Abstract:
In history of art and architecture, surface has always been the bearer of symbolic and aesthetic values, the subject of theoretical and critical analysis, with various ideological, discursive and philosophical interpretations. The subject of this research paper are different concepts of composition, artistic elements and materialisation of fa?ade surfaces, which have the effect of ?surface depth? as their primary characteristic. By analysing the potential of this concept in articulation of the structure of fa?ade and other surfaces, three main emergent forms were noted: plasticity of surfaces (the use of small fa?ade plastics), double skin fa?ade with unused in-between space and double skin fa?ade with used in-between space. By conducting scientific analyses of theoretical reference sources and characteristic examples, along with the application of the deductive methods, the characteristics of the ?surface depth? concept in architecture were explored, with the aim of systematizing the principles used to achieve it, the possibilities of its application, as well as ways to establish the dual character of spatial planes - surface and volume. This research has contributed to the clarification of this concept and laid the foundation for further research in the direction of finding, chronologically ordering and analysing other examples, in order to enable their more extensive typology and systematization.

Abstract:
The main point of a physical definition of surface forces in the matter in general, especially in the nuclear matter, is that the curvature of surfaces and its variation should be physically defined. The forces are therefore just the vehicles of introducing physics. The problem of mathematical definition of a surface in term of the curvature parameters thus naturally occurs. The present work addresses this problem in terms of the asymptotic directions of a surface in a point. A physical meaning of these parameters is given, first in terms of inertial forces, then in terms of a differential theory of colors, whereby the space of curvature parameters is identified with the color space. The work concludes with an image of the evolution of a local portion of a surface.

Abstract:
Bacterial environmental colonization and subsequent biofilm formation on surfaces represents a significant and alarming problem in various fields, ranging from contamination of medical devices up to safe food packaging. Therefore, the development of surfaces resistant to bacterial colonization is a challenging and actively solved task. In this field, the current promising direction is the design and creation of nanostructured smart surfaces with on-demand activated amicrobial protection. Various surface activation methods have been described recently. In this review article, we focused on the “physical” activation of nanostructured surfaces. In the first part of the review, we briefly describe the basic principles and common approaches of external stimulus application and surface activation, including the temperature-, light-, electric- or magnetic-field-based surface triggering, as well as mechanically induced surface antimicrobial protection. In the latter part, the recent achievements in the field of smart antimicrobial surfaces with physical activation are discussed, with special attention on multiresponsive or multifunctional physically activated coatings. In particular, we mainly discussed the multistimuli surface triggering, which ensures a better degree of surface properties control, as well as simultaneous utilization of several strategies for surface protection, based on a principally different mechanism of antimicrobial action. We also mentioned several recent trends, including the development of the to-detect and to-kill hybrid approach, which ensures the surface activation in a right place at a right time.

Abstract:
Background. Students’ conceptualization of learning has been associated with their approaches to studying. However, whether students’ learning concepts are associated with their personal characteristics is unknown. Aim. To investigate whether sociodemographic, education-related, and personal factors were associated with the learning concepts of Norwegian occupational therapy students. Methods. One hundred and forty-nine students (mean age 23.9 years, 79.2% women) participated in the study. The employed self-report questionnaires included the Approaches and Study Skills Inventory for Students, the Rosenberg Self-Esteem Scale, and the General Self-Efficacy Scale. Differences between student cohorts were analyzed with one-way analyses of variance and χ2 tests, whereas factors associated with the students’ learning concepts were analyzed with bivariate correlation and linear regression models. Results. The students’ mean scores on the deep and surface learning concept scales were similar. Spending more time on the independent study was associated with having higher scores on the unidimensional learning concept measure. Conclusions. The students’ learning concept appears to encompass a surface concept as well as a deep concept of learning, and the two ways of conceptualizing learning were positively related to each other. Over time, a mature deep concept may add to, rather than replace, a basic surface concept of learning.

