We study quantization noise modeling in a low-delay vector predictive transform coder for speech signals. The coder uses a Kalman filter with a backward estimated LPC model of the speech signal combined with an additive noise model of the quantization noise. Computer simulations indicate that modeling of the quantization noise can improve the quality of the decoded speech signal. This is especiall

Birger Sjöbergs fridavisor dateras, utvecklingen inom fridadiktningen klargörs. Fridavisorna analyseras som parodier.Traditionsbakgrunden till parodin söks i folkliga visor, skillingtryck, manskörsång, i breda lager spridda dikter och visor.

Kriminalvård i frihet, frivård, har sina rötter som ett alternativ till fängelse. Men vad är det för något? Är det ett straff? Jag tittar här på straffets karaktäristiska komponenter: tiden, rummet, observationen och pinan utifrån dels Michel Foucaults disciplineringsbeskrivningar och dels intervjuer med dömda, övervakare och handläggare i frivården. Observationen existerar i hög grad, men rummet

Denna bok handlar om hur en stor litterär tradition, den engelska, gestaltats på film. Med nedslag i Tennysons klassiska dikt ”The Charge of the Light Brigade”, Lord Byrons och paret Shelleys förment liderliga leverne, litteraturen som filmatiserad propaganda under det andra världskriget, Dickens’ roman Great Expectations och Shakespeares drama Macbeth besvaras frågor om hur filmen både tillvarata

Since the European conquest of Latin America, mechanisms and justifications for unequal access to and control over natural resources have developed in tandem with racial ideologies and institutions. Conceiving race and racism as sociocultural systems that evolve historically with and through the organization of human-environment relations, this chapter considers cases in which racism supported the

The early Stone Age hunters in southern and central Finland were specialized in game species living in young deciduous forests, such as the European elk, the beaver, and the Arctic hare. Later on, the game was enriched by species associated with pine and mixed oak forests, such as the brown bear, the pine marten, the red squirrel, and the forest reindeer. In Lapland the subsistence of the early hu

Popular Abstract in English Among the forms of life found in extreme environments (e.g. high temperatures ‘thermo’ and oxygen deficient ‘anaerobe’), the thermoanaerobic bacteria emerge as a highly evolved and interesting subject of study. Bacteria living as microbial mats in decaying plant material possess a great potential not only to degrade complex biomass but also to produce special chemicals.A novel ethanol-producing thermoanaerobe Caloramator boliviensis 45BT (=DSM 22065T, =CCUG 57396T) was isolated from a hot spring of the Bolivian highlands. C. boliviensis possesses the ability to utilize a wide range of substrates and can efficiently convert hexoses and pentoses into ethanol with concomitant production of acetate, carbon dioxide and hydrogen as by-products of fermentation. However

Popular Abstract in Swedish Analytisk kemi innefattar metoder för bestämning av den kemiska sammansättningen hos prover och ämnen. En kvalitativ metod ger information om den atomära eller molekylära sammansättningen medan en kvantitativ metod ger numeriska värden på hur mycket det finns av en eller flera av de komponenter som ingår i ett prov. En kombination av de båda metoderna är ofta önskvärd dAmperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. Special emphasis was placed on the optimisation of bio
