Four different restorationcommunities (labeled as ecological restoration treatment Ⅰ, Ⅱ, Ⅲ and Ⅳ) were selected byspace-time replacement method according to the erosion intensity in degraded purple soil ecosystem.The results showed that there were totally 86 plant species belonging to 78 genera and 43 familiesin the degraded purple soil ecosystem. Of the 15 types of distribution area in spermatophyte genus,12 types were found in the purple soil ecosystem. Along restoration gradient from low to high, plantgrowth type and life form spectra became abundant more and more, and the spermatophyte genera foreach distribution area type and genera numbers for different foliage characters increased as well.It is concluded that the plant flora and physiognomy in ecological restoration process become morecomplex and diverse, indicating that the forest ecosystem on purple soil tends to be more stable.展开更多

To assess the possible correlations between personality traits （also measured intelligence） and face images, we first construct a dataset consisting of face photographs, personality measurements, and intelligence measurements. Then, we build an end-to-end convolutional neural network for prediction of personality traits and intelligence to investigate whether self-reported personality traits and intelligence can be predicted reliably from a face image. To our knowledge, it is the first work where deep learning is applied to this problem. Experimental results show the following three points： 1） ＂Rule-consciousness＂ and ＂Tension＂ can be reliably predicted from face images. 2） It is difficult, if not impossible, to predict intelligence from face images, a finding in accord with previous studies. 3） Convolutional neural network （CNN） features outperform traditional handcrafted features in predicting traits.展开更多

The main objective of the research is to produce an accurate nationwide vegetation physiognomic map by using automated machine learning approach with the support of reference data. A time-series of the multi-spectral and multi-indices data derived from Moderate Resolution Imaging Spectroradiometer (MODIS) were exploited along with the land-surface slope data. Reliable reference data of the vegetation physiognomic types were prepared by refining the existing vegetation survey data available in the country. The Random Forests based mapping framework adopted in the research showed high performance (Overall accuracy = 0.82, Kappa coefficient = 0.79) using 148 optimum number of features out of 231 featured used. A nationwide vegetation physiognomic map of year 2013 was produced in the research. The resulted map was compared to the existing MODIS Land Cover Type (MCD12Q1) product of year 2013. A huge difference was found between two maps. Validation with the reference data showed that the MCD12Q1 product did not work satisfactorily in Japan. The outcome of the research highlights the possibility of improving the accuracy of the MCD12Q1 product with special focus on reference data.展开更多

It was the process to prevent and to secure a city as well as the territory from any kind of disruption and disintegration through the fortified walled profile. The strategies, approach, and positioning of those forts were governed by the contextual specification. All different forts of Mughals Empire had unusual notion of accomplishment. Fort architecture in the subcontinent was initially developed by the Mughals to protect the territory from the enemy. Later, those forts became huge and complex. The planning approach and the morphology of the fort architecture were justified according to the relative factor. The Mughal Fort is a Medieval-era building. The Mughal Fort improves the city＇s defensive strength and provides some culture at every turn, Building Walls is a prerequisite to settle the Mughal Fort. The Mughals were concern about environment. Mughals ruled most of the subcontinent until the mid-19th. During their rule they constructed elaborate forts across the countryside which served as administrative centers and living quarters for the occupiers. Bengal became a province of the Mughal Empire and was ruled from Delhi by the governors of Bengal （1576）.a Bengali river fort experienced lots of local and traditional influences only lbr being the river fort, stating from the component, elements of tbrts, and formal profile as well. Undoubtedly, Bengal conceived a different kind of river oriented fort, which has distinct characters. Even in the case of this fort formation, the Mughal had some strategic planning and morphology for spread city beyond the fort wall. The objective of the research is solely to identify distinguished characteristics and context specification and to analyze the morphology of the four-river fort architecture of East Bengal （Bangladesh）.展开更多

However, the exploitation can have many negative impacts on the immediate environment of the exploitation sites. In this study performed on some mining areas of the Moroccan Anti-Atlas, four principal negative effects were detected: effect on the physiognomy, on safety, on health, and on recovery rate. The principal source of this situation is the exploitation of the ore deposits from top to bottom without using any geological preparation and the use of non-adapted exploitation technics. To minimize these impacts, we propose to establish a geological study and advanced mining exploration before starting exploitation, and follow an exploitation technic well adapted to the morphology of the ore deposit like cut-and-fill mining and sublevel stoping methods.展开更多
