Apocalypse Now’s Nightmare

2025-05-06T13:24:22+01:00

The production of Apocalypse Now serves as a compelling case study in chaos management under extreme conditions. Confronted with a host of challenges—ranging from unpredictable weather and the health issues of cast members to financial and interpersonal tensions—Francis Ford Coppola’s project offers valuable insights. Risk management was crucial, particularly the creation of contingency plans to address unforeseen events like Martin Sheen’s heart attack and a series of destructive typhoons. Logistical flow management also faced significant obstacles, as filming occurred in a remote location with limited infrastructure. Finally, Coppola’s leadership under pressure, balancing crisis management, improvisation, and team motivation, underscores the importance of organizational agility. This research note provides an analysis of these challenges and highlights their relevance across various industries.

The Lipschitz K(t) – Function for the Initial Value Problem (i.v.p) of an Ordinary Differential Equation (o.d.e) in One Dimension

2025-04-28T19:36:41+01:00

An elaborate but brief proof of the existence and uniqueness of the solution of an i.v.p for an o.d.e. is given. Because in both proofs the same initial condition is used, a considerable simplification of the K(t) Lipschitz function takes place. If the solution of the o.d.e. is known then the maximum interval of existence of the o.d.e. can be found again.

Time Travels are Already Possible Nowadays

2025-04-26T17:55:01+01:00

The theme of time travels has now been successfully mastered mainly by science fiction writers. The official position of science on this problem is as follows: although the possibility of time travels by the laws of physics is not excluded – teleportation in quantum mechanics, “twin paradox” in the special theory of relativity, “mole burrows” in the general theory of relativity, etc. – it will not be possible to create a time machine either now or in the distant future. However, this article provides descriptions of time travel realisations that are already physically feasible on Earth now.

Implementation of the New Metric Procedure of Multidecisions Makers Choice for Use in Large-zcale Voting Cases

2025-04-25T00:19:28+01:00

The problem of aggregating group preferences into a collective or consensual preference has been tackled since the 18th century by Borda and Condorcet. Since then, several authors have proposed aggregation methods based on social choice theory and metric procedures. However, the use of these metric procedures in decision-making processes today is very limited, and this is explained by the fact that their algorithms recommend multiple complex computations if the number of decision-makers (voters) and the number of alternatives (candidates) is high. To facilitate and popularize the use of metric procedures, it is therefore necessary to equip them with tools or computer programs. It is in this context that we propose in this article a python implementation of the New metric procedure of multidecisions makers choice . In this way, we have been able to set up a program that perfectly integrates the NPMCD algorithm. It is proving to be very efficient, as it allows us to obtain results in a very short time.

Coldening the Climate Through Elimination of Crematory Systems and Crematory Matter: A Review of Activities and Benefits for Peaceful Return of Migrants in the Global South

2025-04-28T16:53:39+01:00

It has been proven that crematory matter and crematory systems warm up the climate due to diffraction of gamma rays through the domineering shuriken atoms within. This has been confirmed through the destruction of crematory satellites with lasers, sodium-mash and a newer technology involving water-sodium-mashing of crematory satellites. The effects are local around the area of targeting but strong, with a minus 2°C observed. Water-sodium-mashing of crematory individuals has also worked significantly. This has been observed through experiments in three areas, with a reduction of up to 6 °C with 5 water-sodium-mashing systems working in the same location.

Improvement of Multi-criteria Evaluation Tools by AHP-ELECTRE II Hybridization: Application to Drilling

2025-04-25T22:38:37+01:00

Elimination and Reality Choices (ELECTRE II) and Hierarchical Decision Process Analysis (HDPA) methods are widely used in decision support. Although they are effective in many cases, they are not without their limitations. The AHP method is sometimes considered to be compensatory. As for the ELECTRE II method, it lacks rigorous tools for setting the weights of the decision criteria. To overcome these limitations, we have developed a hybrid method, AHP-ELECTRE II, which combines these two approaches. This AHP-ELECTRE II hybrid combines the advantages of both methods. In this way, we have been able to put in place a procedure that allows criteria to be weighted appropriately using the technique of binary comparison between criteria in accordance with the requirements of the AHP method. This comparison is made by the decision-maker, enabling him to determine the relative weights of the criteria objectively. We then used the weights of the criteria obtained to aggregate performance using the ELECTRE II method. This enabled us to deal with the interactions between the criteria and to rank the alternatives according to how well they met the criteria defined. In our study, we applied this hybrid method to didactic problems, which enabled us to obtain satisfactory results by taking better account of the decision-maker's preferences. We used it to evaluate areas suitable for drilling, simultaneously taking into account indicators of accessibility, potential and exploitable water.The advantage of this hybrid approach is that it combines the analytical rigour of AHP with ELECTRE II's ability to handle interactions between criteria, providing a more complete method that is suited to complex multi-criteria decision support problems.

Potential of Rubber Wastewater and Paddy Field Mud as Bioelectricity Producers Using Single-Chamber Microbial Fuel Cell

2025-04-20T08:00:45+01:00

Rubber wastewater contains many organic compounds that can pollute the environment if directly released. Likewise, paddy field mud also contains many organic compounds that can be utilized with rubber wastewater as an electricity producer through the process of breaking down organic compounds by microorganisms to produce electrons using the microbial fuel cell method. Microbial fuel cell will generate electricity while reducing waste load. This study was conducted to determine the potential of rubber wastewater and paddy field mud in the production of electricity through the process of degradation of organic matter by microorganisms. The treatment was done by combining rubber wastewater and paddy field mud with the ratio of 1:1, 1:2, and 1:3. The results showed that the highest voltage production by rubber wastewater was 228.1 mV and by paddy field mud was 27.4 mV. In the treatment, the highest voltage was 75.3 mV at a ratio of 1:1. There was also a decrease in waste load in the form of COD, BOD, TAN, TSS, and pH. The isolation results on the MFC anode found 6 isolates, namely Citrobacter sp.1, Citrobacter sp.2, Citrobacter sp.3, Citrobacter sp.4, Clostridium sp., and Bacillus sp. It can be concluded in this research that rubber wastewater and paddy field mud have the potential to produce electrical energy through microbial fuel cell. It is hoped that optimization in further research on electricity production will be useful as an environmentally friendly renewable energy.
