Abstract:
A method and apparatus for botnet analysis and visualization. Network traffic is filtered to compile a list of messages. The identified messages are tokenized, classified, and aggregated and changes in the frequency of tokenized messages are identified. A display of the tokenized messages is generated and displayed via a user interface. The user interface is configured to a allow a user to review data generated based on the filtered network traffic in order to detect potential botnet activity. User input may be used to adjust filtering and tokenization of the messages.
Abstract:
The various embodiments of the invention relate generally to computer software, computer program architecture, software development, and computer programming languages, and more specifically, to techniques for analyzing control flow in COBOL-sourced programs to facilitate optimized conversions to object-oriented program structures. For example, a compiler can include a global optimizer configured to analyze execution flow for a range of blocks of source code in the memory to determine flow-affected code. Also, the compiler can include a native code generator configured to generate native code based on representations of the native code as functions of the source code. The native code is configured to execute on a virtual machine.
Abstract:
Methods, systems, and computer-readable media for identifying potential threats on a network based on anomalous behavior in communication between endpoints are provided. Traffic data for a network is accumulated over some period of time. The traffic data is grouped by one or more keys, such as source IP address, and sets of metric values are calculated for the keys. A mixture distribution, such as a negative binomial mixture distribution, is fitted to each set of metric values, and outlying metric values are determined based on the mixture distribution(s). A list of outliers is then generated comprising key values having outlying metric values in one or more of the sets of metric values.
Abstract:
Systems and methods for efficiently detecting and coordinating step changes, trends, cycles, and bursts affecting lexical items within data streams are provided. Data streams can be sourced from documents that can optionally be labeled with metadata. Changes can be grouped across lexical and/or metavalue vocabularies to summarize the changes that are synchronous in time. The methods described herein can be applied either retrospectively to a corpus of data or in a streaming mode.
Abstract:
The invention concerns a method and system for detecting morphemes in a user's communication. The method may include recognizing a lattice of phone strings from the user's input communication, the lattice representing a distribution over the phone strings, and detecting morphemes in the user's input communication using the lattice. The morphemes may be acoustic and/or non-acoustic. The morphemes may represent any unit or sub-unit of communication including phones, diphones, phone-phrases, syllables, grammars, words, gestures, tablet strokes, body movements, mouse clicks, etc. The training speech may be verbal, non-verbal, a combination of verbal and non-verbal, or multimodal.
Abstract:
The present invention is directed to an apparatus and method for controllably adjusting a fluid delivery device. The device includes an electrochemical pump capable of transporting a fluid. A displaceable member is positioned between a pump product chamber and a reservoir, wherein the pump product chamber is capable of retaining water generated from the pump. The displaceable member is controllably displaced upon generation of water from the electrochemical pump and the reservoir contains the fluid that is delivered upon displacement of the displaceable member.
Abstract:
A mechanism for electrically connecting various electronic devices to a garment is provided. The mechanism has a sliding track adapted to support a variety of different electronic devices. The sliding track has one or more channels enabling elective electrical communication between at least one electronic device and a power source. The electronic device is adapted to be selectively supported by the sliding track such that the electronic device can slide along the sliding track. The mechanism has one or more channels having at least one conductive element disposed therein. The first conductive element is shaped to conform to one or more channels to provide an ideal electrical contact surface. The one or more channels are adapted to selectively enclose or seal the conductive element.
