Strategies and Metric for Resilience in Computer Networks
The document discusses strategies and metrics for resilience in computer networks. It proposes a resilience factor to measure a network's ability to withstand targeted attacks. It also proposes two strategies, called PropAdd and PropRew, to improve network resilience by preferentially adding links or rewiring existing links based on centrality metrics. Experimental results on real network topologies confirm the effectiveness of the proposed approach.

Open Elective MSE.pptx
A network connects devices through communication links. A node can be a computer, printer, or other device capable of sending and receiving data from other nodes. There are different types of network topologies that connect nodes in different configurations, such as a star, mesh, ring, or bus topology. Networks also use various transmission media like twisted pair cable, coaxial cable, or fiber optic cable to transmit signals between nodes. Wireless networks also connect nodes using radio waves without physical cables. Network protocols and standards define rules for communication between nodes to ensure interoperability.

Modeling, Analysis, and Design of Multi-tier and Cognitive Cellular Wireless ...
Abstract: Multi-tier architecture with small cells such as femtocells, picocells, macrocells, and metrocells, overlaid with traditional macrocells is considered as a promising option to improve the network coverage and capacity of the next generation cellular wireless networks. Also, in such multi-tier networks, cognitive radio concepts will likely to be used by these small cells to improve the radio spectrum utilization. In this context, modeling, analysis, and design of multi-tier and cognitive cellular networks is increasingly attracting the attention of the research community. Recently, stochastic geometry models have been shown to provide tractable yet accurate performance bounds for multi-tier and cognitive cellular wireless networks. Given the need for interference characterization in multi-tier cellular networks, stochastic geometry models provide high potential to simplify their modeling and provide insights into their design. In this seminar, I will present a review of the stochastic geometry models for single-tier as well as multi-tier and cognitive cellular wireless networks. I will also present a taxonomy based on the target network model, the point process used, and the performance evaluation technique. To this end, I will discuss the open research challenges and future research directions.
Prof Ekram Hossain
Computer Network Topology By Team_Culture Crusade (Dept . of Sociology)
Network topology refers to the physical and logical arrangement of devices within a computer network. Understanding different network topologies is crucial for designing efficient and reliable communication systems.
Computer networks
Computer networks allow computers to share resources by connecting nodes using telecommunication technologies over digital interconnections. Nodes on a network include devices like personal computers and servers that are identified by hostnames and network addresses. The ARPANET was a pioneering computer network developed in the late 1960s that served as a forerunner to the modern Internet. Computer networks aim to enable resource sharing, improve performance and reliability, allow scalability, and enhance security. Key hardware components of networks include servers, clients, transmission media, and connecting devices. Software components comprise networking operating systems, protocols, and protocol suites. Common cable types for connecting devices are coaxial, twisted-pair, and fiber-optic cables.

A survey on cost effective survivable network design in wireless access network
In today’s technology, the essential property for wireless communication network is to exhibit as a
dependable network. The dependability network incorporates the property like availability, reliability and
survivability. Although these factors are well taken care by protocol for wired network, still there exists
huge lack of efficacy for wireless network. Further, the wireless access network is more complicated with
difficulties like frequencies allocation, quality of services, user requests. Adding to it, the wireless access
network is severely vulnerable to link and node failures. Therefore, the survivability in wireless access
network is very important factor to be considered will performing wireless network designing. This paper
focuses on discussion of survivability in wireless access network. Capability of a wireless access network to
perform its dedicated accessibility services even in case of infrastructure failure is known as survivability.
Given available capacity, connectivity and reliability the survivable problem in hierarchical network is to
minimize the overall connection cost for multiple requests. The various failure scenario of wireless access
network as existing in literature is been explored. The existing survivability models for access network like
shared link, multi homing, overlay network, sonnet ring, and multimodal devices are discussed in detail
here. Further comparison between various existing survivability solutions is also tabulated.

