    • Angle Estimation for Robotic Arms on Floating Base Using Low-Cost IMUS 

      Zhang,Xiaolong; Peltola,Eelis; Mattila,Jouni (IEEE, 05 / 2018)
      An algorithm that uses low-cost inertial measurement units (IMUs) for estimating link angles for floating base robotic platforms is proposed. Each link has four IMUs attached on its surfaces, and an Extended Kalman Filter ...
    • Beam-based Device Positioning in mmWave 5G Systems under Orientation Uncertainties 

      Rastorgueva-Foi,Elizaveta; Costa,Mário; Koivisto,Mike; Talvitie,Jukka; Leppänen,Kari; Valkama,Mikko (IEEE, 10 / 2018)
      High-accuracy positioning based on angles from multiple base-stations (BSs) requires precise knowledge of the BSs’ orientation. Installation errors are bound to occur in practice, and any mismatch between the actual and ...
    • Binomial Gaussian mixture filter 

      Raitoharju,Matti; Ali-Löytty,Simo; Piché,Robert (02.12.2015)
      In this work, we present a novel method for approximating a normal distribution with a weighted sum of normal distributions. The approximation is used for splitting normally distributed components in a Gaussian mixture ...
    • DoA Estimation Using Compact CRLH Leaky-Wave Antennas : Novel Algorithms and Measured Performance 

      Paaso,Henna; Gulati,Nikhil; Patron,Damiano; Hakkarainen,Aki; Werner,Janis; Dandekar,Kapil R.; Valkama,Mikko; Mammela,Aarne (2017)
      Traditional direction-of-arrival (DoA) estimation algorithms for multi-element antenna arrays are not directly applicable to reconfigurable antennas due to inherent design and operating differences between antenna arrays ...
    • Indirect NOx emission monitoring in natural gas fired boilers 

      Korpela,Timo; Kumpulainen,Pekka; Majanne,Yrjö; Häyrinen,Anna; Lautala,Pentti (01.08.2017)
      New emission regulations will increase the need for inexpensive NOx emission monitoring solutions also in smaller power plants. The objective in this study is to find easily maintainable and transparent but still valid ...
    • Method for Simulating Dose Reduction in Digital Breast Tomosynthesis 

      Borges,Lucas R.; Guerrero,Igor; Bakic,Predrag R.; Foi,Alessandro; Maidment,Andrew D.A.; Vieira,Marcelo A.C. (2017)
      This work proposes a new method of simulating dose reduction in digital breast tomosynthesis (DBT), starting from a clinical image acquired with a standard radiation dose. It considers both signal-dependent quantum and ...
    • Networking and Positioning Co-Design in Multi-Connectivity Industrial mmW Systems 

      Rastorgueva-Foi,Elizaveta; Galinina,Olga; Costa,Mario; Koivisto,Mike; Talvitie,Jukka; Andreev,Sergey; Valkama,Mikko (2020)
      It is commonly understood that highly directional millimeter-wave (mmW) connectivity -- especially in industry-grade scenarios with complex and unpredictable device mobility -- requires a certain degree of structural ...
    • Photogrammetric Multi-Camera Calibration Using An Industrial Programmable Robotic Arm 

      Gonçalves Ribeiro,Laura; Durmush,Ahmed; Suominen,Olli; Gotchev,Atanas
      International Symposium on Image and Signal Processing and Analysis (IEEE, 01.09.2019)
      Calibration of multiple cameras is a critical step in most vision enhancement systems. Target-based calibration approaches are known to provide accurate and stable results. However, they require manually performed capture ...
    • Solar Irradiation Independent Expression for Photovoltaic Generator Maximum Power Line 

      Kolesnik,Sergei; Sitbon,Moshe; Lineykin,Simon; Batzelis,Efstratios; Papathanassiou,Stavros; Suntio,Teuvo; Kuperman,Alon (2017)
      In order to enhance maximum power point tracking (MPPT) speed of photovoltaic generators (PVGs) upon fast irradiation changes, maximum power line (MPL)-based control is often used. MPL is a curve, linking all possible MPP ...
    • Sound Event Envelope Estimation in Polyphonic Mixtures 

      Martín-Morató,Irene; Mesaros,Annamaria; Heittola,Toni; Virtanen,Tuomas; Cobos,Maximo; Ferri,Francesc J.
      IEEE International Conference on Acoustics, Speech and Signal Processing (IEEE, 17.04.2019)
      Sound event detection is the task of identifying automatically the presence and temporal boundaries of sound events within an input audio stream. In the last years, deep learning methods have established themselves as the ...
