CW RADAR, FMCW RADAR, FMCW ALTIMETER, AND THEIR PARAMETERSveerababupersonal22
It consists of cw radar and fmcw radar ,range measurement,if amplifier and fmcw altimeterThe CW radar operates using continuous wave transmission, while the FMCW radar employs frequency-modulated continuous wave technology. Range measurement is a crucial aspect of radar systems, providing information about the distance to a target. The IF amplifier plays a key role in signal processing, amplifying intermediate frequency signals for further analysis. The FMCW altimeter utilizes frequency-modulated continuous wave technology to accurately measure altitude above a reference point.

Our project explains about the student management. This project mainly explains the various actions related to student details. This project shows some ease in adding, editing and deleting the student details. It also provides a less time consuming process for viewing, adding, editing and deleting the marks of the students.
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.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
We have compiled the most important slides from each speaker's presentation. This year’s compilation, available for free, captures the key insights and contributions shared during the DfMAy 2024 conference.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

2. Transducers ?
A device which converts one form of
energy to another
A sensor converts the physical parameter to an electric
outputs
&
A actuator converts an electrical signal to a physical
outputs
SENSORS ACTUATOR

3. SENSOR ?
A sensor is a converter ,that
measure a physical quantity and
converts it into a signal which
can by an observer or by an
instruments
OR
A sensor is a device, which responds
to an input quantity by generating a
functionally related output usually in
the form of an electrical or optical
signals
4. Let’s explain the example of
temperature.
The mercury in the glass
thermometer expands and
contracts the liquid to
convert the measured
temperature which can be
read by a viewer on the
calibrated glass tube.
5. Sensors are used in everyday
objects such as touch sensitive
elevator buttons and lams which dim
or brighten by touching and many
more like in
cars,machines,aerospace,robotics,
manufacturing,industrial,airplanes,
communications(cellular telephones,
radios), electrical devices and many
countless other applications

14. Classification of Transducers
Transducers can be classified on five
basis:-
1. On the form of transduction used
2. As Primary & Secondary Transducers
3. As Passive & Active Transducers
4. As Analog & Digital Transducers
5. As Transducers & Inverse Transducers
15. On the Basis of transduction used :-
Transducer can be classified in to resistive,inductive,capacitive etc
depending upon how they converts the input quantity in to
Resistance,inductance,capacitance etc…
As Primary & Secondary Transducers:-
There are two stages of transduction,firstly the Pressure is
Converted in to a displacement by bourdon tube then the
Displacement is converted into analogous voltage by linear
Variable differential transformer(L.V.D.T),The Bourdon tube
Is Primary transducer & L.V.D.T called secondary transducer
As Passive & Active Transducer:-
Passive transducers uses the power from an external source & A part
Of it from the measurand quantity for the process of transduction
e.g- resistive,inductive,capacitive etc…
Active transducers self generate their own voltage or current output
They do not require the external power source
e.g- photovoltaic cells,thermocouple etc……
16. Analog & Digital Trnasducers
Analog transducers converts the input quantity into an
analog output which is continuous function of time
e.g- thermocouple,L.V.D.T
Digital transducers converts the input quantity in to an
electrical output which is in the form of pulses
Transducers & Inverse Transducers
Transducers is the device which converts non electrical
quantity in to electrical quantity
Inverse transducers is the device which converts electrical
quantity in to non electrical quantity
