Goalkeeper Analytics Using a Wearable Embedded System
Bogdan IANCU 5
The aim of this research is to identify the main metrics linked to soccer goalkeeping that can be computed by using a small embedded device. Based on the identified KPIs, a prototype is created by using an old Android phone in order to compute them based on the values of the three sensors related to positioning: accelerometer, gyroscope and magnetometer. In the final part of this paper, the obtained results are validated in a real case scenario by comparing the values of computed KPIs against some baseline values. The baseline values are extracted from the video recording of the trainings where the goalkeepers used our wearable embedded system. By constructing a cheap and small version of our prototype, we can help small soccer teams to understand and use data to better train their goalkeepers.

A scalable architecture for automated monitoring of microservices
Radu BONCEA, Alin ZAMFIROIU, Ioan BACIVAROV 13
In this paper we propose an architecture for monitoring microservices by logging key performance metrics at both system and application levels. By using advanced analytics algorithms we can then classify the events in microservice's behaviour and automate the decision processes, thus improving the overall reliability and security. We will be using Prometheus for storing short-live metrics, OpenTSDB for long term retention and RabbitMQ for passing structured messages between various IT components which orchestrate the collection of our microservices.

IT Agile Transformation
Cristian Gabriel OLTEANU 23
The paper presents a case study on knowledge management for IT Agile adaptation, based on organizational changes. It includes discussions about future knowledge management challenges and favorable circumstances within Agile transformation process in terms of its pre-requisites. As shown in the research results, the entire organization was impacted by adopting Agile as a project management approach. The conclusions point out some of the most important pre-requisites for Agile transformation, such as: training and workshops, implication of Agile experts, support and effectiveness, establishment of community practice and learning organizational culture. Nevertheless, the endless learning process as a part of the learning organizational culture, was the biggest Agile challenge within companies transformation, which is like a journey without a final destination, always having to adapt to changes.

The Way of Cryptocurrency
Mircea Constantin ȘCHEAU, Pop Ștefan ZAHARIE 32
Cryptocurrency market is estimated at several hundred billion dollars. The number of digital coins has exceeded the threshold of one thousand, each day appearing or disappearing some of them. Volatility, the difficulty in practical operation, high cost, associated risk and particular complexity make it quite difficult to choose one of the products without adequate counseling. Proponents of new technologies presents relevant arguments, while the appellants their call attention to the potential hazards/dangers to which expose themselves the investors. Reality offers us a spectrum that combines measures to limit the phenomenon development with the recognition and support from national and international organisms from which, however, is expected to adopt a joint position on the approach. Born at the end of the first decade of the second millennium, cryptocurrency has begun and continues to raise the interest of financial markets in general and specialized institutions in particular.
