Mitigating the Climate Change Impacts of Aviation through Behavioural Change

2020

Aviation plays a crucial role for economic development and social welfare, but at the same time it also significantly contributes to climate change. Therefore, if the industry wants to follow the same growth path as it has in the past, it will need to mitigate its environmental impacts more seriously or it may otherwise face regulatory restrictions. The current literature has discussed five mitigation strategies. These are technological changes, market-based changes, operational changes, regulatory changes and behavioural changes. While several authors have regarded behavioural changes as the measure with the greatest mitigation potential, it is also the measure that has received far less a…

Modeling the Probability of Informed Trading in the European Carbon Market

2012

We provide evidence of informed trading in the European carbon market. We adapt Easley et al.’s (1996) PIN methodology to the particularities of this market by isolating the trading activity on the two carbon offsets: European Union Allowances (EUAs) and Certified Emission Reductions (CERs). We find that the PIN regularly increases before the publication of the yearly verified-emission reports. CERs exhibit lower average PIN than EUAs. While the PIN of CERs has increased over time, together with its share in total trading activity, EUAs’ PIN has remained pretty stable. Our findings suggest that CERs must not be avoided in any decision or analysis made by researchers, regulators or traders i…

Generation of Pair Coherent States in Two-dimensional Trapped Ion

2001

We consider a two-dimensional (2D) trapped ion model in which two laser beams drive the corresponding vibrational motions and are carrier resonant with the two-level of the ion. Due to the coherent superposition of two sub-Rabi oscillations involved in the bimodal vibrations, the Rabi frequency degeneration and offset may occur in this model. This provides the possibility of generating the pair coherent state in the 2D trapped ion.

Noise traders and smart money: Evidence from online searches

2019

International audience; Traditional finance theory considers that the impact of noise traders' attention on asset prices is offset by attention from smart investors. This paper uses online search data to study the influence of noise traders and smart investors on stock returns and volatility. Adopting an original approach, we construct a proxy for smart investor attention based on investors' online search behavior provided by Wikipedia Page Traffic. We combine this new measure with a standard measure of noise traders' attention as proxied by Google Search Volume Index. We show for a sample of 87 French firms over the period 2008–2018 that only noise traders' attention influences stock retur…

Expanding education through user charges : what can be achieved in Malawi and other LDCs ?

1986

International audience; Two features mark the education sector in many LDCs today: first, education is publicly provided; and second. governments are faced with severe financial constraints. As a result, enrollmrnts are confined to low Ievels, and there is excess demand. To mitigate these adverse outcomes, we consider user charges as a means to mobilize additional resources for education. Under the circumstances that characterize most LDCs. we show that (i) families are willing to pay for education: (ii) the resources collected through user charges could finance a sizable expansion of education; and (iii) scholarships can offset the equity effects of user charges.

Conservative swept volume boundary approximation

2010

We present a novel technique for approximating the boundary of a swept volume. The generator given by an input triangle mesh is rendered under all rigid transformations of a discrete trajectory. We use a special shader program that creates offset geometry of each triangle on the fly, thus guaranteeing a conservative rasterization and correct depth values. Utilizing rasterization mechanisms and the depth buffer we then get a conservative voxelization of the swept volume (SV) and can extract a triangle mesh from its surface. This mesh is simplified maintaining conservativeness as well as an error bound measured in terms of the one-sided Hausdorff distance. For this we introduce a new techniqu…

Biomechanical analysis of the humeral tray positioning in reverse shoulder arthroplasty design

2017

Despite the widespread use of reverse total shoulder arthroplasty, the fundamental effects of implant configuration on certain biomechanical outcomes have not been completely elucidated especially for the most innovative prostheses. Aim of this work is to investigate the behaviour of a new reverse shoulder prosthesis, characterized by a humeral tray with a variable offset, designed to increase the range of motion and to reduce the impingement. The purposes of this study were to evaluate the effect of reverse shoulder implant design parameters on the deltoid muscle forces, required to produce abduction, and on the shoulder range of motion, in order to provide a more systematic understanding …

A novel current-based approach for very low variation detection of resistive sensors in wheatstone bridge configuration

Design, fabrication, and analysis of a spin-valve based current sensor

2004

Abstract In this work, we suggest a novel current sensor design, based on spin valve technology, with a full Wheatstone bridge configuration. The principal characteristic is that the four magnetoresistance sensing elements, fully active, are deposited and patterned at the same time. This way, differences among them should be insignificant, so improving voltage offset and drift temperature parameters. The complete IC fabrication process involves only three lithography steps, making the process cheaper and faster. In order to get a balanced bridge, the measured current must be properly driven, by means of an auxiliary PCB. Some prototypes, with different input impedances, have been fabricated…
