BEAM SPOT OF Q-SWITCHED ND:YAG LASER BASED ON RASTER GRAPHIC |
by A.R. Tamuri, N. Bidin & Y.M. Daud |
Abstract |
The quality
of beam produced by a Q-switched Nd:YAG laser was investigated. A photographic technique
associated with image processing system was utilized to determine the beam quality.
The invisible light was detected using burn paper at various operation voltages
of flashlamp driver in the range of 450 V to 900 V. The permanent record of the
beam spots were made via a scanner and analyze using raster graphic or bitmap from
a Matrox Inspector version 2.1 software. The line profile each of the beam spot
produced an absorption spectrum. The amplitude of the spectrum indicates the depthness
of the hole created after laser interaction with photographic paper. Meanwhile the
width shows the beam size as well as the surface roughness. Thus the beam quality
is illustrated by the depthness and the flatness of the beam spot. The flatter the
surface the more uniform the laser beam distribution and the deeper the hole the
more energetic the laser beam interacted with burn paper.

LUMINESCENCE PROPERTIES OF GAMMA IRRADIATED AMPHIBOLITES AND ß-ANHYDRITE RELEVANT TO DOSIMETRY |
by Obed R.I, Olatunji A, Fasasi M.K, Dejene F.B & Adebiyi A.A
|
Abstract |
The thermoluminescence
(TL) characteristics of amphibolites and β-anhydrite have been investigated after
gamma-ray irradiation. Both materials presented glow curves as a consequence of
their trap system. The amphibolites have two peaks at low doses which convoluted
to one peak at high doses. The β-anhydrite also has two main peaks that are prominent
at high doses. Linearity index analysis showed that the amphibolite is supralinear
while the β-anhydrite is either sublinear or supralinear depending on the dosimetric
peak used. The amphibolites faded by 35% per month, while the β-anhydrite faded
by 67% in a month. The two materials studied presented different TL properties.

BUCKLING RESTRAINED BRACES FOR VIBRATION CONTROL OF BUILDING STRUCTURE |
by W.N. Deulkar, C.D. Modhera & H.S. Patil |
Abstract |
This paper presents
the study of Buckling Restrained Braces (BRB), its analysis, design, modeling and
its application in steel building frame. A brief review of work done on BRB is presented
and nonlinear time history analysis of 5-story 2D frame
is carried using software,
SAP 2000 under El Centro earthquake. The response parameters used to evaluate structural
performance are natural time period, story displacement, interstory drift, story
shear and axial forces. The parameters, length and area of yielding core for modeling
the correct behavior BRB are evaluated. Five different types of BRB configuration
are studied. It is observed that BRB can be modeled by keeping the area of central
core equal to or less than half of end offset area and length of yielding central
core equal to 1/3 of total length of brace.
Based on the study, new brace configuration
is proposed which controls joint displacement over the unbraced and BRB configurations
studied.

PRESENTATION AND VALIDATION OF REMOTE SENSING OCEAN WAVE DATA |
by Omar Yaakob, Norazimar Zainudin, Yahya Samian, Adi Maimun, Abdul Malik & Robiahtul Adawiah Palaraman |
Abstract |
The use of satellite wave altimetry has increased the possibility of getting better temporal and spatial coverage of wave data collection. Whilst the method to obtain
wave heights is well established, such is not the case with methods of derivations
of wave periods. This study presents
a review of four available methods to derive wave periods and describes the implementation of such methods to obtain Malaysian ocean waves joint probabilities of wave heights
and wave periods data from TOPEX/Poseidon satellite altimetry.
Data is presented in formats similar to the commonly used Global Wave Statistics.
Comparisons are made with measured data from a petroleum company offshore platform.
Results indicate that two methods produced almost identical wave periods data to
the measured data.

TRUNCATED ZERO INFLATED BINOMIAL CONTROL CHART FOR MONITORING RARE HEALTH EVENTS |
by Amir Afshin Fatahi, Rassoul Noorossana, Pershang Dokouhaki & Massoud Babakhani |
Abstract |
Development of miscellaneous statistical
methods for monitoring rare health events shows significance of the matter in health
engineering domain. Rare health events, as attribute quality characteristics can
not be monitored by traditional Shewhart based np charts since overdispersion occurs.
One relatively new approach to the problem is the use of control charts based on
zero inflation in a binomial (ZIB) distribution. In this distribution it is assumed
that random shocks occur with some probability, and upon the occurrence of such
random shocks, health event failures can be found, such that the number of failures
in each sampling subgroup follows a binomial distribution.
This paper develops a truncated ZIB control chart (TZIB) applying probability limits
in lieu of Shewhart based control limits for monitoring ZIB distributed observations.
As the most prevalent criteria, average run length approach is used to evaluate
the performance of the proposed chart. The applicability of TZIB control chart in
phase I and phase II control charting is also investigated by a real case study,
using the number of patients who go under surgery in a hospital and contract a wound
infection. Results are compared with np chart as an inefficient control chart for
our case study.

