Suppose the lifetime of a van has a uniform distribution over [3,10]. Mr Smith buys a new
van as soon as his old van either breaks down or reaches the age of 8 years. A new van costs
$20,000 and an additional cost of $1000 is incurred whenever a van breaks down. Assume
that a T years old car in working order has an expected resale value of 20,000[(1000T)/2].
What is Mr Smith\'s long-run average cost?
Solution
L= Lifetime of the van
L~ U(0,10)
I[A] is the indicator function which takes the value 1 if A is true and 0 otherwise.
Long run cost of Mr. Smith
= Cost incurred* I[ old van breaks down before reaching the age of 8 years] + Cost incurred * [
old van reaches the age of 8 years]
Thus Expected long run cost
= Cost Incurred* P[old van breaks down before reaching the age of 8 years]+ Cost incurred *
P[old van survived reaches the age of 8 years]
= $ 21000* P[ L < 8 ] + ${20000-1000*8/2}* P[ L > 8]
= $ 21000* (8-3)/(10-3) + $16000 * (10-8)/(10-3)
= $ 21000* 5/7 + $ 16000* 2/7
= $ 15000 + $ 4571.4
=$ 19571.4

Suppose the life of a particular brand of calculator battery is approximately normally distributed
with a mean of 75 hours and a standard deviation of 10 hours. What is the probability that a
single battery randomly selected from the population will have a life between 70 and 80 hours?
Solution
using a Z score we get Zup = (80-75)/10 = .5 and Zdown = (70-75)/10 = -.5 so
using a table we know that the probability of being between the mean and .5 standard deviations
from the mean is .1915 and doubling that for the other side gives us a probability of .383.

Suppose that you are designing a new video streaming service. You ha.pdf
Suppose that you are designing a new video streaming service. You have chosen the DASH
system (Dynamic Adaptive Streaming over HTTP), so you have created a method to store
different versions of the video encoded at different bitrates. This allows your end-user to select
the bitrate they want to see when they play the video. Explain how this system can be utilized to
overcome network related issues, especially if your service controls the video player application.
Describe the interaction that should occur as the client program encounters common network
issues like delay, jitter or packet loss.
Solution
MPEG-DASH builds on the already excellent adaptive streaming technologies deployed today.
The MP4 File Format (based on the ISO Base Media File Format) enables common encryption to
allow delivery of content to a wide range of devices with various DRM schemes. MPEG-DASH
also allows multiple language versions of the same content to be delivered thus enlarging target
audiences. Whether consuming traffic from a service provider’s own content offering, or using a
new over-the-top service, video consumption to IP-enabled devices is driving up traffic on
operators’ networks. Building out new capacity to cope with today’s demands and the predicted
growth over the coming years is prohibitively expensive, yet consumers continue to expect
higher quality IP video without a corresponding hike in broadband access charges.
MPEG-DASH will help to overcome some of the challenges of other adaptive streaming formats
and provides service providers with the confidence coming from embracing a truly global
standard.
What MPEG-DASH aims to do is simplify the delivery landscape and help realize the promise
of adaptive streaming.
MPEG-DASH enables the delivery of content to all devices. One of the major challenges facing
content and service providers is the fragmentation of devices. It is no longer enough to create a
single version of a video asset for presentation on the household TV. Multiple viewing devices
with differing screen sizes receive content over networks with capacities that vary over time; a
Smartphone on a 3G mobile network requires a completely different asset than the 50” HDTV in
the living room. MPEG-DASH reduces cost at every step of the chain from content preparation,
hosting, caching to final delivery. MPEG-DASH, as an http adaptive streaming technology,
promises to reduce complexity by allowing the receiving device to select which resolution and
bitrate stream to view, and the ability to change the choice over time as network conditions
demand. This will allow content providers to concentrate on generating a fixed number of
choices for each asset, greatly simplifying their workflow. It will also allow business models to
expand to cater for content even further down the “tail”. It will also allow delivery of content to
homes that were previously out of reach commercially..

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems
9
Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
