Advantages Of Online Edu Moodle
Introduction
Over the last few decades online education has vastly grown especially in the USA. Online
education has became popular among students of all ages. Universities have increased their
enrollment numbers by creating distance learning programs. Online University programs are a
convenient way for students to further their education and has the benefit of not having to go to a
geographical location. Students can access the courses without losing any quality of education that
is being taught in on site degree programs. Many Univiersities now offer online degree programs as
gives the opportunity to students who cannot for some reason attend regular hours further their
education.
Unfortunately many online courses per credit are actually more expensive than on site courses as

Moodle is a free and it's a learning management system. Some of the functions it provides are
assignment submission, discussion forum, files download, grading, online quizzes and also
announcements. Moodle has been around for over ten years and is one of the most popular open–
source Course Management Solutions available. As an online course software it is competent and
can be used to handle large classrooms. Moodle great advantage is is that it has all the functions
needed to run an online course and also can be customized to a large degree. Moodle offers all the
basic course elements plus fairly advanced elements. Because Moodle is open source, users have the
ability to customize nearly everything within their implementation if they know where to look.
Moodle requires a self–hosted installation, but building simple courses is fairly intuitive and
requires no coding knowledge. Moodle community is extremely active, any questions can be solved
via a quick search in the instructor forums. Moodle requires setup and maintenance

Advantage And Disadvantage Of Multicarrier Transmission
3.1 Introduction Multicarrier transmission, also known as OFDM is a technique with a long history
back to 1960that has recently seen rising popularity in wireless and wire line. In the recent interest
in this technique is mainly due to the recent advances in digital signal processing technology. The
International standards making use of OFDM for high–speed wireless communications are already
established or being established by IEEE 802.11, IEEE, 802.16, IEEE 802.20 and ETSIBRAN
committees. For wireless applications, an OFDM–based system can be of interest because it
provides greater immunity to multipath fading, and impulse noise, in eliminates the need for
equalizers, efficient hardware implementation can be realized using FFT techniques. ... Show more

The OFDM makes single–frequency networks possible, which is especially attractive for
broadcasting applications. 3.1.2 Disadvantages of OFDM Transmission: In the OFDM is more
sensitive to frequency offset and phase noise. In OFDM has a relatively large peak–to–average–
power ratio, which tends to reduce the power efficiency of the radio frequency (RF) amplifier. 3.1.3
Application of OFDM During the past decade, OFDM has been adopted in many wireless
communication standards networks, including European digital audio broadcasting system, and
terrestrial digital video broadcasting, and satellite terrestrial interactive multiservice infrastructure in
China. In addition, OFDM has been considered or approved by many groups are working in IEEE
standard, such as IEEE 802.11a/g/n standard network, IEEE 802.15.3a, and IEEE 802.16d/e. The
applications include wireless local area networks, wireless personal area networks and wireless
metropolitan networks. Currently, OFDMA is being investigated as one of the most promising radio
transmission techniques for LTE of the 3rd Generation Partnership Project (3GPP), International

Abstract– Big Data is a significant subject in modern times with the rapid advancement of new
technologies for example, smart phones, PC/laptops, game consoles, that all in some way store
information. Big companies require a place to not only store all the data that is coming in but to also
analyze it for specific purposes and at the fastest speed manageable. There exist numerous different
providers out there who provide this service, this paper will talk about one way the company Google
handles data using their own special made platform.
1. INTRODUCTION
In modern times, the amount of data being stored is terrifically large. Companies must deal with
such abundance of data on a daily basis in both storing and analyzing as fast as they can. ... Show

Velocity– Data streams in at unparalleled speed.
Variety– Data comes in several formats, including documents or audio or even email.
Management of Big Data is useful with how one handles the information. Ways to use the stored
information include, but not limited to, reduction of costs, time reductions, and making smart
decisions based on data results. [1]
A. UNSTRUCTURED
Defined before as information not so straightforward to interpret, instead of the easy to read data
that is the structured method. Unstructured data is generated in media like email messages,
PowerPoint presentations, Word documents and also media like JPEG images, MP3 audio files [9].
These results factor into whatever type of data analytics the company is after.
B. BIG DATA FINISH These results are vital for banking, retail, government, etc...., which use the
information to noticed habits of people inside and outside the company, who provided the info. The
information not only helps notice the habits of people, however, it also aids in figuring out trends
and what news is big from following data from social media. [1]

