Full textMålet med projektet är att konstruera en lågvikts robotmyra som kan uthärda stora krafter och härma myrors rörelse vid lyft så mycket som möjligt. Projektidén valdes med inspiration från naturen, speciellt från de otroliga krafter hos en myra. Myror har bevisats kunna lyfta och bära tunga laster eller mer exakt tusen gånger sin egen vikt. Olika lyfttekniker används av flera faciliteter idag och därmed finns det behov av förbättringar i detta område. Genom att efterlikna en myras utseende och härma dess rörelser designades en sexfoting under en period på fyra månader. Testerna delades in i tre olika kategorier; stabilitet, lyft- och greppförmåga. Den bästa balansen uppnåddes då benens kontaktpunkter med marken placerades så långt ifrån varandra som möjligt. Totalt klarade robotmyran att lyfta 1.02 gånger sin egen vikt och bära 3.01 gånger egna vikten på ryggen.

Full textThe synthetic ecosystems approach attempts to adopt basic principles of natural ecosystems in the design of multiagent systems. Natural agent systems like insect colonies are fascinating in that they are robust, flexible, and adaptive. Made up of millions of very simple entities, these systems express a highly complex and coordinated global behavior. There are several branches in different sciences, for instance in biology, physics, economics, or in computer science, that focus on distributed systems of locally interacting entities. Their research yields a number of commonly observed characteristics. To supply engineered systems with similar characteristics this thesis proposes a set of principles that should be observed when designing synthetic ecosystems. Each principle is systematically stated and motivated, and its consequences for the manufacturing control domain are discussed. Stigmergy has shown its usefulness in the coordination of large crowds of agents in a synthetic ecosystem. Sign-based stigmergy through synthetic pheromones is supported by an extension to runtime environments for software agents called the pheromone infrastructure. In this thesis the operation of the pheromone infrastructure is specified, formally modeled and analyzed, and an implementation is presented. The guided manufacturing control system for flexible flow shops is designed following the proposed principles and it uses the pheromone infrastructure to coordinate its agents. It comprises two subsystems. The control (sub)system, which enables production, is distributed and reactive. The advisory (sub)system observes the operation of the control system and advises the manufacturing execution under global considerations. This thesis specifies the guided manufacturing control system and evaluates its operation in a simple but realistic example adapted from the automotive industry. The applicability of the design principles, the usage of the pheromone infrastructure, and the operation of manufacturing control in abstract state spaces are considered on the basis of the guided manufacturing control system.

Full textSUMMARY Painting on silk - is the art of close feelings. This technology emerged in China and has spread all over the world, but every nation understood the painting on silk and interpreted it in their own way. Paintings on silk are very popular and lovely occupation. Not only artists, but women, teachers and students are interested about painting on silk. This activity coordinates the activities of students, which stimulates curiosity, activity, stimulate thinking. So, my work theme is: Painting on silk “Poppy meadow”. I chose this motif of a plant, because poppy - a symbol of survival and fragility, which is less frequently encountered in Lithuanian ornamentation and this reason, further encouraged finding out precisely poppy motif paintings. Work aim: to analyze the poppy crop in history, mythology, symbolism, and folklore represented by painting on silk. Work tasks: To explore the history and symbolism of poppy plants; To analyze the significance of poppies ring in mythology and folklore; To explore the poppy negative and positive effects for human health; To review the history and techniques of painting on silk; To analyze the techniques of painting on silk adaptation in technology lessons; To do a creative work: “ Poppy meadow”. Work methods: Information Resource analysis; student achievement analysis in technology lessons, creative work. This work describes the performance of creative work. I decided to paint a poppy meadow. The composition of... [to full text]

Full text* A survey of metaheuristics. Chapter 1 gives an extensive overview on the nowadays most important metaheuristics. This overview points out the importance of two important concepts in metaheuristics: intensification and diversification.
* The hyper-cube framework. Chapter 2 introduces a new framework for implementing ACO algorithms. This framework brings two main benefits to ACO researchers. First, from the point of view of the theoretician: we prove that Ant System (the first ACO algorithm to be proposed in the literature) in the hyper-cube framework generates solutions whose expected quality monotonically increases with the number of algorithm iterations when applied to unconstrained problems. Second, from the point of view of the experimental researcher, we show through examples that the implementation of ACO algorithms in the hyper-cube framework increases their robustness and makes the handling of the pheromone values easier.
* Deception. In the first part of Chapter 3 we formally define the notions of first and second order deception in ant colony optimization. Hereby, first order deception corresponds to deception as defined in the field of evolutionary computation and is therefore a bias introduced by the problem (instance) to be solved. Second order deception is an ACO-specific phenomenon. It describes the observation that the quality of the solutions generated by ACO algorithms may decrease over time in certain settings. In the second part of Chapter 3 we propose different ways of avoiding second order deception.
* ACO for the KCT problem. In Chapter 4 we outline an ACO algorithm for the edge-weighted k-cardinality tree (KCT) problem. This algorithm is implemented in the hyper-cube framework and uses a pheromone model that was determined to be well-working in Chapter 3. Together with the evolutionary computation and the tabu search approaches that we develop in Chapter 4, this ACO algorithm belongs to the current state-of-the-art algorithms for the KCT problem.
* ACO for the GSS problem. Chapter 5 describes a new ACO algorithm for the group shop scheduling (GSS) problem, which is a general shop scheduling problem that includes among others the well-known job shop scheduling (JSS) and the open shop scheduling (OSS) problems. This ACO algorithm, which is implemented in the hyper-cube framework and which uses a new pheromone model that was experimentally tested in Chapter 3, is currently the best ACO algorithm for the JSS as well as the OSS problem. In particular when applied to OSS problem instances, this algorithm obtains excellent results, improving the best known solution for several OSS benchmark instances. A final contribution of this thesis is the development of a general method for the solution of combinatorial optimization problems which we refer to as Beam-ACO. This method is a hybrid between ACO and a tree search technique known as beam search. We show that Beam-ACO is currently a state-of-the-art method for the application to the existing open shop scheduling (OSS) problem instances.

