Abstract–This paper presents the original findings of an approach to adopting the bit–stream signal
to control a system. It contains the initial design process and simulations of a bit–stream based PID
controller to control and stabilize the output of a proposed Capacitive Power Transfer system in the
discrete time domain. Processing The simulated results use MATLAB's Simulink and illustrate the
potential performance of the controller. Compared against simulations of a similar nature in
continuous time, the bit–stream implemented system yields near identical results.

PID Controller
PID controller is one of the methods for temperature control and is widely used in process control
industry due to simple design and easy to implement in industrial [1]. PID controller consists of
three controllers, which is proportional (P) controller, Integral (I) controller, and derivative (D)
controller [2]. The equation for output of the PID control can be described as: u(t)=K(e(t)+ 1/T_i
∫_0^t▒〖e(τ) dτ+ T_(d ) de(t)/dt〗) [2]
Which e is the control error, K is the proportional (P) gain, Ti is the integral (I) time, and Td is the
derivative time. Figure 1 shows the PID controller design using operational amplifier (op–amp).

The Implementation Of Virtual Machine And Wireshark
Controllers: On behalf of experiments a Controller removes and adds the flow entries from the flow
table. Using OpenFlow: This research shows about the implementation of OpenFlow in software
defined networks. Main aim of this exp Install virtual machine and in the virtual machine install the
latest version of OpenFlow and then access the virtual machine by SSH. Dpctl is one of the utilities
that give control over the flow table of a switch and this is used for troubleshoot based on the study
of the flow table entries. Mininet helps to create a virtual network in the virtual machine and
Wireshark is a networking monitor tools with which a detailed study on the virtual behavior of the
network can be seen by displaying the results on timely basis. The experiment starts by creating
three hosts, an OpenFlow switch with three ports and a controller and dpctl. Configure the
OpenFlow switch to connect to a server and this server acts as remote controller. Now add flows
using dpctl and check the startup messages with the help of Wireshark. Verify the reachability and
then create a switch and this switch has a capability to learn about the source–port mapping.
Whenever a packet arrives, if the mac address of the device is associated with any port then that
packet is assigned to that particular port else the packet will be sent through out all the ports of the
switch. Now extend the study to two switches with each switch having a single host and configure in
a way, so that each switch

Disadvantages Of Fuzzy Logic

2.1 Fuzzy Logic Controller Fuzzy logic is a type of multi valued logic. It deals with approximate
reasoning rather than precise. Fuzzy logic derived from fuzzy set theory. Fuzzy logic was first
proposed by Lotfi Zadeh in 1965. Fuzzy logic has currently used in control theory, artificial
intelligence systems specially to control complex aircraft engines and control surfaces, helicopter
control, messile guidance, automatic transmission, wheel slip control, auto focus cameras and
washing machines, railway engines for smoother drive and fuel consumption and many industrial
processes. Fuzzy logic provide better results if we compared it with PID controller. Fuzzy set of

Haman knowledge and experience can be implemented using linguistic rules.
Non linear plants can be controlled.
It can also control fast processes.
Disadvantages of fuzzy control–
Human knowledge is often incomplete and episodic as compared to systematic way.
If the model is not known then it is impossible to achieve the stability of the controller system.
Sometime rules are mismatched and non coherent.
In complex operation fuzzification and defuzzification take long time.
Fuzzy expert systems–There are two famous type of system currently used in fuzzy logic
Mamdani fuzzy inference

The most common method is used currently is fuzzy inference system. In 1975, Professor Ebrahim
Mamdani of London University introduced first time fuzzy systems to control a steam engine and
boiler combination. He applied a set of fuzzy rules experienced human operators. The mamdani

Components Of Controller For Industrial Applications
PID controllers are the most widely–used type of controller for industrial applications. They are
structurally simple and exhibit robust performance over a wide range of operating conditions. In the
absence of the complete knowledge of the process these types of controllers are the most efficient of
choices.
The main function of PID controller is to minimize the error, A PID calculates the error between the
measured process variable and desired set point and then gives a corrective action to adjust the
process according to the set point and to keep the error as low as possible. The proportional term
gives reaction based on the current error; the integral value determines the action based on the sum
of recent errors and derivative value gives the reaction based on the rate at which error changes. The
combine action of these three parameters helps in generating a control signal to adjust the process to
the desired value. The equation of the PID is given as: u(t) =K_P e(t)+K_I ∫_(t_0)^t▒〖e(t) dt〗
+K_D (de(t))/dt (3.1)
Also the mathematical model of the PID controller can be represented by: (3.2)
Where:
u (t): is the output of PID controller, e (t): is the error signal and the input of PID controller, which is
the error between the desired input value and the actual output value,
K_P: is the proportional gain,
Ti: is the integral time
KI: is the integral gain
Td: is the derivative time
〖 K〗_D: is the derivative gain.

