In the concern of the preservation of the main historic monuments of the cities of Rabat and Sale (Morocco), a botanical study was conducted in 2009. The prospecting of these monuments allowed raising an inventory of the flora populating their building materials, and it has proved that this flora is rich and diversified. Indeed, it consists of 171 adventitious species distributed in 46 botanical families. The most represented families are Asteraceae, Poaceae, Fabaceae, Caryophyllaceae, Geraniaceae, Brassicaceae and Lamiaceae. They supply, to them only 49.7% of the specific size. The annual therophytes and the dicotyledon are dominant with respectively 66.7% and 84.7% of the specific size. Nevertheless, the presence of more than 20 species of trees and perennials constitutes a serious danger for bulwarks walls, especially by the phenomenon of fissuring by the action of the huge roots of these vegetables. These vegetables fitting into are placed on joints or cracks fissures have a chemical action on stones by acids that they release, and also a mechanical action by the growth of roots inside cracks fissures. They remain one of these are one of the important biological factors of the degradation of historic monuments. It is to note that the bulwarks walls of the site of Chella (Roman ruins) present more floral diversity than the other canvassed monuments (91 species) that are 53% of the total size.

Model Predictive Control for Discrete and Continuous Timed Petri Nets

引用

International Journal of Automation and computing 2018年第1期15卷 25-38页

作者： Marwa.taleb Edouard Leclercq Dimitri Lefebvre Laboratory GREAH University of Le Havre

The goal of this paper is to propose a unique control method that permits the evolution of both timed continuous Petri net （TCPN） and T-timed discrete Petri net （T-TDPN） from an initial state to a desired one. Model predictive control （MPC） is a robust control scheme against perturbation and a consistent real-time constraints method. Hence, the proposed approach is studied using the MPC. However, the computational complexity may prevent the use of the MPC for large systems and for large prediction horizons. Then, the proposed approach provides some new techniques in order to reduce the high computational complexity; among them one is taking constant control actions during the prediction.

Using passive cooling strategies to improve thermal performance and reduce energy consumption of residential buildings in U.A.E. buildings

引用

Frontiers of Architectural Research 2014年第2期3卷 154-165页

作者： Hanan M. taleb Faculty of Engineering British University in Dubai Dubai 502216 UAE

Passive design responds to local climate and site conditions in order to maximise the comfort and health of building users while minimising energy use. The key to designing a passive building is to take best advantage of the local climate. Passive cooling refers to any technologies or design features adopted to reduce the temperature of buildings without the need for power consumption. Consequently, the aim of this study is to test the usefulness of applying selected passive cooling strategies to improve thermal performance and to reduce energy consumption of residential buildings in hot arid climate settings, namely Dubai, United Arab Emirates. One case building was selected and eight passive cooling strategies were applied. Energy simulation software namely IES was used to assess the performance of the building. Solar shading performance was also assessed using Sun Cast Analysis, as a part of the IES software. Energy reduction was achieved due to both the harnessing of natural ventilation and the minimising of heat gain in line with applying good shading devices alongside the use of double glazing. Additionally, green roofing proved its potential by acting as an effective roof insulation. The study revealed several significant findings including that the total annual energy consumption of a residential building in Dubai may be reduced by up to 23.6% when a building uses passive cooling strategies.

Experimental and statistical investigation of a new concrete-composite beam with encased polymer tube wrapped by FRP

引用

Frontiers of Structural and Civil Engineering 2015年第2期9卷 154-162页

作者： Abdelmadjid SI SALEM Souad AIT taleb Kamal AIT TAHAR Laboratory LaMoMS the University Mouloud Mammeri of Tizi Ouzou Tizi Ouzou 15000 Algeria

A new concrete-composite beam with high mechanical performances to weight ratio is developed in this study. The proposed design technique consists to embed a cylindrical polymer tube wrapped by a GFRP Jacket in the mechanically ineffective concrete tensile zone. An experimental investigation is carried out on composite beams under bending loads until failure to evaluate the flexural capacity and the corresponding failure mechanisms. Based on the experimental results, statistical and preliminary reliability analyses using the FORM method are performed to assess the safety margin of the new beam. The confrontation between test and simulation results shows a satisfactory agreement, and represents a promising revelation regarding the improvement in terms of strength and ductility of such design compared to conventional reinforced concrete beams with traditional one.

