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.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
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%.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM

To be presented at the National Conference On 4th
February, 2013 On “Trend and opportunities in Management
Discipline”
Organized by,
Anand Institute of Management, Anand
Affiliated to Gujarat Technological University
Abstract
In today’s competitive world its necessary any industry run their operation in smooth manner and deliver its
customer best products at minimum time, and to fulfil this purpose maintenance management is key area
where every industry work. Now a day’s continuous or mass production system is used in industry in which
if any one of the equipment is fail remaining all work schedule are disturbed, in this type of scenario
maintenance management important increase automatically. Maintenance management is not a new concept
but oldest in nature which passes so many phases of it journey. This paper derives various trend or concept
used in maintenance management to maintain equipment in running condition and also achieving optimum
level of productivity.
Maintenance Management
The old concept of Maintenance was “Maintenance is about preserving physical asset”. However, the new
concept is that “Maintenance is about preserving the functions of assets”. Maintenance can be define as “It is
a routine or a recurring process of keeping a particular machine or asset in its normal operating condition, so
that it can deliver its expected performance or service without causing any loss of time on account of
accidental damage or breakdown.”
Main function is to keep the equipment in working condition by replacing or repairing some of the
component of the machine and increased availability of production system, with increased safety and
optimized cost.
Maintenance management involve managing function of maintenance. Maintaining equipment in the field
has been a challenging task since the beginning of industrial revolution. Since then, a significant of progress
has been made to maintain equipment effectively in the field. As the engineering equipment becomes
2. sophisticated and expensive to produce and maintain, maintenance management has face even more
challenging situations to maintain effectively such equipments in industrial environment.
Maintenance Management is important aspect because,
1. It lowers down production unit cost
2. It minimize downtime
3. It improves total availability of system.
4. It extended useful life of equipment
5. It increases safety of personals.
6. It helps in reducing overtime and out-sourcing.
7. It provides better process stability.
8. It reduce maintenance part inventory.

Trend in Maintenance Management
Actually, Maintenance is an age old function, which developed and progressed, knowingly or unknowingly,
along with the operation of the equipment/ machines. In early ages, maintenance was not a separate identity
but the job of maintenance was considered as part and parcel of operator’s job. This was possible because of
simplicity and openness of the machines. Even carvings on the Egyptian tomb “Ra-Em-Ka-“(about 2600 –
1700 BC) used lubrication to transport a stone mountain. Here some concept of Maintenance management
given as per there generation.
Before 1950,
1. Breakdown Maintenance Management System
Breakdown Maintenance concept/system is oldest concept in Maintenance management. In this not do
anything as long as everything is going well and maintenance repair is done after failure has already
occurred. The equipment allowed running undisturbed till it fails. This maintenance concept also called as
Reactive Maintenance Concept or Unplanned Maintenance or Operate to failure concept.
Breakdown maintenance can only be suitable for small scale industries where numbers of equipments are
few and sudden failure of equipment will not cause several financial losses in term of delivery commitment.
This system look to be simple and less expensive, but is not really so. It does not provide any guarantee of
4. reliability to the smooth production running. In breakdown maintenance downtime of equipment is high
after breakdown.
Between 1950 to 1960,
2. Preventive Maintenance Management System
Some group of Japanese engineers started a new concept/system in maintenance that consisted on following
the manufactures recommendation about the care that should be taken in the operation and maintenance of
machine and devices. That new concept was called Preventive Maintenance or Schedule Maintenance
Concept. This Maintenance program is scheduled in consultation with the production/operation department
so that relevant equipment is made available for maintenance work and utilizes idle time of equipment. In
this maintenance action such as inspection, lubrication, cleaning, adjustment and replacement are undertaken
at fixed interval of number of hours or kilometres. Although it reduces downtime it was an expensive
alternative. The reason many parts were replaced on a time basis, while they could have lasted longer. Also
many unnecessary man-hours were put into it and in not few cases excess lubrication caused more damage
than good.
