If Aq (β, α, k) is the scattering amplitude, corresponding to a potential q ∈ L2(D), where D ⊂ R3 is a bounded domain, and eikα·x is the incident plane wave, then we call the radiation pattern the function A(β) := Aq (β, α, k), where the unit vector α, the incident direction, is fixed, β is the unit vector in the direction of the scattered wave, and k > 0, the wavenumber, is fixed. It is shown ...

This paper explores technical and aesthetic possibilities for the convergence of smart materials and computation. It describes Pulp-Based Computing, Sprout I/O and Shutters, with particularly emphasis on how craft, collocated input/output and material intelligence can provide the framework for extending computation and interactivity into our everyday objects and spaces. By leveraging the dynami...

Nanoparticle technologies intended for human administration must be designed to interact with, and ideally leverage, a living host environment. Here, we describe smart nanosystems classified in two categories: (i) those that sense the host environment and respond and (ii) those that first prime the host environment to interact with engineered nanoparticles. Smart nanosystems have the potential ...

Future missions to the planets and moons in our Solar System may require new technology. Missions with surface or atmospheric mobility or sample acquisition requirements will need advanced actuation technology to operate in the extreme environments found in the Solar System. Depending on the specific mission this technology may be required to withstand 10’s of Kelvin environments or temperature...

the present study evaluates effects of organizational culture on organizational commitment with emphasis on the role of mediator entrepreneurial orientation departments within the material procurement management at national iranian south oil company. statistic population included of 470 experts and managers, 23 departments within the material procurement management that using stratified random ...

Smart phones are being increasingly used among health professionals. Ophthalmological applications are widely available and can turn smart phones into sophisticated medical devices. Smart phones can be useful instruments for the practice of evidence-based medicine, professional education, mobile clinical communication, patient education, disease self-management, remote patient monitoring or as ...

The main objective of this article is to present the semi-active vibration control using an electro-rheological fluid embedded sandwich structure for a cantilever beam. ER fluid is a smart material, which cause the suspended particles polarize and connect each other to form chain. The stiffness and damping coefficients of the ER fluid can be changed in 10 micro seconds; therefore, ERF is suitab...

This work presents a cyber-physical drilling machine that incorporates technologies discovered in the fourth industrial revolution. The is designed to realize its state by detecting whether it hits or breaks through workpiece, without need for additional sensors apart from position sensor. Such self-recognition enables adapt and shift controllers handle position, velocity, force, based on workp...
