The parameters of the control are designed for ensuring local asymptotic stability for a given range of the impedance. Furthermore, the control includes a strategy of active power curtailment in order to avoid the injection of a large amount of reactive power to the grid. Numerical simulations confirm the expected voltage regulation and the control robustness with respect to the grid impedance variations without the requirement of any estimation or measure of the actual impedance.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89788225","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}

Hidden state transitions, state dependent keys, and temporal based transitions are implemented as a means to combat probing style attacks, such as the SAT attack. SPICE simulations are performed on modified state machines to characterize the overhead of implementing the three techniques in a circuit. Implementing temporal based transitions increases the area of the circuit by 68.42%, the power by 43.17%, and did not impact circuit delay. However, increasing the circuit size significantly reduces the overhead of state space encryption. For example, encrypting two registers in the s15850 ISCAS89 benchmark circuit resulted in an area overhead of 0.026%, presenting a low overhead means of securing sequential logic.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"11 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89487117","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 switching mechanism is not known in all details yet, accurate device modeling is quite challenging. Here, we introduce six evaluation criteria for modeling filamentary switching devices based on the valence change mechanism, which is a subclass of redox-based memristive devices. The criteria include the plausibility of the simulated I-V and I-t characteristics, the nonlinearity of the switching kinetics, the feasibility of predicting complementary resistive switching correctly, the possibility of programming different resistance states, the state-dependence of the resistive switching, and the occurrence of a fading memory behavior. Four different models that have been proposed in literature are analyzed with respect to these criteria. These models are Kvatinsky's VTEAM model, the Stanford RRAM model, Strachan's TaOx memristor model and a nonlinear physics-based model proposed by our group.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"34 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77506233","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}

Supernode is a set of geographically closely associated nodes. Using the supernode graph structure, the bus transport and the metro transport network structures are analyzed by treating them as independent mono-layer or multi-layer network structures. A method of spatial amalgamation is proposed to integrate the two transport layers. A set of most influential nodes in the network is identified by assigning node weight to each node with respect to both mono-layer and multi-layer analysis. The behavior of these influential nodes is better characterized by categorizing them as either emitter, absorber or neutral zones.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"3 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86979754","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 global OFE requires a large number of external memory accesses (EMAs) and matrix computations, thus it is incompatible on mobile devices with real-time constraints. For real-time OFE on mobile devices, this paper proposes two key features, both of which to reduce the required memory bandwidth and a number of computations: 1) Tile-based hierarchical OFE enables intermediate data to be processed within 328 KB on-chip memory without external memory access. 2) Background skipping eliminates redundant matrix computation for zero optical flow region. Therefore, the proposed features reduce external memory bandwidth and computation by 99.7 % and 50.7 %, respectively. The proposed 4 mm2 OFE processor is implemented in 65 nm CMOS technology, and it achieves real-time OFE of 46.1 frames-per-second (fps) throughput for an image resolution of QVGA (320×240) and the resulting optical flow can be successfully used for action recognition.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"30 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87188824","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}
