Distributed Delay Improves the Dynamics of Gene Regulation
… feature that governs the dynamics of GRNs is the delay between the start of transcription of a gene and the formation of a functional protein. Indeed, any model of Gene Regulation must account for this delay in some way in order to be useful. But the molecular mechanisms in a cell are subject to …

Spectral Solution Method for Distributed Delay Stochastic Differential Equations
Stochastic delay differential equations naturally arise in models of complex natural phenomena, yet continue to resist efforts to find analytical solutions to them: general solutions are limited to linear systems with additive noise and a single delayed term. In this work we solve the case of …

Enhancing Defect Coverage of VLSI Chips by Using Cost Effective Delay Fault Tests
We use circuit delay bounding based on a set of linear constraints, obtained from testing some paths in the circuit robustly, to investigate how well such tests cover distributed delay defects. Unfortunately, our experimental results using the above method show robust tests may not cover …

Stability Analysis and Stabilization of Linear Systems with Distributed Delays
… stabilization of linear systems with non-trivial distributed delays based on the application of the Liapunov-Krasovskii functional (LKF) approach. We first propose methods for designing a dissipative state feedback controller for linear distributed delay systems, where the delay is known and the …

Mathematical modeling and sparse identification of delay-driven dynamical systems with applications to gene regulatory networks
Delay-driven dynamics arise naturally in many biological and physical systems, where finite processing times, transport effects, and memory mechanisms significantly influence system behavior. Although such delays are often not directly observable, they play a critical role in determining stability, …

Analysis and implementation of robust numerical methods to solve mathematical models of HIV and Malaria co-infection
… firstly we focus on studying the effect of a distributed delay representing the incubation period for the malaria parasite in the mosquito vector to possibly reduce the initial transmission and prevalence of malaria. This model can be regarded as a generalization of SEI models (with a class …

Analysis and implementation of time-delay systems and networked control systems
Systems with delays frequently appear in engineering. The presence of delays makes system analysis and control design much more complicated. Networked control systems where the delays are often random are typical cases of such systems.<br/><br/>For one particular category of time-delays systems, …

Impact of Stochastic Transcriptional Delay on Gene Networks
… regulatory networks is to incorporate dynamical delay. The stochastic nature of the reactions necessary to produce protein leads to a waiting time that is randomly distributed, complicating simulation and analysis. We examine this problem using different examples and approaches. First, we …

High Quality Transition and Small Delay Fault ATPG
Path selection and generating tests for small delay faults is an important issue in the delay fault area. A novel technique for generating effective vectors for delay defects is the first issue that we have presented in the thesis. The test set achieves high path delay fault coverage to capture …

Stability Analysis of Time Delay Systems Using Spectral Element Method
… study the response and the stability of various delay differential equations (DDEs). The development of these new analysis techniques is motivated by the existence of delays in the governing equations of many physical systems such as turning and milling processes. </p><p>Delay differential …
