Methods are disclosed for encoding latitude/longitude coordinates within a URL in a relatively compact form. The method includes converting latitude and longitude coordinates from floating-point numbers to non-negative integers. A set of base-N string representations are generated for the integers (N represents the number of characters in an implementation-defined character set being utilized). The latitude string and longitude string are then concatenated to yield a single output string. The output string is utilized as a geographic indicator with a URL.

In the present invention, an apparatus for behavior analysis and method thereof is provided. In this apparatus, each behavior is analyzed and has its corresponding posture sequence through a triangulation-based method of triangulating the different triangle meshes. The two important posture features, the skeleton feature and the centroid context, are extracted and complementary to each other. The outstanding ability of posture classification can generate a set of key postures for coding a behavior sequence to a set of symbols. Then, based on the string representation, a novel string matching scheme is proposed to analyze different human behaviors even though they have different scaling changes. The proposed method of the present invention has been proved robust, accurate, and powerful especially in human behavior analysis.

A system and method for comparing a text image and a character string are provided. The method includes embedding a character string into a vectorial space by extracting a set of features from the character string and generating a character string representation based on the extracted features, such as a spatial pyramid bag of characters (SPBOC) representation. A text image is embedded into a vectorial space by extracting a set of features from the text image and generating a text image representation based on the text image extracted features. A compatibility between the text image representation and the character string representation is computed, which includes computing a function of the text image representation and character string representation.

Systems and methods for providing a binary representation of a web page. A server may compile a source page, such as a hypertext markup language (“HTML”) document, to create a compiled representation of the source page. Creation of a compiled representation may include generating a document object model (“DOM”) for the content associated with the source page. The compiled page may be transmitted to a client as a random-access file or flat file, where the data is encoded in one or more data types other than a string representation. The client may receive the compiled page and load the compiled page directly as a DOM for the page without the need to parse HTML text strings. The server and client may reconcile the data format of the compiled page, such as by exchanging or verifying a compiler dictionary associated with the page.

A system and method for comparing a text image with or without a wildcard character and a character string are provided. The method includes embedding a character string into a vectorial space by extracting a set of features from the character string and generating a character string representation based on the extracted features, such as a spatial pyramid bag of characters (SPBOC) representation. A text image is embedded into a vectorial space by extracting a set of features from the text image and generating a text image representation based on the text image extracted features. A similarity between the text image representation and the character string representation is computed, which includes computing a function of the text image representation and character string representation.

A string instrument educational device implemented on a computer having a touch screen (100) that causes a note representation of a musical note (140) to appear and travel along a string representation (having locations to depress to cause the string representation to play a corresponding plurality of notes) to a target area (150) a time interval before the note is to be played. The note representation (140) preferably reacts when the musical note has been correctly played by the user touching the touch screen (100) at the correct location when the note representation reaches the target area (150). The note representation preferably reflects which location must be touched to correctly play the note.

The invention discloses a behavior segmentation method based on human body motion capture data character string representation. The method comprises steps of S1, taking human body motion capture data as multiple high dimension discrete data points, and calculating each Euclidean distance between data points; S2, performing clustering through a cluster method based on the local density and the relative distance of each data point to obtain a category to which the data point belongs, and using different characters for representing different categories; S3, reordering the characters according to time sequences of data corresponding to the characters to obtain character strings, and merging the same characters adjacent in time sequence of the character strings to form character groups, wherein each character group forms a behavior string; and S4, segmenting a whole behavior formed by the human body motion capture data according to the behavior strings, and extracting the motion period of each single behavior after segmentation. The technical scheme of the invention is good in accuracy, and excellent in applicability, validity and non-supervision.

Multi-byte compressed string representation embodiments define a String class control field identifying compression as enabled/disabled, and another control field, identifying a decompressed string created when compression enabled. On pattern matching by a compiler, noping tests based on null setting of stringCompressionFlag and registering a class loading assumption on a nop location. When arguments to a String class constructor are not compressible, a decompressed String is created and stringCompressionFlag initialized. Endian-aware helper methods for reading/writing byte and character values and helper methods for widening, narrowing, truncation, conversion and masking are defined. Enhanced String class constructors, when characters are not compressible, create a decompressed String, and initialize stringCompressionFlag triggering class load assumptions, overwriting all nopable patch points. A String object sign bit is set to one for decompressed strings when compression enabled, and masking/testing this flag bit is noped using stringCompressionFlag and associated class load assumption. Alternative package protected string constructors and operations are provided. Checking a predetermined location to determine whether supplied arguments to a String class constructor are compressible is performed.

A computer implemented method of and apparatus for printing values in a fixed number of column spaces using Java is described. A value desired to be formatted to a predetermined length string and an indexed lookup table having predetermined formatted string entries are used. An index based on the number of characters needed to represent the value is calculated and then used to locate a desired length formatted string entry in the lookup table. The desired length formatted string entry is then combined with a string representation of the value to form a predetermined length string.

Methods for creating a hybrid string representations include receiving string information as input; parsing the string information to produce one or more string components; determining string components that may be represented concretely by comparing the one or more components to a set of known concretizations; abstracting all string components that could not be represented concretely; and creating a hybrid string representation that includes at least one concrete string component and at least one abstracted string component.

A computer-implemented method, computer system, and computer program product are directed to improving computer security of a device using value based information flow tracking. Embodiments automatically capture raw data values from a data source of the device and store in memory the captured raw data values in a collection of sensitive data. Embodiments determine whether computed values of functions of a data flow are included in the collection of sensitive data. Based upon the determining, embodiments prevent values of the collection of sensitive data from being transmitted from a sink of the device. Embodiments may determine whether string representations of computed operand and return values of numerical or arithmetic operations of the functions of the data flow are included in the collection of sensitive data.

The invention discloses a method and device for encoding a chromosome based on an intelligent scheduling. The method comprises the steps that product tasks are obtained, wherein at least one product task comprises at least two types of working procedure tasks; the product tasks are encoded by adopting a double-layer encoding rule based on the working procedure tasks to obtain a chromosome code string representing any preset working procedure job sequence.
