The Selective Laser Sintering Process of thermoplastics (SLS) enables the manufacturing of components with complex shape in a short time period without the manufacturing of a specific mold. However, this manufacturing process is limited by the restricted range of materials. In contrast to this primary shaping process, vacuum casting allows a quick, inexpensive and highly accurate process but it...

The input to the freeform fabrication process is essentially geometric data, raw material, material data and process parameters. Optimal process parameters depend upon current material and the part geometry. This paper describes an research approach in which all necessary input including process parameters are obtained or derived from the product model. The part geometry with its process parame...

It has been known since Rhodes Fairbridge’s first attempt to establish a global pattern of Holocene sealevel change by combining evidence from Western Australia and from sites in the northern hemisphere that the details of sea-level history since the Last Glacial Maximum vary considerably across the globe. The Australian region is relatively stable tectonically and is situated in the ‘far-field...

Detection of faults is a continuing need in all manufacturing processes. This need is more pronounced in new manufacturing processes where continual product improvement is desired. In this paper, a systematic approach is developed for addressing this need. Contemporary experimental and surface analysis techniques provide a basis for incrementally diagnosing the fault mechanisms leading to surfa...

Sexual exploitation and abuse (SEA) is an endemic problem in UN peacekeeping missions. It is not only a gross human rights violation, but also threatens to challenge the legitimacy of the peacekeeping mission, poses a health problem, and undermines the promotion of gender equality in host countries. We examine if the composition of peacekeeping forces along two dimensions—the proportion of wome...

The SIS community has made progress recently toward evaluating SLS systems that deal with dialogue, but there is still considerable work that needs to be done in this area. Our goal is to develop incremental ways to evaluate dialogue processing, not just going from Class D1 (dialogue pairs) to Class D2 (dialogue triples), but measuring aspects of dialogue processing other than length. We presen...

Spoken language systems (SLSs) for accessing information sources or services through the telephone network and the Internet are currently being trialed and deployed for a variety of tasks. Evaluating the usability of different interface designs requires a method for comparing performance of different versions of the SLS. Recently, Walker et al (1997) proposed PARADISE (PARAdigm for DIalogue Sys...

The Scientific Leadership Scholars (SLS) Program is an NSF S-STEM sponsored scholarship for financially and academically eligible students in Computer Science, Environmental Resources Engineering and Mathematics at Humboldt State University. The scholarship has sponsored 57 students in these majors over the past 4 years. Of these students, 54% were underrepresented minorities and 70% were under...

[1] Over the past decade, efforts to estimate temperature and sea level for the past 50 Ma have increased. In parallel, efforts to model ice sheet changes during this period have been ongoing. We review published paleodata and modeling work to provide insights into how sea level responds to changing temperature through changes in ice volume and thermal expansion. To date, the temperature to sea...
