This discussion appeared after the denial of access to printouts of Facebook pages sent through the U.S. mail for the prison inmate.The complaint of this prison inmate was rejected by the court because it was considered that some inmate’s mail can be restricted for â€Å"legitimate penological interests†. Also, it was considered an isolated event.Reflection - I think that the court took the right decision because prisoners lose some of their rights when they do crimes so it is a punishment for their acts. Also, because these days many violent actions are happening due to the Internet, a restriction for access to such social networking for prisoners is appropriate.Student Name: - Course number and sectionCategory: Security PrivacyTitle: FBI warns users of malicious mobile malwareBy: Dara KerrPublished: October 15, 2012Summary - The article addressed the warning of the government’s agency FBI towards malicious mobile malware. The supposed malware is re lated to Android operating systems for mobile devices and includes Loozfon and FinFisher.  This event is not singular, because statistics show an increase in security reports of mobile malware. A measure against this threat was taken by Google, which included new security features for Android mobile OS.Reflection - The security and privacy of personal data have been challenging in recent years because of the development of technology. I am concerned about this phenomenon, and I think that maybe mobile makers should consider more to improve security issues, than other design features.Student Name: - Course number and sectionCategory: Cutting EdgeTitle: Stair-climbing wheelchair turns wheels into legsBy: Leslie KatzPublished: October 15, 2012Summary -  The article discussed the Japanese invention of a sensor-packed wheelchair with special features. This wheelchair can roll out and climb over obstacles and as well can turn a circle in tight spaces.

