a variety of semiautomatic methods, based on the use of derivatives of the magnetic anomalies, have been developed for the determination of both of the causative source parameters such as locations of boundaries and depths. one of these techniques is the method of the analytic signal for magnetic anomalies, which was initially used in its complex function form and makes use of the properties of...

gravity and magnetic data are usually processed and interpreted separately, and fully integrated results basically are created in the mind of the interpreter. data interpretation in such a manner requires an interpreter experienced both on topics concerning potential field theory and the geology of the study area. to simplify the joint interpretation of data, the automatic production of auxilia...

Elsewhere in this issue Ferdinand Verhulst described the discussion of the interaction of analysis and geometry in the 19th century. In modern times such discussions come up again and again. As of 2014, synthetic geometry will not be part of the Dutch ‘vwo – mathematics B’ programme any more. Instead, the focus will be more on analytic geometry. Mark Timmer and Nellie Verhoef explored possibili...

there are many evident that people are more interested in walking in attractive urban spaces and inappropriate physical and psychological condition can reduce their presence in a remarkable amount. the current research investigates the influence of physical design and psychological elements and their criteria on selective physical activity and specifically walking in urban public spaces. howeve...

In Indonesia, Dualism And Secularism Have Posed Serious Challenges To Theological Higher Education Particular. These Led A Dis-integration Mis-integration Between Theology Science Resulted Confusion, Hypocrisy, Paralysis, Stagnation. This Study On The Integration Of Science, Using Integrative Research Methods, Attempts Find An Analytical-synthetic Model That Provides Introduction Studies, Such ...
