Passive houses in Sweden - Experiences from design and construction

The sector of residential buildings and service organizations uses 36% of the total energy in Sweden. In June 2006, it was decided by the Swedish parliament that the energy use in residential buildings and premises should decrease by 20% per heated unit area before 2020. To reach this goal, more energy efficient buildings must be produced as well as energy efficient improvements must be performed

Mammalian Molecular Systematics with Emphasis on the Insectivore Order Lipotyphla

Insectivore classification has been one of the most controversial problems in mammalian systematics. Evolutionary relationships among the six extant families, Talpidae (moles), Soricidae (shrews), Erinaceidae (hedgehogs), Tenrecidae (tenrecs), Chryosochloridae (golden moles), and Solenodontidae (solenodons), have remained uncertain based on morphological data. Animals classified within the order L

Development of a Novel Method for Evaluation of Interfacial Tension between Polymer Melts

A novel method for the evaluation of interfacial tension of high viscosity polymer melts is described. The method involves the tracking of the shape evolution of a highly deformed droplet of one material imbedded in a second one. This makes it possible to determine the interfacial tension over a relatively short time period. The imbedded material is initially either a fiber or a disk. The techniqu

Revisiting Software Requirements Specifications - What could we learn

A software requirements specification (SRS) is an important document that reports the result from the system requirements determination (SRD) which forms a basis for subsequent activities in the systems development process. In order to increase the knowledge base of SRS and how they could be structured nine SRSs are analyzed. The analysis aims at demonstrate similarities and differences in SRS com

42 volumes of early printed sermons (incunabula) reproduced in full on microfiche. Most of the sermons are in Latin, but two volumes are in German. This Unit is a supplement to Units 31-33 (Sermons: Parts I-III) published in the year 2000.

Volume of fluid and immersed boundary investigations of a single rising droplet

(IB) methods are two popular computational techniques for multi-fluid dynamics. To help shed light on the performance of both techniques, we present accuracy assessment including interfacial geometry, detailed and global transport characteristics. The investigations include the simulations of a droplet under static equilibrium and a droplet rising due to gravity for Re≤1000. Different surface tens

Extracting Cylinder Individual Combustion Data from a High Precision Torque Sensor

A high precision torque sensor is used for extracting combustion timing information from cylinder individual pressure estimates constructed from the torque measurements. A combination of physics-based and data driven modeling is used where the physical part of the model is based on equations describing contributions of inertial and gas forces while the flexing of the crankshaft, which has rather c
