Mazza, F. (author)The present dissertation covers the development of ultrabroadband femtosecond/picosecond coherent Raman spectroscopy (CRS) to measure temperature and species concentrations in gas-phase chemically reacting flows.<br/>Since its first demonstration in 1965, CRS has been vastly employed as a non-linear optical spectroscopic technique to quantify...doctoral thesis 2023

Groet, Philip (author)With the rise of the new interconnect standards CXL and previously OpenCAPI, has come a great deal of possibilities to step away from the classical approach where CPUs are in charge of moving data between external devices and local memory. Specifically, OpenCAPI allows for attached devices to directly interface with the host memory bus in a near...master thesis 2023

Telang, Pankaj R. (author), Singh, Munindar P. (author), Yorke-Smith, N. (author)Social commitments are recognized as an abstraction that enables flexible coordination between autonomous agents. We make these contributions. First, we introduce and formalize a concept of a maintenance commitment, a kind of social commitment characterized by a maintenance condition whose truthhood an agent commits to maintain. This concept...journal article 2023

Goens, Andrés (author), Chakraborty, S.S. (author), Sarkar, Susmit (author), Agarwal, Sukarn (author), Oswald, Nicolai (author), Nagarajan, Vijay (author)Today's mobile, desktop, and server processors are heterogeneous, consisting not only of CPUs but also GPUs and other accelerators. Such heterogeneous processors are starting to expose a shared memory interface across these devices.Given that each of these individual devices typically supports a distinct instruction set architecture and a...journal article 2023

Dependence and risk spillovers among clean cryptocurrencies prices and media environmental attentionNdubuisi, G.O. (author), Urom, Christian (author)This paper examines the relationships among cryptocurrency environmental attention and clean cryptocurrencies prices using Time-Varying Parameter Vector Auto-Regression (TVP-VAR) and wavelets techniques. Results show strong connectedness among these variables, implying that the prices of clean cryptocurrencies are influenced by attention on...journal article 2023

Masoumi, H. (author), Verhaegen, M.H.G. (author), Myers, N.J. (author)Orthogonal matching pursuit (OMP) is a widely used greedy algorithm for sparse signal recovery in compressed sensing (CS). Prior work on OMP, however, has only provided reconstruction guarantees under the assumption that the columns of the CS matrix have equal norms, which is unrealistic in many practical CS applications due to hardware...conference paper 2023

Nazeer, Mubbashar (author), Ali, W. (author), Hussain, Farooq (author)Problem statement: The study offers theoretical formulations for high-viscosity particulate flows in inclined reservoirs, taking into account the presence of homogeneous spheroidal particles of various types to produce discrete two-phase suspensions. Purpose: The primary objective of this analytical and comparative study is to identify the most...journal article 2023

John, Tumaini Wambua (author), Sušnik, Janez (author), Masia, Sara (author), Jewitt, G.P.W. (author)The intricate connections between water, land, food, energy, and climate change require a multicentric approach to evaluating the trade-offs and synergies needed to achieve sustainable development. For example, the amount of water required in irrigated agriculture, consumptive water uses, and hydro-power production can potentially lead to...journal article 2023

Kuttippurath, Vivek (author), Slijkhuis, Nuria (author), Liu, Shengnan (author), van Soest, G. (author)Significance: Spectroscopic analysis of optical coherence tomography (OCT) data can yield added information about the sample's chemical composition, along with high-resolution images. Typical commercial OCT systems operate at wavelengths that may not be optimal for identifying lipid-containing samples based on absorption features. Aim: The...journal article 2023

Bucci Ancapi, F.E. (author)As European governments adopt new circular built environment policies to cope with the socio-ecological crisis, the need for evaluating such policies gains in urgency. Ex post evaluation is, however, difficult as these policies have not been in place long enough to have had significant effects. Nonetheless, ex ante policy evaluation may be...journal article 2023

Huisman, Kees Theo (author), Franco-Clavijo, Natalia (author), Vrouwenvelder, J.S. (author), Blankert, Bastiaan (author)In this study, a biofouling index based on the relative pressure drop is presented to quantitatively evaluate the amount of fouling in spacer-filled membrane filtration channels. The biofouling index was defined as the inverse of the time to reach a relative pressure drop of 100% and can be interpreted as a fouling rate or cleaning frequency....journal article 2023

Conroy, Philip (author), van Diepen, S.A.N. (author), van Leijen, F.J. (author), Hanssen, R.F. (author)We introduce the term loss-of-lock to describe a specific form of coherence loss that results in the breakage of a synthetic aperture radar interferometric (InSAR) time series. Loss-of-lock creates a specific pattern in the coherence matrix of a multilooked distributed scatterer (DS) by which it may be detected. Along with identification, we...journal article 2023
