1. Why have Personal Navigation Devices become popular? What technologies are required to facilitate the success of PNDs?

A PND uses a GPS signals to determine the device’s location and display it on a digital map. Additional software brings features such as routing, driving conditions, suggested directions, ETA, interactivity, etc.

The main features of PNDs that made them popular were convenience and accuracy of information. Before PNDs, to navigate one would need paper maps. Paper maps can become quickly outdated and cannot show current location. Users would have to know their locations in order to manually calculate a route to destination. A PND calculates the current location by triangulation of GPS signals and software calculates a route based on multiple criteria (fastest or shortest route, traffic conditions, etc).

As the technology evolved, more features were packed in PND such as POI (points of interest). While a paper map can aid in manually generate a route to known destination, it cannot help finding a POI of which location is unknown to the user.

2. Who are some of the leaders in PNDs? What are the likely factors that will contribute to winning in this marketplace?

If we are talking about dedicated PND, the market leaders are Garmin, TomTom and Magellan. However, if we are looking at the total number of GPS enabled devices that provide navigation features, then the combined sales of Samsung, Motorola, HTC and Nokia devices make the others’ position on the market just an insignificant detail.

When Google announced that turn-by-turn navigation will be available for the free Google Maps, TomTom shares lost 20% of their value and Garmin’s 16% (Wortham Jenna, 2009) showing that consumers were awaiting for the convergence of smartphone features with those provided by a PND.

I think it is very unlikely that there will be a market for dedicated PND. GPS is already a given in almost any smartphone regardless of manufacturer or carrier. Personal navigation will also become a baseline feature. I have yet to find a competitor to Google Maps that is worth the switch but eventually GPS/Maps/Navigation will be used as a framework for further differentiation such as location based augmented reality.

3. What will be a likely future for PNDs?

Their certain (not likely) future is that they will just disappear from the market as they will not be able to compete with convergent devices such as smartphones or in-car navigation systems that provide more features to the user than a dedicated PND can. Google NAV is better than any dedicated PND out there due to the fact that it is free, accurate, and always up to date and can provide additional information based on collective intelligence (traffic patterns). It is very possible that dedicated PNDs will always have a better GPS sensor due to larger form factor and dedicated purpose but the cost of the inconvenience of carrying two devices around (a smartphone and a PND) will not warrant purchasing a PND. Users will continue to get GPS capability by purchasing a must-have device, smartphone, and as the navigation software and GPS accuracy on those smartphones improve, PNDs manufacturers will have less and less arguments for convincing consumers to get yet another device.

It is possible that dedicated PND will remain relevant for some time in certain niche markets such as navigation for trucking (avoiding certain routes such downtowns and roads closed to truck traffic is not yet a feature in most if any smartphone navigation software), off-road, backpacking. However, since these are just features provided by software and not hardware it is just a matter of time until we see them on smartphones making PNDs even less relevant.

4. Apply as many TCOs to Personal Navigation Devices as possible.


Once for strictly military use, PNDs technology spilled over consumer market. These devices became more and more ubiquitous in the consumer market as their prices decreased, more features were added and became easier to use.


PND manufacturers developed core competencies in GPS engineering that allowed them to provide products and solutions for different markets. While Garmin may never see the PND market too profitable due to competition form GPS enabled smartphones, they will remain a market leader in GPS devices for aviation and marine use.

