Title: |
MULTI-LEVEL GROUP KEY MANAGEMENT TECHNIQUE FOR MULTICAST SECURITY IN MANET |
|
Author: |
R.VENNILA, V.DURAISAMY |
|
Abstract: |
In Mobile AdHoc Networks (MANETs), data transmission is speeded up by means of
multicasting. Though multicast transmission lessens overhead, collision and
congestion, it persuades new challenges towards security management. This
challenge must be conquered to bring better throughput of the network. In this
paper, we introduce a multi level group key management technique for multicast
security in MANET. Our technique works in a hierarchical model such that cluster
heads are prioritized over cluster members. The secure keys are generated using
one-way function chain. In addition to secure key management, the issue of
mobility is also handled. By simulation results, we prove the proficiency of our
proposed technique. Our secure key management technique incurs low overhead and
delay and significantly increases the throughput. |

Title: |
APPLICATION OF NON-TRADITIONAL METHOD FOR THE OPTIMIZATION OF FRICTION CLUTCH |
|
Author: |
FAISAL.S. HUSSAIN, M.K.SONPIMPLE |
|
Abstract: |
This paper describes the development of evolutionary algorithmfor the optimal
design of friction clutch.
Powerful evolutionary algorithm such as Genetic Algorithm (GA) is applied for
optimum design of friction clutch. The main objective function was to minimize
the axial force between clutch plate and pressure plate, using diameter ratio
and coefficient of friction as design variable and peripheral velocity as design
constraint.The analysis in the present paper is based on understanding the
relationship between diameter ratio and the design parameters like inner and
outer diameters and peripheral velocity in order to arrive at the optimum
design. It is shown that the dimensionless ratio of outer diameter to inner
diameter is the most fundamental parameter, controlling all the major designs as
well as performance parameters. The optimum design of clutch can be obtained,
satisfying the constraint on design, by controlling design variable. The results
of GA are compared with conventional optimization technique in order to satisfy
the main objective function to minimize the axial force between pressure plate
and clutch plate. |

A. BOUDHIR, Med.BOUHORMA, , Med.BENAHMED, S.Elbrak |
|
Abstract: |
As an emerging technology, WSN (Wireless Sensor Networks) composed from a large
number of small, low data rate and inexpensive node that communicate in order to
sense or control a physical phenomenon. WSN have a lot of applications like
disaster management, health, military and security, and enormously attracted the
community of researchers and has fueled the interest in sensor networks during
the past few years. Sensors are typically capable of wireless communication and
able to solve several problems in numerous domains. During the Hajj season, the
organizers faced a lot of problems related to the health of pilgrims and their
position in the area of El Hajj. At this time, the proposed works are focused on
the identification of pilgrims lost, using the implementation of RFID (Radio
Frequency IDentification). The latter solution, is as expensive equipment,
requires adding tags to pilgrims. Those tags are limited to read data from those
passives tags. Further work is limited only to the location of pilgrims.
However, the aim of this paper is to discuss and propose a system which allows
monitoring of pilgrims. Indeed, this allows, using a BSN (Body Sensor Network)
as a particular application of wireless sensor network, for the localization of
pilgrims lost and control, in real-time, the health status of those who fall
into critical situation with diseases that could threaten their health and life.
In this system, the agents in El Hajj, dispatched to several areas of Hajj and
have devices that install applications to monitor and locate pilgrims,
periodically, by reading sensors measurements in addition to their localization
with adequate and theoretical technique. This solution, present a model for an
area, and which can be duplicated for the full area of El hajj. It also
facilitates the intervention and localization, in real time, of pilgrims who are
away from their camps and to save their life. |