New stem cell based therapies are undergoing intense research and are widely investigated in clinical fields including the urinary system. The urinary bladder performs critical complex functions that rely on its highly coordinated anatomical composition and multiplex of regulatory mechanisms. Bladder pathologies resulting in severe dysfunction are common clinical encounter and often cause significant impairment of patient's quality of life. Current surgical and medical interventions to correct urinary dysfunction or to replace an absent or defective bladder are sub-optimal and are associated with notable complications. As a result, stem cell based therapies for the urinary bladder are hoped to offer new venues that could make up for limitations of existing therapies. In this article, we review research efforts that describe the use of different types of stem cells in bladder reconstruction, urinary incontinence and retention disorders. In particular, stress urinary incontinence has been a popular target for stem cell based therapies in reported clinical trials. Furthermore, we discuss the relevance of the cancer stem cell hypothesis to the development of bladder cancer. A key subject that should not be overlooked is the safety and quality of stem cell based therapies introduced to human subjects either in a research or a clinical context.

学位级别：硕士

Around the world, telecom providers are transforming their networks to deliver next-generation services. In their future networks, fiber optic wires, rather than copper,will run all the way to customers' homes and businesses. Most of them have already started building these fiber optic connections - called fiber to the home (FTTH)-because they know that only FTTH can meet the exploding demand for broadband services. Consumers who subscribe to FTTH consistently rate it as the fastest and most reliable broadband technology. They also appreciate that fiber networks can deliver many unique broadband services for medicine, education, home-based businesses, home automation and entertainment. Over the last few years, businesses have made a massive shift to "cloud services." For economic efficiency,their critical systems now operate at huge remote data centers rather than on-site computers. The speed, reliability and security of fiber connections make cloud services ***, fiber connections are available to more than 200 million homes globally - a tenth of all the households in the world - and worldwide, an estimated 107 million households subscribe to fiber-based services, including voice,video, data and *** the United States,one of every five households is within reach of fiber,and nearly 10 million households are using FTTH services now. These numbers continue to grow rapidly. China alone expects to have fiber broadband available to 200 million households by 2015 and to 300 million by 2020. It expects to have 70 million FTTH subscribers by the end of 2015, with gigabit speeds available in some of the larger cities. Other nations are also embarking on aggressive FTTH *** first time fiber delivered a signal directly to a home (in Hunter's Creek, Fla.)was more than 25 years ago.

Micro-phytoplankton distribution and biomass in and around a channel-based fish farm: implications for sustainable aquaculture

引用

Acta Oceanologica Sinica 2014年第12期33卷 180-191页

作者： SADALLY S. B NAZURALLY N taleb-HOSSENKHAN N BHAGOOLI R Department of Biosciences Faculty of Science University of Mauritius Department of Marine and Ocean Science Fisheries and Mariculture Faculty of Ocean Studies

Micro-phytoplankton density, genera composition, chlorophyllaconcentration, and physico-chemical pa-rameters were investigated at five stations （S1-near the coast; S2 and S4-at the edges of the aquaculture set-up; S3-in the center of the set-up; and S5-nearby patch of corals） in and around a coastal channel-based fish farm. The highest total micro-phytoplankton density （TPD）, including diatoms, dinoflagellates and cyanobacteria, was recorded at S3 （（6.28±2.00）×10^6 cells/L） followed by S4 （（5.87±2.81）×10^5 cells/L）, S1 （（4.92×10^5±8.70×10^4） cells/L）, S5 （（3.54×10^5±5.33×10^4） cells/L） and S2 （（2.60±1.14）×10^5cells/L）. Chlorophyll a and nutrient concentrations were highest at S3 and were positively correlated with TPD. Among the 35 genera documented in this study,Chaetoceros spp. was the dominant diatom whilePeridinium spp. was the most dominant dinoflagellate. Very low densities of toxic bloom-forming dinoflagellates were encountered during this study. These results suggest that occurrence of non-bloom densities of micro-phytoplankton, possibly due to the natural flushing of the existing lagoonal channel at the aquaculture site, yielded in little environmental impact and can represent an appropriate sustainable approach for future aquaculture de-velopment.
