On Erlang B-formula and ERT method extension
2010
The key result of the paper is the theorem on traffic splitting and the ERT method extension for estimation of the throughput for schemes with traffic splitting. The excellent accuracy (relative error is less than 1%) is shown in numerical example. The paper also contains new Erlang-B formula algorithm for non-integer number of channels based on parabolic approximation.

The Internet as a Pedagogical Tool in the Writing Process: A Research-Based Approach
2017
This article examines how the Internet can be used to ease the process of writing by suggesting resources for the planning, writing and revising stages and how they can be used to carry out a writing task. One such resource is the Blackboard platform, which serves as a discussion tool and for teacher-to-student and student-to-student feedback. Based on sound L2 writing theories and ICTs, a pedagogical proposal for a writing task is proposed and explained that involves invention and organizing techniques; peer and teacher evaluation using the Blackboard platform; activities to practice argumentative skills, the five-paragraph essay and paragraph structure and evaluation sheets with criteria …
Energy-efficient routing control algorithm in large-scale WSN for water environment monitoring with application to Three Gorges Reservoir area
2013
Published version of an article in the journal: The Scientific World Journal. Also available from the publisher at: http://dx.doi.org/10.1155/2014/802915 Open Access The typical application backgrounds of large-scale WSN (wireless sensor networks) for the water environment monitoring in the Three Gorges Reservoir are large coverage area and wide distribution. To maximally prolong lifetime of large-scale WSN, a new energy-saving routing algorithm has been proposed, using the method of maximum energy-welfare optimization clustering. Firstly, temporary clusters are formed based on two main parameters, the remaining energy of nodes and the distance between a node and the base station. Secondly,…
Joint Dynamic Resource Allocation for Coupled Heterogeneous Wireless Networks Based on Hopfield Neural Networks
2008
This paper proposes an algorithm to solve the problem of Joint Dynamic Resource Allocation in heterogeneous wireless networks. The algorithm is based on Hopfield Neural Networks to achieve fast and suboptimal solutions. The generic formulation is particularized and evaluated in an HSDPA and 802.11e WLAN coupled networks. Some illustrative simulations results are presented to evaluate the performance of the new algorithm as compared with other strategies. The obtained results confirm the validity of the proposal.
Teollisen internetin hyödyntäminen toiminnanohjauksessa
2016
Teollinen internet on ollut informaatioteknologiatutkimuksen yksi ajankohtaisimmista aiheista. Yritysmaailmassa asiakkaat sekä toimittajat ovat todella kiinnostuneita teollisen internetin mahdollisuuksista. Teollista internetiä onkin pidetty mahdollisena seuraavana digitaalisena vallankumouksena. Palvelujen toiminnanohjauksessa ja yleisesti toiminnanohjauksessa on tapahtunut viimeisimpinä vuosina vain vähäisiä muutoksia, mutta nyt teollisen internetin odotetaan mullistavan jopa perinteiset toiminnanohjauksenjärjestelmät ja -prosessit. Yritykset niin teollisen internetin että toiminnanohjauksen alueilla ovat todella kiinnostuneita näiden kahden palasen yhdistämisestä ja sen tuomista mahdolli…
Capacity Estimation of ADSL links
2008
Most tools designed to estimate the capacity of an Internet path require access on both end hosts of the path, which makes them difficult to deploy and use. In this paper we present a single-sided technique for measuring the capacity without the active cooperation of the destination host, focusing particularly on ADSL links. Compared to current methods used on broadband hosts, our approach generates two orders of magnitude less traffic and is much less intrusive. Our tool, DSLprobe, exploits the typical characteristics of ADSL, namely its bandwidth asymmetry and the relatively low absolute bandwidth, in order to measure both downlink and uplink capacities and to mitigate the impact of cross…
Sensitivity and mode spectrum of a frequency-output silicon pressure sensor
1988
The vibrational mode spectrum of a silicon vibrating pressure sensor is investigated. Particular attention is given to the analysis of the vibration shapes, quality factors and relative sensitivity of the resonance frequencies as a function of pressure. It is shown that a pressure sensitivity of a few parts per million at one atmosphere can be achieved. Some comments are also made regarding an improved design of the device.

Manipulating Self-Avatar Body Dimensions in Virtual Worlds to Complement an Internet-Delivered Intervention to Increase Physical Activity in Overweig…
2020
Virtual reality has been found to be a useful tool for positively influencing relevant psychological variables in order to increase physical activity (PA), especially in the overweight population. This study investigates the use of avatars and their physical variations to extend the effectiveness of existing interventions to promote PA. The main objective is to analyze the influence of the avatars&rsquo
