Improvement Of A* Algorithm In Path Planning Of Mobile Robot, Dexin Yao, Hongjun San, Yaru Wang, Haijie Sun, Jiupeng Chen, Xiaoyuan Yang

Journal of System Simulation

Abstract: To solve the problems of excessively redundant nodes, low search efficiency, and excessive path turning angle in the path search of the traditional A* algorithm, an improved A* algorithm is proposed to plan the optimal path. First, the amount of search neighborhood of the A* algorithm is increased to 24 to obtain a more accurate and comprehensive search field. Second, the angle search algorithm is introduced, eliminating the unnecessary nodes in the path search and making the search more target-oriented. Third, the heuristic function is weighted by the exponential attenuation through the relative position of the current point and …

Fringe-Field Actuation Of Mems Cantilever Resonators: Capacitance Model For Frequency-Amplitude Response Of Parametric Resonance, Miguel A. Martinez, Dumitru I. Carantu

Mechanical Engineering Faculty Publications

The paper investigates the frequency-amplitude response of micro-electromechanical system (MEMS) cantilever beams, which are actuated by the fringe field at parametric resonance. In this design, a micro cantilever beam (flexible electrode) and a ground plate (fixed electrode) are placed in parallel and connected through an AC voltage. The electrostatic force is due to electric field lines within the volume directly between the cantilever and the ground plate. The parallel-plate capacitance is directly related to the overlapping area of the two electrodes. However, to accurately compute the capacitance of the two electrodes, the effects due to the fringing field must be …

Characterizing Unconserved Shallow Wetlands In Lamoure County, North Dakota, Nathan Watson

Scholars Week

Prior to modern agriculture, the plains of North and South Dakota were once a mixed grass prairie with millions of small ponds and wetlands. These wetlands provide summer breeding habitat for countless numbers of migrating bird species. Through the work of conservation organizations and Federal agencies, many of these wetlands have been restored across the Dakotas, Prairie Minnesota, and Iowa. This project focused on locating a county in an area of critical breeding habitat that has had, thus far, limited restoration of these small wetlands and determing their extent and quality using a Geographic Information System (GIS).

Accelerated Structure Formation: The Early Emergence Of Massive Galaxies And Clusters Of Galaxies, Stacy S. Mcgaugh

Faculty Scholarship

Galaxies in the early Universe appear to have grown too big too fast, assembling into massive, monolithic objects more rapidly than anticipated in the hierarchical Lambda cold dark matter (ΛCDM) structure formation paradigm. The available photometric data are consistent with there being a population of massive galaxies that form early (z ≳ 10) and quench rapidly over a short (≲1 Gyr) timescale, consistent with the traditional picture for the evolution of giant elliptical galaxies. Similarly, kinematic observations as a function of redshift show that massive spirals and their scaling relations were in place at early times. Explaining the early emergence …

Turkish Journal of Earth Sciences

We present new radiometric (Ar-Ar) age data from the volcanic rocks occurring in the Eocene strata in the Hekimhan and Gürün-Darende (Malaya) regions. The Eocene units in these regions are represented separately by the Tohma and Darende formations, respectively. The two basaltic volcanic interlayers in the Tohma Formation, occurring in the lower and upper parts of the succession yielded Ar-Ar isochron ages of 51.75±0.76 and 42.66±0.43 Ma, respectively, indicating a deposition age of Ypresian-Lutetian interval for the unit. The andesitic volcanic rocks in the basal parts of the Darende Formation yielded an Ar-Ar isochron age of 37.35±0.72 Ma, revealing that …

The Unfairness Of Fair Machine Learning: Leveling Down And Strict Egalitarianism By Default, Brent Mittelstadt, Sandra Wachter, Chris Russell

Michigan Technology Law Review

In recent years, fairness in machine learning (ML), artificial intelligence (AI), and algorithmic decision-making systems has emerged as a highly active area of research and development. To date, most measures and methods to mitigate bias and improve fairness in algorithmic systems have been built in isolation from policymaking and civil societal contexts and lack serious engagement with philosophical, political, legal, and economic theories of equality and distributive justice. Many current measures define “fairness” in simple terms to mean narrowing gaps in performance or outcomes between demographic groups while preserving as much of the original system’s accuracy as possible. This oversimplified …

The Implications Of Chatgpt For Legal Services And Society, Andrew Perlman

Michigan Technology Law Review

On November 30, 2022, OpenAI released a chatbot called ChatGPT.1 To demonstrate the chatbot’s sophistication and its potential implications, both for legal services and society more generally, most of this paper was generated in about an hour through prompts within ChatGPT. Only this abstract, the preface, the outline headers, the footnotes, the epilogue, and the prompts were written by a person. ChatGPT generated the rest of the text with no human editing. To be clear, the responses generated by ChatGPT were imperfect and at times problematic, and the use of an AI tool for law-related services raises a host of …

Strategies For Articulating Information In Disaster And Emergency Response Common Operating Pictures, Donald Leon Mccue

Walden Dissertations and Doctoral Studies

Emergency management leaders face challenges building common operating pictures (COPs) to display and share critical information, foster collaboration, and improve decision-making among response teams during crises. Without evidence-based strategies to help curb those challenges, poorly implemented COPs can impede situational awareness, decision making, and undermine efforts to get critically needed resources to populations in need. Grounded in a multi-theory model conceptual framework that leveraged the formulation of SA, decision making, and cognitive load psychology, this pragmatic qualitative inquiry explored the strategies that emergency management leaders use to implement the display and sharing of data in COPs to enhance the effectiveness …

Inferring Tlb Configuration With Performance Tools, Cristian Agredo, Tor J. Langehaug, Scott R. Graham

Faculty Publications

Modern computing systems are primarily designed for maximum performance, which inadvertently introduces vulnerabilities at the micro-architecture level. While cache side-channel analysis has received significant attention, other Central Processing Units (CPUs) components like the Translation Lookaside Buffer (TLB) can also be exploited to leak sensitive information. This paper focuses on the TLB, a micro-architecture component that is vulnerable to side-channel attacks. Despite the coarse granularity at the page level, advancements in tools and techniques have made TLB information leakage feasible. The primary goal of this study is not to demonstrate the potential for information leakage from the TLB but to establish …
