Abstract: Many people regard food events as part of gastronomic tourism and important in enhancing visitors’ experiences. Realizing the importance and contribution of food events to a country’s economy, the Malaysia government is undertaking greater efforts to promote such tourism activities to international tourists. Among other food events, the Ramadan bazaar is a unique food culture event, which receives significant attention from the Malaysia Ministry of Tourism. This study reports the empirical investigation into the international tourists’ perceptions, attraction towards the Ramadan bazaar and willingness in disseminating the information. Using the Ramadan bazaar at Kampung Baru, Kuala Lumpur as the data collection setting, results revealed that the Ramadan bazaar attributes (food and beverages, events and culture) significantly influenced the international tourist attraction to such a bazaar. Their high level of experience and satisfaction positively influenced their willingness to disseminate information. The positive response among the international tourists indicates that the Ramadan bazaar as gastronomic tourism can be used in addition to other tourism products as a catalyst to generate and boost the local economy. The related authorities that are closely associated with the tourism industry therefore should not ignore this indicator but continue to take proactive action in promoting the gastronomic event as one of the major tourist attractions.
Abstract: In the supply chain management customer is the most
significant component and mass customization is mostly related to
customers because it is the capability of any industry or organization
to deliver highly customized products and its services to the
respective customers with flexibility and integration, providing such
a variety of products that nearly everyone can find what they want.
Today all over the world many companies and markets are facing
varied situations that at one side customers are demanding that their
orders should be completed as quickly as possible while on other
hand it requires highly customized products and services. By
applying mass customization some companies face unwanted cost
and complexity. Now they are realizing that they should completely
examine what kind of customization would be best suited for their
companies. In this paper authors review some approaches and
principles which show effect in supply chain management that can be
adopted and used by companies for quickly meeting the customer
orders at reduced cost, with minimum amount of inventory and
maximum efficiency.
Abstract: Energy Efficiency Management is the heart of a
worldwide problem. The capability of a multi-agent system as a
technology to manage the micro-grid operation has already been
proved. This paper deals with the implementation of a decisional
pattern applied to a multi-agent system which provides intelligence to
a distributed local energy network considered at local consumer level.
Development of multi-agent application involves agent
specifications, analysis, design, and realization. Furthermore, it can
be implemented by following several decisional patterns. The
purpose of present article is to suggest a new approach for a
decisional pattern involving a multi-agent system to control a
distributed local energy network in a decentralized competitive
system. The proposed solution is the result of a dichotomous
approach based on environment observation. It uses an iterative
process to solve automatic learning problems and converges
monotonically very fast to system attracting operation point.
Abstract: This study investigated the relationships between the
active learning strategies (discussion, video clips, game show, role–
play, five minute paper, clarification pauses, and small group) and
academic achievement among a sample of 158 undergraduate
psychology students in The University of the West Indies (UWI),
Barbados. Results revealed statistically significant positive
correlations between active learning strategies and students’
academic achievement; so also the active learning strategies
contributed 22% (Rsq=0.222) to the variance being accounted for in
academic achievement and this was found to be statistically
significant (F(7,150) = 6.12, p < .05). Additionally, group work
emerged as the best active learning strategy and had the highest
correlation with the students’ academic achievement. These results
were discussed in the light of the importance of the active learning
strategies promoting academic achievement among the university
students.
Abstract: In large Internet backbones, Service Providers
typically have to explicitly manage the traffic flows in order to
optimize the use of network resources. This process is often referred
to as Traffic Engineering (TE). Common objectives of traffic
engineering include balance traffic distribution across the network
and avoiding congestion hot spots. Raj P H and SVK Raja designed
the Bayesian network approach to identify congestion hors pots in
MPLS. In this approach for every node in the network the
Conditional Probability Distribution (CPD) is specified. Based on
the CPD the congestion hot spots are identified. Then the traffic can
be distributed so that no link in the network is either over utilized or
under utilized. Although the Bayesian network approach has been
implemented in operational networks, it has a number of well known
scaling issues.
