Green Driving Application : Eco DrivingAhmadi, Lina January 2016 (has links)
Eco-driving has acquired great importance in recent years because it is a way to reduce energy consumption that can be applied to any type of vehicle. However, for these rules to be applied requires a process of continuous learning and motivation. For this reason many eco-driving assistants have emerged. This paper presents Green Driving, a driver safety app for Android that detects inattentive driving behaviors and gives corresponding feedback to drivers, scoring their driving and alerting them in case their behaviors are unsafe. It’s about changing a person’s driving behavior by providing some kind of advice to the driver. I have worked on an algorithm that is meant to reduce the fuel consumption of users. The algorithm is deployed in an android application. This application “Green Driving” is aimed at users with cars. It is basically like an assistant, suggesting the user when he should make the right gear changes, when to increase/decrease speed and avoids hard braking and rapid acceleration and etc. It is in order to drive economically, ecologic and in turn save money and safety. This is a smart way of letting a user drive economically and ecologic since almost everyone has an Android smartphone now.

Comparing Native and Hybrid Applications with focus on FeaturesMohammadi Kho'i, Felix, Jahid, Jawed January 2016 (has links)
Nowadays smartphones and smartphone-applications are a part of our daily life. There are variety of different operating systems in the market that are unalike, which are an obstacle to developers when it comes to developing a single application for different operating system. Furthermore, hybrid application development has become a potential substitute. The evolution of new hybrid approach has made companies consider hybrid approach as a viable alternative when producing mobile applications. This research paper aims to compare native and hybrid application development on a feature level to provide scientific evidence for researchers and companies choosing application development approach as well as providing vital information about both native and hybrid applications.This study is based on both a literature study and an empirical study. The sources used are Summon@BTH, Google Scholar and IEEE Xplore. To select relevant articles, the Snowballing approach was used, with Inclusion and Exclusion criteria’s.The authors concluded that native development is a better way to develop more advanced applications which uses more device-hardware, while hybrid is a perfectly viable choice when developing content-centric applications.

Android application of Doctor’s end in E-health systemChen, Lingzhen January 2013 (has links)
In recent years, with the arrival of information era and the rapid development of the medical health system, there has been a trend for hospitals and medical care centers to record the patients’ medical record electronically rather than by means of old-fashioned paper-based method. It has indeed reduced the workload of medical workers and it simplifies the procedure within the medical system. It is worth mentioning that the growth of mobile medical care is beginning to catch up as a consequence of the incredible popularization of mobile networks and the broad use of mobile devices. A significant possibility is that in the coming years, mobile medical care applications will play a large part of the whole electronic medical care system. This project will mainly focus on presenting the process of developing an Android application of doctor’s end in the electronic healthcare system which makes it possible for doctors to retrieve data from their patients and diagnose them as well as setting up appointments using mobile devices. The development for the doctor’s end application will follow the waterfall development methodology. In this report the functions of the doctor’s end application will be introduced, and how these functions are realized will also be displayed in detail. After the implementation, the app will be tested on an Android device emulator and on real Android mobile devices in order to evaluate their performance. In addition, it will be tested by mobile phone specialists in relation to gathering feedback. Finally, a reasonable conclusion will be drawn with regards to this project including ethical issues.

Hur forensiska verktyg påverkar integriteten på mobiltelefonerAronsson, John, Bolmér, Percy January 2016 (has links)
Användandet av mobiltelefoner och andra mobila enheter är stort i samhället vilket gör att de förekommer allt oftare vid brott och brottsutredningar. Information i dessa enheter måste kunna utvinnas och integriteten på det utvinna materialet säkerställas. Syftet med detta arbete är att undersöker om de forensiska verktygen Xry och Encase påverkar materialet vid utvinning från mobiltelefoner. För att ta reda på detta har en litteraturstudie, en intervju och två experiment utförts. Resultatet från experimenten visade på att det fanns filer vars innehåll ändrades mellan utvinningar. En analys av resultatet visade att det var systemet själv samt processer som skedde innan utvinningen som förändrat innehållet. Slutsatsen blev att verktygen inte påverkar materialet under utvinningsprocessen / The rising use of smartphones and other mobile devices in society today has resulted in a higher prevalence of these in crimes and crime investigations. The information in these devices must be extracted and the integrity of the extracted information assured. The goal of this project is to determine whether the two forensic software programs Xry and Encase tamper with the extracted data. To answer this, a literary study together with an interview and two experiments were performed. The result from the experiments determined that data changes occured between extractions. Further analysis explained the changes to be caused by the devices themselves, and as a consequence of rooting. The conclusion drawn from the result was that the softwares programs did not tamper with the material during the extraction-process.

Rent a home: a cross platform mobile application to list and search rental homesAli, Yusuf January 1900 (has links)
Master of Science / Department of Computing and Information Sciences / Daniel Andresen / Finding a desired off-campus home could be a difficult task for incoming students at K-State. This cross platform mobile application can help students in this task. This mobile application will serve as platform for students and home owners to find, list and review a property. Users can create their personal account and manage their profile and properties they listed. They can post multiple property listings with the key details and these listings will be visible to all the other users.
To avoid spam and repetitive postings there is an address verification system in place. While posting a property listing the address is verified with Google maps database. If Google maps fail to identify the address or if that address is already listed, the user will not be allowed to list that property.
Users can see all the property listings and their details including a Google map location image, a link to navigate to the address, contact details of the owner, reviews of other users. Users can rate a property from 1(low) to 5(high) along with an optional review. The review and rating can help other user to select a desired place to live.
The user interface is developed with web technologies and using Cordova the same code can be used to convert it into a mobile application for both iOS and Android which makes this application platform independent and easily available.
