• Design and Evaluation of the Compact and Autonomous Energy Subsystem of a Wave Energy Converter

  Publikacja

  • M. Drzewiecki
  • J. Guziński

  - ENERGIES - Rok 2023

  This paper presents the results of the design process focused on the development of the energy subsystem (ES) of a wave energy converter (WEC). The ES is an important electrical part that significantly affects the energy reliability and energy efficiency of the entire WEC device. The designed ES was intended for compact WECs powering IoT network devices working in the distributed grid. The developed ES is an electronic circuit...

• An Ultra-Low-Energy Analog Comparator for A/D Converters in CMOS Image Sensors

  Publikacja

  • W. Jendernalik

  - CIRCUITS SYSTEMS AND SIGNAL PROCESSING - Rok 2017

  This paper proposes a new solution of an ultra-low-energy analog comparator, dedicated to slope analog-to-digital converters (ADC), particularly suited for CMOS image sensors (CISs) featuring a large number of ADCs. For massively parallel imaging arrays, this number may be as high as tens-hundreds of thousands ADCs. As each ADC includes an analog comparator, the number of these comparators in CIS is always high. Detailed analysis...

• Preload monitoring in a bolted joint using Lamb wave energy

  Publikacja

  • R. Kędra
  • M. Rucka

  - Bulletin of the Polish Academy of Sciences-Technical Sciences - Rok 2019

  The knowledge of the load in prestressed bolted connections is essential for the proper operation and safety of engineering structures. Recently, bolted joints have become an area of intensive research associated with non-destructive diagnostics, in particular in the context of wave propagation techniques. In this paper, a novel procedure of bolt load estimation based on the energy of Lamb wave signals was proposed. Experimental...

• Design of an Autonomous IoT Node Powered by a Perovskite-Based Wave Energy Converter

  Publikacja

  • M. Drzewiecki
  • J. Guziński

  - Polish Maritime Research - Rok 2023

  This paper presents the results of experimental research focused on wave energy harvesting and its conversion to power Internet of Things (IoT) devices. The harvesting and conversion process was performed using a wave energy converter (WEC) consisting of a lead zirconate titanate piezoelectric ceramic perovskite material and a prototype power electronic circuit. The designed WEC was considered as a power supply for an end node...

• Investigating Fuel Injection Strategies to Enhance Ship Energy Efficiency in Wave Conditions

  Publikacja

  • M. H. Ghaemi
  • H. Zeraatgar
  • M. Barjasteh

  - Polish Maritime Research - Rok 2024

  The prediction of fuel consumption and resulting transportation costs is a crucial stage in ship design, particularly for conditions involving motion in waves. This study investigates the real-time fuel consumption of a container ship when sailing in waves. The overall ship performance is evaluated using a novel non-linear coupled hull-engine-propeller interaction model. A series of towing tank experiments for hull resistance in...
