Contribution: From the moment when universities began to talk about learning environment instead of classes and schools , a summative notion that entails knowledge transfer heralds an important stage of redefining the basic elements of learning. A learning environment requires the transition from learning rounding off toward open learning, without the limitations of time and space. Background: In this context, the present work attempts to examine the role of an instrument, namely, remote experiment (RE), and its application to draw attention to the pedagogical complexity embedded by this new experiential learning tool. Intended Outcomes: The objective is to prove that the transition from classical education with a defined location and geographical separation, to a modern e-learning education occurs by using the RE that contains all forms of knowledge. In addition, the operation tacitly and explicitly knowledge augments the importance of RE in applicative education as well as the didactic results in line with the industry requirements. Application Design: The convergent analysis method was used and emphasized the divergent content of knowledge acquired through the use of RE that is replete with a great creative potential. Findings: It is shown that its usage (a mix between software, hardware, and pedagogy) manages to address the students’ concerns through all ranges of knowledge that falls under a well-organized teaching system, can call. This underscores the importance of embedded knowledge that can expand students’ knowledge area in a happy manner.

Music is important in everyday life, and music therapy can help treat a variety of health issues. Music listening is a technique used by music therapists in various clinical treatments. As a result, music therapists must have an intelligent system at their disposal to assist and support them in selecting the most appropriate music for each patient. Previous research has not thoroughly addressed the relationship between music features and their effects on patients. The current paper focuses on identifying and predicting whether music has therapeutic benefits. A machine learning model is developed, using a multi-class neural network to classify emotions into four categories and then predict the output. The neural network developed has three layers: (i) an input layer with multiple features; (ii) a deep connected hidden layer; (iii) an output layer. K-Fold Cross Validation was used to assess the estimator. The experiment aims to create a machine-learning model that can predict whether a specific song has therapeutic effects on a specific person. The model considers a person’s musical and emotional characteristics but is also trained to consider solfeggio frequencies. During the training phase, a subset of the Million Dataset is used. The user selects their favorite type of music and their current mood to allow the model to make a prediction. If the selected song is inappropriate, the application, using Machine Learning, recommends another type of music that may be useful for that specific user. An ongoing study is underway to validate the Machine Learning model. The developed system has been tested on many individuals. Because it achieved very good performance indicators, the proposed solution can be used by music therapists or even patients to select the appropriate song for their treatment.

The paper presents the results of the fatigue testing of heat-treated and thermochemically treated C75 steel with different process parameters in terms of working medium (gas, salt bath), temperature, and time. The experimental program aims to analyze the changes in microstructure under the influence of heat treatment and fatigue resistance. The relationships between the structural changes, the internal stress, and the heat-treated material’s mechanical and physical properties can determine the first nano cracks leading to rupture propagation. Based on the experimental values of this paper, we highlight the dependence between the nature of the cracks and the stress to which the specimen was subjected. The paper presents a brief introduction to the fatigue test and the experimental tests performed to determine the fatigue resistance characteristics, the macroscopic analysis of the material, and the crystallographic analysis. The results obtained allow a comparison between the fatigue limits of heat-treated and thermochemically treated C75 steel in gas and salt baths.

A study conducted by the World Economic Forum revealed that about 75 million jobs will disappear because of the Artificial Intelligence (AI), but AI will bring with it more than 133 million new job. Therefore, for making a smooth transition to the next Industrial Revolution, the reskilling initiatives play a key role. In the information age, it is crucial to educate students to acquire the skills necessary for the new jobs that will be created thanks to AI. Because everything we touch and everything we do will be enhanced by AI in the near future, new ways of working will become increasingly popular. Therefore, this paper aims to define new learning methods based on AI to educate engineers for the jobs that will emerge in the following years.

In this paper we introduce a model of cooperation between High School-University-Industry sustained by activities and results obtained in “Cypress – National Instruments Club” started at “Transilvania” University of Brasov – Romania. This strategic collaboration between High School-University-Industry was become necessary because technology is evolving at a rate that is quickly outpacing traditional engineering teaching methods. New methods such as hands-on learning labs, industry-centric curriculum, permanent updating of facilities, and using new adaptive learning software are being adopted. “Transilvania” University is targeting education at the industries of the future rather than industries of the past and for this reason we must apply the same strategies inside the high school in order to well prepare the children’s, future students and the new engineers.

