Artificial Intelligence-Driven Prediction of Hotel Booking Demand for Revenue Optimization
type: item
description: The rising competitiveness in the hospitality industry requires proper and smart forecasting models to maximize the hotel booking demand and revenue management plans. The proposed study is a hybrid CNN-Bi-LSTM model to predict the canceling of hotel bookings based on the Kaggle hotel booking demand dataset. An organized preprocessing system adopted, such as the missing value imputation, the treatment of ADR outliers, the encoding of labels, feature engineering, correlation-based feature importance analysis and, to enhance the model's dependability and data quality, the class balancing performed using SMOTE. The architecture proposed combines Convolutional Neural Networks (CNN) to obtain meaningful feature representations and Bidirectional Long Short-Term Memory (Bi-LSTM) networks to learn temporal patterns of booking. The applied approach has proven to be effective based on the results of performance evaluation with the help of confusion matrix-based measures 98.95% accuracy (acc), 98.82% precision (prec), 99.91% recall (rec), and 98.90% F1-score (F1). A comparative analysis indicates that the hybrid CNN-Bi-LSTM is much better than the classical models, which include Decision Tree, Random Forest, and standalone XGBoost. The results affirm the soundness, generalization and applicability of the suggested framework regarding the intelligent hotel booking demand forecasting and decision-making

Typology of Housing and Household Energy Behaviors in Cameroon: Diagnosis for better Energy Efficiency
type: item
description: This research analyzes the determinants of domestic energy efficiency in Cameroon through a quantitative study of 333 households in Douala, Yaoundé, and Ngaoundéré. Using Chi-square χ^2independence tests, the study explores correlations between sociodemographic factors, housing characteristics, and installed energy capacity. Key Results include: Material Inertia: A strong geographical dependence exists between cities and construction materials p < 0.001. Adobe bricks with cement mortar, dominant in Ngaoundéré, offer under-exploited thermal efficiency potential compared to the cement-dominated metropolitan areas of Douala and Yaoundé. Generational Transition: Refrigeration equipment follows a life cycle, with a critical acquisition phase between ages 25 and 35, identifying this as the pivot segment for introducing high-performance technologies. The Performance Paradox: Analysis demonstrates that physical size and equipment type are not reliable indicators of installed power. Only the Energy Class (A+, A++) allows for a real and significant reduction in power demand < 50 kW. Information Deficit: A major obstacle was identified: 69% of users are unaware of their appliance's energy class, a technical ignorance that increases with the surface area of the dwelling.

Design and Modification of Thermoelectric Tube using Different Materials
type: item
description: By using thermoelectric generators it is possible to develop independent electric energy source in burning and heating systems – in households and industrial heating. With this energy source it is possible to provide with electricity systems appliances, lightening and other consumers. Potential placements for generators are on furnace walls, on flue way walls, on flue pipe walls after furnace. Generators can improve efficiency of combustion, because there is amount of waste heat that leaves through flue pipe in burning process. There are no boundaries for combining elements in system as just the space for their placement. As more elements are linked in chain, as much electric energy is produced. This is one of methods to develop a cogeneration process in domestic boiler house or industrial heating, or burning systems. In research thermoelectric element current, voltage, power and efficiency are defined in different temperature differences.

Water as a Refrigerant for Heat Pump Technology: A Review
type: item
description: Even though water (R718) is one of the oldest refrigerants, it is very difficult to use it in compression refrigeration cycle due to its low molecular mass, high boiling point, low specific cooling capacity and a relatively higher value of kinematic viscosity. This paper gives us a glimpse about one of the technique which can be used to use water in compression cycle and also compares its theoretical analysis with the conventional refrigerants already being used. This paper can study the effect on various parameters under similar operation conditions for the comparative study of water and other refrigerants.

