The first circuit is a single phase bridge with pure resistive load. This circuit is linear one, with sinusoidal input and non-sinusoidal output. The main power theories allow obtaining the correct results. The second circuit is a simple series diode resistance connection. This circuit is one with nonlinear input (sinusoidal voltage and non-sinusoidal current) and linear non-sinusoidal output. The main power theories do not allow obtaining the correct results of apparent power calculation. The conclusion drawn is that the main power theories allow obtaining the correct results of active power calculations of linear and non-linear circuits.

In the encryption, encryption standards such as DES algorithm and AES algorithm are widely used and are theoretically secured. However, when these encryption standards are incorporated into electronic devices, it is reported to be possible to estimate the confidential information by analyzing the secondary information such as power consumption during the circuit's operation. The transformed masking method is a typical measure against this attack at the algorithm level. In this method, adding random numbers to intermediate data of encryption masks the correlation between power consumption and confidential information. The transformed masking method is effective for hamming weight attack that focuses on the bit value. This study clarifies random numbers used in the transformed masking method that are effective for this attack. Experimental results show the validity of the proposed method.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131351674","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 describe a novel system engineering technique that helps alleviate the problem by allowing many such decisions to be delayed until they can be made with sufficient supporting information. We expect this approach will substantially improve the effectiveness of software design in the most difficult cases of complex software systems embedded in dynamic and uncertain environments. We describe the steps in the process, and how the Problem Posing Interpretation extends the Scenario Based Engineering Process to provide this flexibility.

The design of UAS swarms demands close attention to the system-wide qualities such as reliability, availability, performance, and adaptability. Software architecture of a system has shown to play an important role in the realization of these qualities. In this paper, three important control architectures for UAS swarms systems are evaluated according to the system-wide quality attributes such as reliability, availability, performance, and adaptability. The digital pheromone control architecture is selected as an optimal solution satisfying the above criteria. More specifically, the three-tier architectural style provides a context in which quality attributes such as reliability, availability, performance, and adaptability are realized. The proposed three-tier software architecture is then specified in the Darwin architecture description language.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123355209","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}

A Dynamic System Matching Technique for Improving the Accuracy of Subsystems 一种提高子系统精度的动态系统匹配技术

Stubberud","doi":"10.1109/ICSEng.2011.33","DOIUrl":"https://doi.org/10.1109/ICSEng.2011.33","url":null,"abstract":"Many complex systems can be described as a combination of subsystems, that is, the elements of the complex system are themselves systems. A subsystem design is often modelled by a differential equation with several coefficients rather than as a constant, as a resistor is modelled, or as a single parameter equation, as a capacitor is modelled. Manufacturing errors produce subsystems whose coefficients vary from the desired coefficients of subsystem design. The coefficient variations contribute to modelling errors in the subsystem, and thus to modelling errors in the complex system. As is the case of elements in an electronic circuit, one way of controlling the variability of a manufactured subsystem is to impose tight control on the manufacturing process so that the component values are within some specified, acceptable bounds. This can be expensive and, in some applications, it may be impossible to achieve acceptable bounds. In a recent paper, [2], the authors presented a method for combining the measurements from many MEMS gyroscopes using a technique based on the concept of dynamic element matching. This was shown to effectively control the modelling errors when the outputs of the many micro-gyroscopes are corrupted by manufacturing errors. This technique essentially transforms the effects of the many manufacturing errors into an additive white noise in the subsystem output. The effect of the additive white noise can be effectively decreased by applying a filter, e.g., a Kalman filter, to the output signal. In this paper, this technique is generalized to applying the concept of dynamic element matching to complex subsystems which may be 'elements' in more complex systems. Because the method deals with systems rather than elements, it will be called dynamic system matching.","PeriodicalId":387483,"journal":{"name":"2011 21st International Conference on Systems Engineering","volume":"21 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120899440","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}
