Techniques may automatically detect bots or botnets running in a computer or other digital device by detecting command and control communications, called “call-backs,” from malicious code that has previously gained entry into the digital device. Callbacks are detected using a distributed approach employing one or more local analyzers and a central analyzer. The local analyzers capture packets of outbound communications, generate header signatures, and analyze the captured packets using various techniques. The techniques may include packet header signature matching against verified callback signatures, deep packet inspection. The central analyzer receives the header signatures and related header information from the local analyzers, may perform further analysis (for example, on-line host reputation analysis); determines using a heuristics analysis whether the signatures correspond to callbacks; and generally coordinates among the local analyzers.

The apparatus is an application software which implements the method by displaying the conventional price-time chart, calculating the relevant elements and overlaying the values on the chart bars, either in a static or real-time market setting.

Method for using seismic data from earthquakes to address the low frequency lacuna problem in traditional hydrocarbon exploration methods. Seismometers with frequency response Select Receivers of Desired Frequency Ranges and Design Survey Seismometer Configuration down to about 1 Hz are placed over a target subsurface region in an array with spacing suitable for hydrocarbon exploration (21).

A technique (and corresponding system) for controlling access to insertion opportunities in a multi-channel streaming media system is provided. The technique receives parameters for access to the insertion opportunities from multiple advertisers, such as desired audience viewership profile characteristics. The technique evaluates the received parameters to select which advertisers gain access to the insertion opportunities to place promotional content. The technique analyzes an audience of the placed promotional content and identifies which of the possible promotional content optimizes the value of the insertion opportunities or other maxima. Unlike traditional advertising in which advertisers pay per expected viewership, the technique may be arranged to charge advertisers only for a targeted audience that viewed the placed promotional content. The technique thus enables advertisers to access disparate insertion opportunities and to target an audience at lower cost without having to establish relationships with owners of insertion opportunities.

The invention is in the field of using a computer implemented method to calculate and provide recommendations for stock share investment timing. The process gathers price and volume data of listed firms from as many stock markets as implemented, only condition being that those markets price data are available over the Internet, in order to be able to automate the process. Analysing and calculation methods used within the process differ from those used in typical technical stock analyses in that the invention takes advantage of the known price history and uses statistical mathematics to categorize the current price to a recommended action: "sell', "buy' or "hold', while the most famous technical analysing methods typically try to predict the share price in the near future. The clear benefits of the process are that, after being set up properly, the process does not need human intervention, except in rare special cases, and furthermore, the calculated results are very easy to interpret even by persons without much experience in stock investing. Performance statistics clearly show that remarkable increase in profit of stock share investments can be gained by using the recommendations. The method has been implemented in a form of WWW-service and it is usable globally via the Internet. The method has been donated as StockMapper.

A thin film analysis system includes multi-technique analysis capability. Grazing incidence x-ray reflectometry (GXR) can be combined with x-ray fluorescence (XRF) using wavelength-dispersive x-ray spectrometry (WDX) detectors to obtain accurate thickness measurements with GXR and high-resolution composition measurements with XRF using WDX detectors. A single x-ray beam can simultaneously provide the reflected x-rays for GXR and excite the thin film to generate characteristic x-rays for XRF. XRF can be combined with electron microprobe analysis (EMP), enabling XRF for thicker films while allowing the use of the faster EMP for thinner films. The same x-ray detector(s) can be used for both XRF and EMP to minimize component count. EMP can be combined with GXR to obtain rapid composition analysis and accurate thickness measurements, with the two techniques performed simultaneously to maximize throughput.

Method for computing all-terminal reliability for arbitrarily interconnected networks such as the United States public switched telephone network. The method includes an efficient search algorithm to generate minimal cut sets for nonhierarchical networks directly from the network connectivity diagram. Efficiency of the search algorithm stems in part from its basis on only link failures. The method also includes a novel quantification scheme that likewise reduces computational effort associated with assessing network reliability based on traditional risk importance measures. Vast reductions in computational effort are realized since combinatorial expansion and subsequent Boolean reduction steps are eliminated through analysis of network segmentations using a technique of assuming node failures to occur on only one side of a break in the network, and repeating the technique for all minimal cut sets generated with the search algorithm. The method functions equally well for planar and non-planar networks.
