The co-variation degree between individuals in their physiological signals can reveal insights about the quality of their interaction as well as their personal characteristics. In an effort to capture the amount of synchrony between Electrodermal Activity (EDA) streams occurring in parallel during dyadic interactions, we propose Sparse EDA Synchrony Measure (SESM), an index derived from the joint...
Silicon based Physical Unclonable Functions (PUFs) are circuits which measure random variations of the manufacturing process to generate a secret. The quality of a PUF predominantly depends on its predictability and reliability. Available quality measures are not always sufficient and do not show the root cause for high predictability. This paper suggests entropy and joint entropy of certain views...
Due to changes in the electric power system, small, distributed units substitute conventional power plants with regard to energy supply. This also holds for the provision of ancillary services. To this end, agents that represent units form coalitions. In this paper, a method is introduced to assess such coalitions with respect of how reliable they can provide ancillary services taking into account...
Optimal route selection with reliable expected travel time has been a focus of research in transportation networks where the reliability is subject to many uncertainty factors such as traffic incidents or recurring traffic congestions. In this paper we develop an approximation method to obtain the reliability of a route travel time in a stochastic time-dependent traffic network. The proposed method...
A reliability and reliability-based sensitivity analysis on mechanical parts with multiple failure modes is carried out in the proposed paper. Due to the unknown distributions of random variables, the first order second moment method are utilized to calculate the reliability of each failure mode. According to the characteristic that only a few failure modes occur when the parts fail, only the first...
Lifetime (long-term) reliability has been a main design challenge as technology scaling continues. Time-dependent dielectric breakdown (TDDB), negative bias temperature instability (NBTI), and electromigration (EM) are some of the critical failure mechanisms affecting lifetime reliability. Due to the correlation between different failure mechanisms and their significant dependence on the operating...
Correlated component failures (CCF) degrade system reliability, and hence, these failures must be explicitly incorporated into the reliability analysis process. Several contemporary efforts consider CCF, however, most of these approaches introduce an exponential number of parameters and are computationally intensive because they require a complete characterization of the joint distribution of the...
Due to the unreliability of road network caused by the traffic supply-demand contradiction and ATIS, the traffic flows between road sections or paths are correlated, as well as the corresponding travel time. Copula as a new method with its unique advantage in describing the correlations between variables is introduced into researching the travel time reliability in this paper.
Making analysis on the theories of D-S evidential reasoning, rough sets and extenics sets, the three theory held comparability in defining uncertainty sets. It's feasible to introduce the relevant theories and methods of extenics to information fusion and a method of extenics fusion (MEF) is presented as well. The method combines extenic correlation function with Dempster rule and is considered to...
The three-dimensional models of void beneath old cement slab corner with joint are set up using finite element ANSYS software. Through simulating Falling Weight Deflectometer testing, the influence on deflection is analyzed by factors, such as void depth, void area, load transfer capacity, cement slab thickness and temperature, and fitted the relationship between various factors and deflection. It...
Process systems are different from discrete manufacturing systems in that they are composed of many interlocking subsystems that consist of various tightly coupled units. Hence, whenever a small unit of a subsystem functions badly, it could influence or cause the whole system to function abnormally. Under this circumstance, how to locate abnormal or failed units will be a very formidable task. By...
This paper presents a study of the resistance of solder joints to failure when subjected to strain rates that simulate the conditions of drop impact on a portable electronic product. Two test methods are used in this study: board-level drop/shock test (BLDT) and component-level ball impact test (BIT). The performance of 12 material combinations consisting of 6 solder alloys and 2 pad finishes were...
This paper presents an efficient methodology to evaluate the economical limitations as well as the marginal impact of the solar thermal power system (STPS) on the utility system reliability and operating cost. The economic limitation is formulated by evaluating the annual expected fuel cost saving due to the inclusion of the STPS and considering the installation cost of the STPS as well as the necessary...
