On The Coherence Time of Fiber-Based Distributed Antenna Systems

The possibility of using radio over fiber (RoF) analog transmissions to characterize the wireless propagation channel of distributed antenna systems is investigated. In particular, the coherence time of kilometer-long, fiber-based networks is analyzed. Joint measurements of the phase noise of parallel links to the same site (intra-site) and to different sites (inter-site) in such a network are pre

Energy/reliability trade-offs in fault-tolerant event-triggered distributed embedded systems

This paper presents an approach to the synthesis of low-power fault-tolerant hard real-time applications mapped on distributed heterogeneous embedded systems. Our synthesis approach decides the mapping of tasks to processing elements, as well as the voltage and frequency levels for executing each task, such that transient faults are tolerated, the timing constraints of the application are satisfie

Benevolent technotopias and hitherto unimaginable meats: Tracing the promises of in vitro meat

Today, in vitro (Latin: in glass) meat researchers strive to overhaul meat production technologies by producing meat outside animal bodies, primarily by culturing cells. In the process, meat should become healthier, more environmentally friendly and kinder to animals. In this article, I scrutinize (and problematize) this promissory discourse by examining the world that proponents envision alongsidToday, in vitro (Latin: in glass) meat researchers strive to overhaul meat production technologies by producing meat outside animal bodies, primarily by culturing cells.

Application-Set Driven Exploration for Custom Processor Architectures

Custom architectures are often adopted as more efficient alternatives to general purpose processors in terms of performance and power. However, the design of such architectures requires experts both in hardware and the application domain. In this paper we propose a method for speeding up the design space exploration. Our method, based on Pareto points, identifies sets of solutions in terms of scal

Human Trafficking and Slavery Reconsidered : Conceptual Limits and States' Positive Obligations in European Law

By reconsidering the international law definitions of human trafficking, slavery, servitude and forced labour, the book demonstrates that in embracing the human trafficking legal framework the international community side-lined the human rights commitments against slavery, servitude and forced labour that in many respects provide better protection for abused migrants. This development urgently req

Urban Radio Access Networks

The increase in demand for high-data rates on the move in the complex urbanenvironment requires either the allocation of new spectrum such as availablecontiguous spectrum in the mm-wave band or the use of novel configurationssuch as the application of massive multiple-input multiple-output (MIMO)technology. To enable the design of efficient wireless networks, an understandingof the propagation phe

Types of Trauma in Adolescence and Their Relation to Dissociation: A Mixed-Methods Study

Objective: To study adolescent traumatization and the impact of various types of trauma on dissociative experiences in a sample of 239 Swedish youngsters, 13 to 20 years of age, with diverse socioeconomic and migration backgrounds. We also evaluated whether the type of worst lifetime trauma was associated with higher rates of dissociation.Method: Quantitative and qualitative data on posttraumatic

Value creation character and value assessment responsibility

Value-based pricing is by many companies as well as in academia perceived as the preferred pricing model. The pricing literature includes a long-standing debate on pricing authority and centralized pricing authority can be associated with value-based pricing strategies. A critical success factor for value-based pricing is customer value assessment, and many companies have experienced challenges in

Engaging Students in Homework Assignments and Self-Study: A Study Case

This paper discusses teaching and learning activities (TLA) that forter students' commitment to homework and self-study. The discussion is illustrated with an exercise class, part of the International Master Programme in Wireless Communications at Lund University. The TLAs favored do not only look after the cognitive state and learning style preferences of the students, but they also take into accThis paper discusses teaching and learning activities (TLAs) that foster students’ commitment to homework and self-study.

Culinary tastes, social inequalities, and ecology in Cochabamba, Bolivia

Fried chicken or a vegetarian lunch? Dried llama meat or filet mignon? The cuisine in the “culinary capital of Bolivia”, the city of Cochabamba, is very diverse. Ethnographic research carried out by the author shows that the diet of the “Cochabambinos” is intimately linked to social status and social power struggles. In this paper, the author uses Bourdieu’s notion of the “field” in order to analy

Doubling the spectrum of time-domain induced polarization by harmonic de-noising, drift correction, spike removal, tapered gating, and data uncertainty estimation

The extraction of spectral information in the inversion process of time-domain (TD) induced polarization (IP) data is changing the use of the TDIP method. Data interpretation is evolving from a qualitative description of the subsurface, able only to discriminate the presence of contrasts in chargeability parameters, towards a quantitative analysis of the investigated media, which allows for detail

Optimization of time domain induced polarization data acquisition and spectral information content

The need for detailed subsurface information is increasing due to city expansion and infill projects as well as subsurface construction projects. One common method for acquiring this geo-information is the direct current resistivity and time domain induced polarization method (DCIP) that measures the electrical resistivity and chargeability of the subsurface.
