description: Background. Content management systems (CMS) provide default features that make it easy even for laypersons to create and maintain sophisticated websites [3]. But a CMS also poses a security risk. Not only can the CMS’s framework itself contain vulnerabilities. Also, there is a vast number of plugins and templates that may introduce vulnerabilities [3, 5]. We are looking for websites that are vulnerable to search engine Spam (SEO Spam) or Pharma Hacks, where an attacker deploys code on a website to redirect to fake web shops [11, 12]. The manipulation is not visible on the
genuine website, but the sites appear in the search engine results as shops selling illegal or banned drugs / medicines, luxurious brand-name clothing, or expensive appliances for cheap. Often, the malicious code is hidden within the CSS files of a website and cannot be easily found – even by skilled developers [11].

Aim. Since the problem is not easy to detect and only visible in a website’s search results, most website owners have to rely on vulnerability notifications by the security community to be informed about the manipulation. In trying to create suitable vulnerability notifications, with which we could inform the website owners about the security issues, we conducted 25 semi-structured interviews with affected website owners and discussed the perception of vulnerability notifications with them. To our knowledge, none of the experimental studies on vulnerability notifications [1, 4, 6–9, 13–21] have conducted qualitative interviews with affected website owners, to identify common themes and trust-promoting factors for a vulnerability notification. The motivation of our work was to answer the following research questions: (1) How did website owners perceive previous web vulnerability notifications? (2) What are suitable senders and communication channels that the website owners deem trustworthy? (3) What aspects should we consider in future notifications to be deemed trustworthy? Finally, by answering these questions, we aimed at designing a vulnerability notification that is suitable to informwebsite owners about the security issue on their website.

description: The statistical properties of the density map (DM) approach to counting microbiological objects on images are studied in detail. The DM is given by U$^2$-Net. Two statistical methods for deep neural networks are utilized: the bootstrap and the Monte Carlo (MC) dropout. The detailed analysis of the uncertainties for the DM predictions leads to a deeper understanding of the DM model's deficiencies. Based on our investigation, we propose a self-normalization module in the network. The improved network model, called \textit{Self-Normalized Density Map} (SNDM), can correct its output density map by itself to accurately predict the total number of objects in the image. The SNDM architecture outperforms the original model. Moreover, both statistical frameworks -- bootstrap and MC dropout -- have consistent statistical results for SNDM, which were not observed in the original model. The SNDM efficiency is comparable with the detector-base models, such as Faster and Cascade R-CNN detectors.

Under-balancing mechanical supply and exhaust ventilation systems with heat recovery – effects on energy use
Creators: name: Johansson, Dennis
name: Johansson, Dennis
Publisher: name: 8th Symposium on Building Physics in the Nordic Countries
Year: 2008

description: Mechanical supply and exhaust ventilation with heat recovery is usually slightly under-balanced. That means that the supply air flow rate is lower than the exhaust air flow rate. That is made in cold climates to prevent moist air from infiltrating the building construction parts. Usually, the exhaust air is more polluted so the exhaust filter pressure rises quicker than the supply filter pressure. The under-balanced ventilation therefore gives a margin to avoid over-pressure with time. If the ratio between supply and exhaust airflow rate is zero, the ventilation system can be understood as an exhaust only system. The under-balanced supply air flow affects the pressure difference between the inside and the outside of the house. This pressure difference in turn affects the sensitivity for infiltration due to buoyancy and wind. A higher under-pressure inside due to under-balance prevents air that comes in with the wind to pass through the building which means that the unintentional air leakage decreases. On the other hand, if the supply air flow is under-balanced, the available air flow for heat exchange in the heat recovery unit is decreased which means that the recovered heat decreases. This effect is dampened by the fact that the temperature efficiency related to the supply air of the heat recovery unit increases if the supply air flow is lowered. Still, the decreasing amount of recovered heat increases the need for heating the ventilation air. This study analyzed the effect of under-balanced supply air on the energy use. Theories were compared to simulations with actual wind data for Swedish climate. It was found that there is a minimum energy use for an optimal under balance ratio in some cases depending on the air tightness and nominal ventilation air flow rate.

