TL;DR: This paper surveys various indoor positioning systems to explore the related challenges that exist in this area and evaluate some proposed solutions.
Abstract: Positioning objects has been an important topic since it is needed to locate people, guide them to a certain place, and assist companies and organizations with their assets management. Several systems and algorithms were proposed to solve the positioning problem and to enhance existing systems. In this paper, we survey various indoor positioning systems to explore the related challenges that exist in this area and evaluate some proposed solutions. We provide a categorization and classification of the current indoor positioning systems and identify some possible areas of enhancements

TL;DR: The paper presents a case study the goal of which is to investigate the possibility of determining the semantic orientation of Arabic Egyptian tweets and comments given limited Arabic resources and an Egyptian dialect sentiment lexicon.
Abstract: With the rapid increase in the volume of Arabic opinionated posts on different microblogging mediums comes an increasing demand for Arabic sentiment analysis tools. Yet, research in the area of Arabic sentiment analysis is progressing at a very slow pace compared to that being carried out in English and other languages. This paper highlights the major problems and open research issues that face sentiment analysis of Arabic social media. The paper also presents a case study the goal of which is to investigate the possibility of determining the semantic orientation of Arabic Egyptian tweets and comments given limited Arabic resources. One of the outcomes of the presented study, is an Egyptian dialect sentiment lexicon.

TL;DR: This paper draws on the extant literature on e-government policy formulation, implementation and execution to advance understanding of the factors leading to success and failure and to elaborate on the underlying enabling and inhibiting conditions.
Abstract: This paper draws on the extant literature on e-government policy formulation, implementation and execution The purpose of the synthesis of this literature is to advance our understanding of the factors leading to success and failure and to elaborate on the underlying enabling and inhibiting conditions This exercise is significant with respect to research and practice to avoid the pitfalls of imposing universal approaches to research and policy practices Rather, it will draw a distinction between generic (general) and specific (context-contingent) factors With this fundamental understanding, we can suggest the kind of factors that have strategic importance and which are irrelevant in terms of e-government policy formulations The paper, further, provides a model for successful e-government implementation

TL;DR: A current state of art literature in digital audio steganographic techniques is presented and their potentials and limitations to ensure secure communication are explored.
Abstract: Steganography has been proposed as a new alternative technique to enforce data security. Lately, novel and versatile audio steganographic methods have been proposed. A perfect audio Steganographic technique aim at embedding data in an imperceptible, robust and secure way and then extracting it by authorized people. Hence, up to date the main challenge in digital audio steganography is to obtain robust high capacity steganographic systems. Leaning towards designing a system that ensures high capacity or robustness and security of embedded data has led to great diversity in the existing steganographic techniques. In this paper, we present a current state of art literature in digital audio steganographic techniques. We explore their potentials and limitations to ensure secure communication. A comparison and an evaluation for the reviewed techniques is also presented in this paper.

TL;DR: An overview of the major localization techniques for WSNs is presented and the factors that need to be considered when selecting a localization technique are concentrated on.
Abstract: Localization of sensor nodes is an important aspect in Wireless Sensor Networks (WSNs). This paper presents an overview of the major localization techniques for WSNs. These techniques are classified into centralized and distributed depending on where the computational effort is carried out. The paper concentrates on the factors that need to be considered when selecting a localization technique. The advantages and limitation of various techniques are also discussed. Finally, future research directions and challenges are highlighted.
