Background: Due to their size, microelectromechanical systems (MEMS) display performance indices affected by uncertainties linked to the mechanical properties and to the geometry of the films constituting their movable parts. Objective: In this perspective, a recently proposed multiscale and hybrid solution for uncertainty quantification is discussed. Methods: The proposed method is based on the (deep) learning Read More

Because of major developments in fundamental research and industrial applications, graphene's mass and low-cost production have become a vital step toward its real-world uses. Graphene, a one-atom-thick carbon crystal with a unique set of physical and chemical properties comprising extreme mechanical behaviour with excellent electrical and thermal conductivity, is emerging as a serious contender to replace many tr Read More

Background: Complete Ternary Adder is the prime building block for Ternary Carry Save Adder (TCSA) and acts as a critical deciding factor to optimize the overall speed-power performance for many complex ternary computing like ternary multiplications. Objective: This work proposes a new idea for high-speed complete Ternary Adder design with reduced Power-Delay-Product (PDP) using PTL (Pass Transistor Logic) base Read More

A transdermal patch is a topically applied adhesive patch that delivers a medication dose directly into the blood. The patch allows for the safe delivery of a drug to the targeted site, ideally by a permeable layer covering a reservoir of the drug by melting small patches of drug embedded in the adhesive, which is one benefit of transdermal drug delivery over most types of pharmaceutical deliveries, including oral, topical, intr Read More

Background: Correct modeling of squeeze-film damping (SFD) is an important consideration in the design of high-Q microresonators. In 2002, using the molecular dynamics (MD) approach, Bao et al. developed an analytical MD model for the evaluation of the SFD of a parallel-plate device in the free molecular regime. Their model was based on the energy exchange between the oscillating plate and gas molecules. Bao’s model is Read More

Background: As the technology node scales down to a deep sub-micron regime, the design of static random-access memory (SRAM) cell becomes a critical issue because of increased leakage current components. These leakage current components prevent the designing of a low-power processor as a large portion of the processor power is consumed by the memory part. Objective: In this paper, an SRAM cell is designed Read More

Background: The state estimation (SE) process in power systems estimates bus voltage magnitude and phase angles vital for operating the system securely and reliably. The power systems state estimation problem has been extensively solved through a weighted least squares (WLS) based static approach that fails to track the system dynamics. Furthermore, those approaches are not inherently robust against outliers, yieldi Read More

Background: Utilizing mirror movement precisely, one can undoubtedly make a diverse way for light. The movable mirror can be placed in the path of an optical tree net to perform different operations. Objective: In this paper, we have performed different logic, arithmetic, and one-bit data comparison operations using mechanical movable mirrors. Methods: Using two controls with three movable mirrors and two fixed mirro Read More

Background: Among the parameters that play an important role in describing the performance of many devices is carrier mobility which is a criterion for the easy movement in semiconductor crystals. Objective: The effect of carrier mobility on the performance characteristics of InGaN quantum well vertical-cavity surface-emitting laser was analytically investigated. Methods: By solving the Poisson’s equation, current den Read More