Using The Advanced Video Steganography Technique Essay
III. Problem Definition Present day transactions are considered to be "un–trusted" in terms of
security, i.e. they are relatively easy to be hacked. We also have to consider the transfer of large
amount of data through the network will give errors while transferring. Only single level of security
is present in the existing systems [10]. Now days, hacking activities are growing day by day and
hackers can easily hack important information and security is not sufficient to stop it. Though
security status increased at a higher level but the major drawback of new status of security is cost,
and became so costly. Hence we need better solutions which have good security level with lower
cost. These can be avoided by making use of our proposed system. The mechanism, which is used to
hide the information in the image files [11]. Here, to make the solution on the problems mentioned
above, we have proposed the Advanced Video Steganography technique. This advance method
consist of the combination of Compression, Encryption and Embedding technique, which is
mentioned in our proposed system. IV. PROPOSED WORK Video Steganography is the art of
writing hidden messages inside videos, in such a way that no one apart from the sender and intended
recipient realizes the existence of a hidden message. Steganography mostly uses repeating portions
of the Video files to embed the secret message. There are many techniques for hiding data in Video,
here we use one of those technique along with the

multimedia database and use to develop a multimedia system. Figure 1 gives the important
components of multimedia data mining. Figure 1.Multimedia Data Mining
Text mining Text Mining also referred as text data mining and it is used to find meaningful
information from the unstructured texts that are from various sources. Text is the foremost general
medium for the proper exchange of information [3]. Text Mining is to evaluate huge amount of
usual language text and it detects exact patterns to find useful information.
Image mining
Image mining systems can discover meaningful information or image patterns from a huge
collection of images. Image mining determines how low level pixel representation consists of a raw
image or image sequence can be handled to recognize high–level spatial objects and relationship
[14]. It includes digital image processing, image understanding,

Wi–Fi (ieee–802.11b) and Wi–Max (ieee–802.16e) have captured our attention. As there are no
recent developments which transfer data at faster rate as video information transfer taking lot of
time. This leads to introduction of Gi–Fi technology. It offers some advantages over Wi–Fi, a similar
wireless technology. In that it offers faster information rate (Gbps), less power consumption and low
cost for short range transmissions. Gi–Fi which is developed on an integrated wireless transceiver

So to have higher data transfer rate at lower power consumption we move onto Gi–Fi technology.
➢ The 802.11b and 802.11g flavours of Wi–Fi use the 2.4 GHz spectrum, which is crowded with
other devices such as Bluetooth, microwave ovens, cordless phones, or video sender devices, among
many others. This may cause degradation in performance. Other devices which use microwave
frequencies such as certain types of cell phones can also cause degradation in performance.
➢ Power consumption is fairly high compared to other standards, making battery life and heat a
concern.
➢ Not always configured properly by user. Commonly uses WEP (Wired Equivalent Privacy)
protocol for protection, though has been shown to be easily breakable. Newer wireless solutions are
slowly providing support for the superior WPA (Wi–Fi Protected Access) protocol, though many
systems still employ WEP.

60GHz on the CMOS . process. It will allow wireless transfer of audio and video data at up to 5
gigabits per second, ten times the current maximum wireless transfer rate, at one–tenth the cost.
NICTA researchers have chosen to develop this technology in the 57–64GHz unlicensed frequency
band as the millimeter–wave range of the spectrum makes possible high component on–chip

