69 results about "Functional response" patented technology

A functional response in ecology is the intake rate of a consumer as a function of food density (the amount of food available in a given ecotope). It is associated with the numerical response, which is the reproduction rate of a consumer as a function of food density. Following C. S. Holling, functional responses are generally classified into three types, which are called Holling's type I, II, and III.

Method and system for cyber-security vulnerability detection and compliance measurement (CDCM)

Method and System for Cyber-Security Vulnerability Detection and Compliance Measurement (CDCM) provides any entity, organization or individual with access to or possession of sensitive, confidential or secret information, defined as “protected information,” in digital format that is received, processed, stored or distributed by a computer, computer system or digital processing equipment with the capability to detect and respond to cyber security vulnerabilities and to measure compliance with cyber-security requirements as established by the Federal Security Information Management Act (FISMA) for the security of protected information and certain additional related desirable or mandatory cyber-security requirements. In one sample embodiment of the invention, the method utilizes a damage assessment function; a security assessment function; a security plan or planning function; a training management function; a response management function; a cyber-security management function; a scoring measurement function; and a review and analysis function; to establish a quantifiable and definitive numerical measurement of the relative compliance of a specific processing system, at a specific point in time, to a defined and established threshold value of performance, or compliance acceptance, and to provide, assemble and be capable of archiving the supporting parameters, status, states and analysis that is specifically associated with the numerical value which represents the specific processing system's state of compliance at the specified time and to utilize various intermediate values and parameters to manage and enhance the performance of the specific system thereby improving the systems compliance score and numerical performance measurement value.

The invention relates to a method for recognizing a function response signal under function nuclear magnetic resonance scan, comprising the following steps of: (1) obtaining task-state data and resting-state data by utilizing a nuclear magnetic resonance apparatus, processing the data in space and time by utilizing a function nuclear magnetic resonance analysis software SPM (statistical parametric mapping) to obtain a data set; (2)reducing the dimensionality of the task-state data and the resting-state data by utilizing a current principal component analysis PCA method, conserving main information, i.e. conserving the eigenvectors of information energy of over 90 percent of the data, reestablishing data, and then respectively extracting independent components of the two kinds of data including a machine noise signal component, a non-neurogenic physiological noise component and a neurogenic function signal response component by utilizing an independent component analysis ICA method in current time domain; (3) finding out the range of the function signal component by carrying out corresponding traversal among independent components of the two kinds of data to obtain a data set containing the function signal component; and (4) carrying out spectral analysis on every signal in the data set, eliminating components without obvious energy peak values in frequency domain, and selecting a principal component from rest components which is the principal function respond signal.
