Especially, the vegetation index of Terra/MODIS-EVI is believed to have the highest sensitivity to the seasonality of vegetation. This study compares the reflection susceptibility of three vegetation indices (NOAA/AVHRR-NDVI, Terra/MODIS-NDVI and Terra/MODIS-EVI) to the seasonal variations of vegetation in the mid-south of Yunnan Province of China. It has been found that Terra/MODIS-EVI does best in the elimination of external disturbance. Firstly, it obviously improves the linear relationship with vegetation cover degree, especially in the high vegetation coverage area. Secondly, it avoids the emergence of vegetation index saturation. Thirdly, it reduces the environmental influence including both effects of atmosphere and soil. So it is believed that the Terra/MODIS-EVI can offer excellent tool for quantitative research of remote sensing, and has realized to be oriented by data with high quality.展开更多

This is due to the will to reach the targets of 20-20-20. Buildings consume a lot of energy, so the legal framework related to the reduction of energy consumption in this sector has had a huge evolution. The "NZEB (nearly zero energy building)" concept was introduced in 2010, eight years after the release of the original EPBD (energy performance of buildings directive). By 2020, all new buildings and buildings that are subject to renovation should have very low energy consumption, covered for the major part by renewable sources. Designing and realizing this kind of building is a very ambitious task, which needs to be supported by appropriate tools and software. This paper presents a new tool for assessing building performance, named BENIMPACT Suite (building's environmental impact evaluator and optimizer), which is developed by EnginSoft (Italy). The suite is organized in different core modules that allow to verify how the building performance level is influenced by different design choices, such as envelope shape and materials, plant systems, renewable sources use, etc.. One of the test cases used to validate the BENIMPACT Suite energy performance is the evaluation of an interesting Italian ZEB, finished in 2010 and called CasaZeroEnergy. It is located in Felettano (Udine), a small town in northeastern Italy. This building is an experimental house designed and monitored by the Laboratory of Building Design of the University of Trento (Italy) and built by Polo Le Ville Plus Group (Cassacco-ltaly). The energy performance of this building was modelled and evaluated using BENIMPACT Suite, and simulation results were compared with monitored data.展开更多

Creating this atmosphere encounters various challenges which are partially context-specific. Influenced by the learning environment, learnners of different educational contexts vary in their degree of autonomy. The present study examines the impact of the learning environment on learner autonomy at higher education. The study focuses on the differences between Polish and Yemeni EFL (English as a Foreign Language) learners with respect to their autonomy in language learning. A questionnaire was distributed to a total of 140 (59 Polish and 81 Yemeni) undergraduate learners. The questionnaire was coded into seven categories: beliefs and attitudes, planning, management, self-regulation, sources and materials, in-class responsibility, and out-of-class responsibility. Data were analysed quantitatively via SPSS (Statistical Product and Service Solutions). Independent Sample t-Test is used to investigate the differences between Polish and Yemein learners and Pearson Correlation is used to perform correlational analysis among the seven categories. The results show significant differences between Polish and Yemeni learners in some of the categories as well as a significant correlation among other categories展开更多
