We study the physics of spontaneously broken family symmetries acting on the third generation. Massless familons φ associated with such broken symmetries are motivated especially by cosmological scenarios with decaying tau neutrinos. We first note that, in marked contrast with the case for the first two generations, constraints on third generation familon couplings are poor, and are, in fact, n...

Using the preliminary data on Bd-Bd mixing from ARGUS, and the standard model with three families, we infer a lower bound on the top quark mass of 50-70 GeV; also, Bs-B~ mixing has to be close to maximal. We discuss how the prospects for observing CP violation in B ° decays are enhanced and sketch alternative scenarios for new physics. 1. Introduction Almost from the inception orB physics it wa...

This report shows how to realize a gesture recognition system for controlling appliances in home environments. It gives a brief overview on an existing system and clariies details on ergonomic remote control of devices by gestures with the help of a vision system. The focus is on the motion detection, object normalization and identiication, the modelling and the prediction of motion by the Kalm...

In this paper we describe and analyze The Argus Project, a sound installation involving the real-time processing and spatialized projection of sound sources from beneath a pond’s surface. The primary aim of The Argus Project is to project the natural sound sources from below the pond’s surface while tracking the changes in the environmental factors above the surface so as to map this data onto ...

The occurrence of a coccidian parasite, Cryptosporidium, among birds in the Kuala Lumpur National Zoo was investigated in this study. A hundred bird fecal samples were taken from various locations of the zoo. Fecal smears prepared using direct smear and formalin ethyl acetate concentration technique were stained with modified Ziehl-Neelsen stain. Samples positive for Cryptosporidium with Ziehl-...

This paper motivates and describes the thesis work that will be done as part of the author's Master of Engineering degree requirements. We present the primary thesis of the work: it is desirable, feasible, and practical to build a device for rapidly acquiring dense pose image datasets. Pose images are digital images tagged with estimates of the camera's 6 degreeof-freedom (DOF) position and ori...
