Wireless fan (high level design) report - Essay Example This document, once it is approved, serves as the basis for: The scope of this project is to architect, design and create Wireless fan. The fan has four switches one of them is turn on/off (A), and the others which are (B,C,D) to change the speed levels of the fan. So I have: The wireless has an exposed antenna. This antenna serves the purpose of boosting transmission of the trigger towards movement of the fan. The components would be light and not jammed because there is meager use of connecting wires. It is vital to note that the switches will possess an indirect link to the decoder. This is to enable the usability of switches. In addition, the switches will possess an angle of 90 degrees to the motor. This is to enable the compatibility of the switches to the motor fan. It is vital to note of the idea that the wireless fan system possesses two core components. These two components have more than a functional separation. The core parts possess a physical and functional separation between the sending and receiving components. This has a first antenna and a second antenna that link to transmit signals between the same. The decoder is segregated to send and receive signals through the system of antennae. The antennae have a relationship between the two links in a sense that the two signals shift between entities. Therefore, the decoder connects to the motor that rotates to trigger the movement of the blades. The system has four switches that connect to the four sections of the decoder. The decoder connects to the antenna and the LDE. In this sense, the antenna sends a signal to the receiving antenna. The antenna transmits a signal that triggers three levels of the decoder. The decoder, thus, transmits a signal to the motor that

Discuss the overall trend in postwar aggregate productivity in the US Essay

Discuss the overall trend in postwar aggregate productivity in the US - Essay Example labor has been averaging around slightly above one percent faster than MFP: from 1953-2012, labor productivity grew at an annual rate of 2.2 percent per year, and MFP grew at an annual average rate of 1.1 percent per year ().this projects a volatile economic growth rate annually. The volatility could be attributed to measurement error in estimation arising from both series. Getting an accurate measurement of these rates is a daunting task given the fluctuations in the rates market. Another reason stems from the fact that series have certain gas between then that cyclical. To illustrate this, consider when the MFP growth fell—in fact, took on negative values—during the recessions that started in 1969, 1980-81, 1990, and 2007 ().the negative values are an indication of how less optimal the inputs have become in yielding the expected returns. Besides, a negative MFP growth can also arise from variation in the utilization rates of capital and labor over the business cycle (). In the last 60 years the long-term mean growth rates of labor productivity and MFP have varied substantially in three episodes. In the initial episode, the 1950s through early 1970s, there was a high growth of MFP.MFP growth averaged at 1.7 percent per year from 1953 through 1972. In the next episode, from the late 1970s through early 1990s, there were lower MFP growth with an average of 0.5% annually. In the last episode, from the mid-1990s up to now, experiencing an intermediate level of MFP growth of 1.0%
