    This paper describes a method that allows accuracy and bandwidth enhancements in 3D sound intensity measurements. Commercial 3D probes are usually set up with three mutually perpendicular 1D p-p probes and, thus, arranged with six microphones; although sound intensity can be calculated with 15 independent pairs of transducers, only the three "primary" pairs that are aligned with the coordinate system axes. The other 12 "secondary" pairs consist of mutually perpendicular microphones, which are placed at a distance that is radic2 times shorter than the primary one. The main idea of the proposed method is to average the intensity that is measured on primary and secondary pairs. This leads to a larger bandwidth, thanks to the shorter separating distance between secondary pairs. The intrinsic p-p method high- frequency sensitivity loss is partially recovered, starting from the theoretical plane wave expression. Measurements of different axes are weighted with coefficients that are computed by optimizing the measurement uncertainty. Errors that are due to the metrological characteristics of the transducers and the effects of environmental conditions are compensated. Experimental results showed that a p-p probe arranged with half-inch microphones that are placed at a distance of 50 mm allows reliable measurements up to 2.5 kHz, whereas a commercial probe bandwidth with the same configuration is usually 1250 Hz.

    Search engines usually publish search results on web pages that are filled with a certain number of matched records that can be further navigated through successive back and forth operations. While this approach proves to be useful, it fails to show the context and relationship among displayed results. We argue that new and intuitive user interfaces, such as 3D virtual environment interfaces, may provide an alternative to the traditional presentation techniques, particularly in a learning environment where learners are looking for multimedia learning resources that match their interests. We propose a 3D car gaming environment such as a search metaphor and analyze the suitability of such an approach in terms of user perception, interaction, visual quality, graphics-rendering performance, and other parameters. Our experiment suggests that the proposed approach not only shows an intuitive way of information visualization but also integrates education and entertainment to serve the vision of Edutainment.

    Research performed in the area of haptics has produced some remarkable results with a variety of haptic devices. However, haptic-based applications are designed to consider only a particular haptic device. Therefore, the functionality of a haptic-based system is limited by the chosen device's features, such as workspace, device's inertia, friction, number of points of interaction, number of degrees of freedom, and maximum force that can be exerted. In short, these haptic-based systems are limited for use with a certain haptic device. Without a doubt, the need for a software tool to adapt existing haptic-based systems to the capabilities of another haptic device is evident. On the other hand, one of the main advantages of using haptic devices is the possibility of saving data during the haptic interaction. Our proposed framework, which is called Adaptive Haptic Application (AdHapticA), deals with both issues: It automatically adapts a haptic-based system to be used with another haptic device and saves the corresponding haptic data for quantitative evaluation. The AdHapticA framework can be used to study the feasibility of certain haptic devices to meet the requirements of an application. A case study is presented to evaluate single-point interaction and hand exoskeleton haptic devices for authentication purposes by using the same virtual scenario. The applicability of the proposed framework is shown, and the results obtained from the haptic data are captured when a particular application is performed with either single-point (desktop device) or multipoint interaction devices (hand exoskeleton). Therefore, the results have shown that current hand exoskeleton devices are less suitable for tasks that require a certain level of precision, like haptic-biometric-based tasks. View full abstract»

    The problem of stable force-reflecting teleoperation is addressed, where the communication between the master and the slave is subject to multiple time-varying, discontinuous, and possibly unbounded communication delays. A new force reflection (FR) algorithm is proposed, which improves the stability of the system without decreasing its transparency. Based on the estimate of human forces provided by the high-gain input observer, the proposed algorithm restricts the reflected force in such a way that it eliminates the motion of the master induced by the FR signal without changing the human perception of the environmental force. It is shown that the proposed FR algorithm allows us to achieve stability of the system for an arbitrarily high FR gain and arbitrarily low damping and stiffness of the master manipulator. The stability analysis is based on the input-to-output stability small-gain theorem for systems with multiple time-varying communication delays. View full abstract»

    Six-degree-of-freedom (6-DoF) haptic rendering of the telerobotic operation method using virtual joint coupling (VJC) is proposed. This algorithm couples six joints of a virtual robot with those of a 6-DoF haptic device based on a spring-damper model to render force and torque feedback to a user and drive the virtual robot in the teleoperation simulation. Our rigid body dynamics is decoupled from the haptic rendering loop with an open dynamic simulation library Open Dynamics Engine, which runs at a lower update rate, thereby alleviating computation demand and improving the stability of the system. To illustrate the role of haptics and physically based simulation in teleoperation, a path-following experiment with virtual constraints is carried out. An experiment of virtual assembly, in which a user performs assembly tasks by means of manipulation of a gripper mounted at the end of a virtual robot, is also implemented to verify the VJC algorithm.

