(Received 00 Month 200x; In final form 00 Month 200x) We describe the design, implementation, and evaluation of Molé, a mobile organic localisation engine. Unlike previous work on crowd-sourced WiFi positioning, Molé uses a hierarchical name space. By not relying on a map and by being more strict than uninterpreted names for places, Molé aims for a more(More)
OBJECTIVE To study the incidence of testicular and epididymal appendages in patients with cryptorchidism. MATERIALS AND METHODS We studied 65 patients with cryptorchidism, totalizing 83 testes and 40 patients who had prostate adenocarcinoma and hydrocele (control group), totalizing 55 testes.

—Current mobile devices continuously estimate their locations, allowing users to " check in " , find nearby friends and interests, and determine routes to their destinations. While underlying satellite, cell, and WiFi-based positioning systems can return an accurate and meaningful position in many cases, extending them to work energy-efficiently,(More)
In this paper an analysis of a distributed control system based on Java is presented. A classical PID controlled system is implemented simulating each part of a real control system running in different computers connected to a local area network. The communication message time periods and their jitter are measured running the system in different computer(More)
