Analysis of Quality of Service for the AOMDV Routing Protocol
Authors: Kute V. B. , Kharat M. U. 
Published: November 2020

Due to the dynamic nature of Mobile Ad-hoc Networks (MANETs), the provision of Quality of Service (QoS) guarantees is challenging. The route failure probability in a MANET is increased due to the mobility of nodes, which increases routing overhead. Multi-path routing protocols have relatively greater ability to reduce the routing overheads. This paper discuses the performance analysis of the Ad-hoc On-Demand Multi-Path Distance Vector (AOMDV) routing protocol. AOMDV is a multi-path extension of a very well known single path routing protocol, (AODV). Extensive simulations were carried out using ns-2.34 and the study concluded that for CBR traffic AOMDV performance degrades as the data packet generation rate increases.

Published: November 2020

One of the major problems affecting municipalities is solid waste management. There is a difficulty in selecting suitable sites for waste disposal as it involves different factors to be considered before site selection. Currently, waste generation in Johor Bahru has steadily increased over the last few years and the only existing sanitary landfill is reaching its capacity limits, which means that a new sanitary landfill site needs to be constructed. In this study, geographic information system (GIS) and analytical hierarchy process (AHP) methods were utilized with the integration of dynamic data such as future population and projection of waste production in order to provide suitable sites for the construction of a sanitary landfill in the study area. Thirteen criteria were considered for this study, namely water bodies, soil, geology, slope, elevation, residential areas, archeological sites, airports, population, road, railway, infrastructure, and land use. AHP was used to determine the weights for each criterion from the pairwise comparison matrix. Consistency index and consistency ratio were checked and confirmed to be suitable. The results obtained from AHP were assigned to each criterion in GIS environment using weighted overlay analysis tool. The final potential site map was produced, and the three most suitable potential landfill sites were identified.

Conformal Band-Notch UWB Monopole Antenna on Finite Cylindrical Substrates
Authors: Ahmed E. S. 
Published: November 2020

A microstrip-fed new UWB monopole antenna with a band-notch characteristic mounted on the finite cylindrical surface is presented. The proposed antenna consists of a rectangular metal radiation patch fed by a 50 ohm microstrip line and a rectangular ground plane. To achieve ultra-wideband, three modifications are introduced. The first one is to blend the upper and lower corners of the radiating plates. The second one is to remove a circular section from the radiating metal. The third one is to blend the upper corners of the ground plane. The antenna is designed on a substrate with dielectric constant εr=3 and 1.6 mm height. The proposed antenna is conformed on finite cylindrical substrates of radiuses 4, 5 and 6 cm. The cylindrical structures were simulated through CST microwave studio finite element package. The simulation results, obtained via CST package on the return losses, VSWR and radiation pattern of the antenna are presented. For both planar and conformal antennas, results show that the impedance bandwidth of the designed antenna is from 2-18 GHz with a return loss less than -10 dB (VSWR<2) and a band rejection of 5-6 GHz for wireless LAN (WLAN), that includes the band 5.15-5.825 GHz limited by IEEE 802.11.a and HIPERLAN/2 with return loss greater than -10dB. The proposed simple shaped conformal antenna provides a good radiation pattern and gain between 3.84 and 5.96 dBi over the entire frequency band excluding the rejected band.

Published: November 2020

Epoxy resin and mica sheets consist the essential insulation of rotating machine stator bars. Such an insulation, although very resistant to partial discharges, is subjected to considerable electrical stresses and consequently electrical trees may ensue. In this paper, an effort is made to simulate electrical tree propagation in multiple epoxy resin/mica sheets with the aid of Cellular Automata (CA). An attempt to compare the simulation results with experimental results is also made.

The study concluded that the continuous maintenance of machines is considered more than necessary in the institution to reduce the cost of machine failure and their consequences to avoid falling into the problem of lack of productivity on the one hand, and on the other hand, continuous maintenance avoids the institution to bear large sums of money in the purchase of new machines and the risk of loss of customers.
Algoritmo de Monte Carlo Tree Search para SSPs sob o critério GUBS
Authors: Crispino Gabriel , Freire Valdinei , Valdivia Delgado Karina 
Published: November 2020

Em planejamento probabilístico, um problema comum é o de caminho estocastico mais curto (SSP), no qual se deseja encontrar políticas que chegam a uma meta com o menor custo acumulado esperado. A presença de estados a partir dos quais não é possível alcançar uma meta, os dead-ends, torna esse critério indefinido nesses estados. Por isso, existem extensões e novas formulações para esse caso particular, como o critério GUBS. Embora existam algoritmos para solucionar esse critério, todos eles necessitam iterar pelo espaço completo de estados. Tendo isso em vista, no presente trabalho é proposto o UCT-GUBS, um algoritmo online de planejamento baseado no UCT para resolver SSPs sob o criterio GUBS. Os resultados dos experimentos realizados mostram empiricamente que o algoritmo demonstra um compromisso entre custo e probabilidade para a meta conforme a variação dos seus parâmetros, podendo tomar uma decisão em um tempo menor ou maior dependendo do tempo limite passado para o algoritmo, que é uma característica importante do UCT.