A Review on Cryogenic Grinding
type: item
description: The paper aims in improvisation of the grinding process for elastic materials like rubber, plastic, composites, metals, waxes etc. Nowadays, we find a lot of wastage of these materials. Some of them like plastic, artificial rubber composites are very much harmful for our environment. This research will basically help in cautious use of the above mentioned pollutants. For example, Thermoplastics are difficult to grind small sized particle at ambient temperature because they are soften adhere in lumpy masses and clog screens. In cryogenic grinding when thermoplastic is chilled by dry ice, liquid carbon dioxide or liquid nitrogen they can be finally grounded to powder suitable for electrostatic spraying and other powder processes. Advantages of these processes are to increase productivity through optimized particle size, elimination of caking product within the mill, increases protection from the fire and product oxidation due to inert milling atmosphere..

Cryogenic system for High Temperature Superconducting Power Cable-A Review
type: item
description: Materials which shows superconductivity above liquid nitrogen temperature are known as high temperature superconductors. J.G. Bednorz and K.A. Mueller were awarded noble prize for discovering high temperature superconductors in 1987. Since last 3 decades there has been significant augmentation in the field of superconductivity. The primary advantage of HTS power cable over conventional cable is the ability to carry more power per circuit with lower energy cost per megawatt delivered. Power transmission is loosely defined as the transfer of electrical energy from source to a load over conductors that carry relatively large currents, while being maintained at large voltage. In order to achieve liquid nitrogen temperature, efficient cryogenic system is required. Hence, it is integrated with HTS power cables. Several HTS cables have been designed, developed and operated in various parts around the world. Most of them are used for experimentation purpose. Very few of them are used in electrical grids. Use of high temperature superconductivity in electrical grids will have a major positive impact on power system operation and control. HTS power cable is placed into heat-insulated pipe which is filled with cryogen. Circulation of cryogen removes heat seeping through the insulation. HTS power cables with different design considerations can be used for transmission of AC and DC.

Review on Effective Utilization of Electric Energy for Water Heating by Water Changing Property
type: item
description: Electricity is major parameter in our life which having wide application. By survey we use maximum electric energy for comfort life. In during various application of domestic we use hot water. To heat a water use various equipment which based on electric energy. In this experiment pH of water will be changes by using natural resources by observe what will be effect on heating purpose. Energy important and major source use in industries as well as Domestic purposes. This project will give one idea about how will improve efficiency and to save energy of heating coil which are used in industry and domestic for to heat water. We know that now days we concentrated on to saving energy because one day all natural energy sources will be end. So now we concentrate on saving energy in any field and to utilize energy so it span time will increase. In America they are used shell gases which are new technique but one day it will be vanish. If we survey in world there are so many energy required to produce electricity and every person used electric energy so we need highest energy efficiency equipment. In boiler there is convention and non -convention method also some time we used coal but with considering time is money so they change input from coal to electric energy. This experiment we get best utilization of nature resource for to save energy. There will be getting best method to reduce electric energy so whenever coil or electric furnace boiler used there will be water treated process will conduct. There is hypothesis is if change in pH of water due to that electricity required to heat water is also vary.

Review on Heat Transfer Enhancement of a Plate Fin Type Heat Exchanger by Different Shapes of Fins
type: item
description: Heat transfer enhancement techniques as passive, active or a combination of passive and active methods are commonly used in areas such as process industries, heating and cooling in evaporators, thermal power plants, air- conditioning equipment, refrigerators, radiators for space vehicles, automobiles (in tracked vehicle it plays very important roll), etc. Passive techniques, where inserts, extended surfaces like fins of various shapes and sizes are used in the flow passage to enhance the heat transfer rate, are benefited compared with active techniques, because the insert manufacturing process is easier and it can be easily applied in an existing heat exchanger. In design of compact heat exchangers, passive techniques can play an important role if a proper passive configuration/combinations can be selected according to the heat exchanger working condition (both flow and heat transfer conditions). Ribs, fins, dimples, Vortices etc., are the most commonly passive heat transfer enhancement devices. In this paper, major emphasis is given to work with different shapes of fins, and their arrangement because, these are found effective heat transfer enhancement tools.

