It is complex structure which consists of the three nuclei. Human striatum neurons firstly can be visually classified into two types (spiny and aspiny), but further classification recognizes two subgroups of spiny, and three subgroups of aspiny neurons. The original goal of this study is to confirm or improve the existing division of striatal neurons using two main techniques of cluster analysis. A total of 175 two dimensional images of aspiny neurons have been captured by the light microscope, and recorded with accompanying digital camera. Specialized public software Image J has been used for both image reconstruction and measurement. Each binary image of the neuron have been quantified with apparent parameters of monofractal analysis. Hierarchical cluster analysis and k-cluster method classified two existing groups of aspiny cells into three classes. Moreover, the morphometric difference in all groups between two functional different nuclei were reported. To the best of our knowledge, the presence of neuronal types in the adult human neostriatum has thus far been established and described mainly with Euclidean parameters. Thus, the present study, quantifies cells with monofractal parameters only. In the present study, only two types of aspiny neurons were used. But two techniques of cluster analysis found three groups of neurons. This results need to be verified with same classification technique, but using different computational parameters. Finally, the present study offer vague conclusion regarding difference in cell types between two cores of dorsal lamina.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"30 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":"131808344","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}

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 many applications, within a CPS, mobile and wireless networks are used to realize the data transmission, conforming to the concept of Internet of Things (IoT). This facilitates interactions with several types of devices like sensors, RFID readers, mobile phones etc. Besides, Smartphones include important sensors as GPS, accelerometers, light sensors, phone camera etc. Based on such a foundation, different electronic services can be developed and provided for various types of clients. New research directions revealed the necessity to consider middleware architectures in CPS design. In this direction, Service Oriented Architectures (SOA) represents a paradigm that can be very efficient in designing specific layers of CPS. Web services are examples of SOA implementation, adequate for the requirements of the business environments. This paper presents a Cyber Physical Systems oriented e-business platform using Web services, which can be accessed through mobile and wireless networks, using Android OS Smartphones. A stock market exchange service was considered, as a relevant example of e-business. The time response of the SOAP and REST based Web service was evaluated, on LTE 4G and IEEE 802.11n channels, to determine which protocol is more efficient to increase the real time response capacity of the CPS oriented platform.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"100 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":"121120331","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}

Mobile robots have complex nonlinear dynamics and finding optimal controllers is generally a difficult task. We propose an enhancement of the classical genetic algorithm that seeks to improve search efficiency when dealing with multiple conflicting criteria. Our solution consists in an immunization mechanism. Using an updating Pareto front, we create adaptive vaccines to help the population strengthen its desirable features during evolution. Numerical simulations show that a significant improvement has been obtained in terms of required number of generations to reach a desired optimum. Moreover, the returned solutions offer more consistent closed loop performances when using the proposed Pareto-based immunization mechanism.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"2 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":"128337143","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}

Such systems vary over time due to external disturbances or unmeasured changes to which they are subjected. In this case, a simple PID controller cannot provide the desired response, unless the controller parameters are re-tuned. An adaptive control algorithm responds to this need. Moreover, to increase robustness, fractional order controllers are designed, being recognized for this property. Such control provides the entire process with good robustness and ensures good operation for major process changes.

Silver Digital Patients can be defined as seniors that master improved abilities of using digital technology in their daily activities, including in monitoring their health, who prove increased interest in having access to the best healthcare to preserve as much as possible their independence and health. An active, decent and safe life for seniors is at its best in their own homes; therefore, a remote health monitoring represents the most appropriate way to smooth the disruptive degenerative age-related factors, together with the important benefit of relieving the expenditures for senior institutionalizations. In this respect, emerging senior-centered technologies have the potential to provide a reliable support for building the most appropriate healthcare provision and environment. Internet of Health Things (IoHT) is a concept for a great variety of devices connected to the Internet that are able to gather a huge amount of diverse data - like health or environmental parameters - in order to keep a close remote watch on the patient, to improve the diagnose of his/her health status and to establish a better preventative healthcare. Edge computing brings the potential of improving the performance and responsiveness of IoHT by allowing the real-time collected data to be pre-processed closer to the source, which can be extremely important for time-sensitive health data in order to identify and trigger anticipatory or reactive health actions. This paper presents a case study -\" Non-invasive monitoring and health assessment of the elderly in a smart environment (RO-SmartAgeing)\" project - that evaluates the opportunities brought by IoHT and edge computing for a monitoring application. The general objective of this project is to demonstrate the potential of some emerging technology for the positive transformation of how healthcare services are provided to the seniors and to healthcare provider. According to its current development state, a proposed IoHT-based architecture of the monitoring application and a data analytics demo for a health parameter is presented.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"30 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":"130883217","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}

As the complexity of electrical power systems increase, the demands on the protective devices are also more challenging. A variety of communication schemes which complete the protection schemes have been developed and they are based on the exchange of logical data between the transmission line ends. This supplements the locally available data, confirming that a fault detected at one end in forward direction, is internal to the line, using the information from the other end/ends where protection had also detected a forward direction fault [1]. In this context, the aim of this article is to show the influence of digital communications for protection schemes on a proposed network area in the Romania power system. The studied transmission line is a short line therefore, according to [2] and [3], the protection scheme has both current differential protection as main protection and distance protection as back-up. Several fault scenarios were computed and tested in a platform that has designed the entire 400/220/110 kV transmission and distributions network of the Romanian power system is designed. The results conduct to proposed protection grading plan. Communication between the protection devices represent the basis for fault detection in the case of current differential protection or ensure fast tripping and selectivity requirements in distance protection.","PeriodicalId":352411,"journal":{"name":"2019 22nd International Conference on Control Systems and Computer Science (CSCS)","volume":"28 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":"126151407","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}
