Concerning the communication infrastructure pertinent construction guidelines, China South Power Grid (CSG) has clearly defined and detailed the data network equipment quality control, test and check. This paper proposes two indicators to monitor the power distribution automation in LTE private wireless network. The first one is the distribution online ratio (DoR), which evaluates the effect of distribution automation infrastructure construction. The second one is distribution tunnel integrity ratio (DiR), which reflects the availability of distribution automation communication tunnel. Furthermore, an indicator computing assistant (ICA) is developed to collect the data of two indicators transmitted by the large number of custom premise equipment (CPE) in LTE private wireless network in a computationally efficient way, which frees the conventionally demanding human and computing resources..

Copenhagen summit results could be called a failure. This is the failure of UN climate change policy management, but definitely the first step to a new order as well. The article reviews main characteristics of climate policy paradigm shifts. Russian interests in climate change policy and main threats are analyzed. Successful development and implementation of energy savings and energy efficiency policy are necessary and would sufficiently help solving the global climate change problem.

Pilot data indicate that wood chip pretreatment with oxalic acid reduced the specific energy required to make thermomechanical pulp. A combined oxalic acid/bisulfite treatment resulted in 21% refiner energy savings and 13% increase in brightness for aspen. A low level of oxalic acid treatment was effective for spruce. Energy savings of 30% was observed with no significant change in strength properties. Adding bisulfite did not significantly increase the brightness of the spruce pulp. For pine, the optimum treatment was a moderate level of oxalic acid, which resulted in 34% energy savings and an increase in strength properties. For all of these treatments 1–3 w/w % carbohydrates were recovered, which can be fermented to produce ethanol. The extract sugar solution contained significant quantities of arabinose.
