This study aims to estimate the level of satisfaction about resettlement arrangements for local people who have been affected by A Luoi hydroelectric construction project in the Thua Thien Hue province. This research used the Likert scale method to assess the satisfaction level of 98 households living in two of the resettlement sites. Results illustrate that there is variations in the level of satisfaction of local people in the two resettlement sites, Hong Thuong and Hong Ha. In the resettlement area (RA) of the Hong Thuong Commune, people are dissatisfied with the location arrangement. There is a lack of quality in the houses built, been damaged, cracked and degraded, since the construction design is not appropriate for the customs and practices of local people, with a satisfaction rating of 1.07. Meanwhile, at the resettlement site of the Hong Ha commune, people felt satisfied with the arrangement site of the RA and allocated residential land area with the satisfaction rating of 4.19. Our results will help the government, as well as the project owners, to understand the points of dissatisfaction of local people in order to have accordant solutions, ensuring the stable life for local people in those settlement areas. / Nghiên cứu này nhằm mục đích đánh giá được mức độ hài lòng của người dân về việc bố trí tái định cư (TĐC) cho người dân bị ảnh hưởng bởi dự án xây dựng thuỷ điện A Lưới, tỉnh Thừa Thiên Huế. Nghiên cứu đã sử dụng phương pháp thang đo Likert để đánh giá mức độ hài lòng của 98 hộ dân sống tại hai khu tái định cư Hồng Thượng và Hồng Hạ. Kết quả nghiên cứu đã cho thấy có sự khác nhau về mức độ hài lòng của người dân tại hai khu TĐC. Tại khu TĐC Hồng Thượng người dân thấy không hài lòng về địa điểm bố trí TĐC, nhà ở được xây dựng thiếu chất lượng đã bị hư hỏng, nứt nẻ xuống cấp, thiết kế xây dựng không phù hợp với phong tục, tập quán của người dân địa phương, với chỉ số đánh giá hài lòng là 1,07. Trong khi đó, tại khu TĐC xã Hồng Hạ người dân lại thấy hài lòng về điểm bố trí TĐC và diện tích đất ở được cấp, với chỉ số đánh giá hài lòng là 4,19. Kết quả nghiên cứu của đề tài sẽ giúp cho chính quyền cũng như chủ đầu tư dự án nắm rõ những điểm không hài lòng của người dân để có hướng giải quyết phù hợp nhằm đảm bảo cuộc sống ổn định cho người dân tại nơi tái định cư.

This project responds to an ongoing discussion in scholarship that identifies and analyzes the ideological functions of computer interfaces. In 1994, Cynthia Selfe and Richard Selfe claimed that interfaces are maps of cultural information and are therefore ideological (485). For Selfe and Selfe and other scholars, these interfaces carried a colonial ideology that resulted in Western dominance over other cultures. Since this early scholarship, our perspectives on interface have shifted with changing technology; interfaces can no longer be treated as having persistent and predictable characteristics like texts. I argue that interfaces are interactions among dynamic information that is constantly being updated online. One of the most prominent ways users interact with information online is through the use of search engines such as Google. Interfaces like Google assist users in navigating dynamic cultural information. How this information is arranged in a Google search event has a profound impact on what meaning we make surrounding the search term. In this project, I argue that colonial ideologies are upheld in several Google search events for the term "Benghazi, Libya." I claim that networked connection during Google search events leads to the creation and sustainment of a colonial ideology through patterns of arrangement. Finally, I offer a methodology for understanding how ideologies are created when search events occur. This methodology searches for patterns in connected information in order to understand how they create an ideological lens.