Abstract:
A newly developed clinical method of indexing tibial torsion uses the medial surface of the tibia as the proximal reference; however, the selection of a specific landmark on the medial surface has not been justified. Three different surfaces relating to the tibial tuberosity were tested using 24 dry tibial bones to determine which provides the most accurate and reliable landmark for use as the proximal reference. The medial surface of the tibia at the inferior point of the tibial tuberosity was the most reliable proximal reference that yielded the highest level of association between the newly developed clinical method and true tibial torsion (r = 0.77). The new method has the potential to describe the anatomy of the leg and to improve the clinical measurement of tibiofibular torsion. (J Am Podiatr Med Assoc 95(5): 481–485, 2005)

This capstone project explored the operational and design considerations/constraints for an autonomous Unmanned Surface Combatant (USC). Using a USC in selected missions could lead to cost reductions and enhanced capabilities when compared with similar manned combatants by eliminating personnel and automating ship operations. Operations and Support (O&S) costs, which include personnel costs, are a large portion of the Navy's total ownership costs (TOC) for surface combatants, and can be as high as 38 percent of the TOC. Enhanced capabilities for a USC could be derived from performing operational activities manned ships cannot
and automated tasks could be performed more efficiently and effectively by a computer system than a human. A modified waterfall systems engineering process model was used to explore a USC concept. A needs analysis was performed, and mine warfare and anti-submarine warfare were identified as appropriate military missions for an initial USC concept. Top level constraints for a USC concept and support missions were developed. Design considerations, relevant technologies, and concept risks were investigated. This capstone project concluded that a lower cost, higher capability autonomous USC is possible based on the current state of relevant technologies. However there are significant technical challenges to overcome before full autonomy is possible. Further, more rigorous design studies are recommended.

It is estimated that 70 to 85 percent of a naval ship's life-cycle cost is determined during the concept exploration phase which places an importance in the methodology used by the designer to select the concept design. But trade-off studies are guided primarily by past experience, rules-of-thumb, and designer preference. This approach is ad hoc, not efficient and may not lead to an optimum concept design. Even worse, once the designer has a "good" concept design, he has no process or methodology to determine whether a better concept design is possible or not. A methodology is required to search the design space for an optimal solution based on the specified preferences from the customer. But the difficultly is the design space, which is non-linear, discontinuous, and bounded by a variety of constraints, goals, and thresholds. Then the design process itself is difficult to optimize because of the coupling among decomposed engineering disciplines and sub-system interactions. These attributes prevent application of mature optimization techniques including Lagrange multipliers, steepest ascent methods, linear programming, non-linear programming, and dynamic programming. To further improve submarine concept exploration, this thesis examines a statistical technique called Response Surface Methods (RSM). The purpose of RSM is to lead to an understanding of the relationship between the input (factors) and output (response) variables, often to further the optimization of the underlying process. The RSM approach allows the designers to find a local optimal and examine how the design factors affect the response in the region around the generated optimal point. RSM can be applied to submarine concept exploration and provide a methodology to: determine the optimal concept design based on customer preference, efficiently perform trade-off studies, determine the feasible design space, and the ability to determine in advance if a specified concept design is feasible and meets all the customer thresholds and constraints.

Abstract:
Les propriétés de surface, particulièrement microgéométriques, jouent un rôle essentiel dans tous les systèmes tribologiques. L’analyse de la répartition des efforts de contact dans l’interface entre surfaces rugueuses est indispensable à la prédiction du frottement, de l'usure, de l'adhérence, des résistances de contact électrique et thermique… De nombreux modèles ont été proposés ces dernières décennies pour prédire les efforts entre aspérités de surfaces rugueuses. Parmi ces modèles, les modèles statistiques sont majoritairement développés en considérant le contact ente une surface rugueuse équivalente, la surface somme - qui tient compte des microgéométries des deux surfaces en contact ainsi que de leur matériau - et un plan lisse. Cependant la validité de cette modélisation n’a pas été clairement démontrée. L’objectif de notre étude a été de développer un modèle statistique de contact entre deux surfaces rugueuses isotropes aléatoires puis de comparer les résultats obtenus pour ces deux surfaces avec ceux obtenus en considérant la surface somme définie classiquement à partir des deux surfaces rugueuses et un plan lisse. Les différences entre les résultats nous ont amenés à proposer une nouvelle modélisation de la surface somme
Surface properties, particularly micro-geometry, play a key role in all tribological systems. The analysis of the distribution of contact forces in the interface between rough surfaces is essential for the prediction of friction, wear, adhesion, electrical and thermal contact resistance... Many models have been proposed during the last decades to predict the forces between asperities of rough surfaces. Among these models, statistical models are mainly based on the contact between an equivalent rough surface, the sum surface - which combines micro-geometry of the two surfaces in contact and their material - and a smooth plane. However, the validity of this model has not been clearly demonstrated. The aim of our study was to develop a statistical model of the contact between two random isotropic rough surfaces and then compare the results with those obtained by considering the classical sum surface. The differences between the results have led us to propose a new definition for the sum surface

