In 1988, Professor Isakov joined Wichita State University as a Professor of Mathematics specializing in Partial Differential Equations and Inverse Problems. In 2000, he went on to become the Emylou Keith and Betty Dutcher Faculty of Distinction Endowed Professor due to his outstanding contributions to research in the area of inverse problems. Professor Isakov was recognized as a world-class authority in inverse problems, and he produced many original and breakthrough results for linear and nonlinear inverse boundary value problems. He authored 140 papers in mathematical journals and three books in the subjects of inverse problems and mathematical physics. He also organized several conferences around the world and advised many graduate students. His research has continuously been supported by NSF since 1990. His passing is a huge loss to both the Wichita State University and the inverse problem community

Measuring and analyzing German and Spanish customer satisfaction of using the iPhone 4S Mobile Cloud service
Full text linkThis paper presents the customer satisfaction analysis for measuring popularity in the Mobile Cloud, which is an emerging area in the Cloud and Big Data Computing. Organizational Sustainability Modeling (OSM) is the proposed method used in this research. The twelve-month of German and Spanish consumer data are used for the analysis to investigate the return and risk status associated with the ratings of customer satisfaction in the iPhone 4S Mobile Cloud services. Results show that there is a decline in the satisfaction ratings in Germany and Spain due to economic downturn and competitions in the market, which support our hypothesis. Key outputs have been explained and they confirm that all analysis and interpretations fulfill the criteria for OSM. The use of statistical and visualization method proposed by OSM can expose unexploited data and allows the stakeholders to understand the status of return and risk of their Cloud strategies easier than the use of other data analysis

coefficient ,
in the elliptic equation div in ,
when overdetermined boundary data for one nontrivial solution u are
assigned. We show that nonuniqueness in the detennination of the domain
D would imply that a part of is a
solution of a particular free boundary problem. We prove analyticity
properties of such a free boundary and, consequently, we derive uniqueness
results for the inverse conductivity problem

A Norwegian grey zone: Knut Rød, Victor Lind and 'The crucial year, 1942'
No full textThis article uses Primo Levi’s concept of “the grey zone” to explore Knut Rød’s involvement in the transfer of 532 Norwegian Jews from Oslo to Auschwitz in 1942. Rød, the police chief in charge of the operation, was subsequently exonerated of any crime on the grounds that he had simultaneously used his position to help members of Milorg – the Norwegian Resistance. The legal and moral basis of this verdict has been questioned by the artist Victor Lind in a series of artworks, including his “countermonument” The Perpetrator (2005)
