摘要:
Leaf-level, multi-dimensional calculations are optimized by translating the multi-dimensional calculations to efficient query scripts. To generate efficient query scripts, rows are transposed to columns while affected rows are reduced by reversing calculation relationships. Actual calculations are performed on calculated columns. Transposing row-to-column enables fast arithmetic calculations. Reversing the calculation relationships enables a reduction of the rows that need to be processed.

It is very difficult to produce a negative wall angle from either negative or positive-tone chemically amplified resists, especially by e-beam lithography. This problem has now been overcome by first forming a photoresist pedestal in the conventional way, followed by flood exposing with electrons. Then, a second development treatment is given. This results in removal of additional material from the sidewalls, said removal being greatest at the substrate and least at the pedestal's top surface, resulting in negatively sloping sidewalls. Application of this method to a process for forming a pole tip for a vertical magnetic writer is also discussed.

For a user of a multi-dimensional database (e.g., as part of an OLAP system), a copy of at least a portion of the multi-dimensional database (i.e., a local cube) may be cached locally on the user's user device. The user then may query the local cube rather than the multi-dimensional database server. Further, the local cube may include not only data from the database but the functions representing the dependencies between pieces of the data. A reporting tool on the user's device may be configured to communicate with the local cube, such that the user may use the reporting tool to experiment with “what if” scenarios in local (e.g., volatile) memory by accessing the data and the functions from the local cube. For example, a thin client side query layer may be provided that directs all queries from a front-end reporting tool to the local cached data.

摘要:
Sharable extended cell information is used by multidimensional data models to enable cell annotations and line item details. Annotations are notes stored with a cell in a multidimensional dataset. Line item details permit levels of numeric detail below the lowest dimensional granularity. When receiving a multidimensional dataset in response to a query, a client application receives indicator information at the cell level, indicating to the client application that extended cell information is retrievable.

Embodiments are provided to use metadata to provide readable and/or writeable regions of a multi-dimensional space. In an embodiment, metadata can be used to define readable and/or writeable regions of a multi-dimensional data store. The various embodiments also use relational and/or multi-dimensional representations to resolve and validate readable and/or writeable regions of a multi-dimensional space. Metadata can also be used to in conjunction with writeback operations.

Organic compounds containing heteroatoms and their use in preparing Ziegler-Natta (Ziegler-Natta) catalyst with single activation center. The Ziegler-Natta olefin polymerization catalyst is preparing by adding organic or inorganic solid carrier or compound of them which is pre-activated by heating or pre-treated chemically, organic compound containing heteroatoms and metallic compound into magnesium compound/tetrahydrofuran solution. The Ziegler-Natta olefin polymerization catalyst prepared in the present invention is fluidizable powder and can prepare ethene homopolymer and copolymer of controllable construction with high catalytic activity, during homo-polymerization and combined polymerization with alpha-olefin of C3˜C18 under action of catalyst promoter such as alkyl aluminum, alkyl aluminoxane, and so on.
摘要:
A neck-support pillow comprising a resilient pillow body having a column-shaped medial portion and two cantilever arms, each arm attached proximate to an end of the medial portion, is described herein. In various embodiments, the arms may encircle a vertical axis, the vertical axis being perpendicular to a plane comprising a line formed between attachment locations of the two arms to the medial portion. Also, the arms and medial portion may form a well that is a size of a user's neck. Further, an arm height may be equal to a distance between the user's shoulder and jaw, the arm height being measured in a direction parallel to the vertical axis. Additionally, a medial portion height may be equal to a distance between an upper portion of the user's ear and the user's shoulder, the medial portion height being measured in a direction parallel to the vertical axis.