description: We investigate the conditions that facilitate galactic-scale outflows using a sample of 155 typical star-forming galaxies at $z$~2 drawn from the MOSFIRE Deep Evolution Field (MOSDEF) survey. The sample includes deep rest-frame UV spectroscopy from the Keck Low-Resolution Imaging Spectrometer (LRIS), which provides spectral coverage of several low-ionisation interstellar (LIS) metal absorption lines and Ly$α$ emission. Outflow velocities are calculated from the centroids of the LIS absorption and/or Ly$α$ emission, as well as the highest-velocity component of the outflow from the blue wings of the LIS absorption lines. Outflow velocities are found to be marginally correlated or independent of galaxy properties, such as star-formation rate (SFR) and star-formation rate surface density ($Σ_{\rm SFR}$). Outflow velocity scales with SFR as a power-law with index 0.24, which suggests that the outflows may be primarily driven by mechanical energy generated by supernovae explosions, as opposed to radiation pressure acting on dusty material. On the other hand, outflow velocity and $Σ_{\rm SFR}$ are not significantly correlated, which may be due to the limited dynamic range of $Σ_{\rm SFR}$ probed by our sample. The relationship between outflow velocity and $Σ_{\rm SFR}$ normalised by stellar mass ($Σ_{\rm sSFR}$), as a proxy for gravitational potential, suggests that strong outflows (e.g., > 200 km s$^{-1}$) appear ubiquitous above a threshold of log($Σ_{\rm sSFR}/\rm{yr}^{-1}\ \rm{kpc}^{-2}$) ~ -11.3, and that above this threshold, outflow velocity uncouples from $Σ_{\rm sSFR}$. These results highlight the need for higher resolution spectroscopic data and spatially resolved imaging to test the driving mechanisms of outflows predicted by theory.

description: Ground slabs and basement walls are a unique part of building envelope in direct and constant contact with the subsoil stratum or the constructed fill layers. The coarse-grained fill or drainage layer beneath a slab forms an outmost segment of this envelope preventing free capillary or gravitationally waters from penetrating the adjoining structural elements. Thermal and moisture conditions in these layers form the boundary conditions of ground slabs as far as the building physics of the structure is concerned. Despite the undeniable necessity to know these boundary conditions, temperature and moisture content of fill and drainage layers have been almost an unknown factor in the design of ground slabs.
   The objective of this research was to determine the typical thermal, moisture and microbiological boundary conditions of slab-on-ground structures. According to the performed long-term field surveys, coarse-grained fill or drainage layers beneath slab-on-ground structures of heated buildings are warm and moist throughout the year. These conditions are favourable for the microbe growth, and according to the performed field survey, the microbe growth is indeed very common in fill layers. The fungal or bacteria growth in general was detected in 98 % of the test specimens taken beneath the ground slabs of heated buildings. The indicator species, either fungal or bacteria, were detected in 79 % of the specimens. Also the average concentration of the detected microbes was high. Yet, no moisture damage related to ground floors was ever detected or recorded in the case buildings. The high microbe concentration in the fill layer beneath ground slabs is not a sign of moisture damage, but a natural state of the moist and warm fill layer.

