We present the development of an instantaneous multispectral imaging technique exploiting spatially modulated light. Each encoded excitation source produces an image with a predefined position in the Fourier domain, allowing them to be separated computationally.

Co-design of monolithically-integrated millimetre-wave front-ends and antennas is alleviated by accurate device models. In this paper, a novel transmission line model for slotcoupled dielectric resonator antennas is proposed and verified. It describes distributed interaction between the coupling-structure and the radiating dielectric body of the antenna. This model thereby provides a simplistic an

Today’s communities are characterized by migration, transnationalism, and participation in the global economy, and many also have long local histories of linguistic diversity. Empowering individuals in these contexts means fostering the ability to use and expand their existing linguistic repertoires so they can take advantage of the social and economic opportunities afforded by contemporary life.

In this paper, we consider precoder design for multiuser multiple-input-multiple-output (MIMO) Gaussian broadcast (BC) channels and propose a generalized zero-forcing (GZF) precoder based on successive dirty-paper coding (DPC), i.e., the GZF-DP precoder. The GZF-DP precoder is an extension of the GZF-DP precoder designed earlier for multi-input-single-output broadcast (MISO-BC) channels, and also

This report summarizes the work in practically determining how frequently used aerosol- and propane containers are affected at fire exposure from flammable liquids. The tested aerosol- and propane containers were chosen due to common appearance in ordinary grocery- and hardware stores. The tested aerosol containers had a volume range between 15- 400 ml and the propane containers were filled with 0

Purpose We validate the usefulness of laser-induced autofluorescence for the detection of bladder carcinoma. Materials and Methods We obtained and analyzed fluorescence spectra from 75 patients in whom bladder cancer was suspected. Tissue fluorescence was excited by a nitrogen laser using a quartz optical fiber placed in gentle contact with the area of interest. The laser-induced autofluorescence

The growing complexity of digital signal processing applications make a compelling case the use of high-level design and synthesis methodologies for the implementation on reconfigurable and embedded devices. Past research has shown that raising the level of abstraction of design stages does not necessarily gives penalties in terms of performance or resources. Dataflow programs provide behavioral d

Plastics are versatile, cheap and durable materials that are omnipresent in modern society. Since most of them are derived from crude oil and are not biodegradable, their production leads to the depletion of fossil fuels and the accumulation of enormous amounts of plastic waste that pollutes ecosystems worldwide. For this reason, the European Union and other organisations are investing in research

An underwater ERT survey was made along a planned road tunnel for The Stockholm Bypass Project (Förbifart Stockholm). The aim was to assess the ability to identify variations in the depth of the bottom sediments, as well as variations in rock quality and the possible presence of weak zones in the rock. Reference data from a seismic survey and geotechnical drilling was used for evaluation the resul

A novel electron deficient 4,6-bis(trifluoromethyl)-1,3-phenylene diphosphinite ligand 4 was developed and synthesized. Reaction of Ir precursors with ligand 4 gave chloro(hydride) pincer complex 5, which demonstrated a higher TON in alkane dehydrogenation reactions compared to similar phosphinite based pre-catalysts. The formation of cyclooctene (COE) and tert-butylethylene adducts of the 14e cat

Aims. Spectral lines of He-like ions are among the most prominent features in X-ray spectra from a large variety of astrophysical and high-temperature fusion plasmas. A reliable plasma modeling and interpretation of the spectra require a large amount of accurate atomic data related to various physical processes. In this paper, we focus on the electron-impact excitation (EIE) process. Methods. We a

A sociocultural perspective was utilized to explore if concept mapping using macroscopic, symbolic and submicroscopic aspects (often referred to as the ‘chemistry triplet’) can be used to promote development of expert knowledge in secondary school chemistry students by facilitating multilevel thinking. An additional aim was to explore the possibilities of using sociocultural theory to study the de

The breaching of planetary boundaries and excessive extraction of natural resources requires a revisited approach to consumption and production. The concept of sufficiency, which advocates meeting human needs within the planetary limits by curbing excessive consumption levels, is gaining increasing attention. Businesses are drivers of consumption, yet they have been largely overlooked as potential

This article critically examines the approach of technical experts, including engineers, natural scientists, architects, planners, and other practitioners, who are attempting to create more sustainable forms of economic development, environmental protection, and social equity. The authors identify four principal characteristics of expertise–ontological assumptions, epistemological approaches, powe

The osmotic pressure of dilute electrolyte solutions containing charged macro-ions as well as counterions can be computed directly from the particle distribution via the well-known cell model. Originally derived within the Poisson-Boltzmann mean-field approximation, the cell model considers a single macro-ion centered into a cell, together with counterions needed to neutralize the total cell charg

IoT networks are getting overcrowded following the vast increase in number of Internet-of-Things (IoT) devices and connections. Networks can be extended with more gateways, increasing the number of supported devices. However, as investigated in this work, massive MIMO has the potential to increase the number of simultaneous connections and moreover lower the energy expenditure of these devices. We
