Anderson and Wood (1925) determined a magnification value equal to 2800 but they neglected the deformation of the tungsten wire under different equilibrium situations. Conversely, the deformation of the wire could be sufficient to reduce the magnification factor of 30%, increasing the moment of inertia. For this reason Uhrhammer and Collins (1990) and Uhrhammer et al. (1996) recomputed the instrument static magnification (GS) that was estimated equal to 2080 ± 60. Using 2800 instead of 2080 in the BB WA simulations leads to a magnitude error of +0.129 (e.g. Uhrhammer et al., 2011). To verify the GS value of the Trieste instrument, we adopted two different approaches. The first one involves a direct action on the instrument. According to Anderson …show more content…
Tilting the instruments of a known angle b and measuring the output voltage from the PSD, which is proportional to A, from Eq. (1) we calculate GS (Table 1). The measures made on the N-S component of the instrument are more reliable than those on the E-W one that was repaired at best by the OGS technical staff after the partial detachment of the moving mirror. The error associated to with the estimate is evaluated as the amplifier error, equal to 1% on the linearity of the response, plus the uncertainty on the voltmeter, equal to 0.05 …show more content…
The earthquakes that have been considered are 1152, those for which a location was found in the catalogues: for 956 of them it was possible to calculate also, as additional information, the equivalent WA magnitude (MLBB). Indeed, since October 22, 2004 a Guralp 40-T BB seismometer with a period extended to 60 s was placed very close to the WA one. In addition, for 134 events recorded in the period 2010-2013 the equivalent ML was estimated both by the BB instruments placed at on the surface (MLBB) and at the bottom (MLTRI) of the cave (see Introduction). To compute the equivalent ML we have first deconvolved the BB instrument transfer function to obtain a ground displacement record and then we have convolved the signal with the WA transfer function. From May 26, 2005 to March 5, 2010 the WA and BB instruments were temporarily moved from their historical site to a temporary location due to the restoration of the hosting building. The recordings of that period were discarded in this study because the temporary location was not on hard

It can be seen that each figure shows a slight increase in CO2 production, which signifies a possible change in metabolic rate. Figures 4 and 7 show a relatively large change between the control and fox urine. The changes in slope between theses two are 0.0267 for Figure 4’s slopes and 0.0192 for Figure 7’s slopes.

310 Words | 2 PagesI need to find the area of rectangle ABCD. I know that ABCD is a rectangle with diagonals intersecting at point E. Segment DE equals 4x-5, segment BC equals 2x+6, and segment AC equals 6x. I predict that To find the area of rectangle ABCD I need to find out the base and height of the rectangle. The first step is to find what x equals. Since I know the intersecting line segments AC and DB are congruent that means when I times the equation 4x-5 for segment DE by two it will equal the equation 6x for segment AC.

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}

603 Words | 3 PagesSuppose we have a single-hop RCS where there is one AF relay that amplifies the signal received from a transmitter and forwards it to a receiver. Assume that the transmitter sends over the transmitter-to-relay channel a data symbol ${s_k}$, from a set of finite modulation alphabet, $S={S_1, S_2,ldots,S_{cal A}}$, where ${cal A}$ denotes the size of the modulation alphabet. The discrete-time baseband equivalent signal received by the relay, $z_k$, at time $k$ is given by egin{equation} z_k = h_{1,k}s_k + n_{1,k},~~~~for~~k=1,2,ldots,M label{relaySignal} end{equation} where $n_{1,k}sim {cal N}_c(0,sigma_{n1}^2)$ is a circularly-symmetric complex Gaussian noise added by the transmitter-to-relay channel, $h_{1,k}$ denotes the transmitter-to-relay channel, and

This process extends to other objects and real world applications, such as the controlling of electrical cable manufacturing and application in areas such as a television depot station, where static electricity must be managed and accounted for to avoid disruptions. As well as in micro surgery where small mechanical devices and robots must be carefully monitored in electron level in order to preserve machine functionality and efficiency. Therefore, the purpose of the lab is met and the hypotheses was supported, proving the quality and efficiency of the lab being

The first one is that I should connect myself to a vertex that is in the biggest component and purchases immunization. Since the probability of being infected is based off of expected value, I would have less than 1% chance of getting infected. The second way is that I try to make myself stay in the second-largest connected component.

When a secondary task is added the participant has not done before or is difficult, it task away attention or “ space” for the primary task.

In condition one the participant was asked to walk across the room (there and back) for a total of five trials.

654 Words | 3 PagesOur lab results on all three data table experiments had a percent error less than 5 percent. When examining these results I can be almost certain it was not systematic error due to the fact that a major percent error was not detected on every trial that was run in each of the three tables. With there being some percent error there is the possibility for random error which are from unknown factors, which could come from impact of outside forces like the air track interfering with the acceleration of the cart. Beings that this was the first lab for my lab partners and I were working there was room for slight personal errors with our use of the computer program as well as the lab equipment.

New meter ruler has high accuracy and the scale is clear enough so that people can take the reading easily. Next, it is preferred to use unstrectchable nylon string so that the radius will remain constant during the experiment. It is very crucial to maintain a constant radius in this experiment as it acts as fixed variable, supposed to be at the same length throughout the experiment.
