title: Benchmark instances for the preemptive single machine scheduling of equal-length jobs minimizing Total Weighted Tardiness

description: The benchmark is an attachment to the chapter "Preemptive Single Machine Scheduling: Theory and Algorithms" by Artem Fomin and Boris Goldengorin in "Handbook of Combinatorial Optimization" (https://doi.org/10.1007/978-1-4614-6624-6_109-1).

Our benchmark provides over a million 1|pmtn;pj=p;rj|∑wjTj problem instances. 
The instances' size is up to np=700, where n is the number of jobs and p is the common processing time with n in [10, 350] and p in [2, 20].
For each instance we provide the optimal objective function value, corresponding optimal schedule and time in which it was found by the algorithm described in the paper. 

The instances in this benchmark are the same as in our previous dataset for the Total Weighted Completion Time (TWCT) problem with due dates added. Some of the bigger instances are omitted, as they could not be solved by our model in time. The previous dataset is available at: https://data.mendeley.com/datasets/nrkx7467tf

For a more detailed dataset description, see the "readme_twt.txt" file. For an even more detailed description refer to the mentioned article.

For your convenience, we also provide a small version of the benchmark with only the first 100 instances for each problem size. It will be much easier to handle than the full dataset with more than a million instances, each in a separate file.

title: Data for Rheological and NMR Studies of Cellulose Dissolution in the Ionic Liquid BmimAc

description: Solutions of two types of cellulose in the ionic liquid 1-butyl-3-methyl-imidazolium acetate (BmimAc) have been analyzed using rheology and fast-field cycling (FFC) NMR spectroscopy, in order to analyze the macroscopic (bulk) and microscopic environments respectively. The degree of polymerization (DP) was observed to have a significant effect on both the overlap (c*) and entanglement (ce) concentrations, as well as the intrinsic viscosity ([η]). For microcrystalline cellulose (MCC)/BmimAc solutions, [η] = 116 mL g-1 which is comparable to MCC/1-ethyl-3-methyl-imidazolium acetate (EmimAc) solutions, whilst [η] = 350 mL g-1 for the commercial cellulose (higher DP). Self-diffusion coefficients (D) obtained via the model-independent approach were found to decrease with cellulose concentration and increase with temperature which can in part be explained by the changes in viscosity, however ion interactions on a local level are also important. Both Stokes-Einstein and Stokes-Einstein-Debye analysis were carried out to directly compare rheological and relaxometry analysis. It was found that polymer entanglements affect the microscopic environment to a much lesser extent than the macroscopic environment. Finally, the temperature dependencies of η, D and relaxation time (T1) could be well described by an Arrhenius relationship and thus activation energies (Ea) for flow, diffusion and relaxation were determined. We demonstrate that temperature and cellulose concentration have a different effect on short and long-range interactions.

title: Demand for metals in the energy and digital transition in Spain.

description: Excel file contains the exogenous parameters of the model: energy intensity of the technologies and sub-technologies, the Weibull functions of the life span of the technologies, the projected future installation of the technologies as well as the historical installation of the technologies, the collection rate for each technology and the recycling rate for the metals used in each technology. On the other hand, it contains several of the model outputs: the numbers of figures in the paper; the annual demand, end-of-life and recycled quantity of metals for each year of the study; the quantity of metals from primary extraction and recycling, as well as the annual recycling rate; and the environmental impact (measured in extracted rock, CO2 emissions and energy) of primary extraction of metals for each year.

Por otro lado, contiene varios de los resultados del modelo: los números de las figuras del artículo; la demanda anual, la cantidad que llega a su fin de vida y la cantidad reciclada de los metales para cada año del estudio; la cantidad metales procedentes de extracción primaria y de reciclado, así como el porcentaje de reciclado anual; y, el impacto (medido en roca extraída, emisiones de CO2 y energía) de la extracción primaria de los metales para cada año.
