A Hybrid 3D Learning-and-Interaction-based Segmentation Approach Applied on CT Liver Volumes
M. Danciu,M. Gordan,C. Florea,R. Orghidan
Radioengineering , 2013,
Abstract: Medical volume segmentation in various imaging modalities using real 3D approaches (in contrast to slice-by-slice segmentation) represents an actual trend. The increase in the acquisition resolution leads to large amount of data, requiring solutions to reduce the dimensionality of the segmentation problem. In this context, the real-time interaction with the large medical data volume represents another milestone. This paper addresses the twofold problem of the 3D segmentation applied to large data sets and also describes an intuitive neuro-fuzzy trained interaction method. We present a new hybrid semi-supervised 3D segmentation, for liver volumes obtained from computer tomography scans. This is a challenging medical volume segmentation task, due to the acquisition and inter-patient variability of the liver parenchyma. The proposed solution combines a learning-based segmentation stage (employing 3D discrete cosine transform and a probabilistic support vector machine classifier) with a post-processing stage (automatic and manual segmentation refinement). Optionally, an optimization of the segmentation can be achieved by level sets, using as initialization the segmentation provided by the learning-based solution. The supervised segmentation is applied on elementary cubes in which the CT volume is decomposed by tilling, thus ensuring a significant reduction of the data to be classified by the support vector machine into liver/not liver. On real volumes, the proposed approach provides good segmentation accuracy, with a significant reduction in the computational complexity.

Romanian Market Researches in Global Market Context
Victor Danciu
Theoretical and Applied Economics , 2006,
Abstract: Market research is a powerful industry, whose value reached 21,5 billion USD in 2004. Market studies expenses are mostly concentrated in Europe (45%) and in USA (37%). The market shares of the Top 10 companies were above fifty per cent of the research market’s turnover. As a young, modest market, which is 0,84% of the global expenses value, Romania was the global leader in terms of growth, in 2004. With an asymmetric demand and a relatively concentrated offer, the Romanian research market may have a spectacular development in the future, if the obstacles for the customers and research companies are surpassed. If so, the pressures following the UE’s entry of Romania and the evolution of customers needs and expectations will speed up the growth of the market research.
Succes on the International Market Depends on Brand Strategy
Victor Danciu
Theoretical and Applied Economics , 2006,
Abstract: Brand strategy is vital for the succes of the company on the international market. Identity and positionning are critical in order to develop a succesufull brand strategy. These two very important dimensions of any strategy of brand are accompanying every strategical option. Creating and launching new brands depend on the strategic process of the new product development. The new brands aim at acquiring strategic advantages which are associated with the enlargement of the competence field of the company and the differentiation over existing brands. In its turn, the extension of the brand is a strategic alternative which aims at the transfer or the relaunching of the existing brands. The companies which are following the geocentric strategy need global brands. Only the companies which succesfully overcome the numerous restrictions of the global strategy development are able to get good results. Apple is a good example of a brand strategy that gained a unique position on the global market and continues to help holding it.

In their turn, thecustomers become more demanding and powerful in their relationship with service providers. They askfor more and new relationship. The appropriate new marketing, known as Relationship Marketing, looksto engage the customer interactively in the many steps of creating value which is later shared betweenservice provider and customer. This requires to focus on long-term customer relationship. In order toestablish and maintain long-term relationship, the relationship marketing should understand customerexpectations, know the customers, evaluate services process, obtain a proper service quality and adequatelymanage customers’ relationships. The service customer’s is placed on an expectation range to afive dimension scale and have two levels which may be analyzed into a model of service. A stimulus forrelationship marketing performance may be the quality of service. The objective and subjective quality ofservice is essential for the service customer relationship management. In order to reach the goal ofretaining actual customers, service companies should be prepared to spot customers who leave and thenanalyze and act on information they provide. Managers should make sure the entire organization understandthe importance of keeping customers and encourage employees to pursue zero defections by tryingincentives, planning, and budgeting to defections targets. Most important, managers use defections as avehicle for continuously improving the quality and value of the service they provide to customer.

The results of these decisions are to be found in the strategies of the brand. These strategies play a prominent part in the performant management of the brand and the strategical outcome of the company in the international markets. The succesfull, consistent international brands confirm this remarcable role of the management.
The Organic Products in the Green Marketing Laboratory
Victor Danciu
Theoretical and Applied Economics , 2008,
Abstract: A healthy way of life requires green products which protect the environment and the quality of life. Organic products have relevant green characteristics and particular benefits for the consumers, the producers and the environment. The benefits support the rapidly growing world market of organic food in both developed and developing countries. Green issues and products have a growing importance in Romania. Even if the Romanians have not become fans of the green products yet, a growing number of consumers prefer organic food. More important, Romanian organic food has success on the export markets. Supporting and promoting organic products on both domestic and international markets requires significant efforts, including those in the green marketing area. The requirements of the green marketing imply new thinking and acting towards new responsibilities and solutions. The task of the marketing is to bring on the market the green problems under the form of new products, the change of the existing products through ecological improvement and abandoning the ecologically obsolete products.
The Impact of the Culture on the International Negociations: An Analysis Based on Contextual Comparaisons
Theoretical and Applied Economics , 2010,
Abstract: The negotiation could be considered as critical part of the success within the international affaires. The participants’ culture is one of the most powerful and influential factors that could give a stimulus or an obstacle to the negotiation process and outcome. The cultural differences prevalent in the international negotiations influence the most verbal and nonverbal language within negotiation. The culture distance has as a result the appearance of task and non-task related interactions. The cultural differences and similarities between the participants are shaping the negotiation styles too.We are suggesting a single structure of the negotiation styles, which is capable of differentiating behavior of the negotiations, and benchmarks that could support the stimulation and efficiency of the negotiation process as a whole.
The Gravity Law of Marketing - a Major Reason for Change to a Better Performance
Theoretical and Applied Economics , 2010,
Abstract: Companies develop marketing strategies only for success. But, sooner or later, even the most successful strategies begin to wear out and lose their impact on the performances of the company. The mutual attraction between the marketing strategy and the performance of the company is known as the law of marketing gravity. Once a marketing strategy loses impact on the marketing performance as a result of the law of marketing gravity a fundamental change is needed. This change must be made according to a new marketing thinking during a cyclic process for development of the new marketing strategy. This paper is aiming to point out that companies must recognize the limited viability of their marketing strategies, identify the causes of the strategic wear out and implications of the law of the marketing gravity. All these should be a solid ground for marketing strategic change which must be included in the general plans of change of the company and implemented with the particular tools of the strategic management of change.
