When a system is maintained, its automated test suites must also be maintained to keep the tests up to date. Even though practice indicates that test suite maintenance can be very costly we have seen few studies considering the actual efforts for maintenance of testware. We conducted a case study on an evolving system with three updated versions, changed with three different change strategies.
Abstract in German This book chapter discusses hetero- and homovocality in the voices of mezzasopranos and altos in opera and in popular music.
περὶ φιλίας ἕποιτ᾽ ἂν διελθεῖν· ἔστι γὰρ ἀρετή τις ἢ μετ᾽ ἀρετῆς, ἔτι δ᾽ ἀναγκαιότατον εἰς τὸν βίον. ἄνευ γὰρ φίλων οὐδεὶς ἕλοιτ᾽ ἂν ζῆν, ἔχων τὰ λοιπὰ ἀγαθὰ πάντα. Härnäst är det dags att avhandla vänskapen. Den är en sorts dygd eller förekommer tillsammans med dygden. Dessutom är vänskap det som man allra mest behöver för att leva, för utan vänner skulle ingen vilja leva, även om han hade allt m
This report focuses on the use of egress models to assess the optimal strategy in the case of total evacuation in high-rise buildings. A model case study made of two identical twin towers linked with two sky-bridges at different heights has been simulated. The towers are 50 floor high-rise buildings including both vertical and horizontal egress components, namely stairs, occupant evacuation elevat

Popular Abstract in Swedish Nervsignaler som förmedlar känsel från huden och kommandon till kroppsmuskulaturen passerar genom ryggmärgen eller dess motsvarighet i hjärnstammen. Kunskap om hur ryggmärgens nervkretsar är uppbyggda och hur de bearbetar nervsignaler är därför av fundamental betydelse för att kunna förstå och behandla exempelvis smärta och ryggmärgskador. I detta avhandlingsarbete studPrinciples for sensorimotor transformation and plasticity in the spinal cord and functional repair in the root-avulsed spinal cord were studied. A comparative study confirmed that the nociceptive withdrawal reflex (NWR) system is composed of reflex modules, with each performing a finely tuned transformation of skin sensory input to activity in one muscle. This suggests that modularity of the NWR s
Odorant Binding Proteins (OBPs) and Chemosensory Proteins (CSPs) are small soluble proteins found in the lymph of insect sensillae located on insect antennae. Odorant Binding proteins are implied in olfaction, by binding hydrophobic odorant molecules and transporting them to the olfactory receptor located on the dendrite of the olfactory neurons. They are divided into three groups, Pheromone Bindi
Popular Abstract in Swedish Grupp B streptokocker (GBS) är den vanligaste orsaken till blodförgiftning, lunginflammation och hjärnhinneinflammation i nyföddhetsperioden. Ungefär en fjärdedel av alla kvinnor är koloniserade (bärare) genitalt av GBS under graviditeten och förlossningen. Hälften av barnen till dessa kvinnor blir smittade av bakterien i samband med födseln, men bara en liten del av deInfection with group B streptococcus (GBS), an encapsulated bacterium, is an important cause of neonatal morbidity and mortality. Capsular polysaccharides and cell surface proteins of GBS are candidate antigens for development of a human GBS vaccine. Proteins have many advantages as vaccine antigens. The majority of the neonatal infections are caused by strains of capsular serotypes Ia, Ib, II, II
This thesis addresses the phase behavior and phase structure in mixed surfactant-surfactant and surfactant-polymer systems, where the co-solutes have opposite charges (catanionic systems). The initial goal has been to investigate self-assembly aspects in mixtures of single-/double-chained surfactants and bile salt/double-chained surfactants, with the main focus on vesicle assembly in dilute region
