To study the performance of soybean (Glycine max L.) cultivars in varying weeding regimes, a field experiment was conducted in 2010. The experiment was split plot in a randomized complete block design with 3 replicates. The four cultivars and two lines of soybean including: Sahar, Hill, Sari, Telar, 032 and 033 in main plot and weeding regime consist of no weeding (control), one weeding (35 day...

This paper describes a robust speech documents retrieval system that uses voice input keywords. To solve the inevitable problems which arise when the input to the system is speech, i.e. misrecognition, a novel method was developed, where, before the retrieval processing, unproductive keyword candidates are discarded by a grouping processing using the similarity between words and the recognition...

We present, prove correctness for, and evaluate a protocol for the reliable broadcast of topology and link-state information in a multihop communication network with a dynamic topology, such as a wireless network with mobile nodes. The protocol is called Topology Broadcast based on Reverse Path Forwarding (TBRPF), and uses the concept of reverse-path forwarding (RPF) to broadcast link-state upd...

In our Scheme cloud computing users has to get Key information to Re Encrypt the data which has been in Encrypted to get Key information in order to decrease the number of keys used we are proposing Broadcast encryption Broadcast encryption is the cryptographic problem of delivering encrypted content over a broadcast channel in such a way that only qualified users can decrypt the content. The c...

Salinity level may affect early development of biofuel feedstock crops. The biofuel feedstock crops canola (Brassica napus L.), sorghum [Sorghum bicolor (L.) Moench], and sunflower (Helianthus annuus L.); and the potential feedstock crop sweet corn (Zea mays L.) were planted in media in pots and treated with aqueous solutions of 0, 0.1, 0.5 and 1.0 M NaCl once at: 1) planting; 2) 7-10 days afte...

We apply multiple query optimization to batches of pull (on-demand) requests in a mobile database system. The resulting view can answer several queries at once, and it is broadcast on a view channel dedicated to common answers of multiple queries rather than over individual downlink channels. A performance study is conducted that simulates different query workloads. The results indicate a signi...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

In this paper, we study the Minimum Latency Broadcast Scheduling (MLBS) problem in wireless sensor networks (WSNs). The main issue of the MLBS problem is to compute schedules with the minimum number of timeslots such that a base station can broadcast data to all other sensor nodes with no collisions. Unlike existing works that utilize the traditional omni-directional WSNs, we target the directi...
