Demand estimation is important for new-product strategies, but is challenging in the absence of actual sales data. We develop a cost-effective method to estimate the demand of new products based on choice experiments. Our premise is that there exists a structural relationship between manifested demand and the probability of consumer choice being realized. We illustrate the mechanism using a the...

We present simulations of a model for the formation of a prominence condensation in a coronal loop. The key idea behind the model is that the spatial localization of loop heating near the chromosphere leads to a catastrophic cooling in the corona (Antiochos & Klimchuk 1991). Using a new adaptive grid code, we simulate the complete growth of a condensation, and find that after ∼ 5, 000 s it reac...

Discourse markers ('cue words') are lexical items that signal the kind of coherence relation holding between adjacent text spans; for example, because, since, and for this reason are different markers for causal relations. Discourse markers are a syntactically quite heterogeneous group of words, many of which are traditionally treated as function words belonging to the realm of grammar rather t...

Voice over Internet Protocol (VoIP) is a rapidly growing technology that enables transport of voice over data networks such as Ethernet local area networks (LANs). This growth is due to the integration of voice and data traffic over the existing networking infrastructure, low cost, and improved network management offered by the technology. This research investigates the performance of VoIP traf...

After an object-oriented framework for micro-processor based fire alarm systems had been implemented and the first instantiated system had reached product status an effort was undertaken to clearly document the architecture embedded in the framework. The result of this effort was a small pattern language which is presented in this paper. Important patterns in this language are the Point pattern...

We have recently developed the capability to make solar vector (Stokes IQUV) magnetograms using the infrared line of MgI at 12.32 μm. On 24 April 2001, we obtained a vector magnetic map of solar active region NOAA 9433, fortuitously just prior to the occurrence of an M2 flare. Examination of a sequence of SOHO/MDI magnetograms, and comparison with ground-based H-alpha images, shows that the fla...

Sunspots in NOAA active region 7978 rst appeared on July 6, 1996, while the region was at E15. The spots reached an area of 400 millionths within four days and the active complex remained interesting for at least ve solar rotations, generating an X class are, a long-duration event, and coronal mass ejections well-observed by both Yohkoh and SOHO. During these ve rotations, only a few short-live...

This is a descriptive, quantitative, and hypotheses testing study conducted on entrepreneurial and professional CEOs. This study has a particular interest in small medium enterprises (SMEs) because it constitutes the core of our economy and is a major factor of social composition. The purpose of present study is to investigate and explore differences on the motivational profile of Pakistani ent...

Working with ‘real-world’ problems is at the centre of the RAMESES research project which focuses on Small Medium Enterprises (SMEs). In designing the study care had to be taken to ensure the relevance of the research techniques to be used.. This paper outlines the benefits of using a combination of qualitative and quantitative research methods within the bounds of a multi-disciplinary research...

Software Maintenance (SM) constitutes a critical function that enables organizations to continually leverage their IT capabilities. However a majority of the SM methodologies are geared toward large organizations. This is detrimental to small organizations (SO), for which SM remains an important function. This research contributes to the discipline by a) evaluating the appropriateness of existi...
