Control can enable high-bandwidth nanopositioning needed to increase the operating speed of scanning probe microscopes (SPMs). High-speed SPMs can substantially impact the throughput of a wide range of emerging nanosciences and nanotechnologies. In particular, inversion-based control can find the feedforward input needed to account for the positioning dynamics and, thus, achieve the required pr...

Matrix inversion algorithm acting an important role in MIMO wireless communication.In this paper, we presenta matrix inversion algorithm and it’s applications in the high speed MIMO LTE receiver which is based on floating point DSP. Matrix operations are the most costly computational module within MIMO receivers but a matrix inversion algorithm is very easy to compute and significantly reduce t...

Experimental data often can only be interpreted by means of a computational simulation that approximately models the physical situation. We will discuss techniques that facilitate application to complex, large-scale simulations of the standard approach to inversion in which gradient-based optimization is used to nd the parameters that best match the data. The fundamental enabling techniques are...

class Actor extends Thread { private var mailbox: List[Any] def !(msg: Any) = ... def receive[a](f: PartialFunction[Any, a]): a = ... ... } The ! method is used to send a message to an actor. The send syntax a!m is simply an abbreviation of the method call a.!(m), just like x+y in Scala is an abbreviation for x.+(y). The method does two things. First, it enqueues the message argument in the act...

air pollution is one of the most important problems in urban areas that always threaten citizen's health. photochemical smog is one of the main factors of air pollution in large cities like tehran. usually smog is not only a part of nature, but is being analyzed as an independent matter, which highly affects on the nature. it has been used as relationship between atmospheric elements such as te...

By analysing potential field data in the wavelet domain and performing a multi scale edge detection we can automate what is commonly called 'worm analysis', i.e., the traditional visual inspection of gravity and aeromagnetic data in order to detect shallow faults, lineaments, contacts etc. More importantly, with the use of an appropriate wavelet, defined by the physics of the problem, informati...

In this paper, we generalize a recently introduced expectation maximization (EM) method for graphs and apply it to content-based networks. The EM method provides a classification of the nodes of a graph, and allows one to infer relations between the different classes. Content-based networks are ideal models for graphs displaying any kind of community and/or multipartite structure. We show both ...

We propose a novel efficient cryptanalytic technique allowing an adversary to recover an initial state of filter generator given its output sequence. The technique is applicable to filter generators possessing local affinity property.
