Along with the increasing in demand of mobile computing, Push Notification (PN) is widely used in mobile phones and other devices. PN allows the developer to send messages to the end users even when the client application is not running at the moment. This solves the problem produced by non-supported multi-tasking feature as well as saving battery life. Microsoft Push Notification Service (MPNS) is one solution to use PNs in Windows Phones. The thesis gives the developers an idea of how to use PNs by introducing MPNS, comparing MPNS with other Push Notification Services, usage of different PN types analysis, and PN simulation system implementation.

Tämän tutkimuksen tutkimuskohteena oli case-yrityksen tuoteinnovaation kannattavuuden tarkastelu. Kiristyneen ilmastopolitiikan seurauksena tutkimuksen kohdeyritys on kehittänyt innovaation ja tutkimuksen päätavoite oli laatia kohdeyritykselle innovaation myyntityön tueksi Microsoft Excel-taulukkolaskentaohjelmalla investointilaskentatyökalu. Toisena tavoitteena oli selvittää innovaation, eli liikkuvien työkoneiden hybridisoinnin, kannattavuus investointilaskelmien avulla. Investointilaskelmien lisäksi tutkimuksessa perehdyttiin korkean teknologian markkinointiin ja yritysasiakkaiden käyttäytymiseen innovaatioiden omaksujina. Tutkimus on tyypiltään laadullinen tapaustutkimus. Investointilaskentatyökalu rakennettiin kohdeyrityksen tarpeiden mukaan ja investointien kannattavuutta mitattiin korottoman ja korollisen takaisinmaksuajan, sisäisen koron sekä nettonykyarvon avulla, minkä lisäksi nettonykyarvolle tehtiin herkkyysanalyysi. Kannattavuuslaskelmat tehtiin omaksujan näkökulmasta myyntityön tueksi kohdeyritykselle. Investointilaskelmat osoittivat että kohdeyrityksen tuottama innovaatio on kannattava sijoitus ja tutkimustuloksena syntynyt konstruktio osoittautui toimivaksi. Laskelmiin vaikutti eniten investoinnin hinta ja polttoaineen hinnan nousulla oli merkittävä vaikutus investoinnin kannattavuuteen.

The net radiation (Rn) represents the main source of energy for physical and chemical processes that occur in the surface-atmosphere interface, and it is used for air and soil heating, water transfer, in the form of vapor from the surface to the atmosphere, and for the metabolism of plants, especially photosynthesis. If there is no record of net radiation in certain areas, the use of information is important to help determine it. Among them we can highlight those provided by remote sensing. In this context, this work aims to estimate the net radiation, with the use of products of MODIS sensor, in the sub-basins of Entre Ribeiros creek and Preto River, located between the Brazilian states of Goiás and Minas Gerais. The SEBAL (Surface Energy Balance Algorithm for Land) was used to obtain the Rn in four different days in the period of July to October, 2007. The Rn results obtained were consistent with others cited in the literature and are important because the orbital information can help determine the Rn in areas where there are not automatic weather stations to record the net radiation.

This study aimed to apply mathematical models to the growth of Nile tilapia (Oreochromis niloticus) reared in net cages in the lower São Francisco basin and choose the model(s) that best represents the conditions of rearing for the region. Nonlinear models of Brody, Bertalanffy, Logistic, Gompertz, and Richards were tested. The models were adjusted to the series of weight for age according to the methods of Gauss, Newton, Gradiente and Marquardt. It was used the procedure "NLIN" of the System SAS® (2003) to obtain estimates of the parameters from the available data. The best adjustment of the data were performed by the Bertalanffy, Gompertz and Logistic models which are equivalent to explain the growth of the animals up to 270 days of rearing. From the commercial point of view, it is recommended that commercialization of tilapia from at least 600 g, which is estimated in the Bertalanffy, Gompertz and Logistic models for creating over 183, 181 and 184 days, and up to 1 Kg of mass , it is suggested the suspension of the rearing up to 244, 244 and 243 days, respectively.