Assistant Professor of Medicine chemotherapy in metastatic colon cancer Jonas A de Souza1,2*, Blase Polite1,2,3, Monica Perkins4, Neal J Meropol5, Mark J Ratain1,2,6, Lee N Newcomer4 and G Caleb Alexander7 Abstract Background: Newer systemic therapies have the potential to decrease morbidity and mortality from metastatic colorectal cancer, yet such therapies are costly and have side effects. Little is known about their non-evidence-based use. Methods: We conducted a retrospective cohort study using commercial insurance claims from UnitedHealthcare, and identified incident cases of metastatic colon cancer (mCC) from July 2007 through April 2010. We evaluated the use of three regimens with recommendations against their use in the National Comprehensive Cancer Center Network Guidelines, a commonly used standard of care: 1) bevacizumab beyond progression; 2) single agent capecitabine as a salvage therapy after failure on a fluoropyridimidine-containing regimen; 3) panitumumab or cetuximab after progression on a prior epidermal growth factor receptor antibody. We performed sensitivity analyses of key assumptions regarding cohort selection. Costs from a payer perspective were estimated using the average sales price for the entire duration and based on the number of claims. Results: A total of 7642 patients with incident colon cancer were identified, of which 1041 (14%) had mCC. Of those, 139 (13%) potentially received at least one of the three unsupported off-label (UOL) therapies; capecitabine was......

Applications presented include real time DSL access line monitoring and IPTV monitoring, correlated with lightning reports. The solution is used in the field of proactive monitoring, enabling the operator's helpdesk and field technical teams to pinpoint the cause of service degradations. Keywords— network monitoring; IoT; DSL; IPTV, lightning; visualisation; correlation I. INTRODUCTION Today, telecommunications operators offering access (i.e. xDSL, FTTx) and services (i.e. IPTV, Internet access, VoIP) are confronted with the problem of SLA (Service Level Agreement) and minimization of operational cost. In xDSL (including FTTN and local loop shortening), the fulfillment of SLA is an issue due to crosstalk, which is the interference between two pairs of a cable. Increasing the number of subscribers on the same cable, shortening the last mile, increasing the speeds, the mixture of different broadband technologies and interference with wireless devices causes degradation of service already on physical......

Siemens Ag: Global Development

...For the exclusive use of N. Sinden, 2015. 9-602-061 REV: MARCH 18, 2002 STEFAN THOMKE Siemens AG: Global Development Strategy (A) It was the spring of 2000, but even under the afternoon shade of the palm trees at the Oberoi hotel in Bangalore, South India, it felt like summer. Horst Eberl sat contemplating the recommendations that he and his subdivisional co-head, Karl-Friedrich Hunke, would be preparing for the Siemens Information and Communications Networks (ICN) management board. Things were neat, tidy, and cool on this grassy side of the hotel. Just outside the main walls however lay the dust, pollution, and confusion of the Indian traffic. And if one took life in one’s hands by darting through the traffic, across the street lay Siemens’ regional development center in India, scattered among floors rented in three different office buildings. Two back-up power generators, as well as battery backup for all computers, helped ensure a reliable infrastructure for the 600 personnel here. What vexed Eberl and Hunke was that Deutsche Telekom, Siemens ICN’s largest customer, was upset because of slow product delivery on a new telecommunications software product, the so-called NetManager. For a variety of reasons the project had rapidly mushroomed in size and scope beyond what had been initially envisioned. To solve the problem, Eberl, co-head of ICN’s largest subdivision, had to travel some 7000 kilometers to this dusty corner of the world: despite the......

Internet addiction has been considered as a serious threat to mental health and the excessive use of the Internet has been linked to a variety of negative psychosocial consequences. The aim of this review is to identify all empirical studies to date that used neuroimaging techniques to shed light upon the emerging mental health problem of Internet and gaming addiction from a neuroscientific perspective. Neuroimaging studies offer an advantage over traditional survey and behavioral research because with this method, it is possible to distinguish particular brain areas that are involved in the development and maintenance of addiction. A systematic literature search was conducted, identifying 18 studies. These......

