Location information is crucial for many applications in wireless sensor networks. Many types of localization algorithms have been proposed in the literature. Off-shelf sensors equipped with no specialized hardware are inexpensive and have made range-free localization schemes the most practical, especially in a large-scale sensor network. However, the range-free schemes have seldom considered t...

We derive the precise limit of SHS in the high activation energy scaling suggested by B.J. Matkowksy-G.I. Sivashinsky in 1978 and by A. Bayliss-B.J. Matkowksy-A.P. Aldushin in 2002. In the time-increasing case the limit coincides with the Stefan problem for supercooled water with spatially inhomogeneous coefficients. In general it is a nonlinear forward-backward parabolic equation with disconti...

One way to suppress flavor changing neutral currents or CP violating processes in supersymmetry is to make at least some of the first two generations’ scalars superheavy (above ∼ 20TeV). We summarize the motivations and challenges, theoretically and phenomenologically, for superheavy supersymmetry. We then argue for more viable alternatives on the superheavy theme and are led to models where th...

With a significant advance in ciphertext searchability, Public-key encryption with keyword search (PEKS) is the first keyword searchable encryption scheme based on the probabilistic encryption, such that it is more secure than almost all previous schemes. However, there is an open problem in PEKS that its search complexity is linear with the sum of ciphertexts, such that it is inefficient for a...

Demand response resources (DRRs) are usually aggregated in order to participate in wholesale electricity markets (e.g., capacity, energy, and ancillary service markets). In such DRR aggregation systems, uncertainty arising from, e.g., random failures, is unavoidable; this paper focuses on assessing the impact of such uncertain phenomena on the reliability of DRR aggregation systems. To this end...

Two different approaches are described for the creation of supramolecular systems potentially capable of recognition and catalysis. Using the design approach, we have been able to accelerate and influence two different Diels–Alder reactions within the cavities of porphyrin dimers and trimers; this is templating from the outside inwards. The selection approach is a synthetic chemical attempt to ...

Given that oral consonants often block total vowel assimilation (Aoki 1968, Steriade 1987), this case of metathesis can be analyzed as serving to allow assimilation to apply unimpeded (cf. Broselow 2001). In terms of Optimality Theory, both the constraint driving assimilation and the constraint blocking assimilation across an oral consonant are satisfied, at the cost of violating faithfulness c...

The worldwide increase in demand for environmentally friendly energy has led to the intensification of work on synthesis H2-containing fuel. dry reforming methane become one most important avenues research since consumption two greenhouse gases reduces rate global warming. A study NiAl composite materials as catalysts been carried out. Self-propagating high-temperature (SHS) used produce cataly...

In this work, intermetallic materials based on γ-TiAl in situ strengthened with the Ti3Al phase have been obtained from initial components of titanium and aluminum under conditions free SHS-compression one technological step ten seconds. This method combines process combustion mode self-propagating high-temperature synthesis (SHS) shear deformation synthesized materials. The following compositi...
