There are several methods to count the number of real roots of an univariate polynomial p(x) ∈ R[x] of degree n (for details we refer to [BPR]). Among them, the Sturm algorithm says that the number of real roots of p(x) is equal to the number of Permanence minus the number of variations of signs which appears in the leading coefficients of the signed remainders sequence of p(x) and p(x). Anothe...

Background. Parkinson’s disease (PD) is characterized by motor and non-motor symptoms that affect patients’ functional performances, especially while performing dual tasks which is a critical factor in connection with everyday living.

Ventilated windows have shown great po tential in conserving energy in buildings and provide fresh air to improve indoor air qua lity. This paper reports our effort to use EnergyPlus to simulate the energy performance of a dual airflow window under different climate. Our investigation first develope d a network m odel to accoun t for th e twodimensional heat transfer in the window sy stem and i...
