Opis:
This paper proposes a biometric system for authentication that uses the retina blood vessel pattern. The retina biometric analyzes the layer of blood vessels located at the back of the eye. The blood vessels at the back of the eye have a unique pattern, from eye to eye and person to person. The retina, a layer of blood vessels located at the back of the eye, forms an identity card for the individual under investigation. In particular retinal recognition creates an ”eye signature” from its vascular configuration and its artificial duplication is thought to be virtually impossible.

Opis:
Thin films of bismuth oxide have been prepared utilizing vacuum evaporation. XRD anyalysis reveal that all the films were tetragonal polycrystalline structure with a preferred orientation along (002) plane. SEM images indicate that the grain size fall in the category of nanosize. AFM results assure that the nanonstructure behavior of thin films. Optical studies show that these films have a direct transition with optical energy gap equal to 2.5 eV.

Opis:
Today's world mainly focuses on reducing human effort and maximizing efficiency. Machines are replacing humans in many hazardous working environments. Automation is playing an important role in saving human efforts in most of their day-to-day works. A robotic vehicle has been developed in this project which can be particularly used in a small scale industry. The robotic vehicle is controlled by a mobile phone that is connected to the robot through a GSM network which acts as a remote controller. DTMF technology is used, which enables the robot to be controlled over the GSM network. The keypad of the mobile phone acts as a remote to control the vehicle's movement. The robotic vehicle developed is not an Automated Guided Vehicle (AGV) as an operator has to manually operate the vehicle. A sensor is attached to the front of the vehicle which senses obstruction in its path and enables the vehicle to avoid collisions with moving or fixed objects. The vehicle features battery powered motors and computer technology that has been programmed to drive to and from specific points. This research work involves the fabrication of a working model vehicle controlled over a GSM network using DTMF technology. The guided vehicle can work in environments such as transporting materials from a warehouse to production lines to reduce human effort and increase efficiency.

Opis:
Fusion, in all its varieties, is a very current subject of science and technology. The results of strongly exothermic reaction of thermonuclear fusion between nuclei of deuterium and tritium are: helium nuclei and neutrons, plus considerable kinetic energy of neutrons of over 14 MeV. DT nuclides synthesis reaction is probably not the most favorable one for energy production, but is the most advanced technologically. More efficient would be possibly an aneutronic fusion. The EU by its EURATOM agenda prepared a Road Map for research and implementation of Fusion as a commercial method of thermonuclear energy generation in the time horizon of 2050. The milestones on this road are tokomak experiments JET, ITER and DEMO, and neutron experiment IFMIF. There is a hope, that by engagement of the national government, and all research and technical fusion and plasma communities, part of this Road Map may be realized in Poland. The infrastructure build for fusion experiments may be also used for material engineering research, chemistry, biomedical, associated with environment protection, power engineering, security, etc. Construction of such research and industrial accelerator and tokomak infrastructure may have potentially a profound meaning for the development of science and technology in Poland.

Opis:
ILC machine–International Liner Collider, is one of two accelerators e+e-just under design and advanced consideration to be built with final energy of colliding electron and positron beams over 1 TeV. An alternative project to ILC is CLIC in CERN The ILC machine is an important complementary addition for the research potential of the LHC accelerator complex. The required length of ILC is minimally 30 km, but some versions of the TDR estimates mention nearly 50km. Superconducting RF linacs will be built using well established 1,3 GHz TESLA technology using ultrapure niobium or Nb3Sn resonant microwave cavities of RRR class, of ultimate finesse, working with gradients over 35MV/m, while some versions of the design mention ultimate confinement as high as 50MV/m. Several teams from Poland (Kraków. Warszawa, Wrocław – IFJ-PAN, AGH, UJ, NCBJ, UW, PW, PWr, INT-PAN) participate in the global design effort for this machine – including detectors, cryogenics, and SRF systems. Now it seems that the ILC machine will be built in Japan, during the period of 2016-2026. If true, Japan will turn to a world super-power in accelerator technology no.3 after CERN and USA. The paper summarizes the state-of-the-art of technical and administration activities around the immense ILC and CLIC machines, with emphasis on potential participation of Polish teams in the global effort of newly established LCC –The Linear Collider Consortium.

WILGA Symposium on Photonics and Web Engineering is well known on the web for its devotion to "young research" promotion under the eminent sponsorship of international engineering associations like SPIE and IEEE. WILGA is supported by the most important national organizations like KEiT PAN and PSP-Photonics Society of Poland. The Symposium is organized since 1998 twice a year. It has gathered over 4000 young researchers and published over 2000 papers mainly internationally, including more than 1000 in 10 published so far volumes of Proc. SPIE. This paper is a digest of WILGA Symposium Series and WILGA 2010 summary.

Opis:
The article describes chosen, yet key parts of newly established European, infrastructural research and development project ARIES (2017-2020) - Accelerator Research and Innovation for European Science and Society, to be realized inside the framework of the H2020 programme. Two institutions from Poland participate in ARIES – these are Warsaw University of Technology and Institute of Nuclear Chemistry and Technology. ARIES is a topical continuation of the previous infrastructural accelerator projects realized uninterruptedly since 2003 – FP6 CARE – Coordinated Accelerator Research in Europe and FP7 TIARA – Test Infrastructure and Accelerator Research Area, EuCARD – European Coordination for Accelerator Research and Development, and EuCARD2. The article is simultaneously a part of a series of papers concerning the participation of Polish doctoral students and young researchers, especially from the Warsaw University of Technology, in large European and world experiments of the discovery class, including building large research infrastructures like: FLASH and EXFEL, ESS, ITER and DEMO, IFMIF, but also satellites built by the ESA, etc. ARIES embraces, among others, the following subjects: energy efficiency and management, cost lowering, miniaturization and ultra-high field gradients, promotion innovation, industrial applications, societal implications, new materials and components, new methods of particles acceleration including laser-plasmaparticles interaction, and building new generations of systems.
