Waste reduction possibilities in a manufacturing process

In this paper the manufacturing process of a high load-bearing capacity gear is introduced. These gears are built into truck and bus transmission systems and are machined at a high level of accuracy. The process has particular importance not only because the accuracy has to be ensured but because the machining of precision components requires relatively complicated processes. Here the process was described and quantified for a given component. The focus was on one-piece flow of components and its effect on decreasing lead time. On the basis of the analysis it was shown that one-piece flow can significantly decrease the lead time but the time spent with material handling increases, which results in a load on the operator or the material handling equipment. Therefore, multi-variable optimization is needed. The available results can be used for improvement of manufacturing processes of other component groups manufactured by similar technology

Characterizing sedimentary processes in abandoned channel using compositional data analysis and wavelet transform

Grain size distribution (GSD) is essential for characterizing the deposition process. However, it is necessary to consider its compositional constraint to comprehend the statistical distribution of size fractions within the sediments. Compositional data analysis (CoDA) and wavelet transform (WT) represent alternative methods beyond traditional approaches, e.g., probability density function (PDF). This paper introduces a quantitative approach for characterizing Quaternary depositional and environmental changes using abandoned channel infill sediments. The proposed approach integrates CoDA and WT to thoroughly comprehend the depositional patterns observed in abandoned channels and the underlying environmental variability. The depositional model constructed based on CoDA showed coarsening-upward sequences, suggesting a periodic connection between the main channel and the oxbow lake. Three scales of cycles consistent with the depositional model constructed using CoDA were identified based on WT: small, medium, and large-scale cycles of processes. The large-scale cycles indicate the main depositional events, while the medium and small scale reflects the variation within and during deposition. CoDA and WT demonstrate excellent potential in characterizing the GSD and interpreting oxbow lakes' deposition and sedimentation processes

MUSIC IN THE PSALM SUPERSCRIPTIONS

In this paper we study the superscriptions of the Psalms, especially those indications of genre and music that are phonetically transcribed in the Bible translations. Following the introduction, the study is divided into 3 sections. The first section provides some important information on the cult and musical role of the superscriptions: how they were created, what is their role, and why some Psalms have superscriptions, while others don’t. The second part etymologically and semantically explores those superscriptions, which, apart from genre, also indicate the way of musical performance, the instrumental accompaniment and the role of music next to singing, in general. A total of seven Hebrew concepts are explored concerning their meaning and etymology. The third part deals with superscriptions indicating musical performance and melody. Before going into a detailed analysis of each concept, however, the meaning of the term LAMÖNACÉAKH is presented. This concept is included in the superscription of 55 Psalms and is translated by Károli with the term “the director of music” each time. This is followed by an analysis of 10 concepts that are specifically related to the melody material, i.e. music. In which tone and accompanied by which instruments should the Psalm be performed, and to the melody of which other song should each be sung. The study concludes by discussing the etymology of the musical term SZELÁH. This musical symbol is not found in the superscriptions, but in the main text of the Psalms
