Abstract: A touch sensing method and a serial manipulator using the same are disclosed. A serial manipulator using the method may detect and localize external torques by obtaining a torque value of each joint of a serial manipulator through a torque sensor at the joint; obtaining a preset joint angle of each joint from the serial manipulator; calculating a Jacobian matrices of the serial manipulator based on the joint angle of the joints; estimating joint torques of the serial manipulator based on the torque value of each joint and the Jacobian matrices; calculating an error between the torque value of each joint and the estimated joint torque corresponding to the joint; and determining a link of the serial manipulator that is connected to the joint with the minimum calculated error as having been touched.

Abstract: A method for searching for multiple sub-strings of an original text is provided. A search query is received, wherein the search query includes a plurality of sub-strings. A hash array is allocated. The hash array has a size based, at least in part, on the plurality of sub-strings and an original text. The hash array is populated with a plurality of hash values, wherein the plurality of hash values are generated using a rolling hash function, and wherein each of the plurality of hash values corresponds to a portion of the original text. A plurality of sub-string values are computed based on the plurality of sub-strings. Each of the plurality of sub-strings are determined to occur in the original text based, at least in part, on searching the hash array for the plurality of sub-string values.

Abstract: Techniques are described for detecting anomalous behavior in program execution. In one example, a method includes logging occurrence of one or more key run time events during execution of a program. Each key run time event has a corresponding key run time event data structure associated with the program, and logging includes storing records associated with the key run time events, wherein each record is based on the key run time event data structure associated with the key run time event. The method further includes analyzing the records to determine if a current pattern of key run time events associated with the program during execution matches an expected pattern of key run time events and generating a security alert if the current pattern of key run time events does not match the expected pattern of key run time events for the program.

Abstract: Methods and systems for cross-language program execution include setting a signature of a second programming language in a first program that is written in a first programming language. A second program that is written in the second programming language is called from the first program, such that the second program omits checks to verify a runtime environment for the second programming language based on the presence of the signature.

Abstract: The present invention provides compositions, and related kits and methods, for formation of hydrogels. The compositions comprise one or more chemically crosslinkable agents dissolved in an aqueous solution to form a precursor solution. The chemically crosslinkable agents useful in the present invention are selected from polymers modified with a molecule selected from acrylate, maleimide, vinylsulfone, N-hydroxysuccinimide, aldehyde, ketone, carbodiimide, carbonate, iodoacetyl, mercaptonicotinamide, quinone, thiol, amine, and combinations thereof. The precursor solution is characterized as being in an aqueous form at a non-physiologic physical-chemical condition and undergoing gelation when in contact with another fluid or body at a physiologic physical-chemical condition.

Abstract: Techniques are described for parsing a software program using parallel processing. In one example, a method includes tokenizing input source text to form a token stream having a plurality of tokens, partitioning the token stream into partitions by division and by statement, parsing two or more of the partitions in parallel, and traversing the common symbol dictionary to detect semantic errors. Partitioning includes storing an entry representing each partition in a partition table, including scanning the token stream in reverse starting at the end of each division. Parsing the partitions in parallel includes building, for each statement partition, an annotated syntax tree (AST) to represent the statement, storing, for each symbol, an entry in a common symbol dictionary, and generating error messages corresponding to syntax errors detected while parsing the partitions.
