Abstract:
La productivité de la morelle noire est faible sur les sols surexploités dans les zones périurbaines de Brazzaville. L’objectif était d’évaluer l’apport de la terre des termitières sur la croissance végétale de trois cultivars de la morelle noire. Les termitières collectées ont été broyées, tamisées et amendées les planches de 3 m x 1,2 m. Une planche ayant reçu 0 kg, 2 kg, 4 kg et 6 kg de terre des termitières, 60 plants d’un cultivar ont été repiqués aux écartements 20 x 20 cm selon un schéma bi factoriel complet 4 x 3 logé dans un dispositif en bloc complètement randomisé. Les traitements ont été répétés trois fois. Les résultats ont révélé une meilleure croissance en hauteur et en diamètre ainsi qu’un meilleur développement foliaire des plants amendés avec les doses de la terre des termitières en comparaison de ceux n’en ayant pas reçu. L’apport de 6 kg de terre des termitières montre une influence positive sur le développement racinaire de plants des trois cultivars. L’apport 2 kg, 4 kg et 6 kg de terre de termitières améliore la croissance végétative et le rendement en biomasses aérienne et souterraine de trois cultivars de morelle noire cultivés au Congo. © 2020 International Formulae Group.

English Title: Effect of the termite mounds on the vegetative production of three cultivars of black nightshade (Solanum nigrum L.: Solanaceae) grown in Brazzaville, Congo English Abstract The productivity of black nightshade is low on the overexploited soils in the suburban areas of Brazzaville. The objective was to evaluate the contribution of termite mound on the plant growth of three black nightshade cultivars. The termite mounds were collected, crushed, sieved and amended the planks of 3m x 1.2m. A board having received 0 kg, 2 kg, 4 kg and 6 kg of termite mounds, 60 plants of a cultivar were transplanted at 20 x 20 cm intervals according to a complete 4 x 3 bi-factorial diagram housed in a block plan completely randomized. The treatments were repeated three times. The results showed better growth in height and diameter, as well as better foliar development of seedlings amended with termite mounds compared to those that did not. The contribution of 6 kg of termite mound had a positive influence on the root development of the three cultivars. The contribution of 2 kg, 4 kg and 6 kg of termite mound improved vegetative growth and yield in aboveground and belowground biomass of three black nightshade cultivars grown in Congo. © 2020 International Formulae Group.

Abstract:
This paper addresses the task to devise a statistical estimation procedure in an event where the volume of the array of initial data used in processing is insufficient to correctly determine the parameters of the response function. The object of research is the technology of statistical processing of a small sample of data. The subject of the study is the methods of statistical estimation under conditions of a small sample of initial data. The main direction is to devise a special procedure for statistical processing of a small sample of initial data, which provides a correct statistical estimation of the parameters of the response function. The method for solving the problem is the selection of the most representative orthogonal replica-like subplan from the plan of a complete factorial experiment obtained by artificially orthogonalizing the results of a passive experiment. The necessity and expediency of the proposed procedure is a consequence of the unpredictability and uneven distribution of points in the phase space of coordinates. The result of the implementation of the corresponding procedure is a truncated orthogonal plan of the full factorial experiment, which provides the possibility of independent estimation of all coefficients of the regression polynomial describing the response function. Under conditions of a severe shortage of the number of measurements, the procedure makes it possible to isolate a representative orthogonal replica from the resulting plan of a complete factorial experiment. Using this subplan of the full factorial experiment plan makes it possible to evaluate all the coefficients of the regression polynomial that describes the desired response function. The corresponding computational procedure is based on solving the triaxial Boolean assignment problem

Abstract:
The Kashima petrochemical complex and the Fukashiba industrial wastewater treatment plant are described. The complex consists of 19 core factories (petroleum, petrochemicals, and thermal power generation) and 39 other factories (including organic chemicals, foods, metals, machinery, etc.). The total amount of industrial wastewater produced is 59,800 m3/day. The treatment plant also accepts municipal wastewater from the surrounding area, totalling 1,100 m3/d. A system for charging for the industrial wastewater has been introduced. The water quality standards for the industrial wastewater discharged to the sewerage system and the effluent of the treatment plant are described. The main treatment process is activated sludge with operational conditions of high dissolved oxygen and long solids retention time (SRT). These operational conditions solved the problems of high ammonia and refractory substances in the influent. Complete nitrification occurred under the low alkalinity conditions and the effluent COD was low due to the long SRT. Successful operation and maintenance were achieved by good co-operation between the factories and the treatment plant.

Abstract:
Semiconductor factories are significantly affected by the spray pattern of ceiling sprinkler heads owing to the large scale and complex mix of organic/exhaust ducts and multiple pipes. Therefore, sprinkler heads are installed in the spray disorder section of the lower barrier. However, more efficient installation measures are needed to mitigate the absence of detailed installation standards and interference with human and equipment transport lines. Currently, installation causes major confusion at construction sites and increases construction costs. The purpose of this research is to overcome these challenges by evaluating the operation status of sprinkler facilities in semiconductor factories, identify problems, and suggest more efficient installation measures. An installation plan that considers maintenance and fire extinguishing performance together is reviewed, and supported systematically with a relevant checklist.

