Scoliosis embodies the most frequent three dimensional spinal deformities in children. Only timely treatment during the growth of the spine may significantly reduce related health problems inflicted by the deformity on adults. The results obtained via conservative therapy are problematic, and a certain degree of curvature already requires surgical treatment that currently consists in repeated spinal surgeries posing a high risk of complications. The aim is to use a spine model for computer based simulation of changes in the stress on the spine during idiopathic and syndromic deformity correction via vertebral osteotomy. One of the goals of the work was resampling and registration of the CT and MR image sequences. CT volumes provided solid contrast. Due to the low quality of the MRI volumes image data CT were used as a reference for gaining properly segmented groups of vertebrae. The concern of this work is a development of an extension module for 3D Slicer platform. The core of the module is an implementation of a Support Vector Machines classifier, which is used for segmentation of the vertebra image data provided by the University Hospital Brno. The resampling and registration techniques has been optimized to process the MR and CT data of all imaging sequences. CT volumes provide solid contrast and were used as a reference for gaining properly segmented groups of vertebrae. The extension module scripted in Python language is freely accessible as a 3D Slicer tool and can be used in the future to process new datasets.

An Intelligent Transportation System (ITS) is a modern technology aiming to improve traffic management and modes of transport. The Long-Term Evolution (LTE) standard is a suitable protocol for wireless communication systems in new ITS applications due to its high speed capacity. In this paper, a novel H-shaped filtering Wilkinson Power Divider (WPD) is proposed using H-shaped resonators at LTE standard and frequency of 1.8 GHz. Firstly, a compact LPF with simple structure is designed at 2.2 GHz cut-off frequency. The proposed LPF has a wide stop band from 2.85 GHz up to 8.16 GHz with more than 20 dB attenuation level, while the stop band can be considered from 2.5 GHz up to 20 GHz with more than 10 dB attenuation level. The results show that the measured insertion loss is less than 0.5 dB, the input and output return losses are more than 16 dB and 22 dB, while the ports isolation is higher than 17 dB at the main frequency. The proposed divider can correctly work at a 480 MHz bandwidth, which is corresponding to more than 25% fractional bandwidth. Furthermore, the harmonic suppression up to the eleventh harmonic is achieved for the proposed divider. The obtained measured results proved the efficiency of the proposed component.

In the last few years, Colombian coffee production has decreased by different economic factors related to the increment of costs in manual selective harvest operations. Consequently, an interest has arisen for studying selective harvesting methods based on mechanical vibrations in seeking for an alternative technology. In this sense, it is mainly essential to understand the dynamic behavior of the coffee fruits at different ripening stages. In this study, an experiment was proposed to observe the vibration shapes of coffee fruits (Coffea arabica var. Castillo) in defined frequency intervals. The ripening stages were categorized by a strategy based on color measurements in the CIELab space. Four ripening stages were determined from color data taken of 84 fruits, which allowed the development of the dynamic experiments over classified fruits. The dynamic excitation was applied to the coffee fruits between 0–1000 Hz in which ripe fruits evidenced higher vibration amplitudes in specific frequency intervals. These motions cannot be visualized from a normal video-camera (60 Fps). Therefore, a high-speed camera (Chronos 1.4) was used to record these during harmonic excitation. Eulerian video magnification technique was applied to the video-based measurements to visualize the amplified vibration shapes. The magnified motions were contrasted with vibrometry measurements and a piezo sensor attached to the fruit pedicel. Results show that the ripe fruit can vibrate with higher amplitudes in comparison with the other ripening stages, this information could be used to harvest selectively only ripe fruits.
在过去几年中，由于人工选择性采收作业成本的增加，不同的经济因素导致哥伦比亚咖啡产量下降。因此，人们对基于机械振动的选择性收获方法的研究产生了兴趣，以寻求替代技术。从这个意义上说，了解咖啡果实在不同成熟阶段的动态行为是至关重要的。在本研究中，提出了一项实验，观察咖啡果实(Coffea arabica var. Castillo)在规定的频率间隔内的振动形状。根据CIELab空间的颜色测量策略对成熟阶段进行分类。从84种水果的颜色数据中确定了四个成熟阶段，从而可以对分类水果进行动态实验。对0 ~ 1000 Hz范围内的咖啡果实进行动态激励，成熟果实在特定频率区间内表现出较高的振动幅值。这些运动无法从普通摄像机(60 Fps)中可视化。因此，在谐波激励时，使用高速摄像机(Chronos 1.4)记录这些。欧拉视频放大技术应用于基于视频的测量，以显示放大后的振动形状。放大后的运动与振动测量和附着在果蒂上的压电传感器进行了对比。结果表明，与其他成熟期相比，成熟果实的振动幅度更高，这一信息可用于选择性地收获成熟果实。

This paper is dealing with the exact measurement and calculation of the equivalent thermal conduction coefficient between the winding and the slot. The main issue is how to describe and solve the thermal conduction coefficient on the handmade wired small machine with a low slot filling factor. There is a precise model of the machine created and valuated by the real measurement.

This paper shows experimental results for three different methods used for a voltage synchronization to the three-phase grid. Tested methods are: traditional phase locked loop using Clarke and Park transformation (SRF-PLL), dual second-order generalized integrator phase locked loop (DSOGI-PLL) and sliding discrete Fourier transformation (sDFT). Experiments are carried out using controlled laboratory three phase power supply and show robustness of the methods to the noise, voltage distortion and sensitivity to grid frequency fluctuations. Finally, strong and weak aspects of the methods are discussed.

This paper deals with a review of potential technical applications of piezoelectric polymer systems for Industry 4.0 applications. Polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Copolymers of PVDF with beta phase could be used in piezoelectric and triboelectric applications which are presented in this paper. PVDF is a candidate for harvesters and sensors that cannot be realized with piezoceramics or single crystals. Both technical applications for sensing and energy harvesting are presented in this paper. These technologies could be useful in mechanical engineering applications like a strain sensor, strain energy harvesting, vibration energy harvester, load sensing and triboelectric sensors/generators. The opportunity for future usage in Industry 4.0 devices is outlined and experimental results of individual systems are presented.

The main reason for using asynchronous cage generators in ship’s systems is their reliability, simplicity of connection to the grid network and the possibility to implement the system at different generator rotation speeds. In addition, cage generators running on a DC network can easily distribute and sum up the power of generators running in parallel.In this article a test was carried out on a cage induction generator with an active rectifier and a load. The machine is controlled in a closed system with field-oriented control. The mathematical description of the system has been implemented. A model of this system was designed in the Matlab-Simulink package. The simulation results confirmed the functionality of the system and its good dynamic quality.

Research on Liquefied Petroleum Gas (LPG) use for automotive application is stemmed from the lower cost of the fuel and also from its lower emission potential. This paper details the experimental implementation of LPG fuel onto a Peugeot four cylinder common rail diesel engine. This diesel engine was already electronically controlled with an in-house Engine Control Unit (ECU) already reported in earlier IEEE papers. The electronic and software implementation performed to achieve Dual Fuel operation is detailed, i.e. LPG addition in gaseous state in the inlet manifold in conjunction with Diesel Injection directly into the cylinder. The Diesel Injection is used as the ignition source and thus is required throughout the engine operation, i.e. from idle to full load. LPG addition was utilized from 20% load upwards. The experimental setup used the Diesel ECU already reported and made use of additional electronic circuitry and LabVIEW to control the low impedance LPG injectors. The additional electronic circuitry and LabVIEW control are therefore the main contribution presented in this paper.