    Nowadays, stroke is one of the most frequent causes of severe adult disability in the world. Virtual reality and haptic technologies have emerged as promising assistive tools for effective diagnosis and rehabilitation intervention. The objective of this paper is to develop and test a set of five virtual exercises on top of a framework, which is designed for the diagnosis and rehabilitation of patients with hand impairments. We have implemented task-oriented exercises based on well-established and common exercises, namely the Jebsen Test of Hand Function and the Box and Block Test. These include moving a cup, arranging blocks, navigating a maze, training with a dumbbell, and grasping a rubber ball. Furthermore, key performance measures (metrics) are proposed for each exercise to quantitatively evaluate and judge the performance of stroke patients. Our evaluation of these exercises shows promising potential to define ldquogoldenrdquo reference metrics for healthy subjects, against which the performance of a patient is compared. This will facilitate the ability of occupational therapists to assess the patient's progress. View full abstract»

    An agent-based profiling approach is presented in this paper in the form of a virtual interface that models user behavior and satisfaction with the objective of improving the performance of high-performance computing (HPC) centers. The interface's function is to translate user requests and satisfaction criteria into what is really necessary, thus permitting the optimization of the HPC center's scheduling, taking into account the predicted user satisfaction together with the objectives of the management of the center in terms of resource usage and cost. The system is built using an evolutionary agent-based profiling architecture where agents are evolved in real time to adapt to the different users. These agents cooperate with the scheduling mechanism, providing resource usage estimations for the different tasks, as well as predicting the effect of possible strategies on user satisfaction. This paper focuses on the user behavior modeling component, although the global architecture is also presented. Some experiments are carried out where the proposed architecture interacts with a real job-management system (JMS) (sun grid engine). They clearly show that modeling the user and taking user satisfaction into account helps to improve system performance. View full abstract»

    Remote exploration of detailed virtual environments (VEs) on mobile devices with acceptable frame rates has become a challenging and interesting research topic. With recent advances in mobile computing devices with communication and multimedia capabilities, remote VE walk-through and real-time streaming for mobile devices have opened a new class of 3-D VE exploration-based applications such as virtual guides and malls, online gaming, training, and monitoring, just to name a few. Furthermore, emergency preparedness types of applications can benefit from mobile 3-D visualization systems to support emergency responders with critical information about the disaster area. The combination of sensor networks with VEs can provide a physical environment monitoring and measurement system with live information about the target environment that can be visualized in real time. The challenge lies in how to provide a rich and detailed 3-D VE on thin mobile devices that are known for their lack of proper resources to process large-scale 3-D geometric data. Our approach consists of moving the demanding geometry-rendering task to a dedicated remote rendering server that streams the rendering output to a client, leaving only the displaying and certain minor image-based rendering tasks to the local, less-powerful mobile hardware. In addition, wireless networks pose significant challenges to multimedia streaming due, for the most part, to the mobility-induced changes in bandwidth and errors in the wireless channel. In this paper, we focus on the implementation, measurement, and analysis of an image-based VE streaming strategy. We define a new approach to remote rendering and interactive visualization of 3-D VEs on thin mobile devices. To this end, we propose end-to-end streaming and rate control protocols, as well as buffering and scheduling mechanisms to support the requirements of bandwidth-demanding multimedia systems. The main purpose of our proposed rate control scheme is to achieve- - both high end-to-end throughput and low frame-rate fluctuation to adapt data traffic to the frequent changes of the bandwidth and error rate present in wireless networks. We discuss the design of our proposed solutions and report on their performance evaluation through an extensive set of simulation experiments. View full abstract»

    This paper presents an innovative mobile robot navigation technique using radio frequency identification (RFID) technology. Navigation based on processing some analog features of an RFID signal is a promising alternative to different types of navigation methods in the state of the art. The main idea is to exploit the ability of a mobile robot to navigate a priori unknown environments without a vision system and without building an approximate map of the robot workspace, as is the case in most other navigation algorithms. This paper discusses how this is achieved by placing RFID tags in the 3-D space so that the lines linking their projections on the ground define the ldquofree waysrdquo along which the robot can (or is desired to) move. The suggested algorithm is capable of reaching a target point in its a priori unknown workspace, as well as tracking a desired trajectory with a high precision. The proposed solution offers a modular, computationally efficient, and cost-effective alternative to other navigation techniques for a large number of mobile robot applications, particularly for service robots, such as, for instance, in large offices and assembly lines. The effectiveness of the proposed approach is illustrated through a number of computer simulations considering testbeds of various complexities. View full abstract»

