Innovation has been a key element for huge successful firms in the past few decades. The fast pace at which the markets and market expectations change today requires firms to be able to come up with new ideas, products, and even manufacturing processes, which have never been seen before. Thus, innovation is one of the major elements in keeping our economy constantly growing. Throughout this paper we will present some of the basic models of innovation, starting with the definition of innovation itself. What does it mean? Where does it originate from?

This paper discusses a heat pump subsystem within an existing high-temperature DH system located at a railway station in Omsk, Russia. The goal is to increase the efficiency of an existing high-temperature DH system by describing decentralized heat generation from an environmental point of view. We obtain a balance method whereby the heat loss (or the thermal energy loss) is expressed dependent on the supply and return temperatures so as to reduce operating costs of heat supply. The outcome of calculating the heat loss by this method is a relation that is valid typically for all DH networks. Findings beneath show that switching to a low-temperature DH can decrease operating costs and increase overall heat production efficiency. The reason for the latter is a known logarithmic heat flux-temperature correlation. This paper concludes that the idea of decentralized generation has a great potential for the future, as the implementation of this concept is closely related to a low-temperature DH.

This paper discusses the design and the implementation of the wireless access network in residential complex with minimum access points. It has been investigated the power of transmitted signal and signal noise ration of the designed network. The experimental results show that the designed network has very good quality performance.
