The purpose of designing a controller for a
teleoperation system is achieving stability and high efficiency
in presence of factors such as time delay, noise, system
disturbance and modeling errors. In this article seven new
schemes for teleoperation systems is suggested to reduce the
error of tracking between the master and the slave systems. In
the first and second structures, optimal control is applied to the
master and in the third structure it is applied to the slave. In
the forth structure, optimal controller has been designed in
both the master and slave subsystems and by a suitable
combination of the output signals of both controllers and
exerting it to slave, it has been tried to create the best
performance with regard to tracking. In the 5th structure,
optimal controller is applied to both the master and slave
systems and the output of each controller is then applied to it’s
own system. In the structures 6 and 7, using optimal control
and wave transformation, it has been tried to reduce the
tracking error between the master and the slave systems which
is considered as the cost function in this article. In these two
structures, optimal controller guarantees the efficiency of the
system and wave variables method has been used to guarantee
the stability of the system for constant time delay. In this
method, the appropriate selection of weighting factors of cost
function and wave impedance plays a decisive role in the
improvement of system performance and reduction of tracking
error between the master and the slave.
Performance of mf msk systems with predistortion schemesIJMIT JOURNAL
Efficient RF power amplifiers used in third generation systems require linearization in order to reduce adjacent channel inter-modulation distortion, without sacrificing efficiency. Digital baseband predistortion is a highly cost-effective way to linearize power amplifiers (PAs). New communications services have created a demand for highly linear high power amplifiers (HPA's). Traveling Wave Tubes Amplifiers ( TWTA ) continue to offer the best microwave HPA performance in terms of power efficiency, size and cost, but lag behind Solid State Power Amplifiers ( SSAP's ) in linearity. This paper presents a technique for improving TWTA linearity. The use of predistorter (PD) linearization technique is described to provide TWTA performance comparable or superior to conventional SSPA's. The characteristics of the PD scheme is derived based on the extension of Saleh's model for HPA. The analysis results of Multi-frequency Minimum Shift Keying (MF-MSK) in non-linear channels are presented in this paper.
The document summarizes research on energy efficient hybrid precoding for simultaneous wireless information and power transfer (SWIPT)-enabled massive MIMO non-orthogonal multiple access (NOMA) systems. It proposes a novel approach using an analog circuit-embedded (ACE) algorithm to design the analog precoder based on a switch-incorporated (SI) architecture. The ACE algorithm uses a probabilistic model and smoothed updating procedure to generate the analog precoding matrix with elements of ±1/√N. Simulation results show the proposed method achieves higher spectral and energy efficiency compared to existing techniques.
Blind Estimation of Carrier Frequency Offset in Multicarrier Communication Sy...IDES Editor
Orthogonal Frequency Division Multiplexing
(OFDM) systems are very sensitive to carrier frequency offset
(CFO), caused by either frequency differences between
transmitter and receiver local oscillators or by frequency
selective channels. The CFO disturbs the orthogonality among
subcarriers of OFDM system and results intercarrier
interference (ICI), which degrades the bit error rate (BER)
performance of the system. This paper presents a new blind
CFO estimation scheme for single-input single-output (SISO)
OFDM systems. The presented scheme is based on the
assumption that the channel frequency response changes
slowly in frequency domain. In this scheme an excellent tradeoff
between complexity and performance, as compared to
existing estimation schemes, is obtained. The improved
performance of the present scheme is confirmed through
extensive simulations.

The low noise amplifier is one of the basic functional blocks in communication systems. The main interest of the LNA at the input of the analog processing chain is to amplify the signal without adding significant noise. In this work, we have modeled a LNA for radar reception systems operating around 11 GHz, using the technique of impedance transformations with Smith chart utility. The type of transistor used is: the transistor HEMT AFP02N2-00 of Alpha Industries®. The results show that the modeled amplifier has a gain greater than 20 dB, a noise figure less than 2 dB, input and output reflection coefficients lower than -20 dB and unconditional stability.

