Modular fastening system and tool–holder working unit for incremental forming
2019
Incremental forming can be usually unfolded either on CNC milling machine–tools or serial industrial robots. The approach proposed in this paper tackles the problem of designing a modular fastening system, which can be adapted for both above mentioned technological equipment. The fastening system of the sheet–metal workpiece is composed of a fixing plate and a retaining plate. The fixing and retaining plates will be made up of different individual elements, which can be easily repositioned to obtain different sizes of the part. Moreover, the fastening system has to be able to be positioned either horizontally (to be fitted on CNC milling machines) or vertically (to be fitted on industrial r…
The benefits of inclusive education: new challenges for university teachers
2017
Inclusive education is a child’s right, not a privilege. The amount of current attention given to children and to childhood is unprecedented. In a world affected by financial crises, attitudes about children’s needs are very important. Recent years have seen innovations in the focus of research, as political moves that challenge the ways different children have been excluded and silenced. Inclusive education is a real and urgent need for all educational systems around the world. Inside our university, the Teachers Training Department needs to take serious measures to create a professional environment for all the students involved in the initial training for becoming teachers at all levels. …
Alignment between standardized assessments and academic standards: The case of the Saber Mathematics Test in Colombia
2013
In this study the concept of alignment is analyzed by presenting the results of a study that examines the degree of alignment between a standardized mathematics assessment and a set of academic standards. The alignment was examined using the Webb model and the results suggest that the degree of alignment between standardized assessments and academic content standards is not the most appropriate and therefore the results should be interpreted with great caution and stakeholders must be very careful with the type of decisions that are made based on the results of these types of assessments.
Valencian Network of Educational Innovation in Optics
2014
[EN] The Valencian Network of Educational Innovation in Optics consists of three groups from the Universitat de València, Universitat Jaume I, and Universitat Politècnica de València. The participants in the network present an extensive background on performing actions to improve teaching practice. They have been involved for years in scientific outreach activities and in a number of educational innovation projects, which have developed innovative teaching materials. With the aim of sharing their experience and enhance their performance, the three groups have decided to join forces to become a Network of Educational Innovation whose main projects are described in this communication.
Considerations on the automation of a natural gas compressor station
2018
Natural gas compressor stations are very important components of a natural gas life cycle. Unfortunately, in Romania most of the existing natural gas compressor stations are equipped only with old-type automation systems, with a high degree of physical and moral wear. The current paper describes the main elements and functions of an automation system that was implemented in a natural gas compressor station, offering an improved pressure control function, but also the possibility to control the compressors from a distance, for example from a central dispatching station.
Reinforcement Efficiency of Cellulose Microfibers for the Tensile Stiffness and Strength of Rigid Low-Density Polyurethane Foams
2020
Rigid low-density closed-cell polyurethane (PU) foams are widely used in both thermal insulation and structural applications. The sustainability of PU foam production can be increased by using bio-based components and fillers that ensure both enhanced mechanical properties and higher renewable material content. Such bio-based foams were produced using polyols derived from rapeseed oil and microcrystalline cellulose (MCC) fibers as filler. The effect of MCC fiber loading of up to 10 wt % on the morphology, tensile stiffness, and strength of foams has been evaluated. For estimation of the mechanical reinforcement efficiency of foams, a model allowing for the partial alignment of filler fibers…
The impact of the age of vines on soil hydraulic conductivity in vineyards in eastern Spain
2017
Soil infiltration processes manage runoff generation, which in turn affects soil erosion. There is limited information on infiltration rates. In this study, the impact of vine age on soil bulk density (BD) and hydraulic conductivity (Ks) was assessed on a loam soil tilled by chisel plough. Soil sampling was conducted in the inter row area of six vineyards, which differed by the age from planting: 0 (Age 0; just planted), 1, 3, 6, 13, and 25 years (Age 1, Age 3, Age 6, Age 13, and Age 25, respectively). The One Ponding Depth (OPD) approach was applied to ring infiltration data to estimate soil Ks with an α* parameter equal to 0.012 mm-1. Soil bulk density for Age 0 was about 1.5 times greate…
QUALITY PARAMETERS OF DAIRY WASTEWATER IN THE MUREŞ COUNTY, ROMANIA
2017
The objective of this study was to investigate the main quality indicators of wastewater in a dairy factory located in Mureş County, with a water treatment plant built recently. The wastewater samples were tested for extractable matter, total suspended matter, fixed residue, biological oxygen demand, chemical oxygen demand, total suspended solids and pH values. The results indicated that pollution levels of wastewater samples tested were found high. This means that the method of treatment does not have the necessary effectiveness that can cause high load of effluent in NH4+, total suspended solids, Chemical Oxygen Demand - COD-Cr, Biochemical Oxygen Demand - BOD5, pH for dairy wastewater fr…
Computer-assisted preparation in conference interpreting
2017
Preparation has been proposed in the literature as one of the most important phases of an interpreting assignment, especially if the subject is highly specialised. Preparing an assignment in advance aims at bridging the linguistic and extra-linguistic gap between conference participants and interpreters and at reducing the cognitive load during interpretation. For these reasons it is considered crucial in ensuring higher interpreting quality. Yet, preparation is generally time-consuming and interpreters may often experience the feeling of not knowing exactly how to perform this task efficiently. Information technology could change this. Even though the first computer-assisted interpreting s…
Revista electrónica de investigación y evaluación educativa
2010
The aim of this work is the development of a model that can be used as a framework for evaluators and PhD tribunal members, either during the previous administrative processing phase or at the actual exposition and viva on doctoral dissertations. To this end, once reviewed the existing literature and normative, a new proposal is laid out on the main aspects and criteria to be analysed and assessed from any given scientific work, thus introducing a tool that facilitates and specifies this work. Our model is intended to be an open proposal on which we would welcome any contribution and suggestion. El objetivo del presente trabajo es la elaboración de un modelo que pueda ser utilizado como mar…
