Deregulation of the U.S. Airline Industry Essay example
Deregulation of the U.S. airline industry has resulted in ticket prices dropping by a third, on an inflation–adjusted basis. As a result some 1.6 million
people fly on 4,000 aircraft every day. Airlines carried 643 million passengers in 1998, a 25% increase over 1993 and the FAA estimates that the
nationВЎВ¦s airline system will have to accommodate 917 million passengers by the year 2008. The growth in air travel threatens to overwhelm the
presently inadequate air traffic control system, which has not kept pace with available technology in navigation, communications, and flight
surveillance. Much of the equipment used for air traffic control today is based on fifty–year–old technology; for example, analog simplex voice links for

On March 11, 1999, the FAA released the NAS Architecture Version 4.0 to the public. Key influences on the architecture include the 1996 White House
Commission on Aviation Safety and Security, which recommended that the FAA accelerate modernization of the NAS, and the 1997 National Civil
Aviation Review Commission, which recommended funding and performance management methods for implementing NAS modernization. It
describes the agencyВЎВ¦s modernization strategy from 1998 through 2015. Based on the Free Flight operational concept, Version 4.0 contains
capabilities, technologies, and systems to enhance the safety of the aviation system and provide users and service providers with more efficient
services. Free Flight centers on allowing pilots, whenever practical, to choose the optimum flight profile. This concept of operations is expected to
decrease user costs, improve airspace flexibility, and remove flight restrictions.
The NAS Architecture is divided into three modernization phases and its implementation is being synchronized with the International Civil Aviation
Organization to ensure interoperability and global integration.

Recommendations For Prevention And Mitigation
Recommendations for Prevention/Mitigation
Many ports do not have cyber response plans contained within broader risk plans (Kramek). All of the ports studied by Kramek had a dedicated
security officer and a dedicated IT staff, but the security officers' focus usually remained on traditional physical security threats, and IT was a separate
and distinct department from security (Kramek). Kramek states, "cyber security threats were not part of the security officer's response portfolio". Most
security officers thought that their IT staff would notify them in some form or fashion if a cyber incident threatened port operations (Kramek).
However, when during the response this notification to the security officers would be made is unclear given the lack of written response plans
(Kramek). Ports need their IT department to be continually communicating with their security department. This would keep all the staff in the loop on
current difficulties and security impairments and allow staff to find a cyber incident before it becomes too bad. Ports need to make sure that they have
thorough written response plans in the case of a cyber security incident and that all IT and security staff that will be involved are ready to execute the
plan if needed. These plans need to take into account that many industrial control systems are dependent, like many systems at ports and marine
terminals, and run off computer networks (Sain). As stated by Bethann Rooney, manager of security for the Port

Evaluating The Nist 800-39 : Managing Information Security...
Next, C3J will use the NIST 800–39: Managing Information Security Risk to generate a response for each risk.
Note that three of the identified risks are global, three relate to physical assets, one is an intangible asset...According to the NIST SP 800–39, AAE
could use five strategies to respond to risks. It could chose to: 1) accept risks, 2) avoid risks, 3) transfer/share the risks, 4) mitigate risks, or 5)
avoidance risks. Following are the recommended risk responses along with the recommended strategies generated by AAE for the assessment:
Risk 1 – Cyber Attack (Global):
C3J recommends AAE to use the defense in–depth approach to reduce the damage caused by a data breach. Defense in–depth means that AAE will use
multiple systems to protect company data. The concept works on the premise that if one system fails, another will be in place to protect the data. These
include Develop safeguards to protect data (encryption)...Implement solutions to detect a breach...Implement solutions to backup and recover lost or
compromised data...In addition, AAE will implement a security awareness program...If a breach occurs the IT Director will notify the Executive
Director and any affected parties before activating the AAE incident response plan (IRP).
Risk 2 – Rising aeronautical fuel prices (Global):
The airport Executive Director will work with the commercial airlines at AAE to invest in oil futures for five years into the future. This entails doing

