reacting with products formed during thehydration of cement. Equations 1 and 2 show the hydration reactions of portland cement.Calcium silicate hydrate (C-S-H) is the major contributor to concrete strength. SCMs such asslag cement and fly ash contain amorphous silica (S) which reacts (Equation 3) with calciumhydroxide (CH) to form additional C-S-H thereby improving strength. The equations shownbelow are in ceramic notation. 2C3S + 11H → C-S-H + 3CH (1) 2C2S + 9H → C-S-H + CH (2) CH + S + H → C-S-H (3)In addition to improving hardened concrete properties, SCMs are also used to produce “green”structures.

This change of state has the potential to revolutionize thecontrol aspects and responsiveness of hydraulic power transmission.Research during the 1960’s and 70’s was focused on devices such as: satellite antennas(NASA) that would unfold and expand when exposed to the heat of the sun; engines thatwould run on hot and cold water; automatic temperature-controlled greenhouse windows; Page 11.922.2and car fan clutches that would engage only when the engine warmed-up.One of the

. Another distinct advantagewith CAD visualization involves being able to modify the problem. As an example, whathappens to the tension in the cables if the angles of cables A and B are increased or decreased?Can you visualize that from the picture?Another basic problem which would not intimidate a CAD novice involves EngineeringDynamics to include the mysterious “acceleration” term which tends to bewilder students. Theproblem focuses on determining the total acceleration of a sliding collar on a straight rod rotatingabout a vertical axis when the rod’s current position is at 45° as shown in Figure 2 on the left. Atthis instant, the point P on the collar has a outward velocity along the rod of 4 m/s (relative to therod as shown) when the distance

Figure 4.The controller must interface with the DC motors through an H-Bridge structure. A complexprogrammable logic device (CPLD) feeds the H-Bridge with two signals, S for activating themotor and D for the direction of the rotor movement. The duration of the signal S is calculatedbased on the amount of rotation required for every angular step and on the gear ratio selected forthe gear motor, and the panel-to-motor transfer gear ratio.Initially, once the location is selected, the azimuth angle range is determined with a tilt angle θcalculator, and the angular step value is subsequently set. The total number of tilt steps is 12 (6 ineach direction) for covering the whole calendar year. During the course of the year, the arraywill be tilted

By sectionalizing the fuselage, wings,tail, control surfaces, and other independent surfaces, individual forces are then calculated in realtime into a resultant force that is worked into a function of velocity to give an accurate real timeflight model.According to the creators, the software calculates its flight model using BEMT in the followingorder:a) Element Break-DownX-Plane™ breaks the wing(s), horizontal stabilizer, vertical stabilizer(s), and propeller(s) (ifequipped) down into a finite number of elements.b) Velocity DeterminationThe aircraft linear and angular velocities, along with the longitudinal, lateral, and vertical armsof each element are considered to find the velocity vector

A highlyprecision voltage source, accurate electrical components including electronically embeddedcontact lens, and a sophisticated analyzing system such as precision current monitor will be usedin this study. The contact lens glucose sensing method introduced in this work can beminiaturized using current integrated circuit and semiconductor technology, and has the potentialto provide a low cost, fast, stable, and compact non-invasive glucose sensor for the diabeticpatients within near future.

This is LED in S/D Circuit (b)possible because the diffusion constant of phosphorous in SiO2 isvery low as compared to that in Si. Thus, the presence of SiO2makes sure that the n-type impurities are introduced in red areas(S/D) only.

. This research study conducted at a PacificNorthwest university sought to understand the extent to which assumptions about climate at theundergraduate and graduate level are true. The study found that while undergraduate andgraduate women in engineering deal with some of the same climate issues, the contextualdifferences relative to faculty interactions and classroom experiences were significant in howclimate is perceived. The differences in perceptions about climate speak to the fact that a one-size solution does not fit all, and policy changes must account for the contextual differences inthe education of female undergraduate and graduate students.IntroductionFirst coined by Hall & Sandler in the early 1980’s to describe the classroom

The paper includes qualitative results from a survey regardingstudent preferences for the new class structure in comparison to the previousstructure.1. BackgroundHistorically, engineering education has been dominated by a lecture only format,in which students are expected to retain and memorize lecture material,reproducing it on demand for exams1. This one-way transfer of information fromteacher to student has been termed the “banking concept of education” by PauloFreire2.In the 1970’s Feire criticized “banking education” for its inability to activelyinvolve the students as critical thinkers. Freire viewed banking education as aform of
