Worldwide Interoperability for Microwave Access (WiMAX) embodies the IEEE 802.16 family of standards that provide wireless broadband access to residential and commercial Internet subscribers. While other WiMAX applications exist, there is an increasing trend to employ WiMAX for last-mile Internet access to circumvent the high deployments costs and local loop distance limitations associated with...

This document reports on our preliminary study of the power consumption of typical household networking equipment under different operational modes. Three ADSL modems are studied: Cisco 837, Linksys AG041 and Linksys WAG54G. We consider each modem’s power consumption when it is being in the Minimum Load (powered on with no physical ADSL/Ethernet connections), Idle (powered on with ADSL/Ethernet...

In this paper, a design for Asymmetric Digital Subscriber Line (ADSL)/Asymmetric Digital Subscriber Line2 (ADSL2) Initialization Process is presented which can be applied to different telephone network. Such a proposal can face the different types of noise over DSL channels, the most important types are Background and Crosstalk noises and Inter symbol interference (ISI) which is eliminated by u...

Korean cattle (Hanwoo) are categorized into three breeds based on color: brown, brindle, and black. Among these breeds, brown Hanwoo has been subjected to intensive selection to improve meat traits. To identify genetic traces driven by recent selection in brown Hanwoo, we scanned the genomes of brown and brindle Hanwoo using a bovine SNP chip. We identified 17 candidate selection signatures in ...

The IEEE 802.16 Worldwide Interoperability for Microwave Access (WiMAX) standard is widely used for fixed and mobile Internet access. WiMAX provides maximum data rate of 75 Mbps and high-speed Internet access to a wide range of devices used by clients over the last mile. Asymmetric Digital Subscriber Line (ADSL) is widely used to provide guaranteed service. In this paper, we compare performance...

This paper presents a simulation model of a binder of asymmetric digital subscriber lines (ADSL). The model is developed in the Simulink environment and enables the investigation of multicarrier communication aspects in the complex system of a loop binder interconnecting the customer premises with the nearby central office. Key features of the model architecture are the update of the model bloc...

Nowadays, is more and more usual to implement the voice service over Internet (VoIP), due to the reduction in price both for the network operator and for the final users. In this paper, it is presented a new traffic shaper that increases the number of stablished connections and minimizes the delay time in the case of using an IP/ADSL (Internet Protocol/Asymmetric Digital Subscriber Line) enviro...

We conduct an empirical analysis of quality competition between broadband Internet Service Providers (ISPs), using National Broadband Map data for 2011-2013 for almost a thousand local markets in California. We examine how incumbent ADSL firms respond to competition from CLECs and cable modem service providers. We use an important quality attribute, the downstream data rate, and estimate the st...

Adenylosuccinate lyase (ADSL) deficiency is an autosomal recessive disorder caused by mutation in the ADSL gene. The disease was identified in 1984 by Jaeken and van der Berghe as the first inborn defect of purine biosynthesis. Affected children revealed encephalopathy with epilepsy and marked psychomotor retardation. A neurological examination showed hypotonia, followed sometimes after years b...
