Vibration of Bundled Conductors Following Ice Shedding
No full textThe dynamic behavior of bundled conductors following ice shedding from one subconductor is examined numerically using the finite-element method. An existing model of ice shedding from a single conductor is improved by developing a model of spacers which connect subconductors in the span. The resulting system makes it possible to simulate vibrations following ice shedding from one span of an overhead transmission line with twin, triple, or quad bundles. Vibration characteristics are evaluated as the following parameters are varied: thickness of shed ice, distance between adjacent spacers, and number of subconductors in the bundle. Simulation results will provide information on how the amplitude of vibration and the transient dynamic forces change with the application of spacers. The maximum jump height of the ice-shedding cable, the maximum drop of the loaded cable, and the maximum cable tension are approximated as power functions of ice thickness and the distance between adjacent spacers
Scanning tunneling microscopy and spectroscopy studies of graphene
No full textIn the two-dimensional (2D) lattice of graphene, consisting of carbon atoms arranged in a honeycomb lattice, the charge carriers are described by a Dirac-Weyl Hamiltonian. Seeking to understand their unique nature, this thesis presents results of scanning tunneling microscopy (STM) and spectroscopy (STS) experiments at low temperatures and in magnetic fi eld. These techniques give access, down to atomic scales, to structural information as well as to the electronic properties of graphene. The main findings include the observation of quantized Landau levels (LL) in the presence of magnetic field, their dependence on carrier density and e ffects of charged impurities and other disorder on the LL spectrum. Twisting graphene layers away from the equilibrium Bernal stacking leads to the formation of Moir e patterns that signi ficantly alter the electronic properties of graphene stacks. The second part of the thesis discusses the eff ects of such rotations on the electronic properties as a function of twist angle.Ph. D.Includes bibliographical referencesby Adina Luican-Maye

Approaches to Monitoring and Evaluation Strategy Development
No full textThe Handbook aims to provide decision-makers with a comprehensive NBS impact assessment framework, and a robust set of indicators and methodologies to assess impacts of nature-based solutions across 12 societal challenge areas: Climate Resilience; Water Management; Natural and Climate Hazards; Green Space Management; Biodiversity; Air Quality; Place Regeneration; Knowledge and Social Capacity Building for Sustainable Urban Transformation; Participatory Planning and Governance; Social Justice and Social Cohesion; Health and Well-being; New Economic Opportunities and Green Jobs. Indicators have been developed collaboratively by representatives of 17 individual EU-funded NBS projects and collaborating institutions such as the EEA and JRC, as part of the European Taskforce for NBS Impact Assessment, with the four-fold objective of: serving as a reference for relevant EU policies and activities; orient urban practitioners in developing robust impact evaluation frameworks for nature-based solutions at different scales; expand upon the pioneering work of the EKLIPSE framework by providing a comprehensive set of indicators and methodologies; and build the European evidence base regarding NBS impacts. They reflect the state of the art in current scientific research on impacts of nature-based solutions and valid and standardized methods of assessment, as well as the state of play in urban implementation of evaluation frameworks.Heritage & Technolog

Towards a theory of denominals in English and Romanian
No full textThe aim of this thesis is two-fold. On the one hand, it has a descriptive purpose, as it strives to capture the differences between denominal verbs in English and Romanian from a descriptive point of view by looking at significant data: a database of English denominal verbs created by Clark & Clark (1979), a database of Romanian denominal verbs created by the author of this thesis on the basis of a bilingual dictionary (Halvorsen 2007). An essential difference is the fact that, while English denominals have the same form as the bare noun they derive from (dance-dance, butter-butter, corral-corral, hammer-hammer), Romanian denominals have a different form: while the noun has the form dans, the verb is dansa, with an additional suffix indicating the declension. Moreover, denominals are very productive in English, whereas they are not in Romanian: there is no correspondent for the verb to shelve, for instance; instead, Romanian uses the periphrastic a pune pe raft ‘to put on shelf’.
