Design time, run time, and artificial intelligence techniques for mobility of user interface
2011
Abstract Advancement in technology provides opportunities to user as well as challenges for application development organization. User interfaces which were design for specific device tend to be developed for various devices. Users are busy people, when they move among different context would like to move application with them. The current trend of users demanding mobile graphic user interface to support their daily life and work has led to a new generation of techniques. Design time technique provides better usability as compare to run time technique. On the other hand artificial intelligence technique like agent provides better flexibility and usability as compare to others. In this paper…
Theoretical Analysis of the M12Ag32(SR)404– and X@M12Ag32(SR)304– Nanoclusters (M = Au, Ag; X = H, Mn)
2014
We analyze the electronic structure and optical properties of the recently reported, structurally known M12Ag32(SR)304– clusters (M = Au, Ag) by using density functional theory and time-dependent density functional perturbation theory. Effects of the chemical changes in the metal core, charge of the cluster, and nature of the thiolate ligand on the electronic structure and optical absorption are reported. In addition, doping the metal core with a magnetic transition metal atom (Mn) or hydrogen (protons) is discussed. Although all these clusters can be considered as 18-electron superatoms with a shell configuration 1S2 1P6 1D10, we find that the optical spectrum is sensitive to the charge st…
Role of Vibrational Dynamics in Electronic Relaxation of Cr(acac)3
2015
Ultrafast energy relaxation of Cr(acac)3 dissolved in tetrachloroethylene (TCE) is studied by time-resolved infrared (TRIR) spectroscopy by using electronic and vibrational excitation. After electronic excitation at 400 or 345 nm, the ground state recovers in two time scales: 15 ps (major pathway) and 800 ps (minor pathway), corresponding to fast electronic transition to the ground state and intermediate trapping on the long-lived (2)E state followed by intersystem crossing (ISC) to the ground state. The quantum yield for the fast recovery of the ground state depends on the excitation wavelength, being higher for 345 nm. Vibrational cooling (VC) occurs on the electronic excited states with …
Total Structure and Electronic Structure Analysis of Doped Thiolated Silver [MAg24(SR)18]2– (M = Pd, Pt) Clusters
2015
With the incorporation of Pd or Pt atoms, thiolated Ag-rich 25-metal-atom nanoclusters were successfully prepared and structurally characterized for the first time. With a composition of [PdAg24(SR)18](2-) or [PtAg24(SR)18](2-), the obtained 25-metal-atom nanoclusters have a metal framework structure similar to that of widely investigated Au25(SR)18. In both clusters, a M@Ag12 (M = Pd, Pt) core is capped by six distorted dimeric -RS-Ag-SR-Ag-SR- units. However, the silver-thiolate overlayer gives rise to a geometric chirality at variance to Au25(SR)18. The effect of doping on the electronic structure was studied through measured optical absorption spectra and ab initio analysis. This work d…
Exercising exclusions: Space, visibility, and monitoring of the exercising fat female body
2019
The author’s aim is to inspect the position of the fat (female) body in the field of exercise. Specifically, the author is interested in fat women’s experiences of their treatment while exercising in public, and argues that, in particular, public spaces for exercise, such as gyms and swimming pools, are currently discursively and concretely constructed as “exclusive” spaces for the normative bodied. Bodies that are deemed non-normative, such as fat bodies, are often made either invisible or intolerable in the discourse of physical activity and exercise. Consequently, public spaces for exercise such as gyms or swimming pools are seen as out of bounds for non-normative bodies and this is refl…
Nāves eifēmizācija japāņu valodā
2019
Eifēmismi ir izteikumi, kurus izmanto netīkamu, nepiedienīgu vārdu aizvietošanai. Viens no semantiskajiem laukiem, kas tiek īpaši pakļauts eifēmizācijai, ir nāve un mirstība, kas izraisa bailes un nepatiku cilvēkos no visdažādākajām vidēm. Bieži cilvēku lietotie eifēmismi ir skaidrojami ar konceptuālo metaforu - garīgo tēlu, kas ietekmē mūsu izzināšanas spējas. Bakalaura darba “Nāves eifēmizācija japāņu valodā” mērķis ir identificēt visaptverošas konceptuālās metaforas, kuras atspoguļo eifēmismu lietošanu saistībā ar nāvi un mirstību japāņu valodā. Darbs sastāv no četrām daļām. Pirmajā daļā tiek definēts termins ‘eifēmisms’ un tiek sniegti vairāki termina skaidrojumi, kā arī tiek izklāstīti…
Taste perception: from molecule to eating behaviour
2020
The sense of taste has a role in human nutrition, it help to orient our food choices and avoid the ingestion of toxi compounds. Advances in molecular biology, cell biology an, biochemistry were used to identify and characterize the main taste receptors. The identification of these receptors allow a better understanding of the physiological processes tha govern taste perception. The presence of genetic polymorphisr in these receptors explains interindividual differences in tast perception.
Teachers’ situational physiological stress and affect
2023
Since teaching is a demanding and stressful profession, the study of teachers’ physiological stress in the classroom setting is an emerging field. In cross-sectional studies self-reported stress and affect are related, but less is known about the intraindividual relations between situational physiological stress and corresponding positive and negative affect. The aim of our study was to investigate the associations between situational physiological stress (six salivary cortisol samples per day) and self-reported situational affect (Positive and Negative Affect Schedule four times a day) among 61 Finnish primary school teachers over two workdays. We present a novel multilevel structural equa…
Virtuālās realitātes tehnoloģijas kā apziņas metafora
2020
Maģistra darbā “Virtuālās realitātes tehnoloģijas kā apziņas metafora” tiek aplūkots šīs metaforas pielietojums mūsdienu apziņas filozofijas kontekstā. Darba mērķis ir pierādīt, ka, neskatoties uz virtuālās realitātes metaforas noderīgumu konkrētos kontekstos, tai ir ievērojami ierobežojumi un problēmas, kas traucē raksturot fenomenālo apziņu. Darba pirmajā daļā tiek aplūkotas senākas tehnoloģiju metaforas (prāts kā automāts, tvaika dzinējs un dators). Otrajā daļā tiek apskatīts virtuālās realitātes metaforas pielietojums mūsdienu apziņas filozofijas tekstos, lai noskaidrotu metaforas pielietošanas pamatojumu. Trešajā daļā tiek veikta šīs metaforas analīze, lai noskaidrotu tās ierobežojumus…
Metaforizētu terminu tulkošanas problēmas medicīnas terminoloģijā – franču-latviešu valodās
2016
Bakalaura darbs ir veltīts metaforu analīzei medicīnas terminoloģijā, kā arī to tulkošanas īpatnībām no franču uz latviešu valodu. Darba mērķis ir izpētīt metaforizētus medicīnas terminus abās minētajās valodās, lai realizētu komparatīvo, kvalitatīvo un kvantitatīvo analīzi par visbiežāk medicīnas terminoloģijā sastopamajiem metaforu tipiem, lai apskatītu, kāda ir metaforas loma terminoloģijā, kā arī, lai noskaidrotu, kādas tulkošanas metodes izmantot to tulkošanas procesā. Lai izstrādātu korpusu, tika izmantotas vairākas tulkotas publikācijas medicīnas nozarē no franču uz latviešu valodu, medicīnisko terminu tiešsaistes vārdnīca Dictionnaire de l’Academie Française, kā arī citas medicīnas …