A Report On The Network
In this section, we will see the two networks constructed in Mininet and the flows running through
the network
Flows:
1. A total of 12 simulations were run through the network. Flows were generated between hosts
using the tool D–ITG.
2. Traffic generation:
D–ITG is used for generating traffic in the network. Random hosts and clients are selected for
sending traffic. To get sufficient delay in the network the link is used up to 100% in case of heavy
traffic, around 70% for medium traffic and 20% for low traffic. The receiver logs are registered for
each flow. Flows nature is UDP as UDP does not re–attempt to send a dropped packet. The packet
size is fixed to 1024 and number of packets send per second can be changed depending on the traffic
requirement.
The following tables give the details of each flow which were simulated for network 1.
The network was created in Mininet. It consists of 12 hosts and 8 OpenV switches. It uses the
external controller which is selected in Mininet python code.
Network 2 is constructed in Mininet. It is a partial tree structure with 11 switches and 12 hosts.
External Floodlight controller is connected to the Mininet network using python code. The
controller is set in a different Virtual machine.
Each KQI will be analyzed for all three algorithms on both the network.
1. Average Delay:
The best performing algorithm for high traffic flows is a latency based algorithm. It gives a
minimum delay of 1.845 sec which is 28% lower than the delay observed

Alice And The Video Games
Alice and the Video Games Alice, an ignorant little girl from Alice and the Wonderland tumbled
down the rabbit hole into a world of meaninglessness (IMDb); today, proponents of banning violent
video games are following Alice, stumbling over themselves into a pitfall of a lack of substantial
evidence and reasoning. An exemplary example of such a proponent is Eric Roberts, the
uncredentialed author of the article "Violent Video Games Produce Violent Behavior in Our Nation's
Youth and Should Be Banned". On top of making groundless claims against violent video games,
Roberts lumps in unrelated elements simply to appeal to pathos and vainly attempts to reel in his
far–fetched conclusions using a plethora of fallacies to back up his ... Show more content on
Helpwriting.net ...
In the latter half of his first argument, Roberts boldly claims "Violent video games equate to violent
behavior, especially in children whose brains are not fully formed yet" and "a game rated MA
(Mature) doesn't stop a kid from playing it," yet there is utterly no evidence supporting these poor
claims. In reality,according to the Entertainment Software Rating Board's official website, a
majority of parents check the video game rating before purchasing it for their child (ESRB). Robert
draws a hasty generalization in hopes that readers will gloss over such details and ignorantly agree
with Robert's meaningless and false claims.
A vast majority of Robert's argument is based around women being portrayed as helpless victims or
sexual objects. Drawing on sympathetic feelings, Robert equates violent video games to sexual ones
and generalizes them as a whole. While attempting to indirectly attack violent video games, he
utilizes the straw man fallacy to prey on a vaguely associated, weaker target: sexual video games.
He criticizes these sexual games to coerce compassionate support, a mere gaudy bauble for naive
readers to blindly listen to Robert's argument. In fact, Roberts gives absolutely no evidence to state
any link between violent and sexual video games, much less a link between how sexual video games
translate into sexist or aggressive behavior in the modern world. Rather,

Boeing states the following in a company newsletter released August 27, 2009:
Therefore, costs previously recorded for the first three flight–test airplanes will be reclassified from
program inventory to research and development expense, resulting in an estimated non–cash charge
of $2.5 billion pre–tax, or $2.21 per share, against third–quarter results. This charge will have no
impact on the company 's cash outlook going forward.
The comparison, effectiveness, and positive versus negative reactions to the use of these control
mechanisms are as follows:
Six Sigma affords the avoidance of a "hit and miss" approach by breaking into measurable bites an
entire chain of events leading to a problem, and then coming up with a corrective action (Roff, 2005,
p. 1). According to Bateman and Snell (2009, p. 582), the acceptable failure rate is "99.99966
percent level of accuracy." Although Six Sigma is a powerful control mechanism, it takes about 2–3
years from the time of implementation until its development is fully realized. It is a method that is
most useful to a company when it is tailored specifically to a company's processes. Feedback affords
the necessary communication between varying units and departments but

