The second part of the presentation (getting connecting while at sea), which I gave to the Island Cruising Association in Auckland on 12th October 2012.
The document discusses various options for getting internet access while at sea, including easy, efficient, and luxury options as well as satellite phones and Sailmail. It describes how farther distances can be seen over the horizon from taller vessels and structures. Skipr is introduced as a service that works with many devices to provide internet access via web, smartphones, satellite phones, and more, with an optional paid Plus subscription that provides additional benefits.
The Olympia is a mobile asset tracking device from Oysta Technology that uses GPS and GSM networks to track vehicles, boats, and other assets. It transmits location data to Oysta's proprietary monitoring service via GPRS or SMS. Key features include geo-fencing, speed alerts, ignition monitoring, and a web interface for viewing trip reports and managing multiple assets. The Olympia is a small, lightweight device intended to provide security and visibility for fleet managers and individual asset owners.

This document analyzes data and trends from office holiday bowling parties. It finds that bowling significantly increases smiling and moonwalking compared to other activities. Studies show the optimal party balances good food and drinks with fun bowling games. Nearly all workers surveyed preferred a bowling party to other options. As the night goes on, ties are often repurposed as headbands. Playing 4-5 bowling games allows relationships to strengthen between managers and staff, sometimes leading to secret handshakes and opportunities. The document encourages booking an event at AMF, which offers impressive facilities, food, planning and a guaranteed fun experience.
This document summarizes DeviceTester software for automatically testing NTCIP devices. It allows creating scripts to test devices, exporting test results, and supports standards like SNMP. DeviceTester provides an easy-to-use interface for debugging applications and verifying device specifications.
Vegetable oil cars can run on unprocessed vegetable oil from waste cooking oil collected from restaurants. Conversion kits allow vehicles to start on diesel then switch to vegetable oil, which must be heated to lower its viscosity. While switching fuels requires extra steps, the vegetable oil is often free from restaurants and can save owners over $50 per tank compared to diesel. However, conversion kits range from $750 to $2000 to install.
The document discusses several technologies the author learned about while constructing a media project, including Blogger for publishing work online, Slideshare for uploading PowerPoint and Word files, and iMovie for editing videos and adding sound/footage. The author found Blogger and Slideshare easy to use but encountered difficulties with sound editing in iMovie, learning about its challenges and YouTube's popularity for hosting videos.

1. A phase III trial found that ofatumumab plus chemotherapy did not significantly improve progression-free survival compared to rituximab plus chemotherapy for treating relapsed or refractory diffuse large B-cell lymphoma.
2. There were no differences in adverse events between the treatment arms.
3. Based on these results, the companies are unlikely to pursue regulatory approval for ofatumumab in this indication since it did not show a benefit over the standard rituximab treatment.

This document provides an update to a previous study on the performance of passive and active collar strategies applied to the Powershares QQQ ETF (QQQ). The update extends the analysis period through September 2010. It finds that during market declines like the tech bubble and credit crisis, collar strategies provided downside protection and strong returns compared to a long position in QQQ. However, collars underperformed during strong market climbs. The document also analyzes applying collar strategies to a small cap mutual fund and finds similar beneficial results. It concludes that active collars, which dynamically adjust based on momentum, volatility, and macroeconomic signals, tended to outperform passive collars both in-sample and out-of-sample.

Take a ride through a subway's wireless network designiBwave
Most subway routes in core urban areas are located deep underground, where macro cellular coverage is non-existent. In big cities worldwide, hundreds of thousands of commuters depend on the subway (or Métro, MTR, MRT, U-bahn, Underground, etc.) on a daily basis. They need dedicated wireless networks to stay connected. First responders also need reliable public safety networks in subways stations and tunnels. Subway systems are one of the most challenging environments for wireless network design.
The document provides an overview of the evolution of mobile technology from 1G to 4G. It discusses the key differences between 3G and 4G such as data transfer rates and bandwidth. 4G provides ultra-broadband internet access at speeds up to 100 Mbps for high mobility using technologies like LTE. It allows for applications like video conferencing and location-based services through an IP-based mobile system with wider bandwidths and a digital, hybrid network architecture. In conclusion, 4G can be described as providing mobile multimedia access anytime, anywhere with global mobility support through an integrated, customized personal network.
The LT-3100 is a maritime satellite communications system from Lars Thrane A/S consisting of a control unit, antenna unit, handset and cradle.
