Vliv srážkových vod na provozování kanalizační soustavy a čistírny odpadních vodLysák, Martin January 2017 (has links)
This thesis deals with current issues in the discharge of waste water from the urbanized area. The main aim is to evaluate the impact of rainwater on the existing unified sewerage system and the wastewater treatment plant in Brno. The theoretical part includes a brief assessment of the current state of the sewerage system of the city of Brno and the basic concepts as well as their use in everyday practice. The practical part focuses on monitoring the quantity and quality of rainwater in the sewage system at the wastewater treatment plant in Brno. These indicators have a direct impact on the safe operation of the sewerage system and wastewater treatment plants within the urban drainage. From this perspective, the work is focused on the evaluation of substance rainwater pollution discharged from busy traffic roads, both in the case of using of a single sewerage system for wastewater treatment and using a separate sewerage system that water to the recipient. To evaluate the function of the municipal sewerage system during extreme precipitation when the sewerage system is overloaded and wastewater overflows over the strain into the recipient. The contribution of the construction of one of the newly implemented retention basins was assessed. At the end of the sewerage system, ie.at the wastewater treatment plant, there were monitored changes in material composition, as well as the quantity and temperature of the influent wastewater during precipitation events, which affect the individual cleaning processes. In the conclusion, there is made an overall evaluation of the impact of precipitation water on drainage system of the city of Brno and its wastewater treatment plant. At the same time, there are evaluated newly designed concepts of drainage with respect to the already implemented measures for minimizing the impact of operational activities of sewerage system on the environment, especially the measures that aim to reduce the bag load of recipient.

VOD-tjänster : Faktorer för en ökad diffusion och användaracceptansBrodén, Fredrik, Karamehmedovic, Alen January 2013 (has links)
I den här uppsatsen har faktorer för en ökad användaracceptans och diffusion av Video on demand(VOD)-tjänster identifierats med hjälp av en litteraturgenomgång av tidigare studier i acceptans och diffusion. Litteraturgenomgången ligger till grund för en lista av faktorer som gör en konsument mer villig att anamma en VOD-tjänst. Faktorerna har sedan utvärderas genom en kvantitativ undersökning med hjälp av en webbenkät. Resultatet blev i stor grad det som förväntat där det framgår att utbud och kostnad är de viktigaste faktorerna för en hög acceptans, men även andra faktorer kan spela in som användarvänlighet, kvalitet och sociala faktorer. / This paper has identified factors for increased user acceptance and diffusion of Video on Demand(VOD) services through a literature review of previous studies. The literature review was used to make a list of factors that make a consumer more willing to use a VOD service. The factors are then evaluated through a quantitative study using an online questionnaire. The result was to a large degree what was expected, which shows that content and cost are the main factors for a high acceptance, but other factors may play in as well such as ease-of-use, quality, and social factors.

Utvecklingen av ett föråldrat medielandskapBastin, Andreas, Wibom, Henrik January 2015 (has links)
Syfte: Vi vill ta reda på hur teknikutvecklingen relaterad till VoD påverkar beteendet hos unga vuxna och hur detta beteende förändrar tv-tittandet i denna målgrupp. Teori: Denna studie använder huvudsakligen två teorier för att undersöka problemet. Den första teori som tas upp är Diffusion of innovation, Rogers (2003) som diskuterar innovationers spridning och påverkan i samhället. För att vidare undersöka beteendet hos unga vuxna används Jakob Bjurs avhandling Transforming Audiences (2009) som undersöker individualiseringens mönster inom tv-tittande. Metod: En kvalitativ empirisk fallstudie baserad på intervjuer av fokusgrupper samt personintervju. Detta stöds av en kvantitativ undersökning i syfte att skapa en triangulering för att minimera risken för en felaktig tolkning av resultatet. Resultat: Unga vuxna vill inte längre anpassa sig till tv-tablåer. Generationen blir allt mer individualiserad och vill därför välja helt på egen hand var och när de skall titta på exempelvis ett tv-program. Medieföretagen är medvetna om detta skifte från linjär-tv till VoD och således finns ett fokus på att utveckla ett mer individ-anpassat tittande. Trots individualiseringen och de förbättrade VoD-tjänsterna vill många se bland annat nyheter, större sportevenemang samt melodifestivalen via linjär-tv. Slutsats: Den största anledningen till att många gör denna övergång från linjär-tv till VoD är att de söker en flexibilitet som linjär-tv inte kan erbjuda. Flexibiliteten har gjorts möjlig genom den teknikutveckling som skett inom datorer, smarttelefoner och surfplattor. Det som lockar många VoD-användare till att fortfarande titta på linjär-tv är de sändningar som är viktiga att se i realtid. Tack vare dessa kommer förmodligen tv-tittandet finnas kvar en tid framöver, dock ser vi sjunkande tittarsiffror i de yngre generationerna vilket gör framtiden för linjär-tv oviss.

