Micro mechanical components play an increasing role in micro systems with product dimensions ranging from micrometers to millimetres. The use of metals, polymers and ceramics for miniature components requires product development methods as well as specific manufacturing technologies. Indeed it is now well known that micro/nanotechnology is not only a matter of downscaling applications and metho...

While the business models used in most segments of the media industry have been profoundly changed by the Internet surprisingly little has changed in the publishing of scholarly peer reviewed journals. Electronic delivery has become the norm, but the same publishers as before are still dominating the market, selling content to subscribers. This article asks the question why Open Access (OA) to ...

A new application for VR has emerged: product development, in which several stakeholders (from engineers to end users) use the same VR for development and communicate purposes. Various characteristics among these stakeholders vary considerably, which imposes potential constraints to the VR. The current paper discusses the influence of three types of exploration of objects (i.e., none, passive, ...

Note that a phrase headed by -te (teP) is usually an adjunct floating around in a sentence (like English gerunds); however, when V-te is adjacent to a verb from a certain set of verbs, they jointly form a single complex predicate. The status of a [V-te V] string as a complex predicate (rather than two separate predicates) is clear when the semantics of V2 is significantly lightened, but even if...

We introduce the circle product, a method to construct simple graphs starting from known ones. The circle product can be applied in many different situations and when applied to regular graphs and to their decompositions, a new regular graph is obtained together with a new decomposition. In this paper we show how it can be used to construct infinitely many new solutions to the Oberwolfach probl...

Collaborating with a supplier in a buying firm’s new product development (NPD) project is commonly advocated and adopted, but does not always improve project performance. Some pre-existing collaboration contexts, such as buyer-supplier NPD projects, are especially exposed to supplier opportunism due to the uncertain nature of the collaboration process. Adopting agency theory and transaction cos...

Cooperative product development projects in the aerospace and defense industry are held hostage to high cost and risk due to poor alignment of collaborative design tools and processes. This impasse can be broken if companies will jointly develop implementation approaches and practices in support of high value working arrangements. The current tools can be used to better advantage in many situat...

A new and efficient method has been developed for the synthesis of 4-aryl-7-benzylidene-1,3,4,5,6,7-hexahydro-2H-cyclopenta[d]pyrimidin-2-ones through Biginelli-like reaction of cyclopentanone, with urea/thiourea and aromatic aldehyde employing p-dodecylbenzenesulfonic acid (DBSA) as a recyclable catalyst under solvent-free condition. The recovered catalyst was recycled for further runs. The pr...

abstract regarding temporal variation of rivers discharge and demands, for suitable use of dam reservoirs stored water, application of operation rule curves is necessary. operation rules are expressed with rule curves. application of yield model is one of the methods of operation curve preparation, which correlates reservoir operation with reservoir storage volume in first period. in this study...
