Search for information about monuments, business establishments and façades is a recurring task for travelers and citizens of large cities. However, even when the person is in front of the place of interest, the language and the inaccuracy of the GPS receivers integrated in mobile phones may make it difficult the precise identification of the site. We present a tool that is capable to identify ...

Many studies have supported the enemies hypothesis, which suggests that natural enemies are more efficient at controlling arthropod pests in polyculture than in monoculture agro-ecosystems. However, we do not yet have evidence as to whether this hypothesis holds true in peach orchards over several geographic locations. In the two different geographic areas in eastern China (Xinchang a town in t...

NameSet is a system that translates a set of geographic coordinates into a textual name based on the geographic regions where the coordinates occur. One possible application of NameSet is to concisely present the geographical scope of a set of geo-referenced observations to a human user. Another application is to generate text to depict a set of coordinates that appear on a web site – text that...

The diversity of Trichoderma spp. was investigated in alkaline soils of pistachio orchards at different geographic areas in Kerman province, Iran. A total of 161 Trichoderma isolates were obtained and identified at the species level by their morphological characters and sequence analysis of their internal transcribed spacer (ITS) and tef1-α genomic regions. Totally, five species of Trichoderma ...

We introduce and evaluate a very simple landmark-based network partition technique called Hierarchical Bipartition Routing (HBR) to support greedy routing with delivery guarantee in wireless ad hoc sensor networks. The main assets of HBR are: 1) packet delivery guarantee, 2) unique virtual addressing, 3) no packet overhead in typical cases, 4) small routing tables, 5) no physical geographic coo...

Most documents can be said to be related to some form of geographic context and, recently, geographic information retrieval has captured the attention of researchers from fields related to text mining and data retrieval, envisioning the support for tasks such as map-based document indexing, retrieval and visualization. In this paper, I empirically evaluate automated techniques, based on a hiera...

Seismic data is difficult to analyze and classical mathematical tools reveal strong limitations in exposing hidden relationships between earthquakes. In this paper, we study earthquake phenomena in the perspective of complex systems. Global seismic data, covering the period from 1962 up to 2011 is analyzed. The events, characterized by their magnitude, geographic location and time of occurrence...

Crop yield estimation is an essential element in apple orchard management. Apple growers currently predict yield based on historical records and manual counting. These methods require extensive experience on the part of farm managers to take into account variations in weather, soil conditions, pests, etc., and are generally labor-intensive and inaccurate. In this work, we propose an automatic c...
