Multiple scale methods

Many physical problems involve more than one temporal or spatial scale. One important example is the boundary layer problem, where we recognize one fast and one slow scale. In that case the two scales are separated, in the sense that fast scale only affects the boundary layer, while the outer solution is governed by the slow scale alone. In fact, the slow scale is also present in the boundary layer, but influences only the higher order approximations that we do not address in Mek 3100. In boundary layer theory we exploit the dominance of the fast scale in the boundary layer to find an approximate inner solution. The inner fast solution and the outer slow solution is then matched to provide a complete approximation. In other problems both the slow and fast scales may present everywhere. The scales may have different physical origins, such as in the first example below where a fast oscillation is subjected to a slow damping. Another example is propagation of short waves in a slowly varying medium, where the fast scale corresponds to the wavelength while the slow scale is associated with the variation of the medium. In other cases the slow scale may be due to gentle nonlinear effects that modify periods or rates of change for the system. Subsequently we will retrieve the periodic solution of a nonlinear pendulum, that has previously been found by Poincare-Lindsted’s method, by a two scale perturbation expansion. In a multiple scale technique we introduce several time, or space, variables, that are scaled differently and regarded as being independent. As for other perturbation methods, this one is best outlined through examples. For linear problems we have a particularly powerful and simple version of multiple scale expansions called the WKB(J) method. This is a topic in other courses and will not be described herein.

THE AERO-CAVE EXTENSION FOR MIXED REALITY COLLABORATION

Mixed reality environments, especially CAVES, are still very much restricted towards vision and sound as means of communication between dislocated engineers. For future applications of mixed reality collaboration caves in engineering, it is important to integrate more physical phenomena into the collaboration session. This paper will present an "Aero-Cave", the extension of a low cost cave, developed in a student project, with aerodynamics. It will be argued, that this extension might be helpful for some engineering design and maintenance tasks.
Visual Motion Observer-based Pose Control via Image Space Navigation Function

This paper investigates passivity-based visual feedback control via an image space navigation function. Firstly, a brief summary of a visual motion observer is given. Next, a visual motion error system is reconstructed in order to apply to timevarying desired motion. Then, visual motion observer-based pose control for a 3-D visual feedback system is proposed. Moreover, a path planner to be appropriate for the visual motion error system is designed through the image space navigation function to keep all features into a camera field of view. Finally, simulation results are shown in order to confirm the proposed method.

The Paradox of Insider Information and Moral Hazard ∗

This article investigates the paradox of insider information and moral hazard as it pertains to managerial compensation. Managers are paid to organize human resources under their command in creative ways to extract more value to the firm. This paper shows that there are indeed good empirical grounds for taking this source of hidden interest( Insider Information) quite seriously as a motivation for changes in managerial portfolios with respect to their own firms.We provide a theoretical framework that explains how these conflicting goals might be resolve within equilibrium.
Uncertainty and complexity in cloud microphysics

Klein and Jakob (1999) showed that high clouds in frontal systems of ECMWF forecasts are more sensitive to the parameterization of ice microphysical processes than to other processes and parameters. Especially the gravitational settling controls the amount of high clouds and their ice water content. A decade later Waliser et al. (2009) highlight that different climate and NWP models show a large range of simulated ice water paths which shows that the uncertainties regarding ice clouds are still unresolved. This problem is also a major motivation for the Cloudsat mission (Stephens et al., 2002).
On the construction of the Feynman path integral for the Dirac equation

The Feynman path integral for the Dirac equation is determined mathematically, in the form of the sum-over-histories, satisfying the superposition principle. That is, it is given by the $\langle(sum$” of the probability amplitudes with a common weight, over all possible paths that go in any direction at any speed forward and backward in time. It has been expected by Feynman himself for a long time that the Feynman path integral for the Dirac equation is represented in this form. \S
Short-and Long-term Toxicity of Cadmium and Polyaromatic Hydrocarbons on Zebra Mussel Dreissena polymorpha ( Pallas , 1771 ) ( Bivalvia : Dreissenidae )

This study was designed to examine the possible negative effects, which cadmium (Cd) and polyaromatic hydrocarbons (PAHs) could have on the lysosomal membrane stability in haemocytes of the invasive mollusk zebra mussel (Dreissena polymorpha) by applying the neutral red retention assay (NRRA). The mussels were exposed to different concentrations of Cd and PAHs in laboratory conditions for 96 hours (acute exposure) and 31 days (chronic exposure). These are considered as priority substances in surface waters according to Directive 2008/105/EC. We found lysosomal membrane destabilisation in all mussels treated with Cd and PAHs, including concentrations, which were lower than the allowable ones. In addition, we determined a trend of lower retention time in the mussels treated with Cd as compared to the ones treated with PAHs, although these differences were not significant (p>0.05). Our results confirmed that the neutral red retention assay could be used as a cheap, fast and reliable biomarker for Cd and PAHs effects on freshwater mollusks and that zebra mussel could be suggested as a freshwater bioindicator for water contamination. However, further studies are required in order to better understand the negative effects of Cd and PAHs on this bivalve species.
“CRISIS AND CRISIS FOR WHOM?”

