  2. 1. Memory and communication in typically developing infants and children with Autism Spectrum Disorder : Behavioral and electrophysiological indices

    Author : Emelie Nordqvist; Mikael Heimann; Mary Rudner; Magnus Lindgren; Leslie Carver; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Memory development; communication; deferred imitation; ERP; autism spectrum disorder; Minne; kommunikation; fördröjd imitation; ERP; autismspektrumstörning;

    Abstract : The purpose of this thesis is to investigate how variations in early memory capacity seems, both in children with typical development in children with autism. More specifically, variations in early memory is examined here over time, and its relationship to early (verbal and non-verbal) communication skills. READ MORE

  4. 2. Essays on Capability Indices for Autocorrelated Data

    Author : Erik Wallgren; Anders Christoffersson; Jan Wretman; Uppsala universitet; []
    Keywords : Statistics; Capability Indices; Autocorrelated data; Monte Carlo Simulations; Statistik;

    Abstract : The use of process capability indices in the industry is traditionally based on the assumptions that a sample from a process are observations on independently, identically and normally distributed random variables, IIN. However, all three assumptions are open to discussion and in this thesis, the estimation of the indices is studied when the assumption of independence is not fulfilled. READ MORE

  5. 3. Voltage Sags: Single event characterisation, system performance and source location

    Author : Roberto Chouhy Leborgne; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source location; characterisation; voltage sags dips ; Power quality; indices;

    Abstract : This thesis deals with one of the most important disturbances that affect the quality of the electrical supply. Voltage sags cause industrial processes malfunction, producing an enormous economical impact. A voltage sag is defined as a short duration reduction of the rms voltage. READ MORE

  6. 4. Contributions to multivariate process capability indices

    Author : Ingrid Tano; Anders Lundquist; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk statistik inriktning industriell statistik; Mathematical Statistics with special emphasis on Industrial Statistic; Matematisk statistik; Matemathical Statistics; Manufacturing and materials engineering;

    Abstract : The work presented in this thesis considers multivariate process capability indices (MPCIs) with focus on confidence intervals and tests for MPCIs. It also includes a case study, where multivariate statistical analysis and MPCIs are applied to data from a thermal spraying process at Volvo Aero Corporation. READ MORE

  7. 5. Contributions to process capability indices and plots

    Author : Malin Albing; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics with special emphasis on Industrial Statistic; Matematisk statistik inriktning industriell statistik;

    Abstract : This thesis presents contributions within the field of process capability analysis. Process capability analysis deals with how to assess the capability of processes. Based on process capability analysis one can determine how the process performs relative to its product requirements or specifications. READ MORE
