The EKG signals are inherently weak, and noisy signals built of many variable components due to many environmental factors in which it may include but is not limited to changes in body temperature, body movement, and line frequency 50/60 Hz. The ECG signal cannot be conditioned, amplified, nor reproduced directly and therefore, digital filtering techniques with adjustable window are used in this paper. The paper analyses several models of Finite Impulse Response (FIR) filters of low-pass and high-pass and their aspects in term of response time, gain, and harmonic distortion, and rejection to determine the best band-pass filtering model to reproduce an ECG signal that closely resembles the actual Heart function of a patient. A hybrid filtering model is proposed and experimentally tested. Mean square error (MSE) is used to estimate a signal goodness. MATLAB environment has been used for the experimental part to simulate the signals. This research work has been considered in the context of a larger project that consists of a complex wearable health monitoring system comprising biosensors, wireless communication modules and links, control and processing units, medical shields, wearable materials and advanced algorithms used for decision making and data extracting. The proposed filtering technique is useful in the medical data preprocessing phase.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131773661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all these studies, brain activity is considered as a simple modality of providing a system or a device with knowledge from human interactions. Although this simple transfer of information represents a significant development since BCI also integrates brain signals with data from sources like speech, eye gaze, gestures, facial expressions, body postures or physiological measures like heart rate, blood pressure or electrodermal activity. This fusion creates a context-aware and a context-dependent interpretation of the brain signals but represents in the same time a challenge for the neuroscience researchers that must process and represent all this data for clinical or non-clinical applications. BCI has become an addictive and powerful research domain offering a wide range of applications from cognitive load in educational tasks and gaming to automotive and assistive technology.

On the consumer side, DD methods can be divided into two control options: load shifting and load shedding, with different control approaches. At the distribution grid level, a demand dispatch control framework was proposed. A multi-criteria optimization problem was formulated, considering the 3 involved actors: the utility, the energy market and the consumer. The testing scenario was built, based on the Romanian power system context with data considered from the transport operator and the energy market.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124712700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the medical crew when they need to intervene takes very high risks being forced to move through cross-fire. Being aware of the status of every soldier in battle gives a great advantage in terms of prioritization. Besides the military applications, there is a visible need of new methods of determination of the vital signs. Discovering such new methods offers the advantage of versatility. Wearables will no longer be constrained by where they should be worn, or there will be enough methods of analyzing the vital signs that it will be easier to find a method of wearing it that suits the need. Because the IMU sensors are used in every device that consists of a movement analyzing feature, searching for new applications to use them brings a big gain. In this paper, we analyze the possibilities of using IMU sensors in detecting the vital signs of a person, and the results obtained will represent a starting point for the implementation of a solution for monitoring the vital signs of soldiers.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"AES-7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126513241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we provide a guideline going through all the steps from configuring the hardware setup to obtaining a clean dataset. We describe the data collection scenario design, the hardware and software employed in the process, the challenges that must be considered, data filtering and validation stage. This work stems from our experience in collecting the UPB campus driving dataset released together with this work.

This paper extends the work for the case of separable dictionaries, by modifying the Extended Renormalized Maximum Likelihood criterion to the 2D model and proposes an adaptation algorithm that almost entirely relies on the ITC score. Results in terms of mean size recovery rates are within 1 atom away from the true size, while representation errors are consistently below those obtained when applying dictionary learning with the known size.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"41 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116734362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