Correlative Study on the Modeling and Control of Boost Converter using Advanc...IJSRD
DC-DC converters are switched power converters. The converters are most widely used in research and industrial applications. The DC-DC Boost Converters are used to step-up the supply voltage given to the plant model. The main advantage of using the Boost Converters is that it works in the low voltage according to the design specifications. In order to regulate the uncontrolled supply of voltage, a controller has to be designed and modeled to stabilize the output voltage. Since the convectional controllers cannot work under dynamic operating conditions, advanced controllers are to be designed to overcome the problems. In this article, the advanced controllers such as NARMA-L2, Fuzzy Logic (FLC) and Sliding Mode Controllers (SMC) are implemented and their responses are compared using MATLAB.
Low complexity DCO-FBMC visible light communication system IJECEIAES
Filter Bank Multicarrier (FBMC) is a new waveform candidate in the visible light communication system (VLC). FBMC is a distinctive kind of multi-carrier modulation that can be regarded as an alternative to orthogonal frequency Division Multicarrier (OFDM) with CP (cyclic prefix). DCOFBMC (DC-bias optical FBMC) has recently been used in VLC, because it overcomes all defects in the optical-OFDM system and has high spectral efficiency. But at the same time the traditional DCO-FBMC suffers from high complexity due to the use of Hermitian Symmetry for real signal, by using 2Npoint subcarrier IFFT (Inverse Fast Fourier Transformer) in the modulator, and the output is N-point subcarrier FFT (Fast Fourier Transform) in the demodulator. In this paper, for the first time, the possibility of minimizing complexity and generating a real signal without the use of Hermitian Symmetry or any other technique has been verified. The proposed technology provides 50% of the size of the IFFT / FFT and this results in a significant reduction in power consumption and occupied chip area.

This document discusses advanced control strategies for processes with time delays, including dead time compensators and selective control. It describes the effects of dead time on process control and introduces the Smith Predictor technique for dead time compensation using a predictive model of the process. Examples are provided to demonstrate PID control performance with and without dead time. Causes of dead time and the impact of model errors on the Smith Predictor approach are also reviewed. Selective control techniques are presented as methods to handle processes with more control variables than actuators.
This document discusses ratio control and split range control strategies. It describes ratio control as using one uncontrolled stream to adjust the flow of a second stream to maintain a desired ratio between the two streams. Split range control involves splitting a controller's output between two or more control valves to sequence their operation over different ranges of the controller's output. Examples are given of using split range control to manage pressure in a separator by opening a flare valve or closing a fuel gas valve depending on the pressure level.

Centralized Optimal Control for a Multimachine Power System Stability Improve...IDES Editor
This paper introduces applying the wave variable method to reduce the effects of transmission delay in a centralized optimal control system for stabilizing a multimachine power system. The paper describes designing an optimal controller without delay which improves stability but deteriorates with transmission delay added. Applying wave variable transform at the control center and generators improves stability by reducing delay effects on control signals. Simulation results demonstrate the wave variable method enhances controller performance during faults compared to considering transmission delay alone.
Bilateral control of master slave manipulators with constant time delayISA Interchange
This paper presents a novel teleoperation controller for a nonlinear master–slave robotic system with constant time delay in communication channel. The proposed controller enables the teleoperation system to compensate human and environmental disturbances, while achieving master and slave position coordination in both free motion and contact situation. The current work basically extends the passivity based architecture upon the earlier work of Lee and Spong (2006) [14] to improve position tracking and consequently transparency in the face of disturbances and environmental contacts. The proposed controller employs a PID controller in each side to overcome some limitations of a PD controller and guarantee an improved performance. Moreover, by using Fourier transform and Parseval’s identity in the frequency domain, we demonstrate that this new PID controller preserves the passivity of the system. Simulation and semi-experimental results show that the PID controller tracking performance is superior to that of the PD controller tracking performance in slave/environmental contacts.

