摘要： A method of and fixture for molding a product with an embedded ring. A system for molding a ring into a product including a rotational molding mold with an opening formed in the rotational molding mold sized to fit a ring. A fixture is removably couplable to the ring, wherein the ring and the fixture when coupled are removably couplable in the opening. The fixture is removed from the ring after the ring is molded into a product. A method of manufacturing a product with an embedded ring includes: coupling a ring to a fixture; clamping the fixture and the ring in an opening in a mold top; clamping the mold top to a mold bottom; rotomolding a product; unclamping the fixture from the mold top; uncoupling the fixture from the ring; unclamping the mold top and the mold bottom; and removing the product from the mold.

摘要： Described is a method for determining a dwell volume of a liquid chromatography system and a liquid chromatography system that can determined the system dwell volume. The method includes mixing a flow of a first solvent with a flow of a second solvent to form a solvent mixture. The flows of the first and second solvents are decreased and increased, respectively, to generate a gradient composition. A system pressure of the liquid chromatography system is measured to determine a pressure trace defined as the measured system pressure as a function of time. The dwell volume of the system is determined from a time delay determined between the gradient composition at the mixing location and the pressure trace. The method can be performed with a liquid chromatography system having a chromatographic column or a flow restrictor used in place of the chromatographic column.

摘要： A group study system is described. The group study system allows for students to form study groups with other students in the same class or related classes by utilizing various technologies that make such a system possible. The system provides for an anonymous creation of the study sessions and maintains the anonymity until all students joining the study session participate in the study session. These sessions can be in person and virtual. Hybrid and virtual sessions are becoming more and more important with the increasing presence of online education. This system harnesses technology in an innovative way to do something that was not possible years ago by enabling students to gather in a learning environment with other students who previously did not know each other. Additionally, the system operates to allow crowd sourcing of data for the input of exam data, including date and time of the exam in order to automatically extend exam reminders.

摘要： A system and method are provided for inferring location attributes from data entries. The method comprises for data entries in a structured data set format, a computer system selecting a sample of rows. The computer system then identifies columns containing geospatial and temporal information based on the column headings. The computer system next identifies location information within the structured data set. The computer system determines implied location information based on the identified location information. The computer system derives location values based on the identified and implied location information using consolidation rules, resulting in a final set of location attributes for the data entries. The computer system then associates the final set of location attributes with the data entries.

摘要： A method to control the operational status of a wind turbine is provided. An operator communication interface establishes a wireless point-to-point communication to a wind turbine communication interface. The wind turbine communication interface is an integrated part of the wind turbine. A control signal is transmitted from the operator communication interface via the point-to-point communication to the turbine communication interface. The control signal is transferred from the turbine communication interface to an internal control system of the wind turbine. The internal control system of the wind turbine changes the operational status of the wind turbine based on the control signal.