Tässä työssä tutkitaan tietovaraston latausprosessin kehittämisen nopeuttamista Mic-rosoft SQL Server 2008 -ympäristössä. Työn teoriaosuudet on tarkoitettu tukemaan sekä työn tutkimus- että käytännönosia. Aiheeseen liittyviä tutkimuksia käytiin läpi parhaiden latausprosessin kehittämiseen kuluvaa aikaa vähentävien tapojen selvittä-miseksi. Nykytutkimus keskittyy valmistajasta riippumattomien mallien kehittämiseen ja valmistajakohtaisen latausprosessin luomiseen näiden mallien pohjalta. Yleinen konsensus parhaan mallin suhteen kuitenkin puuttuu. Aiheeseen liittyvien tutkimusten pohjalta esitetään arkkitehtuuri, joka saattaisi tule-vaisuudessa vähentää latausprosessin kehittämiseen kuluvaa aikaa huomattavasti. Tästä arkkitehtuurista luotiin yksinkertaistettu versio sekä siihen pohjautuva sovellus nopeuttamaan latausprosessin kehittämistä Microsoftin ETL-työkalulla.

In this paper, a Petri Net approach is introduced for modelling and simulation of control strategies in Intelligent Building. In this context, it is claimed that integration with other building systems can be achieved in a more systematic way considering a mechatronic approach (i.e. multidisciplinary concepts applied to the development of systems). The case study is the Ambulatory Building of Medical School Hospital of University of São Paulo. Particularly, the developed methodology is applied to the elevator system and to the HVAC (Heating, Ventilation and Air Conditioning) system. It is shown that using this approach, the control systems could be integrated, improving performance.

Tässä työssä selvitettiin Microsoft BizTalk Server -tuotteen sopivuutta moniasiakasjärjestelmänä toimivan sovellusintegraatioympäristön toteuttamiseen. Työssä ei otettu kantaa ympäristössä suoritettaviin integraatioihin, niihin liittyviin asiakkuuksiin tai integraatioympäristöön liittyviin järjestelmiin ja sovelluksiin. Selvityksessä ilmeni, että Microsoft BizTalk Server -tuotetta on mahdollista käyttää moniasiakasjärjestelmänä, sillä lisenssiehdot eivät rajoita tuotteen käyttömahdollisuuksia. Moniasiakasjärjestelmän haasteet liittyvät tietoturvaan ja sovellustietojen näkyvyyteen. Toisaalta haasteena on moniasiakasjärjestelmän kannattavuus liiketoiminnan näkökulmasta.

In a just-in-time, assemble-to-order production environments the scheduling of material requirements and production tasks - even though difficult - is of paramount importance. Different enterprise resource planning solutions with master scheduling functionality have been created to ease this problem and work as expected unless there is a problem in the material flow. This case-based candidate’s thesis introduces a tool for Microsoft Dynamics AX multisite environment, that can be used by site managers and production coordinators to get an overview of the current open sales order base and prioritize production in the event of material shortouts to avoid part-deliveries.

The present study analyzes Na+ and K+ disturbances caused by low pH in two catfish species from the Amazon River. Corydoras adolfoi inhabits ion-poor, black-stained, low pH (3.5-4.0) waters, while C. schwartzi is native to ion-rich waters at circumneutral pH. Fish were exposed to pH 3.5 Ca2+-free, and Ca2+-enriched (~500 µmol/l) water to determine the protective effects of calcium. Net Na+ and K+ fluxes were measured in the water collected from the fish experimental chambers. C. adolfoi was unable to control the Na+ efflux at low pH, exhibiting Na+ loss up to -594 ± 84 nmol g-1 h-1 during the first hour. After 3 and 6 h, net Na+ flux increased by 7- and 23-fold, respectively. In C. schwartzi, at pH 3.5, the initial high Na+ loss (-1,063 ± 73 nmol g-1 h-1) was gradually attenuated. A K+ loss occurred in both species, but remained relatively constant throughout exposure. High [Ca2+] affected ion losses in both species. C. adolfoi had 70% loss attenuation, indicating incapacity to control Na+ efflux. In C. schwartzi, elevated [Ca2+] completely prevented the Na+ losses caused by exposure to low pH. Rather different patterns were seen for K+ fluxes, with C. adolfoi showing no K+ disruption when exposed to low pH/high [Ca2+]. Thus, C. adolfoi loses Na+ during acid exposure, but has the ability to control K+ loss, while C. schwartzi controls diffusive Na+ loss but exhibits a slightly higher K+ loss. Ion balance was influenced by [Ca2+] at low pH in C. schwartzi but not in C. adolfoi.
