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.

Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.
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%.

12. The pile can take load vertically end bearing and also by skin friction.
When the soil bearing capacity was not sufficient for carrying the
design load by the column footing that is why the pile foundation was
preferred for constructing a multistoried building in such a soil
condition.
Now Dominage Consultancy Ltd of “Dominage Group” is preferred to
construct the cast-in-site pile at Dominge Heaven.
12
13. When A pile develops the upward pressure on
its skin surface against the super imposed load
this is called skin friction.
Now we can say the skin friction of pile is
transferring the loads to the soil by the surface
of the pile.
In the design time we must have to care full about
skin friction value because it must be grater
then design load.

29. In the Bangladesh most commonly useable process is percussion boring
process for cast in situ pile.
◦ Boring operation
◦ Borehole stabilization
◦ Preparation of reinforcement casing
◦ Placement of the rebar case into the borehole
◦ Concreting into the borehole.
29
30. Boring operation:
At first, according to the pile layout plan the
locations of the center of the piles are selected
carefully on the ground.
Before starting the boring work we must have
to do the investigation of cast-in-situ pile the
construction site.
Then set the tripod and drill bit on the top of
the pile point center. Then top of the drilling
pipe adjusted with a head where a hose pipe is
connected from the centrifugal pump.
That pump is always circulating the drilling
fluid from the settling tank to maintain the
properties of drilling fluid during borehole
operation.
30
31. Borehole stabilization:
The drilling purpose fluid is used for hole or loose the inside soil of
borehole.
In percussion boring one subjects is must follow is that fresh water should
not be used as a drilling fluid in boring operation.
For maintain the better quality bentonite is used as admixture with
drilling fluid inside the borehole.
After that it should be washed properly not more or less.
When we will see no cutting material mixed with the wash water we have
to stop the washing.
Then we can tell that the borehole is totally washed.
31
32. Preparation of reinforcement casing:
This work is must be done by the expert
labor.
The reinforcement case made by expert
because the longitudinal bars are cut
according to the measurement of the
structural drawing and it is bound with
wire and welded properly with electrodes
on a temporary hanger.
There are 8 mm to 10 mm 40 graded rod is
used as spiral stirrup.
To make the spiral ring the pile drum is
used in the field.
After the boring operation we should
have to place the reinforcement case as
soon as possible.
32
33. Placement of the rebar case into the borehole:
After ready the reinforcement case engineer must check the rebar case
is properly bound and welded.
The engineer has to be careful about the place, through which the
rebar case will be pulled over the borehole.
The rebar case should be placed by its self weight not by providing any
extra force.
If the rebar case is placed by any external force then there is a
possibility of caving or misguiding the rebar case inside the borehole.
In reinforcement case we should give the proper clear cover.
Finally the rebar case should have to hang with the case pipe .
Otherwise it will be grounded into the bore hole bottom which will be
very harmful for pile.
33
35. Concrete on the borehole:
Finally we have to place the concrete on the borehole.
For this work we are use the trimmi pipe, funnel, bucket etc.
We should not wait so long because then there is a possibility of caving
or settling inside by the suspended particles.
After discharge the concrete from the bucket then that time trimmi pipe
and funnel have to move up and down that time it cleaned properly.
From this up and down process concrete will be compressed.
Finally the concreting case pipe will be withdrawn carefully so that
there is no chance for withdrawing the concrete or the rebar casing.
35
37. The proportion of the concrete was not maintained carefully.
Stone chips is not well graded and not bolder crash.
Trimmi pipe was divided from the joint.
Safety and security is not proper maintained.
Rebar case was displaced from the same position.
Rebar case caring time happen some accident.
Fast aid box is not available in the projects.
Pile caving occurred during replacing rebar case for two piles.
37
39. To the mixing time we have to careful for supervision.
Stone chips must take the bolder crashed.
Before joint must cheek the threat of the trimmi pipe.
Rebar case replace time we should be very careful about the accident.
Fast aid box must have to stoke in the site.
Washing time must have to care about the boring fluid.
39
40. To understand the layout and project preparation
are very important in any construction.
To supervision of cast in situ pile & design work in
an appropriate manner.
To control the quality of cast in situ pile.
Otherwise our dreams will not comes in true.
