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.

The integration of cutting-edge technologies, including sensors, actuators, and data analysis, empowers this system to provide accurate monitoring and control of irrigation processes by leveraging real-time environmental conditions. The main objective of a smart irrigation system is to optimize water efficiency, minimize expenses, and foster the adoption of sustainable water management methods. This paper conducts a systematic risk assessment by exploring the key components/assets and their functionalities in the smart irrigation system. The crucial role of sensors in gathering data on soil moisture, weather patterns, and plant well-being is emphasized in this system. These sensors enable intelligent decision-making in irrigation scheduling and water distribution, leading to enhanced water efficiency and sustainable water management practices. Actuators enable automated control of irrigation devices, ensuring precise and targeted water delivery to plants. Additionally, the paper addresses the potential threat and vulnerabilities associated with smart irrigation systems. It discusses limitations of the system, such as power constraints and computational capabilities, and calculates the potential security risks. The paper suggests possible risk treatment methods for effective secure system operation. In conclusion, the paper emphasizes the significant benefits of implementing smart irrigation systems, including improved water conservation, increased crop yield, and reduced environmental impact. Additionally, based on the security analysis conducted, the paper recommends the implementation of countermeasures and security approaches to address vulnerabilities and ensure the integrity and reliability of the system. By incorporating these measures, smart irrigation technology can revolutionize water management practices in agriculture, promoting sustainability, resource efficiency, and safeguarding against potential security threats.
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.

9. 5.2 .1 Continuous Control System
• The objective is to maintain the value of an output variable at
a desired level similar to a feed back control system.
• Example :
Chemical reactions temperature ,pressure, flow rates
Work part position relative to cutting tool X,Y,Z values are
continuous
• Continuous control categories :
Regulatory control :
The objective is to maintain process performance at a certain level.
Compensation action is taken only after a disturbance has affected
the process output

17. On-Line Search strategies :
In case the relationship between input parameter and the index of
performance is unknown .Trial and error and other techniques
are used to find which input parameter affect IP, so as to
optimize it .
Continuous Control System
18. Changes are executed either due to a change of the state of
the system or because of elapsed time .
Event-driven changes:
Responds to some event that has changes the state of the
system ,such as presence of a part ,low-level of plastic
molding compound, counting parts on a conveyer belt.
19. Time-driven change :
Executed either at a specific time , or after a certain time lapes , such
as “Shop Clock” to start and end work , length of heat treatment ,..
A washing machine has both event-driven and time-driven changes
that control it.
Types of discrete control :
1- Combinational logic control :controls the event –driven changes.
2-Sequential control : manages time-driven changes .
20. A “real – time controller “ is a controller that is able to respond
to the process within a short enough time that performance is
not degraded .
21. Requirements for a real-time controller :
1- Process – initiated interrupts : (event – driven change )
The computer may interrupt execution of current program to
service a higher priority need of the process , often triggered by
abnormal condition .
2- Timer – initiated actions : ( time – driven change )
The controller must be capable of executing certain actions at
specified points in time. These actions could be : scanning sensor
values …….
22. Switch on/off . Displaying data , recomposing parameter
Other requirements for a real – time control computer are :
Computer commands to process , low – priority system and
program – initiated events , and Operator – initiated events .
Requirements for a real – time controller :
23. * Polling ( Data Sampling ) : ( Scanning )
Periodic sampling of data that indicates the status of the process .
Issues related to polling :
1
1. Polling frequency : = -------------------------------------------------
Time interval between data collection
2. Polling order : Sequence of different data point
3. Polling format : The manner in which the sampling procedure is
designed .
24. The alternatives include :
(a) Entering all new sensors data every polling cycle
(b) Updating the control system only with data that have changed .
(c) Using high-level scanning : Collecting only certain key data.
Using Low-level scanning : Collecting more complete data .
Using conditional scanning : Collecting more complete data if
necessary .
25. * Interlocks
Safeguard mechanism for coordinating the activities of devices
sequence of activities.
Input interlock : ( a signal from a sensor / machine to the
controller ) proceed work cycle , interrupt the work cycle
for some reason . Ex.: washing machine door.
Output interlock : a signal from the controller to an external
device to control its activities .
26. Interrupt System
Permits the execution of the current program to be suspended to
execute another program in response to a higher priority event.
Ex.: pushing keyboard key.
27. Priority Level ( ranking ) Computer Function / Control Function
1- ( lowest priority ) Most operator inputs
2- System & program interrupts
3- Timer interrupts
4- Commands to process
5- Process interrupts
6- (highest priority ) Emergency stop ( operator input )
Priority levels in an Interrupt System :
28. Internal interrupts: generated by the computer itself.
External interrupts: process- initiated and operator inputs.
A higher priority function can interrupt a lower priority
function.
A function at a given priority level cannot interrupt a function
at the same priority level.
Interrupt System
29. Single-level interrupt system has only two modes of operation;
normal mode and interrupt mode.
• If higher priority signal arrives after a lower priority signal, it has
to wait .
Multilevel interrupt system has a normal operating mode plus more
than one interrupt level (with relative properties).
• If higher priority interrupt signal arrives after a lower priority
interrupt, it will override it and its task serviced first.
Interrupt System
30. Exception Handling (Error detection & recovery ):
An exception is an event that is outside the desired operation
of the process.
e.g. Production quality problem, variables outside normal
ranges shortage of raw materials, hazard conditions, controller
malfunction…..
32. Computer process monitoring
• Control remains in the hands of humans.
• Categories of data collected by the computer:
1. Process data: input parameters, output variables, …..
2. Equipment data: status of the equipment in the work cell, machine
utilization, schedule, tool changes, diagnosis,…..
3. Product data: maybe required by regulations for the firm own use.
data may be entered manually or automatically
33. Direct digital control (DDC)
No longer used today! It was a transitional phase in computer
process control.
It was an improvement on the analog control loop.

