This paper provides preference foundations for parametric weighting functions under rank-dependent utility. This is achieved by decomposing the independence axiom of expected utility into separate meaningful properties. These conditions allow us to characterize rank-dependent utility with power and exponential weighting functions. Moreover, by allowing probabilistic risk attitudes to vary withi...

This study attempted to evaluate and compare language learning apps and the related traditional books on the same subject. The apps included Murphy’s English Grammar and Cambridge Discovery Readers and the traditional materials were English Grammar in Use and Developing Reading Skills. The study, thus, aimed to do a comparative analysis between traditional ELT materials and the digital versions...

Demands for planetary landing Unmanned exploratory missions to e.g. Mars involve a landing phase, where the spacecraft descends vertically to the planetary surface. In order to minimize the impact during landing a breaking system of parachutes and airbags is employed. This system is uncontrolled and hence not able to adapt to unforeseeable situations. Indeed, landing spacecraft may easily hit a...

In this paper, I shall discuss issues regarding globalization and culture in the context of English language teaching (ELT), with a particular focus on Chinese ELT materials in secondary schools in China. Globalization has a far-reaching impact on the foreign language education industry in China. Chinese learners of English view globalization positively as opportunities for geographical and soc...

The capacity of a runway system represents a bottleneck at many international airports. The current practice at airports is to land approaching aircraft on a first-come, first-served basis. An active rescheduling of aircraft landing times increases runway capacity or reduces delays. The problem of finding an optimal schedule for aircraft landings is referred to as the “aircraft landing problem”...

BACKGROUND Some research studies have investigated the effects of anterior cruciate ligament (ACL) injury prevention programs on knee kinematics during landing tasks; however the results were different among the studies. Even though tibial rotation is usually observed at the time of ACL injury, the effects of training programs for knee kinematics in the horizontal plane have not yet been analyz...

This paper presents a short contribution in air transportation, specifically in scheduling aircraft (plane) landings at Léopol Sédar Senghor (LSS) airport of Dakar. The safety of air navigation of LSS is managed by ASECNA: Agency for Air Navigation Safety in Africa and Madagascar. Scheduling aircraft landing is the problem of deciding a landing time on an appropriate runway for each aircraft in...

The purposes of this study were to assess unilateral and bilateral vertical jump performance characteristics, and to compare the vertical ground reaction force characteristics of the impulse and landing phase of a vertical jump between the dominant and non-dominant leg in soccer players. The sample consisted of 20 male soccer players (22.80 ± 2.71 years, 1.88 ± 0.06 m, 76.47 ± 8.80 kg) who comp...

Based on heavy aircraft main landing gear tires touchdown skidding process, patents have been registered since the 1940s to improve tire safety, decrease the substantial wear and smoke that results from every landing by spinning the rear wheels before touchdown. A single wheel has been modeled as a mass-spring-damper system using ANSYS mechanical transient simulation to analyze static and pre-r...

Abstract—In this paper we extend CSL (Continuous Stochastic Logic) with an expected time and an expected reward operator, both of which are parameterized by a random terminal time. With the help of such operators we can state for example that the expected sojourn time in a set of goal states within some generally distributed delay is at most (at least) some time threshold. In addition, certain ...
