Hidden Markov model technique for dynamic spectrum access
Dynamic spectrum access is a paradigm used to access the spectrum
dynamically. A hidden Markov model (HMM) is one in which you
observe a sequence of emissions, but do not know the sequence of states, the model went through to generate the…

Improving color rendering index of WLEDs with convex-dual-layer remote phosphor geometry using red-emitting CaGa2S4:Mn2+ phosphor
The white-light light-emitting diode (LED), a conventional illumination
solution, usually consists of one chip and one phosphor layer, which leads to the insufficient color rendering index (CRI) in this configuration. To optimize the efficiency of…

Integrated bio-search approaches with multi-objective algorithms for optimization and classification problem
Optimal selection of features is very difficult and crucial to achieve,
particularly for the task of classification. It is due to the traditional method of selecting features that function independently and generated the collection of irrelevant…

Modifying Hamming code and using the replication method to protect memory against triple soft errors
As technology scaling increases computer memory’s bit-cell density and
reduces the voltage of semiconductors, the number of soft errors due to
radiation induced single event upsets (SEU) and multi-bit upsets (MBU) also increases. To address this,…
