THE EXPERIMENTAL RESEARCH OF PERCEPTION OF MODERN CHARACTERS IN A GROUP OF PRIMARY SCHOOL STUDENTS

Nowadays we can run across various applications of modern technologies in all areas of social life. One of these applications is also an eye tracking technology that helps to answer questions related to human-computer interaction. Through the eye tracking technology we have tried to find out how primary school students perceive well-known comics characters with whom they come into contact through various information and communication technologies. Such a study is important in order to determine to which superhero characteristics children tend to be more inclined. Another reason why we decided to focus on this research is that there are currently no publications dealing with the issue. The main conclusion drawn from this research is the fact that primary school students are mainly interested in the positive characters of superheroes, but there are some other features that influence the perception of children, for example the colourful appearance of the character or the interesting equipment the character uses.
Analysis of Distribution Generation Influences on the Vol- tage Limit Violation Probability of Distribution Line

Considering the time-sequence characteristic and randomness of load and natural resources, this paper studies on the distributed generation (DG) impacts on voltage limit violation probability of distribution lines. The time-sequence characteristic and randomness of load, wind and photovoltaic (PV) generation are analyzed; the indices and risk levels of voltage limit violation probability of node and distribution line are proposed. By using probabilistic load flow based on semi-invariant method, the impact degrees of voltage limit violation are calculated with different distributed power penetration levels, different seasons, different time periods, different allocation ratio between the wind power and PV power. Voltage limit violation laws of distribution line, which are concluded by IEEE33 bus system simulation, are very helpful to guide the voltage regulation of distribution line including distributed generation.
A Simple Explanation of the Taylor Rule

The modern New Keynesian literature discusses the stabilising properties of Taylor-type interest rate rules mainly in the context of complex optimising models. In this paper we present a simple alternative approach to provide a theoretical rationale for the adoption of the Taylor rule by central banks. We find that the Taylor rule can be derived as the optimal interest rate rule in a classical Barro-Gordon macroeconomic model. The successful practice of central bankers, at the core of the Great Moderation, and currently re-invoked to re-normalise monetary policy after the unprecedented quantitative-easing actions aimed to escape the Great Recession, can perfectly be explained by standard theory, without recourse to more complicated derivations.
Design of a Micro-Hopper Array for Multi-Material Powder Deposition 155

We present a concept for creating patterned beds of multi-material powder particles using an array of small-scale hoppers. Using this technique, we propose that to place fine particles of multiple fluidized powders discretely in a thin layer as opposed to depositing an entire powder layer of uniform composition using a roller device or doctor blade. Processing and consolidation of multiple, patterned powders can enable fabrication of composite objects with spatially varying structural and multifunctional characteristics. Although theory on the design of small-scale hoppers is lacking, our design for a hopper, its valving, and its particle delivery system are guided by background theory for large hoppers. A hopper array configuration is proposed, and a calculation for deposition time is presented. Delivery of powder was achieved on a prototype hopper. Experimentally measured mass flow rates were used to justify the use of this hopper with SLS and to guide further design improvements. INTRODUCTION The variety of applications for multi-material composite structures is both well established and growing rapidly. However, a present obstacle to continued growth lies in the approaches to manufacturing these types of artifacts. The development of new approaches for fabricating multi-material components is in part dependent upon developing SFF techniques capable of depositing and consolidating multiple materials. In particular, the selective laser sintering (SLS) process is well suited to this challenge. A means of incorporating the delivery of multiple powders in SLS may enable the production of complex, multi-functional and intelligent components. Figure 1.

