Process and utility systems integration and optimisation for ultra-low energy milk powder production
(2017-04-26)
This study applies a Total Site Heat Integration approach in conjunction with a detailed process and utility model, to develop an innovative ultra-low energy milk powder plant design. The basis for the analysis is a state-of-the-art modern milk powder plant that requires 5265 MJ/tp of fuel and 210.5 kWh/tp (58.5 MJe/tp) of electricity. The model of the modern milk powder plant was validated against industrial data and changes to process and/or utility systems are targeted and implemented into the model to understand ...

Linking entrepreneurial orientation to firm performance in a post-socialist market context: the case of Hungary
(2016)
Entrepreneurial orientation provoked the interest of numerous scholars as well as political and administrative decision-makers. Both start-ups and already established corporate entities are increasingly persecuting new opportunities, products, and business models in order to establish superiority above their competitive environment. The tendencies evince an optimist impact of entrepreneurial orientation on business performance, namely on financial performance. Beyond the aforementioned relationship, there are impulses ...

Financial Access and Food Productivity Nexus: Evidence from Pakistan
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-12-26)
Food possesses a great importance in the lives of human beings as it provides energy and strength to the human body to think, grow and develop. The global population is increasing day by day, becoming even more difficult to manage food for every human being on earth. It is the responsibility of every state to provide food for its citizens. “Zero Hunger” is one of the major goals of the Sustainable Development Goals (SDGs’) which aims to eradicate hunger from world. Several causes of food insecurity are identified by ...

Total Site Utility Systems Optimisation for Milk Powder Production
(2016)
This study applies the Total Site Heat Integration method, in conjunction with a detailed process and utility model, to investigate three methods to increase the energy efficiency of the utility supply system for milk powder production. Sequentially explored opportunities are: (1) increasing boiler efficiency through condensing economisers, (2) waste heat recovery from the chiller unit, and (3) Combined Heat and Power (CHP) for electricity production. The basis for the analysis is the anticipated future milk powder ...

Automatic Time Series Segmentation as the Basis for Unsupervised, Non-Intrusive Load Monitoring of Machine Tools
(2019)
Detailed energy monitoring and benchmarking at the individual component level is necessary to increase energy efficiency in complex production systems. Non-intrusive load monitoring (NILM) provides an economical solution for operational state detection and load disaggregation without the need for large-scale use of fine-grained energy meters. Existing supervised NILM approaches require detailed training data including control information about individual devices. Unsupervised approaches, on the other hand, often ...

Numerical Two-Scale Simulations of Damage Evolution at Refractory Materials
(2014-02-25)
Fracture and damage processes on micro- and mesoscale are combined with macroscale simulations applying numerical multiscale approaches. Cracks and grain boundaries are reproduced in cell models that take account of transand intercrystalline crack growth. The global, in general thermomechanical boundary value problem is considered within a continuum mechanics framework. Two approaches are presented combining the scales. Simple processes on the smaller level are described in analytical models including the damage ...