description: Using data from the Pantheon SN Ia compilation and the Sloan Digital Sky Survey (SDSS), we propose an estimator for weak lensing convergence incorporating positional and photometric data of foreground galaxies. The correlation between this and the Hubble diagram residuals of the supernovae has $3.6σ$ significance, and is consistent with weak lensing magnification due to dark matter halos centered on galaxies. We additionally constrain the properties of the galactic haloes, such as the mass-to-light ratio $Γ$ and radial profile of the halo matter density $ρ(r)$. We derive a new relationship for the additional r.m.s. scatter in magnitudes caused by lensing, finding $σ_{\rm lens} = (0.06 \pm 0.017) (d_{\rm C}(z)/ d_{\rm C}(z=1))^{3/2}$ where $d_{\rm C}(z)$ is the comoving distance to redshift $z$. Hence the scatter in apparent magnitudes due lensing will be of the same size as the intrinsic scatter of SN Ia by $z \sim 1.2$. We propose a modification of the distance modulus estimator for SN Ia to incorporate lensing, which can be easily calculated from observational data. We anticipate this will improve the accuracy of cosmological parameter estimation for high-redshift SN Ia data.

description: Two wall-testing protocols used for evaluating wall assemblies in the Canadian arctic were developed. The protocols were developed as part of a project to develop building envelope assemblies that are energy efficient and durable under extreme cold outdoor climates and indoor conditions typically found in these climes. The objective of the testing phase was to evaluate the hygrothermal performance of wall assemblies as well as providing input for hygrothermal simulations. The exterior test protocol was based on a representative arctic location selected on the basis of a climate characterization study carried out using Canadian locations. The protocol comprises four parameters: temperature, wind, atmospheric moisture, and solar irradiance. An accelerated test lasting six weeks was defined. Three seasons are represented; winter, spring, and summer. The interior protocol was based on data obtained from a survey of interior conditions of Canadian houses located in cold regions as part of the project. The interior protocol comprises two parameters temperature and interior moisture, and is intended to be used with the exterior protocol.

description: Pre-trial detention is a type of incarceration in which individuals arrested or imprisoned due to a criminal charge is detained, either in police custody or in a prison, but have not yet been tried and sentenced. The main objective of this study is to describe the challenges suspects are facing during pre-trial detention in Bishoftu City. The study employs both secondary and primary data. Books, journals, and laws are used as secondary data. The primary data is obtained using a qualitative research approach. Since the study is targeted at describing the experiences of the detainees, it employs a phenomenological study. In-depth interviews focus group discussions and observations are employed. Participants are sampled purposively, and the sample size is determined through data saturation. Accordingly, thirteen pre-trial detainees, four investigative officers, three public prosecutors, and two criminal bench judges are interviewed; and detention centers are observed. Prolonged detention without securing bail right is one of the challenges suspects are encountering. Some of the study's findings include overcrowding, a lack of food service, a lack of sanitation, a lack of medical services, and the government's failure to properly implement bail rights. The study reveals the presence of arbitrary detentions contrary to the statutes governing detention. The study also depicts a lack of coordination among actors of the criminal justice system in ensuring the rights of detainees. As can be deduced from the findings, the rights of detained people are being violated during arrest as well as incarceration. Thus, greater effort must be placed on ensuring that pretrial detention is used as a needs during detention. Actors of the criminal justice system should work jointly in ensuring the rights of citizens.

description: Wireless millimeter-scale origami robots that can locomote in narrow spaces and morph their shapes have recently been explored with great potential for biomedical applications. Existing millimeter-scale origami devices usually require separate geometrical components for locomotion and functions, which increases the complexity of the robotic systems and their operation upon limited locomotion modes. Additionally, none of them can achieve both on-ground and in-water locomotion. Here we report a magnetically actuated amphibious origami millirobot that integrates capabilities of spinning-enabled multimodal locomotion, controlled delivery of liquid medicine, and cargo transportation with wireless operation. This millirobot takes full advantage of the geometrical features and folding/unfolding capability of Kresling origami, a triangulated hollow cylinder, to fulfill multifunction: its geometrical features are exploited for generating omnidirectional locomotion in various working environments, including on unstructured ground, in liquids, and at air-liquid interfaces through rolling, flipping, and spinning-induced propulsion; the folding/unfolding is utilized as a pumping mechanism for integrated multifunctionality such as controlled delivery of liquid medicine; furthermore, the spinning motion provides a sucking mechanism for targeted solid cargo transportation. This origami millirobot breaks the conventional way of utilizing origami folding only for shape reconfiguration and integrates multiple functions in one simple body. We anticipate the reported magnetic amphibious origami millirobots have the potential to serve as minimally invasive devices for biomedical diagnoses and treatments.

