In men, a testicular infection, tumor or twisting of the left testicle commonly causes pain that radiates from the testicle into the left side of the abdomen and back. When to See Your Doctor. Call your doctor right away if you develop abdominal and back pain, especially if it doesn't go away in a few days or worsens.
Autonomous Control in Production Logistics. For production systems, different autonomous control methods have been developed. All of these methods aim at enabling parts in a production system to decide about possible alternative routes through a production system.
Production: the planned production design is captured and recorded. Annotations may be added to the production design plan in relation to media codes and conventions and any changes to the production design. Production may be a collaborative process involving a number of people with specific roles or it may be an individual process. Reflection and evaluation of the production can occur through written documentation, oral feedback and/ or visual feedback.