Artificial Neural Networks ( Anns )
Artificial neural networks (ANNs) are computational algorithms loosely based on the human
biological nervous system which work to model statistical data. An ANN "consists of processing
elements known as neurons that are interconnected to each other and work in unison to answer a
particular problem [, and] can be used in places where detecting trends and extracting patterns are
too complex to be detected by either humans or other computer techniques." Although recent in their
explosion in popularity, the underlying logic behind ANNs have existed for "nearly a half–century",
however due to the pervasive and ubiquitous adoption of powerful computational tools in our
contemporary society, ANNs have had a sort of renaissance, much to the avail of scientists,
engineers, and consumers.
The current cutting–edge in deep–learning and ANNs focuses highly on both their ability to model
and interpret complex data, and their ability to be put to scale due through optimization and
parallelization. The current framework for designing ANNs is one that is widely available, with a
myriad of tools facilitating their development. Python, C++, Google's Tensorflow, Theano, Matlab,
and Spark all contain a robust set of mathematical operations which necessitate ANNs. Due to the
algorithm behind ANNs, the models are inherently apt in "extract[ing] meaning from imprecise or
intricate problems". Speaking reductively, ANNs are data modeling tools which are trained on a
given dataset, and can

The Concepts Of Big Data Analysis Essay
Abstract–The important goal of this paper is to provide an overview on the concepts of big data
analysis. Furthermore the growing emergence and importance of qualitative data analysis in the field
of business intelligence and data science is broadly explained .It also marks out effective tools and
techniques used to obtain prominent qualitative analytic results on the global level. Moreover we
have concluded on the basis of comparison of the tools depending on various factors and parameters
by representing it on a tabular manner. I. INTRODUCTION Today, the data consumption rate is
tremendously expanding, the amount of data generated and stored is nearly imperceivable and
highly growing. Big data that is nothing but a large volume of unstructured or structured data that
runs in and out in to a business on daily basis. This big data is analyzed in order to achieve
prominent business growth and improved business strategies [1]. Every year there is at least 40%
increase in the amount of data growth on global level, leading to which companies have started
adopting new data analytic techniques and tools and also have stepped ahead moving their data
towards the cloud for their big data analytic requirements and for better analysis.[3][2] In big data
analysis it is not the amount of data that is essential but how efficiently we handle, process and
analyze it is the key factor. Big data analysis doesn't revolve around how much data we occupy, it
deals with how well you make use

Cognitive Signal Processing : Feature Estimation
Behavioural Signal Processing: Feature Estimation in Speech
Abstract
Human behaviour interrelates closely with the human beings' mental state. The behavioural
information reflects communication, social interaction and even personality. To build a bridge to the
human mind over engineering advances, an operational method, Behavioural Signal Processing
(BSP) technology, has been introduced, which aims to analyse speech–based human behaviour. The
main task of this project is the feature estimation based on BSP. In feature extraction, there are
numerous analysis modes, of which the Mel–frequency cepstral (MFC) represents the short–term
power spectrum of a speech signal. As MFC is about the power spectrum and requires Fourier

Moreover, behavioural research for psychological estimations deeply depends on cautious
evaluation of numerous observational indications. [5] Both the observation theory and current
experimental results state that significant other's behaviour is relevant with plentiful factors
including age, gender, education background, cultural background, life experiences as well as recent
mental and physical health conditions such as stress, illness, or disability. [3] Also, the affection
extent between intimate relationships matters much about how people act or communicate/speak. In
this project, the audio data is extracted from a dialogue in drama to simulate a marital discussion.
Behavioural Signal Processing
According to the main reference, "Toward automating a human behavioural coding system for
married couples' interactions using speech acoustic features", in this project, the self–reports of
observable behaviours can be extremely untrustworthy to some extent. Additionally, many of
speaking recognition algorithms centres more on demonstrating objective human behaviour, for
instance, the exact words, that is to say, what words or sentences people exactly say to their partners.

