Abstract: The research is to minimize environmental damage
pertinent to maritime activities about the operation of lighter boat
anchorage and its tugboat. The guidance on upgrading current
harbor service and infrastructure has been provided to Kho Sichang
Municpality. This will involve a study of the maritime logistics of
the water area under jurisdiction of the Sichang island Municipality
and possible recommendations may involve charging taxes,
regulations and fees. With implementing these recommendations will
help in protection of the marine environment and in increasing
operator functionality. Additionally, our recommendation is to
generate a consistent revenue stream to the municipality. The action
items contained in this research are feasible and effective, the success
of these initiatives are heavily dependent upon successful promotion
and enforcement. Promoting new rules and regulations effectively
and peacefully can be done through theories and techniques used in
the psychology of persuasion. In order to assure compliance with the
regulations, the municipality must maintain stringent patrols and
fines for violators. In order to become success, the Municipality
must preserve a consistent, transparent and significant enforcement
system. Considering potential opportunities outside of the current
state of the municipality, the authors recommend that Koh Sichang be
given additional jurisdiction to capture value from the master vessels,
as well as to confront the more significant environmental challenges
these vessels pose. Finally, the authors recommend that the Port of
Koh Sichang Island obtain a free port status in order to increase
economic viability and overall sustainability.
Abstract: In order to develop any strategy, it is essential to first
identify opportunities, threats, weak and strong points. Assessment of
technology level provides the possibility of concentrating on weak
and strong points. The results of technology assessment have a direct
effect on decision making process in the field of technology transfer
or expansion of internal research capabilities so it has a critical role
in technology management. This paper presents a conceptual model
to analyze the technology capability of a company as a whole and in
four main aspects of technology. This model was tested on 10
automotive parts manufacturers in IRAN. Using this model,
capability level of manufacturers was investigated in four fields of
managing aspects, hard aspects, human aspects, and information and
knowledge aspects. Results show that these firms concentrate on hard
aspect of technology while others aspects are poor and need to be
supported more. So this industry should develop other aspects of
technology as well as hard aspect to have effective and efficient use
of its technology. These paper findings are useful for the technology
planning and management in automotive part manufactures in IRAN
and other Industries which are technology followers and transport
their needed technologies.
Abstract: High redundancy and strong uncertainty are two main characteristics for underwater robotic manipulators with unlimited workspace and mobility, but they also make the motion planning and control difficult and complex. In order to setup the groundwork for the research on control schemes, the mathematical representation is built by using the Denavit-Hartenberg (D-H) method [9]&[12]; in addition to the geometry of the manipulator which was studied for establishing the direct and inverse kinematics. Then, the dynamic model is developed and used by employing the Lagrange theorem. Furthermore, derivation and computer simulation is accomplished using the MATLAB environment. The result obtained is compared with mechanical system dynamics analysis software, ADAMS. In addition, the creation of intelligent artificial skin using Interlink Force Sensing ResistorTM technology is presented as groundwork for future work
Abstract: Sensor Network are emerging as a new tool for
important application in diverse fields like military surveillance,
habitat monitoring, weather, home electrical appliances and others.
Technically, sensor network nodes are limited in respect to energy
supply, computational capacity and communication bandwidth. In
order to prolong the lifetime of the sensor nodes, designing efficient
routing protocol is very critical. In this paper, we illustrate the
existing routing protocol for wireless sensor network using data
centric approach and present performance analysis of these protocols.
The paper focuses in the performance analysis of specific protocol
namely Directed Diffusion and SPIN. This analysis reveals that the
energy usage is important features which need to be taken into
consideration while designing routing protocol for wireless sensor
network.
