In gauge theories like the standard model, the electric charges of the fermions can be heavily constrained from the classical structure of the theory and from the cancellation of anomalies. We argue that the anomaly conditions are not quite as well motivated as the classical constraints, since it is possible that new fermions could exist which cancel potential anomalies. For this reason we exam...

18 ANSYS ADVANTAGE ISSUE 2 | 2017 Leading the Electric Vehicle Charge The battery management system plays a critical role in today’s electric vehicles: It monitors the state of the battery, manages its operation to optimize vehicle performance and battery life, and ensures the safety of occupants. Researchers at National Electric Vehicles Sweden (NEVS) who are developing the BMS for their next-...

By treating magnetic charge as a gauge symmetry through the introduction of a " magnetic " pseudo four-vector potential, it is shown that it is possible, using the 't Hooft-Polyakov construction, to obtain a topological electric charge. The mass of this electrically charged particle is found to be on the order of 1 137 M W as opposed to the much larger mass (on the order of 137M W) of the magne...

We calculate the cosmic microwave background (CMB) anisotropy spectrum in models with millicharged particles of electric charge q ∼ 10−6 − 10−1 in units of electron charge. We find that a large region of the parameter space for the millicharged particles exists where their effect on the CMB spectrum is similar to the effect of baryons. Using WMAP data on the CMB anisotropy and assuming Big Bang...

Title of Thesis: LONGITUDINAL EFFECTS AND FOCUSING IN SPACE-CHARGE DOMINATED BEAMS Degree candidate: John Richardson Harris Degree and year: Master of Science, 2002 Thesis directed by: Professor Patrick G. O'Shea Department of Electrical and Computer Engineering The purpose of this thesis is to investigate longitudinal effects in space-charge dominated beams, and to begin design of a longitudin...

Space charge lenses use a confined electron cloud for the focusing of ion beams. Due to the electric space charge field, the focusing is independent of the particle mass. For this reason the application of space charge lenses especially in the field of heavy ion beams is advantageous. Moreover, the trapped non neutral plasma cloud compensates the space charge forces of the ion beam. The focusin...

It is important to reveal the relations of physical factors to deposition of contaminants on insulator. In this paper, the simulation model of high voltage end of insulator was established to study the force and motion characteristics of particles affected by electric force and airflow drag force near the ultra-high voltage direct current (UHVDC) insulator. By finite element method, the electri...

A basic background is given of the concepts and measurements of dielectric phenomena, and two examples of dielectric-based biosensors are described. The way in which the dielectric properties of immobilized urease can be used to monitor the hydrolysis of urea is first outlined, while the second example describes how the phenomenon of dielectrophoresis can be used to monitor the concentration an...

In this paper we analyze the perturbations of the Kerr-Newman dilatonic black hole background. For this purpose we perfom a double expansion in both the background electric charge and the wave parameters of the relevant quantities in the Newman-Penrose formalism. We then display the gravita-tional, dilatonic and electromagnetic equations, which reproduce the static solution (at zero order in th...
