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...

to survive in today’s competitive environment, companies need continues improvement to achieve goals such as increasing the accuracy of targeting, improving product or service. however, there is no improvement guaranty without performance evaluation. an organization must assess current performance before embarking on any improvement. if it does not, it will have no baseline from which to determ...

In the matrix product states approach to n species diffusion processes the stationary probability distribution is expressed as a matrix product state with respect to a quadratic algebra determined by the dynamics of the process. The quadratic algebra defines a noncommutative space with a SUq(n) quantum group action as its symmetry. Boundary processes amount to the appearance of parameter depend...

Collaborative product development has become a critical issue for companies to strengthen their core competence and remain competitive in the global market due to the rapid change of global economics. However, most companies have a lack of experience in conducting collaborative design and implementing IT environment that facilitates it. To overcome these deficiencies, this research studies coll...