Synchronous is an adjective that describes an event that is coordinated in time. Synchronous communications works in a way that both hosts will be
communicating consistently to continue that communication. By this I mean, that there should be continuous stream of data flow between both hosts
to keep that communication going. An example of this is a phone call, when one host (person) communicates with another host, both hosts will have an
active connection between them during Synchronous communication. The first host can send a packet of data (talk) while the second host will receive
that data (Listen) simultaneously and then the first host will receive the data while the second host is sending the data simultaneously. This
communication is used commonly used in telecommunications such as; phone calls, Skype calls etc. Synchronous communication is used in these
cases instead of Asynchronous because these things require both hosts be active at the same time. Synchronous communication is also used for things
such as streaming on Netflix which requires both the server and client accessing Netflix to be active. Peer to peer transfer (sending a file directly to a
friend over the internet) also requires that both hosts be active, if only one host was active then the file wouldn't be able to be

Mangroves: A Vital Part of the Environment
A mangrove can be defined as a tree, shrub, palm or ground fern, usually exceeding a length of one meter in height. It will generally grow above the
average tidal level in a marine coastal environment. The word mangrove can also mean the same as 'rainforest' or 'tidal forest' because this is the
environment, when in large quantities, mangroves are known to create. According to MARINEBIO, (1998–2014) most mangrove species can be found
in South East Asia, The United States and the western Hemisphere; there are approximately 70 different species of mangroves, ranging from small
shrubs to 40m tall trees. Mangroves are a vital part of the environment, but are quickly being damaged and lost under construction and pollution. If this
continues, they will become extinct.
In their environment, Mangroves are prone to living in areas along the coastline, in warm, salty waters. Because Mangroves grow in this habitat, they
must adapt to their surroundings by working together with their roots, cells and leaves to remove all of the unnecessary salt and excess water. (Duke,
2007) The most common areas near the coastline where mangroves can be found is where the compostition of the soil is rocky and wet clay/silt.
Mangroves in themselves are a home to thousands of different organisms who strive off of their shelter and protection. Examples of this can include
birds nesting in the outer water roots, and sessile organisms clinging to the underwater roots.
Mangroves are essential for areas such

Mobile Network : A Main Way Of Communication
Table of Contents
I. Introduction
Mobile networks are considered as a main way of communication between the people in the entire world. The core network ensures that mobile users
can exchange information, share data and communicate more effectively with those using other access networks or external networks.
II. Concept
A mobile phone network is made up of a large number of signal areas called cells which join or overlap each other to form a large coverage area.
Users on the network can cross into different cells without losing connection.
First within each cell, a mobile phone tower or base station will be found to send and receive the mobile transmissions. A mobile device will connect
to the nearest or least congested base station ... Show more content on Helpwriting.net ...
A typical cellular network can be envisioned as a mesh of hexagonal cells, each with its own base station at the center. The cells slightly overlap at the
edges to ensure that users always will remain within range of a base station.
At the center of each group of cells, the base station functions as the hub for those cells – not of the entire network, but of that individual piece of the
network. RF signals are transmitted by an individual phone and received by the base station, where they are then re–transmitted from the base station
to another mobile phone. The transmitting and receiving processes are done over two slightly different frequencies.
Central switching centers are used to connect base stations one to another. They track calls and transfer them from one base station to another as callers
move between cells; the handoff is unnoticeable and (ideally) seamless. Base stations are also connected to the main telephone network, and thus can
relay mobile calls to landline phones.

Before the age of digital mobile networks, all cell phones broadcast analog signals. This intended using the Advanced Mobile Phone System (AMPS)
standard, which runs in a range of frequencies between 824MHz and 894MHz, dubbed the 800MHz band.
This type of analog transmission was the first generation of cellular phone technology, or what some refer to as 1G. Because analog phones could