|
Author: |
C.SARAVANABHAVAN, R.M.S.PARVATHI |
|
Abstract: |
Data mining services require accurate input data for their results to be
meaningful, but privacy concerns may influence users to provide spurious
information. The problem of privacy-preserving data mining has numerous
applications in homeland security, medical database mining, and customer
transaction analysis. The main feature of the most PPDM algorithms is that they
usually modify the database through insertion of false information or through
the blocking of data values in order to hide sensitive information. In this
paper, we have incorporated the privacy preserving concept into the previously
developed weighted utility mining approach. In this, we have presented an
efficient algorithm for mining of privacy preserving high utility item sets by
considering the sensitive item sets. The algorithm comprise of three major steps
to attain the aim of our research includes, 1) Data sanitization, 2)
Construction of sensitive utility FP-tree and, 3) Mining of sensitive utility
item sets. The experimentation has carried out using real as well as the
synthetic dataset and the performance of the proposed algorithm is evaluated
with the aid of the evaluation metrics such as Miss cost and Database difference
ratio. |

Title: |
RECORD-TO-RECORD TRAVEL ALGORITHM FOR ATTRIBUTE REDUCTION IN ROUGH SET THEORY |
|
Author: |
MAJDI MAFARJA, SALWANI ABDULLAH |
|
Abstract: |
ttribute reduction is the process of selecting a minimal attribute subset from a
problem domain while retaining a suitably high accuracy in representing the
original attributes. In this work, we propose a new attribute reduction
algorithm called record-to-record travel (RRT) algorithm and employ a rough set
theory as a mathematical tool to evaluate the quality of the obtained solutions.
RRT is an optimization algorithm that is inspired from simulated annealing,
which depends on a single parameter called DEVIATION. Experimental results on 13
well known UCI datasets show that the proposed method, coded as RRTAR, is
comparable with other rough set-based attribute reduction methods available in
the literature. |

FUZZY INFERENCE SYSTEMS: STUDY CASE IN BALI INDONESIA |
|
Author: |
AGUS DHARMA, IMAM ROBANDI, MAURIDHI HERY PURNOMO |
|
Abstract: |
This paper presents the application of interval type-2 fuzzy inference systems
(IT2FIS) in short term load fore¬casting (STLF) on special days. This is a
continuation work of application interval type-2 fuzzy systems (IT2FSs) using
Karnik Mendel algorithm. Special days here mean local Balinese holidays such as
national and local culture-based public holidays, consecutive holidays, and days
preceding or following holidays. In general, the load values of special days
tend to decrease due to unlike load behavior of holidays com¬pare with ordinary
weekdays during the year. IT2FIS has recently been considerable attention for a
short term load forecasting problems due to their simple structure and high
identification performance. IT2FIS is the process of formulating and mapping
from a given input to an output using interval type-2 fuzzy logic. The Mamdani
interval type-2 fuzzy inference models and the design of interval type-2
membership functions and operators are implemented in the interval type-2 fuzzy
logic toolbox (IT2FLT). The method has been implemented on the historical peak
load data to solve the short term load forecasting during holiday for the Bali
electrical system, Indonesia. The results showed that the IT2FIS offer an
accu¬rate forecast of the peak load (in MW) on holidays, indicated by small mean
absolute percentage error (MAPE) less than 1.5% for the estimation task of the
year 2005 and 2006. More detail results and discussion are provided to show the
eminence of these methods handling the short term load forecasting task. |

Title: |
APPLIANCE CONTROL USING HUMAN DETECTION AND DISPARITY ESTIMATION |
|
Author: |
K.NARASIMHAN, M.SANKAR, D. RANJITH KUMAR, D.SRIRAM, U,S.RAVI KUMAR, S. NELSON |
|
Abstract: |
We here propose a novel method for detecting and locating the human presence for
controlling the power appliances in the subjected area. At the heart of our
Endeavour, we use an over-head camera to capture the scene inside the concerned
arena. From the scene we sample frames and process them to detect silhouette of
objects. We then use a codebook instance as a reference to filter out human
outline(s) to detect human. Their location in the room is traced using disparity
calculation and subsequent depth extraction. Once the location has been
estimated, the corresponding appliances can be operated accordingly for service.
A controller interfacing can be provided to achieve the above. This is done
using the serial communication technique with RS 232 . Presence of max 232 IC
guides the above. The serial communication is performed by specifying the port
and baud rate of use and burning the needed code to perform the task. |

