Computer world has totally taking
over the whole world.
Even 3 months old is ready to use
computer, phones and all sorts even at their little age.
Energy and Power
Think about this circumstance:
It is August 15, 2030, a partly
sunny, hot day in Phoenix, AZ. The Jones, Ortiz, and Garcia families reside in
neighboring homes equipped with state-of-the-art sensing and control
capabilities. The families have deployed solar panels on their roofs, augmented
by a nearby wind farm with associated energy storage.
On this particular day, the
Garcias are on vacation, so their generated energy is deposited into the
community storage “bank” – and they receive a credit to be used at a later
time. By contrast, the Ortizs are home, and having invited many out-of-town
guests for a big family reunion, they may draw extra energy from the local
storage bank, debiting the credits they have built up in the past.
The Jones’, meantime, spend the morning at
home but are away during the afternoon. While they’re home, their air
conditioning system overcools the structure specifically when the sun peaks out
from behind the scattered clouds. But when they’re away, the home computer
system allows the household temperature to rise to a level that minimizes
energy usage, all the while ensuring no harm to the family cat or tropical
fish.
The computer also detects when
the family is about 30 minutes away, and it begins to cool the home at that
point, knowing it takes about 30 minutes to return the temperature to the
Jones’ preferred reading. At various times, the families’ home computers
negotiate price packages with the local neighborhood exchange, which in turn
negotiates price packages with the utility grid – donating or recovering excess
energy units.
Computer science is working to
enable this vision for a distributed, adaptive, and market-based infrastructure
for the generation, distribution, and consumption of electrical energy – or
what is commonly referred to as the “smart grid.” The smart grid will need to
go well beyond today’s infrastructure and will make extensive use of existing
information technology. Ultimately, the smart grid vision is to deliver
high-quality power to all subscribers simultaneously – no matter their demand.
Nationwide security
The intelligence community is faced with an increasing
deluge of data – including ground- and aerial-based reconnaissance information
(e.g., satellite imagery), intercepted communications (e.g., voice, email),
captured media (e.g., computer hard drives, videos, images), biometric data
(e.g., facial images, DNA, iris, fingerprint, gait recordings), and corporate
knowledge repositories (e.g., airline passenger manifests, credit card and bank
transactions, employee personnel records, even electronic medical records).
The challenge for
intelligence analysts is to find, combine, and detect patterns and trends in
the traces of important information lurking among these vast quantities of
available data – in order to recognize threats and to assess the capabilities and
vulnerabilities of those who wish to cause harm.
Computer science is making analysts more efficient by
reducing the volume of data that they must review through document filtering
and summarization. Technologies developed through computer science can eliminate
language barriers via automatic translation and multilingual search and can
support collaboration between analysts through information sharing tools.
And computer science can also help analysts be more vigilant
by automatically generating notifications when suspicious activities are
detected, updating the activity detector based on analyst feedback. Ultimately,
fundamental advances in computing stand to augment the power of human
intelligence analysts, enhancing our ability to detect and defeat specific
threats.
Healthiness and Care
Computer science is facilitating a much-needed
transformation in care delivery. The vision for health care in the 21st Century
will need a system that:
enables mining of huge volumes of patient data from multiple
sources, and effectively present the right pieces of information to the right
person at the right time to help yield the right decision – while safeguarding
the privacy and security of patients.
facilitates monitoring and assisting patients’ health,
activities, and behaviors in their homes, offices, and community centers – not
just in hospitals or care clinics.
creates an entirely new social infrastructure, one that
builds off of today’s “connected” world and incentivizes integration and
adoption of new technologies, a belief in wellness management (“prevention is
better than a cure”), and the role and persuasive effects of one’s social
network.
