Realistic Lighting for Interactive Applications Using Semi-Dynamic Light Maps
Öztürk, Bekir; Akyüz, Ahmet Oğuz (2020-12-01)
Light mapping is a technique that works by precomputing the lighting of a scene to speed up expensive lighting calculations at run-time. It is a commonly employed technique for computer games, in particular mobile games, d...
Supervised approaches for explicit search result diversification
Yigit-Sert, Sevgi; Altıngövde, İsmail Sengör; Macdonald, Craig; Ounis, Iadh; Ulusoy, Özgür (Elsevier BV, 2020-11-01)
Diversification of web search results aims to promote documents with diverse content (i.e., covering different aspects of a query) to the top-ranked positions, to satisfy more users, enhance fairness and reduce bias. In th...
Energy-efficient and fault-tolerant drone-BS placement in heterogeneous wireless sensor networks
Deniz, Fatih; Bagci, Hakki; KÖRPEOĞLU, İBRAHİM; Yazıcı, Adnan (2020-11-01)
This paper introduces a distributed and energy-aware algorithm, called Minimum Drone Placement (MDP) algorithm, to determine the minimum number of base stations mounted on resource-rich Unmanned Aerial Vehicles (UAV-BS), c...
