Abstract: The objective of this part of the project is to establish the statistical framework of predicting extremes
by a seasonal forecast system. This report summarises some preliminary results. Nonstationary extreme
value statistics of cold temperatures in Kiev has been evaluated, with some index of the NAO as a covariate
responsible for nonstationary conditions. We found that while mean DJF temperatures depend
more on negative values of an NAO index, some extremal features depend more on its positive values.
Furthermore, the lowest temperatures occur for intermediate values of the NAO index.The Blue-Action project has received funding from the European Union's Horizon 2020 Research and Innovation Programme under Grant Agreement No 727852 www.blue-action.e
Computational Methods for Transition States and Pathways in Rare Events
No full textBased on the calculation of transition states and the identification of transition paths, this book aims to provide a comprehensive guide to understanding and simulating rare events.
The author introduces both fundamental concepts of transition states and pathways and advanced computational techniques, focusing on Gentlest Ascent Dynamics (GAD) and its variants. In particular, she explores enhanced numerical methods such as the convex splitting method and the Scalar Auxiliary Variable (SAV) approach within the Iterative Minimization Formulation (IMF). In addition, the book applies these methods to real-world problems, highlighting the string method and the geometric Minimum Action Method (gMAM) for computing transition paths.
The book is written for researchers and practitioners in fields such as applied mathematics, physics, chemistry, and computational science who are interested in the underlying mechanisms of rare events and their transition processes.

Enhancing clustering blog documents by utilizing author/reader comments
No full textBlogs are a new form of internet phenomenon and a vast ever-increasing information resource. Mining blog files for information is a very new research direction in data mining. Blog files are different from standard web files and may need specialized mining strategies. We propose to include the title, body, and comments of the blog pages in clustering datasets from blog documents. In particular, we argue that the author/reader comments of the blog pages may have more discriminating effect in clustering blog documents. We constructed a word-page matrix by downloading blog pages from a well-known website and experimented a k-means clustering algorithm with different weights assigned to the title, body, and comment parts. Our experimental results show that assigning a larger weight value to the blog comments helps the k-means algorithm produce better clustering solutions. The experimental results confirm our hypothesis that the author/reader comments of the blog files are very useful in discriminating blog files

Service system design research of promoting community school interaction in periurban area : take Jindai elementary school for example
No full textLAUREA MAGISTRALEIl New Jin Dai Primary School, progetto di ricostruzione successivo al grave terremoto
del 12 maggio 2008, è il primo progetto di scuola sostenibile in Cina sostenuto
dal China-USA Center. L'autore ha preso parte al processo di progettazione e di
costruzione della scuola. Tuttavia, dopo due anni di attività, il sistema sostenibile
è completamente fallito sia negli aspetti materiali che immateriali, a causa della
mancanza di sostegno finanziario e di un' istruzione supportata da tecnologie
appropriate. Troppo spesso la comunità locale è totalmente separata dalla scuola, il
che è lontano dagli intenti iniziali di una scuola che sia parte della comunità stessa.
Il legame tra cultura e conoscenza è stato abbattuto, poichè non esiste alcuna
interazione tra la scuola e la comunità locale.
In questa tesi, l'autore presenta studi che forniscono soluzioni preliminari a questa
problematica. La New Jin Dai Primary School ha le sue caratteristiche comuni che
possono essere scelte come rappresentative delle scuole primarie periurbane in Cina.
L'autore ha inizialmente indagato le risorse per la misura della domanda e dell'offerta.
Questa indagine è stata seguita da una ricerca sulla possibilità e sulla fattibilità, che
è stata condotta attraverso casi studio relativi e analisi di tentativi passati. L'autore
costruisce il sistema di servizi sulla base dei dati di cui sopra e sviluppa il prototipo,
che potrebbe essere costituito da piattaforme tangibili ed intangibili che attivino la
cooperazione tra le parti interessate in questo sistema .PSSD aiuta a costruire un
forte legame costituito dalla popolazione locale, dagli estranei e dalla comunità. In
questa circostanza, il sistema PSSD "My New Gold" emerge per fare da estremità
necessaria ad entrambe le parti. Il risultato finale è un nuovo business model che
dovrebbe essere scalabile e in grado di essere promosso in tutte la scuole elementari
rurali in Cina.The New Jin Dai Primary School, the reconstruction project of the severe earthquake
on May 12, 2008, is the first sustainable school project in China supported by China-
US Center. The author used to take part in the design and construction process of the
school. However, after two years of operation, the sustainable system in both tangible
and intangible aspects has completely failed in reality due to the lack of financial
support and education backed by appropriate technologies. Many a time the local
community is totally separated from the school, which is far from the initial intends that
the school is part of the community. The bond between culture and knowledge was
cutted down since no interaction ever exists between the school and local community.
In this paper, the author present studies that provide preliminary solutions to these
problems. The New Jin Dai Primary School has its common features that can be
chosen as the representative of the periurban primary school in China. The author
first investigated the resource of both sides at present to the measure supply and
needs. This was followed by a research on possibility and feasibility , which is
conducted by related case studies and analysis on past attempts. The author builds
the service system based on the data above and develops the prototype, which might
be consist of tangible and intangible platforms that activate the cooperation between
the stakeholders in this system.PSSD helps to build a strong force contributed by local
people, intruder and the community. Under this circumstance, the "My New Gold"
PSSD system is brought out to make the ends need by both sides. The final outcome
is a new business model that should be scalable and capable to bepromoted to all the
rural elementary school in China
Regime complex and energy cooperation in Southeast Asia
No full textDue to the importance of energy to economic growth, ASEAN member states (AMS) have devoted to energy development and regional energy cooperation in recent decades but received limited progress. This thesis is interested in investigating this phenomenon. Upon reflecting on the ASEAN way of cooperation and the trajectory of energy cooperation development, it argues that a patchwork of energy regimes exists and even governs the regional energy cooperation alongside with the ASEAN-led institution. By borrowing the existing wisdom of regime complex, this thesis develops a dynamic holistic framework for complex regime analysis and employs it to examine the current energy cooperation in Southeast Asia (SEA). The author finds that an energy regime complex does exist for SEA energy cooperation as a consequence of fulfilling the multiple interests of AMS. While the regime complex exerts both positive and adverse impact on cooperation, the latter could be overcome by adjusting the regime complex structure so as to facilitate the regional energy cooperation.Master of Science (International Political Economy
