Alone at home

2008

Recently there has been much public discussion about children spending long afternoons alone at home. It has been claimed that spending a lot of time alone makes children vulnerable to many kinds of risk behaviour, such as smoking, use of alcohol and drugs, depression and poor school performance. Concerns have also been voiced about children’s unsupervised television watching, playing of computer games and surfing on the Internet. Yet, do we actually know how long the times are that children do spend alone at home and what do they do during that time? The purpose of this paper is to study how much time youngsters in Finland spend alone at home, who are the youngsters who are alone and what …

Project Risk Register Analysis Based on the Theoretical Analysis of Project Management Notion of Risk

2016

Abstract The aim of the current research is to examine publicly available project risk registers to find correlations between the project management theory, especially project risk management, and practical results of real project risk management – the risk registers publicly available on the Internet. In the research, the author has analysed the compliance between the theories of the project risk management described in the “Aid Delivery Methods. Volume I. Project Cycle Management Guidelines” and “Caltrans Project Risk Management Handbook, Threats and Opportunities, Second Edition, Revision 0” and the project risk registers. In the previous studies, the author concluded that after analysin…

<title>Revenue-maximization-based adaptive WFQ</title>

2002

In the future Internet, di erent applications such as Voice over IP (VoIP) and Video-on-Demand (VoD) arise with di erent Quality of Service (QoS) parameters including e.g. guaranteed bandwidth, delay jitter, and latency. Different kinds of service classes (e.g. gold, silver, bronze) arise. The customers of di erent classes pay di erent prices to the service provider, who must share resources in a plausible way. In a router, packets are queued using a multi-queue system, where each queue corresponds to one service class. In this paper, an adaptive Weighted Fair Queue based algorithm for traAEc allocation is presented and studied. The weights in gradient type WFQ algorithm are adapted using r…

PCP-DV: An End-to end Admission Control Mechanism for IP Telephony

2001

In this paper we describe a novel endpoint admission control mechanism for IP telephony:the PCP-DV which is characterized by two fundamental features. First, it does not rely on any additional procedure in internal network routers other than the capability to apply different service priority to probing and data packets. Second, the triggering mechanism for the connection admission decision is based on the analysis of the delay variation statistics over the probing flow. Numerical results for an IP telephony traffic scenario prove that 99th delay percentiles not greater than few ms per router are guaranteed even in overload conditions.

A Migration Path for the Internet: From Best-Effort to a QoS Capable Infrastructure by Means of Localized Admission Control

2000

Looking back at many proposals appeared on the scene in these years, a fundamental lesson to be learned is that their success or failure is strictly tied to their backward compatibility with existing infrastructures. In this paper, we consider the problem of providing explicit admission control decisions for QoS aware services. We rely the decision to admit a new flow upon the successful and timely delivery, through the Internet, of probe packets independently generated by the end points. Our solution, called GRIP (Gauge&Gate Realistic Internet Protocol), is fully distributed and scalable, as admission control decisions are taken at the edge network nodes, and no coordination between router…

A dynamic multi-sink routing protocol for static and mobile self-organizing wireless networks: A routing protocol for Internet of Things

2021

Abstract With the rapid advent of using various devices like smart phones, vehicles etc, the connection of these devices with the help of Internet connectivity has emerged to IoT paradigm. The interconnection of smart objects under the various real world constraints like communication technologies, network scalability, node mobility, energy consumption etc, is a big challenge and requires designing new robust, adaptive, dynamic, and configurable routing protocols. With the arrival of the 5G and the future Internet, the latency time will be extremely reduced, this motivated us to propose a new protocol that entrust internet to transport a large part of control and data traffic of the network…

An optimized path-selection using airtime metric in OLSR networks: Implementation and testing

2008

Wireless mesh networks used for broadband access may be equipped with multiple Internet gateways. Using airtime metric as the main criterion for path selection is an effective method for achieving load-balancing in such a multi-homed mesh network. In this paper, we describe how the radio-aware path selection using airtime as a metric can be implemented in order to achieve this functionality, based on a modified version of an open source OLSR implementation. The paper presents both the principle of this method, its implementation and the empirical results which focus on testing the airtime metric functionality based on a deployed small-scale test network.

Abstract This article explores trolling as a form of literary activity. It presents a number of specific types of trolling on the Russian-language Internet in connection with digital literature and the literary practices of various groups of Internet users. Techniques for writing provocative “troll-texts” were created and developed within subcultural groups in the 1990s. Later, from being a subversive practice known only to a few insiders, it became a mass technique described in meta-texts that identified rules for trolling and shared facts about its culture with all interested users. In the 2010s, the now popularised techniques of trolling came to be seen as effective strategies to deploy …

The occupation of Runet? : The tightening state regulation of the Russian-language section of the internet

2019

In this chapter, we scrutinise the Russian state’s regulation for political purposes of the Russian-language section of the internet or ‘Runet’, as it is often dubbed in Russia. We will focus on those regulative actions which came into force during and after the protest wave in Russia in 2011–2013. Internet and social media played an important role in the mobilisation of these protests that challenged the legitimacy of the ruling elite. We argue that the protests marked a watershed moment in the Russian government’s information policy, which had previously mainly functioned through the control of the federal Russian TV channels. After the protests, the Kremlin mounted a campaign to regulate…

Automatische Anästhesieprotokollsysteme

1997

The introduction of electronic anaesthesia documentation systems was attempted as early as in 1979, although their efficient application has become reality only in the past few years. The advantages of the electronic protocol are apparent: Continuous high quality documentation, comparability of data due to the availability of a data bank, reduction in the workload of the anaesthetist and availability of additional data. Disadvantages of the electronic protocol have also been discussed in the literature. By going through the process of entering data on the course of the anaesthetic procedure on the protocol sheet, the information is mentally absorbed and evaluated by the anaesthetist. This i…
