Mule provides a transformer that converts XML data into objects by using annotation decorated model classes, requiring the name of the component, fully qualified name of the root class, colon separated package name of model classes, and MIME type. The transformer allows a simple flow to transform XML data into objects using annotated model classes.
Implementacija, evaluacija, dizajn multimedijske prezentacije, struktura stranice, navigacija, elementi za navigaciju, strukturiranje teksta i dodavanje multimedijskih elemenata.
The document presents a new method called BIM 2D-LDA (Fusion of Bidirectional Image Matrices and 2D-LDA) for face recognition. It rearranges face images into horizontal and vertical matrices to capture discriminative information in both directions. It then applies 2D-LDA to the matrices to extract features. The method is tested on two face databases and achieves higher recognition accuracy than other methods like 2D-PCA, (2D)2PCA, (2D)2LDA, and (2D)2PCALDA, while also having lower running times.

This document outlines three principles for building commercial influence: 1) Attention pays - gaining attention through compelling content is important for influence, 2) Follow the water - focus on where audiences spend their time both online and through apps, and 3) Collaborate - partnering with other influential organizations can help spread ideas to larger audiences totaling over 100 million people globally. The document provides examples of how The Guardian newspaper has successfully built influence through trustworthy news coverage and unstoppable stories that engage audiences across different platforms.
Social media has become the dominant way for people to access news content. Both fast, short form content and longer, in-depth articles are important, with consumers preferring headlines that help them decide what to read fully. Collaboration between publishers and sharing high-quality content is key to reaching large audiences. Video, especially on mobile devices, is increasingly popular but brands must consider how to create valuable experiences beyond short advertisements. Personalization raises concerns about echo chambers and loss of serendipity, so a human touch is important. Evolving business models include membership, paywalls, and partnerships to fund valuable journalism and connect brands with audiences in live experiences.
This document discusses creating a model for measuring online engagement to help advertisers maximize ad effectiveness. It summarizes research that:
1) Identified key engagement factors like attitudes, behaviors, and interactions through a literature review and user survey.
2) Linked these engagement factors to ad recall and effectiveness metrics through a large survey combining user responses, web analytics and ad impact.
3) Developed a single "engagement score" combining the most influential factors to engagement. Higher scores correlated with increased ad recall and purchase consideration.
4) Proposes an engagement planning tool to help advertisers target audiences based on engagement profiles rather than just reach, providing a greater likelihood of reaching responsive individuals.

The document discusses influential brands and influence measurement. It finds that brand influence is made up of four pillars: commercial, societal, audience, and outward influence. The top drivers of influence in the UK are found to be positive, inspirational, trustworthy, having unique and interesting things to say. The top ten most influential UK brands are listed, with the #1 brand having an influence score of 58.3. Data from surveys in three markets show that more influential brands also tend to have greater customer loyalty. The document concludes with three rules for brands to be influential: understand the different influence pillars, demonstrate being positive, trustworthy and inspirational, and understand key influence drivers in their category.
This document discusses the importance of trust in business and how media brands can build trust through paid, owned, and earned channels. It notes that trust is the most important currency in a networked world. The Guardian is highlighted as the most trusted media brand in the UK. The document advocates building trust by staying true to brand values across paid advertising placements, owned content on platforms like mobile, and earned engagement on social media.
