Multimachine Stability01:25

Multimachine Stability

631
Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:

Radial System Protection01:23

Radial System Protection

488
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

Leaky Scanning02:28

Leaky Scanning

5.9K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Norton's Theorem01:14

Norton's Theorem

2.0K
Norton's theorem is a fundamental principle stating that a linear two-terminal circuit can be substituted with an equivalent circuit, which comprises a current source (ⅠN) in parallel with a resistor (RN). Here, ⅠN represents the short-circuit current flowing through the terminals, and RN stands for the input or equivalent resistance at the terminals when all independent sources are deactivated. This implies that the circuit illustrated in Figure (a) can be exchanged with the one...

Line Protection with Impedance Relays01:27

Line Protection with Impedance Relays

529
Coordinating time-delay overcurrent relays in complex radial systems and directional overcurrent relays in multi-source transmission loops can be challenging. Impedance relays address these issues by responding to the voltage-to-current ratio, specifically measuring the apparent impedance of a line. These relays become more sensitive during faults as current increases and voltage decreases, thereby reducing the apparent impedance.
Under normal conditions, low load currents keep the measured...

Censoring Survival Data01:09

Censoring Survival Data

688
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

Area of Science:

  • Computer Engineering
  • Cybersecurity
  • Integrated Circuit Design

Background:

  • Hardware Trojans pose increasing threats, particularly with fabless design and IP reuse.

  • To address the limitations of existing Trojan detection methods for untrusted IP modules.

Main Methods:

  • A novel approach to gradually build trust in suspected IP cores by comparing outputs from diverse untrusted implementations of the same IP.
  • Utilizing comparative analysis across multiple untrusted IP instances to identify malicious modifications.

Main Results:

  • The proposed method demonstrates a higher probability of Trojan detection compared to naive voting techniques.
  • Experimental results indicate reduced hardware overhead compared to simple voting while maintaining security levels.

Conclusions:

  • The developed methodology offers an effective solution for hardware Trojan detection in third-party IP cores.
  • The approach provides a practical and efficient alternative for securing integrated circuits against embedded threats.
