The Life Cycle of a Massive Activation: Stochastic Birth, Weight-Decay-Driven Growth, and Competitive Consolidation
S. Aaron McClendon, Jorge Gallego-Feliciano, Antonios Saravanos
Massive activations, residual-stream coordinates with magnitudes far larger than typical activations, are associated with attention sinks in transformers, but how their scale is re…
Global drivers and barriers to the public acceptance of autonomous vehicles: Evidence from 17 countries
Antonios Saravanos
This study investigated the public acceptance of Society of Automotive Engineers Level 3 conditionally automated cars, which can self-drive under certain specified conditions but r…
Three Roles, One Model: Role Orchestration at Inference Time to Close the Performance Gap Between Small and Large Agents
S. Aaron McClendon, Jorge Gallego-Feliciano, Stavros Zervoudakis +1
Large language model (LLM) agents show promise on realistic tool-use tasks, but deploying capable agents on modest hardware remains challenging. We study whether inference-time sca…
The Opaque Pointer Design Pattern in Python: Towards a Pythonic PIMPL for Modularity, Encapsulation, and Stability
Antonios Saravanos, John Pazarzis, Stavros Zervoudakis +1
Python libraries often need to maintain a stable public API even as internal implementations evolve, gain new backends, or depend on heavy optional libraries. In Python, where inte…
A Brief History of the Waterfall Model: Past, Present, and Future
Antonios Saravanos
The waterfall model, one of the earliest software development methodologies, has played a foundational role in shaping contemporary software engineering practices. This paper provi…
Hidden Dynamics of Massive Activations in Transformer Training
Jorge Gallego-Feliciano, S. Aaron McClendon, Juan Morinelli +2
We present the first comprehensive analysis of massive activation development throughout transformer training, using the Pythia model family as our testbed, and release our full da…
Waterfall Model Simulation: A Systematic Mapping Study
Antonios Saravanos
This paper systematically maps peer-reviewed research and graduate theses/dissertations that explicitly simulate the waterfall model. Following Petersen's mapping guidelines and Ki…
How Warm-Glow Alters the Usability of Technology
Antonios Saravanos
As technology increasingly aligns with users' personal values, traditional models of usability, focused on functionality and specifically effectiveness, efficiency, and satisfactio…
Gauging Public Acceptance of Conditionally Automated Vehicles in the United States
Antonios Saravanos, Eleftheria K. Pissadaki, Wayne S. Singh +1
Public acceptance of conditionally automated vehicles is a crucial step in the realization of smart cities. Prior research in Europe has shown that the factors of hedonic motivatio…
Simulating the Software Development Lifecycle: The Waterfall Model
Antonios Saravanos, Matthew X. Curinga
This study employs a simulation-based approach, adapting the waterfall model, to provide estimates for software project and individual phase completion times. Additionally, it pinp…
The Effect of Warm-Glow on User Behavioral Intention to Adopt Technology: Extending the UTAUT2 Model
Antonios Saravanos, Neil Stott, Dongnanzi Zheng +1
In this study, we enhance the Unified Theory of Acceptance and Use of Technology (UTAUT2) by incorporating the warm-glow phenomenon to clarify its impact on user decisions regardin…
Reputation, Risk, and Trust on User Adoption of Internet Search Engines: The Case of DuckDuckGo
Antonios Saravanos, Stavros Zervoudakis, Dongnanzi Zheng +7
This paper investigates the determinants of end-user adoption of the DuckDuckGo search engine coupling the standard UTAUT model with factors to reflect reputation, risk, and trust.…
Investigating End-user Acceptance of Last-mile Delivery by Autonomous Vehicles in the United States
Antonios Saravanos, Olivia Verni, Ian Moore +7
This paper investigates the end-user acceptance of last-mile delivery carried out by autonomous vehicles within the United States. A total of 296 participants were presented with i…
Extending the Technology Acceptance Model 3 to Incorporate the Phenomenon of Warm-Glow
Antonios Saravanos, Stavros Zervoudakis, Dongnanzi Zheng
In this paper, we extend the third evolution of the Technology Acceptance Model (TAM3) to incorporate warm-glow with the aim of understanding the role this phenomenon plays on user…
Measuring Consumer Perceived Warm-Glow for Technology Adoption Modeling
Antonios Saravanos, Dongnanzi Zheng, Stavros Zervoudakis
In this paper, we adapt and validate two constructs-perceived extrinsic warm-glow (PEWG) and perceived intrinsic warm-glow (PIWG)-to measure the two dimensions of consumer perceive…
Exploring the Effect of Resolution on the Usability of Locimetric Authentication
Antonios Saravanos, Dongnanzi Zheng, Stavros Zervoudakis +1
Locimetric authentication is a form of graphical authentication in which users validate their identity by selecting predetermined points on a predetermined image. Its primary advan…
The Hidden Cost of Using Amazon Mechanical Turk for Research
Antonios Saravanos, Stavros Zervoudakis, Dongnanzi Zheng +3
In this study, we investigate the attentiveness exhibited by participants sourced through Amazon Mechanical Turk (MTurk), thereby discovering a significant level of inattentiveness…
