The skyrocketing prices of oil and food are matters of great concerns for consumers, producers, national and international bodies. This book addresses this aspect in five independent but related essays. The first two essays model the extent of volatility of oil and food price shocks. Third essay examines the cross country mean and volatility spillo

Porous alumina containing hydrothermal derived hydroxyapatite (HA) composite were successfully fabricated via protein foaming-consolidation method. Alumina and HA powders were mixed with yolk, starch and darvan 821 A at an adjusted mass ratio to make slurry. The slurries were cast into cylindrical shaped molds and then dried for foaming and consoli

Handwritten digits classification has many useful applications. This has prompted decades of research into algorithms to produce an effective system of classifying handwritten images into text. Image processing and feature extraction play a large role in this process. An intelligent system is one, which is taught, and one, which uses this learning

The design and development of a pressure sensor based typing biometrics authentication system (BAS) is discussed in this paper. The dynamic keystroke, represented by its time duration and force generates a waveform, which when concatenated results in a user’s typing pattern for the typed password. The design of the BAS is in two stages, whereby t

Sapium baccatum is usually used as a timber. Its medicinal values are not well known and very little research has been conducted concerning the plant. Consequently, this study was conducted to observe toxicity effects of hexane extract of stem bark of S. baccatum. The toxicity effects were assessed through observation of physiological changes of th

A rigid-flexible manipulator may be assigned tasks in a moving environment where the winds or vibrations affect the position and/or orientation of surface of operation. Consequently, losses of the contact and perhaps degradation of the performance may occur as references are changed. When the environment is moving, knowledge of the angle α between

This paper presents the results of an experimental work carried out to find the wall pressure distribution in a suddenly expanded duct. The enlarged duct is attached to the exit of a convergent- divergent axisymmetric nozzle. The area ratio (i.e. ratio between cross sectional area of the sudden expansion duct and the nozzle exit area) considered in

POF (Plastic Optical Fiber) is more suitable than the quartz optical fiber for indoor LAN (Local Area Network), for example in-home or office networks because of its flexibility and ease of connection by relatively large core diameter.1 x 2 optical switches for indoor LAN using POF have been developed. For switching by movement of a POF, large disp

Play is children’s natural tendency and widely regarded as providing a rich context for children’s learning in the field of early childhood education. A commitment to play has underpinned many traditional approaches to early childhood curriculum. Pertaining to the matter of partnership with parents, there was evidence indicating that many pre-s
