Use of digital healthcare solutions for care delivery during a pandemic-chances and (cyber) risks referring to the example of the COVID-19 pandemic
AbstractDuring pandemics, regular service provisioning processes in medical care may be disrupted. Digital health promises many opportunities for service provisioning during a pandemic. However, a broad penetration of medical processes with information technology also has drawbacks. Within this work, the authors use the COVID-19 pandemic to analyze the chances and the risks that may come with using digital health solutions for medical care during a pandemic. Therefore, a multi-methods approach is used. First we use a systematic literature review for reviewing the state of the art of digital health applications in healthcar...

Multiclass classification of metabolic conditions using fasting plasma levels of glucose and insulin
AbstractIn clinical practice, plasma glucose concentrations in fasting and postprandial are measured to assess glucose metabolism and to diagnose diabetes. Plasma glucose and insulin concentrations in fasting and postprandial have been used to better characterize normal, prediabetic and diabetic conditions. In this paper, we seek to automatically recognize nine classes of metabolic conditions (three normal, three prediabetics, and three diabetics) by considering the age the patient and its fasting plasma glucose (FPG) and insulin (FPI) concentrations.

Solution of Lagrange's equation of motion form the first principle for volumetric modulated arc therapy delivery
AbstractTo calculate the Lagrange ’s equation of motion from first principle for volumetric modulated arc therapy delivery. The delivery of volumetric modulated arc therapy (VMAT) is based on a rotational co-ordinate system. This delivery technique differs from any other delivery technique with static beams. VMAT delivery is a com plex many-body problem, to represent the VMAT uniquely, it is necessary to find the equation of motion in a non-inertial (rotating) fame. In the non-inertial frame of reference, Newton's equations of motion do not hold, hence Lagrange's equation of motion (Lagrange's equation of motion of s...

Design and synthesis of filter bank structures based on low order constrained least square and minimum phase methods for audiogram matching in digital hearing aids
AbstractFrequency decomposer or filter bank plays acritical role in the design of digital hearing aid systems.This paper proposes filter bank structures suitable for the design of optimal hearing aid systems.The performance indices such as complexity, power dissipation, area utilization, delay, matching error of the filter banks are very competitive when compared to the designs in literature.Constrained least square finite impulse response filter with smooth transition band characteristics is used in the first method.The second method is based on Minimum phase filters with reduced number of coefficients which exhibit the s...
