  1. 1. Ultra-low Power Design Approaches in Memories and Assist Techniques

    Författare :Babak Mohammadi; Integrerade elektroniksystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory; SRAM; assist technique; charge pump; ULP; ULV;

    Sammanfattning : The need for more functionality and higher performance has increased the number of transistors to billions in current processors. A high number of transistors on the same chip area increases the power density, which in turn heats up the devices and lowers the life time of batteries. LÄS MER

  3. 2. Construction of Adaptive Multistep Methods for Problems with Discontinuities, Invariants, and Constraints

    Författare :Fatemeh Mohammadi; Numerisk analys; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multistep methods; Initialization; beta-blocking; Discontinuity; Time adaptivity; Strong stability preserving; Differential algebraic equations;

    Sammanfattning : Adaptive multistep methods have been widely used to solve initial value problems. These ordinary differential equations (ODEs) may arise from semi-discretization of time-dependent partial differential equations(PDEs) or may combine with some algebraic equations to represent a differential algebraic equations (DAEs).

  4. 3. Genetics of primary immunodeficiency diseases

    Författare :Javad Mohammadi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HLA Antigens; IgA deficiency; Common variable immunodeficiency; immunogenetics; immunodeficiency; TACI;

    Sammanfattning : Selective IgA deficiency (IgAD) (serum IgA concentration of T), which abolished expression of the TACI molecule. In addition, we found the previously recognized C104R and C172Y mutations in a heterozygous form in 2 patients with CVID and one, novel, heterozygous P42T mutation. LÄS MER

  5. 4. Comorbidity in risk and outcome of hematological malignancies

    Författare :Mohammad Mohammadi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hematological malignancies are a group of neoplasms that originate from the bone marrow or lymphatic tissues representing close to 10% of the overall cancer burden in the world. Clinical course, prognosis and survival varies greatly from very aggressive disease requiring intensive systemic chemotherapy-based treatment to indolent forms without need of therapy at diagnosis.

  7. 5. Probabilistic time estimation in tunnel projects

    Författare :Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Larsson Stefan; Anna Kadefors; Lars-Olof Dahlström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cost overrun; Tunneling projects; Probabilistic approaches; time estimation; Kostnadsöverskridande; tunnelprojekt; sannolikhetsmetoder; tidsuppskattning; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Transport infrastructure projects, including tunneling, suffer from timedelays and cost overrun. A literature review shows that the effect ofuncertainty has been neglected in explaining time and cost overrunmeaning that technical explanations matter. LÄS MER