description: There has been a dramatic revolution in the conduct of science in recent years, primarily triggered by the digital revolution. Online science, collaboratories, data-intensive science, digital libraries, and scientific social networks have changed the character of science practice. Despite this revolution in how scientists do their work, there has been very little change in standard science courses and curricula to match this reality. Numerous professional society working groups, national academies committees, and national agency blue ribbon panels have produced reports that call for dramatic changes in science education at all levels. In one case, a panel of experts produced the special report "Transform Science: Computational Education for Scientists" [1]; and in another case, a landmark journal article on "Computational Thinking" is transforming numerous NSF research programs and proposal requirements [2]. The proposed interactive presentation session for ITL'2010 will present some of the recommendations from the national study reports, and will open a dialogue among Mason faculty on how we can transform our own science courses and curricula to match the current realities of scientific research in the digital age. Such a transformation will better prepare our students for the world into which they will be embarking, and will aid in the development of the computationally skilled and data-savvy workforce required in the 21st century workplace. These programs will havethe additional benefit of attracting the best and the brightest students to Mason when they see this transformative science being taught here, and will prepare them in an exemplary manner for the next steps in their careers. Additional benefits include the focus on problem-based learning, the natural inclusion of undergraduates in the scientific scholarly community, and the attraction of diverse student populations into science (through their pre-existing familiarity with information technology tools) [3].

description: Although vacuum insulation panels (VIPs) have widely been used in refrigerators and transport containers for a long time, they have only recently been discovered by the building sector. A vacuum insulation panel is a thermal insulator consisting of an open-celled core material, which is after evacuation tightly sealed into a high barrier laminate to maintain the state of vacuum. In this state of vacuum, the ideal or centre-of-panel thermal conductivity of a VIP is as low as about 0.004 W/m/K. As a consequence, vacuum insulation panels combine high thermal performance with limited construction thickness. Integrated into building panels, however, a thermal bridge effect occurs at the panel’s edge due to the combined effect of the high barrier laminate around the VIP and the (structural) edge profile along the circumference of the component. Especially the latter effect reduces the overall thermal performance significantly, the amount of which depending on the thermal conductivity and thickness of the core, the thermal conductivity and thickness of the face sheets and the width and thermal performance of the edge configuration. Until now, numerical calculation tools are used for estimating the overall thermal performance of building panels. This procedure however is time-consuming and does not give insight into the relations between relevant parameters. This paper therefore presents and numerically validates an analytical model for calculating this thermal edge effect, especially for thermally highly performing building components with vacuum insulation panels as core. The model however is generally valid for thermal shunting effects due to the edge of building panels. Based upon a comparison of analytical results and numerical data, it is shown that the inaccuracy of the analytical model compared to numerical data is less than about 10% within limitations specified. Based upon this analytical procedure, manufacturers, building scientists and architects can optimise the thermal performance of building constructions, thus contributing to the required energy reduction of buildings in their occupational phase and the desired well-being of building occupants.

