Atgriezto preču apstrādes procedūras pilnveidošana uzņēmumā X
2016
Uzņēmums X Latvijā ir ieviesis līdz šim nebijušu E-komercijas veidu- jaunu un mazlietotu preču noma interneta vidē. Pakalpojums pats par sevi šķiet līdzīgs līzingam vai kredītam, taču pakalpojuma galvenā atšķirība ir tā, ka ir iespēja jebkurā brīdī atgriezt preci, kad tā nav vairs vajadzīga, līdz ar to ir iespējams lauzt līgumu un pārtraukt līgumsaistības. Diplomdarba mērķis ir izpētīt uzņēmuma pašreizējo atgriezto preču apstrādes procesu, identificēt tā darbībā iesaistīto procedūru trūkumus un uzlabošanas iespējas. Veikt atgriezto preču apstrādes procesa pilnveidošanu, izmantojot uzdevumu pārvaldības sistēmu, uzlabot, kā arī izstrādāt jaunas procedūras, kas uzlabotu un atvieglotu uzņēmuma …
Photomagnetic effect in a cyanide-bridged mixed-valence {FeII2FeIII2} molecular square
2012
The self-assembly of [Fe(III)(Tp)(CN)(3)](-) and [Fe(II)(bik)(2)(S)(2)](2+) affords the cyanide-bridged mixed valence {Fe(III)(2)Fe(II)(2)}(2+) molecular square, which exhibits a photomagnetic effect under laser light irradiation at low temperature and also shows thermal spin-state conversion near ambient temperature.
Kristības elementi apgaismības laikmeta daiļliteratūrā
2018
Apgaismības laikmets ir periods, kas ilga no 17. gadsimta beigām līdz 18. gadsimta beigām un ievērojami ietekmēja tā laika kultūru, reliģiju un politiku. Tas bija laiks, kad radās jaunas filozofiskas idejas, kas veicināja racionalitātes un zinātnes attīstību; un tajā pašā laikā virzīja prom no paļaušanās uz Dieva Vārdu. Taču kristietības ietekme šajā laika periodā bija tik pat liela kā agrāk, jo tās mācība bija svarīga daudzām ticīgo paaudzēm. Tāpēc ir interesanti apskatīt kā tik dažādas parādības pastāvēja vienlaikus. Bakalaura darba mērķis ir izpētīt kā daži no kristietības elementiem, kas tika atspoguļoti daiļliteratūrā, mainījās Apgaismības periodā; un kā tie tika aprakstīti tā laika ro…
Innovation in lighting for enhancing the appreciation and preservation of archaeological heritage
2014
Abstract The cultural content of ancient sites highlights the importance of light, which is an essential tool for the correct appreciation of the historical value and memory of cultural heritage. This should be a new way to highlight significance of fragments in compliance of the surrounding, which has not the same characteristics, to signal a visual path, creating itineraries that involve the context. Light plays a very important role in creating emotion, suggestion, evocation and supporting the visitor experience. Innovative technological solutions should be designed taking into account the kind of landscape and morphological characteristics of the site. This paper presents the study of a…
Ecological Indicator Values for Europe (EIVE) 1.0
2023
Aims: To develop a consistent ecological indicator value system for Europe for five of the main plant niche dimensions: soil moisture (M), soil nitrogen (N), soil reaction (R), light (L) and temperature (T). Study area: Europe (and closely adjacent regions). Methods: We identified 31 indicator value systems for vascular plants in Europe that contained assessments on at least one of the five aforementioned niche dimensions. We rescaled the indicator values of each dimension to a continuous scale, in which 0 represents the minimum and 10 the maximum value present in Europe. Taxon names were harmonised to the Euro+Med Plantbase. For each of the five dimensions, we calculated European values fo…
Ellenberg-type indicator values for European vascular plant species
2022
This is a dataset of Ellenberg-type indicator values for European vascular plant species described in this article: Tichý L., Axmanová I., Dengler J., Guarino R., Jansen F., Midolo G., Nobis M.P., Van Meerbeek K., Aćić S., Attorre F., Bergmeier E., Biurrun I., Bonari G., Bruelheide H., Campos J.A., Čarni A., Chiarucci A., Ćuk M., Ćušterevska M., Didukh Y., Dítě D., Dítě Z., Dziuba T., Fanelli G., Fernández-Pascual E., Garbolino E., Gavilán R.G., Gégout J.-C., Graf U., Güler B., Hájek M., Hennekens S.M., Jandt U., Jašková A., Jiménez-Alfaro B., Julve P., Kambach S., Karger D.N., Karrer G., Kavgacı A., Knollová I., Kuzemko A., Küzmič F., Landucci F., Lengyel A., Lenoir J., Marcenò C., Moeslun…
Verkkojen piirtäminen Silverlightilla
2012
Silverlight-teknologialla voidaan tehdä mm. näyttäviä web- ja mobiilisovelluksia. Tutkielmassa selvitetään Silverlightin soveltuvuutta verkkojen piirto-ohjelman tekemiseen. Tutkielmassa ohjelmoitiin piirto-ohjelma, joka havainnollistaa ratsun polun etsintää shakkilaudalla. Ohjelman kehitysprosessin aikana huomattiin, että Silverlight soveltuu tutkielman mittaluokan verkoille. Silverlight-sovellus saattaa kuitenkin hidastua, jos sovellukseen tuodaan reaaliaikaisia tapahtumia vaativia tai pelimäisiä elementtejä. Tällöin voi olla järkevää vaihtaa XNA-kehitykseen Windows-ympäristössä.
The optimisation of the angle of inclination of a solar collector to maximise the incident solar radiation
1999
Abstract Irradiation data, recorded on vertical surfaces facing north, south, east and west and on a horizontal surface every ten minutes during daylight hours from January–December 1992 in Valencia, Spain, have been compared with estimated solar irradiation from inclined-surface models. Results show that Hays model most accurately reproduces the variation in irradiation on all vertical surfaces. Hays model has been used to find the hourly variation in the optimum tilt angle for a South-facing solar collector in Valencia, Spain, and also to calculate the yearly average of this angle. This method has been compared with the results provided by another model that uses average monthly values of…
Light Curves of Radio Supernovae
2007
We present the results from the on-going radio monitoring of recent type II supernovae (SNe), including SNe 2004et, 2004dj, 2002hh, 2001em, and 2001gd. Using the Very Large Array to monitor these supernovae, we present their radio light-curves. From these data we are able to discuss parameterizations and modeling and make predictions of the nature of the progenitors based on previous research. Derived mass loss rates assume wind-established circumstellar medium, shock velocity ~10,000 km/s, wind velocity ~10 km/s, and CSM Temperature ~10,000 K.
General remarks on the role of the vestibular system in weightlessness
1987
Different methods are described to experimentally achieve weightlessness. Since the function of the otolith system depends on the presence of contact forces opposing gravity, it is disabled in weightlessness and may send misleading positional information to the brain. Without the contributions of the otolith system it is difficult in space to distinguish self-motion from object motion. Furthermore, the disintegration of information from the neck position receptors from those of the otolith system can lead to additional illusory positional sensations. Since the function of the semicircular canal system in previous space flights was found to be essentially undisturbed, the vestibular experime…
