SUMMARY The horizontal-to-vertical spectral ratio (HVSR) of ambient noise is commonly used to infer a site's resonance frequency (${f_{0,site}}$). HVSR calculations are performed most commonly using the Fourier amplitude spectrum obtained from a single merged horizontal component (e.g. the geometric mean component) from a three-component sensor. However, the use of a single merged horizontal component implicitly relies on the assumptions of azimuthally isotropic seismic noise and 1-D surface and subsurface conditions. These assumptions may not be justified at many sites, leading to azimuthal variability in HVSR measurements that cannot be accounted for using a single merged component. This paper proposes a new statistical method to account for azimuthal variability in the peak frequency of HVSR curves (${f_{0,HVSR}}$). The method uses rotated horizontal components at evenly distributed azimuthal intervals to investigate and quantify azimuthal variability. To ensure unbiased statistics for ${f_{0,HVSR}}$ are obtained, a frequency-domain window-rejection algorithm is applied at each azimuth to automatically remove contaminated time windows in which the ${f_{0,HVSR}}$ values are statistical outliers relative to those obtained from the majority of windows at that azimuth. Then, a weighting scheme is used to account for different numbers of accepted time windows at each azimuth. The new method is applied to a data set of 114 HVSR measurements with significant azimuthal variability in ${f_{0,HVSR}}$, and is shown to reliably account for this variability. The methodology is also extended to the estimation of a complete lognormal-median HVSR curve that accounts for azimuthal variability. To encourage the adoption of this statistical approach to accounting for azimuthal variability in single-station HVSR measurements, the methods presented in this paper have been incorporated into hvsrpy, an open-source Python package for HVSR processing.

Purpose. The effectiveness of the development of an information system for quarry management is primarily determined by the level of geological and surveying support (GSS), which includes solving such basic tasks as calculating reserves (operational and complete), accounting for ore mining, building the information base for mining planning and management, and field modeling, and career, ore body contouring, etc. The purpose of this work is to develop and use B-Splines in the automation of geological surveying software in the quarry. Research methods. The basis of many tasks is the construction of surfaces. For the first time in recent years, an uneven rational Bspline (NURBS) is used to describe them, which most fully satisfies the following criteria: the model's adequacy to the real representation, the efficiency of model formation and surface construction, and the visualization of the model in three-dimensional space. Scientific novelty. The advantages of constructing surfaces using NURBS are as follows: ease of calculation; sufficient smoothness; construction of the surface of any degree of complexity; using the weights of the control points, control of the surface (it can pass strictly through the specified control points). The latter property made it possible with the help of a NURBS surface to effectively model the day surface of a quarry with a strict passage of the surface through points of the ledges. Practical significance. For the joint Russian-Mongolian enterprise Erdenet (Mongolia), developing the copper-molybdenum deposit, an integrated automated GSS system has been developed and has been in operation for many years. Software and algorithmic tasks of the system are constantly being improved. This article presents its latest developments and development paths. The use of NURBS allowed us to construct the day surface of the open-pit mine, to improve the complete calculation of reserves, the accounting of ore mining, and the delineation of ore bodies along the open-pit horizons. Results. The software is implemented in C++ and C# for Windows. To build three-dimensional graphics, the tools of the open graphic library OpenGL are used. Separate modules of the developed GSS system were used at the Novokrivoyorogsk and Ingulets mining and processing plants. The methodology for constructing automated GSSs has been approved by many years of positive experience in industrial implementation and can be used for non-ferrous ore and iron ore deposits.

Introduction: Urinary stone disease is a common urological problem. Chemical analysis of the urinary stones is a part of metabolic evaluation of first time or recurrent stone formers. The report of chemical analysis of stones may obviate the need for complete metabolic evaluation or can direct metabolic evaluation. In this study we aim to find out the chemical compositions of urinary stones in our population, so that the result might serve as a baseline for the related research in future. Methods: A prospective study was carried out in our institute with the qualitative chemical analysis of urinary stones. All patients operated for different urinary stones by various methods were included in the study. Statistical analysis was done by using Statistical Package for the Social Sciences Software (SPSS) Program for windows ® version 18. Results: A total of 55 patients were included in the study. Male to female ratio was 1.75. Mean age was 41.45 years. Ureteric and renal stones were most common accounting to 49 and 31 percentage respectively. All stones contained calcium. Calcium, phosphate, oxalate and uric acid were the major constituents of the stones representing 100, 94.5, 85.5 and 80 percentage of the stone specimen. Other constituents were amino acids, carbonate, magnesium and cystine. Conclusions: Urinary stones are of mixed chemical compositions. Further large scale prospective studies along with other parameters of metabolic work up are recommended to know more about the chemical compositions of urinary stones and its utility in clinical practice.

Purpose The skyrocketing rise of Islamic banking is noticeable in not only Islamic countries but also non-Islamic countries during the past few decades. Many conventional banks have started Islamic banking generally by maintaining separate branches/windows and occasionally by pursuing a complete conversion strategy. Following the global trend, two of the full-fledged Islamic banks adopted a conversion strategy consecutively in 2004 and 2008 in Bangladesh. The number of the conversion case is still limited. At this backdrop, this study aims to identify the incentives in the conversion strategy into Islamic banks. Design/methodology/approach Using the secondary data from the annual reports of the sample banks for both pre- and post-conversion periods, this study adopts the “case study” approach upon the comparison with the performance of conventional banks and other types of Islamic banks. Findings It is apparent that higher reserve requirement for conventional banks provides the incentive for the conversion into Islamic banks given with less reserve requirement. Under the protective regulatory framework, these converted Islamic banks may have enjoyed the rent for learning during the initial phase after the conversion, even though majority of the funds of these banks are collected from high-cost mudaraba time deposits. Basically, the credit strategy of the converted banks has been quite conservative, resulting in the concentrated portfolio selection on the asset-backed financing. However, the recent engagement of these banks in the Shari'ah-based participatory financing makes their performance a bit vulnerable. Research limitations/implications It is becoming difficult to justify a protective regulatory framework for incubating infant Islamic banks if the rent for learning given under the framework would not encourage them to challenge and absorb the risk and uncertainty associated with Shari’ah-based participatory financing. The current mode of profit–loss sharing (PLS) makes it difficult for the regulators to create an appropriate incentive for Islamic banks to challenge the equity-based financing. Originality/value The number of the conversion case is limited. Less has been done to investigate the reasons why the conventional banks opt for the conversion into Islamic banks, particularly in Bangladesh.
