1. 6. A comparison of remote sensed semi-arid grassland vegetation anomalies detected using MODIS and Sentinel-3, with anomalies in ground-based eddy covariance flux measurements.

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Jason Craig Joubert; [2023]
   Nyckelord :Geography; GIS; Anomaly Detection; Remote Sensing; fAPAR; GDMP; GPP; MODIS; Sentinel-3; Earth and Environmental Sciences;

   Sammanfattning : Remote sensed vegetation biophysical indicators are derived from various sensors and methods and contribute to the quantification of vegetation growth. They are used as inputs to early warning systems for crop yield estimation, thus improving crop management and food security. LÄS MER

3. 7. AXI-PACK : Near-memory Bus Packing for Bandwidth-Efficient Irregular Workloads

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Chi Zhang; [2022]
   Nyckelord :General propose processor; on-chip bus protocol; irregular memory access; ASIC digital circuit design.; Generellt förslag på processor; on-chip-bussprotokoll; oregelbunden minnesåtkomst; digital ASIC-kretsdesign.;

   Sammanfattning : General propose processor (GPP) are demanded high performance in dataintensive applications, such as deep learning, high performance computation (HPC), where algorithm kernels like GEMM (general matrix-matrix multiply) and SPMV (sparse matrix-vector multiply) kernels are intensively used. The performance of these data-intensive applications are bounded with memory bandwidth, which is limited by computing & memory access coupling and memory wall effect. LÄS MER

4. 8. Evaluation of the LPJ-GUESS crop model under ambient and elevated CO2 concentrations.

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Annika Nitschke; [2022]
   Nyckelord :LPJ-GUESS; free-air carbon dioxide enrichment experiments; elevated CO2; climate change; wheat yield; Earth and Environmental Sciences;

   Sammanfattning : In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. LÄS MER

5. 9. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Juliane Glinski; [2022]
   Nyckelord :sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

   Sammanfattning : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. LÄS MER

7. 10. How to combat the climate change with EU Public Procurement law - Mandatory obligations or award criteria?

   Magister-uppsats, Lunds universitet/Institutionen för handelsrätt

   Författare :Xue Ouyang; [2021]
   Nyckelord :EU Public Procurement Law; Climate Change; Law and Political Science;

   Sammanfattning : There are great challenges we have to face in the environmental and climate field, especially when greenhouse gas emissions are changing the conditions for human life and impacting biodiversity. The main reason resulting in climate change is greenhouse gas emissions during production and consumption of goods and services. LÄS MER