Signal generators also know as function generator or test oscillator Free Essays

string(96) " input is supplied into the 8bit counter which evaluate the input with an analog, \(Q5 to Q0\)\." ABSTRACT Signal generators also know as function generator or test oscillator, have come to be more popular and most used testing device for the engineers especially and also for the medical sector. Signal generator delivers an accurate calibrated range. It provides a signal that can be adjusted according to the frequency, output voltage, impendence, waveform and modulation. We will write a custom essay sample on Signal generators also know as function generator or test oscillator or any similar topic only for you Order Now It has been in existence and they are used in so many ways before time till present. An American inventor Nikola Tesla has conveyed electricity from one location to another in the form of signal and uses the same frequency. This report talks about the overview of a signal generator, how they do function using their applications and also describe to us their operating principles using the direct digital synthesis DDS, their types and designs. The Next page gives you a brief introduction about the early days of signal generator and how they are been used in those days. INTRODUCTION Before the Initiation of this device called signal generator which is around 1906 to 1920 are regarded to be the early days of radio, the only way for testing of new apparatus or electronic instrument was to use another similar device to create the signal, which was the case of new tools and modulation format in radio. During that time, this basic method of testing worked excellently with minimum percentage errors, but problem arises when there is a circumstance whereby they might be diverse devices under test. To solve this problem, there must be need for so many reference devices. One radio’s was picked which was used as a performance parameter and was measured which was now used as the standard or â€Å"golden radio† as it has been called. Even if they are expensive, a regular change in their functioning features either during a short time as a result of warming up or during a long time as an effect of continued use, and for this reason their will be reduction in their accuracy. The need for signal generator that can effectively used to test devices as the field of engineers must be to reduce this flow. However, we are going to explain the device â€Å"signal generator† in this report and also we will discuss about the operating principles, and also the things I have already mention in the abstract area. In this next page, we will be looking at the overview of this device signal generator.  ­SIGNAL GENERATOR (Outline and types) A signal generator also called a function generator or a text signal generator is an electronic device designed to perform a variety of operations which includes band pass filter characteristics, the response of amplifiers to frequency or fault tracing in many electronic equipment and circuits. â€Å"Signal generator is a tool widely used in fields such as industrial electronic instrumentation, medicine, production, communication and research†, (Alloca and Stuart, 1983). A signal generator is the stimulus source that pairs with an acquisition instrument to create the two elements of a complete measurement solution. In its various configurations, signal generator can provide stimulus signals in the form of analog waveforms, digital data patterns, modulation, noise and it may add known, repeatable amount and types of error (distortion) to the signal it delivers. Signal generator can produce the most types of waveforms or signal which are square waves, sine waves and triangular waves over a wide range of frequency. Coombs, (1972) declares that the frequency range of a signal generator maybe less than 1Hzto at least 1MHz. Some other type of signal generators, have the ability to produce pulse, trapezoid and ramp waveforms including the ones mention above. Therefore, there are many types of signal generator designed to a variety of uses which has much possible application meaning that one particular type of signal generator may not be suitable for all pur poses. Here are the two main type of signal generator Arbitrary waveform generator Function signal generator Below is a picture example of a typical function generator: ARBITRARY WAVEFORM GENERATOR Arbitrary waveform generators (AWG) are complicated playback system that delivers waveforms based on stored digital data that describes the regularly changing voltage levels of an AC signal. The arbitrary waveform generator can produce any kind of waveform you can think of. You can use many methods to create the needed output (from mathematical formulae to drawing the waveform). FUNCTION SIGNAL GENERATOR Function generators are more simple compare to arbitrary waveform generator. They generate simple signal in wave form and this signals are been produce by a circuit which creates the repeating wave which is usually a sine wave. They are most often use in process of designing or repair simples electronics. DESIGN OF SIGNAL GENERATORS Before the modern waveform generators were initiated, analog was the mode of operation. In some industries, analog refers both to the circuit technique used to generate signals and to the signal themselves. Functionality, economic feasible, and types of waveform needed have really change the design of signal generator in period of times, although the traditional analog signal generators still exist till date. The analog is a means to represent a material measure, for instance an indicator on a current meter (regulator), by a quantity whose measurement is known. Such measurements, do not really give the accurate result of a particular tool or device under test, as they are prone to having drifts in their working parts. Most modern signal generators are based on the digital technologies such as the modern function generators which uses a technology known as Direct Digital Synthesis (DDS) which are able to provide a wide range of signal or waveform. The DDS device are more like to generate analog signals via creating a digital output signal that is continuously pulsed by a clock signal and at last translating the digital signal to form an analog signal. Below is the experimental diagram of this process. The Method above, illustrate that the input is supplied into the 8bit counter which evaluate the input with an analog, (Q5 to Q0). You read "Signal generators also know as function generator or test oscillator" in category "Essay examples" The matching analog now is been verified with an already stored address which is the ROM (Read Only Memory) 256 x 8. As the counter cycles through the 256 different addresses, which the ROM has for each analog, the ROM counter now picks out a digital value corresponding to that address which sequentially represents the input. This information is then processed and outputs the 256 data points to the DAC (Digital to Analog Converter) which is the 8bit converter. The analog signal obtain is then shown as a waveform. An example of a generator that uses this method illustrated above is the 20MHz sweep function generator from BK Precision (model 4040DDS) image is shown below. According to BK