The induction of demand by increasing the efficiency of a production or consumption process is known as the rebound effect. Feedback loops in System Dynamics can be used to conceptualize the structure of this complex phenomenon and also for communicating model-based insights. In passenger transport, the rebound effect can be induced through increased cost efficiency (direct economic rebound) an...

New information and computing technologies offer cost efficient and effective learning opportunities for health care professionals. The Assisted Electronic Communication project is prototyping, administering and evaluating a digital discourse system for health care professionals within an acute Hospital. Health care staff participating in the study are able to access and contribute to threaded,...

45 eregulation of the energy market is bringing about a fundamental change in the way power equipment assets have to be operated, maintained and replaced. High power-equipment performance is key to cost-efficient energy trading and to the success of the efforts being made by utilities to satisfy end-user demand for high power quality . Three main trends are shaping power equipment life manageme...

Routing is one of the basic parts of a message passing multiprocessor system. The routing procedure has a great impact on the efficiency of a system. Neural algorithms that are currently in use for computer networks require a large number of neurons. If a specific topology of a multiprocessor network is considered, the number of neurons can be reduced. In this paper a new recurrent neural ne...

The aim of this study is to present a new method to predict project time and cost under uncertainty. Assuming that what happens in projects implementation which is expressed in the form of Earned Value Management (EVM) indicators is primarily related to the nature of randomness or unreliability, in this study, by using Monte Carlo simulation, and assuming a specific distribution for the time an...

Machining processes such as end milling are the main steps of production which have major effect on the quality and cost of products. Surface roughness is one of the considerable factors that production managers tend to implement in their decisions. In this study, an artificial neural network is proposed to minimize the surface roughness by tuning the conditions of machining process such as cut...

Airline rescheduling is a relatively new field in airline Operations Research but increasing amounts of traffic will make disturbances to the original schedule more frequent and more severe. Thus, the need to address the various problems arising from this situation with systematic, cost-efficient approaches is becoming more urgent. One such problem is crew rescheduling where after a disturbance...

WDM based dynamic bandwidth allocation schemes are proposed as potential future-proof upgrade solutions for access PON systems. The schemes represent cost-efficient ways to exploit the virtually unlimited bandwidth afforded by passive optical architectures whilst remaining fully compatible with the IEEE Ethernet standard for the first mile (EFM 802.3ah).

Providing carrier grade services to a large number of mobile users is becoming an important challenge for wireless network operators. One promising solution for offering cost-efficient alternatives compared to classical cellular approaches is the use of wireless mesh networks along with the use of heterogeneous radio technologies. In this paper we propose a MAC abstraction layer to lessen the m...

We consider the spread of epidemics in technological and social networks. How do people react? Does awareness and cautious behavior help? We analyze these questions and present a dynamic model to describe the movement of individuals and/or their mobile devices in a certain (idealistic) urban environment. Furthermore, our model incorporates the fact that different locations can accommodate a dif...
