a novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. the nanocomposite was prepared using a domestic microwave oven. the prepared nanocomposites have been characterized by fourier transform infrared (ftir) spectroscopy, x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and uv- visible spectroscopy. the crystalline properties...

The compatibility between general relativity and the property that spacetimes are ebeddable manifolds is further examined. It is shown that the signature of the embedding space is uniquely determined provided the embedding space is real and its dimension is kept to the minimal. Signature changes produce complex embeddings which in turn may induce topological changes in the space-time. Space-tim...

The impact of an inhomogeneous arrangement of nodes in space on a network organization cannot be neglected in most real-world scale-free networks. Here we propose a model for a geographical network with nodes embedded in a fractal space in which we can tune the network heterogeneity by varying the strength of the spatial embedding. When the nodes in such networks have power-law distributed intr...

The finite field modular multiplier is the most critical component in the elliptic curve crypto processor (ECCP) consuming the maximum chip area and contributing the most to the device latency. Modular multiplication, point multiplication, point doubling are few of the critical activities to be carried out by multiplier in ECC algorithm, and should be managed without compromising on security an...

A novel mechanism inspired by spider legs is presented and discussed in this paper. The mechanism has the potential to be used in future space applications, although the harsh space conditions, and in particular outgassing, should be carefully addressed in the design of a space-qualified model, The mechanism, called “Smart Stick”, has one degree of freedom and is actuated by a pressurised fluid...

Rigidity in m-Space.

Matroid theory has many classical applications in combinatorics and geometry. Abstract rigidity matroids are generalizations of the infinitesi-mal rigidity matroids of frameworks in Euclidean space. In this paper we give a local characterization for abstract rigidity in any dimension. The conditions in this characterization are in many instances easier to verify than those in the definition of ...

A detailed derivation of $3+1$ dimensional induced or emergent gravity in the IKKT matrix model at one loop is given, as announced [1]. The mechanism requires a brane configuration with structure ${\cal M}^{3,1}\times {\cal K} \subset {\mathbb R}^{9,1}$, where M}^{3,1}$ noncommutative space-time brane, and K}$ are compact fuzzy extra dimensions embedded target space. 3+1-dimensional Einstein-Hi...

Design space exploration is an important factor in embedded systems design. During several steps in a state-of-the-art design flow, designers have to decide between many design alternatives. The decisions are located at various levels of abstraction. In addition, the choices affect several design goals, the alternatives therefore represent a multi-criteria decision problem. Further, the space o...
