Maize is one of the most important staple crops in highlands Andean region Ecuador, Peru, and Bolivia. Most seeds come from landraces, with their own kernel characteristics. The kernels are used for elaboration traditional dishes other elaborates human consumption. In this region, maize breeding conducted mainly by public institutions. review, we outline methodology that has been programs (MBPs...

⎯ This paper presents a model-based Register Transfer Level (RTL) design of a 4x2 Multiple-Inputs Multiple-Outputs (MIMO)-Orthogonal Frequency Domain Multiplexing (OFDM) wireless communication systems transmitter and its Field Programmable Gate Array (FPGA) implementation. This system provides a maximum of 600 Mbps with 20 meter of propagation distance using 80 MHz baseband bandwidth with 4x2 M...

This paper examines the asymmetry effects of third user interference on IrDA FIR links at 4 Mbps employing 4PPM encoding. The analysis examines the variation in the interference-signal ratio (ISR) with the distance and orientation of an interfering device which affects the error probability of the PPM symbol.

This paper presents performance evaluation of commercially available 200 Mbps power line communication and IEEE 802.11g & n products for supporting multimedia database system for home environment. UDP and TCP protocol were used to measure the throughput of each technology. The Homeplug AV product shows highest UDP and TCP throughput results and all products provide full connectivity for all mea...

This paper presents a comprehensive evaluation of the performance super-large-coverage mobile communication system for wireless regional area networks (WRANs) in very-high-frequency (VHF) band. The was standardized as ARIB STD-T103 and IEEE 802.16n. It can transmit data over distance 10 km or more at transmission rate several megabits per second (Mbps). is particularly suitable transmitting sen...

Assuming that the IEEE 802.11 Wireless Local Area Networks (WLANs) are based on a radio/infrared link, they are more sensitive to the channel variations and connection ruptures. Therefore the support for multimedia applications over such WLANs becomes non-convenient due to the compliance failure in term of link rate and transmission delay performance. Voice and broadband video mobile transmissi...

TreadMarks is a distributed shared memory (DSM) system for standard Unix systems such as SunOS and Ultrix. This paper presents a performance evaluation of TreadMarks running on Ultrix using DECstation-5000/240's that are connected by a 100-Mbps switch-based ATM LAN and a 10-Mbps Ethernet. Our objective is to determine the e ciency of a user-level DSM implementation on commercially available wor...

OBJECTIVE To determine if acute pain response after administration of the diphtheria, polio, and tetanus toxoids and acellular pertussis and Haemophilus influenzae type b (DPTaP-Hib) vaccine and the pneumococcal conjugate vaccine (PCV) is affected by the order in which they are given. DESIGN Single-center, double-blind, randomized clinical trial. SETTING Outpatient pediatric clinic in Toron...

Wireless APs have become very popular in networking multiple devices at home and allow multiple individuals to share the Internet connections, doing different tasks simultaneously. People use not only desktop and laptop computers but also many other devices with network capabilities. These devices include gaming consoles, portable gaming consoles, Voice-over-IP (VoIP) phones, video streaming se...