    To fully reach its potential, virtualized reality needs to go beyond the modeling of rigid bodies and introduce accurate representations of deformable objects. This paper explores neural networks and vision-based and tactile measurement strategies to investigate the intricate processes of acquisition and mapping of properties characterizing deformable objects. An original composite neural network framework is applied to guide the tactile probing by clustering measurements representing uniform elasticity regions and, therefore, direct sensors toward areas of elasticity transitions where higher sampling density is required. The network characterizes the relationship between surface deformation and forces that are exemplified in nonrigid bodies. Beyond serving as a planner for the acquisition of measurements, the proposed composite neural architecture allows the encoding of the complex force/deformation relationship without the need for sophisticated mathematical modeling tools. Experimental results prove the validity and the feasibility of the proposed approach. View full abstract»

    Current authentication systems suffer from many weaknesses. Textual passwords are commonly used; however, users do not follow their requirements. Users tend to choose meaningful words from dictionaries, which make textual passwords easy to break and vulnerable to dictionary or brute force attacks. Many available graphical passwords have a password space that is less than or equal to the textual password space. Smart cards or tokens can be stolen. Many biometric authentications have been proposed; however, users tend to resist using biometrics because of their intrusiveness and the effect on their privacy. Moreover, biometrics cannot be revoked. In this paper, we present and evaluate our contribution, i.e., the 3-D password. The 3-D password is a multifactor authentication scheme. To be authenticated, we present a 3-D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions toward the objects inside the 3-D environment constructs the user's 3-D password. The 3-D password can combine most existing authentication schemes such as textual passwords, graphical passwords, and various types of biometrics into a 3-D virtual environment. The design of the 3-D virtual environment and the type of objects selected determine the 3-D password key space. View full abstract»

    Ferroelectrics are suitable for the realization of sensors because their characteristics depend on modifying quantities such as temperature, electric fields, and pressure. The dependence of the dielectric and pyroelectric constant of ferroelectric materials on temperature is large and close to the Curie temperature, and this behavior can be exploited for the realization of capacitive sensors with high sensitivity in such a range of temperature. In this paper, a convenient solution for the investigation of the dielectric and pyroelectric coefficients of a ferroelectric device is discussed, along with a characterization tool developed to measure them. The architecture adopted was developed to study the aforementioned material properties up to the Curie temperature. A general-purpose data acquisition card and instruments usually available in research and educational laboratories were used, thus guaranteeing the low-cost feature, easy reproducibility, and flexibility.

    A microwave coherent homodyne and polarimetric ground surveillance Doppler radar is employed for collecting the radar returns from moving objects. Nonstationary nonlinearly frequency-modulated and multicomponent backscattered signals are analyzed and described as a sum of Doppler frequency-shifted polynomial chirp-like components. Instantaneous frequencies corresponding to the radiation backscattered by the different parts of a moving spatially distributed object are extracted from the time-varying bimagnitude estimates of transient sample sequences separated from the total received signal by a sliding window and projected into the time-frequency (TF) domain. Experimental investigations demonstrate a clean recovery of evolutionary phase-coupled harmonics for such targets as a swinging metallic sphere or a walking human. The computed TF distributions can be used in radar automatic target recognition systems to retrieve new data for the classification and recognition of ground moving objects. View full abstract»

    Nondestructive testing techniques for the diagnosis of defects in solid materials can follow three steps, i.e., detection, location, and characterization. The solutions currently on the market allow for good detection and location of defects, but their characterization in terms of the exact determination of defect shape and dimensions is still an open question. This paper proposes a method for the reliable estimation of crack shape and dimensions in conductive materials using a suitable nondestructive instrument based on the eddy current principle and machine learning system postprocessing. After the design and tuning stages, a performance comparison between the two machine learning systems [artificial neural network (ANN) and support vector machine (SVM)] was carried out. An experimental validation carried out on a number of specimens with different known cracks confirmed the suitability of the proposed approach for defect characterization. View full abstract»

    Voltage and current waveforms produced by several power systems are often characterized by a wide spectrum that contains numerous components, namely the fundamental, harmonics, and interharmonics. They can be properly analyzed through discrete Fourier transform (DFT)-based methods only if they remain stationary in time; in fact, in the presence of nonstationary components, DFT-based approaches do not grant reliable results because of the absence of a well-defined periodicity interval. The digital signal processing method proposed in this paper aims at analyzing a large category of nonstationary signals observed in power systems. It is capable of analyzing waveforms produced by power systems that seemingly operate in steady-state conditions, in which time-varying components represent anomalies, as well as waveforms generated by some power apparatuses, which supply nonstationary waveforms by design. The wide range of applicability of the proposed method is granted by a suitable processing scheme, including distributed filtering and phase unwrapping operations. Distributed filtering operations are performed to distinguish and separately analyze the major components contained in complex waveforms. Phase unwrapping operations are needed in the presence of nonstationary components characterized by heavy drifts and/or large swings in frequency. View full abstract»

