A Game-Theoretic Approach to Modeling Attacks and Defenses of Smart Grids
No full textAs optimization, user capabilities, and data-taking abilities are incorporated into next-generation power grids, or smart grids, they face cyber threats. The traditional electrical grid could only be damaged by physical attacks; however, the smart grid can suffer remote/cyber attacks, which have not been studied extensively in the literature. The electrical grid forms the backbone of the modern society and its security has significant implications in military settings. This paper applies game theory to model three-levels (power plants, transmission, and distribution networks) of defenses and attacks in smart grid network security. We characterize both the attacker and the defender (who interact at three network levels: distribution, transmission, and power plants) best responses and equilibrium strategies. We find that the defender’s best response is not only a function of direct attacks but also of the spread from connected networks. Sensitivity analyses of the equilibrium strategies show that when success probability of an attack against power plants reaches a threshold, the defender increases defending efforts for power plants. In contrast, the attack effort at all levels is not affected by this probability. This paper provides some novel insights to modeling and analyzing the emerging threats to the growing smart grid networks
Supporting the undocumented community in the era of Trump: a mixed-methods analysis of higher education
No full textIn this mixed-methods study, the issues affecting undocumented immigrants in the American higher education system are examined and discussed in relation to the current sociopolitical climate under the Trump administration. In the second chapter, quantitative data analyses of a survey given to students attending the University of Houston-Clear Lake are used to ascertain the level of prejudice among the sample student body; the results from the survey are further utilized to evaluate the correlations between stronger levels of prejudice and other defining characteristics of student identity, such as political affiliation, race, and major. Through discussing these results, significant connections between student identity, the Trump administration, and the undocumented community are established as a base to necessitate the need for more university intervention on behalf of undocumented students, which is discussed at length in the following chapter. In the third chapter, qualitative data analyses of interview and fieldwork data are used to orient the specific issues undocumented immigrants face while striving to achieve a higher education in the United States; these issues are outlined through six interconnected themes, including barriers to higher education, interorganizational cohesion, the formation of safe spaces, the sense of community between undocumented immigrants, and the concept of allyship toward the undocumented community. The study purposefully collected accounts from workers and volunteers, both documented and undocumented, of nonprofit organizations which actively engage in assisting undocumented immigrants for two key reasons: 1) to increase the generalizability of the findings to higher education institutions, and 2) to highlight the importance of undocumented voices and their allies in current academic literature. Through the analysis of these interviews, a dialogue is created that posits the importance of increasing existing university support for undocumented students, as well as proposing new methods universities could implement that are modeled after existing support tactics used by nonprofit organizations. The culmination of these two chapters provide a context for the importance of discussing undocumented rights in higher education, as well as offer multiple directions for future conversations and research to follow in advocating for the undocumented community
Data Visualization in Augmented Reality
Get PDFDuring critical procedures with limited resources, astronauts are expected to operate at a high level of efficiency and effectiveness. Recently, NASA has begun development of an advanced space suit design with many technological upgrades that will make astronauts more efficient and effective during extravehicular activities (EVAs). These upgrades include the introduction of an informatics subsystem projected on the inside of the helmet in an astronaut’s spacesuit. The current informatics system relies heavily on voice communication to a team member, “mission control,” and an EVA partner. During an EVA, the astronaut needs access to two streams of data: the instructions on how to complete the EVA task and sensor readings on the health of the suit. The task data stream is a spiral notebook attached to the forearm, the system health display, and controls are embedded in the spacesuit’s chest and must be monitored using a mirror on the forearm. The aim of this thesis is to reduce the workload of the astronaut user by leveraging an augmented reality display as part of the new informatics subsystem to increase efficiency and effectiveness. This includes two displays: the task display and the suit consumables display. Two types of consumable displays were tested. One resembles the current astronaut display on their arm and the other has a sprocket design. The subjects were asked to complete an activity using one of these two consumable displays. The subject’s performance was then compared between the two displays
