Conception of visual perception reveals the importance of binding intellection, apprehension and expression elements in the artistic training process. As the goal of upbringing is defined as the pursued reason and implicit result of activity, visual apprehension becomes an important tool in pursuit of not only implicit but also concrete results. Problem: Separation from concrete knowledge and their–conditioned practical activity distunes learners’ understanding of artistic activity and hinders development of common artistic sophistication, which in length of time slackens learners’ interest in arts and desire to continue learning. These issues are especially relevant in adolescence period (at the age of 12–14 years), when pupils get able to critically assess their drawings and are no longer satisfied with childish drawing schemes. Children of this age often come to the conclusion that they can’t draw, so they stop drawing at all. Research subject: influence of learning to draw spatial compositions upon visual apprehension of teenagers. Research goal: determination of influence of learning to draw spatial compositions upon visual apprehension of pupils of the 8th class. Hypothesis: Visual apprehension of teenagers will be nurtured more efficiently if training process involves drawing spatial compositions, based on practical application of skills developed. Tasks set before the study: 1) Overview of visual apprehension and visual expression issues as referenced in art... [to full text]

Magistro darbas, erdvinė kompozicija „Atminties kodas“ siekia paskatinti žiūrovą susimąstyti apie knygos kaip vieno reikšmingiausių žmonijos kultūrinio paveldo daugialypę prasmę. Žmonijos kultūrinė ir technikos raida įgauna vis didesnį pagreitį, naujų šiuolaikinių technologijų įtakoje, po truputi nyksta, tradiciniai grafiniai informacijos perteikimo būdai, užleisdami šią sritį virtualiosioms interneto platybėms. Sparti informacinių technologijų raida ir virtualėjanti bei vizualėjanti kompiuterinė realybė provokuoja svarstymus, ne tik apie knygos ateitį, bet ir apie knygos kaip meninio fenomeno likimą. Erdvinės kompozicijos „Atminties kodas“ kompozicinį centrą sudaro išdėstytos ratu knygos ant juodos kvadrato formos pakylos. Tai žmonijos intelekto raidą simbolizuojantis ratas, kurį supa pulsuojanti simbolių kreivė. Knygos istorinėje raidoje raštas palaipsniui keitėsi, kito ir jo laikmena - knyga. Piešinys oloje, virsta raide, papirusą keičia pergamentas, jį pakeičia popierius, popierių – skaitmeninė laikmena. Istorijos faktai pinasi, šokinėja tarsi sinusoidės kreivė šiuolaikiniame ekrane. / Master’s thesis spatial composition ” Memory code” aims to encourage the viewer think about the book’s as one of the most significant cultural heritage of mankind multiple meaning. Human cultural and technological development becomes more and more momentum for new modern technologies influence, gradually disappearing traditional graphical rendering techniques favor of this vast area of virtual web. The rapid development of information technology and computer reality provokes reflection not only about the future of the book but also about the book as a phenomenon of artistic destiny. Spatial composition “Memory code” is laid down in the centre of a circle of black paper on the square podium. This is a symbol of human intellectual development circle surrounded by pulsating character curve. In the historical evolution of the book its pattern gradually changed into another and also changed its medium- book. Design, written on the rock, turns into a letter, replacing papyrus parchment, it changes the paper and the paper changes the digital media. Historical facts mix and jump like a modern sinusoid curve on the modern screen.

Additive manufacturing (AM) – and laser powder bed fusion (LPBF) specifically – constructs geometry that would not be possible using standard manufacturing techniques. This geometric versatility allows integration of multiple components into a single part. While this practice can reduce weight and part count, there are also serious drawbacks. One is that the LPBF process can only build parts with a single material. This limitation generally results in over-designing some areas of the part to compensate for the compromise in material choice. Over-designing can lead to decreased functional efficiency, increased weight, etc. in LPBF parts. Methods to control the material composition spatially throughout a build would allow designers to experience the full benefits of functionality integration. Spatial composition control has been performed successfully in other AM processes – like directed energy deposition and material jetting – however, these processes are limited compared to LPBF in terms of material properties and can have inferior spatial resolution. This capability applied to the LPBF process would extend manufacturing abilities beyond what any of these AM processes can currently produce. A novel concept for spatial composition control – currently under development at Brigham Young University – utilizes liquid or liquid-encased dopants to selectively alter the composition of the powder bed, which is then fused with the substrate to form a solid part. This work is focused on evaluating the feasibility and usefulness of this novel composition control process. To do this, the present work evaluates two deposition methods that could be used; explores and maps the laser parameter process space for zirconia-doped SS 316L; and investigates the incorporation of zirconia dopant into SS 316L melt pools. In evaluating deposition methods, inkjet printing is recommended to be implemented as it performs better than direct write material extrusion in every assessed category. For the process space, the range of input parameters over which balling occurred expanded dramatically with the addition of zirconia dopant and shifted with changes in dopant input quantities. This suggests the need for composition-dependent adjustments to processing parameters in order to obtain desired properties in fused parts. Substantial amounts of dopant material were confirmed to be incorporated into the laser-fused melt tracks. Individual inclusions of 100 $nm$ particles distributed throughout the melt pool in SEM images. Howewver, EDX data shows that the majority of the incorporated dopant material is located around the edges of the melt pools. Variations of dopant deposition, drying, and laser scanning parameters should be studied to improve the resulting dopant incorporation and dispersion in single-track line scans. Area scans and multi-layer builds should also be performed to evaluate their effect on dopant content and dispersion in the fused region.
