Although sandwich panels are widely used in the industry, limitations cores’ structure designs and materials restrain their use stiffness- or strength-critical applications without increasing beams’ dimensions. The of additive manufacturing over conventional fabrication methods enabled us to tune design according stiffness strength requirements overall Seven core structures were 3D printed Nylo...

During the last few years Computer Integrated Manufacturing (CIM) became an important aspect in the manufacturing industry. The di erent components of CIM as there are the CAx techniques on the engineering side and manufacturing planning and control systems (MPC-systems) on the operational side now show their in uence on organizational structures and the working environment. Limits and problems...

lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. in a more basic term, more value with less work. since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...

In this paper we propose a reject rule applicable to a Multi-Expert System (MES). The rule is adaptive to the given domain and allows the achievement of the best trade-off between reject and error rates as a function of the costs attributed to errors and rejects in the considered application. The results of the method are particularly effective since the method does not rely on particular stati...

The current day manufacturing environment is characterized by numerous challenges and changes. A typical manufacturing company faces constantly changing product volumes and mix. It is commonly recognized that traditional manufacturing systems do not fit to present market competition and a shift is needed. A great amount of research efforts has been put on looking for new manufacturing systems. ...

OBJECTIVES The purpose of this study was to evaluate the electroanatomic characteristics of left atrial tachycardia (AT) in a series of patients who underwent circumferential pulmonary vein ablation (CPVA) and to describe the ablation strategy and clinical outcome. BACKGROUND Circumferential pulmonary vein ablation is an effective treatment for atrial fibrillation. A potential midterm complic...

We examine bidding behavior in an open ascending-price auction, without a binding reserve price, in which allocation to a particular bidder imposes a common payoff-reducing externality on the remaining two bidders. An example consists of a “potential entrant” bidding for an innovation against two “incumbents”. The public good aspect to pre-empting the potential entrant is shown to result in two...

The effect of lidocaine on re-entrant ventricular arrhythmias (RVA) was studied in dogs 3-7 days following ligation of the anterior descending coronary artery; direct recordings were made of the re-entrant pathway (RP) from the epicardial surface of the infarction zone (IZ). Lidocaine in a therapeutic dose consistently prolonged refractoriness of potentially RP(s) in the IZ and produced a highe...

E-business enterprises provide personalize services for customers based on their privacy information. However, customers benefit from personalization while suffering from privacy concern. The tradeoff between consumers’ benefit function and firms’ earnings function are explored when an incumbent adopts privacy protection in perfect monopoly market. It also found that when the potential entrant ...

This paper is a qualitative study of graduate students' experiences as e-learners as reflected in papers based on their journals. The study examined what students experience as they take an online course, and how students express their buy-in or lack of buy-in to an online course. Students' initial concerns about their transition to this new environment were related to learning strategies and i...