DISTRIBUTED DATA MINING AND AGENT MINING INTERACTION AND INTEGRATION: A NOVEL APPROACHE |
by Vuda Sreenivasa Rao, S. Vidyavathi & G.Ramaswamy |
Abstract |
In recent years,
more and more researchers have been involved
in research on both agent technology
and distributed data mining. A clear disciplinary effort has been activated toward
removing the boundary between them,
that is the interaction and integration between agent technology and distributed
data mining. We refer this to agent mining as a new area. The marriage of
agents and distributed data mining is driven by challenges faced by both communities,
and the need of developing more advanced intelligence, information processing and
systems. In this paper presents an overall picture of agent mining from the perspective of positioning it as an emerging area. We summarize the main distributed data mining,
driving forces, disciplinary framework, applications, and trends and directions,
data mining-driven agents, and mutual issues in agent mining. Arguably, we draw
the following conclusions: (1) agent mining emerges as a new area in the scientific
family, (2) both agent technology and distributed data mining can greatly benefit
from agent mining, (3) it is very promising to result in additional advancement
in intelligent information processing and systems. However, as a new open area,
there are many issues waiting for research and development from theoretical, technological
and practical perspectives.

EFFECT OF ANNEALING ON MORPHOLOGY OF THERMOTROPIC LIQUID CRYSTALLINE POLYESTERS |
by Malabika Talukdar |
Abstract |
Liquid crystal
polymers with semiflexible polymer backbone exhibit crystalline order despite of
some defects in crystal packing. Isothermal heat treatment of the polymers below
and above their liquid crystalline temperatures is expected to provide the necessary
energy and time for the molecular chains to overcome the defects in crystal packing
and to be arranged in a more perfect crystal lattice. A number of liquid crystalline
polyesters, possessing both rigid mesogenic groups and flexible aliphatic spacers
in the polymer backbone, have been considered for this experiment and were annealed
at different temperatures. An improvement in molecular and crystal structure of
the polyesters has been observed and the results of such experiment using FTIR spectroscopy,
optical microscopy and wide angle X-ray diffraction of the sample before and after
annealing are presented here.

EVALUATION OF RELIABILITY FACTORS USING BOOLEAN FUNCTION TECHNIQUE IN MILK POWDER MANUFACTURING PLANT |
by Shikha Bansal, S.C. Agarwal & Kuldeep Sharma |
Abstract |
For systems of multistate elements, the problem of developing
Boolean reliability models was considered on the basis of logic, algebra of groups
of incompatible events and classical logic and probabilistic method. The objective
of this paper is to compute the terminal reliability of milk powder manufacturer
plant based on a minimizing Boolean expression technique. Milk powder consists of
four subsystems A, B, C, D viz; storage, hot plates, evaporator, dryer, arranged
in series respectively. Subsystem A and C has two units in standby with perfect
switching. Subsystem B has two units in parallel redundancy and subsystem D has
one unit. The failure rate is exponentially distributed. The reliability and MTTF
have been evaluated. We demonstrate the use our technique by means of examples and
present numerical results to show the effects of mission phases on the system reliability.

by F.B. Abdullahi, M.M. Lawal & J.O. Agushika |
Abstract |
This study focuses on the development of a web-based GIS
for public healthcare system. The development of this system is motivated to provide opportunities for the healthcare workers
to gain access to vital information that can aid him/her in the location of viable
hospitals for the patients to fully enjoy available enhanced healthcare services.
Currently, three major problems still exist in the healthcare geographic
applications. This relate to health mapping methods, reusability of health applications,
and interoperability issues. To handle these problems, we design a Web-based GIS
for Public healthcare system to support health data sharing and representation.
The developed model makes it possible to locate the nearest hospitals as well as
the services they rendered. This study explored the use of open source software, web
server is Apache extended with support for PHP, MySQL and ARCGIS 9.2. Authentication is built into the
system as security pass mark for accessing information in the data base.
