In September 2006, the Second International Workshop on Parameterized and Exact Computation was held in Zürich, Switzerland, as part of ALGO 2006. At the end of IWPEC 2006, a problem session was held. (Most of) the problems mentioned at this problem session, and some other problems, contributed by the participants of IWPEC 2006 are listed here.

Abstract. The Levi-Civita transformation is applied in the two-dimensional (2D) Dirac and Klein-Gordon (KG) equations with equal external scalar and vector potentials. The Coulomb and harmonic oscillator problems are connected via the LeviCivita transformation. These connections lead to an approach to solve the Coulomb problems using the results of the harmonic oscillator potential in the above...

All systems for managing data face common problems such as backup, recovery, auditing, security, data integrity and concurrent update. Other challenges include the ability to share data easily between applications and to distribute data across several computers, while continuing to manage the problems already mentioned. Geographic information systems are no exception, and need to tackle all the...

Design-to-time scheduling problems are real-time problems where multiple methods are available for many subproblems. This paper briefly summarizes recent work empirically investigating the design-totime search space. The effects of several parameters on the difficulty of the scheduling are mentioned and discussed.

BACKGROUND There has been an increase of reports describing mental health problems in adolescents, especially girls. School nurses play an important role in supporting young people with health problems. Few studies have considered how the nurses' gender norms may influence their discussions. METHODS To investigate this issue, semi-structured interviews focusing on school nurses' work with stu...

Marma science (traumatology) is a unique specialty of Ayurveda that plays significant role in surgical procedures and treatments. Acharya Sushruta has described Urvi as part the Sira marma (a vital point which vascular nature), he mentioned traumatic disorders associated with it. In order to apply Sushruta's invaluable knowledge current era, it necessary precisely correlate his concept present ...
