It is obvious that the set of product functional features has a major role in the purchase decision. However, for a same product, users may have different assessments. So it seems that other factors than product functional characteristics play a role in decision making. Frequently, customers are segmented based on characteristics such as age, gender, geographic location, etc. Nevertheless, in many cases it has been seen that the customers in the same segment have different points-of-view for the same product. For example, some customers in a group may consider a product suitable while others don't. Inconsistencies between customers can cause uncertainty for designers in producing the most satisfying product attributes. This paper presents a method to resolve this kind of uncertainty using Rough Set Theory. The input of this method is users' evaluation data for a product with respect to a specific customer subjective feeling. The output is sets of the most influential users' characteristics on their product selection preferences. By using reduced sets of users' characteristics, designers are able to reclassify users and resolve inconsistencies. <br>description: Paper presented to the 5th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, May 1, 2009. <br> Thu, 30 Apr 2009 22:58:59 GMT http://hdl.handle.net/10057/2328 title: Speech-language pathologists' self-assessment of knowledge regarding medications to treat behaviors associated with autism spectrum disorder. authors: Daiquirie Crumrine; Self, Trisha; LaDonna S. Hale <br>abstract: Children with Autism Spectrum Disorder (ASD) are often prescribed medications to help control self-injurious behaviors, aggression, compulsive behaviors, and hyperactivity. Speech-Language Pathologists (SLPs) should be familiar with medication-related behavior changes and side effects. The purpose of this study was to evaluate SLPs' self-assessment of knowledge regarding medications prescribed to children with ASD. SLPs registered with the Kansas Speech- Language Hearing Association were provided a link to an online survey. The response rate was 13%, (n = 56). Overall, 88% of respondents felt they had a good understanding of ASD characteristics; but only 15% felt they had a good understanding of ASD medications. Only 14% were satisfied with their medication knowledge, 79% wanted to be more knowledgeable, and 60% felt they knew where to locate medication information. SLPs that completed continuing education were more likely to be satisfied with their knowledge regarding ASD characteristics than with ASD medications. <br>description: Paper presented to the 5th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, May 1, 2009. <br> Thu, 30 Apr 2009 22:58:59 GMT http://hdl.handle.net/10057/2327 title: Statistical presentation of the flight environment of the propellers on commuter aircraft. authors: Dorfling, Johann; Kliment, Linda K.; Rokhsaz, Kamran <br>abstract: Data obtained from digital flight data recorders installed on a fleet of 27 Beech 1900D airliners are used to assess the actual operational environment of propellers on commuter aircraft. The data consists of 910 complete flights and 589 flight hours. The short duration takeoff rotation is identified as the most severe phase of operation with regard to vibratory loads on the propeller blades resulting from a tilted inflow angle. Also, normal accelerations data, which reflect the turbulence experienced in flight, is converted to the resulting change in the propeller inflow angle. Increasing altitude shows a significant reduction in the frequency and magnitude of the inflow angle variation caused by gusts. The information is presented in statistical formats that could enable the FAA, manufacturers and operators to better understand and control those factors that influence the structural integrity of these components <br>description: Paper presented to the 5th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, May 1, 2009. <br> Thu, 30 Apr 2009 22:58:59 GMT http://hdl.handle.net/10057/2325 title: Crack arrest capabilities in adhesively bonded skin and stiffener authors: Habeeb, Shamsuzuha; Raju, K.S. <br>abstract: The crack arrest capabilities and the load bearing characteristic of a stiffened and unstiffened panel subjected to uniform remote displacement field is examined in this paper. A four stringer stiffened wide panel is analyzed for a center crack, propagating towards the adjacent stringers. The linear elastic analyses indicated a decrease in stress intensity factor when the crack approaches the stiffener. The non-linear analysis with crack across the skin-stringer assembly indicated a reduction in strength relative to an unstiffened panel. <br>description: Paper presented to the 5th Annual Symposium on Graduate Research and Scholarly Projects (GRASP) held at the Hughes Metropolitan Complex, Wichita State University, May 1, 2009. <br> Thu, 30 Apr 2009 22:58:59 GMT