A New Energy Efficient Drives Using Permanent Magnet...
Nowadays, because of the fast evolution of electronic device, The recent developments in permanent
magnet materials, solid state devices and microelectronic have led to the appearance of a new
energy efficient drives using permanent magnet brushless direct current motors (PMBLDCM).
Brushless direct current (BLDC) motors are preferred as small horsepower control motors because
their efficiency is very high, the operation is in a silent mode, has a compact form, contains high
precision, low maintenance, Its structure is simple, and has a large torque, etc. Hence, it is
extensively used in national defense, aerospace, robotics, industrial process control, precision
machine tools, automotive electronics, household appliances and office automation [1]. However,
the problems are found in these motor for variable speed operation over last decades keeping
technology growth in power semiconductors, microprocessors, adjustable speed drivers control
schemes and permanent–magnet brushless electric motor production have been joined to enable
reliable, cost–effective solution for a wide area of adjustable speed applications. As the name
reveals, Brushless motors have no brushes and commutators. In direct current (brushed) motors, the
switching of current in coils of the armature is done using the combination of brushes and
commutators but in the brushless, the commutation process is achieved with the help of electronic
circuit, which diminishes the mechanic losses and the efficiency

Description Of The Electric Motors
1. Introduction The electric motors are widely used in model life. In task 3, it is required to design
an escalator in this task. To reduce the energy consumption, the control system should be designed
as working in two models, high speed or low speed when there is no people use the escalator. The
specific requirements are listed as below: 1. Suitable sensors are chosen to detect the number of
people in the escalator. 2. The escalator operates at a high speed mode when there is a person or
more in the escalator. The control voltage is 2.5V with no load connected to the generator. 3. The
escalator will change to low speed mode when the last person has left the escalator 5 seconds. The
control voltage is 1V with no load connected to the generator. 4. Mode 1: the motor will accelerate
from low speed mode to high speed model within 0.5 seconds. 5. Mode 2: the motor is able to
accelerate with a zero steady state error with minimum achievable rise time. 6. As the passenger in
the escalator are different, the system is able to work with no load and 5 Ω load. 2. Motor 2.1
Motor–generator set The motor and generator are connected in coaxial mode, as figure 1 describes.
Due to the specification (operating same in the situation of with and without load), the set point is
used. That is because that when the load changes, the voltage between the motor will change.
However, since the speed should be same in the condition of no load and 5 Ω load, the measured

efficiency and automated machines has increased in this globalized world. It briefly explains the
process followed by the industry to automate an entire plant. This project basically focuses on the
primary part of monitoring the parameters namely the temperature and the pressure. As the reaction
proceeds in the reactor the temperature and pressure of the same varies. The temperature and
pressure are measured using various temperature sensors like RTD and pressure sensors like pt100
respectively. Our aim is therefore to monitor them on HMI which is connected to PLC via a

MEGR 3171L Section L07
15 November 2014
Theory
PID controllers, also known as a proportional integral device controller, are one of the most
commonly used controllers in industry. A PID algorithm is derived from three coefficients. These
tuning parameters are the proportional, integral and derivative coefficients, which are adjusted per
device to obtain an optimal response.
The sole purpose of a PID controller is to control the desired output of the system via given
parameters at the input of the system. The manner in which this process is accomplished is by
measuring the output of the system. From the measured value, it is compared to the desired values.
A error of the output will cause an adjustment in the error signal, e(t). The schematic diagram of the
control is indicated with a plus/minus circle containing a cross. The plus/minus indicates whether
the value measured should be adjusted by adding or subtracting to the overall outgoing signal. If the
value is subtracted then the ultimate goal is a negative feedback. The opposite can be said for a
positive feedback. A positive feedback response will conclude that the system has an unstable
response. This error signal is directed back into the controller that will in turn generate an
accommodating control signal. This information can be understood further by reviewing Figure 1.