Precision (2010), this sweep generator is a full featured DDS generator, the unit generate superb quality waveforms with a high signal precision and stability and it provides sine and square wave outputs over the frequency range from 0.1Hz to 20 MHz in one extended range. Most of the DDS generator today are dedicated instrument, simple and comfortable, and are at low cost from a few tens of dollars to tens of thousand of dollars. In the next section, we are going to look at how this device operates. OPERATING PRINCIPLES OF SIGNAL GENERATOR In this 21st century, most of the modern function generators use Direct Digital Synthesis (DDS) technology to generate output wave forms. BK Precision sweep function generator (model 4040DDS) happens to be among one of this generators. This section describes how DDS technology works. There are two fundamental ideas of DDS technology which includes: Producing an arbitrary waveform that can be in various waveforms or not assigned a particular value from a periodic ramp signals. Producing a digital ramp. First, consider producing wave function that can be in various waveforms or not assigned a particular value from a periodic ramp signal. To make this explanation more simple and understandable, imagine the ramp period (t) is greater than or equal to 0s (t ? 0), then lets call the recurring ramp function R(t) as shown in the diagram below. This ramp function R(t) as shown in figure 1 differs linearly or oscillate between 0 and 1 with period T. Now, suppose their is a new function F(t) that is defined on the interval 0? t ?1, in mathematical terminology, the domain of the function which is the values assigned to the independent variables of F(t) is the half-closed interval. Imagine to construct another wave function of period T which is similar to R(t) with the shape of F(t) and assuming again that the period is 4s using the diagram shown in figure 4, we will notice that as the time increases from t0 to t4, which is equal to one period, there is a sequence which implies that their will be a gradual rise in the function until t4, therefore calculating the corresponding value of each time and removing the integer part of it. For instance, tn= – . The calculation for t0 to t8 is shown in the table below using the figure 4 diagram. The illustration shows that there is a rise in the time value, in the sense that when one period is reach, it will start over again until another period is reached. This is how it works continuously for the defined time interval. This means that it resets after each successive cycle. On the other hand, the resetting of the time interval is carried out by a phase accumulator which is the first time interval that is the t1 = frequency. In the above example, the waveform that was created has a frequency of 0.25Hz and a phase angle of 90 that means the frequency is x360 As BK precision (2010) guild book instruct that to produce a digital ramp, as an alternative of increasing the time intervals by 1s, let the increment be in terms of ?, the phase angle, by the digital clock and for an N-bit counter, it will count from 0 to 2N – 1, then reset to 0 again. For example, let the value of be N = 4, which will be (24), therefore the counter result is 16 bits. When a signal is received, it will only match up to one of the bits frequencies and the waveform of that frequency will be generated. Lastly, the generated waveform might be displayed as a square or triangular signal using the control buttons on the device. This is made possible by including an operating amplifier (op-amp) in the circuit. Assume the received input signal was a sine wave, it can be converted to a square waveform; an op-amp acts as a comparator that gives and output signal of â€Å"1† only when the amplitude of the sine wave is greater than 0 and a â€Å"-1† when the amplitude is less than 0. According to Floyd (2009), this change was essential because digital data processing and transmission can be more effective and dependable than analog data and it’s of advantage when data storage is needed. FUNCTIONS AND APPLICATIONS Signal generators have hundreds of different applications and function that are suited for variety of use in many fields but in electronics measurement context, they fall into three basic types: Verifications Characterization Stress and margin testing VERIFICATION In the world of electronic and technologies, wireless equipment designers that are building new transmitter and receiver hardware must stimulate baseband I and Q signals (with or without impairments), to verify some wireless standards, a high performance arbitrary waveform generators can provide the needed low-distortion, high-resolution signals at rates up to 1GB/secs. CHARACTERIZATION This is a state whereby the newly developed digital to Analog converter (DAC) and the Analog to digital converters (ADC) must be systematically tested to determine their limits of undeviating, distortion and so on. STRESS AND MARGING TESTING Advanced signal generators, save the engineers hours of calculation by providing efficient built- in jitter editing and generation tools because engineers that works with the serial data stream architectures; commonly used in digital communications buses and disk drive amplifiers, need to stress their devices with impairment especially jitter and timing violations so engineers must characterize their emerging designs to ensure that the new hardware meets design specifications across the full range of operation and more. However, using this device, much difficulty in electronics and also field like the medicine can now be resolute easily. To design an assorted signal and a high speed low filter data, an arbitrary waveform generator can be used. They are specifically design for it. Radio frequency signals are used to achieve tests on radio transmitters and receivers. (Theraja and Thereja, 1959) Signal generators that are connected to oscilloscopes can be use in testing faults in electronic equipment and devices. In telecommunications today phones functions using signals, for example: the process, transmit and receive data. Devices for example: digital X-ray appliances, brain mapping system and advanced cardiology uses signal in most medical field today. CONCLUSION The modern DDS generators have some advantages and disadvantages of it depict that they help in solving solutions in various fields. Describing about the advantages of DDS, you discover that their frequency is tuneable with sub-Hertz resolution; their phase angle is digitally adjustable, as long as the clock is stable, they don’t go with the flow due to temperature changes or aging of components, addition of arbitrary waveform generator is not theoretically difficult and lastly they have simple design and low parts count which help to keep cost down. However, describing the disadvantages of this machine has to do with the negative aspect which is their output frequency is ? ? the clock frequency, their amplitude is also fixed that is; they need external circuitry to change, sine wave is sampled and not spectrally pure; distortion is present at that moment. But this disadvantages, does not cost more harm the technology is still the best and with more careful design in future, these advantages can me minimized. REFERENCES Floyd, L.