This paper proposes a new approach, which we call the Pragati
(means Progress) Node Popularity (PNP) approach to identify the
congestion hot spots with the network topology alone. In the new
Pragati Node Popularity approach, IP routing runs natively over the
physical topology rather than depending on the CPD of each node as
in Bayesian network. We first illustrate our approach with a simple
network, then present a formal analysis of the Pragati Node
Popularity approach. Our PNP approach shows that for any given
network of Bayesian approach, it exactly identifies the same result
with minimum efforts. We further extend the result to a more
generic one: for any network topology and even though the network
is loopy. A theoretical insight of our result is that the optimal routing
is always shortest path routing with respect to some considerations of
hot spots in the networks.
Abstract: The effect of thermally induced stress on the modal
properties of highly elliptical core optical fibers is studied in this
work using a finite element method. The stress analysis is carried out
and anisotropic refractive index change is calculated using both the
conventional plane strain approximation and the generalized plane
strain approach. After considering the stress optical effect, the modal
analysis of the fiber is performed to obtain the solutions of
fundamental and higher order modes. The modal effective index,
modal birefringence, group effective index, group birefringence, and
dispersion of different modes of the fiber are presented. For
propagation properties, it can be seen that the results depend much on
the approach of stress analysis.
Abstract: For the communication between human and computer
in an interactive computing environment, the gesture recognition is
studied vigorously. Therefore, a lot of studies have proposed efficient
methods about the recognition algorithm using 2D camera captured
images. However, there is a limitation to these methods, such as the
extracted features cannot fully represent the object in real world.
Although many studies used 3D features instead of 2D features for
more accurate gesture recognition, the problem, such as the processing
time to generate 3D objects, is still unsolved in related researches.
Therefore we propose a method to extract the 3D features combined
with the 3D object reconstruction. This method uses the modified
GPU-based visual hull generation algorithm which disables unnecessary
processes, such as the texture calculation to generate three kinds
of 3D projection maps as the 3D feature: a nearest boundary, a farthest
boundary, and a thickness of the object projected on the base-plane. In
the section of experimental results, we present results of proposed
method on eight human postures: T shape, both hands up, right hand
up, left hand up, hands front, stand, sit and bend, and compare the
computational time of the proposed method with that of the previous
methods.

Abstract: Nowadays there are lots of applications of power and
free conveyors in logistics. They are the most frequently used
conveyor systems worldwide. Overhead conveyor technologies like
power and free systems are used in the most intra-logistics
applications in trade and industry. The automotive, food, beverage
and textile industry as well as aeronautic catering or engineering are
among the applications. Power and free systems employ different
manufacturing intervals in manufacturing as well as in production as
temporary store and buffer. Depending on the application area, power
and free conveyors are equipped with target controls enabling
complex distribution-and sorting tasks. This article introduces a new
power and free conveyor design in intra-logistics and explains its
components. According to the explanation of the components, a
model is created by means of their technical characteristics. Through
the CAD software, the model is visualized. After that, the static
analysis is evaluated. This analysis helps the calculation of the
mandatory state of structures under force action. This powerful model
helps companies achieve lower development costs as well as quicker
market maturity.
Abstract: This study examines appearances of brand placement
as an alternative communication strategy in television series by
focusing on Yalan Dünya which is one of the most popular television
series in Turkey. Consequently, this study has a descriptive research
design and quantitative content analysis method is used in order to
analyze frequency and time data of brand placement appearances in
first 3 seasons of Yalan Dünya with 16 episodes.
Analysis of brand placement practices in Yalan Dünya is dealt in
three categories: episode-based analysis, season-based analysis and
comparative analysis. At the end, brand placement practices in Yalan
Dünya are evaluated in terms of type, form, duration and legal
arrangements.
As a result of this study, it is seen that brand placement plays a
determinant role in Yalan Dünya content. Also, current legal
arrangements make brand placement closer to other traditional
communication strategies instead of differing brand placement from
them distinctly.
Abstract: Efficient handoff algorithms are a cost-effective way
of enhancing the capacity and QoS of cellular system. The higher
value of hysteresis effectively prevents unnecessary handoffs but
causes undesired cell dragging. This undesired cell dragging causes
interference or could lead to dropped calls in microcellular
environment. The problems are further exacerbated by the corner
effect phenomenon which causes the signal level to drop by 20-30 dB
in 10-20 meters. Thus, in order to maintain reliable communication
in a microcellular system new and better handoff algorithms must be
developed. A fuzzy based handoff algorithm is proposed in this paper
as a solution to this problem. Handoff on the basis of ratio of slopes
of normal signal loss to the actual signal loss is presented. The fuzzy
based solution is supported by comparing its results with the results
obtained in analytical solution.
