  1. 1. Roles of SNAP-25 isoforms in activity-dependent long-term synaptic plasticity

    Author : Muhammad Irfan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : SNARE proteins, SNAP-25, syntaxin 1A and VAMP2 constitute the functional units which join together to form the core SNARE complex. The SNARE complex carries out the vital function of membrane fusion of intracellular vesicles with plasma membranes, leading to the release of neurotransmitters in brain neuronal circuits and of hormones in endocrine glands.

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

    Author : Muhammad Irfan; Chalmers University of Technology; []
    Keywords : 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

  3. 3. Modelling, failure modes prediction and optimization of gear shifting mechanism, Application to heavy vehicle transmission systems

    Author : Muhammad Irfan; Chalmers University of Technology; []
    Keywords : failure modes prediction.; gear shifting; GT-Suite modelling; optimization; Synchronizer; constrained Lagrangian formalism; sensitivity analysis;

    Abstract : The transmission system has a key role to drive a vehicle transmitting power from engine to rotational motion at wheels. Gear shifting mechanism inside the gearbox is a crucial part of the transmission system. READ MORE

  4. 4. Variation-Aware System Design Simulation Methodology for Capacitive BCC Transceivers

    Author : Muhammad Irfan Kazim; Jacob Wikner; Svante Signell; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Capacitive body coupled communication (BCC), frequency range 500 kHz to 15 MHz, is considered an emerging alternate short range wireless technology which can meet the stringent low power consumption (< 1 mW) and low data rate (< 100 kbps) requirements for the next generation of connected devices for applications like internet-of-things (IoT) and wireless sensor network (WSN). But a reliable solution for this mode of communication covering all possible body positions and maximum communication distances around the human body could not be presented so far, despite its inception around 20 years back in 1995.

  5. 5. SmCo for polymer bonded magnets : Corrosion, silanization, rheological, mechanical and magnetic properties

    Author : Muhammad Irfan Qadeer; Steven Savage; Mikael Hedenqvist; Uta Klement; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Organofunctional alkoxysilanes; High temperature oxidation; Rare-earth magnetic alloys; SmCo; Isothermal; Non-isothermal; Microstructure; Magnetic properties;

    Abstract : This thesis presents the study of organofunctional alkoxysilane coatings to prevent high temperature oxidation of Sm-Co powders. Sm-Co are important permanent magnetic alloys, owing to their high Curie temperature and large values of magnetocrystalline anisotropy. READ MORE