Abstract: Complex assemblies of interacting proteins carry out
most of the interesting jobs in a cell, such as metabolism, DNA
synthesis, mitosis and cell division. These physiological properties
play out as a subtle molecular dance, choreographed by underlying
regulatory networks that control the activities of cyclin-dependent
kinases (CDK). The network can be modeled by a set of nonlinear
differential equations and its behavior predicted by numerical
simulation. In this paper, an innovative approach has been proposed
that uses genetic algorithms to mine a set of behavior data output by
a biological system in order to determine the kinetic parameters of
the system. In our approach, the machine learning method is
integrated with the framework of existent biological information in a
wiring diagram so that its findings are expressed in a form of system
dynamic behavior. By numerical simulations it has been illustrated
that the model is consistent with experiments and successfully shown
that such application of genetic algorithms will highly improve the
performance of mathematical model of the cell division cycle to
simulate such a complicated bio-system.
Abstract: Image clustering is a process of grouping images
based on their similarity. The image clustering usually uses the color
component, texture, edge, shape, or mixture of two components, etc.
This research aims to explore image clustering using color
composition. In order to complete this image clustering, three main
components should be considered, which are color space, image
representation (feature extraction), and clustering method itself. We
aim to explore which composition of these factors will produce the
best clustering results by combining various techniques from the
three components. The color spaces use RGB, HSV, and L*a*b*
method. The image representations use Histogram and Gaussian
Mixture Model (GMM), whereas the clustering methods use KMeans
and Agglomerative Hierarchical Clustering algorithm. The
results of the experiment show that GMM representation is better
combined with RGB and L*a*b* color space, whereas Histogram is
better combined with HSV. The experiments also show that K-Means
is better than Agglomerative Hierarchical for images clustering.
Abstract: Gliding during night without electric power is an efficient method to enhance endurance performance of solar aircrafts. The properties of maximum gliding endurance path are studied in this paper. The problem is formulated as an optimization problem about maximum endurance can be sustained by certain potential energy storage with dynamic equations and aerodynamic parameter constrains. The optimal gliding path is generated based on gauss pseudo-spectral method. In order to analyse relationship between altitude, velocity of solar UAVs and its endurance performance, the lift coefficient in interval of [0.4, 1.2] and flight envelopes between 0~30km are investigated. Results show that broad range of lift coefficient can improve solar aircrafts- long endurance performance, and it is possible for a solar aircraft to achieve the aim of long endurance during whole night just by potential energy storage.
Abstract: We study different types of aggregation operators and
the decision making process with minimization of regret. We analyze
the original work developed by Savage and the recent work
developed by Yager that generalizes the MMR method creating a
parameterized family of minimal regret methods by using the ordered
weighted averaging (OWA) operator. We suggest a new method that
uses different types of geometric operators such as the weighted
geometric mean or the ordered weighted geometric operator (OWG)
to generalize the MMR method obtaining a new parameterized family
of minimal regret methods. The main result obtained in this method
is that it allows to aggregate negative numbers in the OWG operator.
Finally, we give an illustrative example.
Abstract: Fishbone of Nile Tilapia (Tilapia nilotica), waste from the frozen Nile Tilapia fillet factory, is one of calcium sources. In order to increase fish bone powder value, this study aimed to investigate the effect of Tilapia bone flour (TBF) addition (5, 10, 15% by flour weight) on cooking quality, texture and sensory attributes of noodles. The results indicated that tensile strength, color value (a*) and water absorption of noodles significantly decreased (p£0.05) as the levels of TBF increased from 0-15%. While cooking loss, cooking time and color values (L* and b*) of noodles significantly increased (p£0.05). Sensory evaluation indicated that noodles with 5% TBF received the highest overall acceptability score.
Abstract: Promoting critical thinking (CT) in an educational
setting has been appraised in order to enhance learning and
intellectual skills. In this study, a pedagogical course in a vocational
teacher education program in Turkey was designed by integrating CT
skill-based strategies/activities into the course content and CT skills
were means leading to intended course objectives. The purpose of the
study was to evaluate the importance of the course objectives, the
attainment of the objectives, and the effectiveness of teachinglearning
strategies/activities from prospective teachers- points of
view. The results revealed that although the students mostly
considered the course objectives important, they did not feel
competent in the attainment of all objectives especially in those
related to the main topic of Learning and those requiring higher order
thinking skills. On the other hand, the students considered the course
activities effective for learning and for the development of thinking
skills, especially, in interpreting, comparing, questioning,
contrasting, and forming relationships.
