Liquid Business Process Model Collections

Many organizations realize that increasing amounts of data (“Big Data”) need to be dealt with intelligently in order to compete with other organizations in terms of efficiency, speed and services. The goal is not to collect as much data as possible, but to turn event data into valuable insights that can be used to improve business processes. However, data-oriented analysis approaches fail to relate event data to process models. At the same time, large organizations are generating piles of process models that are disconnected from the real processes and information systems. In this chapter we propose to manage large collections of process models and event data in an integrated manner. Observed and modeled behavior need to be continuously compared and aligned. This results in a “liquid” business process model collection, i.e. a collection of process models that is in sync with the actual organizational behavior. The collection should self-adapt to evolving organizational behavior and incorporate relevant execution data (e.g. process performance and resource utilization) extracted from the logs, thereby allowing insightful reports to be produced from factual organizational data.

Antioxidants in Athlete's Basic Nutrition: Considerations towards a Guideline for the Intake of Vitamin C and Vitamin E

Antioxidants in acute physical exercise and exercise training remain a hot topic in sport nutrition, exercise physiology and biology, in general (Jackson, 2008; Margaritis and Rousseau, 2008; Gomez-Cabrera et al., 2012; Nikolaidis et al., 2012). During the past few decades, antioxidants have received attention predominantly as a nutritional strategy for preventing or minimising detrimental effects of reactive oxygen and nitrogen species (RONS), which are generated during and after strenuous exercise (Jackson, 2008, 2009; Powers and Jackson, 2008). Antioxidant supplementation has become a common practice among athletes as a means to (theoretically) reduce oxidative stress, promote recovery and enhance performance (Peternelj and Coombes, 2011). However, until now, requirements of antioxidant micronutrients and antioxidant compounds for athletes training for and competing in different sport events, including marathon running, triathlon races or team sport events involving repeated sprinting, have not been determined sufficiently (Williams et al., 2006; Margaritis and Rousseau, 2008). Crucially, evidence has been emerging that higher dosages of antioxidants may not necessarily be beneficial in this context, but can also elicit detrimental effects by interfering with performance-enhancing (Gomez-Cabrera et al., 2008) and health-promoting training adaptations (Ristow et al., 2009). As originally postulated in a pioneering study on exercise-induced production of RONS by Davies et al. (1982) in the early 1980s, evidence has been increasing in recent years that RONS are not only damaging agents, but also act as signalling molecules for regulating muscle function (Reid, 2001; Jackson, 2008) and for initiating adaptive responses to exercise (Jackson, 2009; Powers et al., 2010). The recognition that antioxidants could, vice versa, interact with the signalling pathways underlying the responses to acute (and repeated) bouts of exercise has contributed important novel aspects to the continued discussion on antioxidant requirements for athletes. In view of the recent advances in this field, it is the aim of this report to examine the current knowledge of antioxidants, in particular of vitamins C and E, in the basic nutrition of athletes. While overviews on related topics including basic mechanisms of exercise-induced oxidative stress, redox biology, antioxidant defence systems and a summary of studies on antioxidant supplementation during exercise training are provided, this does not mean that this report is comprehensive. Several issues of the expanding and multidisciplinary field of antioxidants and exercise are covered elsewhere in this book and/or in the literature. Exemplarily, the reader is referred to reviews on oxidative stress (Konig et al., 2001; Vollaard et al., 2005; Knez et al., 2006; Powers and Jackson, 2008; Nikolaidis et al., 2012), redox-sensitive signalling and muscle function (Reid, 2001; Vollaard et al., 2005; Jackson, 2008; Ji, 2008; Powers and Jackson, 2008; Powers et al., 2010; Radak et al., 2013) and antioxidant supplementation (Williams et al., 2006; Peake et al., 2007; Peternelj and Coombes, 2011) in the context with exercise. Within the scope of the report, we rather aim to address the question regarding requirements of antioxidants, specifically vitamins C and E, during exercise training, draw conclusions and provide practical implications from the recent research.

