This paper deals with the development of a fault-free model of the pneumatic subsystem of an air brake system that is used in commercial vehicles. Our objective is to use this model in brake control and diagnostic applications. The development of a diagnostic system would be useful in automating enforcement inspections and also in monitoring the condition of the brake system in real-time. This paper presents a detailed description of the development of this model and of the experimental setup used to corroborate this model for various realistic test runs.

Investigation of the effect of pulsed electric field on eukaryotic cells has been of interestto biomedical scientists and researchers since a few decades. Reversible electroporation (EP) is used for uptake of chemicals, drugs, DNA into the eukaryotic cells under low electric field (100’s V/cm) of millisecond duration to few hundreds of microsecond duration. An electric field of nanosecond duration and a very high electric field (50’s kV/cm) can stress to intracellular organelles of eukaryotic cells and that can trigger apoptotic pathways. In this article experimental setup has been prepared for real-time investigation of the effect of nanosecond electric field on eukaryotic cells. Pulsar producing ~1.5kV, 20ns FWHM, single shot as well as ~10Hz rep-rate with rise-time as fast as ~10ns, has been prepared using blumlein pulse forming line and avalanche transistor switches. A 300µm gap microplate chamber has been prepared to expose the electric fieldtoeukaryotic cells.

Real-time human intent recognition is important for controlling low-limb wearable robots. In this paper, to achieve continuous and precise recognition results on different terrains, we propose a real-time training and recognition method for six locomotion modes including standing, level ground walking, ramp ascending, ramp descending, stair ascending and stair descending. A locomotion recognition system is designed for the real-time recognition purpose with an embedded BPNN-based algorithm. A wearable powered orthosis integrated with this system and two inertial measurement units is used as the experimental setup to evaluate the performance of the designed method while providing hip assistance. Experiments including on-board training and real-time recognition parts are carried out on three able-bodied subjects. The overall recognition accuracies of six locomotion modes based on subject-dependent models are 98.43% and 98.03% respectively, with the wearable orthosis in two different assistance strategies. The cost time of recognition decision delivered to the orthosis is about 0.9[Formula: see text]ms. Experimental results show an effective and promising performance of the proposed method to realize real-time training and recognition for future control of low-limb wearable robots assisting users on different terrains.

Laboratory experiments are an important and integral part of the learning experience for undergraduate engineering students. They help the students in getting hands-on experience and in better understanding theoretical concepts. In recent years, a significant number of remotely accessible experiments have been developed and integrated into engineering laboratory courses at many educational institutions worldwide. There exist several approaches and technologies for making experimental hardware accessible via the Internet. This paper will discuss some of the available technologies and a specific method for acquiring data from experimental setups via LabVIEW Virtual Instruments over a network. As an example, a remote experimental apparatus that was developed by upgrading a commercially available air flow rig with remote control and monitoring capabilities is presented. This system is used in a junior-level mechanical engineering course on fluid mechanics. It enables the students to access the experimental setup via the Internet either in real-time or batch mode. For real-time use of the experimental setup, remote panels are used. These remote panels are exactly the same as those that would be used on a local on-site server. They can be run under LabVIEW’s Web server to be observed and controlled by the client via any Internet browser. For the batch-mode use of the experimental setup, on the other hand, simple HTML pages in conjunction with forms are used to generate experimental requests that are sent to the LabVIEW server. This server then places these experimental requests in a queue and executes the appropriate LabVIEW scripts on a first-come first-served basis. This paper will discuss and compare both methods for performing remote laboratory experiments.

One of the challenges in teaching applied control theory is to provide students with easy to understand experimental setups, which show complex but comprehensible dynamical behavior. We propose a flying-ball-in-tube experiment with stable, critically stable and unstable behavior. The benefit of the flying-ball-in-tube experiment are its in respect to time scale observable dynamics as well as the simplicity of the setup. A model of the flying-ball-in-tube experiment is derived and analyzed with respect to its stability properties. The derived model is identified and the predicted behavior is validated. In addition, the use of the experimental setup within a one week undergraduate practical is described. Within the course the students program the control environment on a micro controller within the FreeRTOS real time environment and design their own control structure.

This paper analyzes the signals captured during the movement of a mechanical manipulator carrying a liquid container. In order to study the signals an experimental setup is implemented. The system acquires data from the sensors, in real time, and, in a second phase, processes them through an analysis package. The analysis package runs off-line and handles the recorded data. The results show that the Fourier spectrum of several signals presents a fractional behavior. The experimental study provides useful information that can assist in the design of a control system to be used in reducing or eliminating the effect of vibrations.

In this work, vibration characteristic diagnosis of misalignment rotor in loosely fitted bearing is investigated using dimensional analysis (DA) approach. A comprehensive empirical model (EM) using nondimensional parameters is developed to diagnose the rotor-bearing system, and EM model has been validated through an experimental setup developed in-house. Experiments are performed for various defects such as misalignment and bearing looseness. The EM results can be used to monitor the real-time conditions of the rotor-bearing system. This work also presents the effect of misalignment and bearing looseness under various load and speed conditions. Further, work has been extended to predict the combined effect of bearing looseness and misalignment. It has been found that EM model predictions of the vibration amplitude are better when compared to experimental results.

This paper present the performance of Fuzzy logic controller in maintain level of water in water tank system. The mathematical modelling was developed to get the initial idea of the system performance. Later, the prototype of water tank system were constructed and tested to get the real time results. The Takagi-Sugeno “on” and “off” interference technique method was implemented due to the control limitation of the pump motor that being used in the experimental setup. The fuzzy logic controller was realized by embedded the algorithm in microcontroller of the water tank system. The experimental results show acceptable level of water within the range of 18cm to 20.5cm and settling time 59 seconds with 20 cm set point.
