Vision-based control for mining automation

The mining industry is highly suitable for the application of robotics and automation technology since the work is both arduous and dangerous. Visual servoing is a means of integrating noncontact visual sensing with machine control to augment or replace operator based control. This article describes two of our current mining automation projects in order to demonstrate some, perhaps unusual, applications of visual servoing, and also to illustrate some very real problems with robust computer vision

China’s creative industries: Challenges matched by opportunities

Report for the German Chamber of Commerce in China. "China’s growing economic, political, and military capacity is the most geopolitically significant development of the 21st century, which is already being branded ‘the Asian Century.’ Certainly the economic decline of the US and Europe has played directly into the hands of China’s nationalists, who yearn for a return to past glory and who seek symbolic retribution for almost two centuries of foreign oppression and humiliation...."--publisher website

Developing creative services industries in Hangzhou, China

Creativity is changing the People’s Republic of China according to Li Wuwei (2011), a leading Chinese economist and policy advisor. The nation is learning to embrace a “third industrial revolution” (Rifkin, 2011) while banking the economic capital of the carbon-dependent manufacturing economy. Urbanisation is also driving change and consumer culture (Gerth, 2010). Most of China’s high-value creative service industries are found in the large urban centres of Beijing, Shanghai, Guangzhou and Shenzhen in the coastal provinces. China’s second-tier cities, including Hangzhou in Zhejiang province, are also seeking to make capital out of culture, albeit with different strategies than the coastal hubs. The Hangzhou metropolitan area is the fourth largest in China, with 8.8 million residents. Zhejiang province was once known as the “land of rice and fish.” However, with the increased emphasis on productivity in China’s economic reforms since 1978, the province became an economic heavyweight, characterised by small and medium-sized enterprises often working together to produce complementary products...

Creative industries and the wider economy

Researchers have argued that the creative industries have significant effects on the wider economy, with early agendas focused on urban regeneration, job creation, and economic value-added. Later work extended to new firm creation, the growth of new markets, and regional clustering and development. This chapter reviews the evolution of thinking on classifying the creative industries as a ‘sector’, or group of sectors, and outlines contributions on economic ‘spillovers’ regarding knowledge, innovation, and graduate talent. Work on creative clusters has highlighted the widespread adoption of forms of organization and contracting developed in such clusters. Later work by the authors has contributed a ‘creative trident’ model, and shifted focus to employment and the position of creative workers in the economy, showing that there are more creatives working outside the creative industries than within them. The chapter reflects on the specific role of design and the relationship between the creative industries and innovation.

From ImageNet to mining: Adapting visual object detection with minimal supervision

This paper presents visual detection and classification of light vehicles and personnel on a mine site.We capitalise on the rapid advances of ConvNet based object recognition but highlight that a naive black box approach results in a significant number of false positives. In particular, the lack of domain specific training data and the unique landscape in a mine site causes a high rate of errors. We exploit the abundance of background-only images to train a k-means classifier to complement the ConvNet. Furthermore, localisation of objects of interest and a reduction in computation is enabled through region proposals. Our system is tested on over 10km of real mine site data and we were able to detect both light vehicles and personnel. We show that the introduction of our background model can reduce the false positive rate by an order of magnitude.

Creative interoperability: A new concept to guide, understand and evaluate innovation by cross-sector collaboration

Creative digital media are increasingly utilized by companies in all industries. Here cases studies of creative media innovations in manufacturing, mining and education were facilitated and evaluated. The cases dealt respectively with designs in manufacturing, visualizing mining data, and developing tools for adult literacy. The difficulties of merging creative media teams into these different contexts were noted and the idea of creative interoperability was developed. Creative interoperability explains how creative teams can connect with other disciplines to bring about innovations.

Applications of real-time machine vision to the control of mining equipment

The mining industry presents us with a number of ideal applications for sensor based machine control because of the unstructured environment that exists within each mine. The aim of the research presented here is to increase the productivity of existing large compliant mining machines by retrofitting with enhanced sensing and control technology. The current research focusses on the automatic control of the swing motion cycle of a dragline and an automated roof bolting system. We have achieved: * closed-loop swing control of an one-tenth scale model dragline; * single degree of freedom closed-loop visual control of an electro-hydraulic manipulator in the lab developed from standard components.

Journal of Education and Work: Special Issue: Creative Graduate Pathways Within and Beyond the Creative Industries

This special issue explores the nuances of graduate creative work, the kinds of value that creative graduates add through work of various types, graduate employability issues for creative graduates, emerging and developing creative career identities and the implications for educators who are tasked with developing a capable creative workforce. Extant literature tends to characterise creative careers as either ‘precarious’ and insecure, or as the engine room of the creative economy. However, in actuality, the creative workforce is far more heterogeneous than either of these positions suggest, and creative careers are far more complex and diverse than previously thought. The task of creative educators is also much more challenging than previously supposed.