c. Local Exchanges – serves a group of ... Show more content on Helpwriting.net ...
Services are brought to the consumer or business through a cabling link between the consumer or business and the local exchange. This network of
cabling is also referred to as the distribution network, since the signals that are sent or received by the local exchange need to be distributed to a large
number of connection points and types of consumers. The local exchange acts as the convergence point, or warehouse of sorts, for the information sent
from consumers and the point at which services from the global telecommunications are distributed to the consumers. iv. Regional/Metro Networks –
referred to as MAN (metro area network), cover the city and are responsible for aggregating info from the local exchanges of a specific service
provider, as well as independent providers, and sending the info to the regional and long haul/core networks. A regional network or Wide area
network (WAN) is a larger version of a MAN and is responsible for aggregating the info from metro networks. The regional network is usually the
last point before the info traffic is put onto the core network. A key requirement of a WAN owner is that it leases lines to other telecommunications
service providers because WANs have to aggregate large portions of data from multiple network operators.

From the 13.000 ports installed in the digital switches, only 6.200 have been sold until end of 2005. Six years after the implementation of the service
in the network, and being in the company 's product portfolio, the number of customers using ISDN service is less than 1.2% from the total number of
customers. Although the company introduced the service almost at the same time as other telecom operators in Europe, the number of users in others
countries is significantly higher (28% in Slovenia, 10% in Hungary, 32% in Germany). The disproportion is evident. The sales of ISDN in the

Company are a problem.
Ron (2000) stated: "Since ISDN is digital service and capable of high rates of speed over the same pair of copper wires that service the POTS
infrastructure, combining voice and data over a common medium, results in improved service capacity and higher quality"(p.70).
Although ISDN is a digital service and should result in higher quality, the perception of MakTel customers of ISDN as a poor service quality is one of
the biggest problems for increasing the sales.
According to the faults statistics for 2005, on existing 6200 ISDN subscribers were reported more than 2400 faults. In the previous years, the ratio
between the number of subscribers and the faults reported was

Steps in Auditing Networks
The very first step in auditing networks is to define where to analyze the traffic. Taking a common scenario for analysis, the following assumptions
were made. There is a switched network made up of a number of switches, several terminals and a file server. Network performance has dropped,
however the cause is unknown. There is no IDS (Intrusion Detection System) that can alarm or inform about attacks or network malfunction. Also,
it is known that there are no problems with the transfer rate of the file server to LAN (Local Area Network) terminals [3]. Furthermore, network
equipment does not have Netflow protocols to analyze traffic remotely. Wireshark was chosen to analyze the above scenario. The first doubt which
arises is where to install Wireshark. It would seem logical to install Wireshark on the file server itself to analyze the traffic that flows through this
network segment. However, there could be situations in which there is no access to the server physically or quite simply for security reasons. Thus,
Wireshark cannot be installed there. Some alternatives are provided in the following paragraphs that enable to capture traffic without having to install
Wireshark on the server. A. Using a Hub If a user connects a node where Wireshark is installed to one of the switch ports, he will only see the packets
that occur between the switch and his terminal, however this is not desired for traffic analysis. The switch divides the network into segments creating
separate

Advantages And Disadvantages Of Antennas
Antennas – antennas serve as interfaces between transmitted/received signals and transmitters/receivers. Depending on the type, shape, and size of the
transmitter antenna, the transmitted signal will have directionality and polarization properties. A receiver antenna is designed to match this
directionality and polarization so that the transmitted signal can be received. Earth–facing antennas are usually designed to provide a coverage region
with a particular contour shape. Typically, horn antennas and parabolic reflector antennas are used for this purpose. In some satellites, multiple transmit
antennas (lens antennas and antenna arrays) are used to generate multiple "spot beams" for higher signal directionality and gain. The coverage region
and the spot beams may be fixed or dynamically formed depending on the application. Some advanced experimental... Show more content on

Most of today's satellites are GEO.In a relatively short span of time, satellite technology has developed from the experimental (Sputnik in 1957) to the
sophisticated and powerful. Future communication satellites will have more onboard processing capabilities, more power, and larger–aperture
antennas that will enable satellites to handle more bandwidth. Further improvements in satellites' propulsion and power systems will increase their
service life to 20–30 years from the current 10–15 years. In addition, other technical innovations such as low–cost reusable launch vehicles are in
development. With increasing video, voice, and data traffic requiring larger amounts of bandwidth, there is no shortage of emerging applications that
will drive demand for the satellite services in the years to come. The demand for more bandwidth, coupled with the continuing innovation and
development of satellite technology, will ensure the long–term viability of the commercial satellite industry well into the 21st

