Emotions and the Engineering of Adaptiveness in Complex Systems

A major challenge in the engineering of complex and critical systems is the management of change, both in the system and in its operational environment. Due to the growing of complexity in systems, new approaches on autonomy must be able to detect critical changes and avoid their progress towards undesirable states. We are searching for methods to build systems that can tune the adaptability protocols. New mechanisms that use system-wellness requirements to reduce the influence of the outer domain and transfer the control of uncertainly to the inner one. Under the view of cognitive systems, biological emotions suggests a strategy to configure value-based systems to use semantic self-representations of the state. A method inspired by emotion theories to causally connect to the inner domain of the system and its objectives of wellness, focusing on dynamically adapting the system to avoid the progress of critical states. This method shall endow the system with a transversal mechanism to monitor its inner processes, detecting critical states and managing its adaptivity in order to maintain the wellness goals. The paper describes the current vision produced by this work-in-progress.

Arquitectura industrial tabacalera en la España peninsular: secaderos y fábricas

La Arquitectura industrial del tabaco en España está representada por dos tipos de construcciones, que corresponden a las dos fases en las que se divide el proceso de producción del tabaco: los secaderos (arquitectura bioclimática donde se realiza el secado), y las fábricas (centros donde se elabora el tabaco procedente de los secaderos). Las fábricas se repartieron por todo el territorio español, ocupando preferiblemente los lugares costeros, aunque existen casos en los que su localización obedecía a razones políticas. Estos edificios, en su mayoría, incluidos en los centros históricos de las ciudades, han cambiando de uso, y las antiguas fábricas de tabaco se han transformado en su mayoría, en centros de cultura, o centros sociales y representativos. La tesis surge del análisis de las características constructivas de la arquitectura industrial del tabaco: de los secaderos y de las fábricas, por tratarse de una tipología con suficiente entidad y un ejemplo de arquitectura bioclimática de producción en el caso de los secaderos, y por conseguir haberse adaptado a otros usos en el caso de las fábricas. La arquitectura de producción emplea un lenguaje acorde con los avances de la industrialización, anticipando materiales y estructuras, y condensando en una tipología específica las complejas relaciones establecidas entre producto, hombres y espacio. Estos edificios tuvieron una extensa implantación en el territorio, y se caracterizan por una serie de valores tecnológicos, arquitectónicos, sociológicos y paisajísticos, que hacen de ellos un documento de primera magnitud para conocer: la evolución e implantación de las técnicas constructivas (materiales y estructuras), los procesos de innovación tipológica y la estructura económica y procedimientos técnicos utilizados. El territorio en el que se insertan constituye su contexto territorial, por lo que no sería adecuado considerar estos edificios como elementos aislados, sin analizar la relación con el entorno en el que se generaron. Por este motivo, se analizan las condiciones higrotérmicas ambientales de los secaderos para compararlas con las de confort humano y establecer relaciones y parámetros compatibles. Los ejemplos analizados de secaderos son todos de fábrica. El uso del ladrillo como módulo principal para la elaboración de un edificio, supone la consideración de un “grado cero” de todo el aparato constructivo y compositivo de la arquitectura. Dejar el ladrillo visto, supone hacer explícitos todos los procesos acumulativos. Este elemento mínimo, permite unas posibilidades enormemente abiertas, pero no absolutamente aleatorias, que definen su propia lógica combinatoria. La exigencia de sinceridad, característica de la arquitectura industrial, en la exposición de los materiales, exhibiéndolos en su propia naturaleza y en el modo real de ser utilizados, se hace patente en este tipo de construcción. Se realiza un estudio de permeabilidad en las fachadas de los secaderos, para determinar el grado de ventilación y su relación con la orientación, el patrón de celosía empleado y el volumen total. Este sistema de acondicionamiento climático específico, puede servir de recurso a otras construcciones, por lo que se podría trasladar el sistema constructivo y formal de los secaderos a otros usos, desde una doble vertiente: Arquitectura para la adaptación climática al entorno. Arquitectura como generadora