This is a survey data collected in two rounds from the Kilosa district in the Morogoro region located in Eastern Tanzania, which is among the six biggest maize producing regions in Tanzania. Maize is the main food and income generating crop in Kilosa. The district is characterised by a semi-humid tropical climate. Its mean annual rainfall ranges between 800mm and 1400mm. The district receives long-term rainfall from March to early June and ‘short rains’ from November to January. The district experiences a long dry season between June and October. The temperature ranges from 18 to 30 degrees centigrade, depending on the altitude. These conditions offer a typical climate for maize production and a suitable case study area. Although Kilosa district has two rainy seasons, the pattern and amount of rainfall allow for only one harvest of the main staples per cropping season.
The survey sample consisted of 420 households in 21 villages in the Kilosa district. The sampling process involved two steps of random selection. First, a list of villages in Kilosa district which met two criteria: (1) maize is the main crop produced by the villagers and (2) maize is the main staple food in the village was obtained; and 21 villages were selected from the list. Second, 20 maize farming households from the household roster in the village office were randomly selected.

This case represents part of the European high voltage transmission network. It contains 1,354 buses, 260 generators, 1,991 branches and it operates at 380kV and 220kV. The data stems from the Pan European Grid Advanced Simulation and State Estimation (PEGASE) project. The PEGASE original data was obtained from Matpower (Which is also included here). The case has been modified to incorporate an HVDC Link and a MTDC grid. Two files contain the modified data, one in excel and one in AIMMS.dat
This was a cross-sectional study made on a sample of 224 respondents, aged 18 - 67 years (M = 39.18, SD = 11.15). The other characteristics of the sample are presented in Appendix A. Data were collected through several online survey campaigns made on social media networks, in Romania. The subjects were told that their participation helps researchers to better understand the predictors of road accidents and received no financial compensation for their effort. In order to be eligible to participate in the study, participants had to own a valid driving license and regularly drive a vehicle.
Here are the data and the codes used in Hiramoto&Cline (2020). Imaris image data, Matlab code, and data in mat or fig (with metadata) files are provided. These Matlab codes require a statistic toolbox.
Experimental and numerical data of a AKW RWK-42L hydrocyclone. It includes granulometric and global efficiency, particle volume fraction, liquid ratio, and feed flow for several configurations of the equipment. It also includes a video from water-air transient simulation using Free Surface model to observe if the air-core is formed in this hydrocyclone. The video shows that an air-core is not formed, but a small amount of air is entrained from the overflow.