Hierarchical Velocity Control Based on Differential Flatness for a DC/DC Buck Converter-DC Motor System

This paper presents a hierarchical controller that carries out the angular velocity trajectory tracking task for a DC motor driven by a DC/DC Buck converter. The high level control is related to the DC motor and the low level control is dedicated to the DC/DC Buck converter; both controls are designed via differential flatness. The high level control provides a desired voltage profile for the DC motor to achieve the tracking of a desired angular velocity trajectory. Then, a low level control is designed to ensure that the output voltage of the DC/DC Buck converter tracks the voltage profile imposed by the high level control. In order to experimentally verify the hierarchical controller performance, a DS1104 electronic board from dSPACE and Matlab-Simulink are used. The switched implementation of the hierarchical average controller is accomplished by means of pulse width modulation. Experimental results of the hierarchical controller for the velocity trajectory tracking task show good performance and robustness against the uncertainties associated with different system parameters.
ESTIMATING IN-SITU THERMAL CONDUCTIVITY FROM LOG DATA 1

Hole 857C, drilled in Middle Valley, northern Juan de Fuca Ridge, during Leg 139 of the Ocean Drilling Program, penetrated about 470 m of turbidite sediments. Below the sediments the hole intersected a series of basaltic sills interbedded with sediments. Hole 857C is located south of an active hydrothermal vent field in an area where seafloor heat flow measurements show values exceeding 0.8 W/m. This hole was successfully logged with the seismic and lithodensity tool string. Open-hole temperatures at a depth of 480 mbsf are as high as 222°C. The porosity profile of Hole 857C, based on log-derived wet-bulk densities, forms the basis for the calculation of a thermal conductivity profile using a binary mixture of sediment grains and seawater and a geometric mean model. The thermal conductivity of the grains is assumed to be 2.6 W/m-K (Davis and Seeman, this volume). High temperatures encountered in Hole 857C require that temperature effects on the thermal conductivity must be included. The variation of the thermal conductivity of seawater is well known. The decrease of the thermal conductivity of the grains with increasing temperature is calculated after Sass et al. (1992) and Chapman et al. (1984). A purely conductive vertical heat flow is assumed to allow the iterative modeling procedure caused by the nonlinear nature of the problem. The model calculations show that the results of a simple model with constant thermal parameters are similar to those of a model that includes a temperature-dependent seawater thermal conductivity and temperature coefficient of the grain thermal conductivity after Sass et al. (1992). This surprising result is a consequence of the competing effects of decreasing porosity with depth, decreasing thermal conductivity of the grains with depth (and temperature), and the variation of the thermal conductivity of seawater with temperature. Results based on temperature corrections of Chapman et al. (1984) give unrealistically high temperatures at the base of the sediments. Varying the grain thermal conductivity between 2.6 and 3.2 W/m-K results in a range of thermal conductivity profiles that predict temperatures that are in agreement with observed vent fluid temperatures.
Theatre teaches

Theatre teaches is a new experiment carried out at the University of Brescia. The growing importance of transversal competences i.e. those skills that essentially concern attitudes in the workplace and interpersonal relationships such as team work, language and communication skills, gave us the idea to develop an educational innovation to help students bring out these skills. We asked students to wrote a play using topics seen in class. So, they tried to wrap their mind around it and worked in team to write a script and get him to scene. Not to be confused to business theatre, this method is applicable in any framework. The assessment results reveal that students appreciate this method because this work helps them to express theirself better and, in general terms, they could improve their non techniocal skills. In conclusion, we can say that this experiment has been a success and gave the students the opportunity to show transversal competences. The ability to communicate, to teamworking, to manage conflicts, to speak in public, to problem solving, creativity, imagination, the ability to manage unforeseen situations and tolerate pressure and stress, leadership skills, negotiation skills and the ability to motivate are just few of the emergent competences.
The efficacy of Cognitive Behavioral Therapy in patients with chronic musculoskeletal pain

Introduction: Chronic pain is one of the most prevalent reasons of referral to health centers. Cognitive Behavioral Therapy (CBT) has been shown to be an effective treatment for chronic pain. The current study was conducted to evaluate the efficacy of Cognitive Behavioral Therapy in patients with chronic musculoskeletal pain. Materials and Methods: CBT was evaluated in 8 sessions of up to 50 minutes in 4 patients with chronic musculoskeletal pain. A multiple baseline with a follow up of 1 month was used. Patients were randomly allocated to baselines and outcome and assessed via Beck Depression Inventory (BDI), Pain Catastrophizing Scale (PCS), Visual Analogue Scale (VAS) and Cognitive Coping Strategies Inventory (CCSI). Results: Results showed that Cognitive Behavioral Therapy was effective in reduction of depression, pain Catastrophzing and pain intensity, and improvement of coping strategies. These effects were maintained to some extent in the follow up. Conclusion: Psychological as well as medical treatment can be helpful in the patients with chronic pain.
Voiding profile in recipients post renal transplant: A prospective observational study

