2. 1. Let's Eat Together: Methods and Tools for Inclusive City Design Practice

   Author : Chotima Ag-ukrikul; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Experience-based; Inclusive city design; Commensality; Liveable City; Eatscape; Urban Vernacular; Design Ritual;

   Abstract : This thesis studies how the practice of eating together impacts on liveable city making. In this thesis, the practice of eating together is called commensality, which is a collective action that creates shared environments. Through time these environments are turned into recognized meeting places where locals gather. READ MORE

4. 2. Software tools for matrix canonical computations and web-based software library environments

   Author : Pedher Johansson; Bo Kågström; Erik. Elmroth; Alan Edelman; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Canonical structure; Jordan canonical form; controllability; StratiGraph; Matlab toolbox; Kronecker canonical form; matrix; matrix pencil; perturbation theory; closure hirerarchy; matrix stratification; control system; observability; Numerical analysis; Numerisk analys;

   Abstract : This dissertation addresses the development and use of novel software tools and environments for the computation and visualization of canonical information as well as stratification hierarchies for matrices and matrix pencils. The simplest standard shape to which a matrix pencil with a given set of eigenvalues can be reduced is called the Kronecker canonical form (KCF). READ MORE

   Abstract : In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities.

6. 4. Tools for Control System Design : Stratification of Matrix Pairs and Periodic Riccati Differential Equation Solvers

   Author : Stefan Johansson; Bo Kågström; Erik Elmroth; Paul Van Dooren; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; control system design; stratification; controllability; observability; matrix pair; canonical forms; linear quadratic regulator; periodic systems; periodic Riccati differential equation; Computer science; Datavetenskap; Numerical Analysis; numerisk analys;

   Abstract : Modern control theory is today an interdisciplinary area of research. Just as much as this can be problematic, it also provides a rich research environment where practice and theory meet. This Thesis is conducted in the borderline between computing science (numerical analysis) and applied control theory. READ MORE

7. 5. Design and optimization of parallel haptic devices : Design methodology and experimental evaluation

   Author : Suleman Khan; Kjell Andersson; Jan Wikander; Ölvander Johan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical simulation; 6-DOF haptic devices; design methodology.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : The simulation of surgical procedures, in the case of hard tissues such as bone or teeth milling, using a haptic milling surgery simulator requires a haptic device which can provide high stiffness and transparency. To mimic a real milling process of hard tissue, such as for example creating a narrow channel or cavity, the simulator needs to provide force/torque feedback in 5–6 degrees of freedom (DOF). READ MORE
