Abstract:
This paper proposes a spatial multivariate CUSUM control chart in order to monitor the mean of a single characteristic of a product or process, when the measurements are taken in different locations on each sampled item. To estimate the variance and covariance matrix some tools from the geostatistics are used, taking into account the spatial correlation between the measurements. The performance of this control chart is explored by simulation and its use is illustrated with an example.

Abstract:
We are witnessing rapidly growing world dynamics caused by climate change, military, religious and ethnic conflicts, terrorism, refugee flows and weapons proliferation, political and industrial restructuring too. Dealing with frequently emerging crises may need rapid integration of scattered heterogeneous resources into capable operational forces pursuing goals which may not be known in advance. Proper understanding and managing of unpredictable and crisis situations may need their detailed simulation at runtime and even ahead of it.

Abstract:
A new method of analyzing distributed parameter control systems is presented, based upon their input/output representation in a spatially and temporally transformed frequency space. The classes of distributed systems amenable to the analysis are described in terms of their Green’s functions. The plants’ input/output relations are studied in the transformed space using the singular value decomposition to determine the system’s spatial performance. Performance is quantified in terms of generalized command following, disturbance rejection, noise rejection, controllability, and observability over

Full text
Abstract:
Microtubules are long linear polymers that switch randomly between periods of growth and shrinkage, in a process known as dynamic instability. In vivo, dynamic instability is regulated by microtubule associated proteins (MAPs). One class of MAPS, the kinesins, move actively along microtubules, and some regulate microtubule dynamics. Kinesin-8, a kinesin, regulates microtubule dynamics in a wide range of eukaryotic cells. Schizosaccharomyces pombe (S. pombe) provides a well-characterised system in which to study microtubule regulation by MAPs. During interphase, microtubules grow from the centr

Abstract:
Virtual camera control is nowadays an essential component in many computer graphics applications. Despite its importance, current approaches remain limited in their expressiveness, interactive nature and performances. Typically, elements of directorial style and genre cannot be easily modeled nor simulated due to the lack of simultaneous control in viewpoint computation, camera path planning and editing. Second, there is a lack in exploring the creative potential behind the coupling of a human with an intelligent system to assist users in the complex task of designing cinematographic sequences

Abstract:
The stabilization of a hip-actuated spatial double inverted pendulum can be considered as a problem of postural control of a humanoid robot. Based on an existing model of this underactuated mechanical system with four degrees of freedom, the ultimate objective is to design a suitable controller to achieve global stabilization around the unstable upright equilibrium position. This thesis presents a number of control algorithms and simulation results that provide either local stabilization or semi-global swing-up.

Abstract:
Iterative learning control (ILC) is a high performance method for systems operating in a repetitive manner, which aims to improve tracking performance by learning from previous trial information. In recent years research interest has focused on generalizing the task description in order to achieve greater performance and flexibility. In particular, researchers have addressed the ease of tracking only at a single, or a collection of time instants. However, there still remain substantial open problems, such as the choice of the time instants, the need for system constraint handling, and the abil

Multichannel arrays of phase modulators are attractive as fast, high resolution random-access beam deflectors and can find direct application to such areas as projection display and programmable optical interconnects.

Several forms of programmable DOEs for beam steering have been reported including a compact liquid crystal based system1 and faster electrooptic based devices.2-3 The electrooptic (E-O) systems permit much faster switching rates but at the cost of higher drive

Semiconductor photorefractive quantum well devices are prime candidates for high speed real-time image processing applications because of their high speed, small thickness and large electro-optic nonlinearities1,2,3.

Lateral spatial modulation of the field screening is translated to lateral spatial modulation of refractive index and absorption by the quantum confined Stark effect.

The western flower thrips (WFT), Frankliniella occidentalis (Pergande), is a serious widespread pest of vegetable and ornamental crops worldwide.