The speech signal is typically represented in electrical pulses that are amplitude modulated by the
envelope of the signal. In the CIS (continuous interleaved sampling) strategy (Wilson et al., 1991),
the speech signal is divided into a number of bands and the envelope of each band is extracted and
used to modulate the pulse trains. Speech/Voice is a pressure wave, which is afterward converted in
to numerical values in order to be digitally processed. Converting pressure wave in to numerical
values needs some hardware devices: a microphone allows the pressure sound wave to be converted
in to an electrical signal. A sampling at time intervals yields voltage values, and finally an analog to
digital converter quantizes each signal in to a specific number. Normally, a sampler and an analog to
digital converter are integrated in to audio card, where the basic stages of the signal processing are

Video Steganography: A Method for Providing Improved Security
I. Introduction
Steganography is the practice of concealing a file, message, and important information of any
format as text, image, audio or video within another file, message, of any format. Steganography is
the art of hiding the information in some other host object and it has been used since ancient time by
the people. In ancient time, secret information is hidden in the back of wax, scalp of the slaves, in
rabbits etc. The word steganography used from the past combines the Greek words steganos,
meaning "covered, concealed, or protected", and graphein meaning "writing" [1]
Steganography is the act of changing the digital media in a way that only sender and the intended
recipient is able to detect the message sent through it.
The following formula provides the description of the pieces of the steganography process [2]:
Cover Medium + Hidden Data + Stego Key = Stego Medium
In above formula, the Cover Medium is the file which is used to hide the hidden data, which may be
encrypted using the Stego Key. The resultant file is the stego medium which will, of course the same
type of file as the Cover Medium.
The Steganography method is different from the traditional cryptography method in the following
ways. Cryptography is the practice and study of secure communication. Steganography is the art and
science of covert communication. Cryptography is the practice of protecting the contents of a
message alone,

Personal Narrative Analysis
When I was in middle school I decided that I wanted an Ipod for listening to music in school. When
I got home I asked my mom if she could go on the computer to see what the prices for an Ipod were.
She looked it up on the apple store and told me they were anywhere from $200 to $400 depending
on which one you got. So for the next year I saved up enough money to get it. To this day I still have
that Ipod and it does not have one scratch unlike most people who have had theres given to them. I
believe that we should not beg for things; if we want something get it yourself.
The house I grew up in was rather different compared to most people. For the most part we had two
rules; "I want," "means no", and "if you want something work for it". These rules affected both the
way I thought of things and the way that I acted. The most noticeable for people was the way I act in
school. For the most part, I took things a lot more seriously than most of the other kids in my grade.
Additionally, my method of transportation is different compared to other people. Everyone sees

My mom grew up on a farm and did chores when she got home. Also, she did the dishes and had to
feed some of the animals. Additionally, if my mom wanted something she had to get it herself.
Ironically, I'm growing up just the way she did because we live in the same house she grew up in. I
have to work the same way she did. While my mom grew up on a farm, my dad grew up in the city.
He grew up in somewhat the same way my mom did excluding the farm. One of the most noticeable
differences is the way my dad went to college because he payed for it by himself. All in all, my
parents are like black and white compared to each other, but one thing that is in common is that they

Abstract– Big data is a significant subject in modern times with the rapid advancement of new
technologies for example, smartphones, pc/laptops, game consoles, that all in some way store
information. Big companies require a place to not only store all the data that is coming in but to also
analyze it for specific purposes and at the fastest speed manageable. There are many different
providers out there who provide this service, this paper will talk about one way the company Google
handles data using their own special made platform.

such abundance of data on a daily basis in both storing and analyzing as fast as they can. One such
company that not only store data is Google, they also analyze data from each user using their
product. The platform used by google for this database management called BigQuery, which runs in
the cloud and provides real time information. In this survey, the inner working of BigQuery is
glossed over to show how this platform manages to do the job it is supposed to accomplish.
2. WHAT IS BIG DATA
Big data is a vast amount of information, both structured and unstructured, unstructured is
information that is not simple to interpret by traditional databases and structured information is the
opposite, which is not too difficult to interpret data made form text or image. Structured or
unstructured, the main business of big data is categorized

