1. 1. Shells and filament in flows

   Författare :Vipin Agrawal; Dhrubaditya Mitra; Supriya Krishnamurthy; Gerhard Gompper; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chaos; Elastic filaments; Shells; Exosomes; Stokes flow; Theoretical Physics; teoretisk fysik;

   Sammanfattning : The motivation to study elastic structures such as filaments and shells stemmed from its application in the construction of tall buildings, bridges etc. Interest in this field has rekindled in the past decades due to growing interest in understanding biological materials and because of possible applications in nanoscience and medicine.

3. 2. Simple Models for Complex Nonequilibrium Problems in Nanoscale Friction and Network Dynamics

   Författare :David Andersson; Astrid de WIjn; Supriya Krishnamurthy; Nicola Manini; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tribology; nanofriction; 2d materials; graphene; image reconstruction; social dynamics; common-pool resource; collective action; simple models; teoretisk fysik; Theoretical Physics;

   Sammanfattning : This doctoral thesis investigates three different topics: How friction evolves in atomically thin layered materials (2D materials); How social dynamics can be used to model grand scale common-pool resource games; Benchmarking of various image reconstruction algorithms in atomic force microscopy experiments. While these topics are diverse, they share being complex out-of-equilibrium systems. LÄS MER

4. 3. On the Performance Analysis of Large Scale, Dynamic, Distributed and Parallel Systems

   Författare :John Ardelius; Seif Haridi; Supriya Krishnamurthy; Mark Jelasity; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Performance analysis distributed systems; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Evaluating the performance of large distributed applications is an important and non-trivial task. With the onset of Internet wide applications there is an increasing need to quantify reliability, dependability and performance of these systems, both as a guide in system design as well as a means to understand the fundamental properties of large-scale distributed systems.

5. 4. Finite-time  non-equilibrium thermodynamics of a colloidal particle

   Författare :Sreekanth K. Manikandan; Supriya Krishnamurthy; Jens H. Bardarson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

   Sammanfattning : In this thesis we have thermodynamically characterized finite time processes performed on a colloidal particle, kept in contact with thermal reservoir(s). Thermodynamic processes are implemented on the colloidal particle by systematically changing the confining potential in a time dependent way, according to an external driving protocol or by controlling the environmental conditions over a finite duration.

7. 5. Non-equilibrium thermodynamics at the microscopic scales

   Författare :Sreekanth K Manikandan; Supriya Krishnamurthy; David Lacoste; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Non-equilibrium statistical Physics; entropy production; teoretisk fysik; Theoretical Physics;

   Sammanfattning : An inherent feature of small systems in contact with thermal reservoirs, be it a pollen grain in water, or an active microbe flagellum, is fluctuations. Even with advanced microscopic techniques, distinguishing active, non-equilibrium processes defined by a constant dissipation of energy to the environment from passive, equilibrium processes is a very challenging task and a vastly developing field of research.
