摘要： Disclosed herein are methods and systems that apply a multi-layer Hidden Markov Model (HMM) for intrusion detection. The methods and systems employ a dimension reduction technique to extract only important features from network packet data and apply a decomposition algorithm to lower levels of data to construct lower level HMMs (representing partial solutions), which lower level HMMs are then combined to form a final, global solution. The multi-layer approach can be expanded beyond the exemplary case of 2 layers in order to capture multi-phase attacks over longer spans of time. A pyramid of HMMs can resolve disparate digital events and signatures across protocols and platforms to actionable information where lower layers identify discrete events (such as network scan) and higher layers identify new states which are the result of multi-phase events of the lower layers.

摘要： Disclosed is a content-based image retrieval (CBIR) system and related methods that serve as a diagnostic aid for diagnosing whether a dermoscopic image correlates to a skin cancer type. Systems and methods according to aspects of the invention use as a reference a set of images of pathologically confirmed benign or malignant past cases from a collection of different classes that are of high similarity to the unknown new case in question, along with their diagnostic profiles. Systems and methods according to aspects of the invention predict what class of skin cancer is associated with a particular patient skin lesion, and may be employed as a diagnostic aid for general practitioners and dermatologists.

摘要： Systems and methods are provided for reducing peak-to-average power ratio (“PAPR”) in an orthogonal frequency division multiplexing (“OFDM”) signal having reference tones by introducing modified pilot tones to cancel peaks in OFDM symbols in the OFDM signal array. The modified pilot tones are added to the original OFDM signal, which in turn conditions the OFDM symbols of the signal to effectively reduce the PAPR. Such systems and methods provide PAPR reduction for OFDM signals generated by an OFDM Signal Processor through the addition of tone reservation PAPR reduction methods, which use reserved tones such as pilot tones to improve PAPR. Such methods offer an advantage of improving the PAPR without introducing distortion to the signal.

摘要： A curtain enclosure formed from a flexible, non-permeable membrane is positioned adjacent to a section of riprap or similarly configured structure that has been installed along a shoreline. The curtain is stretched around rigid elongate posts and extends outward into the water from the edge of the riprap to create an enclosed containment area formed between the interior of the curtain and the edge of the riprap. The bottom of the curtain is weighted to sit along the bed of the water body and resist movement in that position. Once the curtain enclosure has been formed, larval bivalve organisms, such as oyster larvae, are poured into the curtain enclosure, and thereafter the curtain enclosure is maintained in that position for a period sufficient to promote attachment and growth of the larvae on the riprap.

摘要： Computer-implemented systems and methods are provided for the synchronization of data from asynchronous datasets to form a merged, synchronized data set, and more particularly to systems and methods for merging disparate and asynchronous data sets that include common dimensions, such as space and time dimensions, and more particularly space and time data relating to a driving simulation environment (such as driving simulator data and eye tracking data having disparate time data resolutions), to enable data extraction from and analysis of the merged, synchronized data set. A driving simulator system includes a driver interface having driving controls and a display and creates driving simulator data files for each driver of the driving simulator system having data entries that are captured at a first timing frequency. Likewise, an eye tracking system includes eye tracking cameras for tracking a driver's eye movements when using the driving simulator system and creates eye tracking data files for each driver of the driving simulator system having data entries that are captured at a second timing frequency that is different from the first timing frequency at which driving simulator data is captured. A driving behavior analysis computer is also provided that merges the asynchronous data embodied in each of the driving simulator data files and the eye tracking data files to form a single merged data file based upon an interpolation of data entries in those data files. The merged data files may then be further processed to enable extraction and analysis of the merged data in order to identify various driver behaviors.

摘要： Disclosed herein are computer-implement systems and methods for determining whether an electronic document transiting a computer network is safe for viewing and does not contain malicious code, and automatically routing or deleting such electronic document based on such determination, thus providing quick risk decisions relating to the electronic document using an objective, quantitative method. A search algorithm is employed to detect the presence of words or phrases in the subject electronic document that are possible threats to the computer network. Threat updates may be provided through publicly available threat database. A weight is added to the generated score that accounts for the time that the particular vulnerability has been in the subject threat database. Finally, a PNN is used to quickly and objectively classify the subject electronic document for acceptance, quarantine, or denial.

摘要： A method and apparatus for determining authenticity of objects using synchronous fluorescence spectroscopy (SFS). The fluorescent security feature of a flat object Q is identified under illumination with ultraviolet light. Then the security feature is illuminated by a beam of light at continuously varied excitation wavelength, while the intensity of emitted light (fluorescence) is recorded at the continuously varied, yet different emission wavelength. The difference between the wavelengths of emission and excitation is held constant, and the spectrum SFS(Q) is obtained. The same procedure is conducted with a known authentic (A) object, resulting in its synchronous fluorescence spectrum SFS(A). A comparison of SFS(Q) and SFS(A) is conducted. If SFS(Q) and SFS(A) are the same, the Q object is concluded to be authentic.

摘要： Disclosed is a system and method for predictive risk assessment and intervention including a risk assessment unit that receives survey data from a remotely connected survey device. The survey data comprises information about the social and cultural environment of one or more members of a risk population, including the member's perceptions of their social and environmental factors, the member's demographic data, and optionally publicly available data associated with the member's geographic environment. A predictive risk assessment unit analyzes perceived risk hierarchy inventories to generate a risk portfolio for each surveyed member of the population, which risk portfolio may include a risk predictive quotient profile for each such member assigning a numeric value indicating a likelihood of that member engaging in certain negative activities, a recommendation of interventions that are determined to reduce the likelihood of such member engaging in those negative activities, and preferably a record of success and/or failure of various interventions in reducing that risk. Intervention partners then administer the interventions to the surveyed members, record the success or failure of such intervention in preventing the identified dangerous behavior, and transmit an intervention effectiveness report to the predictive risk assessment unit. The predictive risk assessment unit may then modify and recalibrate the survey instrument and the associated recommended intervention products and tools to maximize the successes of interventions.