On the other hand, the thesis has a theoretical purpose. It aims at clarifying the notion of denominal verb, at presenting the analyses that have been proposed as accounts of denominals in the literature (Hale & Keyser 1998, 2002, Mateu 200, 2002, Ramchand 2008 a.o.), but it also aims at putting forth a novel approach starting from the nanosyntactic framework (Starke 2001, 2009, Caha 2009, Pancheva 2011), according to which lexical items may target phrasal nodes. I have embraced Ramchand’s (2008) analysis of verbs along the tripartition InitiationP, ProcessP, resultP, together with Svenonius’s (2007) and Pantcheva’s (2011) nanosyntactic decomposition of spatial prepositions (as RouteP>SourceP>GoalP>PlaceP>N). Thus, an item such as the denominal corral (the horses), paraphrased as ‘put the horses in the corral’ may be argued to spell out InitP, ProcP, GoalP, PlaceP, N, an item such as the verb dance, paraphrased as ‘do a dance’ may be argued to spell out InitP, ProcP, N, whereas pseudoagentive verbs like spy spell out InitP, ProcP, PP, N, as also indicated by the paraphrase ‘act like a spy’. As for instrument verbs such as hammer, it may be argued they spell out InitP, ProcP, PP, N, if one thinks of a paraphrase such as ‘hit with a hammer’, or even InitP, ProcP, N, if one embraces a ‘use a hammer’ paraphrase. A similar proposal is adopted for Romanian denominals. In the various analyses I provided throughout the thesis, I sometimes tried to make use of silent items such as the silent prepositions IN, ON or the silent preposition WITH. Such silent items feed the structure with meaning which cannot be otherwise captured by the projections, given that they are not fine-grained enough. Moreover, interestingly, the lexical item lexicalizing the extremity (initP) will never be used in the actual language as a spell out of Proc or Goal or Place. Such a gap can be argued to be verb-specific. If, on the other hand, one postulates silent items, the absence of a preposition corral or a preposition hammer could be explained by the presence of a silent item IN or WITH lexicalizing the GoalP or the PP.
A Phrasal Spell-Out account is a viable option for explaining the formation of denominals. However, it has its problems and limits. If one take an example such as Linda danced into the room, embacing the nanosyntax way of storing items as trees in the lexicon would lead to the conclusion that the item dance into has to be stored in the lexicon, just as all the other manner verbs in English combining with a GoalP. This would result in a burdensome lexicon, which is undesirable and can be avoided if one adopts a view where syntax exists as a module per se, distinct from the lexicon.
All in all, the thesis discusses a novel approach to denominals, applying it to verbs in English and Romanian, and trying to see to what extent such an approach can capture their formation and behaviour
Virtual reality as a complementary therapy to sexual addiction treatment
No full textpeer reviewedVirtual reality has gained traction as a research, education and treatment tool. Virtual reality is a system that immerses people in virtual worlds and improves clinicians’ traditional treatments for addictive disorders, eating disorders, phobias, and stroke rehabilitation. Sex addiction is a dysregulation of sexual desire, characterized by excessive sexual behavior (between 5-15 sexual activities/day, for more than 6 months, after the age of 15). Hypersexuality highlights disturbances in human sexual desire, motivation, and behavior systems. Virtual reality worlds were initially designed to treat smokers and alcoholics, and are now programmed for drug users and other kind of addictions. In this article we present different characteristics of sex addiction and possible treatments, including the virtual exposure treatment
ABOUT OTHER KIND OF PRODUCTIVITY AND GROWTH (HOMO-SAPIENS TO HOMO-OECONOMICUS)
No full textPart of a larger research, this paper ranges among the matter of ideas confrontation concerning the causes of the economic crises and those keys to be passed. Paper aims at finding and praising the defining elements of our economy, in the purpose of better understanding the nowadays crisis, and at presenting certain conceptually different approaches. In this purpose, analytical presentations are focussed on the specific realities of the economic life that are in position in the last centuries, which are considered to be favouring the arriving to the critical states in the last years and to be promoting those maintaining, or which allow explaining certain effects and tendencies. The approach is made from the angle of the nature of the productivity that is had in view and highlighted in the market regulating mechanisms, and of the due growth. The paper is grounded on important analysis on the matter (including anterior researches of the author), but their dimensions does not allow their presentation in the abstract. Analysis starts from interpreting the very nowadays crisis, from different sites concerning the core (general) causes, by correlating with certain features of the industrialized consuming society. More recent references are made in the literature on the matter. Modern western economy is defined from the angle of focussing on material-quantitative productivity and growth. Analysis tries to explain certain effects concerning this kind of focus. Interesting effects and tendencies are noticed, that miss to the traditional approaches. Further on an opposed theoretic model is discussed. This is built and developed inside the service economy (on the case of two conceptually similar approaches, came from two different sources of economic thought in the field; original contributions of the author are involved). Adequately to the knowledge society, this last one is considered more favourable for homo sapiens, at least once the visible effects of the last two hundred years model are revealed, which are dominated by homo oeconomicus. This reference model being set up, a short foray is intuitively made in the perspectives of humanity on long run and on very long time, in the supposed maintain of the present economic model. In all those presentations and analyses, connections are made with other papers on the matter, in the purpose of more profound study. The conclusions concern the practical possibility of the model opposed to the industrialist economic crisis. The details highlighted from the analysis of the conceptual comparison between models and prospections bring, in the final, at proposing solutions, grounded on fundamental requirements on the line of humanityâ€(tm)s values, with didactic addressing to the young generation. The elements of contribution of the author are underlined in the presented matter.productivity, modern growth, economic crisis, knowledge society, service economy
