Abstract: Denial-of-service attacks are prevented or mitigated in a cloud compute environment, such as a multi-tenant, collaborative SaaS system. This is achieved by providing a mechanism by which characterization of “legitimate” behavior is defined for tenant applications or application classes, preferably along with actions to be taken in the event a request to execute an application is anticipated to exceed defined workflow limits. A set of application profiles are generated. Typically, a profile comprises information, such as a request defined by one or more request variables, one or more “constraints,” one or more “request mappings,” and one or more “actions.” A constraint is a maximum permitted workload for the application. A request mapping maps a request variable to the constraint, either directly or indirectly. The profile information defines how a request is mapped to a workload to determine whether the request is in policy or, if not, what action to take.

Abstract: Denial-of-service attacks are prevented or mitigated in a cloud compute environment, such as a multi-tenant, collaborative SaaS system. This is achieved by providing a mechanism by which characterization of “legitimate” behavior is defined for accessor classes, preferably along with actions to be taken in the event an accessor exceeds those limits. A set of accessor “usage profiles” are generated. Typically, a profile comprises information, such as a “request time window,” one or more “constraints,” and one or more “actions.” A request time window defines a time period over which request usage is accumulated and over which constraints are applied. A constraint may be of various types (e.g., number of transactions, defined resource usage limits, etc.) to be applied for the usage monitoring An action defines how the system will respond if a particular constraint is triggered. By applying the constraints to accessor requests, over-utilization of compute resources is enabled.

Abstract: A system and method for producing a binaural and localized audio signal to a user is provided. A signal processing method is provided for delivering spatialized sound in various ways using highly optimized inverse filters to deliver narrow localized beams of sound from the included speaker array. The inventive method can be used to provide private listening areas in a public space and provide spatialization of source material for a single user to create a virtual surround sound effect. In a binaural mode, a speaker array provides two targeted beams aimed towards the primary user's ears—one discrete beam for the left ear and one discrete beam for the right ear. In a privacy mode, a privacy zone could be created in which a primary audio beam would deliver a signal of interest to the user while secondary beams would be aimed at different angles to provide a masking noise.

Abstract: A method and device for explosives identification bombards a sample with neutrons the energy of which is to the positron activation energy of nitrogen and to the required energy for a neutron proton nuclear reaction of neutrons with 16O to 16N. Electron positron annihilation radiation emitted by the sample due to the neutron bombardment is then detected as a function of time. The respective concentration and the concentration ratio of oxygen and nitrogen in the sample is determined from the time dependency of the annihilation radiation, and the explosive is identified by the comparison of the concentration ratios of the specific concentrations of oxygen and nitrogen with the corresponding substance ratios of known explosives. By radiation with neutrons at the same time radionuclides 13N are created from the nitrogen contained and 16N from the oxygen contained, the decay of which generates electron positron annihilation radiation with characteristic half-lives.
