In the theory of complex systems, a function tree is a diagram showing the dependencies between the functions of a system. It breaks a problem (or its solution) down into simpler parts, allowing the design and development to be more focused and efficient. [1]
When used in computer programming, a function tree visualizes which function calls another.
Control theory is a field of control engineering and applied mathematics that deals with the control of dynamical systems in engineered processes and machines. The objective is to develop a model or algorithm governing the application of system inputs to drive the system to a desired state, while minimizing any delay, overshoot, or steady-state error and ensuring a level of control stability; often with the aim to achieve a degree of optimality.
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines. The control systems are designed via control engineering process.
The Duke of Spoleto was the ruler of Spoleto and most of central Italy outside the Papal States during the Early and High Middle Ages. The first dukes were appointed by the Lombard king, but they were independent in practice. The Carolingian conquerors of the Lombards continued to appoint dukes, as did their successors the Holy Roman Emperors. In the 12th century, the dukes of Spoleto were the most important imperial vassals in Italy. From 1198, the Duchy became under the sovereignty of the States of the Church.
Hugh or Hugo (802–844) was the illegitimate son of Charlemagne and his concubine Regina, with whom he had one other son: Bishop Drogo of Metz (801–855). Along with Drogo and his illegitimate half-brother Theodoric, Hugh was tonsured and sent from the palace of Aachen to a monastery in 818 by his father's successor, Louis the Pious, following the revolt of King Bernard of Italy. Hugh rose to become abbot of several abbacies: Saint-Quentin (822/23), Lobbes (836), and Saint-Bertin (836). In 834, he was made imperial archchancellor by his half-brother.

Lambert I was the Count of Nantes and Prefect of the Breton March between 818 and 831 and Duke of Spoleto between 834 and 836. Lambert succeeded his father Guy.
Diarmaid of Armagh was Bishop of Armagh. He was made Bishop of Armagh in 834, but was driven from his see by the usurper Foraunan in 835. However, he claimed his rights and collected his cess in Connacht, in 836. He lived in a stormy age, as the Scandinavian rovers under Turgesius seized Armagh in 841 and leveled the churches. The Annals of Ulster describe him as one of "the wisest of the doctors of Europe". He is also known as Saint Dermot, and his feast is celebrated on 24 April.
The Heian Palace was the original imperial palace of Heian-kyō, then the capital of Japan. Both the palace and the city were constructed in the late 700s and were patterned on Chinese models and designs. The palace served as the imperial residence and the administrative centre for most of the Heian period (794–1185).
