The goal of the Verifying C Compiler project is to bring design by contract to C. More specifically, we are developing a verifying compiler, code name vcc, that takes annotated C programs, generates logical verification conditions from them and passes those verification conditions on to an automatic theorem prover to either prove the correctness of the program or find errors in it. C Intricacie...

Macrophages are long-lived target cells for HIV infection and are considered viral reservoirs. HIV assembly in macrophages occurs in virus-containing compartments (VCCs) in which virions accumulate and are stored. The regulation of the trafficking and release of these VCCs remains unknown. Using high resolution light and electron microscopy of HIV-1-infected primary human macrophages, we show t...

| We propose a new ipop con guration which saves about 60% of total clocking power using a half-swing clock. To use the half-swing clock, level converters or special clock drivers are traditionally required and the power consumptions of these logic cannot be ignored. In the proposed scheme, only NMOSes are clocked with half-swing clock in order to make it operate without the level converter or ...

PURPOSE Scanning laser polarimetry (SLP) enables the measurement of retinal nerve fiber layer (RNFL) thickness in vivo. As SLP measurements can be influenced by several conditions such as corneal birefringence, the new version GDx Access is implemented by the variable corneal compensator (VCC). The aim of this study was to evaluate the influence of cataract extraction and foldable intraocular l...

Purpose The different dimensions and contexts within which value is co-created has generated varied views of how understood or formed. This study aims to examine employee-guest perceived as important factors for the successful implementation co-creation (VCC). Design/methodology/approach employs an interpretive paradigm, using in-depth interviews, focus group discussions participant observation...

PURPOSE To evaluate the ability of scanning laser polarimetry with variable corneal compensation to detect progressive retinal nerve fiber layer (RNFL) loss in glaucoma patients and patients suspected of having the disease. METHODS This was an observational cohort study that included 335 eyes of 195 patients. Images were obtained annually with the GDx VCC scanning laser polarimeter, along wit...

PURPOSE To evaluate quantitatively the intraobserver reproducibility of measurements of the retinal nerve fiber layer (RNFL) in healthy subjects and an ocular hypertensive population using two nerve fiber analyzers. METHODS Sixty eyes of normal (n=30) and ocular hypertensive subjects (n=30) were consecutively recruited for this study and underwent a complete ophthalmologic examination and ach...

Introduction Digital-to-analog converters (DACs) are usually used as an interface between digital systems and continuous analog circuitry. To choose the type of DAC best suited for an application, the designer must consider many important performance measures. • Resolution: Generally, a DAC is specified by the number of bits in the input, or the input width, which represents the number of volta...

This report presents a C/C++ based system design flow that uses SpecC, VCC and SystemC tools. The design starts with a pure C model that is then converted into a SpecC model. A so-called behavior exploration task then takes place to analyze and optimize the system behavior. We then perform architectural exploration using VCC. Once this is complete, the behavior model is refined to an architectu...
