Grâce à leurs remarquables qualités de transport de charges et d’auto-organisation, les cristaux liquides colonnaires formés de molécules discotiques dérivées de colorants aromatiques sont des candidats prometteurs pour la réalisation de dispositifs photovoltaïques. Pour profiter à bien de ces propriétés, il est indispensable de maîtriser leur organisation en films minces. Un ancrage homéotrope avec les colonnes perpendiculaires au substrat est ainsi nécessaire pour conduire efficacement les charges aux électrodes. Cet alignement a été obtenu par transition d’ancrage entre un substrat solide et une cathode d’argent permettant d’obtenir des films ultra-minces (environ 25 nm d’épaisseur) homogènes orientés. Par ailleurs, une bicouche de composés discotiques intégralement alignée en ancrage homéotrope a été élaborée. A notre connaissance, ce travail constitue la première preuve de faisabilité d’une hétérojonction donneur – accepteur orientée constituée de cristaux liquides colonnaires. / Columnar liquid crystals made of discotic molecules derived from aromatic dyes are promising materials for the realization of photovoltaic devices thanks to their high charge mobility and their capacity to self-organize. In order to benefit from their anisotropic properties, it is necessary to control their organization in thin films. For example, a homeotropic anchoring where the columns are perpendicular to the substrate is required to carry the charges efficiently to the electrodes. Homogeneous homeotropically oriented ultra-thin films (approximately 25 nm) have been obtained by an anchoring transition between a solid substrate and a silver cathode. Moreover, a homeotropically oriented bilayer formed by discotic compounds has been achieved. This represents the first proof of principle of an organic heterojunction based on two oriented columnar liquid crystal layers.

Les systèmes d’ancrages adhésifs sont utilisés dans plusieurs applications en génie civil, notamment en réhabilitation et réparation des ouvrages d’infrastructure tels que des dalles de ponts, chaussées, tunnels, barrages, murs, poteaux, ainsi que dans certains travaux d’exploration géologique et minière. Un système d’ancrage adhésif comprend trois composants : l’élément d’ancrage : une barre d’armature ou une tige filetée ; le matériau adhésif : polymérique, cimentaire ou hybride ; et le substrat : en béton ou en maçonnerie. Les charges imposées sur les barres d’ancrage sont transmises au substrat par adhérence chimique (réactions) et liaison mécanique (interlock) entre les composants mentionnés. Le modèle de design d’adhérence uniforme établit que la performance structurale d’un système d’ancrage adhésif est déterminée par la contrainte de l’adhérence (τ), développée sur toute la surface de contact, entre les composants à l’intérieur du trou d’ancrage. Ce projet, en partenariat avec l’entreprise AMBEX, étudie et évalue la performance des systèmes d’ancrage avec adhésifs en matériau cimentaire, par rapport au comportement sous chargement continu. Pour ce faire, on a ancré des barres d’armature dans un substrat en béton conventionnel. Les deux adhésifs étudiés sont les cartouches d’ancrage AAC et ARC. On a tenu compte des paramètres géométriques et d’installation en assurant la rupture de l’adhérence lors des essais d’arrachement. On a évalué deux conditions en service: température ambiante (21ºC) et élevée (43ºC). On a effectué des essais statiques de traction et des essais sous chargement soutenu. Les résultats sont présentés dans des graphiques « chargedéplacement-temps », afin d’établir des prédictions futures de comportement. Le projet montre les avantages des ancrages adhésifs en matériau cimentaire, tels que le taux de fluage très faible sous chargement soutenu, et quelques limitations aussi, comme la variabilité des résultats à l’arrachement pour les ancrages avec la cartouche AAC. / Abstract : Adhesive anchoring systems are used in many civil engineering applications, including rehabilitation and repair of infrastructure such as bridge decks, roadways, tunnels, dams, walls, columns, and in some geological explorations and mining. An adhesive anchoring system consists of three components: the anchor: a reinforcing bar or a threaded rod; the adhesive material: polymeric, cementitious or hybrid; and a substrate of concrete or masonry. The loads applied on the anchor rods are transmitted by a chemical adhesion to the substrate (reactions) and mechanical interlock between the components mentioned. The design pattern of uniform adhesion establishes that the structural performance of an adhesive anchoring system is determined by the bond strength (τ) developed across the contact surface, between the components within the anchor hole. This project, in partnership with AMBEX, investigates and assesses the performance of an anchoring system, with an adhesive of cementitious material, related to the creep behaviour. To achieve this, steel rebars were anchored in a conventional concrete substrate. Two adhesives were evaluated: AAC and ARC cartridges. Geometrical and installation parameters were taken into account, to ensure bond failure during pullout tests. Two service conditions were studied: room temperature (21ºC) and high temperature (43ºC). Static tensile tests and creep tests were performed. The results are presented in graphs “load-displacement-time”, in order to make predictions of future behavior. The project shows the advantages of adhesive anchors made of cementitious material, as a feeble creep rate at sustained load, and also some limitations, as the variability of tension test results for anchors tested with AAC cartridge.

