Design in the chemical industry increasingly aims not only at economic but also at environmental targets. Environmental targets are usually best quantified using the standardized, holistic method of life cycle assessment (LCA). The resulting life cycle perspective poses a major challenge to chemical engineering design because the design scope is expanded to include process, …

Introduction. Software development life cycle (SDLC) is a series of phases that provide a common understanding of the software building process.How the software will be realized and developed from the business understanding and requirements elicitation phase to convert these business ideas and requirements into functions and features until its usage and …
During the software development phase, various software development life cycle models are specified and designed. To guarantee success at each stage of the software development process, each process model …
Thus, no element which life cycle model is followed, the essential activities are contained in all life cycle models though the action may be carried out in distinct orders in different life cycle models. During any life cycle stage, more than one activity may also be carried out. Need of SDLC. The development team must determine a suitable ...

Life cycle assessment (LCA) is a tool to evaluate the total environment impact of a product or process through every stage of its life. This involves a cradle-to-grave approach of the product or process since its environmental impact is assessed from the point of obtaining the raw materials for product development through production, distribution, and its final disposal or …

Selecting a Software Development Life Cycle (SDLC) methodology is a challenging task for many organizations and software engineers. What tends to make it challenging is the fact that few organizations know what are the criteria to use in selecting a methodology to add value to the organization.
Software development life cycle models are like roadmaps used in software development to guide the process from start to finish. They help software development teams work in an organized way and outline a clear path throughout the development journey. There are many types of SDLC models, each with its unique strengths and weaknesses.
Spiral SDLC Model is a hybrid between iterative and sequential SDLC methods with an emphasis on risk control.. When working by the Spiral model, the team proceeds to the next software life cycle stage with design goals in mind and closes it after getting and implementing customer feedback.

There is no single "one-size-fits-all" system life cycle model that can provide specific guidance for all project situations. Figure 1, adapted from (Lawson 2010, ISO 2015, and ISO 2010), provides a generic life cycle model that forms a starting point for the most common versions of pre-specified, evolutionary, sequential, opportunistic ...
This paper proposes a cycle life model for lithium-ion batteries. The main objective of this work is to facilitate the electrical simulation of lithium-ion battery aging (due to cycling), and its impact on battery capacity and internal resistance. Most of the reported cycle life models are either: a) physics based, with parameters difficult to retrieve or b) semi-empirical, where the parameter ...
Brazil has emerged as the world's largest soybean producer and exporter in recent years. In the Brazilian Amazon Biome, the state of Pará has become a new agricultural frontier over the last two decades due to a significant increase in soybean cultivation throughout its territory. However, it is essential to understand the associated effects on the environment at …

The plots help in formulating a suitable mathematical model from failure data and provide information about failure rate. Also, inconsistent and incomplete data can be analyzed by this method [6,7,8]. In this study, TTT-plot is used to analyze rate of failures of crusher and its components considering time between successive failures (TBFs).
Factors influencing the Product Life Cycle. Regardless of whether the basic PLC model or the BCG matrix is used: The length of the product life cycle varies from product to product. Companies can influence the product life cycle through clever pricing, branding campaigns, and after-sales activities. But it's not all driven by internal factors.
