How can we help college students develop problem-solving skills in engineering? To answer this question, we asked a group of engineering freshmen to learn about electrical circuit analysis with an instructional program that presented different problem-solving practice and feedback methods. Three findings are of interest. First, students who practiced by solving all problem steps and those who p...

This work is devoted to the study of the existence and smoothness of the marginal densities of the solution of one dimensional backward stochastic differential equations. Under monotonicity conditions of a function of the coefficients, we obtain that the smoothness properties of the forward process influencing the backward equation, transfer to the densities of the solution. Once established th...

Abstract The convective heat transfer and flow field characteristics through a backward-facing step (BFS) channel combined with corrugated wall is investigated numerically experimentally. Uniform flux applied on 200 mm of the downstream wall, while rest walls are considered isolated surfaces. range Reynolds number (Re) was between 5000 20,000. governing equations were solved using RNG k ? e tur...

Metacognitive skills have been commonly associated with preparation for future learning in deductive domains. Many researchers regarded strategy- and time-awareness as two metacognitive that address how when to use a problem-solving strategy, respectively. It was shown students who are both time-aware (StrTime) outperformed their nonStrTime peers across In this work, were trained on logic tutor...

Polydimethylsiloxane (PDMS) is a silicone-elastomer that owes its large application in the field of stretchable electronics to chemical and thermal stability, transparency, flexibility, non-toxicity, compatibility, low cost. PDMS versatile material because it can be used both as an elastic substrate and, after functionalization, active for design electronics. One possible route functionalizatio...

Methods of measuring the acoustic behavior of tubular systems can be broadly characterized as steady state measurements, where the measured signals are analyzed in terms of infinite duration sinusoids, and reflectometry measurements which exploit causality to separate the forward and backward going waves in a duct. This paper sets out a multiple microphone reflectometry technique which performs...

The accuracy of saccadic eye movements is maintained over the long term by adaptation mechanisms which decrease or increase saccade amplitude. It is still unknown whether these opposite adaptive changes rely on common mechanisms. Here, a double-step target paradigm was used to adaptively decrease (backward second target step) or increase (forward step) the amplitude of reactive saccades in one ...
