Abstract

Purpose

The purpose of this paper is to develop a kind of low cost measuring system based on binocular vision sensor to detect both the weld pool geometry and root gap simultaneously for robot welding process.

Design/methodology/approach

Two normal charge coupled device cameras are used for capturing clear images from two directions; one of them is used to measure the root gap and another one is used to measure the geometric parameters of the weld pool. Efforts are made from both hardware and software aspects to decrease the strong interferences in pulsed gas tungsten arc welding process, so that clear and steady images can be obtained. The grey level distribution characteristics of root gap edge and weld pool edge in images are analyzed and utilized for developing the image processing algorithms.

Findings

A solid foundation for seam tracking and penetration control of robot welding process can be established based on the binocular vision sensor.

Practical implications

The results show that the algorithms can extract the root gap edges and the contour of weld pool effectively, and then some geometric parameters can be calculated from the results.

Originality/value

The binocular vision system provides a new method for sensing of robot welding process.

Abstract

With precursor software dating to 1972, multi‐LIS became the first commercially available, fully integrated library system in North America to run on the Unix operating system. In 1988, multiLIS developers, Sobeco Ernst & Young Inc. (SEY), ported multiLIS software to the MIPS Reduced Instruction Set Computer (RISC) processor, making it the First fully integrated software program to be available on a RISC platform. multiLIS fully supports both CAN/MARC and USMARC as well as the monographs specifications of UNIMARC. As the multiLIS software was developed in a resource‐sharing environment, consortiums are a natural market for the multiLIS product.

Abstract

Global/national policy planning is guided by economic methods and predictions of growth, where indicators of success are measured according to a dominant view of progress and sustainable development. Yet, despite widespread ratification of the Declaration on the Rights of Indigenous Peoples, Indigenous Peoples remain unrepresented in this dominant view. The structural and historical forces informing global policy thus inadvertently produce a pathway of development that is characterized by political, economic, and social exclusion where Indigenous Peoples’ agency, heritage, and culture remain marginalized. I argue that socio-cultural nuance (“the complete story”) is critical to policy planning if we are to honor the principal aim of the Sustainable Development Goals – “leave no-one behind”. This and other policy frameworks need an approach that is neither framed by Eurocentric objectives nor bound by measurable indicators. This requires consideration of Indigenous Worldviews in a way that mediates diverse social, economic, and political factors. In this chapter, I examine the limitations in current policy consultation practice, with a specific focus on the extractive industries sector, and examine the ways in which engagement with Indigenous Peoples’ “complete story” might inform policy in the pursuit of a sustainable development that leaves no-one behind and creates a bridge between dominant and marginalized forms of knowledge.

Abstract

Purpose

Production of waste has been increased exponentially due to world industrialization and urban and machine life expansion. On the other hand, the outbreak of the COVID-19 coronavirus quickly became a global crisis. This crisis has added a large amount of waste to urban waste. The purpose of this study is to create cooperation between municipal waste collector contractors.

Design/methodology/approach

Thus, a mathematical model is proposed under uncertain conditions, which includes the volume of municipal waste and infectious waste including personal protective equipment and used equipment for patients. To reduce total costs, the results are evaluated with four cooperative game theory methods such as Shapley value, t value, core center and least core. Ultimately, the saved cost by cooperation in each coalition is allocated fairly among the contractors. Finally, a comparison was made between the solution methods based on the value of the objective function and the solution time.

Findings

The results indicate that the proposed cooperative method increases cost savings and reduces the fine of residual waste. Therefore, it can be mentioned that this kind of cooperation would finally result in more incentives for contractors to form larger coalitions. Genetic algorithms were used to solve the large-scale model.

Originality/value

The proposed model boosts the current understanding of waste management in the COVID-19 pandemic. The paper adds additional value by unveiling some key future research directions. This guidance may demonstrate possible existing and unexplored gaps so that researchers can direct future research to develop new processes.

Abstract

Purpose

Social marketing has been widely used to effectively and voluntarily change behaviours worldwide. The social marketing benchmark criteria offer a framework to apply this approach. This paper aims to examine the extent of use and predictors of success of social marketing benchmark criteria in changing the health behaviours of Pacific Islands populations.

Design/methodology/approach

A systematic review of studies designed to change health behaviours among Pacific Islands populations. Studies were assessed against the social marketing benchmark criteria to determine the extent to which the reported intervention used a social marketing approach; and whether the use of the social marketing benchmark criteria led to more effective interventions.

Findings

In total, 22 studies were included. In total, 13 were conducted within the Pacific Islands and 9 were aimed at Pacific Islands populations living in America, New Zealand or Hawaii. The most common criteria used were behaviour change, insight and customer orientation. Theory criterion was least commonly used. There was no clear indication of which criterion or combination of criteria, resulted in more effective interventions.

Research limitations/implications

Further empirical evaluations of social marketing interventions within the Pacific Islands context are required to appropriately assess effective predictors of success for this population group. Studies of social marketing interventions targeting non-Pacific Islands populations in non-Pacific Island countries and territories may have limited applicability to Pacific Islanders living in Pacific Island countries and territories.

Originality/value

While similar studies have been conducted, this is the first study to review all behaviour change interventions by applying a social marketing lens in the Pacific Islands. While globally this may have been reviewed, the Pacific Islands has a unique context that needs to be considered, rather than assuming a one size fits all approach. This study offers a comprehensive overview of existing health behaviour change interventions in the Pacific Islands and a call to action to move social marketing forward within the Pacific Islands.
