Abstract :

Bidding trend in different categories of work in Division Road Offices, Bharatpur are different. The main purpose of the research is to analyze the existing bidding trends along with the consequences of procurement at Division Road Office Bharatpur, Chitwan. Contracts were administered in Chitwan and Dhading districts. A five ranking likert scale ranging from 1(strongly disagree) to 5 (strongly agree) was adopted to capture the importance of various factors with help of Relative Importance Index (RII). For the improvement in existing bid awarding system based on scheduled questionnaire i.e. low bidding and collusive bidding, new bidding method would be introduced. Extra qualification criteria should be focused by assigning weighted in monitory term along with implementation of extra performance bond based on ranges of percentage below engineers' estimate through amendment of PPA (2007) and PPR (2007), asking method of statement and assuring for project performances before project implementation. The provision of bid capacity might improve with practice for discouraging low bidding trend. The expected outcome was assumed to be applicable for policy making in concerned authority.

Abstract :

Misconduct and crime of all sorts are the popular problems that bother humanity in general. This research work seeks to review and suggest the best solution to this problem. From this study, it was noticed that most research carried out has been focused on monitoring, controlling, and tracking automobile crimes, a process that has become difficult as in producing good results to adequately combat these crimes. Monitoring, tracking, and/or controlling automobile crimes are not most reliable due to certain conditions such as atmospheric or weather conditions, lack of knowledge, etc. So, with this challenge, this study reviews and suggest a better solution to this problem. If implemented, the suggested solution will help reduce the rate of automobile crimes by providing relevant authorities with good predicted results as information for battling automobile crime effectively. The suggested solution involves implementing a model using a good and best dataset alongside the best deep-learning algorithm. Finding shows that deep-learning algorithm provides successful, general, accurate, and fast result analysis. The obtained dataset should be filtered for noise and other unwanted values to ensure accuracy, reduce computation time, and provide an adequate understanding of the solution.

Abstract :

In the current globalised and severely competitive market, industrial firms are continuously striving for enhancing their productivities. For improving economic performance of firms, the study of relationship between input and output variables in production is inevitable. In the nineteenth and first half of twentieth century there was not much interest among firm management executives in production function analysis due to surplus availability of raw materials and conventional manufacturing practices. But in the contemporary world there is more number of products, companies, and increased competitive market scenario compelling quality products, cost effective production and efficient utilisation of raw material and energy resources. To obtain a comprehensive and clear picture of expenditure involved and profits earned through production in an industry, the analysis of various factors of production is essential. In this backdrop, this paper presents an empirical study carried out across 40 firms of a rice-mill industry cluster of Koppal in Karnataka state. Employing the empirical data obtained through researcher administered questionnaire, the relationship between various production inputs and output was modelled using Cobb Douglas production function. The assumptions in the Multiple Regression Analysis (MRA) adopted in this model are duly tested using SPSS software. The results of MRA revealed that the capital and energy inputs are significant while labour costs have insignificant influence with respect to the output. This finding establishes the need to focus on capital and energy inputs by this industry for enhancing their productivity leading to survival and growth in the long run.

Abstract :

The developed and developing countries in the world currently facing many challenges put forth by rapid growing population and in satisfying its needs. Though technology is progressing in hand with evolving industrial requirements, still industries are failing in conserving the biosphere. Globally the India has stood fourth in GHG emissions with 1725.76 million metric tons, 1.45 per capita CO2 emissions during year 2011. In India electricity generation, Manufacturing and construction, transportation and agriculture are the major sectors, which contribute for the net annual GHG emissions. Approaching towards food processing industries, the rice mills are found to have appreciable share in Industrial GHG emissions inventory. Present work gives the estimation of GHG emissions from chosen 40 rice mills of Koppal cluster per standard working month. The energy consumption data is collected through questionnaire based survey. The GHG emissions estimation is made using tier 1 and tier 2 approaches as per revised 1994 IPCC guidelines.

Abstract :

Composites have been widely used in engineering research since the increased interest in fibers and resins. This paper describes a polymer matrix that is supported by a low-cost plantain fiber-welding face shield system and thermal-structural analysis. A manual scraper process was used to extract the fibers from the plantain pseudostem and the hand lay-up molding process was used. Polyesters and resins have been successfully processed without heat or pressure to cure, so no heat has been released. Ansys 14.0 software tool was used to examine the thermal and structurally developed welding face shield. The welding face shield was developed, and the polymer matrix bonding between the fibers was found to be excellent and showed no signs of delamination or debonding. The findings of the analysis indicate that the average temperature distribution is within the correct range at a radiative temperature of 80 oC. The maximum total heat flux distribution of 25236 W/m2 has a minimal effect which shows that the insulation properties of the composite do not allow the effects of the welding temperature to penetrate the material and thus protect the user's face from the heat. The results of the stress analysis show that the maximum von misses stress distribution of 1.551E5 Pa is lower than the maximum main stress distribution of 1.8551E5 Pa at a radiative temperature of 80 oC, which means that the force is suitable for working conditions. The maximum total deformation of 4.1104E-5 m at a radiative temperature of 80 oC suggests that its strength is sufficiently high to withstand the stress factor in the working condition based on the fiber effect because it is less than the maximum directional deformation of 4.3862E-5 m. The composite welding face shield made from plantain fiber has a lighter weight compared to traditional materials and is durable and suitable for welding processes.

