380 results about "Multiple indicator" patented technology

Multiple indicator models are a method of testing and correcting for errors made in measuring a concept or "latent construct.". Multiple indicators consist of two or more "alternative" measures of the same concept (e.g., two different ways of asking how satisfied you are with your life).

System, method, and computer program for creating and valuing financial instruments linked to real estate indices

A system, method and computer program for creating and valuing financial instruments (including but not limited to futures, forwards, call options, put options, swaps, “swaptions”, and “op-swaps”) linked to published real estate indices. The present invention will be referred to in this application as a real estate index linked financial instrument, and is defined as a financial instrument whose value changes based on movements in underlying indices based on real estate prices. These indices are published by sovereign governments, government-chartered agencies and departments (such as Fannie Mae, Freddie Mac, Office of Management and Budget, and the Treasury Department in the U.S.), non-governmental organizations, commercial banks, investment banks, realty agencies and many other organizations. The instruments can be written, with a published index number from any real estate index or indices as the initial value upon which the financial instrument's terms are based. The predicted future value of the real estate index or indices will change in response to market buy/sell demand based on investor expectations of the predicted future value of the real estate index or indices related to one or more real estate index linked financial instrument(s). Thus, the predicted future value of the index or indices will change in response to the market demand as investors offer to buy and/or sell real estate index linked financial instruments which will be listed on securities exchanges and electronic commerce networks (ECNs) as well as over the counter (OTC) and in private transactions. Each predicted future index value will change based on the investor expectation of how strong demand will be for the underlying real estate market upon which each index or indices are based. Thus, the present invention gives investors a means of taking or adjusting positions upon price movements in local, city, regional, state, national, or multinational/international real estate markets. It is important to note that real estate index linked financial instruments can be created either in standardized contract sizes that can be traded on futures, options or other securities exchanges, ECNs and/or OTC, or can be customized to meet the specifications of a transactional counterparty which wishes to speculate on movements in local, city, regional, state, national, or multinational/international real estate prices. Such instruments may also be created from a plurality of indices, thus allowing an investor to package movements from several different real estate indices into a single financial instrument. Such instruments may also involve a combination of real estate index linked financial instruments, either with each other or with other financial instruments in a combination containing at least one real estate index linked financial instrument.

Ship electric energy quality monitoring system

InactiveCN102565574ARealize power quality monitoringStrong anti-noise abilityElectrical testingQuality levelData acquisition
The invention belongs to an electric energy quality monitoring technology, particularly a ship electric energy quality monitoring system. The system comprises a data analysis evaluation subsystem and data acquisition processing subsystems distributed on each node. The data acquisition processing subsystems are used for acquiring three-phase voltage and current signals of a ship power grid in real time and providing the three-phase voltage and current signals for the data analysis evaluation subsystem by the Ethernet; the data analysis evaluation subsystem is used for completing calculation of steady-state electric energy quality indexes in an on-line mode and giving an electric energy quality comprehensive evaluation according to an index weight; the detection of transient-state electric energy quality perturbation parameters is completed in an off-time mode; the steady-state electric energy quality indexes comprise a voltage deviation, a frequency deviation, harmonic waves, three-phase unbalance, voltage fluctuation and flicker; and the transient-state electric energy quality perturbation parameters comprise short duration voltage variation, time varying harmonic waves and inter-harmonics. According to the system, all the nodes on the power grid can be simultaneously monitored, the factors influencing the electric energy quality can be analyzed by a plurality of indexes and the level of the electric energy quality of the power grid is timely known.

Multi-attribute drug comparison

A computer-implemented apparatus or method, or a software product, for generating a composite quantitative comparison of drug products based on multiple attributes of them. A set of name-attribute similarity scores are generated based on similarities among the names of selected target and reference drugs. A set of product-attribute similarity scores are generated based on similarities among product attributes of the selected target and reference drugs. A target drug confusability score is generated based on the confusability of the target drug as compared to a population of other drugs. The composite quantitative comparison is generated based on a composite of the name-attribute and product-attribute similarity scores, and the target confusability score. A set of one or more severity of confusion scores may also be included in the composite quantitative comparison. These scores are based on one or more indicators of the severity of the consequences to a patient of confusing the target and reference drugs so that, for example, the wrong drug is administered to the patient, or the correct drug is incorrectly administered. The name-attribute similarity scores may be generated based on orthographic, phonetic, and/or phonological analysis. The product-attribute similarity scores may be generated based on the drugs'strengths, indications, dosages, administration routes, manufacturers, pharmacological categories, storage requirements, colors, shapes, legal standing, trademark description, and/or other attributes. The composite quantitative comparison may include severity-weighted similarity scores or both similarity scores and severity of confusion scores. The severity of confusion indicators may include a therapeutic index and/or a contraindication index.

Comprehensive evaluation method for wireless sensor network performance

InactiveCN101867960AAvoid the problem of converging to local minimaIncrease training speedNetwork topologiesHigh level techniquesLine sensorCurse of dimensionality
The invention discloses a comprehensive evaluation method for wireless sensor network performance, relates to a least squares support vector regression (LSSVR)-based comprehensive evaluation method for wireless sensor network performance to comprehensively and reasonably evaluate running performance of small and medium-scale wireless sensor networks, and belongs to the technical field of wirelesssensors and network communication. The method is characterized by comprising the following four steps of: determining a network running performance index, determining an independent network running factor value by adopting a factor analysis method, establishing an LSSVR-based network performance comprehensive evaluation model, and performing LSSVR-based network performance comprehensive evaluation with low power consumption. The method solves the traditional problems of 'dimensionality curse' and 'over-learning' by skillfully using a kernel function, is quite suitable for the comprehensive evaluation of the small and medium-scale wireless sensor network performance with a plurality of indexes, assists an administrator in timely and accurately grasping the running condition and tendency ofthe WSN, and provides basis for network running evaluation and optimization.
