Confirms Retinal Origin of Orientation Map
Results section Orientation selectivity is one of the properties of neuron in primary visual cortex that
a neuron response maximally when particular orientation of stimulus is given. The orientation map
is a map showing the orientation preferences of cortical neurons in primary visual cortex. This
research provides evidences for support of the theory posit that the orientation selectivity map is a
product of a Moiré interference pattern that originates in retinal ganglion cells. This paper shows
that interactions between excitatory neurons and inhibitory neurons in neuron network modeled by
NEURON simulator having a Moiré interference pattern which results in an orientation selectivity
map on the primary visual cortex.

A host in an Ethernet network can communicate with another host,only if it knows the Ethernet
address (MAC address) of that host.The higher level protocols like IP use a different kind of
addressing scheme like (IP address) from the lower level hardware addressing scheme like MAC
address.ARP is used to get the Ethernet address of a host from its IP address.ARP is extensively
used by all the hosts in an Ethernet network.In this case there is already an entry for this IP
address,Meaning this host already knows the MAC to IP address mapping for this destination so
there is no need to send out an ARP request instead it will send the ICMP packet directly to

After I viewed and heard that judge decision on this case, my position is in favor of the defendant.
The formation of a contract is achieved where there is an offer and acceptance between the
contracting parties. An acceptance is sometimes referred to as "meeting of the minds" that involves
the exchange of consideration, either a promise to act, provide goods, services or money. Relative to
this case, a valid offer was made by a plaintiff. For an offer to be valid, there should be a
manifestation or indication of present contractual intent, a certain definite terms that is expressly
stated and a communication of an offer to the offeree. Consequently, when the offeror (plaintiff) had
called and had left a message regarding the date, time and payment arrangement of the recording
project to the defendant, the plaintiff's action satisfies the requirements of a valid offer (Mallor,

at the studio may established and implied acceptance, yet there was no meeting of the minds on both
parties that would affirm on the compensation of the recording project. An acceptance can be
implied by action. But if the parties have not reached a meeting of the minds, then there is no

However, if the power network remains close to fo (±0:2–0:5Hz[2]), using both the constant

Frequency is inversely proportional to time, F = T1 , so Fc = N1∆t, where Fc is the sampling
frequency. The frequency window is centered around zero and includes positive frequencies up to
half the maximum frequency, F2c and the 91.3. An Overview of Transient Solution Methods for the
Electrical Network complex conjugates of these frequencies. F2c is called the Nyquist frequency
and it is the maximum frequency that can exist in the frequency window[38]. 2. It takes
approximately 8–10 samples to accurately represent one period of a sinusoidal signal [14].
Therefore, the time–step needed to discretize the continuous–time sinusoidal signal using N=10
samples and FNy = F2c is Eq.(1.12): ∆t = 1 10 × Fc or ∆t = 5 ×1FNy (1.12) For transient stability
studies around 60Hz, the EMTP will require a time–step of approximately 1ms to solve the
electrical network (Eq.(1.12)). In addition, the EMTP time–step is limited by the travelling time of
the waves in the transmission lines. If the transmission lines are modelled with the constant–
parameter[14] or frequency–dependent[18] line models, the time–step may be in the order of the µs.
Although the EMTP is highly accuracy, its small time–steps increase the simulation time, which is a
disadvantage in large systems. Because the phasor solution does not depend on the time–step in the

technologies operate at speeds up to 10Gb. This is the data transfer rate. IEEE has projects
investigating the standardization of 40 and 100Gb.
Wide area network
A wide area network (WAN) is a computer network that covers a large geographic area such as a
city, country, or spans even intercontinental distances, using a communications channel that
combines many types of media such as telephone lines, cables, and air waves. It usually uses
transmission facilities provided by common carriers, such as telephone companies. WAN
technologies generally function at the lower three layers of the OSI reference model: the physical
layer, the data link layer, and the network layer.
The Internet is considered the largest network in the world. The PSTN (Public Switched Telephone

