Road infrastructure is an important sector of economic activity for the development of a country. The road infrastructure is required to be maintained in proper condition to ensure its continuous utilization in proper manner. By proper maintenance of roads, continuous acceptability, a higher economy, safety and serviceability are gained. This research work was carried out through analysis of data collected from Department of Road (DoR) Nepal and surveyed through Google Earth. While analyzing data, data are categorized according to road type and pavement surface with spatial coverage. It mainly deals with the using of Road Economic Decision (RED) model, in which Highway Development and Management (HDM)-4 VOC model (Version 3.2) is used for computing coefficient of Vehicle Operating Cost (VOC) and RED Main Economic Decision model is used to compute value of International Roughness Index (IRI) for optimum maintenance strategy for strategic road network of Nepal with low traffic volume. The outcome of analysis will help the concern authority to make good decision on making priority and economical selection of maintenance strategy for the road having specified range of IRI value depending on the pavement type, surface type and volume of vehicle with spatial coverage.

Road infrastructure has witnessed incremental changes in the past as compared to the immense development witnessed by the vehicle’s safety technology. Bott’s dots and other reflector devices are extensively used on the road infrastructure for lane separation and for improving edge detection. These devices come in a large variety of shapes and sizes, however, all of them fall under the category of retroreflectivity since they depend on vehicle lights to provide reflection. Glow-in-the-dark (GiD) material has the benefit that it can store energy during the presence of light and can emit the stored energy in the form of visible light in the absence of an external light source. In this regard, the presented research work details the development and testing of GiD concrete based markers that can be used for lane separation and edge detection. The benefit of the presented innovation is that GiD concrete based markers can be used for visible light instead of retroreflectivity in addition to acting as a driver alertness tool. The durability performance of the presented innovative GiD based raised pavement markers has been presented along with cost comparison to traditional Bott’s dot. In addition, the presented prototype can be adopted for various architectural and esthetical applications in buildings, parks, walkways and bicycle lanes etc.

Self Driving Cars

Self-driving vehicles are one of the emerging technologies. This technology has potential to save lives and make lives comfortable. However, the technology used in self driving cars has to perform series of task for building perceptions. This has some certain prerequisites related to road infrastructure and is affected by daylight and weather conditions of the place. If these prerequisites are not satisfied then it could affect the performance of the vehicle and can be considered as compromise with safety of the users. This research work is focused on trying to find a new approach using which the underdeveloped countries will also be able to implement self driving cars in their county. The objective of this paper is to propose a new approach to supplement the technology used in the self-driving cars for perception. Using this approach the countries who don’t satisfy the prerequisites would be eligible to implement them without compromising the safety.The proposed approach uses the technology Augmented Reality to create and augment artificial objects of navigational signs and traffic signals based on vehicles location to reality. Later the augmented scene is fed into the conventional Deep learning object detection algorithm to detect the navigational artificial objected along with other real objects. This approach help navigate the vehicle even if the road infrastructure does not have very good sign indications and marking.The approach was tested locally by creating a local navigational system and a smartphone based augmented reality app. The approach performed better than the conventional method as the objects were clearer in the frame which made it each for the object detection to detect them.

ABSTRACTA review of the educational literature on naive concepts about principles of chemistry and physics and surveys of science museum visitors reveal that people of all ages have robust alternative notions about the nature of atoms, matter, and bonding that persist despite formal science education experiences. Some confusion arises from the profound differences in the way that scientists and the lay public use terms such as materials, metals, liquids, models, function, matter, and bonding. Many models that eloquently articulate arrangements of atoms and molecules to informed scientists are not widely understood by lay people and may promote naive notions among the public. Shifts from one type of atomic model to another and changes in size scales are particularly confusing to learners. People's abilities to describe and understand the properties of materials are largely based on tangible experiences, and much of what students learn in school does not help them interpret their encounters with materials and phenomena in everyday life. Identification of these challenges will help educators better convey the principles of materials science and engineering to students, and will be particularly beneficial in the design of the Materials MicroWorld traveling museum exhibit.

Employment Pattern

The barani (rain-fed) region accounts for about a fifth of the cultivated area in Pakistan. It has the potential to significantly increase crop production levels. Similarly, considerable scope exists in this area for the development of forests, fruit and vegetable gardening, pasture and stock rearing. Most of the natural resources are also found in this tract. Its hilly areas possess a vast potential for tourism. Besides, significant opportunities exist for irrigation and hydroelectric power generation. An optimum utilisation of all this potential, obviously, is employmentgenerating and income-augmenting. Despite all such realisations this region as a whole, unfortunately, is identified as the least attended to area in terms of provision of socio-physical infrastructure, other development programmes and, even, research work. This led to a deterioration of the employment situation in the barani region as a whole. A poor information base and analysis thereof on employment and manpower related variables is also the consequence of such a treatment to this area. I This paper, using the data of a field survey, tries to fill, though partly, the vacuum on employment and related variables in the rural barani region. An attempt is made here to record and analyse the labour force participation rates, employment pattern (main economic activities) and unemployment/underemployment levels prevailing in the rural baran; areas of the provinces of the Punjab and North-West Frontier Province (NWFP).