Abstract:
The Kashima petrochemical complex and its Fukashiba industrial wastewater treatment plant are described. When the factories of the complex discharge the wastewater, they must be in compliance with the standards designated in the Sewage Law of Japan, because they are users of the public sewage system. Ten of 81 factories discharged the wastewater containing identified toxics, and they treated corresponding toxic items before discharging to sewers. The wastewater of the factories was constantly monitored by the office of Kashima sewage works, and there had been few troubles with the operation of Fukashiba treatment plant. However, sludge contained cadmium at relatively high concentration in Fukashiba treatment plant, compared with sludge of the domestic sewage treatment plants. The sources of Cd were possibly the use of large amount of slaked lime in these factories. Prior to the construction of any new manufacturing plant, the office of Kashima sewage works practiced the test of biodegradability and toxicity of potential wastewater from the plant. The analytical method of GC/MS became a useful tool to confirm biodegradability and toxicity of substances in the wastewater from each plant.

Abstract:
The technological advancements promote the rise of the fourth industrial revolution, where key terms are efficiency, innovation, and enterprises’ digitalization. Market globalization, product mass customization, and more complex products need to reflect on changing the actual design methods and developing business processes and methodologies that have to be data-driven, AI-assisted, smart, and service-oriented. Therefore, there is a great interest in experimenting with emerging technologies and evaluating how they impact the actual business processes. This paper reports a comparison among the major trends in the digitalization of a Factory of the Future, in conjunction with the two major strategic programs of Industry 4.0 and China 2025. We have focused on these two programs because we have had experience with them in the context of the FIRST H2020 project. European industrialists identify the radical change in the traditional manufacturing production process as the rise of Industry 4.0. Conversely, China mainland launched its strategic plan in China 2025 to promote smart manufacturing to digitalize traditional manufacturing processes. The main contribution of this review paper is to report about a study, conducted and part of the aforementioned FIRST project, which aimed to investigate major trends in applying for both programs in terms of technologies and their applications for the factory’s digitalization. In particular, our analysis consists of the comparison between Digital Factory, Virtual Factory, Smart Manufacturing, and Cloud Manufacturing. We analyzed their essential characteristics, the operational boundaries, the employed technologies, and the interoperability offered at each factory level for each paradigm. Based on this analysis, we report the building blocks in terms of essential technologies required to develop the next generation of a factory of the future, as well as some of the interoperability challenges at a different scale, for enabling inter-factories communications between heterogeneous entities.

Abstract:
The method for synthesizing optimal plan for cost and time-consuming in full factorial experiment based on the use of Gray code were developed. It allows to search without a complete sort out of all the permutations of options. The catalog of optimal plans of full factorial experiment for a number of factors from 2 to 5 was formed. Check the performance of this method was carried out by the example of research in fiber angle converter into a digital code, and the technological process of manufacturing detail by hot stamping. Optimum plans of the experiment in cost and time-consuming were studied for these objects. It was proved that the sequence of the rows in increasing number of factors levels change must correspond to the sequence of factors in decreasing of cost by changing the levels of the factors.

Abstract:
In many complex planning problems with factored, continuous state and action spaces such as Reservoir Control, Heating Ventilation and Air Conditioning (HVAC), and Navigation domains, it is difficult to obtain a model of the complex nonlinear dynamics that govern state evolution. However, the ubiquity of modern sensors allows us to collect large quantities of data from each of these complex systems and build accurate, nonlinear deep neural network models of their state transitions. But there remains one major problem for the task of control – how can we plan with deep network learned transition models without resorting to Monte Carlo Tree Search and other black-box transition model techniques that ignore model structure and do not easily extend to continuous domains? In this paper, we introduce two types of planning methods that can leverage deep neural network learned transition models: Hybrid Deep MILP Planner (HD-MILP-Plan) and Tensorflow Planner (TF-Plan). In HD-MILP-Plan, we make the critical observation that the Rectified Linear Unit (ReLU) transfer function for deep networks not only allows faster convergence of model learning, but also permits a direct compilation of the deep network transition model to a Mixed-Integer Linear Program (MILP) encoding. Further, we identify deep network specific optimizations for HD-MILP-Plan that improve performance over a base encoding and show that we can plan optimally with respect to the learned deep networks. In TF-Plan, we take advantage of the efficiency of auto-differentiation tools and GPU-based computation where we encode a subclass of purely continuous planning problems as Recurrent Neural Networks and directly optimize the actions through backpropagation. We compare both planners and show that TF-Plan is able to approximate the optimal plans found by HD-MILP-Plan in less computation time. Hence this article offers two novel planners for continuous state and action domains with learned deep neural net transition models: one optimal method (HD-MILP-Plan) and a scalable alternative for large-scale problems (TF-Plan).

Abstract:
The advancement of Industry 4.0 has significantly propelled the widespread application of automated guided vehicle (AGV) systems within smart factories. As the structural diversity and complexity of smart factories escalate, the conventional two-dimensional plan-based navigation systems with fixed routes have become inadequate. Addressing this challenge, we devised a novel mobile robot navigation system encompassing foundational control, map construction positioning, and autonomous navigation functionalities. Initially, employing point cloud matching algorithms facilitated the construction of a three-dimensional point cloud map within indoor environments, subsequently converted into a navigational two-dimensional grid map. Simultaneously, the utilization of a multi-threaded normal distribution transform (NDT) algorithm enabled precise robot localization in three-dimensional settings. Leveraging grid maps and the robot’s inherent localization data, the A* algorithm was utilized for global path planning. Moreover, building upon the global path, the timed elastic band (TEB) algorithm was employed to establish a kinematic model, crucial for local obstacle avoidance planning. This research substantiated its findings through simulated experiments and real vehicle deployments: Mobile robots scanned environmental data via laser radar and constructing point clouds and grid maps. This facilitated centimeter-level localization and successful circumvention of static obstacles, while simultaneously charting optimal paths to bypass dynamic hindrances. The devised navigation system demonstrated commendable autonomous navigation capabilities. Experimental evidence showcased satisfactory accuracy in practical applications, with positioning errors of 3.6 cm along the x-axis, 3.3 cm along the y-axis, and 4.3° in orientation. This innovation stands to substantially alleviate the low navigation precision and sluggishness encountered by AGV vehicles within intricate smart factory environments, promising a favorable prospect for practical applications.

