This chapter illustrates how student activism, taken in the context of the student voice, can be harnessed as a way of enhancing the quality of educational provision in higher education. Agenda 2063 of the African Commission recognizes equitable access to quality higher education as critical for national development. In the face of an increase in stu‐ dent protests and the resultant destruction...

The urban micro climate is important for the well-being of citizens. With simulation models the urban micro climate can be studied and recommendations can be made to improve the micro climatic situation. However, mainly synthetic scenarios are simulated due to a lack of information. The objective of this paper is to explore the potential of airborne hyperspectral and height data to provide area...

Web services have the potential to radically enhance the ability of researchers to make use of distributed computing resources, but jargon and a plethora of standards make their use almost impossible for the scientist who has no prior experience of the necessary technologies. A powerful and simple WSRFbased middleware scheme is presented, designed to let scientists remotely deploy single or mul...

A clinical trial is a study designed to demonstrate the efficacy and safety of a drug, procedure, medical device, or diagnostic test. Since clinical trials involve research in humans, they must be carefully designed and must comply strictly with a set of ethical conditions. Logistical disadvantages, ethical constraints, costs and high execution times could have a negative impact on the executio...

Many algorithms have been proposed to automatically find spectral endmembers in hyperspectral data sets. Perhaps one of the most popular ones is the pixel purity index (PPI), available in the ENVI software from Exelis Visual Information Solutions. Although the algorithm has been widely used in the spectral unmixing community, it is highly time consuming as its precision increases asymptotically...

The purpose of the present paper to estimate the impact of alterations in urban design on local microclimate in three different locations: a densified area of São Paulo, Brazil, a district in Paris, France and an industrial area in Geneva, Switzerland, which is undergoing urban redevelopment. Computer simulations were run with the program ENVI-met in all cases, including a calibration procedure...

The most widely known remote-sensing data are satellite images (typically LANDSAT or other visible imagery), which are used in the geosciences for a multitude of applications, including landuse, urbanization, sea-ice expansion, to name only a few. Commonly, these remote-sensing data are analyzed with the help of commercial software systems (eg. ENVI, ERDAS-IMAGINE). Analysis methods employ the ...

The coastal region of Chabahar Gulf with 1113.7km2 area has been located in the southeast of Iran. In this research, satellite images of ETM+ (2004) were used in order to zoning of sedimentary environments in this Gulf. Methodology of this research was baesd on synthesis of supervised and unsupervised classifications in GIS and ENVI softwares. Based on studies and calculat...

This paper proposes a useful technique for generating an earth resistivity map. Earth resistance is one of essential factors in a broad range of power system analysis and design. Information of earth resistivity is helpful for practical power system engineers in order to establish power system grounding. In this paper, a LANSAT7 image of a tested area of 50 km was used by ENVI program in associ...
