Since the industrial revolution, modern technologies have progressively provided man with more comfort, better health, and higher quality of life. The evidence is clear. Man’s life expectancy has more than doubled during the past few centuries. But new challenges have also risen, from cancer and brain diseases to movement disabilities due to aging populations, inactive lifestyles, and polluted environments. These challenges also come with the expectation of higher performance and more efficiency in operations more closely intertwined with man.
In this talk, we will consider the above aspects within the context of robotic rehabilitation and artificial intelligence. In particular, I hope to present some of our soft computing strategies and how the uncertainties and complexities of the rehabilitation process necessitate them.
Machine learning can be used to predict whether a user will purchase a book on an online book store. Features about the user, book, and user-book interactions can be generated and used in a machine learning model. A multi-stage modeling approach could first predict if a user will view a book, and then predict if they will purchase it, with the predicted view probability as an additional feature. Decision trees, logistic regression, or other classification algorithms could be used to build models at each stage. This approach aims to leverage user data to provide personalized book recommendations.

Artificial Intelligence for Automated Decision Support ProjectValerii Klymchuk
Artificial intelligence can be used to develop automated decision support systems. There are different types of AI systems like expert systems, knowledge-based systems, and neural networks that can learn from data and apply rules to make decisions. One example is IBM's Watson, which uses natural language processing and evidence-based learning to provide personalized medical recommendations. Automated decision systems are rule-based and can make repetitive operational decisions in real-time, like pricing and loan approvals, freeing up human workers for more complex tasks. The key components of these systems are knowledge acquisition from experts, knowledge representation in a structured format like rules, and inference engines that apply the rules to draw new conclusions.
This document provides an overview of artificial intelligence techniques and their applications in power systems. It discusses expert systems, artificial neural networks, and fuzzy logic systems as the three major AI techniques used. It describes how each technique works and its advantages/disadvantages. The document also gives examples of how these techniques can be applied in transmission lines, power system protection, and other areas like operations, planning, control, and automation of power systems. The conclusion states that while AI shows promise for improving power system efficiency and reliability, more research is still needed to fully realize its benefits.

Road construction is not as easy as it seems to be, it includes various steps and it starts with its designing and
structure including the traffic volume consideration. Then base layer is done by bulldozers and levelers and after
base surface coating has to be done. For giving road a smooth surface with flexibility, Asphalt concrete is used.
Asphalt requires an aggregate sub base material layer, and then a base layer to be put into first place. Asphalt road
construction is formulated to support the heavy traffic load and climatic conditions. It is 100% recyclable and
saving non renewable natural resources.
With the advancement of technology, Asphalt technology gives assurance about the good drainage system and with
skid resistance it can be used where safety is necessary such as outsidethe schools.
The largest use of Asphalt is for making asphalt concrete for road surfaces. It is widely used in airports around the
world due to the sturdiness and ability to be repaired quickly, it is widely used for runways dedicated to aircraft
landing and taking off. Asphalt is normally stored and transported at 150’C or 300’F temperature

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

17. How do some control engineers treat
COMPLEX Systems?
1. Decomposition – Assumption 1
It is easier to work with less complex systems.
2. Slowly varying variables -Assumption 2
It is easier to replace variables by constants.
3. Linearization – Assumption 3
It is always easier to work with linear systems.
4. Controllable & Observable System -- Assumption 4
It is necessary to do the design.
5. Delays are assumed to be non-existent x(t-t) =x(t) -- Assumption 5

21. In other words, with a realistic view,
• Seldom: Both the governing dynamical laws and parameters
are known
– Such as in robot modeling by following the natural laws of physics and where
the parameters can be measured. (White Box)
But even so, they could be mathematically (for analytical work) and numerically
(for real-time work) too complicated.
• Often, either:
– The governing dynamical laws are known, but the parameters are not
(Such as in robot modeling where friction must be estimated. (tools of
identification) (Grey)
– There is no/only partial knowledge on the governing laws and
parameters (Such as in weather forecasting, financial markets, and when
involving human in the loop. (Data-driven techniques, Darker Grey to Black)
But what if the desired is not known?
22. But what if the desired is not known or
is ill-defined?
• This is an uprising problem.
• In human centered systems, the
desired output is itself uncertain.
• For illustration, here we consider
the case study of rehabilitative
robotics.

46. Bionic Hands:
• Intuitive motion should be fast and
accurate.
• It begins with a proper signal along
with intelligent processing.
• Current signaling technologies are
1. EEG: Highly inaccurate and noisy, what about
loose probes
2. Probe embedded EEG: Too invasive
3. EMG: More accurate, but
– Amputated hands lose range of movement and
so less muscle activity
– Loose probes still persist.
4. Embedded magnets: Kineticomyography
– No probes, accurate and fast (+++),
– Needs surgery for implantation (-)
