Abstract: The purpose of this study is investigating the influences of logistics performance on organizational performance including both marketing & financial aspects, and showing the financial impacts of selecting the right marketing and logistics priorities in line with their supply chain type, and also giving the practitioners an advance identification of their priorities and participation types of supply chain, and the best combination of their strategies and resources in this regard. We made use of the original model’s questionnaire to gather all expert’s data and also SPSS and AMOS Ver.22 to analyze the gathered data. CFA method was also used to test whether a relationship between observed variables and their underlying latent constructs exists. Supply chain strategy implementation leads to logistics performance improvement, and marketing performance will be affected as well. Logistics service providers should focus on enhancement of supply chain performance, since logistics performance has been considered as a basis of evaluation of supply chain management strategy. Consequently, performance of the organization will be enhanced. This case is the first research made in Iran that analyzes the relationship between Logistics & Organizational performance in Home Appliances and Home Entertainment companies.
Abstract: In this paper, a brief review of the corrosion mechanism in buried pipe and modes of failure is provided together with the available corrosion models. Moreover, the sensitivity analysis is performed to understand the influence of corrosion model parameters on the remaining life estimation. Further, the probabilistic analysis is performed to propagate the uncertainty in the corrosion model on the estimation of the renaming life of the pipe. Finally, the comparison among the corrosion models on the basis of the remaining life estimation will be provided to improve the renewal plan.
Abstract: This research was aimed to investigate (1) the
relationship among local social movements, non-governmental
Organization activities and state measures deployment; and (2) the
effects of local social movements, non-governmental Organization
activities, and state measures deployment on conflict of local people
towards the Thai-Malaysian gas pipeline project. These people
included 1,000 residents of the four districts in Songkhla province.
The methods of data analysis consist of multiple regression analysis.
The results of the analysis showed that: (1) local social movements
depended on information, and mass communication; deployment of
state measures depended on compromise, coordination, and mass
communication; and (2) the conflict of local people depended on
mobilization, negotiation, and campaigning for participation of
people in the project. Thus, it is recommended that to successfully
implement any government policy, consideration must be paid to the
conflict of local people, mobilization, negotiation, and campaigning
for people’s participation in the project.
Abstract: The objectives of this research were to study the level
of influencing factors, leadership, supply chain management,
innovation, competitive advantages, business success, and affecting
factors to the business success of the mobile phone system service
providers in Bangkok Metropolitan. This research was done by the
quantitative approach and the qualitative approach. The quantitative
approach was used for questionnaires to collect data from the 331
mobile service shop managers franchised by AIS, Dtac and
TrueMove. The mobile phone system service providers/shop
managers were randomly stratified and proportionally allocated into
subgroups exclusive to the number of the providers in each network.
In terms of qualitative method, there were in-depth interviews of 6
mobile service providers/managers of Telewiz and Dtac and
TrueMove shop to find the agreement or disagreement with the
content analysis method. Descriptive Statistics, including Frequency,
Percentage, Means and Standard Deviation were employed; also, the
Structural Equation Model (SEM) was used as a tool for data
analysis. The content analysis method was applied to identify key
patterns emerging from the interview responses. The two data sets
were brought together for comparing and contrasting to make the
findings, providing triangulation to enrich result interpretation. It
revealed that the level of the influencing factors – leadership,
innovation management, supply chain management, and business
competitiveness had an impact at a great level, but that the level of
factors, innovation and the business, financial success and nonbusiness
financial success of the mobile phone system service
providers in Bangkok Metropolitan, is at the highest level. Moreover,
the business influencing factors, competitive advantages in the
business of mobile system service providers which were leadership,
supply chain management, innovation management, business
advantages, and business success, had statistical significance at .01
which corresponded to the data from the interviews.
Abstract: This study aims to explore and compare the current
condition of community radio stations in Phutthamonthon district,
Nakhon Pathom province, Thailand, as well as the challenges they
are facing. Qualitative research tools including in-depth interviews;
documentary analysis; focus group interviews; and observation, are
used to examine the content, programming, and management
structure of three community radio stations currently in operation
within the district. Research findings indicate that the management
and operational approaches adopted by the two non-profit stations
included in the study, Salaya Pattana and Voice of Dhamma, are
more structured and effective than that of the for-profit Tune Radio.
Salaya Pattana – backed by the Faculty of Engineering, Mahidol
University, and the charity-funded Voice of Dhamma, are
comparatively free from political and commercial influence, and able
to provide more relevant and consistent community-oriented content
to meet the real demand of the audience. Tune Radio, on the other
hand, has to rely solely on financial support from political factions
and business groups, which heavily influence its content.