Introduktion: Psykisk ohälsa hos elever är ett växande problem. Svenska skolan ska arbeta med elevers trygghet och att bedriva ett systematiskt kvalitetsarbete mot diskriminering och kränkande behandling. Syfte: Syftet var att undersöka om pedagoger och elevhälsopersonal på en grundskola i en skånsk kommun upplever att trygghetsinsatserna har en positiv effekt på elevernas hälsa. Metod: En tvärsnittsstudie med kvalitativa inslag genomfördes av pedagoger (n=65) på en grundskola i Skåne. Datainsamlingen skedde genom digital enkät som skickades ut via e-post. Insamlad data analyserades i statistikprogrammet SPSS. Kvalitativa svar redovisades i textform. Resultat: Svarsfrekvensen var 34%, en för låg svarsfrekvens för att kunna generalisera resultatet.  Av respondenterna kände 73% sig delaktiga i trygghetsarbetet, 91% upplever att trygghet har effekt på elevernas hälsa och 67% uppfattar inga hälsoskillnader mellan kön. Däremot ses några skillnader i vilka insatser som fungerar bäst och sämst i relation till kön. Elevinsatser som involverar socialt utbyte upplevs mest positivt och bestraffningar mest negativt. Det efterfrågas systematik i trygghetsarbetet. Slutsats: Resultatet kopplas till tidigare forskning som både bekräftar och visar på förbättringsområden. Trygghetsplanens förekomst är grundläggande. Efterlyst tydlighet och uppföljning kan vara ett uttryck för områdets storlek och svårigheten att få en helhetsbild av trygghetsarbetet. Olika former av socialt utbyte är det som anses ha effekt på elevernas hälsa och bör därmed prioriteras. Trygghetsarbetet kan gagnas av kollegialt lärande och trygghetsplanens innehåll behövs eventuellt kompletteras. Framgångsfaktorer och förbättringsförslag kan bidra till en tydligare förankring. Den låga svarsfrekvensen ska dock tas i beaktande och eventuella genomföranden av förslag bör stämmas av med personal. / Introduction: Mental illness in students a growing problem. The Swedish school has the task of working with students' safety and to conduct systematic quality work against discrimination and offensive treatment. Purpose: The purpose was to investigate whether pedagogues and student health personnel at a primary school in a municipality in Skane felt that the safety efforts have a positive effect on the students' health. Method: A cross-sectional study with qualitative elements was conducted by educators (n = 65) at an elementary school in Skåne. The data collection was done through a digital survey that was sent out via e-mail. The collected data was analyzed in the statistics program SPSS. Qualitative answers were presented in text form. Result: The response rate was 34%, a too low response rate to be able to generalize the result. Of the respondents, 73% felt that they were participant in the safety work, 91% felt that safety had an effect on the students' health and 67% did not experience any health differences between the sexes. However, there are some differences in which efforts work best and worst in relation to gender. Student initiatives that involve social exchange are perceived to be most positive and punishment most negative. There is a demand for systematic security work. Conclusion: The result links to previous research that both confirms and demonstrates areas for improvement. The existence of the security plan is fundamental. Requested clarity and follow-up can be an expression of the area's size and the difficulty of obtaining a comprehensive picture of the safety work. Different forms of social exchange are what are considered to have an effect on the students' health and should therefore be given priority. Security work can benefit from collegial learning and the content of the safety plan may need to be supplemented. Success factors and improvement proposals can contribute to a clearer anchoring. However, the low response rate should be taken into account and any implementation of proposals should be reconciled with staff.