36. Connectivity And Network Security : Connectivity
Connectivity and Network Security
1. Introduction In this paper, we will look into three topics: connectivity, Menger 's theorem, and
network flows to further understand the application of connectivity such as network systems. In
graph theory, connectivity is an important topic and can be applied to many different areas. By
considering the connectivity of the graph(network system map), we will be able to see clearly the
problems of the graph(the system), such as low–connectivity that may lead to the vulnerability of an
attack. Once we know the properties of the graph(the system), we can determine or change how the
graph is or should be.
2. Connectivity
A graph G is connected if for all pairs u, v ∈ G, there is a path in G from u to v. Note that it suffices
for there to be a walk from u to v. [Graph Theory, p. 9] A walk in G is a sequence of vertices
v0,v1,v2,...,vk, and a sequence of edges (vi, vi+1) ∈ E(G). A walk is a path if all vi are distinct.
[graph_theory_notes, p. 8] Figure 1 [Graph Theory, p. 9]
A (connected) component of G is a connected subgraph that is maximal by inclusion. We say G is
connected if and only if it has one connected component. [Graph Theory, p. 9]
Figure 2 [Graph Theory, p. 9]
2.1 Vertex connectivity
A vertex cut in a connected graph G = (V,E) is a set S ⊆ V such that GS:= G[V S] has more than one
connected component. A cut vertex is a vertex v such that {v} is a cut. [Graph Theory, p. 17]

42. E Commerce : A Network Of Intricate Commercial Activities
Electronic Commerce has been given several definitions. In its largest sense, E–Commerce can be
defined as the whole commercial transactions, whether national or transnational, carried out thanks
to electronic processing and transmission of data: texts, sound, and images. This consists in applying
the information and communication technology (IT) to commercial activities: conception and
production; while involving a certain number of public or private agents in direct or indirect forms.
Today E–Commerce has become a network of intricate commercial activities at the planetary level.
E–Commerce facilitates the distribution and the exchange of goods and services. The ranges of
consumer goods are very broad. One can electronically sell ... Show more content on

The challenge of E–Commerce consists in elaborating an adapted prescriptive, a normative
framework i.e. taking into consideration the environment where the paper document, conceived as
the privileged and sometimes compulsory vector of the will of parties can no longer play its
traditional role. The matter consists, in a way, in achieving a certain conciliation between the
principles of the freedom of commerce and the need to facilitate E–Commerce. Thus, it consists of
setting up flexible rules while keeping in mind the need for safety and protection of the consumer.
Some authors today speak about the Lex Electronica. The Lex Electronica would correspond to a
number of the informal legal rules applicable in the framework of E–Commerce. I1 would have
institutional sources (international conventions, codes of conduct of business, standard contracts)
and substantial sources consisting of the contractual practices and the general principles of law and
practices. At the institutional level, several efforts have been deployed in order to regulate E–
Commerce by the international authorities such as WIPO, WTO, ODCE, UNCTAD, UNCITRAL
and the European Council. One can mention, in particular, the standard Law on E–Commerce
adopted by UNCITRAL on January 30, 1997. No international organisation before UNCITRAL had

Isaac Ozimov, or Isaac Asimov was born on January 2, 1920 in what is now called Smolensk Oblast,
Russia to Judah and Anna. His family immigrated to the United States in 1923 and settled in
Brooklyn, New York. ("A&E Networks Television" Web.) Isaac Asimov grew up thinking that his
birthday was on September 7, 1919 because his mother wanted him to be able to go to school a year
earlier than he should. No one ever seemed to notice that he was younger than his classmates,
probably because of his great intelligence. ("A&E Networks Television" Web.) Isaac proved that he
was smart very early in life. By age five he could read and speak two languages, English and
Yiddish. ("IMDb" Web.) He was placed on the advanced track in school and graduated high school
at age fifteen. By age eighteen, he had sold his first story "Marooned off Vesta" to be ... Show more