Sioux Falls, SD is one of McBride's locations. McBride Financial Services utilizes sensitive equipment and toxic chemicals during its manufacturing
process. These high end and dangerous items place the location at risk. Some of the threats include: use of toxic chemicals, public transportation, crime,
and acts of terrorism. It is McBride's responsibility to mitigate these threats.
Use of Toxic Chemicals
McBride Financial Services must control the risk of its use of toxic chemicals. "In its 2009 report Science and Decisions: Advancing Risk Assessment,
the NAS recommended a process to address and communicate the uncertainty and variability inherent in a risk assessment..." ... Show more content on

Although there is no actual risk to the Sioux Falls headquarters from the bus terminal itself, a bus stop is to be found a few yards from the headquarters.
For the reason that the bus stop is very near the office, the likely risk of a bus collision is there, as also the hazard of a bomb exploding and/or
terrorism. To lessen the dangers, a recommendation that every office window be installed with security glass, protective bars installed to every external
window frame, and a steel protection entry screen be attached to the front entryway with a remote controlled security device.
Railroad Terminals. With a railway station within walking distance to McBride Financial Services, precautions must be made to mitigate derailing of
train cars. Railway cars contain a great deal of mass. When you combine that with velocity, you obtain force. A runaway rail car could obtain enough
force to destroy sections of McBride Financial Services. With that in mind, it is essential that McBride invest in precautionary measures. This could
include crafting railway dunes to prevent railway cars from colliding with McBride's structures.
Crime
In any city or town there is always criminal activity present (Albanese, 2003). Sioux Falls is no exception. For that reason, McBride must have
protection on its own from every kind of crime that could go on. This is to include deliberate actions taken towards McBride's properties and actions

Airthread Connections
Valuation of AirThread Connections
1. Methodological Approach to the Valuation
a) WACC (Weighted Average Cost of Capital)– When we are supposed to value AirThread Connections with the WACC valuation method we will
have to use the following steps: * Determine the unlevered free cash flows of the investment. * Compute the weighted average cost of capital with the
following formula:
* Compute the value with leverage, VL, by discounting the free cash flows of the investment using the WACC.
APV (Adjusted Present Value)– This method involves determining the value of a levered investment using the following steps: * Determine the
investment's value without leverage, VU, by discounting its free cash flows at the ... Show more content on Helpwriting.net ...
To do this we had to calculate the reinvestment rate w/o synergies and the return on capital (RoC). 1. Reinvestment Rate (2012): * (CAPEX + Working
Capital – Depreciations & Amortizations)/NOPAT * 2. Return on Capital: * Income before minority interest/(Equity + Long term debt– Minority
interest) * 3. Long–term growth rate: * * Using this growth rate we calculated a terminal value of $6782.88 and a PV(terminal value) of $4698.39: * *
b) The present value of AirThread's going concern value is $7956.85. We calculated this number using the following setup: PV of Terminal Value +PV
of Unlevered Free Cash Flow +PV of Interest Tax Shield + Value of Non
–Operating Assets =Going Concern Value
4. Valuation of AirThread
a) We calculated the total value of AirThread (before considering any synergies) by subtracting the value of the non–operating assets from the going
concern value. This gave us a total value of $6237.85.
b) When assuming that Ms. Zhang's estimates for synergies are accurate we can compute a new unlevered free cash flow looking like this: Unlevered

