A system for automatic detection of road damages is essential for logistics management. At the core of the system lies an algorithm for classification of damages. This work intends to establish such an algorithm. In the current proposal, the algorithm receives data of the probe vehicle rate of rotations, extracts statistics descriptive from the data to produce a feature vector, and finally, feeds the vector to a simple-three-layer neural network to classify the damages. The types of damages are limited to four cases: normal, pothole, speed bump, and expansion joint. For the development, a probe vehicle is used to produce 400 empirical data involving those four damage cases. By using Monte Carlo approach, the established neural network model is evaluated. The results show that the approach is able to classify the cases with 85% accuracy. The study also finds that the rates of pitch and roll to be the determining factors. © 2018 Institute of Physics Publishing. All rights reserved.

Herein, we report on the synthesis and characterization of p-type semiconductor indium phosphide/zinc sulphide (InP/ZnS) core/shell quantum dots (QDs) prepared via a simple solvothermal method and their potential application in bulk heterojunction (BHJ) flexible solar cell (SC). The BHJ SC composed of donor–acceptor (D-A) configuration at nanoscale provides larger interfacial junction area throughout the bulk volume of the photo-absorber D-A blend that facilitates excitons to efficiently dissociate within the bulk layer at D-A interface. Hence, InP/ZnS core–shell QDs and a fullerene derivative – phenyl C61 butyric acid methyl ester (PCBM) – are used as hybrid inorganic–organic D-A materials, respectively, to fabricate Ag/LiF/InP/ZnS-PCBM/P3HT/ITO/PET BHJ flexible SC. Indium tin oxide (ITO) coated on polyethylene terephthalate (PET), poly(3-hexylthiophene) (P3HT), lithium fluoride (LiF) and silver (Ag) are employed as a flexible substrate, hole transport layer (HTL), electron transport layer (ETL) and counter electrode, respectively. Photovoltaic (PV) properties of the fabricated BHJ flexible SC are studied under standard testing conditions (STC) i.e., 25 ⁰C, 1.5 AM global and 100 mW/cm² irradiation, which exhibit fill factor (FF) of 59 ± 0.02 % and power conversion efficiency (PCE) of 4.22 ± 0.05 %. Also, the heterojunction characteristics are investigated in dark condition (0 lx) to find series resistance (R_s), ideality factor (n), and reverse saturation current (I₀). X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM) and ultraviolet–visible (UV–vis) spectroscopy are performed to further investigate the properties of InP/ZnS-PCBM thin films. Transmission electron microscopy (TEM) image of InP/ZnS core/shell QDs confirmed the successful synthesis of QDs having an average size of 5 ± 1 nm. The InP/ZnS-PCBM D-A photo-absorber layer reveals its potential as one of good candidates for hi

This paper documents the development of portable kit for testing and mapping water quality in the field, Previously, thorough testing and reporting on well water quality required multiple steps, including costly and time-consuming lab work that often made such testing impractical. To address this problem, a water sampling kit was created that consists of a pocket PC, a GPS receiver and probes to test for pollutants. The kit automatically records the geographical coordinates at the water sampling site, as well as the data collected by the probes into one spreadsheet. The data is then linked to a GIS for display in a simple and usable manner. The efficiency of the kit gives it the potential to create a new standard for sampling water, particularly in the case of private wells, which are currently inadequately monitored due to scarce state resources, This paper describes the process of researching, designing, and testing the water sampling system.

The evaluation of the performance of information technology and information systems has, over the past three decades, been the object of numerous studies using a wide range of models. Few of them have focused on the study of efficiency, and even fewer still on the development of a specific research model. This paper helps to fill this gap by making a contribution towards formalizing a specific, original theoretical framework and conceptual model, one based on user confidence in ad hoc EDI technology and the risks associated with its use. The model is tested using data obtained from users of a value added network in the car insurance sector. The results of the data analysis, obtained through a series of principal component analysis methods with a Promax rotation and an Amos structural equation analysis, confirm the existence, on the one hand, of an optimal structure of EDI efficiency evaluation factors, and on the other hand, of the relevance of a data model that establishes a hierarchy aimed at explaining risk.

