Summary: We propose a computational model of the quadruple helix innovation ecosystem as a cause of disruptive innovation. This model combines quantum computation and ecosystem dynamics to explain the process of disruptive innovation in the ecosystem. Using a quantum perspective, we show how the subtle splitting of capital accumulation stimulates factors such as capital, technology, and labor to transition from old status to new disruptive industries. This process occurs after the market symmetry breaking.

Summary: Climate change, energy transition needs, and the current energy crisis have led cities to implement significant changes in public energy supply. This paper aims to identify the conditions for sustainable energy provision and use, focusing on the role of citizens in a quadruple helix context. Citizen participation is considered crucial for successful local or district energy policies in urban areas, but it requires scientific and digital support based on evidence-based knowledge. The paper explores citizen engagement and knowledge base for drastic energy transitions in cities, using the diabolo model and proposing the use of digital tools as an interface between citizens and municipal policy. The empirical illustration of this approach is demonstrated through a case study of local energy policy in Rotterdam.

Summary: This study investigates an energy-efficient capacity control method for a cascade heat pump by adopting variable speed compressors to match the rated capacity of the heat pump at varying indoor and outdoor water temperatures. The results show that the COP of the heat pump is higher in the simultaneous control of the LT and HT compressor speeds and HT compressor speed control compared to LT compressor speed control. However, the control strategies have no significant difference in COP at varying indoor water temperatures. The study recommends using variable speed compressors at the high-temperature side and constant speed compressors at the low-temperature side for efficient and cost-effective capacity control of cascade heat pumps.

Summary: This study aims to develop a hybrid energy storage system (HESS) comprising battery and supercapacitor cells for a commercial Hybrid Electric Vehicle model (Hyundai Sonata) and evaluate its impact on battery health and vehicle performance. Different configurations of the energy storage devices are discussed, with a semi-active configuration used in simulations and testing. The addition of the supercapacitor stabilizes the battery's working status, reducing peak current and improving battery state of charge and temperature. However, there is a slight increase in fuel consumption due to losses in the supercapacitor system. A parametric study suggests that using 2 supercapacitor modules provides optimal results for battery behavior.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.
