Title: Does Non-Compliance with Route/Destination Assignment Compromise Evacuation Efficiency?

Abstract

This paper documents studies of two real-world network evacuation cases, each with a different, but proven, simulation software package. The purpose of these studies was to examine whether the rate of evacuees' compliance with predetermined route/destination assignments would have an impact on the efficiency of evacuation operations. Results from both cases suggest that a rate of less than 100% compliance does not compromise evacuation efficiency. In fact, although this is counter-intuitive, evacuation efficiency would actually improve as a result of "sensible" non-compliance on the part of the evacuees. A closer observation of the results revealed that the somewhat unexpected improvement results from a reduction in congestion along designated evacuation routes as evacuees spread out to less prominent parallel streets and other non-congested outbound routes. This suggests that by being limited by the zone-to-zone and one-to-one assignment framework, conventional evacuation plans may have fallen short of providing the most efficient guidance to evacuees. To address this issue, some systematic means, perhaps simulation-based, should be performed to assess the zone partitions, route designations, and destination assignments in existing evacuation plans. Thus, evacuation planning with route/destination assignments based on origin zones may be flawed and may deserve reconsideration. After all, once en route,more » where an evacuee is coming from is of far less consequence than where he or she is going.« less

  • The authors use an iterative re-planning scheme with simulation feedback to generate a self-consistent route-set for a given street network and origin-destination matrix. The iteration process is defined by three parameters. They found that they have influence on the speed of the relaxation, but not necessarily on its final state.
  • Nowadays a lot of different femtosecond lasers and femtosecond laser systems have found their places in many chemical, biological and physics laboratories. Natural desire of every investigator is to have laser radiation in spectral range that is as wide as possible. Really, one of the best and convenient ways to expand the spectral range of existing femtosecond lasers is frequency conversion of laser radiation in nonlinear crystals. Here, the phenomenon of phase-matching curve transformation under strong energy exchange conditions and its influence on frequency conversion of ultrashort light pulses in nonlinear crystals are discussed. The routes to increase energy conversionmore » efficiency in three-wave interactions are suggested.« less
  • The principles of site energy efficiency measurement are briefly discussed and a summary of the efficiency of 35 major industrial sites, which have been surveyed, are presented. A case study of a site which incorporates a conversion refinery, a steam cracker and an aromatics complex is presented showing the site efficiency of the current operation, the systematic approach used to evaluate energy reduction opportunities and the achievable efficiency after implementation of economically justifiable investment opportunities.

  • Spray drying imparts unique powder handling features to a wide variety of dried products and is usually carried out in a heated air stream while feeding an aqueous suspension of some solid material. The present work, however, describes non-aqueous spray drying as a means of preparing fine powders of metal oxides. In this case an alcohol solvent was used in place of water and the slurry sprayed under an inert atmosphere. Using the non-aqueous technique, the product consists of distinct but loosely aggregated primary particles. Such materials have potential for use as catalysts or catalyst supports.
