Refuse Derived Fuel (RDF) is excellent process to reuse the wastes from human activities or residual waste becomes renewable energy and also cut off the wastes volumes prior to transporting to landfill, it is an apart of supporting climate change mitigation due to waste generation and green house affect. This study is to focus on: 1. study on ratio of the waste material component to produce the RDF and, 2. testing and find out the RDF properties and calorific value of each material component. Therefore, according to the experiments found that, the mixtures of the plastics and dry leaves, plastics and papers, papers and dry leaves and plastics, papers and dry leaves indicated the calorific value are 14.91( ), 14.11( ), 15.02( ), 14.91( ) and 15.39 ( ), respectively.

This study aims to analyze and predict the number of Elementary School Students using Autoregressive Integrated Moving Average (ARIMA) method using data from the last 17 years, case studies in three provinces namely Bali, West Nusa Tenggara (NTB), and East Nusa Tenggara (NTT). This type of research is quantitative by comparing the final value on the first graph to the fourth graph to analyze on the graph what the predictive value is most accurate. Based on the results of the simulation of the number of elementary school students in Bali, NTB, and NTT provinces using the G-MFS application program and mathematical model calculations that the predicted results in 2021 on the data of the number of elementary school students in Bali province amounted to 417,805.40 with a percentage decrease of 0.1%, then the predicted result in the data of the number of elementary school students in NTB province of 512,381.76 with a percentage increase of 1.0%. The predicted result on the data of the number of elementary school students in NTT province amounted to 705,335.11 with an increase of 1.0%. The results of the forecasting of the number of elementary school students are expected to provide important information for the government to improve development in the education sector, especially at the elementary school education level in one way that is to improve the quality of educational infrastructure and many more developments that need to be done by the number of students in the future.

Geographical Information System (GIS) is an excellent tool to be employed with computer control system and play very significant role for database management, storing, capture, mapping and data analysis which includes vector and raster data. This study is mainly to focus on: (i) to study on the tree volumes, carbon storages and analyze the adsorption of carbon dioxide (CO2), (ii) to estimate the existing biomass within the reservoir and (iii) to create the spatial biomass distribution maps. Consequently, the distribution maps are described and indicated in low to high biomass density within the study area. Hence, this study has found that: there are 10,365.3 m3 of the total volume, 421.423 kg of total Carbone storage, 1,542.41 kg of total CO2 absorption and 36,346.48 tons of total Biomass within the study area.

The research work explores blood flow into a stenosed artery, or one with abnormal growth within it. At the throats and at the critical height of the stenosis, mathematical and computational models have been developed to calculate the various associated parameters such as flow rate, pressure gradient, impedance, and wall shear stress. Modeling blood as a power law fluid showed the dependency of these quantities on temporal and spatial variables, as well as the frequency of the flow oscillation in time and the key parameters of the flow mechanism. The exponential curve is the geometry of the stenosis studied in this analysis. Analytical expressions for axial velocity, volumetric flow rate, pressure gradient, blood flow resistance, and shear stress have been computed and simulated in ANSYS to generate useful results with respect to variation of flow parameters with power law indices and also for comparison between Newtonian and Non- Newtonian models of blood. Upon investigation, it was found that wall shear stress (WSS) increases with stenosis depth and therefore, plays a crucial role in affecting other flow parameters. At power law index 0.6, the highest shear stress and flow velocity were encountered at approximately 7 Pa and 0.5 m/s respectively.

We have reviewed the proof[1] of a conjecture posted in the Online Encyclopedia of Integer Sequences (OEIS)[2], which states that there are exactly five positive integers that can be represented in more than one way as the sum of non-negative integral powers of 2 and 3. The case for both powers being positive follows from a theorem of Bennett. We have also devised alternative logics to the elementary methods applied in the original paper “On duplicate representations as 2x+3y for nonnegative integers x and y”[1] to prove the case where zero exponents are allowed. Besides, we have included a nominal program towards the end, that verifies the statement of the conjecture.

The cause, effect and remedial measures of head injury is presented in a capsule form. The position of Brain is in the central location of the cranium and is well protected by nature with some layers surrounding it. Brain is the controlling organ of the human body, so its damage or even injury has gained attention among the scientists and physicians. As nobody will allow his/her head for investigation so modelling is a must for study of brain injury problems. The analytical study may give some idea on the location and degree of brain injury.

We have stepped into a world of undeniable data breach fatigues. Thus to ensure data security, encryption schemes come into action, one such highly talked about encryption nowadays is “Homomorphic Encryption” which is mainly used to compress data for their easy storage involving secure transmission and processing on cloud without compromising on privacy since special keys are needed for primary encryption and final decryption. Homomorphic encryption allows operation on two ciphertexts to give an encrypted (coded) result which when decrypted (decoded) maps to result of the operation, if it would have been on plaintext. It can be either multiplicative like the RSA or additive like the Pallier cryptosystem. Here we also focused on ideal lattice based public key encryption scheme which is almost bootstrappable. Multihop homomorphic encryption also has vital roles to play here. A strong homomorphic encryption is one which is resistant to all attacks using various algorithms. Thus our main objective is to allow encrypted computing on data, minimize memory usage and to save energy and time. Our presentation will try to focus on the researches done so far and also on the success rates of the scheme which is affecting the real world.

Mental health contributes significantly to people’s capacity to uphold good physical health – mental illnesses, for instance, anxiety and depression the ability for people to engage in health-supporting manners. In the human services field, mental health embraces the interpersonal group experience and personal experience. Mental health refers to a condition of effective functioning of psychological purpose leading in productive activities, the ability to adjust to change and put up with challenges, and satisfying relations with people. Mental health is vital to interpersonal and family relationships, personal development, and the capacity to contribute to society.
