Dynamic Mobile Anonymity with Mixing
Staying anonymous and not revealing real identity is highly desired in today's mobile business. Especially generic frameworks for different kinds of context-aware mobile business applications should provide communication anonymity of mobile users as a core security feature. For enabling communication anonymity, Mix-net based solutions are widely accepted and used. But directly deploying existing Mix-net clients on mobile devices with limited hardware capacity is not a realistic approach. In addition, different anonymity sensitivities of both applications and users require to enforce anonymity dynamically rather than on a fixed level. In this paper, we present an approach towards a solution that addresses the specific anonymity challenges in mobile business while exploiting the benefits of existing Mix-net frameworks
Reactor Neutrino Experiments with a Large Liquid Scintillator Detector
We discuss several new ideas for reactor neutrino oscillation experiments
with a Large Liquid Scintillator Detector. We consider two different scenarios
for a measurement of the small mixing angle with a mobile
source: a nuclear-powered ship, such as a submarine or an
icebreaker, and a land-based scenario with a mobile reactor. The former setup
can achieve a sensitivity to at the 90%
confidence level, while the latter performs only slightly better than Double
Chooz. Furthermore, we study the precision that can be achieved for the solar
parameters, and , with a mobile reactor
and with a conventional power station. With the mobile reactor, a precision
slightly better than from current global fit data is possible, while with a
power reactor, the accuracy can be reduced to less than 1%. Such a precision is
crucial for testing theoretical models, e.g. quark-lepton complementarity.Comment: 18 pages, 3 figures, 2 tables, revised version, to appear in JHEP,

Quantifying mixing using magnetic resonance imaging.
Mixing is a unit operation that combines two or more components into a homogeneous mixture. This work involves mixing two viscous liquid streams using an in-line static mixer. The mixer is a split-and-recombine design that employs shear and extensional flow to increase the interfacial contact between the components. A prototype split-and-recombine (SAR) mixer was constructed by aligning a series of thin laser-cut Poly (methyl methacrylate) (PMMA) plates held in place in a PVC pipe. Mixing in this device is illustrated in the photograph in Fig. 1. Red dye was added to a portion of the test fluid and used as the minor component being mixed into the major (undyed) component. At the inlet of the mixer, the injected layer of tracer fluid is split into two layers as it flows through the mixing section. On each subsequent mixing section, the number of horizontal layers is duplicated. Ultimately, the single stream of dye is uniformly dispersed throughout the cross section of the device. Using a non-Newtonian test fluid of 0.2% Carbopol and a doped tracer fluid of similar composition, mixing in the unit is visualized using magnetic resonance imaging (MRI). MRI is a very powerful experimental probe of molecular chemical and physical environment as well as sample structure on the length scales from microns to centimeters. This sensitivity has resulted in broad application of these techniques to characterize physical, chemical and/or biological properties of materials ranging from humans to foods to porous media (1, 2). The equipment and conditions used here are suitable for imaging liquids containing substantial amounts of NMR mobile (1)H such as ordinary water and organic liquids including oils. Traditionally MRI has utilized super conducting magnets which are not suitable for industrial environments and not portable within a laboratory (Fig. 2). Recent advances in magnet technology have permitted the construction of large volume industrially compatible magnets suitable for imaging process flows. Here, MRI provides spatially resolved component concentrations at different axial locations during the mixing process. This work documents real-time mixing of highly viscous fluids via distributive mixing with an application to personal care products
Influence of preparation method on the performance of vanadia-niobia catalysts for the oxidative dehydrogenation of propane
The influence of various preparation methods on the performance of V-Nb-0 catalysts has been investigated. It was found that the activity and selectivity of a vanadium site depend on the nature of the neighbouring atoms. Vanadium neighbours provide activity, while niobium neighbours provide selectivity. Careful preparation of these catalysts ensures a homogeneous distribution and good mixing of the vanadium and niobium. It was also found that the vanadium becomes mobile upon reduction and this results in better distribution of vanadium in used catalysts
Dynamic-Epistemic reasoning on distributed systems
We propose a new logic designed for modelling and reasoning about information flow and information exchange between spatially located (but potentially mobile), interconnected agents witnessing a distributed computation. This is a major problem in the field of distributed systems, covering many different issues, with potential applications from Computer Science and Economy to Chemistry and Systems Biology. Underpinning on the dual algebraical-coalgebraical characteristics of process calculi, we design a decidable and completely axiomatizad logic that combines the processalgebraical/ equational and the modal/coequational features and is developed for process-algebraical semantics. The construction is done by mixing operators from dynamic and epistemic logics with operators from spatial logics for distributed and mobile systems. This is the preliminary version of a paper that will appear in Proceedings of the second Conference on Algebra and Coalgebra in Computer Science (CALCO2007), LNCS 4624, Springer, 2007.

