Evaluating Information Quality of Corona Virus News on Iranian Health Websites

Background: Since websites are the first and most important source of information for the public, a comprehensive evaluation of the news and information content that they provide to the public is essential. This study aims to evaluate information quality of coronavirus news on Iranian health websites. Results: Evaluating 19 components in each website showed that COVID-19 patient information, self-assessment, and registration system website with a score of 2.85 is at a higher level among the health websites, and essential news and knowledge of corona virus website with the score of 1.1 is in poor quality. Conclusion: The difference between this study and other studies is in examining the quality of corona virus news. Other studies have examined the quality of health websites. These findings form the basis of recommendations for building a comprehensive, consistent, reliable, up-to-date, high-quality website that can meet people's needs.
Towards Open Science for the Qualitative Researcher: From a Positivist to an Open Interpretation

This reflection by a qualitative researcher stems from a concrete experience with data handling in a funded research project. The researcher followed Open Research Data guidelines and found optimal solutions to pseudonymise data, but this later evolved into a deep epistemological questioning on praxis. During the first phase of the project, a tailor-made software was developed with help from librarians and an IT professional to automate the pseudonymisation of the 150 data chunks generated by 16 students, 3 tutors and 3 decision makers. In the second phase of the project, this experience sparked questions about the meaning of such data handling and interpretations of Open Science, which led the researcher to suggest a framework for the professional development of qualitative researchers in their understanding of Open Science. The article raises awareness of normative frameworks in institutional data handling practices and calls for active contributions to defining qualitative research in an Open Science perspective, particularly taking as a reference the recent draft recommendation by UNESCO (2020)
Health Risks from Indoor Air Pollutants: Public Alarm and Toxicological Reality

The air, particularly the indoor air, contains a considerable burden of unwanted pollution. Overall there may be thousands of pollutants. They are brought in with the outside air or are generated from or within buildings. Most will be present in minute amounts but several will be present in measurable quantities. The reaction of people to the components of this pollution has little to do with toxicological assessment but is more concerned with political responses and media scares. The health effects from exposure to the very low levels commonly found in the indoor environment of materials such as combustion products, whether from coal, petrol or tobacco or to lead or asbestos fibres, are probably negligible but we worry about them. On the other hand, gases such as carbon monoxide or nitrogen dioxide which are not infrequently present in dangerous concentrations, many solvents and dust-generating DIY projects cause little concern. The distinction between concern and indifference is made without reference to any toxicological knowledge. Although it is certainly prudent, through source control, design and ventilation of buildings, to reduce all pollutants to the lowest level, concentrating on media favourites rather than more important dangers, including disease transmission, may well be a poor use of our resources.
Evaluation of heuristics for a class-constrained lot-to-order matching problem in semiconductor manufacturing

While semiconductors are being used in an increasing number of products, semiconductor manufacturers continually look for ways to make their processes more efficient. This paper will focus on an issue in the manufacturing process called the class-constrained lot-to-order matching problem (CLOMP), where individual lots of microprocessors are matched to customer orders, while seeking to optimize multiple objectives. Due to its complexity, the problem is decomposed into two stages—the first identifies which customer orders to fill while the second assigns specific lots to the chosen orders. We design an experiment with four first-stage sorting rules, four second-stage heuristics and two production cases. Based on our simulation results, this paper will recommend the first-stage sorting rule and second-stage heuristic which attain the best results with regards to our measures of effectiveness.
New types of silicon torsion microspring and their characterization

A number of methods for torque measurements in the macro domain exist, but only some of them can be scaled down to micro dimensions. This paper describes one method for measuring very small moments which is based on the measurement of torque by using silicon micro springs. Three different designs of torsion micro springs have been produced. The experimentally measured results show the possibility of torque measurement in the sub-(mu) Nm range.
Maximising energy efficiency in 3D multicore systems: a formalised approach

Three-dimensional integrated circuits (3D ICs) present an intriguing challenge for both circuit and system engineers due to their diverse cooling efficiency among the stacked dies. Several recent proposals advocate multiple techniques for thermal management of 3D ICs at different levels of the design, while operating within the confines of thermal heterogeneity. In this article, we analyse for the first time, the role of thermal heterogeneity on the energy efficiency of the system by incorporating temperature dependent leakage power. We develop a novel convex optimisation framework to optimise the energy efficiency in 3D ICs incorporating: (a) leakage aware thermal provisioning using temperature dependent full-chip leakage model, (b) heat flow in vertically stacked systems using a grid based compact thermal model and (c) a concrete application for workload provisioning in 3D multicore systems. Detailed simulation-based experiments with our proposed optimisation framework shows 5–17% improvement in the energy efficiency of a typical multicore system organised as 3D stacked dies.

