One of the current trends in computer science leads to the design of computing organizations based on the activity of a multitude of tiny cheap decentralized computing entities. Whether these chips are integrated into paintings or disseminated in open environments like dust, the fundamental problem lies in their cooperative operation so that global functions are obtained collectively. In this p...

Decentralized Object Location and Routing: A New Networking Paradigm

At present, a series of challenges are impeding large-scale application high temperature radar absorbing coatings (RACs), such as complex preparation raw material and complicated technology processing. In this paper, we designed experimentally demonstrated high-temperature metamaterial RAC (MRAC) with strong absorption thin thickness, which is composite coating layer metamaterial. To avoid mate...

Nowadays, the presence of robotics in human-oriented applications demands control paradigms to face partly known, unstructured and time-varying environments. Contact tasks and compliant motion strategies cannot be neglected in this scenario, enabling safe, rewarding and pleasant interactions. Force control, in its various forms, requires special attention, since the task constraints can change ...

Now a days DC drives are being used in versatile variable speed applications in industries. A separately excited DC motor is taken as a plant. The dynamic behaviour of a DC motor varies with the moment of inertia, friction of the load, temperature etc. which are evident from the applications such as rolling mills, wiring machines and tracking telescope. Non-linearities cannot be neglected when ...

in this paper, the competition between two supply chains and their elements is studied. each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...

We formally verify a direct model-reference adaptive control (MRAC) method that is used to enable flight control in adverse conditions. We use the bounded verification approach and verify the system by introducing templates for both the assumptions and the guarantees, and using QEPCAD to solve the resulting ∃∀ formula.

-Using Generalized Harmonic Analysis, a complete description of parameter convergence in Model Reference Adaptive Control (MRAC) is given in terms of the spectrum of the exogenous reference input signal. Roughly speaking, if the reference signal "contains enough frequencies" then the parameter vector converges to its correct value. If not, it converges to an easily characterizable subspace in p...

UNLABELLED PET/MRI is an emerging dual-modality imaging technology that requires new approaches to PET attenuation correction (AC). We assessed 2 algorithms for whole-body MRI-based AC (MRAC): a basic MR image segmentation algorithm and a method based on atlas registration and pattern recognition (AT&PR). METHODS Eleven patients each underwent a whole-body PET/CT study and a separate multibed...
