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 [...]

VHDL Simulation considering Single Event Upsets (SEUs)

Grecki M., Technical University of Lodz, PL

The SEEs can be destructive for semiconductor devices, however non-destructive SEE called SEU ( Single Event Upsets) resulting of bit flips seems to be the main problem. Due to reduction of feature size the SEUs [...]

A Principle of Regulating the Collective Effect of Assembling Patterns in a Moderate Number of Equivalent Finite Regular Arrays of Active Nanoelements due to Local Transferring Information by Pairs Hopping under Synchronous Excitation

Kozlowski W., Inst. Biocybernetics & Biomed.Eng. PAS, PL

One reports computational study that reveals a set of general requirements fulfilling of which would afford the opportunity for using changes in ambient conditions to regulate accomplishing the collective outcome (collective effect CE) of evolution [...]

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 [...]

The Application of SRAM Chip as a Novel Neutron Detector

Makowski D., Grecki M., Mukherjee B., Simrock S., Swiercz B., Napieralski A., Technical University of Lodz, Department of Microelectronics and Computer Science, PL

Bremsstrahlung gamma radiation and photoneutrons are generated during the operation of linear accelerators. These parasitic radiations could pose a risk of radiation damage electronic systems placed in the vicinity of accelerator. One can use different [...]

The IAradSim – IA32 Architecture under a High Radiation Environment Simulator

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

Systems, which were designed for military or space applications, very often are exposed to increased radiation. The problem of designing hardened systems is very important for modern physics. The physics experiences design in linear accelerators [...]

Tests of the Sigma-Delta Converter Designed as a Part of Microsystem Dedicated to Water Pollution Monitoring

Szermer M., Napieralski A., Tech. Univ. of Lodz, PL

The presented structure is a result of authors’ research in the 5th European Programme SEWING (System for European Water monitorING). The aim of this project is to elaborate a small, cheap and generally accessible microsystem, [...]

Effective Modelling and Simulation of Over-Heated Actuators

Zubert M., Napieralska M., Napieralski A., Noullet J.L., Technical University of Lodz, PL

A mono-dimensional model of an over heated actuator is presented in this paper. The proposed distributed models are derived based on real physical phenomena described by multi-dimensional partial differential equations. The proposed model has been [...]