In 2015, K. Lenin et. al. [44] in their study "Modified Monkey Optimization Algorithm for Solving
Optimal Reactive Power Dispatch Problem" expressed that to reduce the real power loss,
modifications were required in local and global leader phase and a Modified Spider Monkey
Algorithm (MMO) was introduced. Paper also upheld that MMO is more favorable for dealing with
non–linear constraints. The algorithm was examined on the IEEE 30–bus system to minimize the
active power loss.

spider monkey optimization algorithm" in which a Lévy flight spider monkey optimization
(LFSMO) algorithm was proposed to solve the standard Optimal power flow (OPF) problem for
IEEE 30–bus system. The exploitation capacity of SMO was increased in the proposed algorithm.
LFSMO was tested over 25 benchmark functions and its performance was examined. It was found
that LFSMO gave desirable outcomes than the original SMO.
In 2017, S. Kayalvizhi et. al. [49] presented a paper "Frequency Control of Micro Grid with Wind

gains of PI controllers which helps in regulating the frequency of the micro grid. A typical micro
grid test system and a real time micro grid setup at British Columbia are the two case studies
considered, in which the frequency control is implemented. The implementation is done in two–step

other well–known algorithms and is

Disadvantages Of Process Control
Process control plays a crucial role in the chemical engineering industry. The aim of process control
is to have a safe plant operation, to attain the design product output, to obtain quality standards from
maintaining the product composition and to operate at the lowest production cost (Sinnott, 2005). A
process control system is there to eliminate or implement corrective actions on any disturbance that
occurs during operation of a process. Achieving these actions is done through using control loops
that measure specific process variables, compare a desired output to these variables and control
another variable to correct any deviation in the set–point of the system being investigated (Svrcek,
Mahoney, & Young, 2006).

Filing Systems May Not Be Electronic Or Manual
Filing systems may either be electronic or manual. An organisation will probably utilise a
combination of both systems, choosing the most suitable arrangement for the data that is to be
stored. Regardless of the type of system adopted, it should be effective and efficient, accessible,
accurate, reliable and user friendly. In a school setting, both electronic and manual filing systems are
used on a daily basis. To give an example; A manual filing system is used to store individual pupil's
confidential information. Each pupil has their own file; this is filed alphabetically and held in a
filing cabinet in the school office. The child's file contains confidential information such as date of
birth, address, family history and medical details. This filing cabinet is kept locked at all times to
ensure that children's information is protected and respected and only available for viewing by
authorised staff. An electronic filing system is used to record the school's financial transactions. This
is a very thorough and rigorous method for storing such important details. The system generates
orders; payments and reports that enable the head teacher and school business manager to monitor
spend and control budgets. This system is only accessible to the school business manager and access
is protected by a password. Filing systems may be used to store information that is readily available
to anyone to browse, such as telephone numbers of schools within the local education authority.

Term Control Essay
Clearly define the term control in the context of an organization. Give examples and lucid
explanation of the various types of control that can be used by a Manager. Why is the control
function so very important to the effectiveness and efficiency of an organization?
According to Robbins & Coulter, "control refers to the process of monitoring, comparing and
correcting work performances."
The control process is a three step process of measuring actual performance, comparing actual
performance against a standard and taking managerial action to correct deviations or to address
inadequate standards.
The process assumes that performance standards already exist. For the most part they do as the
organization would have set goals and ... Show more content on Helpwriting.net ...
A manager who has responsibility for cleaning would walk around to check the work done by
frontline staff and assign persons to areas not completed. Another example would be on an assembly
line where the manager can see the items before they are completed and correct any defects and
make any adjustments before the products are released for distribution.
Feedback control is the most popular type of control and as the name implies it relies on feedback.
With this concept control takes place after the activity is done. An example of this would be the
Toyota recall situation where based on feedback from customers (in the form of complaints), the
company sought to correct the problem after the product had reached the consumer. With this type
of control, there can be significant damage or wastage which can come at a high cost. However,
feedback control does have some advantages as it gives the manager valuable information or insight
into how effective the planning was. The manager can compare actual performance to planned
performance. If the variance is minor then it can be said that performance was on target. However if
the variance is major then the manager can use that information to implement or update his plans as
required.
The control function is therefore very important to the effectiveness and efficiency of an
organization. As the final step in the management process, control