[pt] A pesquisa considera a perspectiva da federação tridimensional que estabeleceu o município como ente federado a partir da Constituição Federal de 1988 e da LDBEN 9.394 de 1996. A intensificação da municipalização do ensino fundamental neste contexto, com aumento no número de matrículas de estudantes em idade obrigatória de escolarização, implicou em novas responsabilidades para as equipes gestoras locais, tornando seu trabalho mais complexo. A pesquisa buscou i) compreender como redes públicas municipais de ensino se organizam do ponto de vista administrativo para atender ao público matriculado em suas escolas e ii) investigar os arranjos institucionais e as ações empreendidas pelos órgãos gestores e suas possíveis relações com os diferentes perfis de rendimento das redes de ensino em termos de qualidade e equidade educacional. O estudo, de natureza quantitativa, complementado por estudos de caso, foi realizado tendo como referenciais os estudos da área de gestão e política educacional. A análise foi realizada a partir de três categorias-chave: contexto socioeducacional, arranjo institucional e focalização da gestão. A partir do estudo realizado observou-se que há compromisso das equipes locais e esforços expressivos, ainda que diferenciados em cada caso, empreendidos para garantir a matrícula e a frequência com sucesso escolar dos alunos das redes municipais de ensino. Contudo, as interferências externas, em especial da política local e limitações de natureza técnica, em contextos socioeconômicos de parcos recursos das famílias e da rede pública de ensino dificultam a elaboração de políticas educacionais que logrem promover qualidade com equidade educacional. / [en] This research considers the federation three-dimensional perspective which established that the municipalities are enabled as federated entities since our Brazilian Constitution from 1988 and our LDBEM from 1996. The increasing numbers in decentralization of primary education and the increasing enrollment rates among students to whom enrollment in mandatory has brought new responsibilities and has made work more complex for educational administrators. This research aimed to i) comprehend how our public networks administratively organized themselves in order to cope with more enrollments and the new demands and ii) to investigate the institutional arrangements, the actions taken by managers and the possible relations among the various achievement profiles of students in regards to educational quality and equity. This quantitative research was complemented by case studies and used studies in educational management and policy as reference. The analysis was made from three keywords: social and educational context, institutional arrangements and management focus. From this study, it was observed that there is commitment and strong effort in order to guarantee enrollments to students and a successful school attendance. However, some external interference, especially the local policies, the technical limitations, the little resource from families and from our public network make more difficult to elaborate educational policies which effectively promote educational quality and equity.

<p>This thesis deals with combinatorial and geometric aspects of linear optimization, and consists of two parts.</p> <p>In the first part, we address a conjecture formulated in 2008 and stating that the largest possible average diameter of a bounded cell of a simple hyperplane arrangement of n hyperplanes in dimension d is not greater than the dimension d. The average diameter is the sum of the diameters of each bounded cell divided by the total number of bounded cells, and then we consider the largest possible average diameter over all simple hyperplane arrangements. This quantity can be considered as an indication of the average complexity of simplex methods for linear optimization. Previous results in dimensions 2 and 3 suggested that a specific type of extensions, namely the covering extensions, of the cyclic arrangement might achieve the largest average diameter. We introduce a method for enumerating the covering extensions of an arrangement, and show that covering extensions of the cyclic arrangement are not always among the ones achieving the largest diameter.