Quality of service performances of video and voice transmission in universal ...journalBEEI
The universal mobile telecommunications system (UMTS) has distinct benefits in that it supports a wide range of quality of service (QoS) criteria that users require in order to fulfill their requirements. The transmission of video and audio in real-time applications places a high demand on the cellular network, therefore QoS is a major problem in these applications. The ability to provide QoS in the UMTS backbone network necessitates an active QoS mechanism in order to maintain the necessary level of convenience on UMTS networks. For UMTS networks, investigation models for end-to-end QoS, total transmitted and received data, packet loss, and throughput providing techniques are run and assessed and the simulation results are examined. According to the results, appropriate QoS adaption allows for specific voice and video transmission. Finally, by analyzing existing QoS parameters, the QoS performance of 4G/UMTS networks may be improved.

An Approach to Detecting Writing Styles Based on Clustering Techniquesambekarshweta25
An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap
-Shweta Ambekar
-Harshit Singh
-Nakul Sharma (Assistant Professor)
Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.
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.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

aeronautical networks is considered to be achieved by satellites with large coverage areas
especially over oceanic regions during long-haul flights. The services concept needs to take
into account today’s peculiarities of satellite communication ,it must with available or in near
future ,thus the bandwidth that is requested to the available standard interfaces of the wireless
standard needs to be adapted to the available bandwidth (typically :432kb/s down link,144kb/s

