Mobile agent based TCP attacker identification in MANET using the traffic history (MAITH)

TCP attacks are the major problem faced by Mobile Ad hoc Networks (MANETs) due to its limited network and host resources. Attacker traceback is a promising solution which allows a victim to identify the exact location of the attacker and hence enables the victim to take proper countermeasure near attack origins, for forensics and to discourage attackers from launching the attacks. However, attacker traceback in MANET is a challenging problem due to dynamic network topology, limited network and host resources such as memory, bandwidth and battery life. We introduce a novel method of TCP attacker Identification in MANET using the Traffic History - MAITH. Based on the comprehensive evaluation based on simulations, we showed that MAITH can successfully track down the attacker under diverse mobile multi-hop network environment with low communication, computation, and memory overhead.

History of MRI

A brief account of the basic principle and methodologies of MRI technique, right from its beginning, are outlined. The final pulse sequence used for MRI using Fourier Imaging (phase encoding), Echo-Planar Imaging (EPI) for detection of a whole plane in a single excitation and T-1 and T-2 contrast enhancement is explained. The various associated methods such as, MR-spectroscopy, flow measurement (MRI-angiography), Lung-imaging using hyperpolarized Xe-129 and He-3 and functional imaging (f-MRI) are described.

History of Computing in India: 1955-2010

The history of computing in India is inextricably intertwined with two interacting forces: the political climate determined by the political party in power) and the government policies mainly driven by the technocrats and bureaucrats who acted within the boundaries drawn by the political party in power. There were four break points (which occurred in 1970, 1978, 1991 and 1998) that changed the direction of the development of computers and their applications. This article explains why these breaks occurred and how they affected the history of computing in India.

Dynamics of history-dependent epidemics in temporal networks

The structural properties of temporal networks often influence the dynamical processes that occur on these networks, e.g., bursty interaction patterns have been shown to slow down epidemics. In this paper, we investigate the effect of link lifetimes on the spread of history-dependent epidemics. We formulate an analytically tractable activity-driven temporal network model that explicitly incorporates link lifetimes. For Markovian link lifetimes, we use mean-field analysis for computing the epidemic threshold, while the effect of non-Markovian link lifetimes is studied using simulations. Furthermore, we also study the effect of negative correlation between the number of links spawned by an individual and the lifetimes of those links. Such negative correlations may arise due to the finite cognitive capacity of the individuals. Our investigations reveal that heavy-tailed link lifetimes slow down the epidemic, while negative correlations can reduce epidemic prevalence. We believe that our results help shed light on the role of link lifetimes in modulating diffusion processes on temporal networks.

Interactions between reflection and praxis in the history of economic thought : the case of the franciscan circles from XIII century Assisi to the present

Resumen: Daniela Parisi analiza el impacto de la vida de San F rancisco de Asís desde la perspectiva de la historia del pensamiento económico. Haciendo referencia particularmente a la atención otorgada en los círculos franciscanos a los signos de los tiempos, la autora traza el camino desde la vida de San Francisco, pasando por la vida de la Orden hasta el presente, y revela los orígenes del movimiento franciscano como un intento de reforma social y religiosa. En primer lugar, el artículo presenta la vida que llevó San Francisco como una “pobreza material voluntaria” en el contexto de los cambios socio-económicos que tuvieron lugar en el siglo XIII, con el advenimiento de la sociedad comercial. Luego, explica cómo la propuesta de San Francisco creció hasta convertirse en una orden religiosa. Finalmente, el artículo intenta iluminar aquellos aspectos en que la Orden Franciscana puede todavía considerarse un signo de los tiempos a través de una existencia comprometida con la pobreza, eliminando lo superfluo de nuestra vida y viviendo en consonancia con el Evangelio.

The pottery from A and C-Group tombs at Serra West in the Museum of Natural History, La Plata

Abstract: The Museum of Natural History, La Plata, Argentina, houses a ceramic collection of the A-Group and C-Group cultures from Nubian tombs at Serra West (AA and ACS cemeteries), on the west bank of the Nile in Lower Nubia. It has been originated from the division after the excavations made by the Franco-Argentine Archaeological Expedition in Sudan between 1961 and 1963, as part of the UNESCO campaigns to save the Nubian monuments.

A theoretical perspective of the Telepinu Myth : archetypes and initiation rites in historical contexts

Abstract: Research on the Telepinu Myth (CTH 324) has shown that it is an inexhaustibly rich document and that therefore the different, and sometimes conflicting, lines of analysis need to be pursued further. In the light of the symbolic evidence presented by this mythological tradition, we propose to focus on the privileged position granted to spatial symbols and to hypothesize the function this Myth served in specific contexts of the Hittite history, characterized by the increase and reduction of lands under Hittite jurisdiction. In this regard, we propose to evaluate the symbolic function that the Telepinu Myth displayed in order to rebuild the sacred space of the territories governed by the Hittites, when they were undergoing changes brought about by increased political and military contact with neighboring societies.

Ramesside, Late Nubian and christian pottery from Serra West in the Museum of Natural History, La Plata

Resumen: El Museo de Ciencias Naturales de La Plata, Argentina, posee una colección de piezas cerámicas provenientes del asentamiento egipcio y de la iglesia de Aksha, y de las tumbas nubias de Serra Oeste, sobre la margen izquierda del Nilo en la Baja Nubia, que pertenecen a las culturas meroítica y del Grupo X. Esta colección es producto del reparto después de las excavaciones realizadas por la Expedición Franco-Argentina en Sudán entre 1961 y 1963, como parte de las campañas de la UNESCO para salvar los monumentos de Nubia.

Peftjauawybast, king of Nen-nesut : genealogy, art history, and the chronology of late libyan Egypt

This paper argues in detail for the identification of Peftjauawybast, King of Nen-nesut (fl. 728/720 BC ), with Peftjauawybast, High Priest of Ptah in Memphis (fl. c. 790–780 BC2), known from the Apis stela of year 28 of Shoshenq III. This identification ties in with a significant lowering of the accepted dates for the kings from Shoshenq III, Osorkon III and Takeloth III to Shoshenq V, and the material culture associated with them. Such a shift seems to be supported by stylistic and genealogical evidence. As a consequence, it is further suggested that the Master of Shipping at Nen-nesut, Pediese i, was perhaps related by descent and marriage to the family of the High Priests of Memphis and King Peftjauawybast.

Eli, Eli, Lama Shabaqtani” la condición cristiana en el Medio Oriente

Resumen: El artículo enfoca la situación de los cristianos del Medio Oriente y trata de formular su destino colectivo en términos de “la condición cristiana”. El argumento central sostiene que la tragedia de la condición cristiana en el Medio Oriente se explica por la crisis del Estado secular provocada tanto por el factor del Islam, así como las intervenciones de potencias europeas desde las cruzadas hasta el período colonial e intervención militar de Estados Unidos en Irak en 2003. En este sentido, la actualidad no es la repetición de la historia, sino la continuidad del mismo padrón de inequidad en distintos períodos históricos dentro de las sociedades musulmanas y el intervencionismo externo/occidental que, tanto en el pasado como en la actualidad, muy pocas veces se ha preocupado por el destino de la cristiandad del Medio Oriente.
