7.4.1.1 Dielectric withstanding voltage The purpose of this test is to prove that a connector can operate safely at its rated voltage and will be able to withstand momentary over potentials due to switching, surges and other similar phenomena. The applied voltage can be either AC or DC. The voltage should be applied across the two closely spaced contacts as well as between a connector shell and the contacts closest to the shell. The test voltage in the case of coaxial connectors shall be applied between the inner and outer conductor. The voltage should be ramped up uniformly from zero to rated value. The test can be performed at various pressures depending on the application in which the connector is going to be used. For example, in undersea application the pressure will be high on the connectors. [26] 7.4.2 Insulation Resistance Testing …show more content…
[26]. The insulation resistance is measured using a mega ohm bridge or a mega ohm meter. An applied DC voltage is used to measure the insulation resistance of the connectors in kΩ, MΩ, or GΩ. If the connector is going to operate at special conditions, then the environmental requirements needs to be incorporated. The electrical insulation begins to age as soon as it is installed, this deterioration can affect the performance. It is used as quality control during production of the connector, preventive maintenance tasks and as a troubleshooting

227 Words | 1 PagesThe power spectral densities ($PSD$) of the gas jet centerline $C^*(t)$ for the tests in Tab.\ref{Table} were computed via $FFT$, and collected in Fig.\ref{Spectra}. For plotting purposes, the frequency domain $f_j$ is limited to $f_j=150 Hz$, and the $PSD$ in each graph is normalized with respect to the maximum $PSD$ detected within the three tests. Regardless of the stand-off distance $\hat{Z}$, for $\hat{Y}=0$ the response of the jet to the membrane motion is the superimposition of a harmonic response $f_h$ and a higher frequency $f_f$, which is not affected by the membrane motion. Noteworthy, $f_f$ scales with the standoff distance and leads to a constant Strouhal number $St_Z= f_f Z/U_j\approx 0.08$, not far from the $St_Z=0.12$ \cite{Vshape}

Only one condition $Cin A$ can be extit{true} at the same time and no state transition without being specified by a condition is possible. If condition $C_{i,L_j}$ is not extit{true} any more (due to the proceeding of the assembly operation), there is a fallback to state $S_{j,L_i}$ and all conditions are evaluated to determine the current substate. An exemplary decomposition tree containing different hierarchical levels, multiple states per level and conditions for state transition is given by Fig.~

The main purpose of a digital forensic report is to keep the data integrity, avoiding any type of data alteration, in order to present valid evidences, for instance in a court. The use of not valid software to check the stored information in a mobile phone can alter these information. The action of receive new data can alter the information stored, for instance an automatic firmware update, or remote device control with the risks involved. Therefore, it is extremelly important have the device completely isolated from the network.

I’m a huge fan of the piano, so I knew that I wanted to incorporate a piano in the piece. Surprising enough the main part of the whole piece is the pinaoloop2 on a loop. The work process for this piece primarily involved getting the audio samples that will work nicely around my main piece which is the pianoloop2. After obtaining the audio files, the major software that I use to get the sounds together was Audacity.

Ductile Fracture Case Study
800 Words | 4 PagesA primary use of the Charpy and Izod tests is determining if a material experiences brittle to ductile transition with a decreasing temperature. Brittle to ductile transition is directly related to the temperature dependency of the impact energy absorbed. An examination of the failure surface can prove very beneficial. When a section of the failure surface seems to demonstrate appears to demonstrate the visual properties of both the brittle and ductile fracture, then the brittle to ductile transition is evident at that temperature range. It is really important to remember that with most specimens, there is a fairly wide band of temperatures which support brittle to ductile transition.

Ohm's Law Lab Report
1206 Words | 5 Pages¬¬¬¬¬¬Abstract Electrical circuits are described with mathematical expressions. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current and Voltage Laws, which govern the currents entering and exiting a circuit node and the sum of voltages around a circuit loop, respectively. Objective(s) The purpose of this experiment is to verify Ohm's Law using resistor in dc and ac circuits.
