Smart phones are equipped with a wide range of sensors (such as GPS, light, accelerometer, gyroscope, etc.) and allow users to be connected everywhere. These characteristics offer a rich information source for creating context-aware applications. However, testing these applications in the lab, before their deployment, could become a hard task or impossible because of sensors correlation, too wide testing area or an excessive number of people involved. This work aims to solve these problems carrying out the testing in a simulator, simulating the world in which the application user is immersed into. Tester controls her avatar and the avatar has a simulated smart phone that is connected with the user’s smart phone. Applications under test are installed on the real smart phone and are compiled with a library that replaces standard services of the sensors by others that offer data sensor from the simulator (depending on the simulated smart phone context) instead of real world.

Recently, the integration of geographical coordinates into a picture has become more and more popular. Indeed almost all smartphones and many cameras today have a built-in GPS receiver that stores the location information in the Exif header when a picture is taken. Although the automatic embedding of geotags in pictures is often ignored by smart phone users as it can lead to endless discussions about privacy implications, these geotags could be really useful for investigators in analysing criminal activity. Currently, there are many free tools as well as commercial tools available in the market that can help computer forensics investigators to cover a wide range of geographic information related to criminal scenes or activities. However, there are not specific forensic tools available to deal with the geolocation of pictures taken by smart phones or cameras. In this paper, an image scanning and mapping tool for investigators is proposed and developed. This tool scans all the files in a given directory and then displays particular photos based on optional filters (date/time/device/localisation…) on Google Map. The file scanning process is not based on the file extension but its header. This tool can also show efficiently to users if there is more than one image on the map with the same GPS coordinates, or even if there are images with no GPS coordinates taken by the same device in the same timeline. Moreover, this new tool is portable; investigators can run it on any operating system without any installation. Another useful feature is to be able to work in a read-only environment, so that forensic results will not be modified. This tool's real-world application is also presented and evaluated in this paper.

The importance of communication increases development of information and communication technology in world so rapidly, especially in telecommunications equipment. Mobile phone or smart phone is one type of communication tools that provide communication services to a wide range of features offered but the services offered are not free. Handy Talky is applications and services to communicate for free with the use of smart phones based on Android and has a wifi enable this feature. This communication utilizing wifi network at a frequency of 2.4 GHz as to communication network. Test the application is done by trying on some of the features on a smart phone application with different specifications. From the test produced a smart phone that can run the application properly in some smart phones with Android operating system version 4.2 and above, and the smartphone is connected to a wifi network


There are distinct modes for communication. Smart phones played an essential role in this era. Smart phones that can also be worked as computer and helps us to do a limited amount of work. According to statistics there are 3.3 billion smart phone users in the world. It also becomes extremely helpful for study purpose and for official purpose. They often create fewer bonds with their family. Due to surplus use of phone it made ravage in family relationship. Thus the usage of smart phone results in considerable deviation in family relationship .This paper deals with gender based smart phone addiction and effect on family relationships. The paper focuses on predictive methods like naive bayes, Knn and logistic regression to find out how the smart phones are going to create an impact in family relations. This helps to find smart phones effects in family relationship. The problems due to high consumption of it can be identified and future precautions can be taken immediately according to it.

The paper reflects the specificity of the fundamental ideas of the artistic world of M. G. Atamanov, which includes a wide range of literary facts from the content level of the text of the works to their poetics. A particularly important role in the works of M. G. Atamanov is played by cross-cutting themes and images that reflect the author's individual style and his idea of national-ethnic identity. The subject of the research is the book of essays “Mon - Udmurt. Maly mynym vös’?” (“I am Udmurt. Why does it hurt?”), which most vividly reflected the main spiritual and artistic searches of M. G. Atamanov, associated with his ideas about the Udmurt people. The main motives and plots of the works included in the book under consideration are accumulated around the concept of “Udmurtness”. The comprehension of “Udmurtness” is modeled in his essays through specific leit themes: native language, Udmurt people, national culture, mentality, geographic and topographic features of the Udmurt people’ places of residence, the Orthodox idea. The “Udmurt theme” is recognized and comprehended by the writer through the prism of national identity.

Neglected Diseases (NDs) affect million of people, especially the poorest population around the world. Several efforts to an effective treatment have proved insufficient at the moment. In this context, triazole derivatives have shown great relevance in medicinal chemistry due to a wide range of biological activities. This review aims to describe some of the most relevant and recent research focused on 1,2,3- and 1,2,4-triazolebased molecules targeting four expressive NDs: Chagas disease, Malaria, Tuberculosis and Leishmaniasis.
