In this study I have investigated the various factors influencing reproductive tactics among breeding blue tits (Parus caeruleus). The study was carried out in a nestbox-breeding population of marked individuals at the Revinge Area, outside Lund, southern Sweden. I have especially investigated the energetic, physiological and temporal factors influencing the reproductive decisions. This included u

Varje program och kurs på Lunds universitet skall få en genuscertifieringsstämpel. Universitetets lärare skall tvingas vara genusmedvetna och bland de studerande skall det finnas en genusombudsman. Professor Tiina Rosenberg vid Centrum för genusvetenskap har initierat en ny form av kontroll och härskarteknik, forkortat utgave i Sydsvenskan 19.okt08.

Wireless communication using very-large multiple-input multiple-output (MIMO) antennas is a new research field, where base stations are equipped with a very large number of antennas as compared to previously considered systems. Unlike the conventional small and compact antenna arrays, the very-large arrays may span many wavelengths in space, thus they can experience large-scale fading over the arr

Tjänster som Lexbase verkar göra oss alla till präktiga stalkare. När informationsöverflödet kommer så nära tycks mångas omdöme stängas av. Enligt devisen ”kan man, så ska man” släpper vi all rim och reson och börjar sedan lexbejsa den skumme grannen, kompisens nye kille eller kanske chefen.

Since the 1990s, it has often been argued that the earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, for instance, with its largely depleted resources and an indigenous population which almost became extinct in the 19th century, has been seen as a microcosmic warning about what may happen to our entire planet. However

De i västerländsk musik vanligast förekommande instrumenten - från blockflöjtsfamiljen till hela slagverket - presenteras i omfångstabeller. Vidare finns kortfattad sammanställning av "svåra" greppväxlingar, svårspelade lägen, tekniska finesser, sordineringar, olika spelarter m.m.

Popular Abstract in Swedish Målet med arbetet var att öka mängden vindkraft, solel och annan distribuerad generering (DG) som kan anslutas till befintliga distributionsnät på ett snabbt och kostnadseffektivt sätt. Att införa aktiv spänningsreglering i nätet, istället för installation av nya ledningar, har identifierats som en lämplig strategi. Då denna princip bygger på att DG-enheternas produktioDistributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. Voltage control in these networks is often limited to the on-load tap change

We approach the simultaneous localization and mapping problem by using an ultrasound sensor and wheel encoders on a mobile robot. The measurements are modeled to yield a conditionally linear model for all the map states. Moreover, we implement a Rao-Blackwellized particle smoother (RBPS) for jointly estimating the position of the robot and the map. The method is applied and successfully verified b
