Today, Web3D technologies and the rise of new standards, combined with faster browsers and better hardware integration, allow the creation of engaging and interactive web applications that target the field of cultural heritage. Functional, accessible, and expressive approaches to discovering the past starting from the present (or vice-versa) are generally a strong requirement. Cultural heritage artifacts, decorated walls, etc. can be considered as palimpsests with a stratification of different actions over time (modifications, restorations, or even reconstruction of the original artifact). The details of such an articulated cultural record can be difficult to distinguish and communicate visually, while entire archaeological sites often exhibit profound changes in terms of shape and function due to human activities over time. The web offers an incredible opportunity to present and communicate enriched 3D content using common web browsers, although it raises additional challenges. We present an interactive 4D technique called “Temporal Lensing”, which is suitable for online multi-temporal virtual environments and offers an expressive, accessible, and effective way to locally peek into the past (or into the future) by targeting interactive Web3D applications, including those leveraging recent standards, such as WebXR (immersive VR on the web). This technique extends previous approaches and presents different contributions, including (1) a volumetric, temporal, and interactive lens approach; (2) complete decoupling of the involved 3D representations from the runtime perspective; (3) a wide range applications in terms of size (from small artifacts to entire archaeological sites); (4) cross-device scalability of the interaction model (mobile devices, multi-touch screens, kiosks, and immersive VR); and (5) simplicity of use. We implemented and developed the described technique on top of an open-source framework for interactive 3D presentation of CH content on the web. We show and discuss applications and results related to three case studies, as well as integrations of the temporal lensing with different input interfaces for dynamically interacting with its parameters. We also assessed the technique within a public event where a remote web application was deployed on tablets and smartphones, without any installation required by visitors. We discuss the implications of temporal lensing, its scalability from small to large virtual contexts, and its versatility for a wide range of interactive 3D applications.

This chapter is a call to archaeologists and museum curators to reflect upon their roles in the production of knowledge surrounding antiquities and to take more responsibility for historical awareness and appreciation in Egypt. Historical objects transform in significance over time and are in constant re-creation of identity, so we must keep pace with their contemporary relevance, and we should use that relevance to start a discourse on the construction of new identities in relation to cultural memories of the past through the contemporary interpretations of these objects in the daily life of different communities. People cannot appreciate what they do not know; if Egyptians do not have access to the knowledge of their ancient past, they will not understand the value of the significance of its material remains, and will continue to allow, through neglect, the total loss of archaeological sites to looting and commercial urbanization. In the end, this loss will result in a complete attrition of cultural heritage and historical memory that will further lead to a more diluted identity.

Currently the Internet became one of the media that can not be separated, as well as a wide variety of applications supplied her. As the development of technologies, reliance on Web applications also increased. However, web applications have a wide range of threats, one of it is a CSRF (Cross-Site Request Forgery). This study uses CSRF (Cross-Site Request Forgery) Protection. CSRF (Cross-Site Request Forgery) Protection is a treatment method that has a variety of ways, one of which uses a token in the session when the user login. Token generated at login will be used as a user id that the system of web applications to identify where the request originated.  The results of this study are expected in order to increase web application defenses against CSRF (Cross-Site Request Forgery), so that web application users will be able to feel safe in using the Internet and its various feature. Reduced level of attacks on web applications. So that visitor traffic on the web application can be increased.

Nowadays security becomes more important than the content and the SEO of a web application. Due to a lack of protection, the number of attacked websites augments in the past few years. In most of the cases, developers are either uninformed or unqualified to implement security during the application development, which causes a huge amount of data flaws. Supporting the developers and easily managing the workflow, some organizations have developed different kind of guidelines for security integration. Such guide helps handling the security from the outset of the development process, which influence over the protection of the entire application. The one used in this article is a project developed by Open Web Application Security Project (OWASP) Foundation named OWASP Secure Headers Project. Its aim is to show the developers the balance between usability and security implemented through http headers. By giving general data and examples of HTTP response headers usability it is a platform which help increasing the security of the application. In this article, we explain the necessity of HTTP Security Headers and how they can help in preventing a cyber invasion in our web application! We will give details on the most important HTTP headers and will retrieve a basic information for some with a lower need. We will give examples for their implementation in one ASP.NET web application to provide more descriptive perspective of their use! In the recent years, browsers have integrated certain security header controls to support the web application security. Those headers give instructions to the browser how to behave when handling sensitive content and data of the application. If developers enable them in the application, browser will prevent attacks automatically. But not all browsers support them, which brings a compatibility question: what are the alternatives in a case of deprecated header on a specific browser. As a part of the research we will provide an analyze of the use of the HTTP headers in some of the most common sites used in Bulgaria with the help of ALEXA Top 1 Million sites. There have already been developed a lot of applications to show if a certain website has HTTP security headers implemented. Most of them are freely to use and gives detailed information on what was done and what should be done in case that specific layer of security is missing from the web application. The need of security in the web applications become more and more necessary. Along with other security implementations on a programming and on a server level the ones described in the article bring another layer of security management that mitigates certain types of cyberattacks and vulnerabilities.

