The present paper proposes a just-in-time (JIT) control method for a free-joint manipulator moving in a horizontal plane. The manipulator consists of two links, where only the first link at the base is driven and the second link has a passive joint. Although it is difficult to control the manipulator by conventional methods, a human can operate the manipulator at a certain level. The input of a human operator is observed and is regarded as a rectangular signal. The control input is then represented in terms of the parameters of the rectangular signal. The database for the proposed JIT control system is constructed using these input parameters. Experimental and simulation results reveal that, by using the proposed control method, both of these links successfully reach the target angles. However, the control method is only useful when the target angle for the free link is relatively small. The simulation results reveal that the performance of the control method depends on the target angle and on the parameters of the manipulator. The reason for this dependency is discussed based on the distribution of the database. The discussion suggests that the performance may be improved by modifying the database such that data will be distributed throughout the range of the target position.

Sensor faults affect the system's performance in the closed loop when the faulty sensor readings are used in a feedback control system. This paper presents an observer based sensor fault tolerant control system for practical implementation on modified feedback configuration for close loop control systems. The purpose of this system is to maintain the safety of the system and reliability of the process even in presence of sensor fault by adjusting or modifying the control laws based on a comparison with the state observer. The observer based sensor fault compensating element that is physically connected in parallel with the nominal closed loop system does not interfere with nominal operations i.e. when sensors are not faulty, but will implicitly provide sensor fault compensation signals when sensor fault occurs. An augmentation of an observer based element is required to generate sensor fault compensating signals to a typical feedback control system when sensor fault occurs. In effect, sensor fault tolerance is introduced thus improving control system reliability. A temperature control system is used as a case study. Results of simulation and real time implementation for temperature control system concur and demonstrate the applicability and the obvious improvement of typical closed loop control system reliability via the proposed scheme.

Hybrid systems are systems in which the discrete dynamics and the continuous dynamics not only coexist but also interact with each other. The modeling of such hybrid systems is different from the convention modeling techniques followed for purely discrete or purely continuous systems. Development of techniques for Modeling, system identification and controller synthesis of hybrid systems is an upcoming research area. In this paper a three tank benchmark system is modeled using hybrid modeling technique and the modeled system is simulated using SIMULINK and a controller is designed for the hybrid system using STATEFLOW in MATLAB.

This study presents the design and validation of imaging tools to access and analyses the development of microvessel and angiogenesis inside a tridimensional (3D) cell culture system. Angiogenesis is a key mechanism during normal development as well as in cancer cell growth. Phase contrast, fluorescence, and confocal microscopy were used to determine the cell attachment, tube-like structure formation and other cellular events inside our 3D system.

Dynamic path planning is one of the challenging research problems which is needed to guide UAV (Unmanned Aerial Vehicle) for moving target intercept. This research is to develop an algorithm for moving target intercept with obstacle avoidance in 3D. The algorithm which is called L+Dumo Algorithm integrate a modified Dubins Algorithm and Linear Algorithm. The simulation is conducted using one UAV and one moving target with an obstacle of cylindrical shape in between both objects. The result shows that the algorithm can guide UAV to approach the moving target with the accuracy of 67.417% L+Dumo algorithm will solve dynamic path planning problem for moving target intercept in 3D with minimum complexity of computation.

Acoustical comfort in a hospital is required for recovering process, improving quality of sleep, improving patient's comfort factor, and also to enhance medical staff's working quality. A research related to acoustical comfort was conducted at the Intensive Care Unit (ICU) Hospital in Bandung, Indonesia. Acoustic parameters that are discussed in this paper are definition-50 (D-50), sound pressure level (SPL), and reverberation time (T-30). These parameters are measured and modified by simulation, actual measurement, subjective observation, and passive acoustic recommendation. Data from simulation shows that both T-30 and D-50 values (especially in speech frequency) are just slightly around the standard value, while simulation and actual measurement show that SPL value is above the standard of 35 dBA. On the other hand, subjective observation shows that noise sources are dominated by speech (250Hz–1,000Hz) and intermittent noise from alarm (1,000Hz–2,000Hz). Recommendation was determined through simulation by changing/coating concrete wall with fiberglass board. After recommendation, the values for D-50 and T-30 are 17.6%–88.7% and 0.3s–1.0s, respectively. For SPL (and Leq) parameter, there is a decrease of 7.7dBA (in patient's area) and 2.5dBA (in nurse's area). Overall, D-50 parameter is increased while both T-30 and SPL parameters are decreased, which considered better for acoustic environment in a hospital.

Pelvic tilt posture is the key to ideal standing posture, yet no accurate quantitative measurements with standardized protocols have been implemented. The aim of the current study was to assess the calibration of a newly developed pelvic tilt sensor and to compare the repeatability using 2 protocols. Pelvic tilt was measured in a healthy woman with two different protocols and two repeated test were carried out for each protocol by a single tester. Repeatability testing for sagittal pelvic tilt was measured during neutral standing (NP), maximal anterior pelvic tilt (APT), and maximal posterior pelvic tilt (PPT). The newly developed pelvic tilt sensor was calibrated manually with a goniometer and indicated excellent correlation (r=0.99). NP, APT, and PPT in protocol 1 showed poor intra-class correlation (ICCs) compared to protocol 2 which showed high ICCs (r≥0.90) and low standard error of measurement (SEM). The excellent results obtained using the newly developed pelvic sensor in protocol 2 shows that it can be potentially used in clinical practice.

A robotic sensor network is advantageous in performing a coverage task compared to the static sensor network due to its ability to self-deploy and self-reconfigure. However, due to the limited sensing range, when mobile sensors are initially deployed, sensors located far away from the area of interest may not be able to participate in the coverage task. Furthermore, since in reality the mobile sensors have only a limited energy storage, the movement of the sensors have to be as efficient as possible. In this paper, we consider a robotic sensor network with a limited anisotropic sensing range and energy storage. The sensing performance is assumed to be dependent on both the position and orientation of the target to the sensor and its range is reduced along with the movement of the mobile sensor. This paper proposes a new algorithm that guarantees the participation of all sensors in the network while at the same time maintains the energy utilization as optimum as possible. We combine the standard coverage algorithm with the leader-following algorithm where the standard coverage algorithm is further modified in order to take into account the energy consumption of the sensors. Simulations show the effectiveness of the proposed algorithm.
