Verdaasdonk, B.W. (author), Koopman, H.F.J.M. (author), Van der Helm, F.C.T. (author)Like human walking, passive dynamic walking—i.e. walking down a slope with no actuation except gravity—is energy efficient by exploiting the natural dynamics. In the animal world, neural oscillators termed central pattern generators (CPGs) provide the basic rhythm for muscular activity in locomotion. We present a CPG model, which automatically...journal article 2009

Visser, Mirjam (author), Schoormans, J.P.L. (author)To reduce energy consumption of households, many appliances contain eco-settings, which when used, reduce energy consumption. However, the effectivity of the eco-settings in reducing energy consumption is hardly tested. Other design for sustainable behaviour strategies like coercion and feedback might be more effective. To test the...journal article 2023

Qiu, Peng (author), Nunes, Breno (author), Vaidya, Kirit (author), van de Kaa, G. (author), Greeven, Mark (author)This paper investigates the energy service companies (ESCOs) in China from the perspective of technological capability (TC) development. The conventional capability development model of manufacturing in emerging economies has been adapted to examine the four dimensions of TC (investment, production, linkage and innovation) through a qualitative...journal article 2021

Graamans, L.J.A. (author), Tenpierik, M.J. (author), van den Dobbelsteen, A.A.J.F. (author), Stanghellini, Cecilia (author)The increase in global food demand has led to the introduction of new food production systems. One key example is the plant factory. Plant factories face the same challenge as many high-tech building functions: high energy demands resulting from high internal heat loads. In this study we investigate how this energy demand can be reduced...journal article 2020

Michael, M. (author), Overend, M. (author)Glazing is a critical buildings element as it is the most vulnerable envelope part to heat gain and heat loss accounting for around 50% of a building's energy consumption. However, conventional glazing technologies have relatively low-performance characteristics which cause significant heat losses during winter and undesired heat gain in...journal article 2021

Dimian, Alexandre C. (author), Kiss, A.A. (author)Acetic acid is an essential chemical used in the production of many chemical products. Using methanol as bio-building block, the acetic acid produced may be incorporated in bio-based products. This study deals with enhancing the efficiency of separations in a process using a homogeneous catalyst, which is the most applied today industrially....journal article 2021

(author), Mijatović, Ivan (author), Kržišnik, Davor (author), Humar, Miha (author), Brdjanovic, Damir (author)Thermal drying is an effective sludge treatment method for dealing with large volumes of sludge. Microwave (MW) technology has been proposed as an effective and efficient technology for sludge drying. The physical-chemical properties of the sludge depend both on the origin of the sludge, as well as on the treatment process at which the sludge...journal article 2022

Bianchi, S. (author), Ciurlanti, J. (author), Overend, M. (author), Pampanin, Stefano (author)Structural safety and environmental sustainability are major factors in investment decisions for building systems, but are rarely considered simultaneously. Recent research efforts have redressed this by developing assessment methodologies and technical solutions for integrated energy efficiency and seismic performance. These studies are...journal article 2022
