Optimizing the geodetic networks based on the distances between the net points and the project border

Geodetic networks are important for most engineering projects. Generally, a geodetic network is designed according to precision, reliability, and cost criteria. This paper provides a new criterion considering the distances between the Net Points (NPs) and the Project Border (PB) in terms of Neighboring (N). Optimization based on the N criterion seeks to relocate the NPs as close as possible to PB, which leads to creating shorter distances between NPs or those distances linking NPs with Target Points (TPs) to be measured inside PB. These short distances can improve the precision of NPs and increase the accuracy of observations and transportation costs between NPs themselves or between NPs and TPs (in real applications). Three normalized N objective functions based on L1, L2, and L∞‒norms were formulated to build the corresponding N optimization models, NL1; NL2; and NL∞ and to determine the best solution. Each model is subjected to safety, precision, reliability, and cost constraints. The feasibility of the N criterion is demonstrated by a simulated example. The results showed the ability of NL∞ to determine the safest positions for the NPs near PB. These new positions led to improving the precision of the network and preserving the initial reliability and observations cost, due to contradiction problems. Also, N results created by all N models demonstrate their theoretical feasibility in improving the accuracy of the observations and transportation cost between points. It is recommended to use multi-objective optimization models to overcome the contradiction problem and consider the real application to generalize the benefits of N models in designing the networks.

Survival is the driver for adaptation: safety engineering changed the future, security engineering prevented disasters and transition engineering navigates the pathway to the climate-safe future

Consider a simple idea describing the time, space and relationship scales of survival. Engineering has been going along with the current paradigm that growth in wealth and material consumption can continue through innovation and technology development. The proposed survival continuum concept represents a new way to think about sustainability that has clear implications for influencing engineering projects in all fields. The argument for survival as the driver for adaptation is developed sequentially, building on theory, definition, examples and history. The key idea is that sustainability will be effectively addressed by a new engineering discipline furthering development of the field of safety engineering with longer time scale, broader space scale and more complex relationship scale. The implication is that the past 100-year development of safety engineering can be leveraged to fast-track the inclusion of sustainability risk management throughout the entire engineering profession. The conclusion is that a new, interdisciplinary field, Transition Engineering, is emerging as the way our society will achieve sustainability-safety through rapid reduction in fossil fuel use and reduction in detrimental social and environmental impacts of industrialization.

Engineering projects and educational paradigms

Engineering is part of one of the most forward-thinking careers in industries. In this work, the elementary principles of engineering projects in university education are evaluated and the minimum criteria that an engineering project should have are established so that the future professional develops the necessary skills for their performance as an engineer. A bibliographic review of engineering education is then carried out and the formulation of projects that make the development of practical skills possible.

Association Mining of Near Misses in Hydropower Engineering Construction Based on Convolutional Neural Network Text Classification

Accidents of various types in the construction of hydropower engineering projects occur frequently, which leads to significant numbers of casualties and economic losses. Identifying and eliminating near misses are a significant means of preventing accidents. Mining near-miss data can provide valuable information on how to mitigate and control hazards. However, most of the data generated in the construction of hydropower engineering projects are semi-structured text data without unified standard expression, so data association analysis is time-consuming and labor-intensive. Thus, an artificial intelligence (AI) automatic classification method based on a convolutional neural network (CNN) is adopted to obtain structured data on near-miss locations and near-miss types from safety records. The apriori algorithm is used to further mine the associations between “locations” and “types” by scanning structured data. The association results are visualized using a network diagram. A Sankey diagram is used to reveal the information flow of near-miss specific objects using the “location ⟶ type” strong association rule. The proposed method combines text classification, association rules, and the Sankey diagrams and provides a novel approach for mining semi-structured text. Moreover, the method is proven to be useful and efficient for exploring near-miss distribution laws in hydropower engineering construction to reduce the possibility of accidents and efficiently improve the safety level of hydropower engineering construction sites.

Integrated Product, Process and Manufacturing System Development for Multifunctional Micromachine Tool

Novel practices in the formation of students are encouraged to be multidisciplinary which in fact, allows them to better understand the behaviour of systems. This skill allows them to identify existing needs that impact multiple areas, both for an organization and to complement their entrepreneurial training. In this work, there is exposed a reference framework that arose to aid in the innovative design process among the manufacturing sector, it seeks to stretch the gap between conceptualization and implementation for engineering projects. Furthermore, the formation of the learners is enriched due to the breakdown of complex systems into entities as it gathers existing knowledge and provides structure to systematize the development process, allocate problems and provide feedback. Thus, design stages are detailed, engineering stages are described, and a toolbox is presented to guide designers into their task. The methodology has been tested under multidisciplinary projects in different time lapses, observing a positive impact in the formation of participants, as it guarantees the inclusion of desired attributes, documentation and milestones in the scenario being developed. In this article, there are described three case studies. Findings when developing using the methodology shows a structural, documented process followed by the designers, capable of recognizing the abilities acquired and reinforced skills, documented entities corresponding to what is developed at the end of the projects and time of deployment is enhanced.

Sediment Control At The Lateral Channel Inlet

Environmental and civil engineering projects frequently employ the open channel side intake structure. However, the commonest among the issues faced in most of the lateral intakes include sedimentation and sediment delivery. This involves several problems namely, decreased flow discharge capacity in the irrigation canals and the threat of water blockage during times of low water flow. Besides, this problem with the sediment either lowers the performance levels or causes failure of the facilities that this sub-channel serves. Hence, the engineers focused on designing an intake with the features of high flow discharge and low sediment delivery. This paper attempts to review and summarize the literature relevant to the branching channel flow and submerged vane technique to minimize the sediment-related issues. The present review highlights that most of the earlier research work done dealt with the characteristics of the flow in a right-angle branch channel possessing rigid confines. Also, more investigations are required regarding the implications of the submerged vanes. Besides, no comprehensive studies are available on the saddle point itself, and a high percentage of the studies have been part of earlier investigations that had focused on only briefly outlining this subject.