How Dietary Tracking Is Important For People With Diet...
Dietary tracking is very important for people with diet related health issues, people trying to lose
weight, and just understanding and keeping everyday nutritional health. Many websites,
applications, and devices have dietary tracking databases that need the food to be inputted, and
selected from a large list (ChooseMyPlate, 2016; SuperTracker, 2015; SelfNutritionData, 2016;
Fontana, Farooq, Sazonov, 2014). This process can take 20 – 30 minutes for a diverse meal, which
requires users to sit down and input everything they eat. Eating foods with unlabeled packaging
makes it nearly impossible to track and input its nutritional value. With the Om Nom NoMonitor
food profiling technology, the user will no longer have to worry about unlabeled foods. The Om
Nom NoMonitor has software that can analyze a picture taken directly from a mobile phone using
technology similar to facial recognition, and then display statistics and log it into a digital food
journal (University of Salzburg, 2016). This product would be the best solution for this issue. The
Om Nom NoMonitor would be represented most accurately and commercially feasible by a
smartphone and downloadable app. The key aspects of this solution are Science and Technology.
Sciencetifically, the project must incorporate Food Science and Nutritional Science to catalog the
various qualities different foods possess and how that affects health. Technology is the major
element, as new software must be either created or adapted, along

NETWORK
Abstract: This paper presents an optimal and secure communication of real time data over a CDMA
based IP RAN network. In the process of data transmission, a new coding approach for security
enhancement and quality improvement based on spectrum utilization and antenna coding is
suggested. The traffic model is developed for image and audio data transmission over a wireless
channel, having an interference of AWGN noise with fading effects. An optimal spectrum sensing
approach for proper resource allocation is developed, and communicated using the secure WeP
protocol. The developed approach is evaluated for different communication parameters and
compared in comparisons to conventional modeling of CDMA system. The obtained results
illustrates an improvement in quality metrics for the developed system, in comparison to the
conventional modeling.

The iPod has enhanced the music industry in so many ways. It can be said that the iPod is the
greatest and most popular music playing device to have ever been made. If you own a iPod you will
know that you can get unlimited digital music, films and apps, some for free and some for a little
price. The good thing about it is that if you only like one song in the album you can buy just that one
song, instead of having to the whole album. The iPod is a MP3 product which allows you to
download the song of your choice from any site and still be able to play it through the iPod. An iPod
can be used for more than just music. It can also be utilized to play games, listen to audio books,
watch films, and recorded transcripts. Anything audio (and usually visual) can be played on the
iPad. There are many different models of iPods, including the "Classic", the "iTouch" and the
"Nano". All include individual features of their own. One of the iPod's great advantages is that it is
mobile and is used by many people on the move from businessmen to school children.
Even though the iPod may have some quite amazing qualities, it also has a severe downside, which

Working
First the analog signal from the input side is sampled as per the sampling rate as a result of it the
signal is now in the form of discrete signal.so to overcome the aliasing effect we use sampling
frequent which is twice the max frequency of the signal. Quantization process is is used to concert
this discrete signal to binary form after all this step the signal quantize as per the level of the
signal.at the output side decoding of this binary signal take place with maintaining the same level of
quantization in this way we will obtain the original analog signal.
DPCM
Definition
Differential PCM (DPCM) is more compelling then PCM as it figure this distinction and after that
transmit this little contrast motion rather than the whole info input sample. Since the distinction
between input tests is not as much as a whole info sample, the quantity of bits required for

transmission is diminished. As a result it reduces in throughput required to transmit the voice
signals. Utilizing DPCM can lessen the bit rate of any voice transmission down to 48 kbps.
Working and advantage:
The initial segment of DPCM works precisely like PCM so called derived function PCM. The info
sign is sampled at a constant sampling absolute frequency (two times the stimulation frequency).
Then these samples are modulated using the PAM appendage. At this item, the DPCM unconscious
process takes over. The sampled input signaling is stored in what is called

