The deterministic energy efficient protocol for adjustable sensing range (ADEEPS) is one of the important protocols for enhancing the lifetime of a wireless sensor network. This protocol however considers the underlying network of homogeneous nature. In this paper, we propose hetADEEPS (heterogeneous ADEEPS) protocol that considers the underlying network of heterogeneous nature. The heterogeneo...

We consider a specific kind of Abstract State Machines. It is shown how the machines can be used to provide a low-level formal semantics for a tiny object-oriented language, including control flow operators, object creation and field manipulation. Then the decidability result is established for checking invariants of programs corresponding to that class of ASMs.

Several attractive theories predict the existence of mirror fermions. There is a good theoretical reason to expect that the lightest mirror fermions might have relatively long lifetimes. We explore the experimental consequences of such a possibility, focusing on mirror lepton production at the SLC near the Z” resonance. We find that by going slightly off resonance or by polarizing the electron ...

Wireless Sensor Networks (WSNs) consists of widespread random deployment of energy constrained sensor nodes. Sensor nodes have different ability to sense and send sensed data to Base Station (BS) or Sink. Sensing as well as transmitting data towards sink requires large amount of energy. In WSNs, conserve energy & prolonging the lifetime of network are great challenges. Many routing protocols ha...

Recoil-free emission of 14.37 keV lines by iron atoms undergoing radioactive decay can be exploited in high-resolution Mössbauer spectroscopy thanks to the long lifetime of the excited state. This experiment determined the natural energy width of the Mössbauer 14.37 keV line to be (1.36 ± 0.24)· 10−12 keV, giving a relative width of around 10−13. Another application of this experiment was in ch...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

Wireless sensor networks (WSNs) are being envisioned for certain applications like habitat monitoring and environmental sensing. Wireless sensors are deployed to achieve network load balancing, prolonging network lifetime, and improving network coverage. To achieve these goals, energy estimation is one of the main constraints and concerns to consider, while deploying wireless sensors in a WSN f...

The expression for the ( + ) atom lifetime is derived within the Bethe-Salpeter approach. First-order perturbative corrections due to the contribution of strong interactions are taken into account. It is demonstrated that the atom lifetime can be expressed in terms of the solutions of the Coulombic problem (the wave function of the 1S state at the origin 1(0), the binding energy of the S-state ...