Introduction
Technical Analysis Ralph Langner's article on the Stuxnet worm discusses the hardware, distribution
and targets of the attack. He also goes into detail regarding the outlook of future attacks and what we
can do to prevent them. The Stuxnet attack was not executed to steal or erase information. It was
carried out to physically destroy a military target; Iran's Natanz nuclear facility. The attack was
aimed at industrial SCADA controllers and was a stand–alone attack. It was not an attack that
required access to the Internet. The attackers relied on local networks and USB drives to carry out
the attack. ... Show more content on Helpwriting.net ...
This allowed the worm to be recognized as a device driver and to not be rejected by the Windows
operating system. The early version of the worm functioned as a man–in–the–middle attack. It sat
between the engineering software and the Siemens controllers for the input and output valves
feeding into each centrifuge. The worm would accept commands from the engineering software and
give false responses to indicate that these commands were being processed by the controllers. In
reality, the worm was regularly allowing the centrifuges to be over–pressurized, which had the effect
of causing the centrifuges to wear out and break more quickly. The later version of the software was
much more crude. It would take over the centrifuges and refuse to acknowledge signals from the
engineering software while an attack was active. The attack operated about once a month and
worked by slowing down the centrifuges and then spinning them back up to past their normal full
speed. This would cause damage as the centrifuges passed through what was known as a resonance
speed, which would destabilize the rotor. Stuxnet managed to increase the rotor speeds at Iran's
Natanz nuclear facility from a normal speed of 63,000 rpm to 84,600 rpm. The worms were
carefully designed so that it would not be obvious to someone in the facility that their mechanical
systems were being sabotaged. For example, the worm would randomly affect different centrifuges

The World Will Have A Generation Of Idiots
"I fear the day technology will surpass our human interaction. The world will have a generation of
idiots." Albert Einstein's words describe a time where people are more focused on a virtual version
of themselves than real human interaction. Some may argue that this time has already come, and
some say this time will be upon us soon. The inevitable growth of video games will lead to children
whose lives are dictated by video games. From mobile apps to consoles, video games have taken the
world by storm. They have grown to become the pastime or even profession of players all around
the globe. Professional gamers compete in games such as Call of Duty, Dota2, and League of
Legends in international or domestic tournaments with prize pools reaching over a million dollars.
The International, the largest gaming tournament in the world, holds a total prize pool of over ten
million dollars. This tournament is so popular that within an hour of being available, the tickets sold
out. Gamers compete in teams that sometimes hold members from many different countries.
Becoming a world–class gamer takes countless hours of practice just like any other sport. Although
many athletes may consider gaming to be more of a past–time because its lack of a physical activity,
gamers have to train their reflexes and hand–eye coordination to very high levels. Gaming has
evolved into a wide market and certain people are taking advantage of its opportunities. For
example, a youtuber named PewDiePie

Permanent Magnet Brushless Direct Current Motors
Permanent magnet brushless direct current motors Nowadays, because of the fast evolution of
electronic device, The recent developments in permanent magnet materials, solid state devices and
microelectronic have led to the appearance of a new energy efficient drives using permanent magnet
brushless direct current motors (PMBLDCM). Brushless direct current (BLDC) motors are preferred
as small horsepower control motors because their efficiency is very high, the operation is in a silent
mode, has a compact form, contains high precision, low maintenance, its structure is simple, and has
a large torque, etc. Hence, it is extensively used in national defense, aerospace, robotics, industrial
process control, precision machine tools, automotive electronics, household appliances and office
automation [1]. However, the problems are found in these motor for variable speed operation over
last decades keeping technology growth in power semiconductors, microprocessors, adjustable
speed drivers control schemes and permanent–magnet brushless electric motor production have been
joined to enable reliable, cost–effective solution for a wide area of adjustable speed applications. As
the name reveals, Brushless motors have no brushes and commutators. In direct current (brushed)
motors, the switching of current in coils of the armature is done using the combination of brushes
and commutators but in the brushless, the commutation process is achieved with the help of
electronic circuit, which

