Intelligent conceptual mould layout design system (ICMLDS) : innovation report
Family Mould Cavity Runner Layout Design (FMCRLD) is the most demanding and
critical task in the early Conceptual Mould Layout Design (CMLD) phase.
Traditional experience-dependent manual FCMRLD workflow results in long design
lead time, non-optimum designs and costs of errors. However, no previous research,
existing commercial software packages or patented technologies can support
FMCRLD automation and optimisation. The nature of FMCRLD is non-repetitive
and generative. The complexity of FMCRLD optimisation involves solving a
complex two-level combinatorial layout design optimisation problem. This research
first developed the Intelligent Conceptual Mould Layout Design System (ICMLDS)
prototype based on the innovative nature-inspired evolutionary FCMRLD approach
for FMCRLD automation and optimisation using Genetic Algorithm (GA) and Shape
Grammar (SG). The ICMLDS prototype has been proven to be a powerful
intelligent design tool as well as an interactive design-training tool that can encourage
and accelerate mould designers’ design alternative exploration, exploitation and
optimisation for better design in less time. This previously unavailable capability
enables the supporting company not only to innovate the existing traditional mould
making business but also to explore new business opportunities in the high-value
low-volume market (such as telecommunication, consumer electronic and medical
devices) of high precision injection moulding parts. On the other hand, the
innovation of this research also provides a deeper insight into the art of evolutionary
design and expands research opportunities in the evolutionary design approach into a
wide variety of new application areas including hot runner layout design, ejector
layout design, cooling layout design and architectural space layout design
Opportunities open to foreign banks in the Republic of Korea.

Yuriy Hryvniak as a researcher of the biography of Ivan Puluj
Матеріал тез присвячено дослідженню сторінок біографії
Юрія Гривняка - автора монографії про Івана Пулюя, яку було
опубліковано 1971 року у Лондоні завдяки фінансовій підтримці Союзу
українців у Великій Британії. Автором було використано ряд фото та
архівних матеріалів, отриманих від О. Пулюя. На жаль, творчість і
життєвий шлях Ю. Гривняка є маловідомими в Україні, а доля зібраних
ним джерел потребує фахового дослідженняThese theses are devoted to the study of the pages of Yuriy
Hryvniak’s biography. He was the author of a monograph dedicated to the study
of the life and activities of the famous Ukrainian scientist and public figure Ivan
Puluj. The author used a number of photos and archival materials received from
O. Puluj. Unfortunately, the creativity and life path of Y. Hryvniak is little
known in Ukraine, and the fate of the sources collected by him requires
professional researc
Natural product syntheses
This thesis is concerned with synthetic approaches towards the indole alkaloid koumine and the sesquiterpene quadrone. An intramolecular Diels-Alder reaction is the key step in our synthetic approaches to koumine. Chapter one describes some aspects of indole alkaloids including a general background, biosynthesis of strychnos alkaloids as well as the discovery of koumine and its pharmacological action. Chapter two deals with three potential routes to koumine and the important intermediate rel-(1R,6R,10S)-N-methyl-1-allyl-3-aza-2-oxobicyclo[4.4.0]dec-7-ene-10-y1-methanol has been prepared by way of a Diels-Alder reaction of maleic anhydride and (E)-3,5-hexadienylamine with further functionalisation. Quadrone, a sesquiterpene with a novel tetra cyclic system as well as antitumour activity, has become a popular synthetic target since its discovery and the main theme of our approach is a carbene cyclisation to form and basic skeleton. Chapter three describes the discovery of quadrone, its biogenetic origin and some previous sytheses. Chapter four explores 2 routes to the bicyclic intermediate 4-t-butyl-dimethyl-silyloxy-6,6-dimethyl-2-(2-oxo-2-propyl)bicyclo[3.2.1]octan-8-one which has been synthesised via a Michael addition of 4,4-dimethyl-2-(2-methyl-2-propyl) cyclopentanone with acrolein and subsequent intramolecular aldol condensation. Attempted preparation of the required carbene precursor (from this intermediate) using either a Horner-Wittig reagent or several halomethyltriphenylphosphonium halides proved unsuccessful.