Optimal Control of a Teleoperation System via LMI- based Robust PID Controllersidescitation
This document summarizes a research paper that proposes a new robust PID controller for a teleoperation system using an LMI (linear matrix inequality) approach. The controller aims to achieve transparency and robust stability despite uncertainties like time delays in communication channels and parameters of the slave manipulator and remote environment. The proposed method involves designing two local controllers - a slave controller at the remote site to track master commands, and a robust PID master controller at the local site to ensure transparency and stability. Simulation results will compare the proposed controller to a conventional multi-objective H2/H-infinity controller.

1) The document describes a study that uses an adaptive neuro-fuzzy inference system (ANFIS) algorithm to design a three-phase distance relay with fuzzy logic for fault detection and classification in overhead transmission lines.
2) The ANFIS generates a fuzzy system with two parts - the first detects faults by measuring voltage and current to calculate impedance, while the second determines fault location and type based on peak current values.
3) Simulation results showed the fuzzy logic distance relay successfully distinguished faults from disturbances, determined protection zones, and identified fault locations and types using data from a model of a 400kV transmission line in MATLAB/Simulink.

1) The document discusses the design and analysis of an H-infinity controller. H-infinity control guarantees robustness and good performance through high disturbance rejection.
2) It presents a simplified step-by-step procedure for designing an H-infinity controller for a given system using H-infinity loop shaping. This technique allows performance requirements to be incorporated into the design through the use of performance weights.
3) The generalized plant model is augmented with weight functions to shape the closed-loop response to meet design specifications such as uncertainty attenuation and required bandwidth. The H-infinity controller is then synthesized to minimize sensitivity and complementarity weights.

This document proposes using continuous wavelet transform (CWT) with a complex Morlet wavelet to detect low frequency oscillations in a power system. CWT is applied to signals measured from a two-area four-machine power system model. The results extract the frequency and damping of inter-area oscillations, which closely match those obtained from eigenvalue analysis. This demonstrates CWT as an effective technique for identifying low frequency oscillations in power systems.
Secure and Energy Savings Communication of Flying Ad Hoc Network for Rescue O...BRNSSPublicationHubI
This document summarizes a research article about developing a secure and energy-efficient routing protocol for Flying Ad Hoc Networks (FANETs) used in rescue operations. The protocol aims to address issues like lack of congestion control, reliability, and high energy consumption in FANETs. It proposes forming clusters of flying nodes based on distance and energy levels. It then calculates remaining energy of nodes to save resources. Finally, it establishes communication between clusters and a ground operation center using node velocity and location data. The goal is to enable secure and energy-efficient communication for coordinating rescue efforts using a rapidly deployable FANET.
1) The document describes the simulation of a differential relay for transformer protection using MATLAB/Simulink. A differential relay operates by comparing the current flowing into and out of a transformer and tripping the circuit breaker if there is a difference, indicating an internal fault.
2) The simulation models a power system including a transformer protected by a differential relay. Current transformers measure the primary and secondary currents which are compared in the relay.
3) Under normal operation the currents match and the relay does not trip, but internal faults create a difference that causes the relay to send a trip signal to the circuit breakers to isolate the fault. The simulation tests the relay under different fault conditions.
This document discusses the design and implementation of an oscillation controller for the driving mode of vibrational gyroscopes. It begins with background on vibrational gyroscopes and prior control approaches. It then presents a novel controller consisting of a PD controller combined with an online Extended State Observer. The ESO is used to estimate system states and model discrepancies. The PD controller drives the estimated discrepancies and output tracking error to zero. Simulation and hardware results validate the controller on a piezoelectric beam gyroscope. The controller is robust against gyroscope uncertainties and convergence of the ESO estimation error and stability of the closed-loop system are proven theoretically.

