for our commands to complete. Perhaps we mean we want to run complex calculations on very large data sets fast enough for the results to be useful. Perhaps we mean we want to get the most possible work through a given piece of hardware that w...

In this paper we evaluate the performance of scene detection techniques, starting from the classic precision/recall approach, moving to the better designed coverage/overflow measures, and finally proposing an improved metric, in order to solve frequently observed cases in which the numeric interpretation is different from the expected results. Numerical evaluation is performed on two recent pro...

In the last years performance evaluation issues have attracted the attention of many researchers and companies worldwide. However, most studies are still conducted focusing only on the manufacturing processes performance and associated with financial indicators. Currently an important question is the necessity of expanding the concepts of performance evaluation to the supply chains, in order to...

HSDPA is making impressive inroads in the commercial service arena. On September 22, 2006, the Global mobile Suppliers Association (GSA) reported that 121 HSDPA networks had been planned, were being deployed, or had been launched. Moreover, 59 of these already offered commercial HSDPA services. Likewise, 58 HSDPA devices had been launched as of September 18, 2006. Numerous operators thus do alr...

This is a theoretical paper that has the purpose of reviewing previous experiences based on surveying the extant literature with the aim of delving into the subject of Knowledge Management (KM) Performance. It is an attempt to try to identify performance indicators for measuring KM systems. The paper presents important works related to direct KM performance and another way of evaluating KM perf...
