One of the goals of using robots in introductory programming courses is to increase motivation among learners. There have been several types of robots that have been used extensively in the classroom to teach a variety of computer science concepts. A more recently introduced robot designed to teach programming to novice students is the Institute for Personal Robots in Education (IPRE) robot. The author chose to use this robot and study its motivational effects on non-computer science students in a CS0 course. The purpose of this study was to determine whether using the IPRE robots motivates students to learn programming in a CS0 course. After considering various motivational theories and instruments designed to measure motivation, the author used Keller's Instructional Materials Motivation Survey to measure four components of motivation: attention, relevance, confidence, and satisfaction. Additional items were added to the survey, including a set of open-ended questions. The results of this study indicate that the use of these robots had a positive influence on participants' attitudes towards learning to program in a CS0 course, but little or no effect on relevance, confidence, or satisfaction. Results also indicate that although gender and students interests may affect individual components of motivation, gender, technical self-perception, and interest in software development have no bearing on the overall motivational levels of students. © 2012 ACM 1946-6226/2012/03-ART4 $10.00.

This paper further explores the topic of an ideal heat exchanger, which is still an open question. It is shown that the minimization of entropy production or exergy destruction should not be an objective in heat exchanger design. It is further proven that heat exchanger effectiveness does not correlate with irreversibility. A new performance measure, entropy flux, is introduced and a general expression for its evaluation is presented. It is shown that entropy flux captures many desirable attributes of heat exchangers. For a given effectiveness, a single stream heat exchanger has the absolute maximum entropy flux, and for capacity ratios greater than zero, counterflow has the highest entropy flux, parallel flow the lowest, and the shell and tube heat exchangers are somewhere in between. © 2010 American Society of Mechanical Engineers.

This paper presents a survey on embedded systems design and applications. Several platforms for embedded systems, including microcontrollers, microprocessors, field-programmable gate arrays, digital signal processors, and application-specific integrated circuits are discussed and compared. A survey of embedded system-based industrial applications is presented. Examples of real-life design decisions specific to development of such systems are also presented. The carefully selected three design case study examples include industrial control of wind tunnel with emphasis on actuator control, a mobile robot navigation system with emphasis on integration and synchronization of several subsystems, and optimized implementation of computationally intensive control system on a small microcontroller system. © 2011 IEEE.

Evolutionary psychologists have hypothesized that humans possess sex-differentiated mate preference adaptations. In the context of long-term mating, men are hypothesized to more strongly prefer cues to youth and fecundity, whereas women are hypothesized to more strongly prefer cues to status-related attributes. Eastwick, Luchies, Finkel, and Hunt (2014) recently asserted that if men and women evolved sex-differentiated desires, they should exhibit similarly sex-differentiated relational outcomes such as marital satisfaction in response to whether a partner fulfills those desires. This seemingly reasonable extrapolation from sex differences in mate preferences to sex differences in relationship outcomes is, from an evolutionary perspective, problematic and warrants careful conceptual analysis. Evolutionary psychologists have not predicted that selecting a mate with sex-differentiated desirable qualities always translates to more satisfying, trusting, and passionate relational outcomes. Indeed, in some cases obtaining an ideal partner is expected to lead to negative outcomes, such as incurring the costs of heightened courtship effort, mate retention exertion, and the painful experience of jealousy. There are 4 additional concerns with the Eastwick et al. analysis: (a) heterogeneous operationalizations of predictor and criterion variables, (b) inadequate treatment of individual differences in the expression of evolved mate preferences, (c) an overlooking of physical appearance cues central to women's long-term mate preferences, and (d) the impact of nonrandom mateship formation on sex-linked variances in preferred attributes (e.g., low status men and unattractive women may be underrepresented in studies of established couples). As conducted, the Eastwick et al. analyses, while valuable, did not adequately test functionrelated hypotheses derived from the evolutionary psychology of mate preferences. © 2014 American Psychological Association.

A heat transfer apparatus and related methods are provided. The heat transfer apparatus and related methods more precisely distribute fluid flow to meet heat removal needs in single-phase and/or a two-phase heat exchange systems by restricting fluid flow through one or more heat exchanger channels.
