The mobile traffic has grown rapidly with the popularity of smart mobile devices. To accommodate increasing traffic, heterogeneous network integration is considered as a viable solution. By overlapping the coverage of heterogeneous networks (e.g., the long-term evolution (LTE) and Wi-Fi integrated network), the mobile operators can use the offloading service (e.g., Wi-Fi offloading) to reduce n...

Long Term Evolution (LTE) is expanding its utilization in unlicensed band by deploying LTE Unlicensed (LTEU) and Licensed Assisted Access LTE (LTE-LAA) technology. Smart Grid can take the advantages of unlicensed bands for achieving two-way communication between smart meters and utility data centers by using LTE-U/LTE-LAA. However, both schemes must co-exist with the incumbent Wi-Fi system. In ...

This paper introduces the first wireless gesture recognition system that operates using existingWi-Fi signals and devices. To achieve this, we first identify limitations of existing wireless gesture recognition approaches that limit their applicability to Wi-Fi. We then introduce algorithms that can classify gestures using information that is readily available on Wi-Fi devices. We demonstrate t...

In contrast to B-DNA that has a right-handed double helical structure with Watson–Crick base pairing under the ordinary physiological conditions, repetitive DNA sequences under certain conditions have the potential to fold into non-B DNA structures such as hairpin, triplex, cruciform, left-handed Z-form, tetraplex, A-motif, etc. Since the non-B DNA-forming sequences induce the genetic instabili...

In the current study, micro-scale mobility is analyzed in connection to visitors’ experiences. Methods are examined in two different surroundings to test their eligibility: GPS devices and questionnaires are tested in combination with interviews and overview camera. Empirical results show that visitors are fairly mobile, and that experience hotspots exist in time and space. It is concluded that...

This paper examines the broadband connectivity options available in digital cities. It offers an overview of services provided by commercial operators, the public sector and by citizens themselves, arguing that shortcomings in existing fixed broadband and commercial mobile broadband services provide an opportunity for citizens to share their own wireless broadband connections. It explores Wi-Fi...

Human computing promises new capabilities that cannot be easily provided by computing machinery. However, humans are less disciplined than their mechanical counterparts and hence are liable to produce accidental or deliberate mistakes. As we start to develop regimes for identifying and correcting errors in human computation, we find an important model in the computing groups that operated at th...

The goal of exploration through telerobotics is to broaden our understanding of the universe. Towards this goal, the EventScope project at Carnegie Mellon University merges educational software and a telescience / telerobotics mission interface for use within classroom settings to provide more direct connections to new information. Answering scientific questions requires mission interaction on ...

Wireless networks are commonly used by people. Market devices are equipped with the new security standard 802.11i. The standard announced in the middle of 2004 is commonly used to protect WLANs. Currently we can find the information that vulnerabilities were found in that standard. Then a question arises: Are WLANs compromised again? The article describes vulnerabilities which were discovered i...

This paper provides a review of data on the improves. War seems beneficial to the environment only if it keeps people out of large areas. It could be useful to eCects of the civil war on forest areas in the Democratic Republic of Congo. Only a few of these eCects were extend the concept of peace parks to war zones. The idea of an international ‘green force’ to protect biodiversity beneficial, t...