Abstract:
Le grignon d’olive est le coproduit principal généré par le procédé d’extraction de l’huile d’olive. Bien que délétère pour l’environnement, le grignon d’olive est une source potentielle de molécules naturelles bénéfiques pour la santé humaine. Une partie de nos travaux a été consacrée à la caractérisation d’un extrait éthanolique de grignon d’olive. L’analyse par UPLC/MS nous a permis d’identifier 59 métabolites secondaires dont les plus abondants sont l’hydroxytyrosol, le tyrosol, l’oleuropéine aglycone, l’oléoside, l’acide caféique et l’acide pcoumarique. Des tests biologiques ont montré que l’extrait éthanolique était doté d’activité antioxydante, antidiabétique et analgésique. Une deuxième partie s’est focalisée sur l’optimisation des rendements d’extraction des polyphénols du grignon d’olive à l’aide de technologies d’extraction éco-responsables. Ces travaux nous ont amené à conclure que les conditions optimales d’extraction ont été obtenues pour un ratio de (60/40) (EtOH/H2O) à l’aide du procédé d’extraction accélérée par solvant. Dans une dernière partie, une nouvelle approche a été développée visant l’optimisation de l’extraction des composés phénoliques en considérant des huiles végétales comme solvant d’extraction. Basé sur un plan factoriel complet à trois facteurs (type d’huile, température et technique d’extraction), nous avons pu montrer que les conditions optimales de l’extraction des polyphénols du grignon étaient l’extraction assistée par ultrasons dans l’huile d’olive à 65°C
Olive pomace is the main by-product generated through olive oil extraction. Although toxic to the environment, olive pomace is an important source of natural products beneficial to human health. Part of our work focuses on an ethanolic extract of pomace. UPLC/MSanalyses allowed us to identify 59 secondary metabolites, the most abundant of which are hydroxytyrosol, tyrosol, oleuropein aglycone, oléoside, caffeic acid and p-coumaric acid. In addition, biological tests have shown that the ethanolic extract has antioxidant, anti-diabetic and analgesic activities. A second part based on the optimization of polyphenol extraction yields from olive pomace was carried out. This work led us to conclude that 60:40 EtOH: H2O was the best extraction solvent ratio and that “accelerated solvent extraction” was the best extraction process. In the last part, a new approach was developed to optimize the extraction of phenolic compounds using vegetable oils as extraction solvent. Based on a complete factorial design with three factors (type of oil, temperature and extraction technique), we have concluded that the optimal conditions for the extraction of polyphenols from pomace are as follows: extraction with olive oil at 65°C using ultrasound-assisted extraction

Abstract:
¿Por qué ocurre que muchos temas que se instalan en la agenda pública con relativoéxito, no logran trascender y conformarse en políticas o programas concretos? ¿Por qué es tan recurrente que muchos diseños técnicamente robustos se “engaveten” o “abandonen”? ¿Qué es más conveniente cómo diseñador de políticas, ser más técnico o más político? Estas preguntas y similares, son las que han guiado la construcción y análisis del presente estudio de caso. Para responderlas, evidentemente no se puede establecer una respuesta simple, precisa e inequívoca, sin embargo, en estudios como éste se indagan algunas causas posibles. La no indicación en los diseños de los mecanismos y estructuras de implementación, la discordancia entre las políticas territoriales y las políticas nacionales, el mal manejo del marketing y los tiempos políticos, la obsesión con la participación, la planificación o la utilización excesiva de tecnologías, la incapacidad de los diseñadores de políticas para hacer y ver otras cosas que van más allá de sus especialidades; son entre otros factores, los que en este estudio de caso se han identificado como relevantes para lo ocurrencia del fenómeno descrito recién. La importancia de estudiar este tema es que muchas veces se da por hecho que la transición entre una etapa y otra en el ciclo de vida de las políticas públicas es lineal y espontánea, cuando la realidad demuestra con frecuencia que efectivamente no es así. El caso que estuvo bajo análisis fue el proceso de agendación, formulación y toma de decisión del plan estratégico de desarrollo de la zona seca. Esta fue una experiencia que ocurrió en Nicaragua a finales del año 2002. En ella, los alcaldes de once municipios de la mano de una ONG entablaron negociaciones con autoridades del gobierno central con el propósito de encontrar soluciones a problemas ingentes en la zona, logrando desencadenar un proceso extenso de negociación, que si bien alcanzó algunos logros, finalmente no derivó en la implementación de ninguna política pública. El caso fue desarrollado mediante la utilización de la metodología “guía práctica para la elaboración de estudios de caso sobre buenas prácticas en gerencia social” y estuvo orientado específicamente a responder la pregunta de investigación ¿Cuáles son los elementos que deben asegurarse en el proceso de agendación y formulación de una política para que ésta sea susceptible de implementarse?

