This paper aims at explaining how intermediaries influence collaborative innovation projects, suggesting a conceptual-theoretical framework about intermediaries’ roles and practices. The qualitative research was developed through the case study of the Orange Service Call and Reward project performed by the National Endowment for Science, Technology and the Arts (NESTA) for Orange Labs, the R&D ...

Electronic Assessment systems usually provide an authoring tool for creating activities (mainly closed-type questions) and administering the flow of their presentation and are also complemented with a delivery environment for learners. In this paper, we discuss learner’s control over authored assessment. The prototype application, ReACTS (Re-Adaptable Computerized Testing System), enables learn...

In this paper, we address the issues of maintaining sensing coverage and connectivity by keeping a minimum number of sensor nodes in the active mode in wireless sensor networks. We investigate the relationship between coverage and connectivity by solving the following two sub-problems. First, we prove that if the radio range is at least twice the sensing range, complete coverage of a convex are...

This article aims to identify how knowledge workers develop their own collaboration strategies and techniques for getting their work done in complex, dynamic knowledge intensive work environments. Three case studies have been conducted to explore the nature of routines in different collaborative working settings as they provide sufficient detail to better understand the actual state and problem...

This paper presents FrameNet’s approach to the representation of Support Verbs, as but one type of multiword expression (MWE) included in the database. In addition to motivating and illustrating FrameNet’s newly consistent annotation practice for Support Verb constructions, the present work advocates adopting a broad view of what constitutes a multiword expression.

Adsorption cold storage has lately attracted attention for its large storage capacity and zero cold energy loss during the storing process. Thermodynamic and experimental studies on the cold storage capacity and the cold discharging process, in which the adsorber is either air cooled or adiabatic, have been presented. An adsorption cold storage system with zeolite–water working pair has been de...

Tepe Sagzabad, a site situated on the Qazvin Plain of north-central Iran, was excavated from 1970 to 1998 by the Institute ofArchaeology of Tehran University. Recent excavations by H. Tala’i (1997-1999) yielded some metal artifacts dating to theEarly Iron Age. Ten of these copper-based samples were investigated using inductively coupled plasma optical emissionspectroscopy (ICP-OES), scanning el...

A particularly simple Markov chain model for a reference string is described. The model, which is only slightly more complicated than the independent reference model, generates strings that have a locality property and that have a specified probability distribution of references over pages. Expressions are obtained for expected working-set size and expected working-set miss ratio. The of change...
