Over the last decade, there has been rising interest in automated driving systems and adaptive cruise control (ACC). Controllers based on reinforcement learning (RL) are particularly promising for autonomous driving, being able to optimize a combination of criteria such as efficiency, stability, comfort. However, RL-based controllers typically offer no safety guarantees. In this paper, we propo...

In the solar coronal numerical simulation, heating/acceleration and magnetic divergence cleaning techniques are very important. The coronal–interplanetary total variation diminishing (COIN-TVD) magnetohydrodynamic (MHD) model is developed in recent years that can effectively realize three-dimensional (3D) wind simulation. this study, we focus on 3D simulation by using COIN-TVD MHD model. order ...

the earth’s gravity field dedicated missions, champ, grace and goce have opened up a new era for the study of the earth’s gravity field. the missions measure different functionals on the earth’s gravitational potential which are represented in terms of the stokes coefficients or the so-called geopotential models. the mapping process of the observations into the coefficients is called recovery o...

This paper presents a study of field line visualization techniques. To address both the computational and perceptual issues in visualizing large scale, complex, dense field line data commonly found in many scientific applications, a new texture-based field line representation which we call selforienting surfaces is introduced. This scalable representation facilitates hardware-accelerated render...

Since their introduction in constructive cryptographic applications, pairings over (hyper)elliptic curves are at the heart of an ever increasing number of protocols. Software implementations being rather slow, the study of hardware architectures became an active research area. In this paper, we discuss several algorithms to compute the ηT pairing in characteristic three and suggest further impr...

“It is here proposed that the frequency of word occurrence in an article furnishes a useful measurement of a word significance. It is further proposed that the relative position within a sentence of words having a given value of significance furnishes a useful measurement for determining the significance of sentences. The significance factor of a sentence will therefore be based on these two me...

Regulatory genes are believed to play a large role in morphological diversification and are often characterized by elevated rates of evolution. Whether this rapid evolution is primarily due to adaptive differentiation or relaxed selective constraint remains an open question. We attempted to distinguish between these alternative outcomes in 2 transcription factors known to regulate the expressio...

vibration generated by vehicles during road transport has an important impact on agricultural products' damage process, particularly in the case of fruits and vegetables. modulus of elasticity is one of the most conspicuous mechanical properties of fruits, the variation in which can be described as one of the most affecting damage criteria during transportation. this research was conducted...

a major constraint to the application of any form of knowledge and principles is the awareness, understanding and acceptance of the knowledge and principles. systems thinking (st) is a way of understanding and thinking about the nature of  health systems and how to make and implement decisions within health systems to maximize desired and minimize undesired effects. a major constraint to applyi...
