Waste in form of fat, oil and grease (FOG) is generated where food is prepared or consumed, e.g. in households. If collected properly, the household FOG could be interesting for biogas production. This fraction has been source-separated and collected separately in a residential area in Malmö, Sweden. The biogas potential has been evaluated by mesophilic digestion experiments. Both single-substrate
Iii analysis-by-synthesis linear predictive coding (AbS-LPC) an LPC synthesis filter is combined with an analysis-by-synthesis search of the excitation signal. The synthesis filter is an estimator for the speech signal given the excitation. However in most AbS-LPC algorithms this estimator has no explicit model of the quantization noise, which is present in the excitation signal. This paper descri
In this paper we look at opportunities to support the creation of value for all through the use of end-user-owned Virtual Personal Assistant. We use a chat-bot as example of technology with a possibility for transferring and diffusing new functionality, features and capabilities. This category of software can create potential value through its AI and natural language processing combined with emula
Protection against mucosally transmitted infections probably requires immunity at the site of pathogen entry(1), yet there are no mucosal adjuvant formulations licensed for human use. Polyethyleneimine (PEI) represents a family of organic polycations used as nucleic acid transfection reagents in vitro and DNA vaccine delivery vehicles in vivo(2,3). Here we show that diverse PEI forms have potent m
OBJECTIVES: To determine wild-type minimum inhibitory concentration (MIC) distributions for Mycobacterium tuberculosis, as the background data for defining susceptibility breakpoints are limited. METHODS: We determined wild-type MIC distributions of M. tuberculosis using a 96-stick replicator in Middlebrook 7H10 (7H10) medium for ethionamide (ETH), prothionamide, thiacetazone, cycloserine, rifabut
In order to reduce the effort of the controller design in the customized image convolution processor, a controller synthesis tool is developed based on [9] to support the design flow from a system or algorithm specification to RTL level VHDL. Architecture extensions to basic FSMs structures are implemented with the purpose of optimizing controller design for area and power consumption. Together wi
Syftet med denna uppsats blir att ta reda på hur reformatorn Olaus Petri uttryckte sin främlingsfientlighet och mot vem eller vilka den riktades. Med främlingsfientlighet menas i denna uppsats inte bara rädsla för utlänningar utan också rädsla för det som var annorlunda trots att det betecknades som svenskt. Reformationen var inte bara en religiös och andlig företeelse. Den gjorde också anspråk på
Increasing cross-border interaction in the border regions combined with the largely state-centric legislative processes of the nation states, have unfolded a demand for border regional actors to attempt to influence the state level to change legislation, as barriers are identified for individuals and companies. Adapting a border regional perspective, the actors and organisational methods to remove
Denna uppsats diskuterar, utifrån relevant teori inom narratologin, det filmiska förstapersonsberättandet och dess konstruktion. Med utgångspukt i en synkron studie av ett antal förstapersonsfilmer (Where the Truth Lies, Millennium Mambo, The New World, The Thin Red Line, The Brown Bunny, Eyes Wide Shut och L'Intrus) diskuteras vilka implikationer dessa filmer har för filmteori rörande just de
The current research considers the approximate string matching search for important subsequences from DNA sequences, which is essential for numerous bioinformatics computation tasks. We tested several approximate string matching algorithms and furthermore developed one for DNA data. Run times of the algorithms are important, since the amount of data is very large.
Deep brain stimulation is an accepted technique for the treatment of Parkinson's disease. Deep brain stimulation affects the electrical functions of neurons and several explanations are available to describe this treatment modality. Such as depolarization blockade, synaptic inhibition, synaptic depression and stimulation induced modulation of pathological network activity. An electrical impedance
Cell surface proteins of the human gastric pathogen Helicobacter pylori, reference strain CCUG 17874, were extracted with acid glycine and fractionated by heparin affinity chromatography. The extracts were subsequently analysed using high-resolution two-dimensional gel electrophoresis (2-DE) and immunoblotting. Four proteins of low molecular masses (25-30 kDa) stained by Coomassie R-350, were iden
PIXE-analyser kan utföras med utvecklad analysuppställning med noggrannhet och precision av c:a 10 % och med hög analyskapacitet. Ett dataprogram för evaluering av räntgenspektra presenteras. Inverkan av provtjocklek vid PIXE-analys av inhomogena prov har studerats och korrektioner föreslås. Fluorinnehållet i filterprov har bestämts, samtidigt med PIXE-analys, genom utnyttjande av en kärnfysikalis
Canonical bases, also called SAGBI bases, for subalgebras of the non-commutative polynomial ring are investigated. The process of subalgebra reduction is defined. Methods, including generalizations of the standard Gröbner bases techniques, are developed for the test whether bases are canonical, and for the completion procedure of constructing canonical bases. The special case of homogeneous subalg
The ability to predict surface defects in outer panels is of vital importance in the automotive industry, especially for brands in the premium car segment. Today, measures to prevent these defects can not be taken until a test part has been manufactured, which requires a great deal of time and expense. The decision as to whether a certain surface is of acceptable quality or not is based on subject
Several physics courses are given at Lund Institute of Technology. In the basic courses on ray and wave optics, holography has played an important role both in stimulating the students to curiously investigate the optical world and as an important visualisation of some obvious and interesting parts of the courses. To meet the need for basic laboratory experience, a holographic laboratory has been
Water and salt mass balances for the Dead Sea were modeled. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production, and brine discharge were included in the models. The mixing time in the Dead Sea was modeled using a single-layer (well-mixed) a two-layer (stratified) system. Using the single-layer approach the water level was predi
In earlier work we have extended Mazo's concept of faster-than-Nyquist signaling to pulse trains that modulate adjacent subcarriers, a method we called two dimensional Mazo signaling. The signal processing is similar to orthogonal frequency division multiplex (OFDM) transmission. Despite pulses that are faster than the Nyquist limit and subcarriers that significantly overlap, the transmission achi
