You have persuaded XelPharms CIO that wireless networking would be.pdf
You have persuaded XelPharm\'s CIO that wireless networking would benefit many of the
company\'s employees. However, he requests that you plan the
network carefully and begin with a pilot network before migrating hundreds of clients to use
wireless technology. You decide to begin with a pilot network
in the distribution facility. The distribution facility is 200 feet long by 120 feet wide. It houses
45 employees during each shift, all on the same floor. What is
your first step in planning the pilot network? As part of your later planning, draw the network,
including the quantity and optimal placement of access points. What pitfalls, some unique to this
environment, are you careful to avoid? What wireless standard do you recommend and why?
Solution
There are many factors that need to consider before developing wireless network like cost,
bandwidth, use and devices that need to deploy in network following are some points that need
to consider for planning network
There are a number of reasons for a company to implement wireless networking. Wi-fi makes it
much easier for workers to connect to the LAN from their laptops in conference rooms, break
rooms, and other areas that may not have wired Ethernet jacks (or may not have enough for the
number of people present).
A wireless network also provides a way for you to allow visitors to access the Internet with their
laptops or handhelds (for example, to check their e-mail).Rolling out a wireless LAN within your
organization, however, is more complicated than just plugging in a wireless access point (WAP).
You need to address a number of factors in the planning stage to ensure both accessibility and
security.
Steps to pilot network:-
1) Establish a pilot that will test and confirm how wireless can work within your business
campus and needs.
2) Tie in Internet access and a robust data security system.
3) Install wireless access points, and equip notebook PCs for wireless use (e.g., provide PC cards
or upgrade to PCs with integrated wireless connectivity built in).
4) Train and turn your participants loose with their wireless notebook PCs. 5 After the pilot,
build on what you learn to broaden your wireless LAN (WLAN) to cover other areas and users.
Here are some of the things you should consider as you prepare to go wireless :-
The first step in planning your wi-fi deployment is to determine who will be using your wireless
network. This can affect network design. If the wireless network is primarily to give visitors
Internet access, you will want to isolate it from your wired LAN, perhaps by placing it in a
DMZ. If the wireless LAN is for the use of your workers, you will need to give them access to
resources on the wired corporate network without compromising the security of the main LAN.
If both outsiders and employees need wireless, you may want to establish two separate WLANs
to meet the needs of each.
The next step is to look at what type of traffic will flow over the WLAN. This analysis is
necessa.

With the aid of an example, describe how RSVP works.
Solution
How RSVP Works
Basically,RSVP is based on signaling messages that traverse the network, allocating resources
along the way. RSVP is receiver-initiated, because sender initiation does not scale well to large,
multicast scenarios in which there are heterogeneous receivers. In multicast scenarios, the
application server sends out only one PATH message to multiple receiving computers, thus
conserving network bandwidth. In the case of multicast traffic flows, RESV messages from
multiple receivers are merged by taking the maximum values requested.
RSVP approaches to send data with best possible effort.
Following is the basic example how RSVP messages flow between a sender and receiver,
through the admission control host and intermediary hops.
Following steps involve in process of RSVP-
1. The multimedia server sends a PATH message requesting priority bandwidth to the
QoS ACS host . The message is ultimately headed to the receiver of the data. In the case of
multicast (multiple receivers), the PATH message is sent to the multicast address and received
by all hosts that are members of the multicast group. Note that it is RSVP messages that are
passed to the QoS ACS, not the data packets ultimately transmitted from sender to receiver.
Until confirmation of a reservation is received with a RESV message, data for the connection is
sent at a best-effort service level from the sending host. The best-effort service type instructs the
RSVP SP to use the application or service\'s QoS parameters as guidelines for service quality
requests, and makes reasonable effort to maintain the requested level of service. It does not make
any guarantees that requested QoS parameters are implemented or enforced.
2. If a QoS ACS server is present in the local subnet, the PATH message is routed via the
QoS ACS server. In this example, a QoS ACS host approves the request and forwards it to the
receiver (client). The PATH message travels through the network to the receiver, along the data
path determined by the network routing protocol.
3. A PATH state is maintained at each hop. Each PATH state contains a copy of the
PATH message and the IP address of the previous hop.
4. When a PATH message arrives at the intended receiver, the receiving host responds by
sending a RESV message that reserves the resources along the same network path traveled by the
PATH message.
Here, the receiver creates a RESV message, indicating that it wants to receive the data from the
multimedia server.

