This paper proposes an optimisation of the adaptive Gaussian mixture background model that allows the deployment of the method on processors with low memory capacity. The effect of the granularity of the Gaussian mean-value and variance in an integer-based implementation is investigated and novel updating rules of the mixture weights are described. Based on the proposed framework, an implementation for a very low power consumption micro-controller is presented. Results show that the proposed method operates in real time on the micro-controller and has similar performance to the original model. © 2012 Springer-Verlag.

A novel cost-effective and low-latency wormhole router for packet-switched NoC designs, tailored for FPGA, is presented. This has been designed to be scalable at system level to fully exploit the characteristics and constraints of FPGA based systems, rather than custom ASIC technology. A key feature is that it achieves a low packet propagation latency of only two cycles per hop including both router pipeline delay and link traversal delay - a significant enhancement over existing FPGA designs - whilst being very competitive in terms of performance and hardware complexity. It can also be configured in various network topologies including 1-D, 2-D, and 3-D. Detailed design-space exploration has been carried for a range of scaling parameters, with the results of various design trade-offs being presented and discussed. By taking advantage of abundant buildin reconfigurable logic and routing resources, we have been able to create a new scalable on-chip FPGA based router that exhibits high dimensionality and connectivity. The architecture proposed can be easily migrated across many FPGA families to provide flexible, robust and cost-effective NoC solutions suitable for the implementation of high-performance FPGA computing systems. © 2011 IEEE.

This paper discusses the opposition to the disposal of Syrian chemical weapons in the Mediterranean Sea. Following insights from Green criminology and recent calls in that discipline for the inclusion of new social movements and resistance, it discusses in detail how the issue was framed in terms of environmental and ecological justice by different protest actors. This process is aided by an analytical model that brings together the sociology of protest and social movements, insights from reflexive modernisation and the study of southern European civil societies. Methodologically, the focus is on mobilisations that took place in Greece in general and the island of Crete in particular. Data have been harvested through the examination of online sources, such as newspapers, blogs and dedicated social networks. The analysis of the findings suggests that these mobilisations were initially stimulated by real concern, but subsequently these were only carried through by certain movement entrepreneurs who didn’t hesitate to pepper these concerns with false claims and/or linkages to an already active anti-imperialist discourse.

Neoliberal capitalism and its accompanied austerity measures has had a profound effect on social reproduction throughout Europe. Social reproduction, ie, the process that makes it possible for individuals, families, and society to reproduce itself – is in crisis. The concept of social reproduction utilized in this presentation is framed within the feminist and Marxist tradition. Historically, social reproduction was met through both waged and unwaged work with women playing a predominant role either as waged, predominantly public sector, workers (social workers, teachers, carers, nurses, etc) or as unpaid workers (unpaid carers: mothers, wives, etc.) but now both forms of work are destabilized and undermined. Thus, the crisis in social reproduction. Within this crisis women’s unequal position is further undermined but at the same time progressive women and men are organizing to present alternatives forms of social reproduction. This presentation by utilizing the case of Greece will first outline the neoliberal processes that have caused the crisis in social reproduction. Second, it will present the consequences of social reproduction by highlighting the gender implications. Third, it will discuss the reorganization of social reproduction which is taking place outside the logic of capitalist society and is manifested through the creation of solidarity health clinics and pharmacies, communal kitchens, creation of various forms of bartering etc. This presentation will argue that these forms present glimpses of another society , a society based on principles of solidarity and cooperation. A society worth fighting for. And finally the presentation will conclude by discussing at which level can this crisis be resolved and the role of the social work profession.
