Introduction: Epidemiologic data of upper extremity tumors are still few and sometimes conflicting. In our department, hand surgeons manage these tumors. Good documentation of patients’ information permitted us to make an epidemiologic study on the tumors of the upper extremity operated in our department. Methods: We retrospectively studied all the cases of upper extremity tumors operated from...

We present a constraint-based model and planning engine for manufacturing process planning. By exploiting the expressive power of constraint programming (CP), all relevant, sometimes conflicting pieces of domain knowledge are represented. The planner applies standard propagation techniques and customized search to find cost-optimal solutions in presence of hard, soft and conditional constraints...

OBJECTIVE A variety of imaging and clinical guidelines have been developed to assist radiologists and referring physicians in the workup of incidental adrenal masses. The objective of this article is to provide a concise review of incidental adrenal mass imaging and present the key differences between the available guidelines. CONCLUSION An alternative algorithm for the imaging and clinical w...

Autonomous navigation in urban environments inevitably leads to having to switch between various, sometimes conflicting control tasks. Sting Racing, a collaboration between Georgia Tech and SAIC, has developed a modular control architecture for this purpose and this paper describes the operation and definition of this architecture through so-called nested hybrid automata. We show how to map the...

Optimality criteria of the experimental design in dynamic system identification may sometimes be conflicting for structure determination and parameter estimation steps. This leads the necessity of the tradeoffs between the performances in these two steps. Here, the optimal input design in system identification is investigated as a multi-objective optimization problem. The Pareto-optimal set of ...

Studies of workers in health care and the care of older people disclose tensions that emerge partly from their conflicting obligations. They incur some obligations from the personal relationships they have with clients, but these can be at odds with organizational demands and resource constraints. One implication is the need for policies to recognize the importance of allowing workers some disc...
