Perceptual uncertainty and environmental volatility are among the most enduring challenges in robotic research today. Contemporary robotic systems are usually designed to work in specific and controlled domains where a total number of variables is defined. Traditional solutions therefore often result in over-constrained interaction spaces or rigid system architectures where any unexpected change can result in system failure. The focus of this work is set on achieving a constant adaptation of the system to changes through interaction. A computational mechanism based on the entropy reduction method is integrated along with the three-component control model. This model is seen as a context-to-data interpreter used to provide context-aware reasoning to the technical system. The mechanism is using a decrease in interaction uncertainties when proofs are provided to the system. In this way, the robot can choose the right interaction strategy that resolves reasoning ambiguities most efficiently

Today's age is characterized by large amount of information that surrounds us in which visual information plays a significant role. Nanosensor air quality measurement systems that use Internet of Nano-Things technology enable the collection of big data. Ease of display and storage of information that the user can easily interpret are imperative in designing a visual interface. Only a good combination of visual elements complemented by data and map display will contribute to the clarity of the processed data. This paper will give an overview of the factors that affect the excellence of the transmission of visual information. Ways of presenting visualizations of air quality data measured by IoNT systems will be discussed through descriptive and empirical analysis of visualizations. A special emphasis is on the review of existing practices and principles, and the possibilities of visual presentation of information in this area will be explained through the discussion.

Robotic process automation (RPA) is a technology for office automation to imitate human behaviour when interacting with computers to perform digitized tasks manually, such as opening and closing applications, reading documents, entering data, and sending e-mails. As with any new digital technology answering the question of where to start and what is the right software, is challenging. In the case of RPA, the question of where to start depends on the selection of the business process to be automated and optimized. There are approaches for process selection in research, but they are relatively complex and have not been validated in practice. To fill this gap, we have simplified the process selection method and validated it on a practical example. We also present a simple method to select the appropriate RPA software. The criteria selection and evaluation were done with the Pairwise Comparison and Benefit Value Analysis method. This approach is relatively easy to follow and to apply in practice and thus also closes a gap in applied research.
机器人流程自动化(Robotic process automation, RPA)是一种办公自动化技术，它在与计算机交互时模仿人类的行为，手动执行数字化任务，如打开和关闭应用程序、阅读文档、输入数据和发送电子邮件。与任何新的数字技术一样，回答从哪里开始以及什么是正确的软件的问题是具有挑战性的。在RPA的情况下，从哪里开始的问题取决于要自动化和优化的业务流程的选择。研究中有一些工艺选择的方法，但它们都比较复杂，并没有在实践中得到验证。为了填补这一空白，我们对工艺选择方法进行了简化，并通过实例进行了验证。我们还提出了一种简单的方法来选择合适的RPA软件。采用两两比较和效益价值分析法进行标准选择和评价。这种方法在实践中比较容易遵循和应用，从而也弥补了应用研究的空白。

Although many studies have investigated the effects of thermal bridges on building energy performance, multidimensional thermal humidity analysis of building coatings remains a challenge due to multiple problems such as complexity of modeling, computer analysis execution time, numerical convergence restraints, and numerous properties related to humidity. The study’s main aim is to investigate the effects of moisture bridges on building performance and provide appropriate preventive solutions. In this study, thermal-humidity simulation for evaluating heat and mass transfer in walls of a historic building (building No. 4, Tehran University of Arts, The National Garden Campus) was analyzed using WUFI 2D software. This study evaluated the effectiveness of executive details used in the studied building and compared the performance with recent common details. The obtained results indicate that the information obtained from the moisture and heat audit of the building should be investigated simultaneously and the results lead to a solution to reduce the heat transfer and minimize condensation risks. Appropriate solutions have been studied, according to the conditions of each building element.

