This article introduces a method which could quickly delineate short-circuit fault location by establishing the corresponding matrix between nodes on grid and short circuit current value. A 22kV Daklak distribution grid – E471 line is studied. A big data of input as load, source, season coefficient, utilization coefficient and all four types of short circuit have been considered and calculated in detail.

In the multi-dimensional model of data warehouses, data drawn from multiple sources is organized into fact tables and dimension tables. Data cubes pre-compute the aggregations of measurements along combinations of dimensions to speed up the processing of Online Analytical Processing (OLAP) queries. When the underlying fact tables or dimension tables change over time, data cubes need to be incrementally maintained to reflect these changes. In this thesis, we study the problem of incrementally maintaining data cubes under slowly changing dimensions.

This thesis examines the influence of market (Narver & Slater, 1990), learning (Sinkula, Baker, & Noordewier, 1997), and entrepreneurial orientation (Lumpkin & Dess, 2001) as sources of competitive advantage in rapidly growing small-to-medium enterprises (SMEs). The present thesis incorporates two studies (Study 1 and Study 2), utilizing a sequential explanatory design, which is characterized by undertaking quantitative data collection and analysis, prior conducting qualitative research (Cresswell, 2003).

Despite titanium (Ti) and zirconium (Zr) minerals being critical, often irreplaceable, and generally unrecyclable components of modern materials, there is very little understanding on the constraints affecting their availability within the public literature. And while co/by-products such as hafnium (Hf), vanadium (V), garnet, and rare earth elements (REE) add significant value to the extraction of these minerals, they suffer from the same level of recyclability and understanding as Ti and Zr minerals.

In addition to the physical parameters such as magnetization intensity distribution, the volume and the shape of the magnetized material, directions of the magnetization and the ambient field, the distance between the observation surface and the causative sources significantly affects the shape and the amplitudes of the magnetic anomalies. Aeromagnetic surveys are performed using either a draped surface or a constant elevation plane above sea level. These surveys can easily reconnoiter large territories in a short time.

For this purpose, it has been attempted to determine new geological, seismological and environmental data by examining a large number of original sources, records and old international earthquake catalogs, other than the existing national catalogs used in seismicity studies in Turkey. In this context, a new local and updated historical earthquake catalog was prepared for İzmir and its immediate vicinity. The data obtained from the records show that the maximum intensity of some destructive historical earthquakes in the İzmir region was X.