Abstract: The demand of hydrocarbons has increased the
construction of pipelines and the protection of the physical and
mechanical integrity of the already existing infrastructure. Corrosion
is the main reason of failures in the pipeline and it is mostly produced
by acid (HCOOCH3). In this basis, a CFD code was used, in order to
study the corrosion of internal wall of hydrocarbons pipeline. In this
situation, the corrosion phenomenon shows a growing deposit, which
causes defect damages (welding or fabrication) at diverse positions
along the pipeline. The solution of the pipeline corrosion is based on
the diminution of the Naphthenic acid.
Abstract: Optimal design of structure has a main role in reduction of material usage which leads to deduction in the final cost of construction projects. Evolutionary approaches are found to be more successful techniques for solving size and shape structural optimization problem since it uses a stochastic random search instead of a gradient search. By reviewing the recent literature works the problem found was the optimization of weight. A new meta-heuristic algorithm called as Cuckoo Search (CS) Algorithm has used for the optimization of the total weight of the truss structures. This paper has used set of 10 bars and 25 bars trusses for the testing purpose. The main objective of this work is to reduce the number of iterations, weight and the total time consumption. In order to demonstrate the effectiveness of the present method, minimum weight design of truss structures is performed and the results of the CS are compared with other algorithms.
Abstract: Human Resource (HR) applications can be used to
provide fair and consistent decisions, and to improve the
effectiveness of decision making processes. Besides that, among
the challenge for HR professionals is to manage organization
talents, especially to ensure the right person for the right job at the
right time. For that reason, in this article, we attempt to describe
the potential to implement one of the talent management tasks i.e.
identifying existing talent by predicting their performance as one of
HR application for talent management. This study suggests the
potential HR system architecture for talent forecasting by using
past experience knowledge known as Knowledge Discovery in
Database (KDD) or Data Mining. This article consists of three
main parts; the first part deals with the overview of HR
applications, the prediction techniques and application, the general
view of Data mining and the basic concept of talent management
in HRM. The second part is to understand the use of Data Mining
technique in order to solve one of the talent management tasks, and
the third part is to propose the potential HR system architecture for
talent forecasting.
Abstract: The IFRS for Small and Medium-sized Entities
(SMEs) was issued in July 2009 and currently regulators are
considering various implementation strategies of this standard.
Romania is a member of the European Union since 2007, thus
accounting regulations were issued in order to ensure compliance
with the European Accounting Directives. As the European
Commission rejected recently the mandatory use of IFRS for SMEs,
regulatory bodies from the Member States have to decide if the
standard will affect or not the accounting practices of SMEs from
their countries. Recently IASB invited stakeholders to discuss the
revision of IFRS for SMEs. Empirical studies on the differences and
similarities between national standards and IFRS for SMEs could
inform decision makers on the actual level of convergence in
different countries. The purpose of this paper is to provide empirical
evidences on the convergence of the Romanian regulations with IFRS
for SMEs analyzing the results in the context of the last revisions
proposed to the EU Accounting Directives.
Abstract: The paper shows some ability to manage two-phase
flows arising from the use of unsteady effects. In one case, we
consider the condition of fragmentation of the interface between the
two components leads to the intensification of mixing. The problem
is solved when the temporal and linear scale are small for the
appearance of the developed mixing layer. Showing that exist such
conditions for unsteady flow velocity at the surface of the channel,
which will lead to the creation and fragmentation of vortices at Re
numbers of order unity. Also showing that the Re is not a criterion of
similarity for this type of flows, but we can introduce a criterion that
depends on both the Re, and the frequency splitting of the vortices. It
turned out that feature of this situation is that streamlines behave
stable, and if we analyze the behavior of the interface between the
components it satisfies all the properties of unstable flows. The other
problem we consider the behavior of solid impurities in the extensive
system of channels. Simulated unsteady periodic flow modeled
breaths. Consider the behavior of the particles along the trajectories.