Abstract:
La construcción de la identidad y la de los intereses nacionales de todo Estado constituyen procesos interdependientes y complementarios que se llevan a cabo de manera intersubjetiva al interior de sus sociedades en una línea de tiempo de largo aliento. En tal sentido, las identidades nacionales son proyectadas en el plano internacional por los líderes de los respectivos Estados, quienes a través de sus ideas, cosmovisiones y decisiones, desempeñan roles internacionales específicos que son percibidos por sus pares en el escenario internacional. De esta manera, la identidad nacional es relacional por la idea y el conocimiento compartido que los tomadores de decisión tienen de su nación, a fin de que pueda ser percibida y comprendida por los líderes de los demás Estados, es decir, se trata una relación entre alter y ego. En esencia, las identidades nacionales son estructuras cognitivas colectivas que los Estados comparten socialmente en el ámbito internacional. En este orden de ideas, tal como se desarrollará en el marco teórico de esta obra, los intereses de los Estados son construidos por las identidades nacionales. Adicionalmente, la identidad nacional y los intereses nacionales son factores fundamentales que influyen sustancialmente en la formulación e implementación de la política exterior de todo Estado. Así las cosas, se pueden identificar factores endógenos (cultura nacional, factores ideacionales y materiales) y exógenos (cultura de la anarquía, patrones de cooperación, competencia o conflicto, distribución de poder, lugar que ocupa un Estado en la jerarquía de poder internacional) que influencian la construcción y proyección de identidad y la definición de los intereses nacionales. Ahora bien, para comprender e interpretar la identidad y los intereses nacionales de un Estado como Colombia se requiere de procesos investigativos y de un diálogo sistemático, interdisciplinar y plural entre académicos y tomadores de decisión. En este caso particular, hemos enfocado el análisis en problemáticas relacionadas con la identidad nacional, la defensa, la seguridad y los intereses estratégicos del Estado colombiano desde una perspectiva multidimensional. Por tanto, la obra es producto de un proceso de investigación y conjunto entre oficiales, activos y de la reserva activa de las FF. MM. de Colombia y de académicos de la Pontificia Universidad Javeriana. Los autores realizaron sus investigaciones y la producción de sus textos en el marco del Curso de Altos Estudios Militares (CAEM) y el Curso Integral de Defensa Nacional (CIDENAL) de la Escuela Superior de Guerra (ESDEGUE). El proyecto fue auspiciado por la Fundación Konrad Adenauer de Colombia como concreción de la cooperación interinstitucional que ha venido llevando a cabo desde hace tres años con la Escuela Superior de Guerra, de modo que esta obra es el resultado del compromiso entre ambas entidades y el Centro de Altos Estudios Militares. El libro que aquí presentamos tiene tres secciones: la primera, denominada Marco teórico, incluye un capítulo en el que se desarrollan conceptos y categorías esenciales para el análisis y la comprensión de las nociones de identidad nacional, interés nacional, tipología de intereses nacionales, poder, tipologías de poder, estrategia nacional, objetivos nacionales, etcétera; la segunda sección tiene como título Perspectivas sobre identidad e intereses nacionales de Colombia y sus capítulos aportan las visiones sobre lo que ha sido el estudio y la formulación de dicha problemática durante los ejercicios académicos en distintas promociones del CAEM y el CIDENAL; la tercera y última sección, Intereses específicos de Colombia, recoge los trabajos sobre el análisis de dichos intereses del país, desde distintos enfoques, con las recomendaciones pertinentes para mejorar su gestión y defensa. De esta forma, confluyen dos visiones o perspectivas de gran trascendencia para promover un conocimiento complejo, sólido, riguroso y complementario sobre cada objeto de estudio determinado por los ejes y capítulos de la obra. Por lo tanto, el primer capítulo es presentado por los profesores Eduardo Pastrana Buelvas y Diego Vera Piñeros, quienes elaboraron un marco teórico desde el constructivismo que pretende entregar herramientas históricas, conceptuales y referentes contextuales, con el propósito de acercarse de una forma más idónea a la comprensión e interpretación de los elementos constitutivos y de las características de los intereses y de la identidad de las naciones. Para ello, parten de un ejercicio genealógico interpretando y rastreando los principales antecedentes del nacimiento del concepto o categoría de intereses e identidad. Igualmente, incorporan las distintas tipologías sobre la identidad y los intereses nacionales, en cuyo desarrollo resaltan la importancia de la relación estrecha que existe entre la concepción del rol nacional y la identidad. Por último, enuncian las concepciones del rol nacional que Colombia ha desempeñado y a través de las cuales ha sido percibida en su devenir histórico. Seguidamente, el segundo eje del libro está compuesto por seis capítulos. El primero de ellos es desarrollado por el mayor general Helder Fernán Giraldo Bonilla y el brigadier general (RA) Fabricio Cabrera Ortiz, autores que trabajaron la proyección nacional de Colombia desde los intereses nacionales. En esa línea, abordan analíticamente cómo la estrategia y el concepto de seguridad nacional en Colombia impactan la proyección del Estado y de las FF. MM. de cara a los desafíos y retos contemporáneos. Por su parte, el segundo capítulo del eje es presentado por el brigadier general de la Fuerza Aérea Colombiana Eliot Benavides González, el brigadier general del Ejército Nacional Erik Rodríguez Aparicio y el contralmirante de la Armada Nacional Óscar Darío Tascón Muñoz, quienes contribuyen con un análisis que parte del estudio y la comprensión de los puntos estructurales de la Apreciación Política Estratégica Nacional (APEN) y de la geopolítica contextual colombiana, en aras de identificar y determinar las amenazas, los problemas y las preocupaciones presentes en el entorno geoestratégico que tiene injerencia en la defensa y la seguridad multidimensional de Colombia. El tercer capítulo del eje es de autoría del profesor Eduardo Velosa Porras y consta de un análisis reflexivo sobre la concepción de nación, la percepción y la contestación del rol nacional en los ámbitos regionales y globales. Para esto, el autor parte de una interpretación sobre los principales roles que ha desempeñado Colombia en los últimos años, además, aborda de forma reflexiva y con relación a los elementos conceptuales y teóricos del rol, a qué identidades responden los roles que el país ha asumido en el marco de los intereses proyectados. Posteriormente, el cuarto capítulo del eje es elaborado por el profesor y estudiante del CIDENAL (2019) Francisco Alfonso Camargo Salas, quien desarrolla una definición y una clasificación de los intereses nacionales. A partir de ello, reflexiona sobre la identidad de Colombia, cómo esta se ha proyectado y, en consecuencia, cómo ha sido percibida en el escenario internacional. Para cerrar