Resistors In Series01:10

Resistors In Series

6.6K
A resistor is an ohmic device that limits the flow of charge in a circuit. Most circuits have more than one resistor. If several resistors are connected together and connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. The equivalent resistance of a combination of resistors depends on both their individual values and how they are connected. The simplest combination of resistors is the series combination. 
In a series circuit, the...

Series Resonance01:17

Series Resonance

837
The RLC circuit impedance is defined as the ratio of the supply voltage to the circuit current. Resonance in such a circuit occurs when the imaginary part of this impedance equals zero. This specific condition means that the inductive reactance is exactly equal to the capacitive reactance. The frequency at which this happens is known as the resonant frequency. Mathematically, the resonant frequency is inversely proportional to the square root of the product of the inductance (L) and capacitance...

Series and Parallel Capacitors

9.6K
Capacitors, fundamental components in electronic circuits, can be connected in series and/or parallel configurations. Each configuration has different impacts on the overall behavior of the circuit.
First, consider capacitors connected in series to a battery. In this configuration, the plate connected to the battery's positive terminal develops a positive charge, while the plate attached to the negative terminal becomes negatively charged. An equal magnitude of charge is induced on the...

Trigonometric Fourier series01:17

Trigonometric Fourier series

808
Fourier series is a foundational mathematical technique that decomposes periodic functions into an infinite series of sinusoidal harmonics. This method enables the representation of complex periodic signals as sums of simple sine and cosine functions, facilitating their analysis and interpretation in various fields, including signal processing, acoustics, and electrical engineering.
The trigonometric Fourier series specifically expresses a periodic function with a defined period T using sine...

Convergence of Fourier Series01:21

Convergence of Fourier Series

406
The Fourier series is a powerful mathematical tool for representing periodic signals as an infinite sum of complex exponentials. In practice, this infinite series is truncated to a finite number of terms, yielding a partial sum. This truncation makes the approximation of the signal feasible but introduces certain challenges, particularly near discontinuities, known as the Gibbs phenomenon.
The Gibbs phenomenon refers to the persistent oscillations and overshoots that occur near discontinuities...

Series R—L Circuit Transients

405
In a series resistor-inductor (R-L) circuit, closing the switch at the start of the time period simulates a three-phase short circuit, a fault condition where all three phases of an unloaded synchronous machine are short-circuited. When there is no fault impedance and no initial current, the initial voltage is determined by the phase angle of the source voltage.
Using Kirchhoff's Voltage Law (KVL) to analyze this circuit helps determine the total asymmetrical fault current, which consists...

Area of Science:

  • Minimally Invasive Surgery
  • Endocrine Surgery
  • Surgical Oncology

Background:

  • Posterior retroperitoneoscopic adrenalectomy offers advantages over transperitoneal approaches.
  • Surgeons often prefer transperitoneal adrenalectomy due to a familiar, wider working space.

Purpose of the Study:

  • To evaluate the feasibility and safety of posterior retroperitoneoscopic adrenalectomy.
  • To compare outcomes of initial cases with existing worldwide literature.

Main Methods:

  • Retrospective analysis of the first 10 patients undergoing posterior retroperitoneoscopic adrenalectomy.
  • Data collected: diagnosis, tumor size, operation time, blood loss, conversion rate, morbidity, mortality, and length of stay.

Main Results:

  • Included diverse adrenal tumors (pheochromocytomas, Conn's, Cushing's, non-functioning).
  • Mean operation time: 46.7 minutes; negligible blood loss.
  • One conversion (10%) due to prior trauma; no morbidity or mortality; mean hospital stay: 2.2 days.

Conclusions:

  • Outcomes align with larger published series regarding operation time, blood loss, and complication rates.
  • The technique is safe and feasible, even for surgeons new to the procedure.
  • Further patient data collection is planned for validation.
