Modified Gradient Based Iterative Algorithm For Solving The Generalized Sylvester-Conjugate Matrix Equation Over Generalized Centro-Symmetric Matrices, Naglaa M. El-Shazly, Mohamed A. Ramadan, Marwa H. El-Sharway

Al-Azhar Bulletin of Science

We have recently established two techniques of relaxed gradient based form in order to solve the generalized Sylvester-conjugate matrix problem through centrosymmetric as well as the centro-Hermitian matrices. The major target of this paper is to construct a new iterative strategy to obtain the solution of the aforementioned matrix equation through generalized centro-symmetric matrices by applying a modulated method of gradient based form. The performance of our proposed technique is compared to that the iterative algorithm of the relaxed gradient based form over centrosymmetric matrices. To confirm that our constructed technique is convergent, we set up some conditions. Finally, we …

Duality In Contract And Tort, Tim Friehe, Joshua C. Teitelbaum

Georgetown Law Faculty Publications and Other Works

We study situations in which a single investment serves the dual role of increasing the expected value of a contract (a reliance investment) and reducing the expected harm of a post-performance accident (a care investment). We show that failing to account for the duality of the investment leads to inefficient damages for breach of contract and inefficient standards for due care in tort. Conversely, we show that accounting for the duality yields contract damage measures and tort liability rules that provide correct incentives for efficient breach and reliance in contract and for efficient care in tort.

Oxider To Fuel Ratio Shift Compensation Via Vortex Strength Control In Hybrid Rocket Motors, Max W. Francom

All Graduate Theses and Dissertations, Fall 2023 to Present

Hybrid motors have existed as a hypothetical propulsion system for decades in a wide range of upper stage rocket motors due to their simple, robust, non-toxic, and versatile nature. However, inherent to hybrids is Oxidizer to Fuel ratio (O/F) shift over time, which results in performance losses for the majority of the rocket’s lifetime. The purpose of this study is to develop a hybrid rocket motor capable of manipulating O/F at will, resulting in an engine which eliminates the undesirable effects of O/F shift.

Ur2m: Uncertainty And Resource-Aware Event Detection On Microcontrollers, Hong Jia, Young D. Kwon, Dong Ma, Nhat Pham, Lorena Qendro, Tam Vu, Cecilia Mascolo

Research Collection School Of Computing and Information Systems

Traditional machine learning techniques are prone to generating inaccurate predictions when confronted with shifts in the distribution of data between the training and testing phases. This vulnerability can lead to severe consequences, especially in applications such as mobile healthcare. Uncertainty estimation has the potential to mitigate this issue by assessing the reliability of a model's output. However, existing uncertainty estimation techniques often require substantial computational resources and memory, making them impractical for implementation on microcontrollers (MCUs). This limitation hinders the feasibility of many important on-device wearable event detection (WED) applications, such as heart attack detection. In this paper, we present …

Strategy For Predictive Control Of The Rectification Process Based On A Model Controller With A Given Forecast, Ildar Rafkatovich Sultanov

Chemical Technology, Control and Management

A method is being developed to optimize the generated controls for the multicomponent distillation process with prediction, based on predictive data with a moving horizon. The difference between this method and the classical modeling approach, in which the percentage of the degree of opening of valves installed on the output streams of the column is used as control actions, is that control occurs on the feedback principle. The proposed method is based on the use of a dynamic process model to optimize control actions in real time in order to achieve certain production targets. The essence of the MPC approach …

Justice, Inclusion, And Incentives, Ghislain Herman Demeze-Jouatsa, Roland Pongou, Jean-Baptiste Tondji

Economics and Finance Faculty Publications and Presentations

How does justice affect individual incentives and efficiency in a political economy? We show that elementary principles of distributive justice guarantee the existence of a self-enforcing contract whereby agents non-cooperatively choose their inputs and derive utility from their pay. Chief among these principles is that your pay should not depend on your name, and a more productive individual should not earn less. We generalize our analysis to incorporate inclusivity, ensuring basic pay to unproductive agents, implemented through progressive taxation and redistribution. Our findings show that without redistribution, any self-enforcing agreement may be inefficient, but a minimal level of redistribution guarantees …

Coordinated And Uncoordinated Punishment In A Team Investment Game, Vicente Calabuig, Natalia Jiménez-Jiménez, Gonzalo Olcina, Ismael Rodriguez-Lara

