Símbolos helenísticos del poder en la concepción imperial de Calígula

Abstract: The way of exercising power of the Roman Princeps Gaius Caesar Augustus Germanicus, better known by his agnomen Caligula, was largely driven by a different pattern of behavior of that promoted by his predecessors Augustus and Tiberius. Through a kind of ritualized acts, these princeps sought to show respect for the traditional social order and appear only as a primus inter pares among Roman aristocrats. As we can see, in this matter the young Gaius caused a radical change on imperial politics. From the valuation of a series of symbols and actions with strong symbolic connotations, in this work we will attempt to show that such a change was, in part, consequence of a new conception of the imperial power displayed by Caligula. The essence of such conception we must search it in the complex corpus of ideas that came to Rome from the pars orientis of the Roman Empire and based important aspects of the power of the Hellenistic Monarchies

Identidad y memoria como principio de legitimación : el caso de la construcción del poder imperial de Séptimo Severo

Abstract: I will focus on the Roman Empire during the final years of the 2nd century A.D., which are considered by Classical Historiography as critical. This epithet is based on the detection of estructural and circumstancial changes linked to state power’s concept. Emperor Pertinax’s murder in 193 can be understood as the trigger of the civil war extended up to the year 197. During those years the tutelary of state power was jeopardized, when four Emperors were crowned at the same time. By the time this struggle ended, Lucius Septimius Severus was recognized as the victorious general and the first of his name in the new dynastic line. Considering these facts, it is the purpose of my work to analize the rising figure of Septimius Severus, from civil war’s clashing context through which the Emperial legitimacy had to be set.

La poesía bucólica en época de Nerón : lectura virgiliana, ideología senequiana y propaganda imperial

[ES] Durante los pocos años del gobierno de Nerón la poesía bucólica latina experimenta un auge anormal y desarrolla una función propagandística particularmente clara. En este artículo se trata de reconstruir, a partir de textos que hasta ahora no se habían implicado debidamente en la cuestión (cuarta égloga de Virgilio, Apocolocyntosis de Séneca, etc.), las motivaciones inmediatas de este resurgir del género: la poesía bucólica de la época responde en parte a una invitación expresa que Séneca formula en un pasaje de su Apocolocyntosis donde, además, se impone como modelo la égloga cuarta de Virgilio, que proporciona símbolos congruentes con la ideología filohelena de la corte de Nerón y conlleva la identificación entre Augusto y Nerón.

The cross layer RMPA handover: a reliable mobility pattern aware handover strategy for broadband wireless communication in a high-speed railway domain

Enhancing the handover process in broadband wireless communication deployment has traditionally motivated many research initiatives. In a high-speed railway domain, the challenge is even greater. Owing to the long distances covered, the mobile node gets involved in a compulsory sequence of handover processes. Consequently, poor performance during the execution of these handover processes significantly degrades the global end-to-end performance. This article proposes a new handover strategy for the railway domain: the RMPA handover, a Reliable Mobility Pattern Aware IEEE 802.16 handover strategy "customized" for a high-speed mobility scenario. The stringent high mobility feature is balanced with three other positive features in a high-speed context: mobility pattern awareness, different sources for location discovery techniques, and a previously known traffic data profile. To the best of the authors' knowledge, there is no IEEE 802.16 handover scheme that simultaneously covers the optimization of the handover process itself and the efficient timing of the handover process. Our strategy covers both areas of research while providing a cost-effective and standards-based solution. To schedule the handover process efficiently, the RMPA strategy makes use of a context aware handover policy; that is, a handover policy based on the mobile node mobility pattern, the time required to perform the handover, the neighboring network conditions, the data traffic profile, the received power signal, and current location and speed information of the train. Our proposal merges all these variables in a cross layer interaction in the handover policy engine. It also enhances the handover process itself by establishing the values for the set of handover configuration parameters and mechanisms of the handover process. RMPA is a cost-effective strategy because compatibility with standards-based equipment is guaranteed. The major contributions of the RMPA handover are in areas that have been left open to the handover designer's discretion. Our simulation analysis validates the RMPA handover decision rules and design choices. Our results supporting a high-demand video application in the uplink stream show a significant improvement in the end-to-end quality of service parameters, including end-to-end delay (22%) and jitter (80%), when compared with a policy based on signal-to-noise-ratio information.

Analytical efficiency evaluation of a network mobility management protocol for Intelligent Transportation Systems

One of the major concerns in an Intelligent Transportation System (ITS) scenario, such as that which may be found on a long-distance train service, is the provision of efficient communication services, satisfying users' expectations, and fulfilling even highly demanding application requirements, such as safety-oriented services. In an ITS scenario, it is common to have a significant amount of onboard devices that comprise a cluster of nodes (a mobile network) that demand connectivity to the outside networks. This demand has to be satisfied without service disruption. Consequently, the mobility of the mobile network has to be managed. Due to the nature of mobile networks, efficient and lightweight protocols are desired in the ITS context to ensure adequate service performance. However, the security is also a key factor in this scenario. Since the management of the mobility is essential for providing communications, the protocol for managing this mobility has to be protected. Furthermore, there are safety-oriented services in this scenario, so user application data should also be protected. Nevertheless, providing security is expensive in terms of efficiency. Based on this considerations, we have developed a solution for managing the network mobility for ITS scenarios: the NeMHIP protocol. This approach provides a secure management of network mobility in an efficient manner. In this article, we present this protocol and the strategy developed to maintain its security and efficiency in satisfactory levels. We also present the developed analytical models to analyze quantitatively the efficiency of the protocol. More specifically, we have developed models for assessing it in terms of signaling cost, which demonstrates that NeMHIP generates up to 73.47% less signaling compared to other relevant approaches. Therefore, the results obtained demonstrate that NeMHIP is the most efficient and secure solution for providing communications in mobile network scenarios such as in an ITS context.
