Evaluation and Improvement of Web Application Quality A Case Study
Web applications, especially those commonly used by a vast number of clients, should fulfill high quality standards. In this paper, we discuss evaluation and improvement of quality attributes on the example of web applications that support city cards for public transport in urban areas. Their quality has been assessed with a set of autonomous evaluation tools in terms of usability, findability in Internet (SEO) accessibility, design, content, mobile, and performance. Quality of the applications has been compared to quality of a new prototype developed as a Single Page Application (SPA) An improved prototype has been created that referred to suggestions offered by the tools. The case study has also presented effects of the prototype improvement on its quality attributes, and relevance of the tool usage.

Regeneration Rosetta: An interactive web application to explore regeneration associated gene expression and chromatin accessibility
Time course high throughput assays of gene expression and enhancer usage in zebrafish provide a valuable characterization of the dynamic mechanisms governing gene regulatory programs during CNS axon regeneration. To facilitate the exploration and functional interpretation of a set of fully processed data on regeneration associated temporal transcription networks, we have created an interactive web application called Regeneration Rosetta. Using either built in or user provided lists of genes in one of dozens of supported organisms, our web application facilitates the (1) visualization of clustered temporal expression trends; (2) identification of proximal and distal regions of accessible chromatin to expedite downstream motif analysis; and (3) description of enriched functional gene ontology categories. By enabling a straightforward interrogation of these rich data without extensive bioinformatic expertise, Regeneration Rosetta is broadly useful for both a deep investigation of time dependent regulation during regeneration in zebrafish and hypothesis generation in other organisms.

Application of accessibility guidelines in a virtual museum.
This work consisted in applying a web accessibility model in accordance with the WCAG 2.1 guidelines for the development of a virtual museum, as well as studying the context of museum accessibility, the perspectives of the groups involved in its development, the time, effort and investment required, and providing an answer on who are the people that require accessibility.The software development team performed two types of tests on the web application: An automated test and manual test. In the case of automated tests, the tools used automatically perform a quick review of the website and evaluate aspects such as color contrast, text size, consistency in the HTML structure, styles and page navigability, while for manual tests, solutions based on WCAG 2.1 were implemented to comply with the principles: i) Perceptible, automatic text reading, and zoom function were added to see an image in detail; ii) Operable: keyboard navigation was added to all the website's functionalities, iii) Understandable: symbols were designed in a consistent way to the action they represent, and all images have an adequate description, iv) Robust, the website allows the user to use their own technologies, adapting to them. Finally, tests were conducted with disabled users using a questionnaire and focus group techniques to assess their perception on using the website and the results indicate the website is accessible.

Early Accessibility Evaluation in Web Application Development
Existing accessibility guidelines are mainly focused on runtime behavior and do not provide recommendations and evaluation for conceptual design of Web applications. Our approach aims to support more abstract principles for analysis and design of accessible Web applications. Combined with a prototype evaluation, it provides early integration of accessibility requirements into the process of Web application development. The approach is based on a model driven user interface design method. Analysis of tasks and workflow is used to design a prototype which is evaluated with a simple screening technique to get fast and efficient results on selected accessibility requirements. The longtime objective of this work is a general concept for software development which bridges the gap between user requirements and developers needs in the field of accessibility.

Spatial Accessibility to Hospitals Based on Web Mapping API: An Empirical Study in Kaifeng, China
The accessibility of hospital facilities is of great importance not only for maintaining social stability, but also for protecting the basic human right to health care. Traditional accessibility research often lacks consideration of the dynamic changes in transport costs and does not reflect the actual travel time of urban residents, which is critical to time sensitive hospital services. To avoid these defects, this study considered the city of Kaifeng, China, as an empirical case, and directly acquired travel time data for two travel modes to the hospital in different time periods through web mapping API (Application Program Interface) Further, based on travel time calculations, we compared five baseline indicators. For the last indicator, we used the optimal weighted accessibility model to measure hospital accessibility for each residential area. The study discovered significant differences in the frequency and spatial distribution of hospital accessibility using public transit and self driving modes of transportation. In addition, there is an imbalance between accessibility travel times in the study area and the number of arrivals at hospitals. In particular, different modes of transportation and different travel periods also have a certain impact on accessibility of medical treatment. The research results shed new light on the accessibility of urban public facilities and provide a scientific basis with which local governments can optimize the spatial structure of hospital resources.

Developing secure Web applications Security criteria for the development of e Democracy Web applications
One of the most important requirements in government websites is the security. The Data Protection Act, Human Rights Act and other legislation require that privacy is respected. Beyond this, Government websites must be secure to build trust and maintain the reputation of electronic government. This will be seriously damaged if websites are defaced, services are unavailable or sensitive information is released to the wrong people. Securing a Web application is difficult, not only because of various technical departments coordination involved, but also because most security tools are not designed to address the Web application as a whole, including how the different pieces of the application interact with each other. The potential for a security breech exists in each layer of a Web application. Traditional security solutions, such as access control or intrusion detection/prevention systems, are specialized to protect different layers of the Internet infrastructure, and are usually not designed to handle HTTP and HTML attacks. While these tools are useful for their specific functions, they do not address all of the issues that Web applications present. More important, using these tools can give administrators a false sense of confidence if they do not know that the other vulnerabilities exist. This paper is being performed in the context of the e Voto project, a Portuguese project dealing with the complexity of the electronic voting systems, in particular to the dissemination of electoral results over the WWW. So, in this paper the authors present some recommendations to web applications development that manage and present important information like electoral results with medium high security level.

HUEQUITAS: Web Application for Location of Low Cost Restaurants
Over the years Internet accessibility has increased in a remarkable way and now, besides this, the use of devices such as smartphones, tablets and laptops allows people to access a large variety of applications, among which are those that enable users to locate places such as restaurants, hotels and parks, allowing quick access to that information. This document presents the development and implementation of a web application for the geolocation of low cost restaurants, commonly called "huequitas" Our application uses HTML5, CSS, PHP and JavaScript for the development of the web page and implements the Google Maps API to improve the search experience for locating all the "huequitas" in the sector. The application locates the current position of the user; and, based on the users position, shows the nearby "huequitas" along with the route to follow in order to reach each place. This application is characterized for using MySQL, an Open Source database and three layer architecture at the network level. The design of the application is specifically for a web platform, but being responsive it can be viewed from a smartphone or tablet.

Flexible Automatic Support for Web Accessibility Validation
Automatic support for web accessibility validation needs to evolve for several reasons. The increasingly recognised importance of accessibility implies that various stakeholders, with different expertise, look at it from different viewpoints and have different requirements regarding the types of outputs they expect. The technologies used to support Web application access are evolving along with the associated accessibility guidelines. We present a novel tool that aims to provide flexible and open support for addressing such issues. We describe the design of its main features, including support for recent guidelines and tailored results presentations, and report on first technical and empirical validations that have provided positive feedback.