ESI Publications

Coordinated punishment occurs when punishment requires a specific number of punishers to be effective, otherwise, no damage will be inflicted on the target. While societies often rely on this punishment device, its benefits are unclear compared to uncoordinated punishment, where punishment decisions are substitutes. In this paper, we compare the efficacy of coordinated and uncoordinated punishment in a team investment game with two investors and one allocator. Our findings indicate that coordinated punishment results in higher levels of cooperation and reciprocity, as measured by the levels of joint investment and the return by allocators. Importantly, this does not translate into …

A Multi-Method Examination Of Donor Overhead Aversion: Implications For Marketing A Cause, Devin Lunt, Ryan E. Freling, Lucas D. Lunt

Atlantic Marketing Journal

Overhead aversion refers to a reluctance among donors to contribute to a charitable cause when a portion of that donation is allocated to non-cause-related costs. As a consequence, there is an impact on donor intentions and behaviors. A meta-analysis shows that characteristics of potential donors and the charitable cause moderate the impact of overhead level on donation intentions and behaviors. A follow-up experiment investigates two potential mechanisms underlying overhead aversion: perceived personal impact and perceived efficiency. Results of a survey experiment suggest the negative influence of overhead costs on donative behaviors is exacerbated when potential donors doubt their ability …

Last-Minute Coordination: Adapting To Demand To Support Last-Mile Operations, Kedong Chen, Hung-Chung Su, Kevin Linderman, William Li

Information Technology & Decision Sciences Faculty Publications

In the highly competitive e-commerce industry, customer-facing warehouses are crucial as the “order penetration points” for e-commerce last-mile operations. This research examines how warehouses use last-minute coordination, an unstructured mechanism, to ensure sufficient inventory at the order penetration points. Previous research has focused on structured mechanisms like contracts and inventory management systems to enhance warehouse performance. However, these mechanisms can be ineffective when faced with unforeseen local contingencies. To adjust inventory and adapt to changes in supply and/or demand, warehouses need to engage in unstructured, last-minute coordination with other warehouses. Using coordination and loose coupling theories, we find that coordinating …

Race: An Efficient Redundancy-Aware Accelerator For Dynamic Graph Neural Network, Hui Yu, Yu Zhang, Jin Zhao, Yujian Liao, Zhiying Huang, Donghao He, Lin Gu, Hai Jin, Xiaofei Liao, Haikun Liu, Bingsheng He, Jianhui Yue

Michigan Tech Publications, Part 2

Dynamic Graph Neural Network (DGNN) has recently attracted a significant amount of research attention from various domains, because most real-world graphs are inherently dynamic. Despite many research efforts, for DGNN, existing hardware/software solutions still suffer significantly from redundant computation and memory access overhead, because they need to irregularly access and recompute all graph data of each graph snapshot. To address these issues, we propose an efficient redundancy-aware accelerator, RACE, which enables energy-efficient execution of DGNN models. Specifically, we propose a redundancy-aware incremental execution approach into the accelerator design for DGNN to instantly achieve the output features of the latest graph …

Formalism In Contract Exposition, Gregory Klass

Georgetown Law Faculty Publications and Other Works

Formalism in contract law has had many defenders and many critics. What lawmakers need, however, is an account of when formalist approaches work and when they do not. This article addresses that need by providing general theory of the rules of contract interpretation and construction and identifying several ways those rules can be more or less formalist. The theory draws from legal philosophy, the philosophy of language, economic contracts scholarship, and caselaw.

The result is a distinction between two forms of formalism in contract law. Formalities effect legal change by virtue of their form alone, thereby obviating interpretation. Examples from …

Convergence By Design: Who Contracts And The Plural Purposes Of Contract Law, Gregory Klass

Georgetown Law Faculty Publications and Other Works

A theory is robustly pluralist if it maintains that law is justified by multiple independent nonordered principles. Some have argued that robustly pluralist theories are deficient because they can provide no practical guidance when those principles conflict. The objection is misplaced when applied to pluralist theories of contract law.

This article demonstrates the possibility of a robustly pluralist and practically relevant theory of contract law by modeling a multipurpose law of contract. Five simple models are constructed to illustrate several purposes a contract law might serve, depending on preferences of the populace (self-interested utility maximizers, a preference for sharing, a …
