Fault Tolerant Adaptive Control Under Actuator Saturation For Robot Manipulators, D. J. López-Araujo, N. Alvarez-Jarquin, P. Borja, A. T. Becker

School of Engineering, Computing and Mathematics

In practice, actuators inherently have natural limitations that are often overlooked by theoretical control strategies, such as bounded output and discrepancies between calculated and actual responses. Consequently, reliable control techniques must be employed to ensure safe and dependable operation. We propose an adaptive control law for global regulation in the case of partial loss of effectiveness due to input faults. The proposed control strategy maintains the system at the desired configuration while accounting for the physical limitations of the actuators. Additionally, it is suitable for dealing with unknown parameters in the vector of gravitational forces, making it robust to these …

State-Dependent Queueing For Adaptive Signal Control: A Simulation-Based Performance Evaluation, Shaimaa Alseddiek, Usama Elrawy Shahdah, Hala B. Nafea, Hossam El-Din Moustafa, El-Said Ahmed Marzouk, Mohamed M. Ashour

Mansoura Engineering Journal

Urban traffic congestion persists as a critical challenge to transportation system efficiency, sustainability, and safety. Traditional queuing models utilizing fixed service rates inadequately represent the dynamic feedback between congestion and capacity in real vehicular flow. State-Dependent Queuing Models (SDQMs) address this limitation by modelling service rate as a function of queue length or density. This research advances SDQM application for adaptive traffic signal control through development of a calibrated state-dependent departure rate implemented within a microscopic simulation environment using SUMO and TraCI. Six control strategies including fixed-time, actuated, and two SDQM variants were evaluated across traffic demands ranging from undersaturated …

Rethinking The Fund Termination Sanction, Samuel R. Bagenstos

Articles

Title VI of the Civil Rights Act of 1964 is often referred to as the “sleeping giant” of civil rights law. It is a “giant” because it prohibits any form of race discrimination engaged in by any recipient of federal financial assistance, and because the remedy set forth in the statute for a violation is the termination of federal funds. And it is “sleeping” because, except for a brief moment during the desegregation era, the federal government had never seriously attempted to terminate a recipient’s federal grants for a violation of the statute. Nor had the federal government seriously attempted …

What's The Point Of Reparation?, Daniel Fryer

Articles

Despite its ancient history in philosophical and legal thought, importance to progressive social movements, and relative simplicity as a notion of fairness—if you break something, you ought to fix it—reparative justice is largely misunderstood. This is problematic given increasing calls for reparation from historically disadvantaged groups. Rather than assessing the validity of these claims, this Article addresses a fundamentally antecedent issue: what’s the point of reparation? Rejecting arguments that claim reparation is about compensation, supplementing distributive justice, and reconciliation, I argue that the point of reparation is to repair unjust social relations created by past wrongdoing. The relational theory of …

From Relic To Relevance, The Resurgence Of Tariffs, Reuven S. Avi-Yonah

Articles

Modern legal scholarship has largely relegated tariffs to economic analysis, overlooking their legal and policy significance. This Article challenges that view by examining tariffs as a potential pillar of fiscal policy, exploring their viability as a revenue source alongside or in place of traditional income and corporate taxation. While historically central to U.S. government funding, tariffs’ importance diminished with the rise of income taxation and trade liberalization. However, their recent resurgence as a tool for trade protection raises broader questions about their role in national economic strategy.

This Article critically assesses the feasibility of a tariff-based tax system, drawing on …
