At the beginning of 1938 the faculty opened with four professors and six students. This article briefly investigates the contribution of four professors who taught the Old Testament. As a rather conservative theologian J H Kritzinger strongly emphasized the importance of a scientific approach to Old Testament and of sound exegetical study. He was succeeded by A H van Zyl who had a more historical approach to the Old Testament, took the histori

Abstract:

While some philosophers have posited Judaism and Hellenism as opposites, interesting collaboration has always taken place in the liminal spaces between the two poles. In this article, I explore one such space: the bathhouse. I draw on two stories from different epochs and places: Rabban Gamliel’s interlocution with Proclus ben Philosophus in second-century Akko; and Rabbi Lionel Blue’s experience with Rabbi Dr Werner van der Zyl in twentieth-century Amsterdam. Based on these two stories, I argue that certain spaces allow for collaboration, wherein seemingly contrasting cultures can be reconcil

Abstract:

In the diverse applications of polarimetric Synthetic Aperture Radar (SAR) systems, it is a crucial to conduct polarimetric calibration, which aims to remove the radar system distortion effects prior to utilizing polarimetric SAR observations. The objective of this study is to evaluate the performance of different polarimetric calibration methods. Two widely used methods, the Van Zyl and Quegan methods, and one recently proposed method, such as the Villa method, have been selected among various calibration methods in literature. The selected methods have basic differences in their assumptions

Abstract:

The 1970s saw a significant increase in the volume of research on individuals’ subjective experience of well-being. The subjective well-being of university students has received less attention, however. Student well-being is important, given the widespread concern over the high dropout rates at institutions of higher learning in South Africa (Council of Higher Education, 2013; Van Zyl, 2010). The paper adds to the existing body of literature through an exposition on the possible influence of variables forthcoming from the literature, on the overall subjective well-being of first-year economics

Abstract. In this paper, we present two radar vegetation indices for full-pol and compact-pol SAR data, respectively. Both are derived using the notion of a geodesic distance between observation and well-known scattering models available in the literature. While the full-pol version depends on a generalized volume scattering model, the compact-pol version uses the ideal depolariser to model the randomness in the vegetation. We have utilized the RADARSAT Constellation Mission (RCM) time-series data from the SAMPVEX16-MB campaign in the Manitoba region of Canada for comparing and assessing the i

Abstract:

The Japanese ALOS-2 satellite was launched on May 24<sup>th</sup>, 2014. It has the L-band SAR, PALSAR-2. Kim,Y. and van Zyl, J.J. proposed a kind of Radar Vegetation Index (RVI) as RVI = 8 * σ<sup>0</sup><sub>hv</sub> / (σ<sup>0</sup><sub>hh</sub> + σ<sup>0</sup><sub>vv</sub> + 2* σ<sup>0</sup><sub>hv</sub>) by L-band full-polarimetric radar data. Kim, Y. and Jackson, T.J., et al. applied the equation into rice and soybean by multi-frequency polarimetric scatterometer above 4.16 meters

Abstract:

Wu and Sprung (Phys. Rev. E, 48, 2595 (1993)) reproduced the first 500 nontrivial Riemann zeros, using a one-dimensional local potential model. They concluded — as did van Zyl and Hutchinson (Phys. Rev. E, 67, 066211 (2003)) — that the potential possesses a fractal structure of dimension d = 3/2. We model the nonsmooth fluctuating part of the potential by the alternating-sign sine series fractal of Berry and Lewis A(x,γ). Setting d = 3/2, we estimate the frequency parameter (γ), plus an overall scaling parameter (σ) that we introduce. We search for that pair of parameters (γ,σ) that minimizes
