Utvärdering och åtgärdsförslag av energianvändning i kontorsbyggnad

AbstractEmbla 5 is an office building which has done a large improvement. The clients of this building has made an order of WSP and the student Anders Kempe to calculate the use of energy for the building, and after that result proposing further measures which can decrease the energy use of Embla 5.The ground for this report is when calculation of the present energy use of the building is stated. To make that information of a number of parameters such as envelope, the heating system and ventilation has been located and set in to the simulation program IDA ICE which calculate the energy use.To improve the energy use further this project has been concentrated to change the system of ventilation. Today the ventilation system is of the kind CAV (constant air volume) and the air flow is dimensioned for after recommendations from BBR and Arbetsmiljöverket in the office spaces. Consider that Embla 5  is an office building where the people only staying for 8-10 hours/day so was the ide to see how much energy saving if the air flow is reduced the time people not being in the building.

1-D Modellering av Piezoelektrisk Injektor

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

Utvärdering av lösningar för hårddiskkryptering

Information stored on unprotected computers that gets lost or stolen, and falls intothe wrong hands, can easily be accessed by moving the hard disk to a controlledcomputer, or by booting the computer from a removable medium, in order to getaround the operating system login. This is something that largely affects companieswhere customer information, trade secrets and other sensitive information can becompromised. A classic solution to the problem is encryption of individual files, but ithas some drawbacks as it puts a great responsibility on the users and unencryptedinformation can be left by mistake. A better solution to the problem is transparentencryption of the entire hard disk, i.e. that encryption and decryption of informationis performed automatically and without the user being affected.

Koldioxidhaltig biogas som fordonsbränsle : Lagring och förbränning vid gårdsproduktion

Biogas har anva?nts som fordonsbra?nsle i Sverige sedan bo?rjan av 90-talet som ett fo?rnyelsebart alternativ till naturgas. Fo?rst till bussflottor och sedan slutet av 90-talet a?ven till personbilar. Biogasproduktionen i Sverige har sedan slutet av 90-talet varit omkring 1,5 TWh per a?r.

Validation of rumination measurement equipment and the role of rumination in dairy cow time budgets

Automatic rumination measuring can be applied as a health indicator in dairy farming but is also highly desirable for research purposes. This study aimed to validate the technical functionality of the product RuminActTM, which employ acoustics to monitor rumination duration. The time budget of high yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The validation was performed with direct observations that were compared to the automatically recorded rumination durations.

Vattenflödets betydelse för fångster av lekvandrande lax (Salmo salar) och öring (Salmo trutta) : En utvärdering av laxfällan vid vattenkraftverket i Forshaga

Many watersheds have lost stocks of migrating fish species because of the development of hydroelectric plants and other fragmenting barriers. The remaining stocks of migrating Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in River Klarälven, Sweden are five times smaller compared to one hundred years ago. A fish-trap at the hydroelectric plant in Forshaga has been vital for the continued existence of the stocks. This is the first hydroelectric plant of eight, blocking the way to the spawning grounds. Spawners are collected in the trap for both hatchery and transport by truck upstream and past seven more hydroelectric plants to the spawning grounds, where they are released for possible natural reproduction.

D?lig st?mning i kyldisken? Konsumentens uppfattning av Oatlys marknadsf?ring

Inledning: Som svar p? den l?nga traditionen av mejerikonsumtion producerar varum?rket Oatly alternativa produkter framst?llda p? havre (Oatly, u.?). I ett samh?lle som k?nnetecknas med h?rd konkurrens mellan f?retag och ett marknadsf?ringsklimat med medvetna och kr?vande konsumenter ?r det sv?rt att sticka ut och positionera sig (Hamzah et al, 2014). Oatly anser sig vara en drivande akt?r (Oatly, u.?) i debatten kring mejeriprodukters klimatp?verkan och har en m?ls?ttning att f?r?ndra beteenden i syfte att minska konsumtion av dessa produkter.

Dammen i Slottsskogen. F?rekomst och f?ruts?ttningar samt ?tg?rdsf?rslag f?r att gynna groddjur i framtida naturv?rdsarbete.

Groddjur (amfibier) ?r viktiga indikatorarter i b?de akvatiska och terrestra ekosystem, men globalt hotas denna organismgrupp av habitatf?rlust, f?rs?mrad vattenkvalitet och klimatf?r?ndringar. Stadsmilj?f?rvaltningen i G?teborg jobbar st?ndigt med att bevara biodiversiteten i den urbana parken Slottsskogen och att gynna groddjursdiversiteten ?r en del av detta arbete. Denna studie unders?ker groddjursdiversiteten i Stora dammen i Slottsskogen med syfte att kartl?gga artdiversiteten, att bed?ma dammens l?mplighet som groddjurslokal och att ge ?tg?rdsf?rslag till Stadsmilj?f?rvaltningen f?r att gynna groddjuren i Stora dammen i framtida naturv?rdsarbete. Hypotesen var att f?rekomsten av vanlig groda (Rana temporaria), vanlig padda (Bufo bufo), st?rre vattensalamander (Triturus cristatus), mindre vattensalamander (Lissotriton vulgaris) och ?tlig groda (Pelophylax esculentus) skulle observeras. N?rvaro av amfibier indikerar p? h?lsosamma ekosystem och god biodiversitet vilket ing?r i Slottsskogens m?l.

Yttrandefrihet kontra lojalitetsplikt : Vilken princip väger tyngst när det kommer till kritiska uttalanden om arbetsgivaren via sociala medier

In this paper, the legal situation regarding freedom of expression versus the duty of loyalty is investigated, this in a context where an employee makes critical statements about his employer through social media.The duty of loyalty is a part of all employment relationships and it follows implicit from the contract regardless of whether it is specified in it or not. This duty means that an employee is required to put the employer's interests before his own and avoid all situations that end up in collision of the duties. The employee may no t either act in such a way that is intended to harm the employer. This means that the employee must be even off duty careful not to appear disloyal to the employer. This may lead to that a status update on Facebook, even when made on the employee's free time, can be regarded as disloyal conduct, with the dismissal or disciplinary action as a result.Case law states that the point of departure regarding criticizing the employer must be that the employee has an extensive such a possibility to that, without that being considered as disloyal conduct.

Perkolationsfilter : En undersökning av reningseffekt med avseende på järn och mangan

This master thesis has been done in cooperation with Sweco Viak AB in Sundsvall. The aimwith the project is to investigate the purifying effect of percolation filter due to iron andmanganese. The overall goal was to investigate how the parameters surface load,sandfractions, and burden time affect the purifying effect. The expectation is to optimize thedesign and find a demouldning of the filter that gives sufficient purifying with a highersurface load. As an attempt to accelerate the curing of the filter, experiments with a layer ofsand which surface has been covered with manganese ore (MnO2) on top of the filter havebeen done.As test filters 10 L bars were used and the experimental work was performed at thewaterworks in Hassela and Munkbysjön.In Hassela different sandfractions were tested.