Table Controls at Bellagio Casino Resort
Controls at the Bellagio Casino Resort
Purpose of Case
The Controls at the Bellagio Casino Resort case was designed with several purposes in mind.
First, it illustrates a control system that is dominated by action and personnel controls, rather than
results controls. The analysis of this system leads to insights about some of the factors that limit the
feasibility of results controls.
Second, the case can lead into a discussion of what is meant by the term "tight control." The case
presents an excellent example of the application of tight action controls in the table games areas of
the casino.
Finally, the case can lead into a discussion of the meaning of what auditors refer to as "internal
control," which is a subset of the ... Show more content on Helpwriting.net ...
Another problem that casinos face is "skimming." Skimming means that money is taken from the
casino, such as cash from the cage or counting room often requiring cover through forged
documentation and changed audit trails. This problem can be used to lead into a discussion of
internal control and the ways in which cash is controlled in the casino. The two major purposes of
internal controls are (1) to safeguard assets and (2) to ensure reliability of the financial records. In
the area of cash, the casino maintains imprest cash balances to safeguard the cash and chips; this
means assigning individual responsibility for a certain amount of money. And they have elaborate
procedures to ensure that the financial records are reliable (e.g., multiple approvals of transactions,
checking of audit trails, multiple reconciliations, and trend analyses), some of which are described
in great detail in the case.
Do these procedures prevent skimming? The answer is a tentative yes. The controls are effective
against skimming unless collusion is involved, which is a frequent limitation to internal controls.
Weakness of Results Controls
Assignment Question 2,
. Results controls are simply not feasible for control over the dealers because results are not
measured until the 24–hour drop procedure is complete, and during that period more than one dealer
has worked at a table. It would be possible to measure dealer productivity by keeping track of deals
per hour,

Types Of Conventional Pid Controller
Conventional PID controller is one of the most widely used controllers in industry, it have remained,
by far; the most commonly used in practically all industrial feedback control applications. The main
reason is its relatively simple structure, which can be easily understood and implemented in practice.
On the other hand the recent advancement in fractional calculus has introduced applications of
fractional order calculus in control theory. One of the prime applications of fractional calculus is
fractional order PID controller and it has received a considerable attention in academic studies and
in industrial applications. Fractional order PID controller is an advancement of classical integer
order PID controller. In many cases fractional order PID controller has outperformed classical
integer order PID controller. In the field of automatic control, the fractional order controllers would
lead to more precise and robust control performances. Although it is reasonably true that the
fractional order models require the FOPID controllers to achieve the best performance, in most
cases the researchers consider the fractional order controllers applied to regular linear or non–linear
dynamics to enhance the system control performances.
In this chapter, the design of fractional–order PID controller is considered in order to minimize
certain performance indices such as integral square error. An artificial bee colony (ABC) algorithm
is used to tune the parameters of FOPID controller,

Apollo 13 Case Study Apollo 13 has experience a major malfunction which changes the mission
from landing on the moon to a spacecraft that is now is in a desperate struggle to return to earth with
the crew alive. The team work needed to achieve this is substantial and many of the staff at mission
control center will in some degree be a leader. Aside from Gene Kranz, one of the first people to
emerge as a leader and take control of the situation is Sy Liebergot. His review of the data coming in

Kranz. His level of expertise appears to be very respected by Mr. Kranz and the whole control room
though he does not allow this to the point of taking advantage and taking over the control room,
rather he uses his knowledge to be seen as a servant leader. Sy also uses his technical skills as he is
assessing the situation and what it means to the functionality of the space craft. When asked by Mr
Kranz what is going on, Sy first takes on a Autocratic type role and explains the situation to Mr.
Kranz, He is absolute in what he is saying but is still puzzled by the situation. Sy then transition to a
Joint decision role as others in the control room give there in put to the situation and finally ends up
with in a Consultation role as everyone in the control room has a better understanding about the
gravity of the situation the space craft is in. As the situation with the space craft is becoming clearer
we can see that Sy's role is very much task orientated as he has very limited direct conversation with
the space craft. He is more concerned in evaluating the data and working on a solution to the
situation. His emergence as a leader was out of dedication to the project, not to say he did not care
for the men in the craft, but by his nature in this situation he was task driven. The lines of
communication in the control room appear to be very direct. When Mr. Kranz asks you a question,
you respond directly to him.

