Health Hazards of Building Materials

There is growing concern about the possible hazards which can result from the use of certain organic building materials. The issue has received a great deal of attention in industrial countries in temperate climates, because indoor air pollution is frequent in tight, energy efficient buildings with low rates of ventilation. This is not yet a problem all over the world, but an awareness of the risk

Photoluminescence Studies of Single Quantum Dots

This thesis presents photoluminescence (PL) spectroscopy studies of single III-V semiconductor quantum dots (QDs). The electronic properties of the QDs, as well as, the dynamics of the processes taking part inside and in the surroundings of the QDs have been studied by single quantum dot photoluminescence spectroscopy, time resolved spectroscopy, and correlation spectroscopy. A detailed overview o

Model-Based Deadtime Compensation of Virtual Machine Startup Times

Scaling the amount of resources allocated to an application according to the actual load is a challenging problem in cloud computing. The emergence of autoscaling techniques allows for autonomous decisions to be taken when to acquire or release resources. The actuation of these decisions is however affected by time delays. Therefore, it becomes critical for the autoscaler to account for this pheno

Efficient Java™ monitors

In most real world systems, objects vastly out- numbers threads. This paper shows how this characteristic can be used to implement eficient JavaTMmonitors in a way that reduces the num- ber of needed monitors to be equal to the number of threads, while fulfilling the Java™synchronized semantics. Some additional benefits related to prior- ity inheritance and hierarchical resource locking will also