Background: Renal transplantation (RTX) is thought to have high survival rates. However, patients with long-term dialysis have decreased bladder function due to disuse. High urine production after RTX surgery might cause patients to have urinary symptoms, thus decreasing their quality of life. The aim of this study was to evaluate voiding characteristics of patients after RTX surgery. Methods: All patients were diagnosed with chronic kidney disease (CKD) and underwent kidney transplantation from a living donor. Anthropometric parameters, physical examinations, cause of CKD, daily urine production, types and duration of dialysis, and basic laboratory examination were collected before transplant surgery. Post-operative examinations included laboratory examination, international prostate symptom score (IPSS; for male patients only), overactive bladder symptom score (OABSS), uroflowmetry, and post void residue (PVR). Results: 71 patients were evaluated with a mean age of 46 ± 17.9 years, with male and female ratio of 52:19. Significant negative correlation was seen between duration of dialysis and daily urine production (r: -0.68, p<0.01). Majority of patients had a maximum flow rate of >15 cc/s (70.4 %) with average flow of 22 ± 9.8 cc/s. The majority of patients had PVR <100 cc (91.5%) with median PVR of 33.5 cc (range, 2.3 – 142 cc). IPSS result showed that frequency [2 (0 – 5)] and nocturia [2 (0 – 5)] are the main problem in these patients (n = 52). OABSS questionnaire also showed that frequency (OABSS 1; score 1 [1-2]) and nocturia (OABSS 2; score 2 [0-3]) was the main symptoms reported by patients. Conclusion: After RTX, the majority of patients experienced urinary frequency and nocturia problems due to various causes such as increased daytime and nighttime urine production, urinary tract infection, changes in bladder capacity (both small and large), and a decrease in bladder compliance.
Long‐term Differences in Tillage and Land Use Affect Intra‐aggregate Pore Heterogeneity

Recent advances in computed tomography provide measurement tools to study internal structures of soil aggregates at micrometer resolutions and to improve our understanding of specific mechanisms of various soil processes. Fractal analysis is one of the data analysis tools that can be helpful in evaluating heterogeneity of the intra-aggregate internal structures. The goal of this study was to examine how long-term tillage and land use differences affect intra-aggregate pore heterogeneity. The specific objectives were: (i) to develop an approach to enhance utility of box-counting fractal dimension in characterizing intra-aggregate pore heterogeneity; (ii) to examine intra-aggregate pores in macro-aggregates (4-6 mm in size) using the computed tomography scanning and fractal analysis, and (iii) to compare heterogeneity of intra-aggregate pore space in aggregates from loamy Alfisol soil subjected to 20 yr of contrasting management practices, namely, conventional tillage (chisel plow) (CT), no-till (NT), and native succession vegetation (NS). Three-dimensional images of the intact aggregates were obtained with a resolution of 14.6 {micro}m at the Advanced Photon Source, Argonne National Laboratory, Argonne, IL. Proposed box-counting fractal dimension normalization was successfully implemented to estimate heterogeneity of pore voxel distributions without bias associated with different porosities in soil aggregates. The aggregates from all three studiedmore » treatments had higher porosity associated with large (>100 {micro}m) pores present in their centers than in their exteriors. Pores 15 to 60 {micro}m were equally abundant throughout entire aggregates but their distributions were more heterogeneous in aggregate interiors. The CT aggregates had greater numbers of pores 15 to 60 {micro}m than NT and NS. Distribution of pore voxels belonging to large pores was most heterogeneous in the aggregates from NS, followed by NT and by CT. This result was consistent with presence of very large pores associated with former root channels in NT and NS aggregates. Our findings indicate that mechanisms of macro-aggregate formation might differ in their importance in different land use and management practices. « less
Pedagogical Knowledge

