DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

56. 1. Identifying/formulating the Research Problem:
Defining the topic, research questions, and objectives.
Research problems may involve natural states or variable relationships.
Researchers select a specific area of interest.
Problems are refined for clarity and feasibility.
Discuss the problem with colleagues or experts.
Seek guidance from a mentor.
Administrative agencies in organizations identify and discuss problems with
researchers.
Study existing literature to understand the problem and identify data.
Refine the problem for clarity and objectivity, defining relevant terms as
needed.

related to the research problem, in indexed journals, Academic journals,
conference proceedings, government reports, books etc.
3. Development of working hypotheses or Research Questions:
Developing clear, testable statements or inquiries to guide the research.
Discuss with colleagues and experts to understand the problem's origins
and goals.
Examination of available data for trends and clues.
Review similar studies for insights.
Conduct field interviews for practical understanding.
58. 4. Preparing the research design/ Designing the Study:
The research design preparation typically involves considering:
How to gather information
The researcher's and staff's capabilities
Organization of information-gathering methods and rationale behind
selection
Time constraints
Financial resources available
59. 5. Determining Sample Design/ Collecting Data:
Gathering relevant data through observation, experimentation, surveys,
interviews, or other methods.
Inquiry in any field considers all items, termed as the 'population,' but often
only a sample is feasible due to time, cost, and practical constraints.
The researcher plans how to pick a sample from a population, either with
known inclusion probabilities (probability samples) or unknown probabilities
(non-probability samples), using techniques like random or convenience
sampling.
Important Sample Designs
60. 5.1 Deliberate sampling:
Purposeful selection of units to form a representative sample.
Convenience Sampling: Selection based on accessibility, potentially
leading to bias.(non-probability)
Judgement Sampling: Selection guided by the researcher's judgment,
often used in qualitative research for hypothesis development.
5.2 Simple random sampling:
Random sampling is like a fair game where every item has the same
chance to be picked.
Whether you're choosing 300 items from 15,000 or even from an
infinite group, each item has an equal shot at being selected.
Methods like a lottery or random number tables help ensure fairness.
Each pick is independent and equally likely, just like flipping a fair
coin.
61. 5.3. Systematic sampling:
Systematic sampling involves selecting every nth item from a list or
population.
A random starting point is chosen within the list.
Selecting a random starting point and then selecting every nth element until
the desired sample size is obtained.
5.4. Stratified sampling:
Used for diverse populations to get a fair sample.
Divides population into groups (strata) based on characteristics.
Samples chosen from each stratum.
If samples are randomly selected from each group, it’s called stratified
random sampling.
62. 5.5 Area sampling
Like cluster sampling for large areas.
Divides area into clusters.
Randomly selects clusters, includes all units within.
Helpful without population list.
Enhances efficiency in field interviews.
5.6. Multi-stage Sampling:
Builds on cluster sampling for large inquiries.
Selects primary units like states, districts, towns, and families.
If random sampling is used at each stage, it's called multi-stage random sampling.
5.7. Sequential Sampling:
Sample size dynamically determined based on survey progress.
Often used in statistical quality control acceptance sampling plans.
63. 6. Collecting Data:
Real-life problems often have inadequate data, requiring appropriate collection.
Various methods differ in cost, time, and resources available to the researcher.
Primary Data Can be obtained via experiment or survey.
Observation: Investigator observes without interviewing, limited and costly.
Personal Interview: Rigid procedure with pre-set questions, depends on
interviewer's skill.
Telephone Interviews: Contacting respondents by phone, useful for time-
sensitive surveys.
Mailing Questionnaires: Questionnaires sent by mail, extensively used but
requires careful preparation.
Schedules: Enumerators fill schedules based on respondent replies, reliability
depends on enumerator competence with occasional field checks.
64. 7. Execution of the project:
Vital for reliable data.
Requires systematic approach and timeline adherence.
Structured questionnaires need coding.
Proper selection and training for interviewers.
Regular monitoring ensures diligence.
Statistical control maintains accuracy.
Addressing non-cooperation may involve sub-sampling and expert help.
65. 8. Analysis of data:
Involves several operations: establishing categories, coding, tabulation, and
drawing statistical inferences.
Raw data condensed into manageable groups and tables.
Categories classified for usability, then coded for tabulation.
Editing improves data quality for coding.
Tabulation organizes data into tables, often done by computers to save time.
Involves computing percentages, coefficients, etc., using statistical formulas.
Tests of significance determine if relationships or differences support
hypotheses.
Statistical tests establish if observed differences are real or due to chance.
For example, analysis of variance helps compare results from different seed
varieties.
Various statistical measures assist researchers in analyzing collected data.
66. 9. Hypothesis-testing:
Analyze data to test hypotheses.
Use statistical tests like Chi-square, t-test(µ), or F-test(σ).
Results: either accept or reject hypotheses.
If no initial hypotheses, use data-based generalizations for future research.
10. Generalizations and interpretation:
Confirming a hypothesis leads to theories.
Research finds general conclusions.
Findings can be explained using existing theories interpretation.
This leads to new questions and more research.
67. 11. Preparation of the report or the thesis:
The researcher must prepare a carefully written report. Attention to detail is
crucial in writing the report. Key considerations include:
1. The report layout consists of three parts: Preliminary pages, Main text, End
matter
Preliminary pages include:
Title and date
Acknowledgments and foreword
Table of contents
List of tables and graphs
68. The main text comprises:
a) Introduction: Objective, methodology, scope, and limitations.