OPTIMIZATION METHOD OF PILOT ALLOCATION FOR COOPERATIVE AMPLIFY-AND-FORWARD OFDM
SYSTEM |
|
Author: |
SUOPING LI, LITING YANG, JIN LI |
|
Abstract: |
Pilot-assisted channel estimation has been studied only in common cooperative AF
(Amplify-and-Forward) OFDM which has no feedback mechanism. In this paper, for
cooperative AF-OFDM system, we propose a feedback technique in which the pilot
allocation mechanism is adapted to the cooperative mobile channel. Then we show
how uniform pilots may no longer be optimal compared with our pilots. After
deducing the instantaneous system SNR is the function of the pilot allocation,
we optimize the pilot locations using optimization method at the destination
node. We examine the feedback overhead that is associated with our method and
make comparisons with the conventional uniform pilot allocation. To improve
system capacity, we suggest reduce the feedback information using K-means
clustering algorithm. Simulation results confirmed that the proposed
optimization method has an ideal performance gains and the algorithm of feedback
reduction can reduce the feedback information under the premise of ideal
performance. |

CLUSTERING TECHNIQUES IN FINANCIAL TIME SERIES DATA |
|
Author: |
V.ILANGO, R.SUBRAMANIAN, V.VASUDEVAN |
|
Abstract: |
The modern computing technology makes data gathering and storage easier. This
creates new range of problems and challenges for data analysis. Detection of
outliers in time series data has gained much attention in recent years. We
present a new approach based on clustering techniques for outlier. The
Expectation Maximization clusters (EM-Cluster) algorithm is used to find the
“optimal” parameters of the distributions that maximize the likelihood function.
Regression based outlier technique is used to detect influence point. The
analysis of outliers and influential points is an important step of the
regression diagnostics. Several indicators are used for identifying and
analyzing outliers. The proposed approach gave effective results within optimum
time and space when applied to synthetic data set. This paper investigates the
outliers, volatility clustering and risk-return trade-off in the Indian stock
markets NSE Nifty and BSE SENSEX. Engle's ARCH Test and AR (1)-EGARCH (p,
q)-in-Mean model were employed to examine the objective of the study. It
revealed that volatility is persistent and there is leverage effect in the
Indian stock markets. |

Abstract: |
The spatial variability of cultivated soil available phosphorus(P) contents is
the work foundation of adjusting measures for cultivated management, rationally
applying P fertilizer, minimizing P loss, decreasing non-point source pollution
of water. A case of Gaozhou City, we collected 664 soil samples in cultivate
horizon, then the characteristics of spatial variability, spatial distribution
pattern and is cause of county cultivated soil available phosphorus, used Radial
Basis Function Network optimized by Genetic Algorithm(GARBF for short) and
Geo-statistical methods and so on. The results showed that, while in the whole
region of Gaozhou City, the semi-variance structure was existed for spatial
variability of surface soil of cultivated land, and models best fit exponential
or spherical, there was structural spatial correlation in surface cultivated
soil available phosphorus in 5 sampling scales, which indicated that a poor
spatial correlation in content developed in large-block scale. The spatial
interpolation ability of GARBF neural network method was better than RBF neural
network prediction model based on several closest neighbors and Ordinary Kriging
method. The P application to cultivated soils in cropping systems in Gaozhou
City exceeded P offtake by crops. This surplus could lead to P accumulation in
cultivated soils, making them long-term diffuse sources of P loss water, which
formed a serious threat to the regional water environment. |

