Performance optimization of thermal systems in textile industriesIOSR Journals
Energy consumption has been growing very rapidly due to population growth, rapid urbanization
and industrial development. For future planning, it is important to know the current specific energy
consumption and the energy intensity in order to estimate future energy consumption. In the industrial sector
especially in textile units’ large amount of energy wasted due to improper working and lack of energy saving
measures. In this study, the various measures that causes the main energy losses are investigated .In the textile
dyeing sector, the main processes are associated with steam in various proportions. For the steam production,
steam boilers of different types are used for different applications. The efficiency of the boiler varies from one
industry to other based on various parameters such as quality of the water, fuel used, blow down quantity, etc.
Steam traps are also having influence on the boiler efficiency. In the case of steam leakage the performance of
the system decreases as the consumption of fuel increases to produce more steam. Thus by adopting various
recovery methods we can reduce the energy losses and fuel consumption.
The document compares different processes for removing moisture from transformers to increase their efficiency. Conventionally, thermal heating has been used, but it is not very energy efficient. Vacuum drying improves on this by applying a vacuum along with heating. A newer method is vapor phase drying, which heats the transformer using the vapor of a low viscosity solvent instead of air, potentially providing a more effective and efficient drying process. The paper analyzes the basics of insulation drying, drying time, conventional vacuum drying, and the vapor phase drying method in order to evaluate vapor phase drying against traditional techniques.
Performance Test on Mixed Refrigerant in Domestic RefrigeratorIJERA Editor
Refrigerator is a household appliance used to preserve the foods, vegetables, beverages at low temperature. Refrigerant is the blood of the refrigerator and it changes its phase to transfer heat for giving cooling effect inside the refrigerator. Generally many refrigerator works under the vapour compression cycle and it uses only one refrigerant. Each and every refrigerant used in the refrigerator must have disadvantages, to overcome this problem we use mixed refrigerant (two different refrigerants with different properties are mixed together). In this project combination of R600a (isobutane) and R134a (1, 1, 1, 2-tetrafluroethane) is selected as a mixed refrigerant. R600a have some good properties like zero ODP, zero GWP and high latent heat of vapourization and R134a is non-toxic, non-flammable, non-corrosive and zero ODP.

Production Integrated Vacuum Heat Treatment Systems in the Automotive IndustryALD Vacuum Systems Inc.
To secure the required properties of highly stressed parts from the automotive industry these parts need to be heat treated, in many cases case hardened. This is traditionally performed in central hardening shops. However, the separation between machining and heat treatment involves great efforts regarding transport and buffering of parts leading to extended throughput times and therefore additional costs.

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.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
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.

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%.

energy rating
Energy Savings and Highest Efficiency at the Same Time
In order to compare between the different sizes of dryers, WITTMANN
needed to find one common property relative to the dryer size. Air flow was
selected as it is based on the dryer size and was specifically determined by
the measurement of the actual mass flow of air. Then, simply put, WITT-
MANN defined the actual energy rating as the basic energy consumption
per mass flow of air. To further test the validity of their results, WITTMANN
compared actual test results with theoretical values. Once tested, every
dryer model is labeled with an Energy Sticker showing the measured test
result in terms of kWh per unit weight of dry air.

Efficient Material
Management
The placement of the dryer and drying hoppers on a
mezzanine above the gaylords and material supply bins
guarantees the optimized usage of available space as well
as shortest conveying distances for the filling of the drying
hoppers.
The perfect geometry of the drying hoppers and the discharge
cone, which has been designed for uniform material flow, are
perfectly suited for the drying of virgin and regrind material.
Flexible and Modular
Construction
The modular drying hopper series SILMAX with separate
tables enable a flexible combination for the respective drying
demand. Even when the requirement changes over time the
SILMAX drying hoppers can be arranged differently and new
hoppers can be added, as long as the dry air supply of the
dryer series DRYMAX is sufficiently sized.
Optional level sensors in the FEEDMAX vacuum loaders
calculate and monitor by means of the WITTMANN M7.3 IPC
control system any excessive dried material demand in each
drying hoppers and respond according to the users instruc-
tions.
Intelligent
air distribution
The intelligent SmartFlow air distribution of each SILMAX
drying hopper adjusts the air supply to the actual material
demand of the respective SILMAX hopper.
Thereby a high quantity of drying hoppers can be connected
to a dryer and still guarantee an efficient and perfect drying
process.
