This paper presents Digital Habitats, a conceptual and methodological framework for analyzing and designing smart appliances in the context of pervasive computing. The concrete topic is a project in pervasive gaming for children. The framework consists of a set of theoretical concepts supplemented by diagrams for representing semi-formal models. We give a short overview of selected theories of play and gaming and apply the framework to an implemented simple pervasive game. Finally, we use the framework in a constructive man-ner to produce a concrete design of a new game. The result is dis-cussed and compared to other approaches. The main points are: (a) it can describe communicative as well as material acts plus the way they hang together, (b) it provides an explicit link between human activities and their spatial context, (c) it has an explicit dynamic model that pre-cisely describes the conditions for executing actions, and (d) it offers a typology of participant roles, based on linguistic theory, that supports design processes.

This chapter presents digital habitats, a conceptual and methodological framework for analyzing and designing smart appliances in the context of pervasive computing. The concrete topic is a project in pervasive gaming for children. The framework consists of a set of theoretical concepts supplemented by diagrams for representing semiformal models. We give a short overview of selected theories of play and gaming and apply the framework to an implemented simple pervasive game. Finally, we use the framework in a constructive manner to produce a concrete design of a new game. The result is discussed and compared to other approaches. The main points are the following: (a) it can describe communicative as well as material acts plus the way they hang together; (b) it provides an explicit link between human activities and their spatial context; (c) it has an explicit dynamic model that precisely describes the conditions for executing actions; and (d) it offers a typology of participant roles based on linguistic theory, which supports design processes.

The aerodynamic experimental set TRMS (Twin Rotor MIMO System) is a strong nonlinear system, which has been taken by many scientists as an object to test modern control algorithms. The paper built a complete and explicit dynamic model for the TRMS based on dissociating TRMS into 3 subsystems, using homogeneous transformations in orthogonal coordinate systems to calculate the mass point’s position and velocity in component sub-systems; Euler - Lagrange equation was applied to model the dynamics for the object. Keywords— TRMS, dynamics, homogeneous transformation, mechanical system dissociation, Euler - Lagrange.

Different Types

In the field of pervasive computing, wearable devices have been widely used for recognizing human activities. One important area in this research is the recognition of activities of daily living where especially inertial sensors and interaction sensors (like RFID tags with scanners) are popular choices as data sources. Using interaction sensors, however, has one drawback: they may not differentiate between proper interaction and simple touching of an object. A positive signal from an interaction sensor is not necessarily caused by a performed activity e.g., when an object is only touched but no interaction occurred afterwards. There are, however, many scenarios like medicine intake that rely heavily on correctly recognized activities. In our work, we aim to address this limitation and present a multimodal egocentric-based activity recognition approach. Our solution relies on object detection that recognizes activity-critical objects in a frame. As it is infeasible to always expect a high quality camera view, we enrich the vision features with inertial sensor data that monitors the users’ arm movement. This way we try to overcome the drawbacks of each respective sensor. We present our results of combining inertial and video features to recognize human activities on different types of scenarios where we achieve an F 1 -measure of up to 79.6%.

в статье исследуются особенности критического мышления, его статуса в современном социальном пространстве в целом и в системе образования, в частности. В работе выделяются два основных направления анализа критического мышления. Первое из них ориентировано на обсуждение историко-философских и историко-логических контекстов формирования идей критического мышления. Второе – на понимание критического мышления как определенной методологической установки, которая проявляется в различных сферах анализа. В качестве примеров использования критического мышления как методологической установки рассматриваются такие сферы деятельности человека, как музыка, образование, проблемы современной пандемии. the article explores the features of critical thinking, its status in the contemporary social space, particularly, the education system. To this end, two major lines of analysis of critical thinking are identified. The first one focusses on discussing the historical-philosophical and historical-logical contexts in which the ideas of critical thinking developed. The second one concentrates on understanding critical thinking as a methodological framework present in various areas of analysis. As examples of critical thinking employed as a methodological framework, human activities such as music, education, and the current struggle against the pandemic are considered.

Critical Questioning

This chapter describes the impact of ethnographic methods on the study of transformation. Ethnographic methods comprise a bundle of tools, the most important of which remains participant observation. In general, ethnographic methods aim at insights into processes of meaning making by actors in everyday life. They focus on the plurality of experiences within processes of change and ambivalences in specific contexts, as well as on historical depth. The openness of ethnographic research design allows for unexpected results and critical questioning of taken-for-granted theoretical concepts. The chapter starts with a short overview of the historical development of ethnographic methods in relation to shifting paradigms of transformation. Examples of ethnographic research of (post-)socialist transformations substantiate the potential (and pitfalls) of ethnographic methods. One important insight is that the great diversity of socialist as well as post-socialist transformations do not follow a modernization blueprint, demonstrating the potential of ethnography in generating innovative theoretical approaches.

In this paper a dynamic model for competitive routing in multi user communication network is presented. Dynamics has been introduced by considering the status of the communication network over a period of time, time dependence of link capacity and availability, and accordingly the cost function. We use game theoretical concepts to analyze this model. We assume that each user of the communication network can control the amount of flow to optimize his gain (or to minimize cost).