36. Improvement to the DDC system include
1. More control options than traditional analog, such as on/off or
nonlinear functions.
2. Integration and optimization of multiple loops. Such as feedback
measurements integration.
3. Ability to edit the control programs, more flexibility to reprogram,
no need for hardware changes as in analog control.
37. Numerical control and robotics
Numerical control (NC): a microcomputer directs a machine
tool through a sequence of steps defined b y a program of
instructions.
Industrial robotics: the joints of the robot arm are controlled
to move the end of the arm through a sequence of positions
during the work cycle.
38. PLC )Programmable logic controller)
Introduced in 1970 as an improvement on the
electromechanical relay controllers used to implement
discrete control.
A PLC is a microprocessor-based controller that uses stored
instructions to implement logic, sequencing, timing, counting,
etc…for controlling machines and processes . It’s used for
both continuous and discrete control
39. Supervisory control, e.g. SCADA (Supervisory Control And Data Acquisition)
It corresponds to cell or system level control (higher level
than NC and PLC)
It is superimposed on those process-level control systems
(NC and PLC).
Has economic objectives.
Could be regulatory control, feed forward control, or optimal
control.

• Multiple microcomputers are connected together to share and
distributed the process control work load.
• component and features:

43. Can be enhanced in the future (after installation ).
Parallel multitasking is possible with multiple computers.
It has built-in redundancy.
Control cabling is reduced compared with central control.
Networking facilitates plant management.
Example : Multiple PLC’s through a factory, connected by
network.
Benefits and advantages of DCSs :
44. PCs in Process Control
Categories of PC implementations in process control:
1. Operator Interface: The PCs interfaced to one or more PLCs
or other devices that directly control the process.
Advantages :
- The PC is user-friendly.
- It can be used for other functions.
- The failure of the PC does not disrupt the PLCs functions.
- Can be easily upgraded.
45. 2. Direct Control: The PC is interfaced directly to the process and
controls its operations in real-time.
Problems :
- If the PC fails, the process fails.
- PC is not designed for process control.
- PC is designed to be used in an office environment.
PCs in Process Control
46. However, There is a trend for PC deployment for direct control due
to several factors :
• Wide-spread familiarity with PCs.
• Availability of high performance PCs.
• “Open architecture philosophy” in control systems design, which
means procuring hardware and software from a diverse pool of
vendors; not getting the whole system from the same supplier.
PCs in Process Control
47. Availability of PC operating systems that facilitates real-time control,
multitasking and networking.
Industrial-grade PCs can be used to cope with the harsh factory
environment.
Data integration is easier using one PC than using a PC and a PLC.
PCs in Process Control
48. Enterprise-Wide Integration of Factory Data:
It entails less management levels and more empowerment of
front line workers.
Enterprise Resource Planning (ERP) is a software that
achieves company-wide integration of all business
functions, including factory data.
A key features of ERP is the use of a single central database
that is accessible from anywhere in the company.
49. Capability resulting from integrating process data:
1. Managers have direct access to factory operations.
2. Production planners have access to most current data on
production to help in scheduling future orders.
3. Sales personnel can provide realistic delivery dates.
4. Customers can track the status of their orders.
5. Quality performance is more predictable.
6. Production cost accounting can be updated.
7. Production personnel have access to product design.