Performance Evaluation of Arsi, Kereyu and Their Crossbred Cattle Under Current Climate Change in Mid Rift Valley of Oromia, Ethiopia

The study was conducted in Fentale and Boset districts, East Shoa Zone, Oromia Region, Ethiopia. The objective of this study was to identify morph metric variation between cattle breeds of Arsi, Kereyu and their crossbred, and to evaluate adaptive, productive (milk yield) and reproductive performance of these cattle breeds, and their crossbred in the mid rift valley of Oromia Region. Three PA’s from each district, a total of Six PA (Huluka, Kawa, Barchota, Benti, Kobo and Dakaedu) were selected purposively. Respondents’ were identified using purposive sampling technique. Kereyu, Arsi and crossbred cattle of the two were reared for, milk production, risk aversion and source of income. The major production constraints identified were feed shortage, water scarcity, disease and coverage of grazing land by invasive plants. Arsi cattle’s have long age at first mating (3.87±.17), age at first calving (4.66±0.2) and calving interval (1.50±0.125) than Kereyu (3.78±0.23, 4.52±0.25, 1.39±0.19) and crossbred (3.86±0.11, 4.64±0.12, 1.49±0.14) in both study location while the crossbred cattle have medium Values respectively. Arsi cattle have short Lactation length than kereyu and Crossbred (6.36, 7.51, 7.11months for Arsi, kereyu and crossbred respectively also similar for daily milk yield (1.26, 1.71 and 1.43). The farmers in the two district prefer Kereyu breed due to their ability to tolerate drought, disease and highly adaptable to the area where as Arsi breed of cattle was susceptible to feed shortage, water scarcity and disease than other breed in the area. This study revealed that the Arsi community in the study area prefers to mate breeding female of Arsi with bull of Kereyu breed.
Fast heuristic principle for spare capacity placement in mesh-restorable SONET/SDH transport networks

The authors propose a useful new insight into the problem of spare capacity design for mesh-restorable networks. A straightforward heuristic of average case complexity O(S) based on the new principle is within 21% (13% on average) of the minimum capacity and runs 8.5-80 times faster than the optimal integer program (IF). Application to evaluate benefits from six new span addition candidates in a 53 node, 81 span network yielded the correct rank-order of merit 650 times faster than optimal methods. This contributes to a practical assault on the problem of finding the globally best single or multiple new span additions in the evolution of large transport networks.
A Generalized Mathematical Model to Estimate Gas Turbine Starting Characteristics

This paper describes a generalized mathematical model to estimate gas tubine performance in the starting regime of the engine. These estimates are then used to calculate the minimum engine starting torque requirements, thereby defining the specifications for the aircraft starting system. Alternatively, the model can also be used to estimate the start up time at any ambient temperature or altitude for a given engine/aircraft starting system combination.
Postural Stability in Patients with Moderate Knee Osteoarthritis: Roles of the Visual Feedback and Dynamic Perturbations

Background. Knee osteoarthritis is the most common joint disease and one of the leading causes of disability in old age. The present study aims to analyze the stability of standing with and without perturbation in patients with moderate knee osteoarthritis. Methods. Twenty-eight (14 men with knee osteoarthritis and 14 healthy individuals) were evaluated for postural control. In standing tests, the effects of disease (osteoarthritis vs healthy), vision (open vs closed eyes), and support condition (quiet standing vs on the unstable plate) on balance were studied. Results. The results showed that the presence of knee osteoarthritis significantly reduced the root mean square of hip joint flexion in patients compared to the control group (p = .024). Elimination of vision and reducing the base of support by standing on an unstable plate led to local instability in the joints close to the perturbation, especially the ankle (p < .001). Center of pressure data also showed that the mean (p = .034) and variability (p = .003) of the anterior-posterior excursion was significantly higher in patients. Patients with knee osteoarthritis are more vulnerable to falling on an unstable plate. Conclusion. The body used a postural stiffening strategy to prevent falling forward, especially on an unstable plate, and postural adjusting in the medio-lateral direction. In rehabilitative treatments to prevent falls based on the sensory re-organization plans e.g. rocking board, foam standing, game therapy, etc. it may be more efficient to focus on the distal joint muscles.
Efficient computation of global resolvent modes

