Freins A L’Intégration Des Considérations Environnementales Dans Les Marches Publics De Travaux A Madagascar
Get PDFThe Public Procurement Code (PPC) of 2017 authorized the integration of environmental and social considerations in public procurement in Madagascar. However, this possibility of integrating sustainability criteria in public procurement is rarely used. Therefore, the study presented within the framework of this article aims to identify the main barriers that may hinder the effective implementation of the integration of environmental clauses and criteria in public procurement works in Madagascar, considering their strategic importance and their potential impacts on the environment. According to the results of the survey conducted out among public procurement professionals, organizational barriers linked to the lack of training and awareness are the most cited by respondents, followed by legal barriers such as the absence of a guide to sustainable public procurement as well as the inadequacy of the legal framework and standard documents, then economic barriers such as budgetary constraints, followed by political barriers, in particular the absence of a clear and defined policy. In addition to these main barriers, there are other barriers such as an overly financial vision focused on the lowest cost, difficulties in monitoring and control, time constraints, fear of contestations and appeals

Hybrid LSTM-RNN And Sarima Modeling For Time Series Temperature Prediction: The Case Of Antananarivo, Madagascar
Get PDFThis study evaluates various approaches for temperature forecasting in Antananarivo, Madagascar, by comparing the performance of LSTM and SARIMA models, as well as their hybrid combinations. One of the explored strategies involves using an LSTM model to generate an initial forecast, and then modeling its residuals with SARIMA to refine the results. Another approach relies on using SARIMA to produce a preliminary estimate, whose predictions are subsequently incorporated into an LSTM model to better capture the complex dynamics of temperature variations. The goal is to identify the method that offers the best accuracy and stability to improve the reliability of weather forecasts.While SARIMA has proven effective for linear data, it struggles to capture the non-linear fluctuations of local temperatures. The LSTM model, with its ability to model long-term dependencies and non-linearities, aims to address these limitations.Our study demonstrated that combining forecasting models, particularly the SARIMA_LSTM hybrid approach, offers superior accuracy compared to other models for temperature forecasting in Antananarivo. This approach, which integrates exogenous variables into the SARIMA model and uses LSTM to refine forecasts by modeling residuals, consistently produced the most accurate results.The performance of the models was rigorously evaluated using several statistical metrics and tests. We used the Root Mean Square Error (RMSE) to measure forecast accuracy, and Autocorrelation Function (ACF) and Partial Autocorrelation Function (PACF) plots to analyze the temporal structure of the data and residuals. Additionally, we applied the Ljung-Box test to verify the absence of residual autocorrelation, and analyzed skewness and kurtosis to understand the distribution of residuals. Finally, the heteroscedasticity test was performed to evaluate the constancy of error variance.These analyses confirmed that the SARIMA_LSTM model, by leveraging the strengths of each constituent model, successfully captured both seasonal trends and complex relationships in the temperature data, leading to more reliable forecasts

Extraction And Study Of Foam Glass From Volcanic Rock - Obsidian
Get PDFFoam Glass was obtained artificially almost a century ago and is still a widely used and it is a universal, environmentally and hygienically safe, lightweight thermal insulation material. Foam Glass, in addition to low thermal conductivity and moisture absorption, is non-flammable, resistant to water and chemical reagents, etc. This allows it to be widely used in construction, energy, chemical industry and other areas. Foam Glass is used to produce many types and areas of products - tiles and blocks, shaped thermal insulation, individual materials (grit, granules) and much more.The technology of manufacturing Foam Glass and Foam glass products is complex, as it requires a specific raw material base, as well as careful adherence to technological processes for the manufacture of porous glass and products from it.The economics of Foam glass making is largely determined by the availability and cost of raw materials, as well as costs incurred in obtaining charge. It becomes important to take into account issues such as the stability of the composition of raw materials and the minimization of the number and types of technological processes required for its preparation. In this regard, modern approaches to Foam Glass production are irrational.As an alternative raw material base for Foam Glass, we have chosen glass-obsidian of volcanic origin, mined in Georgia (Samtskhe-Javakheti region). Its deposit is a volcanic, entirely obsidian (glass) mountain, and its deposits were formed as a result of erosional processes, which are represented by a large number of detrital products.The results of the conducted research show that obsidian mono charge from the selected deposit can be used as a suitable raw material for Foam Glass production. Foam Glass is obtained by heat treatment of obsidian at a temperature of 1200± 20°C for 20-25 minutes, which ensures the production of a material with a bulk density of 180-200 kg/m3. Water absorption, sorption capacity, compressive strength and other properties of the resulting Foam glass fully comply with the requirements of the current glass standard
