In order to establish groundwater sustainability indicators for the Vietnam capital, Hanoi, in this study, the sustainability assessment framework of groundwater resources from an economic perspective is proposed for the first time with the focus of Hanoi current groundwater problems. An AHP （Analytical Hierarchy Process） approach is employed to generate the main components （aspects and indicators） of this framework, because development of composite indicators is considered to be a best approach for sustainability evaluation. To do this, the current problems of Hanoi groundwater resources were carefully reviewed and explored to propose three main aspects （quantity, quality and management） and appropriately construct their 9 MESIs （Macroeconomic Sustainability Indicators）. As for the results, the sustainability indices of the quantity, quality and management aspects were appropriately assessed as good, excellent and good sustainability levels, respectively. As a result, the sustainability of Hanoi groundwater resources development is economically good, indicating that there has been a big effort to improve the groundwater sustainability from both sides, the local government and communities.展开更多

One single Key Performance Indicator （KPI） is mainly employed to evaluate equipment in most studies, neither integrating the KPIs into a completed evaluation system nor considering the impact and conflict among KPIs. In this paper, a KPI evaluation architecture is presented to define and analyze KPIs, and then a common structure for KPI to obtain the KPI set of manufacturing equipment is introduced. An available multi-KPl coordination model is proposed to discern and balance the relationship among multi-KPl. Finally, a case study is introduced to illustrate the applicability of the coordination model by using multi-objective optimization strategy and an efficient solution is obtained.展开更多

We developed muscle hardness testers to assess muscle hardness digitally from the reaction force and the depth in pushing a finger-shaped indenter, thereby simulating palpation. To assess muscle hardness digitally, we proposed this means using the reaction force and depth that are measured when the indenter is pushed, along with the elastic constant, and the differential elastic modulus. The tester is designed to be useful to ascertain effects of, or follow the course of, muscle layer treatment applied for shoulder stiffness and other conditions. As described herein, we confirmed the effectiveness of digital assessment using foam rubber consisting of an upper layer and a lower layer, respectively simulating the cortical and muscle layers of a human body. Additionally, monitoring six subjects, we digitally assessed the change of hardness of the trapezius muscle by changing the position of the upper extremity. Next, we were able to measure the change of hardness before and after treatment for 21 subjects with shoulder stiffness.展开更多

Using a sample of 16 Czech firms, we attempt to measure the scope and size of the differences in the selected set of financial ratios as calculated with data reported according to the traditional Czech accounting standards （CAS） and under the IFRS provisions. Our study discovers that there are important differences resulting from the two reporting formats. Our research comes to a conclusion that translation of Czech statements to IFRS may cause changes in the values of financial indicators without relationship to the real change in the firms＇ value, performance, and stability. Even though the findings were not statistically significant, the indicative results of our measurements disclosed an important fact that the transition to IFRS could cause deterioration of key indicators and thereby could impact on the overall rating of companies. One needs to be cautious with generalization due to the small sample size.展开更多

A proper action in this regard requires the existence of appropriate bases and investing tools and techniques in the capital market. One of these effective methods which is considered as the basis of new investment strategies, in addition to multiple unique features, is called index tracking. By considering the undeniable role of this approach in the future of capital markets, its investigation and implementation have been considered in this research and so the problem of optimal Tehran Exchange Dividend Price Index （TEDPIX） tracker fund selection is studied using a hybrid approach of genetic algorithm and quadratic programming. Neural network was applied to simulate unavailable data. Results illustrate the exactness and acceptable performance of the formed portfolios in several iterations such that achieving similar and even better performance compared to the index is a distinctive characteristic of the proposed algorithm.展开更多

From satellite imagery： U1 （urban index） and NDVI （normalized difference vegetation index） were calculated and used that information to construct urban density and vegetation distribution maps of the study area. Urban density and vegetation distribution were combined to estimate urban environmental condition; then compared to socioeconomic conditions. The results revealed that the Semarang Municipality had a higher percentage of developed or urbanized areas （49%） compared to the percentage of area covered by vegetation （42%）. In general, southern Semarang had a higher quality urban environment and socioeconomic condition compared to northern Semarang, which had a higher urban density, lower quality urban environment and lower socioeconomic condition. The indicate that socioeconomic condition can be determined using satellite-derived urban and vegetation indices even in places like Semarang Municipality, where the population settlement was sparse and unorganized.展开更多
