The research involves the design and analysis of methods for trajectories of objects moving in 2- or 3-dimensional space. A proper definition of a “median trajectory” based on a collection of trajectories is sought, as well as efficient algorithms for computing such a median. The definition and algorithms should be robust when noise or outliers are present. The research continues by investigating how median trajectories can be used in various applications. These include trajectory collection visualization, trajectory clustering, classification, and related problems, for which efficient algorithms and implementations should be developed. This will be done in collaboration with researchers in these application areas, whose data will be used.

The research will lead to scientific papers in the fields of computational geometry and geographic information science, to be published in conference proceedings and journals. The collective research results will lead to a PhD thesis. (more…)

Vacancies for 10 PhD positions
Bauhaus-Universität Weimar, Germany. DFG – Research Training Group 1462 as of June 2011 / TV- L 13 E, max. 3 years

The research training group “Evaluation of Coupled Numerical Partial Models in Structural Engineering” is offering 10 positions for doctoral students for its second project phase. We are looking for inspired and dedicated individuals who are interested in doing research work in the multi-faceted field of structural engineering.

The overall aim of the Research training group is to assess the reliability, safety and robustness of numerical models. This evaluation considers a wide range of aspects and models. This includes, but is not restricted to, models that describe loads or the material and structural behavior of systems in structural engineering. Of particular interest are the interactions of these models in complex systems. Their influence on the quality of models of complex coupled systems is to be determined.

The University of Rome “La Sapienza” offers 16 three year full-time postgraduate PhD positions with fellowship for attaining the degree of “Dottore di Ricerca” (PhD) in the Doctoral Schools listed in appendix.

Each fellowship amounts to € 19.800,00 per year; this amount includes national insurance contributions (INPS) that fellowship recipients are required to pay (8,91% for 2011).

The fellowship doesn’t cover the annual entrance fee and doesn’t increase for research periods spent abroad.

The PhD Programme lasts three years and may be extended to a fourth year (without grant), subject to approval by the School authorities. At the end of the first and second year of attendance, students have to be evaluated as proficient according to the rules of the Schools.

The University of Central Lancashire offering International PhD Scholarship in Silica templates for selective extraction of radionuclides (SiTSER), UK

Applications are invited for a full-time scholarship available in the School of Forensic & Investigative Sciences. The scholarship is tenable for up to 3 years for a PhD (via MPhil route) [subject to satisfactory progress] and is open to international applicants only. UK/EU applicants are not eligible to apply. The scholarship will provide £15000 towards the cost of the International tuition fee over 3 years.

A variety of adsorbents such as carbon, hydrogels, clays, silca gels etc employed for the removal of radionuclides from aqueous solutions have been reported; but each has inherent limitations. The discovery of mesoporous materials with large surface area and wide uniform pores has provided a new dimension for the removal/recovery of radionuclides.
