Nature's engineering of wood through genetics, stand conditions , and environment creates wide variability in wood as a material, which in turn introduces difficulties in wood processing and utilization. Manufacturers sometimes find it difficult to consistently process wood into quality products because of its wide range of properties. The primary objective(More)
a r t i c l e i n f o a b s t r a c t We present a detailed semantics for linguistic spatial expressions supportive of computational processing that draws substantially on the principles and tools of ontological engineering and formal ontology. We cover language concerned with space, actions in space and spatial relationships and develop an ontological(More)
For AOP (Agent Oriented Programming) to become a mature discipline, lessons must be learned from practical language implementations. We present AF-APL (AgentFac-tory-Agent Programming Language) as an Agent Oriented Programming Language that has matured with continued revisions and implementations, resulting in a language-which, although based on the more(More)
This guide was prepared to assist field foresters in the use of stress wave timing instruments to locate and define areas of decay in standing timber. The first three sections provide background information, the principles of stress wave non-destructive testing, and measurement techniques for stress wave nondestructive testing. The last section is a(More)
This paper describes the general concept of Route Graphs, to be used for navigation by various agents in a variety of scenarios. We introduce the concept of an ontology and describe the modelling of general graphs as an example. This approach is then applied to define a " lightweight " ontology of Route Graphs in an indoors environment, giving at first just(More)
Establishing a clean relationship between a robot's spatial model and natural language components is a non-trivial task, but is key to designing verbally controlled, navigating service robots. In this paper we examine the issues involved in the development of dialogue controlled navigating robots. In particular, we treat our robots as so-called Shared(More)
PURPOSE Age-related macular degeneration (AMD) is a multifactorial blinding disease in the elderly. LOC387715 harbors a single-nucleotide polymorphism that has an association with AMD. This study was conducted to confirm the association between LOC387715 and AMD and to refine estimates of the impact of this gene variation in using samples from three(More)

The objective of this research was to demonstrate the use of personal computer technology in transverse vibration nondestructive testing techniques. A laptop personal computer with expansion unit was coupled to a 100-lb (45.4-kg) load cell via an analog-to-digital converter. This system was used to collect data from simply-supported lumber specimens(More)
PURPOSE Senescent Ccl2(-/-) mice are reported to develop cardinal features of human age-related macular degeneration (AMD). Loss-of-function single-nucleotide polymorphisms within CX3CR1 are also found to be associated with AMD. The authors generated Ccl2(-/-)/Cx3cr1(-/-) mice to establish a more characteristic and reproducible AMD model. METHODS Single(More)
