Resource Allocation and Computation Offloading for Wireless Powered Mobile Edge Computing
2022
In this paper, we investigate a resource allocation and computation offloading problem in a heterogeneous mobile edge computing (MEC) system. In the considered system, a wireless power transfer (WPT) base station (BS) with an MEC sever is able to deliver wireless energy to the mobile devices (MDs), and the MDs can utilize the harvested energy for local computing or task offloading to the WPT BS or a Macro BS (MBS) with a stronger computing server. In particular, we consider that the WPT BS can utilize full- or half-duplex wireless energy transmission mode to empower the MDs. The aim of this work focuses on optimizing the offloading decision, full/half-duplex energy harvesting mode and energ…
Knowledge organization for modelling workflows in Taverna environment
2014
Today Workflow Management Systems (WFMS), like Taverna and Kepler, have a very important place in the everyday work of the scientist. These tools support the access to computational resources and act as interface for building complex data processing chains. The next step is to support decisions of the researcher on autonomously developing workflow parts guided by requirements of the scientist while she/he is working on the high-level goal of the experiment. To this aim, it is necessary an ontology to store the knowledge related to the experiments and tools used, and to make this knowledge available not only to the scientist, but also to a suitable artificial intelligent system. In this pape…
New floristic data of alien vascular plants from Sicily

Analysis of the Potential of an Increase in Yeast Output Resulting from the Application of Additional Process Wastewater in the Evaporator Station
2019
This paper reports the results of an analysis of process wastewater streams in the context of an increase in yeast production. This research is based on the analysis of data from the biggest yeast factory in Europe. The research presented in this paper involves the analysis of the influence of direction of additional wastewater into the evaporator station on yeast production. In the process wastewater, nitrogen is mainly present in organic forms. The analysis reported in this paper involves the concentration of total nitrogen in wastewater streams, as it is the main parameter applied to determine the amount of wastewater that can be applied in agricultural fields. Directing additional waste…
The importance of phytoplankton production for carbon budgets in a semiarid floodplain wetland
2011
Phytoplankton production (PP) in wetlands is not measured as often as that of macrophytes. A three year-study during a period of sustained high flooding was undertaken in a central Spanish floodplain wetland (Las Tablas de Daimiel National Park) to determine net PP, its spatial heterogeneity and controlling factors, and compare it with primary production in macrophyte communities. This enabled us to estimate carbon budgets for each community. All PP variables showed high spatial and temporal variability among sites, resulting in low coherence even when flooding connected all sites. Net PP corresponded to 25- 36% of submerged plant production and 3-10% of helophyte production. Net PP was con…
Rubefacientu (mentola un niacīna) izraisīto mikrocirkulācijas reakciju novērtējums ādas dažādos dziļumos
2017
Ādai ir lokāla neiro-imuno-endokrīnā sistēma, kas lielā mērā atspoguļo organisma norises, kalpojot par sava veida „veselības indikatoru”. Īpaši pievilcīga un relatīvi pieejama ir ādas mikrocirkulācijas funkciju novērtēšana, ko var neinvazīvi veikt ar optiskām metodēm. Parasti praksē šādu reakciju novērtēšanai tiek lietoti standartizēti provokācijas testi, kā, piemēram, lokālas sildīšanas tests, vai acetilholīna jontoforēze. Taču bieži vien ādas sarežģītā mikrocirkulācija un liela regulācijas mehānismu daudzveidība apgrūtina rezultātu viennozīmīgu interpretāciju. Šajā kontekstā daudzsološa šķiet bispektrālā attēlveides fotopletizmogrāfija - optiska metode ar kuras palīdzību, izmantojot atšķi…
Floras izplatības izmaiņas Kurzemes piejūras ciemos pēdējo 20 gadu laikā: Bērzciema piemērs
2015
Bakalaura darba „Floras izplatības izmaiņas Kurzemes piejūras ciemos pēdējo 20 gadu laikā: Bērzciema piemērs” mērķis ir apzināt floras sastāva un telpiskās izplatības izmaiņas Bērzciema apkārtnē pēdējo 20 gadu laikā un noskaidrot to ietekmējošos faktorus. Katrai sugai ir noteiktas prasības pēc vides apstākļiem, tādēļ floras izmaiņas ir netiešs informācijas avots par pārmaiņām apkārtējā vidē. Lai noskaidrotu, kā mainījusies Bērzciema apkārtnes flora pēdējo 20 gadu laikā un kas bijuši pārmaiņu virzītājspēki, analizēti divu floras uzskaišu rezultāti. Pirmā no tām notikusi 20.gs. 80.-90.gados, bet otrā – 2012.-2013.gadā. Apkopojot rezultātus, secināts, ka Bērzciema apkārtnē augu sugu skaits nav…

ANOTĀCIJA Priede A. 2009. Invazīvie neofīti Latvijas florā: izplatība un dinamika. Promocijas darbs. Latvijas Universitāte, Rīga, 127 lpp. Pētījuma mērķis bija noskaidrot invazīvo neofītu izplatības dinamikas un vides faktoru kopsakarības Latvijā reģionālā kontekstā. Darba ietvaros analizēta neofītu izplatība un dinamika Latvijas mērogā un divās modeļteritorijās. Aprakstītas un klasificētas izplatītākās lakstaugu neofītu sabiedrības, kā arī, balstoties uz fitosocioloģiskajiem aprakstiem, novērtēta invazīvo neofītu ietekme uz augu sabiedrību sugu sastāvu. Sagatavotas dažāda mēroga izplatības kartes, un analizēta neofītu floras un izplatības dinamika un to ietekmējošie faktori. Izplatības kop…
Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…
2014
The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
Flagship species of the Pieniny NP. protected ex situ at PAS BGCBDC seed bank at WARSAW-POWSIN
2014
Pieniny Mts. are important biodiversity hotspot in Central Europe. According to Pieniny National Park Long Term Conservation Plan 2000-2020 small, isolated populations of some of Pieniny NP flagship species can become extinct till 2020. That is why their ex situ preservation at seed bank is justified and reasonable as supplement of active and passive in situ conservation measures carried out by National Park staff. PAS Botanical Garden – Center for Biological Diversity Conservation at Warsaw-Powsin has a long tradition of cooperation with Pieniny National Park (S Poland). This article focuses on the actions undertaken during EU funded conservation project: “Ex situ conservation of native, t…
