Enhancing mobile advertising via Bluetooth technology

This paper presents a Multimedia Message Transmitter Tool (MMTT) that provides businesses with the opportunity to use Bluetooth wireless connectivity delivering the relevant information to relevant people in the right places and time. MMTT empowers any business to market their services or products for unlimited time with a one-time fee. It provides the ability to deliver customised content on a permission-based manner to all devices in the range of 100 m to 1 km. MMTT supports users right of privacy and ensures spam-free delivery of content to interested users. Experimental results show that MMTT provides a viable solution for realising mobile advertising for the advertisers as well as the consumers.

Models for using internet technology to support flexible e-learning

Information and Communication Technologies (ICTs) have been diffused in higher education slower than it has been expected. Especially for developing countries, using ICT in the most efficient and effective ways has crucial importance for the sustainable development and effective use of resources. This paper presents a theory-based design framework for e-learning that emphasises the transformative interaction between technology readiness and innovativeness. This study is a theory-building investigation and offers a theory-into-practice framework that characterises the implications of innovativeness and motivation in the recent trend of the higher education use of internet technology to facilitate its own operations, in the form of e-learning.

Checking the efficiency of integrity tests in distributed and parallel database

With the increased use of the applications that deal with massive collections of data, integrity checking became a critical problem. Efficient checking could be achieved by deriving a simplified form of the integrity constraints against the new database state before the update operation is performed. Most of the research projects in this area are concentrated on deriving sufficient integrity tests for distributed databases. However, no attention has been given to validating the appropriateness of these integrity tests. In this paper, we provide a complete solution for checking constraints in the distributed database system. The proposed technique is not limited to generate sufficient and complete integrity tests but it also selects the suitable test from several alternative tests. Experimental results showed how the complete tests can significantly improve the performance of the constraint checking mechanisms with respect to the amount of data transferred across the network.

Smart Solutions for Smart Cities: Using Wireless Sensor Network for Smart Dumpster Management

Wireless sensor networks are being deployed in civil, military, environmental and health applications due to their versatility, low cost and rapid communication capabilities. Smart cities would be able to manage their services with the help of information and communication technologies relying to a great extent on wireless sensor networks. In this paper, we propose the use of wireless networking technologies to optimize the solid waste management through the use of smart dumpsters equipped with waste level sensors. These sensors can read the level of waste as being low, medium or high. The HC-SR04 ultrasonic sensors, selected for this study, yield the level sense results that can be used at the municipal authority server to deploy just the sufficient number of trucks and staff for waste collection. In addition, path planning and routing can be done to minimize the time and fuel needed. We have developed a simulation model and performed simulation for optimization of fuel and time.

Achieving extended displays prototype via Wi-Fi direct technology

Wi-Fi Direct is considered as the way to connect people by offering a wider connectivity to the authorized devices. This paper presents a prototype that connects more than two displays wirelessly to create a VGA host by integrating the Miracast Application Program Interface (API) with Wi-Fi direct technology. This achievement supports high-quality multimedia streaming, audio and video conferencing, texts, gaming and more other applications. The behavior of the proposed prototype is measured by assessing the minimum number of connected group of devices, as well as the expected throughput in real life scenario. The experimental results show a remarkable overall performances measured by throughput, significance and applicability of the proposed prototype.

Integrated model of photovoltaic solar system with the sound biometric techniques

Photovoltaic system (PVS) is used for generating electric power by using solar cells to convert energy from the sun light into a flow of direct current electricity, which can be used to power equipment or to recharge a battery. In addition, the Sound biometric techniques can enable PVS to listen and understand their surrounding auditory environment since turning the lights on all the nights will get through a lot of energy which it might be used in other significant concerns. This paper proposed a model of combination between PVS to generate power energy (electricity) from the sunlight controlled by a sound biometric technique to reduce the consumption of the generated power energy by turning the lights on for the highways only when there are cars on the highway and only for some period of time to make the driving out of harmful ways and trouble-free; followed by an implementation of the proposed combination model between the PVS and biometric sound chip and a presentation of a discussion of the proposed system results.

A Novel Approach to Build a Generic Model of Photovoltaic Solar System Using Sound Biometric Techniques

This chapter presents the proposed model of combination between Photovoltaic solar system resources and sound biometric techniques, to generate power energy from the sunlight using the PVS controlled by a sound biometric technique. This work contributes to research knowledge by proposing and validating a sound biometric technique for allowing to reduce the consumption of the generated power energy by turn the lights on for the public roads only when there are vehicles on the way and only for some period of time to make the driving out of harms way and trouble-free. The proposed and combination models between the PVS and biometric sound chip is used for generating electric power by using solar cells to convert energy from the sun light into a flow of direct current electricity, which can be used to power equipment or to recharge a battery. In addition the Sound biometric techniques can enable PVS to listen and understand their surrounding auditory environment since turning the lights on all the time will get through a lot of energy which it might be used in other significant concerns.

FAST PURSUIT OF MOBILE NODES USING TPR TREES

In this paper, we consider a set of mobile nodes, each of which moves with constant velocity. We present algorithms to determine which of these mobile nodes can be captured the soonest by a set of one or more pursuers. We use a time parameterized R-tree (TPR-tree) to index these moving points. We then develop algorithms that operate on the TPR-tree to answer three query variations: (1) a single pursuer that is faster than all of the mobile nodes, (2) a single pursuer that is slower than some of the mobile nodes and (3) multiple pursuers. Experimental results show that our algorithms are simpler and faster than other approaches to solve the problem.
