Networks with local inhibition are shown to have enhanced computational performance with respect to the classical Hopfield-like networks. In particular the critical capacity of the network is increased as well as its capability to store correlated patterns. Chaotic dynamic behaviour (exponentially long transients) of the devices indicates the overloading of the associative memory. An implementa...
The use of social media has become popular in the professional IT sector, requiring specific skills to exploit their full potential. Based on our model on relevant social media skills we report on a study testing related proficiencies of IT vocational students. From this we derive three technology-enhanced training instruments to foster the skills in vocational education processes.
Recent attention on the potentiality of cost-effective infrastructures for capturing and processing large amounts of data, known as Big Data has received much attention from researchers and practitioners on the field of analytics. In this paper we discuss on the possible benefits that Big Data can bring on TEL by using the case of large scale comparative assessments as an example. Large scale c...
In this paper we study one feedback process which is adapted to ill-defined domains. Indeed, this process use others aspects than expected solutions to propose a feedback. The feedback process is based in a set of didactical aspects. In particular, the feedback targets the control element of knowledge, i.e. the knowledge that allows to validate one step in the problem solving process. The paper...
The swing of the pendulum between centralization and decentralization of the higher education (HE) system has generally been towards the former in the Iranian context in the past decade. This has prompted some academics, particularly those who find their disciplines left out to react by highlighting intrinsic differences in teaching and studying methods across the HE spectrum. Built Environment...

Dehydrohalogenation of 5,6-dihalogen-1,3-dioxepanes II with KOH/MeOH or NaOCH3/MeOH under controlled reaction conditions gave mainly 5-halogen-4,7-dihydro-1,3-dioxepines III. Further substitution of vinylic-bromine in III whit KO-t-Bu/tert-BuOH or KOH/MeOH led to corresponding 5-substituted-4,7-dihydro-1 ,3-dioxepines some of which underwent spontaneous isomerization to 6,7-dihydro-1,3-dioxepin...