The document describes a proposed wavelet-fuzzy based multi-terminal transmission system protection scheme for accurate fault detection, classification, and location estimation in the presence of a STATCOM controller. The scheme uses wavelet transform to analyze current signals at terminals to detect and classify faults. A fuzzy inference system is then used to estimate the fault location. Digital simulations were performed on a four terminal transmission system with variations in fault distance, type, and inception angle. The results showed the scheme can accurately detect and classify faults within half a cycle and is suitable for multi-terminal systems with or without STATCOM compensation.

Moving Horizon Model Based Control in the Presence of Feedback NoiseEditor IJCATR
This paper studies the performance of networked control systems with a receding horizon controller. It is also assumed that there exists exogenous noise signal in feedback channel, modeled as a stochastic process. The impact of this noise on the closed-loop system performance is examined through both theoretical analysis and numerical experiments. An adaptive compensator is proposed to assist the original receding horizon controller. The performance of this solution is verified through simulation.
Aeolian vibrations of overhead transmission line bundled conductors during in...Power System Operation
Part B of this paper proposes a method for assessing
the performance of spacer-dampers on a quad-bundled
conductor using an existing system identification
algorithm and experimental modal data obtained from
Aeolian vibration measurements. To generate the
frequency response function (FRF) as a force input, a
shaker was used and attached at a certain distance via
a rigid link, and acceleration was measured at the free
span. To ensure that the data was not compromised, the
excitation technique used was first evaluated in different
configuration scenarios in part A of this paper. Three
different commercial spacer-dampers were used in this
investigation. One was placed at the mid-span and the
other two placed at different locations. The damping
performance was evaluated in terms of the main fatigue
indicator, i.e. the bending stress envelope of both clamp
edges at the spacer-damper and at the termination
clamp. A better performance configuration of bundled
conductors is the one that generates a bending stress

Power System State Estimation - A ReviewIDES Editor
This document provides a review of power system state estimation techniques. It discusses both static and dynamic state estimation algorithms. For static state estimation, it covers weighted least squares, decoupled, and robust estimation methods. Weighted least squares is commonly used but can have numerical instability issues. Decoupled state estimation approximates the gain matrix for faster computation. Robust estimation uses M-estimators and other techniques to handle outliers and bad data. Dynamic state estimation applies Kalman filtering, leapfrog algorithms, and other methods to continuously monitor system states over time.

This document summarizes a research paper that proposes using artificial intelligence techniques and FACTS controllers for reactive power planning in real-time power transmission systems. The paper formulates the reactive power planning problem and incorporates flexible AC transmission system (FACTS) devices like static VAR compensators (SVC), thyristor controlled series capacitors (TCSC), and unified power flow controllers (UPFC). Evolutionary algorithms like evolutionary programming (EP) and differential evolution (DE) are applied to find the optimal locations and settings of the FACTS controllers to minimize losses and costs. Simulation results on IEEE 30-bus and 72-bus Indian test systems show that UPFC performs best in reducing losses compared to SVC and TCSC.

Damping of power system oscillations with the help

(SVC)-based controllers are thoroughly investigated in this
paper. This study presents robust tuning of PID-PSS and
SVC-based controllers using Genetic Algorithms (GA) in
multi machine power systems by considering detailed model
of the generators (model 1.1). The effectiveness of FACTSbased
controllers in general and SVC-based controller in
particular depends upon their proper location. Modal
controllability and observability are used to locate SVC–based

