Written communication, unlike verbal communication, has one part of the communication loop missing; the receiver does not have the privilege of clarifying his doubts face to face with the sender. This may result in the sender and receiver taking out a different meaning from a common communication. Such a situation could emerge among a diversified workforce. The objectives of this paper are to highlight key constraints in written communication which can affect aviation safety, written communication processes employed in the aviation industry and simultaneously explore the training potential in order to standardize the written communication processes. The methods applied to this research were qualitative in nature. Results of this study reflect a preference towards reading a digital document rather than a hard copy of the same. Local/native languages have an effect on the English language. Owing to the differences in educational level, cultural background, the experience and exposure of the professionals, a document could be read and understood differently by different individuals. The style of the documents, such as clarity, simplicity, tone and brevity, can affect the reader’s ability to understand the information. Document layout, fonts, colour coding, are critical issues in timely and effective comprehension of information. Handwritten notes followed by schematic diagrams emerged as the most difficult documents to read and understand. The findings led to the following notable recommendations: frequent training of aviation staff under the guidance of some international body following a global and uniformed standard; development of standardized terminologies for recurring tasks and responsibilities; periodic assessment of written records carried out by different staff members.

This paper explores the logistical challenges of waste management and disposal within the Abu Dhabi Healthcare System, mainly referring to Abu Dhabi Health Services Company SEHA. It is recognized that healthcare systems in general, are often associated with the generation of various types of waste–medical, human, chemical, physical, etc. Thus, there is a real and urgent need for a robust, efficient and adequate waste management and disposal system–one which is logistically designed to dispose of such wastes in such fashion as to address and satisfy the health, welfare and environmental impacts of such hazardous wastes and material. This became even more critical with the Covid-19 pandemic. Hence, the necessity of the present study. Specifically, this study first identifies the logistical challenges associated with the collection and channeling of medical wastes. Thereafter, the study proposes improvements of the system for the efficient and environmentally sustainable management and disposal of such wastes, within the Abu Dhabi Healthcare System. The proposed smart system of waste management and disposal is recommended to overcome the prevailing deficiencies which are inherent in many healthcare systems - especially those that are focused merely on the process of only collection of medical wastes. Furthermore, the proposed smart system which adopts a novel and innovative logistical methodology, is designed to facilitate the proper management and disposal of healthcare wastes within the Abu Dhabi Healthcare System framework–in health, environmental and cost-effective terms.

Acute Kidney Injury (AKI) is a common medical condition with a high mortality rate. The incidence of AKI is exceptionally high in hospitalized patients, particularly those suffering from acute illness or postoperative patients. As AKI impacts both patient and financial outcomes, there has been a keen interest the disease. In recent years, AKI and big data synergies have been explored, particularly through electronic health records (EHR), ideal for AKI risk prediction. Due to the massive amount of data in EHR, machine learning (ML) models for data analytics are slowly rising. The application of ML is a promising approach due to its ability to collect EHR data and make predictions on AKI onset accordingly, instead of relying on independent health records. This systematic review aims to identify the opportunities and challenges that arise in integrating data analytics in AKI prediction.

The continuous utilization of fossil fuels has contributed to an increase in the greenhouse gases emissions and has boosted the demand for sources of renewable energy. Biomass has been identified as a viable feedstock for bioenergy production. The UAE has a relatively high coffee waste production, which makes it a potential feedstock for bioenergy production. Biomass can be converted into bioenergy or biofuel for example, by means of pyrolysis. This paper investigates the design and simulation bio-oil production from coffee waste in a fluidized bed reactor. The effect of the pyrolysis temperature on the biochar and bio-oil was also studied. The study showed that coffee waste is a suitable feedstock for bio-oil production in United Arab Emirates.

Jordan has limited energy resources combined with an increasing population over the past 20 years. There are limited resources such as fossil fuels and natural gas. Therefore, Jordan relies on imports of crude oil and natural gas. Jordan has several water reservoirs in the form of a dam that spread all over the country. No of these dams are utilized for hydropower production. In this work, we identified the dams that are potentially could be modified for energy production. We estimated the overall power production with recommendations and present and future challenges.

