Design and Optimization of Wheels for Better Aerodynamics and Cooling of Brakes

In the world of automotive, lots of research has been done yet on overall vehicle. Researchers improved every single part of vehicle but wheel is one of the part that hasn’t changed much in automotive history. In case researchers got their desired results, they stopped working on wheel and most of the research has been done on grip of the tire. That’s why there is no innovative research done on wheels. And it is one the biggest part who contribute in vehicles performance and other aspects like comfort and ride quality. Most of the manufacturers never consider and work on aerodynamic part of wheel. So, Different aerodynamics concept vehicles have been studied in the report. The flow around wheels are manage and smoothen in proposed design also it is designed in such a way that air flowing around wheel can easily take inside through Rim design and throw on brake pads as well as on wheel hub for consistently cooling them. They key for success is to manage the flow and keep the wheel functional and attractive. In this paper new wheel is designed and compared with convectional wheel designs.

Project Management Maturity Models for Construction Firms

This paper aims to identify and analyze project management maturity models in order to identify those best suited to be adopted in construction firms. To do so, models from papers available in academic repositories were analyzed. To be successful, the construction business deeply depends on projects outcomes; thus, the implementation of project management maturity models is important for this sector. A maturity model is a valuable technique to assess project management capabilities within a single part of an organization or to assess an organization as a whole. Its main purpose is to provide a means to create a more organized and predictable way for organizations to achieve their goals, increasing their chances of success regarding the outputs, outcomes, and benefits. In this paper, documentary research was performed to identify available project management maturity models and togather information about their performance. The information gathered was used to find elements to be compared with the identified models. Reviewing the literature, 39 project management maturity models were identified. The authors selected two PMMMs that were well fitted to assess the project management capabilities in construction firms: OPM3 and MMGP Prado.

Structure and Properties of Ti/Ti64 Graded Material Manufactured by Laser Powder Bed Fusion

Multimaterial additive manufacturing is an attractive way of producing parts with improved functional properties by combining materials with different properties within a single part. Pure Ti provides a high ductility and an improved corrosion resistance, while the Ti64 alloy has a higher strength. The combination of these alloys within a single part using additive manufacturing can be used to produce advanced multimaterial components. This work explores the multimaterial Laser Powder Bed Fusion (L-PBF) of Ti/Ti64 graded material. The microstructure and mechanical properties of Ti/Ti64-graded samples fabricated by L-PBF with different geometries of the graded zones, as well as different effects of heat treatment and hot isostatic pressing on the microstructure of the bimetallic Ti/Ti64 samples, were investigated. The transition zone microstructure has a distinct character and does not undergo significant changes during heat treatment and hot isostatic pressing. The tensile tests of Ti/Ti64 samples showed that when the Ti64 zones were located along the sample, the ratio of cross-sections has a greater influence on the mechanical properties than their shape and location. The presented results of the investigation of the graded Ti/Ti64 samples allow tailoring properties for the possible applications of multimaterial parts.

Optical inline monitoring of the burnish surface in the punching process

Punching is a wide-spread production process, applied when massive amounts of the ever-same cheap parts are needed. The punching process is sensitive to a multitude of parameters. Unfortunately, the precise dependencies are often unknown. A prerequisite for optimal, reproducible and transparent process alignment is the knowledge of how exactly parameters influence the quality of a punching part, which in turn requires a quantitative description of the quality of a part. We developed an optical inline monitoring system, which consists of a combined imaging and triangulation sensor as well as subsequent image processing. We show that it is possible to capture images of the cutting surface for every part within production. We automatically derive quality parameters using the example of the burnish height from 2D images. In addition, the 3D parameters are calculated and verified from the triangulation images. As an application, we show that the status of tool wear can be inferred by monitoring the burnish height, with immediate consequences for predictive maintenance. Although limited by slow images processing in our prototype, we conclude that connecting machine and process parameters with quality metrics in real time for every single part enables data-driven process modelling and ultimately the implementation of intelligent punching machines.

The Heraldic Shield and the Woman’s Body in the Blasons Anatomiques du corps féminin (1543)

In the French Renaissance, the term ‘anatomical blason’ (blason anatomique) designated a highly descriptive love poem praising a single part of a woman’s body, while in heraldry, the noun ‘blason’ defined the ensemble of ornamental components constituting the shield. Just as the French verb blasonner meant to describe and to interpret the shield’s material and symbolic parts, so could this verb be used in amatory poetry to signify the act of lauding the details of the beloved’s anatomical parts. This study examines the structural analogies between heraldic shield and the anatomical blason, addressing how the technical terms defining the shield’s components such as partitions, points, charges, tinctures, and the achievement could be given analogous expressions in the anatomical love poetry.

