{"title":"Bias in Cognitive Engineering for Human-Machine Teaming Literature","authors":"Chuck Easttom","doi":"10.15864/ajse.2301","DOIUrl":"https://doi.org/10.15864/ajse.2301","url":null,"abstract":"Machines have a plethora of applications in spaces dangerous, hostile, or high-risk to humans. Given such applications, the fields of human-machine teaming and cognitive engineering, while nascent, are developing at a staggering rate. At the heart of these disciplines is a doctrine espousing an agent-centric concept based on common properties shared between machines and human operators. Symbiotically, the goal is to ensure machine and human mutually benefit from the teaming. Yet, the literature has been fixated on system design and machine-agent optimization for performance. Thus, the literature appears to be biased as it does not consider the cognitive requirements of the human agent. The problem then, is that recommendations from the literature focus on changing the machine to instigate less demanding human participation rather than adapting the human to induce optimal machine participation. For this reason, this work examined what characteristics of human-machine teaming literature demonstrate a statistically significant relationship with the category of focus in the same research. The characteristics-as-variables included author discipline, count of publications in the field, author affiliation, gender, and country of origin. A multinomial regression revealed a significant relationship with focus on the machine element as opposed to the human element in human-machine pairing in the cognitive engineering literature. Furthermore, author discipline, affiliation, and country of origin, demonstrated a significant bias effect towards the machine element in human-machine pairing literature.","PeriodicalId":93409,"journal":{"name":"American journal of engineering, science and technology","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85314766","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}

{"title":"Investigation of Soil at Different Locations of the Kathmandu Valley of Nepal","authors":"Neeru K. C., Khet Raj Dahal","doi":"10.11648/J.AJSET.20200504.16","DOIUrl":"https://doi.org/10.11648/J.AJSET.20200504.16","url":null,"abstract":"Investigation of soil bearing capacity helps in determining the design of the foundation of any structure. The main parameters which are commonly associated with the determination of liquefaction potential are the saturated sand and silty soils. Therefore, the present study was focused on the investigation of soil bearing capacity at different locations of Kathmandu valley of Nepal. The study was conducted during the period of 2019. Laboratory tests of the soil is the major tool of the investigation. The findings were analyzed in five categories emphasizing on bearing capacity, bulk density, natural moisture content, specific gravity and grain sieve analysis. The study found that the soil bearing capacity of the Kathmandu valley is low. Most of the places consist of Silty Clay soil, the consistency of which is very low. The study found that the highest and lowest value of bearing capacity was to be 151.2Kn/m2 and 61.66Kn/m2 respectively in Lalitpur District. Similarly, the highest and lowest value of bearing capacity of Kathmandu was found to be 163 Kn/m2 and 58.6 Kn/m2, whereas the same parameter in Bhaktapur, was found to be 6 Kn/m2 and 56.4 Kn/m2. Furthermore, the highest and lowest value of bulk density of the Lalitpur district was found to be 1.72 gm/cm3 and 2.1 gm/cm3 respectively, and for Bhaktapur it was declared to be 1.69 gm/cm3 and 2.01 gm/cm3 consecutively. In addition, the highest and lowest value of bulk density was calculated to be 1.55 gm/cm3 and 2.09 gm/cm3 for Kathmandu. Whereas, based on natural moisture content, the findings which were observed are the highest and lowest value of 4.4% and 99.85% at Lalitpur; and at Bhaktapur 10.72%, 75.95% respectively. Similarly, the highest and lowest value of Kathmandu district was found to be 4.76% and 99.8%. Moreover, based on specific gravity the highest and lowest values of Lalitpur District are 2.71 and 2.55, and at Bhaktapur district are 2.72 and 2.55, and at Kathmandu district are 2.72 and 2.55 respectively. Thus, the consistency of the soil at most of the places of the Kathmandu Valley ranges from soft to medium soft depending upon the value of N (i.e. 4 to 8). The study would like to suggest that the geotechnical investigation is necessary before the construction of a building in Kathmandu valley. Furthermore, the depth of the foundation should be increased, raft foundation is recommended to a greater extent. And, pile foundation is recommended, where the soil has very low bearing capacity.","PeriodicalId":93409,"journal":{"name":"American journal of engineering, science and technology","volume":"20 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85751244","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}

Appropriate statistical methods were applied, and a model for specifying the direction of increasing or decreasing of the significant process parameters was identified. A statistical forecasting program was typically designed for optimizing fibers extrusion processes using Microsoft Visual Basic program, and then the predicted and calculated results were evaluated. The main goal of current research is to give basics for the novel optimization approach, and how these novel modeling methodologies will help polymer designers in making the best experimental decision, saving the power, the time and the cost. The statistical models and designed programs are important for controlling the production process to enhance fibre properties. The produced fibres could be used for different textile applications, as an alternative to commercial chemical fibres at reasonable cost.","PeriodicalId":93409,"journal":{"name":"American journal of engineering, science and technology","volume":"80 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82140231","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}

The specific problem was CVSS severity rankings were specific to individual vulnerabilities, which limited\u0000 organizations to remediate vulnerabilities based on the potential downstream impact to other systems (Franklin, Wergin, & Booth, 2014). The purpose of this quantitative study was to use a pre-test / pro-test experiment to compare how cybersecurity professionals in the USMC rate vulnerabilities\u0000 before and after seeing examples of vulnerability chaining using the CVSS calculator. The research question was, what score would cybersecurity professionals in the USMC give individual vulnerabilities before and after seeing vulnerabilities used in combination to create a more severe cyberattack?\u0000 The research method used a quasi-experimental method with a pre-test / post-test design to identify how vulnerabilities would be scored before and after seeing a chained vulnerability demonstration. The results of the vulnerability scores were compared between the control and treatment groups,\u0000 as well as the CVSS scores provided in versions 2.0 and 3.0 for each vulnerability. Participants from the control group changed two vulnerabilities from a Medium score to a High score; CSRF (from 7.5 to 9.0) and XSS (8.3 to 9.0). The treatment group did not change any vulnerability scores\u0000 in a statistically significant manner, but the researcher found this was due to the overall higher scores for each vulnerability.","PeriodicalId":93409,"journal":{"name":"American journal of engineering, science and technology","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78595538","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}