el capítulo, el autor presenta una relación analítica sobre el vínculo entre intereses y objetivos nacionales. El quinto capítulo del eje es trabajado por el mayor general (RA) Jorge Alberto Segura Manonegra, quien aborda la construcción del concepto de objetivos nacionales y cómo este impacta la estrategia de seguridad nacional. Para ello, hace una distinción conceptual y teórica sobre los intereses y los objetivos nacionales, y analiza la relación estructural entre objetivos, fines, modo y medios del Estado para la formulación y el alcance de los objetivos nacionales instituidos. El sexto y último capítulo del segundo eje es desarrollado por los coroneles de la Fuerza Aérea Colombiana Pedro Arnulfo Sánchez Suárez y del Ejército de Colombia Óscar Leonel Murillo Díaz, quienes presentan un análisis sobre la identidad nacional en relación con el patriotismo y el nacionalismo. Asimismo, reflexionan sobre las principales funciones de la identidad nacional y proponen un instrumento piloto orientado a interpretar y medir la percepción de la identidad nacional. El tercer eje del libro que versa sobre los intereses específicos de Colombia se compone de ocho capítulos. El primero de ellos es presentado por el brigadier general Óscar Zuluaga Castaño, el coronel Héctor Fabio Aristizábal Mustafá y el coronel Kerly Sánchez Pesca, cuya contribución es un análisis sobre el acceso al espacio exterior como un interés nacional vital de Colombia. Para el efecto, parten de una reflexión sobre la importancia del espacio ultraterrestre de Colombia para el desarrollo del comercio internacional y para la seguridad nacional. En este capítulo, los autores privilegian un enfoque desde el realismo clásico para interpretar y comprender la relevancia del espacio exterior como interés vital de Colombia. A continuación, el segundo capítulo del eje, elaborado por Óscar Cabrera Izquierdo, expresidente ejecutivo del BBVA en Colombia y estudiante del CIDENAL (2019), y por la economista Juana Téllez Corredor, consta de un análisis sobre los principales desafíos y retos de la economía colombiana ante las nuevas tendencias globales. En esa línea, los autores parten de la identificación de patrones y de datos macro y microeconómicos de los últimos años para el país. Con ello, a manera de reflexión prospectiva, se proponen proyectar las alternativas y los escenarios sobre la forma como la economía colombiana podría crecer y fortalecerse de cara a los desafíos globales. El tercer capítulo del eje es desarrollado por la profesora Louise Anne Lowe, quien aborda la protección ambiental como parte del interés nacional de Colombia y plantea un análisis sobre el complejo proceso teórico-práctico de la incorporación de los problemas ambientales en las agendas de los Estados. El cuarto capítulo del eje, cuyo autor es el brigadier general Raúl Flórez Cuervo, presenta una reflexión analítica sobre los intereses nacionales en juego en la Amazorinoquia. Para ello, inicia con un excurso argumentativo sobre la comprensión del valor vital de esta macrorregión para Colombia como Estado-nación y finaliza esbozando la identificación del complejo panorama de los factores que allí generan inestabilidad y tienen impacto en el país. A su vez, el quinto capítulo del eje es presentado por el coronel de Infantería de Marina de la Armada Colombiana Adolfo Enrique Hernández Ruiz y por el profesor Héctor Andrés Macías Tolosa, quienes trabajan los intereses marítimos y fluviales de Colombia. Así entonces, parten de una diferenciación conceptual entre el interés marítimo y el interés fluvial y después abordan de forma reflexiva la importancia que tienen los mares y ríos para la supervivencia del desarrollo de la nación. Para todo ello, los autores privilegian una mirada desde el realismo clásico y el neorrealismo. El sexto capítulo del eje es desarrollado por el profesor Carlos Álvarez Calderón y por la profesional en relaciones internacionales y estudios políticos de la Universidad Militar María Johana Alarcón Moreno, autores que presentan, a manera de reflexión, la identidad de Colombia como un asunto de interés nacional. En ese sentido, argumentan la necesidad de que los símbolos, los héroes, los rituales y los valores ameriten mayor relevancia para los estudios de seguridad y defensa, por lo que referencian que tales factores se constituyen como elementos fundamentales y determinantes de los intereses nacionales colombianos. Posteriormente, el séptimo capítulo del eje es el trabajo de los profesores Andrés Mauricio Valdivieso Collazos y Ricardo García Briceño, junto con la profesional en relaciones internacionales y estudios políticos de la Universidad Militar Sofía Correa Merchán, quienes interpretan cuáles han sido los intereses que los gobiernos de Colombia han priorizado de cara al cumplimiento de los estándares internacionales de derechos humanos. Para el cierre del capítulo, los autores proyectan la relación entre el interés nacional de los últimos dos gobiernos con relación a los procesos de construcción de paz en Colombia. El octavo y último capítulo del eje y del libro es presentado por el profesor Diego Vera Piñeros, la politóloga Paula Prieto y la internacionalista y comunicadora de la Pontificia Universidad Javeriana Daniela Garzón, quienes trabajaron la ciberseguridad, la ciberdefensa, la identidad y los intereses nacionales y de las Fuerzas Militares de Colombia. Para ello, inician con una caracterización de la denominada “cuarta revolución” con el propósito de determinar los procesos de producción que están a la vanguardia en materia de desarrollo, adquisición y uso de tecnologías digitales, físicas y biológicas, orientados a potenciar el crecimiento económico. Cierran el análisis abordando y articulando el interés de integrar los avances de la cuarta revolución a los campos de seguridad y defensa nacional, en aras de mejorar las capacidades institucionales y estatales frente a los desafíos y problemas contemporáneos. Así pues, este libro es una propuesta de reflexión, de análisis, de evaluación y de discusión sobre la o las identidades, el interés o los intereses de Colombia y el rol de las FF. MM. de cara a la construcción y configuración tanto de las identidades como de los intereses nacionales. Por lo tanto, desde una perspectiva interdisciplinaria y multidisciplinaria los autores presentan sus análisis con el principal objetivo de contribuir de forma prospectiva al entendimiento de los posibles escenarios en el marco de los complejos procesos y tendencias globales y regionales. Para los editores y para las instituciones auspiciadoras es muy satisfactorio lograr integrar dos perspectivas o dos visiones desde distintos roles (académicos y oficiales de las FF. MM. activos y de la reserva activa) sobre las diferentes aristas y complejidades de las identidades y los intereses del país. Finalmente, es menester decir que resulta gratificante para los editores poder contar con la participación y la contribución de cada uno de los autores, a quienes extendemos un gran agradecimiento por aceptar el desafío de proponer análisis y reflexiones para estos complicados y difíciles temas que demarcan la agenda política colombiana.