Abstract:
Swerea KIMAB is one of Europe’s leading institutes for metallic materials and excels in many different areas. KIMAB’s main advantage is its open internal structure where all groups and projects can share information and knowledge between the sections. After moving to new premises it was noted that the surface fatigue test rig that had been used had started to leak oil and was no longer suitable for new projects. Because surface fatigue testing will be of importance in the future for the development of new alloys that will replace existing alloys in for example gears, this thesis was created as a foundation for how a new test rig should be acquired.This thesis goal is to describe KIMAB’s requirements in a test rig and to do a market screening over existing solutions for test rigs. Thereafter a designed concept shall be developed for KIMAB’s specific requirements and describe how it should be made. These different parts will be the ground for how KIMAB should continue in the acquisition of a new rig.The base of the thesis is a literature study in surface fatigue, its mechanics and how these can be affected to give the desired test scenario. This information is used to make a market screening for suitable test rigs that fulfils the requirements. Thereafter a concept generation is made and evaluated during a meeting on KIMAB. The chosen concept will then be designed to be user friendly, robust and as reliable as possible.When the final concept is done and quotes from manufacturers have been gathered for most of the parts in the design, a time and cost estimation was made to give the reader the chance of deciding which alternative is the most suitable for KIMAB. This choice has to be made with regard to future projects and how the market will develop for the ordering of surface fatigue testing.
Swerea KIMAB är ett av Europas ledande institut för metalliska material med spetskompetens inom ett flertal områden. KIMAB’s stora fördel är dess öppna interna struktur där alla grupper och projekt kan dela information och kunskap emellan avdelningarna. Efter att KIMAB flyttade till nya lokaler uppmärksammades det att den kontaktutmattningsrigg de använt under flera år började läcka olja och inte längre var optimal för dagens projekt. Eftersom kontaktutmattning kommer att bli ett viktigare inslag i framtiden då nya legeringar kommer att ersätta befintliga i exempelvis kugghjul, så skapades detta examensjobb som en grund för hur en ny rigg skall införskaffas.Detta examensjobb har som mål att beskriva KIMAB’s behov i en testrigg samt att göra en marknadsundersökning efter befintliga riggar. Därefter skall ett förslag designas på hur en testrigg som är anpassas just för KIMAB’s behov skall kunna byggas. Dessa delar skall sedan ligga som grund för hur KIMAB skall gå vidare i införskaffandet av en ny rigg.Examensarbetets grund ligger i en litteraturstudie i kontaktutmattningsskador samt mekanismerna bakom dessa skador och hur de kan påverkas i ett test scenario. Denna kunskap användes för att undersöka marknaden efter lämpliga riggar som kan uppfylla kraven. Därefter skapades ett antal koncept som utvärderades under ett möte på KIMAB. Det koncept som valdes har därefter designats för att vara så användarvänligt och tillförlitligt som möjligt.När konceptet var färdigställt och prisuppgifter hämtats in på merparten av delarna så har en kostnads och tidskalkyl utförts för att låta läsaren avgöra vilket alternativ som passar bäst för KIMAB. Detta val måste baseras på framtida projekt och hur marknaden ser ut för beställning av kontaktutmattningsprover.

Abstract:
In 2010 about 25% of the Swedish coastal areas had been surveyed with modern bathymetry methods, the rest was surveyed with older methods in the 1800s. By 2015 this portion has increased to 48% and the Swedish Maritime Administration's goal is to have surveyed 75% by 2020. The remaining 25% consists mostly of shallow water with a depth of less than 10 meters. These areas are di-cult to measure with conventional methods; surveying ships equipped with a multi-beam sonar. Of these areas the Swedish Maritime Administration intend to survey 15% by 2022. This is only possible if newer technologies are made available for surveying shallower waters. This thesis is a part of a project developing an autonomous vessel suited for bathymetric surveying in shallow waters. The thesis focuses on the proof of concept as well as the development and testing of a prototype vessel and its systems. The benet of an autonomous vessel like this is that it is supposed to be cheaper and easier to operate than a smaller ship with sonars operated by a crew.

