This paper introduces the concepts of Dwell-Time invariance (DT-invariance) and maximal constraint admissible DT-invariant set for discrete-time switching systems under dwell-time switching. Main contributions of this paper include a characterization for DT-invariance; a numerical computation of the maximal CADT-invariant set; an algorithm for the(More)
Micro-injection of zebrafish embryo is widely applied in biology for the analysis of early developmental processes. The success of a micro-injection to a large extent depends on the mechanical interaction between the micro-pipette and the membrane of the zebrafish embryo. In this paper, we present the development of (i) a maximum stress model of the(More)
The microinjection is a common technique in genetic engineering for transferring genetic material into a cell. It is normally performed on a micromanipulation system that usually consists of an inverted microscope, a micromanipulator, a micropipette and an injector. Manual microinjection is a conventional and widespread practice. However, this approach(More)
We consider the problem of estimating the focal length of a camera from two views while the focal length is not varied during the motion of the camera. An approach based on Kru-ppaÕs equations is proposed. Specifically, we derive two linear and one quadratic equations to solve the problem. Although the three equations are interdependent in general, each one(More)
The paper reports a new method for three-dimensional observation of the location of focused particle streams along both the depth and width of the channel cross-section in spiral inertial microfluidic systems. The results confirm that particles are focused near the top and bottom walls of the microchannel cross-section, revealing clear insights on the(More)
This paper presents an approach for controlling gene networks based on a Markov chain model, where the state of a gene network is represented as a probability distribution, while state transitions are considered to be probabilistic. An algorithm is proposed to determine a sequence of control actions that drives (without state feedback) the state of a given(More)
