Object oriented business architecture on online-exam and assignment system

So far we've covered a lot of the basics of making an iPhone application using MonoTouch, including how the MVC pattern fits in, but what about iPad applications? It turns out, building iPad applications is almost exactly like building iPhone applications, and, in fact, you can even extend your iPhone applications to run on both the iPhone and the iPad, and vice-versa.KeywordsDevice TypeTarget DeviceCurrent DeviceProject OptionUniversal ApplicationThese keywords were added by machine and not by the authors.

You do not have to have a lot of experience developing iPhone applications before you begin to realize that you may need to fetch data from a server on the Internet or that you have a CPU intensive calculation that freezes your application and prevents your user from interacting with the user interface of your application. On any platform with any computer language, the standard way of dealing with such issues is to perform these tasks in the background allowing your application’s user interface to remain responsive to a user’s interaction with your application. Fortunately, iPhone OS, like its much bigger sibling Mac OS X, provides a rich array of concurrency solutions for developers needing to use them. However, as you will see the concurrency solutions vary quite a bit in terms of their degree of complexity, level of abstraction, and scalability. This chapter is a brief survey of the concurrency solutions available and you will develop solutions with some of them. There is a definite point of view that I’ve developed by working with the iPhone SDK and trying to divine the path that Apple might take in the future that hopefully will come across. After all, whether the application is for an iPod Touch, iPhone, or an iPad it isn’t cool if the application is sluggish!

I've covered a lot of ground. You've seen how to extract metadata from sources such as your database, morph this metadata to describe business objects in an Object Relational Mapping process, build business objects, manage details such as project files, merge Windows-specific User Interface (UI) information into your metadata, and create a Windows UI. Creating WebForms leverages all of these techniques, with a few new twists. I'll focus on the twists, and not repeat previous techniques you've already seen, which means Chapter 9 will still contain useful information, even if you don't plan to do smart client development.KeywordsUser ControlBusiness ObjectVisual StudioUniform Resource LocatorXPath ExpressionThese keywords were added by machine and not by the authors.

Mobile applications are an essential element in pervasive and ubiquitous computing, and they face many challenges during their generation process from the analysis of user needs to the design of specific mobile interfaces and their development in several technological platforms. Moreover, the rise of Ambient Intelligent and context-aware environments also introduces multiple interaction aspects to be considered when using mobile devices in this kind of scenarios. The present work seeks to examine the role of design patterns and ontology models in order to help with the generation of mobile applications, which can be adapted at runtime to the various user needs, different context scenarios, interactive design modes, or technology requirements. In this way, an ontology-based framework is introduced to represent, design, and support the adaptation of user interfaces in mobile applications by using design patterns according to these user needs or preferences and the context around them. This framework provides developers with a client-server architecture that enables the access to an expert knowledge base of user, context, and pattern information together with a set of inference rules, which allow the dynamic selection of interface design patterns and the runtime adaptation of the user interface features. These ontology models and inference rules are key components of the proposed framework, and their implementation has helped to produce an example of mobile application supporting user interface adaptation processes for disabled people, which can be required in Ambient Intelligent environments. Three examples of user scenarios have been considered to assess the framework potential, and usability dimensions have been tested by a limited set of users through the produced mobile application, making the usefulness of generated adaptive user interfaces apparent.

An alternative solution for Indosport, considering the increasingly advanced smartphone development and also followed by the rapid growth of its users in Indonesia. The purpose of this study project is to produce a product in the form of a user interface (UI) and user experience (UX) design in helping to realize targeted mobile applications and not forgetting to apply the principles of visual communication design namely unity and variety, hierarchy, contrast, proportion and balance. The UI and UX design methods go through several stages of work in sequence: pre-production process, production process, and post-production. This design results in UI and UX designs that are equipped with user flow, interface designs, illustrations and prototypes. The main page of the Indosport mobile application is News, Activity, Calendar, and Profile which later on these pages there are several features that are different from the previous page. The making of this UI uses several visual languages such as medium close up, full shot, long shot, close up and medium long shot in the image section contained in the article as well as the depiction of field styles used to almost all visual UI elements. Using several principles in design, namely time to learn, speed of performance, rate of errors by users, retention over time, and subjective satisfaction. The resulting design forms will be distributed directly to the Research and Development division and the IT division from Indosport to be made a native.

In software development for people with Autistic Spectrum Disorder (ASD), it is necessary to consider specific design aspects that enable the use of web and mobile applications by such users. However, only a small part of current websites and applications is adequately designed considering the needs of these users. In this paper, we extracted quality user interface attributes regarding autistic users from guidelines found in human computer interaction literature. Based on these attributes, and through the analysis of real applications specifically designed for autistic users found in Brazil, we created new design patterns presenting practitioners with problems, solutions and examples in order to support the development of more appropriate user interfaces for ASD users. We evaluated these patterns from the point of view of practitioners involved in caring for autistic people and software engineers working in projects for autistic end-users. The results provide indicators of the usefulness and understandability of the proposed patterns, while allowing to identify improvement opportunities in their description. By providing a new set of user interface design patterns, we aim to contribute to the development of more accessible mobile and web applications for users with ASD.