|
Author: |
HUNG-TENG CHANG |
|
Abstract: |
In recent years, the rising of customers’ awareness and spending power has led
to the growth of the customized products. The traditional enterprise-led
products are unable to meet the customers’ needs. Nowadays, the enterprises have
to put the emphasis on the customers’ preferences and products must be made to
satisfy the customers’ various needs.
In this research, we develop a set of Fuzzy Intention Product Design System. The
system is capable of breaking the restrictions of time and space. Through the
Fuzzy Analytic Hierarchy Process (FAHP), the triangular fuzzy numbers are put
into the Pairwise Comparison Matrix to prevent the fuzzy problems during the
process of conducting criteria measurement and judgment. By means of FAHP, the
AHP Exact Value will be substituted by the Interval Value. And the experts will
make strategic decisions with humanity when evaluating problems and give a
weight value to the measure factors.
The LCD screen support structure is connected with the Internet survey platform
and FAHP to construct the Fuzzy Intention Product Design Mechanism in this
study. The results shown in this paper are expected to be references to the
related study and the product designing.

Author: |
NING CHEN, XING XU |
|
Abstract: |
The traffic detecting result is always short of accuracy by different kinds of
individual sensors in urban China. A new information fusion approach is raised
in this paper to solve the issue, based on fuzzy rough set theory combining with
evidence theory. The method of attribute reduction has been improved based on
rough set and it could consider the relation of attributes during reduction
process. The essential probability function is obtained by the maximum fuzzy
likelihood function that helps to diminish the effect of subjective factor.
Furthermore, a new combination formula has been raised based on the Yager’s
formulas. It can reduce the negative effect on fusion accuracy caused by the
conflict of different evidences. Then, a new combination rule is given to
dissolve the confliction among the traffic evidence data collected by different
individual sensors. Finally, the experiment to fuse the traffic information from
an intersection in Hangzhou City showed that the proposed approach could obtain
a high accuracy. |

A new method of adaptive neural network decentralized control is designed for a
relevant large scale system with input saturation, it is not necessary for this
method to assume that relevant items satisfy the function upper bound of high
order or low order, cancel the constraint condition for known upper bound of the
unknown continuous function and controlled gain of the system. It is not
necessary to handle controlled gain with unknown directions by virtue of Nussbum
function, only using a neural network can simultaneously approximate unknown
function, unknown gains, and unknown relevant items. It can be known by using
the Lyapunov theoretical analysis that the designed method can guarantee the
control system to obtain overall situation stability, simulation results display
that the control method is valid and feasible. |

Abstract: |
Auction models are found efficient in managing resources allocation, which is a

approach is proposed, and its mechanism and related auction algorithm are
designed. In our approach, the grid trading service, i.e., an intelligent
entity, uses this auction algorithm to estimate the resource user’s satisfaction
degree and help the resource providers to update their multi-attribute bidding
strategies in the next round. Numerical simulating experiments show that our
model can satisfy a resource user’s quality demand on multiple attributes, and
have better performance in user utility. The results also illustrate that
revealing the resource user's preferences increases allocated efficiency. |

ANALYSIS AND APPLICATION OF RIGID BODY DYNAMICS THEORY IN BILLIARDS SPORT |
|
Author: |
JIANFENG WU, LIN GUO |
|
Abstract: |
This article conducts mechanical analysis of billiards and studies its motion
laws. For convenience, only situations as the ball arm bats the billiards in the
horizontal direction are considered. Besides, collision between one billiard
ball and another or between a ball and the “KEXING” is assumed to be elastic.
The following cases are quantitatively analyzed based on the rigid body dynamics
theory: the “Safety zone” to prevent the slider and rod drop when the ball arm
hits the cur ball; the principle and function of fixed rod ball, push rod ball,
tie rod ball and side spinning ball; the relative motion between the white
billiard and the mesa; the Kinematic relation when the white billiard collides
with the aim billiard; the Kinematic relation when the white billiard collides
with the “KEXING”. By analyzing the dynamic characteristics of billiards sport,
this article provides guidance for players with a scientific batting and helps
to correct the misunderstanding in billiards theory. Except for providing
theoretical material for this popular indoor recreation project, this study can
also offer a mathematical model of billiards for the future designers and
developers of billiards games to make it closer to the real motion. |

