Research Perspectives: Reconsidering the Role of Research Method Guidelines for Interpretive, Mixed Methods, and Design Science Research
2021
Information systems (IS) scholars have proposed guidelines for interpretive, mixed methods, and design science research in IS. Because many of these guidelines have also been suggested for evaluating what good or rigorous research is, they may be used as a checklist in the review process. In this paper, we raise the question: To what extent do research guidelines for interpretive, mixed methods, and design science research offer evidence that they can be used to evaluate the quality of research. We argue that scholars can use these guidelines to evaluate what good research is if there is compelling evidence that they lead to certain good research outcomes. We use three well-known sets of gu…
An Optoelectronic System for Measuring the Range of Motion in Healthy Volunteers: A Cross-Sectional Study.
2019
Background and Objectives: Within the clinical evaluation of multiple pathologies of the lower limb, the measurement of range of motion (ROM) of its joints is fundamental. To this end, there are various tools, from the goniometer as a reference to more recent devices such as inclinometry-based applications, photo capture applications, or motion capture systems. This study aimed to assess the validity, intra-rater, and inter-rater reliability of the VeloFlex system (VS), which is a new camera-based tool designed for tracking joint trajectories and measuring joint ROM. Materials and Methods: Thirty-five healthy volunteers (16 females
Virtualizācijas risinājumi bezservera skaitļošanai ARM arhitektūrā
2020
Bezservera skaitļošana ir mākoņskaitļošanas modelis, kura mērķis ir abstrahēt sistēmu IT operāciju aspektus, ļaujot koncentrēties uz biznesa loģikas izstrādi. Tai raksturīgas slodzes, kuru apstrādē tradicionālo virtualizācijas risinājumu efektivitāte ir ierobežota. Nolūkā to uzlabot pēdējos gados parādās jauni, pielāgoti risinājumi. Autors, pamatojoties uz bezservera īpatnībām, izvirza 4 prasības, kuras ļauj novērtēt virtualizācijas risinājumu piemērotību bezservera skaitļošanai. Balstoties uz tām, darbā tiek kvalitatīvi analizēti kopumā seši virtualizācijas risinājumu tipi. Četriem no tiem, izmantojot Raspberry Pi 4B ierīci, veikta arī kvantitatīva analīze mērījumu formā. Darba problemātik…
Unity daudzlietotāju spēle ar neautoritatīvu servera risinājumu
2015
Daudzlietotāju spēles ir ļoti populāras mūsdienās, un viena no pieejam šādu spēļu tīkla strukturēšanā ir neautoritatīva servera risinājums. Neautoritatīva servera risinājumiem nav viena noteikta servera, kurš kontrolē visu spēles loģiku – spēles loģika tiek kontrolēta uz pašu spēlētāju ierīcēm, un katrs spēlētājs pats kontrolē darbības un to rezultātus. Darba mērķis ir izveidot stabilu un drošu daudzlietotāju spēli ar neautoritatīva servera risināju, izmantojot Unity spēļu dzini. Darbā ietvaros tika izstrādāta daudzlietotāju spēle ar neautoritatīva servera risinājumu. Darbā tiek apskatītas un risinātas ar spēles izstrādi saistītas problēmas un jautājumi - tīkla arhitektūras, komunikācijas p…
Real Time Localization Systems for autonomous navigation: Modelling, Analysis and Control
2021
Questo lavoro di tesi riguarda la derivazione di osservatori ibridi dello stato, analisi e controllo, di sistemi di localizzazione e navigazione in tempo reale (RTLS). In particolare, il framework dei sistemi ibridi è stato utilizzato per tener conto delle dinamiche continue e discrete coinvolte nel processo di stima e della natura sporadica e tempo randomica delle misure provenienti da vari sensori di distanza e/o inerziali. Analisi di convergenza sono state effettuate per dimostrare la stabilità delle soluzioni proposte e la capacità di filtraggio dei rumori presenti nelle misure. Il presente lavoro è corredato dai risultati delle prove sperimentali di laboratorio a conferma della validit…
Pasta servera “Zimbra” ieviešana mazā birojā
2016
Kvalifikācijas darba “Pasta servera Zimbra ieviešana mazā birojā” mērķis ir aizvietot birojā esošo pasta serveri un tā vietā ieviest pasta serveri Zimbra. Lai šo mērķi īstenotu, darba gaitā tika izpētīta Zimbras dokumentācija, tika veikta servera un tīkla sagatavošana Zimbras uzstādīšanai, tika uzstādīts un konfigurēts pasta serveris Zimbra, tika veikta lietotāju migrācija no esošā pasta servera uz pasta serveri Zimbra, kā arī tika izveidoti risinājumi Zimbras rezerves kopiju veidošanai un sistēmas atjaunošanai.
Active disturbance rejection control of linear induction motor
2017
This paper proposes the theoretical framework and the experimental application of the active disturbance rejection control to linear induction motors. Such a nonlinear control (ADRC) technique can be viewed as a particular kind of input-output linearization control, where the nonlinear transformation of the state is not computed by means of the model, but it is estimated online. Such an approach permits to cope with unmodelling dynamics, as well as uncertainty in the knowledge of the model parameters and exogenous disturbances. The effectiveness of the proposed ADRC control law has been verified both by numerical simulations and experimentally on a suitably developed test setup. Moreover, t…

Stiffness Estimation and Adaptive Control for Soft Robots
2022
Nonostante la sorprendente crescita nello sviluppo dei robot ispirati alla natura, tra cui i cosiddetti soft robot, il potenziale di questi sistemi, che hanno intrinseche capacità di adattamento, non è ancora stato sfruttato a pieno. La ricerca ha principalmente considerato il controllo in retroazione della posizione dei giunti del robot, lasciando la gestione della cedevolezza di questi ultimi ancora in anello aperto. Peraltro, le attuali limitazioni nel processo di produzione degli attuatori a cedevolezza variabile e l'inevitabile variabilità nel tempo degli elementi elastici costitutivi, i quali sono soggetti ad usura e deformazione plastica, rendono il problema della determinazione prec…
Is it possible to understand a book missing a quarter of the letters? Unveiling the belowground species richness of grasslands
2022
Abstract Knowledge of species richness patterns in plant communities is biased toward its hidden belowground part and is derived only from the part visible aboveground. Studies on the relationship of the above- to belowground parts of plant communities suffer from the lack of a consistent and uniform approach to assess their taxonomic composition, particularly in species-rich ecosystems. This study described the proportion between above- and belowground parts of vegetation in three grassland types along with the environmental factors that affect them, using eDNA metabarcoding and an observer survey. The internal transcribed spacer 2 (ITS2) region was used to analyze the total plant richness…
