Nt1310 Unit 5 Exercise 1

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

1. I understand that the job of an Urban Teacher is a daunting task.It requires an individual with the capability to building strong student ethics , character and achievement Teaching requires passion and a desire to impart knowledge in students from all communities.

Wireless Routers is a wireless local area network (WLAN) that determine the next route of the packet should travel to the destination (Rouse, 2005). It converts the internet connection that was received from phone lines into radio signals and brings convenience to the portability devices that has built-in network card to gain the radio signals to get to the Internet connection (Switcher, 2015). Table 2 refers to the comparison of three models of wireless router.

Assignment 7. Go online and search for information about security threats posed by browser add-ins, such as Java applets and ActiveX controls. Note that most of these programs are small in size and downloaded onto computers over the Internet. Look for a specific example of a security problem resulting from such add-ins, and document the problem in a case study.

Quantitative risk analysis involves steps, calculations and tools to have a good analysis. The steps involve with this method from (wikibooks n.d) includes: assigning value to assets, Estimating potential loss per threat, Performing a threat analysis and Deriving the overall loss potential per threat. Firstly, in order to assign an accurate value to an asset, all tangible and intangible assets must be identified. For instance a company may have a server and to determine the value of the server, the important of the server to the company and the cost of losing server are factors that helps in determining the value for the server. Secondly, the potential loss per threat should be estimated. If a server is hacked, how much loss will it cost to the company? To know that, the Single Loss Expectancy (SLE) has to be calculated. SLE is the asset value (AV) times the exposure factor (EF). Thirdly, risk analysis have to be performed. In the case of a server being stolen, it has to be determine how many times in a year can it happen. To know this, the Annual Rate of Occurrence (ARO) have to be calculated. Also, the overall loss potential per threat have to be known. The overall loss that can be incur from a stolen server and the probability that a server will be stolen can be derived by calculating the Annual Lost Expectancy (ALE) which is annual rate of

Actually,you are required to comply with two different sections. The top chord must satisfy section 8.6.5.1 and the web components must comply with 8.6.5.2. I understand you’ve placed the sprinkler 2-ft away from the top chord that satisfies Table 8.6.5.1.2. One could argue that these are not structural members so 8.6.5.2.1.4 allows you to ignore them. Although that would meet the letter of the standard, it would not meet the intent. As required by 8.6.5.2.1.3, you need to be located away from the obstruction a minimum distance of 3 times the maximum dimension of the obstruction. That would be 9 in. away from the vertical web components and 6 in. away from the diagonal components. The 2-ft separation dictated by the top chord obviously complies

Question 2: determine the DWI components needed to complete the DWV system for the bathroom shown in figures below. The horizontal waste piping is 2 feet below the

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.

In lesson 1, I would still use my same warm-up problem, but as mentioned above, I would want to push the students to think deeper about the problem. I would accomplish this by asking probing questions to get the students to consider the problem from a different perspective. Also, by creating a more debatable perspective, the students would have a greater opportunity to defend their thinking with mathematical reasoning. This would also challenge the students who do well in math to think even deeper about a concept that may seem obvious.

Figs. 8(a-c) show the generated stator, rotor and total active powers respectively. Total active power is identical to the estimated power curve in Fig. 2. Fig. 9 shows the stator reactive power while the rotor reactive power is taken from the DC bus system. The RSC has large size with the lead power factor (Qs= -1.6 MVAR), otherwise, all lag power factors have smaller RSC size.

The control of active power and frequency in a power system is referred to as load frequency control (LFC). Stable operation of interconnected power system requires both constant frequency and constant tile-line power exchange [1]. An area control error (ACE), defined as a linear combination of tie line power and frequency deviations, is taken as the controlled output of LFC. LFC regulates ACE to zero such that frequency and tie-line power errors are forced to zeros. PID controller is widely used in LFC due to its simplicity but is gives long settling time and produces large frequency deviation [2]. In recent years, active disturbance rejection control (ADRC) developed by J. Han [3] and modified by Z. Gao [4, 5] has been proposed for the LFC controller [6-9].
