  • Assessment of Biomass Energy Sources in Electricity Generation Using Analytic Network Process Method 
    Safari, Mojtaba; Joghataee, Fatemeh; Afsari, Mahtab (Toronto : CCSE, 2016)
    The purpose of this Paper is to assess and select the preferable and optimum biomass energy source using Analytic Network Process (ANP) for making an efficient Policy in Iran electricity generation industry. There are four ...
  • Every finite system of T1 uniformities comes from a single distance structure 
    Heitzig, Jobst (Valencia : Universitat Politecnica de Valencia, 2002)
    Using the general notion of distance function introduced in an earlier paper, a construction of the finest distance structure which induces a given quasi-uniformity is given. Moreover, when the usual defining condition xy ...
  • Geometric calibration of full spherical panoramic ricoh-theta camera 
    Aghayari, S.; Saadatseresht, Mohammad; Omidalizarandi, Mohammad; Neumann, Ingo (Göttingen : Copernicus GmbH, 2017)
    A novel calibration process of RICOH-THETA, full-view fisheye camera, is proposed which has numerous applications as a low cost sensor in different disciplines such as photogrammetry, robotic and machine vision and so on. ...
  • Geometrical adjustment towards the alignment of vector databases 
    Dalyot, S.; Dahinden, Tobias; Schulze, Malte Jan; Boljen, J.; Sester, Monika (Göttingen : Copernicus GmbH, 2012)
    Comparison of geospatial databases presenting similar spatial extent might show substantial differences. This is the consequence of different factors, such as: accuracy, scale, data collection and processing methods, ...
  • Global rotation estimation using weighted iterative lie algebraic averaging 
    Reich, Martin; Heipke, Christian (Göttingen : Copernicus GmbH, 2015)
    In this paper we present an approach for a weighted rotation averaging to estimate absolute rotations from relative rotations between two images for a set of multiple overlapping images. The solution does not depend on ...
  • A Mathematical Modeling for Delivery Time in Dynamic PERT Networks 
    Afsari, Mahtab; Javadi Vasigh, Hesam (Toronto : CCSE, 2016)
    In project management, the main purpose of proposed methods is project scheduling which helps to management and planning. We can calculate a real average of project closure in dynamic PERT networks by identifying a lower ...
  • Multiresolution wavelet analysis applied to GRACE range rate residuals 
    Behzadpour, Saniya; Mayer-Gürr, Torsten; Flury, Jakob; Klinger, Beate; Goswami, Sujata (Göttingen : Copernicus GmbH, 2019)
    For further improvements of gravity field models based on Gravity Recovery and Climate Experiment (GRACE) observations, it is necessary to identify the error sources within the recovery process. Observation residuals ...
  • Publikationen und Gender-Effekte in der Mathematik 
    Mihaljević, Helena; Santamaria, Lucía; Tullney, Marco (2018)
    Die Unterrepräsentation von Frauen in der wissenschaftlichen Mathematik hält trotz steigender Absolventinnenzahlen an. Publikationen sind ein wesentlicher Baustein wissenschaftlicher Karrieren. Deshalb werden sie in unserer ...
  • Research on Teaching and Learning Mathematics at the Tertiary Level: State-of-the-Art and Looking Ahead 
    Biza, Irene; Giraldo, Victor; Hochmuth, Reinhard; Sadat Khakbaz, Azimeh; Rasmussen, Chris (New York, NY : Springer International Publishing, 2016)
    This topical survey focuses on research in tertiary mathematics education, a field that has experienced considerable growth over the last 10 years. Drawing on the most recent journal publication as well as the latest ...
  • Wolf Barth (1942–2016) 
    Bauer, Thomas; Hulek, Klaus; Rams, Slawomir; Sarti, Alessandra; Szemberg, Tomasz (Heidelberg : Springer, 2017)
    In this article we describe the life and work of Wolf Barth who died on 30th; December 2016. Wolf Barth's contributions to algebraic variety span a wide; range of subjects. His achievements range from what is now called ...
