Index for fixed income securities market

Вторник, 15 Апреля 2014 г. 19:28 + в цитатник

Abstract:


An index for a fixed income securities market may be determined based on price information regarding current activity taking place on one or more securities.



Description:


BACKGROUND OF THE INVENTION

The present invention generally relates to data processing systems for tracking and manipulating data corresponding to fixed income portfolios and, more particularly, to data processing methods and apparatus directed to the real time determination of selected fixed income indices for use in accurately gauging interest rate profiles in real time and managing a specifically delineated set of automated transactions relating thereto.

A sizable portion of investment vehicles available in today"s financial markets are universally characterized as fixed income securities. Exemplary fixed income securities will encompass government bonds, bills and notes auctioned at regular intervals by the U.S. and other foreign governments to finance governmental activities. These, of course, are some of many types of fixed income securities, others include corporate bonds, municipal bonds, etc. The common thread running between all fixed income securities is the payment of a set return to the investor over the life span of the security.

There are two forms of fixed income return to the investor. The first involves the provision of coupon payments at regular intervals, at the stated interest rate of the security. For example, a ten-year note may specify an 8% rate of interest on a $1,000 par value with coupons coming due twice each year for ten years. This translates to two $40 payments to the holder of the note for ten years with a final payment of $1040 (principal and interest). The other form of bond is called a zero coupon, or discount bond which provides no payment except for the final return of the face value of the bond at a specified date (e.g. ten years from issuance). The discount bond is sold at some fra ...

FIELD OF TECHNOLOGY

Aspects of the disclosure relate to managing an inventory of stocked items. In particular, the disclosure relates to managing different denominations of legal tender (bills and coins) in a retail banking business.

BACKGROUND

Retail banking is one example of an industry that involves maintenance of an inventory that includes a mix of multiple products. In some industries, those products are referred to using stock keeping units (SKUs).

In retail banking, customer"s are served at banking centers. A banking institution maintains an inventory of bills and coins that will meet the daily needs of the banking center"s customers. Seven denominations of cash are commonly required by customers: 1, 2, 5, 10, 20, 50 and 100 dollars. A cash vault may be used to hold excess inventory for the banking center and for multiple other banking centers. Each banking center, therefore, may have a cash vault that is designated to serve that banking center. (A cash vault is often located in the same geographic area as the banking centers that it serves.) The banking center orders cash from the cash vault (which may be referred to as the “Servicing Cash Vault”) according to a preset schedule. An order may require that cash be shipped from the banking center to the servicing cash vault (a “ship-out”). An order may require that cash be shipped from the servicin ...

Description:


FIELD OF THE INVENTION

Systems and methods provided by the invention relate to systems and methods for providing a discount. In particular, inventive systems and methods relate to systems and methods for providing a discount using a partner-issued currency or a combination of virtual currency and partner-issued currency.

BACKGROUND OF THE INVENTION

Providing a discounted retail price on a product or service is a time-honored method of increasing sales, increasing brand, product and service visibility and expanding the market for the product or service. However, providing a discount is a method to be used with care since frequent discounting may lead to a customer perception of decreased value such that customers are unwilling to pay the retail value under any circumstances.

A recent trend in discounting has been the association of a discount with “points,” “miles.” or other form of non-cash currency accumulated in order for the customer to realize a discount on a product or service. Such “mileage” or “point” accounts have the advantage of heightening customer loyalty to a particular product or service provider as well as providing the per ...

Computer-implemented systems and methods for defining events

Понедельник, 14 Апреля 2014 г. 18:51 + в цитатник

Abstract:


Computer-implemented systems and methods to process time-series data. As an example, a system and method can use a first data store to store time series data, and a second data store to store definitions of events. A dummy variable is generated when data from an event"s definition is applied to time series data.



Description:


TECHNICAL FIELD

The technology described in this patent document relates generally to the field of computer data modeling. More specifically, systems and methods are provided for modeling time-stamped data.

BACKGROUND

The effects of events on time-stamped data may be an important factor in creating an accurate computer model of the data, for example, to improve the predictive ability of the model. Examples of events that may affect time-stamped data include advertising campaigns, retail promotions, strikes, natural disasters, policy changes, a data recording error, etc.

