  • Genetic Algorithm Amplifier Biasing System (GAABS): Genetic Algorithm for Biasing on Differential Analog Amplifiers
    DigitalCommons@CalPoly, 2018
    Co-Authors: Whalen Sean
    Abstract:

    Genetic Algorithm Amplifier Biasing System (GAABS) - Senior Project Analysis Summary of Functional Requirements This project integrates LTSpice with a python script that runs a genetic algorithm to bias a differential amplifier. The system biases the amplifier with 2 different voltages, the base voltage for the PNP BJTs of the active loads and a voltage controlling the current of the current sink. The project runs via a python script, gets data from LTSpice’s command line call, and iteratively runs until the system is biased to achieve the greatest gain on an arbitrary input voltage. Primary Constraints Some of the main challenges associated with this project are going to be the getting the genetic algorithm to work consistently and getting LTSpice to integrate well with command line. The genetic algorithm, though controlled, will have a good deal of randomness involved with converging to a certain gain value. A strong genetic algorithm should be able to converge to the same value every time and should be designed accordingly. Having never experienced using LTSpice via command line, but it shouldn’t be too difficult to call. Collecting data from the simulation will be challenging, but ideally there would be resources for help on that portion. Economic The original estimated cost for components is $0, as all the software should be open source and free to download and access to a computer should be considered free. There is no hardware, as it’s all simulation, so there is nothing there to be purchased. Bill of Materials Item Cost Bootcamp Application $0 Python 2.7 $0 LTSpice $0 Total $0 The total did end up being $0 as anticipated. Everything that could be downloaded was free to download. The original time for development at the start of the project was anticipated being 100+ hours. Given the need to integrate everything and work to get the genetic algorithm working well, 100 hours seemed reasonable. In the end, it did end up taking roughly 80 hours. Having to try different approaches to the problem took up a lot of time and tweaking the genetic algorithm (and running the tests) took a long time, but the integration was easy to set up. The integration being easy shaved a large chunk of time off the projected time to complete the project. Manufacturing Information This code is open source on GitHub, and won’t be manufactured on a commercial basis. Environmental There are no environmental impacts associated with manufacturing. The only potential impact on the environment of this project would be the heat generated by a computer running the script. The script takes up to 30+ minutes to run, and it is somewhat intensive in terms of computing power; this would generate heat from the computer running it, and heat from computers cannot be neglected in terms of their effect on global warming. However, the heat that would be generated by 1 computer should be considered negligible, as there are much greater contributors. Manufacturability As stated before, there are no issue with manufacturing this project because it’s open source. Everything needed to run the code can be found online for free download, and the script can be taken from online. Sustainability The code runs on Python 2.7 and the current version of LTSpice. It should have no issue running on later versions of Python and LTSpice, so long as there are no drastic changes. The project is on the internet, and so it will be sustainably existing as long as it’s not taken down by GitHub. Upgrades that would improve the design of the project include running more children per generation in simulation at once to speed up runtime and taking more generations to come to the best bias voltages to make it more accurate. Ethical There is no Ethical Implication to the use or design of this project. Health and Safety Other than long term computer use’s impact on a user, there are no health and safety concerns with this project whatsoever. Social and Political There are no social and political Implications to the use or design of this project. Development During the development of this project, I had to learn how to use Python on a much deeper level. My CPE 101 class was in Python, but that was winter quarter of 2015, and this project took place in the winter and spring of 2018. I remembered very little, but I got to see a lot of the functionality of python in terms of it being a great language for running scripts to work on a variety of applications across platforms. I had to research a lot on genetic algorithms and how to implement them, as that was a huge portion of this project

  • War as a Workplace: Ethical Implications of the Occupational Shift
    'Informa UK Limited', 2019
    Co-Authors: Dobos N
    Abstract:

    Soldiering has traditionally been thought of as something radically different from a job or career, but things are changing. Sociologists have observed an “occupational shift” in military service. A corollary is that soldiers are part of the workforce, and an Ethical Implication is that soldiers are presumptively entitled to the protection of workplace rights. In recent years, the push to have this acknowledged has gained momentum. The present article begins to explore what it would mean in practice if standard workplace rights were extended to armed forces personnel. The question, more specifically, is how this would constrain the war-making privileges of the state

  • How trust can drive forward the user acceptance to the technology? In-vehicle technology for autonomous vehicle
    Transportation Research Part A: Policy and Practice, 2018
    Co-Authors: Nadia Adnan, Shahrina Md Nordin, Mohamad Ariff Bin Bahruddin, Murad Ali
    Abstract:

    The autonomous vehicle innovation has a potential effect on traffic and it's a widespread issue in the academic municipal. Based on its feature, autonomous vehicle is expected to improve traffic flow, reduce accidents, reduce social exclusion and improve the utility of time on travel. It is increasingly accepted that the next step to the evolution of human transportation is the replacement of human as the driver by the Artificial-intelligence-capable machine. Regardless, the challenges remain especially in convincing the consumers to switch to autonomous cars despite the apparent benefits. In the past, papers highlighted individual trust toward machine as the key point to encourage acceptance of autonomous cars. This paper seeks to highlight the Ethical Implications of the autonomous technology and how it is related to the user acceptance of the technology. This paper reviewed recent studies on the Ethical Implications of the autonomous vehicle and the user acceptance of the technology. A systematic review of papers from the literature was done using Scopus, ISI and Web of Science. The results of the review have shown that the level of trust, which may vary on the sociodemographic profile of the users, has been studied as one of the factors for user acceptance. Many researchers also highlight Ethical Implication as an important aspect of autonomous technology that needs to be tended to. The researcher proposes that Ethical Implication can be an important element of user trust toward autonomous technology. Hence, there is a need to embed Ethical Implication as a construct for user trust leading to user acceptance model in future studies. In the line of this research review researcher was addressed the following comprehensive groups: examination of autonomous vehicle topographies and flexibility prototypes, consequences for street traffic and connectivity to substructure (specifically in the urban areas with the medium and low density), communal attitudes and apprehensions, transportable behaviour and plea, possible business models, and strategy Implications. Lastly, the main objective of this research article is to recognise critical problems for the growth of an effort cluster investigation to comprehend attitudes of possible manipulators of AVs and to highpoint autonomous vehicle growth issues for Malaysian lawful agencies.

  • Ethical Implication of Environmental Crises on African Societies: A Challenge to Future Humanity.
    2019
    Co-Authors: Ogar, Joseph Nkang
    Abstract:

    African societies are becoming aware of the shortcomings of Western capitalist value system, because of its aftermath on individual, society, and environment. Many of African conservationist values, moral attitudes and ways of life have been destroyed by the exploitative capitalist ethos of European colonialism and modernity. Three decades of African countries trying to build their economies like the Western models have left her people wallowing in poverty, and her environment exposed to hazards. With this new imbibed Western values, African population will continue to rise, as well as innovation in science and technology, thus, there is a growing need to put adequate measures in place against further environmental degradation. This paper tends to show the Ethical Implication of environmental crises on African societies. It concludes with the need for Africans to jettison western anthropocentric, capitalist and individualist values for her communal values. This paper further acknowledges that due to modernity, African value systems such as taboo and totems are being outdated. This paper proposes that scientific methods of environmental conservation and Christian ethics in the spirit of African communitarianism can go a long way in curbing ecological problems within the continent. This work is carried out with the philosophical method of analysis and exposition
