1. 6. Simulating the palaeorecord of northern European lakes using a coupled lake-catchment model

   Författare :Jüri Vassiljev; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climatology; cartography; pedology; geomorphology; Physical geography; northern Europe; catchment geometry; Holocene; overflow lakes; climate change; Water- and energy-balance modelling; lake-level changes; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Sammanfattning : A coupled lake-catchment model was developed to examine the controls on lake-level changes in currently overflowing lakes during Holocene. The lake energy-balance is simulated as the one-dimensional vertical heat transfer by eddy diffusion and convective mixing. LÄS MER

3. 7. Techniques to Reduce Inefficiencies in Hardware Transactional Memory Systems

   Författare :Mridha Mohammad Waliullah; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intermediate checkpoint; conflicting address prediction; Bloom filter; conflict resolution; multiprocessor; speculative buffer overflow; parallel programming; 5C model for cache-misses; transactional memory; conflict classification; starvation;

   Sammanfattning : The recent trend of multicore CPUs pushes for major changes in software development. Traditional single-threaded applications can no longer get a sustainable performance boost from this new generation of CPUs that consist of multiple processors (cores). LÄS MER

4. 8. Cardiovascular and sympatho-adrenal responses to mental stress with special reference to the regulation of human forearm blood flow

   Författare :Madeleine Lindqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :adrenaline; axillary blockade; beta-receptor blockader; calcium channel blockers; cholinergic blockingagents; felodipine; hypertension-primary; noradrenaline; skeletal muscle; sodium nitroprusside; stress-psychologicai; vascular resistance;

   Sammanfattning : The cardiovascular and sympatho-adrenal responses to a standardized mental stress test (Stroop's colour word conflict test CWT) were studied in 63 healthy and 11 hypertensive men by intraarterial pressure measurements, forearm blood flow by occlusion plethysmography and noradrenaline (NA) and adrenaline (ADR) determinations in arterial and venous plasma. One study included central hemodynamics by right heart catheterization and NA turnover by an isotope dilution method, permitting studies of NA kinetics in the whole body and in a regional vascular bed (the forearm) in hypertensive patients and age-matched controls.

5. 9. Extremum-Seeking Control of Industrial-Scale Fermentation Processes

   Författare :Ola Johnsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The work presented here is based on two papers, both pertaining to perturbation-based control strategies in industrial fed-batch fermentation processes. The first paper describes a new control strategy for avoiding overflow metabolism in the exponential growth phase of a fermentation, based on analysis of the frequency spectrum of the dissolved oxygen measurement following a periodic perturbation in the feed rate.

7. 10. Contributions to Specification, Implementation, and Execution of Secure Software

   Författare :John Wilander; Mariam Kamkar; Benjamin Livshits; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis contributes to three research areas in software security, namely security requirements and intrusion prevention via static analysis and runtime detection.We have investigated current practice in security requirements by doing a field study of eleven requirement specifications on IT systems.
