1. A Fully Integrated Microneedle-based Transdermal Drug Delivery System
Sammanfattning : Patch-based transdermal drug delivery offers a convenient way to administer drugs without the drawbacks of standard hypodermic injections relating to issues such as patient acceptability and injection safety. However, conventional transdermal drug delivery is limited to therapeutics where the drug can diffuse across the skin barrier. LÄS MER
2. Submillimeter-Wave Waveguide Frontends by Silicon-on-Insulator Micromachining
Sammanfattning : This thesis presents novel radiofrequency (RF) frontend components in the submillimeter-wave (sub-mmW) range implemented by silicon micromachining, or deep reactive ion etching (DRIE). DRIE is rapidly becoming a driving technology for the fabrication of waveguide components and systems when approaching the terahertz (THz) frequency range. LÄS MER
3. Advanced MEMS Technology for Terahertz Frequencies
Sammanfattning : With the development of terahertz (THz) technology, a variety of application demands are growing rapidly, such as high-rate communications, THz radars, environmental monitoring, medical imaging, and space exploration. However, the fabrication, integration, and packaging techniques for THz components and systems pose great challenges for a large-scale, cost-effective production. LÄS MER
4. Silicon micromachined waveguide components for terahertz systems
Sammanfattning : This thesis presents silicon micromachined waveguide components for sub-terahertz and terahertz (THz) systems fabricated by deep reactive ion etching (DRIE). Historically the main driving force for the development of THz systems has been space-based scientific instruments for astrophysics, planetary and Earth science missions. LÄS MER
5. Coordination and control in contemporary organizations
Sammanfattning : Achieving coordination and cooperation are universal challenges to organizing. In modern organizations, the problems are the same, but solutions have changed. Hierarchies and routines operate differently as means of coordination and control in contemporary forms of organizing than in bureaucracies. LÄS MER