</p> <p>The software tool we have developed for oriented matroids computation is used to exhibit a counterexample to the hypothesized minimum number of external facets of a simple arrangement of n hyperplanes in dimension d; i.e. facets belonging to exactly one bounded cell of a simple arrangement. We determine the largest possible average diameter, and verify the conjectured upper bound, in dimensions 3 and 4 for arrangements defined by no more than 8 hyperplanes via the associated uniform oriented matroids formulation. In addition, these new results substantiate the hypothesis that the largest average diameter is achieved by an arrangement minimizing the number of external facets.</p> <p>The second part focuses on the colourful simplicial depth, i.e. the number of colourful simplices in a colourful point configuration. This question is closely related to the colourful linear programming problem. We show that any point in the convex hull of each of (d+1) sets of (d+1) points in general position in R^d is contained in at least (d+1)²/2 simplices with one vertex from each set. This improves the previously established lower bounds for d>=4 due to Barany in 1982, Deza et al in 2006, Barany and Matousek in 2007, and Stephen and Thomas in 2008.</p> <p>We also introduce the notion of octahedral system as a combinatorial generalization of the set of colourful simplices. Configurations of low colourful simplicial depth correspond to systems with small cardinalities. This construction is used to find lower bounds computationally for the minimum colourful simplicial depth of a configuration, and, for a relaxed version of the colourful depth, to provide a simple proof of minimality.</p> / Doctor of Philosophy (PhD)

在音樂中，組曲是一種特別的創作形式。組曲將多首音樂段落組合排列，並且在音樂段落之間加入間奏，形成一首音樂組曲。組曲的編曲重點在於音樂段落的編排順序及段落之間的連結。平時在宴會、舞會、餐廳、賣場等場合中，往往都會連續播放多首流行音樂。利用電腦編曲自動產生流行音樂組曲，將可提升播放音樂的銜接與流暢感。 因此，本研究利用資料探勘技術及音樂編曲理論，將多首音樂重新改編成一首組曲。系統首先將每首音樂分段並找出每首音樂的代表段落。接著，系統根據代表段落間的相似度編排順序。最後，為了達到組曲中音樂段落連接的流暢性，我們以模型訓練的方式在段落連結間加入間奏。系統從訓練資料學習產生旋律發展、和弦進程與節奏的模型，接著分析代表段落的動機、旋律、和弦及節奏，使得組曲編曲後的段落連結更為流暢且完整。本研究以流行音樂鋼琴伴奏曲為測試資料，我們分別邀請三十四位受過音樂訓練與未受音樂訓練的測試者，針對本研究所提出的鋼琴伴奏節奏辨識、代表段落萃取、段落順序編排及間奏產生，評估其效果。實驗結果顯示，本研究所提出的順序編排與間奏產生技術，對於組曲的流暢感，有著相當大的幫助。 / In music, a medley is an organized piece composed from segments of existing pieces. Ordering and bridge for connection between segments are the important elements for medley arrangement. Automatic medley arrangement is helpful for playing a set of music continuously which is common in banquet, party, restaurant, shopping mall, etc.. This thesis aims to develop the automatic medley arrangement method by using data mining techniques and music arrangement theory. The proposed method first segments each music and discovers the significant segment from each music. Then, the linear arrangement based on the similarities between significant segments is generated. Finally, in order to connect segments smoothly in the medley, the bridge between two segments is generated and inserted by using model training. Three models, melody progression, chord progression and rhythm models are learned from training data. For the experiments, testing data is collected from popular piano music and thirty-four people are invited to evaluate the effectiveness of the rhythm recognition of accompaniment, the extraction of significant segment, the linear arrangement of segments, and the creation of bridge. Experimental results show that the proposed medley arrangement method performs well.

