Enabling Operator Reordering in Data Flow Programs Through Static Code Analysis

In many massively parallel data management platforms, programs are represented as small imperative pieces of code connected in a data flow. This popular abstraction makes it hard to apply algebraic reordering techniques employed by relational DBMSs and other systems that use an algebraic programming abstraction. We present a code analysis technique based on reverse data and control flow analysis that discovers a set of properties from user code, which can be used to emulate algebraic optimizations in this setting.Comment: 4 pages, accepted and presented at the First International Workshop on Cross-model Language Design and Implementation (XLDI), affiliated with ICFP 2012, Copenhage

Application of syndrome based Turbo decoding with adaptive computational complexity in LTE downlink

This paper describes the application of an adaptive complexity decoder for the Long Term Evolution (LTE) downlink Turbo code. The proposed decoding approach is based on the block syndrome decoding principle and enables adaptive reduction of decoding effort depending on current SNR and iteration number with negligible influence on decoding performance. Numerical results in context of LTE downlink using typical mobile channels are used to demonstrate the efficiency of the approach

The use of themes derived from plays by Tennessee Williams as a basis for an original dance production

The purpose of this study was to study the plays of Tennessee Williams in order to identify the basic recurring themes throughout the plays, and then to explore each of these themes in relation to their choreographic possibilities. The findings of the investigator are evidenced in the present written form and were projected into an extended dance production choreographed, designed, and staged in concert. The study was based exclusively on Tennessee Williams’ full-length plays. The investigator read all of the full-length plays of the well-known playwright, Tennessee Williams, and reviewed others of his works such as short stories, one-act plays, and poems. From the themes found in Williams’ plays, five recurring themes were identified and used as basis for choreography. The findings were organized into the prescribed thesis form and included the following relevant information concerning the presentation of the dance: (1) selection of the themes (2) selection of the personnel (3) selection of music (4) development of choreography (5) selection of costume (6) staging and lighting of the dance work. Summary and Evaluation: The study was concerned with the use of themes recurrent in Tennessee Williams’ plays as basis for choreography. The written substantiation presented was limited to the following areas: (1_ extended plays of Tennessee Williams (2) the appropriateness for choreography of recurring themes of Tennessee Williams (3) mixing of various art mediums. The investigation resulted in an extended dance production choreographed by the investigator. The description of the dance was limited to: (1) selection of themes (2) selection of personnel (3) selection of music (4) development of choreography (5) selection of costume (6) staging and lighting of the dance work