The characteristics of an event may define the effect that an occurrence has on the time-stamped data and the duration of the occurrence. An event may include a single occurrence (e.g., a worker strike), multiple occurrences (e.g., a holiday), or irregular occurrences (e.g., new store openings.) Further, an occurrence may be on a fixed date or a relative date (e.g., an event may begin two weeks before Christmas.) In addition, an event may be a combination of occurrences (e.g., a retail sale that occurs over a holiday.) Thus, modeling events so that they increase the accuracy of a time series model can often be complicated.

SUMMARY

In accordance with the teachings provided herein, systems and methods for operation upon data processing devices are provided concerning the processing of time-series data. As an example, a system and method can use a first data store to store time series data, and a second data store to store definitions of events. A dummy variable is generated when dat ...

Method for estimating a used vehicle"s market value

Понедельник, 14 Апреля 2014 г. 09:25 + в цитатник

Abstract:


A method for estimating a used vehicle"s market value is disclosed. The method searches for a set of comparable vehicles in an existing historical database of used vehicles. Estimations of the used vehicles are established based on each comparable vehicle (neighbor) in the set of comparable vehicles by adjusting their resale value in accordance with the individual differences found between the neighbor(s) and the used vehicle whose market value is to be estimated/predicted (the target vehicle). Finally, a distance-weighted average of all such estimations is calculated to arrive at a market value estimation for the target vehicle.



Description:


TECHNICAL FIELD

The present invention relates to methods for estimating/predicting a used vehicle"s market value.

BACKGROUND ART

An accurate and efficient means for estimating/predicting used vehicle market value at the vehicle identification number (VIN) level using historical data has continually been pursued. Especially when large numbers of vehicles are involved, small errors in estimating used vehicle market value could translate large monetary losses.

Conventionally, the value of a used vehicle is estimated by performing database queries on vehicles having similar features, options and content and having known market values. Once the closest used vehicles are located, the estimated market value is determined by finding the average vehicle market value of the closest used vehicles located.

However, this conventional approach fails to deliver accurate estimations of vehicle market value because of its inability to adjust for vehicle differences at the VIN level. Moreover, many times the inconsistency in the criteria for selecting similar used vehicles further skews the market value estimate. Other methods include performing linear regression on historical vehicle data to determine relative market value and sensitivity of vehicle con ...

Source-dependent text-to-speech system

Понедельник, 14 Апреля 2014 г. 09:25 + в цитатник

Abstract:


A method of generating speech from text messages includes determining a speech feature vector for a voice associated with a source of a text message, and comparing the speech feature vector to speaker models. The method also includes selecting one of the speaker models as a preferred match for the voice based on the comparison, and generating speech from the text message based on the selected speaker model.



Description:


TECHNICAL FIELD OF THE INVENTION

This invention relates in general to text-to-speech systems, and more particularly to a source-dependent text-to-speech system.

BACKGROUND OF THE INVENTION

Text-to-speech (TTS) systems provide versatility in telecommunications networks. TTS systems produce audible speech from text messages, such as email, instant messages, or other suitable text. One drawback of TTS systems is that the voice produced by the TTS system is often generic and not associated with the particular source providing the message. For example, a text-to-speech system may produce a male voice no matter who the person sending the message is, making it difficult to tell whether a particular message came from a man or a woman.

SUMMARY OF THE INVENTION

In accordance with the present invention, a text-to-speech system provides a source-dependent rendering of text messages in a voice similar to the person providing the message. This increases the ability of a user of TTS systems to determine the source of a text message by associating the message with the sound of a particular voice. In particular, certain embodiments of the present invention provide a source-dependent TTS system.

In accordance with one embodiment of the present invention, a method of generating speech from text messages includes determining a speech feature vector for a voice associated with a source of a text message, and comparing the speech feature vector to speaker models. The metho ...