Violent Video Games
Video games suck children into an alternate universe of violence. Many children play violent video
games without being aware of the problems they are creating for themselves. Such as being placed
covertly in an unhealthy situation physically, mentally and socially. However, it is good to expose
kids to technology, but it seems that many of these video games are quite violent and there is a high
possibility that these games lead to behavioral problems and isolation issues. Many of these games
include guns, grenades, knives and a number of other weapons. They are played from the player's
perspective, allowing the child to think that the screen is the view from their eyes and they are
shooting from the gun. Therefore when a child plays they get an odd satisfaction when shooting at
others, whether it be aliens, zombies or people. This feeling of satisfaction should be considered
inhumane. The average child is enrolled in sports or activities, giving them the opportunity to stay
physically healthy. That is all taken away when a child refuses to participate because of an addiction
to video games. Becoming unfit is what happens when most children develop bad habits. Slouching
is a great example, as a wide variety of kids are prone to the unhealthy yet comfortable position.
While playing video games for long hours, a child tends to turn to slouching, straining their neck
and discomforting their spin. This makes a child prone to the unwanted possibilities of having

Analyzing Networked Control Systems For Network Induced...
Abstract–Networked Control Systems (NCS) are the control systems in which the control loop is
connected through a communication channel. There has been an increased attention to the use of
Network Control System (NCS) in recent years because of their cost effective and flexible
applications. But one of the major issues that need to be studied and solved in NCS is the delay of
the data transmission which occurs throughout the communication network in the system and thus
degrades the control system performance and also causes the system instability. This paper basically
presents an analysis of network delay in NCS. In this paper, we have designed a model of delay
control system for network induced delay using the simulation model of network control system
delay and thus analysed the effect of network delay on the performance of the control system. The
TrueTime toolbox of Matlab/Simulink is used for simulating the NCS model.

3.1 PID Controller
3.1.1 Introduction
The most commonly used type of controller for many applications in industries is the PID controller.
It owns very simple structure and has strong performance across a wide range in the condition of
operation. PID controllers are the most suitable type of choices if there is no complete knowledge of
the system.
Minimizing the error is the most important function in PID controller. In which the controller

result in, a correct value of controller parameters according to the set point was given and also the
error remains low as much as possible. The response obtained by the proportional term is dependent
on the

Bureaucratic control hinders innovation and inhibits rapid change. For this reason bureaucratic
control should be combined with clan control.
Clan control
According to 'Bartol et al' clan control uses values, beliefs, traditions, corporate culture, shared
norms and informal relationships to regulate employee behavior and facilitate reaching of company
goals. Clan control builds commitment to organizational objectives by making employees willing to
face change. This replaces bureaucratic control's emphasis on rules and regulation.
For this reason clan control is needed with firms such as this with routine jobs. So in future changes
can be made such carrying different stock or more flexible duties for everyone. This will also reduce
labor costs as a person can do more then one task. Since there is increased emphasis on clan control,
the plant firm can improve productivity and reduce costs.
ASSESING CONTROL SYSTEMS
To make sure controls are facilitating change and innovation and improvement in the business
control systems need to be monitored to ensure they get expected results if problems such as the
following are present the control system will need to be looked at carefully.
Negative attitudes

Implementing of controls can lead to negative attitudes if controls don't meet the business
requirements or are poorly designed (Greenberg and Strasser 1986).

Electrical Motor Control II Project
Electrical Motors Control II Project The class I am now taking is Electrical Motors Control II.
Motor controls. A motor controller is a device or group of devices that serves to govern in some
predetermined manner the performance of an electric motor. A motor controller might include a
manual or automatic process for starting and stopping the motor, selecting forward or reverse
rotation. This project was put together by me, Olen and Melvin. Constructing a motor control panel
consists of many factors, such as; meeting the customer's specifications, desired operations, state
and local regulations. Every electric motor has to have some sort of way to control it. The motors
will have various ways to be started, stopped, reversed, and even ways to control the speed of the
motors. These features can be complex depending on the task that the motor will be performing. By
being able to do these things with the motors in various ways, helps make the task at hand a much
simpler and less time consuming process. Allowing workers to get their job completed more
efficiently. In this project that we were instructed to build we started with 240 volts AC power. We
ran from the main three phase power to three fuses, then to our starter and overloads then onto our
first motor. We repeated the process of Motor 1 for the second motor as we ran to three different
fuses than that of the first motor. When then ran from the fuses to a transformer to step the voltage
down. From the transformer we

