In conservation agriculture, the no-tillage cultivation system and retention of permanent vegetal cover are crucial to control soil erosion by water. This paper analyses maize under no-tillage, with particular reference effect produced on when weed is performed a hand tool (machete), which disturbs surface soil, behavior in these circumstances. The study area located humid tropical mountains no...

Speech recognition is one of our most effective communication tools when it comes to a hands-free (human-machine) interface. Most current speech recognition systems are capable of achieving good performance in clean acoustic environments. However, these systems require the user to turn the microphone on/off to capture voices only. Also, in hands-free environments, degradation in speech recognit...

Formal specification and verification of software have made small but continuous advances throughout its long history, and have reached a point where commercial tools became available for verifying programs semi-automatically or automatically. The aim of the master thesis is to evaluate commercial and academic verification tools with respect to their usability in developing software and in teac...

Hand-held power tools used for fastening operations exert high dynamic forces on the operator's hand-arm, potentially causing injuries to the operator in the long run. This paper presents a study that analyzed the vibrations exerted by two hand-held power tools used for fastening operations with the operating exhibiting different postures. The two pneumatic tools, a right-angled nut-runner and ...
