Abstract

Purpose

This paper holds a big advantage to enable to recognize faces, regardless of time and place. Also this provides an independent performance of smart phone, because of its process by a computer of third party not by that of the mobile device. In addition, it is desirable to minimize the expensive operations in mobile device with constraint computational power (i.e. battery consumption). Thus, the authors exclude the process of transmission failed from the input device. The paper aims to discuss these issues.

Design/methodology/approach

In this paper, the authors have proposed a new face detection and verification algorithm, based on skin color detection to enable extracting the face region from color images of the mobile phone. And then extracted the facial feature as eigenface, verified whether or not the identity of users is right, applied support vector machine to the region of detected face.

Findings

The experimental results for two datasets show that the proposed method achieves slightly higher efficiencies at the detection and verification of user identity, compared with other method, where varying lighting conditions with complex backgrounds, according to be fast and accurate than any other previous methods.

Originality/value

The proposed algorithm enables to implement fast and accurate search using triangle-square transformation for detection of human faces in a digital still color images, obtained by the mobile device camera under unconstraint environments, using advanced skin color model and characteristic points in a detected face.

Abstract

This article explores the little understood practice of school interior design and the manner in which school interiors give form to ideas about what the work of children and teachers could and should look like. Its focus is a perceived link between the concepts of school work made material in the design of new twenty‐first century learning environments and those expressed in the design of Modernist progressive schools such as Richard Neutra’s Corona Ave, Elementary School, California. The article’s impetus comes from current interest in the inter‐relationship between the design of physical learning environments and pedagogy reform as governments in Australia and internationally, work to transform teaching and learning practices through innovative school building and refurbishment projects. Government campaigns, for example the UK’s Schools for the Future Program and Australia’s Victorian Schools Plan, use a promotional rhetoric that calls for the final dismantling of the cellular classroom with its industrial model of work so that ‘different pedagogical approaches and the different ways that children learn [can] be represented in the design of new learning environments’, in buildings and interiors designed to support contemporary constructivist‐inspired pedagogies.

Abstract

Rapid prototyping systems are controlled by a computer which uses the CAD representation to build parts according to an additive plane layering process. The computer controls a laser beam or a print head, or any process that leads to the formation of a slice of a part using resins, powders, paper, wax or other materials. The original CAD representation is translated into commands to drive the process, and accuracy issues will make or break these emerging technologies. It is therefore important to understand where the errors stem from, what are the issues associated with the software representation formats, and how to minimize or eliminate these errors. Presents a summary of CAD to RP software formats, and explains the accuracy issues associated with the selected representation. Discusses improvements that can be obtained by process modifications.

The paper aims to propose an assembly scheme based on master–slave coordination for a compliant dual-arm robot to complete a peg-in-hole assembly task.

Abstract

Purpose

The paper aims to propose an assembly scheme based on master–slave coordination for a compliant dual-arm robot to complete a peg-in-hole assembly task.

Design/methodology/approach

The proposed assembly scheme is inspired by the coordinated behaviors of human beings in the assembly process. The left arm and right arm of the robot are controlled to move alternately. The fixed arm and the moving arm are distinguished as the slave arm and the master arm, respectively. The position control model is used at the uncontacted stage, and the torque control model is used at the contacted stage.

Findings

The proposed assembly scheme is evaluated through peg-in-hole assembly experiments with different shapes of assembly piece. The round, triangle and square assembly piece with 0.5 mm maximum clearance between the peg and the hole can be assembled successfully based on the proposed method. Furthermore, three assembly strategies are investigated and compared in the peg-in-hole assembly experiments with different shapes of assembly piece.

Originality/value

The contribution of this study is that the authors propose an assembly scheme for a compliant dual-arm robot to overcome the low positioning accuracy and complete the peg-in-hole assembly tasks with different shapes parts.

Abstract

Purpose

This study aims to understand how mode of delivery, online versus face-to-face, affects comprehension when teaching operations management concepts via a simulation. Conceptually, the aim is to identify factors that influence the students’ ability to learn and retain new concepts.

Design/methodology/approach

Leveraging Littlefield Technologies’ simulation, the study investigates how team interaction, team leadership, instructor’s guidance, simulation’s ease of use and previous software experience affects comprehension for both online and face-to-face teaching environments. Survey data were gathered from 514 undergraduate students. The data were then analyzed using structural equation modeling.

Findings

For the face-to-face population, this study found that team interaction, previous software experience, instructor’s guidance and simulation’s ease of use affected student comprehension. This differed from the online population who were only affected by the simulation’s ease of use and instructor’s guidance.

Originality/value

Understanding how the mode of delivery affects comprehension is important as educators develop new online teaching techniques and experiment with innovative technologies like simulation. As demand for online education grows, many instructors find they need to refine their methods to ensure students comprehend the concepts being taught regardless of modality.