There is a lot of routine work in any organization, including in recruitment agencies. Effective management organization and automation of activities of employees of recruiting agencies is not an easy task. The system should automate the routine actions of workers of recruiting agencies and be convenient for their clients. This paper proposes an approach to automating the selection of necessary medical staff. Not all information systems used by recruiting agencies can compare candidates and generate results that include several of the best candidates. Based on the analysis of the subject area, groups of parameters that significantly affect the choice of medical personnel were determined. The proposed approach is to analyze the request from the client, and then in the system find requests of other clients similar to it in terms of parameters, for which a candidate has already been found. The next step is to take the profiles of healthcare professionals that have been suggested for these requests (they act as benchmarks) to further compare them with existing candidates. Each employee profile parameter has its own similarity function. Available candidates will receive scores and will be ranked. We also additionally adjust the assessment by comparing candidates with the current request. Software was developed to automate the selection of medical personnel. For its implementation, a three-level client-server architecture is proposed. MVC (Model View Controller) architecture was chosen for the server part. The Single Page Application architectural template is used for the client part. The server part is divided into three layers, which further demarcate and structure the responsibilities of the system components. .NET technologies are used to implement business logic. SQL Server is used for the server and database provider. The use of the software implementation of the developed system demonstrated quite good results. The average time for selecting the 10 best candidates out of 500 is 0.4 seconds, and the processing of only 1 resume by a person takes several minutes.

Up to this point you have built a set of self-aware business objects and the forms needed to display the values returned by those business objects. You will now move on to developing the mechanisms that you will use to build the user interface. You can do many things to give the user a good experience with your application. In this chapter you will concentrate on building not only a functional user interface but one that looks good. This includes incorporating icons, displaying the application’s status on a status bar, and providing basic Windows functionality that users often take for granted. More than anything your goal should be to create an application that users enjoy using.

Understanding the Design of Mobile Social Networking

A recent trend in Internet of Things (IoT) is to connect billions of ordinary objects to the Internet and allows these objects to exchange data for smarter services. As smartphones have widely spread in the world and generate various data, it will represent a large portion of heterogeneous interconnected IoT devices. This trend influence users to perceive that the usability of the smartphone mobile application represents the usability of the general IoT service. This article introduces a novel IoT middleware framework to improve the usability of a mobile application, and thereby improve the usability of the IoT service provided through the mobile application. The core idea of our self-adaptive IoT middleware framework is to monitor and analyze application user's behavior, identify symptoms reducing application usability, and autonomously improve the application's interface for users without any intervention from the application developer. The effectiveness of the proposed framework is shown through case studies comparing several different mobile applications from a same business domain.

Process state synchronization-based application execution management for mobile edge/cloud computing

This study proposes a system using RFID and XBee technology to address and eliminate the problems resulting from human errors in put-away operations. The human errors in such operations are a serious problem that leads to a number of difficulties in production lines and supply-chain. The use of automated verification system in put-away operations in warehouses is rather rare. Therefore, the study draws from Information Technologies. Three modules - warehouse, racks, and forklifts - have been designed to ensure automated verification of error-free placement of goods. Also, a user interface is developed in Visual Studio C#.Net and SQL server is used for database management system. The developed system also provides monitoring of all steps of operation and enables real-time checking and supervision. Thus, it offers a reliable and transparent operation system, significantly contributes to effective management of supply chain and helps to improve high quality of fast and correct product delivery by minimizing the human errors. Thus, the study highlights the importance of automated verification system for an effective management of supply chain practices by establishing coordination among rack, forklift, warehouse modules, operator and product.

The Enhancing Quality of Prescribing Practices for Older Veterans Discharged From the Emergency Department (EQUIPPED) Potentially Inappropriate Medication Dashboard: A Suitable Alternative to the In-person Academic Detailing and Standardized Feedback Reports of Traditional EQUIPPED?

Aim: Incorporating mobile applications into traditional clinical teaching methods to assess the impact of game-based mobile applications on the practical knowledge and skill levels of venous blood specimen collection among nursing students. Background: Although game-based mobile applications are recognized as teaching aids that replicate clinical practice in a safe environment, their impact and effectiveness are relatively unknown in the education of nursing students. Design: In September 2021, a single-blind randomized controlled trial was conducted in a university-affiliated hospital in China. Methods: One hundred five nursing students were randomly divided into the control group (n = 53) and the experimental group (n = 52). All participants received the same theoretical and operational training. For the next 7 days, the experimental group used a game-based mobile application, and the control group practiced venous blood specimen collection using traditional teaching methods. We observed the before-and-after comparison of the skill performance and learning curve of both groups of participants. Results: The final skill performance scores of the nursing students in the experimental group were higher than that of the nursing students in the control group (P < 0.001). Analysis of the learning curve showed that to master the skills, the experimental and control groups needed an average of 8 and 10 repetitions, respectively. Conclusion: This mobile application has a positive learning effect on nursing students' venous blood specimen collection skills in the short term. It should be applied to the training of clinical nursing skills.