Traffic agents for improving QoS in mixed infrastructure and ad hoc modes wireless LAN
As an important complement to infrastructured wireless networks, mobile ad hoc networks (MANET) are more flexible in providing wireless access services, but more difficult in meeting different quality of service (QoS) requirements for mobile customers. Both infrastructure and ad hoc network structures are supported in wireless local area networks (WLAN), which can offer high data-rate wireless multimedia services to the mobile stations (MSs) in a limited geographical area. For those out-of-coverage MSs, how to effectively connect them to the access point (AP) and provide QoS support is a challenging issue. By mixing the infrastructure and the ad hoc modes in WLAN, we propose in this paper a new coverage improvement scheme that can identify suitable idle MSs in good service zones as traffic agents (TAs) to relay traffic from those out-of-coverage MSs to the AP. The service coverage area of WLAN is then expanded. The QoS requirements (e.g., bandwidth) of those MSs are considered in the selection process of corresponding TAs. Mathematical analysis, verified by computer simulations, shows that the proposed TA scheme can effectively reduce blocking probability when traffic load is light
Age Optimal Information Gathering and Dissemination on Graphs
We consider the problem of timely exchange of updates between a central
station and a set of ground terminals , via a mobile agent that traverses
across the ground terminals along a mobility graph . We design the
trajectory of the mobile agent to minimize peak and average age of information
(AoI), two newly proposed metrics for measuring timeliness of information. We
consider randomized trajectories, in which the mobile agent travels from
terminal to terminal with probability . For the information
gathering problem, we show that a randomized trajectory is peak age optimal and
factor- average age optimal, where is the mixing
time of the randomized trajectory on the mobility graph . We also show that
the average age minimization problem is NP-hard. For the information
dissemination problem, we prove that the same randomized trajectory is
factor- peak and average age optimal. Moreover, we propose an
age-based trajectory, which utilizes information about current age at
terminals, and show that it is factor- average age optimal in a symmetric
setting
Organising self-referential taxi work with mICT: the case of the London black cab drivers
London Black Cab Drivers have a rich and documented history of mobile work practices that are geographically distributed and driven by situated choices for everyday work. To date mobile studies researchers have not made a close examination of these mobile working practices, hence there is a gap in mobile studies concerning this type of worker. This dissertation aims to study the evolution of Black Cab drivers' work practices since the introduction of mobile Information and Communication Technology (mICT) in their everyday work. The theoretical framework for the research is based on studies of taxi drivers' work practices, mobility research, computer supported co-operative work and organisational change promoted by IS interventions. The ontology of this research pinpoints the factors influencing the situated and idiosyncratic choice associated with the use of mICTs when carrying out planned and unplanned work. The case study references a 420-year history of "old", established work practices as a comparison framework. When compared with the "new" and situated choice of mICT-supported work, it becomes apparent that there has been a change in the dynamics of how this type of work is actually completed. Embedding and mixing elements of self-referenced work - as discretionary and independent - with working practices in which mutual interdependencies are supported by the use of mICT aids seems to provide the case for a re-negotiation of the working practices model as well as its associated organisational forms, together with a social shift in the definition of the role and skills required to perform this type of mobile work.
The empirical data have been sourced from one-to-one interviews and video recordings using a combination of ethnographic methods and interpretative approaches for the data analysis. This dissertation makes a theoretical and practical contribution to mobile studies by understanding the changing of working practices; it further offers methodological insights for studying mICT-supported work. Finally, it provides a formative evaluation of the new organisational forms emerging as mICT has been introduced to everyday Black Cab work