La réalisation et le maintien de la crédibilité de la politique monétaire, évaluée par l'écart entre les résultats et les annonces officielles de politique (Gilles [1992]), est devenue une tâche cruciale pour l'Autorité monétaire, lorsque, à partir des années 1980, il a été abordée, dans la littérature économique, la question du central banking (Gilles & Bastidon [2014], Ferguson et Schularick [2008]). Bien que les avantages de la crédibilité soient évidents, ses déterminants le sont moins. En effet, les dernières décennies sont marquées par de profondes mutations dans la gouvernance des Banques Centrales. En particulier, la délégation de la politique monétaire à une Banque Centrale indépendante vis-à-vis des pouvoirs publics est devenue un des principaux déterminants de la crédibilité dans les économies avancées (Goodfriend [2012]; Bordo & Orphanides [2013]; Persson & Tabellini, [1993]). Cependant, pour les Pays en développement, en revanche, le débat sur la nécessité et la faisabilité des mécanismes d'engagement n’est pas tranché, eu égards des caractéristiques spécifiques (Kugman & al [1992], Assoumou-Ella & Bastidon [2015]). En utilisant un modèle simple et une fonction de perte de la banque centrale similaire à celles de Ball [1999] ou Cavoli [2008], nous comparons deux régimes de change différents afin de déterminer lequel des cas est le plus susceptible d'inciter les gouvernements à intensifier la lutte contre la corruption, tout en maintenant l’objectif de stabilité des prix. Un régime d’ancrage crédible conduit à une taxation élevée et un faible niveau de corruption et d’inflation, mais également à un niveau de croissance faible. Un régime monétaire indépendant sans ancrage, en revanche, conduit généralement à un niveau de corruption plus élevée. Cependant, lorsque l’indépendance de la banque centrale est assez forte, le régime monétaire indépendant sans ancrage peut également conduire à moins de corruption, plus de production et de dépenses publiques, bien qu’avec une inflation plus élevée qu’un régime monétaire avec ancrage. Ces résultats semblent indiquer que dans le cas des Pays en développement, l’indépendance de la banque centrale associée à l’ancrage du taux de change ne serait ni une condition nécessaire, ni une condition suffisante à la stabilité des prix. / Achieving and maintaining the credibility of monetary policy, measured by the gap between outcomes and official announcements of policy (Gilles [1992]), has become a crucial task for the Monetary Authority when, from the 1980s, was tackled in the economic literature, the issue of central banking (Bastidon & Gilles [2014]). Indeed, the delegation of monetary policy to an independent central bank vis-à-vis the public authority has become a main determinant of credibility in advanced economies (Cukierman [1992], Bordo & Orphanides [2013]). However, its relevance for developing countries due to their specific characteristics (Kugman & al [1992], Assoumou-Ella & Bastidon [2015]) is far from being settled. Using a simple model and a loss of function of the central bank similar to those of Ball [1999] or Cavoli [2008], we compare two different exchange rate regimes to determine which cases are most likely to encourage governments to intensify the fight against corruption, while maintaining the objective of price stability. A credible anchor regime leads to high taxation and low levels of corruption and inflation, but at a low level of growth. An independent monetary regime unanchored, however, usually leads to a higher level of corruption. However, when the independence of the central bank is strong enough, the independent monetary regime unanchored can also lead to less corruption, more production and spending, although with higher inflation a monetary regime with anchor. These results suggest that in the case of developing countries, the independence of the central bank associated with pegged exchange rates would be neither a necessary nor a sufficient condition for price stability.

