(author), van Gastel, Mark (author), Hendriks, B.H.W. (author), Ruers, Theo J.M. (author)Introduction: Anastomotic leakage after gastrointestinal surgery has a high impact on patient's quality of life and its origin is associated with inadequate perfusion. Imaging photoplethysmography (iPPG) is a noninvasive imaging technique that measures blood-volume changes in the microvascular tissue bed and detects changes in tissue...journal article 2023

Li, Wenting (author), Wang, Ping (author), Liang, K. (author)Password-only authentication is one of the most popular secure mechanisms for real-world online applications. But it easily suffers from a practical threat - password leakage, incurred by external and internal attackers. The external attacker may compromise the password file stored on the authentication server, and the insider may...journal article 2023

van Kuik, Nout (author)The large intestines, or colon, is the last part of the digestive tract before the rectum. Colorectal cancer is one of the main reasons that patients need a colon resection. A colon resection is a surgery in which the malignant part of the colon is removed. After removal of the tumor, the two ends of the colon need to be reattached, also called...master thesis 2022

Haschenburger, A.I. (author)Composites are increasingly used in the aerospace industry due to their lightweight potential and flexible design options. The most widespread manufacturing process for large components made of fibre composites is still the open mould process. In this process, a composite component is placed on a mould and hermetically sealed with a vacuum bag...doctoral thesis 2022

JACOB, JOSEPH (author)Many immersed tunnels have already reached or are about to reach the halfway point of their intended lifespan of 100 years. Around this time, several structural problems were noticed during inspection which have led to performance deterioration and durability issues of the tunnel. Often large- scale maintenance was required to meet the design...master thesis 2022

Patil, Ashutosh (author)With the increasing growth and penetration of power electronic devices in the power system, it is essential to understand the behaviour of insulation materials and systems under the varied signals that are produced with power electronic systems. These signals could be square pulses, sinusoidal or even superimposed. The high-frequency sinusoidal...master thesis 2022

Lambregts, Steven (author)Searchable Symmetric Encryption (SSE) schemes provide secure search over encrypted databases while allowing admitted information leakages. Generally, the leakages can be categorized into access, search, and volume pattern. In most existing Searchable Encryption (SE) schemes, these leakages are caused by practical designs but are considered an...master thesis 2022

Wu, Ran (author), Ma, Tao (author), Schröder, E. (author)International trade and emission offshoring can reduce a country's domestic carbon dioxide emissions, helping it to reach emission reduction targets set under the prevailing territorial climate policy frameworks. We ask what is the net contribution of trade to national production-based emissions. Existing metrics (consumption-based emissions and...journal article 2022

Battistel, F. (author)Computers are used all over the place to perform tasks ranging from sending an email to running some complicated numerical simulation. That is brilliant of course, because computers enable us to solve a lot of problems in the world in this way. At the same time, for some of those problems, not even powerful supercomputers are enough to get the...doctoral thesis 2022

Darwili, A.G. (author), Schröder, E. (author)We propose a new method for standardizing the production technology at the world average level and derive interpretations for the resulting carbon emission concepts. The technology-adjusted emission balance measures net weak carbon leakage defined as the difference between the foreign emissions avoided by exports and the foreign emissions...journal article 2022

Stegeman, B. (author), Hoffmann, Rob (author), Hopman, Victor (author), Langeveld, J.G. (author), Clemens-Meyer, Franҫois (author)The main application of the mobile geo-electrical measurement is the detection of the presence and determining the location of leakage in sewer systems. To do so, this method relies on the increase in the measured electrical current between an electrode inside and an electrode outside the sewer system. To use this technique for the...journal article 2022

Turan, Deniz (author), Poulis, J.A. (author)Glass bottles having a metal closure are preferred for oxygen sensitive beverages e.g. beer. Using thinner closure which comprise polyvinyl chloride-free component is more sustainable. However, protecting the sealing performance as a result of metal closure thickness reduction is challenging. Here we show the relation between the leakage in...journal article 2022

Someya, T. (author), Van Hoek, Vincent (author), Angevare, J. (author), Pan, S. (author), Makinwa, K.A.A. (author)This letter describes an NPN-based temperature sensor that achieves a 1-point trimmed inaccuracy of ±0.15 °C (3σ) from -15 to 85 °C while dissipating only 210 nW. It uses a dual-mode frontend to roughly halve the power consumption of conventional frontends. First, two NPNs are used to generate a well-defined PTAT bias current, then this...journal article 2022
