Lean Transformation and Implementation
The application of Lean Manufacturing (LM) in both the service and manufacturing industries has demonstrated improvements in organizational performance. Other benefits obtained from LM implementation include improved flexibility, profitability, and efficiency; continuous improvement in processes; reduced production costs; improved customer satisfaction; enhanced just-in-time production (JIT); ergonomic improvements for employees; and increased product reliability. This success implies that Lean is universal and is not a fad that will pass away. Furthermore, recent research shows that LM is a base upon which new technologies such as Industry 4.0 can be built.

Library Catalog
A library catalog or library catalogue is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations. A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library. The card catalog was a familiar sight to library users for generations, but it has been effectively replaced by the online public access catalog (OPAC). Some still refer to the online catalog as a "card catalog". Some libraries with OPAC access still have card catalogs on site, but these are now strictly a secondary resource and are seldom updated. Many libraries that retain their physical card catalog will post a sign advising the last year that the card catalog was updated. Some libraries have eliminated their card catalog in favour of the OPAC for the purpose of saving space for other use, such as additional shelving. The largest library catalog in the world is the WorldCat.org union catalog managed by the non-profit library cooperative OCLC, based in Dublin, Ohio. In January 2016, WorldCat.org had over 360,000,000 catalog records and over 2 billion library holdings.

Life Cycle Thinking for a Circular Bioeconomy
The circular bioeconomy (CBE) is an increasingly popular method used to add value to bio-based products. However, these products entail impacts on sustainability that can be assessed by life cycle thinking (LCT). LCT is an approach to assess the impacts of products throughout their life cycles by using different tools, namely: (environmental) life cycle assessment (LCA), life cycle costing (LCC), social life cycle assessment (SLCA) and life cycle sustainability assessment (LCSA), which is a combination of the three and aims to assess the impacts of all of the three dimensions of sustainability.

Live Cell Imaging
Live cell imaging is the study of living cells using time-lapse microscopy. It is used by scientists to obtain a better understanding of biological function through the study of cellular dynamics. Live cell imaging was pioneered in first decade of the 21th century. One of the first time-lapse microcinematographic films of cells ever made was made by Julius Ries, showing the fertilization and development of the sea urchin egg. Since then, several microscopy methods have been developed which allow researchers to study living cells in greater detail with less effort. A newer type of imaging utilizing quantum dots have been used as they are shown to be more stable. The development of holotomographic microscopy has disregarded phototoxicity and other staining-derived disadvantages by implementing digital staining based on cells’ refractive index.

Machine Learning for RC monitoring
The reciprocating compressor (RC) is a key piece of equipment in petroleum and chemical industries. If the RC does not operate in the rated efficiency, it will lead to great economic loss to the company. Sometimes RCs are used to compress inflammable and explosive gases working under high pressures and temperatures, such as hydrogen, ethylene, and natural gas, which would threat human life once the machine malfunctions. Furthermore, due to the intricate structure of the compressor, a large amount of wearing parts, and the complicated interactional relationship between moving parts of the compressor, it is essential to monitor the compressor operating condition and detect failures of RCs accurately and in a timely manner. Operating condition detection and fault diagnosis are very important for reliable operation of reciprocating compressors. Machine learning is one of the most powerful tools in this field.

Machine-Learning Based Methods for PV
This entry presents the state of the art ML models applied in solar energy’s forecasting field i.e., for solar irradiance and power production forecasting (both point and interval or probabilistic forecasting), electricity price forecasting and energy demand forecasting. Other applications of ML into the photovoltaic (PV) field taken into account are the modelling of PV modules, PV design parameter extraction, tracking the maximum power point (MPP), PV systems efficiency optimization, PV/Thermal (PV/T) and Concentrating PV (CPV) system design parameters’ optimization and efficiency improvement, anomaly detection and energy management of PV’s storage systems. While many review papers already exist in this regard, they are usually focused only on one specific topic, while in this paper are gathered all the most relevant applications of ML for solar systems in many different fields. It gives an overview of the most recent and promising applications of machine learning used in the field of photovoltaic systems.

Machine-Vision-Based Leather Surface Defect Inspection
Machine-vision-based surface defect inspection is one of the key technologies to realize intelligent manufacturing. Leather products are regarded as the most traded products all over the world. Automatic detection, location, and recognition of leather surface defects are very important for the intelligent manufacturing of leather products, and are challenging but noteworthy tasks. Machine-learning-based defect inspection methods include three main links in industrial applications: data annotation, model training, and model inference. Real-time performance in real industrial applications focuses more on this part of model inference.

Magnetic Fields in Food Processing
Magnetic fields (MF) are increasingly being applied in food processing to preserve food quality. They can be static (SMF), oscillating (OMF) or pulsed (PMF) depending on the type of equipment. The food characteristics can be influenced by several configurations of the applied magnetic field as its flux density, frequency, polarity, and exposure time. Several mechanisms have been proposed to explain the effects of magnetic fields on foods. Some of them propose interactions at the subatomic particle level that show quantum behavior, such as the radical pair and cyclotron resonance mechanisms. Other proposals are at the level of DNA, compounds, subcellular organelles, and cells.  The interactions between food and magnetic fields are addressed in a general way in this work, highlighting the applications and action model

Maintenance Strategies in Industry
Maintaining equipment in good condition is an important issue in the production process. Appropriate service and maintenance contribute to a high level of availability and reduce production downtimes. On the other hand, in power plants, maintenance costs represent a significant financial expense. Therefore, it is essential to achieve acceptable production results while optimizing service costs.