Optimal Placement of DG for Loss Reduction and Voltage Sag Mitigation in Radi...IDES Editor
This paper presents the need to operate the power
system economically and with optimum levels of voltages has
further led to an increase in interest in Distributed
Generation. In order to reduce the power losses and to improve
the voltage in the distribution system, distributed generators
(DGs) are connected to load bus. To reduce the total power
losses in the system, the most important process is to identify
the proper location for fixing and sizing of DGs. It presents a
new methodology using a new population based meta heuristic
approach namely Artificial Bee Colony algorithm(ABC) for
the placement of Distributed Generators(DG) in the radial
distribution systems to reduce the real power losses and to
improve the voltage profile, voltage sag mitigation. The power
loss reduction is important factor for utility companies because
it is directly proportional to the company benefits in a
competitive electricity market, while reaching the better power
quality standards is too important as it has vital effect on
customer orientation. In this paper an ABC algorithm is
developed to gain these goals all together. In order to evaluate
sag mitigation capability of the proposed algorithm, voltage
in voltage sensitive buses is investigated. An existing 20KV
network has been chosen as test network and results are
compared with the proposed method in the radial distribution
system.
Line Losses in the 14-Bus Power System Network using UPFCIDES Editor
Controlling power flow in modern power systems
can be made more flexible by the use of recent developments
in power electronic and computing control technology. The
Unified Power Flow Controller (UPFC) is a Flexible AC
transmission system (FACTS) device that can control all the
three system variables namely line reactance, magnitude and
phase angle difference of voltage across the line. The UPFC
provides a promising means to control power flow in modern
power systems. Essentially the performance depends on proper
control setting achievable through a power flow analysis
program. This paper presents a reliable method to meet the
requirements by developing a Newton-Raphson based load
flow calculation through which control settings of UPFC can
be determined for the pre-specified power flow between the
lines. The proposed method keeps Newton-Raphson Load Flow
(NRLF) algorithm intact and needs (little modification in the
Jacobian matrix). A MATLAB program has been developed to
calculate the control settings of UPFC and the power flow
between the lines after the load flow is converged. Case studies
have been performed on IEEE 5-bus system and 14-bus system
to show that the proposed method is effective. These studies
indicate that the method maintains the basic NRLF properties
such as fast computational speed, high degree of accuracy and
good convergence rate.
Study of Structural Behaviour of Gravity Dam with Various Features of Gallery...IDES Editor
The size and shape of opening in dam causes the
stress concentration, it also causes the stress variation in the
rest of the dam cross section. The gravity method of the analysis
does not consider the size of opening and the elastic property
of dam material. Thus the objective of study is comprises of
the Finite Element Method which considers the size of
opening, elastic property of material, and stress distribution
because of geometric discontinuity in cross section of dam.
Stress concentration inside the dam increases with the opening
in dam which results in the failure of dam. Hence it is
necessary to analyses large opening inside the dam. By making
the percentage area of opening constant and varying size and
shape of opening the analysis is carried out. For this purpose
a section of Koyna Dam is considered. Dam is defined as a
plane strain element in FEM, based on geometry and loading
condition. Thus this available information specified our path
of approach to carry out 2D plane strain analysis. The results
obtained are then compared mutually to get most efficient
way of providing large opening in the gravity dam.
Assessing Uncertainty of Pushover Analysis to Geometric ModelingIDES Editor
Pushover Analysis a popular tool for seismic
performance evaluation of existing and new structures and is
nonlinear Static procedure where in monotonically increasing
loads are applied to the structure till the structure is unable
to resist the further load .During the analysis, whatever the
strength of concrete and steel is adopted for analysis of
structure may not be the same when real structure is
constructed and the pushover analysis results are very sensitive
to material model adopted, geometric model adopted, location
of plastic hinges and in general to procedure followed by the
analyzer. In this paper attempt has been made to assess
uncertainty in pushover analysis results by considering user
defined hinges and frame modeled as bare frame and frame
with slab modeled as rigid diaphragm and results compared
with experimental observations. Uncertain parameters
considered includes the strength of concrete, strength of steel
and cover to the reinforcement which are randomly generated
and incorporated into the analysis. The results are then
compared with experimental observations.