本文以優選理論為框架探討閩南語三字組及四字組重疊構詞，三字組及四字組重疊構詞可分成完全重疊與部分重疊，重疊詞要緊鄰其對應詞基越好，此外，對於四字組部分重疊構詞有對整方向不一致的體現，筆者認為不同的制約排序會產生不同的重疊規則，並採用音韻共存理論(Cophonology Theory)來解釋閩南語多元的重疊構詞策略是由多個次語法運作的結果。在三字組重疊構詞，根據句法結構判斷主重音的位置，主重音的分佈影響重疊的規則，但有語意強調某成份時，主重音會轉移且會使原成份之本調喪失變成輕聲，有主重音的音節才可進行重疊構詞，同時，重疊詞要越緊鄰其對應詞基。在四字組完全重疊構詞，語義的強調與弱化影響詞基音節以及音步的重疊運作，音節與音步制約層級不同可解釋不同的重疊規則；在四字組部分重疊構詞，不同於過去研究以單一方向對整制約論證，筆者提出雙向的對整制約來解釋四字組部分重疊構詞。簡言之，本篇論文藉由優選理論的觀點，首度就閩南語重疊構詞提出一個整體分析。 / This thesis examines the derivation of the reduplication in Taiwan Southern Min under the framework of Optimality Theory. Reduplication can be divided into two categories. One is trisyllabic reduplication and the other is quadrisyllabic reduplication. Besides, each type of the trisyllabic and quadrisyllabic reduplication has both partial and full reduplication. This thesis adopts Cophonology Theory to account for the subgrammar of the divergent reduplications. Based on Locality Generalization, the reduplicant should be adjacent to its corresponding base. In trisyllabic reduplication, from the perspective of syntactic relation, stress affects the derivation of the reduplication. The primary stressed syllable is the only syllable which can be reduplicated. This thesis proposes constraint *RED(W) to require this condition. In quadrisyllabic reduplication, given the base is disyllable AB, semantic weakness and stress closely relate to the full reduplication AABB and ABAB. The different ranking of the Adjacency-BR-by-syllable and Adjacency-BR-by-foot explains the full reduplication. In quadrisyllabic partial reduplication, this thesis proposes the different edges alignment constraint Align(RED, R; Rightmost Monosyllabic Morpheme, L) and Align(RED, L; Leftmost Monosyllabic Morpheme, R) to explain ABAC and ACBC, respectively. In summary, based on the constraint-based theory, and the interaction of Nonhead stress, Focal stress, *RED(W), alignment, anchoring, adjacency, and contiguity constraint, this thesis has given a general explanation of the reduplication in Taiwan Southern Min.

Dieser Beitrag befasst sich mit der experimentellen und analytischen Bestimmung der Verankerungslängen textiler Bewehrungsstrukturen einer Textilbetonverstärkungsschicht. Die experimentelle Untersuchung des Verbundverhaltens erfolgte anhand von Pull-Out-Versuchen. Die analytische Betrachtung des Verbundproblems geschieht aufbauend auf multilinearen Lösungen der Verbunddifferentialgleichung anhand der experimentell ermittelten Kraft- Rissöffnungs-Beziehungen. Mit Hilfe eines separaten Modells wird aus der so ermittelten Verbundspannungs-Schlupf-Beziehung (VSB) die zur Verankerung einer entsprechenden Kraft F erforderliche Verankerungslänge lE bestimmt. Die Überprüfung der Berechnung erfolgt anhand von unabhängig in experimentellen Versuchen zur Bestimmung der Verankerungslänge ermittelten Werten. Es konnte eine gute Übereinstimmung der berechneten mit den versuchstechnisch bestimmten Verankerungslängen festgestellt werden.

An der TU Dresden wurde eine Forschungsarbeit zur experimentell-theoretischen Analyse des Tragverhaltens von Verankerungen durchgeführt, die hauptsächlich zur oberflächenparallelen Einleitung großer Schubkräfte in einen Betongrund ausgelegt sind. Diese Verankerungen ermöglichen die Übertragung einer großen Querkraftbe¬anspruchung mit geringer Exzentrizität zur Oberfläche, die mit einer Normalbean¬spruchung in Zug- oder Druckrichtung kombiniert werden kann. Die wesentlichen Grundelemente sind zumindest ein Schubdübel, ein Zuganker und eine Grundplatte, mehrere Schubdübel oder Anker können vorhanden sein. Der quaderförmige Schub¬dübel überträgt die Kraft in den Beton. Die angreifenden Lastmomente und das Moment aus der exzentrischen Einleitung der Schublast werden in ein vor und hinter dem Dübel wirkendes Kräftepaar zerlegt. Die Zugkomponente wird dem Zuganker in Form eines Kopfbolzendübels zugewiesen. Die Grundplatte verbindet die lastseitige Befestigungskonstruktion mit den lastübertragenden Bauteilen Schubdübel und Zug¬anker. Gleichzeitig kann die Grundplatte in den Beton eingelassen sein und überträgt dann ebenfalls Schublasten. Die Lastabtragung und das Verhalten der Einbauteile im Versuch wurden analysiert. Von besonderer Bedeutung ist hierbei die Last-Verschiebungslinie, die die Lastüber¬tragung charakterisiert. Ziel war es, ein Bemessungskonzept zur Dimensionierung der Schubdübel zu erarbeiten. Um die im Versuch erkennbare maßgebende Beein¬flussung der Lastübertragungskapazität durch den sich einstellenden