The prototype was developed in three main stages, namely forward and inverse kinematics modeling of the robot, simulation modeling of the prototype in MATLABSOLIDWORKS integrated environment, and finally the hardware development of the robot using 3D printing techniques. The operational performance of the constructed robotic hardware was then analyzed and compared with that of the developed simulation model. The experimental results of the robot performance evaluations suggested that the robot prototype has good operational precision performance in which the resulting maximum error for forward kinematics task is only about 2.745% whereas the resulting maximum error for inverse kinematics task is only about 0.06%.

The alpine environment is characterized by complex geology, high-energy terrain, deeply incised river valleys with high erosional potential, extreme weather conditions and dynamic geomorphic processes. Such settings provide favourable conditions for the formation of composite landslides rather than individual slope mass movement phenomena. As an example, we present the kinematics of the composite landslide Urbas in the North of Slovenia which developed in the complex geological and morphological settings characteristic of the alpine environment. The research combines several monitoring techniques and involves the integration of both surface and subsurface displacements measured in the landslide area. The results indicate that the composite sliding process consists of several simultaneous and interrelated types of movements occurring in different segments of the unstable mass that are governed by different mechanisms of displacements, such as rockfall, sliding and debris flow. The kinematic characteristics of a deep-seated landslide that formed in such conditions vary spatially, but is rather homogenuous vertically, indicating translational type of movement. Spatial kinematic heterogeneity is primarily related to the diverse terrain topography, reflecting in different displacement trends. Based on the revealed kinematic proprieties of the sliding material, the sediment discharge illustrates the sliding material balance which estimates the volume of the retaining material that represents the potential for slope mass movement events of larger scales.

In the development of OMR, other capabilities can also be added, such as the ability to reach the desired position and avoid obstacles. In this paper, we will design and simulate OMR with three omni wheel configurations using the potential field method which can move to the desired point and avoid obstacles. The design begins with determining the kinematics of the OMR, then the potential field method is applied and the last is simulation in a two-dimensional view using MATLAB software and analysis. The results of the first simulation show that OMR can move in all directions without changing the orientation of the robot based on the kinematics that has been designed. The results of the second simulation of OMR successfully reach the desired point and can avoid two obstacles.

Abnormal feet progression angle, i.e. abnormal feet rotation during walking, is one of the pathologies which can be revealed by mere visual inspection. It is an epiphenomenon of a series of diseases, some of which are indicated for therapy by insoles. However, some of the small, but clinically significant changes caused by the insoles cannot be captured with the naked eye. Therefore, their actual effect may not always be interpreted properly. The aim of this study was to objectify the immediate effect of bars of sensorimotor insoles on the feet progression angle in the stance phase of the gait cycle in asymptomatic adults. The feet progression angle was assessed during walking with the base sole both with and without the individual bars of sensorimotor insoles, using the Vicon optoelectronic system in 11 subjects altogether (age 23,0 ± 3,3 years, height 174,4 ± 8,4 cm, weight 66,9 ± 6,0 kg). The results show that bars can significantly change the feet progression angle. During walking, retrocapital bars rotate feet outwards in relation to the base sole; calcaneal medial bars rotate feet inwards. [ABSTRACT FROM AUTHOR]

Progressivity of Basic Elements of the Slovenian National Alpine Ski School Ski school programmes in different countries are adapted to the local conditions and skiing trends. The aim of the study was to establish the progressivity of the three basic elements of the Slovenian ski school in terms of the duration of individual turns and their phases. Eight participants were recorded as they performed three basic elements of the Slovenian national ski school: wedge curves – E1, turns with a wedge push-off – E2 and basic swinging – E3. According to the ski school, the elements were divided into phases. The results of the computer-aided video analysis showed that in the beginning types of skiing in the same conditions on the same length of terrain, the average durations of turns and the times of comparable initiation and steering phases of the elements shortened on the methodical upward scale (from E1 to E3). The number of turns executed on the same length of terrain from E1 to E3 increased. A larger step in motor task complexity was indicated when a pole plant was included in skiing elements. Further, relatively large differences were observed in time durations among subjects executing the same elements. In conclusion, it can be assessed that the basic elements of the ski school are placed gradually in terms of progressivity in time durations. Progresivita základních elementů slovinské národní školy alpského lyžování Programy lyžařských škol v různých zemích jsou přizpůsobeny místním podmínkám a lyžařským trendům. Cílem této studie bylo stanovit progresivitu tří základních prvků slovinské lyžařské školy, pokud jde o dobu trvání jednotlivých zatočení a jejich fází. U osmi účastníků bylo zaznamenáno, jak provádějí tři základní prvky ze slovinské národní lyžařské školy: E1 – oblouk z pluhu; E2 – oblouk z přívratu vyšší lyží E3 – paralelní oblouk. Podle lyžařské školy byly prvky rozděleny do fází. Výsledky počítačové video- analýzy ukázaly, že na začátku lyžování za stejných podmínek a stejné délky terénu, je průměrná doba zatáčení a časů srovnatelného zahájení a řízení fází, jsou tyto prvky dle metodické vzestupné škály zkráceny (od E1 po E3). Počet zatočení provedených na stejné délce terénu se zvýšil; od E1 po E3. Delší pokrok byl v motorické komplexnosti úlohy, indikován při jejich začleněného do lyžařských prvků. Poměrně velké rozdíly mezi subjekty, které prováděli stejné prvky, byly zaznamenány v době jejich trvání. Na závěr lze usuzovat, že základní prvky lyžařské školy jsou postupně z hlediska progresivity podle času jejich trvání, implementovány.

Pembelajaran Jigsaw merupakan salah satu strategi pembelajaran yang kooperatif dan fleksibel. Dalam pembelajaran Jigsaw, siswa dibagi menjadi kelompok-kelompok yang anggotanya mempunyai karakteristik heterogen. Masing-masing siswa bertanggung jawab untuk mempelajari topik yang ditugaskan dan mengajarkan pada anggota kelompoknya, sehingga mereka dapat saling berinteraksi dan saling bantu. Kinematika merupakan cabang ilmu fisika yang mempelajari konsep dasar mekanika untuk memahami konsep-konsep fisika lebih lanjut. Terdapat tiga langkah yang harus dilakukan dalam mengatasi kesulitan siswa memahami kinematika, yaitu: (1) memperbaiki miskonsepsi pada konsep prasyarat siswa dengan model konstruktivisme, (2) menyelesaikan persoalan fisika dengan metode pembelajaran koperatif Jigsaw, (3) memaksimalkan kemampuan matematis siswa menyelesaikan persoalan kinematika dengan sistematis, dan memperbaiki bahasa matematika yang digunakan menjadi lebih sederhana. Langkah-langkah tersebut, dibagi lagi menjadi beberapa urutan tahapan yang harus dilakukan, mulai dari persiapan, pelaksanaan, hingga evaluasi.
