The goal of this thesis work has been to develop and manufacture an ice layer which was to be mounted on the tip of a scaled down wing model. The iced wing should be tested in a wind tunnel and aerodynamic comparisons should be made to the same wing without ice. The development of the ice was carried out as a modified product development process. The main differences are that there is no costum...

In this paper, design data from a protocol analysis experiment is used to validate that EnvironmentBased Design (EBD) is a descriptive model of design. The EBD is developed as a design methodology for innovative and creative design based on the understanding of the generic design process. The validation of EBD is conducted by using it to describe and represent the design data collected from pro...

Graphic representations that show how the design process changes over the course of solving a problem are powerful tools for researchers. This paper presents three such representations—timelines, cumulative time plots, and progress time plots—and describes how they provide insights into the design process of engineers.

Inclusions have been observed in the mitochon~ dria of human liver parenchymal cells in a number of pathological states and have been variously described as "crystalline," "para-crystalline ," "myelin figures," or "myelin degenera-tion" (1-12). It is generally assumed that these structures represent an abnormal change, little emphasis having been placed on their occurrence in normal specimens (...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'What is the value of topical cooling as an adjunct to myocardial protection?' Using the reported search, 9 papers represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outc...

While many computer engineering curric-ula contain signiicant design projects encompassing either hardware or software, most do not integrate these experiences, are short-term in nature, lack exposure to industrial design tools, do not have hands-on experience, or lack continuity. URI's new ICED undergraduate curriculum addresses these issues through a comprehensive multi-year project. The proj...

three hundred and four patients with different degrees of heatstroke were treated by the hajj medical team of the islamic republic of iran. four percent of the patients had associated diseases. a simple method using immersion in iced tap water was used for management of heatstroke. advantages and wide applicability of the technique are described, achieving good results without using sophisticat...
