This document summarizes the precast segmental construction method for bridges. It was first used in Western Europe in the 1950s and involves casting concrete segments off-site, transporting them to the construction location, and erecting them using various methods like balanced cantilever, progressive placement, span-by-span, or incremental launching. Machinery like launchers, girders, cranes, and hydraulic jacks are used for erection. Additional steps include external prestressing and grouting. Precast segmental construction allows for longer spans, faster construction times, increased quality control, and is most suitable for long bridges.
Segmental bridge construction involves building bridges out of precast concrete segments. This allows for longer spans than traditional methods by reducing the need for intermediate piers. There are several techniques for segmental bridge construction including cast-in-place using form travelers, incremental launching where segments are cast and then pushed out over supports, and precast segment erection using launching girders. Segmental construction enables building bridges more quickly and over existing infrastructure with minimal traffic disruptions.

The document provides details about the construction of a flyover bridge along the SP Ring Road in Ahmedabad, India. Some key details include:
- The project involves constructing a 1,415 meter long flyover bridge with 30 piers and 32 pile caps.
- Pile construction is a major aspect of the project, with 408 piles of 1,200 mm diameter being constructed using a hydraulic rig by boring and concreting.
- Other construction activities discussed include pile cap construction, pier construction, road construction and the use of various equipment.
- The flyover is expected to improve connectivity and prevent traffic congestion along the busy SP Ring Road in Ahmedabad.
The balanced cantilever method is used to construct bridges with spans between 50-250m. It involves erecting segments on each side of the pier in a balanced sequence to minimize load imbalance and bending in the piers. This method is advantageous for long spans, marine environments, and where access under the deck is difficult. The cantilever lengths are typically 0.20-0.30 of the main span. Segment construction proceeds until the midspan point is reached, where the balanced pair is closed. The key advantages are single-sided support during construction and uniform construction. However, it is also very expensive and complicated to construct.
This document discusses different types of overhead cranes called EOT cranes. It describes single girder EOT cranes that can lift up to 20 tons and have a span of up to 40 meters, and double girder EOT cranes that can lift up to 200 tons and have a span of up to 65 meters.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.

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.

square or to serve workstations.
The jib cranes are characterized by three functions:
• lift vertically a load by means of a unit that generally consists of a chain hoist and
specific lifting accessories;
• move the load by means of a trolley, electric or manual, that runs on the arm of the
jib crane;
• rotate the load around the rotating axe of the arm by means of the pushing force of
the load itself, serving the underlying circular area, bounded by the rotating radius
of the arm.
The jib cranes in “Column mounted” execution are generally provided for fixing to the
ground; the self-supporting column can be fixed to the ground by means of stay bolts,
on suitable foundation plinth or, after having checked the suitability, with chemical bolts
with suitable counter plate.

Device for adjusting the flatness of arms overbraced version.
The system allows to set the best value of counterslop of the arm according with the
deflection caused by the arm lenght itself and from the height of any column.
Reduction of the pushing forces and noise in the traverse movements.
The low friction between the wheels and the sliding surfaces they are located in,
gives the maximum smoothness and quietness in the push trolleys movement.
In fact the high quality and resistance beams used for the arms are selected with
tight tolerances and subjected to sandblasting cycles and are therefore marked by
sliding surfaces with low roughness.
Furthermore, to have high smoothness and quietness, the push trolleys, up to 1.000
kg capacity, are provided with wheels in polyamide resin rotating on self-lubricated
ball bearings and are provided with guide rollers, in order to avoid any shaving
friction.
Optimization of time and costs of regular inspections of the trolleys.
As the wheels of the trolleys run on the flange of the beam of the arm, they are easily
inspected without disassembly.
6. 6
Modular design with modular elements.
The system allows to:
• Have simple and compactable elements, disassembled, easy to be packaged,
characterized by regular and elementary shapes (such as parallelepipeds) and,
therefore, easily and economically handled and delivered.
• Semplify and secure the installation steps of the single elements composing
the over-braced arm, in different executions of column-mounted or wall-mounted
jib cranes.
• Reconfigure and redeploy the jib crane, also after the purchase, following any
user’s requirement , thanks to a modular design and the use of profiled beams for
the arms construction.
For instance it’s always possible(in any time and directly on site) to:
- Replace the push trolley with an electric one;
- Electrify the rotation of the arm with the aid of a dedicated “kit”.

