Bakgrund: Trots plastfilmen negativa miljöpåverkan används den idag i hög utsträckning som förpackningsmaterial vid lastsäkring, detta då plastens materialegenskaper överträffar andra konkurrerade material. Plastfilm är ett förbrukningsmaterial, vilket gör att det inte kan återanvändas och stora mängder avfall skapas. Trots vetskapen om plastavfallets negativa påverkan på miljön läggs tonvikten på den ekonomiska aspekten när förpackningsmaterial diskuteras, medans miljön utlämnas eller har mindre fokus. Syfte: Studiens syfte är att utifrån identifierade faktorer utvärdera alternativa lastsäkringsmetoder som leder till en minskad användning av plastfilm utan att äventyra kvalitén på livsmedelsvaror under transport. Frågeställningar: (1) Vilka faktorer påverkar val av lastsäkringsmetod vid samlastade livsmedel? (2) Vilka alternativa lastsäkringsmetoder kan vidtas för att minska användningen av plastfilm i lastsäkringsprocessen? Genomförande: Denna studie motsvarar en enfallsstudie som är utförd hos Martin & Servera. Empiri insamling har främst skett via semi-strukturerade intervjuer och direkta observationer. I och med Covid-19 har även strukturerade intervjuer behövs genomföras. Utifrån observationer och intervjuer har en kartläggning av Martin & Serveras utgående logistik samt lastsäkringsprocess skett för att finna faktorer som påverkar valet av lastsäkringsmetod. Faktorerna har stått till grund vid framtagning av utvärderingskriterier, som har använts för att utvärdera alternativa lastsäkringsmetoder. De alternativa metoderna är funna genom intervjuer. Resultat: Totalt identifierades sju faktorer som påverkar val av lastsäkring metod: förpackningsformer, typ av lagersystem, lagerarbetare, krav/lagar/regleringar, typ av lastbärare, omslagsmaterialets egenskaper samt vilket typ av produkt som hanteras. Utifrån faktorerna framställdes utvärderingskriterier som sedan applicerades på fyra alternativa lastsäkringsmetoder (Plastskiva, Add-On Door Flex, 2 Kompletterande Dörrar samt Bioplastfilm). Samtliga metoder bidrog till minskad användning av plastfilm. Utifrån utvärderingskriterierna; Skydd & Stabilitet, Krav/Lagar/Reglering, Kostnad, Tidsåtgång, Miljö rekommenderas plastskivan som första alternativa lastsäkringsmetoden till plastfilm.

At request of the company Climeon, this study was made regarding transportability of skid mounted heavy machinery. The study aimed to investigate what constraining dimensions there might be when transporting by road and sea as well as necessary features that would accommo date lifting, handling, lashing and securing. A literature study was done on the topic of common load carriers and logistics with heavy transports. An interview study was conducted with employees at Climeon to learn how transports are done currently, as well as input on how transports and handling of the machinery could be of higher quality. A conceptual design was made where lifting was simulated with aid of the FEA tool in SolidWorks. An analysis of necessary lashing points was done in Matlab to verify safe transports on road and sea. A dimensional constraint study was made where dimensional breaking points were identified. Price inquiries for these were sent to a forwarding agent to attempt to quantify the cost for transporting skids of various sizes. Trucking is a good mean for transporting within Europe. Roll on-Roll off or flat rack shipping are viable options for transporting large and sensitive machinery when transport by sea is necessary. Lashing the skid could be done mainly with direct lashes in combination with rubber mats for increased friction. A machinery in this order of magnitude can be lifted with a single hook if the structural elements and the lifting eyes are placed positioned in a proper way. / På uppdrag av företaget Climeon gjordes denna studie gällande transporterbarhet av rammonterade maskiner. Studiens mål var bland annat att hitta brytpunkter för dimensionering baserat på väg- och sjötransporter, samt att ta reda på vilka funktioner som behövs för att tillgodose lyft, hantering, surrning och säkring. En literaturstudie utfördes, med fokus på olika lastbärare och logistik kring tunga transporter. För att få djupare insikt i hur transportkvaliteten kan ökas, samt samla in information kring den nuvarande transporthanteringen, utfördes en intervjustudie med anställda från företaget. En konceptuell design togs fram där lyft simulerades med hjälp av FEM-analys i SolidWorks. En analys gjordes i Matlab där nödvändiga surrningspunkter undersöktes för att verifiera säkra transporter på väg och till sjöss. En studie där dimensionella begränsningars inverkan på transportpris gjordes, prisförfrågningar skickades då till en speditör och ett försök gjordes till att kvantiera priset för olika dimensioner på ramen. Lastbil är ett bra sätt att transportera tungt maskineri inom Europa. Roll on-Roll off och flat rack de bästa sättet för transport till sjöss, för stora och ömtåliga maskiner. Maskinen kan säkras i surrningsöglor med spännband eller kedja i direkt surrning i kombination med gummimatta för ökad friktion. En rammonterad maskin i denna storleksordning kan lyftas via ett enkrokslyft om lyftöglor och ramelement är placerade på ett lämpligt vis.