This Master thesis aims to conduct a critical discourse analysis of how Swedish and British editorials covered the so-called "refugee crisis" during the autumn of 2015, specifically from Aug 1 to Dec 31 st. The overall aim is to investigate the discursive construction of the crisis, which entails investigating how the editorials framed the “crisis” and in what way it is a crisis: how the term was conceptualised. By making a comparison between two countries, the aim is to get a better understanding of the so-called crisis and the discursive construction surrounding it in various societal contexts. Two newspapers were picked in both of the countries from the UK was The Daily Telegraph, and The Guardian picked and in Sweden was Dagens Nyheter, and Svenska Dagbladet picked. Two theories was applied Framing theory and the securitization theory. The analysis and results showed that the editorials framed the crisis in accordance to the literature that was reviewed. More specifically, in both countries the crisis was described as being an effect of the excessive number of refugees that entered the European borders. The framing focused on the crisis from a European perspective where most of the themes did not consider the perspective of the refugees. Moreover, the results show that the refugee crisis was in fact securitized due to the editorial coverage of the crisis. Furthermore, as a consequence of concluding the aim of this paper the result of the study will hopefully be used as a stepping stone for further research.
Intonation and discour

This paper describes intonational cues to discourse structure, and the role that intonation plays in spoken discourse processing. We begin by discussing two main structures in discourse that one must consider when doing research on discourse processing: segmentation and information status. We then review a number of key studies from the phonetics literature which have investigated the intonational marking of these structures. Next, we discuss in detail the psycholinguistic research to date which has examined the role that intonation can play in facilitating or inhibiting the processing of discourse in English and other related languages. We conclude by outlining directions for future research in the area of intonation-discourse processing.
Plasma biomarker discovery for early chronic kidney disease diagnosis based on chemometric approaches using LC-QTOF targeted metabolomics data

Chronic kidney disease (CKD) is a progressive pathological condition in which renal function deteriorates in time. The first diagnosis of CKD is often carried out in general care attention by general practitioners by means of serum creatinine (CNN) levels. However, it lacks sensitivity and thus, there is a need for new robust biomarkers to allow the detection of kidney damage particularly in early stages. Multivariate data analysis of plasma concentrations obtained from LC-QTOF targeted metabolomics method may reveal metabolites suspicious of being either up-regulated or down-regulated from urea cycle, arginine methylation and arginine-creatine metabolic pathways in CKD pediatrics and controls. The results show that citrulline (CIT), symmetric dimethylarginine (SDMA) and S-adenosylmethionine (SAM) are interesting biomarkers to support diagnosis by CNN: early CKD samples and controls were classified with an increase in classification accuracy of 18% when using these 4 metabolites compared to CNN alone. These metabolites together allow classification of the samples into a definite stage of the disease with an accuracy of 74%, being the 90% of the misclassifications one level above or below the CKD stage set by the nephrologists. Finally, sex-related, age-related and treatment-related effects were studied, to evaluate whether changes in metabolite concentration could be attributable to these factors, and to correct them in case a new equation is developed with these potential biomarkers for the diagnosis and monitoring of

A SECURE AND DYNAMIC MULTI-KEYWORD RANKED SEARCH SCHEME OVER ENCRYPTED CLOUD DATA

with the advantage of storage as a service many enterprises are moving their valuable data to the cloud, since it costs less, easily scalable and can be accessed from anywhere any time. The trust between cloud user and provider is paramount. We use security as a parameter to establish trust. Cryptography is one way of establishing trust. Searchable encryption is a cryptographic method to provide security. In literature many researchers have been working on developing efficient searchable encryption schemes. In this paper we explore some of the effective cryptographic techniques based on data structures like CRSA and B-Tree to enhance the level of security, hence trust. We tried to implement the search on encrypted data using Azure cloud platform.
Explaining the Success of User-Centered Design-An Empirical Study across German B 2 C Firms

I revisit Fazzari et al. (1988) seminal paper on the investment-cash flow sensitivity as a measure of financing constraints and augment their approach with the findings from recent papers. I find that the investment-cash flow sensitivity has decreased and mostly disappeared over time, in line with recent literature. This finding is robust to alternative specifications and a number of robustness checks. I contribute to the literature by explicitly analyzing the strict-exogeneity assumption of the fixed-effects and first-differences estimators in empirical practice. In this setting, strict exogeneity does not hold and the violation can cause substantial inconsistencies.