Abstract:


A sensor readout includes a selector circuit, a predictor circuit, and a select controller. The selector circuit receives a plurality of actual sensor inputs. Each actual sensor input is provided to the selector circuit along a corresponding channel. The selector circuit also passes a selected sensor input. The predictor circuit receives the selected sensor input into a signal history and generates predicted sensor inputs. The select controller receives the predicted sensor inputs, determines which of the predicted sensor inputs is most changed from the actual sensor inputs as the most changed input, and directs the selector circuit to pass a next signal on a the channel having the most changed input.



Description:


BACKGROUND

This disclosure relates to angular sensors or field sensors used for angular measurements and their corresponding sensor readouts. More particularly, this disclosure relates to an angular sensor readout that predicts the next angular measurement to more quickly determine the location of the next angular measurement along a trajectory.

Recently, sensor readouts have begun to include predictors to determine the next likely output from the sensor. This can help to prepare the readout for the next actual output from the sensor and thus help to speed up and use less power than in previous readouts. A predictive sensor readout generally includes a sampling circuit configured to receive and over-sample previously digitized samples of signals previously input from a sensor. A predictor circuit, or predictor engine, receives the over-sampled previously digitized samples into a signal history and to generate a predicted input from the sensor based on the signal history. A preset circuit presets the sampling circuit to receive the predicted input from the sensor prior to sampling an actual input from the sensor.

Predictor circuits work more precisely the higher the oversampling ...

Self-calibrated azimuth and attitude accuracy enhancing method and system (SAAAEMS)

Воскресенье, 13 Апреля 2014 г. 11:24 + в цитатник

Abstract:


A method and system for Self-calibrated Azimuth and Attitude Accuracy Enhancing are disclosed, wherein SAAAEMS approach is based on fully auto-calibration self-contained INS principles, not depending on magnetometers for azimuth/heading determination, and thus the system outputs and performance are not affected by the environmental magnetic fields. In order to reduce the system size and cost, this new innovative methods and algorithms are used for SAAAEMS system configuration and integration. Compared to a conventional INS for gyrocompassing, AGNC"s approach uses a smaller number of high accuracy sensors: SAAAEMS uses only one 2-axis high accuracy gyro (for example, one DTG) instead of 3-axis; the third axis gyro is a MEMS gyro. It uses only 2 high accuracy accelerometers instead of 3, since the two accelerometers are used only for gyrocompassing not for navigation. These two changes to the conventional INS system configuration remarkably reduce the whole system size and cost. SAAAEMS, uses dynamic gyrocompassing processing for isolation of Base motion disturbance/interference and vibration. SAAAEMS provides a method and system for using automatic methods for system calibration.

Systems and methods for baseline correction using non-linear normalization

Суббота, 12 Апреля 2014 г. 17:49 + в цитатник

Abstract:


Systems and methods for normalizing detected emission data collected in real-time polymerase chain reaction (RT-PCR) and other reactions, are provided. In some embodiments, a sample plate can be loaded with a fluorescent dye and subjected to a real-time PCR reaction. During the initial cycles, detected emissions that correspond to the background signal contributed by the plate, buffer, and other non-reactant pieces of the reaction system and chemistry can be identified. The raw emission data can be normalized by dividing the emission data by the identified baseline signal. According to various embodiments, the normalized amplification profile can normalize to an initial value of 1, because the actual signal emerges from the baseline at the point exponential growth begins. A normalized amplification profile based on a ratio to the baseline can create a more uniformly scaled amplification curve across different samples, filters, wells, dyes, or machines.



Description:


BACKGROUND

Real-time polymerase chain reaction (RT-PCR) technology, as presently practiced, relies upon the accurate detection of fluorescent emission signals above an initial baseline. The baseline signal can represent a combination of spurious or unwanted signal contributions such as the residual fluorescence contributed by the plastic or other material of a sample plate, the fluorescence of a running buffer or other non-reactant liquid material, noise in the optical detector or detection electronics, or some other source of background signal noise or detection floor that is not a product of the amplification or other reaction. In various known RT-PCR implementations, better accuracy in the detection of the amplification signal, and hence original sample quantity, is frequently sought by characterizing the baseline floor over the first few PCR cycles, or pre-signal detection cycles, and then subtracting the baseline from the detected emi ...