The jib cranes VHT “VB” series are designed and classified in consideration of standard
EN 13001-1, in order to operate according to the parameters relating to the service
group A5 of ISO 4301-1.
In order to choose the right jib crane for the required service it’s important to consider
the following factors:
1. The capacity of the jib crane: is determined by the maximum load to lift
2. The loading rate (Q): is the stress level due to percentage of use of the capacity
(average of the loads to be lifted)
3. The functional parameters: are the operating conditions characterizing the use
of the jib crane or:
a. Functional dimensions: the height of the arm (determining the lifting height of
the hoist) and its cantilever (outreach) must be selected in order to ensure the
functional coverage of the space to be served, in consideration of neighboring
space;
b. Type of load: if it’s delicate or less, determines for its positioning the choice of
the speed of movement (lifting and translation) more suitable. In some cases it
is necessary to use a two-speed hoist with slow speed positioning.
c. Area of use: the jib crane is characterized by its conception, by intrinsic high
elasticity that is even more evident when it is used to handle loads close to the
maximum capacity and/or with mainly location in the top of the arm.
d. Ambient condition of use: the jib cranes are designed for indoor use and /
or covered area, protected from the weather and in absence of wind. In case
of outdoor use measures must be taken in relation to the surface treatment
(sandblasting - painting) as well as a parking brake arm and a suitable protection
cover for the trolley hoist.
e. Frequency and mode of use: determine the correct choice of the type
of translation and rotation, which can be manual or electrical in relation
to the characteristics of the load to be handled and the frequency of use.
If the use is very heavy (frequent and/or repeated switching) with loads close
to the maximum capacity, the resulting tiring of the operator due to manual
handling must be evaluated, in consideration of the recommendations referred
to the following table

• Height of the work level and load level;
• The dimensions and the weight of the parts to be installed, as well as the
available spaces for the handling of the parts to be installed.
Before starting with the assembling of the parts and with the installation of the jib crane,
the installer has to be sure that the characteristics of the crane are suitable with the use
which is intended for, and in particular:
• The capacity of the crane is ≥ compared to the load to lift.
• The characteristics of the fixing structures (plinth, floor, pillar, wall, etc.) have
been “Declared suitable” by the Customer or by an “Expert engineer”, engaged
by the Customer .
• The characteristics of the lifting unit (trolley/hoist), if not part of the supply, are
compatible with those of the jib crane in relation to:
• capacity of the hoist ≤ than capacity of the jib crane;
• weight of the trolley/hoist ≤ than maximum ones intended;
• lifting and transverse speed ≤ than the maximum ones allowed;
• headroom of the figure of trolley/hoist ≤ than those allowed;
• reaction on the trolley wheels than to the maximum ones intended;
• the flange width of the beam must correspond to the provided one for the
wheels of the trolley.
• The installer must follow the instructions content in the user guide of the jib crane
and relative hoist.
Set up-Ready to use
Following the installation activities of the Jib cranes “VB” series it is the precise duty
of the installer to:
• Lead the activities of the set-up service as described in the User Guide, ensuring
that all the safety devices are properly installed and corresponding to the intended
use and provide, if necessary, to their adjustment.
• In particular, the installer must be sure about the right installation and functionality
of the limit switch of:
• Transverse: end stop of the trolley, must be fixed in order to avoid interference
and/or collision of the lifting unit (trolley and hoist) with the structures of the jib
crane itself;
• Lifting: limit switch of the hoists must be adjusted in order to avoid the hook
contact with the floor;
• Rotation: arm rotating limit device of the jib cranes must be adjusted in order to
avoid interference and/or collisions between the arm in rotation and structures
on its way.
• Prepare the report “Testing and correct installation” of the jib crane, deliberating
the suitability for use
• Take care of the complete editing of the responsibility of part as intended in the

Jib crane for which in case of fixing to the floor with chemical bolts, is mandatory the use of counter plates as referred on pag. 20
Note:
• The values given are based to static reactions (calculated for column with basic height H, as referred on pag.12 and 13) and must be multiplied with the proper dynamic
coefficients Φ and compounds according the load combinations stated in the standards used for the calculation (example EN 13001-2).
• The reactions are divided into the parts due to load Q and crane weight G to allow the designer of the fixing structures of the jib crane, a right evaluation applying to each
of them the relative partial safety coefficient γp.
• The check of the fixing structures of the jib cranes must be carried out by expert engineers which give the suitability and will officially take on the responsibility.
Example: composition of the reactions as described in the Standard EN 13001-2.
It is considered a jib crane with overbraced arm of capacity 500 kg, arm 5 m and column height 5,5 m.
From the table we obtain the following static reactions due to crane weight: Mr(G)
= 5,3 kNm, Rv(G)
= 3,6 kN.
From the table we obtain the following static reactions due to load: Mr(Q)
= 30 kNm, Rv(Q)
= 5,7 kN.
According to Standard EN 13001-2 the composition of the reactions by multiplying each part for its relative dynamic coefficient and its partial safety coefficient to obtain
the design values:
MrEd
= Φ1
γp(G)
Mr(G)
+ Φ2
γp(Q)
Mr(Q)
RvEd
= Φ1
γp(G)
Rv(G)
+ Φ2
γp(Q)
Rv(Q)
As defined in Standard EN 13001-2 can take on the following factors:
γp(G)
= 1,16 (masses with unfavorable distribution type MDC1)
γp(Q)
= 1,34
Φ1
= 1,1
Φ2
= 1,33 (value for the overload clutch calibration of the electric chain hoists VHT “VK” series).
NB: for the value of the coefficient φ2 is recommended ascribed, prudently in favor of safety, to the overload clutch calibration stated by the Manufacturer of the installed
hoist. Without data, the Standard EN 14492-2 indicates the maximum overload clutch calibration of 1,6.
From the composition of the reactions there are to the base of the column: MrEd
= 60,2 kNm e RvEd
= 14,7 kN
As indicated by the Standard EN 13001-2 the obtained values should be compared with their resistance values MrRd
and RvRd
obtained from characteristics value of resistance of
the material through a reduced coefficient of resistance γm
= 1,1.

