Multidimensional evaluation of tenants’ temporal relocation during a renovation: A comparison between two case studies from Sweden

This research focuses on the tenants’ temporal relocation or stay in the home during renovation works and the property owners’ possibility to refurbish with intense and global interventions. The study compares two renovation strategies applied in two residential neighbourhoods in Gothenburg, Sweden, built between the 1950s and 1960s. In one neighbourhood, the tenants stayed in their homes during the renovation works, and in the other neighbourhood, the tenants were relocated to other buildings for over six months. Retrofitting interventions, investment costs, rent increase, time periods and the constructive processes are considered for each renovation strategy, as well as the impressions of the tenants and property owner entities in each neighbourhood were collected. The results compare, through a report on the affordability and effectiveness, the pros and cons of a relocation or non-relocation strategy. This research offers a real and experimental comparison that reach to political, architectural, social and economic conclusions to facilitate the decision-making regarding the tenants’ temporal relocation. Finally, it is also highlighted the need to involve the tenants in the design of effective renovation proposals

A framework for automatically generating optimized digital designs from C-language loops

Reconfigurable computing has the potential for providing significant performance increases to a number of computing applications. However, realizing these benefits requires digital design experience and knowledge of hardware description languages (HDLs). While a number of tools have focused on translation of high-level languages (HLLs) to HDLs, the tools do not always create optimized digital designs that are competitive with hand-coded solutions. This work describes an automatic optimization in the C-to-HDL transformation that reorganizes operations between pipeline stages in order to reduce critical path lengths. The effects of this optimization are examined on the MD5, SHA-1, and Smith-Waterman algorithms. Results show that the optimization results in performance gains of 13%-37% and that the automatically-generated implementations perform comparably to hand-coded implementations

Energy, economic and environmental modelling for supporting strategic local planning

This study investigates the use of an evaluation model able to estimate the possibilities of reducing energy consumption and emissions of the building sector exploiting renewable energy sources. Specific attention is given to the use of ground source heat pumps in the urban context, proposing an ex-ante evaluation of different scenarios to identify the most balanced one in terms of energy, economic and environmental effects. The model is applied to a case study in Northern Italy to show how it can be used to support local administrations in energy urban planning, fitting economically and environmentally sustainable technologies. Moreover, it defines new boundaries in which the energy and environmental analyses should be carried out (spatial relocation), and the time span over which impacts have to be evaluated (temporal relocation)

The voices of vulnerable tenants in renovation

This paper focuses on the intersection between agendas for housing renovation and social politics for ageing-in-place and social integration of people with psycologial disabilities. The aim is to understand how elderly tenants and people on a longer sick leave are affected by a renovation. In a sample of 79 interviews, 34 tenants decided to permanently relocate as a results of a renovation. When the renovation is a driver for permanent relocation, tenants do so to avoid disturbances and temporal evacuation. If the home is subjet to a comprehensive or deep renovation, rent increases is another reinforcing factor to relocate. While tenants that move prior to a renovation worry about how the renovation will affect their daily life and their economy, tenants that move after the renovation do so because they are dissatisfied with the results of the renovation. The findings calls for awareness for how housing renovation will affect vulnerable tenants and highlights the need for the design or appropriate communication strategies

Video Game Navigation: A Classification System for Navigational Acts

Navigation in video games has been a vastly neglected topic in game studies. In this paper a classification system for navigational acts has been developed through theoretical work as well as the analysis of multiple games. The result is an exclusive five-step classification system. Moreover, the development showed that navigational acts are highly dependent on the environment in which they occur. The system is a first step towards a deeper understanding of how the player navigates the gameworld, instead of what she navigates

Time, tide and narrative: adapting chronology in Master and Commander: The Far Side of the World

This paper is concerned with the 2003 film Master and Commander: The Far Side of the World, and with the book – or more accurately – books from which it is adapted. The film’s source material comes from novelist Patrick O’Brian who, between 1969 and his death in 2000, wrote 20 completed novels, plus one unfinished work. While no single text manifests a glaring temporal anomaly, taken as a whole it is apparent that numerous factors including the age of characters, aspects of their backstory, and especially the cumulative duration of several epic sea journeys do not cohere. It is not the object of this paper to treat this distortion as a failure. Rather, it is to focus on how the single screen adaptation engages with this aspect of its literary predecessors

Trophic factor BDNF inhibits GABAergic signaling by facilitating dendritic enrichment of SUMO E3 ligase PIAS3 and altering gephyrin scaffold

Posttranslational addition of a small ubiquitin-like modifier (SUMO) moiety (SUMOylation) has been implicated in pathologies such as brain ischemia, diabetic peripheral neuropathy, and neurodegeneration. However, nuclear enrichment of SUMO pathway proteins has made it difficult to ascertain how ion channels, proteins that are typically localized to and function at the plasma membrane, and mitochondria are SUMOylated. Here, we report that the trophic factor, brain-derived neurotrophic factor (BDNF) regulates SUMO proteins both spatially and temporally in neurons. We show that BDNF signaling via the receptor tropomyosin-related kinase B facilitates nuclear exodus of SUMO proteins and subsequent enrichment within dendrites. Of the various SUMO E3 ligases, we found that PIAS-3 dendrite enrichment in response to BDNF signaling specifically modulates subsequent ERK1/2 kinase pathway signaling. In addition, we found the PIAS-3 RING and Ser/Thr domains, albeit in opposing manners, functionally inhibit GABA-mediated inhibition. Finally, using oxygen-glucose deprivation as an in vitro model for ischemia, we show that BDNF-tropomyosin-related kinase B signaling negatively impairs clustering of the main scaffolding protein at GABAergic postsynapse, gephyrin, whereby reducing GABAergic neurotransmission postischemia. SUMOylation-defective gephyrin K148R/K724R mutant transgene expression reversed these ischemia-induced changes in gephyrin cluster density. Taken together, these data suggest that BDNF signaling facilitates the temporal relocation of nuclear-enriched SUMO proteins to dendrites to influence postsynaptic protein SUMOylation

What are typical levels of housing renovation? A typology based on Swedish public strategies

The gap between energy policy and potential energy savings through renovation, and what is carried out in practice has been in focus of previous research. Various influencing factors such as economy, organisation, and social relations versus tenants has been studied to design guidelines to bridge this gap. There is a lack of empirical studies of how renovation is planned, and what factors will influence the renovation measures that are implemented. This paper takes the starting point in 42 on-going and planned housing renovation projects 2018 - 2021 carried out by three municipal housing companies in one major Swedish metropolitan area. Based on the character of these, three main types of housing renovation are defined. The most current type of renovation is bathroom and piping while climate envelope renovation and deep renovation are less common. Energy saving is decoupled from renovation activities which will have implications for implementation of policy for energy efficient renovation
