This document discusses SWARM, a modular spacecraft design project. SWARM modules are capable of self-assembly and reconfiguration using wireless communication. Each module has common components like a structural package, power supply, and sensors. The interface allows modules to autonomously dock and undock, transfer mechanical and electrical loads, and communicate data wirelessly. The current interface design was tested and works well for docking, but future work includes adding fluid transfer and improving docking sensors. SWARM demonstrates the potential for reconfigurable spacecraft using standardized modular components.

Module Level Power Regulation
This document discusses module-level power electronics (MLPE) and a new distributed parallel MLPE power regulation topology called tenK. It notes that annual MLPE installations are expected to grow significantly by 2020 according to research firms. The tenK topology utilizes modular, low-cost components to create an easy to install, highly reliable, zero maintenance PV system. Key aspects of tenK include modules that have redundant power controllers and a parallel DC bus connecting groups of inverters. This approach aims to improve system longevity and allow energy from any solar cell to be inverted despite failures.

This presentation summarizes the June 2007 anomaly where all six Russian Segment computers on the International Space Station shut down. It describes the timeline of events, impact to ISS operations, and temporary mitigation steps taken. The root cause was determined to be moisture contamination in the BOK3 command unit that provided commands to the computers. Design changes were implemented to improve redundancy, including separating redundant systems beyond the influence of single failures and ensuring systems are designed to fail safely.

Data link layer
This document summarizes a presentation on data link layer protocols and MAC. It discusses the data link layer overview, properties, functions and services, protocols like HDLC and Ethernet, error detection using CRC, and flow control protocols like stop-and-wait and sliding window. Examples of CRC calculation and the sliding window protocol are shown. The presentation was given by Mr. V. Kovendan at Arasu Engineering College on data link layer protocols and MAC sublayer functions.
ORBCOMM Satellite System
The ORBCOMM system provides global asset monitoring and messaging using a constellation of low Earth orbit satellites and ground infrastructure. It consists of 36 operational satellites in low Earth orbit, a network of gateways and their earth stations, and subscriber communicators. The satellites use TDMA and QPSK to communicate with the gateways and subscribers. The gateways process messages and provide connectivity to the public switched telephone network. This allows the system to offer positioning, messaging and monitoring services on a global scale.
Senior Design Project "Space-Based Solar Power System"
The document summarizes the design of a space-based solar power system. It proposes using five satellites in geosynchronous orbit to collect and transmit solar power to five ground stations via microwave beams. Each satellite would have a large solar concentrating structure and transmitter to beam 1 GW of power to Earth. The design aims to meet requirements to transmit 1 GW of power by 2040 for under $21 billion.
Random access scan
This document discusses limitations of traditional serial scan design for testing integrated circuits and proposes an alternative called Random Access Scan (RAS). RAS addresses three key limitations of serial scan: 1) test data volume, 2) test application time, and 3) test power. In RAS, flip-flops act as addressable memory elements during test mode, reducing time to set and observe flip-flop states compared to serial scan. While RAS requires more gates and test pins than serial scan, it significantly reduces switching activity and power consumption during testing.

Nextronex has developed a new distributed solar inverter and wiring system that improves on traditional centralized designs. Their system uses low profile inverters placed throughout the solar array, connected by an integrated DC bus and zone boxes, to minimize voltage drops and copper use. This distributed architecture provides improved efficiency, fault tolerance, monitoring and maintenance capabilities compared to conventional large central inverters. Nextronex has also developed smart switching and control algorithms to optimize inverter-level efficiencies and response to changing conditions.

We describe the experiment that was carried out to communicate a Mobile Platform and a Ground Station through a Medium Earth Orbit (MEO) satellite. The physical layer in both ends, based on the specifications of the Satellite Component of the Universal Mobile Telecommunications System (S-UMTS), was implemented using Software Defined Radio (SDR) technology. The Mobile Terminal was boarded in both an unmanned aerial vehicle (UAV) and a car for the field trials. The ultimate goal was to test the practical performance of different physical layer adaptive techniques in the return link, and evaluate the open loop signal to noise ratio (SNR) contribution to the link adaptation algorithms.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

5th LF Energy Power Grid Model Meet-up Slides
5th Power Grid Model Meet-up
It is with great pleasure that we extend to you an invitation to the 5th Power Grid Model Meet-up, scheduled for 6th June 2024. This event will adopt a hybrid format, allowing participants to join us either through an online Mircosoft Teams session or in person at TU/e located at Den Dolech 2, Eindhoven, Netherlands. The meet-up will be hosted by Eindhoven University of Technology (TU/e), a research university specializing in engineering science & technology.
Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.
