Computer networks stability independence of the queuing delays
2015
Communication in intelligent computer networks is an indispensible attribute of the dataflow quality in Web traffic. We propose a model that investigates intelligent computer networks stability while specifying its limits. Packet queuing delay affects the performance of the network, and especially its stability. If the network is presented as a dynamic system in block diagram form, we compute a transfer function and determine the quasi-polynomial system. The characteristic polynomial distribution of zeros of complex variable quasi-plane determines the boundaries of the network stability. The approach relies on estimation of the network system's transfer functions and its quasi-polynomial. C…
Web Tool for Path Analysis in Wireless Sensor Networks to Improve Their Performance
2018
Wireless Sensor Networks (WSNs) are based on tiny autonomous devices, usually named motes or nodes, and are used in many monitoring applications, such as environment, habitat, precision horticulture, etc. These motes are power-limited and most energy is wasted through the communication process when exchanging data packets. Because these motes are quite simple, with low power transmission and simple antennas, these networks usually run multihop routing protocols in order to forward packets between one mote to the sink, or the collector node, using the other motes as relaying motes. Basically, these routing protocols try to find out new routes within these wireless network, optimizing differe…
Development of digital health messages for rural populations in Tanzania: Multi- And interdisciplinary approach
2021
Background Health workers have traditionally delivered health promotion and education to rural communities in the Global South in paper leaflet formats or orally. With the rise of digital technologies, health promotion and education can be provided in innovative and more effective formats, which are believed to have a higher impact on disease prevention and treatment. Objective The aim of this tutorial is to illustrate how a multi- and interdisciplinary approach can be applied in the design process of digital health messages for use in the Global South. Methods The multi- and interdisciplinary team of the Non-discriminating access for Digital Inclusion (DigI) project digitalized and custom…
Valodu centru mājaslapu analīze
2018
Šajā darbā uzmanība tiek veltīta galvenokārt Humanitāro zinātņu fakultātes Lietišķās valodniecības centra (LVC) apakšvietnes satura analīzei. Darba mērķis ir noteikt LVC mājaslapas semantiskos kodolus un pārbaudīt vietnes atslēgvārdu un atslēgu vārdkopu saderību Google meklētājprogrammā. Analīze tika veikta ar moderno Google rīku palīdzību un manuāli atpazīstot pašreizējos atslēgvārdus un atslēgu vārdkopas tīmekļa vietnes lapās. Šis pētījums uzsver semantiskā kodola sagatavošanas nozīmi pirms mājaslapas izstrādāšanas, kā arī to, kā ik pa laikam var pārbaudīt atslēgvārdu un atslēgu vārdkopu saderību (Google atpazīšanu). Empīriskais pētījums tika īstenots izmantojot kvalitatīvo un kvantitatīv…
Usage and Dose Response of a Mobile Acceptance and Commitment Therapy App: Secondary Analysis of the Intervention Arm of a Randomized Controlled Trial
2016
Background: Mobile phone apps offer a promising medium to deliver psychological interventions. A mobile app based on Acceptance and Commitment Therapy (ACT) was developed and studied in a randomized controlled trial (RCT). Objective: To study usage metrics of a mobile ACT intervention and dose-response relationship between usage and improvement in psychological flexibility. Methods: An RCT was conducted to investigate the effectiveness of different lifestyle interventions for overweight people with psychological stress. This paper presents a secondary analysis of the group that received an 8-week mobile ACT intervention. Most of the analyzed 74 participants were female (n=64, 86%). Their me…
Relaatio- ja epärelaatiotietokantojen suorituskykyvertailu : MySQL ja MongoDB
2016
Tutkielmassa esitellään relaatio- ja epärelaatiotietokantoja sekä paneudutaan niiden ominaisuuksiin. Nykyään erilaisia tietokantahallintajärjestelmiä on paljon. Ongelmaksi tulee se, että mikä tietokantahallintajärjestelmä on järkevin valinta uudelle ohjelmistoprojektille. Valinnan tärkeyttä korostaa vielä se, että kehitettävä ohjelma tulee olemaan sidottu kyseiseen tietokantaan koko projektin aikajänteen ja sen vaihtaminen projektin edetessä tulee päivä päivältä kalliimmaksi. Alkuvaiheessa tehtävät valinnat voivat mennä hyvin helposti pieleen, koska tarpeellista toimialakohtaista osaamista ja kokonaisuuden hahmotusta ei ole välttämättä pystytty sisäistämään täydellisesti. Tutkielman tarkoit…
