摘要:
Systems and methods for automatically forecasting the future availability of one or more resources, such as Internet advertising opportunities, are described herein. In accordance with various embodiments, a forecasting model that accounts for event-driven resource availability is trained based both on historical supply data and calendar information specifying events and event duration. The trained forecasting model is then used to forecast the availability of resources at one or more specified future time periods. In accordance with certain embodiments, the forecasting model comprises a Gaussian process model that has an event-driven kernel as a covariance function.

Techniques are described herein for using an impression-trend technique to provide a display advertising supply forecast. A display advertising supply forecast is an estimate of a number of impressions, which are to occur in a future time period, that have specified attribute values. For example, the specified attribute values may be descriptive of impressions with respect to which an advertiser wishes to place ads. An impression-trend technique is a forecasting technique that uses trends regarding past impressions to forecast a number of future impressions that have specified attribute values. The past impressions include attribute values that are related to the specified attribute values.
摘要:
Methods, systems, and apparatuses for generating supply forecasts for advertisement impressions are provided. Supply forecasts for future advertisement inventory are enabled to be determined that match attribute values received from a requester in a query or “contract.” Such supply forecasts may be determined based on cumulative or non-cumulative supply forecast values, and may be determined based on time series of supply forecast values for individual impressions or for blocks of impressions.

Disclosed is a system to forecast a supply of online advertising demand contracts having day parting targets. The system may receive an online advertising demand contract having a flight duration and a day parting target. The received online advertising demand contract may be processed by converting the day parting target into an hour-of-week day parting target vector. If a first day of the flight duration would generate a conflict in view of the hour-of-week day parting target vector, then the system may generate a new first day contract for the first day of the flight duration.

A networking method of single frequency network in a TD-SCDMA system includes the steps of: (1) deciding a networking configuration scheme by a universal mobile telecommunications system terrestrial radio access network (UTRAN), (2) based on the decided networking configuration scheme, configuring an intra-frequency cell info list information element and an inter-frequency cell info list information element in system information and measurement control messages by the UTRAN, (3) transmitting signals over a servicing area by the UTRAN, and (4) receiving the system information and measurement control messages by a user equipment (UE) from the UTRAN, acquiring working mode configuration information of each frequency and each timeslot of a serving cell and neighboring cells, and judging whether there are duplicated cell information elements in the intra-frequency cell info list information element or the inter-frequency cell info list information element.

A solar energy collecting device includes a rotation axis to be mounted parallel to the earth's polar axis, a solar energy collector mounted for rotation around the rotation axis at a predetermined rotation speed, the solar energy collector defining a tilt angle with respect to the rotation axis, and a tilt angle adjustment mechanism for automatically and intermittently adjusting the tilt angle. Various configurations of the solar energy collector are possible, and the rotation speed may be one revolution per day or half a revolution per day depending on the solar energy collector configuration. Many drive modes are possible, including rotating continuously throughout a day or rotating during daylight hours and rotating backward or forward at night. The tilt angle adjustment mechanism includes a handle fixed to the solar energy collector and a tilt angle change guide.

Bubble stability within an optical switch is enhanced by controlling the expansion or movement of a bubble from a liquid-containing trench into available adjacent spacing. Typically, the adjacent spacing is formed between an optical waveguide substrate and a heater substrate, where the heater substrate includes a microheater for forming the bubble. The bubble enhancement is provided by intentionally altering surface features along at least one of the substrates.

In the field of imaging, various components may contribute to a loss in resolution at higher spatial frequencies, both horizontally and vertically. Higher spatial frequencies may occur at the edge of an image, where there may be a large transition in the signal output between adjacent pixels. To compensate, an edge enhancement method that produces overshoots in the transitions of the video image signal is used. One of the problems with the edge enhancement method is that the noise in the input signal may not be adequately suppressed. To suppress the background noise in the video image signal while still performing the desired edge enhancement function, biasing circuitry may be used to suppress the smaller transitions in the input signal. In particular, the biasing circuitry may be placed in the signal path between the output of a first delay line and the noninverting inputs of two of the signal amplifiers. In this manner, the smaller transitions in the signal which represent background noise may be suppressed, while the edges of the video image signal are still enhanced.