The Impact Of Music On The Music Industry
No one can deny that technology is actively changing the music industry. Production, distribution
and sales of music have been affected dramatically within the last 10 years along with artists,
composers, and technicians. Most of the changes have been great for consumers, but vastly negative
for professionals in the music industry, however a few artists have found ways to adapt to the
changing atmosphere of digitally downloaded music and use it to their advantage. We've seen music
change form from physical, tangible products like records and CD's to electronic single tracks stored
in an invisible cloud. Two major factors in this sudden revolution are online music stores
(specifically iTunes) and file sharing websites that allow music to be downloaded illegally.
Since the iTunes music store was introduced on April 28, 2003, gross music sales have plummeted
in the United States – from $11.8 billion in 2003 to $7.1 billion in 2012, according to the Recording
Industry Association of America (Covert). Counterintuitively, during that time consumers were
buying more music than ever. How is that possible? It 's because iTunes had made digital singles
popular and was selling them cheap. This would change the music industry forever. In 2000,
Americans bought 943 million CD albums (Covert), and digital sales didn't even make a dent in
comparison. But by 2007, those inexpensive singles overtook CDs by a wide margin, generating 819
million sales compared to just 500 million for the CD.

This Exhibition takes place within the Paley Center for Media, located on 25 W 52nd St in New

why and how his efforts prevented our Internet Culture and American media as a whole from being
widely censored. Without Aaron Swartz's contributions, American media as we know it would mere

The note holds, highlighting what we see is a clip of Swartz speaking at a panel. As this is occurring,
we hear a voiceover of a narrator, who narrates the upbringing of Swartz and several other details of
his life; mentioning small but interesting facts, such as his early experience with computer
programming and early graduation from high school to his future developments such as RSS and
Open Library. Accompanying this, we see a set of photos of Swartz consecutively appearing in a
collage, matching these times in his life. Lastly, the special begins to end on a still image of Swartz
smiling, we see the camera panning towards a closeup at a slow, nearly unnoticeable rate. Next we
notice a motivational, disembodied soundbite from one of Swartz's rallies explaining why he wants
to stop S.O.P.A. and the cultural cons that the bill would propose as well as his beliefs that
information was a humanitarian right, not a business. Next, we see the progression and success of
his numerous websites such as Demand Progress, which aided the efforts to prevent the SOPA and
PIPA act through the direct funding of pressure tactics against senators, to efforts of getting more
progressive senators elected. This success and progression is seen through a graphic displaying
annually rising statistics. Finally, we hear a bittersweet piano note ring in the background. There are
a few seconds left at the end as a moment of silence is requested, honoring Swartz's legacy, until we
see the screen finally fades to black. Continuing through the exhibit, we see that there is a non–
linear path to follow as one can turn left or right. We notice that turning left would lead into the
"Childhood" section of the exhibit, while turning right would lead into the "America without Aaron
Swartz" section. Turning into the Childhood section, we see the walls of this room are covered in a
childish space wallpaper that we'd expect from a boy genius.

The more statistics that is made to be had at the Internet, the greater proprietors of such records want
to defend themselves from robbery and fake illustration. Cheddad et al. [3] have presented that
Steganography is the science that involves communicating mystery information in the suitable
multimedia carrier, e.G., photo, audio, and video files. It comes beneath the idea that if the function
is visible, the point of assault is obvious, hence the goal here is constantly to conceal the very
lifestyles of the embedded statistics. This paper provides a today's review and evaluation of the
unique current strategies of Steganography along with some common standards and tips drawn from
the literature. This paper concludes with some recommendations and advocates for the item–
oriented embedding mechanism. The emerging strategies together with DCT, DWT and Adaptive
Steganography aren't too liable to assaults, specifically while the hidden message is small. This is
because they alter coefficients within the transform domain, hence photo distortion is saved to a
minimum. Generally those techniques have a tendency to have a lower payload compared to spatial
area algorithms. There are one–of–a–kind approaches to lessen the bits had to encode a hidden
message. Sarbavaidya