An Intelligent Driver Warning System

This chapter is focussed on the research and development of an intelligent driver warning system (IDWS) as a means to improve road safety and driving comfort. Two independent IDWS case studies are presented. The first study examines the methodology and implementation for attentive visual tracking and trajectory estimation for dynamic scene segmentation problems. In the second case study, the concept of driver modelling is evaluated which can be used to provide useful feedback to drivers. In both case studies, the quality of IDWS is largely determined by the modelling capability for estimating multiple vehicle trajectories and modelling driving behaviour. A class of modelling techniques based on neural-fuzzy systems, which exhibits provable learning and modelling capability, is proposed. For complex modelling problems where the curse of dimensionality becomes an issue, a network construction algorithm based on Adaptive Spline Modelling of Observation Data (ASMOD) is also proposed.

Toughness and toughening mechanisms of porous thin films

Toughness is the ability of a material to deform plastically and to absorb energy before fracture. The first of its kind, this book covers the most recent developments in the toughening of hard coatings and the methodologies for measuring the toughness of thin films and coatings. The book looks at the present status of toughness for coatings and discusses high-temperature nanocomposite coatings, porous thin films, laser treated surface layers, cracking resistance, indentation techniques, sliding contact fracture, IPN hybrid composites for protection, and adhesion strength.

Pumping systems: Design and energy efficiency

Pumping systems are widely used in many applications, including municipal water/wastewater services, domestic, commercial and agricultural services, and industrial processes. They are a very significant energy user and consume nearly 20% of the world’s electrical energy demand. Therefore, improving the energy efficiency of pumping systems can provide great benefits in terms of energy, environment, and cost reduction. In this entry, an overview of pump classification with pros and cons of each type of pump is presented. The procedures used to design pumping systems are also outlined. This is then followed by a discussion on the opportunities for improving the energy efficiency of pumping systems during every stage of design, selection, operation, and maintenance.

A bottom-up integration of vision and actions to create cognitive humanoids

In recent years more and more complex humanoid robots have been developed. On the other hand programming these systems has become more difficult. There is a clear need for such robots to be able to adapt and perform certain tasks autonomously, or even learn by themselves how to act. An important issue to tackle is the closing of the sensorimotor loop. Especially when talking about humanoids the tight integration of perception with actions will allow for improved behaviours, embedding adaptation on the lower-level of the system.

Análisis de la contribución de los sistemas silvopastoriles a la conservación de la flora y fauna en tres comunidades de la reserva de biósfera Bosawás

El estudio se realizó en tres comunidades del Territorio Miskitu Indian Tasbaika Kum, Reserva de Biósfera BOSAWAS (Shiminka, Boca de Plis y Esperanza), para describir la interacción entre especies de flora y avifauna y su influencia en la conservación de estas especies en las áreas de pastoreo, a partir de tres criterios: 1) cuantificar flora y avifauna, 2) prácticas de manejo tradicional, 3) estimar beneficios económico generado por sistemas de pastoreo. Se establecieron tres puntos de conteo dentro de transeptos para avifauna, se estableció parcelas para muestreo de la vegetación en cada comunidad, se seleccionó una comunidad beneficiada por subproyectos del Proyecto Corazón (MARENA) y dos áreas clasificadas como bosque secundario. Para evaluar el beneficio económi co se aplicó entrevistas abiertas y estructuradas dirigida a propietarios de ganado, para documentar los principales beneficios tangibles e intangibles que la población obtiene de estos agrosistemas. El análisis de resultados se determinó en base a índices de diversidad, dominancia, equidad y similitud; tomando en cuenta la riqueza, abundancia y densidad de especies. Se encontró que para flora Shiminka obtuvo los mayores valores de dominancia lo que indica que se encuentran especies de mayor importancia, Esperanza tiene mayor equidad y diversidad, en Shiminka y Esperanza se necesitan mayores estudios, el análisis de Clúster arrojó que aunque existe alguna concordancia entre Boca de Plis y Shiminka, las tres difieren entre sí y el mismo resultado se encontró para la avifauna; y para fauna mayor equidad en Shiminka y Esperanza, mientras la más diversa resultó Esperanza. La similitud establece que Boca de Plis y Esperanza necesitan mayor intensidad de muestreo.

