CTT2.0 Carbon Track and Trace presentation for SmartCitiesIndiaExpo May 2016 in Delhi and presentation to interested partners. Overview of the project, aims, approaches, technologies used to measure, report, understand greenhouse gas emissions
Challenges for Information Access in Multi-Disciplinary Product Design and En...Dirk Ahlers
In any larger engineering setting, there is a huge number of documents that engineers and others need to use and be aware of in their daily work. To improve the handling of this amount of documents, we propose to view it under the angle of a new domain for professional search, thus incorporating search engine knowledge into the process. We examine the use of Information Retrieval (IR), Recommender Systems (RecSys), and Knowledge Management (KM) methods in the engineering domain of Knowledge-based Engineering (KBE). The KBE goal is to capture and reuse knowledge in product and process engineering with a systematic method. Based on previous work in professional search and enterprise search, we explore a combination of methods and aim to identify key issues in their application to KBE. We list detected challenges, discuss information needs and search tasks, then focus on issues to solve for a successful integration of the IR and KBE domain and give a system overview of our approach to build a search and recommendation tool to improve the daily information- seeking workflow of engineers in knowledge-intense disciplines. Our work contributes to bridging the gap between Information Retrieval and engineering support systems.

Granularity as a Qualitative Concept for Geographic Information Retrieval (GIR)Dirk Ahlers
This document discusses a new 3D model of the city of Trondheim, Norway that was created to make urban planning and navigation easier. The 3D model includes detailed geographic information down to the 1 meter level, showing individual buildings, streets, and other infrastructure. It covers the entire municipality at different levels of granularity from 1 meter to 100km, integrating data that was previously dispersed across different agencies and datasets.
Visualizing a City Within a City — Mapping Mobility Within a University CampusDirk Ahlers
Urban mobility analysis usually examines large cities or even regions. We take another angle and examine a university campus as a city within a city to focus on small-scale and hyperlocal characteristics. The campus mobility data exhibits a high spatial and temporal granu- larity that we use to drive analyses and visualizations towards the aim of campus analytics. We describe the abstraction approaches and visualiza- tions used towards the development of our tool and share initial results of campus analytics.

NTNU Climate-KIC Lessons: Learnings from project development with Climate-KICDirk Ahlers
Dr. Dirk Ahlers presented his experiences with projects developed through Climate-KIC, the European Institute of Innovation and Technology's climate innovation arm. He discussed two projects he led - Carbon Track and Trace (CTT), an IoT emission sensor network, and its follow-up CTT2.0. He highlighted benefits like the interesting European network, focus on climate impact and innovation, and opportunities for applied research. However, he also noted caveats like complex structures, changing reporting requirements, and limited feedback on proposals. He recommended understanding the EU landscape, starting with smaller projects, carefully checking finances, and validating ideas with Climate-KIC.

This document discusses growing and replicating Positive Energy District (PED) sites in urban environments. It outlines several PED pilot projects across European cities and proposes strategies for scaling PEDs within and across cities. These include starting from local renewable energy generation hubs, growing existing PEDs, and establishing new PEDs. Annual energy balances and sharing surpluses with neighboring areas are key to allowing PEDs to "carry" less efficient zones. The document also advocates activating cities' innovation potential through urban living labs and knowledge sharing between projects to facilitate PED replication.

Surveying GeoNames Gazetteer Data for the Nordic CountriesDirk Ahlers
This paper takes a look at freely available gazetteer data for the Nordic countries. We examine locations in this region to understand their characteristics and the quality of the available data. Several indicators are developed and discussed to estimate the expected data quality. The distribution and coverage of the data is mapped and the accuracy and quality indicators are visualized. The used method focuses on populated places as locations of interest but can be extended to arbitrary types of locations. The results give insights into the distribution of issues based on multiple indicators and give an estimate of per-country data quality.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
