designing a fast locking pll

a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...

A Light-weight UIMS

We built a limited but successful user interface management system named HYPE which supports rapid interactive creation and organization of user interfaces for a large class of applications. HYPE is targeted at applications for which the user interface is only loosely coupled to the application. Examples of this class of application are ‘command line-driven’ programs. Many applications in this ...

Parametric study on thrust force of core drill

Drilling-induced delamination is among the major concerns of applying the fiber-reinforced composite materials in various industries. Core drill ossesses the advantage for reducing the delamination by distributing the drilling thrust force toward the drill periphery. The thrust force of core rill varying with the conditions in drilling carbon fiber reinforced plastic (CFRP) is experimentally in...

Ultrasonic Planetary Core Drill: Overview and Results from Field Trial

In the effort to explore the subsurface of terrestrial bodies, we seek to obtain better samples from ever greater depths. Many organisations are working towards technologies that can achieve this goal whilst ensuring compatibility with the likely requirements of planetary landers in terms of mass, power, and dimensions. The Ultrasonic Planetary Core Drill (UPCD) was an FP7 funded project which ...

Calculation of Bedding Angles Inclination from Drill Core Digital Images

In this paper, we describe a new technique for the automatic orientation of bedding in drill core from digital images. Images are planar pictures of the drill core, and we show that it is possible to determine layer orientation without rotating the core on the full circumference. More precisely, we show that angle information can be extracted by applying image processing and a mathematical desc...