what causes hydrogen bonds to form between polar moleculesSolut.pdf
what causes hydrogen bonds to form between polar molecules?
Solution
Polar molecules are those, which dissociate in water and releases hydrogen (H+) or hydroxyl
ions (OH-). The partially charged opposite charges attract together, which results in hydrogen
bonding. For example, water molecules are held together by hydrogen bonding due to the
opposite partially polarity of hydrogen and hydroxyl ions..
What are the four main factors involved in the movement of ions acro.pdf
What are the four main factors involved in the movement of ions across the cell membrane in the
steady-state condition?
Solution
The four main factors are 1. Temperature ( increase in temperature makes membrane more
permeable) 2. pH ( membrane is more permeable in optimum pH) 3.membrane potential
(increase or decrease of the uptake of certain molecules or ions is dependent on membrane
potential. It increases with increasing potential) 4. Number of the channels present in the
membrane ( simply with the increase of number of channels more ions can pass through it).

Transitional epithelium is a stratified epithelium mainly existing in urothelium, urinary bladder,
prostrate and intercellular adhesion is essential for cell to cell communication & these are
existing where the epithelial tissues subjecting to traction & pressure. The prominent
intercellular adhesions existing in transitional epithelium are occluding junctions (zonula
occludens, zonula adherens (existing in prostrate), tight junctions, anchoring adhesive junctions
between cells (desmosomes), gap junctions (connexins) between the cells. Some of the junctions
are promoting intercellular adhesion in transitional epithelium..
The alpha-helix shown below is part of a water-soluble, globular prot.pdf
The alpha-helix shown below is part of a water-soluble, globular protein. Note that some amino
acids point \"toward\" you (Lys, Glu, Ser, Asp, etc.) and some point \"away\" from you (Phe, Ile,
Val, Ile, etc.). Which side of the helix (the side with the amino acids pointing \"toward\" you or
the side with the amino acids pointing \"away\" from you) would likely be the side of the helix
that is in contact with the cytoplasm (the watery fluid inside all cells), as opposed facing inward
toward the \"core\" of the protein?
Solution
Lys, Ser, Glu and Asp are hydrophilic amino acids whereas Phe, Ile, Val, Ile are hydrophobic
amino acids.
Hydrophilic amino acids seek contact with water whereas hydrophobic amino acids do not.
The hydrophilic amino acids tend to be on the outside of the protein molecules. Therefore the
hydrophilic amino acids would be in contact with the cytoplasm. The hydrophobic amino acids
would tend to orient towards the interior of the folded protein molecule..

in java Can we create an object of type Interface Explain your answ.pdf
in java Can we create an object of type Interface? Explain your answer.
Solution
No, we cannot create an instance of interface in java because interface contains only abstract
methods (ie. methods which are only declared) and as abstract methods do not have a body (of
implementation code), we cannot create an object of interface.
Though we can create instance of the class implementing the interface.
But we can refer to object that implements an interface.
example,
public interface Pet
{
}
public class Dog implements A
{
}
public static void main(String[] args)
{
Pet ob = new Dog();
//Pet test = new Pet(); // compilation error
}
Also,
Anonymous classes can implement interfaces, and it is the only time a class implementing an
interface without the
\"implements\" keyword.
It is possible to create Interface object with anonymous inner classes as shown below :
interface Sample {
public void display();
}
class Demo {
Sample p = new Sample() {
public void display() {
System.out.println(\"Interfce example.\");
}
};
}.

Solution
1) the answer is RNA - SsRNA.. It is a protein which is involved in the termination of
transcription.!! It acts on the SsRNA after the open reading frame where there is G/C less
sequence..!!
2) the answer is 4.. As 4^ 3 = 64 codes for 20 amino acids so we can say that there is
degeneracy.. If there is 64 codons it will code for only 64 amino acids for outer organism. But
there are 128 amino acids given Similarly, 4^4= 256 which can code for 128 a.a including
degeneracy as it is closest of no of amino acids.

