As the popularity of IEEE 802.11-based Wireless Mesh Networks (WMNs) grows, end users of these environments demand better performance and quality of service (QoS). However, the Medium Access Control (MAC) layer of the IEEE 802.11 standard was not initially designed to provide either multihop or QoS capabilities. Therefore, the performance of IEEE(More)
A central composite factor design was used to examine the influence of independent variables in the acetone pulping of wheat straw (processing temperature, time, and acetone concentration) on the yield of the resulting pulp, and on various physical properties of paper sheets (breaking length, stretch, burst index, tear index and brightness) obtained from(More)
In this work, we studied the influence of operational variables in the bleaching of soda pulp of Musa textilis nee (abaca) [viz. temperature (55-85 degrees C), bleaching time (30-150 min) and peracetic acid concentration oven dry pulp (0.5-4.5%)] on the kappa number and viscosity of the bleached pulp, as well as on the breaking length, burst index and(More)
The influence of temperature (150-170 degrees C), pulping time (15-45 min) and soda concentration (5-10%) in the pulping of abaca on the yield, kappa, viscosity, breaking length, stretch and tear index of pulp and paper sheets, was studied. Using a factorial design to identify the optimum operating conditions, equations relating the dependent variables to(More)
This paper reports on the influence of independent variables in the ethylene glycol/soda pulping of olive wood trimmings [viz. cooking temperature (165–195°C) and time (30–90 min), ethylene glycol concentration (5–15%), soda concentration (2.5–7.5%), and liquid/solid ratio (4/1–6/1)], on the yield and viscosity and holocellulose, -cellulose, and lignin(More)
Lack of flexibility of current Internet architecture led researchers to come up with new paradigms for a novel Internet architecture, which would be able to reduce complexity and increase flexibility compared to current Internet architecture. Functional composition is a promising approach to flexible and evolvable architecture design. The idea is composing(More)
OBJECTIVE To assess the prognostic value of the therapeutic response by (11)C-choline PET/CT in prostate cancer patients with biochemical recurrence in which (11)C-choline PET/CT indicated radio-guided radiotherapy. METHODS The study included 37 patients initially treated with prostatectomy, who were treated due to biochemical recurrence. (11)C-choline(More)
Reactive routing protocols like ad hoc on-demand distance vector (AODV) have been widely proposed for multi-hop wireless networks (MWNs). However, these types of routing protocols only recover routes after route break detection. Considerable research efforts have been devoted to minimizing the route recovery delay or to anticipating link breaks by using(More)