5. FATHER OF AERONAUTICAL
COMMUNICATION
• 1.The father of aeronautical communication is GEORGE CAYLEY.
• 2.He was born on 27 December 1773 in Scarborough Yorkshire , England,
Kingdom of Great Britain and his death occurred in 15 December 1857 in
Brompton , Yorkshire ,England, United Kingdom.
• 3.He was a British citizenship ,Nationality was English , and his fields were
Aviation ,Aerodynamics , Aeronautics ,Aeronautical Engineering.
• 4.He known for designed first successful human glider , discovered the four
aerodynamic forces of flight weight , lift , drag , thrust and cambered wings
, basis for the design of the modern aeroplane . He were the first person to
understand the underlying principles and forces of flight.
6. TECHNICAL OVERVIEW
• 1 UTMS –The universal Mobile Telecommunication System (UTMS) is the third
generation mobile communication system being developed within the IMT -2000
framework .
• 2.UTMS will build on and extend the capability of today’s mobile technology
(like digital cellular and cordless ) by providing increased capacity ,data capacity
,data capability and a far greater rang of services.
• 3.Blutooth operates in the unlicensed 2.4-GHz ISM (industrial , Scientific and
medical ) band and uses a frequency –hopping spread spectrum (FHSS)
technique to minimize interference. A Bluetooth unit has a nominal rang of
approximately 10 meters .
• 4.IEEE802.11B-Wireless local area networking (WLAN) radio technology
provides superior bandwidth compared to any cellular technology. The IEEE
802.11b standard offers a maximum throughput of 6.5 Mbps working in the
same 2.4 GHz ISM band as Bluetooth by the use of sequence spread spectrum
(DSSS).
7. CABIN ARCHITECTURE
• 1.So far, GSM telephone is prohibited in commercial aircraft due to the uncertain
certification situation and the expected high interference levels of the TDMA
technology.
• 2. With the advent of spread spectrum systems such as UMTS and W-LAN, and low
power pico –cell access such as Bluetooth this situation is likely to change
,especially if new aircraft avionics technologies are considered, or if the
communications technologies are in line with aircraft development as today.
• 3.When wireless access technologies in aircraft cabins are envisaged for passenger
service, the most important standards for future use are considered to be: UTMS
with UTRAN air interface, BLUETOOTH , and W-LAN IEEE 802.11b. Of course,
these access technologies will co-exist with each other, beside conventional IP fixed
wired networks.
• 4. The wireless access solution is compatible with other kinds of IFE ,such as live
TV on board or provision of internet access with dedicated installed hardware in
the cabin seats . Hence ,it should not be seen as an alternative to be seen as an
alternative to wired architecture in an aircraft, but as a complementary service for
the passengers.
8. SATELLITE CONNECTION
• 1.Connection to telecom networks is considered to be achieved by
satellites with large coverage areas especially over oceanic regions
during long haul flights.
• 2. The service concept needs to take into account today’s peculiarities
of satellite communication , thus it must cope with the available or in
near future available satellite technology, and inter working must be
performed at aircraft interface level with the satellite technology.
• 3. Currently, few geostationary satellites such as the in mars at fleet are
available for two-way communications, the cover the land masses and
the oceans.
• 4.Ku-band may be used on a secondary allocation basis for
aeronautical mobile satellite services (AMSS) but bandwidth is scarce
and coverage is mostly provided over continents.
• 5.K/Ka-band satellites will be launched in the near future , again here
continental coverage is mainly intended.
9. SERVICE INTEGRATOR
• 1.The different wireless access services of UMTS ,W-LAN and
Bluetooth require an integration of services over the satellite .The
central part of service portfolio provisioning is the service
integrator (SI).
• 2.The service integrator will provide the interfaces for the wireless
and wired service access points in the cabin ,as well as the
interfaces to the terrestrial networks at aircom provider site .
• 3.All services will be bundled and transported between a pair of
service integrators. It performs the encapsulation of the services
and the adaptation of the protocols.
•
10. INTERFERENCE
• 1.Once the earlier described measurement finish ,four types of interference within the CMHN have to
be studied: the co-channel interference among the terminal of different wireless access segment.
• 2.The inter-segment interference between terminals of different wireless networks ,the cumulative
interference of all simultaneous active terminals with the aircraft avionics equipment and the
interference of the CMHN into terrestrial networks.
• 3.From the co-channel interference analysis the in-cabin topology planning will be derived .For this
reason it is important to consider different AP location during the measurements.
• 4.It is not expected to have major problem due to interference from UTMS towards WLAN and
Bluetooth ,thanks to the different working frequency ,on the other hand ,particular interest has to be
paid in the interference between Bluetooth and WLAN.
11. COLLECTIVELY MOBILE
HETEROGENEOUS NETWORK
• 1. The concept of having several users, Which are collectively on the
move forming a group with different access standards into this group,
is called Collectively Mobile Heterogeneous Network (CMHN).
• 2. In such a scenario one can find two types of mobility and two types
of heterogeneity : the user mobility inside the group from one side.
• 3. Heterogeneous access segment and heterogeneous user access
standards from the other side.
• 4. The aircraft cabin represents a CMHN supporting three types of
wireless (user mobility) access standards (heterogeneous user access )
inside an aircraft (the mobile group ) using one or more satellite
access segment.
12. ROLL OF SATELLITE IN FUTURE
• 1. AERONAUTICAL MOBILE SATELLITE SERVICE (AMSS)but bandwidth is scarce and coverage is
mostly provided over continents . K/K a-band satellites will be launched in the near future again here
continental coverage is mainly intended. Mobile satellite system will very important for us if it will be
available for us because if we stayed in Aeroplane important persons can call someone to call to for any
emergency.
• 2. Currently , in continental areas, mobile communications use a narrowband VHF voice system
combined with a VHF digital data link e.g. VDL (VHF Digital link ) mode 2.The VHF network is
composed of terrestrial antennas connected with gateway routers to a backbone network in which the
service are located . VHF is a very mature and reliable technology, it presents some disadvantages , it
requires several remote ground stations to achieve the coverage that implies high operating cost due
to links between ATC center and remote radio stations.
• 3. The efforts described above have led to the understanding of aeronautical of aeronautical
communications research and technology development needs for ATM applications described next .And
that the refining and updating of these needs will be an on-going process as new information is gained
through studies ,modeling and simulation tests and experimentation.
13. CONCLUSION
1. From the users point of view ,their service acceptance will be increased by the following facts: they can be
reached under their usual telephone number .
2. They may be have available telephone numbers or other data stored in their cell phones or PDAs, their laptops
have the software they are used to ,the documents they need and with their personalized configuration (starting web
site , bookmarks, address book).
3. In addition ,since users in an aircraft are passengers, the electronic devices they carry with them, is wireless ,like
laptops with WLAN interface.
4. Currently, One of the major IFE costs is due to film copies and delivery expensive of new movies. Hence , it
should not be seen as an alternative to a wired architecture in aircraft, but as an added service for passengers.
