2. 1. Families of cycles and the Chow scheme

   Author : David Rydh; Dan Laksov; Martin Olsson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Families of cycles; Chow scheme; Hilbert scheme; zero-cycles; divided powers; symmetric tensors; symmetric product; Weil restriction; norm functor; Algebra and geometry; Algebra och geometri;

   Abstract : The objects studied in this thesis are families of cycles on schemes. A space — the Chow variety — parameterizing effective equidimensional cycles was constructed by Chow and van der Waerden in the first half of the twentieth century. Even though cycles are simple objects, the Chow variety is a rather intractable object. READ MORE

4. 2. A Cross-layered Pilot Scheme for IEEE 802.11p

   Author : Keerthi Nagalapur; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular communications; FPGA implementation; Channel Estimation; Cross-layer; Pilot Scheme; IEEE 802.11p; OFDM;

   Abstract : Vehicular communication is expected to be a part of the future transportation system and promises to support a plethora of applications for traffic safety, traffic efficiency, and fuel efficiency. Traffic safety applications, such as collision avoidance, demand reliable communications with low latency. READ MORE

5. 3. MaMiS : A Programming Environment for Numeric/Symbolic Data Processing

   Author : Peter A. J. Nagy; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheme; MATLAB; MACSYMA; Numeric symbolic data processing;

   Abstract : This thesis describes a programming environment (called MaMiS - MATLAB and MACSYMA in Scheme) for symbolic/numeric data processing. This programming environment is based on three main parts:Scheme, a symbol manipulating language (a LISP dialect)MATLAB, a program for numeric scientific calculationsMACSYMA, a program for formula manipulationsA fourth part is added to MaMiS, the text editor DNU Emacs, which is used as an interface between the user and Scheme.

6. 4. On finite element schemes for Vlasov-Maxwell system and Schrödinger equation

   Author : Christoffer Standar; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Schrödinger equation; Nitsche scheme; Streamline diffusion; Vlasov-Maxwell; a posteriori error analysis; a priori error analysis; hp-scheme; a posteriori error analysis;

   Abstract : This thesis treats finite element schemes for two kind of problems, the Valsov-Maxwellsystem and the nonlinear Schrödinger equation. We study streamline diffusion schemes applied for numerical solution of the one and one-half dimensional relativistic Vlasov-Maxwell system. The study is made both in a priori and a posteriori settings. READ MORE

7. 5. Designing for the incorporation of programming in mathematical education : Programming as an instrument for mathematical problem solving

   Author : Andreas Borg; Kenneth Ruthven; Maria Fahlgren; Chantal Buteau; Karlstads universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics; math; upper secondary; problem solving; programming; coding; instrument; instrumental genesis; education; mathematics education; scheme; matematik; skola; utbildning; problemlösning; programmering; kodning; instrument; instrumental genes; utbildning; matematikdidaktik; schema; Pedagogiskt arbete; Educational Work; Matematikdidaktik; Mathematics didactics;

   Abstract : This study explored Swedish upper secondary school students’ use of programming for mathematical purposes. The aim of the study was to investigate the process through which students learn how to use a programming environment as a technical artefact during mathematical problem solving and how the orchestration of such learning situations could facilitate this process.