Selfish Node Isolation & Incentivation using Progressive ThresholdsIDES Editor
The problems associated with selfish nodes in
MANET are addressed by a collaborative watchdog approach
which reduces the detection time for selfish nodes thereby
improves the performance and accuracy of watchdogs[1]. In
the related works they make use of credit based systems, reputation
based mechanisms, pathrater and watchdog mechanism
to detect such selfish nodes. In this paper we follow an approach
of collaborative watchdog which reduces the detection
time for selfish nodes and also involves the removal of such
selfish nodes based on some progressively assessed thresholds.
The threshold gives the nodes a chance to stop misbehaving
before it is permanently deleted from the network.
The node passes through several isolation processes before it
is permanently removed. Another version of AODV protocol
is used here which allows the simulation of selfish nodes in
NS2 by adding or modifying log files in the protocol.
Various OSI Layer Attacks and Countermeasure to Enhance the Performance of WS...IDES Editor
Wireless sensor networks are networks having non
wired infrastructure and dynamic topology. In OSI model each
layer is prone to various attacks, which halts the performance
of a network .In this paper several attacks on four layers of
OSI model are discussed and security mechanism is described
to prevent attack in network layer i.e wormhole attack. In
Wormhole attack two or more malicious nodes makes a covert
channel which attracts the traffic towards itself by depicting a
low latency link and then start dropping and replaying packets
in the multi-path route. This paper proposes promiscuous mode
method to detect and isolate the malicious node during
wormhole attack by using Ad-hoc on demand distance vector
routing protocol (AODV) with omnidirectional antenna. The
methodology implemented notifies that the nodes which are
not participating in multi-path routing generates an alarm
message during delay and then detects and isolate the
malicious node from network. We also notice that not only
the same kind of attacks but also the same kind of
countermeasures can appear in multiple layer. For example,
misbehavior detection techniques can be applied to almost all
the layers we discussed.

and Military sectors The increasing popularity and usage of
wireless technology is creating a need for more secure wireless
Ad hoc networks. This paper aims researched and developed
a new protocol that prevents wormhole attacks on a ad hoc

they require highly specialized equipment not found on most

wormhole attacks as an Anti-worm protocol which is based on
responsive parameters, that does not require as a significant
amount of specialized equipment, trick clock synchronization,
no GPS dependencies.
Cloud Security and Data Integrity with Client Accountability FrameworkIDES Editor
This document summarizes a proposed cloud security and data integrity framework that provides client accountability. The framework aims to address issues like lack of user control over cloud data, need for data transparency and tracking, and ensuring data integrity. It proposes using JAR (Java Archive) files for data sharing due to benefits like portability. The framework incorporates client-side verification using MD5 hashing, digital signature-based authentication of JAR files, and use of HMAC to ensure data integrity. It also uses password-based encryption of log files to keep them tamper-proof. The framework is intended to provide both accountability and security for data sharing in cloud environments.
Genetic Algorithm based Layered Detection and Defense of HTTP BotnetIDES Editor
A System state in HTTP botnet uses HTTP protocol
for the creation of chain of Botnets thereby compromising
other systems. By using HTTP protocol and port number 80,
attacks can not only be hidden but also pass through the
firewall without being detected. The DPR based detection
leads to better analysis of botnet attacks [3]. However, it
provides only probabilistic detection of the attacker and also
time consuming and error prone. This paper proposes a Genetic
algorithm based layered approach for detecting as well as
preventing botnet attacks. The paper reviews p2p firewall
implementation which forms the basis of filtering.
Performance evaluation is done based on precision, F-value
and probability. Layered approach reduces the computation
and overall time requirement [7]. Genetic algorithm promises
a low false positive rate.
Enhancing Data Storage Security in Cloud Computing Through SteganographyIDES Editor
This document summarizes a research paper that proposes a method for enhancing data security in cloud computing through steganography. The method hides user data in digital images stored on cloud servers. When data needs to be accessed, it is extracted from the images. The document outlines the cloud architecture and security issues addressed. It then describes the proposed system architecture, security model, and data storage and retrieval process. Data is partitioned and hidden in multiple images to improve security. The goal is to prevent unauthorized access to user data stored on cloud servers.
The main tasks of a Wireless Sensor Network
(WSN) are data collection from its nodes and communication
of this data to the base station (BS). The protocols used for
communication among the WSN nodes and between the WSN
and the BS, must consider the resource constraints of nodes,
battery energy, computational capabilities and memory. The
WSN applications involve unattended operation of the network
over an extended period of time. In order to extend the lifetime
of a WSN, efficient routing protocols need to be adopted. The
proposed low power routing protocol based on tree-based
network structure reliably forwards the measured data towards
the BS using TDMA. An energy consumption analysis of the
WSN making use of this protocol is also carried out. It is
found that the network is energy efficient with an average
duty cycle of 0:7% for the WSN nodes. The OmNET++
simulation platform along with MiXiM framework is made
use of.
Permutation of Pixels within the Shares of Visual Cryptography using KBRP for...IDES Editor
The security of authentication of internet based
co-banking services should not be susceptible to high risks.
The passwords are highly vulnerable to virus attacks due to
the lack of high end embedding of security methods. In order
for the passwords to be more secure, people are generally
compelled to select jumbled up character based passwords
which are not only less memorable but are also equally prone
to insecurity. Multiple use of distributed shares has been
studied to solve the problem of authentication by algorithms
based on thresholding of pixels in image processing and visual
cryptography concepts where the subset of shares is considered
for the recovery of the original image for authentication using
correlation function[1][2].The main disadvantage in the above
study is the plain storage of shares and also one of the shares
is being supplied to the customer, which will lead to the
possibility of misuse by a third party. This paper proposes a
technique for scrambling of pixels by key based random
permutation (KBRP) within the shares before the
authentication has been attempted. Total number of shares to
be created is dependent on the multiplicity of ownership of
the account. By this method the problem of uncertainty among
the customers with regard to security, storage, retrieval of
holding of half of the shares is minimized.