Abstract:
General concept. The reported 1-year study tested the feasibility ofpreparing antimicrobial and antioxidant nanoparticlesfunctionalized with natural phenolic compounds, as a first step to reach the ultimate goal - improving safely and quality of foods by developing novel antimicrobial and antioxidant food-contacting materials. The secondary objectives of the study were (a) selecting the most promising phenoliccompounds, (b) building nanoparticles with the selected phenolicgrafted on their Surface, and (c) testing antimicrobial and antioxidant properties of these particles. The study was expected to provide a " go/no go" decision as concerning the prospects of phenolic- bound nanoparticles as antimicrobial and antioxidant agents. Results. In course of the feasibility study, curucminwas chosen as the most promising phenoliccompound due to its high antibacterial activity exceeding other tested compounds by at leas one order of magnitude. Lipsome-typephospholipid/polydiacetylene(PDA) nanoparticlesfunctionalizedwith curcuminwere successfully built. The pitfall of limited curcumin amount that could be covalently bound to theparticle surface was circumvented by inclusion of curcunun in the liposome body. It was suggested onthe basis of fluorescence spectroscopy that curcuminwas bound by hydrophobic forces in the bi1ayer periphery of the Liposomesand therefore mightexert a contact effect on microorganisms. The curcumin­ functionalizednanoparticles(CFN) were shown to have a strong bactericidal activity towards both Gram-negative (E. coli) and Gram-positive (B. ce,·e11s) bacteria, but only limited effect against yeast. Furthermore, beyond the originallyplanned objectives, preliminary trials showed that CFN could be bound to silanized glass surface rendering aנבtiנnicrobial activity to the glass.

Abstract:
Autonomous vehicles (AV) and advanced driver-assistance systems (ADAS) offer multiple safety benefits for drivers and road agencies. However, maintaining the lateral position of an AV or a vehicle with ADAS within a lane is a challenge, especially in adverse weather conditions when lane markings are occluded. For significant penetration of AV without compromising safety, vehicle-to-infrastructure sensing capabilities are necessary, especially during severe weather conditions. This research proposes a method to create a continuous electromagnetic (EM) signature on the roadway, using materials compatible with existing paving materials and construction methods. Laboratory testing of the proposed concept was performed on notched concrete-slab specimens and concrete prisms containing EM materials. An induction-based eddy-current sensor and magnetometers were implemented to detect the EM signature. The detected signals were compared to evaluate the effects of sensor height above the concrete surface, type of EM materials, EM-material volume, material shape, and volume of EM concrete prisms. A layer of up to 2 in. (5.1 cm) of water, ice, snow, or sand was placed between the sensor and the concrete slab to represent adverse weather conditions. Results showed that factors such as sensor height, EM-material volume, EM dosage, types of the EM material, and shape of the EM material in the prism were significant attenuators of the EM signal and must be engineered properly. Presence of adverse surface conditions had a negligible effect, as compared to normal conditions, indicating robustness of the presented method. This study proposes a promising method to complement existing sensors’ limitations in AVs and ADAS for effective lane-keeping during normal and adverse weather conditions with the help of vehicle-to-pavement interaction.

Abstract:
Analytical methods to rapidly detect explosive compounds with high precision are paramount for applications ranging from national security to environmental remediation. This report demonstrates two proof-of-concept electroanalytical methods for the quantification of 2,4-dinitroanisol (DNAN) and pentaerythritol tetranitrate (PETN). For the first time, DNAN reduction was analyzed and compared at a bare graphitic carbon electrode, a polyaniline-modified (PANI) electrode, and a molecularly imprinted polymer (MIP) electrode utilizing PANI to explore the effect of surface-area and preconcentration affinity on the analytical response. Since some explosive compounds such as PETN are not appreciably soluble in water (<10 μg/L), necessitating a different solvent system to permit direct detection via electrochemical reduction. A 1,2-dichloroethane system was explored as a possibility by generating a liquid-liquid extraction-based sensor exploiting the immiscibility of 1,2-dichloroethane and water. The reduction process was explored using a scan rate analysis to extract a diffusion coefficient of 6.67 x 10⁻⁶ cm/s, in agreement with literature values for similarly structured nitrate esters. Once further refined, these techniques may be extended to other explosives and combined with portable electrochemical hardware to bring real-time chemical information to soldiers and citizens alike.
