An important idea in knowledge representation is that of libraries of reusable knowledge components. The goal of this research is to apply this idea to action description languages. An action language may be used to specify the effects and preconditions of actions, and serves to describe “transition systems” -- directed graphs with the vertices representing the states of an action domain and the edges representing the transitions that are caused by performing actions (or by the passage of time). Many actions can be described as special cases of other actions. (For example, pushing, carrying, going can all be described as special cases of moving things around.) However, descriptions of action domains in existing action languages describe the effects of all actions from scratch, which leads to common aspects of different domains getting reinvented over and over. In this dissertation we first developed a method for defining actions in terms of other actions, in the action language C+, a language with a rich set of features for describing action domains. This provided a theoretical basis for developing a library of general-purpose action descriptions and influenced the design of the Modular Action Description (MAD) language [Lifschitz and Ren, 2006], the semantics of which is based on C+. We extended the original MAD language in several ways, both in the syntactic dimension and in the semantic dimension, and developed an implementation of this extended language. The extended semantics not only provides new features but also addresses some shortcomings of the original semantics, which were identified during the course of our research. The implemented system was used to develop a library of basic MAD modules, each describing a group of general commonsense facts related to actions. Several action domains from the knowledge representation literature were formalized using the library of basic action descriptions. The availability of the library led to the representations being much simpler than before and also enabled us to recognize structural similarities of seemingly quite different domains. / text

Didėjantis mūsų gyvenimo tempas, dažniausiai nepalieka laiko poilsiui, bendravimui su artimaisiais, laikas tampa deficitu. Visi priversti skubėti, todėl vis labiau populiaresni tampa dizaino sprendimai, padedantys taupyti brangų laiką, sudarantys galimybę produkto vartotojui pačiam tapti kūrėju formuojant aplinką. Tai paskatino sukurti universalų baldą, lengvai transformuojamą. Šis kūrinys tarnaus ne tik kaip baldas poilsiui, atsipalaidavimui, bet atliks ir žaidybiškumo funkciją, lavins loginį mastymą ir vaizduotę. Bakalauro darbo pavadinimas „ DOMINO“. Tai modulinis transformuojamas baldas, kuris susideda iš 17 dalių. Pagrindas – lagamino formos dėžė, kuri gali transformuotis į minkštasuolį, staliuką su 16 minkštų odinių pagalvėlių, tinkantį laisvalaikio praleidimui, poilsiui, arba tarnauti kaip žaidybinė priemonė. Šį modulinį baldą lengvai galima transformuoti į lagaminą, tai sudarys galimybę jį patogiai transportuoti, panaudoti išvykose, ar poilsiaujant. Šis baldas puikiai tiks tiek mažose tiek didesnėse erdvėse, ar gamtoje. Spalvins komplekto sprendimas juodojo šokolado ir dramblio kaulo spalvos oda, tokį sprendimą lėmė tai, kad šios spalvos tradiciškai naudojamos šiame žaidime, tarpusavyje dera, nėra reiklios, todėl lengvai įsikomponuoja į aplinką, yra raminančios. Šis baldas puikiai tiks ir paaugliams ir suaugusiems. / The increasing pace of our lives often leaves no time to relax and communicate with our family and friends and time becomes a deficit. Therefore we can see increasing popularity of  design solutions that help to save valuable time, allowing the user to become himself a product designer in shaping his own environment. This led to the creation of universal furniture which is easily transformed. This creation will serve not only as a piece of furniture for relaxation but will have fuctions of entertaintment and will develop his owner's logical thinking and imagination. The title of this Bachelor's work is "Domino". The object of this work is a transformed modular furniture, which consists of 17 parts. The base of this furniture is suitcase which could be transformed into an armchair and a table with 16 upholstered leather pads, suitable for leisure, relaxation, or serve as a playful tool. This modular furniture could be easily transformed back to the suitcase, this fuction will be convenient to transport it and use during travels. This piece of furniture will suit both for small and large spaces as well as outdoors. Decision for the colour of the furniture was taken in regard of colours traditionally used in the game. Furthermore colours match each other and has calming features, also such combination of the colours is not demanding, so it could be easily integrated to environment. This furniture will be good for both adults and juveniles.

Baigiamajame darbe nagrinėjami moduliniai poilsio baldai. Darbo pavadinimas – „Modulinių poilsio baldų projektas „Fleksi““. Darbo apimtį sudaro 5 planšetai, filmukas, vaizduojantis sukurtus trimačius baldus, ir aprašas. Bakalauro darbe pateikiamas modulinių poilsio baldų aprašas. Darbą sudaro 7 dalys. Darbo tikslas – paruošti modulinių baldų projektą. Darbo uždavinys – sukurti gražius bei originalius baldus, kuriuos vartotojas galėtų pritaikyti pagal savo poreikius, kuriuos būtų galima lengvai transformuoti ir kurie leistų patirti naujus pojūčius. Darbo eiga prasidėjo nuo prototipų analizės. Nagrinėti įvairūs baldai, ieškant idėjos baldui. Buvo kuriami įvairūs eskizai, iš kurių išsirinkti geriausi. Tuomet buvo kuriamos jų schemos bei tolesni brėžiniai. Galutiniame variante sukurti keturi moduliniai poilsio baldai. Tai – lentyna su sėdima dalimi, staliukas, kėdė ir pakabinama lentyna. Baldus lengva transportuoti ir surinkti. Naujumas: baldai leis patirti naujus pojūčius. Baldus bus galima pritaikyti pagal savo poreikius bei iš turimų modulių sukurti tokį baldą, kokio nori vartotojas – kėdę, staliuką ar lentyną. / The final paper analyses modular leisure furniture. Topic: Modular Leisure Furniture Project "Fleksi". Paper volume includes 5 project drawings, video showing the created 3D furniture and description. Bachelor’s paper presents modular leisure furniture description. The paper is made of 8 parts. Aim of the paper: to design a modular leisure furniture project. Task: to create nice and original furniture to be adapted to customer’s needs. Furniture should be easily transformed allowing experiencing new sensations. Course: the work started with prototype analysis. I analysed various furniture in order to find an idea. Then I created various sketches, selected the best ones, made their schemes and further drawings. Finally, four modular leisure furniture pieces were created: the shelf with a sitting place, small table, chair and suspended shelf. The furniture is easy to assemble and transport. Novelty: the furniture will allow experiencing new sensations. The furniture can be adapted to one’s individual needs.

It is known that the ring of invariants of any two-row group is Cohen-Macaulay. This result inspired the conjecture that the ring of invariants of any two-row group is a complete intersection. In this thesis, we study this conjecture in the case where the ground field is the prime field $\mathbb{F}_p$. We prove that all Abelian reflection two-row $p$-groups have complete intersection invariant rings. We show that all two-row groups with \textit{non-normal} Sylow $p$-subgroups have polynomial invariant rings. We also show that reflection two-row groups with \textit{normal} reflection Sylow $p$-subgroups have polynomial invariant rings. As an interesting application of a theorem of Nakajima about hypersurface invariant rings, we rework a classical result which says that the invariant rings of subgroups of $\text{SL}(2,\,p)$ are all hypersurfaces. In addition, we obtain a result that characterizes Nakajima $p$-groups in characteristic $p$, namely, if the invariant ring is generated by norms, then the group is a Nakajima $p$-group. / Thesis (Ph.D, Mathematics & Statistics) -- Queen's University, 2009-09-29 15:08:40.705
