Virtual Reality Arcades : A Study on Usage Habits with Emphasis on Digital Gaming
2019
Virtual reality (VR) and VR gaming have seen substantial advancement during the recent years both in terms of technological development and the number of users. A notable rise has also occurred in the number of VR arcades. Despite the growing academic interest towards VR and VR gaming, there is still a dearth of understanding on the usage aspects of VR gaming and VR arcades. To address this gap, this study explored the habits of using VR arcades with emphasis on digital gaming. Specific focus was set on investigating differences between gender, age, and physical activity background. The study was exploratory in nature and based on a quantitative analysis of data collected from 126 responden…
Virtuālo asistentu izmantošanas iespējas Latvijas uzņēmumu digitālā mārketinga stratēģijā.
2020
Konkurences apstākļos uzņēmumiem jādomā kā efektīvi veidot digitālā mārketinga stratēģiju, kas atbilst digitālā patērētāja prasībām. Virtuālais asistents ir datorprogramma, kas var būt veidota ar mākslīgo intelektu un sniedz organizācijām iespēju veidot jaunus saskarsmes punktus ar auditoriju, noturēt uzmanību un veicināt pārdošanu. Darba mērķis ir, pamatojoties uz teorētiskām atziņām par digitālo mārketingu un virtuālajiem asistentiem, un autores veikto pētījumu, izpētīt, novērtēt un analizēt virtuālo asistentu izmantošanas iespējas Latvijas uzņēmumu digitālā mārketinga stratēģijā, lai izstrādātu secinājumus un sniegtu priekšlikumus par iespējām izmantot virtuālos asistentus Latvijas uzņēm…
Virtuālo asistentu izmantošanas iespējas valsts pārvaldē.
2019
Virtuālie asistenti šobrīd ir trends, ko cenšas ieviest un izmantot dažādu industriju pārstāvji, tāpēc arī valsts pārvaldē nepieciešams ieviest virtuālos asistentus, lai uzlabotu darba rezultātus vai atslogotu darbiniekus augstākas pievienotās vērtības uzdevumu veikšanai. Pētījuma mērķis ir izpētīt virtuālo asistentu izmantošanas iespējas valsts pārvaldē, ieguvumus no to ieviešanas un izmantošanas, kā arī izstrādāt priekšlikumus virtuālo asistentu izmantošanai. Pētījuma rezultāti parāda, ka Latvijas valsts pārvalde plāno izveidot vienoto virtuālo asistentu platformu, bet ņemot vērā, ka lietotājiem nav virtuālā asistenta izmantošanas pieredzes, jāveic visas nepieciešamās darbības, lai nodroš…
Worm-like artifacts in exfoliative cytology.
2006
The presence of worms in cytological smears is occasionally reported, although various other structures exist that may be confused with such parasites. We present eight worm-like artifacts observed in routine Papanicolaou smears. Recognition of these structures is important to avoid overvaluation or confusion with true worms. Diagn.

Female genital schistosomiasis--a differential diagnosis to sexually transmitted disease: genital itch and vaginal discharge as indicators of genital…
2008
OBJECTIVE To examine the association between schistosomiasis and reproductive tract symptoms. METHOD A cross-sectional study was conducted in a Schistosoma haematobium-endemic area of rural Zimbabwe. A total of 483 permanently resident adult women of Mupfure Ward aged 20-49 were interviewed and examined clinically, each providing three consecutive urine samples. Logistic regression analysis was used to control for sexually transmitted diseases (STDs). RESULTS Women with genital sandy patches had significantly more genital itch (P = 0.009) and perceived their discharge as abnormal (P = 0.003). Eighty percent of the women who had genital itch, yellow discharge, and childhood or current waterb…
Full configuration interaction calculation of the low lying valence and Rydberg states of BeH
2007
The all-electron full configuration interaction (FCI) vertical excitation energies for some low lying valence and Rydberg excited states of BeH are presented in this article. A basis set of valence atomic natural orbitals has been augmented with a series of Rydberg orbitals that have been generated as centered onto the Be atom. The resulting basis set can be described as 4s2p1d/2s1p (Be/H) + 4s4p3d. It allows to calculate Rydberg states up to n= {3,4,5} of the s, p, and d series of Rydberg states. The FCI vertical ionization potential for the same basis set and geometry amounts to 8.298 eV. Other properties such as FCI electric dipole and quadrupole moments and FCI transition dipole and qua…
Multiconfigurational second-order perturbation calculation of the electronic absorption spectrum of trisilane, Si3H8
2002
The low-lying singlet excited states of trisilane have been computed using the complete active space self-consistent field (CASSCF) method, second-order perturbation theory (CASPT2), and the extended multistate CASPT2 (MS-CASPT2) approach, and a generally contracted basis set of atomic natural orbitals (ANOs) including Rydberg functions. The ground state structure was obtained from an ab initio optimization at the second-order M⊘ller-Plesset perturbation theory (MP2) level using Dunning's correlation-consistent triple-zeta basis set (cc-pVTZ) and agrees well with experiment. The calculation of the electronic transitions included the lower valence excited states and two Rydberg series conver…
A theoretical study of the electronic spectrum of bithiophene
1995
The electronic spectrum of bithiophene in the energy range up to 6.0 eV has been studied using multiconfigurational second order perturbation theory (CASPT2) and a basis set of ANO type, with split valence quality and including polarization functions on all heavy atoms. Calculations were performed at a planar (trans) and twisted geometry. The calculated ordering of the excited singlet states is 1Bu, 1Bu, 1Ag, 1Ag, and 1Bu with 0–0 transition energies: 3.88, 4.15, 4.40, 4.71, and 5.53 eV, respectively. The first Rydberg transition (3s) has been found at 5.27 eV. The results have been used in aiding the interpretation of the experimental spectra, and in cases where a direct comparison is poss…
On the dissociation energy of Cu2 and CuH using a differential correlation approach
1990
The energy contributions involved in the “dissociation-consistent configuration interaction” (DCCI) scheme proposed by Goddard and co-workers plus the dispersion effects associated with the valence MOs adjacent to the bond (DISP) are evaluated for the Cu2 and CuH systems, following the “configuration interaction by perturbation with multiconfigurational zeroth-order wavefunction selected by iterative process” (CIPSI) algorithm. Using a relativistic pseudopotential to represent the neon core of copper, and a flexible basis set for the valence shell, the results obtained with the CIPSI/DCCI (+ DISP) approach shows a good agreement with previous theoretical results employing basis sets of simi…
Rydberg, valence and mixed states in the vertical spectrum of HF
2009
Abstract Size-consistent self-consistent multireference singles and doubles configuration interaction (SC)2–MR–SDCI, and linear response coupled cluster of singles and doubles including triples LR–CCSDR(3) methods, with a basis set of ANO’s augmented with a single series of molecular Rydberg functions, have been applied to the calculation of vertical excitation energies of HF in the 10–16 eV region. Special care has been put in the description of the valence, Rydberg and mixed states. Some advantage has been taken from the different physical contents of the methods to discuss some assignments. The (4,5) f Rydberg states of HF are predicted at 15.2 and 15.5 eV.
