UNLABELLED This article reports the findings of a 3-year epidemiological survey for dementia in an urban community-resident population in Mumbai (Bombay), India, wherein the prevalence of all types of dementia was determined. METHOD The study was conducted in three stages. Stage 1: From a potential pool of 30,000 subjects aged 40 years or more, 24,488(More)
The Drosophila central nervous system derives from neural precursor cells, the neuroblasts (NBs), which are born from the neuroectoderm by the process of delamination. Each NB has a unique identity, which is revealed by the production of a characteristic cell lineage and a specific set of molecular markers it expresses. These NBs delaminate at different but(More)
Reinforcement learning, in general, has not been totally successful at solving complex real-world problems which can be described by nonlinear functions. However, temporal difference learning is a type of reinforcement learning algorithm that has been researched and applied to various prediction problems with promising results. This paper discusses the(More)
—Autonomous mobile robots (AMRs) operating in unknown environments face twin challenges: 1) localization and 2) efficient directed navigation. This paper describes a two-tiered approach to solving these challenges: 1) by developing novel wireless-sensor-network (WSN)-based localization methods and 2) by using WSN–AMR interaction for navigation. The goal is(More)
— We propose that robot perception is enabled by means of a common sensorimotor semantics arising from a set of symmetry theories (expressed as symmetry detectors and parsers) embedded a priori in each robot. These theories inform the production of structural representations of sensorimotor processes, and these representations, in turn, permit perceptual(More)
This review identifies the research findings in the area of computer mediated, collocated, multidisciplinary collaborative design. After a general look into this and related research areas, three influencing aspects of collaborative design are reviewed. Design activities, working together, and collaborative systems that fit into various work practices.(More)
— Robot manipulator designs are increasingly fo-cused on low cost approaches, especially those envisioned for use in unstructured environments such as households, office spaces and hazardous environments. The cost of angular sensors varies based on the precision offered. For tasks in these environments, millimeter order manipulation errors are unlikely to(More)
The colossal amount of digitized information available has resulted in overloading users who need to navigate this information for their routine requirements. Information filtering deals with monitoring text streams to detect patterns and retrieval of documents by searching for patterns over stored data. Although information filtering systems and search(More)
