Programmable control micro-fluidic chip based on liquid-liquid electrowetting effect

The invention provides a programmable control micro-fluidic chip based on a liquid-liquid electrowetting effect. The programmable control micro-fluidic chip comprises a lower substrate, a drive electrode array, a lower substrate hydrophobic insulating layer, at least one liquid drop, an upper substrate hydrophobic layer, a conductive layer and an upper substrate from bottom to top, wherein cofferdams are added to the peripheries of the upper substrate and the lower substrate to form a closed cavity. The hydrophobic insulating layer is formed by a porous polymer film and a liquid capable of improving electric wettability and has the advantages of being good in electric wetting reversibility, reusable and resistant to voltage breakdown, high temperature and chemical reagents, the effect of the hydrophobic insulating layer is not affected after long-time storage, so that the service life of a device is prolonged, the efficiency of the device is improved, and the application range of the device is broadened; besides, the pressing mode of the drive electrode array can be programmed, therefore, operation processes such as rapid movement, combination, reaction and the like of different liquid drops are executed in different positions according to preset parameters.

Quick ideal condition quasi-synchronization paralleling method of hydro-generator

The invention relates to a quick ideal condition quasi-synchronization paralleling method of a hydro-generator, which is used for solving network incorporation speed and safety problem of generators.The technical scheme is as follows: the method regulates the voltage amplitude of the generator by regulating excitation current of the generator, leads the voltage amplitude to be equivalent to the voltage amplitude of a power system, utilizes a speed regulator of the generator set to regulate the voltage frequency of the generator, leads the voltage frequency to be equivalent to the voltage frequency of the power system, then overlaps a speed-increasing and angle-regulating signal or a speed-decreasing and angle-regulating signal with the corresponding strength on a signal controlled and outputted by the frequency difference PID in the speed regulator of the generator set according to the size of the phase angle difference between the voltage of the generator and the voltage of the powersystem, adjusts the size of the phase angle difference till the phase angle difference delta is 0, finally closes a circuit breaker of the generator, and leads the generator to be quickly incorporated into the power system under ideal parallel conditions. The method can quickly and safely incorporate the generator into the power system and not cause impacts on the generator, power equipment and the power system.

Organ geometry reconstruction method based on image volume element operation

InactiveCN103065358AEfficient Computing EvaluationGood application meaning3D modellingResearch resultReconstruction method
The invention provides an organ geometry reconstruction method based on the image volume element operation. The method comprises the steps of acquiring a location matrix of a volume element relative data set of a specified organ, resampling the location matrix according to accuracy requirements, generating a cuboid coordinate matrix by means of the volume element additive operation, and reconstructing organ geometry according to the cuboid coordinate matrix. The human organ geometry reconstruction method is capable of quickly merging volume elements to the maximum level by means of a volume element additive operation algorithm, keeping the original shape of an organ, completely describing the detailed structure of the interior of the organ, reserving and controlling point clouds on the periphery surface of the organ by flexibly and efficiently combining with sampling and the volume element operation, and therefore Monte Carlo geometric description of an associated organ is enabled to be easy. The research result of the organ geometry reconstruction method based on the image volume element operation is applicable to efficient calculation of different Monte Carlo programs and assessment of human body radiation absorbed doses, and has wide application significance in fields like radiation safety or medical physics.

Anatomic search and judgment method, system and distributed server system for map sites

InactiveCN102156749AAddressing Incomplete Coverage IssuesImplement multilingual searchSpecial data processing applicationsThe InternetDistributed servers
The invention provides an anatomic search and judgment method, an anatomic search and judgment system and an anatomic search and judgment distributed server system for map sites. The method comprises the following steps of: receiving a map site query request submitted by a user through a meta search engine portal server, and starting and managing a meta search task; constructing a uniform resource locator (URL) request according to the query request through a request distribution and response fused server, and adding the URL request into a request queue pool; distributing the URL request in the request queue pool to each proxy server; acquiring and returning response information returned by a specific search engine according to the distributed URL request by each proxy server; managing the request queue pool through the request distribution and response fused server, and establishing and managing a response queue pool according to the response information; and resolving the response information of the specific search engine so as to filter non map sites in the search results. By automatically searching and judging the Internet map sites, the problems of low result coverage, low accuracy and low working efficiency of the conventional method are solved.
