Nature Communications, Published online: 10 June 2026; doi:10.1038/s41467-026-74374-5 This study presents a framework that detects and countermeasures false data injection attacks in multi-area power systems, improving state estimation, reducing false alarms and stabilizing grid frequency under noisy and disturbed conditions.

The Applied Research Laboratory at Penn State has named Martin Irvine Jr. as deputy director and head of its Undersea Systems Office. In this role, Irvine will guide the laboratory’s long-term vision and research roadmap for undersea dominance, providing strategic, technical and operational leadership to a multidisciplinary team focused on addressing the nation’s most critical undersea challenges.

The Smart Systems Integration Lab at Penn State York is preparing students to tackle real-world engineering challenges through research focused on transportation and smart city technologies.

I helped redesign a large BigQuery-based enterprise data warehouse and cut spend by 57%. The biggest savings didn't come from dashboards or one-off query tuning. They came from architecture decisions — partitioning, clustering, incremental MERGE patterns, and a better capacity model. Here's how I approach cost as an architectural problem in large systems. The Problem I joined as the Solution Arch…

The difference between a supply chain integration run with synchronous REST API calls and a data flow based on an asynchronous, Transactional Outbox architecture is the difference between the production line stopping or keeping on running. In classic monolithic structures or hastily written microservices, sending an HTTP POST request to an external supplier system and waiting for a "200 OK" is th…

A new imaging framework improves how unmanned aerial vehicle (UAV) radar systems reconstruct three-dimensional (3D) scenes in complex urban environments. By combining three-dimensional back projection with compressive sensing, the method overcomes a long-standing low-altitude imaging problem known as channel migration. The result is more accurate 3D reconstruction of buildings and ground features…

The Art of Influence: A Practical Guide to Soft Skills and Collaboration for Engineers The Art of Influence: A Practical Guide to Soft Skills and Collaboration for Engineers Engineering excellence isn’t built on code alone. It hinges on how well teammates communicate, negotiate trade-offs, and align around shared goals. This guide focuses on concrete, repeatable soft skills and collaboration prac…

Say you want to upgrade your laptop's RAM, what's the first thing you do if you have a new RAM stick in your hand? Turn off the laptop, install the new RAM, and restart. Pretty easy? Now imagine you're a system engineer at Amazon AWS. You are asked to upgrade the RAM of a physical machine, but it got some virtual machines running on it, what would you do? If you stop the server even for a second,…

_Smart Infrastructure Data Systems Review_. 2024Smart infrastructure systems combine power-grid sensors, traffic counters, building controllers, weather feeds, maintenance logs, and public-service data into continuously changing operational streams. These systems require more than high-throughput ingestion: they need low-latency anomaly detection, reliable forecasting, cross-source evidence linki…

No team. No budget. Just Go. This is the engineering deep dive behind pastaay, a chaos engine that breaks everything from HTTP headers to physical memory. 1. Why This Exists I started this project with a simple question: why do all chaos engineering tools stop at the network? Netflix’s Chaos Monkey kills instances. That’s useful if your failure mode is “pod died.” Gremlin adds CPU spikes. Litmus …

This note proposes a systems-theoretic constraint on long-horizon regulation. While classical cybernetics emphasizes informational adequacy and feedback responsiveness, the present argument focuses on the temporal admissibility of optimization itself. The paper formulates the Optimization Horizon Mismatch Principle: when the optimization horizon of a regulator is structurally shorter than the sta…

The PID controller is the workhorse of industrial control. It runs temperature loops, motor drives, flow valves, and flight surfaces. The algorithm itself is three terms and a line of arithmetic. The hard part has never been the controller — it is choosing the three gains. Set them too low and the system crawls toward its target. Set them too high and it oscillates, or worse, runs away. "Tuning" …

Engineer token-efficient, self-adapting workflows for production The post From Prototype to Profit: Solving the Agentic Token-Burn Problem appeared first on Towards Data Science .

Every serious infrastructure investment goes into redundant hardware, distributed systems, and multi-region failover. Almost none goes into the one dependency that sits above all of it — the small number of engineers whose departure, unavailability, or burnout makes the environment unrecoverable. The infrastructure bus factor is the organizational single point of failure that no architecture revi…

Part 2 of 7 — The Mac Kubernetes Lab: A Production-Mirror Setup from Scratch. Previously in Part 1: I walked through why I replaced Multipass with OrbStack, the dual-cluster architecture I settled on, and a preview of the M1 vs M4 CNI problem that’s coming in Part 4. The cluster I am going to set up in this article is the one I spend most of my working day inside. It’s a single-node Kubernetes cl…

Author: Rajendra Acharya . Why Proxmox and Ceph? Proxmox Virtual Environment (PVE) is a powerful, open-source platform for managing virtual machines and containers. Combined with Ceph, a distributed storage system, you can achieve: High Availability (HA): Minimized downtime with automatic failover. Scalability: Seamless expansion of compute and storage resources. Cost-Effectiveness: Open-source a…

The Problem Setting up a SCADA system for a small water treatment plant or solar farm usually means: Spending $10K-$50K on software licenses Dedicating a Windows server Hiring a specialist for weeks of configuration Ongoing maintenance fees What if you could just open a file in your browser?

Why I Built a Free SCADA Alternative Commercial SCADA systems are insanely expensive: Wonderware (AVEVA): $25,000+ license Ignition: $4,000-$50,000/year WinCC (Siemens): $15,000+ Windows-only For small water treatment plants, solar farms, or educational labs this is overkill.

_Cyber-Physical Grid Intelligence Forum_. 2026Wide-area power-grid observability depends on phasor measurement unit (PMU) streams, calibration-aware instrumentation, and fast operator workflows, but the analytic stack that joins these elements is often split between stream processors, model-serving systems, privacy filters, and manual maintenance queues. This paper proposes Self-Governing Grid In…

Engineering researchers at North Carolina State University have developed a mathematical framework that can be used to help hunger-relief organizations get food to households that need it more efficiently than conventional methods.
