Making more flexible ATISMART+ model for traffic simulations using a CAS

Traffic simulations usually require the search of a path to join two different points. Dijkstra’s algorithm [1] is one of the most commonly used for this task due to its easiness and quickness. In [2, 3] we developed an accelerated time simulation of car traffic in a smart city using Dijkstra’s algorithm to compute the paths. Dijkstra’s algorithm provides a shortest path between two different points but this is not a realistic situation for simulations. For example, in a car traffic situa- tion, the driver may not know the shortest path to follow. This ignorance can be produced, among others, because one of the following two facts: the driver may not know the exact length of the lanes, or, even knowing the exact length, the driver may not know how to find the shortest path. Even more, in many cases, a mixture of both facts occurs. A more realistic simulation should therefore consider these kind of facts. The algorithm used to compute the path from one point to another in a traffic simulation might consider the possibility of not using the shortest path. In this talk, we use a new probabilistic extension of Dijkstra’s algorithm which covers the above two situations. For this matter, two different modifications in Di- jkstra’s algorithm have been introduced: using non-exact length in lanes, and the choice of a non-shortest path between two different points. Both modifications are used in a non-deterministic way by means of using probability distributions (classi- cal distributions such as Normal or Poisson distributions or even "ad hoc" ones). A precise, fast, natural and elegant way of working with such probability distributions is the use of a CAS in order to deal with exact and explicit computations. As an example of use of this extension of Dijkstra’s algorithm, we will show the ATISMART+ model. This model provides more realistic accelerated time sim- ulations of car traffics in a smart city and was first introduced in [4] and extended in [5]. This model was developed combining J AVA for the GUI and M AXIMA for the mathematical core of the algorithm. The studies developed in the above mentioned works, dealt with Poisson, Ex- ponential, Uniform and Normal distributions. In this talk we will introduce, as a novelty, the possibility of using other continuous probability distributions such as: Lognormal, Weibul, Gamma, Beta, Chi-Square, Student’s t, Z, Pareto, Lo- gistic, Cauchy or Irwin-Hall, and other discrete distributions such as: Bernouille, Rademacher, Binomial, Geometric, Negative Binomial or Hypergeometric. Even 1 more, this new version allows to deal with any “ad-hoc” continuous, discrete or mixed user’s distributions. This fact improves the flexibility of ATISMART+ model.Universidad de Málaga.

Se anaizan los casos de Qart Hadasht (Cartagena), Castillo de Doña Blanca (Puerto de Santa Marta, Cádiz), Lucenfum (Toasal de Manises Alicante) Carmo (Carmona, Sevilla) y otros, con especial atención a la dudad púníca de Carteia (San Roque, Cádiz). Se añade una nueva propuesta acerca de la posible existencia de un campamento púnico fortificado en la antigua Tarraco (Tarragona)

Acepciones semánticas sugeridas por las diferentes versiones de Sinuhé

The comparison and critical study of the different versions of Sinuhe is a valuable source of information on the Egyptian language, and particularly on the meaning and use of certain terms. This possibility has not been pursued so far because of the underestimation of later school versions of the text, specially the Ashmolean ostracon version. It is certainly an unjustified underrating, as the eight passages analysed in this paper show.La comparación y estudio crítico de las versiones de Sinuhé es una valiosa fuente de información sobre la lengua egipcia, y especialmente sobre el significado y uso de ciertos términos. Hasta ahora no había sido explotada esta posibilidad debido a la subestima de la que son objeto las versiones más modernas y escolares del texto, sobre todo la versión del Ashmolean ostracon; subestima en absoluto justificada, como bien muestran los ocho pasajes analizados

Intérpretes y traducciones en el Egipto imperial

Un aspecto relevante que acompaña al desarrollo de cualquier política exterior es cómo superar los problemas de comunicación entre gentes de distintas lenguas. Esto es particularmente interesante en el caso de los primeros estados del Próximo Oriente y la construcción de sus ‘imperios’. Embajadores, mensajeros, traductores y traducciones jugaron un papel relevante que es a menudo menospreciado. En el presente artículo se revisará parte de la abundante documentación sobre la construcción del imperio egipcio en la antigüedad y los contactos lingüísticos entre los egipios y sus vecinos derivados de la nueva situación política

Repetitive Movements in Melon Cultivation Workers under Greenhouses

Musculoskeletal disorders cause serious problems that affect workers in many sectors. The objective of this study is the ergonomic analysis of melon cultivation farmers in Almeria-type greenhouses. For this, the rapid upper limb assessment (RULA) method has been applied after carrying out a detailed process of observing the farmers’ tasks. The study shows that 65% of the postures have a very-high-risk level, 26% high, 9% average, and no posture is found with a low risk. They also show that in 69.57% of the postures, the upper limbs are less affected than the others such as the neck, trunk, and lower limbs. Measures are proposed to improve the working conditions for workers

