Abstract: For identification of the quality of trustworthiness and reliability of software components, an eigenvector based approach is used in which a procedure invocation graph of a set of software components is provided. Subsequently, the authoritativeness of a first software component is calculated as a function of an eigenvector of the provided procedure invocation graph. For calculating the authoritativeness, a flexible algorithm, which considers background knowledge is used. Applying the method, software code can be analyzed more efficiently. The method can be applied in software code analysis and/or in software architecture analysis.

Abstract: The present invention relates to a semiconductive polymer composition comprising an olefin homo- or copolymer wherein the composition has a direct current volume resistivity of less than 1000 Ohm·cm at 90° C., an elongation at break which after aging for 240 hours at 135° C. does not change by more than 25%, and a total number of structures of 20 or less in the SIED test. Furthermore, the present invention relates to an electric power cable comprising a conductor, a semiconducting layer and, adjacent to the semiconducting layer, an insulation layer, wherein the semiconducting layer is formed by said semiconductive polymer composition and to the use of said semiconducting polymer composition for the production of a semiconductive layer of an electric power cable.

Abstract: A process is proposed for distillatively obtaining pure 1,3-butadiene from crude 1,3-butadiene in a plant comprising one or more distillation columns, comprising supply of a feed stream of crude 1,3-butadiene to the one distillation column or the first of the plurality of distillation columns, the one distillation column or the plurality of distillation columns having a flange with an internal diameter of ?80 mm, comprising two mutually opposite plane-parallel surfaces (1) with an intermediate seal (2) which seals the interior of the one distillation column or of the first of the plurality of distillation columns from an intermediate space (3) on the atmosphere side between the two mutually opposite plane-parallel surfaces (1), and the intermediate space (3) on the atmosphere side between the two mutually opposite plane-parallel surfaces (1) being closed off from the atmosphere to form a chamber, wherein the chamber is purged continuously during the operation of the plant with a low-oxygen gas or a low-oxygen

Abstract: Methods and systems for automatically controlling aircraft takeoff rolls are disclosed. A method in accordance with one embodiment of the invention includes receiving an indication of a target takeoff roll path for an aircraft, and automatically controlling a direction of an aircraft, while the aircraft is on a takeoff roll, to at least approximately follow the target takeoff roll path. The method can further include providing an input to a rudder of the aircraft and, upon receiving an indication of an engine failure, can transfer the input from the rudder to a rudder trim element. In still further embodiments, the method can include commanding a ground track angle when an airspeed of the aircraft reaches a threshold value, and maintaining the ground track angle as the airspeed of the aircraft exceeds the threshold value.

Abstract: This food storage container would have an extra half-circular piece of plastic (tabs) formed into the very outside rim of the lid and one formed on the very outside rim of the container. These tabs would have holes in them in which a plastic cord would slide through the tab on the lid and the tab on the container. The plastic cord would be formed so each end of the cord would be approximately twice the diameter of the holes in the tabs creating objects (i.e. stoppers) that would cause the lid and the container to be attached by means of the plastic cord. The plastic cord would be just long enough to allow the lid to be placed under the container.

Abstract: An aqueous coating composition is provided which includes crosslinkable film-forming resin and about 0.01 to about 25 weight percent on a basis of total resin solids of an amphiphilic adjuvant having an acid value of less than 30, a water-soluble polar end including at least one terminal hydroxyl group and a water-insoluble hydrocarbon end including at least seven contiguous carbon atoms. The coating composition is useful as a monocoat or primer, basecoat or clearcoat in a multi-component composite coating composition for automotive applications.

Abstract: A valve control unit, especially for internal combustion engines, having a valve fixed on a valve spindle which is mounted for angular rotation in a valve body supporting a control motor for positioning the valve spindle. The motor is coupled to the valve spindle through a gear mechanism and is disposed in the valve body with a sensor unit for sensing an adjusted angular position of the valve spindle. A cover is provided to be fastened on the valve body and the cover supports an electric clutch element, a bearing for an end of the motor shaft of the control motor and functional parts of the control motor such that assembly of the control motor is completed upon mounting the cover on the valve body.

Abstract: Methacrylic acid can be prepared with advantage by gas phase oxidation of methacrolein or isobutyraldehyde over Mo- and P-containing catalysts at from 250.degree. to 400.degree. C. with cooling of the hot reaction gas to below 100.degree. C., absorption of the methacrylic acid in a water-operated absorption column, at below 100.degree. C. and partial recycling into the oxidation reactor after admixture of methacrolein or isobutyraldehyde and oxygen by feeding a quantity of methacrolein or isobutyraldehyde equal to the quantity of methacrolein or isobutyraldehyde consumed in the reaction in liquid form together with a polymerization inhibitor into the reactor gas in the lower two-thirds of the absorber column and upstream of the feed point for the fresh methacrolein or isobutyraldehyde or down-stream of the absorption column splitting off the reactor off-gas a side stream which is washed in a wash column operated with water at <10.degree.
