This paper describes a study towards user location system based on Kohonen Self-Organizing Maps (SOM) algorithm for locating user location with the existing Wi-Fi signals. With the novel use of Wi-Fi based on the IEEE 802.11 standards: inferring the location of a wireless client from signal quality measures, the Kohonen SOM paradigms were used. SOM

This study attempted to characterize seed fat from Madhuca longifolia known as Mee fat and its solid and liquid fractions with the objective of distinguishing them. A sample of Mee fat was partitioned into solid and liquid fractions using acetone as the solvent medium. The isolated fractions were compared to the native Mee fat sample with respect t

System analysis was conducted on a proposed combined system for methane steam reforming comprising conventional hydrogen production and waste heat recovery from steelmaking. Operating data for a conventional methane steam reforming system were collected and analyzed. The results showed that the conventional system utilized only 60% of the natural g

Context histories, especially when recorded over a long term, offer a wide range of possibilities to enhance the services provided by ubiquitous computing system application. These possibilities include inferring of current and past user location, and selection of devices. However, the prediction of future context based on the recorded past locatio

Nickel-iron nanocrystalline alloy films were prepared on copper substrates by electrochemical deposition at various current densities of 6, 9.7, 11.5 and 15.2 A dm-2. X-ray diffraction measurements confirmed that all nickel-iron alloy films formed have face-centered cubic structure. The structural parameters such as the lattice constant, crystallit

Nickel-iron-silicon nitride nanocomposite thin films were prepared by electrodeposition technique. The deposition was performed at current density of 11.5 A dm-2. Nano-size silicon nitride was mixed in the electrolyte bath as dispersed phase. The effects of silicon nitride nanoparticulates in the nickel-iron nanocomposite thin films were investigat

Palletier (2008) states that technology plays a big role in developing children’s writing. She claims that the computer is one of the significant forms of technology because of its easy accessibility. Franco (2008) also stresses the importance of ICT in enhancing children’s writing development. He examines the use of different teaching methods

Multidrug resistance Staphylococcus aureus (MRSA) is a major threat to health sector worldwide due to their prevalence, intrinsic virulence & limited therapeutic means. MRSA infections complicate therapy and could double the mortality rate amongst the immuno-compromised, the elderly, infants and patients at the surgical and burnt units. The cos

Cell-based regenerative therapies, based on in vitro propagation of stem cells, offer tremendous hope to many individuals suffering from degenerative diseases that were previously deemed untreatable. Due to the self-renewal capacity, multilineage potential, and immunosuppressive property, mesenchymal stem cells (MSCs) are considered as an attractiv

This paper is an attempt to survey the applications of computational intelligence techniques for predicting crude oil prices over a period of ten years. The purpose of this research is to provide an exhaustive overview of the existing literature which may assist prospective researchers. The reviewed literature covers a spectrum of publications on t
