A roll stability control system (18) for an automotive vehicle (10) includes an active anti-roll bar system (62) and a rollover sensor (40) that generates a roll attitude signal indicative of a pending rollover of the vehicle. A controller (26) controls the active anti-roll bar system (62) to prevent the vehicle from rolling over in response to the roll attitude signal. The controller (26) may also control a brake system (60). The brake system may be used in addition to the active anti-roll bar system to prevent rollover of the vehicle.

The invention discloses an evaluation method for the low temperature crack resistance of asphalt. The method includes the steps of: taking or preparing a pedestal and a non-expansive circular ring, wherein the middle of the pedestal is provided with an annular groove, the non-expansive circular ring is closely sleeved on the inner ring wall of the annular groove, the pedestal is equipped with a synapse on the outer ring wall of the annular groove, and the synapse is a cylindrical synapse horizontally disposed on the outer ring wall of the annular groove; heating asphalt, pouring the asphalt into an annular space between the non-expansive circular ring and the outer ring wall of the annular groove, and performing cooling molding to obtain an asphalt circular ring; conducting cooling till the asphalt circular ring fractures, detecting and recording the temperature value and the instantaneous strain value of the non-expansive circular ring at a position corresponding to the synapse. The method performs approximate simulation of a corresponding maximum fracture strain during pavement fracture, establishes correlation with the pavement mixture actual low temperature condition, can realize fixed-point fracture, and can measure the strength value of a fracture part specifically. By means of the method, the measured ring fracture temperature has good correlation with TSRST fracture temperature, and the method has good accuracy and repeatability.

The invention relates to a method for the registration of an ink-jet printing texture image based on a unit decomposition optical flow field. The method comprises the following steps of: 1, inputting a reference image and a distorted image and setting iteration implementation parameters; 2, performing incomplete Cholesky decomposition on a coefficient matrix of a registration displacement vector;3, taking a primary function as a linear primary function, and solving a unit decomposition coefficient column vector by a preconditioned conjugate gradient method according to an iteration error value; 4, calculating an overall error estimation value, and adjusting a scale space to obtain a rough scale space; 5, taking the primary function as a second order primary function, and solving the unitdecomposition coefficient column vector on the rough scale space according to a local error estimation result to obtain a fine scale space; and 6, stacking and expanding the unit decomposition coefficient column vector on the fine scale space to obtain the registration displacement vector and complete registration. By the method, the registration representation capability of a feature texture curve can be effectively improved, the registration precision in noise environment is improved, and the registration speed in noise environment is increased. Therefore, the method is applicable for the registration of the ink-jet printing texture image.

The invention discloses a household appliance, a remote control method thereof, a server, and a terminal control device. The remote control method comprises the following steps: obtaining voice information; performing voice recognition on the obtained voice information, and extracting preset feature information from a voice recognition result; generating a reservation instruction and a reservationtime of the household appliance according to the extracted feature information; and at the arrival of the reservation time, controlling the household appliance to operate according to the generated reservation instruction of the household appliance. By adoption of the remote control method disclosed by the invention, the technical problem that the control time is inaccurate when the household appliance is controlled to operate in advance in the prior art is solved, the user operation is not only convenient, and the effective control of the advanced operation of the household appliance is achieved as well.

The invention discloses a freeze-fracture disc structure for low-temperature ring cracking of asphalt, and a low-temperature ring-crack tester for asphalt. The freeze-fracture disc structure for low-temperature ring cracking of asphalt comprises a base and a no-expansion circle ring, wherein the center of the base is provided with an annular groove, the no-expansion circle ring tightly sleeves the inner ring wall of the annular groove, annular accommodating space for placing asphalt is formed between the outer wall of the no-expansion circle ring and the annular groove, and the outer ring wall of the annular groove is provided with a synapse. Asphalt is heated and poured into an annular area; ambient temperature is allowed to continuously decrease; an asphalt circular ring shrinks and the no-expansion circle ring slightly shrinks, so temperature stress is produced in an asphalt circular ring sample; due to arrangement of the synapse, a fracture point of an asphalt circular ring at low temperature is allowed to be located at the synapse; and the ring crack temperature and ring crack strength of the asphalt circular ring are eventually calculated by detecting the value of temperature variation and stress at the synapse. The disc structure is applied to the low-temperature ring-crack tester for asphalt, and the tester can approximately simulate corresponding maximal fracture stress during fracture of a pavement and correlates the fracture stress with the actual low temperature condition of a pavement mixture.

The invention discloses a method for supporting the side of a roadway with a constant resistance yielding pressure of a hard roof. Among them, the constant resistance pressure pad is an external injection monolithic hydraulic prop with a deformed structure of a short and sturdy live column; the constant resistance pressure pad is installed on the filling body, and the sum of its maximum lifting height and the height of the filling body is equal to The initial height of the roadway. In the early stage of the invention, the constant resistance characteristic of the constant resistance pressure pad is used to control the given deformation of the top plate; when the top plate sinks to the compression limit of the constant resistance pressure pad, it is withdrawn in time, and the filling body is used to control the limited deformation of the top plate . The invention has the characteristics of strong adaptability to deformation, good roadway forming, simple operation, low support cost, good roadway safety, etc., and is especially suitable for roadside support of roadway with hard roof during gob-side entry retention.
