Abstract: A node NI has a protocol stack (10), between application (13) and management (11) layers, and two or more Link level interfaces (12, 14) to network links (31, 32). Protocol stack (10) has a multiple data link interface (101), which may duplicate packets at transmission, to be sent through links (31, 32), respectively. A memory area is reserved. At reception, an identifier (X) is calculated for each incoming packet e.g. form its IP header, and is searched in at least a portion of the reserved memory area; if X is not found (or not found for the source node), the packet identifier (X) is stored in currently reserved portion of the memory area.

Abstract: A process of control of a thermal energy storage unit in the ground includes heat exchangers buried in the ground, each of the exchangers allowing a calorific energy exchange between a heat-conveying fluid traversing it and the ground, the energy storage unit being at the interface between a source and consumer of calorific energy to store thermal energy. One measures the temperature in various points of the ground using buried temperature gauges, the temperatures and flow of a heat-conveying fluid in input and output of the source to determine the thermal power provided by the source, and temperatures and flow of a heat-conveying fluid in input and output of the consumer to determine the thermal power to provide the consumer. One optimizes the storage of thermal energy in the storage unit by selecting active exchangers among the plurality of exchangers according to temperature measurements, flow measurements and thermal power measurements.

Abstract: The invention concerns a method for determining the condition of at least one culture of prokaryotic or eukaryotic cells defined in greater detail herein, including in particular one or more steps for simultaneously analyzing the condition of a large number of biological markers of interest. The inventive method, enables, in some cases, the cellular response to a plurality of modifications of environmental conditions to be simultaneously determined, including, for example, the simultaneous determination of the cellular response to various compounds to be tested.

Abstract: A node NI has a protocol stack (10), between application (13) and management (11) layers, and two or more Link level interfaces (12, 14) to network links (31, 32). Protocol stack (10) has a multiple data link interface (101), which may duplicate packets at transmission, to be sent through links (31, 32), respecitvely. A memory area is reserved. At reception, an idnetifier (X) is calculated for each incoming packet e.g. form its IP header, and is searched in at least a portion of the reserved memory area; if X is not found (or not found for the source node), the packet identifier (X) is stored in currently reserved portion of the memory area.

Abstract: One embodiment of the present invention provides a computer system comprising a first node, adapted to be connected via at least a link to a second node. The first node includes a receiving component capable of receiving repetitively a presence message comprising an indication of a current delay for a status detection of the second node, a handling component capable of determining the status of the second node from a delay derived from received delays, and from the time succession of receipt of said presence messages.
