In the field of Intelligent Transport Systems (ITS), inter-vehicle communication systems are actively researched for the purpose of decreasing the number of traffic accidents. In particular, reduced visibility due to buildings and vehicles is a significant cause of right-turn accidents and head-on accidents. The Inter-Vehicle Communication system enables the position of a vehicle to be transmit...

This study aimed to compare the effect of teaching metacognitive listening strategies through shadowing activity on the listening comprehension of field-dependent (FD) and field-independent (FI) EFL learners. Since the researcher had access only to female participants,85 female EFL learners from a language institute in Tehran, at the pre-intermediate level of proficiency with the age range of 1...

The energy efficiency of the urban texture relies notably on the buildings’ form, which characterizes its capability to take profit of the solar potential as well as its loss of energy through the envelope. Therefore, the general layout at the district scale has a significant impact on the global energy balance in a dense built environment, where the relative position of the adjacent buildings ...

Pronunciation is essential to appropriate communication because the incorrect use ofpronunciation inevitably leads to the message being misunderstood by the receptor. In spite of itsimportance, L2 learners often regard pronunciation as the most difficult language skill to learn.In this study, shadowing as an act or task in pronunciation, in which the learner tracks the targetspeech and repeats ...

This paper proposes a new wireless enabling technology for future smart radio environments. The approach aims to enhance signal coverage within the shadow region(s) of networks with aid so-called ’intelligent edges (IEs)’. IEs may be installed at fringes shadowing objects such as buildings, walls and other obstacles which obscure optical path from transmitter receiver. We investigate two differ...

In times of higher market prices of fossil fuels and to meet the increasingly environmental and economic threads of climate change renewable energy must play a major role for global energy supply. This paper focuses on a new method for fully automated solar potential assessment of roof planes from airborne LiDAR data and uses the full 3D information for both, roof plane detection and solar pote...

This work presents an accurate and realistic positioning approach for indoor environments based on fingerprinting and raytracing techniques. Fading caused by multipath seriously degrades the performance of communication systems operating inside buildings. For this reason, the proposed localization method considers multipath effects due to reflections and diffraction from walls, roof and floor. ...

Wireless network protocols are commonly evaluated through simulations. The achieved results may vary significantly with the modeled propagation environment. Protocols that use carrier sensing for collision avoidance may not operate properly in the presence of obstacles (e.g. buildings) that shield hosts from each other. These failures may not be recognized when using a long-term stochastic mode...

Some characterizations on the chain recurrence, chain transitivity, chain mixing property,shadowing and $h$-shadowing for Zadeh's extension are obtained. Besides, it is provedthat a dynamical system is spatiotemporally chaotic provided that the Zadeh's extensionis Li-Yorke sensitive.
