Turing machines are a simple mathematical model of computation that was introduced by Alan Turing in 1936. A Turing machine consists of a finite set of states, an infinite tape divided into cells, and a head that can read and write symbols on the tape. It operates based on a transition function that changes the state and head position based on the current state and symbol. Turing machines can be used as language acceptors by accepting inputs that cause them to halt in an accepting state, or as transducers by treating the initial tape as input and final tape as output. Variations include multi-tape, non-deterministic, multi-head, and multi-dimensional Turing machines. Turing machines are useful for determining decid

Turing Machine (TM) is a mathematical model which consists of an infinite length tape divided into cells on which input is given. It consists of a head which reads the input tape. A state register stores the state of the Turing machine. After reading an input symbol, it is replaced with another symbol, its internal state is changed, and it moves from one cell to the right or left. If the TM reaches the final state, the input string is accepted, otherwise rejected.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

3. DEFINITION
A Turing machine (TM) is a finite-state machine with an infinite tape
and a tape head that can read or write one tape cell and move left or
right.
It normally accepts the input string, or completes its computation, by
entering a final or accepting state.
Tape is use for input and working storage.
4. Representation of Turing Machine
•
Turing Machine is represented by-
• M=(Q,Σ, Γ,δ,q0,B,F) ,
• Where
• Q is the finite state of states
• Σ a set of τ not including B, is the set of input symbols,
• τ is the finite state of allowable tape symbols,
• δ is the next move function, a mapping from Q × Γ to
• Q × Γ ×{L,R}
• Q0 in Q is the start state,
• B a symbol of Γ is the blank,
• F is the set of final states.
6. Transition function
One move (denoted by |---) in a TM does the following:
δ(q , X) = (p ,Y ,R/L)
• q is the current state
• X is the current tape symbol pointed by tape head
• State changes from q to p
7. Turing machine as language acceptors
A Turing machine halts when it no longer has available moves.
If it halts in a final state, it accepts its input, otherwise it rejects its
input.
For language accepted by M ,we define
L(M)={ w ε ∑+
: q0w |– x1qfx2 for some qf ε F , x1 ,x2ε Γ *
}
8. Turing machine as transducers
• To use a Turing machine as a transducer, treat the entire nonblank
portion of the initial tape as input
• Treat the entire nonblank portion of the tape when the machine halts
as output.
A Turing machine defines a function y = f (x) for strings x, y ε ∑*
if
q0x |*– qf y
• A function index is “Turing computable” if there exists a Turing
machine that can perform the above task.
9. ID of a TMID of a TM
• Instantaneous Description or ID :
X1 X2…Xi-1 q Xi Xi+1 …Xn
Means:
q is the current state
Tape head is pointing to Xi
X1X2…Xi-1XiXi+1… Xn are the current tape symbols
δ (q , Xi ) = (p ,Y , R ) is same as:δ (q , Xi ) = (p ,Y , R ) is same as:
X1 X2…Xi-1 q Xi Xi+1 …Xn|---- X1 X2…Xi-1 YY pp Xi+1…Xn
δδ (q Xi) = (p Y L) same as:(q Xi) = (p Y L) same as:
X1 X2…Xi-1 q Xi Xi+1 …Xn|---- X1 X2…ppXi-1YY Xi+1 …Xn
11. MULTITAPE TURING MACHINES
A Turing Machine with several tapes
Every Tape’s have their Controlled own R/W Head
For N- tape TM M=(Q,Σ, Γ,δ,q0,B,F)
• we define δ : Q X ΓN
Q X ΓN
X { L , R} N
12. NON DETERMINISTIC TURINGNON DETERMINISTIC TURING
MACHINESMACHINES
It is similar to DTM except that for any input symbol and current
state it has a number of choices
A string is accepted by a NDTM if there is a sequence of moves that
leads to a final state
The transaction function δ : Q X Γ 2 QXΓ X{L,R}
13. MULTIHEAD TURING MACHINEMULTIHEAD TURING MACHINE
Multihead TM has a number of heads instead of one.
Each head indepently read/ write symbols and move left / right or
keep stationery.
14. OFF- LINE TURING MACHINEOFF- LINE TURING MACHINE
An Offline Turing Machine has two tapes
1. One tape is read-only and contains the input
2. The other is read-write and is initially blank.
15. MULTIDIMENSIONAL TURINGMULTIDIMENSIONAL TURING
MACHINEMACHINE
A Multidimensional TM has a multidimensional tape.
• For example, a two-dimensional Turing machine would read and
write on an infinite plane divided into squares, like a checkerboard.
For a two- Dimensional Turing Machine transaction function define
as:
• δ : Q X Γ Q X Γ X { L , R,U,D}
16. Applications of TM
• Check Decidability If TM cannot solve a problem in countable time
then there could not be any algorithm which could solve that
problem (That is the problem is undecidable).For a decision problem
if its TM halt in countable time for all finite length inputs then we can
say that the problem could be solved by an algorithm in countable
time.
• Classify Problem TM helps to classify decidable problems into classes
of Polynomial Hierarchy. Suppose we found that the problem is
decidable. Then out target become how efficiently we can solve it.
The efficiency been calculated in number of steps, extra space used ,
length of the code/size of the FSM.
• Design and Implement Algorithm for Practical Machines TM helps to
propagate idea of algorithm in other practical machines. After the
successful check of 1,2 criteria we can use our practical
devices/computers to design and implement algorithm.
