This paper investigates the semantic search performance of search engines. Initially, three keyword-based search engines (Google, Yahoo and Msn) and a semantic search engine (Hakia) were selected. Then, ten queries, from various topics, and four phrases, having different syntax but similar meanings, were determined. After each query was run on each search engine; and each phrase containing a query...
This paper deals with cooperative path and cooperative perception of Unmanned Aerial Vehicles (UAVs) in dynamic environment. Differential geometry techniques based on Pythagorean Hodographs (PH) are adapted to plan cooperatively path of UAVs in order to avoid obstacles. These obstacles are proposed in this paper to be both static and moving obstacles. In case of moving obstacles, we propose to develop...
In this paper we propose a new artificial neural network model for TCP congestion control based on four parameters 1 loss event rate (p) 2. Round trip time (RTT) 3 retransmission time out (RTO) 4 numbers of packets acknowledged by an arriving ACK (b).we believe that with inclusion of b proposed neural network model will more accurately estimate TCP throughput. In new concept of ACK compression in...