Author: |
ZHENYU TANG, WEI YANG |
|
Abstract: |
There’re certain deficiencies in the existing studies on performance appraisal
pattern for college PE teachers, which are embodied in the following: the
indicators of performance appraisal lack pertinence; the quantitative studies on
the indicators of performance appraisal are insufficient; the results of the
appraisal are short of necessary feedback and reasonable application. This paper
conducts research on performance appraisal pattern for college PE teachers. The
result reveals that three dimensions and ten specific indicators are included in
the performance appraisal pattern for college PE teachers, which are: teachers’
demonstrating performance, including four items: industriousness and dedication,
professional ethics, model standard as well as working attitude; teaching
ability performance, containing: teaching efficiency, professional competence
and management ability; teaching improvement performance, consisting of:
learning ability, teaching and research achievement and communication and
cooperation. Meanwhile, according to the practical application, AHP is used for
weight calculation of all the indicators in the pattern. The pattern overcomes
the problems that exist in other approaches like excessive subjectivity, obscure
boundary between qualitative index and quantitative index, and chaotic weight. |

AN ENVIRONMENT FOR MODELING AND TESTING STOCHASTIC SYSTEMS |

MOKDAD AROUS, KENZA BOUAROUDJ, DJAMEL-EDDINE SAÏDOUNI |
|
Abstract: |
This paper addresses a formal testing based on Stochastic Refusals Graphs (SRG)
in order to test stochastic systems. As a semantic model for these systems, we
chose the MLSTS models. MLSTS (for Maximality-based Labeled Stochastic
Transition System) is a new semantic model for characterizing the stochastic
temporal properties of concurrent systems, under the assumption of arbitrarily
distributed (i.e. non-Markovian) durations of actions [14]. MLSTS can be easily
described by using a Stochastic Process Algebra (SPA) language, namely S-LOTOS
[15]. So, a method for testing stochastic system modeled by MLSTS is proposed
[23]. We present here a tool for Modeling and testing Stochastic Systems, called
MoVeS, which allows generating automatically MLSTS models from S-LOTOS
specifications, then constructing automatically Refusal Graphs and Canonical
Tester. |

Abstract: |
The present paper demonstrated the different emotional responses between males
and females triggered by sportswear styling, using SAM model and ERPs instrument
to examine the interactions of human psychological emotions and their brainwave
changes which indicate physiological activity of the central nervous system. The
main purpose of this paper was to use brain imaging technology to recognize the
differences of “inner” emotions between males and females from brain wave
signals, and to examine the interactions of human’s psychological emotion
dimensions and psychophysiological responses. Results indicated that males and
females had similarity and inconsistency for the emotional response of different
styling of clothing. The advantage over traditional methods of measuring emotion
evoked by clothing, like self-reports is that they leave out the psychological
and physiological biases of Emotions. The study’s findings should provide
valuable information and reference to fashion designers, consumers and clothing
manufacturers for future product design and development. |

Abstract: |
In recent years, with the extensive application of video surveillance system in
police’s criminal investigation, video investigation technology is playing a
more and more important role in detection of cases. Key characters in case
spots, such as criminal suspects and witnesses are often targets that attract
most attentions. Therefore, face image become the key clue of a case. While in
actual surveillance, due to distance and limitation of equipment, definition of
most face images is of low-quality. Face super-resolution technology can make
use of information in face sample database to restore high definition face
image, which can effectively enhance definition of face images in surveillance

A METHOD FOR FINGERPRINT MATCHING USING INVARIANT MOMENT |
|
Author: |
DONGFENG XU, YAN CHEN |
|
Abstract: |
A method for fingerprint matching using invariant moment featuresis proposed.
The fingerprint image is first preprocessed to enhance the original image by the
Short Time Fourier Transform (STFT) analysis. Then, a set of seven invariant
moment features is extracted to represent the fingerprint image from a cirque of
Interest (COI) based on the reference point of the enhanced fingerprint image.
The reference point is determined by the complex filters method. Finally, a Back
Propagation Neural Network (BPNN) (moment of inertia) is trained with the
features for matching. Experimental results show the proposed method has better
performance with higher accuracy and faster speed comparing to the traditional
Gabor feature-based fingerCode method. |