This paper presents a digital material planning approach, utilizing simulation-based optimization to select and parametrize article specific demand forecasting methods. Demand forecasts are the basis of material requirements planning in consumption-based material planning, and are an essential lever for efficient inventory and order calculation. Despite their acknowledged potential, digital tools for optimized demand calculation are still lacking in practice. Thus, the goal of the presented approach to provide an applicationoriented method to optimally select and parametrize state-of-the-art forecasting methods, based on product-specific demand data. In this approach, a rule-based selection heuristic is combined with static simulation of demand time-series and a metaheuristics-based optimization of forecasting parameters, to provide automatically optimized article-specific demand forecasts. Case studies for two companies in the capital goods industry evaluate and quantify the application potential. The results point to significantly improved, itemspecific demand planning

The advancing digital transformation is increasing the cost pressure on companies. People’s work performance needs to be re-evaluated. Therefore, efficient HumanResource-Controlling (HR-Controlling) with increased use of technologies promises companies a sustainable improvement in their financial situation. This paper shows the potential of the recent digital technologies on HR-Controlling, such as Big Data or Advanced Analytics. To demonstrate the impacts of the digital transformation on HR-Controlling, an empirical study with Austrian companies has been done. As a result, the most promising technologies for each stage in the HR-Controlling-loop are shown to increase the efficiency in HR-Controlling.

Resilience is a new approach to assessing and enhancing the resilience and resilience of the foundations of development in cities. Explaining and recognizing its effective and promotional components can pave the way for many programs related to crisis management and passive urban defense, which is very necessary given the complexities of today's threats. Different dimensions of human society resilience are examined in the physical, social, economic, environmental-institutional fields. In fact, resilience as a framework goes back to a concept that can easily relate to all stages and sections of disaster and crisis management. In this regard, the present study has been compiled with the aim of evaluating the dimensions of economic-physical resilience of cities around the metropolis of Tehran in the Islamshahr region. In this study, first through library studies, indicators and factors affecting economic and institutional resilience were identified and operational defined, then using a questionnaire in the form of hierarchical analysis process, the final weight of indicators by domestic experts and External was determined. Descriptive and inferential statistics (one-sample t-test and Friedman test) were used to analyze the data. Institutional resilience with an average of 2.5325, infrastructure resilience with an average of 2.4377 and urban resilience with an average of 2.3786 is therefore urban resilience and components of urban resilience in Islamshahr city are at a low level.

In this study, e-commerce satisfaction and sales growth by considering the role of trust in social commerce are examined. In a trust-based environment, tools such as coercion to secure trades lose their effectiveness. Instead, people are willing to pay back and believe in honesty. Trust fosters market work, increases the willingness of individuals to interact and collaborate with groups, and provides a thriving network of voluntary gatherings. Trust, on the other hand, affects a person's satisfaction, purchase intention, and buying behavior. This study is conducted to examine e-commerce satisfaction and sales growth by considering the role of trust in social commerce. Therefore, a model is proposed to achieve the main goal using structural equation modeling (SEM). The hypotheses are then tested using Amos and 22spss software. In the inferential statistics section, the normal distribution of the variables is first examined using the Smirnov-Kolmogorov test. Since the significance level of all variables is higher than 0.05, it can be claimed that all variables are normally distributed. In the factor analysis section, the sample adequacy is examined using KMO and Bartlett's test. The hypotheses are then tested using Amos software and regression in SPSS software.

The Green Deal published by the European Commission in 2019 pursues the goal of a climate-neutral continent. Its guidelines cover sustainable finance, industry, and energy supply, among other areas. Choosing sustainable investment and finance promotes the shift to a more carbon neutral, circular and environmentally conscious economy and underpins financial stability. Companies that want to remain competitive must embrace sustainable business practices. This means considering sustainable investments and corporate financing along the value chain. In this article, we will show which sustainable forms of financing are available to companies - analysing Austrian industrial companies. Furthermore, it will be worked out when investments are to be judged as sustainable and what kind of sustainable investments are made by the companies surveyed.

Data converters are intermediate circuits used to connect between two analog and digital ranges. Data converters are not only used for converting audio into a microphone or speaker, but also for converting audio into a camera or display, transferring information to a computer or digital signal processor. At these times, the need for data converters is not invested in every aspect of life. Digital to analog converters is a leading part of these converters, which are widely used in most audio and video circuits. In this thesis, we have proposed a 4-bit 1GS/s DAC for CUWB-IR usage. To enhance the above performance with superior speed and the need for linearity, every significant block containing the convenient sources, current switches, and deglitcher were designed optimally and a new DAC converter circuit was developed which improves the linearity. The designed DAC was performed using a commercial 130 nm CMOS process. DAC INL/DNL≤0.22LSB features more than high Nyquist bandwidth at extremely low power losses of 0.45 mW. The proposed DAC achieves the best FoMs at the right time for advanced DACs
