The temperaturerepresents the silicon chip, packages and dependent IGBT electrical model describes the instantaneous electrical behavior in The characteristics of the IGBT silicon are vastly terms of the instantaneous temperature of Segment C chip surface. The instantaneous power dissipated in the IGBT is calculated usingand B (which different than those of Segments A the electrical model and determines the instantaneous heat rate that is applied to the surface of the silicon are located on the subject property) chip thermal model. Hefner incorporated this methodology into the SABER circuit simulator. The characteristics of the dominant portion of the • Adams, Joshi and(Segment C) are suggestive of a perennial system Blackburn considered thermal interactions between the heat sources, substrate, and encloses walls as affected by the thermal conductance of the stream walls and substrate with the intent of determining which physical effects and level of detail are necessary to accurately predict thermal behavior of discretely heated Direct observations are needed enclosures. • A detailed technical analysis and electrical by a Chen, Wu and Borojevich are modeling of thermalis needed behavior using several qualified, independent hydrologist.

Iron ores make up 5.6% of the earth ’s crust Where is the largest concentration of iron ores and account for 95% in North America? of the metals used Iron Ore Distribution Iron • An abundant metal, makes up 5.6% of earth’s crust • Properties: – shaped, sharpened, welded – strong, durable Iron Ore Distribution Iron ore • Accounts for >95% of metals used • Iron ores discovered in 1844 in Michigan’s Upper Peninsula • Soon found other ores in upper Wisconsin and Minnesota [www.star -bits.com ] Is strong and durable Can be shaped, sharpened, and welded [Kesler 1994] Kesler 1994 Led to 59% recall Led to 77% recall Level of significance < 0.001 [Alley et al., 2006] When the tested assertion was in the sentence headline, students performed significantly better 3.5 Score (Sentence) / Score (Traditional) 3.0 Statistically significant increase No significant difference Statistically significant decrease 2.5 2.0 1.5 1.0 0.5 0.0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Question Overall percent correct (traditional headline): Overall percent correct (sentence headline): 70% 82% p < 0.001 [Alley et al., 2006] Recent research at TAMK shows the sentence headline helps students understand information “The sentence headline, and the information it contained, helped me to understand the meaning of the slide.” 80 % 70 % 60 % 50 % 40 % 30 % 20 % 10 % 0% Strongly agree Slightly agree In total, 54 students answered the questionnaire In summary, this slide design is much more effective than PowerPoint’s default design The water cutting system consists of six major parts Nozzle Highpressure water line Abrasive container more readily understood more memorable Hydraulic pump High pressure pump Tap water in more persuasive [Sulkala & Vierula, 2006] Questions?
