One important design decision for the development of autonomously navigating mobile robots is the choice of the representation of the environment. This includes the question which type of features should be used or whether a dense representation such as occupancy grid maps is more appropriate. In this paper, we present an approach which performs SLAM using multiple representations of the enviro...

For a typical portable handheld device, the backlight accounts for a significant percentage of the total energy consumption (e.g., around 30% for a Compaq iPAQ 3650). Substantial energy savings can be achieved by dynamically adapting backlight intensity levels on such low-power portable devices. In this paper, we analyze the characteristics of video streaming services and propose an adaptive sc...

In this paper we present the development of a method that combines the evolutionary robotics approach with action selection. A collection task is set in an arena where a Khepera robot has to collect cylinders that simulate food. Furthermore, two basic motivations, labeled as ‘fear’ and ‘hunger’, both affect the selection of the behavioral repertoire. In this paper we propose an initial evolutio...

Because the cost of attracting new customers is much higher than the cost of retaining old customers, keeping customers loyal is a crucial issue for service firms. This research explores how relationship quality and switching barriers influence customer loyalty. Relationship quality consists of two aspects: satisfaction and trust. Antecedents of satisfaction and trust are explored. To test the ...

In this paper we present enhancements for a wireless PCS architecture which distributes processing from the mobile switching centers and cell sites. In a wireless environment all the call processing components need access to the subscriber data. The subscriber profile distributing scheme envisioned for this architecture provides a method to localize data in clusters and access it remotely, whic...

A MANET is a remote system in which hubs can go about as sender/collector or even as delegates prefer switches. Hubs in a MANET may act up with an aim to preserve assets. This happens due to restricted assets accessible for every hub. This causes an incredible effect on the whole system execution. In this paper we examine about MANET as zones and groups with a Static Agent as a focal hub and a ...

Ensuring seamless and reliable switching across different constituent technologies is the basic requirement of heterogeneous wireless networks. IEEE 802.21 standard is recommended for 4G networks for coordinating among different mobile network for better services. Still, there exists a scope of further improving its performance by introducing the fuzzy logic concepts in it. The present work aim...

Driven by the pervasion of privately owned mobile devices, in recent years, we witness a trend of consumers rather than enterprises increasingly diffusing technology innovations into work environments. Today, owners of ubiquitous technologies (e.g., smartphones, social networks) not only use them privately but also apply them on business purposes, which is known as Bring Your Own Device (BYOD) ...

Nowadays, many people have several mobile devices with them and frequently move in and out of small adjacent networks. They also join and leave networks frequently by simply switching their devices on and off. Configuration and reconfiguration of mobile devices are critical processes for these users, due to the different specifications. In order to provide an “easy-to-use network”, future resea...

This paper investigates the problem of finite-time state feedback stabilization for nonholonomic mobile robot with stochastic disturbance in the forward velocity. First of all, an appropriate state/input transformation is introduced to convert the mentioned control model into stochastic nonholonomic system in chain form. Then, by using stochastic finite-time stability theorem and the method of ...