Algunas soluciones cartográficas aplicadas a la Física solar

El objetivo de esta tesis es estudiar algunas observaciones históricas del Sol usando diferentes herramientas cartográficas y de cálculo para obtener coordenadas heliográficas de las manchas solares. En primer lugar, revisamos los estudios sobre la forma del Sol y los sistemas de referencia utilizados así como las relaciones entre la posición de la Tierra en su órbita, la orientación del Sol y las coordenadas de las manchas solares. A partir de una superficie de referencia esférica para el Sol, aplicamos la teoría clásica de proyecciones cartográficas a las observaciones históricas de manchas solares. En el primer caso de estudio analizado, recuperamos las observaciones perdidas de S.T. Soemmering (entre 1826 y 1829), gracias al material gráfico que L. Thilo y R. Carrington publicaron sobre estas observaciones. También hemos obtenido las coordenadas de las manchas solares dibujadas por el profesor B. Sestini en Washington en 1847 utilizado el programa informático HSunpots. También hemos obtenido las coordenadas de las manchas de las observaciones astrométricas realizadas por B. Oriani en Milán en los años 1778 y 1779. Por último, hemos estudiado la asimetría hemisférica de las manchas solares observadas durante el mínimo de Maunder (1645-1715) gracias a los datos y el material gráfico publicado por Spörer (1889) y Ribes y Nesme-Ribes (1993). Así, hemos desarrollado un conjunto de métodos que pueden ser aplicados a las diversas características de las observaciones históricas de manchas solares.The aim of this thesis is to study some historical observations of the Sun using different cartographic and computation tools to obtain heliographic coordinates of the sunspots. First, we review the studies on the shape of the Sun and the reference systems used as well as the relationships between the position of the Earth in its orbit, the orientation of the Sun and the coordinates of the sunspots. From a spherical reference surface for the Sun, we apply the classic theory of map projections to the historical observations of sunspots. In the first case, we recovered the lost observations of S.T. Soemmering (between 1826 and 1829) from the graphic materials on these observations published by L. Thilo and R. Carrington We have also obtained the coordinates of sunspots observed by Professor B. Sestini in Washington in 1847 using the software HSunpots. We have also obtained the coordinates of the spots of the astrometrical observations made by B. Oriani in Milan in the years 1778 and 1779. Finally, we have studied the hemispheric asymmetry of the sunspots observed during the Maunder minimum (1645-1715) from the data and graphical materials published by Spörer (1889) and Ribes and Nesme-Ribes (1993). Thus, we have developed a set of methods that can be applied to the diverse characteristics of historical observations of sunspots

Aspectos de la diplomacia del Antiguo Egipto. Hasta ca. 1320 a. C.

Egyptian texts show how the peaceful contacts with trading aims hold by Egypt with its neighbours since the beginning of its history got formalized and controlled by the administration at the end of the 20th and beginning of the 19th century BC. These contacts took place through the «commissioner» (wpwtyw), acting as guide-interpreter or messenger of the king, or speaker or deputy of foreign embassies before the king. The relevance of the commissioners' role in the foreign affairs of the XVIIIth dynasty increased gradually, their actions being identified with those of the king himself, and their kingdom borders (t3š) with the perimeter of their actions.Los textos egipcios dejan constancia de que los contactos pacíficos con intenciones comerciales que Egipto mantenía con territorios vecinos desde los comienzos de su historia comenzaron a regularizarse y a formalizarse a finales del siglo XX y comienzos del XIX a. C. Estos contactos estaban mediatizados por la figura del comisionado (wpwtyw), que actuaba como guía-intérprete o mensajero del rey, o como potavoz o representante de las embajadas extranjeras ante el rey. El comisionado fue adquiriendo un mayor protagonismo en los asuntos exteriores de la monarquía bajo la dinastía XVIII; sus acciones se identificaban con las del propio rey y, como consecuencia, hasta las fronteras del reino (t3š) se identificaban con el perímetro de sus acciones

Knowledge Transfer in Commercial Feature Extraction for the Retail Store Location Problem

Location is the most important strategic decision in retailing. The location problem is markedly complex and multicriteria. One of the key factors to consider is the so-called balanced tenancy —i.e., the degree to which neighboring businesses complement each other. There are several network-based methodologies that formalize the notion of balanced tenancy by capturing the spatial interactions between different commercial sectors in cities. Some of these methodologies provide indices that have been successfully used as input features in location recommendation systems. However, from a predictive perspective, it is still unknown which of the indices provides best results. In this work, we analyze the performance of six of these indices on a set of nine Spanish cities. Our results show that the combined use of all of them in an ensemble model such as random forest significantly improves predictive accuracy. In addition, we explore the effect of knowledge transfer between cities from two different perspectives: 1) quantify how much the quality of solutions degrades when the balanced tenancy of a city is explored through the indices obtained from another city; 2) investigate the interest of network consensus approaches for knowledge transfer in retailing.Spanish Ministry of Science, Innovation and Universities through Excellence Network under Grant RED2018-102518-T, in part by the Spanish State Research Agency under Grant PID2020-118906GB-I00/AEI/10.13039/501100011033, and in part by the Junta de Castilla y León Consejería de Educación under Grant BDNS 425389
