This paper presents an application of the Kalman filter in signal processing in instrumentation systems when the conditions of the environment generate a large amount of interference for the acquisition of signals from measurement systems. The unwanted in... see more

For all onboard systems applications, it is important to have very low-loss characteristics and low power consumption coupled with size reduction. The controls and instrumentation in defence and aerospace continually calls for newer technologies and devel... see more

The technological developments in microelectromechanical systems (MEMS) have resulted in conceptualisation of a next generation observation system called global environmental MEMS sensors (GEMS). GEMS consists of a large number of airborne probes that wil... see more

Aim: To evaluate the foraminal transportation during foraminal enlargement after manual instrumentation with stainless steel files, preparation with the Mtwo system and Reciproc R25 file. Methods: Thirty roots were selected, divided in three groups and pr... see more

Objectives: During root canal preparation, apical extrusion of debris can cause inflammation, flare-ups, and delayed healing. Therefore, instrumentation techniques that cause the least extrusion of debris are desirable. This study aimed to compare apical ... see more

Objective: This study aimed to analyze the influence of the instrumentation technique (hand or rotary), and apical enlargement on calcium hydroxide (CH) fillings in curved canals. Materials and method: One hundred and ten simulated root canals were divide... see more

The acquisition of tools and instruments to quantify the magnitude of climatic phenomena such as rainfall, temperature and seismic activity are necessary for the proper development of studies and extrapolation of data to analyze, identify and mitigate any... see more

Remote Access Laboratories are being used around the globe to enable engineering students to practice practical skills and enhance their knowledge through hands-on experimentation. These facilities also increase access by allowing users to undertake exper... see more

To enable clients to view real-time video of the involved instruments during a remote experiment, two real-time video streaming systems are devised. One is for the remote experiments which instruments locate in one geographic spot and the other is for tho... see more
