abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
This study represents advancements in the state-of-the-art of the solar energy industry by leveraging LiDAR-based building characterization for city-wide, distributed solar photovoltaics, solar maps, highlighting the distribution of solar energy across the city of San Antonio. A methodology is implemented to systematically derive the tilt and azimuth angles of each rooftop and to quantify solar...
Abstract: The purpose of this paper is to design and evaluate the construction of a lightweight solar aircraft that is capable of flying continuously for 24 hours relying solely on solar energy. The required energy is absorbed during the day by solar panels, some is used directly for flight, and the excess energy is stored in the aircraft battery for overnight flight. The aircraft will then be ...
Passive solar systems such as solar chimneys need solar radiation in order to work. Therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. Phase change materials can save additional thermal energy during the day and release it during the...
the significance of the study of deixis was then mentioned. the purpose of the present study from the outset was to provide a comprehensive overview of all kinds of deixis in persian, describing and defining each in true while considering them structurally and semantically. chapter two consisted of two main parts. a review of the english studies in this respect, besides presenting persian liter...
Introduction • Raster maps are a rich source of geospatial data: — Easily accessible — Many different types of information — Often contains information that cannot be found elsewhere Challenges • Maps have lots of useful information, but… — They have overlapping features — There is limited access to the meta-data — Often only available in raster format • How do we find, register, and extract an...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
Local solar irradiation data has been used for Model Predictive Control (MPC) in supervisory level building control systems, with significant influence demonstrated on perimeter building zones with a high fraction of window area. This work investigates the impact of uncertain solar estimation on MPC performance with respect to energy consumption and comfort by comparing MPC responses for a mult...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
The lack of reliable data for ground solar irradiance (direct normal and global irradiance) is a major obstacle for the development of adequate policies to promote and take advantage of existing solar technologies. Although the radiation that reaches the outer layers of the atmosphere is well defined and can be easily calculated, the solar irradiance that reaches the ground level where solar co...