He would later go back and get his PHD in the same subject. ("A&E Networks Television" Web.)
During this time he still found time to write and publish his first novels Pebble In the Sky and I
Robot in 1950. ("A&E Networks Television" Web.) He married his first wife, Gertrude Blugnerman
in 1942 and had two children, David, who was born in 1951, and Robyn, whom was born in 1955.
("Internet Accuracy Project" Web.) Asimov only stayed married to Gertrude for 21 years. He
divorced her in 1973 and married Janet Jepson, a long time acquaintance that same year ("A&E

hundred stories ("Internet Accuracy Project" Web.) His life was cut short when he died on April 6,
1992 in New York City from heart and Kidney failure. His death was likely the result of

The computer network is computers and other devices have to be connected so they can share data
and hardware or software resources. In 1969, the University of California at Los Angeles, the
Stanford Research Institute, the University of California at Santa Barbara and the University of Utah
were all connected to be part of the Advanced Research Project Agency Network (ARPANET)
project. This network has evolved to become the internet now. The networks are used to
communicate by email, video chat (video conferencing), and instant messaging. It enables many
people can share a single hardware device like a printer or scanner and files can be shared. Software
or operating on remote systems can be shared. The types of networks are local area networks
(LAN), personal area networks (PAN), home area networks (HAN), wide area networks (WAN),
campus networks, metropolitan area networks (MAN), enterprise private networks, internetworks,
backbone networks (BBN), global area networks (GAN), and the internet. Throughout the years

53. Wireless Sensor Networks ( Wsn ) Is A Key Innovation For...
Abstract–Wireless sensor networks (WSN) is a key innovation for the wireless network technology.
It generally has a large number of sensor nodes with a power unit, a sensing unit, a processing unit,
a storage unit, and a wireless transmitter & receiver. They are more vulnerable to attack then wired
ones due to its nature and resources limitations. So as to overcome this security problems we can
different types of Key Distribution and Hierarchical WSN. This paper gives more solutions to all
problems in security issues of the Networks.
Keywords–wireless sensor network, distributed wireless sensor network, hierarchical wireless
sensor network, key distribution, key pre–distribution, pair–wise keys, group–wise key, network
keying.

(ii) Resource limitations on sensor nodes. (iii) Lack if fixed infrastructure. (iv) High risk of physical
attacks. (v) Unknown network topology prior to deployment. This is why it is tough to secure WSN.
II. TERMS, DEFINITIONS AND NOTATIONS
Terms used in this paper are as follows:
–key: symmetric key which is used to secure communication among two sensor nodes.
–pair–wise key: key which is used to unicast communication between a pair of sensor nodes.
–group–wise key: key which is used to secure multicast communication among a group of sensor
nodes .
–network–wise key: key which is used to secure broadcast messages.
III. NETWORK MODELS AND SECURITY REQUIREMENTS OF WSN
There are generally 2 types of architectures in WSNs. (i) Hierarchical and (ii) Distributed. In a
Hierarchical WSN, A base station is a gateway to another network with some other base station to a
data processing and storage center, or a human interface node point. Base point takes data from
sensors send it to processing unit and that data is sent to the human interface node point. Therefore,
base stations are used as key distribution centers as they are connected every other node in network.
Sensor nodes form a dense network in form of clusters where a cluster of sensors lying in a specific
area may provide similar or close readings of data. Not all node gets the power from power unit few
sensor nodes depend on the ad hoc communication to reach base stations.

