  • Lohan, Elena Simona; Seco-Granados, Gonzalo (2013)
    A Carrier-to-Noise spectral density-based criterion for selecting Binary Offset Carrier signals (both sine and cosine) for the purpose of a cognitive tracking unit is derived in this letter. The paper presents the C/N0 gap ...
  • Gurtovenko, Andrey A.; Vattulainen, Ilpo (2009)
    The electrostatic properties of lipid membranes are of profound importance as they are directly associated with membrane potential and, consequently, with numerous membrane-mediated biological phenomena. Here we address a ...
  • Muller, Juliane; Kanniainen, Juho; Piche, Robert (2013)
    This paper investigates a global optimization algorithm for the calibration of stochastic volatility models. Two GARCH models are considered, namely the Leverage and the Heston-Nandi model. Empirical information on option ...
  • Rodriquez, Francisco J.; Wang, Fu Xiang; Kauranen, Martti (2008)
    A two-beam second-harmonic generation technique is developed to calibrate the magnitude of the second-order nonlinear optical susceptibility components of surface and bulk (multipolar origin) of isotropic materials. The ...
  • Kärkkäinen, Hannu; Jussila, Jari; Multasuo, Jani (2012)
    The aim of this research is to explore the use of crowdsourcing especially from business-to-business companies‟ innovation perspective, and to create a more comprehensive picture of the possibilities of crowdsourcing for ...
  • Rantanen, Ville; Kumpulainen, Pekka; Venesvirta, Hanna; Verho, Jarmo; Spakov, Oleg; Lylykangas, Jani; Vetek, Akos; Surakka, Veikko; Lekkala, Jukka (2013)
    A wide range of applications can benefit from the measurement of facial activity. The current study presents a method that can be used to detect and classify the movements of different parts of the face and the expressions ...
  • Rantanen, Ville; Kumpulainen, Pekka; Venesvirta, Hanna; Verho, Jarmo; Spakov, Oleg; Lylykangas, Jani; Vetek, Akos; Surakka, Veikko; Lekkala, Jukka (2012)
    A wide range of applications can benefit from the measurement of facial activity. The current study presents a method that can be used to detect the movements of different parts of the face and expressions that they form. ...
  • Rantanen, Ville; Niemenlehto, Pekka-Henrik; Verho, Jarmo; Lekkala, Jukka (2010)
    A capacitive facial movement detection method designed for human-computer interaction is presented. Some point-and-click interfaces use facial electromyography for clicking. The presented method provides a contactless ...
  • Rantanen, Ville; Venesvirta, Hanna; Spakov, Oleg; Verho, Jarmo; Vetek, Akos; Surakka, Veikko; Lekkala, Jukka (2013)
    The measurement of the intensity of facial muscle activity can be used in several applications such as human–computer interaction and behavioural science. A new method for the intensity measurement is presented. It is based ...
  • Huhtamäki, Jukka; Nykänen, Ossi; Salonen, Jaakko (2009)
    Modern Web introduces new means to support conference information retrieval and, moreover, social tools that enable conference delegates to actively contribute to a conference. Simultaneously, existing case studies show ...
  • Salonen, Jaakko; Huhtamäki, Jukka; Nykänen, Ossi (2013-10-01)
    Diverse data about various phenomena are implicitly available in the modern web. In particular websites categorized as social media provide rich and heterogeneous data about various entities such as people, corporations, ...
  • Tapaninen, Aija; Seppänen, Marko; Mäkinen, Saku (2009)
    Purpose – This paper investigates the criteria influencing the adoption of innovation in the empirical context of renewable residential energy solutions, particularly the wood pellet heating system. Design/methodology/approach ...
  • Tapaninen, Aija; Seppänen, Marko; Mäkinen, Saku (2009)
    Annually billions of Euros are spent globally on developing a range of green technologies, including bio heating technologies, as part of a push into the renewable energy market. This paper considers customer perceived ...
  • Moradi, Elham; Björninen, Toni; Ukkonen, Leena; Rahmat-Samii, Yahya (2012-11)
    Wearable RFID tags and wireless sensors can be used for on-body and human monitoring applications. Embroidery with conductive thread provides compelling means for the fabrication of seamlessly garment-integrable antennas ...
  • Husu, Hannu; Canfield, Brian K.; Laukkanen, Janne; Bai, Benfeng; Kuittinen, Markku; Turunen, Jari; Kauranen, Martti (2008)
    Second-harmonic generation from T-shaped gold nanodimers with nanogaps has different efficiencies for left- and right-hand circularly polarized fundamental light. The difference arises from the chiral symmetry breaking of ...
  • Lee, H.; Huttunen, Mikko J.; Hsu, K.-J.; Partanen, Mari; Zhuo, G.-Y.; Kauranen, Martti; Chu, S.-W. (2013)
    We provide evidence that the chirality of collagen can give rise to strong second-harmonic generation circular dichroism (SHG-CD) responses in nonlinear microscopy. Although chirality is an intrinsic structural property ...
  • Canfield, Brian K.; Kujala, Sami; Laiho, Kaisa; Jefimovs, Konstantins; Turunen, Jari; Kauranen, Martti (2006)
    The symmetry of metal nanostructures may be broken by their overall features or small-scale defects. To separate the roles of these two mechanisms in chiral symmetry breaking, we prepare gold nanostructures with chirality ...
  • Martinez-Seara, Hector; Rog, Tomasz; Karttunen, Mikko; Vattulainen, Ilpo; Reigada, Ramon (2010)
    Background: In lipid bilayers, cholesterol facilitates the formation of the liquid-ordered phase and enables the formation of laterally ordered structures such as lipid rafts. While these domains have an important role in ...
  • Jääskeläinen, Pekka; Salminen, Erno; Sanchez de La Lama, Carlos; Takala, Jarmo; Ignacio Martinez, Jose (2011)
    Contemporary embedded systems are often designed as Multiprocessor System-on-Chips (MPSoC) which include multiple processors and other peripherals on a single chip. In contrast to general purpose multiprocessors, the design ...
  • Murtola, Teemu; Falck, Emma; Karttunen, Mikko; Vattulainen, Ilpo (2007)
