Nigeria was given a very low rating in humandevelopment by the United Nations DevelopmentProgramme (UNDP) for the year 2002. This is duepartly to the patriarchal nature of Nigeria, whichemphasizes male education more than that of thefemale. The result is that fewer educated womenthan men are available to contribute to nationaldevelopment activities. The recent introd...

Over the last two decades, anomalous diffusion processes in which the mean squares variance grows slower or faster than that in a Gaussian process have found many applications. At a macroscopic level, these processes are adequately described by fractional differential equations, which involves fractional derivatives in time or/and space. The fractional derivatives describe either history mechan...

Common to a good deal of contemporary philosophical reflection on human identity is the conviction that we are systematically misled, even corrupted, by a picture of the human agent as divided into an outside and an inside— a ‘true self’, hidden, buried, to be excavated by one or another kind of therapy, ranging from the intellectual therapy of the post-Cartesian tradition (the modern ‘philosop...

Inverse scattering methods capable of compressive imaging are proposed and analyzed. The methods employ randomly and repeatedly (multipleshot) the single-input–single-output (SISO) measurements in which the probe frequencies, the incident, and the sampling directions are related in a precise way and are capable of recovering exactly scatterers of sufficiently low sparsity. For point targets, va...

INTRODUCTION Increased frequency and intensity of inpatient therapy contributes to improved outcomes for stroke survivors. Differences exist in the amount of therapy provided internationally. In England, Wales and Northern Ireland it is recommended that a minimum of 45 min of each active therapy should be provided at least 5 days a week provided the therapy is appropriate and that the patient c...

This conductivity is increased by up to 60% by raising the curing pressure from 0.1 to...

Parameter identification problems for partial differential equations usually lead to nonlinear inverse problems. A typical property of such problems is their instability, which requires regularization techniques, like, e.g., Tikhonov regularization. The main focus of this paper will be on efficient methods for determining a suitable regularization parameter by using adaptive finite element disc...

Quantitative photoacoustic tomography (QPAT) offers the possibility of highresolution molecular imaging by quantifying molecular concentrations in biological tissue. QPAT comprises two inverse problems: (1) the construction of a photoacoustic image from surface measurements of photoacoustic wave pulses over time, and (2) the determination of the optical properties of the imaged region. The firs...

In this paper we consider nonlinear ill-posed problems with piecewise constant or strongly varying solutions. A class of nonlinear regularization methods is proposed, in which smooth approximations to the Heavyside function are used to reparameterize functions in the solution space by an auxiliary function of levelset type. The analysis of the resulting regularization methods is carried out in ...
