Resolvent estimates for elliptic quadratic differential operators
2011
Sharp resolvent bounds for non-selfadjoint semiclassical elliptic quadratic differential operators are established, in the interior of the range of the associated quadratic symbol.
Applications of Microlocal Analysis in Inverse Problems
2020
This note reviews certain classical applications of microlocal analysis in inverse problems. The text is based on lecture notes for a postgraduate level minicourse on applications of microlocal analysis in inverse problems, given in Helsinki and Shanghai in June 2019.
Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe
2021
International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…
"Peace is a process" : local narratives of peace and the conflict transformation discourse in South Sudan
2017
Tutkimukseni tavoitteena on tarkastella eteläsudanilaisten kansalaisjärjestötoimijoiden näkemyksiä rauhasta itsenäistymisen jälkeisessä Etelä-Sudanissa. Tutkimuksen tehtävänä on selvittää, kuinka ”conflict transformation” ajattelu on vaikuttanut paikallisten rauhan narratiivien muodostumiseen ja tämän analyysin kautta pohtia paikallisen ja kansainvälisten toimijoiden suhdetta Etelä-Sudanin rauhanrakentamisessa. Aineistona tutkimuksessa toimii Crisis Management Initiativen (CMI) keräämä haastatteluaineisto eteläsudanilaisten nuorisojärjestötoimijoiden parissa. Kriittisen narratiivisen analyysin kautta tutkimus pyrkii tuomaan esiin paikallisten näkemysten ja kansainvälisten rauhanrakennusdisk…
Palermo reciclica. Scenari del riciclo per aree, infrastrutture e paesaggi a fine ciclo
2021
Il saggio affronta il tema del riciclo urbano attraverso la mappatura e l'analisi di fenomeni di dismissione e sotto-utilizzo presenti nella città di Palermo. Il tema del riciclo si offre a una città come Palermo come potenziale strumento dirompente di trasformazione. La mappatura e la definizione della tassonomia degli spazi da riconvertire per conoscere le tipologie di offerta potenziale è considerato il primo importante passo a cui affiancare la formulazione delle regole per l’accesso e la condivisione degli spazi, nonché possibili strategie e politiche pubbliche per generare nuove funzioni o consolidare e rinnovare pratiche d’uso già avviate.
Integración y transformación económica en África: potencial y limitaciones del Área de Libre Comercio Continental Africana
2021
In March 2018, the African Union gave way to the establishment of the African Continental Free Trade Area, the largest area of economic integration in the world by number of countries involved. As of June 2020, 54 out of 55 African Union member countries have already signed the agreement, thus showing an almost complete unanimity on this topic. AfCFTA comes up when industrialisation strategies and economic transformation in Africa seem to have taken over orthodox structural adjustment and post-adjustment approaches. AfCFTA aims to increase the scarce intra-African trade, boost economic transformation, create the regional value chains and help African firms to join the global value chains. I…
Cautionary note on the two-step transformation to normality
2020
Templeton and Burney (2017) proposed a two-step normality transformation as a remedy for non-normally distributed data, which are commonly found in AIS research. We argue that, rather than transforming the data toward normality, researchers should first seek to analyze and understand the sources of non-normality. Using simulated datasets, we demonstrate three sources of non-normality and their consequences for regression estimation. We then demonstrate that the two-step transformation cannot solve any of these problems and that each source of non-normality can be handled with alternative, existing techniques. We further present two empirical examples to demonstrate these issues with real da…
Active disturbance rejection control of linear induction motor
2017
This paper proposes the theoretical framework and the experimental application of the active disturbance rejection control to linear induction motors. Such a nonlinear control (ADRC) technique can be viewed as a particular kind of input-output linearization control, where the nonlinear transformation of the state is not computed by means of the model, but it is estimated online. Such an approach permits to cope with unmodelling dynamics, as well as uncertainty in the knowledge of the model parameters and exogenous disturbances. The effectiveness of the proposed ADRC control law has been verified both by numerical simulations and experimentally on a suitably developed test setup. Moreover, t…
Religijne budowanie pokoju (religious peacebuilding): rola religii w rozwiązywaniu konfliktów
2016
In relation to the evolving nature of armed conflicts, the so-called „soft aspects” of peacebuilding have been gaining significance in the last few decades. The hitherto dominant perspective based on solid features of structural and institutional development is being extended in the direction of appreciation of one’s viewpoint, manner of perception by individuals and interpersonal relations. In this approach, subjects remaining in conflict (perceived both individually and as a group) are regarded as means and goals that make achievement of permanent peace possible. It is assumed that efficient peacebuilding is only possible through understanding the way of thinking and feeling by conflictin…
CO-Evolution Between CCC-Driven Cash Flow Management and Transformation of R&D : Amazon’S Endeavor
2019
Amazon became the world R&D leader in 2017 by rapidly increasing R&D investment. The company’s extremely large amount of R&D funds is the result of an ample free cash flow generated by sophisticated cash conversion cycle (CCC) management. Increased R&D induced business advancement and lean cost structure construction leading to further increase in cash flow which has stimulated interaction between vendors, customers, and Amazon via the Amazon marketplace. Activated interaction accelerated CCC advancement, a subsequent free cash flow increase, and user-driven innovation, thus accelerated the transformation of routine and periodic alteration activities into significant improvement simultaneou…
