摘要:
A measuring transducer comprises a measuring tube vibrating at least at times during operation, having a wall thickness (s) and at least one oscillation sensor, especially an electrodynamic oscillation sensor, for producing at least one primary signal of the measuring transducer representing vibrations of the measuring tube. In the measuring transducer at least one securement element, especially a metal securement element, fixedly encircling the measuring tube essentially along a circumferential line thereof and having a total width (B), for holding a component of the oscillation sensor, especially a magnet coil or a permanent magnet, on the measuring tube is provided. The securement element has an essentially rectangular outer perimeter with a projection protruding out therefrom by a height (h) and serving for holding the component of the oscillation sensor. The projection has a width (e), which is smaller than the total width (B) of the securement element.

A method for testing a computer application includes identifying components of a version of the application, said components including one or more components that are one of new and modified, generating a keyword matrix of the identified application components. A search is performed in a test script repository with respect to components listed as at least one of the first and second dimensions of the matrix. The keyword matrix is populated with test case identification numbers in the search result. Based on the populated keyword matrix, one or more of (a) gaps in test case coverage for the version of the application, and (b) one or more test cases covering the version of the application are identified.

Thermal, flow measuring device and method for operating a thermal, flow measuring device. The thermal, flow measuring device has a first sensor with a first heatable resistance thermometer and at least an additional, second sensor with a second heatable resistance thermometer; wherein a decision coefficient is calculated according to the formula DC=(PC1−PC2)/PC1, with PC1(t=t1)=P1,1(t1)/(T1,heated;actual(t=t1)−Tmedium;actual(t=t1)) and PC2(t=t2)=P2,2(t2)/(T2,heated;actual(t=t2)−Tmedium;actual(t=t2)), with P being the heating powers consumed by the corresponding resistance thermometers at the points in time t, and T being the temperature values; wherein the value of the decision coefficient indicates the flow direction of a measured medium in the measuring tube.
摘要:
The present invention relates to hydroxyalkyl starch conjugates and a method for preparing the same, the hydroxyalkyl starch conjugate comprising a hydroxyalkyl starch derivative and a cytotoxic agent, the cytotoxic agent comprising at least one primary hydroxyl group, wherein the hydroxyalkyl starch is linked via said primary hydroxyl group to the cytotoxic agent. The conjugates according to the present invention have a structure according to the following formula HAS′(-L-M)n wherein M is a residue of the cytotoxic agent, L is a linking moiety, HAS′ is the residue of the hydroxyalkyl starch derivative, and n is greater than or equal to 1, and wherein the hydroxyalkyl starch derivative has a mean molecular weight (MW) above the renal threshold and a molar substitution (MS) in the range of from 0.6 to 1.5.

Systems and methods are provided that build and publish online documents. Source files of the online documents are automatically built into a book and published on a web site for review. A report regarding the build is provided to the author of the documents. The author can use the report to determine whether the build was successful, and whether manual intervention is necessary. The books are also archived.
摘要:
A bit error concealment (BEC) system and method is described herein that detects and conceals the presence of click-like artifacts in an audio signal caused by bit errors introduced during transmission of the audio signal within an audio communications system. A particular embodiment of the present invention utilizes a low-complexity design that introduces no added delay and that is particularly well-suited for applications such as Bluetooth® wireless audio devices which have low cost and low power dissipation requirements.
摘要:
A measuring tube, a measuring system and a method for determining and/or monitoring flow through a measuring tube, comprising a measuring tube, on which ultrasonic transducers are releasably placeable. The ultrasonic transducers transmit and/or receive ultrasonic signals, which pass through the measuring tube approximately coaxially to the measuring tube axis.