Explain the sources of police subculture. king undercover would affec.pdf
Explain the sources of police subculture. king undercover would affect an officer in terms of
various components of police subeulture.
Solution
Answer- Part1
Police Subculture-
It\'s the culture of Police Officers.
Cops gathering at doughnut shops and eating doughnuts is part of police subculture which
became popular.
Cops are tied to the colour blue. They use police code even while not in the work-place. They
call each other by their last names only outside of work as is standard practice while on the job.
Part of cop subculture is to moonlight as bouncers, private eyes and other gigs when they can not
get any overtime. Part of the culture is that cops live off their OT. If you look up how much cops
get paid you\'ll find that OT is usually 20-50% of their wages. The culture has their slang. New
Recruits are called Rooks/Boots.
So, Police subculture is defined as a specific set of beliefs, attitudes, and behaviours exhibited by
those in law enforcement. Because police officers spend the majority of their time dealing with
crime, they tend to view members of the public as untrustworthy and potentially hostile.
Sources of Police Subculture
1- Organization Factors Cont.
2- Night Shifts:
3- Street Environment
4- Culture-shaping implications between the police and citizens
5- Behavior can be influenced due to personal beliefs and circumstances that are encountered
6- Young officers get frustrated due to being disillusioned by the routine
7- Most common violent encounters that officers respond to are between friends and
acquaintances, domestic situations also
8- Traffic stop interactions negatively affect police subculture, an encounter between officer and
driver are doomed
9- Other Criminal Justice Agencies
10- Administration Cont.
Answer- Part 2
Undercover officers are mainly hard-working minority men and women who grew up in some of
the toughest neighbourhoods in the city who chose to come into the police and try to make a
difference. And the police uses them.
Working as an undercover would affect an officer in terms of various components of police
subculture. Some Possible components could be as follows-:
1- Undercover agents are frequently required to be in hostile environments in which they give up
control and do not have dominion.
2- The level of danger and unpredictability is markedly increased.
3- Their sense of moral superiority may be increased, as they spend more time surrounded by
criminals. 4- Their sense of us versus them will have to be concealed to avoid giving themselves
away. Their need for secrecy may extend to everyone they know to protect their cover, thus
increasing their isolation.
5- Their bravery and ability to deceive are likely to be continually challenged..

Cuckoos are birds that practice brood parasitism. Instead of raising.pdf
Cuckoos are birds that practice brood parasitism. Instead of raising her own young, a mother
cuckoo finds another bird’s nest and lays her egg when the other is away. The other bird dutifully
cares for the cuckoo egg until it hatches. The cuckoo hatchling, before it can even see, senses the
touch of other eggs in the nest and ejects them by pushing against them with its body.
Characterize the hatchling’s behavior, using Tinbergen’s first two questions for understanding a
behavior. What is the stimulus for the behavior? What is the response? How does prior
experience influence the behavior?
Solution
The cuckoo is the best known brood parasite an expert in the art of cruel deception. Its strategy
involves stealth, surprise and speed. Cuckoos will not build their own nest. Female cuckoos will
find another bird’s nest and in the absence of the parent she removes one of the original egg and
removing it from nest laying her own egg.
Cuckoos parasitize the nests of a large variety of bird species and carefully mimic the colour and
pattern of their own eggs to match that of their hosts. To give proper parental care to their egg.
The bright red mouth act as stimulus to the foster parent to feed it regularly. It carefully mimic
the colour and pattern of their own egg to match with the hosts..