Audio Assets Definition
What are Assets?
"Assets are sometimes defined as resources or things of value that are owned by a company."
(1) Audio
Audio is sound that is within the acoustic range which is available to humans. An Audio Frequency
(AF) is an electrical alternating current within the 20 to 20,000 hertz (cycles per second) range
which can be used to produce acoustic sound. In computers, audio is the sound system that comes
with or can be added to a computer. An audio card contains a special built–in processor and memory
for processing audio files and sending them to speakers in the computer. Audio files are records of
sound that has been captured and can be played back. Sound is a succession of naturally analog
signals which are converted to digital ... Show more content on Helpwriting.net ...
There is also no compression involved. The digital recording is a close–to–exact representation of
the analog sound. PCM is most commonly used in CD's and DVD's. It has a subtype called Linear
Pulse–Code Modulation, where samples are taken at linear intervals. LCPM is the most common
form of PCM, which is why the two terms are almost interchangeable.
WAV
WAV is also known as Waveform Audio File Format. It was developed by Microsoft and IBM back
in 1991. Lots of people seem to assume that WAV files are uncompressed audio files, but that's not
always true. WAV is actually just a Windows container for audio formats. This means that a WAV
file can contain compressed audio, but it's not usually used for that. A lot of WAV files contain
uncompressed audio in PCM format. The WAV file is just a "wrapper" for the PCM encoding, which
therefore makes it a lot more suitable for use on Windows systems. However, Mac systems can
usually open WAV files without any issues.
AIFF
AIFF stands for Audio Interchange File Format. Alike Microsoft and IBM developed WAV for
Windows; AIFF is a format that was developed by Apple specifically for Mac systems back in 1988.
Also similar to WAV files, AIFF files can also contain multiple kinds of audio. For example, there is
a compressed version called AIFF–C and another version called Apple Loops which is used by

Compressing, Transferring and Storing Audio Data
Today's most popular solution for compressing, transferring and storing audio data is MP3
technology. There are similar technologies for sampling and compressing audio data but MP3
remains the most popular because it is versatile, high performing and flexible. MP3 as we know it
today, is the product of collaborations through the years by many organizations. If we had to narrow
down the most important people involved in it's development, the two most important names would
be Dieter Seitzer and Karlheinz Bradenburg. Initially, in the 1970s, Dieter Seitzer, a professor from
Erlangen–Nuremberg University was researching the problem of compressing audio data for
telephone line transmission. He brought together a group of students as well as other scientists to do
research and solve this challenge. One of his students , named Karlheinz Bradenburg, proposed an
idea of exploiting the mechanism of human hearing and its limitations. Later on, in his doctoral
theses, Karlheinz Bradenburg included algorithms that were later incorporated in todays MP3
technology. Most importantly were his method of scanning and removing sounds that were in
audible to humans. In 1988 the ISO convened and called for a standard in audio and video encoding.
This call created the Moving Picture Experts Group (MPEG). Contributions to the group came from
various corporations, research organizations and individual scientists. This increase of contributions
and collaboration from members of the MPEG

The Four Elements Of My Teaching Philosophy And Philosophy...
I believe that ``A tax on gained knowledge is to disseminate it by teaching," which leads to the
unlimited expansion of knowledge. My principle philosophy about teaching is that it is a holy
message to deliver knowledge to anyone who seeks it, and this concept should make learning an
enjoyable experience. My practical teaching philosophy mainly depends on four elements: {bf
knowledge}, {bf encouragement}, {bf contemplation}, and {bf excellence}. The acquisition and
ongoing quest for and to share {bf knowledge} is key for any successful teacher. The {bf
encouragement} of student interaction is necessary for success in learning, especially the
encouragement of a student's {bf contemplation} on how to expand their knowledge based on the
material and always be thinking about new ways to solve problems. This process and involvement
can only lead to academic {bf excellence}. I can contribute to the success and happiness of students
through the practical implication of the four elements of my teaching philosophy. My ongoing quest
for knowledge will allow me to deeply interact with the class materials and student, and
communicate with them on their level of understanding. This balance between the knowledge of the
instructor and knowing the students' needs will allow for the appropriate level of challenge to
maintain interest in the class. When first approaching a topic to teach, I keep the students aware of
the big picture or overall purpose of what they will be studying.

