Laboratory Development

Development of remote laboratory for embedded systems complex hardware/software design is an actual task, because the challenges existing in this area, require qualitatively new techniques, technologies and tools of design. By using the possibilities of remote labs and reusable hardware/software components, developer can more optimally organize the project and realize it in a shorter time. Development and usage of remote labs for designers can give new opportunities and ways for accumulation and study of existing design experience and ready solutions. On the other side, today, in the area of remote laboratories development are no common standards and approaches. Different developers offer different solutions for laboratory functionality, interfaces, a set of experiments, etc. At the same time, there are a number of ready-made solutions that can be used repeatedly for more optimal development and rapid integration with existing projects. Therefore, investigation and implementation of re-use methodology and its practical realization is an urgent task. The paper presents the structural components and API of remote laboratory RELDES, proposed for reuse in other projects for creation of mobile applications, new clients or services. Open questions of RESTful API documenting are also discussed.

Partitioning and allocating of software components are two important parts of software design in distributed software engineering. This paper presents two general algorithms that can, to a limited extent, be used as tools to assist in partitioning software components represented as objects in a distributed software design environment. One algorithm produces a partition (equivalence classes) of the objects, and a second algorithm allows a minimum amount of redundancy. Only binary relationships of actions (use or non-use) are considered in this paper.

Aperiodic Crystals

2014 is the International Year of Crystallography. During at least fifty years after the discovery of diffraction of X-rays by crystals, it was believed that crystals have lattice periodicity, and crystals were defined by this property. Now it has become clear that there is a large class of compounds with interesting properties that should be called crystals as well, but are not lattice periodic. A method has been developed to describe and analyze these aperiodic crystals, using a higher-dimensional space. In this lecture the discovery of aperiodic crystals and the development of the formalism of the so-called superspace will be described. There are several classes of such materials. After the incommensurate modulated phases, incommensurate magnetic crystals, incommensurate composites and quasicrystals were discovered. They could all be studied using the same technique. Their main properties of these classes and the ways to characterize them will be discussed. The new family of aperiodic crystals has led also to new physical properties, to new techniques in crystallography and to interesting mathematical questions. Much has been done in the last fifty years by hundreds of crystallographers, crystal growers, physicists, chemists, mineralogists and mathematicians. Many new insights have been obtained. But there are still many questions, also of fundamental nature, to be answered. We end with a discussion of these open questions.

Definition Of

IntroductionAn increased or disturbed activation and aggregation of platelets plays a major role in the pathophysiology of thrombosis and haemostasis and is related to cardiovascular disease processes. In addition to qualitative disturbances of platelet function, changes in thrombopoiesis or an increased elimination of platelets, (e. g., in autoimmune thrombocytopenia), are also of major clinical relevance. Flow cytometry is increasingly used for the specific characterisation of phenotypic alterations of platelets which are related to cellular activation, haemostatic function and to maturation of precursor cells. These new techniques also allow the study of the in vitro response of platelets to stimuli and the modification thereof under platelet-targeted therapy as well as the characterisation of platelet-specific antibodies. In this protocol, specific flow cytometric techniques for platelet analysis are recommended based on a description of the current state of flow cytometric methodology. These recommendations are an attempt to promote the use of these new techniques which are at present broadly evaluated for diagnostic purposes. Furthermore, the definition of the still open questions primarily related to the technical details of the method should help to promote the multi-center evaluation of procedures with the goal to finally develop standardized operation procedures as the basis of interlaboratory reproducibility when applied to diagnostic testing.

Most of currently existing laboratory servers of remote labs were built fully or partially with LabVIEW programming language from National Instruments. While proving to be the best tool for fast development of excellent SCADA and data acquisition applications, it appeared to be inadequate when it comes to deploying an application to the web. This paper will analyze the tools that can be used for accomplishing this task in the remote laboratories. Various National Instruments and third parties technologies will be compared. It will be shown that LabVIEW application serving as laboratory server can easily be deployed on the standard pluginless web-page without any modifications in LabVIEW code with WebPager.

In this article, we present ppmlhdfe, a new command for estimation of (pseudo-)Poisson regression models with multiple high-dimensional fixed effects (HDFE). Estimation is implemented using a modified version of the iteratively reweighted least-squares algorithm that allows for fast estimation in the presence of HDFE. Because the code is built around the reghdfe package ( Correia, 2014 , Statistical Software Components S457874, Department of Economics, Boston College), it has similar syntax, supports many of the same functionalities, and benefits from reghdfe‘s fast convergence properties for computing high-dimensional leastsquares problems. Performance is further enhanced by some new techniques we introduce for accelerating HDFE iteratively reweighted least-squares estimation specifically. ppmlhdfe also implements a novel and more robust approach to check for the existence of (pseudo)maximum likelihood estimates.

This article introduces a module for presenting interactive learning resources for kids in online and mobile environments. Traditional e- Learning systems are not suitable for children in preschool age, as they do not provide specific functionalities to meet the audience's presentation, interaction and focus requirements. To solve this problem, we propose a set of interactive software components for creating and visualizing lessons for kids, which can be integrated in existing and new e- Learning platforms and mobile applications. The article describes the challenges of using learning management systems, points out the needs of the specific audience, and finally reveals the functionalities of a module for realizing learning resources for kids.

Abstract Mobile applications are suitable as a structural possibility for students beginning their studies. Using the app Reflect.UP, students are encouraged to reflect on the organization, contents, and objectives of their studies. This article focuses on how students can acquire the academic ability to consider their own actions, which is an intrinsic component of academic professionalization. The work examines how a competency framework is derived through study regulations and module descriptions, and how subsequent questions for students’ reflection are systematically created using this framework. Next, the hybrid mobile application Reflect.UP and its underlying software components are introduced, stimulating students’ reflections on study content and objectives. The data gathered through the practical use of Reflect.UP is evaluated, and then the ensuing conclusions drawn from students’ problems and learning processes for organizing the course of studies are explored. In addition, this paper reflects on the strengths and weaknesses of a mobile application as a sociological and technological compound for structural support of the introductory phase of education.
