2. 1. Mapping and functional characterization of candidate genes and mutations for chicken growth : an approach combining computational genetics and bioinformatics

   Author : Muhammad Ahsan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Knowledge of the genetics related to growth is important for breeding chickens with the desired traits of rapid and efficient growth. A long-term selection experiment in the domestic chicken (Gallus gallus) has resulted in two highly divergent lines selected for juvenile body weight. READ MORE

4. 2. An Integrated Approach towards Model-Based Mechatronic Design

   Author : Ahsan Qamar; Jan Wikander; Hans Vangheluwe; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mechatronics; mechatronic design; development process; conceptual design; model-based systems engineering MBSE ; model integration; SysML; model-driven engineering; consistency; Industrial engineering and economy; Industriell teknik och ekonomi; Software engineering; Programvaruteknik; Systems engineering; Systemteknik;

   Abstract : Mechatronic design is an enigma. On the one hand, mechatronic products promise enhanced functionality, and better performance at reduced cost. On the other hand, optimizing mechatronic design concepts is a major challenge to overcome during the design process. READ MORE

5. 3. Model and Dependency Management in Mechatronic Design

   Author : Ahsan Qamar; Wikander Jan; Carl During; Kristina Shea; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dependency Modeling; Model-Based Systems Engineering MBSE ; Mechatronic Design; Model Integration; Tool Integration; Common Language; Mechatronic Challenges; Domain Specific Language.;

   Abstract : Managing consistency is a major concern in the design of complex engineering systems. At times, inconsistencies may lead to wrong decisions, resulting in design flaws which can compromise safety and cause failures. One cannot forget the 1999 NASA unmanned MARS Climate Orbiter, which was destroyed due to use of inconsistent units by design teams. READ MORE
