Abstract. The Pennsylvania Department of Environmental Protection’s Bureau of Abandoned Mine Reclamation (BAMR) implements an Abandoned Mine Land (AML) Emergency Program to address high-priority, abandoned mine land (AML) problems that suddenly occur throughout Pennsylvania’s coal fields. BAMR maintains two field offices: one in eastern Pennsylvania (Anthracite Region) in Wilkes-Barre and one in western Pennsylvania (Bituminous Region) in Ebensburg. Both field offices maintain in-house construction crews with significant equipment available to respond to and address many small AML Emergencies (hazards) such as pothole (or cavehole), subsidences, and mine drainage breakouts. For larger AML Emergencies such as subsidence events causing structural damage to homes, businesses, and roads; mine fires; coal refuse fires; landslides; or other large-scale or complex AML problems, projects are completed by outside contractors. Project designs are completed by BAMR engineering staff. The contractors are then hired through solicitation of bids or proposals with very short timeframes between bid issue and bid opening. Since October of 2010, BAMR has addressed nearly 800 AML Emergencies which equates to approximately 80 AML Emergency projects each calendar year. The average construction cost to address those emergencies was just over $3.25 million per year. Due to the increased precipitation over the Commonwealth the last several years, that number has increased to an average of 86 AML Emergency projects over the last five (5) years (2015–2019) with a record number of 127 addressed in calendar year 2018. The average cost to address those AML Emergency projects over that five-year period was $4.66 million per year. This paper will provide some background on Pennsylvania’s AML Emergency Program, some summary statistics including the annual number and types of projects completed including costs, and also highlight through both photos and video links some typical projects recently completed by the program.

The authors, with the help of a community hospital engineering staff, constructed a modern neurotological testing facility capable of performing on-line computer measurements of vestibulo-oculomotor, visual vestibulo-oculomotor, smooth pursuit, saccade, and optokinetic reflexes. The laboratory was built from component parts and uses a Digital Corporation laboratory computer. Programs from the UCLA Human Vestibular Laboratory were modified to work with the new laboratory. Construction and program modification cost $60,000 and was completed in seven months. The laboratory was working at full capacity six months after construction testing patients with suspected neurotologic and neurologic disorders. The procedures of construction as well as the financial and safety problems are discussed.

This article is devoted to the initial stages of formation and the prospects of development of BIM technologies, the analysis of the general trends, process of formation of uniform resource space and training of professional engineering staff for transport infrastructure. The main objective of this article is the designation, the analysis of problems and formation of a comprehensive approaches within preparation of the modern level of development of design decisions for informational model which is capable to process in a complex an engineering, technological and economic component and will be relevant throughout all life cycle of an object. In articles authors presented results of poll to PGUPS on a subject “to BIM technology: training of specialists in the field of transport constructions” which convincingly show need of preparation and development of engineering potential for BIM introduction. In conclusions the concept of BIM for bridge projection taking into account start of pilot standard projects with use 3D — projections and with engaging of the modern methods of engineering is presented. The article also discusses the prospects for the development of design in Russia.

Modelling Process

Developing the formal model based on the Event-B design pattern is an excellent method to improve the development efficiency of the embedded control system and improve the reusability of the formal model. However, the instantiation of the Event-B design pattern requires the manual writing of a large number of model codes, which brings a great deal of learning cost and coding burden to the engineering staff. In this paper, we propose a modelling approach for formal development of control systems based on the application of iUML-B state machine patterns to model the four synchronization patterns of the typical control system. Then, we use the instantiation of iUML-B pattern state machine to establish a typical multilevel control system's Event-B model. The simulation results show that the event trace of the model obtained using our method is the same as that of the corresponding model obtained using the traditional Event-B design pattern. Compared with the traditional Event-B design pattern method, our method can greatly reduce the manual coding burden in the modelling process. The system model expressed using the iUML-B pattern state machine can be easily mapped to the labelled transition system so as to verify the behavioural properties of the model.

This paper carries out a series of experimental study on 6 column specimens, analyses and compares with the different parameters on the axial loading tests of RC columns and RC columns strengthened with steel tube. The experimental results show that the RC columns strengthened with steel tube take full advantage of loading properties of both materials, thus greatly improve the bearing capacity of specimens. With the same wall thickness steel tube, the improving degree of bearing capacity of long columns is bigger than the short columns, and the reinforcement effect is more obvious. The experimental results can offer reference for scientific research and engineering staff, and promote this reinforcement method to be widely used in engineering practice.
