The procedure includes an offline processing for body-IMU calibration and an online tracking and identification of lower body motion. We proposed an optimal movement pattern for the body-IMU calibration method from our previous work. Here, in order to reproduce real extreme situations, the focus is on the movements with high acceleration. For such movements, an optimal orientation tracking approach is introduced, which requires no accelerometer measurements and it thus minimizes error due to outliers. The online tracking algorithm is based on an extended Kalman filter(EKF), which estimates the position of upper and lower legs, along with hip and knee joint angles. This method applies the estimated values in the calibration process i.e. joint axes and positions, as well as biomechanical constraints of lower body. Therefore it requires no aiding sensors such as magnetometer. The algorithm is evaluated using optical tracker for two types of exercises: squat and hip abd/adduction which resulted average root mean square error(RMSE) of 9cm. Additionally, this work presents a personalized exercise identification approach, where an online template matching algorithm is applied and optimised using zero velocity crossing(ZVC) for feature extraction. This results reducing the execution time to 93% and improving the accuracy up to 33%.","PeriodicalId":72028,"journal":{"name":"...

Worldwide sustainable development is required to preserve a good quality of life. Energy efficiency is one of the most relevant issues that the scientific community and society must face along the next decades. This paper focuses on reviewing and noting the main factors which impact the optimization of electrical energy efficiency in Smart Buildings, including distribution, consumption analysis, strategies and management. Smart grids and smart buildings are playing a key role in the definition of the following generations of cities where the impact of energy consumption on the environment must be reduced as much as possible. Notwithstanding, all the factors impacting the production and distribution must be also taken into consideration by energy production companies and distribution companies as well. Green energies are being introduced in smart cities and buildings, only slower than required, and in general, focusing on the consumption side asking for higher performance monitoring and control techniques, and encouraging to incorporate energy harvesting initiatives to improve the overall efficiency. In this paper, the major target is pointing out all the relevant factors influencing smart building energy efficiency, up to the consumer side and, at the same time, paying attention on distribution and generation issues and, specifically, available communication standards, technologies, techniques, algorithms, which enable high performance systems to optimize energy consumption and occupant comfort.","PeriodicalId":72028,"journal":{"name":"...

This paper presents a model of a timely prehospital emergency management system that can be implemented as an interface to an Internet of Things (IoT) environment. This work presents the necessary stages for prehospital emergency environments, where many factors may make the timely manage ment of emergency systems very difficult. The proposed model is based on an Algorithmic State Machine ( ASM) that can be implemented in either hardware or software, providing an embedded system interfa c for IoT. Moreover, this paper provides a timing analysis for either a single emergency event or multiple sim ultaneous emergency events.

We design and implement MultiSense, a novel fall detection system, which has the following desirable features. First, it does not require the human to wear any device, therefore it is convenient to seniors. Second, it has been tested in typical settings including living room and bathroom, and has shown very good accuracy. Third, it is built with inexpensive components, with expected hardware cost around $150 to cover a typical room. Therefore, it has a key advantage over the current commercial fall detection systems which all require the human to wear some device, as well as over academic research prototypes which have various limitations such as lower accuracy. The high accuracy is achieved mainly by combining senses from multiple types of sensors that complement each other, which includes a motion sensor, a heat sensor, and a floor vibration sensor. As the activities that are difficult to classify for some sensors are often not difficult for others, combining the strength of multiple types of sensors brings the performance to a level that can meet the requirements in practice.","PeriodicalId":72028,"journal":{"name":"...

It is important to detect the disease at its very early stage. However, the distinction of later infestation stages is also practical. We proposed to apply gas sensor array measurements of beehive air as the source of information which may be useful for this kind of assessment. Honeybee infestation was classified into three categories: ‘low’, ‘medium’ and ‘high’, two categories: ‘low’ and ‘medium to high’, and another two categories: ‘high’ and ‘medium to low’. Responses of gas sensor array to beehive air were used as the input data of the classifier, which was trained to distinguish the categories. The results of the analysis demonstrated that category ‘low’ was determined most effectively, with an error rate of about 10%. Category ‘high’ was most difficult to determine. In this case the lowest error rate was about 20%. Based on our analysis, the approach based on binary classification was favoured and SVM outperformed ensemble of classification trees. It was found, that first several minutes of gas sensors exposure to beehive air were sufficient to attain effective classification. The presented method of varroosis determination, based on beehive air sensing with gas sensors is innovative and has high potential of application in beekeeping.","PeriodicalId":72028,"journal":{"name":"...

This paper proposes a method to enhance the quality of data obtained from low-cost atmospheric pressure sensors using a machine learning algorithm to predict the error behaviour. By using the extremely Randomized Trees algorithm, a model was trained with a reference sensor data for temperature and humidity and with all low-cost sensor datasets that were co-located into an artificial climatic chamber that simulated different climatic situations. Fifteen low-cost environmental sensor units, composed by five different models, were considered. They measure – together – temperature, relative humidity and atmospheric pressure. In the evaluation, three categories of output metrics were considered: raw; trained by the independent sensor data; and trained by the low-cost sensor data. The model trained by the reference sensor was able to reduce the Mean Absolute Error (MAE) between atmospheric pressure sensor pairs by up to 67%, while the same ensemble trained with all low-cost data was able to reduce the MAE by up to 98%. These results suggest that low-cost environmental sensors can be a good asset if their data are properly processed.","PeriodicalId":72028,"journal":{"name":"...

They offer new advances in the fields of smart structures and health monitoring. All serial optic al sensor networks rely on multiplexing techniques that provide huge amounts of sensors in a single optical fiber . Wavelength-division multiplex (WDM) which has been established in many applications, is restricted to the spectral width of the used light source that needs to be shared by several non-overlapping fiber-Bragg-g ratin (FBG) spectra. Time-division multiplex (TDM) uses short impulses and relies on different sensor rou nd trip delays to distinguish each single FBG. These short impulses and long round trip times lead to a low si gnal-to-noise ratio (SNR). Optical frequencydomain reflectometry (OFDR) offers a high spatial resolutio n of FBGs but only within a short fiber length. This contribution deals with a code-division multiplex (CD M) interrogation technique that provides numerous sensors in a single optical fiber, a better SNR, and a long rang e of distributed sensing points. It requires codes with good autocorrelation behavior which is characte ized by certain criteria. The detectable criteria are limited which narrows significantly a search for best pos sible codes for the interrogation system. In this contribution, practical implementation limits such as the rigger timing and the achievable SNR are studied. Based on the introduced SNR definitions for CDM and WDM system , a direct comparison is possible and it shows the superiority of the proposed CDM scheme. A networ k with 25 sensors operating at the same wavelength can provide a 2 .67 dB improvement compared to WDM","PeriodicalId":72028,"journal":{"name":"...