The Reading:
In Covington, Louisiana, two police officers became certified as cultural diversity trainers. By
taking on this role, they have committed to working with other members of the police department
to help improve relations between police and the surrounding communities to prevent the deaths
of unarmed civilians. Sgts. Jake Lehman and Detective Kevin Collins went to Norman,
Oklahoma, where they became certified instructors through the Racial Intelligence Training &
Engagement (RITE) academy. RITE seeks to assist police officers in learning ways to
understand their biases and improve their communication skills by focusing on emotional and
social intelligence, ultimately seeking to improve their ability to deescalate charged situations.
The idea is to de-escalate whenever possiblewhich in turn will reduce use of force incidents, their
police chief Tim Lentz notes.
Many police and public safety departments across the United States are seeing a renewed push to
implement or improve diversity training programs because of the contentious nationwide debate
surrounding the use of excessive force by police against minorities. For example, a settlement
between the U.S. Justice Department and the city of Ferguson, Missouri, required the hiring of a
monitor to analyze patterns of arrest and force, diversity training for police, and the use of body
cameras. These changes come in the wake of the tragedy in which Michael Brown, an 18-year-
old unarmed Black man, was fatally shot in 2014.
Overall, diversity training can take many shapes and forms. But how effective is it at improving
an understanding of diversity and reducing prejudice? A large-scale review of over 250
independent studies found that trainees react positively to diversity training and that it appears to
be quite effective at improving the way trainees think about diversity, although it affects
behavior to a lesser degree. Overall, diversity training worked best when accompanied by other
diversity management approaches that focused on both diversity skill development and
awareness and when continuously implemented over time (instead of just a one-time training
exercise). Many have found that the most effective programs engage people in working toward
diversity goals, increase contact among various demographic groups, and draw on peoples desire
to help one another.
On the other hand, it appears as if many are not sold on the effectiveness of diversity training.
For example, some note that there is a large obstacle to overcome: We are wired to make quick
interpretations and automatic judgments. According to esteemed behavioral economist Daniel
Kahneman, Trying to outsmart bias at the individual level is a bit of a fools errand, even with
training. We are fundamentally overconfident... so we make quick interpretations and automatic
judgments. Some diversity programs have failed because they too often attempt t.

Read above Case Study and answer below questions:
Assuming that you are a Freelance Project and Procurement expert, you have been approached
by Chandran for a fee to help him deal with his current predicaments. Help him to find his way
out to salvage the project that is slowly slipping from his control with the deadline fast
approaching.
TASKS:
Respond in writing by addressing the following in the report:
(a) His position as a contractor and what is expected from the client.
(b) A clear analysis of his case within the project contractual framework.
(c) Based on the above, make recommendations on the way forward and justify your
recommendations. The Cable Contract Chandran was confused as the project he had worked so
hard on, was turning out to be a quagmire. He searched for a way out of the predicament he was
in. A graduate from BMS College of Engineering, Bangalore (BMSCE), Chandran was a
qualified and licensed electrical contractor. He had recently secured a tender contract at a
premier government organization valued at Rs 2.7 lakh. The tender was for 'Replacement of
Faulty Cable to Feeder Pillar No 7 for providing power supply to the research blocks, hostels,
cabins etc., at National Technical Networks and Laboratories Limited (NTNL) Bhavan,
Bangalore - 16'. The contract was floated on a turnkey i basis by the Engineering and
Technological Maintenance Unit (ETMU) of NTNL on behalf of its Director for its Bangalore
Centre. ETMU was one of the many different departments within NTNL that routinely called for
tenders. The tender was dated October 25, 2001 and the work order was issued to Chandran on
the November 12, 2001. The time allowed to complete the project was 21 days including
weekends. No exceptions were permitted as the project was floated on an urgent and priority
basis. It was indeed a remarkable achievement for Chandran as this was his first assignment in an
organization of that repute. As a new comer to the profession he had earlier undertaken many
works that were sub-contracted ii to him by other contractors and for small organizations, but
had never on his own secured any contracts from bigger organizations like NTNL. The tendering
process at NTNL was the same as that of many government organizations. The tenders valued
below Rs 5 lakhs were non-transferable and of 'single cover' system. A bidder needed to submit
all the requested details in a single sealed cover that included the price quote. These tenders did
not require much experience from the bidders although the bidding contractors both civil and
electrical or any one of them, were required to possess government-issued licenses to execute the

REVIEW ON MANET: EVOLUTION, CHALLENGES AND USES
REVIEW ON MANET: EVOLUTION, CHALLENGES AND USESInternational Journal of Technical Research & Application
This document discusses the history, challenges, and applications of mobile ad hoc networks (MANETs). It describes how MANETs evolved from early packet radio networks developed in the 1970s. Key challenges for MANETs include dynamic topology changes, asymmetric wireless links, and lack of a centralized administration. However, MANETs also enable applications for military communications, disaster recovery, device networking, internet sharing, and wireless sensor networks by allowing devices to self-configure into a network without any infrastructure. While progress has been made, many technical challenges remain in fully realizing the vision of seamlessly integrating MANETs with other networks.Artificial and Augmented Intelligence Applications in Telecommunications - Fr...

computers. These personal computers made it possible to maximize individual
productivity. However, most current hardware and software technological developments
have been aimed at maximizing group productivity. Increasingly, personal computers
are networked together to enable communication between users and to facilitate
sharing of data and resources. This chapter is aimed at providing a basic understanding
of a range of telecommunications concepts including local area and wide area networks.
We also discuss some recent communications technologies affecting business such as
client/server systems, the Internet, and electronic data interchange. Almost all
computer systems in organizations today are networked, and these networked
computer systems invariably house a wealth of accounting information. It is therefore
important for accountants to have a working knowledge of data communications and
networking concepts.

