Recent developments and advances on electronics and wireless telecommunications have enabled researchers to design and produce low-power and small sensors with reasonable prices which can be used for various applications. Wireless multimedia sensor networks are a new subset of WSN family which is capable of doing operations such as receiving multimedia information, i.e. video, sound, photo and numerical data from the surrounding environment, processing them and transmitting them. Due to high transmission rate and the explosive feature, the transmission of video flows in WSNs concerned with several challenges. Congestion also leads to the loss of packets and costly retransmission of packets. Consequently, the limited energy of the sensor nodes is wasted. Accordingly, in this paper, using fuzzy logic, a new congestion control method was proposed for these networks. In the proposed method, congestion announcement and control are carried out by using three main parameters, i.e. the remaining energy level of the node, load density and accessible detection bandwidth. The results of evaluations, done via OPNET 11.5, indicated that using the proposed method led to an average delay reduction in packet arrival. Also, less energy of the nodes is consumed and network lifetime is enhanced. Multimedia is used for novel approaches such as the followings: communications, commerce, education, entertainment, personal locator services, advanced health care, control systems, traffic avoidance and execution and in Information Technology.

A reconfigurable set of focal plane control electronics has been developed that can operate a broad range of advanced all-digital focal planes in space- and ground- based applications. To date, the reconfigurable focal plane electronics (RFPE) have successfully operated 7 different state-of-the-art all-digital ROICs from multiple suppliers, including Teledyne Imaging systems, BAE, and others. The payload is approximately 7.9 '' x 4.5 '' x 7.6 '', is fully redundant, dissipates between 5 and 25 watts, depending on the sensor and application, and is user programmable after launch. The RFPE has been demonstrated operating sensors with aggregate digital output rates up to 33 Gbits/s, but it supports rates up to 50 Gbits/s. An integrated programmable micro-sequencer generator enables users to create and store dozens of complex image data collection scenarios and modify or add to those once on orbit. Lossy and lossless image compression, pixel level gain and offset (a.k.a. NUC) correction, frame co-adding, decoding/encoding of cyclical redundancy check sensor data, and bad pixel correction are a few of the image processing features that have been demonstrated to date. Bias sources are programmable and include over-voltage and over-current protection to safeguard mission critical image sensors. Enhancements under development include the addition of graphical processors and a large cache of solid state memory. This paper describes the current and planned capabilities of the RFPE payload.

This paper presents an adaptive neural-network optimal tracking control (ANOTC) scheme for permanent-magnet synchronous motor (PMSM) servo drive with uncertain dynamics via adaptive dynamic programming (ADP). The proposed ANOTC scheme consists of an adaptive steady-state controller, an adaptive optimal feedback controller and a robust controller. The adaptive steady-state controller is designed for attaining the targeted tracking response during the steady-state. The adaptive optimal feedback controller is designed for stabilizing the dynamics of tracking error at the transient in an optimal manner. Accordingly, critic and actor neural-networks are employed for facilitating the online solution of the Hamilton-Jacobi-Bellman (HJB) equation for approximating the adaptive optimal control laws via ADP method. Further, the robust controller is developed for compensating the approximation errors of neural-network (NN). Based on Lyapunov approach, the closed-loop stability of the PMSM servo drive system is proved to demonstrate that the proposed ANOTC scheme can ensure the system state tracking the targeted trajectory effectively. The proposed ANOTC scheme validation is performed via experimental analysis. From the experimental validation results, the PMSM servo drive dynamic behavior using the proposed ANOTC scheme can attain the optimal control response regardless the compounded disturbances and parameter uncertainties.

Resilience deals with the system capacity to adjust itself to face unexpected events by ensuring four activities that are: anticipation, monitoring, response and adaptation. In this work, we focus especially on how monitoring is a potential strategy to anticipate unexpected situations for enhancing resilience. We propose a solution for monitoring human-system interaction based on continuous, automatic and real-time model-based usability evaluation. The proposed monitoring proxy tool is able to log user activities, using Petri Net language, while interacting with the human-machine system. The identification of usability issues is carried out through detecting any deviation from what task model assumes comparing to user activities. This approach has been defined and applied using a simple case study: an automated speed control car system.

