The dynamics of the space vehicle is expressed by using the equations describing the dynamics of the three celestial bodies (satellite, Earth, and Moon). For the design of the stabilization control law, a Lyapunov function is considered; it depends on the deviation of the satellite’s position and velocity vectors with respect to Earth relative to the vectors associated to the satellite’s reference orbit. From the condition of automatic control system’s absolute stability, one assures the simultaneous convergence to zero of the deviations associated to the position and velocity vectors with respect to the vectors describing the satellite’s reference orbit. The theoretical results are validated in Matlab/Simulink environment and the dynamic characteristics associated to the new control system are obtained.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115025804","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}

However, established development processes are component-oriented. As GAUSEMEIER puts it, a shift towards development processes and methods that focus on product functions is necessary in order to strengthen customer-orientation, so called function-oriented product development. In addition, observations in development practice have shown that products are not developed on a white sheet of paper, but rather through the systematic variation of technical subsystems over generations, as described in the model of PGE – Product Generation Development by ALBERS. But how can function-orientation in product development be supported based on the model of PGE – Product Generation Engineering? In this contribution, an empirical study is carried out in order to identify major challenges of Systems Engineering in the age of Digitalization. According to the experts, consequently focusing on product functions throughout the development process is a promising way to successfully meet those challenges. Considering the practical needs of the experts of Systems Engineering, the model of PGE – Product Generation Engineering is advanced by engineering generations that support structuring the development process of a product generation and support function-orientation. An engineering generation states the intended customer, user and provider benefit of a product generation in development and supports harmonizing solution-open product attributes and functions with the solution-specific development of technical subsystems. This enables customer-orientation in the development of complex mechatronic products. Furthermore, engineering generations are exemplary applied in the complete vehicle development of a German OEM. Based on the understanding of engineering generations discussed in this contribution, processes and methods can be developed in the context of the model of PGE – Product Generation Engineering to support function-orientation throughout the development process. In particular by defining and validating engineering generations from a customer and user point of view and modeling the dependencies between product attributes and technical subsystems based on product functions.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114412124","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}

Its causes are unknown but many theories detail that it occurs during the gestation period when the fetus has not enough oxygen in the brain (hypoxia). This paper shows the last investigative stage in the development of transmitters of needs, here is detailed the third version of it, which is based on completely improving its predecessorsin order to cover a larger population of boys and girls with cerebral palsy that present clinical pictures of hemiplegia and quadriplegia. Children who suffer this disorder cannot communicate their needs, thoughts or desires even with language of gestures, because it is difficult for them to learn it and in many cases their bodies do not even allow them to move their arms. So it is necessary to find a way to provide these children with a means of communication, a non-invasive method, that is; a system that adapts its functionality to the specific needs of children. This latest version of the device brings an update of the mobile application. This is necessary for the child's interaction with their parents, teachers or therapists. The validation method of the device is the contrast of the results obtained with respect to its predecessor version. All these points including the process of development of said system, is detailed in the chapters below.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"75 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113989012","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}

Naik, Paul Jenkins","doi":"10.1109/SYSENG.2018.8544408","DOIUrl":"https://doi.org/10.1109/SYSENG.2018.8544408","url":null,"abstract":"Cybersecurity is becoming increasingly challenging due to escalating security attacks on networks. A honeypot system is an effective entrapment mechanism for collecting information about these attacks and attackers. Nonetheless, one of the biggest risks to the honeypot system is the possibility of being fingerprinted by an attacker. As a consequence of the fingerprinting, the identity of the honeypot system could be revealed or it could be transformed into a bot to attack others. Several efficacious methods are proposed to fingerprint the honeypot system or to prevent it. However, there is no method available that can identify and predict fingerprinting in real-time, to save the honeypot system. Therefore, this paper proposes a technique to identify and predict fingerprinting attacks on the honeypot system in real-time. This technique is based on the fingerprinting process which necessitates a series of events by the attacker and by analysing these events contemporaneously, it is feasible to identify and predict the fingerprinting attack on the honeypot system. For the development of this technique, a popular honeypot tool KFSensor and fingerprinting tools Nmap and Xprobe2 are utilised to collect fingerprint data relating to the honeypot system. This data is analysed to detect the various attack techniques used by popular fingerprinting tools to propose a solution.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131638758","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}
