Effective indenter radius and frame compliance in instrumented indentation testing using a spherical indenter

We introduce a novel method to correct for imperfect indenter geometry and frame compliance in instrumented indentation testing with a spherical indenter. Effective radii were measured directly from residual indentation marks at various contact depths (ratio of contact depth to indenter radius between 0.1 and 0.9) and were determined as a function of contact depth. Frame compliance was found to depend on contact depth especially at small indentation depths, which is successfully explained using the concept of an extended frame boundary. Improved representative stress-strain values as well as hardness and elastic modulus were obtained over the entire contact depth

Augmented Reality and Motion Capture E-Shopping Usage for Apparel: Webcam Social Shopper

The Webcam Social Shopper is referred to as virtual dressing room software. It features augmented reality (i.e., an interactive method of combining live video with computergenerated data and visualizations) via a webcam and a motion capture system in which hand motions allow the users to virtually navigate backward or forward on-screen to choose clothing (Kincaid, 2009). Augmented Reality and Motion Capture (ARMC) e-shopping focuses on a virtual try-before-buying experience using a webcam (Kincaid, 2009)

Repurchase Loyalty for Customer Social Co-Creation E-Marketplaces

Social co-creation refers to the process of using social networking as a vehicle to carry out customer co-creation engagements (Strohmenger, 2011; Williams, 2010). A market survey of 500 mass customization firms revealed that 73% of mass customizers do not yet provide the ability to share co-creations (co-designs) (Sloan, 2010)

Creation of a 3D Digital Fashion Show with 3D Virtual Prototyping of Clothing

The objective of this class project was to (1) create a plan for the product line, (2) develop 3D virtual prototyping of clothing by combining 2D and 3D visualization software such as Adobe Photoshop and Optitex system, and (3) ultimately create 3D digital fashion shows using 3D technology. The students successfully completed the planning of their own collection, the 3D virtual prototyping of the clothing, and the presentation of a 3D digital fashion show. They indicated that the best aspect of the project was that all the students were able to showcase their finished designs and conceptual ideas. They liked being able to develop virtual prototyping without wasting fabric. For simplified 3D virtual prototyping of clothing, the students were able to easily create 3D animations. However, for complicated 3D virtual prototyping of clothing, involving many patterns and details, the process of creating the 3D animations was very slow, or the 3D animations stopped suddenly and eventually failed. The process required a time commitment

Customer Interface Design for Co-Creation in the Social Era

The term “customer interface” in the context of web-based stores stands for the components offered by e-retailers in order to help customers with easy navigation, information acquisition, and eventually purchasing (Lee & Benbasat, 2001). The purpose of this study was to examine (1) whether aspects of the customer interface design for co-creation, such as (a) character, (b) choice, (c) community, (d) contact interactivity, (e) convenience, and (f) customization, were related to commitment (H2-H7) and (2) whether commitment was related to patronage intention (H1)

Augmented Reality Mobile Apps in Fashion Retail: Expectancy-Value Judgments

This study examined (1) the influence of expectancy-value judgments of uses and gratifications including novelty, fashion/status, sociability, and relaxation on trust in AR apps, (2) the influence of trust in AR apps on usage intention toward AR apps and online/offline store patronage intention, and (3) the moderating effect of consumer self-determination. Mobile users (n = 630) from a U.S. consumer panel completed an online self-administered survey. Structural equation modeling and two-way ANOVA were used for data analysis. This study found that novelty and fashion/status were positively related to trust in AR apps. Sociability was negatively related to trust in AR apps. Trust in AR apps was positively related to usage intention toward AR apps and online/offline store patronage intention. Trust in and usage intention toward AR apps were determinants of online/offline store patronage intention. Consumer self-determination moderated the link between trust in and usage intention toward AR apps and the link between trust in AR apps and online/offline store patronage intention

Virtual Prototyping for Planning from Product Design to Retail Store Visualizations and Simulations

The objective of this class project was to (1) develop virtual prototyping from product design to overall retail store design by combining diverse 2D and 3D visualization software, such as Adobe Photoshop, Optitex, and Visual Retailing’s MockShop, and to (2) create innovative product development and visual merchandising plans

Showrooming, Webrooming, and User-Generated Content Creation: The Moderating Effect of SoLoMo

In comparison with traditional multichannel shoppers, omnichannel shoppers simultaneously use all channels including brick-and-mortar stores, catalogs, web, mobile, and social media, not just one or two channels (Thoma, 2010). Due to the surge in smartphone and tablet purchases as well as increased engagement with user-generated content on social media platforms, showrooming and webrooming are prominent shopping trends among shoppers in omnichannel retail. Showrooming describes the practice of examining products in a brick-and-mortar store but ultimately making the actual purchase online or on a mobile device (Richter, 2013)

Four-neutrino analysis of 1.5km-baseline reactor antineutrino oscillations

The masses of sterile neutrinos are not yet known, and depending on the orders of magnitudes, their existence may explain reactor anomalies or the spectral shape of reactor neutrino events at 1.5km-baseline detector. Here, we present four-neutrino analysis of the results announced by RENO and Daya Bay, which performed the definitive measurements of $\theta_{13}$ based on the disappearance of reactor antineutrinos at km-order baselines. Our results using 3+1 scheme include the exclusion curve of $\Delta m^2_{41}$ vs. $\theta_{14}$ and the adjustment of $\theta_{13}$ due to correlation with $\theta_{14}$. The value of $\theta_{13}$ obtained by RENO and Daya Bay with a three-neutrino oscillation analysis is included in the $1\sigma$ interval of $\theta_{13}$ allowed by our four-neutrino analysis.Comment: 14 pages, 7 figures. arXiv admin note: text overlap with arXiv:1303.617

Optimisation of pipeline route in the presence of obstacles based on a least cost path algorithm and laplacian smoothing

Subsea pipeline route design is a crucial task for the offshore oil and gas industry, and the route selected can significantly affect the success or failure of an offshore project. Thus, it is essential to design pipeline routes to be eco-friendly, economical and safe. Obstacle avoidance is one of the main problems that affect pipeline route selection. In this study, we propose a technique for designing an automatic obstacle avoidance. The Laplacian smoothing algorithm was used to make automatically generated pipeline routes fairer. The algorithms were fast and the method was shown to be effective and easy to use in a simple set of case studies