This chapter moves on from simple ‘one-way’ designs to more complex factorial designs. It extends the simple linear model to include interactions as well as average main effects. Interactions are assessed relative to a null additive expectation where the treatments have no effect on each other. Interactions can be positive, when effects are more than additive, or negative, when they are less than expected. The chapter considers in detail the analysis of an example data set concerning the mechanisms of loss of plant diversity following fertilizer treatment.

Abstract:
Plant factories have great potential for mitigating the contradiction between the growing global population and food scarcity. Machine vision plays an important role during automated food production, covering each production stage from raising seedlings, transplanting, management, harvesting and grading to packaging. In this paper, the prospects of machine vision application in plant factories are analyzed, then the present research utilizing this technology are summarized, including plant growth monitoring, robot operation assistance and fruit grading. Through the analyses, it is found that although existing methods have solved various practical problems with the advantages of low cost, high efficiency and high precision, there are still various challenges facing machine vision. Firstly, changing lighting conditions, complex indoor environments and color similarities between a plant’s organs can cause common image segmentation algorithms to fail. The lack of standard agricultural datasets hinders deep learning and unsupervised classification algorithms from making significant progress. Secondly, there are various theoretical knowledge gaps regarding the application of machine vision in the specific plant factory environment, which seriously hinders its application effect. Thirdly, a shortage of special image acquisition devices and supporting facilities has resulted in poor image quality. All these factors hinder machine vision to promote the development of plant factories. Nevertheless, this technology remains a powerful tool and is currently irreplaceable. We believe that machine vision will become more robust, efficient and reliable with the development of computer technology, the application of deep learning and updated algorithms.

Abstract The aim of this chapter is to provide an overview of the importance of the environment (especially the microbial environment) and its inter- action with the immune system in immunopathogenesis and disease susceptibility in Juvenile Idiopathic Arthritis (JIA). Juvenile Idiopathic Arthritis (JIA) consists of a complex of diseases with a multi-factorial pathogenesis [1]. Although genetic predisposition does play a role in disease susceptibility, JIA is not a monogenetic disease [2–4] (See Part 2, Chapter 2.10 “Genetic and Cytokine Associations in JIA”). Aside from genetic susceptibilities, environmental factors play an additional role in the pathogenesis of the disease.

Abstract:
Selecting the optimal light environment for plant growth and development, and reducing the amount of electric energy consumed by lighting are both essential to improve the economic operations of vertical farming. Compared with photosynthetic photon flux density and light period, the effects of light quality on plant morphology and physiology are much more complex. The effect of light quality on plant growth and development has been a hot topic in vertical farming over the past few decades. In this chapter, the effects of monochromatic and polychromatic lights on growth, development and qualities of leafy greens are described. Different morphological and physiological responses to specific spectral stimulation are discussed, followed by common polychromatic spectrums and their effects on plants.

Abstract:
This chapter combines political, labor, and cultural history methodologies to compare the Lockheed aircraft factory in Marietta, Georgia, and the Scripto pen and pencil factory in nearby Atlanta. While the mostly male employees at Lockheed, a majority-white plant, enjoyed the job security delivered by defense contracts at the height of the Cold War military-industrial complex, the Scripto workers, the majority of whom were African American women, faced the more capricious turns of the market. Many of the disparities between these factories stemmed from their common management history found in the career of attorney, businessman, and civic leader, James V. Carmichael. Although situated within close geographical proximity, Lockheed and Scripto helped create disparate racial, political, and cultural worlds in the mid-twentieth century. The tale of these two factories uncovers the stark contrasts between the ways race, gender, and government intervention shaped different sectors of the postwar southern economy.