Abstract: In this current era of competitive machinery productions, the industries are designed to place more emphasis on the product quality and reduction of cost whilst abiding by the pollution-preventing policy. In attempting to delve into the concerns, the industries are aware that the effectiveness of existing lubrication systems must be improved to achieve power-efficient and pollution-preventing machining processes. As such, this research is targeted to study on a plausible solution to the issue in grinding titanium alloy (Ti-6Al-4V) by using nanolubrication, as an alternative to flood grinding. The aim of this research is to evaluate the optimum condition of grinding force and surface roughness using MQL lubricating system to deliver nano-oil at different level of weight concentration of Silicon Dioxide (SiO2) mixed normal mineral oil. Taguchi Design of Experiment (DoE) method is carried out using a standard Taguchi orthogonal array of L16(43) to find the optimized combination of weight concentration mixture of SiO2, nozzle orientation and pressure of MQL. Surface roughness and grinding force are also analyzed using signal-to-noise(S/N) ratio to determine the best level of each factor that are tested. Consequently, the best combination of parameters is tested for a period of time and the results are compared with conventional grinding method of dry and flood condition. The results show a positive performance of MQL nanolubrication.
Abstract: In the recent years, a considerable level of interest has been developed on the use of earth in construction, led by its rediscovery as an environmentally building material. The Stabilized Earth Concrete (SEC) is a good alternative to the cement concrete, thanks to its thermal and moisture regulating features. Many parameters affect the behavior of stabilized earth concrete. This article presents research results related to the influence of the compacting nature on some SEC properties namely: The mechanical behavior, capillary absorption, shrinkage and sustainability to water erosion, and this, basing on two types of compacting: Manual and semi-automatic.
Abstract: Due to the randomness and uncertainty of wind energy, modern power systems integrating large-scale wind generation will be significantly impacted in terms of system performance and technical challenges. System inertia with high wind penetration is decreasing when conventional thermal generators are gradually replaced by wind turbines, which do not naturally contribute to inertia response. The power imbalance caused by wind power or demand fluctuations leads to the instability of system frequency. Accordingly, the need to attach the supplementary virtual inertia control to wind farms (WFs) strongly arises. When multi-wind farms are connected to the grid simultaneously, the selection of which critical WFs to install the virtual inertia control is greatly important to enhance the stability of system frequency. By building the small signal model of wind power systems considering frequency regulation, the installation locations are identified by the geometric measures of the mode observability of WFs. In addition, this paper takes the impacts of grid topology and selection of feedback control signals into consideration. Finally, simulations are conducted on a multi-wind farms power system and the results demonstrate that the designed virtual inertia control method can effectively assist the frequency regulation.
Abstract: This paper is primarily addressed to teachers who stand on the threshold of bringing technology and new media into their classrooms. Technology and new media, such as smart phones and tablets have changed the face of communication in general and of language teaching more specifically. New media has widespread appeal among young people in particular, so it is in the teacher’s best interests to bring new media into their lessons. It is the author’s firm belief that technology will never replace the teacher, but it is without question that the twenty-first century teacher must employ technology and new media in some form, or run the risk of failure. The level that one chooses to incorporate new media within their class is entirely in their hands.
Abstract: Large scale computing infrastructures have been widely
developed with the core objective of providing a suitable platform
for high-performance and high-throughput computing. These systems
are designed to support resource-intensive and complex applications,
which can be found in many scientific and industrial areas. Currently,
large scale data-intensive applications are hindered by the high
latencies that result from the access to vastly distributed data.
Recent works have suggested that improving data locality is key to
move towards exascale infrastructures efficiently, as solutions to this
problem aim to reduce the bandwidth consumed in data transfers, and
the overheads that arise from them. There are several techniques that
attempt to move computations closer to the data. In this survey we
analyse the different mechanisms that have been proposed to provide
data locality for large scale high-performance and high-throughput
systems. This survey intends to assist scientific computing community
in understanding the various technical aspects and strategies that
have been reported in recent literature regarding data locality. As a
result, we present an overview of locality-oriented techniques, which
are grouped in four main categories: application development, task
scheduling, in-memory computing and storage platforms. Finally, the
authors include a discussion on future research lines and synergies
among the former techniques.
Abstract: Recently, Graphene Nanoribbon Field Effect Transistors (GNR FETs) attract a great deal of attention due to their better performance in comparison with conventional devices. In this paper, channel length Modulation (CLM) effect on the electrical characteristics of GNR FETs is analytically studied and modeled. To this end, the special distribution of the electric potential along the channel and current-voltage characteristic of the device is modeled. The obtained results of analytical model are compared to the experimental data of published works. As a result, it is observable that considering the effect of CLM, the current-voltage response of GNR FET is more realistic.
Abstract: In this paper, we present the results of a study of TiN thin films which are deposited by a Physical Vapour Deposition (PVD) and Ion Beam Assisted Deposition (IBAD). In the present investigation the subsequent ion implantation was provided with N5+ ions. The ion implantation was applied to enhance the mechanical properties of surface. The thin film deposition process exerts a number of effects such as crystallographic orientation, morphology, topography, densification of the films. A variety of analytic techniques were used for characterization, such as scratch test, calo test, Scanning electron microscopy (SEM), Atomic Force Microscope (AFM), X-ray diffraction (XRD) and Energy Dispersive X-ray analysis (EDAX).