The Release 10 of LTE is the version that is approved by the ITU–R as an IMT Advanced technology and so is called LTE–Advanced. Release 10 of
the LTE that came out in March 2011 included carrier aggregation, enhanced downlink MIMO, uplink MIMO, enhanced ICIC and advanced relays.
Following the Release 10 came the Release 11 that incorporated enhanced carrier aggregation and additional intra–band carrier aggregation. In 2008 the
work associated with IMT–Advanced within the ITU–R circulated the detailed requirements and process via a circular letter. For 3GPP, LTE advanced
is not a new technology but is an evolutionary step in the ongoing development of LTE. To reach the IMT Advanced standards, wider bandwidth by
aggregation of various multiple carriers and evolved use of advanced antenna techniques in both downlink and uplink are the two main phenomenon
added in the Release 10 of LTE. The transmission scheme used for this technology is called OFDM (Orthogonal Frequency Division Multiplexing)
which is also prevalent in other radio–access technologies like WiMax and DVB broadcasting technologies. The work on LTE started in the late 2004
with the aim of providing new radio access technology that focused on packet switched data. The tasks include user/system, throughput, peak data
rates, spectral efficiency and user plane latency. ITU defined a set of requirements for IMT Advanced which include support for a

Airline Security After 9/11, 2001
Prior to September 11, 2001 there were a number of areas that needed to be addressed with regards to airline security. One of these areas relates to
the people hired by the airlines working as security personel. They did not have quality equipment to do thorough searches and were often unable to
detect possible threats on passengers and / or in their luggage. Passengers could easily carry dangerous items such as cutting devices, guns, bombs and
guns onto a plane.
Another area of concern before the terrorist attacks involved the actual security access areas of the terminals. The access control of the airports was not
as secure as it was intended to be. Criminals used badges and security cards to enter terminal buildings, to gain access to secure ... Show more content

The result was the passenger themselves being searched for weapons using scanners and screening techniques and equipment as well as their carry–on
luggage. Today passengers are costumed to more security checks, with body searches and checking carry–on luggage. In some parts of the world
vehicles are also checked for bombs upon arriving at the airport even if one is there just to pick up a loved on, each car is checked.
More searchers were not the only impact felt by travelling passengers. Many other regulations in terms of carry on and check–in luggage was changed.
Passengers are limited to one carry–on bag and one personal item (such as a purse or briefcase) on flights. When a passenger is checking in they are
required to identify themselves with official government identification such as an photo ID or drivers license. The identification is repeated a number
of times during the boarding process throughout the airport. Only passengers are allowed past the security gates and no friend or family are allowed to
greet the passenger at the boarding

Different Cooperative Communication Schemes Like Relay...
Abstract
In this survey, we will discuss about different cooperative communication schemes like Relay communication and Node cooperative system. Later on
we will perform comparison between conventional communication system and cooperative relay scheme based on power efficiency. We will also
discuss about various factors that will impact the efficiency of cooperative systems. We will conclude with applications of cooperativecommunication
in LTE advanced.
Cooperative communication
Technological convergence in telecommunications and networking has made it possible to bring voice, data (internet) and other multimedia services
over single channel. This has led to significant increase in network resource demands especially for wireless networks. To address these tremendous
network demands we need to use communication resources efficiently i.e., through Cooperative communications.
Cooperative communication system uses intelligent nodes or base stations that can consciously help other nodes to transfer information from the
source to the final destination with increased spectral efficiency and extended coverage in case of Cellular Base stations.
Cooperation in the communication networks can be realized using Relaying and Node Cooperative systems [1].
Relay communication system
In Relay system, first transmitter sends the data to the relay node and information received by the relay node is forwarded to next node and finally to
the destination receiver by following cooperation

SCADA and local area networks
Local area networks (LAN) are all about sharing information and resources. To enable all the nodes on the SCADA network to share information, they
must be connected by some transmission medium. The method of connection is known as the network topology.
Nodes need to share this transmission medium in such a way as to allow all nodes access to the medium without disrupting an established sender.
A LAN is a communication path between computers, file–servers, terminals, workstations, and various other intelligent peripheral equipments, which
are generally referred to as devices or hosts. A LAN allows access for devices to be shared by several users, with full connectivity between all stations
on the network. A LAN is usually owned and administered by a private owner and is located within a localized

In this document I will be detailing the different common network components which make up a network, connecting all the various devices together.
Each device has a separate use; however, some devices can replace or supplement others.
Devices can either be DTE or DCE. DTE, Data Terminal Equipmentis the source or destination of data. DCE, Data Communications Equipment
transmits the data along the network, connecting DTE's together. DCE works at the physical layer of the OSI model.