CASE STUDY TEXT:
The executives who lead Voici Brands\' various businesses own their bottom lines. Now the
CEO wants to centralize supply chain operations. The businesses may save money -- but the
executives will lose control. How should this battle be fought?
HBR\'s cases, which are fictional, present common managerial dilemmas and offer concrete
solutions from experts.
WHEN JACK EMMONS, CEO of Voici Brands, stepped into the vast, brightly lit production
area of the \"supply chain city\" in Shanghai, his jaw dropped. An ocean of uniformly kerchiefed
and aproned Chinese women bowed over their sewing. There must have been a thousand of
them.
\"Each workstation is limited to a six-inch stack of material,\" Xao Li, the sales representative,
pointed out in skillful English. \"This floor is divided into three sections, one for each client. As
you can see, our employees work under the best conditions. NGOs have nothing to complain
about.\"
Li led Jack and Robert Dodds, Voici\'s CFO and Jack\'s sidekick on this trip, along a glistening
green aisle, past row upon row of busy workers. Jack watched, fascinated, as the workers deftly
pulled thread and material through the machines. In the distance, Robert caught sight of a
Caucasian woman wandering the aisles in one section of the production floor.
\"Who is that over there?\" Robert asked.
\"Ah,\" said Li, peering knowingly over his designer glasses at Robert, then at Jack. \"I believe
she is an inspector for Marquise. Her presence here ensures the high and consistent quality that
Marquise expects.\"
The reference to Voici Brands\' major competitor was hardly lost on Jack. Two years earlier,
Marquise had consolidated its supply chain operations by outsourcing all its product lines to the
supply chain city. In doing so, Marquise had shrunk the time from fashion design to products\'
arrival in its retail stores from 50 weeks to 60 days, boosting its bottom line by 20%. Only a
small part of the increase in profits was due to lower Chinese labor costs. Most of it was due to
the faster time to market, which allowed Marquise to respond more quickly to the whims of its
fashion-conscious customers.
As Jack and Robert followed their host out of the cavernous facility, Jack realized that the
sewing operation was only the tip of the iceberg. Adjacent buildings housed every other stage of
apparel production, such as weaving and fabric dyeing. In one dazzling, Silicon Valley-style
office building, Chinese and Western engineers and designers worked side by side at large LCD
screens.
\"Our professionals can help you with every stage of production, in all your lines,\" said Li. \"We
take care of everything right here, from design through delivery. Thi.
Consider three hypothetical countries, Kipr, Ispania, and Atlantida, .pdf
Consider three hypothetical countries, Kipr, Ispania, and Atlantida, that seek membership in the
European Monetary Union (EMU). Suppose that the average inflation rate of the three European
countries with the lowest inflation rates is 2.0%, and the average Interest rate of those countries
is 2.2%. Evaluate the characteristics of Kpr, Ispania, and Atlantida presented In the following
table using the Maastricht convergence criteria. Then, use the dropdown menus in the bottom
row to identify whether each country is eligible to become an EMU member.
Solution
The nominal convergence criteria which must be met by the countries joining the Economic and
Monetary Union were laid down in the European Union Treaty which is also known as the
Maastricht Treaty. They include:
The first three convergence criteria are designed to ensure monetary stability by supporting a
fixed exchange rate regime among member countries. The stability of the euro is reinforced by
the last two criteria, which protect the European Union from threats of inflation which may arise
from government budget deficits.
The Country KIPR cannot became a member of European Monitary Union (EMU) because this
country is not fulfilling either of the critieria needed except the last criterion.
The Country ISPANIA also cannot became a member of EMU because this country is not
meeting the third criterion which requires not to devalue their exchange rate in the period of
atleast two years.
The Country ATLANTIA can became of member of EMU because this country is fulfilling all
the requirements needed..

