DyGraph: A Dynamic Graph Generator and Benchmark Suite : NOTES
https://gist.github.com/wolfram77/54c4a14d9ea547183c6c7b3518bf9cd1
There exist a number of dynamic graph generators. Barbasi-Albert model iteratively attach new vertices to pre-exsiting vertices in the graph using preferential attachment (edges to high degree vertices are more likely - rich get richer - Pareto principle). However, graph size increases monotonically, and density of graph keeps increasing (sparsity decreasing).
Gorke's model uses a defined clustering to uniformly add vertices and edges. Purohit's model uses motifs (eg. triangles) to mimick properties of existing dynamic graphs, such as growth rate, structure, and degree distribution. Kronecker graph generators are used to increase size of a given graph, with power-law distribution.
To generate dynamic graphs, we must choose a metric to compare two graphs. Common metrics include diameter, clustering coefficient (modularity?), triangle counting (triangle density?), and degree distribution.
In this paper, the authors propose Dygraph, a dynamic graph generator that uses degree distribution as the only metric. The authors observe that many real-world graphs differ from the power-law distribution at the tail end. To address this issue, they propose binning, where the vertices beyond a certain degree (minDeg = min(deg) s.t. |V(deg)| < H, where H~10 is the number of vertices with a given degree below which are binned) are grouped into bins of degree-width binWidth, max-degree localMax, and number of degrees in bin with at least one vertex binSize (to keep track of sparsity). This helps the authors to generate graphs with a more realistic degree distribution.
The process of generating a dynamic graph is as follows. First the difference between the desired and the current degree distribution is calculated. The authors then create an edge-addition set where each vertex is present as many times as the number of additional incident edges it must recieve. Edges are then created by connecting two vertices randomly from this set, and removing both from the set once connected. Currently, authors reject self-loops and duplicate edges. Removal of edges is done in a similar fashion.
Authors observe that adding edges with power-law properties dominates the execution time, and consider parallelizing DyGraph as part of future work.

Maps2Graphs: A Socially Scalable Method for Generating High-Quality GIS Datas...Tokyo University of Science
GIS -- where Esri is probably the most prominent data provider -- is related to ITS by way of providing ITS research with road maps. Traditionally, GIS data come as .shp files in 2d- or 3dmesh format. The sad news is that (1) even 3dmesh is low resolution, and (2) native GIS roads maps have no context. This study presents a web application which extracts pairwise routes via Google Maps API and stores them in cloud storage (Google Drive, Dropbox, etc.). When done, pairwise routes are merged into the graph ready to use for ITS simulations. The webapp is socially scalable and can use any number of clients, which is important for large datasets.Developing Spatial Applications with Google Maps and CARTO

It highlights platforms like QGIS, GRASS, OpenStreetMap, Ushahidi, and others that enable open mapping and crowdsourced data collection. It addresses criticisms around accuracy and reliability but argues these projects are "good enough" and evolve based on user needs. The document emphasizes that open data and tools allow anyone to engage in mapping and analysis.
CrowdMap: Accurate Reconstruction of Indoor Floor Plan from Crowdsourced Sens...
CrowdMap is a system that uses crowdsourced sensor-rich videos to accurately reconstruct indoor floor plans. It improves upon previous inertial sensor-only methods by leveraging the visual information in videos. The system architecture includes modules for data collection, indoor path modeling, room layout modeling, and floor plan modeling. It is implemented on mobile and cloud platforms and evaluations show it can generate more accurate floor plans than structure from motion techniques. Future work will focus on extracting more context from room panoramas and addressing user incentive and privacy issues.
Mago3D - An innovative AEC/GIS integration platform that can service millions...
This talk was given at the Geospatial World Forum 2018.
This slides introduce a brand new live 3D geo-platform called mago3D that can integrate BIM/AEC(Architecture, Engineering, Construction) and 3D GIS in a web browser. mago3D can manage and visualize millions of 3D objects from different sources in a web browser without installing any plugin or ActiveX. 2 main cores of mago3D are mago3D.js and F4D format. mago3D.js is a set of JavaScript that expands existing WebGL Globe's functionality and usability. mago3D.js increases rendering quality and speed. mago3D.js runs on top of AGI's Cesium.js and NASA Web World Wind at the moment. One of big hurdle to integrate AEC and 3D GIS simultaneously is handling and visualizing the massive 3D objects. To overcome this hurdle, new format called F4D has been devised. F4D is a sort of 3D service format that contains LOD, pre-processed occlusion culling information, and visibility indexes. Currently industry standard IFC(Industry Foundation Classes), JT(Jupiter Tessellation), and popular 3D formats such as OBJ, 3DS, COLLADA DAE can be converted to F4D format. mago3D has been successfully used in several industries including ship building, FM(Facility Management), constructions so far. Real success story of mago3D will be presented during the talk.

A tech writer, a map, and an app
The document discusses the development of a web and mobile app called "Tech Comm on a Map" that maps events and resources related to technical communication. Key points:
- The app allows users to contribute tech comm events and resources through a web form or Android app, which are stored in a Google Sheet and displayed on an interactive map using the Google Maps API.
- The web app was created using HTML, CSS, JavaScript and jQuery. Data is retrieved from Google Sheets using Apps Script.
- An Android version was also developed using Java and the Google Maps Android API to make the map accessible on mobile.
- The project is open source on GitHub and the developer discusses lessons learned around community collaboration and

Odoo ERP Vs. Traditional ERP Systems – A Comparative Analysis
When it is all about ERP solutions, companies typically meet their needs with common ERP solutions like SAP, Oracle, and Microsoft Dynamics. These big players have demonstrated that ERP systems can be either simple or highly comprehensive. This remains true today, but there are new factors to consider, including a promising new contender in the market that’s Odoo. This blog compares Odoo ERP with traditional ERP systems and explains why many companies now see Odoo ERP as the best choice.
What are ERP Systems?
An ERP, or Enterprise Resource Planning, system provides your company with valuable information to help you make better decisions and boost your ROI. You should choose an ERP system based on your company’s specific needs. For instance, if you run a manufacturing or retail business, you will need an ERP system that efficiently manages inventory. A consulting firm, on the other hand, would benefit from an ERP system that enhances daily operations. Similarly, eCommerce stores would select an ERP system tailored to their needs.
Because different businesses have different requirements, ERP system functionalities can vary. Among the various ERP systems available, Odoo ERP is considered one of the best in the ERp market with more than 12 million global users today.
Odoo is an open-source ERP system initially designed for small to medium-sized businesses but now suitable for a wide range of companies. Odoo offers a scalable and configurable point-of-sale management solution and allows you to create customised modules for specific industries. Odoo is gaining more popularity because it is built in a way that allows easy customisation, has a user-friendly interface, and is affordable. Here, you will cover the main differences and get to know why Odoo is gaining attention despite the many other ERP systems available in the market.

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.