Band Clustering for the Lossless Compression of AVIRIS Hyperspectral ImagesIDES Editor
Hyperspectral images can be efficiently compressed
through a linear predictive model, as for example the one
used in the SLSQ algorithm. In this paper we exploit this
predictive model on the AVIRIS images by individuating,
through an off-line approach, a common subset of bands, which
are not spectrally related with any other bands. These bands
are not useful as prediction reference for the SLSQ 3-D
predictive model and we need to encode them via other
prediction strategies which consider only spatial correlation.
We have obtained this subset by clustering the AVIRIS bands
via the clustering by compression approach. The main result
of this paper is the list of the bands, not related with the
others, for AVIRIS images. The clustering trees obtained for
AVIRIS and the relationship among bands they depict is also
an interesting starting point for future research.
Microelectronic Circuit Analogous to Hydrogen Bonding Network in Active Site ...IDES Editor
A microelectronic circuit of block-elements
functionally analogous to two hydrogen bonding networks is
investigated. The hydrogen bonding networks are extracted
from â-lactamase protein and are formed in its active site.
Each hydrogen bond of the network is described in equivalent
electrical circuit by three or four-terminal block-element.
Each block-element is coded in Matlab. Static and dynamic
analyses are performed. The resultant microelectronic circuit
analogous to the hydrogen bonding network operates as
current mirror, sine pulse source, triangular pulse source as
well as signal modulator.
Texture Unit based Monocular Real-world Scene Classification using SOM and KN...IDES Editor
In this paper a method is proposed to discriminate
real world scenes in to natural and manmade scenes of similar
depth. Global-roughness of a scene image varies as a function
of image-depth. Increase in image depth leads to increase in
roughness in manmade scenes; on the contrary natural scenes
exhibit smooth behavior at higher image depth. This particular
arrangement of pixels in scene structure can be well explained
by local texture information in a pixel and its neighborhood.
Our proposed method analyses local texture information of a
scene image using texture unit matrix. For final classification
we have used both supervised and unsupervised learning using
K-Nearest Neighbor classifier (KNN) and Self Organizing
Map (SOM) respectively. This technique is useful for online
classification due to very less computational complexity.
Cosa hanno in comune un mattoncino Lego e la backdoor XZ?Speck&Tech
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.
