An integrated system for human action recognition from video using hidden Markov model

In this paper, we present an integrated system for real-time automatic detection of human actions from video. The proposed approach uses the boundary of humans as the main feature for recognizing actions. Background subtraction is performed using Gaussian mixture model. Then, features are extracted from silhouettes and Vector Quantization is used to map features into symbols (bag of words approach). Finally, actions are detected using the Hidden Markov Model. The proposed system was validated using a newly collected real- world dataset. The obtained results show that the system is capable of achieving robust human detection, in both indoor and outdoor environments. Moreover, promising classification results were achieved when detecting two basic human actions: walking and sitting.

Antifungal action of three (Z)-5-amino-N'-aryl-1-methyl-1H-imidazole-4-carbohydrazonamides

[Excerpt] The incidence of fungal infections has greatly increased in patients under sustained immunosuppression with considerable risk associated. Difficulties regarding prompt diagnosis and the limited therapeutic options dictate high mortality rates. Available antifungals display substantial toxicity, a predictable consequence of the cellular structure of the organisms involved, reduced spectrum of activity, and drug interactions. Our group had previously identified three (Z)-5-amino-N'-aryl-1-methyl-1H-imidazole-4-carbohydrazonamides 1 [aryl= phenyl (1a), 4-fluorophenyl (1b), 3fluorophenyl (1c)] as potent antifungal agents.1 (...)

COST Action TU1406: eBook of the 1st Workshop Meeting

COST Action TU1406 aims to address the European economic and societal needs by standardizing the condition assessment and maintenance level of roadway bridges. Currently, bridge quality control plans vary from country to country and, in some cases, within the same country. This therefore urges the establishment of a European guideline to surpass the lack of a standard methodology to assess bridge condition and to define quality control plans for roadway bridges. Such a guideline will comprise specific recommendations for assessing performance indicators as well as for the definition of performance goals, bringing together different stakeholders (e.g. universities, institutes, operators, consultants and owners) from various scientific disciplines (e.g. on-site testing, visual inspection, structural engineering, sustainability, etc.) in order to establish a common transnational language. COST Action TU1406 Workshops aim to facilitate the exchange of ideas and experiences between active researchers and practitioners as well as to stimulate discussions on new and emerging issues in line with the conference topics. This first Workshop essentially focuses on WG1 issues, namely, intends to address performance indicators, how these are assessed (e.g. visual inspection, nondestructive tests and monitoring systems), with what frequency and what values are generally obtained. The main outcomes, given in this eBook, were really important, not only for WG1 developments, but also for all the other WGs and for the Action itself.

Democracia Deliberativa en Córdoba: análisis de los alcances y limitaciones de algunas experiencias participativas, contribuciones para su factibilidad. Deliberative Democracy in Córdoba: scope and limitations of participatory experiences.

En el debate académico y social los críticos de la democracia deliberativa coinciden en sostener la imposibilidad de realización de este ideal, fundamentando dicha afirmación en hechos sociales relevantes como el pluralismo, la desigualdad, la complejidad, poderosas instituciones y una esfera pública polarizada en extremo. En atención a las mencionadas críticas algunos autores han destacado que la viabilidad de una forma deliberativa de democracia depende de la creación de condiciones sociales y arreglos institucionales que propicien el uso público de la razón. La deliberación es pública en la medida en que estos arreglos permitan el diálogo abierto entre ciudadanos capaces de formular juicios informados y razonados en torno a las formas de resolver situaciones problemáticas. La factibilidad y eficacia de la deliberación pública reside, a su vez, en la posibilidad de sostener no sólo un diálogo abierto y continuo entre ciudadanos, sino también de éstos con las instituciones políticas. En esta discusión se inserta el presente proyecto con el fin de estudiar los problemas de justificación e institucionalización, como así también los obstáculos y constreñimientos empíricos con los que se enfrenta la democracia deliberativa. Para ello se toman diversas experiencias en la Provincia de Córdoba: El Acta de Compromiso Público de la Ciudad de Córdoba, Los Observatorios de Servicios Públicos de la Asociación Civil el Ágora, Concertación en Espacios Locales de la Asociación Civil el Ágora y las Juntas de Participación Vecinal de la Municipalidad de Córdoba. Todos estos procesos se caracterizan por constituir iniciativas que procuran la creación, fortalecimiento e institucionalización de espacios de participación ciudadana y de interacción dialógica de los ciudadanos entre sí y de éstos con el estado. Estos espacios son espacios situados y, en cuanto tales, implican contigencias devenidas de las particularidades territoriales, temáticas y de los diferentes horizontes temporales sobre los que se proponen actuar. El proyecto se propone analizar los alcances y dificultades (políticas, sociales, organizativas, informacionales) que se presentan en estas experiencias deliberativas, atendiendo tanto a los requisitos de factibilidad de las propias experiencias como a la necesidad de fortalecer los planteamientos teóricos de la teoría de la deliberación pública a partir de la consideración de los problemas empíricos con los que la misma se enfrenta. Se prevé el desarrollo e implementación de indicadores de seguimiento y monitoreo de las experiencias que den cuenta de las dimensiones y presupuestos de la democracia deliberativa, la construcción de modelos procedimentales y tecnologías comunicativas que contribuyan a la factibilidad de los presupuestos comunicativos y la contribuición al desarrollo de proposiciones teóricas vinculadas con la preocupación académica referida a los procesos deliberativos y participativos en las sociedades contemporáneas.

Action of growth regulators on flowering and pod production of soybean cultivar Davis

This research deals with the effects of growth regulators on flowering and pod formation in soybean plant (Glycine max cv. Davis). Under greenhouse conditions, soybean plants were sprayed with 2,3,5-triiodobenzoic acid (TIBA) 20 ppm, Agrostemmin (1g/10 ml/3 l) gibberellic acid (GA) 100 ppm, and (2-chloroethyl) trimethylammonium chloride (CCC) 2,000 ppm. Application of TIBA increased number of flowers. 'Davis' soybean treated with CCC and TIBA presented a tendency to produce a lower number of pods.

Action of growth regulators on production of soybean cultivar Davis

This research deals with the effects of exogenous growth regulators on production of soybean plant (Glycine max cv.. Davis) under greenhouse conditions, At the flower anthesis, 2,3,5-triiodobenzoic acid (TIBA) 20 ppm was applied. Other two applications with TiBA, with intervals of four days, were realized. Before flowering, Agrostemin (1 g/10 ml/3 1), gibberellic acid (GA) 100 ppm, and (2-chloroethyl) trimethylammonium chloride (CCC) 2,000 ppm were applied. It was observed that CCC and TIBA reduced stem dry weight. Soybean plants treated with TIBA reduced weight of pods without seeds , seed number and seed weight.
