This paper presents the optimal modeling of Power Law Filters (PLFs) with low-pass (LP), high-pass (HP), band-pass (BP), and band-stop (BS) responses by means rational approximants. The optimization is performed for three different objective functions second-order filter mother functions. formulated design constraints help avoid placement zeros poles on right-half s-plane, thus, yielding stable...

The Industrial Ecology (IE) is a new interdisciplinary field focused on sustainable development. IE aims to the shifting of industrial processes from open-loop systems where different resources move through a system to become wastes to a closed-loop system where wastes become inputs for new processes. This paper introduces a Green Virtual Enterprise (GVE) model as an emerging sustainable manufa...

Todays, sustainable development is one of the principles which are considered by scholars. This means that the future of humanity is very important to maintain living standards, so that it can no longer operate as before and use the human environment. Therefore the effects of tourism should be studied perfectly to minimize its threat and maximize opportunities and strength points and this wou...

In the first part we provide a review of the rather young field of Environmental Informatics. We argue that Environmental Informatics methods and tools are powerful means in environmental information processing for supporting sustainable development. In the second part we introduce a case study dealing with sustainable logistic systems for city courier services based on agent-based simulation m...

Resource depletion and e-waste generation through electronics use have reached an alarming stage in developing countries, posing a serious threat to the environment and human health (Wath, Dutt & Chakrabarti 2011:260). During the last decade, there has been an exponential increase in the use of electronics in India, and most of these are discarded irresponsibly by consumers (Wath et al. 2011:25...

This chapter focuses on an auction-based procurement framework for single coordinating platforms in humanitarian logistics. It first covers disaster relief operations, humanitarian logistics, and procurement in this context and illustrate many of the issues that make the management and coordination of procurement functions complex and challenging. Then the proposed framework along with the auct...

Tracking&Tracing-systems have been used for years in the logistics and food industry for the monitoring, control and management of processes. In general, the usage of systems includes applications such as finding the source of recalls, proof of product quality and origin, improving logistics and production processes. The benefits of these systems in the specific environment of the wood supply c...

In the situation where a large increase in trade and freight transport volumes in the Baltic Sea region (BSR) is expected and in which the BSR is facing a major economic restructuring, efforts to achieve more integrated and sustainable transport and communication links within the BSR are needed. One of these efforts is the development of logistics centres (LCs) and their networking, which will ...

the theoretical calculation of the energies of projectile like fragments (plfs) using the heavy-ion reactions between 76ge and 198pt are reported in this article. the incident beam energy was 635 mev. the calculated values of plfs are compared with the previous experimental results and it is shown that the theoretical calculations of plfs are consistent with the experimental values. the elastic...