Non-ideal phase responses on electro-thermally actuated piezoresistive cantilever sensors have led the phase-locked loop (PLL) systems into difficulties for real-time sensing applications. These outcomes are caused by thermal-parasitic coupling from the actuating part to the sensing part. Minimizing or eliminating parasitic effects is necessary to obtain an optimized phase response. To realize this, we adjusted the voltage supply of the sensing part, which is in form of a full Wheatstone bridge (WB). By increasing the WB supply voltage (V WB), the phase response can be enhanced. Alternatively, a reference signal that differentially eliminates the parasitic parameter from the sensor output was employed. To investigate the resulting optimized phase response under real-time measurement conditions, two different microcantilevers were connected to an MFLI lock-in amplifier + PLL system (Zurich Instruments). Measurement results exhibited a good sensor performance under varying humidity and temperature conditions. © Published under licence by IOP Publishing Ltd.

Wireless sensor networks (WSNs) are a new and most recent technology which is used in many critical applications. WSN is a network which is deployable anywhere in the environment. Due to this nature of WSN, an unattended network is more probable for vulnerable and unavoidable attacks. WSN is comprised of huge different types of nodes which are distributed within the network. Some of the nodes have sensing technique for detecting unusual behaviour in the network. Detection and prevention mechanisms are used for securing the network, with the consideration of energy efficiency. Biometric-based system is most efficient way of detecting an intruder which is one of the major techniques of pattern matching. Since WSN is more probable vulnerable to various harmful security attacks as it has the nature of broadcasting the transmission data and has very low capacity of computation, an Intrusion detection system (IDS) is used to detect such mobile attackers or intruders. Intrusion prevention system (IPS) uses a mechanism which enables the reduction of consumption of energy in sensor nodes of WSN.

The processing of data maps in order to find the best solution to transverse between two points is a key task of an autonomous robot. The algorithm often used for this task must also define the computational power requirements of the embedded processor in the system to optimise the solution with the least number of steps. Low end processors can be used contrary to traditional computers. This paper presents a simplified path solving algorithm for known and unknown environments where the robot range is limited to the size of the map created within the computer internal memory. The map can be preloaded with obstacles expected to be encountered. Alternatively, the robot can be switched to discover mode, where information about its environment is gathered on-the-fly using a range sensor. Two path planning algorithms have been simulated in this study to analyse the most efficient execution to be implemented on the platform with a micro-controller with the A* algorithm showing the superior performance and lower computational cost in comparison with Djickstra.

A growing number of electric-field sensors and magnetic-field sensors are becoming commercially and federally available. However, there is a lack of compact sensor systems that integrate both modalities for more advanced sensing scenarios. The CCDC Army Research Laboratory has developed a “4-D Cube” sensor which precisely measures the local 3-D magnetic field and 1-D electric field at frequencies between 30 Hz and 32 kHz. By using a non-metallic transducer for the electric-field sensor, and three loop sensors without a ferrite core for the magnetic-field sensors, we minimize cross-axis and cross-modality field distortion, even when these sensors are placed in close proximity to each other in an array. This paper will cover the quasi-static field theory behind the design of the complete sensor system, and characterization results of the electric- and magnetic-field sensors for frequency response and noise spectral density. The 4-channel analog sensor is approximately 200×200 ×130 mn, weighs under 0.5 kg, and consumes less than 50 mW during full operation. Cross-axis effects have been measured to be ≤ 5%. The noise spectra is and over most of the 32-kHz frequency range, and all sensors have dynamic range regarding single-tone signals.

Road car transport is today the main species of cargo and passenger transport. However, car transport is accompanied by large negative effects with adverse environmental impacts. Therefore, it is an effort to shift part of the transported costs to rail transport. But the problem is vibrations which created the passing vehicles. The vibrations are transmitted over the rails and the railway infrastructure into the rock environment. These vibrations can adversely affect buildings around the railroad. This article presents a comparison of vibration measurements using a classical commonly used seismic sensor and innovative fiber-optic interferometric sensor. Presented results are based on the real measurements of train traffic. Presented results can serve as a basis for mathematical models which predict the future load of objects in the vicinity of railway tracks.