Between 1960 to 1970,
3. Predictive Maintenance Management System
With time change new concept/system established which determined a more professional approach. This
assign of higher responsibility to all the people related to maintenance consisted of series of considerations
about the reliability and design of equipment and plant itself. When equipment/system is taken down for
maintenance, changing one or few warn out component opportunity can be utilized for maintenance,
changing other wearing out component even though they have not failed. This would probably be
economical in the long run. It is very beneficial for non-monitored component which are inaccessible for
inspection. This maintenance concept also called as Productive Maintenance Concept or Opportunity
Maintenance Concept or Reliability Maintenance Management Concept.
5. 4. Condition based Maintenance Management System
Condition monitoring detects and diagnoses faults and it helps in planned maintenance based on equipment
condition. This condition based on maintenance strategy is preferred for critical system and for such system
breakdown maintenance is to be avoided. A number of condition based maintenance techniques such as
vibration, temperature, oil analysis, etc. Have been developed, which guide the users in planned
maintenance.
Between 1970 to 1985,
5. Total Productive Maintenance Management System
The globalization of the market created new stronger needs for excellence in all activities. The world class
standards in terms of equipment maintenance were understood, a dynamic system was created. Total
Productive Maintenance is a continuous improvement concept that has proven to be effective, first in Japan
and now back in America (where first created). It is about the involvement and participation of each and
every one of the members in the organizations toward optimizing the outcome of each piece of equipment.
This is a completely new philosophy is different approach that will keep updated by itself. It implies a
continuous improvement in all aspect and is also called Total Participation Maintenance.
The purpose is to transform the attitude of all the members of the industrial community, all kinds and levels
of workers, operators, supervisors, engineers, administrators are included in this major responsibility. TPM
implementation is a goal that all company members share. It also generates benefits for all. Through this
effort, all are responsible for the up keeping of the equipment. It becomes more productive, safer and easier
to operate and even looks nicer. The participation of people, who are not familiar with the equipment and its
operation, enriches the result because their observations are in many cases more objective than those of the
people who live with equipment in a daily basis.
6. Routine Maintenance Management System
It is the Simplest form of part maintenance but very essential which Carrying out minor maintenance job
such as cleaning, lubrication, inspection, minor adjustment of pressure, flow, tightness, etc. or inspection of
bearing, belts, coupling, joints, foundations, bolts, earthings, etc. at regular intervals. Small/Critical effects
using such inspection are rectified immediately. It is not need base, all equipment are inspected. It may
consider small portion of preventive maintenance. It needs very little investment in terms of time and
money. The duration routine maintenance is generally so small that it does not affect the output of machine
appreciably. However, the cost of not doing routine maintenance may be very high as a small develop in
big and catastrophic failure.
6. After 1985,
7. Computerized Maintenance Management System (CMMS)
It is also known as Enterprise Asset Management and Computerized Maintenance Management Information
System (CMMIS). A CMMS software package maintains a computer database of information about an
organization’s maintenance operations. This information is intended to help maintenance worker do their
jobs more effectively and to help management make informed decisions. CMMS data may also be used to
verify regulatory compliance. CMMS package may be used by any organization that must perform
maintenance on equipment, assets and property. CMMS packages can produce status reports and documents
giving details or summaries of maintenance activities. The more sophisticated the package, the more
analysis facilities are available. Many CMMS packages can be either web based meaning they are hosted by
the company selling the product on an outside server or LAN based meaning that the company buying the
software hosts the product on their own server.
Selection criteria for selection of good Maintenance Management System
Presently many maintenance management systems are in use in industries and selection has to be made
depending the need, complexity and reliability needed and also considering techno-economics. Criteria must
consider are-
1) Work Procedures (Maintenance and Operation etc.)
2) Problems, Defect and Fault Reports
3) Work Schedules, Job Orders etc.
4) Work History
5) Assets
6) Inventory
7) Finance, etc.
7. Conclusion
All above discussion has briefly focused on the various trend of maintenance management. In maintenance
new trend come out but old trend not closed or go out because all maintenance management system has their
own applicability. Maintenance management plays larger role in years to follow as industrial growth
increase worldwide and increase competition and automation of plants. As industrial progress increases the
downtime cost for system is increase and to meet these challenges, maintenance person has to use latest
technology and develop management skill to perform effective role in industrial profit.
