TL;DR: In this paper, the authors studied continuous and discontinuous pulse-width modulation for the three-level neutral-point-clamped voltage source inverter in high power, medium voltage applications and showed that the average switching frequency is not directly proportional to the carrier or sampling frequency.
Abstract: The three-level neutral-point-clamped voltage source inverter is widely used in high power, medium voltage applications. This paper studies continuous and discontinuous pulse-width modulation for this inverter. Detailed analysis of discontinuous modulation shows that the average switching frequency is not directly proportional to the carrier or sampling frequency, since additional switching transitions occur between different regions of discontinuity. At typical switching frequencies for high power applications (up to 2 kHz) these additional transitions contribute significantly to the inverter's total losses, so that a proper comparison of the harmonic performance can only be carried out under constant loss conditions with varying carrier frequency. This comparison is performed for a typical industrial medium voltage inverter. The paper then considers the major issues of neutral-point voltage balancing and loss distribution within the inverter, for the identified optimal modulation schemes.

TL;DR: Improved thermal technologies, such as ohmic heating, which allows direct heating of the product and overcoming the heat transfer limitations of conventional thermal processing are presented in terms of their applicability to reduce the thermal exposure during food preservation and non-thermal technologies such as high hydrostatic pressure and pulsed electric fields and their ability to extend the shelf life of food products without the application of heat are discussed.

TL;DR: An overview of the emerging field of intelligent agents (IAs) by identifying their basic properties and looking at their potential impacts on open service architectures, intelligent communications and network management.
Abstract: The telecommunications environment is changing its face towards an open market of information services where the vision is "information any time, at any place, in any form". Within this electronic market the aspects of service customization and instant service provision are of fundamental importance. In this context a new paradigm is gaining momentum referred to as "intelligent agents". This paper provides an overview of the emerging field of intelligent agents (IAs) by identifying their basic properties. Focusing on mobile agents, which could be considered as a specific class of intelligent agents, we identify the chances of agent technology in the context of telecommunications. We look at their potential impacts on open service architectures, intelligent communications and network management.