Ce travail se concentre sur comment un acteur justifierait ses actions dans des 'environnements hétérogènes et fragmentés. Le but est de démontrer qu’en l’absence d’un principe d’accord contraignant les actions des acteurs, les relations entre les partenaires d’action égaux basculeraient dans la polyarchie et celles entre les partenaires d’action inégaux basculeraient respectivement dans l’arrangement, la discorde et finalement, la violence. A cette fin, cette recherche se concentre sur les politiques mandataires britanniques en Irak à travers une étude de traitement du mouvement nationalitaire kurde dans la wilaya de Mossoul dans une période s’étendant du 30 octobre 1918 au 5 juin 1926. Le 30 octobre 1918 est la date à laquelle l’Armistice de Moudros a été signée entre les Alliés et l’Empire ottoman (à la fin de la Première Guerre mondiale) suite à laquelle les Britanniques occupèrent Mossoul. Le 5 juin 1926 correspond à la date de la signature du Traité d’Angora qui devait régler la question de la frontière turco-irakienne, connue aussi comme la Question de Mossoul / This study focuses on how an actor justifies its actions in heterogenous and fragmented environments. It aims at proving that in the absence of a principle of agreement constraning the actors’ actions, the relations between equal partners of action turn into polyarchy whilst those between inequal ones end in arrangement, contention and finally, violence. To this end, this research concentrates on the British mandatory policies in Iraq through the management of Kurdish nationalist movement in the wilaya of Mosul from 30rd October 1918 to 5th 1926. The 30rd October 1918 is the date of the signature of Armistice of Mudros between the Allies and the Ottoman Empire at the end of the First World War. It is in the aftermath of this armistice that the British occupied Mosul. In 5th 1926, Turkey and Great Britain signed the Treaty of Angora which settled the question of frontier between Turkey and Irak, a question which is also known as Question of Mosul

本論文首先介紹臺灣老人的居住安排基本概況。接著，以交換理論與家庭價值觀，分析居住安排的轉換。同時，從經濟因素與需要因素的推拉作用以及家庭價值觀與交換理論，分析老人「移與子女居」和「子女回居」。再接著，應用相同樣本探討年歲增長與居住安排的關係，分析一群老人從初老經過中老到老老三個階段的居住安排。最後，以人與環境一致模式、基本生活需求滿足假說，分析老人居住安排滿意與否的改變。 以往討論老人居住安排的轉換，大多以家庭價值觀解釋，強調感情因素，當老人有最大需要時，例如，健康惡化或從有偶變成無偶，更可能發生轉換為與子女同住。但現代化社會，經濟因素轉趨重要，可能需要以交換理論補強。因此，本論文使用我國行政院衛生署與密西根大學合作之「臺灣地區中老年身心社會生活狀況長期追蹤調查」縱斷面調查資料，進行老人居住安排轉換的分析研究，觀察居住安排轉換行為，以檢視這兩種觀點對於居住安排轉換的解釋力。又，以往的相關研究大多以靜態變數為解釋變數，本論文貢獻主要在於以動態的變數－相關變數前後期的變化－為解釋變數，檢視其對老人居住安排轉換的影響。結果發現：以家庭價值觀或以交換理論解釋老人居住安排的轉換，都獲得部分支持；但沒有足夠的證據支持健康惡化或從有偶變無偶是影響老人轉換為與子女同住的關鍵因素；相反地，與交換理論相關的重大經濟決策權的改變變得比較重要，造成更可能發生轉換為不與子女同住或與子女同住。隱含著家庭價值觀對老人居住安排轉換的影響逐漸式微，而交換理論的影響力則越來越強，可彌補以家庭價值觀解釋之不足。 本論文亦使用縱斷面調查資料，以相關變數前後期的變化為解釋變數，檢視臺灣老人從不與子女同住變成「移與子女居」及「子女回居」的影響因素。結果隱含老人正向經濟因素的轉變更可能發生「子女回居」，需要因素及負向經濟因素的轉變則更可能發生「移與子女居」，而且沒有證據足認健康狀況轉差是影響轉換為與子女同住的關鍵因素。 有別於以往許多老人居住安排的文獻常將65歲以上的人當作一個群體，或有的橫斷面研究使用不同樣本，抑或即使以縱斷面研究亦使用不同樣本，進行老化研究，本論文利用相同樣本縱斷面研究分析老年人在初老、中老、老老階段的居住安排，回答「隨著年齡的增長，老人與子女共住的比例是呈U型或直線下降的關係？」、「老化對居住安排有何影響？」的問題。研究結果顯示隨著年齡的增長，老人與子女共住的比例呈直線下降。本論文發現一些因素在某階段有顯著影響，而在其他階段未發現有顯著影響，此即與老化有關；除此，對三個階段的居住安排均發生顯著影響的因素，其影響程度亦隨著年齡的增長而有不同，均為預測老人各階段居住安排決定的良好指標。 本論文為檢視究竟何因素影響老人居住安排滿意與否之改變，使用縱斷面調查資料，應用人與環境一致和基本生活需求滿足之理論基礎，以動態的變數－相關變數前後期的改變－為解釋變數，檢視其影響。結果發現：以人與環境一致或基本生活需求滿足，解釋居住安排滿意與否之改變，都獲得部分支持，同時，「愛屋及烏」假說亦獲得支持。顯示居住安排滿意與否之改變，主要歸因於環境與個體間之一致及合適與否。 總結而言，老人隨著年歲增長，居住安排從滿意變為不滿意者的比例增加，健康狀況亦呈直線下降，但不與子女同住的比例遞增，與子女同住的居住安排則呈直線下降，許多影響因素已顯示老人由家庭照護的傳統價值日漸式微。無論老人採行何種居住安排，理應以提高居住安排滿意度，提昇老人福祉為依歸。此際，除了由政府提出有效對策以為改善之外，老人宜自求多福，例如，改善居住環境、移居良好醫療環境，家庭重大決策放手由子女承擔，多多參與社交性或拜訪親友、鄰居的活動，快樂邁向成功老化。 / This dissertation, firstly, introduces the basic overview of living arrangements of the elderly in Taiwan. Then, it analyzes the transitions in living arrangements among elderly of family values and exchange theory, meanwhile, it also analyzes “moving to be with children” and “returning to the nest” from needs factors and economic factors as well as family values and exchange theory. Then, it uses a panel study to examine the living arrangements of young-old, old-old, and oldest-old. Finally, it applies a theoretical basis of person-environment congruence and basic-needs content to analyze the changes in satisfaction with living arrangements of the elderly. The value placed on family was often used to explain the influence on living arrangements transitions in previous literature. Yet economic factors have become important in modern society, therefore we need to use exchange theory to strengthen the explanation on transitions. This dissertation, therefore, attempts to