description: assess doctor-patient communication at Adama Hospital Medical College (AHMC). Specifically, it assessed the communication competencies of medical doctors (with their own inpatients), investigated how inpatients interact with their doctors and evaluated the major barriers to doctorpatient medical communication. A descriptive, explanatory, and cross-sectional study designs were followed. Out of 66 medical doctors of AHMC, 36 were selected as they were more directly and highly involved with bed-ridden patients in six wards and the remaining 22 were much more occupied with teaching and the management of the hospital and were not readily available for this study. A total sample size of 180 (144 patients + 36 medical) respondents were included. An SPSS 16 was used for presenting quantitative data and emerging themes guided the qualitative data analysis. The study found out that all medical doctors practice greeting socially and treat patients with due respect. The qualitative data indicated that some doctors exhibited communicative competence failures, and some lacked the cultural competence needed to comprehend traditional expressions. Due to heavy workload, some medical doctors show lack of interest. However, almost all Generally, doctors allocated little time with patients who were not in a very critical situation. Almost all medical doctors assumed that they devoted their time to understand the main health concerns of patients and gave much attention. Those patients from the rural communities were often interrupted because they did not talk about their illnesses openly. This implies that some medical doctors lacked a profound knowledge of cultural communicative competence. Patients used traditional and vague expressions. Factors such as avoiding medical jargons, recounting the next steps, giving much care and concern, apportioning sufficient time, and writing legibly have been considered as major elements influencing medical communication. In the three factors (showing interest, understanding, and giving attention), doctors have been evaluated good communicators. This current study identified communication barriers and their possible causes. Some of these barriers have been caused due to poor communication skills, lack of the proper sense of confidentiality, the misuse or inappropriate use of medical jargons, lack of spacious level of education, inappropriate use of cultural and vague expressions, poor time allocation, evidence versus oral evidence and lack of family partnership and responsibility. Among other suggestions, the study recommends that the hospital needs to design a communication strategy to address these communication gaps.

description: objectives have been translated into reality in Adama city Land Development and Management Sector Office, Oromia Regional State, Ethiopia. Descriptive survey research designs with quantitative and qualitative methods were employed for the study. Primary data were collected using self administered, structured questionnaire from randomly selected 81 service providers (workers) and 89 service users (Customers). Moreover, by using availability sampling technique, seven leaders were selected and interviewed. The data collected from respondents were tailed, tabulated and organized in a systematic form. Statistical tools such as mean, standard deviation and t-test were used to analyze quantitative data. Qualitative data analysis was transcribed and discussed thematically. The results of the study were in agreement with the literature that reform is necessary for improved service delivery. However, the negative outcomes of the implementation of service delivery reforms by Adama City Land Development and Management Office outweigh the positive results. Specifically, the manifestation of culture that permits corrupt behaviour; eroded commitment by political leaders to fight corruption; lack of transparency, and weak concern for customer seriously affect the successful implementation practices in the sector office. Likewise, leaders and employees were not accountable for their decisions and actions. Therefore, the study recommends, the sector office should enhance goal-oriented competencies of service providers, apply code of conduct for public sector ethics and pragmatic anti-corruption strategies. Further, the Government needs to review the existing labour proclamation with the view of attaining sector mission and service delivery objectives.

description: Maize is one of most important food crop grown in Ethiopia and is produced in different agro-ecologies in the country. However, its productivity is constrained by a number of problems out of which is inappropriate fertilizers applications and undetermined planting space utilization. Therefore, the field experiment was conducted at Melkassa Agricultural Research Center in East Showa Zone, Oromia Regional State with the aim of identifying the effect of blended NPS fertilizer rates and intra-row spacing on growth and yields of maize during 2019 cropping season. The experiment was arranged in a factorial combination of five rates of blended NPS fertilizer (0, 75, 150, 225, 300 kg ha-1) and three intra row spacing (15, 25, 35cm) in a randomized complete block design in three replications. The result revealed that leaf width and grain yield was significantly (p<0.05) influenced by the interaction of NPS rates and plant spacing. The results showed that the above ground biomass and cob weight significantly affected by the main effect of spacing; while, cob length, stem diameter and leaf length were significantly influenced by both main effect of NPS fertilizer rates and plant spacing. Highest (13.67kg) above ground dry matter was recorded from the application of 300 kg NPS ha-1 at 35cm intra row spacing; while, the lowest (7.33 kg) was obtained from the control at 15 cm intra row spacing. Also highest grain yield (7400 kgha-1) was obtained from 300 kg NPS ha-1 applied at 15cm intra-row spacing and lowest (3833.30 kg ha-1) from control at 35cm intra-row spacing. The highest (17.07%) and lowest (13.93%) moisture contents were obtained from control at 35cm and 15cm intra-row spacing, respectively. Thus, it can be concluded that application of 300 kg NPS ha-1 at 15cm intra-row spacing was better for maize growth and yields under rain-fed cropping system in the study area. However, to give concrete recommendation similar experiments should be done to confirm the obtained results across locations and years in the same cropping system and the like.

