The article discloses methodological approaches to quantifying the level of penetration of block chain technologies into the regional socioeconomic environment in comparison to the supply chain strategies. Based on the methods of mathematical and statistical analysis, it allows you to formalize and convert a large array of data of a qualitative order into a single scale for measuring the process under study - the level of demand in the regional socio-economic environment for block chain technology.

This aim of this study is to measure the technical efficiency score and identify the factors that affect the technical efficiency in plastic manufacturing firm in Malaysia for the year 2015 using the two stage Data Envelopment Analysis (DEA) method. The first stage involves calculating the efficiency score through the DEA using firm-level data, provided by the Department of Statistics, Malaysia. In the second stage, Tobit Regression Analysis was used to identify the significant factors affecting the efficiency of the plastic industry.

This thesis describes a quality method that was developed to measure the quality of a tool or technique based on the results it produces. Based on the results of these measurements on current carving tools, a number of areas were identified that could be improved. A new carving framework was developed to address these points of improvements, and its results were tested using the previously developed quality method. The new carving framework achieved significantly better results on all identified improvement areas.

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The primary aims of this thesis are: A) to measure the dependence of the DAPR20,10 on the size of the primary small photon field, and to relate this data to TPR20,10 of the reference field. B) to develop a method of using a large-area ionization chamber to compare the measured dosearea product to that calculated by a treatment planning system. C) To gain further understanding of the dose-area product by supplementing the results with 2D high resolution film dosimetry.
