Its major products include cooking and salad oil, margarine, shortening and a full line of proteins. With stiff competitive pressure from soy manufacturers, Canbra is constantly seeking ways to increase manufacturing efficiency and reduce costs. At the company's Lethbridge, Alberta, Canada facility, it relies heavily on automation technology to control, automate and monitor production. A project to automate the batch control process at a Canadian oil processing plant has yielded significant improvements as well as a considerable amount of money. The automated solution combines the batch control software with a Flexicon bulk handling system that conveys, loads, unloads, weighs, feeds, and processes bulk solid material.","PeriodicalId":401124,"journal":{"name":"Computing & Control Engineering Journal","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125592084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But, despite their obvious advantages to patients and surgeons, the imminent widespread uptake of this technology is by no means certain. The new methodology pioneered by the Acrobot team could help to assure their adoption and determine the exact nature of future medical robots. Contrary to a public misconception that places them on the par with a scalpel-wielding RoboCop, medical robots are not going to replace humans in the operating theatre. Rather, robotic systems can be thought of as smart instruments designed to extend and complement the skills of surgeons in an ever more demanding and patient driven health service.

The objective of the modular certification and technical modularity framework is to provide certifiers with a set of processes and techniques that allow certification of modules combinations of modules or entire systems within a common framework. The module is a logical grouping of dependability specifications for the purposes of abstraction and encapsulation. The module may be implemented by physical components, software packages, or combinations of hardware and software and can include social elements as well as technical components. This approach depends upon modules that have associated dependability cases with supporting rationale and evidence of dependability as input to the certification process. The methodology offers benefits to all stakeholders concerned with proving assurance of safety and security on a programme, particularly military avionics programmes.","PeriodicalId":401124,"journal":{"name":"Computing & Control Engineering Journal","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124372192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Now a new technology is bringing the benefits of dual homing to mainstream control applications without the associated costs. Effective redundancy strategies have always been of prime importance in critical applications where a fault or failure could result in catastrophe. But today even in more standard industrial applications, the simple financial costs associated with unexpected downtime are leading increasing numbers of manufacturers to look at introducing redundant systems to deliver the high availability needed to ensure profitability. Designing and implementing high availability industrial networks has traditionally represented something of a challenge. While dual homing has long provided a conceptually simple means of achieving high levels of redundancy, actually implementing such dual homing within an Ethernet network has traditionally relied upon having the dual homing functionality within the critical node itself - a PLC, industrial controller, sensor, etc.","PeriodicalId":401124,"journal":{"name":"Computing & Control Engineering Journal","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123572903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