salimnitk@gmail.com Abstract: – SEDC motors are used extensively in industrial variable speed
applications because of most demanding speed–torque characteristics and are simple in controlling
aspects. This paper presents an implementation of internal model control (IMC) for speed control of
separately excited SEDC motor based on LabVIEW. A mathematical model of the process has been
developed using real plant data and then conventional controller has been designed. A comparative
analysis of performance evaluation of controller has been done. Key–Words: – SEDC Motor, IMC,
LabVIEW. 1 Introduction DC motors are widely used in industrial applications, robot manipulators
and home appliances, because of their high reliability, flexibility and low cost, where speed and
position control of motor are required. This paper deals with the performance evaluation of internal
model control method with a clear objective to control the speed of separately excited DC motor. In
this paper, Speed of a SEDC motor is controlled using IMC. Separately excited DC motors are
highly versatile and flexible in aspects of speed control. The basic property of separately excited DC
motor is that speed of separately excited DC motor can be adjusted by varying its terminal voltage.
Therefore, the separately excited DC motor control is better than other kinds of motors. SEDC
motor is a highly controllable electrical actuator

Active vs. Passive Magnetic Bearings
Introduction
A magnetic bearing is a type of bearing that holds up a load using magnetic levitation. Scientists
first discovered the magnetic effects in magnetic minerals in 500B.C. In the late 20th century,
scientists began developing ways where this magnetic effect could be implemented into a bearing,
creating magnetic bearings. Today, magnetic bearings can be found in many applications where no
physical contact is required or extreme environmental conditions exists, including very high and low
temperatures. Magnetic bearings also offer higher running speeds, efficiency, longer machine life
and lower operating and maintenance costs due to being virtually maintenance free.

The responsibility of these sensors are to measure the deviation from a reference position. Inductive
sensors are comprised of soft–magnetic cores on stators and sensor targets on rotors. The values of
inductances of sensor coils wrapped around the cores are used to estimate the rotor position.
Although their readings can be affected by stray magnetic fields from AMB actuators, these sensors
are often easier to use than eddy–current sensors. This problem can be avoided for radial sensors by
using two diametrically opposite sensor heads in differential connection. This cannot be said,
however, for axial sensors. Axial sensors must be located close to the axial actuators, where the stray
fields are higher, in order to minimize changes of the actuator operating gaps caused by differences
in thermal expansions of the rotor and the stator.
An actuator is a unique type of motor that is solely used to regulating and moving a component or
system of the component. This type of motor uses electric currents to high fluid pressure to air
pressure. Active magnetic bearings are used in certain applications as actuators for applying a stable
force on a spinning object such as a shaft. Actuators used in an active magnetic bearing system
consist of the power amplifier and an electromagnetic coil to produce a stable motion in the system.
A current is produced in the coils' windings from the power amplifier which generates a magnetic
flux and an electromagnetic force proportional

Food and beverage control systems
Food and beverage control systems can help you introduce the same financial rigour to your dining
establishment or catering company that you'll find in manufacturing operations.
What is a food and beverage control system?
A food and beverage control system is a means of computerizing best practice within a restaurant or
catering operation. It gives managers a better idea of the flow of food through the restaurant,
enabling them to plan cash flow and stock control more effectively. At the sharp end, it provides
chefs with a more structured way of planning menus, taking into account nutritional and financial
considerations.

Creating a database of suppliers and ingredients will enable you to manage ingredient pricing more
effectively.
Nutrition
More applicable for specialist dining establishments (such as those in hospitals) or catering
companies, the ability to provide nutritional information on the food you serve can offer you a
competitive edge, and reassure customers particularly in areas such as school dinners, for example.
Recipe management
Many chefs either work from memory without any clear recipe, or have incomplete recipes that they
do not follow.
Codifying recipes helps you to manage your ingredients more effectively, while building in standard
estimates for wastage (such as the yield after peeling and chopping vegetables, or the wastage
caused by evaporation and transfer of a cream sauce from bowl to bowl). This will help you to price
your food more accurately. If you know exactly what a meal costs to make, you can price it more
accurately to undercut the competition while still making a quantifiable profit.
When looking at recipe management, consider the ability to nest recipes, because most recipes are
made up of multiple others. And a function to scale recipes easily for different quantities will be
invaluable for busy chefs.
Stock control and purchasing
Some food and beverage control systems give you the chance to inventory your food and create
purchase orders for more so you can maintain a minimum level of
