Object detection and segmentation are two core modules of an autonomous vehicle perception system. They should have high efficiency and low latency while reducing computational complexity. Currently, the most commonly used algorithms are based on deep neural networks, which guarantee high efficiency but require high-performance computing platforms. In the case of autonomous vehicles, i.e. cars, but also drones, it is necessary to use embedded platforms with limited computing power, which makes it difficult to meet the requirements described above. A reduction in the complexity of the network can be achieved by using an appropriate: architecture, representation (reduced numerical precision, quantisation, pruning), and computing platform. In this paper, we focus on the first factor the use of so-called detection-segmentation networks as a component of a perception system. We considered the task of segmenting the drivable area and road markings in combination with the detection of selected objects (pedestrians, traffic lights, and obstacles). We compared the performance of three different architectures described in the literature: MultiTask V3, HybridNets, and YOLOP. We conducted the experiments on a custom dataset consisting of approximately 500 images of the drivable area and lane markings, and 250 images of detected objects. Of the three methods analysed, MultiTask V3 proved to be the best, achieving 99% mAP(50) for detection, 97% MIoU for drivable area segmentation, and 91% MIoU for lane segmentation, as well as 124 fps on the RTX 3060 graphics card. This architecture is a good solution for embedded perception systems for autonomous vehicles. The code is available at: https://***/vision-agh/MMAR_2023.

In women gender, the highest universal tumor is breast cancer. After lung cancer, breast cancer is more fatal among women. Each year, a massive number of women are affected by breast cancer. Breast cancer is detected by conventional methods such X-ray mammography, magnetic resonance imaging (MRI), ultrasound, and biopsies. Early detection of breast tumour is vital since the progress of breast cancer is crucial for accurate and effective therapy. The exact location and size of the tumour is to be found for the effective therapy in women. Medical procedures have some disadvantages when dealing with the human body. This project uses HFSS software to make two different shapes of breast phantoms, a Microstrip patch antenna in the transmission side, and a Microstrip patch antenna to detect the existence of a malignant tumour in the receiving side. It was decided to create two Microstrip patch antennas, one of which would serve as the transmitter and the other will act as the reception of the electromagnetic waves. Using HFSS software, the breast structure with and without a tumour was produced based on the predefined parameters. Between the receiving and transmitting Microstrip patch antennas lies the breast structure. The nondestructive examination of the biological tissue is possible with this imaging because microwaves are non-ionizing and are less harmful while comparing with the existing techniques available in the real-world scenario. Microwave imaging can precisely pinpoint the location and size of the tumour because the tumour is extremely small in the early stages of breast cancer. Microwave frequency shall be used to detect the tumour since their conductivity and permittivity values will vary while comparing the normal and healthy breast tissues with a human breast tissue that is infected by cancer. Patients don't experience any health problems during this tumour detection procedure because the energy absorbed by the breast while using a Microstrip patch antenna

Offshore wind turbines, with their larger rotors designed to boost power capacity, contend with increased aerodynamic and operational loads. These heightened loads often result in mechanical damage and decreased efficiency. Furthermore, because of variations in wind speed across the rotor, each blade experiences unique loads. These loads can cause fatigue and vibration in the blades, which can impair the blades' performance. The rotor blades' angle of attack with respect to the wind is adjusted by a well-designed pitch controller to minimise these problems and maximise power production. This paper addresses the differences between onshore and offshore wind turbines, nonlinear characteristics of wind turbines and lowers blade loads by presenting an innovative pitch angle controlling approach using fuzzy logic. Three controllers are used to create and assess a mathematical model of the pitch controlling system: PID, Fuzzy and Fuzzy-PID. Simulation results indicate that the Fuzzy-PID controller surpasses other strategies in mitigating uncertainties and disturbances in offshore wind turbine systems. Compared to conventional PID control, the Fuzzy-PID hybrid system demonstrates notable improvements, including a reduced rise time of 0.489 seconds, settling time of 4.327 seconds, overshoot of 6.989%, undershoot of 1.59%, and zero steady-state error. This innovative approach holds promise for enhancing offshore wind turbine efficiency, ensuring sustainable energy production in the face of escalating demands.
