    • Power saturation in standard and double-AR unfolded laser diode cavities 

      Peters, M. G.; Fily, A.; Rossin, V.; Demir, Abdullah (IEEE, 2016)
      We report modeling and experimental results that demonstrate mechanisms limiting the output power of broad area semiconductor lasers. The modeling comprises numerical simulations of the laser cavity with evolution of ...
    • Power series having tails with only real nonpositive zeroes 

      Ostrovskii, Iossif Vladimirovich (Elsevier Masson, 1997)
      If for all sufficiently large n the nth tail of the power series of an entire function f has only real nonpositive zeroes, then log M(r, f) ≤ 1/2 log 2(log r)2 + O(log r), r → ∞. This bound is close to the best possible.
    • Power spectrum equalized scalar representation of wide-angle optical field propagation 

      Külçe, Onur; Onural, Levent (Springer New York LLC, 2018)
      It may be desirable to represent optical fields using scalar approximations, due to its simplicity. Since the optical field is an electromagnetic wave, in order to implement an optical setup, a mapping from such a scalar ...

    • Power-source-aware adaptive routing in wireless sensor networks 

      Tekkalmaz, Metin (Bilkent University, 2013)
      A wireless sensor network (WSN) is a collection of sensor nodes distributed over an area of interest to accomplish a certain task by monitoring environmental and physical conditions and sending the collected data to a ...
    • Power-source-aware backbone routing in wireless sensor networks 

      Tekkalmaz, Metin; Körpeoğlu, İbrahim (IEEE, 2010-11)
      Due to the limited energy-source and mostly unattended nature of the wireless sensor networks, efficient use of energy has a critical importance on the lifetime of the applications accomplished by such networks. Although ...
    • Powerful nonparametric seasonal unit root tests 

      Eroğlu, B. A.; Göğebakan, K. Ç.; Trokić, M. (Elsevier B.V., 2018)
      This paper introduces a powerful nonparametric testing procedure for seasonal unit roots by utilizing the fractional integration operator. Different from the well-known seasonal unit root tests of Hylleberg et al. (1990), ...
    • A powerful test for unit root and an application to GNP of seven OECD countries 

      Ustundag, Aliye (Bilkent University, 2000)
      This thesis uses a powerful test, Dickey-Fuller Generalized Least Squares (DF-GLS), to see whether unit root exists or not in real GNP of OECD Countries - Australia, Canada, Germany, Japan, Italy, U.K. and U.S. - for ...
    • Powers and the mind-body problem 

      Aranyosi, I. (2010)
      This paper proposes a new line of attack on the conceivability argument for mind-body property dualism, based on the causal account of properties, according to which properties have their conditional powers essentially. ...
    • PPAR-alpha L162V polymorphism in human hepatocellular carcinoma 

      Koytak, E. S.; Mızrak, D.; Bektaş, M.; Verdi, H.; Arslan-Ergül, Ayça; İdilman, R.; Çınar, K.; Yurdaydın, C.; Ersöz, S.; Karayalçın, K.; Uzunalimoğlu, Ö.; Bozkaya, H. (Turkish Society of Gastroenterology, 2008)
      Background/aims: Several lines of evidence suggest that peroxisome proliferator-activated receptor alpha may be involved in hepatocarcinogenesis. L162V polymorphism of the peroxisome proliferator-activated receptor alpha ...
    • Practical and realistic animation of cloth 

      Bayraktar, Serkan; Güdükbay, Uğur; Özgüç, Bülent (IEEE, 2007-05)
      In this paper, we propose a system for the practical animation of cloth materials. A mass spring based cloth model is used. Explicit time integration methods are used to solve the equations of motion. We update the spring ...
    • Practical multi-featured perfect absorber utilizing high conductivity silicon 

      Gok, A.; Yilmaz, M.; Bıyıklı, N.; Topallı, K.; Okyay, A., K. (Institute of Physics Publishing, 2016)
      We designed all-silicon, multi-featured band-selective perfect absorbing surfaces based on CMOS compatible processes. The center wavelength of the band-selective absorber can be varied between 2 and 22 μm while a bandwidth ...
