Fluid rigid body interaction is commonly occurring phenomenon and this phenomenon is of high importance in many engineering applications. The main objective of the present paper is to analyse vibrations due to fluid-rigid body interactions by inclining the frontal area of flat plate to flow. As understood from the existing research, the main challenge is the understanding of non-stationary fluid body interactions. Interaction analysis, optimization and synthesis tasks include space-time programming methods and approximate analytical methods. This article discusses an approximate analytical method in which the object's interaction with fluid flow is divided into two parts in the fluid body interaction space. The first part is the frontal pressure side that arise as a result of change of momentum in the system that can be conveniently represented in a differential form. The second part includes the idea of describing the interaction behind the plate as a certain thin (vacuum) side was accepted. This thin vacuum side also depends on the frontal area flow interaction. The use and precision of the approximate analytical method was verified by experiments in the wind tunnel. The method was used for good analysing of varying frontal area (until flattening) of flat plate in fluid flow. The main parameters for motion excitation are the changes in plate-flow interaction area, velocity and angle of inclination of the flat square plate to the fluid flow. Experiments were performed at 10 m•s-1 keeping in view the wind speeds that were observed in the past in Riga, Latvia.
The paper deals with establishment, implementation and development of electronic prescription or e-Prescription in context with e-Health solutions. It includes introduction of a numerous innovative solutions, which are to be committed for data information flow, data management and functionality as well as of establishment of a new feasible communication forms between doctors, patients and pharmacists. The aim of the study is to describe some technical aspects and functionality of implementation of e-Prescription system for medical institutions, patients and pharmacies; and, calculation of the total cost of implementation (TCI) for Latvian individual pharmacies. Several expecting financial aspects, which have encompassed evaluation of TCI, calculating payback time, ROI, NPV, and IRR are to be calculated. On the bases of these financial calculations, the primary investment of implementation of e-Prescription for individual pharmacies and initial costs are determined. Impact on individual parts of TCI with the scope to individual pharmacy size, location, existence or absence of formal information strategy has calculated. According to collected data, research paper shows how proposed electronic system is going to implement among Latvian individual pharmacies.
EPICES is an Erasmus plus strategic partnership project (September 2014 – August 2016) co-funded by the EU. There are seven academic partners and one association engaged in this project. The purpose of EPICES is to develop a European collaboration on at-a-distance project-based learning framework and method, based on already existing and still developing technical platforms, i.e. collaborative and engineering tools. A special focus will be made on teachers’ role and students’ coaching, from the analysis of what a coach should be in project based learning to training packages for teachers and development of assessment methods. This focus is a key issue to be discussed in order to develop project based learning for engineer students, especially in international and/or industrial context, which requires strong and effective collaboration of all actors to succeed and innovate within the project based learning framework. In EPICES, sub-projects are developed, which place students in the middle of real industrial European at a distance projects, i.e. in the heart of the future job of every current engineer student. These sub-projects are study cases, study materials, and allow many feedbacks and intellectual outputs on coaching, teachers’ role and assessment issues. Since its beginning, EPICES has gained in maturity and in this work-in- progress the objective is to present the first achievements of three intellectual outputs: establishing a model of facilitator roles and skills in project-based learning in European engineering education; studying teacher facilitation in preparation for training of teacher, creating assessment methodology for project- based learning in engineering studies and development of tools for assessment of skills
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