November 2018 UP PADOVA Native and Immigrant Parents ’ Involvement in School-Related Activities in France and Italy

Sociologists of education have devoted relatively little attention to examining whether, and to what extent, parents interact with schools and teachers, on what issues and whether such engagement varies according to parents’ native or immigrant status. Yet this topic deserves to be explored, since students’ academic success is closely associated with the degree of parental participation in school-related activities. Data drawn from the 2015 edition of PISA (Programme for International Student Assessment), and more specifically from its parent questionnaire, show that immigrant-origin parents of 15-yearold students are more likely (with respect to native parents) to face a set of barriers to parental involvement with teachers and schools, in both France and Italy. Parental involvement in a set of school-related activities is explored via multivariate analyses in order to investigate the role of native/immigrant status, its interaction with parents’ socio-economic-cultural status, and the effects of a host of other variables relating to ascriptive characteristics, parentchild relationships, students school-based behaviour and parental perception of school contexts. Findings are heterogeneous in nature: they point to stronger parental involvement in Italy than in France and highlight the importance of teacherversus parent-initiated activities, as well as the varying role of socioeconomic-cultural status.
Melatonin in perimenopausal and postmenopausal women : associations with mood , 1 sleep , climacteric symptoms and quality of life 2 Running Title : Melatonin in perimenopause and postmenopause 3 4

30 Objective: Melatonin synthesis and secretion are partly modulated by estrogen and 31 progesterone. Changes in melatonin concentrations, possibly related to the menopausal 32 transition, may be associated with climacteric mood, sleep and vasomotor symptoms. The 33 aims of this study were to compare the serum concentrations of melatonin in perimenopausal 34 and postmenopausal women, and to evaluate its influence on mood, sleep, vasomotor 35 symptoms and quality of life. Methods: We analyzed data of 17 perimenopausal (43-51 36 years) and 18 postmenopausal (58-71 years) healthy women who participated in a prospective 37 study. During the study night (21:00-09:00 hr) serum melatonin was sampled at 20-minute 38 (21:00-24:00 hr; 06:00-09:00 hr) and one-hour (24:00-06:00 hr) intervals. Questionnaires 39 were used to assess depression (Beck Depression Inventory, BDI), anxiety (State-Trait 40 Anxiety Inventory, STAI), insomnia and sleepiness (Basic Nordic Sleep Questionnaire, 41 BNSQ), subjective sleep quality, vasomotor symptoms, and the quality of life (EuroQoL). 42 Results: Postmenopausal women had lower nighttime serum melatonin concentrations than 43 perimenopausal women. The duration of melatonin secretion tended to be shorter in 44 postmenopause, while the melatonin peak time did not differ. Mean melatonin concentrations 45 and exposure levels did not correlate with FSH or E2, BMI, BDI, STAI, BNSQ insomnia, 46 BNSQ sleepiness, subjective sleep, climacteric vasomotor score or the quality of life. In 47 perimenopause, the later the melatonin peak, the higher the level of anxiety (p=0.022), and the 48 longer the melatonin secretion, the better the quality of life (p<0.001). Conclusions: 49 Longitudinal research is needed to better understand the possible contributive role of 50 menopause on lower melatonin levels. 51
Isolation and Characterization of Pasteurella multocida from Infected Animals

Haemorrhagic septicaemia is an acute and fatal disease among cattle and buffaloes caused by Pasteurella multocida. The prevalence of this disease is 49% in animals of Pakistan. The present study was undertaken to evaluate the prevalence, multidrug resistance and the molecular heterogeneity within clinical strains of P. multocida collected from different cities of Pakistan. Tissue samples of lung and spleen of dead animals were used for diagnostics. Rapid plate screening test for Hyaluronidase of clinical Isolates showing clear and white zones proved that given isolate is pathogenic. Amongst one hundred and ninety-nine isolates, only one hundred and one isolates were found to be virulent as clinical isolate of P. multocida. Isolates were confirmed through amplification (PCR) of specie–specific and Haemorrhagic septicaemia type B causing test. The primer pair of specie –specific test showed a band of 300bp in all subspecies of P. multocida whereas the primer pair of HS type B causing test showed a band of 460bp in all HS causing serotype of P. multocida. The high prevalence was found only in Karachi. Whole cell and envelope protein profile of the isolates on SDS-PAGE showed presence of common proteins of 55, 43 and 26kDa indicating no molecular heterogeneity among strains. Representative samples of clinical Isolates from nine different cities were tested for antibiotics sensitivity test. Isolates from Karachi, Badin, Taxila and Abbotabad showed resistant against, Ciprofloxacin, Neomycin, Ofloxacin and Norfloxacin. This study concluded that organism was genetically conserved and there is no diversity within the number of samples tested.
Super Altruistic Hedonic Games

Hedonic games are coalition formation games in which agents’ utility depends only on their own coalition. The introduction of Altruistic Hedonic Games increased the expressive potential of Hedonic Games by considering the utility of each of the agent’s friends within the coalition. We introduce Super Altruistic Hedonic Games (SAHGs), in which an agent’s utility may depend on the utility of all other agents in the coalition, weighted according to their distance in the friend-ship graph. We establish the framework for this new model and investigate the complexity of multiple notions of stability. We show that SAHGs generalize Friend-oriented Hedo-nic Games, Enemy-oriented Hedonic Games, and selﬁsh-ﬁrst Altruistic Hedonic Games, inheriting the hardness results of these games as minimum upper complexity bounds. We also give SAHGs that have neither Nash stable nor strictly core stable partitions.
