Epic of the palm tree in Los Angeles
No full textThesis: M. Arch., Massachusetts Institute of Technology, Department of Architecture, 2018.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 84-85).The Palm Tree of Los Angeles is it's own entity. It is spelled with a capital P and T. It is also inherently contranymic. (A contranym is defined as a word with two opposite meanings.) Although referred to as "tree," it biologically is not. It is a monocot, similar to grass. Although it is completely embedded into the making of Los Angeles, it is not native to the city at all. Different palm trees from around the world, along with their stories, have participated in constructing myths continuously perpetuated in and by Los Angeles. Current myth making, however, perpetuates a flat, simple narrative. This thesis brings multiple dimensions of positive and negative narratives forward in one continual experience, collapsing these into an alternative mythology. The proposal moves from a flat representation to a collapsed representation. Flat representation is when the myth references only a single story, whereas collapsed representation allows the myth to reference multiple stories. This shift is a new approach on reading the city's history, creating an alternative mythology. By using an aesthetic of Persian miniatures, the thesis re-orientalizes representations of the palm tree. I use the term re-orientalize intentionally, also calling to a re-orienting of the interpreter. This thesis uses a flat aesthetic, but tells a collapsed mythology. The proposal is architecturalized through a series of interventions in the city that can be approached either on their own, or as a constructed loop. The series of interventions are put together as a "nameh," which is a book from a Persian tradition that tells a type of history through painting and verse. This is the Palmnameh: The Epic of The Palm.by Alaa Quraishi.M. Arch
FRSH: A Frugal and Rapid bioSensor for in-House use to assess meat spoilage
No full textBiogenic amines (BAs) represent a toxicological risk in many food products. Putrescine is the most common BAs found in food and is frequently used as a marker for food quality. Today there is a lack of regulation concerning safe putrescine limits in food as well as outdated food handling practices leading to unnecessary putrescine intake. Conventional methods used to evaluate BAs in food are generally time and resource heavy, limiting the options for on-site analysis. In this work, we developed a transcription-factor based biosensor for quantification of putrescine, one of the BAs in meat products, using a naturally occurring putrescine responsive repressor-operator pair (PuuR-puuO) from Escherichia coli. Moreover, we demonstrate the use of the putrescine biosensor with a paper-based cell-free device that enables low-cost and rapid putrescine detection. The system was validated using a variety of consumer meat samples with comparable performance to standard well-plate analysis methods. We propose that our system is ready for use to assess the safety of meat products will contribute to a new phase of low-cost biosensors designed for food safety

Learning-Based Approaches for Optimal Control and Resilient Operation of Battery Energy Storage Systems in Cyber-Physical Environments
No full textThe increasing deployment of Battery Energy Storage Systems (BESS) is transforming modern power grids by providing essential support for the integration of renewable energy sources, enhancing grid stability, and enabling more efficient energy management. As BESS become more widespread, they are required to perform complex functions, such as balancing supply and demand, regulating voltage, and managing frequency fluctuations. However, these advanced roles introduce significant challenges, ensuring that BESS operate optimally under varying conditions and in the face of growing cybersecurity threats. Additionally, the accurate estimation of the State of Health (SoH) of BESS is critical for maintaining their long-term performance and preventing costly failures. This thesis aims to address these multifaceted challenges by developing and integrating innovative strategies that optimize BESS control, fortify their cybersecurity, and improve SoH estimation. By leveraging learning-based technologies such as deep reinforcement learning (DRL), meta-learning, and machine learning, this research aims to push the boundaries of BESS capabilities, ensuring they remain reliable, efficient, and secure as they become increasingly integral to the future energy landscape.
The first major contribution of this thesis is the development of a DRL framework tailored for the adaptive and robust control of BESS. This framework addresses the dynamic complexities and uncertainties inherent in BESS operations, outperforming traditional gradient-based methods in optimizing system performance under various operational scenarios. A hierarchical DRL approach is introduced, ensuring that BESS can effectively manage their dynamic behavior while maintaining safe and efficient operations across diverse conditions.
The second contribution is the introduction of a DRL-inspired Growth Meta-heuristic Optimizer, designed in the form of a meta-learning algorithm for multi-objective optimization within Cyber-Physical-Social Systems (CPSS). This novel optimizer is capable of learning from prior optimization tasks, improving its performance over time. It effectively balances conflicting objectives, adheres to operational constraints, and significantly enhances overall system performance. Extensive simulations demonstrate the practical utility of this meta-learning optimizer in real-world energy management scenarios, highlighting its superiority over existing methods.
Addressing the increasing cybersecurity threats posed to BESS, the third contribution of this thesis focuses on the development of a comprehensive framework for detecting and mitigating DRL-based cyber-attacks. As energy systems become more digitalized and interconnected, safeguarding BESS from these sophisticated threats is critical to maintaining their integrity and reliable operation. This framework provides a robust defense mechanism, ensuring that BESS can continue to operate securely within CPSS.
Finally, this thesis advances the field of SoH estimation for BESS by employing vision transformers and Gaussian process models. This approach offers a highly accurate and reliable method for monitoring battery health over time, which is crucial for extending the lifespan and improving the efficiency of BESS.
Through the integration of these methodologies, this thesis provides a comprehensive solution to the pressing challenges faced by BESS in modern power systems. The research contributes significantly to the development of resilient, efficient, and secure energy storage systems, supporting the sustainable evolution of the energy landscape
English-Arabic Cultural Effect in Translation: A Relevance Theory Perspective
No full textThis article is co-authored with Prof. Alaa Eddin Hussain.
Monograph. Original workThis study is framed within a competence-oriented model which provides the
target text (TT) receiver with communicative clues. These clues allow inference to be optimally
captured. Hence, this approach looks at translation as an example of communication mainly
based on the cost and effect model of inferencing and interpretations. Strategies adopted in
this paper are determined by context-specific consideration of relevance, with special
reference to cultural aspects. Applied to translation, one of the most appropriate strategies
is to re-produce the cognitive effect intended by the source text (ST) communicator with the
lowest possible effort on the part of the TT receiver. This study concludes that when there is a
lack of isomorphism or symmetry between the cultural contents of the two languages, the
translator will have to opt for content-cognitive effect or cultural transplantation. The
translator would have to assess the relevance of content and form in a specific context in order
to achieve the same effect in the TT. It has been emphasized, however, that translation as a
special instance of human communication leads to the conclusion that various methods may be
justified in their own right, if we take into consideration the differences in the text-types, the
intention of the author, readership, and the purpose of translation. In a nutshell, however,
translation remains a craft which requires not just training and skill but also continually
renewed linguistic and non-linguistic knowledge, considerable imagination as well as
intelligence and common sense, and most of all talent
