Abstract Systemic approach to design of factories requires that engineering, organisational and economic aspects should be considered concurrently. That prompts the need to develop a solution, based on the state-of-the-art IT technologies, to enable us to solve the problems associated with foundry production planning. The paper outlines a methodology of creating the simulation model of a virtual foundry, as a tool for foundry design. An integrative approach is suggested for development of a complete foundry model, enabling the design of more efficient production systems. The underlying principles of such models are discussed, the basic stages involved in the methodology are outlined and the range of its applicability is defined.

The Social

Advancing the state of the art of simulation in the social sciences requires appreciating the unique value of simulation as a third way of doing science, in contrast to both induction and deduction. Simulation can be an effective tool for discovering surprising consequences of simple assumptions. This chapter offers advice for doing simulation research, focusing on the programming of a simulation model, analyzing the results, sharing the results, and replicating other people’s simulations. Finally, suggestions are offered for building a community of social scientists who do simulation.

Abstract Background Membrane proteins are key gates that control various vital cellular functions. Membrane proteins are often detected using transmembrane topology prediction tools. While transmembrane topology prediction tools can detect integral membrane proteins, they do not address surface-bound proteins. In this study, we focused on finding the best techniques for distinguishing all types of membrane proteins. Results This research first demonstrates the shortcomings of merely using transmembrane topology prediction tools to detect all types of membrane proteins. Then, the performance of various feature extraction techniques in combination with different machine learning algorithms was explored. The experimental results obtained by cross-validation and independent testing suggest that applying an integrative approach that combines the results of transmembrane topology prediction and position-specific scoring matrix (Pse-PSSM) optimized evidence-theoretic k nearest neighbor (OET-KNN) predictors yields the best performance. Conclusion The integrative approach outperforms the state-of-the-art methods in terms of accuracy and MCC, where the accuracy reached a 92.51% in independent testing, compared to the 89.53% and 79.42% accuracies achieved by the state-of-the-art methods.

The IWA conference on water economics, statistics and finance involved multidiscipline participants from academia and industry and decision makers. A number of important issues were considered such as: how utilities are financed, the variety of water tariff structures, measurement of performance and benchmarking, national and regional water industry statistics, water facts, regulation, economic aspects, costs/benefits, feasibility analysis, as well as funding possibilities and practices. This is an overview paper that gives the state of the art on these issues, new directions, which were presented at the conference and the up-to-date literature.

The aim of this paper is to describe a developed simulation model of the gPTP protocol for time synchronization in OMNeT++ using the INET library. gPTP is part of the IEEE TSN standards. Unfortunately, there is currently no simulation model of gPTP available. Therefore, we developed a new simulation model, compared it to results from the state-of- the-art, and would like to share it with the OMNeT++ community. The simulation model is based on the IEEE 802.1AS specification for full-duplex Ethernet according to a given network topology and use case scenario to analyze the results of the simulation as well as to provide a comparison with results from the state-of-the-art. Time synchronization and propagation delay measurements between time-aware systems are considered and results show that the simulation model works as expected.

<p>El lulo (<em>Solanum quitoense </em>Lam.) es un frutal andino importante en Colombia, con oferta deficitaria e importación desde Ecuador, para suplir la demanda nacional. La siembra se desarrolla casi exclusivamente con materiales locales, con existencia de un solo cultivar mejorado en el país. El cultivo se realiza con base en el conocimiento tradicional y recomendaciones técnicas; su sustento investigativo es escaso y en la mayoría de los casos apoya aspectos y problemas puntuales. Se estudió el estado actual de las investigaciones relacionadas con el conocimiento sobre esta especie, para su análisis y el diseño de procesos que apoyen el desarrollo de sistemas de producción sostenibles y eficientes de la misma, desde la óptica ambiental y productiva, como también actividades de valor agregado y poscosecha. En la revisión actual se presenta la información relacionada con los componentes de la función productiva: genotipo, ambiente e interacción genotipo X ambiente.  </p><p> </p><p><strong>State of knowledge review on the productive function of lulo (</strong><strong><em>Solanum quitoense </em></strong><strong>Lam.) in Colombia</strong>  </p><p>Lulo (<em>Solanum quitoense </em>Lam.) is an important Andean fruit in Colombia, with a national supply deficit, which requires fruit importation from Ecuador to accomplish the consumption demand. Lulo cropping is done almost exclusively with farmer varieties, with just one improved cultivar released in the country. Cultivation is based on local knowledge, as well as technical recommendations without a research support in most of the cases, developed for specific areas and problems, which do not consider the production components as a whole. A search related to the state of the art of the lulo knowledge, was done to identify research key points, for the development of sustainable and efficient production systems, as well as for the support and development of post harvest management and processing procedures. In the current review, a relation of the knowledge related to the production components: genotype, environment and the interaction genotype X environment is included. </p>

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
