However, the challenges posed by having a large number of users such as power control, frequency synchronization and independently faded channels scales with the number of users. Cooperative communications is a candidate technology for high data rate and multi-user communications. In this paper, a new design of distributed network codes is introduced. These network codes are based on algebraic constructions in finite fields. Finite fields have an attractive feature of constraining transmit signal energy and is resilient to fading channels. The codes have high diversity and scale up with an arbitrary number of users. The codes are an alternative to Generalized Dynamic Network Codes without a restriction on the field size. Results are compared to theoretical evaluations and systems with similar configurations.","PeriodicalId":265963,"journal":{"name":"Int. J. Handheld Comput.

This method can be utilized for generating arbitrary prescribed probability density functions pdf. A cybersecurity engineering problem associated with Internet traffic is addressed. The synthetic Levy-walks process is intertwined with sections of distinct characteristics creating a composite signal that is analyzed through zero-crossing rate ZCR within a varying-size window to identify sections. The advantages of the ZCR computation directly in the time-domain are appealing for real-time implementations. Moreover, the characterization of the degree of closeness, via the Kullback-Leibler divergence KLD, among the pdfs of arbitrary processes focusing on Levy walks and model pdfs is presented. The results obtained from the KLD experiments provide a categorical determination of the closeness degree. These results, a remarkable achievement in this research, are also promising to be used as features for classification of complex signals in real-time.","PeriodicalId":265963,"journal":{"name":"Int.

The majority of these systems cannot detect the size and location of the damage. Guided wave techniques are widely used to detect damage in structures due to its sensitivity to different changes in the structure. Finding a mathematical model for such system will help to implement a reliable and efficient low-cost SHM system. In this paper, a mathematical model is proposed to detect the size and location of damages in physical structures using the piezoelectric sensor. The proposed model combines both pitch-catch and pulse-echo techniques and has been verified throughout simulations using ABAQUS/ Explicit finite element software. For empirical verification, data was collected from an experimental set-up using an Aluminum sheets. Since the experimental data contains a lot of noises, a Butterworth filter was used to clean up the signal. The proposed mathematical model along with the Butterworth filter have been validated throughout real test bed.","PeriodicalId":265963,"journal":{"name":"Int. J. Handheld Comput.

Using four higher learning institutions located in Dar es Salaam as case study, data were collected, digitized and analyzed. Results showed that despite having access to computers and other forms of information technologies, most decision makers rely on tradition methods such word of mouth, document review and meetings to arrive to most of their decisions.

The system relies on the use of a smartwatch to deliver an alert via vibration and text display whenever a wrong activity that violated the proper body mechanics has been detected. A core contribution of this study is a registration mechanism for a healthcare professional to explicitly give permission to the system to monitor his or her activities. Furthermore, a non-intrusive biometrics-based single sign-on mechanism is incorporated into the system to allow a user to be automatically identified for tracking as long as the user has manually registered with the system before.

Since the appearance of the iPhone -and also later of the iPad-, terminal vendors had lost traction as triggers of innovation within the mobile content ecosystem, giving way to the current platform-based paradigm of leadership. This paper proposes examining the innovation potential of wearable devices on the whole mobile set of actors, starting from a two-scenarios premise: one of sustaining innovation, and a second scenario of more prominent influence. The research finds significant innovating potential for the smart kind of wearables, with a range of influence that can modify the course of all current mobile players. Also, it points at the possibility that a strong development of these items can eventually give birth to a new kind of media, specifically conceived for the wearable experience.","PeriodicalId":265963,"journal":{"name":"Int.

Data from mobile internet adoption and use will be discussed in the light of the above mentioned theoretical approaches. Two complementary views are approached -mobile internet stakeholders' and users'-encouraging a discussion on the interdependencies between individual adoption patterns and market derived determinants in a socio-cultural environment where technology adoption and diffusion happens. Results will provide contributions for the understanding of this type of technology adoption processes and the increasing importance of mobility in cultural and social practices, promoting an exciting discussion on the centrality of media nowadays and the current transformation processes society is undergoing.","PeriodicalId":265963,"journal":{"name":"Int.