10. Challenges with conceptualization and data collection processes
79. Research problem: Difficulty faced by a researcher in a theoretical or practical
situation requiring a solution.
Conditions for existence:
1. 'I' exists as an individual, group, or organization within environment 'N'
defined by uncontrolled variables, Yj.
2. At least two courses of action, C1 and C2, are available.
3. There are at least two possible outcomes, O1 and O2, with one being
preferable.
4. Courses of action offer differing probabilities of achieving the objective:
P(Oj | I, Cj, N) with P(O1 | I, C1, N) ≠ P(O1 | I, C2, N).
80. "I" faces a research problem when uncertain about the best course of action
among multiple options, all with differing efficiencies for desired objectives.
The components of a research problem
Individual or group experiencing difficulty.
Existence of objective(s) to achieve.
Availability of alternative means to attain objectives.
Uncertainty in selecting alternatives.
Relevance of difficulty to a specific environment(s)
A research problem is about finding the best way to achieve a goal, considering
factors like environmental changes and different options available.
82. Selecting a research problem is important, guided help is useful but the problem
should come from the researcher's own ideas, considering their expertise and
interests
Avoid overdone or controversial topics.
Steer clear of problems that are too narrow or vague.
Choose a familiar and feasible subject.
Seek guidance from experts and review current literature.
Consider the importance of the subject, researcher's qualifications, costs, and
time.
Conduct a preliminary study before final problem selection.
84. Clear definition of a research problem is essential.
It helps in distinguishing relevant data from irrelevant.
Properly defined problems guide data collection, study characteristics, and
exploration of relations.
Defining the problem aids in planning research strategy and answering related
questions.
Formulating the problem is crucial for designing the research and executing
subsequent steps effectively.
86. Defining a research problem involves stating its bounds, understanding its
nature, reviewing literature, discussing ideas, and refining it, requiring
careful consideration to avoid confusion.
1. Statement of the problem in a general way:
Begin by stating the problem broadly, considering practical or
intellectual interests.
Understand the subject matter thoroughly, possibly through field
observation or pilot surveys.

90. Consider these additional points while defining the research problem.
Define technical terms clearly.
State any assumptions.
Provide the investigation's value.
Consider time-period and data sources.
Specify the scope of the investigation.
92. Start with a broad question: "Why is productivity higher in Japan than in
India?"
Ambiguities include: type of productivity, related industries, and time
period.
Narrow down the question to focus on specific factors: "What factors
contributed to higher labor productivity in Japan's manufacturing industries
during 1971-1980 compared to India?"
Refine the question further for clarity and specificity: "To what extent did
labor productivity exceed India's in 15 selected manufacturing industries
during 1971-1980?
What factors caused productivity differences between the two countries?"
93. With this sort of formulation,
Clarify terms like “labor productivity."
Confirm data availability for selected industries and time-period.
Substitute industries if necessary.
Assess the suitability of the time period.
Consider all factors before defining the research problem.
Defining a research problem involves starting broadly, resolving uncertainties,
and refining for clarity, leading to clear hypotheses and solutions.
