The Concatenation of the Concurrent Self-replication and Self-organization Processes

Wegrzyn S., Znamirowski L., Silesian University of Technology, PL

In the paper the concatenation of the concurrently running two self-replication processes and concurrently running self-replication and self-organization processes has been analyzed and discussed. Basing on the simulation, there was possible to predict the behavior [...]

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 [...]

Engineering of efficient biocatalysts using nanostructured mesoporous silicate carriers

Szymanska K., Bryjak J., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Science, PL

Immobilization of free enzymes/proteins on water-insoluble mesoporous silica (MS) supports is often applied to obtain efficient biocatalysts for various applications. Three methods were applied for enzyme bonding onto MS: (1) physical adsorption with subsequent crosslinking [...]

Investigations on the convective heat transfer in Ag – and Cu – ethylene glycol nanofluids

Dzido G., Chmiel-Kurowska K., Gierczycki A., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Science, PL

Common coolants as water, oil or ethylene glycol are characterized by poor thermal properties, i.e. convective heat transfer and heat conductivity coefficient. Addition of solid particles with size less than 100 nm can significantly improve [...]

Silica-alumina composite monoliths with a hierarchical pore structure containing the MFI-type zeolitic films

Pudlo W., Pashkova V., Derewinski M., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Sciences, PL

Materials with multimodal hierarchical porosity, containing pore networks in the range of micro-, meso- and macropores, attract considerable attention owing to their widespread application prospects in process industries (catalysts, sorbents), energy conversion and sensors. Here [...]

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 [...]

Molecular Synergy in the Nano-networks

Znamirowski L., Silesian University of Technology, PL

Technology heterogeneity in the products or object fabrication system, where the external control system usually is based on silicon technology, the interface e.g. transducers or robots represents mixed technology, and the controlled process another, leads [...]

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 [...]