Twitter Mood Predicts the Stock Market

...content of daily Twitter feeds by two mood tracking tools, namely OpinionFinder that measures positive vs. negative mood and Google-Profile of Mood States (GPOMS) that measures mood in terms of 6 dimensions (Calm, Alert, Sure, Vital, Kind, and Happy). We cross-validate the resulting mood time series by comparing their ability to detect the public’s response to the presidential election and Thanksgiving day in 2008. A Granger causality analysis and a Self-Organizing Fuzzy Neural Network are then used to investigate the hypothesis that public mood states, as measured by the OpinionFinder and GPOMS mood time series, are predictive of changes in DJIA closing values. Our results indicate that the accuracy of DJIA predictions can be significantly improved by the inclusion of specific public mood dimensions but not others. We find an accuracy of 87.6% in predicting the daily up and down changes in the closing values of the DJIA and a reduction of the Mean Average Percentage Error by more than 6%.

Iit for the Sytem of the System

...11 December 2015 Abstract The recent economic crisis has brought considerable changes also to food consumption: on one hand, many products have recorded consistent absolute declines in demand, while on the other hand, we have witnessed preferences shift towards low-cost foods or, in any event, foods of lower quality standards. In order to study these phenomena and, especially, the strategies firms adopt to confront them, the wine sector constitutes a particularly interesting focus due to its wide supply range and the elevated reactivity to price and income of demand. Our paper intends to take a close look at wine consumptions, focusing on the sales made on the Mass Retail Trading (MRT) channel from 2009 to 2013, and to conduct a thorough analysis of the performances of the single products, in view of pointing out the sector's overall trend, as well as the principal typologies of wine, in terms of their sales results in that period. Applying Latent Class Regression has permitted us to identify six explicative models of performances, demonstrating the effect on sales of the structural characteristics of productions and sales strategies. & 2015 UniCeSV, University of Florence.

Benefits of 3 D Modelling

...3D modeling to help them win. However, some manufacturers are not only adopting 3D modeling technology, but excelling at hitting their product development targets at the same time. How is it possible? Interestingly enough, it’s actually quite simple. Key Business Value Findings • Best in class manufacturers their hit revenue, cost, launch date, and quality targets for 84% or more of their products. • Best in class performers typically produce 1.4 fewer prototypes than average performers. • Best in class performers average 6.1 fewer change orders than laggard performers. • In total, best in class manufacturers of the most complex products get to market 99 days earlier with $50, 637 lower product development costs. Implications & Analysis How do they do it? • Best in class performers are 40% more likely to have engineers use CAD directly to ensure they stay close to the design. • Best in class performers are 24% more likely to take advantage of extended 3D modeling design capabilities. They are 55% more likely to use downstream capabilities. • All (100%) best in class performers acquired new hardware when adding 3D modeling, compared to 53% of laggards. Recommendations for Action • Initially document design deliverables in electronic form. • Allow engineers to use 3D modeling tools rather than allocating them to drafters. • Deploy the advanced design and downstream capabilities of...

On-Chip Networks from a Networking Perspective: Congestion and Scalability in Many-Core Interconnects

...On-Chip Networks from a Networking Perspective: Congestion and Scalability in Many-Core Interconnects George Nychis†, Chris Fallin†, Thomas Moscibroda§, Onur Mutlu†, Srinivasan Seshan† † Carnegie Mellon University {gnychis,cfallin,onur,srini} § Microsoft Research Asia ABSTRACT In this paper, we present network-on-chip (NoC) design and contrast it to traditional network design, highlighting similarities and differences between the two. As an initial case study, we examine network congestion in bufferless NoCs. We show that congestion manifests itself differently in a NoC than in traditional networks. Network congestion reduces system throughput in congested workloads for smaller NoCs (16 and 64 nodes), and limits the scalability of larger bufferless NoCs (256 to 4096 nodes) even when traffic has locality (e.g., when an application’s required data is mapped nearby to its core in the network). We propose a new source throttlingbased congestion control mechanism with application-level awareness that reduces network congestion to improve system performance. Our mechanism improves system performance by up to 28% (15% on average in congested workloads) in smaller NoCs, achieves linear throughput scaling in NoCs up to 4096 cores (attaining similar performance scalability to a NoC with large buffers), and reduces power consumption by up to 20%. Thus, we show an effective application of a network-level concept, congestion control, to a class...