Abstract:


A transcript mapping method according to an embodiment of the invention is described hereinafter and combines short tag based (SAGE and MPSS) efficiency with the accuracy of full-length cDNA (flcDNA) for comprehensive characterization of transcriptomes. This method is also referred to as Gene Identification Signature (GIS) analysis. In this method, 5′ and 3′ terminal tags are obtained from a transcript and the terminal tags are for identifying 5′ and 3′ sites located on a genome sequence. Further, occurring segments and thus feasible gene locations are identified along the genome sequence after the 5′ and 3′ sites are identified. A data structure is also generated for indexing the genome sequence so that the terminal tags can be mapped to the genome sequence.



Description:


FIELD OF INVENTION

The present invention relates generally to a transcript mapping method. In particular, the invention relates to a transcript mapping method for mapping from a transcript to a compressed suffix array indexed genome sequence.

BACKGROUND

Since the completion of the genome sequences for human and several other organisms, attention has been drawn towards annotation of genomes for functional elements including gene coding transcript units and regulatory cis-acting elements that modulate gene expression levels.

Currently there are three main approaches for genome annotation. The first approach uses existing transcript data to identify gene-coding regions in the genomes, the second approach uses computational algorithms to statistically predict genes and regulatory elements and the third approach compares genomic sequences from other vertebrates for conserved regions based on the view that functional elements in genomes are conserved during evolution.

Despite considerable success, these approaches are unsatisfactory for determining the complete and precise content of all functional el ...

Device and method for controlling ignition timing of internal combustion engine

Суббота, 12 Апреля 2014 г. 09:08 + в цитатник

Abstract:


An engine ECU executes a program that includes: calculating a median value and a standard deviation based on a calculated value based on the detected vibration of the engine; and subtracting a product of the standard deviation and a coefficient from the median value to calculate a magnitude of mechanical vibration specific to the engine. Knocking determination is carried out by comparing a knock magnitude calculated by dividing the magnitude value of the peak magnitude of the detected vibration of the engine by the magnitude of mechanical vibration specific to the engine with a predetermined determination value. Based on the knocking determination result, ignition timing of the engine is controlled.



Description:


TECHNICAL FIELD

The present invention relates to device and method for controlling ignition timing of an internal combustion engine, and particularly to a technique of controlling ignition timing based on whether knocking is present or absent.

BACKGROUND ART

Conventionally, techniques of determining whether knocking is present or absent in an combustion engine are known. For example, there is a technique of determining whether knocking is present or absent based on whether or not magnitude of vibration detected in an internal combustion engine is greater than a knocking determination value. The magnitude of vibration detected by the technique includes mechanical vibration of the internal combustion engine itself. The mechanical vibration of the internal combustion engine itself varies by the speed of the internal combustion engine. Accordingly, in order to improve the precision of knocking determination, it is necessary to carry out knocking determination taking into account of the mechanical vibration of the internal engine itself which varies by the speed of the internal combustion engine.

The present invention relates to a method for determining the applied torque on a steering system of a motor vehicle.

BRIEF DESCRIPTION OF RELATED ART

With a conventional steering system, steerable wheels are steered by a driver via an actuation unit, more preferably through twisting a steering wheel. The rotating of the steering wheel causes a displacement of a rack which in turn pivots the wheels. In power steerings the steering movement of the driver is supported through an additional electric motor. Here, the steering support is generally performed through characteristic-controlled or regulated systems where the steering support is applied as a function of the vehicle speed.

Electric power steering systems generally utilize a separate torque sensor assigned to the steering system for measuring the steering moment applied to the steering wheel by the driver. This torque sensor usually serves exclusively for measuring the torque but can also be combined with an angle-of-rotation-sensor. In addition to this, indirect torque measurement is also known where, via the twisting angle of two parts of the steering column or the steering gear connected with an elastic element designed for this purpose, such as a torsion bar, the torque is determined. Also known is a direct torque measurement on a component of the steering train for example according to a magneto-elastic principle. However, in each case a mo ...
