  In these times, with the development of the world, biometric identification systems are becoming more and more widespread. Access control systems, but even the most mid-range smartphones have biometric authentication features, and even ID cards can include a person's fingerprint. The research group previously realized a rudimentary gait recognition system, which was upgraded to a multicamera system with high-resolution cameras and instead of reference points, the new version recognizes different templates. The program can compare and evaluate the functions that are matched to the reference curve and the current curve in a specific way, whether two walking images are identical. The comparison is decided by the definite integrals of the two suited functions. The self-developed gait recognition system was tested by the research team on several test subjects and according to the results, permission was never given to a strange person.

  In case of screening and tracking conditions of patients [20] with spinal deformities it is very important to develop an examination method that does not load patinets’ body with harmful radiation. This method is based on the moiré effect. Pictures were taken from patients’ back and information could be obtained about the back’s condition. A computer algorithm is under development that can produce the sagittal line of the spine from moiré images. This program is being tested with Scheuermann disease patients.

  As it is well known, an accurate knowledge of solar photovoltaic (PV) cell parameters from experimental data is of major importance for estimate their performances and to implement high energetic efficiency PV plants. In the last decade several solar cell models, respectively a high amount of software toolkits have been developed to evaluate their electrical behavior and performances. This paper is focused to introduce a LabView graphical programming language based solution to conveniently modeling, simulate, and evaluate solar PV cells energetic efficiency. By using their well known electrical equivalent circuits a fast and accurate PV simulator has been designed and implemented for research and energetic efficiency studies. The simulation models used has been validated through comparison of the obtained characteristics with the ones given by the manufacturers of PV panels. The computer-aided simulation results carried out are in a good agreement with the manufacturer’s catalogue data and the LabView-based program can serve as a very useful toolkit for engineers or researchers who require an accurate PV simulator and evaluate the performances of any photovoltaic module.
