Fermilab has just completed a very successful 1992-1996 Collider Run I which has led to the discovery of the top quark [1, 2] along with many other remarkable physics results. A typical luminosity of 2×10 cm s was achieved with 7×10 antiprotons in each of 6 bunches. The total integrated luminosity delivered to both the CDF and DØ collider detectors was about 150pb (see Fig. 1). The collider rel...

This paper reports a phenomenographic investigation into students’ experiences of learning through discussion – both online and face to face (F2F). The study context was a second-year undergraduate course in psychology for social work in which the teacher had designed discussion tasks to begin in F2F mode and to continue online. A combination of open-ended questionnaires and semi-structured int...

The OPERA experiment is designed to study the nm ! nt oscillation observing the nt appearance in a pure nm beam over a base line of 732 km from CERN to Gran Sasso Laboratory. The apparatus consists of a lead/emulsion-film target complemented by electronic detectors and muon spectrometers for muon charge and momentum measurements. The tracking inside the magnets is provide by Bakelite RPC chambe...

This paper deals with the real time simulation of a class A single ended guitar power amplifier. Power tubes and triode models are compared, based on Norman Koren’s work. Beam tetrodes and pentodes characteristics are discussed, and displayed as Norman Koren’s model parameters. A simple output transformer model is considered, with its parameters calculated from datasheets specifications. Then, ...

This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...
