    A Lightweight and Flexible Mobile Agent Platform Tailored to Management Applications

    Full text link
    Mobile Agents (MAs) represent a distributed computing technology that promises to address the scalability problems of centralized network management. A critical issue that will affect the wider adoption of MA paradigm in management applications is the development of MA Platforms (MAPs) expressly oriented to distributed management. However, most of available platforms impose considerable burden on network and system resources and also lack of essential functionality. In this paper, we discuss the design considerations and implementation details of a complete MAP research prototype that sufficiently addresses all the aforementioned issues. Our MAP has been implemented in Java and tailored for network and systems management applications.Comment: 7 pages, 5 figures; Proceedings of the 2006 Conference on Mobile Computing and Wireless Communications (MCWC'2006

    The early Cycladic settlement at Dhaskalio, Keros: preliminary report of the 2008 excavation season

    Get PDF
    The 2008 excavations on the small island of Dhaskalio opposite Dhaskalio Kavos on the Cycladic island of Keros are reviewed. An account is given of the survey, recording many walls of the early Bronze Age, and of the excavations, continued from the 2007 season. Excavations at the summit of Dhaskalio revealed a substantial building 16 m long and 4 m wide, within which was discovered the ‘Dhaskalio hoard’ comprising a chisel, an axe-adze, and a shaft-hole axe of copper or bronze. Study of the pottery reveals continuity, within which a sequence of three phases within the Early Cycladic II and III periods can be established. Excavations were continued and concluded within the Special Deposit at Kavos South with the recovery of many more special but fragmentary materials including marble vessels and figurines. Specialist studies for the geomorphology, geology, petrology, ceramic petrology, metallurgy and environmental aspects (botanical and faunal remains, phytoliths) are in progress. No more fieldwork is planned prior to final publication of the 2006 to 2008 seasons

    Method for making a microporous membrane

    Get PDF
    A method for making a microporous membrane comprises the steps of: providing a plurality of carbon nanotubes having a hollow interior diameter of 20 Angstroms or less; sonicating the plurality of carbon nanotubes utilizing a solution comprising deionized, distilled water and a surfactant that coats at least one of the plurality of carbon nanotubes; collecting the coated carbon nanotubes; forming a matrix that supports the plurality of carbon nanotubes; embedding the coated carbon nanotubes into the matrix; rinsing the coated nanotubes to remove at least a portion of the surfactant; curing the nanotube-matrix assembly; and cutting the nanotube-matrix assembly to a particular thickness so as to open the ends of the embedded nanotubes. The hollow interiors of the plurality of embedded carbon nanotubes comprise the pores of the microporous membrane

    Coal Pyrolysis

    Get PDF
    Prompted by the need of non-petroleum-based fuels, coal research has reemerged to center stage after a lengthy dormant period. Pyrolysis research, in particular, has gained considerable momentum because of its close connection to combustion, hydropyrolysis and liquefaction. Spectroscopic and other instrumental techniques are currently producing prodigious information about coal structure and pyrolysis mechanisms, while modeling efforts are breaking new ground in sorting out chemical and physical phenomena to provide a fundamental although simplified description. The continuing generation of experimental data will lead to revisions, in some cases drastic, of current structural and kinetic precepts. Yet, the postulates and assumptions of current work provide a meaningful starting point in elaborating theoretical descriptions of greater validity and applicability. This monograph was written to organize recent results of pyrolysis research. Experimental and theoretical aspects, given approximately equal weight, are discussed in the light of basic chemical and physical mechanisms. With this orientation the monograph should be useful to chemists, engineers and graduate students with interests in coal research.

    The misadventures of the European Social Charter in Greece

    Get PDF
    Greece has signed and ratified the ESC and all its amending and additional protocols. Nevertheless, the implementation of the Charter rights was found to be on a rough path. Specifically in the era of the tripartite creditors’ administration (“the Troika”) of the country’s economic affairs (2010-2019) Parliament was forced to pass measures, so called austerity measures, in overt violation of many fundamental employment rights enshrined in the Charter. This led to the delivery of decisions of non-conformity by the ECSR on relevant collective complaints filed by representative domestic trade unions against the Greek State. The latter could not escape the negative outcome of the proceedings, by asserting that the Government had not acted of its own free will but that they were forced to enact such measures under the creditors’ threat of the country’s going bankrupt. In 2016 the country ratified the rev. ESC. Nevertheless, as shown in the case of implementation of article 24 on the principle of dismissal only with a valid reason, the Greek legal practice, even after the Troika had left the country, could not absorb the function and the scope of values underlying social rights, mainly due to the unreadiness of the involved legal circles, but also on the account of the   recently dominant neoliberal shift in the country.Greece has signed and ratified the ESC and all its amending and additional protocols.

    Filtering apparatus and method of use

    Get PDF
    A filtering apparatus comprises a microporous membrane and an actuator. The membrane is positioned to traverse across the hollow interior of a conduit used for the transport of molecules in bulk. In one example, the pores of the membrane comprise a plurality of open-ended carbon nanotubes. The actuator comprises a transducing material such as a polyvinyledene fluoride film that is operatively positioned in contact with the membrane and is capable of propagating acoustic vibration onto the membrane at a particular frequency so as to hasten the movement of the molecules through the membrane. Similarly, a method of filtering water comprises the steps of: (a) sifting molecules of water through the membrane, the pores of the membrane comprising a plurality of carbon nanotubes; and (b) propagating acoustic vibration onto the microporous membrane at a libration frequency of ice so as to hasten movement of the water molecules within the carbon nanotubes
