Abstract: A system stores visual content, and displays the visual content on a display unit in an undistorted, overview projection. The system receives input from a user to focus on a topic in the undistorted, overview projection, and transforms the undistorted, overview projection into a focused display showing the topic selected by the user and content related to the topic selected by the user in a continuous sequence of increasingly distorted projections. In the focused display, the content that is not related to the topic selected by the user does not move on the focused display, and the content that is related to the topic selected by the user moves towards the topic selected by the user on the focused display.

The visualization engine may include a request handler configured to receive a magnification request to magnify the object at a magnification speed, a threshold manager configured to determine a data threshold at which fetching of the object data must be initiated to ensure receipt thereof prior to the visual threshold being reached, and an object comparator configured to initiate fetching of the object data, based on the visual threshold, the data threshold, and the magnification speed. The visualization engine may then display the object data within the object upon magnification of the object meeting the visual threshold.

Abstract: The invention relates to a process for preparing an ester mixture, in which an n-butene-containing feed mixture having a composition which changes over time is first oligomerized and then converted by hydroformylation, hydrogenation and esterification to an ester mixture. In this process, an approximation of the actual viscosity of the ester mixture is determined. The problem that it addresses is that of specifying a comparatively simple process which enables conversion of an n-butene with a variable composition over time to an ester mixture having a viscosity which can be kept very substantially constant over a long period even when an inconstant C4 source which delivers fluctuating qualities over this period is utilized. This is achieved through controlled use of a second raw material, namely ethene. It has been found that the viscosity of n-butene-based ester mixtures can be influenced by controlled use of ethene in the preparation of the ester precursors.

Abstract: Techniques are described for providing visual bundlers that group and represent specified data subsets of very large datasets in a manner that is expressive and intuitive for a user, and which provide a dynamic, configurable visualization that may be leveraged by the user to search, aggregate, or otherwise interact with the data of a very large dataset. By nesting such visual bundlers, a geometric equivalent of a dynamically-generated search tree is realized, in which a structure for executing a search for a desired data element is not required to be fixed or otherwise predefined. Consequently, during a runtime of providing related visualizations, multiple alternative search trees may be created for the same underlying content, with minimal effort, and in a manner that is highly intuitive and useful for the user.

Abstract: The invention relates to a process for preparing 1,3-butadiene by heterogeneously catalysed oxidative dehydrogenation of n-butene, in which a butene mixture comprising at least 2-butene is provided. The problem that it addresses is that of specifying a process for economically viable preparation of 1,3-butadiene on the industrial scale, which is provided with a butene mixture as raw material, wherein the 1-butene content is comparatively low compared to the 2-butene content thereof, and in which the ratio of 1-butene to 2-butene is subject to variation. This problem is solved by a two-stage process in which, in a first stage, the butene mixture provided is subjected to a heterogeneously catalysed isomerization to obtain an at least partly isomerized butene mixture, and in which the at least partly isomerized butene mixture obtained in the first stage is then subjected, in a second stage, to oxidative dehydrogenation. The two-stage process leads to higher butadiene yields compared to the one-stage process.