Open Elective MSE.pptx
A network connects devices through communication links. A node can be a computer, printer, or other device capable of sending and receiving data from other nodes. There are different types of network topologies that connect nodes in different configurations, such as a star, mesh, ring, or bus topology. Networks also use various transmission media like twisted pair cable, coaxial cable, or fiber optic cable to transmit signals between nodes. Wireless networks also connect nodes using radio waves without physical cables. Network protocols and standards define rules for communication between nodes to ensure interoperability.

Modeling, Analysis, and Design of Multi-tier and Cognitive Cellular Wireless ...
Abstract: Multi-tier architecture with small cells such as femtocells, picocells, macrocells, and metrocells, overlaid with traditional macrocells is considered as a promising option to improve the network coverage and capacity of the next generation cellular wireless networks. Also, in such multi-tier networks, cognitive radio concepts will likely to be used by these small cells to improve the radio spectrum utilization. In this context, modeling, analysis, and design of multi-tier and cognitive cellular networks is increasingly attracting the attention of the research community. Recently, stochastic geometry models have been shown to provide tractable yet accurate performance bounds for multi-tier and cognitive cellular wireless networks. Given the need for interference characterization in multi-tier cellular networks, stochastic geometry models provide high potential to simplify their modeling and provide insights into their design. In this seminar, I will present a review of the stochastic geometry models for single-tier as well as multi-tier and cognitive cellular wireless networks. I will also present a taxonomy based on the target network model, the point process used, and the performance evaluation technique. To this end, I will discuss the open research challenges and future research directions.
Prof Ekram Hossain
Computer Network Topology By Team_Culture Crusade (Dept . of Sociology)
Network topology refers to the physical and logical arrangement of devices within a computer network. Understanding different network topologies is crucial for designing efficient and reliable communication systems.
Computer networks
Computer networks allow computers to share resources by connecting nodes using telecommunication technologies over digital interconnections. Nodes on a network include devices like personal computers and servers that are identified by hostnames and network addresses. The ARPANET was a pioneering computer network developed in the late 1960s that served as a forerunner to the modern Internet. Computer networks aim to enable resource sharing, improve performance and reliability, allow scalability, and enhance security. Key hardware components of networks include servers, clients, transmission media, and connecting devices. Software components comprise networking operating systems, protocols, and protocol suites. Common cable types for connecting devices are coaxial, twisted-pair, and fiber-optic cables.

A survey on cost effective survivable network design in wireless access network
In today’s technology, the essential property for wireless communication network is to exhibit as a
dependable network. The dependability network incorporates the property like availability, reliability and
survivability. Although these factors are well taken care by protocol for wired network, still there exists
huge lack of efficacy for wireless network. Further, the wireless access network is more complicated with
difficulties like frequencies allocation, quality of services, user requests. Adding to it, the wireless access
network is severely vulnerable to link and node failures. Therefore, the survivability in wireless access
network is very important factor to be considered will performing wireless network designing. This paper
focuses on discussion of survivability in wireless access network. Capability of a wireless access network to
perform its dedicated accessibility services even in case of infrastructure failure is known as survivability.
Given available capacity, connectivity and reliability the survivable problem in hierarchical network is to
minimize the overall connection cost for multiple requests. The various failure scenario of wireless access
network as existing in literature is been explored. The existing survivability models for access network like
shared link, multi homing, overlay network, sonnet ring, and multimodal devices are discussed in detail
here. Further comparison between various existing survivability solutions is also tabulated.

