Abstract: The present invention relates to the field of fluid heat transfer, and discloses a heat transfer enhancement pipe as well as a cracking furnace and an atmospheric and vacuum heating furnace including the same. The heat transfer enhancement pipe (1) includes a pipe body (10) of tubular shape having an inlet (100) for entering of a fluid and an outlet (101) for said fluid to flow out; internal wall of the pipe body (10) is provided with a fin (11) protruding towards interior of the pipe body (10), the fin (11) spirally extends in an axial direction of the pipe body (10), wherein a height of the fin (11) gradually increases from one end in at least a part extension of the fin. The heat transfer enhancement pipe can reduce thermal stress of itself, thereby increasing service life of the heat transfer enhancement pipe.

Abstract: Disclosed are a method and electronic device for determining a faulty state of a storage device. A first time length of a first access to a set of blocks of a storage device is determined. Then, the first time length of the access and a threshold time length are compared. If the first time length exceeds the threshold time length, it is determined that the blocks are in a potential faulty state.

Abstract: A method and device for measuring a substance's concentration in a fluid. The method includes first passing a sample to be measured through a chemical sensor at least twice and recording the response value each time; forming a simultaneous equation set using the equation relation between the response value obtained during each measurement and the concentration of the substance, and the mass equation relation satisfied by the concentration change caused by a physical, chemical reaction during each measurement and by the change of the mass, electric quantity, and heat; solving for the concentration of the substance measured and the sensor calibration parameter. The method, used as an absolute measurement method, can be applied to calibrate the sample concentration of a fluid, overcomes the effects on the measurements caused by temperature, humidity, pressure, and some interfering gas, requires no sensor calibration, and substantially enhances the measurements' stability and reliability.

Abstract: A self-calibrating gas sensor comprises a steady current measuring gas line composed of valves, pumps and a current-type electrochemical sensor, and a coulomb analyzing gas line composed of said valves, said pumps, said current-type electrochemical sensor and a sample chamber. The two gas lines can be interchanged between measurement and analysis by controlling valves. The sensor can measure gas concentrations, and self-calibrate its sensitivity without the need of standard gases for external calibration.

Abstract: A method and system of constraint-based project scheduling. The method comprises maintaining a first database containing project scheduling data associated with at least a current period and a next period of an assignment plan; maintaining a second database containing data associated with a look ahead plan, the look ahead plan covering at least an overlap portion of the next period of the assignment plan such that the look ahead plan overlaps the assignment plan; transferring data associated with one or more shielded tasks having a starting time within the overlap portion of the next period from the second database into the first database as a modification of the project scheduling data associated with the next period of the assignment plan; and executing the project according to the next period of the assignment plan based on the modified project scheduling data associated with the next period in the first database.
