The Philippines is a country prone to natural disasters, such as typhoons. The present study aimed to investigate the response efficacy of the Filipino population under Typhoon Conson 2021, also known as Typhoon Jolina. A stepwise multiple linear regression was utilized to assess a variety of latent variables in the Protection Motivation Theory, such as perceived severity, self-efficacy, response efficacy, and response cost, along with an additional latent variable, geographical perspective. A sum of 388 participants voluntarily participated in a self-administered survey that consisted of 50 questions. It was found that the independent variables, such as geographical perspective, perceived severity, and self-efficacy were proven to have predictive ability on the dependent variable, response efficacy. The findings of this study could serve as a valuable guideline for planners and future researchers seeking to improve preparedness and response efficacy for typhoons. Furthermore, this study can also be employed by local government authorities to establish policies and strategies aimed at natural disaster risk protection. © 2023 IEEE.

The cost of commercial vehicle operation includes fuel, vehicle purchase/replacement/maintenance, and driver/staff,...,etc. Among these costs, fuel is the one that is not only cost-concerned but also environment-concerned. The fuel consumption is highly correlated with the vehicle traveling distance and driving behavior patterns and the emission of carbon dioxide (CO2) from the vehicle operations is one major contributing factor to the greenhouse effect that all human beings are suffering. How to utilize vehicles more efficiently in terms of time and travelling distance and reduce the carbon dioxide emission has become an important issue. Not to mention that many countries/areas have taken acts such as new laws for emission limitations to protect the environment. Advanced technologies such as Global Positioning systems (GPS) can generate the real-time location information of commercial vehicles. These data, analyzed by appropriate data mining technologies, can be used for fleet management systems such as vehicle route planning and driving behavior analysis. In this study, research team cooperating with Taiwan's largest commercial vehicle fleet, Formosa Plastics Transport Corp. (FPTC), deploy GPS-based vehicle tracking and communication systems and apply data mining technologies to develop a new fleet management system that is not only cost-efficient but also environment-friendly. The results include reduced transportation costs, lowered emissions, improved driving behaviors, and a greener fleet.

Traffic incidents are non-recurring events that disrupt normal traffic flow and can have negative impacts on traffic operations, safety, and economy. As a result, there is a growing need for developing effective and reliable Automatic Incident Detection (AID) systems to detect incidents as early as possible to minimize their impacts. Machine Learning models, such as Neural Networks and Random Forests, have been utilized to develop AID models. However, the performance of machine learning models is significantly determined by its hyperparameters that need to be tuned to improve its performance in detecting incidents accurately and quickly. In this study, incident and normal traffic scenarios were generated using traffic simulator data, which is used to train and test a Random Forest incident detection model. The proposed methodology uses VISSIM microsimulation software to generate a diverse dataset of incident and normal conditions scenarios. Traffic parameters such as flow rate, speed, and occupancy at upstream and downstream stations were used as input variables for the model. The Random Forest model was trained and tested through RapidMiner software with 5-fold cross validation. Model performance was enhanced through the model hyperparameters tunning. An improvement of 0.35% in the F-score and 0.15% in the overall accuracy was achieved compared to the default model parameters. Findings of this study suggest that the tunning of hyperparameters of Random Forest models is crucial for developing accurate AID systems. The proposed methodology and optimized hyperparameter values provided by this study can be used as a guideline for developing Random Forest models for incident detection in transportation systems. Overall, this study contributes to the development of accurate and efficient traffic incident detection systems, which could help to mitigate the negative impacts of traffic incidents and improve transportation operations, safety, and economy. © 2023 Computers an

Teaching engineering and technology subjects involves conveying understanding of abstract information structures and processes such as complex telecommunications protocols, complex mathematical concepts, and data structures. These are multidimensional and can be difficult to grasp quickly. Supported by a Hewlett-Packard (HP) Technology for Teaching grant, the School of engineering and Technology at National University has embarked on a project to enable students to grasp these complex concepts more quickly and easily, using continuous dialog among students and instructors as the structures are first introduced and then examined from multiple perspectives through real-time interaction among students, small groups, and instructors. HP Wireless Tablet PCs are used to discuss and experiment with diagrams and processes in realtime. This allows combining lectures and problem-solving sessions into a single class session. Our hypothesis is that: 1) an in-depth learning of theory is accomplished, and 2) student engagement is enhanced. Presentation of theory by the instructor is integrated with application while the theory is still in the student's short-term memory. Students no longer have to wait for a separate session such as a recitation session to apply the concepts. This approach often takes less time. In addition to accelerating the learning process, expert instructors find this approach more rewarding as students grasp new concepts more quickly. Analysis of data captured from both students and instructors are presented to support our hypotheses, and our results are compared with similar research carried out by other universities. In addition, the level of interaction enabled by the use of HP Tablets in on-line classes is discussed. The best teaching tools available in existing on-line teaching platforms are compared with the additional tools available in on-site courses when every student has a wireless Tablet PC and specific recommendations are made to on-line teachi