Joermungandr bolti , an exceptionally preserved ‘microsaur’ from the Mazon Creek Lagerstätte reveals patterns of integumentary evolution in Recumbirostra

The Carboniferous Pennsylvanian-aged (309–307 Ma) Mazon Creek Lagerstätte produces some of the earliest fossils of major Palaeozoic tetrapod lineages. Recently, several new tetrapod specimens collected from Mazon Creek have come to light, including the earliest fossorially adapted recumbirostrans. Here, we describe a new long-bodied recumbirostran, Joermungandr bolti gen. et sp. nov., known from a single part and counterpart concretion bearing a virtually complete skeleton. Uniquely, Joermungandr preserves a full suite of dorsal, flank and ventral dermal scales, together with a series of thinned and reduced gastralia. Investigation of these scales using scanning electron microscopy reveals ultrastructural ridge and pit morphologies, revealing complexities comparable to the scale ultrastructure of extant snakes and fossorial reptiles, which have scales modified for body-based propulsion and shedding substrate. Our new taxon also represents an important early record of an elongate recumbirostran bauplan, wherein several features linked to fossoriality, including a characteristic recumbent snout, are present. We used parsimony phylogenetic methods to conduct phylogenetic analysis using the most recent recumbirostran-focused matrix. The analysis recovers Joermungandr within Recumbirostra with likely affinities to the sister clades Molgophidae and Brachystelechidae. Finally, we review integumentary patterns in Recumbirostra, noting reductions and losses of gastralia and osteoderms associated with body elongation and, thus, probably also associated with increased fossoriality.

Soltan Hajibeyov’s “Caravan” Symphonic Poem

The article considers some features of the symphonic poem “Caravan” by the outstanding Azerbaijani composer Sultan Hajibeyov, studied the style of the work, the principles of symphonic development, methods used in orchestration. In the symphonic poem “Caravan”, a connection with national origins is clearly manifested. The improvisational principle inherent in mugham, the organic combination of melodic developmental techniques with symphonic development, the use of variable and variational development, as well as the creative use of national frets – all this arises from national music. The article deals with some features of the symphonic poem “Caravan” by the outstanding Azerbaijani composer Soltan Hajibeyov as a program work, examines the style of the work, the principles of symphonic development, and the methods used in orchestration. The purpose of the research is to study a number of features of the composer’s individual creative style in S. Hajibeyov’s symphonic poem “Caravan”. The disclosure of programming in the work, the consistent provision of epic drama in the genre of a single-part symphonic sketch, the disclosure of the connection of this feature with the mugham genre are the main points of the research. The research is based on the disclosure of the Eastern nature image through its manifestation mainly in a calm lyrical aspect and at the same time in an internal movement. The research methodology is based on a comprehensive generalization of the research of Azerbaijani and Russian musicologists in the genre of symphonic sketch based on musical-analytical, theoretical and historical analysis. Scientific novelty of the research. For the first time in the framework of Azerbaijani music science, the figurative content and orchestral features of S. Hajibeyov’s symphonic poem “Caravan” were considered from the perspective of oriental art. At the same time, based on the analysis, certain comparisons were made with the symphonic poem “In the Steppes of Central Asia” by the Russian composer A. Borodin, and the “Caravan” composition was studied in details. Conclusions. The symphonic poem genre is important in Azerbaijani music, and many interesting examples have been created in this area. The emergence and development of the symphonic poem genre in Azerbaijani music was associated with the emergence of interest and need for samples of a single genre. Thus, in Azerbaijani music, the symphonic poem genre prevails among one-act works, and this genre originated even earlier than the genre of the national symphony. Even though the symphonic poem genre in Azerbaijani music continues the traditions of the Russian School of composition, it is based on national musical intonations. Thus, the rhythmic structure of works, artistic content, and textured form is determined by national characteristics. From this point of view, S. Hajibeyov’s “Caravan” symphonic poem is the most striking example of this genre in Azerbaijani music. At the same time, the unique orchestration, texture, and use of sound timbres of instruments opened a new page in the field of National Symphony music. In particular, the use of intonations of mugham, the Azerbaijani oral traditional musical genre, brought originality to this work.

Networking of Digital Twins in the Digital Factory for Single Part Manufacturing Simulation

Organizing manufacturing in dynamic networks instead of inflexible production lines is one of the key aspects of Industry 4.0. This should serve to realize automation and effectiveness to a higher degree than previously achievable. For this modernization, Cyber-Physical Systems should be utilized, where a Digital Twin mirrors the behavior of its Physical Twin and makes the data during manufacturing externally available via communication interfaces. This Digital Twin should be an instantiation of a Digital Master, which must meet the requirements for communication in dynamically changing value-added networks. The networking capability of objects requires semantic information. This information is associated with rules for decision making within a value-added network. This paper addresses the need for research on how to add networking capabilities during the development of Digital Masters. With these added capabilities, the communication between Digital Masters and Twins in terms of a single part manufacturing simulation should be verifiable in a Digital Factory. For this purpose, the concept of this paper aims to outline guidelines on how to add networking capabilities to the single part, machines and other resources needed during manufacturing.