Published: November 2020

Introduction
Family caregivers (FCGs) play an integral, yet often invisible, role in the Canadian health-care system. As the population ages, their presence will become even more essential as they help balance demands on the system and enable community dwelling seniors to remain so for as long as possible. To preserve their own well-being and capacity to provide ongoing care, FCGs require support to the meet the challenges of their daily caregiving responsibilities. Supporting FCGs results in better care provision to community-dwelling seniors receiving health-care services, as well as enhancing the quality of life for FCGs. Although FCGs rely upon health-care professionals (HCPs) to provide them with support and services, there is a paucity of research pertaining to the type of health workforce training (HWFT) that HCPs should receive to address FCG needs. Programs that train HCPs to engage with, empower, and support FCGs are required.
Objective
To describe and discuss key findings of a caregiver symposium focused on determining components of HWFT that might better enable HCPs to support FCGs.
Methods
A one-day symposium was held on February 22, 2018 in Edmonton, Alberta, to gather the perspectives of FCGs, HCPs, and stakeholders. Attendees participated in a series of working groups to discuss barriers, facilitators, and recommendations related to HWFT. Proceedings and working group discussions were transcribed, and a qualitative thematic analysis was conducted to identify key themes.
Results
Participants identified the following topic areas as being essential to training HCPs in the provision of support for FCGs: understanding the FCG role, communicating with FCGs, partnering with FCGs, fostering FCG resilience, navigating healthcare systems and accessing resources, and enhancing the culture and context of care.
Conclusions
FCGs require more support than is currently being provided by HCPs. Training programs need to specifically address topics identified by participants. These findings will be used to develop HWFT for HCPs.
Outcomes with Biological Disease-Modifying Anti-Rheumatic Drugs (bDMARDs) in Older Patients Treated for Rheumatoid Arthritis
Authors: Akter Ripa , Maksymowych Walter P. , Martin M. Liam , Hogan David B. 
Published: November 2020

Background
Biological disease-modifying antirheumatic drugs (bDMARDs) are recommended for rheumatoid arthritis (RA), but older patients reportedly experience more adverse events (AEs) and show variable treatment response. The objective of this study was to evaluate AEs and effectiveness of bDMARDs in a cohort of older patients.
Methods
AE and treatment effectiveness (based on DAS28 scores) data from a prospective provincial pharmacovigilance program for the years 2006–2009 in patients 55–64, 65–74, and 75+ years of age were compared. An intention to treat analysis with chisquare and unpaired t-testing for significance was performed.
Results
There were a total of 333 patients (156 were aged 55–64, 125 were 65–74, 52 were 75+). Those 75+ had higher disease activity and worse functional status at baseline. Among those 75+, AEs with bDMARDs were more common and likely to lead to discontinuation of therapy, be graded as severe, and classified as infectious (p < .05). Remission rate among those 75+ was significantly higher than patients 65–74. Etanercept was the most commonly used drug in all age groups.
Conclusion
Patients 75+ treated with bDMARDs are at a significantly greater risk of AEs, including infectious ones. The higher remission found in the oldest age group warrants further study.

Aim. The study presents the results of the research on the productivity features and adaptability parameters of domestic corn hybrids under different irrigation modes and water supply under conditions of the Arid Steppe. Methods. The general scientific, special selection genetic, computational and comparative research methods were used. The research object was modern corn hybrids of domestic selection of different maturity groups. The hybrids were sown under different irrigation modes (common sprinkling, drip irrigation, sub-irrigation). Results. The retrospective analysis of the productivity of main grain crops in the area of the Arid Steppe over a 130-year period showed that the highest rates of an increase in productivity were recorded in corn. An annual increase in its productivity was 31 kg/ha per year and it was due to the use of new varieties (hybrids) and the improvement of growing techniques. Irrigation made it possible to realize potential productivity of new hybrids and increase the productivity from 6.59 to 82.3 c/ha. Productivity rose 12.5 times over a 130-year period, the annual increase being 58 kg/ha per year. Without irrigation the grain productivity was the highest in early-maturing hybrids – 3.28 and 3.05 t/ha indicating their high drought resistance. The use of these hybrids is appropriate under conditions of water-saving irrigation modes on irrigated lands with a low hydro-module and on dry massifs. A fall in the productivity under other irrigation modes was from 0.41 to 1.93 t/ha. Conclusions. Under irrigation conditions it is necessary to use corn hybrids with a genetically programmed reaction to optimal growing conditions (an optimal mode of soil moisture and mineral nutrition).
Keywords: hybrid, corn, irrigation, adaptability, drought resistance, grain, selection.