It is shown that, depending on the mass and diameter of the particles,
they can be collected in a caustic on the channel walls, stop in a
certain place or fly back. Of interest is the distribution of particle
velocity in frequency. It turned out that by choosing a behavior of the
velocity field of the carrier gas can affect the trajectory of individual
particles including force them to fly back.
Abstract: This study examines age and sex patterns of
children-s disability in the Parila union of Rajshahi, Bangladesh. For
this we assumed that (1) prevalence of disability patterns and its
severity in the middle childhood are higher than in the infancy or
latter childhood in the Parila union of Rajshahi, (2) prevalence of
disability patterns and its severity among the boys compared to girls
are higher in the study area of Bangladesh. In order to examine the
assumptions 102 samples, including their mothers were selected
based on snowball process and the respondents were individually
interviewed with semi-structured questionnaire method. The results
of the study suggest that disability patterns and its severity among the
male children were two-fold higher than the female children. In
addition, these patterns of children-s disability and its severity in the
middle childhood were also higher than in the infancy or latter
childhood. Further study should conduct how socio-structural factors
influence age and sex patterns of children-s disability patterns and its
severity in Bangladesh.
Abstract: Modern retailers such as hypermarket/supermarket
need to be more customer-oriented in order to survive in today-s
competitive business world. As a result, the investigation of
determinant factors of store loyalty becomes important issue for
modern retailing players. This study suggests that consumers- store
loyalty in the modern retailing market (hypermarkets and
supermarkets) is influenced by environmental factors (such as store
image, store personnel). Using a model of stimulus-organismresponse
(S-O-R), this research examines S-R relationship of store
loyalty. S-O-R framework is derived from the existence literature and
tested empirically based on Indonesian consumers- experience. The
stimuli for this study are store image, store personnel, satisfaction
and culture factors. Affect, or the consumers- liking to modern
retailing stores, mediates the chosen environmental factors on
consumer-s store loyalty. The findings showed that store image, store
satisfaction and culture have significant positive relationship to store
loyalty via affect.
Abstract: Recently, the RFID (Radio Frequency
Identification) technology attracts the world market attention as
essential technology for ubiquitous environment. The RFID
market has focused on transponders and reader development.
But that concern has shifted to RFID software like as
high-valued e-business applications, RFID middleware and
related development tools. However, due to the high sensitivity
of data and service transaction within the RFID network,
security consideration must be addressed. In order to guarantee
trusted e-business based on RFID technology, we propose a
security enhanced RFID middleware system. Our proposal is
compliant with EPCglobal ALE (Application Level Events),
which is standard interface for middleware and its clients. We
show how to provide strengthened security and trust by
protecting transported data between middleware and its client,
and stored data in middleware. Moreover, we achieve the
identification and service access control against illegal service
abuse. Our system enables secure RFID middleware service
and trusted e-business service.
Abstract: To comply with the international human right
legislation concerning the freedom of movement, transport systems
are required to be made accessible in order that all citizens, regardless
of their physical condition, have equal possibilities to use them. In
Hungary, apparently there is a considerable default in the
improvement of accessible public transport. This study is aiming to
overview the current Hungarian situation and to reveal the reasons of
the deficiency. The result shows that in spite of the relatively
favourable juridical background linked to the accessibility needs and
to the rights of persons with disabilities there is a strong delay in
putting all in practice in the field of public transport. Its main reason
is the lack of financial resource and referring to this the lack of
creating mandatory regulations. In addition to this the proprietary
rights related to public transport are also variable, which also limits
the improvement possibilities. Consequently, first of all an accurate
and detailed regulatory procedure is expected to change the present
unfavourable situation and to create the conditions of the fast
realization, which is already behind time.
Abstract: The tracing methods determine the contribution the
power system sources have in their supplying. The methods can be used
to assess the transmission prices, but also to recover the transmission
fixed cost. In this paper is presented the influence of the modification of
commons structure has on the specific price of transfer. The operator
must make use of a few basic principles about allocation. Most
tracing methods are based on the proportional sharing principle. In this
paper Kirschen method is used. In order to illustrate this method, the 25-
bus test system is used, elaborated within the Electrical Power
Engineering Department, from Timisoara, Romania.
