Study on Application of Piezoelectric Vibration Energy Harvesters for Powering of Wireless Sensor Nodes in Large Rotary Machine Diagnostic Systems

Pekoslawski B., Pietrzak P., Makowski M., Szafoni L., Napieralski A., Technical University of Lodz, PL

A condition monitoring of large rotary machines such as turbogenerators in power plants can be more convenient and less expensive when using a distributed measurement system with wireless sensor nodes. A battery-based powering of these [...]

Test ASIC for Real Time Estimation of Chip Temperature

Szermer M., Kulesza Z., Janicki M., Napieralski A., Technical Univiversity of Lodz, PL

The main goal of this paper is to present in detail the design and operation of an ASIC, which will be used in the research aimed at the development of a real time temperature monitoring [...]

Adaptive Subband Filtering Method for MEMS Accelerometer Noise Reduction

Pietrzak P., Pekoslawski B., Makowski M., Napieralski A., Technical University of Lodz, PL

The main factor that determines the cost of vibration-based condition monitoring system of large rotating machines is the unitary price of the piezoelectric sensors, commonly used in such devices. Silicon microaccelerometers can be considered as [...]

Design of Radiation Tolerant Readout System for an Integrated SRAM Based Neutron Detector

Malinowski P., Makowski D., Jablonski G., Napieralski A., Technical University of Lodz, PL

This paper presents a design of a radiation tolerant readout system for an SRAM-based neutron detector. The radiation tolerance has been achieved on the system level by applying Error Detection and Correction schemes. The constructed [...]

Electromechanical System for Lorentz Force Compensation

Sekalski P., Napieralski A., Simrock S., Technical University of Lodz, PL

The cavity is the main element of each linear accelerator used for high-energy physics purpose. The resonant frequency of cavities depends on its shape. Due to the pulse operation they are deformed by dynamic Lorentz [...]

Research of Fault-Tolerant Computing Using COTS Elements

Swiercz B., Makowski D., Napieralski A., Technical University of Lodz, PL

The problem of designing hardened systems is very important for modern physics. The physics experiences design in linear accelerators and synchrotrons need measurements and control devices, which are under radiation impact. This paper highlights the [...]

FPGA-based Neutron Radiation Tolerant Microcontroller

Makowski D., Jablonski G., Grecki M., Mielczarek J., Napieralski A., Technical University of Lodz, PL

The paper presents a FPGA-based neutron radiation detector using radiation sensitive SRAM as a detector. Its main component is a PIC16C57-compatible microcontroller, described in VHDL. The system has been designed using hardware redundancy, Hamming error [...]

Audio Signal Processing Using Mixed Hardware-Software Approach

Rominski A., Ciota Z., Napieralski A., Technical University of Lodz, PL

In this paper the possibilities of modern audio-processing systems have been described. One of the most important tasks is a proper definition of feature vectors. For example, the long-term spectra vector has been chosen as [...]

Three-Dimensional Reconstruction of the Florid Plaque in variant Creutzfeldt-Jakob Diseases

Zubert M., Napieralska M., Napieralski A., Sikorska B., Liberski P., Grams R., Technical University of Lodz, PL

The Alzheimer, BSE , CJD and vCJD diseases belongs to a group of neurodegenerative diseases characterised by an accumulation of extraneuronal filamentous material consisting of β-sheet proteins of various biochemical properties. Clinically, these diseases manifest [...]

Electro-Static Membrane Model in CAD

Zubert M., Napieralska M., Napieralski A., Department of Microelectronic and Computer Science, PL

The model simplification is one of the most important problems in its design process. Every so often this approach tends to the physical phenomena violation, exceeding assumed domains or published models (and commercial software) application [...]