Abstract: Atmospheric plasma is emerging as a promising
technology for many industrial sectors, because of its ecological and
economic advantages respect to the traditional production processes.
For textile industry, atmospheric plasma is becoming a valid
alternative to the conventional wet processes, but the plasma
machines realized so far do not allow the treatment of fibrous
mechanically weak material.
Novel atmospheric plasma machine for industrial applications,
developed by VenetoNanotech SCpA in collaboration with Italian
producer of corona equipment ME.RO SpA is presented. The main
feature of this pre-industrial scale machine is the possibility of the inline
plasma treatment of delicate fibrous substrates such as fibre
sleeves, for example wool tops, cotton fibres, polymeric tows,
mineral fibers and so on, avoiding burnings and disruption of the
faint materials.

recovery and optimal generation as well as load patterns. The results
have been obtained on modified IEEE 14-bus system.
Abstract: Wireless Mesh Networks (WMNs) are an emerging
technology for last-mile broadband access. In WMNs, similar to ad
hoc networks, each user node operates not only as a host but also as a
router. User packets are forwarded to and from an Internet-connected
gateway in multi-hop fashion. The WMNs can be integrated with
other networking technologies i.e. ad hoc networks, to implement a
smooth network extension. The meshed topology provides good
reliability and scalability, as well as low upfront investments. Despite
the recent start-up surge in WMNs, much research remains to be
done in standardizing the functional parameters of WMNs to fully
exploit their full potential. An edifice of the security concerns of
these networks is authentication of a new client joining an integrated
ad hoc network and such a scenario will require execution of a multihop
authentication technique. Our endeavor in this paper is to
introduce a secure authentication technique, with light over-heads
that can be conveniently implemented for the ad-hoc nodes forming
clients of an integrated WMN, thus facilitating their inter-operability.
Abstract: This paper presents the development of an MODAPTS based cost estimating system to help designers in estimating the manufacturing cost of a assembly products which is belonged from the workers in working fields. Competitiveness of manufacturing cost is getting harder because of the development of Information and telecommunication, but also globalization. Therefore, the accuracy of the assembly cost estimation is getting important. DFA and MODAPTS is useful method for measuring the working hour. But these two methods are used just as a timetable. Therefore, in this paper, we suggest the process of measuring the working hours by MODAPTS which includes the working field-s accurate information. In addition, we adduce the estimation method of accuracy assembly cost with the real information. This research could be useful for designers that can estimate the assembly cost more accurately, and also effective for the companies that which are concerned to reduce the product cost.
Abstract: The design of a steam turbine is a very complex
engineering operation that can be simplified and improved thanks to
computer-aided multi-objective optimization. This process makes use
of existing optimization algorithms and losses correlations to identify
those geometries that deliver the best balance of performance (i.e.
Pareto-optimal points).
This paper deals with a one-dimensional multi-objective and
multi-point optimization of a single-stage steam turbine. Using a
genetic optimization algorithm and an algebraic one-dimensional
ideal gas-path model based on loss and deviation correlations, a code
capable of performing the optimization of a predefined steam turbine
stage was developed. More specifically, during this study the
parameters modified (i.e. decision variables) to identify the best
performing geometries were solidity and angles both for stator and
rotor cascades, while the objective functions to maximize were totalto-
static efficiency and specific work done.
Finally, an accurate analysis of the obtained results was carried
out.
Abstract: This paper presents an application of the improved
QFD method for determining the specifications of kitchen utensils
rack. By using the improved method, the subjective nature in original
QFD was reduced; particularly in defining the relationship between
customer requirement and engineering characteristics. The regression
analysis that was used for obtaining the relationship functions
between customer requirement and engineering characteristics also
accommodated the inaccurateness of the competitive assessment
results. The improved method which is represented in the form of a
mathematical model had become a formal guidance to allocate the
resource for improving the specifications of kitchen utensils rack.
The specifications obtained had led to the achievement of the highest
feasible customer satisfaction.
