There are many applications rely on the use of colour segmentation in image processing. The major challenge with colour segmentation is that there is no unique solution as each person perceives and segments the colours in images differently. The segmentation results are also heavily influenced by environment factors such as lighting conditions and noise levels. In addition, existing methods tend to focus on the segmentation stage alone and employ little to none for pre-processing. Thus it can be a challenge task to develop an efficient colour segmentation method. In this paper, a novel colour enhancement method is introduced to boost the colour saliency of the critical regions and to improve the consistency of segmentation results by maximizing chroma while preserving hue. Tests in various common colour models using Euclidean distance segmentation method have shown that images pre-processed with the novel colour enhancement method produced much more accurate and reliable colour segmentation results than images without the enhancement or enhancement using existing methods.

Wireless sensor networks have been found to be useful for detection of events like volcanic eruption, landslide, and agricultural crop stress. The problem of in-network data aggregation for binary event detection has been well studied in literature for multihop wireless sensor networks with tree topology. In this paper, we propose a novel Neural Network based distributed detection approach for multihop wireless sensor networks with mesh topology. As compared to the tree topology, the unidirectional mesh topology resembles more closely to a neural network wherein each sensor node has been modeled as a neuron in the neural network. An exhaustive analysis has been presented to compare the proposed approach with the existing approaches for tree topology along with their modified counterparts for the mesh topology. The simulation results depicts a substantial gain in the detection accuracy by the proposed neural network based data aggregation approach in wireless mesh sensor networks as compared to the other existing methods for tree and mesh topologies of the wireless sensor networks.

This paper describes the design and development of a sensing system to detect the nitrate concentration by using planar interdigital sensor immersed in the water sample. Water samples were prepared containing two different salts: Sodium Nitrate (NaNO3) and Ammonium Nitrate (NH4NO3) with the concentration ranging from 0.02 PPM to 10 PPM by using the serial dilution method. The water sample was tested by both the commercial equipment (LCR meter) and designed system. Although a difference was observed between these two results, the designed system shows a good linear relationship between the low concentration (0.02 - 0.5 PPM) of the water solution and the real part of the impedance. However, the relationship was changed from linear to logarithmic scale at the high concentration (0.05 - 10 PPM) of the water solution. The computational formula of concentration was formed from these results. This system has a potential to be used in-situ nitrate contamination detection with real-time monitoring.

This paper describes a new sensor system for an abdominal palpation procedure in traditional medicine. This sensor system uses a motion capture system and a thin film force/pressure sensor which enables to measuring the depth and the force/pressure at the same time during abdominal palpations. We customised the motion capture system, making it suitable for abdominal palpations, to prevent a physician from being distracted and to eliminate blind spots. We fabricated a detecting circuit for the force/pressure sensor which uses a Bluetooth low energy module and which is powered by a coin cell battery. The circuit enables mounting the detecting circuit on a glove. In addition, we developed a user interface application which is easy to use and which records the information on abdominal palpations on a personal computer. The abdominal palpation sensor system should transfer the diagnostic criteria to young physicians more easily and appropriately in traditional medicine.

The Wireless Sensor Network (WSN)-based pipeline monitoring systems are expected to have long life time in order to make their deployment cost-effective. In reality, wireless transceivers are considered one of the main consumers of energy in individual sensor nodes of WSNs. The duty cycling technique which puts transceiver module into sleep state for the majority of sensor node's operating time is considered a highly effective method to reduce energy consumption. In this paper we present the use of Wake-on-Radio (WoR) for reduction of used energy and conducted power consumption experiments using CC430-based WSN nodes. The results show promising performance improvement when using WoR in the CC1101 radio transceiver of CC430. Then, an adaptive duty cycle algorithm based on the WoR functionality, which enables sensor nodes to dynamically adjust their WoR duty cycles according to the real-time wireless channel conditions in achieving reduced power consumption, was proposed.

This paper reports the implementation of a silicon-based infrared (IR) multiband pass filter (BPF) on an uncooled microbolometer IR focal plane array (IR-FPA), both of which are fabricated by the standard CMOS process. IR spectroscopy has been widely used as a sample identification technique, exploiting the fact that each molecule structure has a unique spectral feature. Using IR-BPF and IR-FPA, a low-cost and compact IR-spectral imaging system is realized. The microbolometer IR-FPA exhibits broad spectral response sufficient to cover the IR-region from the mid-infrared (3 μm) to far-infrared (8 μm~), which is broader than the coverage of conventional non-silicon-based photodetectors such as mercury cadmium telluride. Single-band images of invisible gases such as ethanol vapor and CO2 in breath are obtained with the IR-FPA. For multiband imaging, a guided-mode resonance IR filter is fabricated by patterning aluminum (Al) layer of 100 nm thickness on a silicon-on-insulator wafer. Measured peak transmittance wavelengths (λc) of square and hexagonal Al array are compared with results of rigorous coupled-wave analysis, as a function of the Al pattern period. The λc of 3.3, 3.9, and 4.4 μm are obtained at the pattern period of 1.8, 2.4, and 2.8 μm for the square array. In all cases, the λc slightly decreases for the hexagonal array. The full-width at half-maximum (FWHM) of each filter is approximately 200 nm for the λc of 4.4 μm, 400 nm for λc of 3.3 μm.

Continues health monitoring of healthcare facility environments is vital in maintaining their quality of service standards. This paper discuss a suitable hardware implementation using reconfigurable network nodes to setup such a network with monitoring facilities to measure carbon dioxide, carbon monoxide, methane, ammonia gas concentrations, light and noise levels, and people movement information within the facility. These information can be fused together to make vital decisions alerting the healthcare facility staff to attend to a particular location without having dedicated staff for continuous monitoring. This will help dedicating the healthcare facility staff for other important care duties while the wireless sensor network looks after the health of the facility environment.

A versatile measurement system has been designed and commissioned at CERN, which is based on a wire sensor in different modes of operation: the classical single-stretched wire mode, the oscillating wire mode employing frequencies well below the first natural resonance, as well as the vibrating wire mode where the wire is excited in the first or higher-order resonance conditions. In this paper, the main technical challenges and constraints of the wire methods are presented, together with the applications to locate the magnetic axis of a string of magnets on a common girder and to the measurement of multipole errors. Sources of uncertainty, stemming from the wire motion unsuitability, are discussed, different wire motion transducers are compared, and the effect of background fields and environmental effects is studied.

This paper proposes a Sensing Service Framework for integrating Wireless Sensor Networks (WSN) and cloud infrastructure to impart climate alerts and perform climate analysis at reduced cost. This paper also provides a literature survey of related works on Sensor and Network level Virtualization. Factors that determine climate are humidity, temperature, wind speed, sun movement and so on. Drawbacks of prior work are sensor and network level virtualization not employed. The proposed work overcomes by deployment of WSNs components for many climate applications by employing virtual sensor and climate overlay approach. Sensing service framework monitors climate data by issuing Sensing Service and social media alerts. All these factors improve and provide climate updates to customers and climate analysts at reduced price.

Interest in sound interfaces is increasing because such interfaces do not need advanced knowledge about particular devices, nor do they require physical operation. However, such interfaces are difficult to use because the general living environment often contains background noise. In order to solve this problem, sound separation systems that use a microphone array sensor have been proposed. In previous work, this microphone array sensor was a small system that considered only two-dimensional (2-D) directivity control. In this paper, we present the design of a spherical microphone array sensor with 3-D directivity. This 3-D directivity property is confirmed via an experimental evaluation.
