ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Video data compression using artificial neural network differential vector quantization [PDF]
An artificial neural network vector quantizer is developed for use in data compression applications such as Digital Video. Differential Vector Quantization is used to preserve edge features, and a new adaptive algorithm, known as Frequency-Sensitive ...

Acknowledging the potential role of animal self-medication [PDF]
This report was presented at the UK Organic Research 2002 Conference. Much research on animal health and welfare assumes that animals passively endure the pathogens, diet, and environmental conditions that come their way.

ABSTRACT Flooding is one of the most devastating natural disasters worldwide. It is also expected to become more severe as climate change impacts are realised. Two‐dimensional (2D) hydrodynamic models are used to obtain reliable inundation estimations.

Abstract Urbanization can enhance local precipitation through thermodynamic and dynamic effects, yet detection of the urban rainfall island (URI) effect remains uncertain at the global scale because results vary across data sets, methods, and spatiotemporal resolutions.

Abstract Spaceborne radar systems such as the Global Precipitation Measurement Mission (GPM)'s core satellite Dual‐frequency Precipitation Radar (DPR) provide global insight into precipitation structure, storm morphology, and hydrological cycles. However, their limited spatial and temporal sampling and high cost constrain their ability to continuously ...

ABSTRACT Farm diversification provides alternative sources of income and helps mitigate risks associated with relying solely on one crop. This study investigated the impact of diversification on the welfare of Ghanaian cocoa farmers. Primary data were collected from 403 smallholder cocoa farmers using a multi‐stage sampling technique and analyzed using

The Untapped Hydropower Potential of World's Cities
Abstract Many large cities around the world experience frequent power outages and yet have an abundance of tall buildings and experience rainfall. This represents a unique and scalable opportunity for cities to capture the intermittent rainwater at high elevation and convert the potential energy into electricity for rechargeable batteries at street ...

On the optimality of code options for a universal noiseless coder [PDF]
A universal noiseless coding structure was developed that provides efficient performance over an extremely broad range of source entropy. This is accomplished by adaptively selecting the best of several easily implemented variable length coding ...

Pemampatan Citra Keabuan dengan Algoritma Adaptive Huffman dan LZW
Perkembangan data digital cukuplah pesat, mulai dari ukuran hingga jenis berkas. Untuk mengimbangi hal tersebut maka perlu ada-nya algoritma pemampatan guna mengurangi ukuran penggunaan media penyimpanan. Salah satu algoritma yang cukup lama ada adalah Adaptive Huffman, dan serta mengkombinasikannya dengan LZW, maka hasil pemampatan yang didapat akan ...
