1. 16. Early Involvement of Industrial Designers in Product Development: Exploring Motives and Challenges

   Författare :Lisa Carlgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Customer understanding; Capability; Front end; Collaboration; Product development; Facilitation; Industrial design;

   Sammanfattning : The ability to develop and market products that customers value determines a firm’s competitiveness, and product development that aims at competitive advantage must addressdevelopment efficiency in a conscious way. From a strategic point of view, improvements in the early phases of product development, before a development project is launched, areemphasized, and there is a need to study the best way to organize front end teams, and what personal qualities are likely to facilitate front end performance.

3. 17. Linearity Enhancements of Receiver Front-end Circuits for Wireless Communication

   Författare :Mohammed Abdulaziz; Institutionen för elektro- och informationsteknik; []
   Nyckelord :CMOS; receivers; operational transconductance amplifiers; filtering; channel select filters; stability; low noise amplifiers; linearization; carrier aggregation; spectrum sensing;

   Sammanfattning : Technology scaling in advanced CMOS nodes has been very successful in reducing the cost and increasing the operating frequency, however, it has also resulted in reduced transistor intrinsic gain and increased thermal noise coefficient, and most importantly, deteriorated linearity performance. At the same time, advanced wireless communication standards offer ever increasing data rates and pose more stringent requirements on coexistence, leading to very stringent linearity requirements.

4. 18. Ultra-wideband Millimeter-wave Antenna Arrays and Front-end Systems : For high data rate 5G and high energy physics applications

   Författare :Imran Aziz; Dragos Dancila; Ville Viikari; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The demand for wireless data communications is rapidly increasing due to several factors including increased internet access, increasingly growing number of mobile users and services, implementation of the Internet of Things (IoT), high-definition (HD) video streaming and video calling. To meet the bandwidth requirement of new and emerging applications, it is necessary to move from the existing microwave bands towards millimeter-wave bands. LÄS MER

5. 19. System-on-package solutions for multi-band RF front end

   Författare :Xinzhong Duo; Li-Rong Zheng; Kari Halonen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chip-package co-design; multi-band radio; system-on-package; Electronic structure; Elektronstruktur;

   Sammanfattning : Advances in microelectronics technology have enabled us to integrate a complex electronic system (such as a radio) on a single chip or in a single package module, known as system-on-chip (SoC) and system-on-package (SoP) paradigms. This brings not only new opportunities for system integration, but also challenges in design and implementation. LÄS MER

7. 20. Managing the fuzzy front end of product and process development : case studies of process firms

   Författare :Monika Kurkkio; Maria Elmqvist; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Redovisning och styrning; Accounting and Control;

   Sammanfattning : This thesis addresses different aspects of how to manage product development and process development. Two research studies have been conducted, both within the process industry. LÄS MER
