  2. 1. Modelling and optimization of gear shifting mechanism, Application to heavy vehicles transmission systems

    Author : Muhammad Irfan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pareto optimization; synchronization; constraint Lagrangian formalism; sensitivity analysis; Generic synchronizer;

    Abstract : Without an efficient transmission system the idea of an efficient vehicle is incomplete. During running of the vehicle especially in case of heavy vehicles the transmission system has to face different situations during which the system possibly can lose its efficiency. READ MORE

  4. 2. Regulation of productivity in Trichoplusia ni and Spodoptera frugiperda Sf9 serum-free cultures

    Author : Karin Calles; Lena Häggström; Gunnel Dalhammar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Insect cells; BEVS; Spodoptera frugiperda; Sf9; Trichoplusia ni; BTI-Tn-5B1-4; specific productivity; conditioned medium; conditioned medium factors; cell cycle; synchronization; G2 M; Bioteknik; Bioengineering; Bioteknik;

    Abstract : The aim of this work has been to characterize the effects of conditioned medium (CM) on insect cell productivity and physiology in order to get a better understanding about the mechanisms that regulate productivity in serum-free media. Two cell lines have been investigated, Spodoptera frugiperda (Sf9) and Trichoplusia ni (T. ni, BTI-Tn-5B1-4). READ MORE

  5. 3. Effects of abiotic and biotic factors on hatching, emergence and survival in Baltic salmon (Salmo salar L.)

    Author : Eva Brännäs; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic salmon; salmo salar; eggs; egg colour; alevins; fry; photoperiod; temperature; hatching; emergence pattern; synchronization; survival;

    Abstract : This thesis deals with important factors that affect the temporal organization of emergence and early survival of Baltic salmon (Salmo salar L.). The study population was obtained from the Norrfors hatchery (63°50'N,20°05'E), Umeälven (Ume river) in Northern Sweden. READ MORE

  6. 4. Metabolic communication between individual yeast cells

    Author : Martin Mojica Benavides; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolic synchronization; Single-cell; glycolytic oscillations; synchronization waves;

    Abstract : With the recent progress in sensitive cell manipulation and microfabrication techniques, glycolytic oscillations in yeast have been observed at a single-cell level. It was shown that individually, oscillating cells could entrain their phases by periodic external perturbations. READ MORE

  7. 5. Augmenting Transactional Memory with the Future Abstraction

    Author : Jingna Zeng; Seif Haridi; Paolo Romano; Vladimir Vlassov; Keijo Heljanko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Software Transactional Memory; Parallel Programming; Futures; Synchronization; Concurrency Control; Self-tuning; Sequential Model-based Bayesian Optimization; Memória Transacional em Software; Programação Paralela; Futuros; Sincronização; Controle de Concorrência; Auto-ajuste; Otimização Bayesiana Seqeencial Baseada em Modelos; Mjukvarubaserat transaktionellt minne; parallell programmering; futures; synkronisering; parallell exekvering; självjustering; sekventiell modellbaserad Bayesian-optimering; Datalogi; Computer Science;

    Abstract : The advent of multicore systems spurred great interest in Transactional Memory (TM). TM is a parallel programming paradigm that coordinates concurrent threads by incorporating transactions into programming languages. READ MORE
