Resource dimensioning aspect of heterogeneous traffic with different service requirements: Integration versus segregation

In this paper, we consider the ATM networks in which the virtual path concept is implemented. The question of how to multiplex two or more diverse traffic classes while providing different quality of service requirements is a very complicated open problem. Two distinct options are available: integration and segregation. In an integration approach all the traffic from different connections are multiplexed onto one VP. This implies that the most restrictive QOS requirements must be applied to all services. Therefore, link utilization will be decreased because unnecessarily stringent QOS is provided to all connections. With the segregation approach the problem can be much simplified if different types of traffic are separated by assigning a VP with dedicated resources (buffers and links). Therefore, resources may not be efficiently utilized because no sharing of bandwidth can take place across the VP. The probability that the bandwidth required by the accepted connections exceeds the capacity of the link is evaluated with the probability of congestion (PC). Since the PC can be expressed as the CLP, we shall simply carry out bandwidth allocation using the PC. We first focus on the influence of some parameters (CLP, bit rate and burstiness) on the capacity required by a VP supporting a single traffic class using the new convolution approach. Numerical results are presented both to compare the required capacity and to observe which conditions under each approach are preferred

Knowledge integration within an applied mobile robot summer course

This paper presents the use of a mobile robot platform as an innovative educational tool in order to promote and integrate different curriculum knowledge. Hence, it is presented the acquired experience within a summer course named ldquoapplied mobile roboticsrdquo. The main aim of the course is to integrate different subjects as electronics, programming, architecture, perception systems, communications, control and trajectory planning by using the educational open mobile robot platform PRIM. The summer course is addressed to a wide range of student profiles. However, it is of special interests to the students of electrical and computer engineering around their final academic year. The summer course consists of the theoretical and laboratory sessions, related to the following topics: design & programming of electronic devices, modelling and control systems, trajectory planning and control, and computer vision systems. Therefore, the clues for achieving a renewed path of progress in robotics are the integration of several knowledgeable fields, such as computing, communications, and control sciences, in order to perform a higher level reasoning and use decision tools with strong theoretical base

Militarism and Melodrama: The Cultural Work of Combat Death

This essay examines the role of melodrama in the American war film, focusing on three post-WWII examples. The main argument centers on the natural alliance between melodrama and militarism based on a shared intolerance for the notion of death as meaningless and in vain. Both melodrama and military ideology employ elaborate rhetorical and narrative strategies to enfold deaths into larger systems of meaning, such as the nation, or in more personal terms, as a rite of passage. One of the most common narrative devices present in the military melodrama is the death that converts survivors to the values of the virtuous victim. The essay examines the shared conventions and different strategies of the following three films: Sands of Iwo Jima (1949), Platoon (1986), and Top Gun (1986).

Projecte de ruta, patrimoni cultural i natural del municipi de Llançà: "Llançà. Un Passeig pel temps descobrint el Patrimoni"

En aquest Projecte el que es planteja és abraçar el màxim d’elementspatrimonials del municipi i crear una ruta, per conèixer, estudiar i descobrir quins sónels elements més característics, emblemàtics, i més rellevants per després poderincloure’ls en la nostra proposta. En aquesta ruta, acabaran entrant doncs, tant elpatrimoni inventariable, com el patrimoni intangible, sempre i quan tinguin unasingularitat que la facin atractiva i interessant per al visitant. El que es vol és que aquestprojecte sigui una alternativa real a les diferents rutes que es presenten al municipi deLlançà

Ser jove als marges de la cultura: com es relacionen els joves amb l’entorn social i cultural a través d’expressions plàstiques d’art al carrer

En el procés de ser jove hi ha implícites dinàmiques de socialització i de relació. Tot i ser un procés habitual, no deixa de sorprendre la incorporació, a través de l’acció dels joves, de nous valors i nous referents en els constructes culturals ja establerts, que, en termes molt generals, identifiquen fins aquest moment els que en podríem dir la massa adulta. L’article es basa en un treball empíric fet a la ciutat de Tarragona, combinant les opinions directes de 21 joves creadors, l’observació dels carrers (especialment dels graffitis i instal•lacions plàstiques que hi podem trobar) i l’anàlisi de fonts bibliogràfiques i documentals amb les que es planteja els referents teòrics i contextuals

Pla de difusió del Patrimoni Cultural de Pineda de Mar. Tot el que hi ha i no veus

Les idees que han portat a realitzar aquest projecte són les següents: posar en valor i donar a conèixer la realitat patrimonial que té Pineda de Mar, conèixer i documentar el patrimoni cultural de Pineda, actualitzar l’inventari d’elements declarats al municipi, oferir a la ciutat la possibilitat de tenir un turisme cultural, no només un turisme de sol i platja, ser un projecte útil i factible per a l’ajuntament del municipi.Aquestes idees o raons han estat el rerefons per a encaminar i decidir el projecte final de difusió que es presenta en aquest treball.

The 16PF5 and the NEO-PI-R in Spanish and Swiss samples: A cross-cultural comparison

This study compared the Spanish (Castilian) and French versions of the 16PF5 and of the NEO-PI-R in Spanish and Swiss samples. The five-factor solution for the 16PF5 only seems clear for the Castilian version, but not for the French version. Indeed, the congruence coefficients for the Tough-Mindedness and the Self-Control dimensions are low. On the other hand, the five-factor solutions are highly similar for both countries concerning the NEO-PI-R, and the congruence coefficients are above .95 for all five dimensions. The low cross-cultural replicability for the 16PF5 makes it difficult to analyze the differences at the mean level for this inventory. For the NEO-PI-R, the differences are generally very small and globally account for 2.6% of the total variance. Spaniards seem to have slightly lower scores on Actions and slightly higher scores on Dutifulness. These differences could either be due to translation problems, sample selection, or cultural differences.

A review of the cross-cultural equivalence of frequently used personality inventories

Personality inventories are frequently used for career guidance. Some should theoretically depend on cultural context, while others are supposed to be universal. The cross-cultural equivalence is only partial for culture-dependent models, as the locus of control. Concerning models that are supposed to be universal like the one proposed by Cattell or the Five-Factor Model, a partial and a full structural equivalence are, respectively observed. The extent of the scalar equivalence is difficult to assess indicating that more studies should be conducted to understand how culture affects processes underlying the evaluation of personality.

A cross-cultural shortened form of the ZKPQ (ZKPQ-50-CC) adapted to English, French, German, and Spanish languages.

The aim of the present study was to develop a short form of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) with acceptable psychometric properties in four languages: English (United States), French (Switzerland), German (Germany), and Spanish (Spain). The total sample (N = 4,621) was randomly divided into calibration and validation samples. An exploratory factor analysis was conducted in the calibration sample. Eighty items, with loadings equal or higher than 0.30 on their own factor and lower on the remaining factors, were retained. A confirmatory factor analysis was performed over the survival items in the validation sample in order to select the best 10 items for each scale. This short version (named ZKPQ-50-CC) presents psychometric properties strongly similar to the original version in the four countries. Moreover, the factor structure are near equivalent across the four countries since the congruence indices were all higher than 0.90. It is concluded that the ZKPQ-50-CC presented a high cross-language replicability, and it could be an useful questionnaire that may be used for personality research.