de condiciones climáticas específicas, en el interior. La utilidad de los secaderos es fundamentalmente: proporcionar sombra, ventilación y un espacio cubierto, pero permeable en sus fachadas. La arquitectura industrial debe ser reconocida dentro del conjunto patrimonial, debido a sus características propias que permiten su diferenciación del resto de la arquitectura. Conocer la estructura productiva permite analizar correctamente estas construcciones, ya que el programa inicial es básico para entender la organización del espacio interior. Las fábricas no se situaron cerca de las zonas de producción del tabaco, excepto en dos casos: Cádiz y Palazuelo, en los que existen secaderos y campos de cultivo de hoja de tabaco en las áreas cercanas. La principal causa de esta separación es que el proceso de obtención de tabaco es un proceso dividido en dos fases principales: proceso primario y proceso secundario. En el proceso primario la hoja de tabaco se seca en los secaderos, en los que es determinante el clima, pero únicamente en el caso del secado del tabaco al aire. En el proceso secundario sin embargo, el tabaco llega previamente tratado a las fábricas, por lo que no influye el clima en esta parte del proceso. Esta razón determina que en las áreas climáticas donde se centra el estudio, haya zonas en las que existen fábrica y secaderos y otras en las que únicamente existe fábrica, o sólo secaderos. La localización de las fábricas atendía a razones de muy diferente índole, las más importantes fueron: geográficas, estratégicas, y políticas. En la mayoría de las fábricas la elección de la ciudad de emplazamiento estaba ligada a la recepción de la materia prima, que principalmente se hacía por vía marítima, o acuática (el caso de Sevilla), y por vía terrestre, utilizando como medio de transporte el ferrocarril. Sólo dos casos, de las antiguas fábricas, corresponden a razones políticas, son las dos únicas que no están en la costa: Madrid y Logroño. La de Madrid se construyó por centralidad política, y porque geográficamente ocupaba el punto central de todas las comunicaciones terrestres por carretera y ferrocarril. Muchas de las fábricas se situaron cercanas a las estaciones de ferrocarril. La de Logroño atendió, sin embargo, a razones políticas. Para finalizar, se realiza un estudio comparativo de las fábricas de Sevilla, Madrid y San Sebastián. Las razones que justifican esta elección son: - La de Sevilla fue históricamente la primera fábrica y la más importante. - La de Madrid fue la más importante a nivel administrativo, la sede de Tabacalera se instaló en la capital, y después de la de Sevilla, fue la que sirvió de modelo al resto de las fábricas. - La de San Sebastián era la más grande del Norte. Los análisis que se han realizado son de: volumen y superficies de patios, superficies de cubierta, permeabilidad o huecos en fachadas, orientación y soleamiento de patios, distribución espacial interior y organización, y evolución de usos. Podemos observar que en la mayoría de estas fábricas ha habido una transformación en el uso, pasando de ser edificios industriales a edificios culturales. Estas construcciones se pueden considerar como infraestructuras adaptables, por ser útiles, sostenibles y funcionales. ABSTRACT The Spanish industrial architecture of tobacco is represented by two construction types that correspond to the two phases of tobacco production: the drying sheds (bioclimatic constructions where the drying process takes place) and factories (centres where tobacco is processed after the drying process). The factories were distributed throughout the Spanish territory, preferably occupying coastal locations, although some of them were located elsewhere following political reasons. Most of the buildings inside city centres have suffered changes in their use, becoming cultural, social or representative centres. This thesis attempts the analysis of the constructive systems employed in tobacco industrial architecture, from drying sheds to factories. The drying sheds are an example of bioclimatic industrial architecture. The factories are a typology that have successfully adapted to new uses. Industrial architecture uses a language that follows the advances in industrialization, anticipating new materials and structures, and merging the complex relationships established among products, human beings, space and locations. These buildings were promoted extensively in the country. They are characterized by technological architectural sociological and landscaping innovations. They are considered as important examples of the evolution and the implementation of construction techniques (building materials and structures). They are also considered as examples of innovation