Abstract:
Described is a technology by which an expression in a database engine is executed against stacks of data. Each instruction of the expression is evaluated against the data stacks until completed against each data stack, such as by iterating to execute an instruction through the data stacks before executing the next instruction. The data may be arranged in the data stacks (in memory) in various ways, such as to have each data stack contain the data of one database row, (e.g., with the data stack elements comprising column data. Data may be grouped, such as to put the data from different rows into the same data stack.

The subject disclosure is directed towards technology by which an expression in a database engine is executed against stacks of data. Each instruction of the expression is evaluated against the data stacks until completed against each data stack, such as by iterating to execute an instruction through the data stacks before executing the next instruction. The data may be arranged in the data stacks (in memory) in various ways, such as to have each data stack contain the data of one database row, (e.g., with the data stack elements comprising column data.

Abstract:
The invention relates to an intercooler for a motor vehicle with an internal combustion engine that is supercharged in steps. In this case, the intercooler has an air outlet opening as well as two air inlet openings, a heat exchanger module being associated with each air inlet opening. Air channels of the two heat exchanger modules are ultimately brought together in an air box of the intercooler, which is connected to the air outlet opening. It is thus made possible to bring together compressed charging air from two supercharging assemblies only in the area of the intercooler. To improve the pressure ratios during operation of only one supercharging assembly, a non-return valve is provided in an air channel. Thus, a module for separately bringing the airways together can be eliminated, thereby reducing the installation space requirement.
Abstract:
The invention relates to vaporization source, an evaporation chamber, a coating method and a nozzle plate. The vaporization source according to the invention makes it possible to generate a high, stable melt flow rate having improved layer thickness homogeneity under vacuum conditions in a selenium atmosphere. The direction of the molecular flow of the vaporization source can be adjusted with respect to the substrate support located above the vaporization source.
