1. High-density surface EMG + EEG recordings of isometric ankle dorsiflexion, imaginary movement and GO/NO-GO tasks (HybridNeuro project)Nina Murks, Matej Kramberger, Leon Kutoš, Aleš Holobar, Matjaž Divjak, Ciaran McGeady, Dario Farina, 2026, zaključena znanstvena zbirka raziskovalnih podatkov Opis: This dataset was prepared in the context of the HybridNeuro project (https://www.hybridneuro.feri.um.si/). It contains a collection of simultaneous EMG and EEG recordings from 20 healthy volunteers. The main purpose of data collection was to assess the sensitivity of corticomuscular coherence detection estimated by the proposed motor unit-based EEG filters and compare it to the classical EEG processing techniques.
Surface EMG was recorded from the tibialis anterior muscle during isometric ankle dorsiflexions using 13 x 5 electrode array with 8mm interelectrode distance (model GR08MM1305 from OT Bioelettronica, Torino, Italy).
EEG was recorded with a 64 channel EEG cap (model EEG-Cap64 from OT Bioelettronica, Torino, Italy).
Both EMG and EEG were recorded simultaneously using the same amplifier (model Quattrocento from OT Bioelettronica, Torino, Italy) at 16 bit resolution and 2048 Hz sampling frequency.
For each participant, 25 tasks were recorded with total length of approximately 37 minutes. Each task's data is stored in a separate file in Matlab format (.MAT). Total dataset size is 26.9 GB.

2. Implementacija kontrolerja MIDI z internetom stvari in platformo Arduino : diplomsko deloAljaž Verbančič, 2025, diplomsko delo Opis: V diplomskem delu je predstavljen razvoj kontrolerja MIDI, ki temelji na platformi Arduino. Končni izdelek nudi 36 tipk v matriki 6×6, osvetljenih z diodami LED, ki pošiljajo serijske signale MIDI. Tipični ukazi se izvedejo v manj kot 2 ms, kar je primerljivo z industrijskimi napravami, poraba statičnega pomnilnika pa pri 1,12 kB spada v varno območje pomnilniškega prostora platforme Arduino Nano. Ohišje je izdelano s 3D-tiskanjem, pri čemer so bili za posamezne strukturne in funkcionalne komponente izbrani ustrezni materiali in filamenti. Naprava združuje nizko ceno s funkcionalnostjo, primerljivo z namenskimi komercialnimi kontrolerji. Delo prinaša uporabne vpoglede za Arduino navdušence in glasbenike, ki jih zanima izdelava lastnih naprav MIDI.

3. Razvoj sistema za blaženje prečno-smernih aerodinamičnih efektov : magistrsko deloMarko Ranđelović, 2025, magistrsko delo Opis: Cilj magistrske naloge je bil razviti sistem, ki stabilizira prečno-smerne efekte na letalo. Rešitev je namenjena pilotom jadralnih letal, ki takšnega sistema nimajo vgrajenega v osnovne stabilizatorje letala. Najprej smo predstavili osnove teorije problema, s katerimi smo bralcu, ki se morda ne spozna na letalstvo, razložili področje magistrske naloge. Nadalje smo opisali specifikacije komponent, uporabljenih za razvoj sistema. Prav tako smo opisali uporabljeno programsko opremo. Na koncu smo sistem preizkusili ter opisali rezultate.

4. The efficiency of manual editing of high-density surface electromyogram decomposition depends on the recorded muscle and contraction level but less on the operator’s experienceNina Murks, Jakob Škarabot, Matej Kramberger, Matjaž Divjak, Gašper Sedej, Tamara Valenčič, Christopher D. Connelly, Haydn Thomason, Aleš Holobar, 2025, izvirni znanstveni članek Opis: We investigated the agreement and accuracy of manual editing of the high-density electromyogram (hdEMG) decomposition results by seven human operators with various experience levels. All operators edited the same automatically decomposed experimental hdEMG from the first dorsal interosseous (FDI), tibialis anterior (TA), vastus lateralis (VL), and biceps brachii (BB) muscles, and synthetic hdEMG from soleus (SO) and BB muscles at 10%, 30%, 50% and 70% of maximum voluntary contraction. On average, operators kept 13.7 ± 7.4 motor units (MUs) after editing and demonstrated relatively large disagreement in the calculated MU pulse trains (normalized root mean square difference) but relatively high agreement in the identified MU discharges. Inter-operator agreement positively correlated with the initial MU Pulse-to-Noise Ratio used as a quality measure of automatic MU identification, and negatively correlated with the muscle contraction level. Operators agreed more on the results of the simulated than experimental hdEMG. Among the experimental muscles tested, the greatest agreement was demonstrated for VL and the lowest for BB. We obtained similar results when comparing editing to the results of the most experienced operator and to ground truth in simulated cases: the greatest precision and sensitivity were demonstrated for VL, and the lowest for BB. The level of the operator’s experience had a significant impact on the editing of synthetic hdEMG and the detection of the first MU discharge, but not on the rate of agreement or editing time of experimental hdEMG.

6. The effects of spinal manipulation on motor unit behaviorLucien Robinault, Aleš Holobar, Sylvain Crémoux, Usman Rashid, Imran Khan Niazi, Kelly Holt, Jimmy Lauber, Heidi Haavik, 2021, izvirni znanstveni članek Opis: Over recent years, a growing body of research has highlighted the neural plastic effects of
spinal manipulation on the central nervous system. Recently, it has been shown that spinal manipulation improved outcomes, such as maximum voluntary force and limb joint position sense, reflecting
improved sensorimotor integration and processing. This study aimed to further evaluate how spinal
manipulation can alter neuromuscular activity. High density electromyography (HD sEMG) signals
from the tibialis anterior were recorded and decomposed in order to study motor unit changes in
14 subjects following spinal manipulation or a passive movement control session in a crossover study
design. Participants were asked to produce ankle dorsiflexion at two force levels, 5% and 10% of
maximum voluntary contraction (MVC), following two different patterns of force production (“ramp”
and “ramp and maintain”). A significant decrease in the conduction velocity (p = 0.01) was observed
during the “ramp and maintain” condition at 5% MVC after spinal manipulation. A decrease in
conduction velocity suggests that spinal manipulation alters motor unit recruitment patterns with an
increased recruitment of lower threshold, lower twitch torque motor units.

9. Implementacija sistema za reševanje Rubikove kocke s pomočjo robota : diplomsko deloNejc Firbas, 2025, diplomsko delo Opis: Namen diplomskega dela je bil razviti in narediti robota, ki sam reši rubikovo kocko sestavljeno iz 3×3×3 manjših kock. Le ta je sestavljen iz 6 servo motorčkov, plastičnega ohišja in mikrokrmilnika Raspberry Pi. Robot najprej, preko kamere, zajame sliko in izračuna kombinacijo barv na vseh kvadratih, nato s pomočjo algoritma, imlementiranega v programu, določi zaporedje premikov stranic in le te nato tudi izvede s šestimi servo motorčki. Trenutno vitrualno sliko kocke lahko vidimo v nadzorni plošči, dostopni na izbranem naslovu IP v lokalnem omrežju. Preko nadzorne plošče lahko tudi upravljamo s krmiljenjem algoritma.
