This paper is concerned with the coordination of inventory control in divergent multiechelon inventory systems under periodic review and decentralized control. All the installations track echelon inventories. Under decentralized control the installations will decide upon replenishment policies that minimize their individual inventory costs. In general these policies do not coincide with the opt...

This paper conducted an economic analysis of the viability of five solar photovoltaic installations in County Tipperary, Ireland. Economic barriers along with policy recommendations are also discussed in detail in order to incentivise solar photovoltaics installations in Ireland. Using costings, solar photovoltaic energy output data and solar radiation data it is also investigated how Irish fin...

A number of semi-permanent light art installations and sculptures was commissioned from different artists, each highlighting a different historical building or one of the many canal-bridges in the city. The installations will all remain in place for a minimum of 10 years. The light art installations together constitute a walking route through the city center under the name “Trajectum Lumen”. Th...

A vision shAred by mAny experts is thAt future communities (residential and commercial developments, university and industrial campuses, military installations, and so on) will be self-sufficient with respect to energy production and will adopt microgrids. With power generation capacities of 10–50 mW, microgrids are usually intended for the local production of power with islanding capabilities ...

The complexity in design and dimensioning of electric traction fixed installations necessitates the development of a methodology for dimensioning based on numerical simulation models. This solution gives faster and more reliable results than those obtained by the empirical and inaccurate methods previously used. A computer aided design tool implementing this methodology is presented in this pap...

This is an overview of the three installations Hoppsa Universum, CLOSE and Flying Carpet. They were all designed as choreographed sound and music installations controlled by the visitors movements. The perspective is from an artistic goal/vision intention in combination with the technical challenges and possibilities. All three installations were realized with video cameras in the ceiling regis...

We address the issue of enabling text entry for walk-up-and-use interactive tabletop displays located in public spaces. Public tabletop installations are characterized by a diverse target user group, multiperson interaction, and the need for high approachability and intuitiveness. We first define the design constraints of text-entry methods for public tabletop installations such as clear afford...

Solar photovoltaic (PV) arrays are providing an increasing fraction of global electrical demand, with an accelerating rate of new installations. Most of these employ conventional glass-fronted panels, but this type of PV array does not satisfy applications that require a light-weight, flexible PV generator. An option discussed in this article is to consider textiles for such solar cell substrat...

Staging is the creative act of showing something to an audience. When staging, the artist chooses and creates the context, situation and structure of the presented object, play or installation. The chosen context and situation provide background for the audience interpretations. Meaning is co-created between the artist and audience, based on the cultural and individual understanding of the cont...
