We present a comparative case study of machine learning models, evaluating their efficiency in a practical task of multiclass classification of samples being submissions to a recruitment survey and assigning them scores denoting the match level for a given candidate to a given workgroup (committee) in the AGH Students’ Council. this research is based on the Council’s recruitment applications that carried candidates’ responses to a set of 10 hypothetical Council member activity scenarios, where they were to choose one of four given solutions to the problems. the data was collected from a web quiz in 2020, validated on a voluntary insider control group’s responses to these questions and finally the best-performing model was evaluated in practice in the 2021’s recruitment inside an in-browser adventure minigame. this work provides insight into how models ranging from classical methods to deep learning perform in a very specific not yet well-explored in literature, practical non-linear problem that is dependent on individual features of the participants, withthe data volume being very limited due to a restricted population of candidates. this information may provide a starting point for applications of machine learning in decision support systems in recruitment processes.

this paper discusses the modelling and simulation of a reconfigurable wheelchair with a sit-to-stand facility for a disabled 25kg child. the prototype is designed in SolidWorks® and simulated in MATLAB® to get the suitable forces that have to be provided by the motors to activate the system. three different techniques will be used in modelling the wheelchair. SolidWorks® software package will be used in the initial stage in order to get an estimation of the necessary motor power. A second model of the system will be built using SimMechanics Matlab toolbox®. In order to check the results obtained from both approaches; SolidWorks and SimMechanics, the model built designed by SolidWorks is embedded in SimMechanics where the system has been simulated for the third time. In all the three simulation stages; the system is considered to do a complete cycle of motion; sit-to-stand and a stand-to-sit. the system performance has been detected based on an open loop scenario where no control is implemented as this stage. Further analysis of the system has been done considering the energy consumption in two different modes; sit-to-stand mode and a forward straight line motion for a prescribed distance.
