Towards Hybrid Urban Mobility: Kick Scooter as a Means of Individual Transport in the City
PublikacjaThe characteristic feature of a contemporary city is its inconvenience and oppressiveness caused by the hitherto dominant paradigm of urban planning based on car mobility. As a result, the inhabitants have to cope with air pollution, noise, spatial barriers, sedentary lifestyle and other factors which worsen their health and quality of life. Ecological and physically activating urban mobility thus plays an increasingly important...

Sick building syndrome due to molds
PublikacjaThe term Sick Building Syndrome (SBS) is a combination of ailments occurring in a specific building. Building occupants complain of symptoms such as headaches and dizziness, fainting, nausea, irritation of the mucosal membranes, skin irritation and other nonspecific hypersensitivity reactions.One of the SBS causes can be molds, which are ubiquitous in the air (over 400 species). It is estimated that 30% of the health problems (related...

From the multiple frequency tracker to the multiple frequency smoother
PublikacjaThe problem of extraction/elimination of nonstationary sinusoidalsignals from noisy measurements is considered. This problem is usually solved using adaptive notch filtering (ANF)algorithms. It is shown that the accuracy of frequency estimates can be significantly increased if the results obtained from ANF are backward-time filtered by an appropriately designed lowpass filter. The resulting adaptive notch smoothing (ANS)algorithm...

A self-optimization mechanism for generalized adaptive notch smoother
PublikacjaTracking of nonstationary narrowband signals is often accomplished using algorithms called adaptive notch filters (ANFs). Generalized adaptive notch smoothers (GANSs) extend the concepts of adaptive notch filtering in two directions. Firstly, they are designed to estimate coefficients of nonstationary quasi-periodic systems, rather than signals. Secondly, they employ noncausal processing, which greatly improves their accuracy and...

Autonomous pick-and-place system based on multiple 3Dsensors and deep learning
PublikacjaGrasping objects and manipulating them is the main way the robot interacts with its environment. However, for robots to operate in a dynamic environment, a system for determining the gripping position for objects in the scene is also required. For this purpose, neural networks segmenting the point cloud are usually applied. However, training such networks is very complex and their results are unsatisfactory. Therefore, we propose...

Process arrival pattern aware algorithms for acceleration of scatter and gather operations
PublikacjaImbalanced process arrival patterns (PAPs) are ubiquitous in many parallel and distributed systems, especially in HPC ones. The collective operations, e.g. in MPI, are designed for equal process arrival times (PATs), and are not optimized for deviations in their appearance. We propose eight new PAP-aware algorithms for the scatter and gather operations. They are binomial or linear tree adaptations introducing additional process...

The statistical impact of experimental result scatter of asphalt mixtures on their numerical modelling
PublikacjaThe paper presents selected test results of asphalt mixture conducted in low temperatures. The obtained parameters are highly diverse. It concerns ultimate breaking loads, stiffness parameters related to Young's modulus but also the fracture course. Statistical analysis upon the results makes it possible to relevantly estimate the material-defining parameter values. Such a random approach leads to the mean values of breaking and...

Nick Srnicek. Kapitalizm platform.Przekład i opracowanie naukowe: Janusz Grygieńć i Andrzej Karalus
PublikacjaAutor książki dowodzi, że aby zrozumieć współczesną gospodarką należy analizować największe spółki technologiczne, traktując je jako aktorów ekonomiczni w ramach kapitalistycznego systemu produkcji. Punktem wyjścia jest diagnoza, iż w wyniku długotrwałego spadku rentowności produkcji przemysłowej kapitalizm zaczął wykorzystywać dane do tego, żeby utrzymać wzrost gospodarczy oraz witalność, których nie mógł zapewnić sektor produkcyjny....