|
Author: |
WANG QIJI |
|
Abstract: |
The main method to improve the invest benefit of photovoltaic electricity
generation system on solar cabin surface is to increase the electricity
generation capacity and decrease the building cost. To get the largest total
electricity generation of cabin and the least unit electricity generation cost
as the goal, the paper sets up a multi-objective programming model. Due to the
limited conditions, complex constraint function, large solution space dimension,
it is difficult to get the analytic solution. The time-consuming of traditional
recursive algorithm is growing in exponential series with recursion depth, which
is hard to find the optimal solution in the effective time. To solve this
problem, the paper is inspired by "selection index", uses heuristic algorithm,
fully considers the optimization target in the process of selection and
arrangement, and finally get the optimization solution including the factors of
total electricity generation, cost, and benefit and so on in a short time. A
laying scheme of photovoltaic cell on solar cabin surface that meets the
preconcerted target is obtained, and an experiment with true data shows that it
is correct. |

CLOUD |
|
Author: |
BINGCAI LV, SHIDONG ZHANG, YULIANG SHI |
|
Abstract: |
Multi-tenant sharing model is the way to maximize the economic benefit of the
resources in the cloud. However, the higher the sharing scales of the nodes, the
heavier the load they bore, thus decreasing tenants’ user experience. In this
paper, we proposed a Pub/Sub-based multi-tenant process resource management
framework, which appropriately defusing the peak-load situation and minimizing
every tenant’s response time as well as guaranteeing the highest sharing rate.
Based on the framework, a load balance strategy that dual optimize users’
experience from both deployment and runtime is presented. During the deployment
phase, dynamic replica placement policy helps to decide the best placement
strategy for the business process unit; optimal process node selection policy is
responsible for choosing the optimal process node for every tenant at runtime.
Experimental results show the efficiency of this mechanism. |

JIANJUN SUN, LIANFEN HUANG, YUE HUANG |
|
Abstract: |
Retinal vascular imaging system offers a noninvasive research tool to probe the
pathophysiology of the microvasculature. Retinal vascular skeleton extraction
from fundus images is an essential step to analyze the retinal vascular
branching pattern. An improved tracing based approach is presented in this work
to extract the centerlines for retinal vasculatures in the fundus images
automatically. Compared with existing work, the major contribution of the
proposed algorithm is that it incorporates geometrical information and intensity
distribution of the retinal vessels to define a new tracking updated direction
scheme. In addition, the scale value in defining Hessian matrix is also dynamic
and self-adaptive, as well as the size of searching window in identifying the
boundary positions during the tracing process. Experiments results and
validations have demonstrated that proposed approach has satisfied accuracy in
vessel skeleton tracking. |

YONGZHEN KE, WEIDONG MIN, XIUPING DU, ZHENWEI CHEN |
|
Abstract: |
With the development of computer graphic techniques and smaller visual
difference between photographic images (PG) and computer graphics (CG), splicing
of computer graphics and photographic is becoming more common, which causes the
need for automatically distinguishing computer generated images from real
photographs. Based on several visual features that derived from color, texture
and shape feature, using posterior probability support vector machine (PPSVM),
this paper presents a method for classification of photographic image and
computer generated images, and detection of local forgery composite of them.
These features are obtained from 800 computer generated images and 800
photographs, and used to train and test the image samples with the PPSVM. The
PPSVM can calculate the probability of image belonging to photographic images or
computer generated images. We can achieve the result of classification by
setting a threshold of probability. The classification accuracies for color,
texture and shape features are 76.75%, 85.25% and 69% respectively. The accuracy
is improved to 89.375% with combined color, texture and shape features. The
proposed classification method is used to detect the local forgeries composite
of the CG elements in photographic, and vice visa. Experimental results show
that the proposed method is efficient with good detection rate of local
forgeries composite of the PG and the CG. It also possess low dimensional
features and low time complexity. |