Nemátodos fitoparásitos en palma africana Elaeis guineensis (Jacq) y cocotero Cocos nucifera L. en el Atlántico Sur, Nicaragua

Este estudio se llevó a cabo en plantaciones de Palma africana y cocotero de las regiones de Río San Juan y en la Región Autónoma del Atlántico Sur (R.A.A.S), con el objetivo de identificar nematodos asociados en ambos cultivos, contribuir a la actualización del listado nacional de nemátodos y determinar las infestación de Rhadinaphelencus cocophilus Cobb. en picudos (Rhynchophorus palmarum L.) de la palma y el cocotero Este trabajo se realizó en dos etapas; la primera consistió de dos muestreos (uno por región) y la última etapa fue de procesamiento y análisis de muestras. El primer muestreo se realizó en los lotes de las cooperativas Luisa A. Espinoza, El Borbollón y Teodoro Martinez en Kukra Hill para la palma africana y en coco se muestreo un lote del INTA, posteriormente se muestrearon las fincas; San Nicolás y San Mariano, luego se realizó un segundo muestreo en palma africana en el lote de la cooperativa Luisa A. Espinoza en Boca de Sábalos, Rio San Juan. La segunda etapa consistió en el análisis de las muestras; el cual se realizó inmediatamente después del muestreo. Se identificaron los géneros; Rotylenchulus, Trichodorus, Psilenchus, Aphe/enchoides, Paratylenchus, He/icotylenchus, Tylenchus, Xiphinema y Meloidogyne en el cultivo de palma africana y en cocotero se lograron identificar los siguientes géneros; Psílenchus, Aphelenchoides, Paratylenchus, Pratylenchus, Helicoty/enchus, Ty/enchus, Xiphinema y Rhadinaphelenchus. Para el cultivo de la palma africana, los géneros; Roty/enchus, Gracilacus, Psilenchus, Aphelenchoides, Paratylenchus y Meloidogyne fueron reportados por primera vez por lo que deberán ser agregados al listado nacional de plagas del MAG­FOR de la misma manera para el cultivo de coco, con los géneros; Aphelenchoides, Paratylenchus y Psilenchus. En los muestreos realizados en palma africana y coco en las localidades de Boca de Sábalos y en Kukra Hill se encontró la presencia de Rhynchophorus palmarum Linnaeus. En las fincas "San Nicolás" y "San Mariano", mas del 50 por ciento de los insectos (Rhynchophorus pa/marum Linnaeus) se encontraron infestados con el género Rhadinaphelenchus.

Recently discovered Iron Age lion figurines from Jerusalem

Abstract: More than 500 Iron Age figurines were discovered in the 2005–2010 Western Wall Plaza excavations in Jerusalem.1 The excavations revealed a large building, probably of the four-room type. Many figurines were discovered in this building, others in fills below and above it, dating in general to the eighth-sixth centuries BCE. Here we focus on two heads most likely depicting lions, one of them exceptional—holding another animal in its mouth. We discuss the identification of these figurines as lions, the lion motif in a variety of media in the Southern Levant, and finally recent theories concerning lions in the Hebrew Bible and their relation to Yahweh. We suggest that the two Western Wall Plaza figurines represent lions as wild animals, in similarity to other figurines of wild animals made on occasion by Judean coroplasts.