Verformungs¬zustand eingehender untersuchen zu können, wurde der Versuch mit finiten Elemen¬ten abgebildet. So war es möglich, in einem ersten Schritt Lastübertragungskapazitä¬ten für unverformte Systeme zu ermitteln, die praktisch im Versuch nicht oder nur extrem aufwändig realisiert werden könnten. In einem zweiten Schritt kann dann der Einfluss der Verformung berücksichtigt werden. Hierbei können die Parameter ge¬nauer und vielschichtiger variiert werden als dies bei den relativ aufwändigen Versu¬chen rein quantitativ möglich war. Das in dieser Arbeit vorgestellte Berechnungsver¬fahren liefert neben der maximal aufnehmbaren Schubbeanspruchung geometrisch beliebiger Einbauteile auch die Beanspruchbarkeit einzelner Baugruppen und erlaubt es zu beurteilen, inwieweit die einzelnen Lastübertragungsmechanismen additiv oder alternativ wirksam sind. Das Verfahren gibt Auskunft über das zu erwartende lastabhängige Verhalten der Einbauteile inklusive der Vorhersage von Teilversagens¬zuständen. Das Potential der Befestigungssysteme zur Übertragung großer Schublasten ist durch die Aufsplittung der Lastkomponenten und Übertragung durch spezialisierte Bauteile begründet. Diese können in ihrer Beschaffenheit den Erfordernissen optimal angepasst werden. Einsatzgebiete für diese Befestigungen sind alle konzentrierten Lasteinleitungen oder Montagestöße zwischen Betonbauteilen oder Stahl-Holz-Kon¬struktionen auf der einen und Betonelementen auf der anderen Seite. Neben der Auflagerung von Trägern oder Fassadenelementen ist vor allem auch an die Ertüchti¬gung und Verstärkung bestehender Betonbauteile durch zusätzliche Stahlkonstrukti¬onen zu denken. / An experimental and theoretical analysis of the behaviour of complex shear loaded fastenings was carried out at Dresden University of Technology. The main focus was on applications which introduce a great amount of shear load value parallel to the surface into a concrete base using a stell shear lug. The behaviour of these special fixings is presented as the result of the finished research program. Structures, as shown in the opposite figure, are able to transmit high values of shear loads to the anchor ground. An additional loading of normal force und bending moment is suitable, but will only be supposed to cover the necessary tolerance and off centre condition of the fixture parts. The advantage of fastening with shear lugs is based on the splitting of the load transfer into different components. The shear lug/lugs caries/carry the shear load, and the tie bar itself only balances the system by tension load due to moment loading and normal loading. Thusall loads are transferred by highly specialized components. If the base plate is embedded, there will be a shear load transferred in front of the base plate, too. The load carrying behaviour of the fastenings in the experiments is analyzed. Here, the load-displacement relationship is of special importance . This thesis aims at elaborating a dimensioning concept for the design of shear lugs. The tests show a decisive influence of the movements – displacements as well as rotations – of the fastenings to the load carrying capacity. In order to to be able to examine this behaviour, the experiment is redesigned by finite elements. In a first step it is therefore possible to examine fastenings without movements based on the anchor bolt stiffness. In a second step, the influence of the deformation can be explored. Here, the parameters can be varied more exactly and in a more complex way than this is possible in terms of quantity with the comparetively extensive test setup. The calculation method being introduced here does not only supply the maximum shear load transfer capacity of the hole fastening system, a system with free geometries, but also shows the partial shear load transfer capacity of the individual parts of the unit. This method is a means of predicting the load-related behaviour of the fastenings to be expected, including the forecast of partial failure states. As a result, a suggestion for the design of the fittings is shown. This design can be applied to all fittings by splitting the different load components to especially provided anchor elements. The design resistance and behaviour of the fastenings is estimated, depending on different geometries and stiffness conditions of the lug. Different strength classes of the concrete as well as different load combinations are taken into consideration. First examples from building sites are also available.