in the building typology, in their economic structure and in the technologies that they have applied. The settings in which the drying sheds are placed have an important influence in them. They cannot be considered as isolated elements. Instead, there is a close relationship between drying sheds and the surroundings in which they are located. Drying sheds’ hygrotermal and environmental conditions are analyzed in this thesis to compare them with the values of human comfort and find suitable relationships and parameters. All the drying sheds that have been analyzed are constructed with brick. This implies a consideration of “zero degree” for both the construction and the composition of the architectural process. The detailing - entails making all the accumulative processes explicit as the brick walls are left exposed. This minimal component allows a wide range of options that are never random but based on the logic of the way in which it is combined. The “sincerity” in the exposition of material, displaying them in their very nature and showing how they are really used, is a basic characteristic of industrial architecture, and it is even more expressive in these types of buildings. The walls of the drying sheds undergo a permeability assessment in order to determine the degree of ventilation and orientation, the lattice pattern used and the overall volume. This specific conditioning system can serve as a resource for other buildings, and consequently, it could be transferred to other uses within a two-pronged approach: -Climatically adapted architecture that takes into account the surroundings. -Architecture as a generator of specific climatic conditions indoors. Drying sheds’ main purposes / aims deal with how to provide shade, ventilation and a covered space as well as permeability. The industrial architecture must be recognized as historical valuable buildings due to its intrinsic and distinctive characteristics. Knowing the productive structure, allow us to make a proper analysis of these buildings, since the basic aim, is to understand the spatial organization indoors. Factories did not come close to the tobacco production, with the exception of Cádiz and Palazuelo, where there are sheds and tobacco croplands nearby. The main reason for this separation is that the process of obtaining tobacco has two processes: the primary process and the secondary process. In the primary process tobacco leaves are left to dry. In the secondary process, previously manufactured tobacco allocated in the factories where the weather conditions are not important. This fact determines that in the climate areas where this study tales place there are some cases in which we can find both factories and drying sheds, and others where there are either factories or drying sheds only. The location of these factories met various demands, being the most outstanding the ones related to geographic, strategic and political reasons. In most factories the choice of its location was often linked to the incoming of raw goods, mainly delivered through waterways –it is the case of Seville,) and by land, using railways. The location of the factories was linked to political reasons in only two cases Madrid and Logroño, which are the only ones that are not placed near the coast. The one in Madrid was built due to its political centrality and because geographically speaking, it was the reference landmark of means of land and rail transports. Many factories, in fact, were settled nearby rail stations. For the factory in Logroño, only political reasons were taken into consideration. I should like to close by undertaking a comparative study of factories in Seville, Madrid and San Sebastian. There are a number of reasons to substantiate this choice: -The factory in Seville was historically speaking the first that was built and the most important one. -The factory in Madrid was the most important one administratively. This factory was the headquarters as well as being, after Seville, the one which provided a model for other factories. -The factory in San Sebastian is the biggest in the North of Spain. The analysis carried out are related to the volume of the buildings and the surface areas of the courtyards, the surface of the roofs, the permeability of the walls and the openings of the façade, the orientation and the sun exposure, the indoor spatial distribution and organization and evolution of the uses (formerly and currently) I observe that in most of these factories there has been a change in the use of the buildings, from industrial cultural purposes. These buildings can be considered as adaptable infrastructures based on a combination of architectural practicability, sustainability and functionality.