Performance investigation of centrifugal pump by varying blade angles of the Impeller–A Review
type: item
description: Centrifugal pumps are probably among the most often used machinery in industrial facilities as well as in common life. Centrifugal pump is widely used as a universal machine, so improving hydrodynamic performances of the centrifugal pump is important for energy saving. With the development of computational fluid dynamics (CFD), numerical simulation has become the main method for performance prediction and structure design of the pump. The impeller is the most important part in a centrifugal pump since it is the place where the mechanical energy is converted into hydraulic energy. Hence the parameters related to the impeller are directly affecting the performance of the pump. One of them is the blade exit angle; if it is not correctly designed, it can negatively affect the head and the hydraulic efficiency of the pump. The previous research suggests that a larger blade angle is suitable. Also, exit blades angle variation contributes more in the performance.

Experimental Investigation of Solar Adsorption Refrigeration System using Activated Charcoal-Methanol Working Pair
type: item
description: The extensive effort has made to develop the intermittent solid adsorption system that promises good alternative for solar refrigeration. Most research methods have used activated carbon–methanol for working pairs, and this has been considered as the most suitable working pair for solar solid adsorption Refrigeration. Going through the existing literature, it is revealed that there are no investigations on the simultaneous use of water cooled condenser, bypass way for adsorption process. Many researchers studied on TIM (transparent insulation material) for increasing the efficiency of solar collector. But, in this study, it is analyzed the solar powered refrigerator using polycarbonate glass, water cooled condenser with natural conduction, bypass way for adsorption to enhance the performance of solar adsorption system. Using this cyclical process it is possible to obtained cooling temperature of 11˚C. For increasing the effectiveness of solar heating, polycarbonate glass is used to achieve generator temperature up to 114˚C. In this system two valves with provision for bypass is made for easy operation and maintaining the flow of methanol during day and night. The solar powered activated charcoal-methanol paired system gives the cooling temperature up to 11˚Cfor 6kg water and achieve system COP=0.02.

Geometry optimization of exhaust manifold using CFD
type: item
description: It is well known that a appropriately designed Exhaust manifold is important for the optimal performance of an IC engine. Though, the intake system is dominant on the cylinder filling process, the exhaust manifold has ability to influence the gas exchange process in various important aspects, like the piston work done during the exhaust stroke, the short-circuit of fresh charge from the intake into the exhaust. We know that if the back pressure of Exhaust gases is higher, it reduces efficiency of the engine. So aim should be to reduce the back pressure of the engine. Also amount of pressure drop is equal to back pressure. So ultimate goal is to reduce its pressure drop by changing its geometry, reducing friction in the manifold . In this paper only Geometry optimization is done. This paper presents 3-D simulation of Exhaust manifold of 4 cylinder, 4 Stroke, turbocharged diesel engine(4G11 Greaves Engine) of generator by using ANSYS-CFX code and results are discussed. A Steady state CFD simulations have been accomplished and experimental results are compared for validation. The CFD results gives an idea for changing its geometry.

Implementation of Bharat Stage VI norms for small and medium duty CI engines
type: item
description: The emissions from the internal combustion engine are a major threat to the environment and thus needs to be controlled and kept a close watch on. India has decided to jump directly to BS VI after BS IV leapfrogging BS V. This paper mentions a few methods by which the target can be achieved and newer and better methods to achieve BS VI target. The changes that can be made to meet the stringent norms are either in the engine architecture, air handling system, after-treatment devices etc. But a sure shot method for the conversion of existing engines is still not present and is a major gap in the study and requires immediate attention.

Effects of Splitter Blades on Centrifugal Pump Performance - A Review
type: item
description: In turbomachinery design like pumps and compressors impeller is a crucial part. Centrifugal pump design is well facilitated by the use of Computational Fluid Dynamics (CFD). Opportunities do exist to improve the pump performance. This improvement can be achieved by making geometrical changes in design of an impeller like blade inlet & outlet angles, impeller inlet & outlet diameter and number of blades. Increase in number of blades increases the head and in addition causes the efficiency to decrease. This decrease in efficiency is due to the blockage of the fluid due to reduced area and increased friction inside the casing. Addition of splitter blades decreases the clogging at impeller inlet resulting in increase in pump performance. In this paper overview of various works by previous researches & their finding about study of effect of splitter blades on the centrifugal pump performance are done. And it is observed that as the splitter blade length increases; the flow rate and power increases, the efficiency decreases as well as hydraulic performances are improved, pressure fluctuations are reduced, and operating range is extended.On the other hand, the additional splitter blades will have positive effect on the cavitation performance due to the changes at the impeller inlet channel.