Abstract: This paper reports an experimental work that aimed to investigate the effects of clay brick waste, as part of fine aggregate, on rendering mortar performance. The brick, in crushed form, was from a local brick manufacturer that was rejected due to being of-standard. It was used to replace 33.33 %, 50 %, 66.66 % and 100 % by weight of the quarry sand in mortar. Effects of the brick replacement on the mortar key properties intended for wall plastering were investigated; these are workability, compressive strength, flexural strength, linear shrinkage, water absorption by total immersion and by capillary suction. The results showed that as the brick replacement level increased, the mortar workability reduced. The linear shrinkage increases over time and decreases with the introduction of brick waste. The compressive and flexural strengths decrease with the increase of brick waste because of their great water absorption.
Abstract: In this study, the possibility of using unground oil palm ash (UOPA) for producing foamed concrete is investigated. The UOPA used in this study is produced by incinerating palm oil biomass at a temperature exceeding 1000ºC. A semi-structural density of 1300kg/m3 was used with filler to binder ratio of 1.5 and preliminary water to binder ratio of 0.45. Cement was replaced by UOPA at replacement levels of 0, 25, 35, 45, 55 and 65% by weight of binder. Properties such as density, compressive strength, drying shrinkage and water absorption were investigated to the age of 90 days. The mix with a 35% of UOPA content was chosen to be used as the base material of a newly designed interlocking, mortar-less block system.
Abstract: This study extends technology acceptance model (TAM) to investigate the antecedents and consequences of social media adoption by tourists and travel agents. It compares their perceptions on social media adoption and its consequences. Online survey was addressed to tourists and travel agents for data collection purposes. Structural equation modelling was employed for analysis purposes. The findings revealed that the majority of tourists and travel agents involved in the study believe in the usefulness of social media adoption for travel planning and marketing purposes. They agree that adopting social media could change the attitude of tourists towards specific destination or attraction and influence their purchasing decisions. This study contributes to knowledge by extending TAM and provides some managerial implication to marketers.
Abstract: This paper examines Japanese life expectancy, and the declining birth rate to investigate the Japanese people’s view of death, and their consciousness of death. To support their perspectives toward death, “Eitai Kuyobo,” and tombs with Japanese animation will be focused as Japanese citizens have created unique tombs designs of their own tombs. With the methodological aspects, Japan’s birth and mortality rates, Japan’s average life expectancy, history of tombs, creation of one’s own tombs and types of marriage will be significant. By examining the Japanese history of tombs, social change and unique tombs, and the increase of mortality rate in Japanese super-aging society, this study contributes the change of people’s view toward tombs, and a view toward life and death. Accordingly, focusing on the change of people’s view toward tombs it is concluded that the change is caused by the increase of mortality rate in Japanese super-aging society.
Abstract: Nanocomposites based on polypropylene/polyamide 66 (PP/PA66) nanoblends containing organophilic montmorillonite (OMMT) and maleic anhydride grafted polypropylene (PP-g-MAH) were prepared by melt compounding method followed by injection molding. Two different types of nanoclays were used in this work. DELLITE LVF is the untreated nanoclay and DELLITE 67G is the treated one. The morphology of the nanocomposites was studied using the XR diffraction (XRD). The results indicate that the incorporation of treated nanoclay has a significant effect on the impact strength of PP/PA66 nanocomposites. Furthermore, it was found that XRD results revealed the intercalation, exfoliation of nanaclays of nanocomposites.
Abstract: This paper discusses a corner detection algorithm
for camera calibration. Calibration is a necessary step in many
computer vision and image processing applications. Robust
corner detection for an image of a checkerboard is required
to determine intrinsic and extrinsic parameters. In this paper,
an algorithm for fully automatic and robust X-corner detection
is presented. Checkerboard corner points are automatically
found in each image without user interaction or any prior
information regarding the number of rows or columns. The
approach represents each X-corner with a quadratic fitting
function. Using the fact that the X-corners are saddle points,
the coefficients in the fitting function are used to identify each
corner location. The automation of this process greatly simplifies
calibration. Our method is robust against noise and different
camera orientations. Experimental analysis shows the accuracy
of our method using actual images acquired at different camera
locations and orientations.
Abstract: This paper discusses the importance of having a good initial characterization of soil samples when thermal desorption has to be applied to polluted soils for the removal of contaminants. Particular attention has to be devoted on the desorption kinetics of the samples to identify the gases evolved during the heating, and contaminant degradation pathways. In this study, two samples coming from different points of the same contaminated site were considered. The samples are much different from each other. Moreover, the presence of high initial quantity of heavy hydrocarbons strongly affected the performance of thermal desorption, resulting in formation of dangerous intermediates. Analytical techniques such TGA (Thermogravimetric Analysis), DSC (Differential Scanning Calorimetry) and GC-MS (Gas Chromatography-Mass) provided a good support to give correct indication for field application.
Abstract: In this paper, a design of H.263 based wireless video
transceiver is presented for wireless camera system. It uses standard
WIFI transceiver and the covering area is up to 100m. Furthermore the
standard H.263 video encoding technique is used for video
compression since wireless video transmitter is unable to transmit high
capacity raw data in real time and the implemented system is capable
of streaming at speed of less than 1Mbps using NTSC 720x480 video.