55. What Is SDN Controller
The SDN layer essentially acts a virtual software switch or router in place of (or in conjunction
with) the physical network devices. Software from outside the devices takes over the job, instead of
software embedded in the routers and switches managing the traffic. The network layout, or
topography, is no longer rooted in the physical. Instead, it 's flexible and adjustable to the systems'
needs on the fly. SDN promises to solve both cost of labor performing manual maintenance and
administrative tasks in one single blow to the status quo. Traffic engineering problem for SDN
controller is to route the traffic in such a way that the delay and packet loss at link are minimized. In
existing scenario SDN controllers are deployed incrementally. In proposed system SDN controllers
are deployed in tree like structure such that lower level controller is controlled by upper level
controller so that all the network is controlled by single SDN controller centrally. Making possible
to centralized control over the global view of network with improved architecture will be
considered. Keywords – Mininet, OpenFlow, Software Defined Networking , SDN Controller. I.
INTRODUCTION Now a day's it is important to have centralize control over the resources rather
than distributed one. In current network architectures, the network devices are bundled with a
specialized control plane and various specialized features. This essentially binds us with the features

57. The Ring Signature Scheme
Deniable ring signature: The ring signature scheme which has the property of anonymity revocation
is known as deniable ring signatures. This was first proposed by Susilo and Nu . In this ring
signature scheme, the verifier can interact with the signer or entities to confirm that the signer or
entity has signed the signature with zero knowledge interactive proof. In this signature scheme, any
signer cannot shift blame to other entities. Denial ring authentication is a combination of ring
signatures and deniable authentication. Digital signatures provides authentication of messages thus
providing non–repudiation of messages. In most of the applications, non–repudiation is one of the
desirable properties, but in some applications it may not be. Inspired by such requirements Naor
introduced Deniable ring signature scheme in 2002. In such ring authentication scheme, the verifier
can be convinced that a entity of an adhoc group of participants is authenticating a message m, by
not disclosing the identity information of the signer entity. It is also not possible for the verifier to
convince any third party entity that message m is authenticated. This has been found in a number of
applications. The Deniable ring signature scheme has the following properties:
1.It should be a good authentication scheme if no adversary can force a receiver to accept a message
for which it is not the intended receiver. So it should be forgery resistant.
2.The authentication is done in way of zero

The Great Chicago Fire: A City in Flames
Third Draft
Hope Hudson How would someone react if they woke up and their house was covered in flames, or
what if the town they lived in was being burnt to the ground? Millions of people have had to deal
with the effects of fire. Across America there have been too many fires to count. In the city of
Chicago, 1871, thousands of people were affected by a fire. The Great Chicago Fire will always be
remembered, one of the worst in history. When society imagines fires they see devastation and ruin,
and what people saw in Chicago, once the flames ceased, was exactly that. The Great Chicago Fire
destroyed many homes and tore apart the lives of many civilians; however, American patriots rose
up to rebuild the city to an even more epic place. Frederick Francis Cook once said, "We of the

a present without a past"(Discovery Education). In the city of Chicago, the year 1871, there had

though Catherine did not agree that the fire started in her barn ("The Chicago Fire") (A & E

Discusses the Differences Between 'Implementation' and 'Policy' and Describes the Importance of
Their Separation
Management defines information security policies to describe how the organization wants to protect
its information assets. After policies are outlined, standards are defined to set the mandatory rules
that will be used to implement the policies. Some policies can have multiple guidelines, which are
recommendations as to how the policies can be implemented. Finally, information security
management, administrators, and engineers create procedures from the standards and guidelines that
follow the policies. ... Show more content on Helpwriting.net ...
Similar to policies for appropriate use of the telephone, organizations need to define appropriate use
of e–mail.
Organizational polices are needed to establish general guidance in such areas as: The use of e–mail
to conduct official business
The use of e–mail for personal business
Use software that follows Internet e–mail protocols and conventions religiously. Every time an
online service gateways its proprietary e–mail system to the Internet, there are howls of protest
because of the flood of error messages that result from the online service's misbehaving e–mail
servers.
Compares Policy Differences Between Users Who Work Remotely or Use Wireless
The Ethernet lines run from the network switch, sometimes through a patch panel, out of the
communication room and connect to the VoIP phones and other IP devices. Adding PoE enables
devices to be powered over the same Cat 5 cabling infrastructure, providing the most cost–effective
solution. Allows users too freely and safely mix legacy and PoE–compatible devices on their
network. PoE technology is designed in a way that does not degrade the network data
communication performance or decrease network reach. There are two ways to implement Power

