• Demonstration of an enhancement in the modulation bandwidth from 16 GHz to 28 GHz in an injection locked semiconductor laser with a coincident reduction in parasitic chirp. • Demonstration of room-temperature, continuous-wave operation of the first bipolar cascade laser. This laser demonstrated an internal efficiency of 150% and a measured external modulation efficiency of 99.3%. Continuous-w...

Cross-device application development poses different requirements ranging from the adaptation and distribution of user interfaces, over the migration of application state to the management of data as it is moved around and shared between devices. In particular, the evaluation of multi-device user interfaces becomes a challenge when they are distributed across a range of interaction resources. W...

Web sites are inadequate for dealing with the software production process that involves connecting with underlying logic in a unified and systematic way. As a solution, we propose the OO-H method, an object-oriented software approach that captures relevant properties involved in modeling and implementing Web application interfaces. T he Web's characteristics—ubiquity, open standards, interlinki...

The study investigates the growth by pulsed-laser deposition (PLD) of ZnO thin films for the eventual incorporation into piezo-electric actuators and other sensors being developed at the University of Twente. All films are purely c-axis oriented, and results are presented which suggest the production of some of the highest quality ZnO thin films yet reported. These include films with rocking cu...

This paper presents a comprehensive review of diamond electronics from the RF perspective. Our aim was to find and present the potential, limitations and current status of diamond semiconductor devices as well as to investigate its suitability for RF device applications. While doing this, we briefly analysed the physics and chemistry of CVD diamond process for a better understanding of the reas...

Superconducting quantum interference devices SQUIDs have been a key factor in the development and commercialization of ultrasensitive electric and magnetic measurement systems. In many cases, SQUID instrumentation offers the ability to make measurements where no other methodology is possible. We review the main aspects of designing, fabricating, and operating a number of SQUID measurement syste...

We introduce Panelrama, a web framework for the construction of distributed user interfaces (DUI). Our implementation provides developers with low migration costs through built-in mechanisms for the synchronization of UI state and minimal changes to existing languages. Additionally, we describe a solution to categorize device characteristics and dynamically change UI allocation to best-fit devi...

Polymers acquire persistent polarization due to the alignment of dipoles and migration of charge carries over macroscopic distances. Information on the charge storage and transport phenomena in polymer electrets is of great interest for several industrial applications. The present paper is an attempt to elucidate the classification, types, mechanisms, charging methods applications and uses of E...

The wide range of applications of thermal imaging devices existing in military, industrial and space fields attract researchers to study pyroelectric materials which exhibit a temperature-dependent spontaneous polarisation. A brief review of pyroelectricity, pyroelectric materials and some commercial applications of these materials we will be given in this paper.