This research examines the possibility of the US electric utilities' transition from closed to open systems, while taking steps towards new market orientation. By employing an inductive approach, it observes recent developments in two fronts: First, it observes that more renewable energy sources have been added to the power generation mix, and that utilities advertise their renewable energy related efforts through their websites. Second, it looks at the business environment from the perspective of market orientation. For this, the shifts in the business environment were put under the lens of four driving factors: customer support, regulation, competition, and technology.

SAE 2011 Commercial Vehicle engineering Congress, COMVEC 2011

作者： Eglseer, Andreas Winter, Martin Program Management - Hybrid Systems Magna Powertrain Engineering Center Steyr GmbH and Co KG Steyrer Str. 32 A-4300 St. Valentin Austria

Main topics are the development and the build-up of an 18ton hybrid truck with a parallel hybrid drivetrain. With this truck it is possible to drive up to 3 kilometers in the pure electric driving mode. In this R&D Project the engineering Center Steyr, a company of MAGNA Powertain has developed a hybrid truck with an integrated motor generator (IMG) including a clutch system for pure electric driving. Also a Li-Ion power battery, electrified traction voltage auxiliaries (steering pump, air compressor and climate compressor) and a cooling system for the new power electric components. The beginning of the paper shows a detailed layout of the developed hybrid truck. Chapter two shows the developed simulation model which is used for the dimensioning and for detailed simulations of hybrid drivetrains. To simulate thermal effects, a co-simulation environment between a longitudinal dynamics and thermal management software is applied. The longitudinal dynamics software calculates the propulsion power which determines the thermal load of the components. Particular attention was given to the electrical and thermal behavior of the traction battery. The coupling of longitudinal and thermal simulation enables a realistic computation of the energy use, since the effects such as the change of efficiency by temperature and load can be taken into account. This behavior has a high influence in the development and tuning of the vehicle's components and operating strategy. Therefore a special focus is given to the operation strategy of hybrid commercial vehicles. Finally an application shows simulated data of the hybrid commercial vehicle on standardized driving cycles and also cycles with a high proportion of urban driving. These simulations show a meaningful influence on the temperature of the components, especially the battery. To gain high market shares for hybrid trucks the total cost of ownership will be the main driver, so the development of affordable hybrid components (battery

Proton exchange membrane (PEM) fuel cells have attracted significant attention due to their low operating temperature, high efficiency, and minimal emissions. Especially when hydrogen is used as fuel, water is the only product. Among the various components of PEM fuel cells, the membrane is crucial one because it enables the transfer of protons from the anode to the cathode, while ensuring that the fuel and oxidant remain separate and do not mix. Hightemperature operation (above the boiling point of water) is desired in PEM fuel cells as it enhances the kinetics and improves water management. However, the current most widely used membrane, Nafion, cannot operate at high temperatures above 90°C due to the membrane's dehydration, resulting in decreased proton conductivity and eventually, fuel cell efficiency. To overcome this issue, this study focuses on the development of new and potentially high-temperature composite membranes. Zirconium silicate, (ZrSiO4)/Polyvinylidene fluoride (PVDF) composite membranes were synthesized in this work with the following ratios: 0 wt.%, 1.5 wt.%, 3 wt.%, and 8 wt.% per mass of membrane solution via a solution casting method. Their proton conductivity was evaluated. The results showed that the addition of ZrSiO4 nanoparticles to the PVDF matrix significantly enhances the proton conductivity of the composite membranes. The highest conductivity value obtained was 2.15 x10-3 Scm-1 with a concentration of 8 wt.% ZrSiO4. The promising proton conductivity reported in this work would be an indication of these membranes' potential in PEM fuel cell applications. © 2023 Computers and Industrial engineering.
