An expansion is introduced to a technique for emphasising sound signals from one particular area that is surrounded by undesired noise sources. The proposed expansion allows sound signals to be extracted from areas located in different positions. The previous method uses multiple fixed beamformers to estimate the power spectral densities of two-dimensional areas and thus, calculate the necessary gain coefficients used to emphasise sources within the target region. The proposed expansion adjusts the beamformer directivity, in order to change the location of the target region. Validation was achieved by testing the performance within an anechoic chamber using two Kinect sensors equipped with microphone arrays. The expansion achieved noise attenuation and signal distortion performance equivalent to that of the previous method in different target regions.

This paper presents an overview of Bug algorithm family local path planning methodology timeline. The Bug algorithm approach detects the nearest obstacle as a mobile robot moves towards a target with limited information about the environment. It uses obstacle border as guidance toward the target. The robot circumnavigates the obstacle till it finds certain condition to fulfill the algorithm criteria to leave the obstacle towards target point. In addition, this paper presents the performance of a new path planning approach, PointsBug algorithm. The performance of PointsBug was compared to TangentBug in term of duration and distance in various types of environment. TangentBug was selected as the algorithm to be compared to as it is the best performing Bug family algorithm that uses a range sensor similar to PointsBug. The outcomes of the research indicates that PointsBug have outperformed TangentBug in average speed in the selected environment as described in this paper.

A solar panel based sensor for automatic recording of practical insolation data at North Latitude 35.122196° and West Longitude -89.934553° has been developed. To implement this, a detailed, application oriented, solar panel model has been tested. This modeling has been divided into categories based on both technological characteristics such as cell and panel construction and disciple orientation such as thermal, electrical, optical, and mechanical. Emphasis has been on performance at maximum collection efficiency. This document addresses efficiency from the electrical output side rather than the optical input side. Emphasis is on effective coupling to load, balanced against collection efficiencies, so that sensor calibration constant is nearly constant. Partial obscuration and cost impacts are addressed.

This paper presents a new design and achievement of Leaky Coaxial Cable (LCX)-based intrusion-sensing techniques. LCX radiates microwaves from slots milled on the outer conductor. This sensor can detect an intrusion object by measuring the variation of received signal. LCX has two types of emitting modes, radiation mode and surface mode. The microwave radiates to far field in radiation mode. On the other hand, the microwave exists only around the LCX in surface mode. Although the conventional LCX-based sensor operates the LCX in only one mode to detect and classify an object, this paper introduces a simultaneous sensing technique using these two modes. Comparing the signals in both modes, the classification of an object can be estimated. The theory of the emitting modes of LCX and the developed sensor prototype are described. Experimental results are presented to show that the proposed sensing techniques are valid.

Multiferroic materials represent a very attractive class of materials due to the coupling between their electric and magnetic orders. A recent paper has demonstrated that a thin film of BDFO shows a good magnetoelectric coupling. Based on such a peculiarity, multiferroic composites can be successfully used to realize sensors of both electric and magnetic fields. This work reports two different ways to realize an E-field and B-field sensor with a thin layer of BDFO. The first approach shows as a single multiferroic device can be used as sensor, while the second approach exploits a coupled system made by three multiferroic devices. The multiferroic device models are presented together with the electronic circuits used in the simulations.

Humans will replace human labor with new robotics technologies, especially where humans can be placed in danger situations or task domains. Evolving sensor and robotic technologies allow the transfer of humans from mundane, dangerous or difficult tasks, leaving robots to apply their specific capabilities to replace human's daily routines or hazardous tasks. Commonly, humans work in teams to resolve difficult scenarios, such as the aftermath of some natural or man-made disaster. Communication between each and every team member is critical to resolve relief efforts or remediation, in most disasters. This research presents robotic technology developed to remediate the long lead time to re-establish or develop network infrastructure in the case of a disaster situation. The specific application and test domain of this research, is with fire fighting.

This paper introduces a novel notion in the application protocol design paradigm for wireless sensor networks (WSNs). The traditional approaches of designing application protocols tend to focus primarily on developing the protocols first, and then using them on different topologies for implementation. We, however, argue that the logical topology of WSNs should be considered before designing application protocols. The argument is made on the basis that the logical topology of WSNs dictates the communication abstraction, the structure, and the hierarchy of the network. Thus, a well-designed logical topology helps in minimising the constraints of the WSNs and provides benefits to design various application protocols. In this paper we demonstrate how a well-designed logical topology influences the performances of protocols developed in WSNs. In doing so, the logical structure and the communication abstraction of the logical topology are used to design a number of application protocols, and their performances are evaluated.

Emergency responses must utilize all information sources available to the emergency operations centers. University campuses are overflowing with information sources due to their infrastructure of information technology (IT). While serving a student body of thousands and sometimes 10s of thousands, every operation in a university involves an IT enterprise system. While enterprise systems store and operate on vast amounts of data about the “happenings around campus”, they are still disparate data systems with no integrated view. Furthermore, most systems operate on and store same information about campus and people while using various data models appropriate to their operational needs. In this paper, we propose an industry standard that can enable treatment of data sources as enterprise sensors in an emergency sensor network towards an integrated emergency management portal. The standard is IF-MAP (interface for metadata access point). IF-MAP is a technology suite with a thin client to enable a publish/subscribe communications paradigm that can integrate disparate data sources for a facilitation of data exchange in speeding emergency decision processes. We have implemented integration of sensor data feeds from the card access system, video feeds, and general facilities information at the University of Houston.
