  2. 1. Making Sense of Negative Numbers

    Author : Cecilia Kilhamn; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; metaphor; signed number; negative number; number sense; case study; longitudinal; social constructivism;

    Abstract : Numbers are abstract objects that we conceptualize and make sense of through metaphors. When negative numbers appear in school mathematics, some properties of number sense related to natural numbers become contradictory. The metaphors seem to break down, making a transition from intuitive to formal mathematics necessary. READ MORE

  4. 2. Object marking in the signed modality : Verbal and nominal strategies in Swedish Sign Language and other sign languages

    Author : Carl Börstell; Maria Koptjevskaja Tamm; Irit Meir; Roland Pfau; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; sign language; object marking; differential object marking; argument structure; transitivity; valency; directionality; handshape; pronoun; perspective; Swedish Sign Language; Al-Sayyid Bedouin Sign Language; Israeli Sign Language; Linguistics; lingvistik;

    Abstract : In this dissertation, I investigate various aspects of object marking and how these manifest themselves in the signed modality. The main focus is on Swedish Sign Language (SSL), the national sign language of Sweden, which is the topic of investigation in all five studies. READ MORE

  5. 3. Contributions to low-complexity digital filters

    Author : Oscar Gustafsson; Keshab K. Parhi; Linköpings universitet; []
    Keywords : ;

    Abstract : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in many digital signal processing (DSP) systems. Typical applications include interpolation, decimation, and noise suppression.The work presented in the thesis can be divided into four parts. READ MORE

  6. 4. Low Power and Low complexity Constant Multiplication using Serial Arithmetic

    Author : Kenny Johansson; Lars Wanhammar; Oscar Gustafsson; Süleyman Demirsoy; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filters; Computer arithmetic; Multiplication; Addition; Low power; Switching activity; Electronics; Elektronik;

    Abstract : The main issue in this thesis is to minimize the energy consumption per operation for the arithmetic parts of DSP circuits, such as digital filters. More specific, the focus is on single- and multiple-constant multiplication using serial arithmetic. The possibility to reduce the complexity and energy consumption is investigated. READ MORE

  7. 5. Efficient and Flexible Embedded Systems and Datapath Components

    Author : Magnus Själander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flexible; Twin-Precision; Scheduling; Embedded; Multiplier; Multi-Core;

    Abstract : The comfort of our daily lives has come to rely on a vast number of embedded systems, such as mobile phones, anti-spin systems for cars, and high-definition video. To improve the end-user experience at often stringent require-ments, in terms of high performance, low power dissipation, and low cost, makes these systems complex and nontrivial to design. READ MORE
