The building sector consumes a large part of the energy used in the United States and is responsible for nearly 40of greenhouse gas emissions. It is therefore economically and environmentally important to reduce the building energy consumption to realize massive energy savings. In this paper, a method to control room temperature in buildings is proposed. The approach is based on a distributed parameter model represented by a three dimensional (3D) heat equation in a room with heater/cooler located at ceiling. The latter is resolved using finite element methods, and results in a model for room temperature with thousands of states. The latter is not amenable to control design. A reduced order model of only few states is then derived using Proper Orthogonal Decomposition (POD). A Linear Quadratic Regulator (LQR) is computed based on the reduced model, and applied to the full order model to control room temperature.

Cellulosic and woody biomass can be directly converted to hydrocarbon gasoline and diesel blending components through the use of integrated hydropyrolysis plus hydroconversion (IH2). The IH2 gasoline and diesel blending components are fully compatible with petroleum based gasoline and diesel, contain less than 1oxygen and have less than 1 total acid number (TAN). The IH2 gasoline is high quality and very close to a drop in fuel. The DOE funding enabled rapid development of the IH2 technology from initial proof-of-principle experiments through continuous testing in a 50 kg/day pilot plant. As part of this project, engineering work on IH2 has also been completed to design a 1 ton/day demonstration unit and a commercial-scale 2000 ton/day IH2 unit. These studies show when using IH2 technology, biomass can be converted directly to transportation quality fuel blending components for the same capital cost required for pyrolysis alone, and a fraction of the cost of pyrolysis plus upgrading of pyrolysis oil. Technoeconomic work for IH2 and lifecycle analysis (LCA) work has also been completed as part of this DOE study and shows IH2 technology can convert biomass to gasoline and diesel blending components for less than $2.00/gallon with greater than 90reduction in greenhouse gas emissions. As a result of the work completed in this DOE project, a joint development agreement was reached with CRI Catalyst Company to license the IH2 technology.

The current preferred method of making unitized aluminum aircraft structure is to machine it from a solid plate of material. This approach can be very wasteful in terms of material and energy, as much of the starting material is usually removed to create the final required part geometry. Nearer-net starting product forms, such as die forgings, require special dies, which have high costs, long lead times, and limited lifetimes. The forging process generally results in significant residual stresses in forgings, which can lead to production issues related to distortion when material is removed via machining to final part geometries. What is needed are ways to make tailored, near-net shape machining blanks, without expensive dies, and low residual stresses. A major objective of this project was to identify the energy benefits of combining a variety of solid state joining techniques, which are geometry independent, in order to produce high performance aluminum structures, while enabling the achievement of manufacturing benefits of lower-cost, faster cycle-time, and highly efficient joined structural assemblies. A further objective was to produce an energy consumption prediction model, which was capable of calculating the total energy consumption, solid waste burden, acidification potential, and CO2 burden in producing a starting product form, and then calculating the further energy consumption and environmental impacts of fabricating a final part configuration from the starting configuration. Yet another objective was to be able to utilize the model to compute and compare, on an individual part/geometry basis, multiple possible manufacturing pathways, to identify the best balance of energy consumption, environmental impact, and costs. Finally, another project goal was to help enable Solid State Joining (SSJ) technologies become better characterized, better utilized, and considered as mainstream processes, especially replacing/supplanting the energy intensive arc-welding/ fusion processes of joining such as gas-tungsten arc welding.

1～2月，我国电力设备制造业运行依然较为疲软：受国内经济增长势头趋缓影响，电力设备制造企业投资动力不足，行业固定资产投资增速较上年同期下降2.24个百分点；行业市场竞争依然激烈，大部分产品价格上升乏力，在中国机械工业联合会统计的电力设备制造业22个小类行业中，价格指数低于100的行业有18个，高于100的仅有4个。与此同时，大部分发电设备产量受上年同期基数较低影响，实现了较快增长，成为前两个月行业运行中难得的亮点。预计2014年1季度，电力设备制造业大部分主要产品产量将实现增长，行业出口形势将有所改善，但主要产品价格仍将低位徘徊，行业投资依然增长乏力。
