We provide an analysis of the main sources of data used to estimate fertility schedules in developing countries, giving special attention to Brazil. In addition to the brief history of various data sources, we present several indirect demographic methods, commonly used to estimate fertility and assess the quality of data. From the methods used, the Synthetic Relational Gompertz model gives the most...
Nowadays, many emerging technologies, such as Augmented and Virtual reality, require extremely high-rate data transmissions. This imposes an increasing demand on the network throughput, which currently surpasses the capabilities of commercially available wireless communication systems. To address this constraint, some companies are considering the implementation of high-throughput wired technologies,...
As next-generation mobile networks are rapidly taking shape driven by the target standardization requirements and initial trial implementations, a range of accompanying technologies prepare to support them with more reliable wireless access and improved service provisioning. Among these are more advanced spectrum sharing options enabled by the emerging Licensed Shared Access (LSA) regulatory framework,...
Nowdays, wearables are very important part of Internet of Things (IoT) concept. They share a lot of parameters with embedded devices and add some new requirements. Most of those requirements are created by their unique usage - these devices are in user proximity, mostly directly on a human body. This brings also a lot of complications for researchers and engineers. They must consider i.e. safety terms...
The Internet of Things (IoT) represents a vision of a future communication between users, systems, and daily objects performing sensing and actuating capabilities with the goal to bring unprecedented convenience and economical benefits. Today, a wide variety of developed solutions for IoT can be seen through the all industry fields. Each of the developed systems is based on the proprietary SW implementation...
Today, one of the most engaging challenges for mobile operators is the question how to manage the data traffic in mobile networks which is increasing exponentially; mainly due to the growing popularity of applications for mobile devices. Mobile data offloading represents the idea of cost-efficient technology to release the overloaded parts of RAN in cellular networks. This emerging solution introduces...
A dramatic change in fertility,family formation and living arrangements tookplace in the Czech Republic over the 1990s. Theestablishment of democracy, profound socialtransformation and transition to the marketeconomy affected the values and demographicbehaviour of the young Czech generation. Thispaper examines whether these demographic shiftscan be interpreted within the framework of thesecond demographic...
