Coarse-grain reconfigurable architectures, like the Montium TP, have proven to be a very successful approach for low-power and high-performance computation of regular digital signal processing algorithms. This paper presents the implementation of a class of non-power-of-two FFTs to discover the limitations and Flexibility of the Montium TP for less regular algorithms. A non-powerof-two FFT is l...
detecting faces in cluttered backgrounds and real world has remained as an unsolved problem yet. in this paper, by using composition of some kind of independent features and one of the most common appearance based approaches, and multilayered perceptron (mlp) neural networks, not only some questions have been answered, but also the designed system achieved better performance rather than the pre...
In several digital signal processing algorithms, intermediate results between computational stages are reordered according to stride permutations. If such algorithms are computed in parallel with reduced number of processing elements where one element computes several computational nodes, the permutation, instead of being hardwired, requires a storage of intermediate data elements. In this pape...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Multiwavelets are a new addition to the body of wavelet theory. Realizable as matrix-valued filterbanks leading to wavelet bases, multiwavelets offer simultaneous orthogonality, symmetry, and short support, which is not possible with scalar two-channel wavelet systems. After reviewing this theory, we examine the use of multiwavelets in a filterbank setting for discrete-time signal and image pro...
climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...
this study was undertaken to investigate the effect of socioeconomic factors on fish catch around the lower ogun river in isheri-olofin area (downstream) and ishasi (upstream). two hundred and fifty (250) respondents were randomly sampled. the data was analyzed using descriptive statistics and chisquare. it was found that a large percentage (74.4%) owned personal fishing craft.18% of the respon...
purpose: vision disorders are closely associated with poverty, particularly blindness. we determined the prevalence of low vision and blindness in different socioeconomic levels. our goal was determination of correlation between socioeconomic determinants and visual acuity in varamin city. methods: this community based study was done on 2737 people over the age of 50 years, living varamin city ...