In this paper we propose a completely unique approach to unravel the inverse problem of three-dimensional die design for extrudate swell, employing a real-time active control scheme. To the present end, we envisioned a feedback connection between the corner-line finite element method, wont to predict the positions of the free surfaces of the extrudate, and therefore the controller. The corner-line method allows for local mesh refinement and transient flow to be taken under consideration (Spanjaards et al., 2019). We show the validity of this method by showing optimization results for 2D axisymmetric extrusion flows of a viscoelastic fluid for various Weissenberg numbers. In 3D we first provides a proof of concept by showing the results of a Newtonian fluid exiting dies with increasing complexity in shape. Finally, we show that this method is in a position to get the specified extrudate shape of extrudates of a viscoelastic fluid for various Weissenberg numbers and different amounts of shear-thinning. Extrusion may be a common production technique within the polymer processing industry to get products with a desired cross-section. during this process a polymer is molten and pushed through a die with a particular cross-sectional shape, to get a product (extrudate) with this same cross-sectional shape. A standard requirement on the extrudate is dimensional precision. However, the size of the extrudate are highly influenced by a phenomenon called extrudate swell, where the extrudate starts to expand thanks to internal stresses within the polymer once it leaves the die.
Impact of ICT on the organization structure elements: case of the Varazdin County

Organizations have been in research focus for many years, where research may include organizations' impact on their surrounding, while in others researchers' interest moves to the influence of certain factors on the organizational components, therewith on the efficiency of overall organizational activity. Traditional view commonly divided the factors on internal and external ones, which became improper in modern conditions. When considering contemporary division of organizational determinants on structural (formalization, specialization, hierarchy and authority, centralization, etc.) and contextual factors (organizational size, technology, environment, mission, organizational culture etc.), as a specific factor we have to extract information and communication technology (ICT). ICT impacts not only all the organizational structure elements, but comprehensively changes the effects of all the other mentioned structural and contextual factors, therefore becoming generic factor which cannot be classified into one of these groups. In this research, which is a part of more extensive exploration with aim to confirm or deny that hypothesis, we shall observe impact of ICT on organizational elements of different organizations. This paper analyzes the influence of ICT on the organization of public administrations offices on the case of the Varazdin County, based on the data collected by the interview and questionnaire method.
Application of the Fuel-Optimal Energy Management in Design Study of a Parallel Hybrid Electric Vehicle

In spite of occasional criticism they have attracted, hybrid vehicles (HVs) have been warmly welcomed by industry and academia alike. The key advantages of an HV, including fuel economy and environment friendliness, however, depend greatly on its energy management strategy and the way its design parameters are “tuned. ” The optimal design and sizing of the HV remain a challenge for the engineering community, due to the variety of criteria and especially dynamic measures related to nature of its working conditions. This paper proposes an optimal design scheme that begins with presenting an energy management strategy based on minimum fuel consumption in finite driving cycle horizon. The strategy utilizes a dynamic programming approach and is consistent with charge sustenance. The sensitivity of the vehicle’s performance metrics to multiple design parameters is then studied using a design of experiments (DOE) methodology. The proposed scheme provides the designer with a reliable tool for investigating various design scenarios and achieving the optimal one.
Switching behaviour of high voltage IGBTs and its dependence on gate-drive

Simulation results on high voltage 5.5 kV IGBTs are presented for both IGBTs with triangular shaped electrical field (Type A) and nearly rectangular electrical field distribution (Type B) under blocking voltage conditions. Measurement results of a 3.5 kV IGBT are compared with respective simulations. With unchanged gate-control, for high voltage B-type IGBTs a dramatic increase in switching speed is observed compared with A-type IGBTs, which may lead to destruction of the IGBT and the corresponding freewheeling diode. A study on the influence of the gate drive on the switching behaviour of the IGBT and the diode in the circuit is presented. Fundamental aspects of the switching of IGBT and diode, which are of general interest and apply also to power-MOSFETS, are revealed and are explained by a simple model. Remedies to avoid device failure caused by the increased switching speed of the B-type IGBT are shown.
On Vision-Based Orientation Detection Analysis of Industrial Object with Circular-Shape Features

For the need of accuracy orientation location about work piece with circle features in vision-based automatic assemble industry, a kind of orientation detection method about work piece based on monocular vision was presented to locate the work piece and then adjust the orientation of assembly parts to guarantee the assembly precision. Ellipse parameters and center point of contours about holes was solved by extracting the center and edge about given the work piece with four holes in the experiment, orientation and location about surface of work piece can be derived. And then Automatic assemble was implemented by orientation of work piece feeding back to robot manipulator to adjust the orientation of assembling part. Experiment analysis has demonstrated that the uncertain of position is less than 8 um and the uncertain of orientation is less than 5 degree.
Dynamic material flow analysis to support sustainable built environment development : with case studies on Chinese housing stock dynamics