The goal of V2V Vehicle-to-Vehicle communication is to prevent accidents by allowing vehicles in transit to send position and speed data to one another over an ad hoc mesh network. Depending upon how the technology is implemented, the vehicle’s driver may simply receive a warning should there be a risk of an accident or the vehicle itself may take pre-emptive actions such as braking to slow down. V2V technology represents the next great advance in saving lives. This technology could move us from helping people survive crashes to helping them avoid crashes altogether—saving lives, saving money, and even saving fuel thanks to the widespread benefits it offers

Our Research has shown that in universities there is no unified strategy to support intellectual processes related to creativity. Since 1998, Teresa Amabile stressed the link between the work environment and creativity. Her research meant “workplace creativity”. We wondered whether the principles of work underlined by the Amabile cannot apply to the organization called the University and if so, what are the particularities to be taken into account so that the university system becomes a kind of antechamber of preparation of graduates with these “finished” and “awakened” qualities for the entry into the creative environment offered by the organizations of the economic environment. For the curriculum, reformed in terms of the support of the creativity, are listed some design principles (the main ones) that are the catalyst for creativity. It’s about Fluency, Originality, Flexibility and Elaboration. The Analysis in the paper also assumed a parallel look of instructionism with profound learning. The Bottom line is that the instructionism practiced on a large scale today only accidentally leads to creativity. There are considerations regarding the binomial “part – whole” and the way his approach can annihilations or encourage creativity. It is brought as an argument for the reform of the Science of Complexity which gives us the ability to redesign the curriculum “learning by discovery” and “learning by direct implications in experimental projects”.

Many actual developments in mobile learning deal with “Remote Laboratories”. The development of different electronics kits and the decrease in their price lead directly and easily to the idea of “student home labs” and empowered the idea of “learning by doing”. Following discussions with many students we reached the idea of developing myDAQ Micro-Modular units able to be implemented in university laboratories or even by students in their homes. We started to develop and implement some easy to build and low price Micro-Modular devices for myDAQ (and/or myRIO) controlled by simple LabVIEW applications. These devices will be tested and developed during the next semester at the 2nd year bachelor students within the Electronics Measurement Laboratories.

We fabricate Si nano-grating layers and measure their electrical characteristics to monitor geometry induced doping. SOI device layer was thinned down by thermal oxidizing and subsequent wet etching of the oxide. Grating was fabricated using laser interference lithography (375 nm laser) followed by reactive ion etching of Si. Next, large square island (0.5x0.5 mm) was shaped in the device layer and four Si\Ti\Ag ohmic contacts were formed to measure electrical characteristics. The I-V characteristics were recorded using both 4 wire and 2 wire methods. Resistance-temperature dependences (T= 4-300 K) were recorded as well. For all 12 samples, nano-grating layers show 2-3 order reduction of resistivity. Resistivity anisotropy was in the range 0.2-1 at 300 K. Obtained geometry induced doping level corresponds to “effective impurity” concentration of 3x10 18 cm -3 . The dependence is in agreement with G-doping theory only below T=150K.

In recent years, education talks have shifted from the areas: “classes,” “schools”, “universities” to the “learning environment”. This is because the Internet has introduced “virtual environment” into education. The map of study places has been significantly changed, adding to temporal, spatial and geographical learning, learning in an environment without geographical and temporal boundaries. The term “learning environment” now includes the classes, schools and universities we are talking about above, but also the virtual environment with its own classes, schools and universities, or other forms of education that have not been seen before (e.g. MOOC’s). This process has determined a strong modification of the current teaching theories of learning.

In Transylvania's University — Creativity Laboratory we try to do complex trainings of students and high school children's — connected with the their preparation for LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench) Academy examinations. The graphical nature of LabVIEW makes it easier to develop working code faster — quickly drag and drop built-in functions to simplify acquisition, analysis, control, and data sharing so you can spend less time on syntax errors and more time on creative development of your application. In this paper we present how we put together: industrial cooperation (developed in cooperation with industry), complex system development and fast implementation, LabVIEW training and student/children's creativity development (learning by doing). It is a good exercise to increase creativity starting from a concrete application that allows multiple solutions. This diversity allows students to compare, to do critically appreciation one another, to understand the role of communication and exchange of experience in creating new solutions and to have finally the satisfaction of one achievement, made by their own, under the guidance of professor and in collaboration with colleagues.