Answer the following questions with detailed justifications a) What i.pdf
Answer the following questions with detailed justifications a) What is the bandwidth of the
human voice? b) What is the bandwidth of our hearing process? c) What is the bandwidth used in
mobile speech communications ?
Solution
a)
A voice frequency (VF) or voice band is one of the frequencies, within part of the audio range,
that is used for the transmission of speech.
In telephony, the usable voice frequency band ranges from approximately 300 Hz to 3400 Hz. It
is for this reason that the ultra low frequency band of the electromagnetic spectrum between 300
and 3000 Hz is also referred to as voice frequency, being the electromagnetic energy that
represents acoustic energy at baseband. The bandwidth allocated for a single voice-frequency
transmission channel is usually 4 kHz, including guard bands, allowing a sampling rate of 8 kHz
to be used as the basis of the pulse code modulation system used for the digital PSTN. Per the
Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the
highest component of the voice frequency via appropriate filtering prior to sampling at discrete
times (4 kHz) for effective reconstruction of the voice signal.
b)
Hearing range describes the range of frequencies that can be heard by humans or other animals,
though it can also refer to the range of levels. The human range is commonly given as 20 to
20,000 Hz, though there is considerable variation between individuals, especially at high
frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal.
Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine
investigation for hearing loss usually involves an audiogram which shows threshold levels
relative to a normal.
Several animal species are able to hear frequencies well beyond the human hearing range. Some
dolphins and bats, for example, can hear frequencies up to 100 kHz. Elephants can hear sounds
at 14–16 Hz, while some whales can hear subsonic sounds as low as 7 Hz (in water).
c)
The present day telephone infrastructure limits the bandwidth of telephonespeech to 300–3400
Hz, whereby conversational speech falls mostly within 50–8000 Hz..

(3) How would you compare the perils of maritime shipping to that of airfreight?
(4) What is Lloyds of London and under what conditions might you use their services?
Solution
(1) In the event a company, entity or person on one of the following lists appears to match a
potential party in an export transaction, additional due diligence is required before proceeding.
Depending on which list the match was found, a match indicates either: there is a strict export
prohibition; a specific license requirement; or the presence of a \"red flag\".
Prior to taking any further actions, users are to consult the requirements of the specific list on
which the company, entity or person is identified by reviewing the webpage of the agency
responsible for the list.
Denied Persons List
A list of individuals and entities that have been denied export privileges. Any dealings with a
party on this list that would violate the terms of its denial order are prohibited.
Entity List
The Entity List identifies foreign parties that are prohibited from receiving some or all items
subject to the EAR unless the exporter secures a license. Those persons present a greater risk of
diversion to weapons of mass destruction (WMD) programs, terrorism, or other activities
contrary to U.S. national security or foreign policy interests. By publicly listing such persons, the
Entity List is an important tool to prevent unauthorized trade in items subject to the EAR.
BIS can add to the Entity List a foreign party, such as an individual, business, research
institution, or government organization, for engaging in activities contrary to U.S. national
security and/or foreign policy interests. In most instances, license exceptions are unavailable for
the export, reexport, or transfer (in-country) to a party on the Entity List of items subject to the
EAR. Rather, a prior license is required, usually subject to a policy of denial. For guidance
concerning the prohibitions and license application review policy applicable to a particular party,
please review that party\'s entry on the list. Procedures for removal from the Entity List appear in
section 744.16 of the EAR.
Unverified List
A list of parties whose bona fides BIS has been unable to verify. No license exceptions may be
used for exports, reexports, or transfers (in-country) to UVL parties. A statement must be
obtained from such parties prior to shipping items not subject to a license requirement. See
Section 744.15 of the EAR.

in java Can we create an object of type Interface Explain your answ.pdf
in java Can we create an object of type Interface? Explain your answer.
Solution
No, we cannot create an instance of interface in java because interface contains only abstract
methods (ie. methods which are only declared) and as abstract methods do not have a body (of
implementation code), we cannot create an object of interface.
Though we can create instance of the class implementing the interface.
But we can refer to object that implements an interface.
example,
public interface Pet
{
}
public class Dog implements A
{
}
public static void main(String[] args)
{
Pet ob = new Dog();
//Pet test = new Pet(); // compilation error
}
Also,
Anonymous classes can implement interfaces, and it is the only time a class implementing an
interface without the
\"implements\" keyword.
It is possible to create Interface object with anonymous inner classes as shown below :
interface Sample {
public void display();
}
class Demo {
Sample p = new Sample() {
public void display() {
System.out.println(\"Interfce example.\");
}
};
}.

