The Wigner time delay of slow particles in the process their elastic scattering by compound targets consisting several centers modeled zero-range potentials is studied. It shown that at asymptotically large distances from target, Huygens-Fresnel interference pattern formed spherical waves emitted each transformed into a system generated geometric center target. These wave functions determine fl...

BACKGROUND Prevalence of communication delays or disorders is increasing, possibly because of various environmental risk factors. Selection and implementation of effective screening tools are important to detect at-risk infants as early as possible. This study aimed to evaluate the accuracy of the Parents' Evaluation of Developmental Status (PEDS), PEDS-Developmental Milestones and PEDS tools t...

The paper discusses modeling and analysis of real-time systems subject to random time delays in the communication network. A new method for analysis of existing schemes is presented. The method is used to evaluate diierent suggested schemes from the literature. A new scheme for handling the random time delays is then developed and successfully compared with previous schemes. The new scheme is b...

Retroperitoneal sarcomas are rare and treatment should optimally be centralized. Despite successful centralization with 90% of the patients referred prior to surgery, delays occur, which led us to assess lead times in a population-based series. Method. Patients diagnosed with retroperitoneal sarcoma in the southern Sweden health care region 2003-2009 were eligible for the study. Data on referra...

Power is increasingly the primary design constraint for chip designers and one of the main techniques for addressing this concern is aggressive voltage scaling. Device variability increases with voltage scaling and significantly affects gate delays at low voltages. Although existing delay models for nearand sub-threshold circuits captures the effects of variability on gate delays, they do not c...

This paper presents the central finite-dimensional H∞ filters for linear systems with state and measurement delays, that are suboptimal for a given threshold γ with respect to a modified Bolza-Meyer quadratic criterion including the attenuation control term with the opposite sign. The paper first presents the central suboptimal H∞ filter for linear systems with state and measurement delays, whi...
