In this paper, we propose an analytical approach for the small-signal response of nanometric InGaAs diode which is extracted to the transistor model in ref [1] when the gate is taking away. The exploitation of the small-signal equivalent circuit elements such as the admittance parameters can give significant information about the noise level of the devices by using the Nyquist relation. The ana...

PURPOSE To evaluate modified acoustic reflex diagnostic protocols for a group of individuals (n = 9) with high peak compensated static acoustic admittance (Y(tm)) tympanograms. METHOD A modified procedure designed to improve acoustic stapedius reflex threshold (ASRT) measurements in individuals with high-admittance tympanograms was employed in both an experimental and a control group. ASRTs w...

Assessing the geomagnetic hazard to power systems requires reliable modelling of the geomagnetically induced currents (GIC) produced in the power network. This paper compares the Nodal Admittance Matrix method with the Lehtinen–Pirjola method and shows them to be mathematically equivalent. GIC calculation using the Nodal Admittance Matrix method involves three steps: (1) using the voltage sourc...

This paper discusses a new approach to haptic feedback for teleoperation of hovering vehicles. Traditionally airplane and helicopter controls use the displacement of a joystick as the main supervisory control input. It is common to overlay force feedback to convey additional information about forces occuring in the controlled craft. However, there are some fundamental problems when trying to fe...

BACKGROUND The aims of the present study were to investigate clinically relevant patient and environment-related predictive factors for threats and violent incidents the first three days in a PICU population based on evaluations done at admittance. METHODS In 2000 and 2001 all 118 consecutive patients were assessed at admittance to a Psychiatric Intensive Care Unit (PICU). Patient-related con...

Most techniques for power system analysis model the grid by exact electrical circuits. For instance, in power flow study, state estimation, and voltage stability assessment, the use of admittance parameters (i.e., the nodal admittance matrix) and hybrid parameters is common. Moreover, network reduction techniques (e.g., Kron reduction) are often applied to decrease the size of large grid models...

BACKGROUND Specialised palliative care (SPC) takes place in specialised services for patients with complex symptoms and problems. Little is known about what determines the admission of patients to SPC and whether there are differences in relation to institution type. The aims of the study were to investigate whether cancer patients' admittance to SPC in Denmark varied in relation to sex, age an...

This paper presents the design, construction and testing of a device to measure pressure-volume loops in the left ventricle of conscious, ambulatory rats. Pressure is measured with a standard sensor, but volume is derived from data collected from a tetrapolar electrode catheter using a novel admittance technique. There are two main advantages of the admittance technique to measure volume. First...

UNLABELLED The diabetic patients represent a population with a high risk of morbidity and mortality because of vascular complications. Out of them, all the patients with acute ST-elevation myocardial infarction have a more reserved prognostic than those without diabetes mellitus. Moreover, the patients with impaired glucose tolerance have a more severe evolution in case of a myocardial infarcti...
