BonnTour: benchmarks & solutions for vehicle routing with time-dependent travel times
No full textThis repository contains the new vehicle routing benchmark instances that we created as part of our work on vehicle routing with time-dependent travel times.
To create this benchmark set, we used map data copyrighted by OpenStreetMap contributors and available from https://www.openstreetmap.org under the Open Database License (ODbL) v1.0, and speed data retrieved from Uber Movement, (c) 2022 Uber Technologies, Inc., https://movement.uber.com, under a Creative Commons Attribution Non-Commercial license.

Chromatic Numbers from Exact Decision Diagrams in Exact Arithmetic
No full textThis dataset contains source code and consoles for computing chromatic numbers
with exact decision diagrams, solving integer programs with exact arithmetic.
The chromatic number of the DIMACS instance r1000.1c could be determined
for the first time.
There are 3 files:
- ddruns_main.zip contains scripts to reproduce the results
- ddruns.tar contains the consoles and SCIP-exact certificates from our exeriments

Number of Land Cover Changes in Kenya between 2001 and 2011
No full textMODIS provides the Land Cover Type Product MCD12Q1 (Friedl et al., 2002) with 500m grid resolution which represents the same pixel size also used for the MODIS NDVI time-series analysis. Annually data provision and a matching pixel size with the MODIS NDVI data used earlier in this study were key elements for choosing this dataset. The Map shows the number of LULC changes as calculated based on the methods described in chapter II.3.3. Stable areas – where land cover changes are zero – can be identified in southern Kenya, Kajiado County in particular, but also in western Kenya north of Lake Victoria, around Lake Turkana, and in the northeastern part of Kenya bordering Ethiopia. Around 33.16% of the total land area experience zero changes from 2001-2011 while 16.11% changed once and 22.92% show two changes. Three (13.98%), four (9.53%) and five (3.42%) changes can still be observed in Map III.11 while areas experiencing more than five changes are occurring in less than 1% of the total land area.
The different classes show the number of land cover changes within the observation period.
Quality/Lineage: Data was reclassified and analysed in R. Extraction of each land cover change per year and analysis of how many changes occurred in the observation period. Visualization was done in ArcGIS.
Purpose: Number of Land Cover Changes in Kenya between 2001 and 201
An Unsupervised Baseline For Dialogue Breakdown Detection Using Ouf-of-distribution Detection
No full textFor the last several decades, a focus of artificial intelligence work has been computer-based systems for interacting with humans. Such a system must ensure smooth communication to provide thoughtful answers by interacting with the system. A major critical issue is they can create an unwanted statement that results in a breakdown of dialogue, which degrades the overall interaction quality. Thus, it is incredibly beneficial to employ a system to detect whether a breakdown hampers the conversation flow. In this work, we propose an unsupervised dialogue breakdown detection technique that can be trained using only dialogue data and no other supervision. Our experiments show that using out-of-distribution detection methods can perform on par with competing supervised methods that use labeled English data. On the DBDC4 benchmark, it is the only unsupervised approach to our knowledge
Resolving Insolvency, Ranking of Economy, 2017
No full textEconomies are ranked on their ease of doing business, from 1–186. A high ease of doing business ranking means the regulatory environment is more conducive to the starting and operation of a local firm. The rankings are determined by sorting the aggregate distance to frontier scores on 10 topics, each consisting of several indicators, giving equal weight to each topic. The rankings for all economies are benchmarked to June 2017.
Quality/Lineage: The data is downloaded from the above link http://www.doingbusiness.org/rankings and manipulated only table format keeping the value same for all the countries as the requirement of the Strive database. The map is created based on the values of the country using rworldmap package in R
Environmental Democracy Index (Rank) 2014
No full textEnvironmental Democracy Index (EDI) consists of 75 legal indicators developed under 23 of the UNEP Bali Guidelines that are concerned with the development and implementation of legislation. In addition to the legal indicators, EDI includes 24 supplemental indicators that assess whether there is evidence that environmental democracy is being implemented in practice. The EDI legal indicators assess laws, constitutions, regulations and other legally binding, enforceable rules at the national level.

Decoding Fairness in the Value Chain of the Tagbanua Wild Honey Community Forestry Enterprise. Poster on Tropentag 2016
No full textOne of the traditional livelihood practices of indigenous Tagbanuas in Palawan, Philippines is wild honey gathering from the giant honey bee. In order to analyse the linkages of the social and ecological systems involved in this indigenous practice, we conducted spatial, quantitative, and qualitative analysis on field data gathered through GPS mapping, community surveys, focus group discussions, and key informant interviews. We found that only 24% of the 251 local community members surveyed could correctly identify the giant honey bee. Inferential statistics showed that a lower level of education and higher household vegetation contribute to correct identification of the giant honey bee. Spatial analysis revealed that mean NDVI of sampled nesting tree areas has dropped from 0.61 in the year 1988 to 0.41 in 2015. This reduction on vegetation cover may contribute to reduced bee-human interactions and may also be an indication that commercialising non-timber forest products is not fulfiling its objective of development alongside conservation. Indigenous wild honey hunting and gathering as an ICDP shows the complexity of the social-ecological system of forest communities. It also shows the difficulty of getting a win-win situation out of simultaneous pursuit of forest conservation and rural development. Knowledge shifts can, indeed, occur from the interaction of ecological and social factors and we see that if resource management interventions do not employ a systems approach, it can overlook important feedback. NGO interventions should not only facilitate the learning of visible resource managers like wild honey hunters but of the community as a whole.