I need help in matlab.The task is echo removing from the signal.Suppose we have a musical
signal include echoes, so we have to design the filter to remove echo.
In attach pics, there is complete description about the question. where h[O] is the signal
attenuation of the direct path between the source of music and the microphone, and h[k]for k >0
can be viewed as the coefficients of the echoes. Choose the coefficients of the echoes as follows:
h[0] = 1, h[50001 0.5 h[90001 0.02 STEP 1 Compute, plot, and play the following music signal
yfn: y[n] = h[k]x(n-k] k=0 where xfk] is your own original musical signal from project
deliverable 2. When you listen to the y[n], you should feel the echoes in the signal. STEP 2: In
the second step, we pretend like we do not know the original signal, and all we have is the
musical signal with echoes, which is yln]. Now, your task is to design a filter, whose impulse
response is denoted as gln), in order to remove the echoes. So, the overall system (including
STEP 1 and STEP 2) looks like

1) the answer is RNA - SsRNA.. It is a protein which is involved in the termination of
transcription.!! It acts on the SsRNA after the open reading frame where there is G/C less
sequence..!!
2) the answer is 4.. As 4^ 3 = 64 codes for 20 amino acids so we can say that there is
degeneracy.. If there is 64 codons it will code for only 64 amino acids for outer organism. But
there are 128 amino acids given Similarly, 4^4= 256 which can code for 128 a.a including
degeneracy as it is closest of no of amino acids.

Explain the sources of police subculture. king undercover would affec.pdf
Explain the sources of police subculture. king undercover would affect an officer in terms of
various components of police subeulture.
Solution
Answer- Part1
Police Subculture-
It\'s the culture of Police Officers.
Cops gathering at doughnut shops and eating doughnuts is part of police subculture which
became popular.
Cops are tied to the colour blue. They use police code even while not in the work-place. They
call each other by their last names only outside of work as is standard practice while on the job.
Part of cop subculture is to moonlight as bouncers, private eyes and other gigs when they can not
get any overtime. Part of the culture is that cops live off their OT. If you look up how much cops
get paid you\'ll find that OT is usually 20-50% of their wages. The culture has their slang. New
Recruits are called Rooks/Boots.
So, Police subculture is defined as a specific set of beliefs, attitudes, and behaviours exhibited by
those in law enforcement. Because police officers spend the majority of their time dealing with
crime, they tend to view members of the public as untrustworthy and potentially hostile.
Sources of Police Subculture
1- Organization Factors Cont.
2- Night Shifts:
3- Street Environment
4- Culture-shaping implications between the police and citizens
5- Behavior can be influenced due to personal beliefs and circumstances that are encountered
6- Young officers get frustrated due to being disillusioned by the routine
7- Most common violent encounters that officers respond to are between friends and
acquaintances, domestic situations also
8- Traffic stop interactions negatively affect police subculture, an encounter between officer and
driver are doomed
9- Other Criminal Justice Agencies
10- Administration Cont.
Answer- Part 2
Undercover officers are mainly hard-working minority men and women who grew up in some of
the toughest neighbourhoods in the city who chose to come into the police and try to make a
difference. And the police uses them.
Working as an undercover would affect an officer in terms of various components of police
subculture. Some Possible components could be as follows-:
1- Undercover agents are frequently required to be in hostile environments in which they give up
control and do not have dominion.
2- The level of danger and unpredictability is markedly increased.
3- Their sense of moral superiority may be increased, as they spend more time surrounded by
criminals. 4- Their sense of us versus them will have to be concealed to avoid giving themselves
away. Their need for secrecy may extend to everyone they know to protect their cover, thus
increasing their isolation.
5- Their bravery and ability to deceive are likely to be continually challenged..