The Reading:
In Covington, Louisiana, two police officers became certified as cultural diversity trainers. By
taking on this role, they have committed to working with other members of the police department
to help improve relations between police and the surrounding communities to prevent the deaths
of unarmed civilians. Sgts. Jake Lehman and Detective Kevin Collins went to Norman,
Oklahoma, where they became certified instructors through the Racial Intelligence Training &
Engagement (RITE) academy. RITE seeks to assist police officers in learning ways to
understand their biases and improve their communication skills by focusing on emotional and
social intelligence, ultimately seeking to improve their ability to deescalate charged situations.
The idea is to de-escalate whenever possiblewhich in turn will reduce use of force incidents, their
police chief Tim Lentz notes.
Many police and public safety departments across the United States are seeing a renewed push to
implement or improve diversity training programs because of the contentious nationwide debate
surrounding the use of excessive force by police against minorities. For example, a settlement
between the U.S. Justice Department and the city of Ferguson, Missouri, required the hiring of a
monitor to analyze patterns of arrest and force, diversity training for police, and the use of body
cameras. These changes come in the wake of the tragedy in which Michael Brown, an 18-year-
old unarmed Black man, was fatally shot in 2014.
Overall, diversity training can take many shapes and forms. But how effective is it at improving
an understanding of diversity and reducing prejudice? A large-scale review of over 250
independent studies found that trainees react positively to diversity training and that it appears to
be quite effective at improving the way trainees think about diversity, although it affects
behavior to a lesser degree. Overall, diversity training worked best when accompanied by other
diversity management approaches that focused on both diversity skill development and
awareness and when continuously implemented over time (instead of just a one-time training
exercise). Many have found that the most effective programs engage people in working toward
diversity goals, increase contact among various demographic groups, and draw on peoples desire
to help one another.
On the other hand, it appears as if many are not sold on the effectiveness of diversity training.
For example, some note that there is a large obstacle to overcome: We are wired to make quick
interpretations and automatic judgments. According to esteemed behavioral economist Daniel
Kahneman, Trying to outsmart bias at the individual level is a bit of a fools errand, even with
training. We are fundamentally overconfident... so we make quick interpretations and automatic
judgments. Some diversity programs have failed because they too often attempt t.

Read above Case Study and answer below questions:
Assuming that you are a Freelance Project and Procurement expert, you have been approached
by Chandran for a fee to help him deal with his current predicaments. Help him to find his way
out to salvage the project that is slowly slipping from his control with the deadline fast
approaching.
TASKS:
Respond in writing by addressing the following in the report:
(a) His position as a contractor and what is expected from the client.
(b) A clear analysis of his case within the project contractual framework.
(c) Based on the above, make recommendations on the way forward and justify your
recommendations. The Cable Contract Chandran was confused as the project he had worked so
hard on, was turning out to be a quagmire. He searched for a way out of the predicament he was
in. A graduate from BMS College of Engineering, Bangalore (BMSCE), Chandran was a
qualified and licensed electrical contractor. He had recently secured a tender contract at a
premier government organization valued at Rs 2.7 lakh. The tender was for 'Replacement of
Faulty Cable to Feeder Pillar No 7 for providing power supply to the research blocks, hostels,
cabins etc., at National Technical Networks and Laboratories Limited (NTNL) Bhavan,
Bangalore - 16'. The contract was floated on a turnkey i basis by the Engineering and
Technological Maintenance Unit (ETMU) of NTNL on behalf of its Director for its Bangalore
Centre. ETMU was one of the many different departments within NTNL that routinely called for
tenders. The tender was dated October 25, 2001 and the work order was issued to Chandran on
the November 12, 2001. The time allowed to complete the project was 21 days including
weekends. No exceptions were permitted as the project was floated on an urgent and priority
basis. It was indeed a remarkable achievement for Chandran as this was his first assignment in an
organization of that repute. As a new comer to the profession he had earlier undertaken many
works that were sub-contracted ii to him by other contractors and for small organizations, but
had never on his own secured any contracts from bigger organizations like NTNL. The tendering
process at NTNL was the same as that of many government organizations. The tenders valued
below Rs 5 lakhs were non-transferable and of 'single cover' system. A bidder needed to submit
all the requested details in a single sealed cover that included the price quote. These tenders did
not require much experience from the bidders although the bidding contractors both civil and
electrical or any one of them, were required to possess government-issued licenses to execute the
works; and that depended on the nature of work for which the tender was called. Tenders valued
below Rs 25 lakhs required the bidders to possess sufficient expertise and experience in the
nature of works awarded. They were again a 'single cover' system but in that single sealed cover,
the bidders were required to submit two inner seal.

