Analysis of Acyclic Attenuating Systems for the SSR Protection Model
1985 IEEE Symposium on Security and Privacy, 1985The distribution of privileges in domains of subjects defines the protection state of a system. Operations which change this state are themselves authorized by privileges in the current state. This poses an analysis problem of characterizing states which are derivable from a given initial state.

METALLURGICAL ANALYSIS FROM SARAZM, TADJIKISTAN SSR
Archaeometry, 1987Recent excavations of the Bronze Age site of Sarazm (35W2000 B.C., uncalibrated) were undertaken by a collaborative team of archaeologists from the U.S.S.R. and U.S.A. The site is located in the Zeraoshan Valley in Tadjikistan SSR. A series of radiocarbon dates are presented as well as the analysis of 8 metallurgical samples.

Synthesis of power system model for SSR analysis
TENCON 2010 - 2010 IEEE Region 10 Conference, 2010In this paper, the systematic synthesis of network model from a power system database for subsynchronous resonance (SSR) analysis in large power systems is discussed. The model is convenient to incorporate in a computer program using MATLAB sparse-matrix function.

Analysis of Thyristor-Controlled Shunt SSR Countermeasures
IEEE Transactions on Power Apparatus and Systems, 1985This paper presents the results of a study to compare the effectiveness of three SSR countermeasures. Both frequency and time domain techniques were used to insure the integrity of the investigation. Reactive power modulation with generator speed feedback will damp all SSR modes if phase lags associated with thyristor firing controls are compensated ...

Analysis of SSR signals by super resolution algorithms
Proceedings of the Fourth IEEE International Symposium on Signal Processing and Information Technology, 2004., 2005A new method for SSR (secondary surveillance radar) signal analysis, in particular SSR Mode S replies, can be obtained exploiting the super resolution algorithms capability to discriminate signals in the frequency domain. This work summarises the results obtained by the application of Tufts-Kumaresan, Music, Esprit and Unitary Esprit algorithms to ...

Analysis of SSR with Fixed Series Compensation
1999It was mentioned in chapter 1 that series compensated transmission lines connected to turbogenerators can result in Subsynchronous Resonance (SSR) in which both Induction Generator Effect (IGE) and Torsional Interaction (TI) can occur. In this chapter, the analysis of SSR with fixed series compensation is presented. Both frequency domain and eigenvalue

Dynamic modeling of a TCSC with application to SSR analysis
IEEE Transactions on Power Systems, 1997Conventional subsynchronous resonance (SSR) study methods such as eigenanalysis require a linear dynamic model of each device. FACTS devices such as thyristor-controlled series capacitors (TCSC) are difficult to model due to their nonlinear switching behaviour.
