The Application Of Hardware And Software

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

The purpose of this laboratory experiment is to “investigate how the vibrating source affects selected characteristics of the sound produced” (Giancoli, 2006).

The purpose of the experiment was to measure the effects of water on sound, as the density of the water is gradually increased by adding salt to the water. The experiment is based on the question: “How is sound effected by traveling through water of various densities?” The variables that were tested for were velocity, frequency, wavelength, period and amplitude of the sound. The group wanted to analyze several characteristics of sound to be able to observe multiple patterns that sound follows while it moves through water of increasing density.

Instrumental noise interfere with these simulated tinnitus sounds which are presented to the patient for diagnosing, which makes it difficult to properly diagnose the disease. So diagnosis will be easier if we can make use of the original

The setup of this experiment was fairly easy. Firstly, the temperature probe and the microphone were fixed to a ring stand and connected to the labquest; the labquest was itself connected to the CPU. Photo 1. From here, the logger Pro was launched. The temperature reading was recorded (20.7 o C in our case) and the microphone background reading was noted. As this point, the use of the temperature probe was over, and so it was disconnected from the labquest.

In Computer-related technology use in the high school physics classroom: A case study, the study was done with a focus on qualitative data, but the Force Concept Inventory (FCI) was administered to students and analyzed to add a quantitative component to the study (McClure, 1996). The copy of the Force Concept Inventory in the study shows that it focuses on material from the first half of a physics curriculum, such as Newton’s laws, kinematics, and uniform circular motion. The study Assessing the Effectiveness of E-learning Integration in College Physics in the Alamo Community Colleges District, also used the Force Concept Inventory to assess achievement. According to the researcher, “The examination was designed to probe all the dimensions that are central to basic college physics. It serves as the most reliable single index of students ' understanding of basic college physics” (Zhou, 2012). The researcher also talks about how since the FCI was created it has been validated multiple times. The consistent validity makes this measure great for measuring achievement but only for the content in the first half of a college physics course.While this is extremely useful it is not useful for my study.

Everyday all over the world thousands of dollars are wasted by people forgetting or not knowing that they have left their lights on. As a person who enjoys fixing problems I set out to design a product to fix this problem. Before I explain the things, I have researched I should probably explain my product itself. My product consists of a Raspberry Pi, light sensor, another circuit, and multiple components for visual purposes and for voltage reading. As most of the parts for this have already been made and are compatible with the Raspberry Pi, most of my product consist of costume made coding.

You are contemplating correcting the lack of knowledge of noise damage to people in your organisation and are contemplating the use of a training programme such as the one enclosed with this Module (i.e., Preventing Noise-Induced Hearing Loss).

A study by (Lambert, 1999) discovered that family historians are collectors, they collect information about people, places, names and stories. Our father Albert, was no different he lovingly compiled the family history because it gave him a perspective on our past and present. To give us an opportunity to learn about our heritage and build on it (Sharbrough, 2005, p. 64). Although it was common for people of his generation to research and record on paper. Albert decided to embrace computer technology, used the Osbourne 1 computer to record our story, and store it on a series of 5 1/4” floppy disks. The recent discovery of the computer and the disks has ignited curiosity from our scattered younger family members around the world about their contents. However, a report by a computer technician revealed the Osbourne 1 is not in working order but the data on disks may be recoverable. Also, when the family history is made accessible technological obsolescence issues will need to be managed. So that access to the document is available to all who want now and into the future.

The Raspberry Pi is a pocket-sized, lightweight and cheap computer that plugs into most TV or computer monitors. It is capable of everything that your usual computer would do. Such as Word processor, Spreadsheets, PowerPoint, games and can even play high definition videos. This credit-card sized computer was designed for all ages to use with aims that children all over the world could use it to study programming. Compared to a ‘normal’ computer, the price of a Raspberry Pi is considerably less – with them costing between $25 and $35 for Models A and B respectively (plus taxes and shipping fees)

As with several other industries during the last decade, the application of digital technology is becoming widely used in many prosthetic laboratories globally. Since the cost of dental laboratory work has become a major influence in treatment design, automation technologies could facilitate more competitive production in the area of dental technology. In recent years, dental restorations produced with the assistance of advanced computer technology systems have become increasingly popular due to its cost-effective production. Many dental corporations have access to CAD/CAM procedures, either in dental laboratories or in the dental practice. Some of the many benefits related with using CAD/CAM for dental restorations include the

In this activity, a Vernier microphone and a computer were used to know the speed of sound based on the graph and the values produced on the computer screen. The microphone was placed near the open end of a closed tube and a member of a group snapped his fingers near the tube to determine the speed of sound. The time interval was determined with the start of the first vibration and the start of the echo vibration. The noted time interval was the time for sound to travel through the tube and back. The speed of sound was computed by dividing the length of the tube by ½ of the time interval. The computed experimental speed was 355.47 m/s. The calculated percent error was 2.60% and it was not that large compared to the percent errors in the first activity. The causes of errors in this activity could be some mistakes in the computations particularly in estimating values, and probably the graph produced was not that perfect.

One of the most popularly used database models is the relational model. It was developed by Edgar Codd in 1969. This model provides a declarative method for specification of data and queries. In a relational model of a database, the database users directly state the information they want to be retrieved from it and abstract away from the responsibility of describing the data structures that are used to store data. A database that confirms to the relational database model is known as a relational database.

A WHO report from 2010 shows there are not enough trained people for screening in many Asian countries. The equipment they use now is not so efficient and user friendly for example they affordability of equipment, by even small district level centers, is an issue. (“A portable audiometer costs nearly Rs. 200,000 …”) The Power requirement is another issue days are lost during screening camps in villages with frequent power cuts. Also Training is required for operation, which limits usage. This device offers basic screening to identify potential individuals who are perhaps not even aware that they have a challenged hearing capability. In the case of children, many are not old enough to articulate that they cannot hear properly. While the device screens the ‘can’ from the ‘cannot’, it simplifies the total population that would need further investigation, reducing the stress on the

For agents to provide an excellent level of assistance, they need the greatest tools that you can provide them. The ‘tools’ we are referring too fall into three main categories:
