Determining K Clusters In K-Means Clustering With The Crab Algorithm, Jasmine Kristine S. Cabrera

Master's Theses

Unsupervised clustering often faces the challenge of determining the correct number of clusters in the absence of a true target variable. Traditional methods such as the Elbow Method and the Silhouette Score can produce ambiguous results and rely on assumptions about cluster shape or separation. To address this, we created the Clustering Rivals and Buddies (CRAB) algorithm which evaluates clusters based on stability across multiple subsamples. CRAB uses pairwise classifications to identify points that consistently group together called “Buddies” and points that remain separated called “Rivals.” Applied with K-means, CRAB accurately recovers underlying cluster structures in both spherical and non-spherical …

The thesis documents the architectural changes required to adapt the verified single-core design into a multicore system, including MMIO-based interrupt support, a shared cache hierarchy with cache-coherence mechanisms, and clock-gated modules. It further presents a …

A History Of The Underground Comix Scene: The Seriousness Of An Unserious Genre, Harris Darcie Shugart

Master's Theses

The Underground Comix Scene of the 1960s and 1970s was born out of an age of censorship. The Comics Code Authority, a regulatory body created by the Comics Magazine Association of America in 1954, established guidelines requiring publishing houses to self-regulate following a recommendation from the United States Senate Subcommittee on Juvenile Delinquency in 1953. Comix with an X, for their X-rated nature, represent an emerging counter-culture in the latter half of the 1960s and the 1970s, with an epicenter of San Francisco. These comix and their artists were not interested in obtaining the looming ‘Seal of Approval’ from the …

The Court Of Small Things, The Curse Of Legal Superstition: The Precipitous Decline Of Small Claims Court, Why It Matters, And What Can Be Done About It, Telia Mary U. Williams

Nevada Law Journal

This Article addresses the precipitous decline of small claims courts in the United States and argues that their erosion is more than administrative; it is a democratic and constitutional crisis. Small claims courts were once the laboratories of everyday justice, where ordinary citizens could access law without lawyers, ritual, or mystery. The seemingly minor disputes of the small claims court illuminate the democratic soul of American law. Yet, over recent decades, filings have declined dramatically, and the locus of power has shifted from the poor to repeat-player institutional actors. This is in part due to what I call, “legal superstition,” …

(R2133) Analysis Of A Bulk Queue With Balking, Adaptive Overloading Service, Multiple Vacation, Inspection And Rework, S. Karpagam, R. Lokesh

Applications and Applied Mathematics: An International Journal (AAM)

We consider a queueing system that utilizes a single server to manage product flow through bulk and overload service modes, depending on queue length. Balking occurs when the queue length reaches ‘N’. After completion of service, products undergo quality inspection, with defective products sent for rework based on specific probabilities. If the product is non-defective, the server continues processing until the queue length exceeds a certain threshold; beyond this point, the server is either routed back to bulk service or directed to an overload service. Also, the server goes into a vacation mode when the queue size is below a …

Rethinking Pakistan Studies: The Grounds Of Regional Knowledge After South Asia, Zoya Sameen

FAS Pakistan

This article rethinks Pakistan Studies as both a pedagogical project and a field of knowledge by examining the limits of history as a tool of legitimation. It argues that in the public sphere, history often serves to authorize the present, and shows how Pakistan Studies has historically operated within this framework. At the same time, the article suggests that this condition opens up another possibility: to understand history not as passive inheritance but as an active demand upon the present. Seen in this light, Pakistan Studies emerges not as a stable body of knowledge but as a series of shifting …

Seqra Developments: Amendments To Ease Housing Construction, Revised Regulations, New Cases, Michael B. Gerrard

Faculty Scholarship

A month before, the New York State Department of Environmental Conservation (DEC) issued regulations on protecting disadvantaged communities, and took steps to require more discussion of climate impacts under SEQRA.

Reforming Funding To Better Defend Families: Holistic Preventive Legal Advocacy That Checks Cps Agency Power, Joshua Gupta-Kagan

Faculty Scholarship

The federal government has provided funds to support legal representation of parents facing allegations of child neglect or abuse since 2019, across administrations of both parties. That funding illustrates the field’s recognition of parent defense’s importance to improving outcomes and reducing harms from the family regulation system, especially once CPS agencies file petitions against parents. Federal Title IV-E funding supports parent representation in those family court cases and for parents at risk of facing such cases. That funding has been an essential boon to parent representation and the benefits that flow from it. It is nonetheless time to take a …

‘Insistent’ Objectors: The (Ab)Use Of Procedural Defenses Before The International Court Of Justice, Damian A. Gonzalez-Salzberg, Eoin Campbell

Michigan Journal of International Law

Procedural defenses refer to tactical devices that object to either a court’s jurisdiction or to the admissibility of an application, aimed at stopping a court from deciding on the merits of a case or, at least, at limiting the scope of its decision. From its creation in June 1945 and up to the end of 2024, the International Court of Justice (“ICJ”) has adjudicated 101 cases, with almost 80% of them featuring procedural defenses raised by states. These defenses have not only been plentiful, but have been extremely effective, leading to the ICJ’s refusal to decide on the merits of …
