fuzzy logic control of a two degree of freedom parallel robot
(2010)parallel robots differ greatly from their serial counterparts in terms of performance and mechanical ability. serial robots are open chained mechanisms since each link is connected to an adjacent one and each joint is ... -
reconstructing childhood and adulthood diets from a caribbean population using stable carbon and nitrogen isotope analysis of dentin and bone collagen
(2012-11-10)the purpose of this study was to establish stable carbon (c) and nitrogen (n) isotope signatures for the 43 individuals in this study population using bone and dentin collagen, and extrapolate the isotopic data to dietary ... -
ecological concept development at the elementary school level
(2012)this case study of one school was designed to examine the level of knowledge and understanding elementary 世界杯2022赛程表淘汰赛 (ages 9 – 13) have for key ecological concepts that are found in the ontario 2007 science curriculum ... -
lignin degradation by some wood-rot fungi with emphasis on cylindrocladium camelliae
(2012-11-10)thirty wood-rot fungi were screened for their ability to grow on media containing kraft lignin with a limited amount of glucose. of these fungi, twenty-three were tested for ligninolytic activity judged by decolorization ... -
concepts, theories and models of succession in the boreal forest of central canada
(2009)predicting plant community compositional responses to changing environmental conditions and disturbances is a key element of forecasting and managing for the effects of global climate change. with advances in ecological ... -
context aware services for smart learning environments
(2009)this thesis describes a cost-effective infrastructure and implementation for building ubiquitous learning spaces. it uses techniques from the semantic web and ubiquitous computing to build a learner-centric service-based ... -
nesting dynamics of the scarlet ibis (eudocimus ruber) in trinidad, west indies
(2009)the effect of human disturbance on colonial waterbirds is a global issue. many colonial waterbirds are migratory, and their protection depends on balancing conservation of their habitats and habits across many regions. ... -
understory species response to partial harvesting in boreal riparian buffers
(2009)in order to preserve valuable riparian functioning, forest harvesting in canada attempts to protect riparian areas through the application of a no-harvest buffer zone around water bodies, and more recently through the ... -
selecting locations for forest fuel treatments using simulation optimization
(2009)wildfires in the canadian boreal forest poses a considerable threat to forest inventory, structures and human lives. traditional reactive methods of fire suppression fail to mitigate this threat and can worsen the problem ... -