Routers
A Router forwards packets between different networks. As such they are connected to at least 2 networks, typically a LAN or WAN. A router is
located at the gateway of the network, which is the exit point for traffic on a network when it's destination is on a separate network. A common
example of the use of a router is in homes, of which connect devices in the household to the ISP and in turn, the internet.
A router uses headers and forwarding tables to identify the correct path to forward the packets it receives. Routers use ICMP to communicate between
each other to configure the best router between hosts.
A router is a DTE device, as it is the destination of all data leaving the network, and entering the network. And an end–point for the network.
Repeaters
A Repeater is used in a network to regenerate or replicate a signal. This is needed for long distance connections as the maximum distance of UTP
cabling is 100 metres. They can regenerate both analogue and digital signals. A Digital repeater will repair/ reconstruct the signal, however analogue
repeaters only amplify the signal, as such do not repair any distortion by any transmission loss.
A repeater can also relay data between subnetworks which use different protocols or data/ cable types.
A Repeater is a DCE device as it simply acts as a midpoint between DTE devices.

Managing Information Security Risk Of A Cyber Attack
Next, AAE will use the NIST SP 800–39: Managing Information Security Risk to generate a response for each risk.
Note that three of the risks are global risks; the data breach, terrorist, and rising fuel prices risks all stem from AAE's global marketplace activities.
According to the SP 800–39, AAE could utilize one of five strategies to respond to risk. It could choose to: 1) accept risks, 2) avoid risks, 3) transfer
/share the risks, 4) mitigate the risks, or 5) avoid the risks. Following are the responses and strategies generated by the register:
Risk 1 – Cyber Attack (Global_1):
Mitigate – C3J recommends AAE to use the defense in–depth approach to security to mitigate the risk of a cyber–attack. Essentially, defense in–depth
involves employing multiple security systems to protect company data. The concept works on the premise that if one system fails, another will be in
place to protect the data. Examples of defense in–depth safeguards include using encryption to protect data confidentiality, implementing solutions to
detect an attack, implementing solutions to backup and recover data, managing log files, and implementing a strong security awareness program. If a
breach occurs the Director of IT will notify the Executive Director and any affected parties before activating the AAE incident response plan (IRP).
Risk 2 – Rising aeronautical fuel prices (Global):
Transfer/share – Crude oil is the source of jet fuel; therefore, jet fuel prices are directly correlated to oil

Wireless Network Technology : Wimax
Wireless Network Technology: WiMAX This article focuses on one of the most used wireless technologies that uses wireless connections of data
that avoids expensive process of cables at home: WiMAX. WiMAX stands for Worldwide Interoperability for Microwave Access. Being a faster
version of Wi fi, this technology promises speed and large area coverage. It has been successfully proven to deliver the services to the customers (both
residential and commercial) economically. WiMAX has the capacity to serve high rates of data that might reach up to 74 Mbps when used a wide
spectrum of 20 MHz This has added to its brand value that attracts abound customers. WiMAX falls under the category of MAN technology that came
into existence in June 2001. However, the updated version came in 2011 that allowed this technology to provide up to 1 Gbits for particular stations.
There are two types of Wireless services provided by WiMAX:
1.Non–line–of–sight: The service of Non–of–Line–of Sign resembles Wi Fi service that uses quite low frequency array that ranges from 2 GHz to 11
GHz.
2.Line–of–sight. It has a higher frequency up to 66 GHz that allows eradicate the errors quite a bit with a larger capacity of data.