NEMAWASHI: Attaining Value Stream alignment within Complex Organizational Networks

In the process of value creation, organizations perform an intense intra-organizational dialog through which internal VS alignment is achieved towards certain strategic objectives. Within the context of complex organizational networks, were goal conflicts are preprogrammed through incentive structures, VS alignment as legitimation of action towards strategic goals has special interest. On the one hand it facilitates the access to necessary resources for goal achievement and on the other it increases the sustainability and supports commonly agreed upon decisions leading to success. This paper provides a winnerless process (WLP) differential equations model for quantifying intra-organizational value stream (VS) alignment dynamics that can help design sustainable lean management solutions. This paper presents ongoing research results that show how the model was implemented in one industrial facility.

Kinetic characterization of brush border myosin-I ATPase

Brush border myosin-I (BBM-I) is a single-headed unconventional myosin found in the microvilli of intestinal epithelial cells. We used stopped-flow kinetic analysis to measure the rate and equilibrium constants for several steps in the BBM-I ATPase cycle. We determined the rates for ATP binding to BBM-I and brush border actomyosin-I (actoBBM-I), the rate of actoBBM-I dissociation by ATP, and the rates for the steps in ADP dissociation from actoBBM-I. The rate and equilibrium constants for several of the steps in the actoBBM-I ATPase are significantly different from those of other members of the myosin superfamily. Most notably, dissociation of the actoBBM-I complex by ATP and release of ADP from actoBBM-I are both very slow. The slow rates of these steps may play a role in lengthening the time spent in force-generating states and in limiting the maximal rate of BBM-I motility. In addition, release of ADP from the actoBBM-I complex occurs in at least two steps. This study provides evidence for a member of the myosin superfamily with markedly divergent kinetic behavior.

The episcopal complex of Eio-El Tolmo de Minateda (Hellín, Albacete, Spain). Architecture and spatial organization. 7th to 8th centuries AD

The episcopal complex of Eio, located in El Tolmo de Minateda, was built between the end of the 6th century and the beginning of the 7th century, possibly as a political decision taken by the ecclesiastical authority in the capital of the Visigothic kingdom (Toletum). With the comprehensive study of the whole complex presented below (construction cycles, furniture, decoration and location of spaces), we can interpret the function of each space in the basilica and the domus episcopi, the liturgical and general movement routes, the existence of some hierarchical environments, and specify the chronological development of the buildings. After the Arab-Berber conquest of Hispania in the early 8th century, the whole complex will experience a series of transformations that will convert the religious and monumental public area into a private, residential and industrial Islamic quarter.

Rigorous Design of Complex Distillation Columns Using Process Simulators and the Particle Swarm Optimization Algorithm

We present a derivative-free optimization algorithm coupled with a chemical process simulator for the optimal design of individual and complex distillation processes using a rigorous tray-by-tray model. The proposed approach serves as an alternative tool to the various models based on nonlinear programming (NLP) or mixed-integer nonlinear programming (MINLP) . This is accomplished by combining the advantages of using a commercial process simulator (Aspen Hysys), including especially suited numerical methods developed for the convergence of distillation columns, with the benefits of the particle swarm optimization (PSO) metaheuristic algorithm, which does not require gradient information and has the ability to escape from local optima. Our method inherits the superstructure developed in Yeomans, H.; Grossmann, I. E.Optimal design of complex distillation columns using rigorous tray-by-tray disjunctive programming models. Ind. Eng. Chem. Res.2000, 39 (11), 4326–4335, in which the nonexisting trays are considered as simple bypasses of liquid and vapor flows. The implemented tool provides the optimal configuration of distillation column systems, which includes continuous and discrete variables, through the minimization of the total annual cost (TAC). The robustness and flexibility of the method is proven through the successful design and synthesis of three distillation systems of increasing complexity.

Footwear bio-modelling: An industrial approach

There is a growing need within the footwear sector to customise the design of the last from which a specific footwear style is to be produced. This customisation is necessary for user comfort and health reasons, as the user needs to wear a suitable shoe. For this purpose, a relationship must be established between the user foot and the last with which the style will be made; up until now, no model has existed that integrates both elements. On the one hand, traditional customised footwear manufacturing techniques are based on purely artisanal procedures which make the process arduous and complex; on the other hand, geometric models proposed by different authors present the impossibility of implementing them in an industrial environment with limited resources for the acquisition of morphometric and structural data for the foot, apart from the fact that they do not prove to be sufficiently accurate given the non-similarity of the foot and last. In this paper, two interrelated geometric models are defined, the first, a bio-deformable foot model and the second, a deformable last model. The experiments completed show the goodness of the model, with it obtaining satisfactory results in terms of comfort, efficiency and precision, which make it viable for use in the sector.

