Abstract: There is continuous intensive research on image compression techniques in wireless sensor networks (WSNs) in the literature. Some of the image compression techniques in WSNs that exist in the literature include discrete cosine transform (DCT), discrete waveform transforms (DWT), set partitioning in a hierarchical tree (SPIHT), and embedded zero tree wavelet (EZW) coding. Research on image compression in WSNs is necessitated by the need to improve the energy efficiency of sensor nod...
Aim: To document the ethnobotanical uses in Taktse Chiwog (Village blocks) by local healers Study Design: Semi-structured interview and direct interview was conducted with the prior approval from the Chiwog official. Two local healers/informants were contacted for interview before field visits based on their popularity and experience of using medicinal plants in their locality. Place and Duration of Study: The study was conducted at Taktse Chiwog, Trongsa Dzongkhag, Bhutan between July and O...
The environmental audit of the Tunu/Kanbo area of Niger Delta, Nigeria was carried out to assess the impact of logging and timber exploitation in the area. The audit showed a high loss of endangered, threatened and economic forest species in the area; e.g Terminalia superba. The unlawful logging and “forest abuse” common in the area is detrimental to conservation of biodiversity attempts and ideals. It is recommended that regeneration efforts be put in place and intensified so as to esche...
Comparative studies on the pedological characteristics, morphological traits and productivity indices of three species of the genus Ipomoea was done in Uyo metropolis, Akwa Ibom State, Nigeria. Morphological parameters (leaf length, leaf width and leaf area index) and productivity indices (chlorophyll a, b carotenoids and Chlorophyll Concentration Index (CCI)) of these species were determined using standard methods. The results showed that amongst the three species studied Ipomoea mauritiana ...