Cuckoos are birds that practice brood parasitism. Instead of raising.pdf
Cuckoos are birds that practice brood parasitism. Instead of raising her own young, a mother
cuckoo finds another bird’s nest and lays her egg when the other is away. The other bird dutifully
cares for the cuckoo egg until it hatches. The cuckoo hatchling, before it can even see, senses the
touch of other eggs in the nest and ejects them by pushing against them with its body.
Characterize the hatchling’s behavior, using Tinbergen’s first two questions for understanding a
behavior. What is the stimulus for the behavior? What is the response? How does prior
experience influence the behavior?
Solution
The cuckoo is the best known brood parasite an expert in the art of cruel deception. Its strategy
involves stealth, surprise and speed. Cuckoos will not build their own nest. Female cuckoos will
find another bird’s nest and in the absence of the parent she removes one of the original egg and
removing it from nest laying her own egg.
Cuckoos parasitize the nests of a large variety of bird species and carefully mimic the colour and
pattern of their own eggs to match that of their hosts. To give proper parental care to their egg.
The bright red mouth act as stimulus to the foster parent to feed it regularly. It carefully mimic
the colour and pattern of their own egg to match with the hosts..

CASE STUDY TEXT:
The executives who lead Voici Brands\' various businesses own their bottom lines. Now the
CEO wants to centralize supply chain operations. The businesses may save money -- but the
executives will lose control. How should this battle be fought?
HBR\'s cases, which are fictional, present common managerial dilemmas and offer concrete
solutions from experts.
WHEN JACK EMMONS, CEO of Voici Brands, stepped into the vast, brightly lit production
area of the \"supply chain city\" in Shanghai, his jaw dropped. An ocean of uniformly kerchiefed
and aproned Chinese women bowed over their sewing. There must have been a thousand of
them.
\"Each workstation is limited to a six-inch stack of material,\" Xao Li, the sales representative,
pointed out in skillful English. \"This floor is divided into three sections, one for each client. As
you can see, our employees work under the best conditions. NGOs have nothing to complain
about.\"
Li led Jack and Robert Dodds, Voici\'s CFO and Jack\'s sidekick on this trip, along a glistening
green aisle, past row upon row of busy workers. Jack watched, fascinated, as the workers deftly
pulled thread and material through the machines. In the distance, Robert caught sight of a
Caucasian woman wandering the aisles in one section of the production floor.
\"Who is that over there?\" Robert asked.
\"Ah,\" said Li, peering knowingly over his designer glasses at Robert, then at Jack. \"I believe
she is an inspector for Marquise. Her presence here ensures the high and consistent quality that
Marquise expects.\"
The reference to Voici Brands\' major competitor was hardly lost on Jack. Two years earlier,
Marquise had consolidated its supply chain operations by outsourcing all its product lines to the
supply chain city. In doing so, Marquise had shrunk the time from fashion design to products\'
arrival in its retail stores from 50 weeks to 60 days, boosting its bottom line by 20%. Only a
small part of the increase in profits was due to lower Chinese labor costs. Most of it was due to
the faster time to market, which allowed Marquise to respond more quickly to the whims of its
fashion-conscious customers.
As Jack and Robert followed their host out of the cavernous facility, Jack realized that the
sewing operation was only the tip of the iceberg. Adjacent buildings housed every other stage of
apparel production, such as weaving and fabric dyeing. In one dazzling, Silicon Valley-style
office building, Chinese and Western engineers and designers worked side by side at large LCD
screens.
\"Our professionals can help you with every stage of production, in all your lines,\" said Li. \"We
take care of everything right here, from design through delivery. Thi.
Consider three hypothetical countries, Kipr, Ispania, and Atlantida, .pdf
Consider three hypothetical countries, Kipr, Ispania, and Atlantida, that seek membership in the
European Monetary Union (EMU). Suppose that the average inflation rate of the three European
countries with the lowest inflation rates is 2.0%, and the average Interest rate of those countries
is 2.2%. Evaluate the characteristics of Kpr, Ispania, and Atlantida presented In the following
table using the Maastricht convergence criteria. Then, use the dropdown menus in the bottom
row to identify whether each country is eligible to become an EMU member.
Solution
The nominal convergence criteria which must be met by the countries joining the Economic and
Monetary Union were laid down in the European Union Treaty which is also known as the
Maastricht Treaty. They include:
The first three convergence criteria are designed to ensure monetary stability by supporting a
fixed exchange rate regime among member countries. The stability of the euro is reinforced by
the last two criteria, which protect the European Union from threats of inflation which may arise
from government budget deficits.
The Country KIPR cannot became a member of European Monitary Union (EMU) because this
country is not fulfilling either of the critieria needed except the last criterion.
The Country ISPANIA also cannot became a member of EMU because this country is not
meeting the third criterion which requires not to devalue their exchange rate in the period of
atleast two years.
The Country ATLANTIA can became of member of EMU because this country is fulfilling all
the requirements needed..