Due to the COVID-19 pandemic, various aspects of life, such as work, school and social gatherings, have shifted to online platforms. Pervasive technologies exist to cater to this shift, and in the case of online learning, they can not only sustain but help enhance the overall experience for both students and teachers. Ubiquitous or pervasive learning occurs at any time and place of the learner’s choice whenever the need arises, using tools from everyday life such as mobile devices. This style of learning allows students and teachers to engage in the learning process at their convenience. Teachers usually prefer conducting their lessons in a face-to-face environment, but the pandemic caused them to learn how to convey concepts online using pervasive technologies. In the span of a year, teachers’ initial apprehensions and resistance to online teaching are expected to have subsided, and in this paper, a group of teachers has been surveyed to assess the extent to which their attitudes towards online teaching and ubiquitous learning have changed. In the survey, the teachers were asked which of the stated benefits of online teaching they have experienced, what issues they have faced, their willingness to adopt increasingly advanced solutions to these issues and their inclination towards online teaching as compared to face-to-face in-classroom teaching. The findings from the survey indicate that although teachers’ attitudes towards pervasive learning have changed for the better, but due to the lack of physical contact, they would still prefer in-person classes, and the paper suggests future research directions to improve this aspect of the online teaching and learning process.

Successful product development (PD) requires using approaches capable of modelling and analyzing vague direct and indirect information flows among interrelated activities. This study proposes an approach integrating interpretive structural modelling (ISM) along with fuzzy Cross-Impact Matrix Multiplication Analysis (MICMAC) to achieve this end. While the ISM technique enables project managers visualizing information flows among the activities, fuzzy MICMAC analysis classifies activities with respect to their dependence and driving powers. This categorization provides PD project managers with a useful means to differentiate among PD activities and their mutual associations, permitting the identification of crucial activities. As a result, this leads to better supervision of the development process and thus reduces the risk of project overruns related to PD costs and lead-time. The approach is shown and validated using actual data obtained from a Taiwanese electronics company developing power line communication products.

One of the methods for handicapped people who can’t talk nor use their hands to communicate with the external world is using their eyes-gaze. Most of the commercial eye trackers used for typing are expensive and not user-friendly. The aim of this paper is to present a low-cost eye-tracking system that can be used easily by consumers. The basic idea of this project is as follows: An eye image is acquired from the web camera, and then the pupil will be detected using image processing techniques. Based on the estimated gaze direction, specific commands will be used to control the Graphical User Interface (GUI) which displays a screen that contains letters and special function buttons.

Punching shear capacity of fiber-reinforced polymer (FRP) reinforced slabs (RC)is usually predicted using theoretical models obtained from design codes and standards. In the load and resistance factored design (LRFD) approach, a reduction factor is applied to the member capacity as an implicit safety measure. The same reduction factors calibrated for conventional steel reinforced slabs are used for FRP reinforced slabs in design equations of existing codes. To accommodate for the specific properties and modes of failure of FRP slabs, a reliability analysis using Monte Carlo simulation (MCS) with a specific target reliability index (βT) was conducted to calibrate the LRFD design approach reduction factors for punching shear resistance formulas available in ACI 440.1R-15, JSCE.b-1997 and CAN-CSA-S806-12 codes.The conducted analysis has shown that ACI 440.1R-15 provided a conservative estimate for FRP slabs capacity in punching shear. It was concluded that using any reduction factor up to a 3.5 reliability index (5x10-6, probability of failure) is unnecessary. On the other hand, estimation using JSCE.b-1997 and CAN-CSA-S806-12 was more accurate. The calibrated reduction factors for these codes were close to the ones provided. For the CAN-CSA-S806-12 code, the calculated reduction factor was 0.75 with βT=3 and 0.6 for βT=3.5. These values are close to the estimated by CAN/CSA-12, which was 0.65 with βT=3.1. The calculated reduction factor for the JSCE code equation was 0.8 with βT=3 and 0.7 with βT=3.5. A unified reduction factor of 0.7 is proposed to be used for CAN/CSA-12 and JSCE codes equations that satisfy a reliability index of more than 3 for both codes within the practical range of the applied loads.

For the CAN-CSA-S806-12 code, the calculated reduction factor was 0.75 with βT=3 and 0.6 for βT=3.5. These values are close to the estimated by CAN/CSA-12, which was 0.65 with βT=3.1. The calculated reduction factor for the JSCE code equation was 0.8 with βT=3 and 0.7 with βT=3.5. A unified reduction factor of 0.7 is proposed to be used for CAN/CSA-12 and JSCE codes equations that satisfy a reliability index of more than 3 for both codes within the practical range of the applied loads.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"13 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89156630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