Analysis of gas diffusion in closed space: A Review
type: item
description: The hydro-chloro-fluorocarbon (HCFC) and hydro- fluorocarbon (HFC) are common refrigerant used for room air conditioner (RAC). But these are restricted due to a serious environmental issues owing to the high global warming potential (GPW). The replacement with low-GPW refrigerant such as R1234yf, R1234ze, R290 and R32 can be possible. R290 (propane) has major environmental and thermo-physical properties. But it is a flammable substance, thereby posing additional risks. When refrigerant leak into space, it may ignite if the concentration is higher than low flammable limit (LFL), there is always a region where the refrigerant concentration is higher than the LFL because the refrigerant concentration is 100% near the outlet from the air conditioner. Thus, understanding the refrigerant diffusion phenomena of low-GWP refrigerants is important to acquiring sufficient information for developing safety standards to assess the risks of using these refrigerants. In this study, diffusion phenomena were analyzed when a refrigerant leaked slowly from a room air conditioner (RAC) into a closed space.

type: item
description: To increase the efficiency of the heat exchanger, the heat transfer enhancement techniques are utilized. This can be achieved once the heat transfer power of a given device is magnified or once the pressure losses generated by the device are reduced. Heat transfer enhancement is require to achieve a high heat transfer rate using minimum pumping power, to make the equipment compact, to minimize cost of energy and material, to get high heat transfer effectiveness, to increase efficiency etc. Condensers are primarily heat exchangers within which the refrigerant undergoes a phase transition which have various designs and come in many sizes. Shell and tube condenser is the most common type of condenser used in systems from 2 TR up to thousands of TR capacity. The Condensation of steam on single horizontal copper tube in a shell and tube condenser has been investigated using experimental and theoretical ways during this study. The outer surface of the tube was changed by brazing it with a copper wire lengthwise and helically to enhance the heat transfer constant. The result of varied the pitch of the helically brazed wire was studied with twenty five millimeter and thirty five millimeter pitch. Lengthwise Wire Brazed (LOWIB) and Helically Wire Brazed (HEWIB) Copper tubes with pitch twenty five millimeter and thirty five millimeter were found to extend the heat transfer constant by an element of about 1.5, 2 and 1.2 severally.

Comparison of Performance and Exhaust Emissions of Jatropha, Palm and Calophyllum Inophyllum Biodiesel: A Review
type: item
description: The world is facing serious issue of environmental pollution and warming. Also, crude oil can become rare and faces severe shortfall within the close to future. Hence, this offers rise to researchers to seek out different fuel sources as alternate energy sources. Biodiesel is the fuel that has been thought of the best substitution for petroleum-diesel fuel as a result of it may be employed in any diesel-engine without any need of modification. Biodiesel is that the renewable fuel and additionally it's having sensible exhaust emissions as compare to diesel. Jatropha biodiesel, palm biodiesel and Calophyllum Inophyllum biodiesel falls within standard quality limits, hence they may be used as the alternative to diesel oil. The performance and exhaust emissions of Jatropha, palm and Calophyllum Inophyllum biodiesel are reviewed in this paper. Among the numerous biofuels available, vegetable oil is foremost economical in case of farmland usage, potency and productivity as it is the crop having oil carrying tendency. The problem associated with edible-vegetable biodiesel is that there's competition among oil as source of fuel or food. This makes edible oil not a perfect feedstock for production of biodiesel. Hence, more consideration is towards different non- edible oils like Jatropha oil, Calophyllum Inophyllum oil. Calophyllum Inophyllum oil may be being thought of as a possible fuel by following transesterification. However in comparison with Jatropha and vegetable oil biodiesel productions, biodiesel from Calophyllum Inophyllum continues to be in an exceedingly analysis state. Hence, long analysis and experimental studies got to be dole out previously considering this oil primarily based biodiesel as an alternate fuel to crude diesel.