Today, many theories of learning work in parallel. Each of these theories contains valuables notions useful in knowledge transfer but, unification efforts are weaker than efforts to create new concepts of learning. Recently, the powerful involving of technology (Internet, remote experiment, learning platforms, etc.) in teaching and learning led to a regrouping of the concepts regarding the transfer and acquisition of knowledge. One point of view regarding this process is presented in this paper. It is speaking about an independent combination between Bloom's taxonomy and applications and possible correlations with Kolb s learning model. Each theory contains irrefutable truths and simultaneously neglects important issues of the process. An attempt to build a correspondence between these two models shows that: • Teaching is a combination of theory and practical experiments, what usually are called courses for “knowledge transfer”. Today is generally accepted that the sum of courses contained in a curriculum adequately prepares the student for the future career; • Charts Rigor-Relevance however shows that the stage of “applications across disciplines” brings closer the student to the real life; • The same diagram shows that in teaching environment the applications located in unpredictable environment lead to the formation of skills closer to the real career problems; The question is whether the Kolbs experiential learning cycle has the same conclusions as Rigor-Relevance, especially since it considers learning starting from experiment not from knowledge. The paper reconsiders the cycle of Kolb theory content and shows that each of the four stages, which this cycle passes, contains obviously both elements from the taxonomy of Bloom and the possibility to organize experiments passing successively from those that are required for a single discipline towards the experiments across disciplines under predictable and unpredictable conditions.

The paper presents research regarding the complex behavior of materials based on Si and SiO2, geometrically processed at nano-scale. The geometry, which induces the doping effect (G-doping), occurred when it was possible to fabricate nanograting structures. Studies on the influence of nanograting structures on the properties of materials have shown that this process may lead to effects similar to those created by doping with donors. The resistivity values measured in Si-based nanograting layers, for example, were approximately 10-2 Ω cm, similar to those of Si semiconductors doped with phosphorus 'impurities' having a volume concentration of 1018 cm-3. This increase in electronic properties, as a result of the nanograting structure, seems to appear due to the fact that the electrons rejected in the process are placed in the structure vacancies. It has been experimentally proven that, in the case of semiconductors, the nanograting structuring makes the rejected electrons from the valence band to be placed in the conduction band. In the paper, after samples fabrication with nanograting structures on Si films placed on SiO2 support, the I-V curves of the obtained layers were drawn, both by measuring in four points and also in two points. The resistivity measurements were made in two directions: along and perpendicular to the strips of the structure and showed the existence of an anisotropy.

In manufacturing processes involving diffusion (of C, N, S, etc.), the evolution of the layer depth is of the utmost importance: the success of the entire process depends on this parameter. Currently, nitriding is typically either calibrated using a “post process” method or controlled via indirect measurements (H2, O2, H2O + CO2). In the absence of “in situ” monitoring, any variation in the process parameters (gas concentration, temperature, steel composition, distance between sensors and furnace chamber) can cause expensive process inefficiency or failure. Indirect measurements can prevent process failure, but uncertainties and complications may arise in the relationship between the measured parameters and the actual diffusion process. In this paper, a method based on noise and fluctuation measurements is proposed that offers direct control of the layer depth evolution because the parameters of interest are measured in direct contact with the nitrided steel (represented by the active electrode). The paper addresses two related sets of experiments. The first set of experiments consisted of laboratory tests on nitrided samples using Barkhausen noise and yieded a linear relationship between the frequency exponent in the Hooge equation and the nitriding time. For the second set, a specific sensor based on conductivity noise (at the nitriding temperature) was built for shop‐floor experiments. Although two different types of noise were measured in these two sets of experiments, the use of the frequency exponent to monitor the process evolution remained valid.

In this work we try to address the large interest existing nowadays in the better understanding of the interaction between microbial biofilms and metallic implants. Our aimed was to identify a new preventive strategy to control drug release, biofilm formation and contamination of medical devices with microbes. The transfer and printing of novel bioactive glass-polymer-antibiotic composites by Matrix-Assisted Pulsed Laser Evaporation into uniform thin films onto 316 L stainless steel substrates of the type used in implants are reported. The targets were prepared by freezing in liquid nitrogen mixtures containing polymer and antibiotic reinforced with bioglass powder. The cryogenic targets were submitted to multipulse evaporation by irradiation with an UV KrF* (λ = 248 nm, τFWHM ≤ 25 ns) excimer laser source. The prepared structures were analyzed by infrared spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy and profilometry, before and after immersion in physiological fluids. The bioactivity and the release of the antibiotic have been evaluated. We showed that the incorporated antibiotic underwent a gradually dissolution in physiological fluids thus supporting a high local treatment efficiency. Electrochemical measurements including linear sweep voltammetry and impedance spectroscopy studies were carried out to investigate the corrosion resistance of the coatings in physiological environments. The in vitro biocompatibility assay using the MG63 mammalian cell line revealed that the obtained nanostructured composite films are non-cytotoxic. The antimicrobial effect of the coatings was tested against Staphylococcus aureus and Escherichia coli strains, usually present in implant-associated infections. An anti-biofilm activity was evidenced, stronger against E. coli than the S. aureus strain. The results proved that the applied method allows for the fabrication of implantable biomaterials which shield metal ion release and possess increased biocompatibility and resistance to microbial colonization and biofilm growth.