INTEGER DCT-BASED SELF-RECOVERY WATERMARKING ALGORITHM |
|
Author: |
HONGXIA WANG, QIUCHEN MEN |
|
Abstract: |
To address the problems of the inferior recovery and lower security in existing
self-recovery fragile watermarking algorithms, this paper presents a secure
self-recovery fragile watermarking scheme based on integer DCT. In the proposed
algorithm, first, the original image is divided into 4×4 blocks, then the
recovery watermark of each 4×4 block is generated by the image block’s integer
DCT coefficients, after that, the secure Hash function with three keys is
performed on each 4×4 block to get the corresponding offset block, and finally
the recovery watermark of each block is embedded into its corresponding offset
block under the control of three keys. Thus, the adversary is difficult to
counterfeit the watermark information when he/her tampers with image content.
Moreover, the offset key space is large enough . Because the forward and inverse
integer DCT can contribute an accurate data match, the recovery of tampered area
will be more accurate. Compared with current self-recovery fragile watermarking
algorithms commonly using DCT technique or encoded pixel values of an image
block, the proposed scheme not only resolves the tamper detection problem, but
also improves the recovery image quality and system security. |

Abstract: |
This paper briefly discussed the principle of the linear constraints minimum
variance (LCMV) algorithm and the least mean square (LMS) algorithm on the basis
of the construction of an uniform circular antenna array. Then it compared the
parameters of the two, such as signal-to-noise ratio, bit error rate, the
average error, convergence rate, and so on, and then it was simulated by MATLAB.
The simulation results showed that performances of LCMV algorithm were a little
bit worse than LMS algorithm when interference was relatively strong, but much
better than LMS when SNR was above 0dB. At last, we found out the appropriate
algorithm for each environment, and proposed the improvement measures. |

Abstract: |
A novel approach is proposed in this paper for personnel and vehicle iterative
evacuation optimization to tackle crowd evacuation problem in emergency. The
paper analyzes the mechanism to coordinate people flow evacuation with traffic
stream evacuation, and explores optimization model from a personnel and vehicle
coordination evacuation perspective. The evacuation is classified as two
categories, namely evacuation with intervention and evacuation without
intervention, which depends on whether intervention can be applied to path
selection for evacuees. Scheduling scheme of evacuation vehicles is derived from
improved ant colony algorithm, and then we integrate personnel evacuation
simulation with micro traffic simulation system based on distributed
collaborative simulation platform. Finally the optimal scheduling solution of
system is searched out through constantly modifying evacuation plan by improved
genetic algorithm. |

Abstract: |
A key agreement scheme for large dynamic multicast group systems has been
designed to cope with such applications including pay-tv, teleconferencing,
collaborative work, online games, and so forth. To avoid heavy loads and
unauthorized accesses to the system, it is necessary to construct an efficient
and secure scheme. Some recently released schemes have tree-based underlying
structures. The efficiency of these tree-based schemes is closely associated
with the height of the underlying tree. In this paper, we propose a secure and
efficient key agreement scheme for large groups that adopts a quad tree as the
underlying key tree. |

Abstract: |
To get land cover information of study city area, and according to the spectral
feather of the wanted classes including water, vegetation, impervious surface,
and soil at LANDSAT-TM remote sensing image, we used a method that using three
indexes including normalized difference vegetation index, modify normalized
difference water index, and ratio impervious surface index to extract the
thematic information separately. Firstly, we use the indexes to calculate the
image. Then, we choose threshold for the three thematic layers and did
binarization for them too. In this step, we defined RISI according to the
spectral feature and found the RISI cannot extract the impervious surface
correctly, water information was also extracted. So, we calculated the RISI
first, and then, used it to subtract MNDWI to get the impervious surface
information and, a better result was gotten. Finally, we stack the three layers
together and gave them the false color and, cause soil had very low value in all
three indexes layers, the map including water, vegetation, impervious surface
and soil was gotten together in one image, and it is effective to get them just
by color difference. With taking the high resolution image as reference, the
totally accuracy it can get was 91.3%, and the KAPPA was 0.892. |