The effect of air movement on the heat and moisture characteristics of building constructions
Creators: name: Van Schijndel, Jos

Publisher: name: 8th Symposium on Building Physics in the Nordic Countries
Year: 2008

description: The reduction of energy consumption related to buildings is of great importance. In order to calculate the energy consumption of a building, the heat transfer modeling of constructions is important. Moreover, some software tools also simulate moisture transport simultaneously to improve the design of building constructions. If we look more closely to these combined heat and moisture models, the effect of air movement inside the construction is not taking into account by almost all models. The main reasons are twofold: First, in practice it seems to have only a minor effect on the energy consumption. Second, the modeling and simulation of the air movement was quite complicated so far. The recent development of multiphysics modeling tools give cause to revisit the following problem: How important is the effect of air movement on the heat- and especially the moisture characteristics of building constructions? The method of research was as follows:  First, selection of a common building construction type. Second, modeling and simulation of six cases: 1D, 2D and 3D heat and moisture transport models each with and without air movement based on the selected construction. The used internal and external boundary conditions (i.e. temperature, humidity and wind induced pressures) were based on a local (Dutch) climate. Third, evaluation of the results.  The paper presents the details of the mentioned method and a discussion of the results. It is concluded that (as expected) the heat characteristic of the studied building construction is only minor affected by air movement. However, our results indicate that air movement seems to have much more impact on the moisture characteristic as presumed so far. Moreover, the use of multiphysics models enables and simplifies the research of possible important effects that are not included in other standard heat and moisture simulation tools.

description: In order to design a moisture safe slab on ground, a minimum temperature difference of approximately 3 degrees Celsius between the floor and the soil is often recommended. For a slab on ground with floor heating, the heat loss to the ground is greater than in a regular slab. However, the extra heat loss during the heating season results in a warmer soil. This may lead to an upward directed moisture flow during periods when the floor heating is switched off, which can cause moisture damages. In this paper, a new theoretical model that predicts the dynamical hygrothermal conditions in the foundation is presented for 3-d cases. The model can be used in the design of moisture safe foundations.

description: A new model for designing frost protection insulation has been developed. The new approach is that the heat flow from the slab to the ground is assumed to be zero, i.e. adiabatic surface, and that there is no shaft depth. In this way the complexity of the problem is simplified and the worst case scenario chosen. Using simulations in 2-d and using scaling technique show that the frost protection insulation dimension can be condensed to only using two equations and only one simulation is required. However, in corners the frost penetration is more severe. In this paper the frost front will be simulated in 3-d in order to validate the new design model for frost protection insulation for corners.

description: Following the detection of a long GRB 190919B by INTEGRAL (INTErnational Gamma-Ray Astrophysics Laboratory), we obtained an optical photometric sequence of its optical counterpart. The light curve of the optical emission exhibits an unusually steep rise ~100 s after the initial trigger. This behaviour is not expected from a 'canonical' GRB optical afterglow. As an explanation, we propose a scenario consisting of two superimposed flares: an optical flare originating from the inner engine activity followed by the hydrodynamic peak of an external shock. The inner-engine nature of the first pulse is supported by a marginal detection of flux in hard X-rays. The second pulse eventually concludes in a slow constant decay, which, as we show, follows the closure relations for a slow cooling plasma expanding into the constant interstellar medium and can be seen as an optical afterglow sensu stricto.

