Split Supplies Vs. Single Supply All op amps have two power pins. In most cases, they are labeled VCC + and VCC-. Sometimes, however, they are labeled VCC and GND. This is an attempt on the part of the data sheet author to categorize the part as a split-supplies or single-supply part. It does not mean, however, that the op amp has to be operated that way. It may or may not be able to operate fr...

In these notes, we present a methodology for verifying C code, i.e. proving mechanically that it meets its functional specifications. We target C because it is (along with C++) the the language of choice for writing “important” software (operating system kernels, device drivers, compilers, etc.). The methodology has been developed for VCC, a verifier for concurrent C code. VCC and papers about ...

Aims: To evaluate different algorithms used to analyse retinal nerve fibre layer thickness (RNFL) data obtained by scanning laser polarimetry, in order to compare their relative abilities to discriminate between patients with glaucomatous localised nerve fibre layer defects and normal subjects. Methods: 48 eyes of 48 glaucomatous patients with localised RNFL defects and 53 eyes of 53 healthy su...

Recently, as vehicle computing technology has advanced, the paradigm of the vehicle has changed from a simple means of transportation to a smart vehicle for safety and convenience. In addition, the previous functions of the Intelligent Transportation System (ITS) such as traffic accident prevention and providing traffic volume information have been combined with cloud computing. ITS services pr...

BACKGROUND Vibrio cholerae is the causal intestinal pathogen of the diarrheal disease cholera. It secretes the protease PrtV, which protects the bacterium from invertebrate predators but reduces the ability of Vibrio-secreted factor(s) to induce interleukin-8 (IL-8) production by human intestinal epithelial cells. The aim was to identify the secreted component(s) of V. cholerae that induces an ...

Software Product Line Engineering (SPLE) is a successful paradigm to produce a family of products for a specific domain. A challenge in SPLE is to check that different models used in early SPL specification do not contain inconsistent information that may be propagated and generate inconsistent products that do not conform to its requirements. This challenge is difficult to address due to the h...

Pore-forming toxins (PFTs) are a distinct class of membrane-damaging cytolytic proteins that contribute significantly towards the virulence processes employed by various pathogenic bacteria. Vibrio cholerae cytolysin (VCC) is a prominent member of the beta-barrel PFT (beta-PFT) family. It is secreted by most of the pathogenic strains of the intestinal pathogen V. cholerae. Owing to its potent m...

version of the witness predicate is translated to Isabelle/HOL and Theorem 1 is proved there. gives us enough expressiveness to quantify over graphs, labellings, etc. and simplifies the translation to other proof systems. For verifying the mathematical part, we resort to Isabelle/HOL, a higher-order-logic interactive theorem prover [17]. We do so, since it has a large set of already formalized ...

This paper presents the performance assessment and working fluid selection for a novel integrated vapor compression cycle-organic Rankine cycle system (i-VCC-ORC), which recovers ultra-low-temperature waste heat rejected (50 °C) by condenser of (VCC). The analyses are carried out refrigeration capacity (heat input) 35kW along with component sizing organic (ORC). effects operational parameters o...