What would you want your roommate to know about you free essay sample

The first thing I would want my roommate to know about me is that I am terrified. The idea of leaving everything and everyone I have ever known is one that my head has not yet wrapped itself around. I have kept myself awake night after night, wide eyed, a stream of what-ifs marching around my mind. I have had moments where I wished time hadnt gone by so fast, and I could still be a dimple-faced elementary schooler, whose future is as distant as the unknown places on the other side of the globe. But along with this fear, is pure excitement. This scary idea of leaving home is also thrilling, I am anxious to learn and grow and be a part of the real world. I watched as my incredible sister left for college 3 years ago, and the idea of me leaving was so far off, but now it is the shocking reality that I must embrace. We will write a custom essay sample on What would you want your roommate to know about you? or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I will take on whatever is thrown at me, and I will enter each experience with open arms, even if those arms are trembling. Next, I want my roommate to know that I am a very open minded, loving individual. I love meeting new people and making new friends, so I do my best to be nice and inclusive towards every person I come across. I am upbeat and outgoing for the most part, though I do feel shy and self conscious at times, as I imagine everyone does. I think that being positive and working hard is all that one can do in hopes of progressing. I know, through experience, that maintaining a positive attitude can seem insurmountable at times, but I also know that these times pass, and we must pick up our broken pieces and stay strong. My roommate should also know that the only thing I am intolerant of is intolerance. This said, I respect the views and opinions of others, as I know we are all from different backgrounds, and have different beliefs. There isnt that much else that I would want my roommate to know about me, without meeting her first. This is because everything I know about myself comes from experiences I have had in one place, with a set of people from that same place. There is so much I have yet to learn about who I am, and these discoveries will come from being in a completely new place, with new people, and the opportunity to make my own decisions. I dont want to be defined by who I was in High School, not to say I am unhappy with that person, I simply feel that there is so much more out there for me to uncover.

Different Origins of Horse Breeds essays

Different Origins of Horse Breeds essays Have you ever wondered where different breeds of horses originated from? Many people probably dont care. But some people might find it interesting. Horses are bred for different structure, work and speed and come from all over the world. Horses are very unique in when and where they originated from. The Shire horse is the purest survival of an early type, which was spoken of by medieval writers as the 'Great Horse.' If this horse did not originate in England, this country at a very early date acquired a widespread reputation for producing it. Indeed, the English 'Great Horse' seems to have been a native development of that British 'War Horse' whose strength, courage and aptitude for discipline are spoken of in high terms by the Roman legions at their first landing upon these shores. The Clydesdale is a breed of heavy draft horse developed in and deriving its name from the district in Scotland where it was founded. The farmers of Lanarkshire, through which the River Clyde flows, evolved its type. The old name for Lanarkshire is Clydesdale. The exact origins of the Percheron have been lost over time. Some believe they are descendants of the original horses found in the region during the Ice Age. Regardless of its ancient beginnings it is known that at two points in history the native mares of the Le Perche region of France were mated with Arab stallions, first during the eighth century and later during the Middle Ages. By the time of the crusades the Percheron was widely recognized as outstanding for his substance and soundness, as well as for his characteristic beauty and style. The America Saddlebred horse was first mentioned in official government correspondence in 1776. It has been written that Paul Revere's mount for his famous ride was a Narraganset Pacer, a breed that was important in the development of the Saddlebred. American Saddlebred horses accompanied pioneers f ...