The aim of this diploma thesis has been the evaluation of problems of outstandings in term of tax income and their origin and influence on the resulting economic situation of every firm, especially in the connection of payment overdue or outstanding at all. For these reasons I have taken an interest at first in instruments of securing and exacting the outstandings in judicial proceedings. More minutely I have appraised the account advancements about outstandings as well as questions of taxations. Naturally I have taken heed of amortization of debts and creation of correction amounts for them. This diploma thesis can not exhaust the whole cemplexity od the topic, but this one could perhaps be an brief manual for unexperienced, but interested persons in this regard.

Cognitive radios require spectral occupancy information in a given location, to avoid any interference with the existing licensed users. This is achieved by spectrum sensing. Existing narrowband, serial spectrum sensors are spectrally inefficient and power hungry. Wideband spectrum sensing increases the number of probable fre-quency candidates for cognitive radio. Wideband RF systems cannot use analog to digital converters (ADCs) for spectrum sensing without increasing the sampling rate and power consumption. The use of ADCs is limited because of the dynamic range of the signals that need to be sampled and the frequency of operation. In this work, we have presented a CMOS based area efficient, dedicated and scalable wideband parallel/serial spectrum sensor for cognitive radio. The key contributions of the thesis are: 1. An injection locked oscillator cascade (ILOC) for parallel LO synthesis. An area-efficient, wideband RF frequency synthesizer, which simultaneously gen-erates multiple local oscillator (LO) signals, is designed. It is suitable for parallel wideband RF spectrum sensing in cognitive radios. The frequency synthesizer consists of an injection locked oscillator cascade where all the LO signals are derived from a single reference oscillator. The ILOC is implemented in a 130-nm technology with an active area of 0.017 mm2. It generates 4 uni-formly spaced LO carrier frequencies from 500 MHz to 2 GHz. 2. A wideband, parallel RF spectrum sensor for cognitive radios has been de-signed. This spectrum sensor is designed to detect RF occupancy from 250 MHz to 5.25 GHz by using an array of CMOS receivers with envelope detec-tors. A parallel LO synthesizer is implemented as an ILOC. The simulated sensitivity is around -25 dBm for 250 MHz wide bandwidth. 3. A mitigation technique for harmonic downconversion in wideband spectrum sensors. The downconversion of radio frequency (RF) components around the harmonics of the local oscillator (LO), and its impact on the accuracy of white space detection using integrated spectrum sensors, is (are) studied. We propose an algorithm to mitigate the impact of harmonic Down conversion by utilizing multiple parallel downconverters in the system architecture. The proposed algorithm is validated on a test-board using commercially avail-able integrated circuits (IC) and a test-chip implemented in a 130-nm CMOS technology. The measured data shows that the impact of the harmonic down-conversion is closely related to the LO characteristics, and that much of it can be mitigated by the proposed technique. 4. A wideband spectrum sensor for narrowband energy detection. A wideband spectrum sensing system for cognitive radio is designed and implemented in a 130-nm RF mixed-mode CMOS technology. The system employs an I-Q downconverter, a pair of complex filters and a pair of envelope detectors for energy detection. The spectrum sensor works from 250 MHz to 3.25 GHz. The design makes use of the band pass nature of the complex filter to achieve two objectives : i) Separation of upper sideband (USB) and lower sideband (LSB) around the local oscillator (LO) signal and ii) Resolution of smaller bands within a large detection bandwidth. The measured sensitivity is close to -45 dBm for a single tone test over a bandwidth of 40 MHz. The measured Image reject ratio (IRR) is close to 30 dB. The overall sensing bandwidth is 3.5 GHz and the overall wideband detection bandwidth is 250 MHz which is partitioned into 40 MHz narrowband chunks with 8 such overlapping chunks.

The aim of my thesis was to clarify the basic concepts and calculations in the area of reliability of power distribution, as an important element for increase the quality of supplied electric power, this issue we examined in Chapter 3. In the previous chapter, we explained the fundamental solution of MV networks in the Czech Republic and Germany. In Chapter 4 we explained the difficulties in evaluating their values and comparisons between distributional companies, which follows that there should be a uniform procedure for the storage and collection of data for power outages. And the individual distribution companies should follow this standard.
