47 results about "Set and setting" patented technology

Set and setting in psychedelic drug experiences means one's mindset (shortened to "set") and the physical and social environment (the setting) in which the user has the experience. This is especially relevant for psychedelic experiences in either a therapeutic or recreational context. According to the book How to Change Your Mind by Michael Pollan, the concept of set and setting was observed by the "Johnny Appleseed" of LSD, Al Hubbard visiting mushroom ceremonies in Mexico. The term was coined by Timothy Leary in 1961, and became widely accepted by researchers in psychedelic therapy. Norman Zinberg has also discussed this in Drug, Set, And Setting: The Basis for Controlled Intoxicant Use (1984).

Transformer fuzzy prudent reasoning fault diagnosis method based on cost sensitive learning

The invention discloses a transformer fuzzy prudent reasoning fault diagnosis method based on cost sensitive learning, and belongs to the field of transformer state evaluation and fault diagnosis. According to the invention, on the basis of acquiring a transformer state evaluation initial sample set and setting a cost sensitive initial matrix, firstly, by combining a Sigmoid multiattribute softening decision, a transformer fault diagnosis multi-class support vector matrix model is constructed; then, a support vector matrix is subjected to normalized ordered weighted averaging, and a fuzzy prudent membership degree weight is calculated; and finally, complementary confidence allocation and information fusion based on a PCR5 method are carried out on a weighed fuzzy prudent membership degree,and based on a confidence allocation fusion final value, transformer fault diagnosis decision determination is carried out. In such process, minimization of an error diagnosis sample number is used as an optimal object, a cost punishment element corresponding the cost sensitive matrix is iteratively corrected on the basis of the fuzzy prudent evidence reasoning process, and an online learning function of the fault diagnosis model is achieved.

Massive feature string sets matching method and apparatus

The present invention provides a massive feature string sets matching method and apparatus. The method comprises the steps of determining a length of a matched window according to a quantity of characters included in a feature string in the feature string set and setting an initial offset value for current to-be-matched data; performing offsetting and positioning on the current to-be-matched data by taking the initial offset value as a start point, acquiring a character block and using the character block as a first character block, wherein the character block takes the tail end of the matched window as a terminal point within the length of the matched window and has a length equal to a preset first length; when the first character block is a sub-feature string of the feature string set, acquiring a character block and using the character block as a second character block, wherein the character block takes an initial end of the matched window as an initial point within the length of the matched window and has a length equal to a preset second length; calculating a conversion value of the second character block, reading a bit vector corresponding to the conversion value and using the bit vector as a current matched vector; and performing feature string matching on the current to-be-matched data according to the current matched vector. According to the method, the space of a bit vector mask table is fully used, filtration passing rate is lowered, and matching is faster.

Emus transducer system as well as a method for producing linearly polarised transverse waves with variably predeterminable polarisation direction within a test specimen

Described are an EMUS transducer system as well as a method for producing linearly polarised transverse waves with variably predeterminable polarisation direction within a test specimen containing at least ferromagnetic material portions and with a test specimen surface with a magnetisation unit which is provided and set up for being arrangeable on the surface of the test specimen and for producing a magnetic field orientated parallel to the test specimen surface within the test specimen, as well as with at least one HF coil arrangement which is provided and set up for being arrangeable on the test specimen surface and for producing or detecting a HF field occurring overlaid with the magnetic field.
The invention stands out in that the magnetisation unit has at least three magnetisation bodies spatially distanced from one another, which are provided and set up to be placeable onto the test specimen surface and in each case to introduce magnetic field lines with a predeterminable magnetic flux into the test specimen, and in that means are provided, using which the magnetic flux of the magnetic field lines to be introduced into the test specimen, which emanate from at least one magnetisation body, can be changed in such a manner, so that the spatial direction of the magnetic field forming parallel to the test specimen surface within the test specimen can be changed in a predeterminable manner.
