In this paper, we introduce a robotic implementation of the theory of graph grammars (Klavins et al., 2005), which we use to model and direct self-organization in a formal, predictable and provably-correct fashion. The robots, which we call programmable parts, float passively on an air table and bind to each other upon random collisions. Once attached, they(More)
Consistency techniques are an ecient w ay o f t a c kling constraint satisfaction problems (CSP). In particular, various arc-consistency algorithms have been designed such as the time optimal AC-4 sequential algorithm of Mohr and Henderson 8]. In this paper, we present a new distributed arc-consistency algorithm, called DisAC-4. DisAC-4 is based on AC-4,(More)
Transient receptor potential melastatin 3 (TRPM3) cation channels are ubiquitously expressed by multiple cells and have an important regulatory role in calcium-dependent cell signalling to help maintain cellular homeostasis. TRPM3 protein expression has yet to be determined on Natural Killer (NK) cells and B lymphocytes. Multiple single nucleotide(More)
A complete system was built for high-performance image compression based on overlapped block transform. Extensive simulations and comparative studies were carried out for still image compression including benchmark images (Lena and Barbara), synthetic aperture radar (SAR) images, and color images. We have achieved consistently better results than three(More)
The National Electronics Manufacturing Initiative's (NEMI) plug and play Factory Project addressed the issues of how to quickly integrate new pieces of electronics assembly equipment into a shop floor line management system and how to manage the vast amounts of data available in today's electronics manufacturing environment. The necessary technical(More)
We are constructing a <italic>workbench</italic> for computational geometry. This is intended to provide a framework for the implementation, testing, demonstration and application of algorithms in computational geometry. The workbench is being written in Smalltalk/V using an Apple Macintosh II. The object-oriented model used in Smalltalk is well-suited to(More)
—Conventional block-based video coding with sub-pixel motion compensation, requires a large pool of memory for storing up-sampled reference frames. The size of this memory for many applications, especially for encoding high definition source materials is a major design consideration. In this paper, the concept of reciprocal block matching is introduced(More)