The Relationship Between Exchange Rates and Commodity Prices

The Relationship Between Exchange Rates and Commodity Prices Over the last several years, the value of the Canadian Dollar (CAD) has been on an upward trend, greatly appreciating relative to the American Dollar. A rise in commodity pricesInterest rate fluctuationsInternational factors and speculation Many economic analysts believe that the rise in the value of the Canadian Dollar is due to a rise in commodity prices stemming from increased American demand for commodities. Canada exports a great deal of natural resources, such as natural gas and timber to the United States. Increased demand for those goods, all else being equal, causes the price of that good to rise and the quantity consumed of that good to go up. When Canadian companies sell more goods at a higher price to Americans, the Canadian dollar to gains in value relative to the U.S. dollar, through one of two mechanisms: 1. Canadian Producers Sell to U.S. Buyers Who Pay in CAD This mechanism is quite straightforward. To make purchases in Canadian Dollars, American buyers must first sell American Dollars on the foreign exchange market in order to  buy Canadian Dollars. This action causes the number of American Dollars on the market to rise and the number of Canadian Dollars to fall. To keep the market in equilibrium, the value of the American Dollar must fall (to offset the larger quantity available) and the value of the Canadian Dollar must rise. 2. Canadian Producers Sell to U.S. Buyers Who Pay in USD This mechanism is only slightly more complicated. Canadian producers will often sell their products to Americans in exchange for American Dollars, as it is inconvenient for their customers to use foreign exchange markets. However, the Canadian producer will have to pay most of their expenses, such as employee wages, in Canadian Dollars. No problem; they sell the American Dollars they received from sales, and purchase Canadian Dollars. This then has the same effect as mechanism 1. Now that weve seen how the Canadian and American Dollars are linked to changes in commodity prices due to increased demand, next well see if the data matches the theory. How to Test the Theory One way to test our theory is to see if commodity prices and the exchange rate have been moving in tandem. If we find that they are not moving in tandem, or that they are completely unrelated, well know that changes in currency prices are not causing exchange rate fluctuations. If commodity prices and exchange rates do move together, the theory may still hold. In this  case, such correlation does not prove causation as there could be some other third factor causing exchange rates and commodity prices to move in the same direction. Though the existence of correlation between the two is the first step in uncovering evidence in support of the theory, on its own such a relationship simply does not disprove the theory. Canadas Commodity Price Index (CPI) In A Beginners Guide to Exchange Rates and the Foreign Exchange Market,  we learned that the Bank of Canada developed a Commodity Price Index (CPI), which tracks changes in the prices of commodities which Canada exports. The CPI can be broken down into three basic components, which are weighted to reflect the relative magnitude of those exports: Energy: 34.9%Food: 18.8%Industrial Materials: 46.3%(Metals 14.4%, Minerals 2.3%, Forest Products 29.6%) Lets take a look at the monthly exchange rate and Commodity Price Index data for 2002 and 2003 (24 months). The exchange rate data comes from the St. Louis Fed - FRED II and the CPI data is from The Bank of Canada. The CPI data has also been broken down into its three main components, so we can see if any one commodity group is a factor in the exchange rate fluctuations. The exchange rate and commodity price data for the 24 months can be seen at the bottom of this page. Increases in the Canadian Dollar and CPI The first thing to note is how the Canadian Dollar, the Commodity Price Index, and the 3 components of the index have all risen over the 2-year period. In percentage terms, we have the following increases: Canadian Dollar - Up 21.771%Commodity Price Index - Up 46.754%Energy - Up 100.232%Food - Up 13.682%Industrial Materials - Up 21.729% The Commodity Price Index has risen twice as fast as the Canadian Dollar. The bulk of this increase seems to be due to higher energy prices, most notably higher natural gas and crude oil prices. The price of food and industrial materials has also risen during this period, though not nearly as quickly as energy prices. Computing the Correlation Between Exchange Rates and CPI We can determine if these prices are moving together, by computing the correlation between the exchange rate and the various CPI factors. The economics glossary defines correlation in the following way: Two random variables are positively correlated if high values of one are likely to be associated with high values of the other. They are negatively correlated if high values of one are likely to be associated with low values of the other. Correlation coefficients are between -1 and 1, inclusive, by definition. They are greater than zero for positive correlation and less than zero for negative correlations. A correlation coefficient of 0.5 or 0.6 would indicate that the exchange rate and the commodity price index move in the same direction, whereas a low correlation, such as 0 or 0.1 would indicate that the two are unrelated. Keep in mind that our 24 months of data is a very limited sample, so we need to take these measures with a grain of salt. Correlation Coefficients for the 24 months of 2002-2003 Exch Rate Commodity Index .746Exch Rate Energy .193Exch Rate Food .825Exch Rate Ind Mat .883Energy Food .336Energy Ind Mat .169Food Ind Mat .600 We see that the Canadian-American exchange rate is very highly correlated with the Commodity Price Index over this period. This is strong evidence that increased commodity prices are causing a hike in the exchange rate. Interestingly enough, it appears that according to the correlation coefficients, rising energy prices have very little to do with the rise of the Canadian Dollar, but higher prices for food and industrial materials may be playing a big role. Energy prices hikes also do not correlate well with rises in food and industrial materials costs (.336 and .169 respectively), but food prices and industrial material prices do move in tandem (.600 correlation). For our theory to hold true, we need the rising prices to be caused by increased American spending on Canadian food and industrial materials. In the final section, well see if Americans are truly are buying more of these Canadian goods. Exchange Rate Data DATE 1 CDN = CPI Energy Food Ind.

