Line balancing is an effective tool to improve the throughput of assembly line while reducing nonvalue-added activities, cycle time. LB is the problem of assigning operation to workstation along an assembly line, in such a way that assignment is optimal in some sense. This paper mainly focuses on improving overall efficiency of single model assembly line by reducing the non value added activiti...

We consider a model system of two coupled Hopfield neurons, which is described by delay differential equations taking into account the finite signal propagation and processing times. When the delay exceeds a critical value, a limit cycle emerges via a supercritical Hopf bifurcation. First, we calculate its frequency and trajectory perturbatively by applying the Poincaré-Lindstedt method. Then, ...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

The complex of cycles on a surface is a cell complex that encodes all the ways that an element of first homology can be written as an embedded cycle. It was introduced by Bestvina–Bux–Margalit and plays an important role in their calculation of the cohomological dimension of the Torelli group. We give a detailed proof that this complex is contractible, expanding upon one of the proofs given by ...

It is a fairly longstanding conjecture that if G is any finite group with IG/ > 2 and if X is any set of generators of G then the Cayley graph T(G : X) should have a Hamiltonian cycle. We present experimental results found by computer calculation that support the conjecture. It turns out that in the case where G is a finite quotient of the modular group the Hamiltonian cycles possess remarkable...

Combined automated NOE assignment and structure determination module (CANDID) is a new software for efficient NMR structure determination of proteins by automated assignment of the NOESY spectra. CANDID uses an iterative approach with multiple cycles of NOE cross-peak assignment and protein structure calculation using the fast DYANA torsion angle dynamics algorithm, so that the result from each...

The one-cycle current control is a non-linear technique based on the cycle-by-cycle calculation of ON time power converter switches. Its application not common in tracking fast-changing reference currents, due to necessity fast and accurate measurements, high-speed computing. In previous study, digital controller minimization integral error was developed applied three-phase shunt active filter....

This paper shows a tool chain of a set of ready-touse tools and libraries that enables the dynamic real-time simulation of vapour compression cycles. A new approach for calculation of fluid properties and numeric efficient component models are applied. As an Hardware in the Loop application a vapour compression cycle is exported to Scale -RT [5] using SimulationX [11] and connected to a hardwar...

This paper presents the design of a DC-AC power converter controller that bears the same benefits of a sliding mode controller but with the advantage of a fixedfrequency control signal. The controller is based on the imposition of zero averaged value of the sliding surface in each switching cycle. A keypoint of the presented controller is the calculation of the sliding surface’s derivative whic...
