The Hill equation can be applied in modeling big fish casino jackpot city rate at which a gene product is roger schmidt gehalt when its parent gene is being regulated by transcription factors e. However, as the substrate concentration is increased to higher and higher levels, the reaction rate no longer increases in proportion to the increase in substrate concentration.

According to the invention a driving situation in which macaire kartoffel withdrawal is requested from the hill-hold function, recognized, and eventually performed transmission efficiency changes are driven back to a normal level over a transition function, and then taking place, the exit from the hill-hold function and a smooth restarting is possible without rolling back.

When examined at different substrate concentrations, the rate of many enzyme-catalyzed reactions, or the rate of many carrier-mediated transport processes across biological membranes, exhibit a sigmoidal shape.

For hyperbolic reactions, when the substrate concentration is low, the reaction rate increases almost in a linear fashion with increasing substrate concentration. It is important to emphasize that the kinetics of transport for many transport proteins exhibit features that are very castle clash evolution deutsch to those of enzymes.

Global sensitivity measure such as Hill coefficient do not characterise the local behaviours of the s-shaped curves.

Instead, these features are well captured by the response coefficient measure [10] defined as:. From Wikipedia, the free encyclopedia.

This article is about the Hill equation as an equation used in biochemical characterization. For other uses, see Hill differential equation.

Sensitivity of activation functions to model assumptions". Journal of Theoretical Biology. Journal of Molecular Biology. From the prior art is known, in vehicles having an automatic transmission to implement a Hill-hold function.

Here, an idler roller of the vehicle is within the hill hold function to prevent the opposite direction desired by the driver.

In addition, by the hill hold function, the clutch load, especially in the state on the mountain and journeys can be greatly reduced.

Usually, the hill hold function is realized by a distortion of the transmission by means of the activation of additional clutches or brakes by means of activating various of the transmission.

It is also known to use free wheels, which are arranged at a suitable point in the transmission. In this case, a control of the transmission capacity of the starting clutch and the control of the transmission capability of the switching elements are so interact with one another, that at least one applique value of the braking torque applied to the output via the clutch or through the switching elements at least during an applicable time period in which the braking torque as a function of the vehicle incline is generated.

Des weiteren ist aus der Patentanmeldung Furthermore, from the patent application DE 28 Ferner ist im Rahmen der Patentanmeldung Further, in the context of the patent application DE 47 In this way, the time at which a result of releasing the previously actuated vehicle brake or as a result of releasing the drivetrain blocking of the hill hold function idle rollers of the motor vehicle is possible or imminent or begins may, by an evaluation of the various output signals of the multi-stage brake light switch can be determined.

In the known prior art processes the re-starting of the vehicle results after the deactivation of the hill hold function adversely in principle-related loss of comfort, since a smooth transition from the dissolving braking torque for increasing starting torque is very difficult to realize.

This object is solved by the features of claim 1. Other aspects and advantages of the invention will emerge from the dependent claims.

Accordingly, it is proposed that after recognition of a driving situation in which a hill-hold function is desired, a transition in the hill hold function is initiated by a transfer function, wherein the hill-hold function via a closed control loop is realized, the manipulated variable of the transmission output torque or the transmission input torque and the controlled variable of the vehicle position or a standstill of the vehicle such that the vehicle is adjusted to a zero position or a vehicle standstill.

Here nowadays used high-resolution speed sensors can already be used with rotation direction detection to ensure that adjust it to a zero position or a vehicle is stationary.

In an advantageous development of the invention it is proposed to make it difficult to rolling of the vehicle in addition with the aid of a specifically controlled deterioration in efficiency of the transmission.

According to the invention, the holding of the vehicle on a slope a closed control loop is, the manipulated variable of the control loop, the transmission output torque or the transmission input torque and the controlled variable is the vehicle position or a vehicle standstill.

According to the invention is brought about by the variation of the Getriebean- or -abtriebsmomentes the vehicle to a standstill and held there.

If the friction losses neglected, can be, for example, by the following equation, the slope determine where the vehicle can be held with the relevant engine speed at standstill: Hierbei wurden folgende Daten zugrundegelegt: Positive cooperativity refers to a scenario when the binding of one substrate facilitates the binding of another substrate to the protein.

In this case, there is no substrate binding cooperativity, and is indicative of either a single substrate binding site in the protein, or multiple binding sites that do not interact cooperatively.

For this reason, the Hill coefficient is generally not a good indicator of the number of binding sites. The Hill coefficient is a good indicator of the number of binding sites only when there is a very high degree of cooperativity among the sites.

It is important to emphasize that the kinetics of transport for many transport proteins exhibit features that are very similar to those of enzymes.

Similar to enzymes, transporters show specificity with respect to the substrate transported and, in addition, the rate of substrate transport across a biological membrane exhibits saturation at high substrate concentrations.

Therefore, the kinetics of many transport processes can be studied by using the Hill equation or the Michaelis-Menten equation.

The Michaelis-Menten equation can adequately describe the dependence of transport rate on the substrate concentration for facilitative transporters, secondary active transporters cotransporters and exchangers , and primary active transporters i.

The interactive graph provided below allows for a good understanding of the Hill equation, how the reaction velocity changes as a function of the substrate concentration, and how changes in V max , K 0.

Enter appropriate numerical values for the Maximum velocity V max , half-maximal concentration K 0. Then use the Add Plot button to generate a plot of reaction velocity versus the substrate concentration based on the Hill equation presented above.

An appropriate substrate concentration range will be used automatically. An unlimited number of plots may be added, but only the first twenty plots are assigned unique colors.

Optionally, the units may also be entered in the cells available. Any unit label entered will be added to the title for the corresponding axis.

Depending on user preference, the position of V max on the y-axis i. After generating a plot, use the top, left gray arrowheads to adjust the y-axis i.

When the Auto Scale feature is checked, the y-axis maximum is set to be equal to the highest V max plotted, and the x-axis maximum is set to be equal to five times the highest K 0.

The auto scale feature is applied automatically for the very first plot generated. Your browser does not support the HTML5 canvas tag.
