The hybrid resistor-memristor crossbar array may include resistor crossbars, each resistor having a static conductance value. The hybrid resistor-memristor crossbar array may also have a memristor coupled to an output line associated with the resistor crossbar array, wherein the memristor has a variable conductance value, and further wherein the static conductance values and the variable conductance value are set to calculate a matrix-vector multiplication associated with a weight matrix of a neural network. An expected range of coefficients for a weight matrix of a neural network can be given by the Discrete Transform Cosine (DCT). Accordingly, the static conductance values of the resistors in the resistors crossbar array are set to values equal to known coefficients of the DCT.

The method includes identifying a user group, generating a watch list of servers that control access to a new resource, and establishing a baseline behaviour for a client device based on a first access and a last access to one server in the watch list of servers during a time to live period. The method also includes adding the true network address and a correlated domain name to the baseline behaviour, retrieving a timestamp of an access by the client device to the network address, and flagging, as a violation, the access by the client device to the network address when the access is outside of a legitimate window around the baseline behaviour.

Abstract: Systems and methods described herein provide a centralized solution for interference mitigation that focuses on efficient spectrum management. Wireless Access Points (APs) collect interference measurements for wireless channels and generate corresponding interferer airtime estimates. The APs also determine Packet Error Rates (PERs) for wireless client devices currently being served via the channels by the APs. The APs send the interferer airtime measurements and the PERs to a centralized controller. If an interferer airtime estimate and a PER for a particular channel satisfy predefined threshold conditions, the controller modifies an allocation of wireless bandwidth for an AP that is currently using the channel and sends a message to the AP indicating how the allocation has been modified.

Abstract: Examples herein relate to developing an orchestration plan. Examples disclose the development of a representation of a set of services wherein each service relates to other services via different types of relationships. The examples apply a set of dependency rules for each type of relationship at each service within the set of services such that the application of the set of dependency rules creates inter-service dependencies between state transitions of the set of services. Based on the creation of the inter-service dependencies, the orchestration plan is developed which includes a sequenced order of the state transitions for the set of services.

The sampler can include a comparator comprising a resolver and a plurality of amplifiers coupled to the resolver. The plurality of amplifiers are to receive an input signal and one or more feedback signals, and the plurality of amplifiers are coupled to each other in parallel, thereby facilitating a summation of the input signal and the one or more feedback signals. The comparator is to generate an output based on the summation of the input signals and the one or more feedback signals. The sampler can further include an inverter to invert the output of the comparator. The inverted output of the inverter is sent to a tap-1 amplifier to generate a tap-1 feedback signal to be sent to the comparator at a next unit interval (UI).

Abstract: A component group table in a receiving node of a computer network stores access permission information for enabling the receiving node to validate an access request issued by a requesting node. An incoming access request at a receiving node includes a subnet ID/component ID (“SID/CID”) tuple. The receiving node selectively computes a component group table address for the requesting node according to an address mapping function determined by the value of at least one predetermined bit within the SID/CID tuple of the incoming access request. Using at least one bit in the SID/CID tuple enables the establishment of at least two address mapping regions in the component group table, such as separate regions for storage nodes and compute nodes in the network.

Abstract: Systems and methods are provided for increasing power save efficiency of stations within a wireless communications network. An access point (AP) can receive one or more session requests to establish a session from a station, each session request including one or more requested session parameters. The AP can set the session parameters to ensure that a session period of each requested session does not overlap two or more target beacon transmission time (TBTT) frames. The AP can merge two or more session periods of the one or more sessions by calculating a session period offset to align the end time of two or more session periods. Merging the two or more session periods minimizes the total wake time of the station.
