This paper examines the implications for research into the diffusion of innovations (DOI) arising from a growing body of literature in two related fields. The first area concerns the debate on the role of regional and national systems of innovation (NSI) in the innovation process. The second area deals with the argument that enterprises must move from a “closed innovation” to an “open innovatio...

Multiple Motion Analysis for Intelligent Video Surveillance

The determination of the visual field for several persons in a scene is an important problem with many applications in human behavior understanding for security and customized marketing. One such application, addressed in this paper, is to catch the visual field of persons in a scene. We obtained the head pose in the image sequence manually in order to determine exactly the visual field of pers...

Automatic abnormality detection in video sequences has recently gained an increasing attention within the research community. Although progress has been seen, there are still some limitations in current research. While most systems are designed at detecting specific abnormality, others which are capable of detecting more than two types of abnormalities rely on heavy computation. Therefore, we p...

We prove in a uniform way that all Denjoy–Carleman differentiable function classes of Beurling type C(M) and of Roumieu type C{M}, admit a convenient setting if the weight sequence M = (Mk) is log-convex and of moderate growth: For C denoting either C(M) or C{M}, the category of C-mappings is cartesian closed in the sense that C(E, C(F,G)) ∼= C(E × F,G) for convenient vector spaces. Application...

This article critically examines developments in CCTV (Closed Circuit Television) policy and provision in the UK, with specific reference to the ‘evidence-based’ approach to policymaking and service provision. The main features of the CCTV revolutions are examined from a policy perspective, so that intertwined changes in purpose and technological configuration are illuminated. The underlying pr...

Video surveillance systems must support multiple streaming and prompt alert notification. We propose a two-tiered environment: a supervisor defines presentation layouts and model interface reactions to alerts; a surveillant watches synchronized videos, adapts layouts, and is notified with alerts.

We present methods to stabilize a class of motion patterns for unit speed particles in the plane. From their initial positions within a compact set in the plane, all particles converge to travel along a closed curve. The relative distance between each pair of particles along the curve is measured using the relative arc-length between the particles. These distances are controlled to converge to ...
