1. 1. Improving network layer reaction times

   Författare :Pierre Fransson; Luleå tekniska universitet; []
   Nyckelord :;

   Sammanfattning : This thesis presents two proposals for improving network layer reaction times and an investigation into the consequences of using IPv4 options. The first proposal, the Selective TRuncating Internetworking Protocol (STRIP), is an augmentation of the IP networking layer. LÄS MER

3. 2. Stochastic Simulation of Multiscale Reaction-Diffusion Models via First Exit Times

   Författare :Lina Meinecke; Per Lötstedt; Stefan Engblom; Ramon Grima; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computational systems biology; diffusion; first exit times; unstructured meshes; reaction-diffusion master equation; macromolecular crowding; excluded volume effects; finite element method; backward analysis; stochastic simulation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Sammanfattning : Mathematical models are important tools in systems biology, since the regulatory networks in biological cells are too complicated to understand by biological experiments alone. Analytical solutions can be derived only for the simplest models and numerical simulations are necessary in most cases to evaluate the models and their properties and to compare them with measured data.

4. 3. The effects of valenced odors on facial perception

   Författare :Elmeri Syrjänen; Jonas Olofsson; Håkan Fischer; Thomas Hummel; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Valenced odors; Facial expressions; Disgust; Happiness; Olfaction; Emotion; Reaction Times; Evaluation; Ratings; EEG; ERP; N170; Psychology; psykologi;

   Sammanfattning : We use our senses to navigate in the world. An important property of olfaction, the sense of smell, is to enable us to approach beneficial things, and to avoid what might be toxic or otherwise harmful in our environment. Other peoples’ behaviors are also paramount for our survival. LÄS MER

5. 4. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring

   Författare :Peter Tobias; Ignaz Eisele; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide; high temperature; gas sensors; field effect devices; MISdevices; Schottky diodes; experimental design; reaction kinetics; mass transport; car exhaust; multipoint injection; response times; cylinder specific; on-board diagnosis;

   Sammanfattning : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.

7. 5. Fast pyrolysis of biomass : primary products and reaction pathways

   Författare :David Usino; Tobias Richards; Weihong Yang; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast pyrolysis; Py-GC-MS FID; Primary reactions; Cellulose; Xylan; Lignin; Birch wood; Co-pyrolysis; Mahogany; Iroko; Palm kernel shell; Biomass blend; Biomass interaction; Pretreatment; Resource Recovery; Resursåtervinning;

   Sammanfattning : Pyrolysis of biomass to produce liquid fuel and chemicals has been considered as an alternativeto fossil fuel because biomass has a lower environmental impact; moreover, it is renewable andcould be sustainable. However, the process of bio-oil production involves a series of complexchemical reactions which are dependent on the biomass feedstock and composition,temperature, heating rate as well as residence time.
