Postoperatīvas neiropātijas pēc v.saphena magna vai saphena parva ekstirpācijas vai ablācijas
2019
Mūsdienās HVM ir plaši izplatīta un rada ne tikai medicīniskas,bet arī kosmētiskas problēmas,kā dēļ, sevišķi sievietes,vēršas pēc ķirurģiskas palīdzības.Šobrīd pieejamās mazinvazīvās ārstēšanas metodes,salīdzinot ar flebektomiju,tiek asociētas ar mazāk blakus parādībām un komplikācijām.Tomēr viena no iespējamajām un smagākajām komplikācijām-apakšējo ekstremitāšu nervu bojājuma radīta neiropātija,iespējama visu ārstēšanas metožu rezultātā,lai gan parasti tiek asociēta ar v.saphena magna vai v.saphena parva ekstirpāciju vai ablāciju.Mērķis:noskaidrot neiropātiju biežumu dažādu HVM ķirurģiskās ārstēšanas metožu gadījumā.Materiāli: Prospektīvs pētījums.Pacienti tika sadalīti grupās atkarībā no …
Capacity Analysis in Downlink WCDMA Systems Using Soft Handover Techniques With SIR-Based Power Control and Site Selection Diversity Transmission
2006
This work analyzes the downlink performance of a WCDMA system with site selection diversity transmission power control (SSDT) during soft handover mode. Signal to interference ratio (SIR) power control techniques are modeled and used in the simulations of this analysis. The study is focused on finding the optimum soft handover margin in terms of maximum system capacity under energy-per-bit to noise spectral density ratio (Eb/N0) quality requirements. The results of this analysis show an increase in user capacity of about 15 -20 % for optimum soft handover margins of 5 – 5.5 dB. Nevertheless, the resources required (number of scrambling codes) by base station increase faster than the number …
A Survey on Proxy Mobile IPv6 Handover
2016
[EN] As wireless technologies have been improving in recent years, a mobility management mechanism is required to provide seamless and ubiquitous mobility for end users who are roaming among points of attachment in wireless networks. Thus, Mobile IPv6 was developed by the Internet Engineering Task Force (IETF) to support the mobility service. However, Mobile IPv6 is unable to fulfill the requirements of real-time applications, such as video streaming service and voice over IP service, due to its high handover (HO) latency. To address this problem, Proxy Mobile IPv6 (PMIPv6) has been introduced by the IETF. In PMIPv6, which is a network-based approach, the serving network controls mobility m…
Nutritional screening of older home-dwelling Norwegians: a comparison between two instruments.
2012
Ulrika Söderhamn, Bjørg Dale, Kari Sundsli, Olle SöderhamnCentre for Caring Research-Southern Norway, Faculty of Health and Sport Sciences, University of Agder, Grimstad, NorwayBackground: It is important to obtain knowledge about the prevalence of nutritional risk and associated factors among older home-dwelling people in order to be able to meet nutritional challenges in this group in the future and to plan appropriate interventions. The aim of this survey was to investigate the prevalence of home-dwelling older people at nutritional risk and to identify associated factors using two different nutritional screening instruments as self-report instruments.Methods…
Lived experiences of self-care among older, home-dwelling individuals identified to be at risk of undernutrition
2012

Nutrition is a central aspect of se…
Psychometric testing of the Norwegian version of the Nutritional Form For the Elderly among older home-dwelling people
2012
Ulrika Söderhamn, Bjørg Dale, Kari Sundsli, Solveig T Tomstad, Olle SöderhamnCenter for Caring Research, Southern Norway, Faculty of Health and Sport Sciences, University of Agder, Grimstad, NorwayBackground: Nutritional screening instruments need to be evaluated in terms of reliability and validity and being able to demonstrate sensitivity and specificity for use in clinical practice and research. The aims of this study were to test the reliability and validity of the Norwegian version of the Nutritional Form For the Elderly (NUFFE-NO) in a sample of older home-dwelling people, and to use the short form of the Mini Nutritional Assessment (MNA-SF) as a standard.…
Psychometric properties of the Norwegian version of the General Health Questionnaire (GHQ-30) among older people living at home
2012
Bjørg Dale, Ulrika Söderhamn, Olle SöderhamnCentre for Caring Research – Southern Norway, Faculty of Health and Sport Sciences, University of Agder, Grimstad, NorwayIntroduction: The incidence and prevalence of mental problems among older people are difficult to map because the causes are often complex and the symptoms manifest in a range of ways. Therefore, there is a need for robust and useful instruments for screening mental problems in this group. One instrument used in Norway and around the world is the 30-item version of the General Health Questionnaire (GHQ-30). Nevertheless, studies testing reliability and validity of the Norwegian version are …

Joint User Association and Dynamic Beam Operation for High Latitude Muti-beam LEO Satellites
2021
In Low Earth Orbit (LEO) satellites, which run in polar orbit, the area of overlap among beams becomes wider as the latitude of satellites increases, which leads to intolerable interference and extra energy consumption. To minimize the onboard power with QoS requirements, we propose an energy optimization model with considering power allocation, user association and dynamic beam ON/OFF operation jointly. Moreover, the frequent beam ON/OFF operations lead to the large number of user handovers, so handover cost is also considered in the model. The original problem is decomposed into two levels due to the high coupling of variables and the successive convex approximation is employed. A low com…
Handover management in heterogenous mobile and wireless networks
2015
Since 1990, networking and mobile technologies have made a phenomenal unprecedented progress. This progress has been experienced on multiple fronts in parallel; especially on the application level and the user's needs one. This rapid evolution of the technology imposed a need for the existence of heterogeneous environments where the coverage is ensured throughout the different available networks. The challenge with such architecture would be to provide the user with the ability to navigate through the different available networks in a transparent and seamless fashion. However, the navigation among different types of networks is commonly referred to as vertical Handover. The IEEE 802.21 stan…