    As complex very-large-scale integration circuit testing using external automatic test equipment is becoming increasingly expensive, built-in self-test (BIST) is an alternative technique that can significantly reduce the cost of testing. On the other hand, artificial immune systems have been considered as one of the most promising nature-inspired techniques used for novelty detection systems. One of the main features of such systems is self-nonself discrimination, which enables the body to distinguish any foreign cell from the body's own cell. In this paper, based on the principles of self-nonself discrimination, an immune-based output response analyzer for BIST is presented. Using the proposed scheme, the evaluation of the circuit under test (CUT) is performed by a set of immune-based detectors that are capable of detecting faulty output responses. Since the number of detectors is proportional to the hardware overhead consumed by the scheme, it is also presented as an optimization algorithm to reduce the number of detectors. Using the reduced set of immune-based detectors, zero aliasing is achieved, and, in addition, the evaluation of the CUT is performed during the test. The experimental results show the effectiveness of the proposed scheme. View full abstract»

    A new AC-DC comparator system of 20-1000 V has been developed at the National Metrology Institute of Japan (NMIJ) for the calibration of ac-dc thermal voltage converters (TVCs), which are used as national ac-dc transfer standards. The ac-dc transfer differences of high-voltage transfer standards were evaluated by a traditional step-up procedure. The voltage dependence of the ac-dc transfer difference was observed in the earlier step-up procedures over 300 V, as reported by the latest international intercomparison. The experimental results for high-voltage TVCs with several different range resistors at the NMIJ suggest that the voltage dependence may primarily be caused by input connectors of range resistors and the change in the resistance value of the resistor and TVC modules due to heating from resistors. This paper describes the voltage dependence improvement of ac-dc transfer differences over 300 V at the NMIJ. View full abstract»

  • Evaluation and Analysis of Heuristic Techniques for Vector Ordering of VLSI Test Sets

    Vector ordering is an essential task in testing very large scale integration systems because it affects this process from two perspectives: 1) power consumption and 2) correlation among test data. The former feature is crucial and, if not properly controlled, may result in permanent failure of the device under test (DUT). The latter feature is also important because correlation is captured by coding schemes to efficiently compress test data and ease memory requirements of automatic test equipment (ATE) while reducing volume and lowering test application time. Vector ordering, however, is NP-complete. This paper presents an evaluation of different heuristic techniques for vector ordering using the 1985 and 1989 IEEE International Symposium on Circuits and Systems (ISCAS85 and ISCAS89, respectively) benchmark circuits in terms of run time and solution quality. For this application, it is shown that the best heuristic technique is not the one based on the famous Christofides or Lin-Kernighan criteria but on the multifragment technique. It has been shown that the selection of an appropriate heuristic can lead to an increase in the compression ratio of up to 178% and a reduction in the power consumption during test of up to 46%.

    This paper describes a sequential phase-shift stroboscope and a subpixel imaging system that is able to measure with high resolution weak in-plane harmonic motions, such as those of microelectromechanical systems (MEMS). The synchronization of both MEMS stimulus and light strobe can be obtained by either using the camera output frame signal or driving the external trigger of the camera, depending on the operation principle of the camera. Experimental results concern a small silicon cantilever resonator excited in its first and second vibration modes and a quartz tuning fork. Two optical configurations have been developed. The first one is based on the use of a macroobjective for large fields of view with micrometer resolution displacement measurement, and the second is based on an optical microscope for weak amplitude vibration measurements with a resolution down to a few nanometers. The whole logic unit of the stroboscopic signal generator is implemented into a low-cost field-programmable gate array, thus offering high flexibility. View full abstract»

    A growing number of measurements in the commercial and industrial sectors need to refer to traceability to national and international standards. Instrument and reference standard calibration is resource and time consuming. Since many available digital instruments are provided with some communication interfaces and Internet-enabled metrology has rapidly been developing in recent years, it is possible to create an actual remote calibration system with remote control capabilities. This approach addresses a wide range of possible applications that can drive many kinds of different devices and can be easily upgraded. This paper focuses on some of the security problems regarding remotely executed Internet-enabled calibration processes. View full abstract»