compare these two explanations through analyzing transitions, and to examine the effects of these two viewpoints on transitions. Using a longitudinal data source, the Survey of Health and Living Status of the Elderly in Taiwan, produced by the Department of Health (Taiwan) and the University of Michigan, a binomial logit model is used to observe the behavior of transitions. The contribution of this dissertation mainly lies in taking the dynamic variables, the changes of related variables between baseline and follow-up, as independent variables to examine the influence on the transitions. Empirical results show that both family value and exchange theory cause the living arrangements transitions, but lack evidence to prove that a senior’s health deterioration or the loss of a spouse was the major determinant of the transition to live with children. Contrarily, transitions of living arrangements are more likely to occur when a senior changes her/his role as the economic decision-maker into the non economic decision-maker of the household or vice versa. That implies the influence of family values on transitions is decreasing, and the influence of exchange theory is increasing. This dissertation also uses a longitudinal data source and takes the changes of related variables between baseline and follow-up as independent variables to examine what factors are associated with “moving to be with children” and “returning to the nest” among those living apart from children at baseline of Taiwanese seniors. Empirical results imply that “returning to the nest” is more likely to occur when a senior’s positive economic factors are changed; while “moving to be with children” is more likely to occur when a senior’s needs factors and negative economic factors are changed, and lacking evidence to prove that health deterioration was the major determinant of the transition to live with children. Most previous research on elderly living arrangements examined all people aged 65 and over as a whole. Some cross-sectional studies on aging employed different samples, as did some longitudinal studies. This dissertation examines the living arrangements of young-old, old-old, and oldest-old in Taiwan. A panel study was used to answer the following questions: Is the proportion of coresidence with increased age U-shaped or decreased linearly? What influence does aging have on living arrangements? Analytical results show that the proportion of coresidence decreased linearly among the same samples for the young-old, old-old, and oldest-old. Empirical results show that some factors were significant at some stages, while not significant at other stages, that is, they were affected by aging. Additionally, some factors related to living arrangements for all three age groups, and their effects differed with increased age. All of them are good indicators in predicting the determinants of elderly living arrangements for the three groups. This dissertation also uses a longitudinal data source, applies a theoretical basis of person-environment congruence and basic-needs content, and takes the dynamic variables, the changes in related variables between the baseline and follow-up, as independent variables to examine the determinants of changes in satisfaction with living arrangements of the elderly. Empirical results indicate that both person-environment congruence and basic-needs content partially cause changes in satisfaction with living arrangements, and the “love me, love my dog” hypothesis is also fulfilled. This dissertation suggests that changes in satisfaction with living arrangements are mainly attributed to the congruence or fit between the environment and the individual. Summarily, the proportion of dissatisfaction with living arrangements increases as age increases, the condition of health worsened linearly and the proportion of living with children is decreased with increased age, many factors have been implied the influence of traditional values on family care is decreasing. No matter what kind of living arrangement the elderly adopted, they should improve the living arrangement satisfaction, and enhance the welfare. At this time, beyond the improvements through effective measures of the government, the elderly should fend for themselves by improving the living environment, moving to a good medical environment, transferring the power of decision-making to children, and more involving in sociability or visiting relatives, friends and neighbors. And then they achieve successful aging happily.

