This study examines the use of sillimanite as a fine aggregate in the production of temperature-resistant reactive powder concrete. The impact of high temperatures on the mechanical strength of reactive powder concrete with High Alumina cement is investigated. The effectiveness of utilizing glass powder and sillimanite on the mechanical properties of RPC at high temperatures is investigated in this research. The samples were heated in the muffle furnace to the desired temperatures and then tested for their residual compressive strength, flexural strength and split tensile strength. The residual values of compressive strength, flexural strength and split tensile strength were measured at the temperature of 270C to 800°C. The weight loss of the specimens after exposure to the elevated temperatures was measured and the values showed enhanced resistance to the high temperature effects. The results demonstrate the greater contribution of glass powder and sillimanite towards the significant improvement of high temperature strength of reactive powder concrete than those made with normal quartz sand as fine aggregate.

To bring about innovation in the development of any product, it is required that the designer explores multitude design concepts right at the conceptual design phase of the product development cycle. At this phase, results of structural synthesis and analysis of mechanisms have been shown to serve as an invaluable tool in the attempt to infuse novelty in the design being conceptualized. There are several studies available in literature dealing with structural enumeration of kinematic chains. Invariably, all these studies culminate in reporting the results in an abstract form such as link adjacency matrix or its simpler variants like joints’ lists, etc. Certainly, it will be more useful to designers if the chain were reported in the pictorial form since it will be more intuitive for designers to fruitfully relate what is in his mind as an unformulated idea to what is directly visible as a sketch. This paper presents the results of a computer based method that converts link adjacency matrix into modified Franke’s notation format. The way to draw full-fledged chain from its modified Franke’s notation form is explained. Chains containing 8 or more links and possessing 1 to 5 freedoms have been sketched and made available in the form of a PDF file.

In equipment like high pressure vessels, there will caps on which loads of the order of several thousands of tons acts. Such caps require a huge number of big-diameter bolts, often M70 to M150mm in diameter. Each bolt will be subjected to a tremendous amount of force, on the order of 300 tons. The use of hand-operated wrenches to apply such a load is deemed out. When a high number of bolts are tightened on the flange, the applied load is lost owing to friction at the clamping surface and the applied load is not uniform. It is advised that a hydraulic bolt tensioning system be used to address these drawbacks. The device operates at a pressure of 1500 bar, which is extremely high. Therefore, the equipment must be designed to ensure the device’s compactness and safety. Bolt tensioners are used to tighten bolts and studs in a variety of important applications. These devices would be imported. It was proposed in this work that a small hydraulic bolt tensioner be designed and analysed using both theoretical and finite element analysis (Non-liner static analysis). The required boundary conditions and applied pressure were computed. The tensioner’s design was optimized to assure its safety and compactness.

All over the world desecration is a major factor for livelihood and plantation. There are various types of desecrations and major are air desecration ( or desecration), water desecration or water desecration, Industrial desecration, noise desecration, urban desecration etc. In India Act 1981 prescribes various functions for the Central Desecration Control Board (CPCB) at the open level and state desecration control board at the state level about air desecration. Act 1974 gives about water prevention and control desecration. Act 1986 section 2(a) explains noise desecration under rules, 2000. In this paper we are collected data of air pollutants such as particulate matter of 2.5 microns or less. particulate matter of 10 microns or less, Nitrogen Monoxide, Nitrogen dioxide, chemical compound of oxygen and nitrogen, Azane or Ammonia, Carbon Monoxide, Sulfur dioxide Ozone,Benzene, Toluene, Xylene, AQI, AQI_Bucket. For these variables we are fitted Machine Learning models such as Naive Bayes Classifier, CV Parameter Selection, K-nearest neighbours, J48 and Hyper Pipes using WEKA software. Detailed accuracy for models like TP ratio, FP ratio, precision, F-measure, ROC area are estimated. Using Root average square error, Average absolute error, we examine which is the best model.

Inventory control and management is an important task for every organization, wherein they need to determine the order quantity and order period to maintain enough inventory to meet the demand. The original Economic Order Quantity (EOQ) model was developed by Ford W. Harris to address this problem and determine the optimal order quantity that helps in optimizing the cost incurred by the organization. Even though this model gives a very good approximation on these parameters, there were many inherent restrictions to the model that were based on un-realistic expectations. In over a century since its original publication, many researchers have made extensions to this model to address the limitations and align it with real world scenarios. In this review paper, we intend to provide a representation of the original EOQ model, its limitations and the various extensions made to the model to address these limitations.

The experimental work on characterization of biochar bricks as a construction material is summarized in this manuscript. This is an important topic to research due to the dearth of knowledge about biochar construction materials and their potential to reduce global warming. Biochar is a charcoal-like substance formed from organic matter decomposition in the absence of oxygen at high temperatures. The use of bio char in a range of applications will help in cutting down CO2 emissions, recycling of organic and plastic waste, and in creation of more jobs. Current applications of bio-char is limited to being used as Soil additives to promote water absorption, plaster to absorb humidity, and energy alternatives to replace fossil fuels. The present study attempts to characterize bio-char bricks for usage in construction. Two types of bio-char bricks were cast and compared to normal concrete bricks. The first set of bricks had 70% biochar and 30% cement, whereas the second set contained 45 percent biochar, 45 percent plastic, and 10% cement. The bricks were characterized using five tests: compressive strength, water absorption, hardness, flammability, and insulation value.
