The vast majority of work to date concerned with obstacle avoidance for manipulators has dealt with task descriptions in the form ofpick-and-place movements. The added flexibility in motion control for manipulators possessing redundant degrees offreedom permits the consideration of obstacle avoidance in the context of a specified end-effector trajectory as the task description. Such a task defi...

Dynamic reconfiguration of digital circuits on FPGAs has been an area of active research for the past decade. The identification of generic classes of circuits that would benefit from being dynamically reconfigured remains a key, open problem. We report on an investigation of the application of dynamic reconfiguration to programmable, multi-function cores (PMCs). An abstract analysis of the tec...

In this talk I report on recent work related to the dynamical generation of baryonic resonances, some made up from pseudoscalar meson-baryon, others from vector meson-baryon and a third type from two meson-one baryon systems. We can establish a correspondence with known baryonic resonances, reinforcing conclusions previously drawn and bringing new light on the nature of some baryonic resonances...

In this paper we present closed-form solutions for efficiently updating the prin-cipal components of a set of n points, when m points are added or deleted fromthe point set. For both operations performed on a discrete point set in R, we cancompute the new principal components in O(m) time for fixed d. This is a signifi-cant improvement over the commonly used approach of reco...

The Multimedia Information Presentation System (MIPS) will allow end-users to browse multimedia information presented in a user-friendly and consistent manner. In its most powerful configuration, it will allow the end-user to formulate queries which are interpreted, analysed , and despatched by the system to heterogeneous distributed external data sources, and to view a coherent and customized ...

Dynamically typed languages such as Python and Ruby have experienced a rapid grown in popularity in recent times. However, there is much confusion as to what makes these languages interesting relative to statically typed languages, and little knowledge of their rich history. In this chapter I explore the general topic of dynamically typed languages, how they differ from statically typed languag...

There is extensive literature on inferring loop invariants statically (i.e. without explicitly executing the program under analysis). We report on a new dynamic technique for inferring loop invariants based on the invariant detector Daikon [2]. Unlike InvGen [4], this new technique follows a counter example guided approach for refining candidate loop invariants. Let us consider the following an...

We present a detailed discussion of a novel dynamical renormalization group scheme: the Dynamically Driven Renormalization Group (DDRG). This is a general renormalization method developed for dynamical systems with non-equilibrium critical steady-state. The method is based on a real space renormalization scheme driven by a dynamical steady-state condition which acts as a feedback on the transfo...

Dynamically Reconfigurable Resource Array DRRA is an architecture concept that is in tune with the technology trend: exponentially increasing device density due to shrinking geometry, 3D integration and potential new device structures in future. DRRA’s objectives are: 1. Radically improve performance/energy metric: Minimize movement of data, 2. Simplify the programming model to exploit the mass...
