Next generation RFID towards ubiquitous wireless sensing and identification requires high network throughput along with long operation range and ultra low energy consumption. In this paper, we review future RFID for ubiquitous intelligence and their technology needs from system to device perspectives. As a promising enabling technology, ultra wideband radio (UWB) and its use in various RFID implem
Elasticity is the ability of a cloud infrastructure to dynamically change the amount of resources allocated to a running service as load changes. We build an autonomous elasticity controller that changes the number of virtual machines allocated to a service based on both monitored load changes and predictions of future load. The cloud infrastructure is modeled as a G=G=N queue. This model is used
Katekeser är en genre som vanligtvis förknippas med lutheransk religionsundervisning, och inte revolutioner. Dess form, att ställa en antal givna frågor och ge ett definitivt svar för varje fråga synes lämna föga utrymme för självständigt och kritiskt tänkande. Frågandet som teknik är en retorik; syftet är att styra läsarens tänkande i avsedd riktning. Inpräntande av normer, inte radikala reflekti
In this contribution a constitutive model for glassy polymers is developed. To incorporate the distribution of the polymer chains, a homogenization procedure involving a chain orientation distribution function is employed. During loading the polymer chains orient in a certain manner, leading to an evolution of the macroscopic anisotropic properties. This phenomenon is modeled by use of evolution e
The need for new renewable products has enhanced the interest in cellulose and hemicellulose as raw material. The wood plant cell wall is a complex mixture of cellulose, hemicellulose, lignin and minor amounts of pectin, proteins and extractives. Several interactions between the compounds make them difficult to separate without modification. O-acetyl-galactoglucomannan (O-acetyl-GGM), the major he

Brief description of the iconographic program of the twelfth-century baptismal font in the church of Dalby.
In many organizations it is considered of vital importance to translate its vision and strategy into objectives, to determine the best means of achieving these and to review the results – with participation from all members, from management to shop floor. The objective of this study was to make a first test of a method that could be applied for verbalizing and communicating a common vision and ide
The book is an empirical ivestigation and analysis of the health situation for workers with irregular working hours in services. The anaysis is made from a different perspectives with cross-depratmenta co-operatin between researchers from 5 disciplines
A smartphone is a personal device and as such usually hosts multiple public user identities such as a phone number, email address, and Facebook account. As each smartphone has a unique Bluetooth MAC address, Bluetooth discovery can be used in combination with the user registration to a server with a Facebook account. This makes it possible to identify a nearby smartphone related to a given Faceboo
Data volumes in communication networks increase rapidly. Further, usage of social network applications is very wide spread among users, and among these applications, Facebook is the most popular. In this paper, we analyse user demands patterns and content popularity of Facebook generated traffic. The data comes from residential users in two metropolitan access networks in Sweden, and we analyse mo
