Thwarting drone-waged denial of service attacks on a network
Embodiments are directed towards detecting and thwarting incoming network requests by either throttling and/or redirecting the attack requests towards a honeypot.

Distributed computation system incorporating agent network, paths and associated probes
A system and method of distributed computation based upon a novel partitioning of computer networks. In the distributed computing system of the present invention, instructions are disseminated to select agents on a computer network, each of which is a member of at least one “path,” a path being an ordered set of one or more connected agents within the network. The computation is then performed by the agents along the path, and any results then returned.

This vastly increases the expressive power of a single network to be not only the sum of its parts, but the sum of all possible configurations of those parts on a graph. The basic components of the computing system are agents, probes and paths. The agents are interconnected forming a network and a path is an ordered sequence of agents. Information is exchanged between agents by the sending and receiving of probes between the agents in the network. |

Method and apparatus for use with received electromagnetic signal at a frequency not known exactly in advance
In a software receiver, a received electromagnetic signal is sampled in “slices”, each having a duration of some multiple of a reference frequency. The samples of each slice are correlated with values in a pair of reference signals, such as sine and cosine, at the reference frequency. This yields a two-tuple for each slice, which two-tuples may be stored. The stored two-tuples can be simply added to arrive at a correlation value of narrower bandwidth than that of any slice taken alone. The stored two-tuples can be taken in sequence, each rotated by some predetermined angle relative to its predecessor in sequence, and the rotated two-tuples summed to arrive at a correlation value with respect to a frequency that is offset from the reference frequency to an extent that relates to the predetermined angle. In this way, the receiver is able to proceed despite the transmitted frequency not being known exactly in advance and does not require prodigious storage or computational resources. |

The converter device comprises: a first power converter comprising a phase leg provided between terminals of the first HVDC connection, the phase leg comprising a positive arm, an inductor, an AC connection and a negative arm. Each one of the positive arm and the negative arm comprises converter cells and one of the converter cells is a first host converter cell. Each converter cell comprises two main switching elements and a storage element, the two switching elements being arranged serially in parallel with the energy storage element. The converter device also comprises a power converter section comprising a first converter cell comprising at least two switching elements connected serially in parallel with the energy storage element of the first host converter cell. The converter device is arranged to control the switching elements of the first switching element string in dependence of the state of the main switching elements of the first host converter cell. |
