摘要:
In one embodiment, a method of monitoring a network. The method includes: receiving, from each host of a set of two or more hosts of the network, a corresponding vector of M components constructed based on data packets received at the host during a time period, M being an integer greater than 1; and, based on the constructed vectors, using an expectation-maximization algorithm to estimate a cardinality distribution for the hosts in the set, wherein constructing a vector includes updating a component of the vector of the corresponding host in response to the corresponding host receiving a data packet, the updating including selecting the component for updating by hashing one or more fields of the data packet received by the corresponding host.

In one embodiment, the method includes reducing a beam width of transmission to increase an open-loop beamforming gain, reducing a channel bandwidth of the transmission to increase a channel bandwidth gain, and increasing a sequence length of the transmission to increase a sequence length gain. In this embodiment, a gain improvement is based on the product of the open loop beamforming gain, the channel bandwidth gain and the sequence length gain.
摘要:
Circuit elements such as DC blocking capacitors used in communication such as a serial communication link between two or more electrical components are disposed in pre-existing openings in a support structure that supports at least one of the two electrical components. The openings may be plated and used for signal transmission from the one electrical component to a printed circuit board (PCB) supporting the substrate. The DC blocking capacitors may be oriented substantially vertically, and a non-conducting material may be disposed in each opening in the substrate such that the non-conducting material at least partially surrounds and fixes the orientation of the DC blocking capacitor disposed in the opening.

The method includes: collecting memory application information of at least one node of a computer system that is implementing the method; predicting a memory overload period and an overload memory size of a first node where memory overload will occur based on the memory application information; and scheduling a memory space according to the memory overload period and the overload memory size.
摘要:
An expandable apparatus for use in a borehole includes a tubular body having at least one opening extending between a longitudinal bore of the tubular body and an outer surface of the tubular body and at least one member positioned within the at least one opening of the tubular body. The at least one member is configured to move between a retracted position and an extended position. An actuation structure is positioned within the tubular body. The actuation structure is coupled to the at least one member and is configured to move the at least one member from the retracted position to the extended position responsive to a flow rate of drilling fluid passing through the longitudinal bore.
摘要:
A method for removing a plurality of dielectric films from a supporting substrate by providing a substrate with a dielectric layer overlying another dielectric layer, contacting the substrate at a first temperature with an acid solution exhibiting a positive etch selectivity at the first temperature, and then contacting the substrate at a second temperature with an acid solution exhibiting a positive etch selectivity at the second temperature. The dielectric layers exhibit different etch rates when etched at the first and second temperatures. The first and second acid solutions may contain phosphoric acid. The first dielectric layer may be silicon nitride and the second dielectric layer may be silicon oxide. Under these conditions, the first temperature may be about 175° C. and the second temperature may be about 155° C.
