Download file to see previous pages As early as 1979, the United States government started handling complaints from people that were complaining about their television receivers being interfered with other signals from computers and radio. The arm that was responsible for receiving and processing these complaints was the federal communications commission (FCC). The FCC decided to establish regulations to guide them and system designers in order to curb future EMIs. There are various digital devices that are subject to the codes established by the FCC where a digital device is any unintentional device or system which produces and uses timing pulses in the excess of nine thousand pulses per second. This definition covers anything from a computer and a typewriter to laser printers (Fassbinder, 2002).
The regulations put a limit on acceptable emissions that can be generated by a digital device. A conducted emission is said to be the emission that exits a power cord of a device and the frequency is typically in the range of 150 kHz to 30 MHz the FCC compliance is required to be displayed on the device (usually a sticker on the back of the device) and devices that don’t meet this criterion cannot be sold in the United States. A violation of these regulations can lead the FCC to invoke their statutory powers and the violator can be jailed or fined heavily. The implication of this is that designing of a system that fails to keep in mind these standards might be cheap to produce but eventually expensive in the long run since it would be impossible to market a noncompliant device. It is therefore mandatory for the system designers to ensure that the electronic systems they develop are compliant (Keenan, 2003). ...Download file to see next pagesRead More

...?Discussions Black Box testing and White Box Testing Black-box test design treats the system as ‘inaccessible’, so it doesn't explicitly use knowledge of the internal structure of the system. There are many advantages to black-box testing like: 1. Ease of use: We simply work through the application, as an end user like will it work on windows platform or not. Will the Start, Exit and Minimize functions work among other functionalities; we came to know that Decimal Point overwriting and Last Function Buffer does not work. 2. Simplicity: We focus on invalid and valid inputs and ensure the correct outputs are received like testing functionalities like...

...scenarios and maintain a fairly low fault rate. These premeditated procedures and requirements bring about the idea of software testing, Validation and Verification It is different from software quality assurance, which incorporates reviews of the quality management system alongside a standard. While software quality control refers to control or management of products, software quality assurance, on the other hand, is a control of processes. This function checks whether or not a software project follows its premeditated procedures and processes, and that the project brings out the anticipated internal and external products (output) (Miller, DeCarlo & Mathur, 2004).

...recommended in such cases is elective caesarean at 38 weeks. Although she does emphasizes on the maternal consent in this regard. (Clayden, 2005) Note that the risk of getting HIV is high at 34 weeks of gestation. (European study, 1992) Although the benefits of choosing caesarean as the mode of delivery does have its merits, recent studies indicate that by doing so, the risks of postoperative complications were increased. (Maiques and Cervera, 1999) This is cause of concern as the patients with HIV already have lowered immune defenses, and by subjecting them to infection risks will in turn be counterproductive. Testing only women is another drawback, as it will lead to undetected cases and poor uptake...

...Education and Testing Standards EDUCATION AND TESTING STANDARDS GRACE SARKAR Order No. 416638 25 February EDUCATION AND TESTING STANDARDS Introduction The No Child Left Behind (NCLB) Law has qualitatively changed education in the United States of America. The standard of teaching has been made inversely proportional to the learning quality. When there is improvement in the standard of teaching, it inevitably leads to raising the volume and quality of learning. However, the process has not been very hunky-dory and changes inevitably leads to introspection and self-examination that leads to more improvements. The NCLB concentrates on starting with the teachers on developing the quality of education. The existing... ...

Education Testing

...Testing: Test Instrument Characteristics Teachers can choose from a wide variety of formal and informal room assessments. Formal assessments include norm-referenced and criterion-referenced standardized tests. Norm-referenced tests indicate how well a student compares to other students, while criterion-referenced tests show mastery over specific skills. For example, a norm-referenced test would note that Cyndy, a hypothetical middle-school basketball player, is the third best foul shooter on her team. A criterion-referenced test would indicate that Cyndy made 7 of every 10 free throw attempts....

.... The bias and the accuracy of the significance tests are provided below for each observation value. a. 10 observations The following is the results obtained for the Ordinary least squares regression performed on the dependent variable ‘y’ for 10 observations. From the above results, the bias for the YSeries is -0.331 and has a very low standard deviation of 0.008. The RMSE (Root Mean Square Error) is an absolute measure of the residuals. A low value indicates a better fit. The RMSE is relatively higher for the Intercept in comparison to the RMSE values for the XSeries and YSeries, suggesting that the latter two parameters exhibit a better absolute fit to the given data. The EDFs from the analysis is...

...optimum safety of the individuals working on them. The primary objectives of Systems Engineering is to deliver the systems with optimum practical effectiveness including reliability, efficiency, safety, quality, maintainability, scalability, upgradeability and cost effectiveness. Systems engineering is carried out in a structured process framework called the Systems Engineering Life Cycle processes and is defined by the ISO/IEC 15288 standard [Magee, Stan. 2005]. The process framework is presented in the figure below at a high level: Figure 1: The process framework of Systems Engineering (Source: Bahill, Terry A. and Dean, Frank F. Dec. 1994.)
