Efficiency Analysis Of Resource Request Patterns In Classification Of Web Robots And Humans
2018
The paper deals with the problem of classification of Web traffic generated by robots and humans on e-commerce websites. Due to the still growing proliferation and specialization of bots, a large body of research into characterization and recognition of their traffic has been conducted so far. In particular, some approaches to classify bot and human sessions on websites have been proposed in the literature. In this paper we verify and discuss the efficiency of such recently proposed approach, which uses differences in resource request patterns of bots and humans. We reconstructed Web sessions from actual HTTP log data for three different e-commerce sites, varying in the traffic intensity an…
ES Pamattiesību Hartas izmantošana Eiropas Savienības Tiesas judikatūrā un Hartas piemērojamības robežas
2015
Šī pētījuma mērķi ir noskaidrot Pamattiesību Hartas pielietojumu EST judikatūrā un noteikt Hartas piemērojamības robežas. Harta ir ES pamattiesību aizsardzības instruments, kurš galvenokārt attiecas uz Savienības iestādēm un struktūrām. Tomēr, piepildoties zināmiem priekšnosacījumiem, Harta var garantēt vis efektīvāko indivīda aizsardzības mehānismu arī dalībvalstu līmenī. Galvenais apstāklis, kas dalībvalstu līmenī liedz piemērot Hartu visās situācijās ir Hartas 51.pantā noteiktās piemērojamības robežas. Pētījuma rezultātā būs iespējams noteikt, kuras pamattiesības ir visbiežāk aizskartas ES līmenī un, kas ir šo pamattiesību šķietamais aizskārējs – Savienības institūcijas vai dalībvalsts. …
Plūsmas asimptotisks atrisinājums šķidra metāla paraugā stipros mainīgos un pastāvīgos magnētiskos laukos
2018
Darbā ir veikts aprēķins cilindrā šķidra metāla plūsmai, kuru dzen kombinēts mainīgs un pastāvīgs magnētiskais lauks. Šāda lauka forma tiek izmantota nanodaļiņu izkliedēšanai šķidros metālos. Gadījumā ar stipru pastāvīgu magnētisko lauku, cilindra izliekumu laukam paralēlajā robežslāni var neņemt vērā. Kad mainīgā lauka radītais skinslānis ir daudz lielāks par robežslāni, stacionārā plūsma ir atkarīga tikai no viena parametra, kas nosaka nelineāro inerciālo locekļu svaru. Vienādojumi ir atrisināti analītiski mazām galvenā parametra vērtībām un ar divām skaitliskām spektrālajām metodēm pie lielām parametra vērtībām gan ar pielipšanas robežnosacījumu, gan ar brīvu virsmu vertikālajai sānu rob…
Communities of Communication: Making Sense of the “Social” in Social Media
2012
As social media usage permeates people's lives, an increasing portion of their daily behavior leaves digital traces to be used by researchers. Social scientists can hope to gain new insight into the previously hidden but digitally recorded aspects of our digital social lives. Beyond aggregate and individual-level studies of user behavior, the digital traces also enable scientific examination of the structure of social interaction through networks. At the same time, the large scale and networked nature of social media data pose a new set of challenges to be overcome through the development of sound methodologies. We take stock of current methodological promises and challenges in social media…
Learning Laparoscopic Radical Hysterectomy: Are We Facing an Emerging Situation?
2023
Despite wide screening campaigns and early detection, cervical cancer remains the fourth most common cancer among women. Radical hysterectomy, whether by open, laparoscopic or by robotic-assisted techniques, is the mainstay treatment. However, for adequate surgical results and good oncological prognosis, a gynecological surgeon should be trained to perform those procedures. The learning curve of radical hysterectomy, especially by laparoscopy, is influenced by several factors. The LACC trial, the decrease in cervical cancer incidence and radical hysterectomy procedures have widely reduced the learning curve for surgeons. This article mainly discusses the learning curve of laparoscopic radic…
Bayesian correlated models for assessing the prevalence of viruses in organic and non-organic agroecosystems
2017
Cultivation of horticultural species under organic management has increased in importance in recent years. However, the sustainability of this new production method needs to be supported by scientific research, especially in the field of virology. We studied the prevalence of three important virus diseases in agroecosystems with regard to its management system: organic versus non-organic, with and without greenhouse. Prevalence was assessed by means of a Bayesian correlated binary model which connects the risk of infection of each virus within the same plot and was defined in terms of a logit generalized linear mixed model (GLMM). Model robustness was checked through a sensitivity analysis …
Data from: Phylogenomics of Lophotrochozoa with consideration of systematic error
2021
Phylogenomic studies have improved understanding of deep metazoan phylogeny and show promise for resolving incongruences among analyses based on limited numbers of loci. One region of the animal tree that has been especially difficult to resolve, even with phylogenomic approaches, is relationships within Lophotrochozoa (the animal clade that includes molluscs, annelids, and flatworms among others). Lack of resolution in phylogenomic analyses could be due to insufficient phylogenetic signal, limitations in taxon and/or gene sampling, or systematic error. Here, we investigated why lophotrochozoan phylogeny has been such a difficult question to answer by identifying and reducing sources of sys…

Empirical Likelihood-Based ANOVA for Trimmed Means
2016
In this paper, we introduce an alternative to Yuen’s test for the comparison of several population trimmed means. This nonparametric ANOVA type test is based on the empirical likelihood (EL) approach and extends the results for one population trimmed mean from Qin and Tsao (2002). The results of our simulation study indicate that for skewed distributions, with and without variance heterogeneity, Yuen’s test performs better than the new EL ANOVA test for trimmed means with respect to control over the probability of a type I error. This finding is in contrast with our simulation results for the comparison of means, where the EL ANOVA test for means performs better than Welch’s heteroscedastic…
