Fuzzy logic is a form of multivalued logic that deals with approximate reasoning rather than binary logic. It allows intermediate values between conventional evaluations like true/false, yes/no, or 0/1. Fuzzy logic variables can have membership values between 0 and 1 and are not constrained to two truth values. It has been applied to fields like control theory and artificial intelligence. Fuzzy logic uses IF-THEN rules to represent knowledge with linguistic terms rather than precise quantitative values and allows for gradual transitions between categories.

How can you deal with Fuzzy Logic. Fuzzy logic is a form of many-valued logic; it deals with reasoning that is approximate rather than fixed and exact. In contrast with traditional logic theory, where binary sets have two-valued logic: true or false, fuzzy logic variables may have a truth value that ranges in degree
between 0 and 1
Determination of the preceptor is one of academic obligations. Undesirable things always happen in getting optimal decisions in which faculty are assigned not the most appropriate to the topic of thesis. This matter can affect the result and the quality of the thesis. The research process uses the input variable of lecturers criteria. The data will be processed by using the method of fuzzy logic to obtain the output consists of preceptors and examiners. In this case, the students do not have to worry about the competence of the lectures since the lecturers who have been given to them are fully filtered.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

2. Introduction
Form of multivalued logic
Deals reasoning that is approximate rather
than precise
the fuzzy logic variables may have
a membership value of not only 0 or 1 –
that is, the degree of truth of
a statement can range between 0 and 1 and
is not constrained to the two truth values of
classic propositional logic
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 2
3. Introduction
Fuzzy logic has been applied to many fields,
from control theory to artificial intelligence
it still remains controversial among
most statisticians, who prefer Bayesian
logic, and
some control engineers, who prefer
traditional two-valued logic.
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 3
4. Degrees of truth
let a 100 ml glass contain 30 ml of water.
Then we may consider two concepts: Empty
and Full.
The meaning of each of them can be
represented by a certain fuzzy set.
Then one might define the glass as being
0.7 empty and 0.3 full.
The concept of emptiness would
be subjective and thus would depend on
the observer or designer.
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 4
5. An image that describe fuzzy
logic
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 5
6. An image that describe fuzzy
logic
A point on that scale has three "truth
values" — one for each of the three
functions.
Since the red arrow points to zero, this
temperature may be interpreted as "not
hot".
The orange arrow (pointing at 0.2) may
describe it as "slightly warm" and
the blue arrow (pointing at 0.8) "fairly cold".
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 6
7. Fuzzy Rules
fuzzy logic usually uses IF-THEN rules
Rules are usually expressed in the form:
IF variable IS property THEN action
For example, a simple temperature
regulator that uses a fan might look like
this:
IF temperature IS very cold THEN stop fan
IF temperature IS cold THEN turn down fan
IF temperature IS normal THEN maintain level
IF temperature IS hot THEN speed up fan
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 7
8. Fuzzy Rules
There is no "ELSE" – all of the rules are
evaluated, because the temperature might
be "cold" and "normal" at the same time to
different degrees.
The AND, OR, and
NOT operators of boolean logic exist in
fuzzy logic, usually defined as the minimum,
maximum, and complement
when they are defined this way, they are
called the Zadeh operators
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 8
9. Zadeh Operators
NOT x = (1 - truth(x))
x AND y = minimum(truth(x), truth(y))
x OR y = maximum(truth(x), truth(y))
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 9
10. Hedges
There are also other operators, more
linguistic in nature, called hedges that can
be applied.
These are generally adverbs such as "very",
or "somewhat"
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 10
11. Fuzzy Logic Applications
Air conditioning
Washing Machines (LG is the pioneer)
Mono-rails (first used in Tokyo)
Digital image processing (specially in medical imaging)
Elevators (in case of power failure)
Rice cookers
Video game engines (disperse intelligence in prince of
Persia)
Special effects (swarm intelligence in Batman Begins,
Terminator Salvation, The Lord of the Rings)
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 11
12. Objections against Fuzzy Logic
The concept of "coldness" cannot be
expressed in an equation, because although
temperature is a quantity, "coldness" is not
people have an idea of what "cold" is, and
agree that there is no sharp cutoff between
"cold" and "not cold"
where something is "cold" at N degrees but
"not cold" at N+1 degrees — a concept
classical logic cannot easily handle
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 12
13. Objections against Fuzzy Logic
The result has no set answer so it is
believed to be a 'fuzzy' answer.
Fuzzy logic simply provides a mathematical
model of the vagueness which is manifested
in the above example.
Rushdi Shams, Lecturer, Dept of CSE, KUET, Bangladesh 13
14. A new way to represent
probabilistic logic?
fuzzy set theory uses the concept of fuzzy
set membership (i.e., how much a variable
is in a set)
probability theory uses the concept
of subjective probability (i.e., how
probable do I think that a variable is in a
set).