114th Annual ASEE Conference and Exposition, 2007

In today's competitive environment, employers consistently place high value on graduates that have demonstrated, relevant skills and knowledge. Perhaps the most effective way for acquiring such relevant capabilities is through co-op assignments and internships, yet these generally occur outside of the basic curricula even though they may have some educational credits attached. When incorporating the relevance of engineering practice directly into curricula, the use of input from external advisory boards is valuable and somewhat common. Industry visits, industrial seminar series, and incorporating external lecturers can also be effective in adding relevance to classes. However, while all of these are valuable, the most recognizable measure of having acquired relevant capabilities is achieving industry-specified professional validations and certifications. This requires carefully pre-designed curricula that account for multiple aspects. Merely providing instruction for professional certification tests and exams can border on training rather than educating, and is therefore more appropriate at a trade or commercial school rather than at a traditional academic institution. Using the advice and direction of external advisory boards, pertinent professional certifications have been identified and the content covered therein evaluated relative to its fit with various engineering and engineering technology curricula. By aligning aspects of professional certifications with established curricula, it is possible to integrate and intersperse the fundamentals and scope of the certifications into the curricula. As students move through their engineering or engineering technology programs they acquire the understanding and capabilities required to obtain appropriate professional certifications if they desire. This has been demonstrated for a variety of programs, including: information technology;engineering management;computer science;environmental, health and safety engineering te

CSMA/CA has been widely accepted as a Media Access Control scheme for Inter-Vehicle Communication systems. In CSMA/CA, a mobile station waits a frame transmission during a backoff interval based on random value. Then, the mobile station transmits the frame if the others do not transmit any frames. In this paper, we evaluate system performances of CSMA/CA from the viewpoint of a time efficiency and average frame delay time varying the range of random value by network simulations. © 2019 IEEE.

Dynamism of day-to-day activities in organizations is inextricably linked and there is a variety of information, insight and reasoning being processed between people and systems, in carrying out a business process. We argue that flexibility in processes could be managed in real time, using context information collected in the work environment. This paper proposes a context management architecture approach that aims to improve and automate dynamic process adaptation. We explain how process adaptation may occur in real time and discuss a scenario for this proposal © 2011 IEEE.

As global road infrastructure expands rapidly, especially in developing countries, maintaining the quality and safety of these roads becomes critical. However, many routes lack detours, and the swift deterioration of these busy roads raises serious concerns. Therefore, there is an urgent need for a cost-effective, quick inspection method. This study proposes a solution through drive-by monitoring. We utilized commercial buses with vibration sensors and Global Positioning System (GPS) devices. The GPS receivers, acting as accurate clocks, could record the bus’s location while providing space- and time-synchronization for the simultaneously measured vibration data. For this study, we installed an acceleration sensor under each bus seat. We can convert the recorded vehicle vibration data into road unevenness information, assuming specific vehicle parameters. To minimize errors, we updated the assumed parameters to align more closely with the average road unevenness versus the estimated unevenness from each bus. We employed a Genetic Algorithm, a search heuristic that mimics the process of natural evolution, to update these parameters. Through this methodology, we could estimate vehicle parameters and road unevenness, paving the way for an efficient, low-cost road inspection method. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Complexity and dynamism of day-to-day activities in organizations are inextricably linked, one impacting the other, increasing the challenges for constant adaptation on the way to organize work to address emerging demands. Market is demanding systems that are aware of organizations processes and able to evolve and adapt to new situations in everyday working activities. We argue that flexibility in processes could be managed in real time, by PAIS (Process-aware information systems), using context information collected in the work environment. This paper proposes CGAdapt, a context management architecture approach that aims to improve and automate dynamic process adaptation. We explain how process adaptation may occur in real time through an existent scenario using this proposal and discuss the value of context-awareness to reason about process alternative adaptations in a goal oriented approach. © 2012 IEEE.

As it starts at the end of the year 2019, the Covid-19 pandemic has already disturbed the condition of human life, socio-culture, and economics globally. As the virus is spreading from human to human, the need for a respirator mask is critical. One very well-known respirator mask is N95. The huge demand and high price of the N95 respirator effect create a bogus mask. This study proposes using blockchain in a global implementation of supply chain management of N95 respirator supply chain activity. Blockchain systems may help to reduce people's worldwide anxiety about the spread of N95 respirator counterfeits. The method used in this research is a systematic literature review and proposing a blockchain framework base on blockchain components. The implementation can use RFID at the level of manufacturers, distributors, and sellers. Using QR code or RFID stickers are possible in the level of customers or buyers. The result of this research is a proposal of blockchain technology for N95 respirator supply chain management systems, N95 respirator supply chain activities workflow, and a use case diagram. © 2021 IEEE.