Apple iTunes and Amazon have far larger databases of subscribers and their preferences. Google
is actively pursuing long-form content creators for its video channel program. There is no cost to
Google users because the service is ad supporred. So another possible ending for the Netfix

There has been only one tech company in history that was successful with content production for
movies or television, and that is Pixar, which pioneered computer-generated animated feature-

the company refuses to release this data. Nielsen has begun a rating service for Netflix shows.
This service is paid for by the content producers who will base their charges in part on how many
Netflix subscribers stream their shows. While Netflix stands out as a powerful Internet brand

Question 1 Scenario Primary Data Analytics on Social Media Advertis.pdf
Question 1: Scenario Primary Data Analytics on Social Media Advertisement The means of
communication have changed in the advent of technology. Print media has matured as there have
been many alternatives supported by technology in digital marketing. Recently many businesses
have started to use lesser print media and relied on social media platforms to advertise and reach
out to consumers and the community. The objective of this assignment is to sample certain
demographics of business (within your community), to determine the preference of social media
toward advertising effectiveness from the perspective of consumers or users.

from a user or consumers perspective. Prepare questionnaire (approximate 10 questions) that
contain few demographic profile of the users, demographic profile of business and few
perception questions on the use, effectiveness, and preferences of social media advertising.
1b) What is your sampling method? Justify it. Then proceed to collect data (collect
approximately at least 30 respondents).
1c) Analyze the output of your output. You should use relevant graphical visualizations to
describe each of the questionnaire outcomes.
1d) Prepare an infographic to summarize the entire analysis. Write a short management
summary.

Q1. Entity-Relationship ModelingThe government of the province is .pdf
Q1. Entity-Relationship Modeling
The government of the province is implementing a program that manages vaccine distribution,
monitors
the pediatric and adult immunization levels and issues alerts when an emerging epidemic treat is
detected.
The program is managed by the Ministry of Health (MH). MH is building a dedicated an
information system
that can handle immunization records as well as vaccine distribution, vaccinee registration and
booking for
the immunizations that are covered under the provincial health insurance plan.
MH hired your team to build their new information system. Your team must design and
implement a new
relational database that meets the MHs informational requirements and supports the functionality
outlined
below.
Immunization providers that administer vaccines covered by the provincial health insurance plan
receive
the vaccines they will administer from the ministry. The MH must maintain accurate inventory
records to
keep track of the vaccines it procures from manufacturers and then distributes to providers. For
each lot of
vaccine, in addition to the type of vaccine in the lot, quantity of doses and expiration date, the
MH also
needs to record the supplier of the lot, along with information about them such as company name
and
address. For each manufacturer, the MH wants to also store the contact information of at least
one
manufacturer employee, their name, position, phone number and email, in case the lot has quality
issues
that need to be followed up on.
The MH also needs to store information about each vaccine provider (hospitals, pharmacies,
private clinics,
university health centres, walk-in centres, etc.), and the supplies they received. The MH assigns
one of its
employees to serves as the point of contact for each provider. The fulfillment of a vaccine
shipment to a
provider is personally overseen by that providers MH point of contact. A point of contact can
serve multiple
providers.
For each provider, the MH wants to record their name, address, along with contact information
for a person
from that organization (i.e., the persons name, position with the organization, phone number and
email) who it can keep informed about the dispatch of new vaccine shipments and other relevant
information.
Each shipment that the MH sends to a provider may include several different types of vaccines.
For each
shipment, MH needs to store, and be able to make available, the date of the shipment as well as
how many
doses of which type of vaccine were delivered and what vaccine lots the doses of each vaccine
type where
from.
In order to support an online vaccination booking system and serve as an immunization registry,
the MHs
system also needs to help collect information about each vaccination performed by a provider,
including
how many doses the person received, as some vaccines are multi-dose, and when the person
received their
first, and subsequent shots (for multi-dose vaccines). The MH must record, and be able to make
available,.

Programming For Big Data [ Submission DvcScheduleV2.cpp and StaticA.pdf
Programming For Big Data [ Submission: DvcScheduleV2.cpp and StaticArray.h and/or
DynamicArray.h ]
Assignment 5's runtime was too slow -- a couple of minutes or so. It's because of the duplicate-
checking, with over 4 billion compares.
Rewrite the duplicate-checking logic from Assignment 5, using a technique from "Techniques
For Big Data, Reading" to do fewer compares (check the term first then section number for the
duplicate check), and come up with the exact same results as Assignment 5.
You may use your StaticArray.h from Assignment 3 and/or your DynamicArray.h from
assignments 4, but you may not use any STL containers. Submit the H file(s) you use in your
solution, even if there are no changes since your previous work. Your project will be compiled
for grading using the default stack memory size of 1MB.
Since this version is supposed to be fast, there is no longer a need for a progress bar. Include one
if you wish (you may see the run time dramatically changed), or you may leave it out -- your
choice. But if you do have a progress bar, do remember to "flush"...

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