Abstract:
This chapter details the Industrial Revolution, during which inventions such as steam power and electricity changed humans’ lives drastically as factories producing goods with overwhelming speed and efficiency began to spread around the world. In turn, the industrial society carried significant implications for marriage and relationships. Although the mechanisms at play are complex and not entirely uniform, evidence suggests that industrialization contributed immensely to the rise of the nuclear family. Thus, the home became more idealized and a new, pronounced distinction between public and domestic life emerged. By the end of the nineteenth century, the working classes had fully adopted this new mentality of “separate spheres” and saw home as a welcome retreat from the bustle and hum of the city’s factories. The transition from multigenerational families also coincided with marriages becoming more affectionate. As the economic importance of marriage declined, spouses became lovers, companions, and partners. Ultimately, he structural changes in family formation altered the very ways that family members thought and felt about each other.

This chapter analyzes the interaction effects between the principal design cues of a mobile commerce website, such as background/foreground colors, font text and layout. Three experiments have been conducted based on visits to a fictitious m-commerce website. Experiment 1 manipulates the levels of color contrast: positive contrast (light text on a dark background) versus negative contrast (dark text on a light background). In experiment 2, contrast and font have been manipulated with a complete factorial plan: 2 x 2 (negative vs positive contrast x serif font vs sans serif font). Finally, contrast and layout have been manipulated in a third experimental 2 x 2 plan (negative vs positive contrast x dense vs airy layout). This research involved 219 French participants. Results show significant effects of the positive contrast (light text on a dark background) of the mobile website design on the purchase and revisit intentions of adults. Discussions about the interaction effects of design elements, limitations and directions for future research follow.

Abstract:
The CHP 100 kWe tubular SOFC plant built by Siemens is operating at the Gas Turbine Technologies (GTT) in Turin. The generator started up on the June 2005 and produces electric and thermal power used in the factory. A first period of the activity was needed to lead the operation of the SOFC plant at the nominal condition and to reach the complete conditioning of the SOFC tubular fuel cells. Then, in order to characterize the operation of the generator and of the cogenerative system a first experimental campaign was designed by using the factorial analysis. With these methods, the effect of some independent variables (factors) on the plant operation is analyzed in form of screening tests: the analysis allows one to estimate the significance of the main and combined effects of each considered factor through an analysis of variance (ANOVA) on the experimental data. Moreover, the test plan has been designed by using a simple 2k factorial and a 2k factorial with spherical central composite design (CCD); these approaches allow to obtain respectively first-order and second-order regression models for some chosen dependent variables (i.e. DC and AC electric power, generator voltage, recovered heat etc...). The test plan has been performed at the fixed generator current of 500 Amps with two repetitions for each designed treatment. The factorial analysis has been applied considering two factors (22 factorial analysis): setup temperature of the generator and fuel utilization factor. First, the significance of the main and combined effects of the two considered factor has been evaluated. Then, the obtained data have been analyzed by using the Response Surface Methodology analysis (RSM). Finally, the regression models have been obtained for every dependent variable analyzed, with an outline of the sensitivity coefficient linking the dependent and the independent variables.

Abstract:
In this paper, we leverage the efficiency of Binarized Neural Networks (BNNs) to learn complex state transition models of planning domains with discretized factored state and action spaces. In order to directly exploit this transition structure for planning, we present two novel compilations of the learned factored planning problem with BNNs based on reductions to Boolean Satisfiability (FD-SAT-Plan) as well as Binary Linear Programming (FD-BLP-Plan). Experimentally, we show the effectiveness of learning complex transition models with BNNs, and test the runtime efficiency of both encodings on the learned factored planning problem. After this initial investigation, we present an incremental constraint generation algorithm based on generalized landmark constraints to improve the planning accuracy of our encodings. Finally, we show how to extend the best performing encoding (FD-BLP-Plan+) beyond goals to handle factored planning problems with rewards.

Although it is known that human aneurysmal tissue is remodeled in the disease process [1] and that such reorganization leads to altered function [2], the underlying mechanisms by which such changes remains an important unanswered question in the literature. The purpose of this study is to develop a means for determining the biomechanical alterations that occur within the aorta to better understand aneurysmal disease progression.

Nowadays, the energy factor is growing in importance because it really affects the production costs of factories. Not least, energy regulation and rules are stricter as time goes by. Tools for energy monitoring are needed. The objective of this work is to propose a tool aimed to assess the energy value flowing in a production system, according to the Energy Value Stream Mapping method (EVSM). The final goal is to increase the sustainability of the processes through identification of energy wastes, aiming at eliminating them. The tool is a lean graphic instrument; it permits to represent explicitly the energy flows along the process with respect to the concept of value creation. The tool permits to clearly identify and quantify different types of energy flows concerning different carriers, even in a complex production plant where multiple energy carriers act at the same time. Finally, it will be shown the testing of the tool in a household appliances production system.

Abstract:
Fused deposition modelling (FDM) is a growing additive manufacturing method to produce complex objects without geometrical limitations. In addition, mechanical strength, dimensional accuracy, product development cycle time, and surface properties can be improved depending on the application of the best settings of design variables. There are various printing parameters which influence the mechanical properties and quality of FDM parts. In this study, appropriate printing parameters were determined to obtain desired quality on mechanical properties and dimensional accuracy. Then full factorial design was employed to form experiment set including process parameters. Multiple nonlinear neuro-regression analysis was used for modeling of FDM process. The present study aims at optimization of the FDM process parameters including infill pattern, infill density and build orientation on flexural strength and strain for polylactide (PLA) material. In this regard, optimization algorithms Differential Evolution and Nelder Mead were used to find the best design or elite designs. Third-order polynomial model and hybrid model including polynomial and logarithmic terms were employed as an objective function to define physical phenomena regarding flexural strength and strain, respectively. It was found that (i) maximum flexural strength as 99.66 MPa using a cubic pattern, flat orientation, and 90 % infill density, (ii) minimum ultimate strain as 1.102 % for gyroid pattern, flat orientation, and 47 % infill density.