Les alliages à base de Ni-Mn-In ont attiré une attention considérable en raison de leurs propriétés multifonctionnelles depuis leur découverte en 2004, telles que l’effet de mémoire de forme métamagnétique (Metamagnetic shape memory effect MMSME), l'effet magnétocalorique (MCE) et l'effet de magnétorésistance (MR). Cependant, certaines connaissances fondamentales sur ces alliages manquent toujours jusqu'à présent, telles que la structure cristalline de la martensite, les caractéristiques cristallographiques de microstructure et de transition magnétostructurale. Dans cette thèse, les caractéristiques cristallographiques, les comportements mécaniques et les propriétés magnétiques des alliages Ni-Mn-In base ont été étudiés théoriquement et expérimentalement. Tout d'abord, les structures cristallines des alliages Ni-Mn-In ont été déterminées avec précision par la méthode de Rietveld dans le cadre de la théorie du superespace. Ensuite, la microstructure de la martensite, notamment l'organisation et l'interface des variantes, ainsi que les caractéristiques cristallographiques de la transformation martensitique, telles que les relations d'orientation (OR), le chemin de déformation de la transformation et la compatibilité géométrique entre l'austénite et la martensite, ont été systématiquement étudiés. Enfin, avec cette connaissance fondamentale sur les alliages Ni-Mn-In, les comportements et les mécanismes de sélection /réarrangement des variantes de martensite sous deux types de stratégies de chargement mécanique, à savoir le chargement à l'état martensitique et le chargement durant la transition structurelle, et les effets du recuit sur l'effet MCE et les pertes d'hystérésis associées ont été explorées. Les principaux résultats sont les suivants. La martensite modulé a une structure cristalline incommensurable avec la structure cristalline 6M et le groupe de superespace I2/m(α0γ)00 qui peut être approximée par un modèle de superstructure de multiplicité 3 dans l'espace à tridimensionnel. La microstructure de martensite est en forme de plaques et auto-organisée en colonies. Chaque colonie a quatre variantes d'orientations distinctes. Le maximum de 6 colonies distinctes et 24 variantes peut être généré à l'intérieur d'un grain austénitique. Bien que jusqu'à 14 types de relations de maclage sont proposées dans le cadre des théories cristallographiques de transformation martensitique, seuls trois types de relations de maclage sont généralement observés, à savoir des macles de type I, type II et composées. Les interfaces des variantes sont définies à l'échelle mésoscopique par leur plan de maclage K1 correspondant. Cependant, à l'échelle atomique, la macle de type I a une interface cohérente, alors que celles de type-II et les macles composées ont des interfaces étagées. Les deux relations d'orientations K-S et Pitsch sont appropriés pour décrire la correspondance de réseau entre austénite et martensite dans les alliages Ni-Mn-In. Cependant, le chemin de déformation lié à la relation de Pitsch est mis en évidence pour être efficace pour la déformation de la structure. Avec le chemin de transformation déterminé, le mécanisme sous-jacent de l'organisation des variantes est révélé. À travers la transformation martensitique, en dépit de l'existence d'une relativement large couche contrainte (de l'ordre de 20 nm), le plan d'habitat est bordé par une variante de martensite simple avec l'austénite plutôt que la structure généralement observée "en sandwich", ce qui suggère une relativement bonne compatibilité géométrique entre les phases correspondantes. Pour le chargement en compression à l'état martensitique, l'arrangement des variantes est réalisé par des processus de démaclage. Il est démontré que l'état de variante unique dans certaines colonies pourrait être obtenu lorsque l'orientation de chargement est située dans la zone de Facteur de Schmid (SF) positif