Opis:
The RELAP5/MOD3 input data model of the MARIA research reactor has been developed to provide the capability for the analysis of the reactor core under loss of flow and reactivity insertion transients. The model was qualified against the reactor data at steady state conditions and, additionally, against the existing reliable experimental data for a transient initiated by the reactor scram. The results obtained with the code agree well with the experimental data. The RELAP transient simulation was performed for loss of forced flow accidents including two scenarios with protected and unprotected (no scram) reactor core. Calculations allow estimating time margin for reactor scram initiation and reactivity feedbacks contribution to the results. The presented input data model should be treated as the first step for developing of the model including the whole primary cooling circuit of the reactor.

Opis:
In this work results of investigations concerning nanostructuring of polymers and some other solids using a laser-plasma extreme ultraviolet source are presented. The plasma radiation was produced using a gas puff target and focused with a gold-plated grazing incidence ellipsoidal collector. Decomposition process of polymers was investigated using a quadrupole mass spectrometer. Different kinds of micro- and nanostructures created in near-surface layers of the materials were investigated using scanning electron microscope. Forms of the structures depend on a particular material and the extreme ultraviolet exposure. In case of some polymers even a single shot is sufficient for creation of the visible changes in surface morphology. In case of inorganic solids visible changes require usually the exposure with tens or hundreds of extreme ultraviolet pulses.

Opis:
Laser plasma with temperature of the order of tens eV can be an efficient source of extreme ultraviolet (EUV). The radiation can be focused using different kind of optics, giving sufficient fluence for some applications. In this work we present results of investigations concerning applications of a laser plasma EUV source based on a double stream gas puff target. The source was equipped with two different grazing incidence collectors. One of them was a multifoil collector, the second one was an axisymmetrical ellipsoidal collector. The multifoil mirror was used mainly in experiments concerning micromachining of organic polymers by direct photo-etching. The experiments were performed for different polymers that were irradiated through a fine metal grid as a contact mask. The smallest element of a pattern structure obtained in this way was 5 μm, while the structure height was 50 μm giving an aspect ratio about 10. The laser-plasma EUV source equipped with the axisymmetrical ellipsoidal collector was used for surface modification of organic polymers and inorganic solids. The surface morphology after irradiation was investigated. Different forms of micro- and nanostructures were obtained depending on material and irradiation conditions.

Opis:
Limb physical movements disability is the result of illnesses or serious injuries, impaired execution of daily activities and limitations or even inability to perform working activity. Restoration of fitness in such cases is possible through rehabilitation that requires arduous repetition of appropriate exercises with participation of an experienced physiotherapist. Exercises using the robot to repeat movements would speed up the process of rehabilitation. The paper presents the concept of rehabilitation robot control system realizing a specified purpose.
Niepełnosprawność ruchowa kończyn powstała w wyniku przebytych chorób lub doznanych urazów, upośledza wykonywanie czynności codziennych i ogranicza a czasem uniemożliwia aktywność zawodową. Przywracanie sprawności w takich przypadkach polega między innymi na przeprowadzeniu rehabilitacji wymagającej żmudnego powtarzania odpowiednich ćwiczeń przy udziale doświadczonego fizjoterapeuty. Ćwiczenia z zastosowaniem robota do powtarzania ruchów rehabilitacyjnych pozwoliłyby ułatwić proces rehabilitacji. Praca przedstawia koncepcje systemu sterowania robota rehabilitacyjnego realizującego wymieniony cel.

Opis:
In 2011 ITAM has completed work conducted with WIML's representatives to develop a comprehensive method of psycho-physiological pilots' signals and external environmental parameters during a test flight. It has been assumed that data will be collected "off line" during a training flight and stored in the monitoring module's memory, and after the flight it will be loaded to the operator's station system at the airport. The "On line" transmission of chosen parameters directly into a database and ongoing observation have also been anticipated. One of the main assumptions for the system was its independent work from the avionics systems of aircraft used for training. This has made it possible to use the system regardless the type of aircraft equipment and without having the necessity to stringent criteria of aviation hardware acceptance. The recording system has been designed as a distributed system consists of modules carried by the pilot, those placed permanently in the cockpit of the plane, a station for test flight preparation and reading recorded data, as well as a database system accessible via the Internet. Communication between the various system modules is to employ various transmission systems, wired as well as wireless. For safety reasons wireless communication between modules in the cockpit was not used in flight, with the exception of GSM transmission used to transfer selected data directly to the Central Acquisition System.

Opis:
ITAM completed work on developing a prototype of the system designed to monitor and conduct cardiac rehabilitation at home. In the course of project execution, a number of devices have been made or adapted to work within the system. The primary problem to be solved was to develop a way of communication for these devices, which would allow the transmission of necessary data in a way that would be convenient for the patient and provide the staff supervising the patient with easy access to this data. Ensuring correct operation the system required a variety of cooperating transmission systems to be used. Communication within the apartment utilizes a wireless network based on a Bluetooth link. The parent node of this network is the Base Station, which is also an intermediary for communication between devices within the apartment and the Centre for Monitoring and Communications. The main module carried by the patient is the ECG module that, in addition to its measurement function, serves as a personal area network node based on elements of the ANT standard supporting the Messenger carried by the patient. This module is also tasked with supervising the patient outside the apartment, making communication with the Centre possible via a GSM/GPRS network. The Base Station exchanges information with the Monitoring and Communication Centre located on a server via the Internet. Access for the patient's doctor or support worker to the Monitoring Centre is possible from any computer with access to the Internet by logging onto the Centre's server.

Opis:
Soft X-ray contact microscopy potentially allows imaging of wet living biological specimens at a spatial resolution higher than optical microscopy and without many of the constraints of scanning electron microscopy. In this paper, we present the development of a laboratory scale contact microscope that uses a laser produced plasma soft X-ray source. The source is based on a double-stream gas-puff target approach and it operates in the "water window" spectral range which enables to capture images of biological samples with a natural contrast. In the preliminary experiments the contact microscope system has been used for imaging of fixed and dried non-malignant HCV29 human bladder cell lines cultured on polymethyl methacrylate photoresists. The samples were exposed with 150 pulses of soft X-rays as an initial test to demonstrate the possibility of image formation. The soft X-ray contact images registered in the photoresists exhibit high resolution in the atomic force microscopy topography which indicates the potential application of soft X-ray contact microscopy in life science to examine small features as small as few tens of nm. The technique could also be used for living cell imaging with further optimization of the microscope system and development of a special specimen holder. The details of the soft X-ray contact microscopy technique and the experimental results are presented and discussed.