Abstract :

Nardostachys jatamansi DC and Chlorophytum borivilianum are listed as critically endangered under criteria A2cd in the International Union of Conservation of Nature’s (IUCN) Red List of Threatened Species. The multi therapeutic and nutritional importance of these species is attributed to the source of phytochemicals. The selected plant species for the study have been reported to be sedative, neurotoxic, cytotoxic, antidepressant, antioxidant, and antimicrobial. The total phenolic, flavonoid, flavonols, tannins, saponins and alkaloids of the selected plant species were analyzed. Nardostachys jatamansi DC had the highest phenolic, flavonoid, flavonols and tannins content in compare to other Chlorphytum borivilianum species. But the saponins and alkaloid content was found more in the Chlorophytum borivilianum (soil based) species than the other species. Nardostachys jatamansi DC had lower saponins and alkaloids content in compare to other Chlorophytum borivilianum species. It is advised that further research work should be carried out to isolate, purify, and characterize the bioactive compounds found in these critically endangered plant species.

Abstract :

The variation of asphalt binder content from that of the job mix formula usually influence the viscoelastic properties of asphalt concrete mixture. In the present investigation, asphalt concrete mixtures for wearing course are prepared at ± 0.5 % of the optimum binder content. Asphalt concrete slab samples were prepared using roller compaction. Beam specimens were obtained from the slab samples and tested for viscoelastic properties after practicing long term ageing and moisture damage. The phase angle, and cumulative dissipated energy as a major viscoelastic properties were evaluated with the aid of four-points bending beam test at 20 ºC environment and under constant microstrain level of 750. It was noticed that the specimens prepared with lower than optimum binder content exhibit the higher phase angle after practicing moisture damage or long term ageing. The phase angle decline to a range of (35-15) ° and (10-26) ° for moisture damaged mixture and long term aged mixture at 5.3 % binder content. The phase angle increases to an optimum value of (46 and 54) ° for mixtures prepared with (4.3 and 5.3) % binder respectively. It was concluded that the viscoelastic properties of asphalt concrete in terms of phase angle, and cumulative dissipated energy, are greatly sensitive to the variation in binder content. It was recommended that a stringent control of binder content should be implemented in the field to enhance the viscoelastic properties of asphalt concrete throughout its service life.

Abstract :

Games in the twenty-first century have the potential to be important educational tools. Today's kids are easily distracted, and game-based learning is the panacea because it has the potential to fully immerse them in the subject and curriculum. Not only can game-based learning bring a course to life by engaging and motivating students, but it may also serve as a platform for critical thinking, creativity, quick feedback, and collaboration. Different learning styles of pupils are one of the most difficult obstacles in education, yet game-based learning can easily overcome this. Different genres of games include action, adventure, fighting, puzzles, role-playing, simulation, sports, and strategy. Game designers may be able to choose the genre that is best suited for effective learning. Even with all the benefits of game-based learning, some obstacles remain, such as teachers' resistance to change or poor educational game design. Some teachers may be intimidated by students who are often far ahead of them in their use of technology. In this aspect, there is a significant conceptual generation gap, and planning, developing, and implementing games in curricula can be costly. While some games can be repurposed for educational purposes, many cannot be repurposed to satisfy student expectations. Because of the large appeal of games, many educators are introducing a wide variety of concepts through gaming. By teaching students through educational games, teachers can engage students, and students have fun while learning. However, from a large number of game engines and frameworks dedicated to educational game development, determining which tool to employ may be problematic. This literature review identifies the research on game development, the challenges from educators’ perspectives, and the possible technical barriers developers must overcome to develop truly engaging educational materials through gaming.

Abstract :

Recent studies in bio-informatics and bio-medical data include microarray technology to gain insight about organisms. While researchers still study on microarray data the real challenge remains as to interpret the huge dimensions that is the vast features with a very low sample space. This paper aims to reduce the enormous dimension of the microarray dataset using feature selection and classification methods. A variety of datasets with binary and multi-classes were taken for experimental analysis. Different classification algorithms were deployed to the reduced datasets and a high classification accuracy was achieved. In this paper, comparative study on classifiers using proper visualization tools have also been discussed.
