Oil a Blessing or Curse: A Comparative Assessment of Nigeria, Norway and the United Arab Emirates
(2018-04)Oil booms have brought unprecedented wealth and development to some countries while in others this has not been the case. The latter is attributed to the resource curse phenomenon which has been explained by the Dutch ... -
On the Design of Circular Fractal Antenna with U-Shape Slot in CPW-Feed
(Scientific Research Publishing, 2010-10)new ultawideband circular fractal antenna with notched-band characteristics is presented. A notched-band characteristic is achieved by employing a U-shape slot in 50 Ω feed lines. The ultra-wideband impedance matching and ... -
On the Economic Premium Principle
(Scientific Research, 2018-02)In this study, we propose an equilibrium pricing rule to capture a characteristic observed in the practical option market. The market has observed that the implied volatility derived from the Black-Scholes formula is ... -
On the solutions of field equations due to rotating bodies in General Relativity
(Polytech, 2017-12)A metric, describing the field due to bodies in stationary rotation about their axes and compatible with a stationary electromagnetic field, has been studied in present paper. Using Lie symmetry reduction approach we have ... -
On Volatility Transmission from Crude Oil to Agricultural Commodities
(Scientific Research, 2017-02)The paper examines volatility transmission from crude oil market to agricultural commodities like wheat, corn, cotton and soybeans. We find that the volatility transmission from crude oil to agricultural commodities ... -
On-Line Measurement of the Chemical Oxygen Demand in Wastewater in a Pulp and Paper Mill Using Near Infrared Spectroscopy
(Scientific Research, 2014-10)Although near infrared (NIR) spectroscopy has been evaluated for numerous applications, the number of actual on-line or even on-site industrial applications seems to be very limited. In the present paper, the attempts ... -
Online-specific fear of missing out and Internet-use expectancies contribute to symptoms of Internet-communication disorder
(Elsevier, 2017-06)Some of the most frequently used online applications are Facebook, WhatsApp, and Twitter. These applications allow individuals to communicate with other users, to share information or pictures, and to stay in contact with ... -
Optical and Electrical Properties of Nanocrystalline SnO2 Thin Films Synthesized by Chemical Bath Deposition Method
(Scientific Research, 2015-10)The chemical bath deposition (CBD) technique was used for the synthesis of the tin oxide (SnO2) thin films. X-ray diffraction (XRD) was employed to find the crystallite size by using Debye Scherrer’s formula. The surface ... -
Optimal M-BCJR Turbo Decoding: The Z-MAP Algorithm
(Scientific Research Publishing, 2011-10)In this paper, we propose a novel idea for improvement performances of the leader M-BCJR algorithm functioning in low complexity. The basic idea consists to localize error instant possibility, and then increase the complexity ... -
Optimal Territorial Resources Placement for Multipurpose Wireless Services Using Genetic Algorithms
(Scientific Research Publishing, 2011-07)This paper presents a study for finding a solution to the placement of territorial resources for multipurpose wireless services considering also the restrictions imposed by the orography of the territory itself. To solve ... -
Optimization of coffee oil extraction from spent coffee grounds using four solvents and prototype-scale extraction using circulation process
(2017-07)The optimization of two parametersdespresso coffee oil extraction time and the ratio of dried spent coffee grounds (DSCG)-to-solventdwere conducted on DSCG employing four solvents. Extracted yields were investigated using ... -
Optimization of extrusion conditions for development of fish-maize based extruded snacks by response surface methodology
(African Journal of Biological Sciences, 2020-04-06)The aim of this work is to study the extrusion process and optimum conditions for development of maize-fish based extruded snacks by using Design-Expert® software for Response Surface Methodology (RSM). However, there are ... -
Optimization of Impedance Plane Reducing Coupling between Antennas
(Scientific Research Publishing, 2011-01)This paper provides a solution for the design optimization of two-dimensional impedance structures for a given elec-tromagnetic field distribution. These structures must provide electromagnetic compatibility between antennas ... -
Optimization of Threshold for Energy Based Spectrum Sensing Using Differential Evolution
(Scientific Research Publishing, 2011-07)Interference threshold based on energy setting in cognitive radios is a non-convex optimization problem [4]. The convergence of optimization techniques like Genetic algorithm (GA) takes several iterations to fix this ... -
Organ Transplant Trade: A Moral Examination
(Scientific Research, 2015-05)This article normatively discusses two moral theories namely: Ubuntu and Deontology, with the aim of arguing against the practice of organ transplant trade. It is argued that this practice violates a rule of categorical ... -
The origin of biological information and programmed protein synthesis
(Scientific Research Publishing, 2013-10)Biological information is one of the most important characteristics of life, and it enables life to evolve to higher complexity and adapt to the environment by mutation and natural selection. However, the origin of this ... -