commune pour les trois systèmes de démaclage. [...] / Ni-Mn-In based alloys have attracted considerable attention due to their multifunctional properties since its discovery in 2004, such as metamagnetic shape memory effect (MMSME), magnetocaloric effect (MCE) and magnetoresistance (MR) effect. However, some fundenmental knowledge on these alloys is still missing until now, such as crystal structure of martensite, crystallographic features of microstructure and magnetostructural transition. In this dissertation, the crystallographic features, mechanical behaviors and magnetic properties of Ni-Mn-In based alloys were studied theoretically and experimentally. First, the crystal structures of Ni-Mn-In alloys were accurately determined by Rietveld method in the frame of superspace theory (Chapter 3). Then, the microstructure of martensite (Chapter 4), such as variant organization and interface structure, and the crystallographic features of martensitic transformation, such as orientation relationship (OR), transformation strain path and geometrical compatibility between austenite and martensite, were systematically studied (Chapter 5). Finally, with this fundamental knowledge on Ni-Mn-In alloys, the behaviors and mechanisms of martensite variant rearrangement/ selection under two kinds of mechanical loading strategies, i.e. loading at martensite state and loading across the structural transition, and the effects of annealing on MCE and its related hysteresis loss were explored (Chapter 6). The main results are as follows. The modulated martensite has an incommensurate 6M crystal structure with superspace group I2/m(α0γ)00 that can be approximated by a three-fold superstructure model in the three-dimensional space. The microstructure of martensite is in plate shape and self-organized in colonies. Each colony has four distinct orientation variants. The maximum of 6 distinct colonies and 24 variants can be generated within one austenite grain. Although as many as 14 kinds of twin relations are suggested in the frame of crystallographic theories of martensitic transformation, only three types of twin relations are generally detected, i.e. type-I, type-II and compound twin. Variant interfaces are defined by their corresponding twinning plane K1 at mesoscopic scale. However, at atomic scale, the type-I twin has a coherent interface, whereas type-II and compound twins have “stepped” interfaces. Both the K-S and Pitsch ORs are appropriate to describe the lattice correspondence between austenite and martensite in Ni-Mn-In alloys. However, the strain path related to the Pitsch relation is evidenced to be the effective for the structural distortion. With the determined transformation path, the underlying mechanism of variant organization is revealed. Across the martensitic transformation, despite the existence of a relative wide stressed layer (around 20 nm), the habit plane is bordered by single martensite variant with austenite rather than the generally observed “sandwich-like” structure, implying a relative good geometrical compatibility between the corresponding phases. For compressive loading at martensite, variant arrangement is realized by the detwinning process. It is evidenced that a single variant state in some colonies can be obtained when the loading orientation is located in the common positive Schmid factor (SF) zone of the three detwinning systems. For loading across the structural transition, the prestrain is obtained by variant selection in which the number of colonies is significantly reduced and the variant organization within colony is greatly changed. The SF for transformation strain path is introduced to evaluate the possible selection of variants. Heat treatment can significantly enhance the magnetic entropy change ΔSM but simultaneously increase the magnetic hysteresis loss. For ΔSM, the chemical ordered degree should play a prominent role [...]