Full textENGLISH ABSTRACT: Alien trees, Pinus spp. and Eucalyptus spp., affect ants negatively in the Cape Floristic Region (CFR), a global biodiversity hotspot in South Africa. They reduce ant abundance and species richness, thus also changing ant assemblage structure. This is alarming, because almost 1300 species of plant species in the CFR are dispersed by certain indigenous ants, and thus there is concern for an indirect effect on indigenous plant assemblages. One of the most impacting ant species on seed dispersal is the invasive Argentine ant (Linepithema humile (Mayr)), which discards seeds outside its nest, where they do not germinate. Ten sites, on Vergelegen Wine Estate, were selected to explore these effects of alien plants. These varied from invaded to non-invaded sites. Each site consisted of six sampling points, which in turn consisted of four pitfall traps left out for seven days, during December 2005, February 2006, May 2006 and September 2006. Forty species of ant were sampled, and various analyses used to illustrate the comparative effects of plant invasion. All analytical methods showed that invasive alien plants had a significant impact on the abundance and richness of the ant species assemblage, by creating a dense canopy cover that changed the abiotic environment of the epigaeic ants’ habitat. Furthermore, increased alien tree invasion correlated significantly with Argentine ant abundances. The Argentine ant displaced Pheidole capensis and Camponotus spp., while it decreased the abundances of commonly-occurring indigenous ants, such as Lepisiota capensis and Plagiolepis spp. Displacement by the Argentine ant may be a result of indirect competition for food resources. The effects of invasive aliens are synergistic in that there is a cascade effects from initial plant invasions to subsequent animal invasion.
AFRIKAANSE OPSOMMING: Indringer bome, Pinus en Eucalyptus, affekteer miere op negatiewe wyse in die Kaap Florsitiese Streek (KFR), ‘n area in Suid Afrika van belang t.o.v. globale biodiversiteit. Hierdie uitheemse indringer bome verminder hulle hoeveelheid en spesies rykheid. Die bogenoemde is kommerwekkend omdat meer as 1300 plant spesies in the KFR versprei word deur miere. Die verandering in hoeveelheid en versameling van inheemse miere kan dus ernstige implikasies hê op die saad verspreiding van inheemse plant spesies. Een van die mees verwoestende effekte op saad verspreiding is veroorsaak deur die indringer Argentynse mier (Linepithema humile (Mayr)), wat sade neer werp buite hulle neste, waar hulle nie suksesvol kan ontkiem nie. Tien monsterings-tereine was geselekteer om die bogenoemde effekte te ondersoek op Vergelegen Landgoed. Hierdie het afgewissel van indringer tot skoon tereine. Elke terrein is op ses versamelings-plekke gemonster, met vier pitvalle, wat oopgelê het vir sewe dae gedurende Desember 2005, Februarie 2006, Mei 2006 en September 2006. 40 spesies van miere was gemonster. Indringer plante het ‚n betekenisvolle impak gehad het op die hoeveelheid en rykheid van die mier gemeenskappe, deur die skepping van ‚n dig baldakyn wat die abiotiese omgewing van die miere se habitat verander het. Die vermeerdering van indringer plante veroorsaak die vermeerdering van Argentyne miere. Kanonieke Mede-Respons Analise illustreer dat die Argentynse mier Pheidole capensis en Camponotus spp. verplaas het, terwyl dit ander inheemse mier getalle verminder het, soos Lepisiota capensis en Plagiolepis spp. Die verplasing deur die Argentynse mier mag die resultaat wees van indirekte wedywering vir hulpbronne. Die effekte van indringer species is dus sinergisties deur dat ‚n kaskade effek ontstaan vanaf plant tot dier indringer spesies.
