Secure Data Sharing With AdHoc

In the scientific circles, there is pressing need to form temporary and dynamic collaborations to share diverse resources (e.g. data, an access to services, applications or various instruments). Theoretically, the traditional grid technologies respond to this need with the abstraction of a Virtual Organization (VO). In practice its procedures are characterized by latency, administrative overhead and are inconvenient to its users. We would like to propose the Manifesto for Secure Sharing. The main postulate is that users should be able to share data and resources by themselves without any intervention on the system administrator's side. In addition, operating an intuitive interface does not require IT skills. AdHoc is a resource sharing interface designed for users willing to share data or computational resources within seconds and almost effortlessly. The AdHoc application is built on the top of traditional security frameworks, such as the PKI X.509 certificate scheme, Globus GSI, gLite VOMS and Shibboleth. It enables users rapid and secure collaboration

Decision-Making for Automated Vehicles Using a Hierarchical Behavior-Based Arbitration Scheme

Behavior planning and decision-making are some of the biggest challenges for highly automated systems. A fully automated vehicle (AV) is confronted with numerous tactical and strategical choices. Most state-of-the-art AV platforms implement tactical and strategical behavior generation using finite state machines. However, these usually result in poor explainability, maintainability and scalability. Research in robotics has raised many architectures to mitigate these problems, most interestingly behavior-based systems and hybrid derivatives. Inspired by these approaches, we propose a hierarchical behavior-based architecture for tactical and strategical behavior generation in automated driving. It is a generalizing and scalable decision-making framework, utilizing modular behavior blocks to compose more complex behaviors in a bottom-up approach. The system is capable of combining a variety of scenario- and methodology-specific solutions, like POMDPs, RRT* or learning-based behavior, into one understandable and traceable architecture. We extend the hierarchical behavior-based arbitration concept to address scenarios where multiple behavior options are applicable but have no clear priority against each other. Then, we formulate the behavior generation stack for automated driving in urban and highway environments, incorporating parking and emergency behaviors as well. Finally, we illustrate our design in an explanatory evaluation

Progress on a generalized coordinates tensor product finite element 3DPNS algorithm for subsonic

A generalized coordinates form of the penalty finite element algorithm for the 3-dimensional parabolic Navier-Stokes equations for turbulent subsonic flows was derived. This algorithm formulation requires only three distinct hypermatrices and is applicable using any boundary fitted coordinate transformation procedure. The tensor matrix product approximation to the Jacobian of the Newton linear algebra matrix statement was also derived. Tne Newton algorithm was restructured to replace large sparse matrix solution procedures with grid sweeping using alpha-block tridiagonal matrices, where alpha equals the number of dependent variables. Numerical experiments were conducted and the resultant data gives guidance on potentially preferred tensor product constructions for the penalty finite element 3DPNS algorithm

Some remarks on the culture management in Poland : as of year 2013

Tekst stawia proste pytania: o związki kultury z zarządzaniem, a w konsekwencji pytanie o tożsamość zarządzania w kulturze. Pokazuje także, jakie problemy i dylematy towarzyszyły tworzeniu tej dyscypliny akademickiej w Polsce. Wskazuje na realia, w jakich zarządza się w Polsce kulturą, objaśnia sens i konieczność badań w tym obszarze, m.in. po to, by móc wypracować sensowny model polityki kulturalnej.In the text there are a few simple questions: what are the links between culture and management, and what culture management really means. The author also shows problems and dilemmas associated with the process of creating new academic field - culture management - in Poland. He describes realities of the situation, in which culture functions in Poland and explains importance and necessity of academic research in that area, with the intention of creating the base for solid model of cultural policy

Effect of low level laser therapy on migration of human skin cells across a standardized wound

The purpose of this study was to examine the effects that different dosages of low level laser therapy have on human skin cell migration. Normal newborn foreskin fibroblasts were seeded into a four well chamber microscope slide. Cellular monolayers were inflicted with three standardized wounds per well. Following the wounding of cells, each well received low level laser therapy once from a 635 nm laser at one of four treatment dosages (0.0 J/cm 2, 1.0 J/cm2, 1.5 J/cm2, 2.0 J/cm 2) with a power output of 11.5 mW. Digital images were recorded immediately following wounding, and every hour thereafter for seven hours. A cutting and weighing technique provided values for a percentage of wounded area present in each image. A mixed model ANOVA indicated that there was no significant difference in migration rates for cells treated with different dosages. Using LLLT with the tested parameters is no different than doing nothing at all

The Background and Experiences of the French Creek College Community Band Members: A Case Study

The purpose of this study is to increase understanding regarding the context of sustained music making for adult members of the French Creek Community College Band (FCCCB). Research questions included: 1. How do the participants’ backgrounds relate to their continued interest in music making? 2. In what ways do the ensemble structures and procedures respond to the musical and social needs of its members? 3. In what ways do individual participants contribute to the ensemble milieu? 4. By continuing their membership with the ensemble, what unique benefits do participants report? Data were collected from French Creek Community College Band participants through questionnaires, interviews with six participants, recordings of three rehearsals, five observation forms, and field notes taken during rehearsals at the time of this study. The following topics were identified as significant findings resulting from this study: the presence of diversity in the backgrounds and current experiences of ensemble participants, the importance of word of mouth impacting the structure and procedures of the FCCCB, the role of after-rehearsal dinners in building camaraderie and member advocacy, and the need for directors to be sensitive to the emotional needs of band participants contributing to eudaimonia among members.Master of Fine Arts (MFA)Music EducationUniversity of Michiganhttps://deepblue.lib.umich.edu/bitstream/2027.42/156019/1/Orzechowski_Thesis_6-23-20.pd
