The sounds generated by a writing instrument ("pen-chant") provide a rich and under-utilized source of information for pattern recognition. We examine the feasibility of recognition of handwritten cursive text, exclusively through an analysis of acoustic emissions. We design and implement a family of recognizers using a template matching approach, with templates and similarity measures derived variously from: smoothed amplitude signal with fixed resolution, discrete sequence of magnitudes obtained from peaks in the smoothed amplitude signal, and ordered tree obtained from a scale space signal representation. Test results are presented for recognition of isolated lowercase cursive characters and for whole words. We also present qualitative results for recognizing gestures such as circling, scratch-out, check-marks, and hatching. Our first set of results, using samples provided by the author, yield recognition rates of over 70% (alphabet) and 90% (26 words), with a confidence of 8%, based solely on acoustic emissions. Our second set of results uses data gathered from nine writers. These results demonstrate that acoustic emissions are a rich source of information, usable - on their own or in conjunction with image-based features - to solve pattern recognition problems. In future work, this approach can be applied to writer identification, handwriting and gesture-based computer input technology, emotion recognition, and temporal analysis of sketches. / Thesis (Master, Computing) -- Queen's University, 2009-09-27 08:56:53.895

Las personas interactúan con su entorno de forma multimodal. Esto es, con el uso simultaneo de sus sentidos. En los últimos años, se ha buscado una interacción multimodal humano-computador desarrollando nuevos dispositivos y usando diferentes canales de comunicación con el fin de brindar una experiencia de usuario interactiva más natural. Este trabajo presenta una herramienta que permite la integración de diferentes tipos de interacción humano computador y probarlo sobre una solución multimodal. / Revisión por pares

There is a strong market demand for enantiomerically pure drugs. One solution to this problem is to develop a simple methodology for transferring synthetically designed racemic drugs into optically pure ones. Many synthetic drugs are by nature amides, therefore, amino acid based models for transformation of racemates into optically pure compounds were selected for this study. Formation of self-assembly molecular aggregates of properly modified amino acids was observed with and without the presence of cyclodextrins. Cyclodextrin assisted formation of polymer-like self-assemblies and enantiomeric resolution of these amino acids were studied using 1D and 2D NMR spectroscopy, EleacroSpray Ionization Mass Spectroscopy (ESIMS), Matrix- Assisted Laser Desorption Ionization Time-of-Flight Mass Spectroscopy (MALDI-TOF-MS). The role of p-p stacking interaction between aromatic moieties in enantiomeric resolution was demonstrated by calculating association constants of this host-guest system. Dolabellane diterpenoids share the unique feature of a trans-bicyclo[9.3.0]tetradecane and most of them express antimicrobial, antitumor and antiviral activities. They are primarily obtained from marine resources. Dolabellane diterpenoid B was isolated from the Okinawan soft coral of the genus Clavularia by Iguchi and co-workers. Current efforts toward the synthesis of dolabellane diterpenoid B is discussed along with the plans for completion of its synthesis.

Thesis advisor: Jorge Garcia / What action or actions does a person perform when she recognizes someone? I argue she engages in a process composed of four parts. First, she attends to the subject in a particular manner. Second, she uses the information gathered in the first stage to categorize the subject. Third, she appreciates the import or significance of the subject in light of the category she employs. Fourth, she acknowledges the subject by engaging the subject’s attention as one who bears that import and that category. My analysis helps us interpret theories of recognition. One clarifies a theory’s specific claims by decomposing theories into instances of recognizing and then further analyzing each instance into discrete actions. First one determines how many instances of the process are involved by stating who does what to whom and for what end. Once instances are separated, one analyses each instance into its four components by describing the agent’s progress through the process of recognizing. The final result is an organizing body of specific claims with well-defined relations to one another. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

archives@tulane.edu / These two studies focused on the development of infants’ functional body knowledge. Many aspects of infant body knowledge have been researched extensively. For example, body parts are mapped onto the somatosensory cortex at least coarsely in infants as young as a few days old or older (Le Cornu Knight, Cowie, & Bremner, 2016; Milh et al., 2007). Infants also have some integration of sensory inputs and motor outputs, as evidenced by their ability to look toward the source of a sound during the first half-year of life (Ashmead, Davis, Whalen, & Odom, 1991; Morrongiello, Fenwick, Hillier, & Chance, 1994). Additionally, infants have some knowledge of body structure, as they can detect discrepancies in the arrangement of the configuration of these body parts and distortions in body part size as early as 3.5 months of age (Zieber, Kangas, Hock, & Bhatt, 2015). Most previous research has focused on nervous system structure, knowledge of body structure, or reactive responses to the environment. Less is known about the development of the agentive response of infants localizing targets on their bodies. In a longitudinal study, vibrating targets were placed on eight different face locations approximately every other week starting as young as 2 months of age to test the development of infants’ ability to reach to targets on the surface of the body. The primary findings were that the ability to reach to targets on the face improved with age, and infants could reach to the mouth earlier than the other face locations. In a second study, these infants then received additional experience with a visual-proprioceptive-tactile contingency in the mirror, which accelerated mirror self-recognition relative to two control group. / 1 / Lisa Chinn
