Abstract This analytical approach aims to demonstrate the connection between music and technology in the creation of composer Viorel Munteanu. The purpose of this paper is to identify and analyse the music cryptograms in Symphony No. 1 “Glossa” using digital analysis tools. Viorel Munteanu is a modern composer characterised by avangardist tendencies, but with a desire to revive the past. In his creations, the composer uses folkloric themes and byzantine chant, while evoking important personalities of Romanian culture. In Symphony No. 1 “Glossa”, Munteanu uses the music cryptogram of poet Mihai Eminescu and composer George Enescu, these structures being used as thematic material and cyclic motifs. For graphical illustration of the music cryptograms we used the digital library LibRosa and for the identification process we use a musical software which identifies these structures in a MIDI score. Also, we would be analysing the cryptograms’ functions, rhetorics and aspects influencing the form and genre of the symphony.

Abstract This paper describes the computer aided design system Modessa. Modessa is developed to support multi-disciplinary design teams in the conceptual design phase. Modessa is based on the “morphological design method” which decomposes the design problem into a number of so called functions. Then several alternatives are identified for each of these functions. These alternatives are visualized using pictures and arranged by function in a matrix which results in a so called “morphological overview”. Finally the alternatives are evaluated based on the customer requirements. The best alternatives for each function are combined to form the optimum solution for the design problem. Modessa supports multi-disciplinary design teams during the conceptual design process by: - Suggesting known design alternatives for design functions, thus leaving more time for the creation of novel design alternatives. - Offering a “common language” to objectively evaluate the design alternatives. - Simplifying the creation and reuse of the conceptual design documentation. Modessa is general purpose in nature and can be used for a wide variety of design applications. The kernel of Modessa is a design knowledge database that increases continuously as design teams add new functions (problems) and appropriate alternatives (solutions). In this paper the use of Modessa is illustrated by an industrial design example.

The Creation

Direct digital manufacturing (DDM) is the creation of a physical part directly from a computer-aided design (CAD) model with minimal process planning and is typically applied to additive manufacturing (AM) processes to fabricate complex geometry. AM is preferred for DDM because of its minimal user input requirements; as a result, users can focus on exploiting other advantages of AM, such as the creation of intricate mechanisms that require no assembly after fabrication. Such assembly free mechanisms can be created using DDM during a single build process. In contrast, subtractive manufacturing (SM) enables the creation of higher strength parts that do not suffer from the material anisotropy inherent in AM. However, process planning for SM is more difficult than it is for AM due to geometric constraints imposed by the machining process; thus, the application of SM to the fabrication of assembly free mechanisms is challenging. This research describes a voxel-based computer-aided manufacturing (CAM) system that enables direct digital subtractive manufacturing (DDSM) of an assembly free mechanism. Process planning for SM involves voxel-by-voxel removal of material in the same way that an AM process consists of layer-by-layer addition of material. The voxelized CAM system minimizes user input by automatically generating toolpaths based on an analysis of accessible material to remove for a certain clearance in the mechanism's assembled state. The DDSM process is validated and compared to AM using case studies of the manufacture of two assembly free ball-in-socket mechanisms.

Distributional Semantic Models

Measuring the semantic similarity and relatedness of words is important for many natural language processing tasks. Although distributional semantic models designed for this task have many different parameters, such as vector similarity measures, weighting schemes and dimensionality reduction techniques, there is no truly comprehensive study simultaneously evaluating these parameters while also analysing the differences in the findings for multiple languages. We would like to address this gap with our systematic study by searching for the best configuration in the creation and comparison of feature vectors in distributional semantic models for English, Spanish and Hungarian separately, and then comparing our findings across these languages. During our extensive analysis we test a large number of possible settings for all parameters, with more than a thousand novel variants in case of some of them. As a result of this we were able to find such configurations that significantly outperform conventional configurations and achieve state-of-the-art results.

In  order  to  synchronize  signals  at  receiving  points  in  high‑speed  digital  electronics,  the  configurations  of  the  corresponding  tracks on the PCB must ensure the same signal delays. Their synchronization is ensured by the creation of topological delay  lines, which are realized by inscribing a meander in a certain area, as a rule, a rectangle. The article analyzes the influence of  the parameters of the delay line and the shape of the inscribed conductor on the efficiency of use of the installation space. It is  noted that computer‑aided design systems offer two basic options for inscribing a meander in a rectangular area: «accordion»  and «trombone». The impossibility of reducing and the inexpediency of increasing the width of the region of the delay line in the  «trombone» variant makes its use in narrow or short «corridors» ineffective. Therefore, the «accordion» version is considered  more versatile and flexible. It also concludes that it is preferable to use long narrow areas of delay lines and the advisability to  avoid very short and too narrow areas when automatically creating topological delay lines.

In order to create a Computer Aided Process Planning (CAPP) model for a family of parts, it is necessary to establish a database containing the geometric features specific to that family. In the car body production line industry, several families of parts can be determined each having specific geometric features. The parts that are part of a family of parts must be designed in such a way that at the end, they contain those specific features. The next step in the implementation of the CAPP model, is to create a database for processing sequences associated with geometric features. Combining these two databases, the database of geometric features and the processing sequences, the result is the NC program of the designed part. This study presents the creation of these two databases and the link between them.
