Energy efficiency model for the mini-load automated storage and retrieval systems

In this paper, the energy efficiency model for the mini-load AS/RS is presented. As the existing models of AS/RS apply to already well-known objectives (minimum travel time, maximum throughput and minimum cost), the energy efficiency model for the mini-load AS/RS is proposed and discussed. According to global trends in material handling and warehousing, the design process should encompass not only the application of the equipment with fastest drives but should also consider the energy and environment aspect on the installed equipment. The proposed energy efficiency model for the mini-load AS/RS enables reduction of energy consumption and consequently the CO₂ emission, which is good from the economic and environmental point of view. We sincerely hope that the energy and environment aspect will indubitably bring changes into planning of warehouses and will mean great challenge for those who are engaged in the planning process.     

Limitations to compacting a parallel‐plate Blumlein pulse‐forming line

For the applications of compact pulsed‐power systems, we propose a model for optimizing the pulse‐forming line (PFL) with respect to the optimum pulse generation. There are multiple parameters that play important and conflicting roles in the design of a PFL. The original notion that a pulse, of a desired duration, can be created and the length of the line shortened by using a dielectric with sufficiently high permittivity, is shown here to be overly simplified, and that it can lead to a deformed pulse instead. In this work, new criteria for successful pulse formation are proposed and their validity demonstrated. © 2008 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2008.
