  2. 1. Removal of ultrafine particles by intermediate air filters in ventilation systems. Evaluation of performance and analysis of applications

    Author : Bingbing Shi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurements; ultrafine particles; lifetime cost; indoor air quality; health effect; air cleaning; particle source; modelling; intermediate filter; filter standard;

    Abstract : Epidemiological and toxicological studies demonstrate that ultrafine particles (UFPs) are strongly related with respiratory and cardiovascular diseases and syndromes. One common method to reduce human exposure to particulate air pollution is the use of intermediate class filters (F5-F9 class filters according to EN779:2002). READ MORE

  4. 2. Techniques to Reduce Inefficiencies in Hardware Transactional Memory Systems

    Author : Mridha Mohammad Waliullah; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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). READ MORE

  5. 3. Eulerian-Lagrangian modeling of particle motion in exhaust gas aftertreatment systems

    Author : Henrik Ström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea-SCR; particle trapping; flow-through filter; urea decomposition; diesel particulate matter; particle motion; particle filter; AdBlue-spray; Eulerian-Lagrangian modeling;

    Abstract : In the work to design and optimize new aftertreatment system devices for NOx reduction and particulate matter removal in lean engine exhaust (such as diesel exhaust), it is of great help to be able to perform quick, robust and reliable computer simulations of system performance. A suitable platform for such simulations is Computational Fluid Dynamics (CFD) software. READ MORE

  6. 4. Virus retentive filter paper for processing of plasma-derived proteins

    Author : Lulu Wu; Albert Mihranyan; Margareta Krabbe; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma-derived biologics; human serum albumin; human plasma-derived immunoglobulin; virus removal filtration; Cladophora cellulose; quality control; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : The studies in the present thesis explored the feasibility of using nanocellulose-based filters in virus removal filtration of plasma-derived proteins. In Paper I, two-step nanofiltration of commercially available human serum albumin (HSA) product, which was diluted to 10 g L-1 by phosphate buffer saline (PBS) and adjusted pH to 7.

  7. 5. Leveraging Existing Microarchitectural Structures to Improve First-Level Caching Efficiency

    Author : Ricardo Alves; David Black-Schaffer; Stefanos Kaxiras; Mattan Erez; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Energy Efficient Caching; Memory Architecture; Single Thread Performance; First-Level Caching; Out-of-Order Pipelines; Instruction Scheduling; Filter-Cache; Way-Prediction; Value-Prediction; Register-Sharing.;

    Abstract : Low-latency data access is essential for performance. To achieve this, processors use fast first-level caches combined with out-of-order execution, to decrease and hide memory access latency respectively. READ MORE