Sustainability challenges raised by built environment development are two-folds: on the inflow side these include resource depletion and emission problems due to material production (pre-use); on the outflow side they include problems of construction and demolition waste (after-use). Understanding how the future construction inflow and demolition outflow will develop is essential for early recognition of these problems. A traditional approach is through extrapolation, which is risky because changes of trends may occur. A Dynamic Material Flow Analysis approach, based on the Law of Mass Preservation, provides a better framework for long-term projection. The challenge is to understand the dynamics of the built environment stocks. It is especially true for the emerging countries, where the combined influences of rapid economic development and urbanization have to be considered but are yet rarely investigated. This thesis develops the currently available approaches by including general socio-economic and specific urbanization-driven factors in China. Case studies on Chinese housing stock dynamics indicate: demolition activities in Chinese cities will continue to grow throughout the rest of the 21st century; a shrinking demand for residential steel may be expected over the next few decades, which may lead to a decrease in global steel consumption of up to 10%.
Light Weight Clay Bricks in Combination of Sludge Blended with Agro/Wastes

The objective of the study is to produce light weight bricks to use as an isolating layer. So, porous or light weight bricks were prepared from clay, sludge, agro/ashes as Saw dust ash (DSA), sugarcane bagasse ash (SCBA) and corn stalk ash (CSA) fired up to 900°C. Physical and mechanical properties were investigated. The chemical composition of the starting raw materials was carried out by XRF analysis. Results proved that the water absorption (25.51, 25.74 and 25.86%) and apparent porosity (29.31, 29.51 and 29. 68%) were slightly lowered up to 6 wt. % of these waste ashes, and then increased with further increase. The bulk density (1.9989, 1.9987 and 1.9985 g/cm3) and compressive strength (48.54, 48.45 and 48.26 MPa) improved and enhanced with the replacement up to 6 wt. %, and then diminished. So, the optimum ash content was not more than 6 wt. % because the substitution of more than that bad or adverse effect was exhibited. Results also proved that the physical and compressive strength was better in case of SDA > SCBA > CSA. The prepared fired bricks could be successfully used and preferred as isolating bricks against heat.
APPLYING DATA FUSION TECHNIQUES TO TRAVELER INFORMATION SERVICES IN HIGHWAY NETWORK

Data fusion techniques are applied to traveler information services and used to build an accident duration estimation function. The accident duration is estimated at the initial occasion of an accident. The data fusion procedure clusters the values of each factor into a small number of intervals and effectively smoothes the data noise to the model. In most experiments, the mean absolute percentage errors of the estimated outputs are under 25%, indicating an acceptable forecasting effect. Through the factor sensitivity analysis, time of day, number of vehicles & vehicle type involved in accidents, and geometry have high significance in conducting the accident duration models. The results confirm that the data fusion techniques are practical and reliable for developing traveler information systems. This study is granted by National Science Council, Taiwan, under the project number NSC93-2218-E-006-094. It shows very promising practical applicability of the proposed models in the Intelligent Transportation Systems context.
Partnering: definition, theory and evaluation

The concept of partnering in the construction industry stands for a collaborative way of working. Examples of partnering projects can be found on every continent. As suggested in the title this thesis makes contributions to three areas of partnering research: the definition of partnering, the theory behind partnering and how to evaluate the effects of the concept. The thesis consists of six papers with the following main results. A new definition of the concept is provided with the partnering flower in the first paper. This definition model is a concrete, flexible and structured way to define partnering. It forces people to concretise and pinpoint which components they include in partnering in a specific setting. The second paper uses contract theory to understand how partnering can be justified from an efficiency perspective. Partnering can either be seen as something that neutralises opportunism when there is an incomplete contract or something that reduces transaction costs for renegotiation of complete contracts when new information arises. Paper 3 is an empirical study of attitudes towards partnering in the Swedish construction industry, which complements the preceding studies. Among the results can be mentioned that support for the definition of partnering presented in paper 1 is found and that most respondents do not see partnering just as a new fad - a result that is consistent from 2004 to 2006. With the theory and the definition settled, it remains to evaluate the effects of partnering. This is done in two steps. The first step (in paper 4) is through reviewing earlier evaluations and providing suggestions on how the assessments can be improved. One of these suggestions is applied in paper 5, with a quasi-experimental evaluation of partnering comparing ten partnering projects to ten similar non-partnering projects. With improved data, mainly based on site meeting minutes, and a more well-founded method, no support can be found for the strong positive outcome of partnering reported in earlier evaluations. The final paper makes a contribution to economic contract theory by questioning one of the essential assumptions in this literature, the distinction between observable and verifiable characteristics. This aspect surfaced during the study of partnering contracts and contract theory (A). This thesis is available at http://urn.kb. se/resolve? urn=urn:nbn:se:kth:diva-4355.
