2. 1. Evaluation of Innovative Rehabilitation Technologies Utilising Polymer Composites for Aging Sewer Systems

   Author : Parastou Kharazmi; Folke Björk; Tord af Klintberg; Tor Broström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : Water and wastewater sewer system maintenance is among the costliest aspects of infrastructure investment. The replacement of deteriorated lines is a difficult and expensive process that causes community disturbance and is generally not conducted fast enough to meet demand. READ MORE

4. 2. Exploration of Graphene-like 2D Materials for Energy Management and Interface Enhancement Applications

   Author : Ya Liu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Application; Graphene-like 2D materials; Interface Enhancement; Energy Management;

   Abstract : Ever since the discovery of graphene in 2004, graphene-like 2D materials and their derivatives have attracted extensive investigations because of their exceptional physical and chemical properties. At present, the study of graphene-like 2D materials is at a stage where most of their outstanding physical and chemical properties have been discovered, but the technology for incorporating them into practical commercial products is rarely revealed.

5. 3. Automated Production Technologies and Measurement Systems for Ferrite Magnetized Linear Generators

   Author : Tobias Kamf; Mats Leijon; Jonas Öhr; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial robotics; automation; self-sensing; calibration; ferrite; linear generator; wave energy; offshore; measurements; electronics; kinetic energy storage; reluctance motor; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : The interest in breaking the historical dependence on fossil energy and begin moving towards more renewable energy sources is rising worldwide. This is largely due to uncertainties in the future supply of fossil fuels and the rising concerns about humanity’s role in the currently ongoing climate changes. READ MORE

6. 4. Cracking in concrete : crack prevention with air-cooling and crack distribution with steel fibre reinforcement

   Author : Patrik Groth; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Abstract : This Licentiate Thesis consists of four parts. The first two parts, paper A and B, deal with air-cooling by means of embedded pipes in order to reduce thermal cracking in concrete structures. These two papers are submitted for publication to RILEM Journal; ‘Materials and Structures'. READ MORE

7. 5. Particulate phosphorus accumulation and net retention in constructed wetlands receiving agricultural runoff : Critical analysis of factors affecting retention estimates

   Author : Karin Johannesson; Karin Tonderski; Stefan Weisner; Uno Wennergren; Ben Surridge; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phosphorus retention; constructed wetlands; agriculture; sampling strategy;

   Abstract : Övergödning är ett allvarligt miljöproblem, som bland annat orsakar omfattande blomningar av alger och blågrönbakterier. I söt- och brackvatten är fosfor ofta det mest begränsande näringsämnet för dessa organismer, varför en minskning av fosfortillförseln är nödvändig för att nå förbättringar. READ MORE