Entrevista a Simón Imperiale : su “Cuarteto Litúrgico”

Simón Imperiale resume su vida en las siguientes líneas: “Nací el 16 de julio de 1920 en el barrio de La Boca, Buenos Aires. Soy el mayor de cinco hermanos. Estudié Bachillerato Clásico: Latín, Griego, Filosofía y Teología. Mi afición al arte, la poesía, la literatura Universal y a la música, despertaron tempranamente. Creo oportuno destacar que, como durante mi infancia y juventud no pude abordar estudios formales en música y composición, soy, pues autodidacta. A parte de componer, también me dediqué al piano y al órgano. De hecho, me desempeñé como organista en la Parroquia de la Piedad durante diez años y luego fui organista de la Parroquia de San Cayetano durante cuarenta y seis años (hace unos años participé en un Documental sobre la vida de San Cayetano, filmado en la Argentina y en Italia). Actualmente tengo noventa y un años. Aún sigo escribiendo; ya no me dedico tanto a la composición musical, pero sí a la prosa y a la poesía. Tengo un hijo, Marcelo, y dos nietos: Fiorela (9 años) y José (7 años).”

Diversidad de aves en ocho comunidades del territorio Miskitu Indian Tasbaisca Kum, Reserva de Biósfera Bosawás, Nicaragua

La introducción de ganado en las áreas tradicionalmente agrícolas en el territorio Miskitu Indian Tasbaiska Kum ha influido en una modificación en su orden territorial para dar cabida a éste nuevo rubro por parte de sus habitantes. Es comúnmente conocido que la ganadería es una de las actividades productivas más incompatiblescon el bosque y la conservación de los elementos dentro de éste último, pero la rotación de las áreas de cultivo y pastoreo, y el uso de sistemas silvopastoriles podría reducir el impacto hacia los ambientes naturales. Con este estudio se plantea determinar la diversidad biológica de avifauna en los sistemas silvopastoriles ubicados en las cercanías de ocho comunidades del territorio Miskitu Indian Tasbaiska Kum, con el fin de determinar su potencial para preservar aves, en especial, aves de importancia para la conservación nacional. Para lograr los objetivos se realizó conteos de aves mediante el uso de puntos de conteo por comunidad, en las áreas donde suele llevarse a pastorear al ganado. En el estudio se invirtieron tres días por comunidad y se realizaron al menos dos observaciones por día, una entre las 06:00-10:00 y otra entre las 16:00 – 18:00. Con los datos obtenidos se calculó diferentes parámetros de diversidad biológica. Como resultado se observó un total de 423 individuos los cuales están agrupados en 67 especies y 27 familias. Las especies de aves más abundantes fueron: Brotogeris jugularis,Ramphocelus passerinii y Amazona auropaliata. Las comunidades Amarrana,Shiminka y Yakalpanani son las que registraron los mayores valores de los parámetros de biodiversidad. Se determinaron 14 especies en algún grado de conservación según la lista de los apéndices de CITES para Nicaragua y las listas del Sistema Nacional de Vedas 2012, entre éstas se incluyen Brotogeris jugularis y Amazona aurapaliata,as cuales resultaron también abundantes. La comunidad que concentró la mayor cantidad de aves en algún estado de con servación fue Yakalpanani. Las especies de plantas asociadas con la mayor diversidad de aves fueron especies de estadíos tempranos de sucesión como:Cecropia peltata ,Inga sp, Guazuma ulmifolia y Muntingia calabura. Aunque Yakalpanani es una de las comunidades más grandes, comparado con Boca de Plis, la ubicación de su área de pastoreo entre masas boscosas conservadas ha garantizado que los parámetros de diversidad biológica hayan resultado significativamente mayores en ésta, dado a una conectividad hasta el momento poco irrumpida.

Cracks in saturated sand

The formation mechanism of water film (or crack) in saturated sand is analyzed numerically It is shown that there will be no stable "water film" in the saturated sand even if the strength of the skeleton is zero and no positions are choked. The stable water films initiate and grow if the choking state keeps unchangeable once the fluid velocities of one position decreases to zero in a liquefied sand column. A simplified method for evaluating the thickness of water film is presented according to a solidification wave theory. The theoretical results obtained by the simplified method are compared with the numerical results and the experimental results of Kokusho.
