Euclid completed his geometrical proofs in the Elements (c. 300BC) with the abbreviation “QED” (quod erat demonstrandum). This phrase was not only used in mathematics in the early modern period, but also in deductive proofs in physics, astronomy, philosophy, and ethics. This chapter is a cognitive- historical interpretation of the axiomatic-deductive ideal that consists of some widely accepted pro

As digital cameras become cheaper and better, computers more powerful, and robots more abundant the merging of these three techniques also becomes more common and capable. The combination of these techniques is often inspired by the human visual system and often strives to give machines the same capabilities that humans already have, such as object identification, navigation, limb coordination, an

We developed a mobile system for collecting and communicating heart rate data in real-time using low cost, commonly available equipment. This system could be used to monitor patients with cardiac arrhythmia over long periods of time, hopefully increasing the chance of capturing and recording an actual fibrillation, which rarely is the case today. Such recordings are useful for physicians to find t

Timely loss-of-contact detection between devices in pervasive systems using mobile networks is an important aspect for both functionality and user experience. Traditional schemes where time-to-live is defined by the service provider are not adequate in mobile networks where communication failures are frequent. On the other hand, schemes using keep-alive messaging tend to increase the communication

Despite developments in economic growth theory, the importance of savings and investment has remained consistent. It intrinsically connects to the importance of functioning financial intermediation and high levels of financial inclusion. While Sub-Saharan Africa still lags, Tanzania has during the last decade seen a rapid rise in mobile money services. This paper attempts to answer the potential o

When controlling a wheeled mobile robot with four independently steerable driving wheels, the control of the wheel coordination must be handled. Both the direction and velocity of the wheels must be coordinated to allow for proper operation of the robot. The focus of this work is on the coordination of the wheel directions. Such coordination is mostly done by solving constraint equations of the sy

In many applications involving mobile devices it is essential to track their position. Moreover, it is usually desired, to perform this localization in a distributed fashion without using a central processing unit. In this case, only distance measurements to reference nodes which are in range can be utilized. It is proposed in this thesis to also use distance measurements to other moving objects,

Purpose – The rapid proliferation of mobile context aware applications has resulted in an increased research interest towards developing specialized context data management strategies for mobile entities. The purpose of this paper is to aim to develop a new way to model mobile entities and manage their contexts accordingly. Design/methodology/approach – This paper proposes the concept of “Mobile

The preliminary remote laser-induced breakdown spectroscopy measurement of metals is performed on a mobile lidar system. The Nd:YAG laser synchronized with an ICCD spectrometer, the detection range can be achieved up to 45 m.

Background: For elderly people living in nursing homes, a transport to hospital for a radiological examination can lead to increased anxiety, disorientation and other problems related to the new environment. Objective: To investigate the usefulness of a mobile radiography service for radiological assessment of patients in nursing homes from the patient and staff perspectives. Methods: Lightweight

While machines are getting better at simulating human behavior it has become more common with the use of avatars and conversational text in mobile applications. These are used in order to induce a reflectively positive experience for the user, possibly making the user choose that application in favor of another. The balance between developing a too playful application and an uninteresting one is h

Social Mobile Apps: A Case Study of Carlsberg’s CrowdIt Purpose/Originality/Value: Through an analysis of the Carlsberg’s CrowdIt-App, the case study whishes to draw attention to three conceptual areas, which have received scant attention,namely social mobile application (app), culture, and strategic mobile campaigning. While some prominent Public Relations and Communication Management scholars ha
