Malleus (zip)

Malleus changes the amplitude of your sound. You then guess what amount of attenuation was applied in dB over a range of 1 to 50 dB. Malleus can be used on an individual track or the main mix outputs. This version is the first release on CNET Download.com.

Modeling Signal Attenuation in IEEE 802.11 Wireless LANs - Vol. 1

Path loss models are used to approximate signal attenuation as a function of the distance between transmitters and receivers, being an important building block for both research and industry efforts. This paper presents experimental data that validates the use of the log-distance model both inside and outside a standard office...

Canon Vixia HG20

The Canon Vixia HG20 is an excellent HD camcorder that's reasonably easy to operate out of the box and looks good, too. It's almost identical to the company's Vixia HF11, but rather than recording mainly to internal flash memory, it records to a hard drive. As for performance, it's as...

Canon Vixia HF11

Creating a product line where once there was but one, Canon follows up its flash-based, high-definition Vixia HF10 AVCHD camcorder with a slightly more powerful model, the HF11. Like its sibling, the HF11 is a sleek black compact model with a well-rounded feature set, great video, and excellent performance, and...

Structured Errors in Optical Gigabit Ethernet Packets

This paper presents a study of the errors observed when an optical Gigabit Ethernet link is subject to attenuation. The paper uses a set of purpose-built tools which allows to examine the errors observed on a per-octet basis. The paper finds that some octets suffer from far higher probability of...

Multi-Uplink Passive Optical Networks

Passive Optical Network PON is one of the important access network technologies to provide end users the cost effective broadband services. The coverage of a PON is mainly restricted by the optical signal loss between the Optical Line Terminal OLT and the K Optical Network Units ONUs. Even if the...

Location Independent Compact Routing for Wireless Networks

While reactive routing protocols such as AODV operate efficiently for small ad hoc wireless networks, their ON per-flow control overhead limits deployment on larger-scale networks. Deployment of compact routing protocols such as geographic routing has met with challenges. This paper presents Table Attenuation Routing Protocol TARP, a protocol that combines...

Troubleshooting Microsoft Windows XP-Based Wireless Networks in the Small Office or Home Office

Because small office/home office SOHO wireless networks do not have servers to perform automated configuration and verify authentication credentials, in many cases the configuration of wireless networks is done manually, which can introduce errors relating to mismatched authentication and encryption settings. Other issues such as signal interference and signal attenuation...

Link-Level Measurements From an 802.11b Mesh Network

This paper analyzes the causes of packet loss in a 38-node urban multi-hop 802.11b network. The patterns and causes of loss are important in the design of routing and error-correction protocols, as well as in network planning. The paper makes the following observations. The distribution of inter-node loss rates is...
