The study examined significant summer heat effects on a traditional habitation cluster within a compact fabric of the Medina of Constantine, based on building materials and spatial functional architecture. As climate relates to energy effects, the study raises the importance of possible heat gains in the approach of thermal comfort through building materials without using other energy sources. The study employed both empirical and comparative methods to undertake the research work. The empirical method consisted of taking thermal and metric measurements of the habitation cluster and comparing them with current normative requirements in sustainable architecture. The comparative method consisted of comparing results of performance assessment of studied building materials with results of similar materials. The current study adds to researchers' claims about the importance of the Medina's habitation in the face of climatic aggression at times with its architecture and building materials. Medina’s habitat did not have the technological means to preserve some physical comfort and reduce greenhouse gas emissions, yet its architecture used soft means to accomplish the physical comfort. Additionally, the site's well-chosen materials, which are formed by the natural typology, match well with the site’s climate and provide better resistance to material overflow, not to mention their availability and inexpensive cost.

The exponential increase in textile cotton wastes generation and the ineffective processing mechanism to mitigate its environmental impact by developing functional materials with unique properties for geotechnical applications, wastewater, packaging, and biomedical engineering have become emerging global concerns among researchers. A comprehensive study of a processed cotton fibres isolation technique and their applications are highlighted in this review. Surface modification of cotton wastes fibre increases the adsorption of dyes and heavy metals removal from wastewater. Cotton wastes fibres have demonstrated high adsorption capacity for the removal of recalcitrant pollutants in wastewater. Cotton wastes fibres have found remarkable application in slope amendments, reinforcement of expansive soils and building materials, and a proven source for isolation of cellulose nanocrystals (CNCs). Several research work on the use of cotton waste for functional application rather than disposal has been done. However, no review study has discussed the potentials of cotton wastes from source (Micro-Nano) to application. This review critically analyses novel isolation techniques of CNC from cotton wastes with an in-depth study of a parameter variation effect on their yield. Different pretreatment techniques and efficiency were discussed. From the analysis, chemical pretreatment is considered the most efficient extraction of CNCs from cotton wastes. The pretreatment strategies can suffer variation in process conditions, resulting in distortion in the extracted cellulose’s crystallinity. Acid hydrolysis using sulfuric acid is the most used extraction process for cotton wastes-based CNC. A combined pretreatment process, such as sonication and hydrolysis, increases the crystallinity of cotton-based CNCs. The improvement of the reinforced matrix interface of textile fibres is required for improved packaging and biomedical applications for the sustainability of cotton-based CNCs.

The addition of a photocatalyst to ordinary building materials such as concrete creates environmentally friendly materials by which air pollution or pollution of the surface can be diminished. The use of LiNbO3photocatalyst in concrete material would be more beneficial since it can produce artificial photosynthesis in concrete. In these research photoassisted solid-gas phases reduction of carbon dioxide (artificial photosynthesis) was performed using a photocatalyst, LiNbO3, coated on concrete surface under illumination of UV-visible or sunlight and showed that LiNbO3achieved high conversion of CO2into products despite the low levels of band-gap light available. The high reaction efficiency of LiNbO3is explained by its strong remnant polarization (70 µC/cm2), allowing a longer lifetime of photoinduced carriers as well as an alternative reaction pathway. Due to the ease of usage and good photocatalytic efficiency, the research work done showed its potential application in pollution prevention.

Fatigue Detection

Driver Assistance system is significant in drriver drowsiness to avoid on road accidents.  The aim of this research work is to detect the position of driver’s eye for fatigue estimation. It is not unusual to see vehicles moving around even during the nights. In such circumstances there will be very high probability that a driver gets drowsy which may lead to fatal accidents. Providing a solution to this problem has become a motivating factor for this research, which aims at detecting driver fatigue. This research concentrates on locating the eye region failing which a warning signal is generated so as to alert the driver. In this paper, an efficient algorithm is proposed for detecting the location of an eye, which forms an invaluable insight for driver fatigue detection after the face detection stage. After detecting the eyes, eye tracking for input videos has to be achieved so that the blink rate of eyes can be determined.

