The Emergency Managers Weather Information Network (EMWIN) is a system that disseminates weather data and alerts via satellite, radio, and internet. It provides rapid distribution of forecasts, graphics, imagery and other weather products. EMWIN collects data from various sources, prioritizes and packages it, then transmits the data stream to satellites and stations for rebroadcast to users including emergency managers, TV stations, pilots, and the public.

Achieving capacities above 1 gbps ed02
This document summarizes the capabilities of SAFTehnika's wireless backhaul solutions for achieving over 1Gbps capacities. It discusses available licensed spectrum bands with channel bandwidths up to 2000MHz that can support data rates over 8Gbps per radio. Mounting multiple radios to a single antenna is described as a way to save 5-10dB in link budget. A case study of a 1.7Gbps dual polarization link over 40 miles of water is provided. Layer 1-3 aggregation techniques are outlined including built-in and external options. Future E-band radios are projected to use 128QAM or higher with automatic coding and modulation capabilities.

BridgeX_SURVEY_solutions
The RTK Bridge-X is a mobile device that receives real-time kinematic (RTK) corrections over a cellular network and rebroadcasts them to rovers via radio. This allows surveyors to access corrections in areas with limited cellular coverage. The Bridge-X provides reliable corrections with less interference than traditional methods. It offers flexibility to work from vehicles and minimize setup time. The device can also host corrections from a local base station and share them over the internet or broadcast via radio when cellular is unavailable.

HLA-A*26 was also significantly associated, while HLA-E*01:01 was not observed to have any significant association. Analysis of linkage disequilibrium structures between the Japanese and Han Chinese cohorts found differences in the HLA-A and HLA-E regions that could explain differences in susceptibility between
Healthy Christians Make Healthy Churches - Church Re-Imagined
The document discusses how healthy Christians and churches approach suffering, sickness, and sin. It suggests that healthy Christians 1) pray to God and praise Him in all things, 2) repent of sins and confess to one another, and 3) pray for one another's healing. When the church practices confession and mutual prayer, it experiences healing. The example of Elijah is given, who was an ordinary man but highly effective in prayer because of his righteousness and obedience to God. Healthy Christians concentrate on obedience and bringing glory to God.
The fight of the dart nose airplane2
The student conducted an experiment to test how alterations to a paper airplane's design affected its flight. The airplane was launched six times with different combinations of a paper clip added to the nose and the elevator flaps positioned up or down. Observations showed the airplane with a paper clip on the nose traveled farthest, while one with just lowered flaps went the shortest distance. The student concluded the paper clip helped drag the airplane farther after landing, while lowered flaps kept one airplane aloft longer without other changes to assist its travel distance.

2013 04 future of interchange
The document discusses the future of interchange fees in the United States ATM industry. It notes that independent ATM deployers have seen declining transaction revenues over the last 10 years due to market saturation and competition. Fluctuating interchange fees set by card networks have not benefited independent deployers. Now, industry leaders are pushing for changes to allow more competition and consumer choice by permitting differential surcharging to offset lower interchange fees. The lawsuits against Visa and MasterCard argue their "no differential surcharge" rules create unfair business practices for independent deployers. Overall the declining and unstable interchange fees coupled with rising compliance costs threaten the sustainability of independent ATM operators in the US.

The Smokefree Class Competition (SFC) is a universal school-based smoking prevention program for students aged 11-14. The program aims to delay or prevent smoking initiation and encourage smoking cessation. It involves classes signing contracts promising to be smokefree for 6 months. Students self-monitor smoking and classes can win prizes for abstaining. Evaluations show SFC reduces smoking rates by 6 percentage points. Over 30,000 classes and 700,000 students have participated across 22 European countries. Studies found no evidence SFC causes bullying and may reduce isolation. SFC is considered an effective program ready for wide dissemination.

Simplex ES Net Launch Technical Presentation.pptx
The document provides information about Johnson Controls' Simplex ES Net Fire Alarm Network release 1.2, which features several enhancements:
1) Support for multiple loops on the TrueSite Workstation, allowing connection of up to 7 ES Net loops or a mix of ES Net and 4120 loops. This expands network capacity.
2) Support for multiple topologies beyond the traditional ring structure, including star, ring, bridged rings, and rings with spurs to provide more flexible system design.
3) Ability to carry both fire and supplemental traffic over the ES Net infrastructure, with the traffic separated to ensure fire alarm data transmission. The supplemental channel provides extra bandwidth for applications like remote client connections or video.

Vsat
VSATs, or Very Small Aperture Terminals, are small satellite terminals used to transmit data, video, or voice via satellite with no additional staff. They consist of an outdoor transceiver to communicate with a satellite and an indoor device like a PC. A hub station controls the network by routing signals between VSAT terminals through satellites in a star topology. VSAT networks provide reliable remote communications for customers like retailers, hotels, and oil rigs at a lower overall cost than leased telephone lines.

EVS WaterSpy
WaterSpy is a system that uses wireless devices to monitor water usage and detect leaks. It collects hourly water meter readings and sends the data to an online database through concentrator devices. The online interface called Nemo allows users to view water usage statistics and set alarms. The system helps utilities and customers improve water efficiency and identify issues. It can also be expanded to monitor other resources using additional sensor modules.

Smart grid and wide area monitoring
This document outlines a tutorial on smart grid frequency monitoring that will be presented at the IEEE International Conference on Smart Energy Grid Engineering in Canada in August 2013. The tutorial will cover the topics of wide area monitoring systems, the Egyptian wide area monitoring system (EWAMS), the architecture of EWAMS, and its applications. EWAMS was implemented through a research project that installed 10 frequency disturbance recorders in power stations across Egypt to monitor the electric grid in real-time.
Vsat
The document summarizes VSAT technology, including its definition, history, components, uses, and future applications. Key points include:
- VSAT stands for Very Small Aperture Terminal and uses small satellite dishes less than 3.8 meters to transmit and receive data via satellite.
- The technology has been in development since the 1920s and was first used commercially in the 1960s for satellite television broadcasts.
- Modern VSAT systems use components like antennas, BUCs, LNBs, and indoor modems to transmit and receive data via geosynchronous satellites.
- Applications include broadband internet access, VoIP, and monitoring systems. The maritime VSAT market was over $400 million in 2007.

under water wireless communication
Underwater acoustic communication is a technique of sending and receiving message below water.[1] There are several ways of employing such communication but the most common is using hydrophones. Under water communication is difficult due to factors like multi-path propagation, time variations of the channel, small available bandwidth and strong signal attenuation, especially over long ranges. In underwater communication there are low data rates compared to terrestrial communication, since underwater communication uses acoustic waves instead of electromagnetic waves.
