+ * JOS-3 model simulates human thermal physiology including skin
+ * temperature, core temperature, sweating rate, etc. for the whole body and

+ * and was derived from 65 Multi-Node model (https://doi.org/10.1016/S0378-7788(02)00014-2)
+ * and JOS-2 model (https://doi.org/10.1016/j.buildenv.2013.04.013).
+ *
+ * To use this model, create an instance of the JOS3 class with optional body parameters
+ * such as body height, weight, age, sex, etc.
+ *
+ * Environmental conditions such as air temperature, mean radiant temperature, air velocity, etc.
+ * can be set using the setter methods. (ex. X.tdb, X.tr X.v)
+ * If you want to set the different conditions in each body part, set them
+ * as a 17 lengths of list, dictionary, or numpy array format.
+ *
+ * List or numpy array format input must be 17 lengths and means the order of "head", "neck", "chest",
+ * "back", "pelvis", "left_shoulder", "left_arm", "left_hand", "right_shoulder", "right_arm",
+ * "right_hand", "left_thigh", "left_leg", "left_foot", "right_thigh", "right_leg" and "right_foot".
+ *
+ * The model output includes local and mean skin temperature, local core temperature,
+ * local and mean skin wettedness, and heat loss from the skin etc.
+ * The model output can be accessed using "dict_results()" method and be converted to a csv file
+ * using "to_csv" method.
+ * Each output parameter also can be accessed using getter methods.
+ * (ex. X.t_skin, X.t_skin_mean, X.t_core)
+ *

+ * and JOS-2 model (https://doi.org/10.1016/j.buildenv.2013.04.013).
+ *
+ * To use this model, create an instance of the JOS3 class with optional body parameters
+ * such as body height, weight, age, sex, etc.
+ *
+ * Environmental conditions such as air temperature, mean radiant temperature, air velocity, etc.
+ * can be set using the setter methods. (ex. X.tdb, X.tr X.v)
+ * If you want to set the different conditions in each body part, set them
+ * as a 17 lengths of list, dictionary, or numpy array format.
+ *
+ * List or numpy array format input must be 17 lengths and means the order of "head", "neck", "chest",
+ * "back", "pelvis", "left_shoulder", "left_arm", "left_hand", "right_shoulder", "right_arm",
+ * "right_hand", "left_thigh", "left_leg", "left_foot", "right_thigh", "right_leg" and "right_foot".
+ *
+ * The model output includes local and mean skin temperature, local core temperature,
+ * local and mean skin wettedness, and heat loss from the skin etc.
+ * The model output can be accessed using "dict_results()" method and be converted to a csv file
+ * using "to_csv" method.
+ * Each output parameter also can be accessed using getter methods.
+ * (ex. X.t_skin, X.t_skin_mean, X.t_core)
+ *
+ * If you use this package, please cite us as follows and mention the version of pythermalcomfort used:

+ * and JOS-2 model (https://doi.org/10.1016/j.buildenv.2013.04.013).
+ *
+ * To use this model, create an instance of the JOS3 class with optional body parameters
+ * such as body height, weight, age, sex, etc.
+ *
+ * Environmental conditions such as air temperature, mean radiant temperature, air velocity, etc.
+ * can be set using the setter methods. (ex. X.tdb, X.tr X.v)
+ * If you want to set the different conditions in each body part, set them
+ * as a 17 lengths of list, dictionary, or numpy array format.
+ *
+ * List or numpy array format input must be 17 lengths and means the order of "head", "neck", "chest",
+ * "back", "pelvis", "left_shoulder", "left_arm", "left_hand", "right_shoulder", "right_arm",
+ * "right_hand", "left_thigh", "left_leg", "left_foot", "right_thigh", "right_leg" and "right_foot".
+ *
+ * The model output includes local and mean skin temperature, local core temperature,
+ * local and mean skin wettedness, and heat loss from the skin etc.
+ * The model output can be accessed using "dict_results()" method and be converted to a csv file
+ * using "to_csv" method.
+ * Each output parameter also can be accessed using getter methods.
+ * (ex. X.t_skin, X.t_skin_mean, X.t_core)
+ *

+ * JOS-3 model simulates human thermal physiology including skin
+ * temperature, core temperature, sweating rate, etc. for the whole body and
+ * 17 local body parts.
+ *
+ * This model was developed at Shin-ichi Tanabe Laboratory, Waseda University
+ * and was derived from 65 Multi-Node model (https://doi.org/10.1016/S0378-7788(02)00014-2)
+ * and JOS-2 model (https://doi.org/10.1016/j.buildenv.2013.04.013).
+ *
+ * To use this model, create an instance of the JOS3 class with optional body parameters
+ * such as body height, weight, age, sex, etc.
+ *
+ * Environmental conditions such as air temperature, mean radiant temperature, air velocity, etc.
+ * can be set using the setter methods. (ex. X.tdb, X.tr X.v)
+ * If you want to set the different conditions in each body part, set them
+ * as a 17 lengths of list, dictionary, or numpy array format.
+ *
+ * List or numpy array format input must be 17 lengths and means the order of "head", "neck", "chest",
+ * "back", "pelvis", "left_shoulder", "left_arm", "left_hand", "right_shoulder", "right_arm",
+ * "right_hand", "left_thigh", "left_leg", "left_foot", "right_thigh", "right_leg" and "right_foot".
+ *
+ * The model output includes local and mean skin temperature, local core temperature,
+ * local and mean skin wettedness, and heat loss from the skin etc.
