Analysis of Energy Flexibility Strategies for Residential and Commercial Building Clusters Through Simulation
No full textRÉSUMÉ: Puisque l'électrification dans divers secteurs contribue à l'augmentation de la demande d'électricité, les réseaux peuvent être confrontés à des périodes de pointe plus critiques que jamais. Les conditions météorologiques extrêmes ne font qu'aggraver le problème. Les fortes chaleurs entraînent une augmentation de la demande d'électricité pour le refroidissement et, dans les régions froides où la proportion du chauffage électrique est élevée (comme au Québec), les basses températures entraînent une augmentation de la demande d'électricité pour le chauffage. La gestion de l'énergie parmi les consommateurs est donc devenue de plus en plus pertinente, non seulement pour réduire la consommation annuelle mais aussi pour contrôler quand l’électricité est utilisée, faisant de la flexibilité un objectif important. Les bâtiments représentent une grande partie de la consommation totale d'électricité. Si leur énergie est bien contrôlée, ils peuvent être des acteurs majeurs de la flexibilité. Cette possibilité permet aux bâtiments de participer à la gestion de la demande, par exemple en réduisant leur consommation pendant des événements de pointe. Lorsque les bâtiments sont regroupés en grappes (clusters), les efforts de flexibilité donnent des résultats agrégés et présentent un potentiel élevé pour les réseaux électriques. La flexibilité dans les grappes de bâtiments est le sujet d'analyse de ce mémoire, qui explore différentes stratégies de flexibilité dans des groupes composées de différents types de bâtiments et leurs caractéristiques. Pour étudier ce sujet, le logiciel de modélisation TRNSYS a d’abord été utilisé pour simuler les besoins en énergie d'une grappe de 2400 maisons unifamiliales avec différents niveaux d'isolation, des points de consigne de chauffage et de profils de charge. Quatre stratégies de flexibilité ont été testées, qui ont ajusté les points de consigne pour le chauffage des locaux et de l'eau dans la grappe. Ces stratégies ont permis de réduire la pointe de 15 à 25 % par logement pendant les heures des événements de pointe. Bien que de fortes réductions de puissance aient été constatées pendant les heures des événements de pointe, des effets de rebond ont été créés, qui ont été atténués par des ajustements des taux de participation. Pour approfondir l'étude, une plus grande variété a été introduite dans la grappe par l'ajout de bâtiments commerciaux/institutionnels (CI), qui ont des systèmes de chauffage hybrides gaz-électricité. Pour ce faire, un modèle TRNSYS initial a été créé sur la base d'un bâtiment CI réel au Québec, en utilisant des données opérationnelles et des caractéristiques physiques. ABSTRACT: As electrification in various sectors contributes to increasing power demands, grids may face increased strain and more critical peak periods than ever before. Weather extremes add to the problem, as high heat drives up cooling power demands, and in cold regions with high shares of electric heating, such as in Quebec, low temperatures drive up heating power demands. Managing power across electric consumers has thus become increasingly relevant, not only to reduce the annual energy use but also to control when electricity is used, making flexibility an important goal. Buildings, which represent considerable shares of electric consumption, can be major participants in achieving flexibility, if their loads are well controlled. Having this ability allows buildings to be involved in demand side management, such as through demand response (DR) programs. When buildings are grouped into clusters, flexibility efforts have aggregated results and present an even larger potential for electric grids. Flexibility in building clusters is the subject of analysis throughout this thesis, which explores different flexibility strategies in clusters composed of varying building types and characteristics. To investigate this topic, TRNSYS has been firstly used to simulate the power requirements of a cluster of 2400 residential homes of varying insulation levels, HVAC schedules, and load profiles. Four flexibility strategies were tested, which adjusted the space and water heating setpoints in the cluster and were able to achieve power reductions of 15-25 % per home during the DR hours. Although large power reductions were found during the DR hours, large rebound peaks were created, which were mitigated through adjustments in the participation rates. To further the investigation, more variety was introduced in the cluster though the addition of commercial/institutional (CI) buildings, which have hybrid gas-electric heating systems. To make this addition, an initial TRNSYS model was created based on a real CI building in Quebec, using operational data and physical characteristics. Modifications were then made to then create 30 CI buildings variations based on this initial model. Thus the total cluster, 2430 buildings, underwent flexibility strategy testing, where the CI buildings made use of their hybrid heating system by fuel switching during DR events. The total cluster achieved peak reductions up to 36% during DR hours, with only a small increase in peak over the average DR day. The benefits of flexibility in clusters, specifically in clusters containing varying building types and energy sources, are highlighted in this research, thus contributing to the body of work in this field of study