The Eastern external border of the enlarge European Union. Cross-border co-operation at the new Eastern border of the European Union. Russian-speakers in Latvia and Estonia. OSW Study 14/2004

Russians or so-called Russian-speakers in Latvia and Estonia pose a significant problem for both countries. Russian-speakers are a numerous minority in Latvia and Estonia, which causes deep division in these countries from the ethnical point of view. The problem of highest importance in the legal aspect is the unregulated status of the Russian-speakers. Though they are permanent residents of Latvia and Estonia many of them still do not have these countries' citizenship. The complex naturalisation procedure introduced by Latvia and Estonia soon after restoring independence in 1991 is considered to be main responsible for this.

Robust multivariable control of complex biological processes

This paper addresses advanced control of a biological nutrient removal (BNR) activated sludge process. Based on a previously validated distributed parameter model of the BNR activated sludge process, we present robust multivariable controller designs for the process, involving loop shaping of plant model, robust stability and performance analyses. Results from three design case studies showed that a multivariable controller with stability margins of 0.163, 0.492 and 1.062 measured by the normalised coprime factor, multiplicative and additive uncertainties respectively give the best results for meeting performance robustness specifications. The controller robustly stabilises effluent nutrients in the presence of uncertainties with the behaviour of phosphorus accumulating organisms as well as to effectively attenuate major disturbances introduced as step changes. This study also shows that, performance of the multivariable robust controller is superior to multi-loops SISO PI controllers for regulating the BNR activated sludge process in terms of robust stability and performance and controlling the process using inlet feed flowrate is infeasible.

Resolving the organization of the New World monkey third visual complex: The dorsal extrastriate cortex of the marmoset (Callithrix jacchus)

We tested current hypotheses on the functional organization of the third visual complex, a particularly controversial region of the primate extrastriate cortex. In anatomical experiments, injections of retrograde tracers were placed in the dorsal cortex immediately rostral to the second visual area (V2) of New World monkeys (Callithrix jacchus), revealing the topography of interconnections between the third tier cortex and the primary visual area (V1). The data indicate the presence of a dorsomedial area (DM), which represents the entire upper and lower quadrants of the visual field, and which receives strong, topographically organized projections from the superficial layers of V1. The visuotopic organization and boundaries of DM were confirmed by electrophysiological recordings in the same animals and by architectural characteristics which were distinct from those found in ventral extrastriate cortex rostral to V2. There was no electrophysiological or histological evidence for a transitional area between V2 and DM. In particular, the central representation of the upper quadrant in DM was directly adjacent to the representation of the horizontal meridian that marks the rostral border of V2. The present results argue in favor of the hypothesis that the third visual complex in New World monkeys contains different areas in its dorsal and ventral components: area DM, near the dorsal midline, and a homolog of area 19 of other mammals, located more lateral and ventrally. The characteristics of DM suggest that it may correspond to visual area 6 (V6) of Old World monkeys. (C) 2005 Wiley-Liss, Inc.

Using the floatability characterisation test rig for industrial flotation plant design

Industrial flotation plant design is a complex process involving many aspects, one of which is the use of pilot-scale plants to test industrial plant flow sheets. Once test work on a pilot-scale has been performed, scale-up of these results to the full-scale plant must be performed. This paper describes scale-up test work performed on the Floatability Characterisation Test Rig (FCTR). The FCTR is a self-contained, highly instrumented mobile pilot plant designed to determine flotation model parameters and to develop and validate flotation plant modelling, scale-up and simulation methodologies.
