The rapid growth in mobile technology makes the delivery of healthcare data and services on mobile phones a reality. However, the healthcare data is very sensitive and has to be protected against unauthorized access. While most of the development work on security of mobile healthcare today focuses on the data encryption and secure authentication in remote servers, protection of data on the mobi...

The utilization of spin waves as eigenmodes of the magnetization dynamics for information processing and communication has been widely explored recently due to its high operational speed with low power consumption and possible applications for quantum computations. Previous proposals of spin wave Mach-Zehnder devices were based on the spin wave phase, a delicate entity which can be easily disru...

guidance, support and encouragement. His expertise and vision in experimental and theoretical research has taught me a great deal, not only to handle a problem in the right direction, but also bring productive results with fast pace. Iowa fabrication and characterization equipment.

We present a general method to quantify both bipartite and multipartite entanglement in a device-independent manner, meaning that we put a lower bound on the amount of entanglement present in a system based on the observed data only but independent of any quantum description of the employed devices. Some of the bounds we obtain, such as for the Clauser-Horne-Shimony-Holt Bell inequality or the ...

Organic nanowires (ONWs) are flexible, stretchable, and have good electrical properties, and therefore have great potential for use in next-generation textile and wearable electronics. Analysis of trends in ONWs supports their great potential for various stretchable and flexible electronic applications such as flexible displays and flexible photovoltaics. Numerous methods can be used to prepare...

Mobile devices generally have small screens. To display information that is well suited for larger screens (e.g. desktop computers), the information has to be segmented into many small presentation units that can fit into the small screen of mobile devices. This makes it difficult to effectively organize information and help users navigate to and from the information they want. This paper prese...

The traditional method in Iran of cracking walnut manually, using harmer or knife cutter is laborintensive, slow and tedious; besides, most mechanical crackers do not give satisfactory results in terms of kernel extraction quality. A prototype machine was developed to crack walnut. A walnut cracker was designed, constructed and tested to evaluate its performance. The cracker, which consists of ...

At first step polymer optical fibers (POFs) are used in short distance for optical data transmissions. At second step SiO2 nanoparticles were prepared by sonochemical-assisted method. Silica nanoparticles were added to polymer matrix to prepare polymer based nanocomposites. Most of the POF applications are in the medical and electrical devices. There are several methods for fabrication of POFs,...

A growing number of connected devices and solutions, related to the concept of Internet of Things, makes our environment increasingly smart and capable. However, existing application development processes and tools, designed for single device applications, do not allow to fully address this opportunity and to efficiently create applications that employ multiple devices and use the context infor...

Morpho-syntactic patterns device encompasses a subcategory of the cohesive devices that assists hearers to have an adequate mental representation for understanding speech. This article investigates the morpho-syntactic patterns employed in some Persian live sport radio and TV programs adapting Dooley and Levinsohn’s theoretical and analytical framework. The research data includes around 30,000 ...