This exploratory study examined the structure of declarative knowledge about pedagogy housed in the memory of an experienced teacher educator, and it sought to determine the teacher educator's influence on the development of declarative knowledge structures in undergraduate students enrolled in three sections of a physical education teaching methods course. The Pathfinder scaling algorithm, an associative networking technique, was used to map the pedagogical knowledge structures of the teacher educator and undergraduate students before and following participation in the course. Comparison of students' knowledge of key pedagogical concepts with the instructor's indicatcd that students' knowledge was more coherent a,d corresponded more closely to the instructor's following the courses; final measures of correspondence and coherence were significantly associated with course performance. Also, university grade point average (GPA) was highly related to course performance variables while American College Test (ACT) scores were not. A follow-up of a subset of students indicated that key pedagogical concepts were retained over a six-month period of time. However, performance on a semantic ,lassification task of pedagogical concepts provided little evidence that students most highly correspondent with the instructor organized knowledge at a more semantic level than students who were less correspondent.

2 . 1 Manifold Interpolation-An Harmonic Extension Approach

We replace the output layer of deep neural nets, typically the softmax function, by a novel interpolating function. And we propose end-to-end training and testing algorithms for this new architecture. Compared to classical neural nets with softmax function as output activation, the surrogate with interpolating function as output activation combines advantages of both deep and manifold learning. The new framework demonstrates the following major advantages: First, it is better applicable to the case with insufficient training data. Second, it significantly improves the generalization accuracy on a wide variety of networks. The algorithm is implemented in PyTorch, and code will be made publicly available.
INFLUENCE OF TECHNOLOGICAL PARAMETERS OF THE ULTRAFILTRATION PROCESS OF CITRUS JUICES ON THEIR QUALITY

Fresh fruit juices contain organic acids and mineral substances (potassium, calcium, iron, copper, magnesium, phosphorus, manganese, molybdenum, boron, iodine), and their salts, large amounts of fiber, pectin and enzymes - complex substances, that contribute to the food processing and absorption of nutritional elements. Natural citrus juices contain essential vitamins and nutrients for the human body. Therefore, they represent a good opportunity for the treatment and prevention of various diseases. With the vitamins, taken through the juice, the human body becomes more resistant to viruses and infections, stressful situations and intense physical stress, and the body’s metabolism becomes normalized. Beverages, prepared from juices improve intestinal motility and thus contribute to improving the allocation of toxic substances and slags from the organism. The purpose of this work is the development of technological parameters of the ultrafiltration process to obtain natural juices which are sterile, resistant to precipitation and turbidity, and have a long shelf life. This paper examines the performance of the ultrafiltration process of citrus juices (lemon, tangerine, orange) and its dependence on the pressure and duration of the process, type and porosity of the membrane, the nature of the juice, and acidity. The juice composition was studied before and after ultrafiltration. It was established, that the productivity of the ultrafiltration process depends on: the duration of the process and this dependence is determined by the nature of the process: membrane type, in particular, filtration material and pressure: with an increase in membrane porosity and pressure, the productivity of the process, the volume of filtered juice, filtering speed and duration increases; the productivity of the ultrafiltration process, during the filtration both in dynamic and static mode, depends on the type and consistency of the juice: it increases with the increase of juice acidity. It was established: the general acidity (1.17%), density (1.038 g/cm3), the content of dry substances (9.9%), sugars (7.8%), including invert (7.2%), ash ( 0.26%), and vitamin C ( 20mg/ 100gr.), do not change in the course of ultrafiltration of tangerine juice. The viscosity, the content of carotenoids, cellulose and pectin decreases. The amino-acid structure practically does not change; hollow fibers detain only 6 - 8% of proteins and amino acids. For obtaining high-quality citrus juices, ultrafiltration should be carried out at a pressure 0.2MPa, on hollow fiber, in a dynamic, circulating mode. The juices obtained by ultrafiltration on hollow fibers (AP-2.0) are sterile, resistant to precipitation and turbidity, have significantly increased shelf lives, and they retain their organoleptic properties and nutritional values.
