1. 1. On Measurement and Analysis of Internet Backbone Traffic

   Författare :Wolfgang John; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Packet Header; Internet Backbone; Header Anomaly; Malicious Traffic; Connection Behavior; Peer-to-Peer; Measurement; Passive; Classification; Traffic Analysis;

   Sammanfattning : In the last decade, the Internet emerged undoubtedly as the key component for commercialand personal communication. The success of the Internet is mainly based on its versatilityand flexibility, allowing for the development of network applications ranging from simpletext based utilities to complex systems for e-commerce and multi-media content.

3. 2. Ultra-Wideband Time Domain Measurement Systems for Microwave Tomography

   Författare :Xuezhi Zeng; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time DomainMeasurement; Ultra-Wideband; EquivalentTime Sampling; Real Time Sampling; Microwave Tomography; Measurement Error; Frequency Domain Measurement;

   Sammanfattning : As a potential imaging modality for biomedical applications, microwave tomography has attracted a lot of interests in recent years. With microwave tomography, microwave signals are transmitted into the biological tissues and the scattered fields are recorded. LÄS MER

4. 3. Nonlinear Characterisation and Modelling of Microwave Semiconductor Devices

   Författare :Mattias Thorsell; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; noise modelling; nonlinear measurement; active load-pull; noise measurement; thermal characterisation; AlGaN GaN HEMT; nonlinear modelling;

   Sammanfattning : There is an increasing need for more accurate models taking into account the nonlinearities and memory effects of microwave transistors. The memory effects are especially important for transistor technologies suffering from relatively large low frequency dispersion, such as GaN baed HEMTs. LÄS MER

5. 4. Swedish Numerals in an International Perspective

   Författare :Magnus Olsson; tolkning i offentlig sektor och översättning danska och isländska Avdelningen för svenska; []
   Nyckelord :HUMANIORA; HUMANITIES; synchrony; round numbers; base; vacillation; parallelism; affinity; inflection; derivation; dualism; affix; language change; language planning; dates; number; measurement; typology; homonymy; semantics; syntax; phonology; morphology; designation transition; Scandinavian languages and literature; Nordiska språk språk och litteratur ;

   Sammanfattning : Swedish numerals are here treated from different points of view. The book is however not intended to be a textbook of Swedish numerals, though one may learn a great deal about the system herein - more than the general user of the language knows. Phonology, morphology, syntax and semantics all get their fair share of attention. LÄS MER

7. 5. Fibre-Optic Displacement and Temperature Sensing Using Coupling Based Intensity Modulation and Polarisation Modulation Techniques

   Författare :Johan Jason; Hans-Erik Nilsson; Bertil Arvidsson; Werner Daum; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical fibre sensor; displacement measurement; temperature measurement; fibre coupling; intensity modulation; birefringence; polarisation; OTDR; side-hole fibre;

   Sammanfattning : Optical fibre sensors are employed in the measurements of a number of different physical properties or for event detection in safety and security systems. In those environments which suffer from electromagnetic disturbance, in harsh environments where electronics cannot survive and in applications in favour of distributed detection, fibre-optic sensors have found natural areas of use.