Weve seen that the Canadian-American exchange rate and commodity prices, particularly the price of food and industrial materials, have moved in tandem over the last two years. If Americans are buying more Canadian food and industrial materials, then our explanation for the data makes sense. Increased American demand for these Canadian products would simultaneously cause an increase in the price of those products, and an increase in the value of the Canadian Dollar, at the expense of the American one. The Data Unfortunately, we have very limited data about the number of goods the American are importing, but what evidence we have looks promising. In The Trade Deficit and Exchange Rates, we looked at Canadian and American trade patterns. With data provided by the U.S. Census Bureau, we see that the U.S. dollar value of imports from Canada has actually went down from 2001 to 2002. In 2001, Americans imported $216 billion of Canadian goods, in 2002 that figure dropped to $209 billion. But by the first 11 months of 2003, the U.S. had already imported $206 billion in goods and services from Canada showing an increase year-over-year. What Does This Mean? One thing we have to remember, though, is that these are dollar values of imports. All this is telling us is that in terms of U.S. Dollars, Americans are spending slightly less on Canadian imports. Since both the value of the U.S. Dollar and the price of commodities has changed, we need to do some mathematics to find out if the Americans are importing more or fewer goods. For the sake of this exercise, we will assume the United States imports nothing but commodities from Canada. This assumption does not greatly affect the results, but it certainly makes the math much easier. Well consider 2 months year-over-year, October 2002 and October 2003, to show how the number of exports has increased significantly between these two years. U.S. Imports From Canada: October 2002 For the month of October 2002, the United States imported $19.0 billion of goods from Canada. The commodity price index for that month was 107.2. So if a unit of Canadian commodities cost $107.20 that month, the U.S. bought 177,238,805 units of commodities from Canada during that month. (177,238,805 $19B / $107.20) U.S. Imports From Canada: October 2003 For the month of October 2003, the United States imported $20.4 billion of goods from Canada. The commodity price index for that month was 119.6. So if a unit of Canadian commodities cost $119.60 that month, the U.S. bought 170,568,561 units of commodities from Canada during that month. (170,568,561 $20.4B / $119.60). Conclusions From this calculation, we see that the United States bought 3.7% fewer goods over this period, despite a price hike of 11.57%. From our primer on price elasticity of demand, we see that the price elasticity of demand for these goods is 0.3, meaning theyre very inelastic. From this we can conclude one of two things: The demand for these goods are not at all sensitive to price changes so American producers were willing to absorb the price hike.The demand for these goods at every price level increased (relative to former demand levels), but this effect was more than offset by the large jump in prices, so overall quantity purchased declined slightly. In my view, number 2 looks a lot more likely. During that period, the U.S. economy had been spurred by massive government deficit spending. Between the 3rd quarter of 2002 and the 3rd quarter of 2003, the U.S. Gross Domestic Product increased by 5.8%. This GDP growth indicates increased economic production, which would likely require increased use of raw materials such as timber. The evidence that increased demand for Canadian commodities has caused the rise in both commodity prices and the Canadian Dollar is strong, but not overwhelming.

How electronic medication administration has prevent medication error Essay

How electronic medication administration has prevent medication error - Essay Example Research reveals that eMAR (electronic medication administration record) minimizes medication administration faults, as well as other adverse occasions that are drug-related. With the help of eMAR bar code technology, physicians are capable of issuing correct medication at the right time to the appropriate patients (Chan, 2010). When nurses adopt this technology, patients’ medication orders appear on their chart electronically after being endorsed by a pharmacist. Nurses are also alerted by this technology in case the medication of a particular patient is overdue. Here, the nurse is supposed to scan the patients’ barcode on their wristband before proceeding to those who are on medication. If the two fail to match the appropriate medication order, one is issued with a warning indicating that the treatment is not right (Richardson, Thomas, & McDowell, 2013). Moreover, CPOE (computerized provider order entry) is an electronic prescribing practice that minimizes errors that are related to wrong transcription or poor handwriting. CPOE systems support drug prescription, alert on unsafe interactions, and allow physicians to make right medication decisions, which minimizes errors further (Ward, Froehle, Hart, Collins, & Lindsell, 2014). Therefore, it is true that electronic medication administration plays a vital role in inhibiting medical faults. Chan, S. (2010).
