Dynamic GNSS Mission Planning Using DTM for Precise Navigation of Autonomous Vehicles
PublicationNowadays, the most widely used method for estimating location of autonomous vehicles in real time is the use of Global Navigation Satellite Systems (GNSS). However, positioning in urban environments using GNSS is hampered by poor satellite geometry due to signal obstruction created by both man-made and natural features of the urban environment. The presence of obstacles is the reason for the decreased number of observed satellites...

Constructed wetland systems for aerial runoff treatment in the Gulf of Gdansk region
PublicationW artykule przywołano przykłady udanych wdrożeń obiektów hydrofitowych oczyszczania spływów obszarowych na terenie aglomeracji trójmiejskiej. Zespół obiektów hydrofitowych wybudowany w ZOO w Oliwie wykazał szczególnie wysoką skuteczność usuwania związków azotu. Obiekt hydrofitowy na Potoku Swelina spowodował znaczną poprawę jakości wód Potoku, a co za tym idzie i czystości kąpieliska w rejonie Kamiennego Potoku w Sopocie. Podjęte...

Low-Level Aerial Photogrammetry as a Source of Supplementary Data for ALS Measurements
PublicationThe development of laser scanning technology ALS allows to make high-resolution measurements for large areas result-ing in significant reduction of costs. The main stakeholders at heights data received from the airborne laser scanning is mainly state administration. The state institutions appear among projects such as ISOK. Each point is classified in ac-cordance with the standard LAS 1.2, our research focuses on the class 6 -...

Style Transfer for Detecting Vehicles with Thermal Camera
PublicationIn this work we focus on nighttime vehicle detection for intelligent traffic monitoring from the thermal camera. To train a Convolutional Neural Network (CNN) detector we create a stylized version of COCO (Common Objects in Context) dataset using Style Transfer technique that imitates images obtained from thermal cameras. This new dataset is further used for fine-tuning of the model and as a result detection accuracy on images...

Potential reduction of traffic noise by the means of increased fleet of electric vehicles using a combination of low-noise tyres and low-noise road surfaces
PublicationIn the future, the number of zero-emission vehicles like electric and plug-in hybrid vehicles (in electric mode) is expected to be a substantial part of the vehicle fleet. In Norway, such vehicles already account for approximately 20 % of all new cars sold. Since these vehicles emit negligible noise related to the power-train, the tyre/road noise is the dominating noise source. In the LEO project, tyres designed for such cars have...

Evaluation of energy efficiency of vehicles powered by different fuels
PublicationW pracy przedstawiono nową metodę oceny efektywności energetycznej pojazdów zasilanych różnymi paliwami. Analizę można wykonać na podstawie jednego przejazdu w regularnym ruchu miejskim z rejestracją podstawowych parametrów silnika i pojazdu. Warunki eksploatacji identyfikowane są przy użyciu energochłonności jednostkowej, która uwzględnia zarówno wpływ warunków zewnętrznych jak również styl jazdy kierowcy.

Comparison of energy efficiency of vehicles powered by different fuels
PublicationNajpopularniejsza metoda oceny efektywności energetycznej pojazdów samochodowych polega na porównywaniu przebiegowego zużycia paliwa osiągniętego w warunkach wybranego testu homologacyjnego. Warunki eksploatacji, zdefiniowane za pomocą przebiegów prędkości w czasie, dotyczą najczęściej tylko dwóch kategorii: jazdy miejskiej i pozamiejskiej. Problemy wynikające z takiego sposobu postępowania zostały omówione na przykładzie analizy...

High Efficiency Dual-Active-Bridge Converter with Triple-Phase-Shift Control for Battery Charger of Electric Vehicles
PublicationAn optimal modulation scheme with triple-phase-shift (TPS) control could increase the efficiency in the entire load range for a dual-active-bridge (DAB) converter under wide output voltage range conditions. Therefore, this study proposes a convergent approach to TPS mode selection, coupled with an optimal modulation scheme, ensuring the circuit’s efficiency over the entire range in the realm of a high-power and high-efficiency...

Chapter 8 : Possibilities of operating fuel consumption estimation of vehicles
PublicationPrzedstawiona w pracy metoda umożliwia ocenę eksploatacyjnego zużycia paliwa pojazdu samochodowego dzięki porównaniu zarejestrowanego zużycia paliwa z referencyjnym dla tych samych warunków eksploatacji. Warunki te mogą wynikać zarówno z lokalnej specyfiki ruchu pojazdów jak również ze sposobu prowadzenia auta przez kierowcę. Zgodnie z przyjętą metodą warunki te mogą zostać w bardzo prosty sposób zarejestrowane w czasie codziennej...

Selective monitoring of noise emitted by vehicles involved in road traffic
PublicationAn acoustic intensity probe was developed measures the sound intensity in three orthogonal directions, making possible to calculate the azimuth and elevation angles, describing the sound source position. The acoustic sensor is made in the form of a cube with a side of 10 mm, on the inner surfaces of which the digital MEMS microphones are mounted. The algorithm works in two stages. The first stage is based on the analysis of sound...