Jobs for creatives outside the creative industries: A study of creatives working in the Australian manufacturing industry

More creatives work outside the creative industries than inside them. Recent Australian Census data show that 52 per cent of creatives work outside of the core creative industries. These embedded creatives make up 2 per cent of manufacturing industry employees. There is little qualitative research into embedded creatives. This paper aims to address this by exploring the contribution of creative skills to manufacturing in Australia. Through four case studies of designers and marketing staff in lighting and car seat manufacturing companies, this paper demonstrates some of the work that embedded creatives undertake in the manufacturing industry and some of the ways that they contribute to innovation. The paper also considers perspectives embedded creatives bring to manufacturing and challenges involved in being a creative worker in a non-creative industry. This research is important to economic development issues, demonstrating some of the roles of key innovators in an important industry. This work also informs the education of creative industries students who will go on to contribute in a variety of industries. Furthermore, this research exemplifies one industry where employment is available to creatives outside of the creative industries.

Integration of Opinion Mining into customer analysis model

This research proposes a multi-dimensional model for Opinion Mining, which integrates customers' characteristics and their opinions about products (or services). Customer opinions are valuable for companies to deliver right products or services to their customers. This research presents a comprehensive framework to evaluate opinions' orientation based on products' hierarchy attributes. It also provides an alternative way to obtain opinion summaries for different groups of customers and different categories of produces.

Sensors and control for mining robotics

This paper discusses some of the sensing technologies and control approaches available for guiding robot manipulators for a class of underground mining tasks including drilling jumbos, bolting arms, shotcreters or explosive chargers. Data acquired with such sensors, in the laboratory and underground, is presented.

Disruptive innovations in complex product systems industries: A case study

We propose that disruptive changes pertaining to complex product systems (CoPS) will yield a different set of characteristics than those traditionally observed for commodity products, and seek evidence for this proposition in a case study of the Flash Converting technology, a disruptive CoPS innovation in the copper production industry. Our results show that unlike disruptions in commodity product industries, the incumbent CoPS technology does not overshoot mainstream market performance demand. Also, the disruptive CoPS innovation: (i) is not nurtured in low-end niche markets; (ii) initially satisfies mainstream market performance demand, and; (iii) has higher unit price than the incumbent technology.

Pull the plug or take the plunge: Multiple opportunities and the speed of venturing decisions in the Australian mining industry

Effectively capturing opportunities requires rapid decision-making. We investigate the speed of opportunity evaluation decisions by focusing on firms' venture termination and venture advancement decisions. Experience, standard operating procedures, and confidence allow firms to make opportunity evaluation decisions faster; we propose that a firm's attentional orientation, as reflected in its project portfolio, limits the number of domains in which these speed-enhancing mechanisms can be developed. Hence firms' decision speed is likely to vary between different types of decisions. Using unique data on 3,269 mineral exploration ventures in the Australian mining industry, we find that firms with a higher degree of attention toward earlier-stage exploration activities are quicker to abandon potential opportunities in early development but slower to do so later, and that such firms are also slower to advance on potential opportunities at all stages compared to firms that focus their attention differently. Market dynamism moderates these relationships, but only with regard to initial evaluation decisions. Our study extends research on decision speed by showing that firms are not necessarily fast or slow regarding all the decisions they make, and by offering an opportunity evaluation framework that recognizes that decision makers can, in fact often do, pursue multiple potential opportunities simultaneously.

The dynamics of global visual effects and games development industries: lessons for Australia’s creative industries development policy

The paper critiques the focus of creative industries policy on capability development of small and medium sized firms and the provision of regional incentives. It analyses factors affecting the competitiveness and sustainability of the games development industry and visual effects suppliers to feature films. Interviews with participants in these industries highlight the need for policy instruments to take into consideration the structure and organization of global markets and the power of lead multinational corporations. We show that although forms of economic governance in these industries may allow sustainable value capture, they are interrupted by bottlenecks in which ferocious competition among suppliers is confronted by comparatively little competition among the lead firms. We argue that current approaches to creative industries policy aimed at building self-sustaining creative industries are unlikely to be sufficient because of the globalized nature of the industries. Rather, we argue that a more profitable approach is likely to require supporting diversification of the industries as ‘feeders’ into other areas of the economy.

Mining process risks and resource profiles

This research contributes novel techniques for identifying and evaluating business process risks and analysing human resource behaviour. The developed techniques use predefined indicators to identify process risks in individual process instances, evaluate overall process risk, predict process outcomes and analyse human resource behaviour based on the analysis of information about process executions recorded in event logs by information systems. The results of this research can help managers to more accurately evaluate the risk exposure of their business processes, to more objectively evaluate the performance of their employees, and to identify opportunities for improvement of resource and process performance.