The Evolution of Leftism in Peruvian Literature from the 20th Century to the Contemporary Era: José Carlos Mariátegui, José María Arguedas, and Antonio Gálvez Ronceros
No full textMariátegui, Arguedas, and Gálvez Ronceros represent important leftist voices in Peruvian literature that used their writings as a tool for political and social change. With this scholarship it is my aim to present an in-depth analysis on the origins of leftism in the context of Peruvian literature and the changes it experienced over time. Given the pluralism in the way the concept of leftism is interpreted and understood today, this research also provides a guide on how it should be defined in Peru’s context, given that mere importation of European leftism does not fully explain the unique characteristics of Peruvian leftism. In chapter one, I argue that the José Carlos Mariátegui played a significant role in shaping Peruvian society by championing a form of socially engaged leftist literature that reflected the realities of life for the working class and marginalized communities of Peru. To this day, Mariátegui’s ideas continue to influence leftist writers in Peru and in all Latin America, as well. While his role as a leftist author must not be undermined, this research also addresses the need that exists today to reexamine his figure and highlight the shortcomings that are found in his writings; namely, the underrepresentation of women and racial stereotypes used against Asians and people of African descent. In chapter two, I study the life and work of José María Arguedas who played a significant role in shaping Peruvian literature by giving voice to the experiences of indigenous people and challenging the dominant literary and cultural norms of Peru’s Andean region. His works deal with themes such as identity, culture, and oppression while insisting on a uniquely Andean expression of leftist thought that highlights the importance of indigenous spirituality, customs, and traditions. The final chapter of the dissertation is one of the first works to present an in-depth analysis of the role and writings of a contemporary leftist Peruvian author, Antonio Gálvez Ronceros. Gálvez Ronceros has utilized his work to give a greater representation to Peru’s most marginalized groups, namely AfroPeruvians, and mestizo campesinosliving on Peru’s southern coast. Leftist literature in Peru has played an important role in shaping the country’s political and cultural landscape, and it continues to be an important means of political and social resistance and activism. By analyzing the works of these three authors, we are given a unique opportunity to not only study the origins of leftism in Peru, but to also highlight its evolution over time to better understand its continued influence on Peruvian society
Transnacionalne in transkulturne prvine v poetiki Milene Merlak Detela
No full textPrispevek v okviru teoremov feministične teorije, kulturnih študij in migracijskih teorij predstavi analizo literarnega opusa Milene Merlak Detela z vidika preseganja tradicionalnih konstruktov, vezanih na koncepte meja, nacionalne in etnične pripadnosti ter kulture. Tovrstno dojemanje je pogojeno z migrantsko izkušnjo avtorice ter njenim aktivnim vključevanjem v dva nacionalna in kulturna imaginarija. Obravnavana poetika na subverziven način presega koncepte o fiksnih identitetah ter rigidnosti meja, nacionalnosti, etničnosti in kulture.Within the framework of feminist theory, cultural studies and migration theories, the article presents an analysis of Milena Merlak Detela’s literary work, from a perspective that goes beyond traditional constructs relating to the concepts of borders, nationality, ethnic
origin and culture. This type of perspective is conditioned by the migrant experience of the author and her active involvement in two national and cultural imaginaries. In a subversive way, her poetics transcended the concepts of fixed identities, the rigidity of borders, nationality, ethnicity and culture
Mediation in Georgia. Development perspectives and challenges
No full textThe article discusses the legal and systemic issues of the creation of a modern mediation institution in Georgia. It discusses Georgia’s historic experience traditions of settlements of disputes by means of peaceful methods, part of which are still preserved in the high mountainous regions of the country. In 2013, the country was also introduced to the mediation for settlement of collective labour disputes, which is implemented by active involvement from the government. Already existing statistics demonstrate that mediation in the given sphere is effective and actually serves for the settlement of disputes between employers and groups of employees. In 2019, Georgia adopted the law on mediation, which regulates the issue of private mediation conduction andexecution of achieved agreements. Mediators training and professional development system were created. By the adoption of the given Law ended the almost eightyear phase of mediation legal and institutional regulation,which, according to the opinion of the author of the article, was a process prolonged in time. Unified Law could have been adopted at the early stage of the reform which would have made the process of extensive usage of mediation in the country faster. As reason for introduction of mediation institution in Georgia is named the obligations of the country in the process of integration with the European Union, overloading of civil courts in the country and prolonged disputes.The article discusses the legal and systemic issues of the creation of a modern mediation institution in Georgia.