Answer the following questions with detailed justifications a) What i.pdf
Answer the following questions with detailed justifications a) What is the bandwidth of the
human voice? b) What is the bandwidth of our hearing process? c) What is the bandwidth used in
mobile speech communications ?
Solution
a)
A voice frequency (VF) or voice band is one of the frequencies, within part of the audio range,
that is used for the transmission of speech.
In telephony, the usable voice frequency band ranges from approximately 300 Hz to 3400 Hz. It
is for this reason that the ultra low frequency band of the electromagnetic spectrum between 300
and 3000 Hz is also referred to as voice frequency, being the electromagnetic energy that
represents acoustic energy at baseband. The bandwidth allocated for a single voice-frequency
transmission channel is usually 4 kHz, including guard bands, allowing a sampling rate of 8 kHz
to be used as the basis of the pulse code modulation system used for the digital PSTN. Per the
Nyquist–Shannon sampling theorem, the sampling frequency (8 kHz) must be at least twice the
highest component of the voice frequency via appropriate filtering prior to sampling at discrete
times (4 kHz) for effective reconstruction of the voice signal.
b)
Hearing range describes the range of frequencies that can be heard by humans or other animals,
though it can also refer to the range of levels. The human range is commonly given as 20 to
20,000 Hz, though there is considerable variation between individuals, especially at high
frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal.
Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine
investigation for hearing loss usually involves an audiogram which shows threshold levels
relative to a normal.
Several animal species are able to hear frequencies well beyond the human hearing range. Some
dolphins and bats, for example, can hear frequencies up to 100 kHz. Elephants can hear sounds
at 14–16 Hz, while some whales can hear subsonic sounds as low as 7 Hz (in water).
c)
The present day telephone infrastructure limits the bandwidth of telephonespeech to 300–3400
Hz, whereby conversational speech falls mostly within 50–8000 Hz..

(3) How would you compare the perils of maritime shipping to that of airfreight?
(4) What is Lloyds of London and under what conditions might you use their services?
Solution
(1) In the event a company, entity or person on one of the following lists appears to match a
potential party in an export transaction, additional due diligence is required before proceeding.
Depending on which list the match was found, a match indicates either: there is a strict export
prohibition; a specific license requirement; or the presence of a \"red flag\".
Prior to taking any further actions, users are to consult the requirements of the specific list on
which the company, entity or person is identified by reviewing the webpage of the agency
responsible for the list.
Denied Persons List
A list of individuals and entities that have been denied export privileges. Any dealings with a
party on this list that would violate the terms of its denial order are prohibited.
Entity List
The Entity List identifies foreign parties that are prohibited from receiving some or all items
subject to the EAR unless the exporter secures a license. Those persons present a greater risk of
diversion to weapons of mass destruction (WMD) programs, terrorism, or other activities
contrary to U.S. national security or foreign policy interests. By publicly listing such persons, the
Entity List is an important tool to prevent unauthorized trade in items subject to the EAR.
BIS can add to the Entity List a foreign party, such as an individual, business, research
institution, or government organization, for engaging in activities contrary to U.S. national
security and/or foreign policy interests. In most instances, license exceptions are unavailable for
the export, reexport, or transfer (in-country) to a party on the Entity List of items subject to the
EAR. Rather, a prior license is required, usually subject to a policy of denial. For guidance
concerning the prohibitions and license application review policy applicable to a particular party,
please review that party\'s entry on the list. Procedures for removal from the Entity List appear in
section 744.16 of the EAR.
Unverified List
A list of parties whose bona fides BIS has been unable to verify. No license exceptions may be
used for exports, reexports, or transfers (in-country) to UVL parties. A statement must be
obtained from such parties prior to shipping items not subject to a license requirement. See
Section 744.15 of the EAR.
