Perhaps, these are the places where you may get a valauble answer of such questions like yours:

Good luck

TRNSYS Error 118 typically indicates an issue with the input data or the simulation setup. Here are some steps you can take to resolve it:

1. **Check Input Data**: Verify that all input data files required for your simulation are correctly formatted and contain valid data. Pay special attention to any data files referenced in your TRNSYS project.

2. **Review Component Inputs**: Double-check the inputs and parameters for each component in your TRNSYS project. Ensure that all inputs are within valid ranges and that there are no conflicting settings.

3. **Inspect Connections**: Review the connections between components to ensure they are properly defined and compatible. Make sure that inputs and outputs are connected appropriately and that there are no missing or redundant connections.

4. **Validate Models**: Check the models used in your simulation for errors or inconsistencies. Ensure that any custom or user-defined models are correctly implemented and that they produce the expected results.

5. **Debugging Tools**: Use TRNSYS debugging tools, such as the TRNSED editor or TRACE mode, to identify the specific source of the error. These tools can help pinpoint the component or input causing the issue.

6. **Consult Documentation**: Refer to the TRNSYS documentation, including manuals, tutorials, and forums, for guidance on troubleshooting Error 118 and resolving common simulation problems.

7. **Contact Support**: If you're unable to resolve the error on your own, consider reaching out to the TRNSYS support team or community for assistance. Provide detailed information about your simulation setup and any error messages to facilitate troubleshooting.

By following these steps and systematically diagnosing the problem, you can effectively address TRNSYS Error 118 and ensure the successful execution of your simulation.

Jarne De Vleeschauwer Unfortunately, during the geometry conversion, particularly at the edges where internal connectivity was established in your modeling, overlapping surfaces have been detected. This could lead to issues with the analysis. To resolve this, please remodel or simplify the geometry, particularly focusing on the areas highlighted in the attached mesh screenshots. While this mesh can technically be used, it's highly advisable to remove the unnecessary overlapping surfaces for optimal results. The ABAQUS algorithm may not interpret overlapping surfaces correctly, potentially leading to inaccurate analysis. If you encounter further difficulties after addressing the overlaps, please don't hesitate to reach out for assistance on my WhatsApp; Https://wa.me/+923440907874

I found an error in my proof.

Interesting and practical question Prof Guoyu Ren , in developing and rapidly

evolving economies such as India, this concern resonates deeply, particularly in regions undergoing dynamic land-use transformations, often under the aegis of initiatives like "Smart City" developments. In these scenarios, meteorological stations that have been consistently recording data (SAT) over extended periods encounter disruptions, potentially compromising the integrity and continuity of the data. This phenomenon necessitates rigorous methodologies to ensure data homogeneity and compensate for any anomalies introduced by such transitions.

In India, the central agency, the relocation of India Meteorological Department (IMD) is responsible for maintaining and managing weather stations and it is done with meticulous care to ensure the continuity and integrity of meteorological data. The India Meteorological Department (IMD) often applies data homogenization techniques to maintain data consistency post-relocation. The standard practice is when moving stations with similar climatic conditions to the original, and occasionally, both old and new stations operate simultaneously to gauge data variations. Additionally, any relocation or significant station event is thoroughly documented, and regular equipment maintenance and calibration are prioritized, ensuring optimal accuracy in readings. But even after all these measures, it is highly unlikely to have the data completely error-free.

My dear, it is possible if all conditions are met .... Greetings

Yes you can on Design of Experment

Okay, I'm getting somewhere, and this (https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM144001) helps. So, judging by the looks of the descriptions offered, I guess I need LOG_RAT2N_MEAN or RAT2N_MEAN.

The question of whether your original set of scales form a more limited number of factors depends on the correlations among those scales. I suggest you form each of the scales and then examine the correlation matrix among them. If some of them are indeed high (say .8 or above), then it would make more sense to combine them rather than deal with the problem of multicollinearity that would result from trying to separate their effects.

I am aware of research on the relationship of mathematics skills and musical ability. That may give you a start. see the link:

Dear Almeshal ,

I just now realized that this questions is 4 year old, sorry

They are not good at measuring critical thinking and higher-order skills.

Dear Cristiane Tuma Santos,

Look the link, maybe useful.

Dear Williams,

The inverse relationship between a given sector (education, health, ...) is not uncommon. Budget is one thing, but not everything. There are a lot of factors that need be controlled (modeled in the functional relationship between quality of education and budget). One of the factor is budget allocation efficiency or budget alignment. Budget have to be spent where it can bring high impact, such as hiring, retaining and motivating teachers. The second factor is the quality and relevance of the existing curriculum at all levels. The third and most important issue is the role of parents in the day to day follow-up of their offspring: checking how their kids are performing in their exams, communicating with the school administration and proper understanding of their children's aptitude and inclination. The last point is the school environment has to be safe, attractive and motivating for the kids to pursue their education. In conclusion, unless we understand the state of the above factors and how their interacting with the educational system of the country, we cannot have a clear picture, what would have happened without the big money flow into the sector?

I would check the imported geometry. It's possible that Solid Edge created properties (e.g. segmented curves) so that the imported and CST structures are not identical. Don't judge sameness based on the rendering of the models in GUI. Plot and compare the actual mesh. Look for differences, particularly in how curved surfaces or sharp discontinuities are meshed.

The US Air Force sends UAV data via satellite all the time.  Also flight control can be done via satellite when latency is not a problem.  Takeoff and landing are always done via line of sight radio.  USAF uses the term remote piloted aircraft, so try a search for RPA instead of UAV. 

Thank you for your help Mohamed-Mourad Lafifi 

You could use BDDs and explore all paths to leaves. Structurally, some variables will be skipped in those paths so you would have to complement each path with the 2^n assignments to the n non-assigned variables along each such path.

Or take any SAT solver, find a satisfying assignment. Since SAT solvers assign every variable, it is a total assignment. Then adds the negation of this assignment (which happens to be a clause) to the original problem and repeat. The enumeration stops when there is no satisfying assignment. It is a bit of work, but I suppose this should be doable in a couple of hours.

You can use the bispectrum of your time series.

Hi Rosemary,

Thanks for your input. I hadn't considered that. I am imagining a scenario where cold agglutinins (or other proteins that can agglutinate) form clumps that the Ab gets trapped or non-specifically bound to, and then when one exposed Ag binding site binds to the plate there are lots of antibodies gunked together and so I detect more antibodies and the titre is higher. We'll try a different freeze down and if it looks funny on thawing maybe a high speed spin.

Please go through the following link for further details of simulation

did you solve this problem?  I'm facing the same problem.

there are many gram negative bacteria cross reacted with brucella such as yersinia, e.coli , salmonella enteritica, ochrobactrum but I had never read about cross reaction with mycobacteria. may be the patient has mixed infection. What about PCR because some time amount of bacteria in samples have little bacteria that cannot grow in media but give positive with PCR

OK - I understand. The criterion can be established by people who are experts (among other things).

Yes, that is a good idea. I've done a little of that, but I should definitely do some more speaking with experts. Thank you!

This problem is also referred as "all-SAT" (https://www.researchgate.net/publication/220884370_Memory_Efficient_All-Solutions_SAT_Solver_and_Its_Application_for_Reachability_Analysis). Indeed, classical algorithms just uses incremental SAT-calls, excluding the found solutions (cubes) as described in the link. These algorithms also try to minimize these cubes such that not the complete solution has to be excluded (see referred work).

There is some recent work (2014) on this issue. Unfortunately there exist only non-public minisat-extensions. But you may ask the authors of http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=6733111&queryText%3Dall-sat