The necessity to create virtual sensors derived from the fact that in the condition of the existence of millions of sensors, cloud computing becomes the compulsory layer between physical sensors which capture aspects of the external environment and the application interface. In fact a virtual sensor is able to measure indirectly, combining the data obtained from physical sensors, sizes that are not physically measurable. In this paper the authors analyze the implications of virtual sensors in the future development of the remote experiment. Virtual sensors will form a bridge between what is measured in the network and what learners will want to measure, using the existing sensors and an appropriate algorithm. Virtual sensors will convert data from multiple sensors into useful information that cannot be obtained from a single sensor, providing an indirect measurement of values that are not physically measurable. The introduction of the virtual sensors will multiply the communication manners, implying Machine to Machine (M2M), People to Machine (P2M) and People to People (P2P) [1].

A short view on the remote experiment in 2016 allows us to affirm that it represents: "an infusion of technology in learning environment" and also "the transformation of technology in catalyst of learning". After some years of the remote experiment implementation and its use as a new tool in teaching/leaning, we are able to notice that, together with e-learning, we assist at an important process regarding the movement of education process from "knowledge transfer" to a "mixture of blended, collaborative, and active with in-class model". The evolution of the digital reality, in this period of the remote experiment implementation, becomes so important that laws defined at the beginning as an exercise have been confirmed by reality, and start to have important effects. We are referring to: Moores' law: "…the number of transistors on integrated circuits doubles approximately every 18 months." [1]. The confirmation of the veracity of this law consists in the spectacular increasing of the processing speed and memory capacity. Neilsen's law: "…the connection speed increases by 50% per year." [1]. In education the effects of this law are not proportional because telecom companies — being conservative — act as a break, and because users do not want to spend much money on bandwidth. Edholm's law: "…the curve of growth of wireless connections is more rapid than wire-line growth.". Kryder's law: "…hard drive storage capacity doubles every 12 months in the case of HDDs and doubles every 18 months in the case of solid state storages." [1]. Metcalf's law: "…the physical cost of the network grows linearly when it increases while its value grows exponentially, being proportional with the square of the number of connected users.". In this landscape, remote experiment encapsulates the idea that laboratory work or industrial applications embedded with sensors and actuators, sustained with proper software and connected wirelessly to the Internet — improved the education system in terms of content, speed, cost and so on. At other angle of vision, this phenomenon might be considered as: massive integration of the physical world in cyber space.

In the last two decades digital technology has become an important part of everyday life. More than that, “digital technologies” have gained the status of “social community.” This paper presents the remote experiment argument between the concepts of “technological determinism” — which considers that culture is a passive element and technology the active element, and of “socio-economic determinism” — which considers that culture is an active element and technology the passive element. From this dichotomy the concept of “embedded determinism” has emerged. In this landscape remote experimentation as a part of digital creativity has changed the philosophy of laboratory works from — “imposing rigid rules” — proper for the “face-to-face” labs towards “freedom to create.” Remote experimentation (RE) as a new tool for teaching and learning in the virtual space introduced some new characteristics in the e-culture environment: • RE has led the change in the learning environment, putting the existing rules to the test; • Due to the ability to compare one experiment with another experiment created in another part of the world, mistakes are discovered quickly by the students, putting applied education in a glass house; • RE has moved the individual work towards community and cooperation in the network; • RE is a part of an e-world, characterized by decentralization and quite out of control. This aspect contradicts existing teaching and learning systems which are centralized; • RE introduced the dynamics of Internet into the education system. Some considerations regarding these ideas will be presented in the paper.

New Powerful Technologies enable fast development and increase the speed of information dissemination. When this is combined with the exponential growth of internet connectivity, it offers new challenges in Engineering Education. In view of this new paradigm, professors in universities together with students at many levels (high school, bachelor, master etc.), must act as one to strengthen their alliance with industry. In our Creativity Laboratory at the “Transylvania” University we formed a new and original alliance with Cypress Semiconductor and National Instruments to promote and develop applications using these powerful technologies. We involve all levels of education from high schools to the master degree based on this idea: Powerful Technologies Together for Engineering Education (PTT for EE). We believe that the marriage of PSoC programmable system-on-chip families, with a huge variety of data acquisition systems such as the LabVIEW graphical programming system, myDAQ, and myRIO along with Vizic Technologies new smart intelligent graphics processor units enable a compelling pedagogy to add color, visual, and touch interfacing to any application or project.