It is shown that the application of the Internet technologies is relevant in the selection of crop production technologies and the formation of a rational composition of the machine-and-tractor fl eet taking into account the conditions and production resources of a particular agricultural enterprise. The work gives a short description of the web applications, namely “ExactFarming”, “Agrivi” and “AgCommand” that provide a possibility to select technologies and technical means of soil treatment, and their functions. “ExactFarming” allows to collect and store information about temperature, precipitation and weather forecast in certain areas, keep records of information about crops and make technological maps using expert templates. “Agrivi” allows to store and provide access to weather information in the fi elds with certain crops. It has algorithms to detect and make warnings about risks related to diseases and pests, as well as provides economic calculations of crop profi tability and crop planning. “AgCommand” allows to track the position of machinery and equipment in the fi elds and provides data on the weather situation in order to plan the use of agricultural machinery in the fi elds. The web applications presented hereabove do not show relation between the technologies applied and agro-climatic features of the farm location zone. They do not take into account the phytosanitary conditions in the previous years, or the relief and contour of the fi elds while drawing up technological maps or selecting the machine-and-tractor fl eet. Siberian Physical-Technical Institute of Agrarian Problems of Siberian Federal Scientifi c Center of AgroBioTechnologies of the Russian Academy of Sciences developed a software complex PIKAT for supporting machine agrotechnologies for production of spring wheat grain at an agricultural enterprise, on the basis of which there is a plan to develop a web application that will consider all the main factors limiting the yield of cultivated crops.

Anticorruption in History is the first major collection of case studies on how past societies and polities, in and beyond Europe, defined legitimate power in terms of fighting corruption and designed specific mechanisms to pursue that agenda. It is a timely book: corruption is widely seen today as a major problem, undermining trust in government, financial institutions, economic efficiency, the principle of equality before the law and human wellbeing in general. Corruption, in short, is a major hurdle on the “path to Denmark”—a feted blueprint for stable and successful statebuilding. The resonance of this view explains why efforts to promote anticorruption policies have proliferated in recent years. But while the subjects of corruption and anticorruption have captured the attention of politicians, scholars, NGOs and the global media, scant attention has been paid to the link between corruption and the change of anticorruption policies over time and place. Such a historical approach could help explain major moments of change in the past as well as reasons for the success and failure of specific anticorruption policies and their relation to a country’s image (of itself or as construed from outside) as being more or less corrupt. It is precisely this scholarly lacuna that the present volume intends to begin to fill. A wide range of historical contexts are addressed, ranging from the ancient to the modern period, with specific insights for policy makers offered throughout.

Content is a key influencing factor in Web Quality of Experience (QoE) estimation. A web user’s satisfaction can be influenced by how long it takes to render and visualize the visible parts of the web page in the browser. This is referred to as the Above-the-fold (ATF) time. SpeedIndex (SI) has been widely used to estimate perceived web page loading speed of ATF content and a proxy metric for Web QoE estimation. Web application developers have been actively introducing innovative interactive features, such as animated and multimedia content, aiming to capture the users’ attention and improve the functionality and utility of the web applications. However, the literature shows that, for the websites with animated content, the estimated ATF time using the state-of-the-art metrics may not accurately match completed ATF time as perceived by users. This study introduces a new metric, Plausibly Complete Time (PCT), that estimates ATF time for a user’s perception of websites with and without animations. PCT can be integrated with SI and web QoE models. The accuracy of the proposed metric is evaluated based on two publicly available datasets. The proposed metric holds a high positive Spearman’s correlation (rs=0.89) with the Perceived ATF reported by the users for websites with and without animated content. This study demonstrates that using PCT as a KPI in QoE estimation models can improve the robustness of QoE estimation in comparison to using the state-of-the-art ATF time metric. Furthermore, experimental result showed that the estimation of SI using PCT improves the robustness of SI for websites with animated content. The PCT estimation allows web application designers to identify where poor design has significantly increased ATF time and refactor their implementation before it impacts end-user experience.

Modelling Approach

SummaryTask modelling has entered the development process of web applications, strengthening the usage-centred view within the early steps in Web-Engineering (WE). In current approaches, however, this view is not kept up during subsequent activities to the same degree as this is the case in the field of Human-Computer-Interaction (HCI). The modelling approach presented in this contribution combines models as known from WE with models used in HCI to change this situation. Basically the WE-HCI-integration is supported by combining task and object models as known from HCI with conceptual modelling known from WE. In this paper, the main focus is on the WebTaskModel, a task model adapted to web application concerns, and its contribution towards a task-related web user interface. The main difference to existing task models is the build-time and run-time usage of a generic task lifecycle. Hereby the description of exceptions and erroneous situations during task performance (caused by, e.g., the stateless protocol or Browser interaction) is enabled and at the same time clearly separated from the flow of correct action.

As we know internet has become a very important factor in our day today life. It is a wide media for communication and exchange of ideas for people staying in any nook and corner of the world. We have proposed a system in which we are developing a speech interactive web application services. Our main aim is to provide these services to the special ones who are unable to make use of the current system so efficiently. In our proposed work we are mainly focusing on the WEB APPLICATIONS. Many a times the disabled people are unable to access internet, for them this system will help to download news, or even access their mails through speech. Our proposed system mainly deals with the ability to handle web applications along with the O.S, mouse and keyboard control through speech, so that they can be used by persons without the use of the hands to develop an interface between the computer and the user. In our proposal we have used SAPI .It provides commands to the main central application which is handled by the GUI. Thus we look forward to develop web application through speech interaction.
