Uzņēmējdarbības procesa izveide SharePoint sadarbības sistēmā
2019
Kvalifikācijas darbs apraksta komercprojektu reģistrācijas sistēmu. Šī sistēma ir paredzēta uzņēmumiem, kas strādā ar Sharepoint vidi. Tas ļauj uzņēmuma darbiniekiem, kuriem ir piekļuve serverim, izveidot un aizpildīt reģistrācijas veidlapu, kas satur informāciju par savu nākotnes projektu vai to rezultātus viegli pieejamā PDF formātā, kā arī iespēju uzņēmuma “galveniem” dot atļauju tās īstenošanai. Sistēmā ir trīs galvenas lietotāju grupas. Katrai lietotāju grupai ir paredzētas noteiktas iespējas izmantot informāciju, kas ir ievadīta PDF veidlapā. Izstrādātās sistēmas mērķis ir automatizēt jaunu projektu reģistrāciju ķīmijas rūpniecībā, kas paātrinās darba procesu un atvieglos komunikāciju…
Response spectrum analysis of frame structures: reliability-based comparison between complete quadratic combination and damping-adjusted combination
2019
In the framework of seismic design of structures, response spectrum analysis (RSA) is the most commonly used approach in practice. The most popular combination rule is the complete quadratic combination (CQC) which is also prescribed by the most of seismic design codes and is based on the assumptions that the seismic acceleration is a white noise process and the peak factor ratios associated to the total and modal responses are unitary. Recently, the damping adjusted combination (DAC) rule has been developed for base-isolated structures to overcome the aforementioned simplified assumptions. Although it has been proved that the simplifications about peak factors lead to noticeable errors in …
Infopath tehnoloģijas iziešana no aprites - iespējamie aizvietotāji un to analīze
2016
Šajā darbā tiek runāts par veidlapu izmantošanu SharePoint vidē. Tika pētīta InfoPath Forms risinājuma funkcionalitāte un integrācija ar SharePoint vidi. Darba mērķis bija izpētīt alternatīvus risinājumus, kuri var aizstāt InfoPath Forms, par kuru tika izziņots, ka tas izies no aprites. Tika apskatīti produkti, kas ir piedāvāti InfoPath tematiskajās vietnēs. Tika analizētas risinājumu iespējas, vājās vietas un guvumi, salīdzinājumā ar InfoPath. Darbā tika aprakstīts katra rīka, parastas veidlapas izveides process un ir apkopoti secinājumi. Darbā tika izveidots viens no populārākiem InfoPath veidlapas darbplūsmas scenārijiem un tika pārbaudīts, kā katrs no piedāvātiem aizvietotājrīkiem pārva…

Préparation et spéciation d’oxo-clusters de métaux du bloc p
2022
The main subject of this thesis is the use of Pair Distribution Function (PDF) analysis for solution phase speciation during metal-cluster growth. The PDF method allows the extraction of structural information from a sample in the form of an atom-atom distance distribution via Fourier transform of synchrotron X-ray scattering data. The growth mechanisms of two solution-based systems are analysed in this thesis. Precursor materials are synthesized through a mechanochemical method that was developed and shown to be able to access a wide range of related systems.Mechanochemical routes of synthesizing bismuth Active Pharmaceutical Ingredients (APIs) were investigated and optimised. Samples were…
Nuclear structure functions at a future electron-ion collider
2017
The quantitative knowledge of heavy nuclei's partonic structure is currently limited to rather large values of momentum fraction $x$---robust experimental constraints below $x\ensuremath{\sim}{10}^{\ensuremath{-}2}$ at low resolution scale ${Q}^{2}$ are particularly scarce. This is in sharp contrast to the free proton's structure which has been probed in Deep Inelastic Scattering (DIS) measurements down to $x\ensuremath{\sim}{10}^{\ensuremath{-}5}$ at perturbative resolution scales. The construction of an electron-ion collider (EIC) with a possibility to operate with a wide variety of nuclei, will allow one to explore the low-$x$ region in much greater detail. In the present paper we simula…
Probing the small- x nuclear gluon distributions with isolated photons at forward rapidities in p+Pb collisions at the LHC
2014
Inclusive direct photon production in p+Pb collisions at the LHC is studied within the NLO perturbative QCD. Our aim is to quantify the dominant $x$ regions probed at different rapidities and to identify the best conditions for testing the nuclear gluon parton distribution functions (nPDFs) at small $x$. A comparison to the inclusive pion production reveals that from these two processes the photons carry more sensitivity to the small-$x$ partons and that this sensitivity can be further increased by imposing an isolation cut for the photon events. The details of the isolation criteria, however, seem to make only a small difference to the studied $x$ sensitivity and have practically no effect…
Measurement of azimuthal hadron asymmetries in semi-inclusive deep inelastic scattering off unpolarised nucleons
2014
Spin-averaged asymmetries in the azimuthal distributions of positive and negative hadrons produced in deep inelastic scattering were measured using the CERN SPS muon beam at $160$ GeV/c and a $^6$LiD target. The amplitudes of the three azimuthal modulations $\cos\phi_h$, $\cos2\phi_h$ and $\sin\phi_h$ were obtained binning the data separately in each of the relevant kinematic variables $x$, $z$ or $p_T^{\,h}$ and binning in a three-dimensional grid of these three variables. The amplitudes of the $\cos \phi_h$ and $\cos 2\phi_h$ modulations show strong kinematic dependencies both for positive and negative hadrons.
Pion–nucleus Drell–Yan data as a novel constraint for nuclear PDFs
2017
We have studied the prospects of using the Drell-Yan dilepton process in pion-nucleus collisions as a novel input in the global analysis of nuclear parton distribution functions (nPDFs). In a NLO QCD framework, we find the measured nuclear cross-section ratios from the NA3, NA10 and E615 experiments to be largely insensitive to the pion parton distributions and also compatible with the EPS09 and nCTEQ15 nPDFs. These data sets can thus be, and in EPPS16 have been, included in global nPDF analyses without introducing significant new theoretical uncertainties or tension with the other data. In particular, we explore the constraining power of these data sets on the possible flavour asymmetry in…
Applicability of pion-nucleus Drell-Yan data in global analysis of nuclear parton distribution functions
2017
Despite the success of modern nuclear parton distribution functions (nPDFs) in describing nuclear hard-process data, they still suffer from large uncertainties. One of the poorly constrained features is the possible asymmetry in nuclear modifications of valence $u$ and $d$ quarks. We study the possibility of using pion-nucleus Drell-Yan dilepton data as a new constraint in the global analysis of nPDFs. We find that the nuclear cross-section ratios from the NA3, NA10 and E615 experiments can be used without imposing significant new theoretical uncertainties and, in particular, that these datasets may have some constraining power on the $u$/$d$ -asymmetry in nuclei.
