"End-of-life Vehicle
(ELV) recovery is a promising strategy to minimize the environmental impact of
automotives on environmental sustainability. This study aims to assess the
community?s knowledge from a socio-technical perspective on ELV. A survey was
conducted in Japan and Malaysia to assess public perception on ELV recovery.
The results showed that the communities in both countries have basic knowledge
and a reasonably good level of awareness on environmental issues and recovery
strategies such as recycling. However, there is a high level of uncertainty on
the concept of ELV reuse and remanufacturing, as more than 50% of respondents
were unsure of their willingness to participate in ELV initiatives. The
respondents agreed that the industry and government should take the necessary
steps to support the reuse strategy. The paper concludes with suggestions from
a socio-technical perspective, which aim to ensure an effective implementation
of ELV recovery through reuse and remanufacturing."

"This paper describes the
case study of Semanggi intersection in Jakarta, a dynamic model of emission
reduction in the land transportation sector. The urban transportation system is
a complex system with multiple variables, feedback loops, and is influenced by
social, economic and environmental factors. The proposed model consists of two
submodels: Vehicle Fleet and Emission Calculation. The model runs in
Powersim Studio software using data from the Indonesia Japan Economic
Partnership Agreement, and the Traffic
Management Centre of the Indonesian National Police. The test was conducted by developing two scenarios:
Business As Usual and Intention. The estimated results to be
obtained using the first scenario in 2021 should be 1,113,398 units, while the
second scenario is estimated to produce 850,733 units. We hypothesize that the
Intentional Approach will have a more significant impact than the Technical
Approach, which requires more investment. The Intentional Approach is designed to improve the intention of
private car users to switch to public transportation. The Technical Approach to the emission measurement of every
vehicle in a certain area is the data of vehicle emission which are usually
taken to determine the current condition. This research will no doubt
have a positive impact on emission reduction in Jakarta."

"seiring dengan kebutuhan TNI AU akan alutsista yang semakin maju, perkembangan dunia UAV juga mengalami perkembangan yang cukup signifikan, kenutuhan yang terus meningkat tersebut akan membuat ketergantungan terhadap pihak asing jika tidak berusaha untuk mengembangkan teknologi bidang kedirgantaraan tersebut. sebenarnya dalam negeri kini sudah banyak pihak-pihak penghobi aeromodelling yang bisa mendesain struktur rangka sendiri. pada makalah ini desimpurnakan vortex blade element theory, sehingga dihasilkan propeller yang sesuai dengan kebutuhan."

"The temperature and humidity inside poultry houses are highly coupled through nonlinear psychrometric processes, and the limitation of actuators makes this type of system difficult to control. To understand the dynamics of such systems and further to design a suitable controller, in this study, the mathematical model for a closed poultry house was derived from the governing equations of the various components related to the poultry house, including the energy and mass balance and the psychrometric correlations of the moist air. The model was simulated and the simulation result was compared to the data collected experimentally for model verification and control gains estimation. Under the assumptions of 70 percent Active Mixing Volume (AMV) with the constant maximum ventilation rate in the case study, the temperature and the relative humidity simulated results were in the good agreement with the real physical plant data. At the front, the middle and the rear part of
the poultry house, the root-mean-square error (RMSE) obtained for internal temperatures are 1.17oC, 0.68oC, and 0.46oC, respectively. And
those data for relative humidity are 4.31%, 8.07%, and 53.54%, respectively."

"The cloud is an outstanding
platform to deal with functionally equivalent services which are exponentially
increasing day-by-day. The selection of services
to meet the client requirements is a subtle task. The services can be selected by
ranking all the candidate services using their network and non-network Quality-of-Service (QoS) parameters, which is formulated as a NP hard optimization problem. In this paper, we
proposed a linear discriminant analysis (LDA) based a four level matching model for service selection based on QoS parameters,
which includes description matching of a service, matchmaking phase, LDA-based QoS matching and ranking. The LDA-service
selection agent is deployed on each cloud to classify services into classes and
rank the services based on the aggregate QoS value of each service. Finally,
the test results show the efficiency in service selection with minimal
discovery overhead, significant reduction in the computation time and the
number of candidate services to be considered."

"An effective and real-time traffic information network is highly important and could contribute to decreasing traffic volume and costs by reducing fuel consumption and saving time for drivers in reaching their destinations. This study provides an extensive analysis regarding the drivers? acceptance levels of the current implementation of the Intelligent Transport System (ITS) in Kuala Lumpur. A proposed model from the literature review based on the known Technology Acceptance Model (TAM) is introduced. The ITS system characteristics, information quality, system quality, and service quality were investigated as external variables. The resulting analysis showed that information quality is the highest influential factor followed by system quality. The results also revealed that service quality had no effect on acceptance levels."

"Nanostructured zincoxide (ZnO) was synthesized via a sonochemical method. The effect of the duration of ultrasonic irradiation in a continuous mode on the generated particles was investigated. Additionally, the effect of flowing either air or nitrogen during the sonication process was investigated. Zinc nitrate and
ammonia water-based solutions were selected as chemicals without the addition
of other surfactants. The generated particles indicated that a wurtzite
structure of ZnO in a hexagonal phase was formed with a crystalline size that increased
as the ultrasound irradiation time increased. The morphology of the generated
ZnO particles could be changed from flowerlike to needlelike structures via
continuous ultrasound irradiation over one to two hours, resulting in increases
in the particle lengths and decreases in the particle diameters from 200 to 80
nm. Photoluminescence intensity was also increased with increases in the ultrasonic
irradiation times. Photoluminescence spectra were also influenced by the
atmospheric environment. Two bands centered at 390 and 500 nm were generated
under a nitrogen environment. On the other hand, a single wide band with a peak
at around 430 nm was found for particles generated under an air environment. It
can be applied for light emitting diodes (LED) or laser fabrication with a
controlled emitting band."

"This book provides a thorough overview of cutting-edge research on electronics applications relevant to industry, the environment, and society at large. It covers a broad spectrum of application domains, from automotive to space and from health to security, while devoting special attention to the use of embedded devices and sensors for imaging, communication and control. The book is based on the 2017 ApplePies Conference, held in Rome, Italy in September 2017, which brought together researchers and stakeholders to consider the most significant current trends in the field of applied electronics and to debate visions for the future. Areas addressed by the conference included information communication technology; biotechnology and biomedical imaging; space; secure, clean and efficient energy; the environment; and smart, green and integrated transport. As electronics technology continues to develop apace, constantly meeting previously unthinkable targets, further attention needs to be directed toward the electronics applications and the development of systems that facilitate human activities. This book, written by industrial and academic professionals, represents a valuable contribution in this endeavor."