Taking a Look at Mangroves
1.0 Introduction "A mangrove is a tree, shrub, palm or ground fern, generally exceeding one and a half metres in height, which normally grows above
mean sea level in the intertidal zone of marine coastal environments and estuarine margins. A mangrove is also the tidal habitat comprising such trees
and shrubs" (Mangroves defined, n.d.). To survive in an intertidal environment, they must be able to tolerate a broad range of salinity, temperatures and
moisture levels. In an environment with such low oxygen levels, different species of mangroves use different adaptations in an effort to get as much
oxygen as possible.
Different species of mangroves gather oxygen in different ways, some use roots that protrude from the ground called peg roots, these peg roots,
which are covered in lenticels, can reach up to 30cm in height and allow the plant to exchange gas, as an extension of the roots, which run through the
ground, this allows the plant to absorb nutrients from the soil as well, which is a common adaptation in all species of mangroves. Other species are

Information Technology In Law Enforcement
When I began my career in law enforcement, I always wondered what it was like to be in law enforcement back in the days. Without any technology to
fall back on, I wonder how difficult it was to be in law enforcement profession. Sometimes I ask myself how difficult it would be for me to accomplish
my tasks without cell phones, computers or fingerprints readers. How much did information technology contribute to law enforcement? Or how much
has law enforcement career changed, due to the rise of information technology and its contribution to law enforcement profession. In this assay, I will
elaborate the key factors that have changed law enforcement, due to the developments in information technology. How the advances in the information
technology, such as cell phones, Mobile Data Terminal(MDT) and use of body warn cameras affected law enforcement and prompted new evolution in
this profession.
In today's day and age, cell phones represent an instrumental tool for law enforcement. For instance, during patrol I could use my work cell phone
to search for the directions to my call. I could download multiple apps, to reference from if I need to look up the vehicle code or penal code
violations. One main benefit to having access to my cell phone at work, is that I could request my back up if I am in the area where I do not have
good radio reception. The use of cell phones in law enforcement is essential, because it also provides direct communication between the officers and
citizens.

Essay On Ports And Terminal
3.3 Port and Terminal A port is defined as an area on both land and water, whether on the sea or river, that provides facilities for shipping vessels to
load and unload their cargo. This area, contained within 'port limits', will have been established over years of increasing or declining trade patterns
and therefore is defined as the 'human set limits'. There may be several harbors and/or terminals within the port limits. While a terminal is defined as a
single man–made facility that may have several berths, that handles vessels and possibly more than one type of vessel or cargo. The rapid growth of
international and local trade in Maritime sector underline the importance of ports and terminal in connecting the ship with the land to move the people
or cargo. Ports and terminal are recognized as vital contributors in facilitating Malaysia's trade. Since Malaysia is a nation surrounded by a sea area
much larger than its land mass, development towards ports and terminal is essential in providing an excellent infrastructures and facilities to traders.

Towards meeting this objective, the Economic Planning Unit (EPU) in the Prime Minister's Department commissioned a study in 1987 to draw up a
blueprint for a national port policy. The study, outlining policy recommendations and action plans to enhance the growth and development of ports in
the country, set the pace for rapid port development in the country. Central to the policy was port privatization and the establishment of a national load
centre featuring modern terminal facilities and large cargo volumes to attract large container

U.s. Maritime Transportation Security Act
Massport has enacted several policies and procedures to tighten security and better secure their various waterfront terminals. These policies include, but
may not be limited to:
1. Transportation Worker Identification Credential: Massport has mandated the use of the Transportation Worker Identification Credential (TWIC) and
Massport Maritime Credentials for all workers entering Conley Terminal and Black Falcon Cruise Terminal. Required by the Maritime Transportation
Security Act, TWIC is a threat assessment tool used to vet workers who require unescorted access to secure maritime facilities, vessels and other critical
assets (e.g. cyber systems). Types of workers include, but may not be limited to, U.S. Coast Guard documented mariners, port and terminal operators,
truckers, equipment maintenance personnel and port security personnel. Following a successful background check, workers are issued an identification
which contains key employee information including name, a photo and biometric data. Personnel requesting a Massport Maritime Credential must
present a TWIC card at the time of their request. Massachusetts currently supports five TWIC enrollment locations. They are located in Pocasset,
Brockton, Boston, Worcester and Springfield.
2. Non–Intrusive Inspection Program: Safeguarding U.S. borders requires the use of available and emerging technology to detect contraband and
radiological material, deny entry when warranted and deter criminal or terrorist
