Fall-from-heights have historically been the major cause of fatalities in the construction sector, accounting for around one-third of all fatalities in the construction industry. this type of risk can be prevented or mitigated during the design phase through an innovative safety management approach called Prevention through Design (PTD). However, past research suggests that the lack of PTD tools is one of the reasons for the slow adoption of PTD among designers. thus, the current study aimed to develop a BIM-based automated fall hazard identification as a designer’s tool for PTD. A BIM-based PTD framework for structural designing has been developed and evaluated through a case study. Results have reinforced the viability of BIM software as a tool for PTD analysis in structural designing.

Data exploration helps to gain understanding of the dataset and the system itself. there are methodologies to handle large number of sensors as well. In this paper operational states are defined to interpret physical behaviour in a soil ecosystem. Dimensionality reduction is achieved with Principal Component analysis (PCA) method giving another view to the soil dataset from spring term. K-means algorithm groups data densities by clustering the data. this grouping is the basis for defining operational states in the system. Soil data as a part of an ecosystem involves specific features. In the applied approach dynamic visualization including animations constitute an important exploration view. All experiments are realized in Jupyter programming environment with Python 3 programming language. Related literature about data visualization is reviewed. Combining methods and tools withthis data as a result soil ecosystem features are recognized.

In recent years there has been a considerable effort in optimising formal methods for application to code. this has been driven by tools such as CPACHECKER, DIVINE, and CBMC. At the same time tools such as UPPAAL have been massively expanding the realm of more traditional model checking technologies to include strategy synthesis algorithms - an aspect becoming more and more needed as software becomes increasingly parallel. Instead of reimplementing the advances made by UPPAAL in this area, we suggest in this paper to develop a bridge between the source code and the engine of UPPAAL. Our approach uses the widespread intermediate language LLVM and makes recent advances of the UPPAAL ecosystem readily available to analysis of source code.

In the process of subway construction, there is a complex nonlinear relationship among the engineering quantity, material cost, labor cost and total cost, which cannot be accurately calculated by manpower alone. therefore, the reasonable deployment of human, material, capital and other resources in the future requires a high-precision and highly reliable analysis and prediction model. Aiming at this problem, this paper proposes a Bayesian network model of subway construction project cost prediction based on principal component analysis and K2 algorithm on the basis of analyzing the financial data, contract data and the existing engineering quantity calculation data in the information data system. Firstly, the principal component analysis method is used to screen the influencing factors of subway mechanical and electrical engineering and extract the core data features. Based on the extracted features, a Bayesian network model was built according to the principle of K2 algorithm to dynamically analyze the engineering cost, and the actual subway engineering cost data was used to train, verify and predict the model. the experimental results show that the accuracy of the prediction model proposed in this paper is 87.5%, and the prediction results are completely within the controllable range, thus proving the effectiveness of the model and realizing the dynamic tracking of the construction cost of electromechanical engineering.

In the current era of architecture, sustainability and energy efficiency are becoming increasingly important, while at the same time, advanced technological tools and analytical methods are reshaping the design and construction of buildings. Architects must think responsibly and globally, as buildings account for a significant proportion of the world's energy use. As architects, we have a responsibility to create ecologically optimal facilities for the long term. Withthis in mind, we would like to present applications that trace the chronological milestones in the development of energy analysis. this paper provides a detailed overview of the different methods of energy analysis. the methods include software developed specifically for energy analysis, an analysis add-on built into modeling software, and among the more innovative technologies, we have also examined parametric design and methodologies based on artificial intelligence algorithms. We have tried to select these methodologies and software in a diversified way to get a more comprehensive picture of how they work. the main aim of this paper is to compare the conclusions drawn from case studies of our previous energy research and from the studies of these energy software, partly subjectively and partly with an objective perspective that tightens subjectivity. As such, a set of criteria we have defined will guide the structure of this analysis. In this article, we will try to highlight the advantages and disadvantages of each method, and we will also try to consider the importance of 3D model-based analysis.

the circular economy principles are examined in the context of developing integrated information technologies. A conceptual model for managing circular economy projects is presented, encompassing three management levels to ensure strategic sustainability. As an illustrative example, the business model of establishing an agrarian-industrial complex of energy-independent enterprises based on circular economy principles is explored. this model encompasses the comprehensive infrastructure of the agrarian-industrial complex, incorporating hybrid project management methodologies and an innovative development program. the application of process models, the waterfall life cycle, Agile models, and various project management methods are utilized. throughout the analysis of the business case, the architecture and interaction schemes of the program withthe environment during its implementation are determined.

the problem of constructing a complex composite indicator based on expert scores and statistical information about particular indicators is considered. A procedure for estimating the parameters of a nonlinear model of a composite indicator based on the method of biased kernel ridge regression is proposed; at the same time, the problem of optimal concordant of expert and statistical information is solved by choosing the appropriate regularization functional. Using the method of Lagrange multipliers, expressions for estimating the parameters of a nonlinear model and a kernel-based model of a composite indicator are obtained. the results of a numerical experiment on the construction of a composite indicator model using real data are presented.

Processing biomedical image data, specifically microscopic data from a blood sample, where it is necessary to identify and classify leukocytes, is a complex issue. Manual processing of such data is time-consuming and can be subjective and prone to human error. therefore, this work aims to analyze current processing techniques and available tools to simplify and automate this process. the paper includes an overview of the biomedical data used, and describes the analysis, the selection of the relevant data, a proposal for a solution using the general methods and overall automation of the process, an implementation of the solution, and an evaluation of its benefits in further research. Logistic regression was used to predict the leukocyte type, in combination withthe active learning approach. the work results in a solution that simplifies and mainly speeds up the processing of microscopic data for leukocyte identification and classification by removing the human error and subjectivity. the proposed solution achieved classification accuracy of 92% in both training and testing dataset (Raabin-WBC) and 84% on vakidation dataset (BCCD), without any changes in the model parameters. this solution may find application in diagnosing various diseases such as blood cancers, infections, autoimmune diseases, or allergies.
