Target Locations

In previous studies we observed a pattern of systematic directional errors when humans pointed to memorized visual target locations in two-dimensional (2-D) space. This directional error was also observed in the initial direction of slow movements toward visual targets or movements to kinesthetically defined targets in 2-D space. In this study we used a perceptual experiment where subjects decide whether an arrow points in the direction of a visual target in 2-D space and observed a systematic distortion in direction discrimination known as the “oblique effect.” More specifically, direction discrimination was better for cardinal directions than for oblique. We then used an equivalent measure of direction discrimination in a task where subjects pointed to memorized visual target locations and showed the presence of a motor oblique effect. We finally modeled the oblique effect in the perceptual and motor task using a quadratic function. The model successfully predicted the observed direction discrimination differences in both tasks and, furthermore, the parameter of the model that was related to the shape of the function was not different between the motor and the perceptual tasks. We conclude that a similarly distorted representation of target direction is present for memorized pointing movements and perceptual direction discrimination.

This study researched whether pertaining to a global strategic alliance brought significant benefits to the ‘bottom line’ of allied airlines. The study used two groups: a group of airlines which had joined one of three global alliances against a control group of airlines which had not joined any alliances. The research compared the net return of those two groups before and after airlines joined their alliances (or equivalent measure), as well as their relative net performance both in the short-term and in a longer term. Results showed a sensible deterioration in net profitability for the alliance group and a perceptible improvement in net profitability for the nonalliance group. The latter also differed from the former in having a positive relative net performance in the short-term.

From 2021, an increasing percentage of the carbon emission growth in international air transport will be subject to offsetting under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). Presently, it is still unclear if, and how, the existing EU emissions trading scheme (ETS) for aviation will continue. We assess the environmental impacts of different options (not) to continue with the EU ETS for aviation alongside CORSIA, and also discuss resulting monitoring, reporting, and verification (MRV) requirements. Our results indicate that any form of continuation of the EU ETS would have positive environmental effects especially in the early 2020s, when the coverage and environmental impact of CORSIA, which only tackles any post-2020 emission growth in international aviation, will still be low. If, moreover, a certain failure of CORSIA Certified Emission Reductions (CERs) to actually achieve emission reduction elsewhere is assumed, the environmental net benefit of CORSIA will be even lower. From both the policy and economic perspectives, these aspects may further strengthen the need to continue with the EU ETS for aviation. Possible options are to maintain the EU ETS in operation for domestic flights only, as a complement to CORSIA, or to keep it alive even for international flights within the European Economic Area (EEA), replacing CORSIA there as an equivalent measure. Another option to increase the environmental effectiveness of CORSIA, at least to some extent, could be to voluntarily extend it to domestic EEA flights. Administrative-wise, the CORSIA MRV system could be applied to a continued EU ETS to reduce transaction costs and to assure globally similar or even identical MRV standards, e.g., with regard to exemptions and eligible fuel monitoring methods.

Abstract This work proposes a sampling inspection framework for point measurement non-destructive testing of pipelines to improve its time and cost efficiencies. Remaining pipe wall thickness data from limited dense inspection are modelled with spatial statistics approaches. The spatial dependence in the available data and some subjective requirements provide a reference for selecting a most efficient sampling inspection scheme. With the learned model and the selected sampling scheme, the effort of inspecting the residual part of the same pipeline or cohort will be significantly reduced from dense inspection to sampling inspection, and the full information can be reconstructed from samples while maintaining a reasonable accuracy. The recovered thickness map can be used as an equivalent measure to the dense inspection for subsequent structural analysis for failure risk estimation or remaining life assessment.

Pitch perturbation is a measure of the cycle-to-cycle variation in vocal fold vibration. Perturbation can be assessed by means of electroglottographic or acoustic signals. The purpose of this study was to determine if these two analysis techniques are equivalent measures. The Laryngograph, an electroglottograph, and the Visi-Pitch, an acoustic analyzer, were used to measure pitch perturbation in 80 dysphonic subjects. Both instruments use Koike's formula to calculate relative average perturbation. While intrasubject variability appeared erratic, statistical analysis of intersubject data indicated that the two instruments provided an equivalent measure of pitch perturbation.

This paper aims at determining the measure of Q under necessary and sufficient conditions. The measure is an equivalent measure for identifying the given P such that the process with respect to P is the deflator locally martingale. The martingale and locally martingale measures will coincide for the deflator process discrete time. We define s-viable, s-price system, and no locally free lunch in ordered Banach algebra and identify that the s-price system C,π is s-viable if and only a character functional ψC≤π exists. We further demonstrate that no locally free lunch is a necessary and sufficient condition for the equivalent martingale measure Q to exist for the deflator process and the subcharacter ϕ∈Γ such that φC=π. This paper proves the existence of more than one condition and that all conditions are equivalent.