802. 11 Synthesis Essay
IEEE802.11n made numerous changes to the 802.11 wireless standards that greatly increased the
throughput as compared to earlier versions. 802.11n uses MIMO which is Multiple Input Multiple
Output (also known as Multiple Antennas). MIMO makes use of multiple antennae to create
multiple streams of communications between a transmitter and a receiver. The 802.11n amendment
also introduced changes in the physical as well as MAC layers to make marked changes in the
effectiveness of wireless networks. These changes included spatial–division multiplexing, space–
time block coding, and transmitter beamforming. Spatial–division multiplexing. This is the ability

So the transmitter can increase the output of the antennas in the direction of computers farther away
or where there are more computers to allow for better coverage or throughput and decrease the
output of the antennas in directions where there are obstacles. Other changes in 802.11n include: 1.
40 Mhz bandwidth (channel bonding) which can get data rates as high as 600Mpbs which is a ten–
fold increase as compared with 802.11 a thru g. 2. Frame aggregation – transmits multiple MAC
frames in a PHY packet. 3. Reverse–direction protocol – allows the ability to transfer control of an
air channel between stations. This is especially good if the receiver is moving and the transmitters
are trying to keep the best connection possible. 4. Support for Voice over WLAN and multimedia
streaming. This is especially important as more telephone calls go VOIP and more video/audio
content is available online. 5. The ability of access points to change between 20 MHz and 40 MHz.
This is good as the receivers for that access point changes. The access point can speed up or slow
down based on the receivers in its broadcast area. 6. Channel bonding – using two 20MHz channels.
This turns the two 20 MHz band into a 40MHz band even though the transmitter is not transmitting
at 40MHz. This is good to increase throughput for receivers that only communicate at the 20MHz

Spectral Band Replication in Audio Coding
Spectral Band Replication (SBR) is a novel audio spectrum recovery technology, it can greatly
improve the efficiency of perceptual audio coding compression, and thus more suitable for
streaming media applications with limited bandwidth. It will be widely used in the world of digital
broadcasting, the third generation mobile communications, multimedia downloads, video–on–
demand and other services. SBR use parametric coding technique that involves complex algorithms;
simply take a long time by the hardware circuit design. And this design cannot keep up with the
constant development of audio standards. In other words: When a new standard integration into the
decoder, it takes a long time to complete the new circuit design, the original method will no longer
have a market value. Be achieved only using the software in power consumption and cost
requirements are higher for portable applications with limited competition. With the increasing
complexity and diversity of multimedia signal processing requirements, hardware and software co–
design concept has been widely applied to the actual design. The two main reasons why Spectral
Band Replication can fit our needs are: First, SBR is capable of reproducing the high frequency
band by using the correlation information which transmitted along with the low frequency band.
Therefore, we can save the bits which were reserved for coding high frequency band without
actually lost the high frequency signal. Second, it is more

Steganography, The Most Efficient Part Of Steganography
INTRODUCTION
Nowadays, the use of the Internet is almost inevitable, as the use of Internet continually increases
providing information security is also very key important. One of the reasons cyber attacks are
successful is because the information acquired from the systems are usually readable/unencrypted,
attackers can access. This is where information hiding becomes necessary; it 's a branch of computer
science that deals with concealing the existence of a message. There are four primary sub–
disciplines of information hiding in an undetectable and/or irremovable especially in audio and data
i. Steganography ii. Watermarking iii. Covert Channels iv. Anonymity *Figure 1: Methods of
Information Hiding
For the purpose of this paper, I will be focusing on Steganography, which I believe is the most
efficient part of steganography. Unlike other Information hiding methods where the encryption is
usually detectable, steganography takes it further by hiding the message within mediums like
images, main it almost impossible to detect. The purpose of this paper is to explain Steganography,
how it works compared to other methods and show methods of application and types of
steganography.
WHAT IS STEGANOGRAPHY?
Steganography is the art of communicating in such a way that the presence of a message cannot be
detected; simply put "covered writing". The message is out in plain sight but Steganography hides
the existence of a secret message and in the best case nobody can see that both