Abstract:
Abstract Although a complex degradation mechanism, the precursors for Stress Corrosion Cracking (SCC) are simply tensile stress, susceptible material and a corrosive environment as expressed by the textbook Venn Diagram. The majority of in-service failures in civil nuclear reactors relating to SCC of stainless steel components have occurred in sensitized material located in occluded and/or stagnant regions exposed to contaminants or oxygenated conditions etc. However, recent operating events have highlighted the risk of SCC of cold worked austenitic stainless steels exposed to good quality primary coolant. Good quality PWR primary coolant is typically high purity water that is pH controlled via lithium hydroxide dosing, containing sufficient dissolved hydrogen to suppress water decomposition by radiolysis and thereby maintain deoxygenated conditions. This paper explores the thresholds for initiation and growth of SCC in good quality water and outlines a methodology for the management of plant risks through: a) Review of plant components versus the key risk indicators — fabrication processes that introduce cold work, elevated surface hardness, high operational loads, chemical composition and primary circuit operating temperatures. b) SCC growth rate calculations for high-risk sites to determine if SCC initiation could pose a threat to integrity over the plant lifetime. c) Review of the adequacy of existing In-Service Inspection (ISI) regimes for defense-in-depth monitoring for signs of SCC. d) Deployment of supplementary optimized inspection techniques for high risk sites. e) Factoring of operational experience and examination of decommissioned plant components.

Abstract This paper describes an interactive virtual environment for modeling and designing factories and shop floors. The factory building tool is developed as an open architecture in which various modules can be utilized to quickly implement factory design algorithms ranging from plant layout to factory flow analysis. Software modules and utilities have been implemented to allow easy set-up of the visual interface. In this paper this virtual factory is used to implement cellular manufacturing (CM) system. CM has traditionally been a very complicated system to implement in practice. However the productivity rise obtained by the successful implementation of the system has been proved to be immense. Several issues involved in implementing CM within our virtual factory machine modeling and interface designs for defining the cells, are discussed. The mathematical clustering algorithm called Modified Boolean Method was implemented to automatically generate complex virtual environments. The virtual factory makes the process of CM-based factory design a very easy and intuitive process. Virtual factory interface also allows easy reassignment of machines and parts, subcontracting of bottleneck parts and rearranging of machines within the same design environment, making this a productive industrial tool.

Abstract:
Tissue engineering combines principles of the life sciences and engineering to replace and repair damaged human tissue. Present practice generally requires the use of porous, bioresorbable scaffolds to serve as temporary 3D templates to guide cell attachment, differentiation, proliferation, and subsequent regenerate tissue formation. Such scaffolds are anticipated to play an important role in allowing physicians to simultaneously reconstruct and regenerate damaged human tissue such as bone, cartilage, ligament and tendon. Recent research strongly suggests the choice of scaffold material and its internal porous architecture significantly influence regenerate tissue structure and function. However, a lack of versatile biomaterials processing and fabrication methods capable of meeting the complex geometric and compositional requirements of tissue engineering scaffolds has slowed progress towards fully testing these promising findings. It is widely accepted that layered manufacturing methods such as selective laser sintering (SLS) have the potential to fulfill these needs. Our research aims to investigate the viability of using SLS to fabricate tissue engineering scaffolds composed of polycaprolactone (PCL), one of the most widely investigated biocompatible, bioresorbable materials for tissue engineering applications. In this work, we report our recent progress on porous scaffold design and fabrication, optimal SLS processing parameter development using systematic factorial design of experiments, and structural characterization via optical microscopy.

La conservación de recursos hídricos en México se ha convertido en tema prioritario dentro de las agendas gubernamentales; particularmente en la ciudad de México, donde convergen al menos tres administraciones, se formulan planes y proyectos de inversión encaminados a frenar el deterioro de las fuentes de abastecimiento y promover el consumo racional del agua. Sin embargo, la problemática que se enfrenta es muy compleja pues involucra factores físicos (naturales y urbanos), históricos, políticos, económicos y sociales. En respuesta a este reto, el Gobierno del Distrito Federal modificó la Norma 26 que incentiva la producción de vivienda social; la esencia de este cambio es la intención de vincular objetivos medioambientales con proyectos sociales. El presente trabajo pretende analizar la influencia que ejerce esta normatividad en la transformación del quehacer arquitectónico y urbanístico, con el fin de evidenciar la necesidad de implementar nuevos modelos de gestión capaces de adaptarse a los retos emergentes. The conservation of water resources in Mexico has become a major issue within government agendas, particularly in Mexico City, where they converge at least three administrations, formulating plans and investment projects designed to curb the deterioration of supply sources and promote rational water consumption. However, the problem it faces is very complex because it involves physical factors (natural and urban), historical, political, economic and social. In response to this challenge, the Government of the Federal District amended Rule 26 that encourages the production of social housing, the essence of this change intend to link environmental objectives with social projects. This paper aims to analyze the influence of this norm in the transformation of the architectonic and urban task, in order to highlight the need to implement new management models that can adapt to emerging challenges.
