Computer-aided analysis and design procedure for rotating induction machine magnetic circuits and windings
2018
The aim of this study is to present a new, accurate, and user-friendly software procedure for the analysis and rapid design of rotating induction machine windings, considering both the electric and the magnetic specifications of the machine itself. This procedure is a valid aid for quick first stage design without the necessity of using finite element method (FEM)-based design procedures. FEM can be used in a second design phase in order to refine the first stage results. The design procedure is hereafter outlined and some examples show its capability.
Development of a low-alcoholic fermented beverage employing cashew apple juice and non-conventional yeasts
2019
Cashew apples are by-products in the production of cashew nuts, which are mostly left to rot in the fields. Cashew apple juice (CAJ), a highly nutritious beverage, can be produced from them. It is rich in sugars and ascorbic acid, but its high polyphenol content makes it bitter and astringent, and therefore difficult to commercialize. The kingdom of fungi contains more than 2000 yeast species, of which only a few species have been studied in relation to their potential to produce aroma compounds. The aim of this research was to develop a new low-alcoholic fermented beverage to valorize cashew apples. For this purpose, a screening was carried out employing non-conventional yeast species and …
District heating networks: enhancement of the efficiency
2019
International audience; During the decades the district heating's (DH) advantages (more cost-efficient heat generation and reduced air pollution) overcompensated the additional costs of transmission and distribution of the centrally produced thermal energy to consumers. Rapid increase in the efficiency of low-power heaters, development of separated low heat density areas in cities reduce the competitiveness of the large centralized DH systems in comparison with the distributed cluster-size networks and even local heating. Reduction of transmission costs, enhancement of the network efficiency by optimization of the design of the DH networks become a critical issue. The methodology for determ…
The TeRiFiQ project: Combining technologies to achieve significant binary reductions in sodium, fat and sugar content in everyday foods whilst optimi…
2017
International audience; Most developed countries are confronted with rising rates of diseases related to unhealthy eating habits, particularly the excessive consumption of salt, saturated fat and free sugars. However, fat, sugars and salt in food influence not only its nutritional qualities but also its sensory properties, safety (e.g. shelf life) and affordability. The main challenge is to formulate healthier foods that are acceptable to consumers. In this context, the overall objective of TeRiFiQ was to achieve significant binary reductions in the salt-fat and sugar-fat contents of frequently consumed food products around Europe, while, at the same time, ensuring the products’ nutritional…
Contributions to Branch-and-Price-and-Cut Algorithms for Routing Problems
2019
This article deals with new exact branch-and-price-and-cut algorithms for the solution of routing problems. Specialized methods for the pickup-and-delivery problem (PDP), the truck-and-trailer routing problem (TTRP), the periodic vehicle routing problem (PVRP) and a service network design and hub location problem (SNDHLP) are presented. We develop a new technique for the acceleration of bidirectional labeling algorithms by a dynamic choice of the merge point. Moreover, for variants of the PDP, the bidirectional labeling can be effectively applied for the first time. In the TTRP, we model the extension to a 2 days planning horizon and the consideration of a quantity-dependent transfer time. …
Branch-and-price-and-cut for a service network design and hub location problem
2015
In the context of combined road-rail freight transport, we study the integrated tactical planning of hub locations and the design of a frequency service network. We consider a number of real-world constraints such as multiple transshipments of requests at hubs, transport time limits for requests, request splitting, and outsourcing possibilities. To our knowledge, the combination of problem features we deal with has not been described before. We present a path-based model and solve it with a branch-and-price-and-cut algorithm. Computational experiments show that large realistic instances from a major German rail freight company can be solved close to optimality within one hour on a standard …
Bim and architectural heritage: Towards an operational methodology for the knowledge and the management of cultural heritage
2016
The study aims to answer the growing need for virtuously organize informational apparatuses related to Cultural Heritage. We propose a methodology that integrates multidisciplinary processes of interaction with information aimed at survey, documentation, management, knowledge and enhancement of historic artifacts. It is needed to review and update the procedure of instrumental data acquisition, standardization and structuring of the acquired data in a three-dimensional semantic model as well as the subsequent representability and accessibility of the model and the related database. If the use of Building Information Modeling has in recent years seen a consolidation in the procedures and the…
El Sistema musical pitagórico y la proporción áurea en la arquitectura: El Erecteión
1999
El objetivo de este estudio analiza las interrelaciones entre la música, la proporción áurea y la arquitectura helénica, aplicado al Erecteión. Al establecer las ligazones existentes entre ambas manifestaciones artísticas actualizamos la máxima de Spengler que vinculaba el arte de las matemáticas con la música y las artes plásticas. Al mismo tiempo hemos elaborado de manera completa el desarrollo matemático de la proporción aúrea.

How to Define Games and Why We Need to
2019
This article provides guidelines on how to make useful game definitions and discusses when that is a worthwhile undertaking. It examines a recent article attempting to define videogames (Bergonse in Comput Games J 6(4):239–255, 2017. https://doi.org/10.1007/s40869-017-0045-4), and uses it as an example to discuss game definitions in general. It concludes with reasons why making a final definition of games is not possible and why we need to continue to define games. peerReviewed