Čištění komunálních odpadních vod v domovních kořenových čistírnách - hygienické aspekty a možnosti využití v podmínkách ČR / Wastewater Treatment Using House Sewage Treatment Plants {--} Hygienic Aspects and Usage in the Czech RepublicFIŠEROVÁ, Alena January 2009 (has links)
Constructed wetlands (CWs) originate from natural wetlands and are used for waste water treatment as an alternative to conventional treatment. This thesis was aimed at providing a literary summary of the types of house sewage water treatment plants and constructed wetlands used in the CR and abroad, of their hygienic aspects, functionality, treatment efficiency, expensiveness and the possibilities of their use in the conditions of the CR and their advantages and disadvantages. It also deals with a proposal of a suitable type of house CW for the conditions of the CR and a list of the necessary steps in construction of a house CW. Quite similar systems are being used for house sewage treatment in the Czech Republic and abroad {--} mostly septic tanks, ground mounds, constructed wetlands, active treatment plants and biodiscs. Alternative water treatment methods are generally not suitable for buildings having (now or in the future) the possibility of connection to municipal sewerage systems. They are on the other hand suitable for buildings not connected to sewerage systems or for seasonal objects, remote places and holiday houses with seasonal waste water production. A system with horizontal subsurface flow is mostly used as a CW in the Czech Republic. This CW type ensures sufficient removal of organic contamination and insoluble substances, but the efficiency of nitrogen and phosphorus removal is relatively low. However it is fully sufficient in the instance of low PE numbers, as the loading rate is usually low and the concentration of contaminants in the output water meets the prescribed limits. Foreign researches show that hybrid systems combining horizontal flow with vertical flow and with recirculation are more suitable for improving efficiency of nitrogen removal. Systems with vertical flow and intermittent waste water dosage showing particularly good results in ammoniac removal are also suitable for nitrogen removal. Special materials with higher iron, aluminium or calcium content are most suitable as filling of a constructed wetland or as additional filters or for improvement of phosphorus removal from waste water as they are able to reach efficiency of up to 90 %. In my thesis I came to a conclusion that a CW with horizontal subsurface flow is the most suitable type of house constructed wetland treatment for the conditions in the CR, mainly because it is the most frequently used and thus best proven CW type with sufficient efficiency of treatment for the substances required by standards.

Právní úprava územní ochrany vod z hlediska množství / Legal regulation of territorial protection of water in terms of quantityDvořák, Petr January 2017 (has links)
The thesis deals with the legal regulation of territorial protection of water in terms of quantity, which is contained in the Water Act. I am only focusing on the Protected Areas of Natural Water Accumulation and Surface Water Accumulation Protected Areas as they have significant potential to reduce the effects of drought. Both areas are viewed through common problem, which is the point of view of the amount of water. The legal regulation of the territorial protection of waters in terms of quantity is discussed in connection with other laws. The aim of this work is to answer the question whether the legal regulation of territorial protection of waters in terms of quantity in the Water Act is sufficient to enable the Czech Republic to adapt adequately to the ongoing climate change, that ultimately causes the loss of water. The first part of the thesis deals with sources of legal regulation of territorial protection of water in terms of quantity, further includes the systematics of the Water Act and the Strategy on Adaptation to Climate Change in the Czech Republic (Adaptation Strategy of the Czech Republic). The second part analyses the Protected Areas of Natural Water Accumulation, prohibitions therein contained prohibitions, exemption from prohibitions and damage compensation. The third part deals...
