Information sharing in procurement occurs in rich and varied industry contexts in which managerial decisions are made and organizational strategy is formulated. We explore how information sharing ought to work in procurement contexts that involve investments in inter-organizational information systems （IOS） and collaborative planning, forecasting and replenishment （CPFR） practices. How and under what circumstances does a firm that plays the role of a supply chain buyer decide to share information on key variables, such as point-of-sale consumer demand data with its supplier, up the supply chain？ This is a key issue that crosses the boundary between supply chain management and information systems （IS） management. The answers that we provide are based on our use of a game-theoretic signaling model of buyer and supplier strategy in the presence of uncertainties about final consumer demand. We also explore the connection between operational costs that are associated with the firm＇s information sharing and information withholding strategies. Our results provide normative guidance to supply chain buyers about how to interpret different demand uncertainty scenarios to improve their decisions and generate high value. From the IS management perspective, we show the impacts on the firm of different information sharing approaches that are made possible by present day technologies.

An Empirical Study on the Impact of Automation on the Requirements Analysis Process

引用

Journal of Computer Science & Technology 2007年第3期22卷 338-347页

作者： Giuseppe Lami robert W.Ferguson Istituto di Scienza e Tecnologie dell'Informazione"Alessandro Faedo" 1-56124 Pisa Italy Software Engineering Institute Carnegie Mellon University 15213 PittsburghPAU.S.A.

Requirements analysis is an important phase in a software project. The analysis is often performed in an informal way by specialists who review documents looking for ambiguities, technical inconsistencies and incomplete parts. Automation is still far from being applied in requirements analyses, above all since natural languages are informal and thus difficult to treat automatically. There are only a few tools that can analyse texts. One of them, called QuARS, was developed by the Istituto di Scienza e Tecnologie dell＇Informazione and can analyse texts in terms of ambiguity. This paper describes how QuARS was used in a formal empirical experiment to assess the impact in terms of effectiveness and efficacy of the automation in the requirements review process of a software company.

COMPARING TWO CLUSTERING-BASED TECHNIQUES TO TRACK MOBILE NODES IN INDUSTRIAL WIRELESS SENSOR NETWORKS

引用

Journal of Systems Science and Systems Engineering 2016年第2期25卷 177-209页

作者： Mohammad Gholami robert W. Brennan Department of Mechanical and Manufacturing Engineering Schulich School of Engineering University of Calgary Calgary Alberta Canada T2N 1N4

Tracking mobile nodes in dynamic and noisy conditions of industrial environments has provided a paradigm for many issues inherent in the area of distributed control systems in general and wireless sensor networks in particular. Due to the dynamic nature of the industrial environments, a practical tracking system is required that is adaptable to the changes in the environment. More specifically, given the limited resources of wireless nodes and the challenges created by harsh industrial environments there is a need for a technique that can modify the configuration of the system on the fly as new wireless nodes are added to the network and obsolete ones are removed. To address these issues, two cluster-based tracking systems, one static and the other dynamic, are proposed to organize the overall network field into a set of tracking zones, each composed of a sink node and a set of corresponding anchor nodes. To manage the wireless nodes activities and inter and intra cluster communications, an agent-based technique is employed. To compare the architectures, we report on a set of experiments performed in JADE （Java Agent Development Environment）. In these experiments, we compare two agent-based approaches （dynamic and static） for managing clusters of wireless sensor nodes in a distributed tracking system. The experimental results corroborate the efficiency of the static clusters versus the robustness and effectiveness of the dynamic clusters.

Prevention of vascular structural changes with antihypertensive therapy

中国药理学与毒理学杂志 1992年第1期6卷 8-13页

作者： robert MKW LEE Hamilton Ontario Canada L8S 4J9 McMaster University Smooth Muscle Research Programme and Department of Anaesthesia

The primary aim of antihypertensive therapy is to reduce or normalize blood pressure of the patients, so that we can lower the incidence of morbidity and mortality which are related to cardiovascular complications due to hypertension. It is also desirable that antihypertensive treatments can prevent or reverse cardiovascular changes, so that after a certain treat ment period, it may be possible to withdraw the treat ments without the risk of hypertension. However, most studies to date have shown that withdrawal of treat ments usually resulted in rebound hypertension, with the re-establishment of hypertension within a very

Engineering the Smart Factory

引用

Chinese Journal of Mechanical Engineering 2016年第6期29卷 1046-1051页

作者： HARRISON robert VERA Daniel AHMAD Bilal Warwick Manufacturing Group University of Warwick

The fourth industrial revolution promises to create what has been called the smart factory. The vision is that within such modular structured smart factories, cyber-physical systems monitor physical processes, create a virtual copy of the physical world and make decentralised decisions. This paper provides a view of this initiative from an automation systems perspective. In this context it considers how future automation systems might be effectively configured and supported through their lifecycles and how integration, application modelling, visualisation and reuse of such systems might be best achieved. The paper briefly describes limitations in current engineering methods, and new emerging approaches including the cyber physical systems （CPS） engineering tools being developed by the automation systems group （ASG） at Warwick Manufacturing Group, University of Warwick, UK.

Advances in local ablation of malignant liver lesions

引用

World Journal of Gastroenterology 2016年第15期22卷 3885-3891页

作者： robert M Eisele Department of General Visceral Vascular and Pediatric Surgery Medical Faculty of the University of Saarland

Local ablation of liver tumors matured during the recent years and is now proven to be an effective tool in the treatment of malignant liver lesions. Advances focus on the improvement of local tumor control by technical innovations, individual selection of imaging modalities, more accurate needle placement and the free choice of access to the liver. Considering data found in the current literature for conventional local ablative treatment strategies, virtually no single technology is able to demonstrate an unequivocal superiority. Hints at better performance of microwave compared to radiofrequency ablation regarding local tumor control, duration of the procedure and potentially achievable larger size of ablation areas favour the comparably more recent treatment modality; image fusion enables more patients to undergo ultrasound guided local ablation; magnetic resonance guidance may improve primary success rates in selected patients; navigation and robotics accelerate the needle placement and reduces deviation of needle positions; laparoscopic thermoablation results in larger ablation areas and therefore hypothetically better local tumor control under acceptable complication rates, but seems to be limited to patients with no, mild or moderate adhesions following earlier surgical procedures. Apart from that, most techniques appear technically feasible, albeit demanding. Which technology will in the long run become accepted, is subject to future work.

Electroless copper plating using dimethylamine borane as reductant

引用

Particuology 2012年第4期10卷 487-491页

作者： Yong Liao Shengtao Zhang robert Dryfe College of Chemistry&Chemical Engineering University of ChongqingChongqing 400044China School of Chemistry The University of ManchesterManchester M139PLUK

Electroless copper plating was studied using dimethylamine borane （DMAB） as reductant and 1,5,8,12- tetraazadodecane as additive and triethanolamine （TEA） as buffer. The effects of pH, temperature and concentrations of reactants and additives on the anodic oxidation of DMAB and the cathodic reduction of copper ion were investigated. Experimental results indicate that high pH values （10-12.5） promote the oxidation of DMAB, and suppress the reduction of the copper ion, while high bath temperatures （55-70℃） accelerate both anodic oxidation and cathodic reduction. Increase of the Cu2＋and DMAB concentrations can improve the deposition rate of copper plating. Results for a dual-chelating-agent system indicate that 1,5,8,12-tetraazadodecane plays an important role in chelation, while the main effect of TEA is adsorption on copper surfaces to inhibit DMAB oxidation and to promote deposition.