由於以往在願付價格的研究中，並未考慮到價格再高都願意支付的受訪者，以及價格再低都不願意支付的受訪者，因此可能會造成估計結果的偏差。本文除了沿用Tsai(2005)所建議採用的三要素混合模型，將受訪者區成價格再高都會願意付的人、願意付合理價格的人以及價格再低都不願意付的人等三類受訪者，且將願意付合理價格者的願付價格透過加速失敗模型(accelerated failure time model，簡稱AFT model)來作評估外，進一步就願意付合理價格的人可能會受到起價點的影響或是有「定錨效果」(anchoring effect)產生的問題來作探討，並就CVDFACTS的高血壓之願付價格資料來作實證分析。結果發現教育程度越高、收入越高以及男性對於能降低罹患心臟血管相關疾病新藥的願付價格也越高。此外我們也發現此筆資料確實有起價點偏誤(starting point bias)的情形。 / In the past, studies on willing-to-pay (WTP) usually assume that all the respondents are willing to pay a reasonable price for a non-market good. In reality, some of the respondents might be willing to pay a very high price, while some others unwilling to pay anything. Following Tsai(2005), we adopt a three-component mixture model to take into account these there three types of respondents and modeling those who are willing to pay a reasonable price with an accelerated failure time (AFT) model. In addition, with a slight modification, we also incorporate issues regarding “starting point bias” and “anchoring effect” into the model. An empirical study based on the data collected from “CVDFACTS” shows that males, respondents with higher educational level, and those with higher family income are willing to pay higher prices for a new hypertension treatment. In addition, it is quite likely that “starting point bias” exists in the dataset.

I rapporten har vi skrivit om naturstenens roll och förutsättningar som fasadmaterial inom byggproduktion. Målet med undersökningen var att belysa nya tekniker som finns på marknaden. Metoder som har använts för att undersöka infästningstekniker är genom intervjuer och studiebesök.   Den stora frågan var att ta reda på hur dem nya teknikerna kan påverka vår arbetsmiljö, miljö samt estetik. En annan fråga var hur den nya tekniken kan uppfylla de nya kraven?   Natursten är ett naturligt material som är inhomogen och därför förekommer det färgskiftningar och variationer i stenskivorna. En beställare ska därför vara väldigt specifik när stenen utses.   Det finns en stor risk med att förankra stenskivor utan mekanisk förankring. Utan förankringen kan stenen lossna från fasaden. Idag bygger vi vanligen med tekniken ventilerad luftspalt, mellanrum mellan stenskivor och stomme. På det sättet kan alla stenskivor röra sig utan spänningar samtidigt som luftspalten ventilerar och dränerar ut fukten bakom stenskivorna. Genom att välja lämpliga stendimensioner och ankare i standardutförande kan kostnaderna minskas. Denna rapport tar upp ny teknik. FZP, Fischer Zykon Panel, är ett undercut ankare. Detta är en valmöjlighet om en beställare vill erhålla skivor som är 20 mm i tjocklek.   Björn Shouenborg har designat ett program som gör det möjligt att dimensionera sten på fasader. Programmmet visar om dimensioneringen är ok med hänsyn till säkerhetskraven.   Med tanke på de stora miljökraven som ställs är det både lönande att undersöka möjligheter och ny teknik. Stommen byggs med mer isolering vilket kräver en längre expanderbult eller ankare mellan stenen och stommen.   I denna rapport framkommer det att en arkitekt och stenentreprenör är positiva till ACT-systemet.  Den här rapporten har belyst att den nya tekniken har en positiv påverkan på arbetsmiljön, miljön, estetik och tid. / The report talks about the capacity and conditions as a façade material within building construction. The goal with the research was to shed light on the new technique available today.  The methods used to examine the mechanical anchoring techniques were through interview and fieldstudies. The main question was to find out how those new technologies can affect our health and safety, environment and aesthetics. Another question is how the new technology can meet the new requirements?   Natural stone is a natural material that is inhomogeneous and therefore there are color variations and variations in stone tiles. A client should therefore be very specific when the stone is appointed. There is a great risk to anchor stone tiles without mechanical anchoring, without it the stone can detach from the façade. The technology most commonly used in anchoring stone is using a ventilated air gap, a space between the stone tiles and facade. In this way, all stone tiles move without tension and furthermore the air gap ventilates and drains the moisture behind the stone tiles. It is possible to cut costs by choosing the appropriate stone dimensions and tiles in the standard execution. New technology opens up new possibilities. An alternative is FZP, Fischer Zykon Panel which is an undercut anchor. This could be used as an option if a client wishes to have 20 mm thick tiles. Bjorn Shouenborg, researcher, has designed a program that makes it possible to dimension stone facades.The software that shows if the design is ok with regard to safety requirements.   Given the large environmental requirements imposed today, it is conceivable both be worthwhile to explore the possibilities and new technologies. The façade is built with more insulation which requires a longer expansion of anchors.   In this report, it appears that an architect and stone contractor is positive for the ACT system. This report has highlighted that the new technology has a positive impact on the work environment, the environment, aesthetics and time.