The persimmon genome reveals clues to the evolution of a lineage-specific sex determination system in plants
No full textMost angiosperms bear hermaphroditic flowers, but a few species have evolved outcrossing strategies, such as dioecy, the presence of separate male and female individuals. We previously investigated the mechanisms underlying dioecy in diploid persimmon (D. lotus) and found that male flowers are specified by repression of the autosomal gene MeGI by its paralog, the Y-encoded pseudo-gene OGI. This mechanism is thought to be lineage-specific, but its evolutionary path remains unknown. Here, we developed a full draft of the diploid persimmon genome (D. lotus), which revealed a lineage-specific whole-genome duplication event and provided information on the architecture of the Y chromosome. We also identified three paralogs, MeGI, OGI and newly identified Sister of MeGI (SiMeGI). Evolutionary analysis suggested that MeGI underwent adaptive evolution after the whole-genome duplication event. Transformation of tobacco plants with MeGI and SiMeGI revealed that MeGI specifically acquired a new function as a repressor of male organ development, while SiMeGI presumably maintained the original function. Later, a segmental duplication event spawned MeGI's regulator OGI on the Y-chromosome, completing the path leading to dioecy, and probably initiating the formation of the Y-chromosome. These findings exemplify how duplication events can provide flexible genetic material available to help respond to varying environments and provide interesting parallels for our understanding of the mechanisms underlying the transition into dieocy in plants.
Author summary Plant sexuality has fascinated scientists for decades. Most plants can self-reproduce but not all. For example, a small subset of species have evolved a system called dioecy, with separate male and female individuals. Dioecy has evolved multiple times independently and, while we do not understand the molecular mechanisms underlying dioecy in many of these species yet, a picture is starting to emerge with recent progress in several dioecious species. Here, we focused on the evolutionary events leading to dioecy in persimmon. Our previous work had identified a pair of genes regulating sex in this species, called OGI and MeGI. We drafted the whole genome sequence of diploid persimmon to investigate their evolutionary history. We discovered a lineage-specific whole-genome duplication event, and observed that MeGI underwent adaptive evolution after this event. Transgenic analyses validated that MeGI newly acquired a male-suppressor function, while the other copy of this gene, SiMeGI, did not. The regulator of MeGI, OGI, resulted from a second smaller-scale segmental duplication event, finalizing the system. This study sheds light on the role of duplication as a mechanism that promote flexible genes functions, and how it can affect important biological functions, such as the establishment of a new sexual system
Neoliberalism and Homelessness: Analysis of Homeless People\u27s Stories of Their Situation
No full textV diplomskem delu razmišljam o povezavi med neoliberalnimi politikami in stigmo, ki jo doživljajo brezdomci, začenši v temeljih (neo)liberalizma. Postavim neoliberalen okvir, znotraj katerega lahko kasneje pojmujem brezdomne osebe v sodobni družbi. Analizo opiram tudi na psihološke ideale liberalizma, ki jih je zapisal Beauvois leta 2000 v svojem delu Razprava o neoliberalni sužnosti. Mednje spada individualizacija odgovornosti posameznice_ka za svoja dejanja in svoje izhodišče, pa tudi ponotranjanje oziroma internalizacija te in preostalih vrednost, ki jih avtor definira za liberalne, sama pa jih vnesem še v neoliberalni kontekst. Internalnost predstavim kot družbeno normo. Nadalje kontekstualiziram brezdomnost kot družben fenomen v času in prostoru. Razmišljam o dejavnikih tveganja za nastanek brezdomne situacije in značajski stigmatizaciji, ki po Goffmanu pritiče marginalizirani brezdomni osebi. Na primeru kratkih izjav brezdomnih oseb časopisa Kralji ulice razmišljam, kako brezdomne osebe vidijo sebe, kako nanje gledajo drugi in kakšen vpliv ima to, socialno sebstvo, na njihovo predstavo o sebi.In my bachelor thesis, I am thinking about the connection between neoliberal policies and the stigma experienced by the homeless, starting from the foundations of (neo)liberalism. I set up a neoliberal framework within I later understand homeless people as a part of modern society. I also base my analysis on the psychological ideal of liberalism, which Beauvois described in 2000 in his work Traité de la servitude libérale. These include the individualization of responsibility for one\u27s actions and one\u27s starting point, as well as the internalization of these and other values, which the author defines as liberal, and which I myself bring into the neoliberal context. I present the internal value as a social norm. I further contextualize homelessness as a social phenomenon in time and space. I am thinking about the risk factors for the emergence of a homeless situation and the significant stigmatization that, according to Goffman, befalls a marginalized homeless person. On the example of short statements by homeless people in the newspaper Kralji ulice, I am thinking about how homeless people see themselves, how society view them and what influence this, the social self, has on their self-image