Intensive Approach

Infrastructural developments are inevitable for the developing countries and hence the production of sustainable building materials is promoted worldwide. Sustainable development in the vicinity of tiles is bewildered for more than a decade. Production of conventional tiles such as cement concrete tiles, clay tiles and ceramic tiles is energy intensive approach and levies lot of strain over the adjunct ecosystem. On the other hand there are serious problems related to the disposal of flyash, Rice Husk Ash throughout the world. An approach has been taken to synthesis tiles based on these industrial byproducts as the base materials through Geopolymer technology. In this work, Geopolymer mortar after heat curing is applied as tiles. In this work, Flyash is replaced by Rice Husk Ash in various proportions such as 20, 40, 60, 80 and 100 percent. Tests such as workability, flatness, straightness, perpendicularity, water absorption, modulus of rupture and abrasion are conducted and fair results are obtained. This research also portrays the effect of Rise Husk Ash addition over the flyash based Geopolymer binder in the utility as tiles. The findings of this research work encourages the development of energy efficient tiles using industrial wastes. Keywords: Geopolymer, Rice Husk Ash, Tiles

Grids can form the basis for pervasive computing due to their ability of being open, scalable, and flexible to various changes (from topology changes to unpredicted failures of nodes). However, such environments are prone to failures due to their nature and need a certain level of reliability in order to provide viable and commercially exploitable solutions. This is causing nowadays a significant research activity which is focused on the topic of achieving certain levels of Quality of Service (QoS) in highly unreliable environments (such as mobile and ad hoc Grids). This study will focus on the state-of-the-art analysis of the QoS aspects in Grids and how this is achieved in terms of technological means. A small survey and related work will be also presented. A more detailed analysis on the features of unreliable environments such as mobile Grids will be described. An innovative and efficient mechanism will be described, which is especially designed for such environments, in order to enhance them with the QoS attributes of reliability (fault tolerance through replication of tasks) and service differentiation to the Grid users through a simple task prioritization scheme. The results that this recent research work is presenting are promising for the future advancement of Grid commercialization in such environments.

Current tends in car body or rail traffic engineering aim at the realization of modern lightweight structures. In this context, demanding technological and economical requirements like the use of high strength materials, the forming of very complex geometries, and the reduction of costs, particularly with regard to low volume production, must be achieved. Novel approaches in the field of sheet metal hydroforming are able to overcome existing limitations of conventional forming technologies and feature a higher potential for an effective manufacturing of lightweight structures. This paper shows the current research work at the Institute of Forming Technology and Lightweight Construction (IUL) in the face of sheet metal hydroforming with a special focus on the design of tool systems.

Demand of the construction industry for coral rock in the Maldives will soon reach the limit of supply capacity using existing collection techniques. It is estimated that, at the current rate of consumption, the supply of living coral rock from inner atoll ‘faros’ in North Malé will be exhausted within 30 years. Current mining practice has already necessitated the collection of living coral rock from outer atoll ‘faros’ which actually protect the integrity of the islands against the erosive influences of monsoon storms.Biological surveys of mined sites (compared with controls where no mining activity has taken place) indicate a dramatic reduction in coral variety and abundance and in some cases an almost total depletion of living coral after mining. At intensively-mined sites, diversity and abundance of coral-reef fishes is also markedly reduced, with some reef species commonly used as baitfish entirely absent. The time taken for reefs to recover from mechanical damage has been shown by other research work to be extremely variable, with some cases showing no recovery in some circumstances. Shallow-water reefs that have been colonized by slow-growing ‘massive’ corals, such as those which have been mined in the Maldives, may take a minimum of 50 years to recover to their former state—under optimum conditions.Observations on mined reefs in the Maldives show that recovery over the last 10 years has been minimal, and therefore suggest that recovery times may be much in excess of 50 years. Indeed many of these reefs may not recover at all unless some attempts are made to re-establish corals at these sites. It is also clear from the study of reclaimed and dredged sites and those where less-intensive mining has taken place, that regeneration of corals is occurring. It is quite probable that the rate of recovery is dependent on the intensity of the disturbance which initially took place.Alternative building materials are available in the form of concrete blocks. Use of these blocks is more cost-effective than use of coral rock; however, there is a lack of any quality control, which would be needed to promote the widespread use of concrete blocks as a substitute for coral. Recently, recommendations have been approved by the Government of Maldives for the execution of a feasibility study on mining an inner atoll faro which could potentially provide building material for as long as the next 500 years.