description: The container motion along a planar circular trajectory at a constant angular velocity, i.e. orbital shaking, is of interest in several industrial applications, e.g. for fermentation processes or in cultivation of stem cells, where good mixing and efficient gas exchange are the main targets. Under these external forcing conditions, the free surface typically exhibits a primary steady state motion through a single-crest dynamics, whose wave amplitude, as a function of the external forcing parameters, shows a Duffing-like behaviour. However, previous experiments in lab-scale cylindrical containers have unveiled that, owing to the excitation of super-harmonics, diverse dynamics are observable in certain driving-frequency ranges. Among these super-harmonics, the double-crest dynamics is particularly relevant, as it displays a notably large amplitude response, that is strongly favored by the spatial structure of the external forcing. In the inviscid limit and with regards to circular cylindrical containers, we formalize here a weakly nonlinear analysis via multiple timescale method of the full hydrodynamic sloshing system, leading to an amplitude equation suitable to describe such a super-harmonic dynamics and the resulting single-to-double crest wave transition. The weakly nonlinear prediction is shown to be in fairly good agreement with previous experiments described in the literature. Lastly, we discuss how an analogous amplitude equation can be derived by solving asymptotically for the first super-harmonic of the forced Helmholtz-Duffing equation with small nonlinearities.
Connecting Dark Gauge Symmetry to the Standard Model

description: Dark matter is postulated to be a neutral Dirac fermion, charged under a dark $U(1)_D$ gauge symmetry. Scalar partners of the quarks and leptons are also charged under $U(1)_D$. The dark gauge boson $Z_D$ and the dark Higgs boson $h_D$ enable either freeze-out or freeze-in mechanisms to account for the correct dark matter relic abundance. Dark number $D$ is connected to baryon number $B$ and lepton number $L$ through $D=3B+L-(2j)_{[mod~2]}$ where $j$ is the intrinsic spin of the particle.

description: Abstract: Strip foundation of concrete is traditionally used in Denmark where it is placed 0.9 m underneath the finished ground surface to reach stable non-freezing ground. New prefabricated lightweight elements used as strip foundation placed on the stable ground underneath the top soil layer, just 0.3 m underneath the finished ground surface, have been introduced and demonstrated as an alternative.
The prefabricated elements, made of expanded polystyrene (EPS), can be used as the strip foundation of a house of up to two storeys. The EPS element has been designed to comply with the new revised Danish Building Regulations and allow very little energy to be lost through the foundation element combining the concrete slab and the outer wall. The EPS element has been specially designed to form the base of a traditional double-brick wall, a traditional wood-stud wall, and combinations of lightweight concrete, brick and wood-stud walls within/separated by insulation.
This paper demonstrates the use of the introduced prefabricated EPS element used as strip foundation forming the base of a traditional single-family house. The house is a one storey house with an exterior wall made as a double-brick wall separated by insulation. The design criteria for the EPS element will be outlined and methods to establish stable non-freezing ground underneath the EPS element will be described. Furthermore it will be shown how the EPS element is handled on site. The paper will demonstrate two-dimensional finite difference calculations of the temperature underneath the foundation. Calculations will be compared with temperature measurements taken on site, at measurement points located along lines from under the strip foundation at the outer plinth and in continuation of these points underneath the building. In addition the soil temperature and temperature and relative humidity indoors and outdoors will be measured. Measurements cover the construction period as well as a period after completion.

description: Honors courses are a special opportunity to provide a small group of undergraduate students with the challenging and rewarding experience of doing original scholarly research. This session will focus on some of the major issues associated with managing and implementing a student-led research project. These include choosing a research topic, designing a methodology, organizing data collection and analysis, and presenting research findings. We shall pay particular attention to the nuts-and-bolts of managing the course and to the process of transforming students from consumers to producers of knowledge. The presenters are faculty members in the Department of Criminology, Law and Society who have both taught the course, but done so in different ways. Comparing and contrasting the promises and pitfalls of these approaches (interviews vs. surveys, single team vs. small groups, poster vs. oral presentation) promises to broaden the panelâ€™s appeal and its applicability to different disciplines.