Abstract
CNX Nifty being an important barometer to indicate country's growth has always been followed
with lots of interest from both academia and industry. Now, CNX Nifty could be predicted or not on
a random basis gives rise to many a questions. This sounds redolent with any predictive modeling
though with a certain degree of accuracy in built in to the system. The major point of consideration
is that predictive modeling could be done by various measures and mechanisms. In predictive
modeling Multiple Adaptive Regression (MARS), Classification and Regression Trees (CART),
Logistic OLS or Non Linear OLS could be used. Here in this study the researcher has utilized
Neural Network as a "Predictive Modeler" to predict CNX Nifty closing on certain random time
zones under consideration.

79. The Training Of A Neural Networks
In order to have a better understanding of the mechanism used in the prediction process, we need to
know what are the stopping conditions, as this process involves a finite number of iterations known
a priori. It has been previously proved one of the problems that occur during the training of a neural
networks is overfitting towards the input data, which generates low quality predictions [56]. In order
to reduce this tendency, the early stopping criteria has been formulated. This involves dividing the
input set in three subsets [57]: –training set, used to estimte the weights; –testing set, used to assess
the prediction sample and –validation set, which is an accuracy indicator of the prediction sample,
although it is not used during the ... Show more content on Helpwriting.net ...
Application using neural networks for the real Gross Domestic Product (GDP) prediction This is an
empirical example which has the role of highlighting the differences between a neural network and a
linear regression model. Lamy Robert estimated a linear regression model to predict the growth of
real GDP in Canada [59]. His model explains 82% of the GDP variation in the period 1978–1998.
The coefficient obtained are statistically significant so, he the model can be used to predict the
values of the GDP for different periods. His model contains six independent variables, which are:
R_(t–1)–is the quarterly growth of the Canadian Financial Index at t–1; F_t–is the employment
growth rate at time t; F_(t–1)–is the employment growth rate at t–1; B_t–is the consumer confidence
index; d_(t–9)–is the first difference of the long–term real interest rate at time t–9 (9 month before
time t); d_(t–3)– is the first difference of the government budget balance as a share of GDP, at time
t–3 (3 months before time t). Four dummy variables have been included in the model to control four
periods (quarter 1 in 1980, quarter 1 in 1981, quarter 4 in 1986 and quarter 3 in 1991). The linear
regression model was estimated based on 62 observations and is given by: 〖GDP〗_t=–

variables. The neural

81. Telecommunication Companies Use Nokia 's Gsm Network
GSM ARCHITECTURE
INTRODUCTION
Most of the top telecommunication companies use Ericsson's GSM network including Vodafone
Delhi. GSM R9 network, a multi service network has the ability to accommodate a variety of
networks. For the operator, continuity of services, end client application portfolios and significant
cost reductions in transmission, operation and support are the implications of GSM R9. GSM is an
advanced TDMA framework upgraded for full duplex voice telephony.
The network is partitioned into:
Switching systems (SS)
Base station system (BSS)
Operation and support system (OSS)
The entire system is made up of every system's functional units.
NODES
1. Switching system
Mobile services switching centres
It plays out the system telephony switching functions as well as controls calls to and from other
telephony and data systems, such as the PSTN and PLMN. In Ericsson's GSM system, the VLR is
constantly incorporated with the MSC to shape a MSC/VLR to use internal signalling.
Visitor location register
The visitor location register is a database containing information about all the MSS that as of now
are located in the MSC service area. It has temporary subscriber information that the MSC requires
to provide service for visiting subscribers. The VLR can be seen as a distributed BHLR. When a
mobile station roams into a new MSC service area, the VLR associated with that MSC requests data
about the MS from the HLR and stores it. The VLR has all the required