Note:
• The values given are based to static reactions (calculated for column with basic height H, as referred on pag.12 and 13) and must be multiplied with the proper dynamic
coefficients Φ and compounds according the load combinations stated in the standards used for the calculation (example EN 13001-2).
• The reactions are divided into the parts due to load Q and crane weight G to allow the designer of the fixing structures of the jib crane, a right evaluation applying to each
of them the relative partial safety coefficient γp.
• The check of the fixing structures of the jib cranes must be carried out by expert engineers which give the suitability and will officially take on the responsibility.
Example: composition of the reactions as described in the Standard EN 13001-2.
It is considered a jib crane with overbraced arm of capacity 500 kg, arm 5 m and column height 5,5 m.
From the table we obtain the following static reactions due to crane weight: Mr(G)
= 5,3 kNm, Rv(G)
= 3,6 kN.
From the table we obtain the following static reactions due to load: Mr(Q)
= 30 kNm, Rv(Q)
= 5,7 kN.
According to Standard EN 13001-2 the composition of the reactions by multiplying each part for its relative dynamic coefficient and its partial safety coefficient to obtain
the design values:
MrEd
= Φ1
γp(G)
Mr(G)
+ Φ2
γp(Q)
Mr(Q)
RvEd
= Φ1
γp(G)
Rv(G)
+ Φ2
γp(Q)
Rv(Q)
As defined in Standard EN 13001-2 can take on the following factors:
γp(G)
= 1,16 (masses with unfavorable distribution type MDC1)
γp(Q)
= 1,34
Φ1
= 1,1
Φ2
= 1,33 (value for the overload clutch calibration of the electric chain hoists VHT “VK” series).
NB: for the value of the coefficient φ2 is recommended ascribed, prudently in favor of safety, to the overload clutch calibration stated by the Manufacturer of the installed
hoist. Without data, the Standard EN 14492-2 indicates the maximum overload clutch calibration of 1,6.
From the composition of the reactions there are to the base of the column: MrEd
= 60,2 kNm e RvEd
= 14,7 kN
As indicated by the Standard EN 13001-2 the obtained values should be compared with their resistance values MrRd
and RvRd
obtained from characteristics value of resistance of
the material through a reduced coefficient of resistance γm
= 1,1.

The jib cranes with articulated arm, "VB-S" series, hand-pushed within a range of
360°, are available both in “Column” and “Wall mounted” execution.
They represent the ideal way for moving materials in a workplace with obstacles that can
be a hindrance to the free rotation of the arm, in case the arm was made from a single
rigid element.
The "Articulated" jib cranes have an arm made of two segments rotating independently
from each other, so to avoid the collision with fixed obstacles in the rotating field.
The "VB-S" series jib cranes wit articulated arm are available as standard for the following
capacities and arms:
• jib cranes with capacities of 125 kg, 250 kg and 500 kg, with arms ranging
from 3 to 7 m;
• jib cranes with capacity of 1000 kg, with arm ranging from 3 to 5 m.
NOTE:
technical specifications, dimensions and weights are available on request.
The jib cranes with electric rotation on slewing bearing series "VB-R", are used
to handle loads where manual handling operations is difficult or dangerous and, in
particular, where:
• The load is heavy and requires excessive pulling forces (e.g. for capacities in
access of 2.000 kg)
• The shape and / or the nature of the load makes the handling dangerous (e.g.
warm materials)
• The size of the load makes it difficult to oversee (e.g. bulky goods)
• The area of operation and use is prohibited or impassable (e.g. hauling
operations / launching boats).
VB-R electric rotation:
• The WLL from 2.000 up to 20.000 kg
• The arm length from 4 to 12 meters
NOTE:
technical specifications, dimensions and weights are available on request.
