Aligning thousands of images from serial imaging techniques can be a cumbersome task. Methods ([2, 11, 21]) and programs for automation exist (e.g. [1, 4, 10]) but often need case-specific tuning of many meta-parameters (e.g. mask, pyramid-scales, denoise, transform-type, method/metric, optimizer and its parameters). Other programs, that apparently only depend on a few parameter often just hide many of the remaining ones (initialized with default values), often cannot handle challenging cases satisfactorily. Instead of spending much time on the search for suitable meta-parameters that yield a usable result for the complete image series, the described approach allows to intervene by manually aligning problematic image pairs. The manually found transform is then used by the automatic alignment as an initial transformation that is then optimized as in the pure automatic case. Therefore the manual alignment does not have to be very precise. This way the worst case time consumption is limited and can be estimated (manual alignment of the whole series) in contrast to tuning of meta-parameters of pure auto-alignment of complete series which can hardly be guessed.

In this paper, we presented a logistic regression model that we applied for assessment of the users’ quality of experience with web browsing service over mobile network. With this regard, we chose the Average-Time-to-Connect-TCP network service quality parameter as an independent predictor, obtained by passive monitoring of live traffic data, captured by a passive probe on the mobile network Gn interface, and related to detailed records of the Transport Control Protocol. In parallel with in-service measuring the selected network parameter, we conducted simultaneous subjective tests of the quality of experience acceptability to users, specifically for web browsing service. Particularly, it was found that the model provided correct acceptability classification in 84.5% of cases, while reducing the chosen independent predictor for 100 ms implied increasing the chance of the service acceptability by factor of 1.65. Based on the obtained results, it comes out that the applied logistic regression model provides satisfactory estimation of the web browsing service quality experience acceptability.

Management literature proposes several broad categories of business motives behind Knowledge Management (KM) initiatives: minimising risk, improving efficiency and effectiveness and enabling innovation. While risk minimisation and efficiency and effectiveness improvement are fundamental for organisational survival, innovation is the key for organisational advancement and long-term economic success. Choosing the right KM strategy is of utmost importance for organisational performance. On the one hand, two popular Knowledge Management strategies termed codification and personalisation differ in their reliance on technology or people. On the other hand, two strategies referred to as exploitation and exploration differ in their focus on transferring existing or developing new knowledge. This study aims to examine the main business forces in KM adoption and to identify preferred KM strategies responsively. More specifically, it aims to provide a metric in determining (1) applied and realised KM strategies, (2) business focus, (3) knowledge processes and (4) knowledge focus. Data, collected from 372 surveyed employees of Turkish organisations across different industries, were analysed in terms of the two key classes of KM drivers and strategies. The findings reveal a widespread tendency for simultaneous pursuance of dual survival and advancement business goals and widespread integration of codification and personalisation as well as exploitation and exploration strategies. The findings validate the ability of Turkish firms in the organisation of KM activities through the combination of somewhat contradictory drivers and strategies implying their ambidexterity regarding considered KM strategies.

Quem sao os bebes? Essa e tantas outras perguntas instigaram o trabalho realizado com os bebes em tres creches municipais. Trata-se de um projeto vinculado ao PIBID - Programa Institucional de Bolsa de Iniciacao a Docencia. Nele foram organizados diferentes contextos educativos no intuito nao apenas de instigar a curiosidade, fantasia, imaginacao e inventividade dos bebes, potencializando suas experiencias, mas, tambem, instigar a propria curiosidade dos(as) estudantes, educadores(as) e pesquisadores(as) acerca dos bebes e suas producoes culturais. Como resultado foi possivel repensar a docencia com os bebes tendo-os como interlocutores privilegiados na construcao de uma pratica pedagogica dialogica, o que exigiu dos(as) adultos(as) silenciarem-se para entao escuta-los e com eles tambem aprender.
