    • A Two-dimensional Search used with a Non-Linear least Squares Solver 

      Bartholomew-Biggs, M.; Forbes, A.B. (2000)
      This note describes a modified search strategy for use with a Gauss-Newton method for nonlinear least-squares problems. If a standard line search along the Gauss-Newton vector p is unable to make much progress, a new search ...
    • A Two-dimensional Splashing Model for Investigating Impingement Characteristics of Supercooled Large Droplets 

      Wang, C; Chang, S; Leng, M; Wu, Hongwei; Yang, B (2016-04-01)
      In this article, a two-dimensional (2D) splashing model is proposed to investigate the dynamics when supercooled large droplets (SLD) impinging on a wall surface in the aircraft-icing field. Energy conservation for droplet ...
    • Two-level branch prediction using neural networks 

      Egan, C.; Steven, G.B.; Quick, P.; Anguera, R.; Steven, F.L.; Vintan, L. (2003)
      Dynamic branch prediction in high-performance processors is a specific instance of a general time series prediction problem that occurs in many areas of science. Most branch prediction research focuses on two-level adaptive ...
    • Two-Level Reinforcement Learning Framework for Self-Sustained Personal Robots 

      Fujii, Koyo; Holthaus, Patrick; Samani, H; Premachandra, Chinthaka; Amirabdollahian, Farshid (Springer Nature, 2023-12-03)
      As social robots become integral to daily life, effective battery management and personalized user interactions are crucial. We employed Q-learning with the Miro-E robot for balancing self-sustained energy management and ...
    • A two-phase qualitative enquiry into storytelling’s potential to support palliative care patient-led change, using a systematic review approach 

      Roberts, Amanda (2024-01-09)
      A terminal diagnosis can diminish an individual’s sense of agency and identity. Leading change appears to restore a sense of agential self. The first phase of this literature review explores factors influencing patient-led ...
    • A two-stage approach of manufacturing FeAl40 iron aluminides by self-propagating synthesis and pressureless sintering 

      Zhang, Zhenxue; Chrysanthou, Andreas (2018-08-08)
      A two-stage sintering process was successfully used to sinter FeAl to densification levels of just above 95% at a temperature of 1300 ºC. In the first stage, mixed iron and aluminium powders were synthesised at 750°C via ...
    • Type Ia supernova progenitors, lifetime, and cosmic supernova rate 

      Kobayashi, C.; Nomoto, K. I. (Springer Nature, 2003)
      We make a comparison of the lifetime distribution derived from several models of Type Ia Supernovae (SNe Ia) and evaluate the SN Ia models from the observational constraints. Our SN Ia model, which is based on the single ...
    • Type Ia supernovae : Progenitors and diversities 

      Nomoto, K.; Uenishi, T.; Kobayashi, C.; Umeda, H.; Ohkubo, T.; Hachisu, I.; Kato, M. (Springer Nature, 2003)
      A key question for supernova cosmology is whether the peak luminosities of Type Ia supernovae (SNe Ia) are sufficiently free from the effects of cosmic and galactic evolution. To answer this question, we review the currently ...
    • Type Ia supernovae and chemical evolution of galaxies 

      Nomoto, K; Umeda, H; Kobayashi, Chiaki (Wolters Kluwer, 2002)
      The cosmic/galactic chemical evolutions have been modeled with the early metal enrichment by Type II supernovae (SNe II) and the delayed enrichment of Fe by Type Ia supernovae (SNe Ia). However, the exact nature of SN Ia ...
    • Type Ia supernovae: Progenitors and evolution with redshift 

      Nomoto, K; Umeda, H; Hachisu, I; Kato, M; Tsujimoto, T; Kobayashi, Chiaki (American Institute of Physics (AIP), 2000)
      Relatively uniform light curves and spectral evolution of Type Ia supernovae (SNe Ia) have led to the use of SNe Ia as a "standard candle" to determine cosmological parameters. Whether a statistically significant value of ...
    • Type Image 

      Brownie, Barbara (Gingko Press, 2011)
      One of the most comprehensive surveys of type ever published, Type Image showcases contemporary works that challenge the type/image divide. Letters, words, and phrases in Type Image are playfully crafted into landscapes, ...
    • Type Object 

      Brownie, Barbara (Artpower International, 2014-02)
      Type Object is an intriguing collection of letters, but not as we know them; this collection takes letters into the third dimension using three dimensional design to re-define and re-interpret the meaning of letters that ...
    • Typographic Parallax in Environmental Space : Real and unreal depth and transformation in temporal typography 

      Brownie, Barbara (2013-06-18)
      Recent treatment of onscreen typographic environments interpret virtual space as environmental. Environmental space imitates the properties of reality, allowing recreation of processes such as navigation, and the subsequent ...
    • Typography in Space and Time 

      Hillner, Matthias (2008-11-21)
    • A typology of educationally focused medical simulation tools 

      Alinier, Guillaume (2007)
      Simulation is becoming more commonly used for initial training purposes as well as for continuing professional development, but people often have very different perceptions of the definition of the term simulation, especially ...
    • Ubiquitous Design Studio. Using New Technologies to understand the Contemporary City
