A method to authenticate a server to a client is provided, including in-band and out-of-band techniques. At least a first shared secret identifies a server path, including a plurality of pre-defined locations on a frame of reference (e.g. a grid). An authentication session is initiated upon receiving a client identifier at the server-side resources. A current session instance of the grid is presented to the client, populated with characters. The process includes sharing between the client and the server a challenge identifying a random subset of the plurality of predefined locations in the server path, and a response including characters that match the characters in the locations on the server path identified by the challenge. As a result, client is capable of verifying that the server has access to the first shared secret. Then a protocol is executed to authenticate the client to the server.

The invention relates to a method for carrying out a Two Way Ranging, preferably a Symmetrical Double-Sided Two Way Ranging, between a blind node whose position is unknown and to be determined and at least one reference or mobile node whose position is known in order to determine the location of the blind node, wherein the blind node and the reference or mobile node comprise wireless transceivers for transmitting and receiving radio signals. The invention is characterized in that the Symmetrical Double-Sided Two Way Ranging is initiated by the blind node.

Provided herein is a rack server including a rack, a plurality of system boards and a fan plate. The system boards are disposed within the rack, and each system board has a first wireless transceiver. The fan plate is also disposed within the rack, and the fan plate has a plurality of second transceivers, and the second transceivers are wirelessly connected to the first transceivers, respectively.

The invention discloses a continuous conveying type urban track traffic system which is characterized by comprising main conveying tracks established in city streets, connection conveying tracks established at street crossings, transitional conveyer belts established on sidewalks and track cars capable of bearing personnel and cargoes, wherein all the track cars are fore-and-aft connected in series to form an entirety which lacks beginning and ending and covers on the tracks; and transition belts arranged at fixed points on the streets can ensure that the personnel can realize stable transition between a walking state and a high-speed running state. The traffic system can achieve the aims of: (1) simultaneously conveying personnel and materials; (2) directly getting to both the destinations of the conveyed personnel and materials from the starting points; and (3) running continuously without any stop.

The invention discloses a method for cultivating a wood frog by breeding an oxya through an ecological fence, mainly comprising the following steps: (1) selecting a wood frog cultivation site; (2) building a fence; (3) collecting and storing oxya oocyst; (4) building a grassland for breeding the oxya; (5) building an oxya enlarged breeding room; and (6) taking the oxya as main insectivora to cultivate the wood frog. The method of the invention is a semi-naturalized cultivation model, does not change the ecological predation habit of the wood frog, avoids occurrence of epidemic pests and diseases while artificially breeding the wood frog, and has the advantages of simple basic facilities, simple and convenient operation, small investment, great income, no territorial restriction, easy popularization and implementation and the like.

The invention discloses a prefabricated fast assembled enclosure structure and a construction method thereof. The enclosure structure comprises enclosure plates, vertical columns and enclosure foundations; the vertical columns are fixed to the enclosure foundations, and each enclosure plate is fixed between every two connected vertical columns; the enclosure foundations comprise foundation platesand anchoring nails, and pre-embedded screw rods with the top stretching out are pre-embedded in the foundation plates; and reserved grooves are formed in the vertical columns, and the left ends and the right ends of the enclosure plates extend into the reserved grooves of the vertical columns and are fixed into the reserved grooves of the vertical columns. The pure dry connection mode is designed, wet operation is avoided, and construction is fast and convenient.

Provided is a noise remover of a PWM motor without a frequency control filter in a PWM control motor, and more particularly, includes a micom formed in the vehicle terminal and converting to and transmitting the frequency avoiding the radio frequency; a frequency filter for suppressing the noise converted by the micom; a motor part for transmitting the frequency that the frequency filter outputs to a vehicle motor, and operating the motor; and a pulse modulation/demodulation control part for controlling the rotation amount of the vehicle motor inside the motor part, which are divided roughly as four, and rotate a rotor of the motor part without noise by selectively applying the frequency which is not overlapped with radio frequency to a first FET, a second FET, a third FET, and a fourth FET.

The invention relates to infectious disease healthcare systems and methods. One embodiment of systems and processes according to various embodiments of the invention focuses on a method for providing a healthcare delivery franchise system. The method includes creating a not-for-profit franchisor entity. In addition, the method includes assessing a plurality of locations for a corresponding plurality of healthcare delivery clinics, wherein the demand for healthcare services from each healthcare delivery clinic and the revenue from each healthcare delivery clinic are estimated. Furthermore, the method includes based at least in part on the demand and revenue estimates, constructing at least a portion of the plurality of healthcare delivery clinics in corresponding locations, wherein the portion of the plurality of healthcare delivery clinics is associated with the not-for-profit franchisor entity.

The invention discloses a method for using a basement roof as a construction elevator foundation. The method is characterized by comprising the following steps of: a, reserving a screw hole in the basement roof according to the requirements of the installation position of the construction elevator; b, paving a mortar leveling layer on the basement roof; c, paving a rectangular steel plate above the mortar leveling layer; and d, installing a screw in the reserved hole, thereby finishing the arrangement of a foundation structure which takes the basement roof as a foundation of the construction elevator. The method for using the basement roof as the foundation of the construction elevator has the advantages that the foundation of the construction elevator is simple in structure and convenientto construct; the installation requirement and the safe operation requirement of the construction elevator are completely satisfied. The method is universal for construction elevators with the same model or the same fixed base, can be used in different projects in a turnover manner, and has the advantages of saving the manufacturing and dismounting outward transportation cost of an elevator concrete foundation, reducing the cost, saving energy, protecting the environment and reducing the engineering cost.

The invention provides a liquid pipeline silencing system based on underwater wide-low-frequency sound insulation metal-based metamaterial design. The liquid pipeline silencing system comprises a body structure, an inlet flange, an inlet cylinder through pipe, an outlet flange and an outlet cylinder through pipe, the two ends of the body structure are in sealed connection with the inlet cylinder through pipe and the outlet cylinder through pipe respectively; the liquid inlet end of the inlet cylinder through pipe is connected with the inlet flange and connected with a flange of a water inlet pipe of a pipeline through the inlet flange, and the liquid outlet end of the outlet cylinder through pipe is connected with an outlet flange and connected with a flange of a water outlet pipe of the pipeline through the outlet flange; and a cavity communicating with the inlet cylinder through pipe and the outlet cylinder through pipe is formed in the body structure, and two or four sound insulation material plates wrapped and sealed by rubber are placed in the cavity and tightly attached to the inner wall. The limitation of a traditional material is broken through, and wide and low frequency sound insulation of liquid in the pipeline is achieved through the special underwater wide and low frequency sound insulation metal-based metamaterial.
