The main purpose of this thesis is to describe different numerical methods for solving the time-dependent Schr¨odinger equation. We introduce and describe two different basis representations (spectral and pseudospectral). These basis representations are then used in the different methods we take up for discussion. We consider methods in which the Hamiltonian is constructed in a spectral basis and
VIX, published by the Chicago Board Options Exchange, is a well known implied volatility estimator. In this paper we assess its capability to be used as a sentiment indicator, and to give signals for a short term investment strategy. It will be proved and discussed how VIX-based strategies – also known as “Contrarian” strategies – can be effective as they lead to higher returns than the market. We
In 1996, Robert A. Haugen and Nardin L. Baker published a study where they had made a multi-factor model based on micro-variables on the American stock market between 1979 and 1993. In testing the model on the examined period they made an average annual return of 30,9 percent. They also tested the model on several other markets around the world with similar results. This study is a somewhat simple
The precise valuation and correct assessment of the value of imported goods should be preceded by determining the value of imported goods for Customs purposes. The provisions regulating the Customs valuation are overlapped and complicated; the reason which prompted the Author, through this paper, to eliminate this overlaps and simplify the complexity, using a new approach represented by reclassify
A derivation for a polarized CCFM evolution equation which is suitable to describe the scaling behavior of the unintegrated polarized gluon density is given. We discuss the properties of this polarized CCFM equation and compare it to the standard CCFM equation in the unpolarized case.
Indications of what the tour-operating sector considers to be 'good practice' can be drawn from voluntary initiatives such as existing eco-labels and codes of conduct. However, practical implementation of such guidance varies greatly from one tour operator to another, depending on different types of factors, such as size, financial capacity, corporate structure, operational location, organizationa
This thesis deals with driving forces for CSR reporting in China. More and more international companies have published their CSR reports under the concern of sustainable development. Chinese companies are facing the environmental and social challenges in China today. CSR reporting has been taken as a sustainable development strategy by the Chinese Central Government and the pioneering Chinese comp
A model for the interpretation of nystagmus is worked out. A lesion in the vestibular system may appear as alteration in velocity of slow viz. fast phase of nystagmus, disconjugation of the nystagmus or as dysrhythmic nystagmus. The visual system, viz. the cortical and subcortical optokinetic nystagmus seems to provide the eye-head coordinates and retical error velocity to calibrate or cancel the
In December 1998 the FRN - The Swedish Council for Planning and Coordination of Research - decided to fund a new injector and storage ring for the MAX-laboratory. The system will consist of a 50-MeV linac, a 600-MeV booster synchrotron, and a 600-MeV storage ring for VUV undulator beamlines. The system will replace an old 100-MeV racetrack microtron and will inject the two existing storage rings:
This chapter aims to provide practical evidence-based guidance in the use of generative artificial intelligence (GenAI) for the design and management of authentic assessment tasks and provide a grounding for institutional policy conversations so that decisions can be influenced in a constructive learner-centric way. Drawing on the foundational principles of assessment and feedback, we critically e
Radon gas is the largest source of public exposure to naturally occurring radioactivity. However, radon is also a useful tracer for understanding atmospheric processes, assessing the accuracy of chemical transport models, and enabling integrated emissions estimates of greenhouse gases. A sound metrological system for low level atmospheric radon observations is therefore needed for the benefit of t
To meet climate targets, expanding Populus spp. tree cultivation is proposed as a potential biomass feedstock, especially on agricultural land that does not come into conflict with food production. However, biomass potential assessments typically overlook landowners' perspectives, risking a gap between theoretical potentials and realisation. Here, we test empirical consequences of two hypotheses b
The evolution of whole-body endothermy occurred independently in dinosaurs and mammals and was associated with some of the most significant neurocognitive shifts in life's history. These included a 20-fold increase in neurons and the evolution of new brain structures, supporting similar functions in both lineages. We propose the endothermic brain hypothesis, which holds that elaborations in endoth
We present a summary of the commissioning and performance of the vacuum system of a 500-MeV booster synchrotron recently built at LNLS as part of a new injector for the LNLS light source. The main vacuum parameters of the synchrotron are pressure below 5×10-7Pa (lifetime of 1-2 hours), no in-situ baking, no cooling system, and a short recovery time after ventilation. All parts of the system are ma
This concert featured the world premiere of new music for serpent from the composers Orlando Bass, Henrik Denerin, Athena Corcoran-Tadd, and Jesse Ronneau (the latter also with live electronics). The concert opened with a performance of a 17th-century work from Girolamo Frescobaldi with Orlando Bass on harpsichord. There was also a visual presentation, illustrating the history of the serpent and b
