In the State of Qatar, the intense and rapid urban development based on hosting upcoming mega events, as envisioned by Qatar‟s National Vision (QNV- 2030), have raised concern about community stability as it faces modernization in both physical and social aspects. A declining sense of community amid has been associated with interactions within urban amenities and form that trigger social problems, diminish a community‟s well-being and delay development. The integration of a community within the urban physical realm contributes to the development of sustainable communities. The research study aims to identify major urban concepts that contribute to resilience in both socio economic and demographic context. Qualitative community sustainability is investigated in Al-Wakrah city neighborhood through site visits, observation and interviews in order to establish a measure for urban characteristics that are catalysts for sustainable community development in future urban planning decisions.

The Fibonacci sequence is famous because it’s have amazing and great properties. In this study, we prove some of the interesting properties which include the relations between Fibonacci numbers and (9, 19, 29). And we found a lot of connections between them.

This study, which examines the productivity of Lagoon cattle farms located on the islands at risk of flooding in the municipality of Sô-Ava in the Oueme river valley in southern Benin, took place between November and December 2016. It concerns 95 farms of bovine Lagoon distributed on the various islands of the Municipality. These operations have a total of 2496 head of Lagoon cattle herds. It aims to compare the demographic parameters obtained on the different islands during the last year and that of 2010 where the island experienced a flood. Data were collected from a 12-month retrospective survey (12MO). The annual demographic parameters (annual rate, calving, abortion, stillbirth, mortality, annual net growth, annual exploitation rate and annual rate of multiplication) were calculated and analyzed under software R3.3.2. Thanks to the t12mo package. Except for the mortality rate, there were no significant changes in reproductive rates (p> 0.05) regardless of the herd of residence of the herds. The annual mortality rate was significantly higher (p <0.05) on the Dekanmey, Houedo and Sô-Ava islands compared to that of the Ahomey Lokpo island (0.124, 0.142, 0.113, vs 0.071an-1). The year had a significant effect on the demographic parameters (p <0.05) as well as on the overall demographic indicators obtained. Implementation of a resilient model to climate shocks would be an incentive for the sustainable management of these farms.

This paper is deals with the robustness property of various intelligent control methods namely Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Bacterial Foraging Algorithm (BFA), and Harmony Search Algorithm (HSA) for the design of Power system stabilizer for multi machine power system. The problem of robustly tuning of PID based stabilizer design is formulated as an optimization problem according to the time domain-based objective function with some performance indices which is solved by intelligent control methods that have a strong ability to find the most optimistic results. To demonstrate the effectiveness and robustness of the proposed stabilizers, the design process takes a wide range of operating conditions and system configuration into account. The comparison is carried out in terms of robustness, peak over shoot and settling time of the system dynamic response. For completeness, the performance of conventional controllers is also included. The results of these studies show that the proposed intelligent control methods based PID type stabilizers have an excellent capability in damping power system oscillations and enhance greatly the dynamic stability of the power system in addition to maintaining robustness for a wide range of loading conditions.

Debacle reaction and recuperation endeavors require auspicious association and coordination of open crisis benefits so as to spare lives and property. Today, IT is utilized as a part of this field just to a restricted degree; however there is a huge potential for expanding productivity and viability in adapting to a calamity. In this paper we outline necessities and imaginative innovation for an incorporated fiasco administration correspondence and data framework, tending to specifically arrange, setup, planning and information administration issues amid the reaction and recuperation stages.

This paper utilized the compressive tests results to examine the crushing behaviour of wood ash particles (hardwood) reinforced polypropylene (WARPP) for crash energy management. The study employed Taguchi method of experimental design to generate data for the work. Gauss – Legendre two point rules was used to evaluate the area under the stress – strain curves which measured the amount of energy absorbed per unit volume of sample. With this evaluation method the highest ultimate strength of 10.5384J/m3 with corresponding work absorption of 1.1 x 10-5J was obtained. Also established with the compression data was the specific energy absorption of 0.01038J/Kg and compressive modulus of 4.9885N/mm2.

This study conducted to assess water quality by using Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI). Study area involves four districts (Almusayab, Almahaweel, Almuharibeen and Aljamiyaa) located in Babylon governorate. Samples collected during three months starting from January 2016 until March 2016 and analyzed for many physical and chemical properties included PH, Calcium (Ca), chloride (Cl), total Hardness (TH), sulfate (SO4), total dissolved solid (TDS) and magnesium (Mg). The calculated values of CCME WQI showed that the water quality of study area in four districts (Almusayab, Almahaweel, Almuharibeen and Aljamiyaa) were good according to CCME WQI classification during study period and measured values of chemical and physical properties were within Iraqi standards.

Many renewable energy-based systems are being used to increase the utilization of renewable energy as they have huge potential nowadays; the investigation of the utilization of fuel cells and solar energy in cars are important where the investigation and understanding of the technical aspects are crucial such as how the flow of electrons creates direct electric current in both fuel cells and photovoltaic systems. In this article, a prototype of a car used hydrogen produced on board by analyzing water. This hydrogen used to operate a fuel cell that generates electricity capable to run a car. The characteristic curves of the fuel cell were measured and evaluated. The results show that this type of cars can be promising in the next few years.
