Methods, systems, and computer program products for facilitating user interaction with customer relationship management, auction, and search engine software using conjoint analysis

Methods, systems, and computer program products for combining conjoint analysis with customer relationship management software, search engine software, and auction software are disclosed. According to one method, conjoint analysis is used to facilitate user interaction with a search engine. According to the method, search keywords are received as a user and treated as attributes by a conjoint analysis application. The conjoint analysis application presents the user with paired trade-off questions regarding the search keywords. Conjoint analysis is performed based on user responses to the questions. Based on the user's responses to the questions, relative importance weightings are computed for keywords. The keywords and the relative importance weightings are input to a search engine. The search is performed using the keywords. Results to be output to the user are selected based on occurrences of the keywords in the search results and the relative importance weightings.

Electrified railroad through power supply system without split phase

InactiveCN101746282AReduce negative sequence and reactive powerImprove power qualityPower supply linesPower inverterSingle phase
The invention discloses an electrified railroad through power supply system without split phase. The electrified railroad through power supply system is characterized in that a traction transformer in a traction substation is a three-phase-two-phase balancing transformer, the three phases of the primary side of the three-phase-two-phase balancing transformer of each traction transformer are correspondingly connected with the three phases of the same public power grid, a power flow controller is connected between the two output phases of the three-phase-two-phase balancing transformer, and one of the two output phases supplies power to a locomotive; each traction transformer uses the same phase to supply power to the locomotive; and the power flow controller consists of a first single-phase isolating transformer, a first voltage source inverter, a direct-current coupling capacitor, a second voltage source inverter and a second single-phase isolating transformer which are connected in turn. The system can implement railroad full-line connection in the same power supply network, and has no split phase through power supply so as to simplify the engineering design and save the investment and maintenance expense; and the system ensures the high-speed, stable and safe operation of the train, and is particularly suitable for high-speed and heavy haul railways.

Optical fiber cladding SPR sensor, and use method and manufacture method thereof

The invention belongs to the technical field of optical fiber sensing, and mainly relates to an optical fiber cladding SPR sensor, and a use method and a manufacture method thereof. The invention aimsat providing an optical fiber cladding SPR sensor, and solves a problem that the conventional optical fiber SPR sensor is difficult to process and manufacture, evanescent waves are hard to obtain andcost is high. According to the invention, a normal optical fiber is subjected to core shift welding on an optical fiber welding machine, light in a fiber core is leaked in the cladding, when the light arrives at an interface of the cladding and the air, the evanescent waves can be leaked from the cladding, a nanoscale gold film is formed at the interface of the cladding and the air through plating, thus, an SPR effect happens at the outside of the cladding, and complex processing technologies are avoided; compared with the conventional optical fiber SPR sensor, the optical fiber cladding SPRsensor provided by the invention has the advantages of being small in volume, novel in structure and less difficult to manufacture, and so on, and is widely researched and applied in the fields of bio-pharmaceuticals, food safety inspection and chemical detection.

Holding apparatus for substrate cassette and storage method for the same

A holding apparatus for a substrate cassette include a support base for holding the cassette with substrates. A tilting device is fixed to the support base for allowing the support base to rotate about a horizontal axis from a horizontal position, wherein top surfaces of the substrates are arranged upwardly, to an over vertical position, wherein the top surfaces of the substrates are arranged downwardly, by rotating the support base over 90 degrees. A storage method for a substrate cassette includes steps of storing a substrate in the cassette for substrates almost horizontally, fixing a cassette on a support base, and rotating the support base around a rotary shaft so that the substrate may rotate to the angle beyond 90 degrees.

A portable combined zero setting high precision laser large working distance auto-collimation device and method

The invention relates to the field of precision measurement technology and the field of optical engineering and in particular relates to a portable combined zero setting high precision laser large working distance auto-collimation device and method. The device comprises a light source, a collimating mirror, a reflector, and a feedback imaging system. The method makes reflected light beams return to the image plane center of the feedback imaging system by adjusting the reflector and obtains the angle change of the surface of a measured object by means of an angle deflection measuring device on the reflector. The reflector is added to a conventional auto-collimation angle measuring system, so that the problem that measurement is impossible because reflected light of a measured object deviates from the measuring system is solved and the auto-collimation working range is increased on the condition of the same working distance or the working distance is increased on the condition of the same working range. Owing to the specific design of the collimating mirror, the feedback imaging system and the reflector, the device is small, portable, and high in measurement precision, can monitor the stability of measurement environments, and can perform measurement rapidly.
