Spatial ability training is useful in developing problem solving skills in engineering drawing (ED). Mental rotation (MR) is a substantial part of spatial abilities. In a previous work we described a three-hour computer based 3D MR training module and showed that it improves MR skills of first year engineering undergraduates. In this paper, we present a study on the effectiveness of a two-week computer based 3D MR training on students' problem solving skills in ED. We performed a two-group experimental study and found that students who learned via computer based 3D MR training performed significantly better on ED posttests than students who learned the same concepts via traditional instruction. Responses of experimental group students on an open ended question revealed that they found the 3D MR training to be useful in resolving their ED problem solving difficulties.

Multi-crease self-folding by global heating

Multi-crease self-folding by global heating

This study demonstrates a new approach to autonomous folding for the body of a 3D robot from a 2D sheet, using heat. We approach this challenge by folding a 0.27-mm sheetlike material into a structure. We utilize the thermal deformation of a contractive sheet sandwiched by rigid structural layers. During this baking process, the heat applied on the entire sheet induces contraction of the contracting layer and thus forms an instructed bend in the sheet. To attain the targeted folding angles, the V-fold spans method is used. The targeted angle θout can be kinematically encoded into crease geometry. The realization of this angle in the folded structure can be approximately controlled by a contraction angle θin. The process is non-reversible, is reliable, and is relatively fast. Our method can be applied simultaneously to all the folds in multi-crease origami structures. We demonstrate the use of this method to create a lightweight mobile robot. © 2015 Massachusetts Institute of technology.

Students who have studied in their native language face difficulty in acquiring programming skills through English medium instruction. One solution for this is to create screen casts of live coding along with instructor explanations in the native language. In this paper we examine the impact of screen cast based self-paced learning for Hindi medium (native language) students. Our study had three groups - One group had Hindi as the medium of prior instruction, and learned programming through screen casts in Hindi. Another group, also had Hindi as the medium of prior instruction, but learned through screen casts in English. The third group had English as the medium of prior instruction, and learned through screen casts in English. We compared the performance of the three groups using a post-test having items of fact, concept and process content types. We found that Hindi medium students who studied from Hindi screen casts performed as well as English medium students who studied from English screen casts. Both groups performed better than Hindi medium students who studied from English screen casts. The effect of medium of instruction was significant for the content types of fact, process and concept.

The vibration in induction motors is due to mechanical and electrical forces existing during the motor operation. The vibration monitoring can help to prevent wear in motors, to increase its efficiency and lowering maintenance costs. Through knowledge and accurate diagnostic procedures, it is possible to detect the cause of the vibration. This paper presents the vibration measurement analysis in the induction motor running at no-load condition using a biaxial optical fiber accelerometer. The sensor is positioned on the induction motor, and the acquired data compared with the one from a capacitive sensor. Changing the power supply frequency from 10 to 60 Hz a higher SNR was observed for both directions on the optical sensor data. The characteristics of the optical sensor, immunity to electromagnetic interference and high sensitivity, 87.848 pm.g-1 and 92.351 pm.g-1 for two directions and independent directions, favors its use for monitoring vibrations in electrical machines. The results indicate a relation between deterioration and mechanical vibration and, thus, providing the motivation for additional study and a basis for future applications. © 2015 IEEE.

This paper shows the application of the Differential Evolution algorithm to the recovery of the deformation profile applied to a fiber Bragg grating sensor (FBG). The method uses only the sensor reflectivity, without the need of phase information, and has been shown to be highly parallelizable. The method was specially implemented to run the complex computations required by the fitness function using a Graphical Processing Unit (GPU). This provided an enhancement of 3 orders of magnitude in the computation time when compared to similar methods shown in literature. Three experiments were performed to evaluate the computational performance of the DE algorithm, and its convergence of the solution to the target deformation profile. Overall, the method is very promising and it can be applied to problems that require a fast response, such as the online monitoring of FBG sensors.

COnstraint-Based Reconstruction and Analysis (COBRA) provides a molecular mechanistic framework for integrative analysis of experimental data and quantitative prediction of physicochemically and biochemically feasible phenotypic states. The COBRA Toolbox is a comprehensive software suite of interoperable COBRA methods. It has found widespread applications in biology, biomedicine, and biotechnology because its functions can be flexibly combined to implement tailored COBRA protocols for any biochemical network. Version 3.0 includes new methods for quality controlled reconstruction, modelling, topological analysis, strain and experimental design, network visualisation as well as network integration of chemoinformatic, metabolomic, transcriptomic, proteomic, and thermochemical data. New multi-lingual code integration also enables an expansion in COBRA application scope via high-precision, high-performance, and nonlinear numerical optimisation solvers for multi-scale, multi-cellular and reaction kinetic modelling, respectively. This protocol can be adapted for the generation and analysis of a constraint-based model in a wide variety of molecular systems biology scenarios. This protocol is an update to the COBRA Toolbox 1.0 and 2.0. The COBRA Toolbox 3.0 provides an unparalleled depth of constraint-based reconstruction and analysis methods.

Sand production in petroleum wells is a major concern for the petroleum industry. Sand production results in erosion of pipelines and damage to equipment which may lead to production shutdown and large economic losses. Detection of produced sand is important for optimizing flow rates and measuring the success of sand mitigation techniques. Recently, microwave nondestructive testing was considered as a potential new sensing solution for the detection of sand production. This paper presents preliminary simulations and measurements for such a sensing approach using open-ended waveguides. Different production scenarios are considered for a stratified flow regime. The results indicate that this sensing method can detect the presence of sand. Preliminary measurements are also presented for varying amounts of sand that further support the potential of this technique.