The rapid spreading of the remote experiment in general, and of the remote laboratory in peculiar, has oriented the main research efforts for software and hardware creation and neglected the pedagogically aspects of this field. In the paper the authors started from this above consideration. The first conclusion of a deep analyze was that the remote experiment is a new shape of the experiential learning. When Knob (1984) launched this concept, virtual environment for learning was not discovered so that is important to analyze the position of the remote experiment in Kolb's experiential learning theory. Paper presents some considerations in this respect. Also, in some paper [1], [2], [3], was sustained that the remote experiment has a great potential in creation of an environment able to nourish creativity potential of the students. Some considerations regarding remote experiment positioning in the Nonaka (1991) SECI (Socialization — Externalization — Combination — Internalization) concept are also made, resulting an original point of view that complete some pedagogical approaches of this new field. An attempt to combine Kolb and Nonaka concepts and to extract from this combination some rules for the remote experiment is made.

The paper analyses the gastric signal acquiring with electrodes, placed at few centimeters distance from the gastric tissue. The electrogastrography EGG was accurately extracted as invasive method, by penetrating needles into the stomach walls since 15 years ago. Relatively recent, a non-invasive method, based on skin electrodes on the abdominal region, was investigated as a remote organ test. The technical and medical particularities for the EGG signal recording are presented. The paper presents a versatile solution for the acquiring, filtering and processing of the cutaneous electrophysiological signal recording from the abdominal skin. Low-pass filters coupled to band pass filters are connected in order to abruptly cut higher frequencies than 50-25Hz and to allow the useful signal transmission. The data vectors are recorded by a specialized medical analog platform ADS1298 and transmitted to a mobile PC. This allows a subsequent digital signal processing, followed by a signal characterization.

Learning there is considered an individual activity. During the learning process we handle and manipulate knowledge in a physical way. It means that we working with “tangible” knowledge. Learning process there is realized in one physical environment and is recognized by all that it influences behavior (Gallagaher -1993) [1]. An important part of the learning is collaboration that introduced an important learning parameter: working environment. This environment allows to puts together thinking skills, communication skills, affective skills, all with the role to establish correlations between learning environment and external environment. The above remarks pointed that is beneficial to move learning from individual activity towards the collaborative, extending the internal environment towards external ones in some proportions. In the paper are mentioned some peculiarities of this movement when in learning process are implied the remote experiment as a new pedagogical approach.

Remote experiment and his quite recent extension towards remote experiment network have created a new workspace in teaching / learning environment. There is well known the fact that “environment influences behavior” (Gallagher -1993). Remote experiment has an articulated, codified and stored shape being easy to be transmitted to others. It means that remote experiment has all of the characteristics of tangible knowledge. In short, moving towards actually acceptations, remote experiment represents: “know-what” because it is referred at facts, represents: “know-why” because is connected at scientific understanding and also represents: “know - who” because implies networking. In the paper authors want to stress other additional characteristics of the remote experiment as teaching / learning environment. These additional characteristics will be launched as questions: - remote experiment succeed to fuse two important things - “thinking” and “doing”?; - remote experiment succeed to combine in a happy manner the two sides of brain activity: linear way (written texts) with nonlinear way (visual side)?; - the combination between linear and nonlinear ways will add as a new characteristic of the remote experiment the “visual thinking”? There is well known the path of knowledge production: the raw intangible knowledge is transferred with the help of the tangible in other tangible but, during this process, it is also transformed in supplementary internalized intangible knowledge at other level (Nenonen -2004) [1]. Also there is well known the Polany (1958) statement: “we can know more than we can tell” [3]. Paper will deals with above questions and statements because the development of the remote experiment in the last five years need some pedagogical clarifications in its sustainability and development. Intangible knowledge, named many times “know how”, is often difficult to be measured. But is possible to do indirect effects using the remote experiment, as a new workspace, that will improve the process of knowledge creation.

In the paper is discussed the changes in high education as an effect of the tendency of creation of those environment able to stimulate innovation and creativity. We consider that as a new pedagogy system in e-learning, remote engineering there is favorable system for creativity. It has some peculiarities which allow more easy TRIZ application.; Determine the unification of the language and English becomes dominant; The software used for remote labs are not so dispersed; Implies separation of the information process and training; TRIZ need self-education under external control and self-education implies acquiring knowledge and mastering skills for persons with strong motivation. Remote engineering allows not only solving, in original manner, the contradictions of some technical problems, but also produce an indirect effect. It means that students will meet the case of inversion: the group of trainers, best ones, will offer hers creations, to the each student, individually. With other words, the system trainer - group of students becomes group of trainers - one student, with strong influence in divergent thinking development.
