Study of an Innovative Approach to IoT Based Human Activity Recognition | Chapter 19 | Leading the Charge: A Guide to Management, Entrepreneurship and Technology in the Dynamic Business Landscape Edition 1

Recognizing human activities is vital for numerous contemporary applications rooted in the Internet of Things (IoT) framework, spanning from the creation of intelligent video surveillance setups to the advancement of robotic assistants for the elderly. Recently, there has been significant exploration into machine learning algorithms to enhance the recognition of human activities. Despite these research endeavors, there remains a notable dearth of studies focusing on efficiently recognizing complex human activities, particularly those involving transitions, and no research has been conducted to assess the impact of noise in training data on algorithm performance. This paper addresses these gaps by presenting an innovative activity recognition system centered on a neural classifier with memory capabilities, designed to optimize the classification of both transitional and non-transitional human activities. Utilizing unobtrusive IoT devices such as accelerometers and gyroscopes integrated into widely-used smartphones, the system effectively identifies human activities [1,2]. The key feature of the proposed system lies in leveraging a neural network augmented with short-term memory to retain information about preceding activities' characteristics. Experimental validation demonstrates the reliability and accuracy of the proposed system compared to state-of-the-art classifiers, highlighting its robustness in handling noisy data.

Investigation of the Gas Sensing Potential of Electrospun Expanded Polystyrene/ Reduced Graphene Oxide Nanofiber Composites | Chapter 1 | Chemical and Materials Sciences - Developments and Innovations Vol. 2

 

The gas sensing potential of electrospun nanofiber composites consisting of expanded polystyrene (EPS) and carbon-based nanofillers was investigated in this study. The nanofiber composites of expanded polystyrene (EPS) and reduced graphene oxide (RGO), EPS and carbon black (CB), and hybrid EPS/CB/RGO were produced by solution mixing followed by electrospinning. The surface morphologies of the developed nanofibers were studied with SEM, and the percolation threshold was determined with Keithely 2000 multimeter with four-point probes. The gas-sensing behavior was investigated in a gas-sensing unit. The SEM micrographs revealed long, uniform, and continuous nanofibers without beads or spindles. Homogenous dispersion of the nanofillers in the polymer matrix was also observed. Low percolation thresholds of between 0.07 and 0.2 wt.% were observed for the EPS/RGO composite and 2.0 wt.% for the EPS/CB composite. EPS/RGO sensor exhibited good stability but moderate sensitivity on exposure to the analyte gases. The hybrid composite; EPS/CB/RGO showed improved sensitivity than the others and comparable stability to EPS/RGO. The EPS/CB suffered from instability in response as a result of variations in baseline resistance. A rapid response time of 19s and a short recovery time of 20s were recorded with EPS/CB/RGO exposure to ethanol. The EPS/RGO sensor shows good linearity and reproducibility with a regression coefficient of 0.8975 with ethanol and 0.961 with toluene.

Determination of Five-Number Summary Method for Fault tolerance in Wireless Sensor Network | Chapter 07 | Innovations in Science and Technology Vol. 5

 A wireless sensor network is a collection of sensors that perceive data and take action in response to it. Wireless sensor and actor networks (WSANs) are made up of a collection of sensors and actors that are connected via a wireless media. The data is sensed by the sensor node, which then passes it on to the actor. The action is carried out by the actor in accordance with the data. Sensor nodes in a wireless sensor and actor network are constrained by hardware and software. As a result, faults in both the sensor and the network are possible. However, some study focuses on the connection fault without taking into account the data sensing defect. As a result, the node may detect inaccurate data and take the wrong action. The Five Number Summary Method for Fault Tolerance (FNSMFT) could be utilised to overcome this problem. In the future, we propose combining an intrusion tolerance approach with FNSMFT to provide sufficient security. The INtrusion-tolerant routing protocol for wireless SEnsor Networks (INSENS) builds tree-structured routing for WSANs in a secure and efficient manner. An invader can inflict damage to INSENS, but it can be tolerated.

Study on the Development of a MEMS Hotplate-based Photoacoustic CO2 Sensor | Chapter 08 | Novel Perspectives of Engineering Research Vol. 5

 Instead of using a micro-electro-mechanical system (MEMS) hotplate for metal oxide semiconductor (MOS) or nondispersive infrared (NDIR) gas sensing, a photoacoustic (PA) hotplate was used. This MEMS hotplate PA carbon dioxide sensor was created using a low-cost MEMS microphone. This is the first time, to the authors' knowledge, a MEMS hotplate and a MEMS microphone have been combined for use in gas sensing with a high modulation frequency. In comparison to the MEMS microphone employed in this study, NDIR sensors use far more expensive photodetectors. MEMS hotplates and microphones have a number of attractive characteristics, including low power consumption, small size, and low cost. Metal oxide sensors and infrared emitters for gas sensing frequently use micro hotplates. Low power consumption, small size, and low cost are all desirable qualities of MEMS hotplates and microphones. As a blackbody, the hotplate is a good infrared emitter, appropriate for detection in the absorption band. Despite the large loss of radiation power due to the high modulation frequency, the remaining/reduced power radiation power was still sufficient to excite molecules for the formation of PA signals. The sensor's temperature study revealed that the PA signal diminishes as the temperature rises, implying that temperature effects must be compensated for. This research provides an alternative optical gas sensing system that is less expensive than traditional NDIR sensors and uses easily mass-produced components, making it a vital addition to the fight against air pollution and global warming.

Evanescent Wave Fiber Optic Sensor for Detection of Fe+2 Using LED Source | Chapter 11 | Advanced Aspects of Engineering Research Vol. 16

 Based on the evanescent wave fibre optic absorption approach, a cost-effective and sensitive chemical sensor for the detection of Fe+2 has been developed. In the sensing mechanism, a high-quality LED source is used. As the sensing arm, a multimode sensor grade plastic clad silica (PCS) fibre is used, with the centre cladding portion removed to interact with the surrounding region (Fe+2 ions). In this experiment, the unclad area of the PCS fibre is utilised as a sensing element. For the detection of Fe+2 in water, the sensor developed is very sensitive over a dynamic range of concentrations from 0.1ppm to 100ppm.

Advances in Nanotechnology: Development of Sensing Devices with Doped Thin-films Perovskites Materials| Chapter 6 | Emerging Trends in Engineering Research and Technology Vol. 8

 Thin films of gas sensitive materials based on the SrFeO2.5+x nonstoichiometric perovskite family were

deposited onto an interdigitated gold electrode construction device by room temperature pulsed
excimer laser deposition (RT-PLD). Two films sensors based on the SrFe
1-yCoyO2.5+x oxides
perovskite family, with y=0.75 and 0.5 respectively, have been presented. Their ability to very quickly
respond to the presence of low concentrations of methanol makes them attractive for construction of
methanol sensing devices, as gases monitoring sensors for either environmental applications, or as
an automated feedback sensor for concentration measurement and control in a micro direct methanol
fuel cell (μ-DMFC) power supply.
