Downhole Tools Thermal Shield

Defensive Publications Series

Measurement and Logging While Drilling (M/LWD) tools encounter significant challenges when drilling in high-temperature (HT) oil and gas or geothermal wells. These extreme environments can cause downhole tools to fail and sensors to drift, leading to inaccurate readings and compromising the safety and efficiency of drilling operations. Sensitive electronic components, such as sensors, wiring, and circuit boards, are designed to operate within specific temperature ranges, and prolonged exposure to elevated temperatures can result in malfunction or reduced lifespan.

Secure Decommissioning Of Cloud Resources, Pardha Saradhi Mavilla

Defensive Publications Series

Soft deletion is a feature in cloud computing that provides a safety net against accidental deletions using a predefined grace period within which the cloud resource is recoverable. However, soft deletion creates new operational bottlenecks for users who intended to permanently delete their resources, e.g., continued resource occupation by soft-deleted clouds, inhibited redeployment of resources, etc. This disclosure describes techniques for secure soft deletion of cloud resources in a manner that fulfills operational, security, and user experience requirements such as accelerated decommissioning, visibility into the state of decommissioning, and deterministic rollback of decommissioning. A robust, end-to-end, orchestrated procedure balances resource …

Dynamic Antenna Configuration For Ntn Links Via Predictive Look-Up Table Search, Ali Molaei, Kasra Ghaemi, Gregory Black

Defensive Publications Series

Establishing communication links between mobile terminals, such as smartphones or vehicle communication systems, and non-terrestrial networks (NTNs), for instance, low earth orbit satellite constellations, can be impacted by frequent variations in signal characteristics as satellites move. If a static antenna configuration on a mobile device does not adapt to this dynamic signal environment, link degradation may result. A system for dynamic antenna configuration can use a pre-calculated look-up table (LUT) that maps various satellite positions and signal properties to corresponding antenna tune states. During operation, a predictive algorithm on the terminal can use real-time signal strength measurements and the LUT …

Current Sharing Method For Digital Voltage-Mode Power Converters, Na

Defensive Publications Series

The technology described in this paper relates to a current sharing method for digital voltage-mode power converters connected in parallel. Specifically, the disclosed technology introduces a current sharing loop that calculates the discrepancy between the local output current and the average current of the power stages and adjusts the voltage loop integrator value based on this error. By modifying the integrator state directly, the system enables immediate duty cycle correction without increasing the control system’s order. This approach achieves rapid and stable current sharing within the switching period while maintaining high voltage regulation accuracy without the need for traditional droop …

Framework For Situated Agents Using Tool-Based Perception And Interaction In A Continuous Cognitive Loop, Valentyn Shybanov

Defensive Publications Series

Agentic systems that operate in a transactional or stateless mode can be limited in their ability to perform sustained, multi-step tasks within dynamic digital environments. Such systems may exhibit brittleness, where tool execution failures may lead to a process halting rather than initiating an adaptive recovery. The disclosed technology describes a framework for autonomous agents centered on a continuous perception-cognition-interaction loop. Within this framework, an agent can utilize programmatic tools as sensory inputs to perceive the state of a digital environment and as actuators to effect change, while a cognition layer can process these perceptions to formulate actions. This cyclical …

Understanding Gender Differences In Academic Achievement Among Engineering Students, Luai Al Labadi, Mohammad Saleh Bataineh, Lim Kyuson, Nida Siddiqui

International Journal for Research in Education

In recent years, a noticeable shift has occurred in academic performance, with females consistently outperforming males in mathematical engineering courses. To investigate the factors contributing to this trend, we conducted a comprehensive survey at a main university in UAE. Analyzing data from 431 engineering students, we found that the time spent studying outside the classroom plays a pivotal role, evidenced by a statistically significant p-value of 0.04, contributing to the gender-based performance disparity. Building upon these findings, we propose short-term solutions that instructors and universities can implement promptly to address this issue. This study underscores the importance of ongoing institution-level, …

The Relationship Between Academic Burnout, Passion, Emotional Regulation And Self-Compassion: A Structural Equation Modeling Study, Afaf S. Almohammadi

International Journal for Research in Education

This study aims to investigate the relationship between academic burnout, passion, self-compassion, and emotional regulation using a structural equation model. A total of 630 female postgraduate students participated and completed measures of academic burnout, passion, self-compassion, and emotional regulation scales. The results showed that academic burnout had a significant negative effect on both harmonious and obsessive passion, as well as self-compassion. However, burnout did not significantly affect the two dimensions of emotional regulation (cognitive reappraisal and expressive suppression). Self-compassion played a mediating role between burnout and obsessive passion. Emotional regulation dimensions did not play a mediating role between burnout and …

Enhancing Sustainable Cooling Solutions: Investigating Spot Radiant Cooling Systems Performance And Influence On Indoor Comfort In Hot Climates, Norhane Eldeeb, Ahmed Ahmed Fikry, Abbas Mohamed Elzafarany, Ehab El Shazly, Hinar Abo El-Maged

HBRC Journal

In hot climates, demand for effective sustainable cooling strategies to maintain comfort is high. Nevertheless, conventional radiant cooling systems are often hindered by condensation risks and complex control requirements in partially occupied spaces. To address these challenges, at top inlet conditions of approximately 26°C and 50% Relative Humidity) RH (, three-dimensional CFD simulations validated against the 1.405 kW reference case of Shin et al. were performed to quantify the effect of installation height and panel geometry on spot radiant cooling performance. Lowering the flat CRCP from 2.6 m to 2.2 m reduced volume averaged air temperature (T_a) …
