A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules …show more content…
These parts make up the sound waves and they travel through a medium which is the material that a wave energy travels through. On page 10 in Activity 2 we had to fill out the table on how to make a louder sound and we learned that to have a louder sound the compressions have to be larger and to increase the frequency the compressions also had to be larger. When we did the activity with the slinkies this was the case because when we had more compressions the sound was louder and the frequency increased. In Activity 1 on page 4 we learned that sound intensity is how much sound energy passes through a certain area in a certain amount of time as it spreads out from the source. Decibels are a unit of measure that indicates the relative intensity of a sound. In Activity 1 on page 5 when we were looking at the table it showed us that as the sound intensity increases the decibel increases because the decibel measured how intense the sound was. According to the chart on page 4 the decibels at a quiet library is 40 dB and the relative intensity is 1000, however if the noise source is some explosions then the decibels is 160 and the relative intensity is
A more detailed implementation description is shown in Figure~\ref{fig:block_HHC_shaw}. The components of the harmonic amplitude vector $Y$ are the Fourier coefficients of the measured vibration at the frequency $\omega$. The Fourier coefficients are obtained by integrating the demodulated vibration signal over one sampling period $T^s$. As for the control adjustments $\Delta u_c$ and $\Delta u_s$, they are obtained as the product of the components $Y$, and the inverse of the control response matrix $T$. The control adjustments are sampled and added to the control signal amplitudes of the previous time step, generating the current control amplitude vector $U_k$. The controller output is obtained by summing the modulated components of the control
Fig. 4 shows that the fit of this sum to the original data is robust. The annual and semi-annual frequencies are seen to reproduce or account for most of the pattern in the hospital admission data, indicating that asthma is very seasonal in El Paso. The fall peak occurs at the end of the rainy season; the spring during the severe dry season winds. Note amplitude and phase shifts associated with the 2006 July-August monsoon. The fall asthma peak occurred a month early, with extreme intensity.
Just a quick question – Do we have any customers at NCI that there data including (PII) stored on outside vendor servers or any type of systems? The questions triggers while I was working with Dr. Linehan secretary(Georgia Shaw) and she ask me to inquiry about it with the NCI Security Team or Engineering Team. Per Dr. Linehan Secretary, If answer is “yes” then Dr. Linehan may be convinced to buy his favorite Office Accelerator Cloud Version. We “may be” make a case for Dr. Linehan that other customers at NCI using third party vendor services to store their confidential data. If Dr. Linehan agree to store their data on vendor site than he will save lot of cost associated with ACT Software hosting at NCI. These are just a questions and everything
Premise: A team of three contestants answer a series seven questions by attempting to diffuse seven bombs before they explode. On each question, one contestant will have a certain amount of time to clip the wires that lead to the correct answers on each bomb. Each teammate must answer at least one question in the game. Successfully diffusing a bomb adds the money at stake for the question to the team bank. If a contestant clips a wire which leads to an incorrect answer or if time expires, the bomb explodes, sliming the contestant with a mystery substance (maple syrup, pesto, tomato sauce, etc.), and eliminates them from the game without adding any money to the team bank. Here’s how the game is structured for each bomb:
A honeypot is a fake system that contains servers to gather information on intruders who are trying to access the network; they typically exist in the DMZ zone of the network.
Spectrum sensing: Cognitive radio technology will enable the users to determine which portions of the spectrum is available and detect the presence of licensed users when a user operates in a licensed band. A CR user can be allocated to only an unused portion of the spectrum. Therefore, a CR user should monitor the available spectrum bands, and then detect spectrum holes. Spectrum sensing is a basic functionality in CR networks, and hence it is closely related to other spectrum management functions as well as layering protocols to provide information on spectrum availability.

The accompanying directions were formed for introducing Sun Java 1.5.0_08 (otherwise known as JDK 5.0 refresh 8). This may not be the most recent variant, but rather the one we are utilizing this semester. Note: Java is as of now introduced as a feature of Mac OS X, so no further establishment is essential for these machines. Guarantee, however, that you have the correct form by writing java - rendition to the unix order provoke; the reaction ought to be something like java adaptation "1.5.0_08" A run of the mill Java establishment takes around 400 megabytes of circle space. The establishment procedure reports the correct size.

Migration and population have played a massive role in defining the American lifestyle during the 18th and 19th centuries. One instance of this is through the different beliefs seen in contrasting ideals in the north and south. In the north, with much less of a reliance on agriculture, do not depend on the economic benefits of slavery as much as the south does. As a result, due to this, as well as the emergence of democratic philosophies, Americans, specifically those in northern colonies who didn’t rely on a cheap labor source, began to view such treatment as unequal and completely contradictory to the liberties granted in the Bill of RIghts. Additionally,
The snail like shape of the cochlear effectively boosts the strength of the vibrations caused by sound, especially for low pitches. When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube’s properties gradually change along its length, so the waves grow and then die away, much as an ocean wave travelling towards the shore gets taller and narrower before breaking at the beach.
The subject with type first and type second diabetes who does not receive standard care, comply with the prescriptions or poorly controlled metabolism regarded by the test physician.
For this audio presentation, I will be discussing the two parts of the stethoscope that is used for listening sounds, the diaphragm and bell. The diaphragm and bell are found at the opposite end of the stethoscope from the ear tips. The larger circular part is called the diaphragm, while the smaller circular part is called the bell. The process of how the stethoscope is used to listen sounds from the body involves the production of vibration of the flat surface of the diaphragm and bell as the sound wave hits it, then afterwards the sound travels through the rubber tubing in a process called multiple reflection (Layton, 2013). Eventually, the sound wave then reaches the other end of
