Whenever engineers who need or use isolation amplifiers get together and talk about the improvements they would like to see most, the big three—cost, size, performance—are likely to be mentioned. The industrial or medical equipment manufacturer often has to make a choice of either buying an isolation amplifier or building his own. Cost is the key criterion for such a decision, but there are oth...

One of the benefits of software product line approach is to improve time-to-market. The changes in market needs cause software requirements to be flexible in product lines. Whenever software requirements are changed, software architecture should be evolved to correspond with them. Therefore, domain architecture should be designed based on domain requirements. It is essential that there is trace...

Traumatic intracranial aneurysms (TICAs) are rare and are associated with high rates of morbidity and mortality. TICAs usually result from head injuries caused by traffic accidents, industrial accidents, or gunshots. We report a traumatic aneurysm of the callosomarginal artery-cortical artery junction arising from a penetrating injury by scissors. A 51-year-old woman was admitted to our hospita...

In this paper, we obtain a sucient condition for boundedness of composition operators betweenweighted spaces of holomorphic functions on the upper half-plane whenever our weights are standardanalytic weights, but they don't necessarily satisfy any growth condition.

In this paper we describe the successful application of the ProB validation tool on an industrial case study. The case study centres on the San Juan metro system installed by Siemens. The control software was developed and formally proven with B. However, the development contains certain assumptions about the actual rail network topology which have to be validated separately in order to ensure ...

I test the hypothesis that the mobility of scienti…c and technical personnel is a conduit for knowledge spillovers among innovative …rms. Using a variant of the standard Tobin’s Q equation, I show that …rms who have access to large pools of externally created knowledge in their industrial and technological neighborhoods enjoy additional market value as a result of higher scienti…c labor mobilit...

In this chapter, we describe the successful application of ProB on industrial projects realized by Siemens. Siemens are successfully using the B-method to develop software components for zone controller and carbonne controller of CBTC systems. However, the development contains certain assumptions about the actual rail network topology which have to be validated separately in order to ensure saf...

The demand for enzymes in the global market is projected to rise at a fast pace in recent years. There has been a great increase in industrial applications of pectinase owing to their significant biotechnological uses. For applying enzymes at industrial scale primary it is important to know the features of the enzyme. Thus, this study was undertaken with aims of characterizing the pectinase enz...
