Future home design: an emotional communication channel approach to smart space

Smart spaces use human–computer interfaces (HCIs) to improve how humans experience their surroundings. However, HCIs are sometimes less user-friendly and intuitive than their traditional counterparts. Our research aims to use every-day objects to create communication channels between spaces and people, which can then strengthen interpersonal emotional relationships through a natural and unobtrusive interface. This study explores how using simpler instruments such as a whiskey glass, a table, and an MP3 player to interact with a dwelling improves user experience in a HCI-equipped smart space. We implemented a real smart space—the Time Home Pub, which not only adjusts the environmental atmosphere (such as background lighting, music, and photos) in response to human activities but also encourages a better connection between humans, their memories, and physical space. Time Home Pub was exhibited at the Taipei Fine Arts Museum in 2007 for the topic of Architecture of Tomorrow. Preliminary evaluations by visitors demonstrate the satisfactory feasibility of the system and how a smart space could change and improve human experiences through the use of new technology and architectural design elements.     

Headquarter-centered common sourcing management through order coordination and consolidation

It is common for subsidiaries of a group company to use the same types of components for producing similar products. Different subsidiary companies may well procure such components from the same suppliers. This paper studies two sourcing management models. One is the Subsidiary-Autonomous Sourcing Management (SD-ASM) where subsidiaries manage their inventories and place purchasing orders independent of each other. The other is the Headquarter-centered Common Sourcing Management (HQ-CSM) where purchasing orders of subsidiaries are processed centrally through some kind of headquarter coordination. In the SD-ASM model, each subsidiary places replenishment orders at a time interval corresponding to their economic order quantity (EOQ). In the HQ-CSM model, two purchasing order management policies are examined. One is the Order Coordination policy in which common replenishment epochs or time periods are proposed by the headquarter and the subsidiaries are encouraged to coordinate the timing of their orders based on the common replenishment epochs. The other is the Order Consolidation policy in which the subsidiaries combine the quantity of their orders and the headquarter places a combined order with the supplier. In the Order Coordination policy, classic RAND heuristic is used to find the best common replenishment epoch and the best replenishment timing of each subsidiary. In the Order Consolidation policy, the optimal order quantity of the combined order is obtained from a mathematical model. The combined order is then allocated to the subsidiaries according to a proportional allocation rule. A series of numerical studies is conducted to compare the costs of the SD-ASM and HQ-CSM policies. The results show that HQ-CSM outperforms SD-ASM in terms of cost and robustness against demand uncertainties. This achievement is largely due to the economies of process (synergistic ordering process), the economies of scale (large order quantity with price discount) and risk pooling effect (transshipments). The results also reveal that the Order Consolidation policy with a combined order always performs better than the Order Coordination policy with common replenishment epochs especially in face of high demand uncertainties and high service level in the global market.     

Artistic preprocessing for painterly rendering and image stylization

A practical image enhancing technique is presented as a preprocessing step for painterly rendering and image stylization, which transforms the input image mimicking the vision of artists. The new method contains mainly two parts dealing with artistic enhancement and color adjustment, respectively. First, through feature extraction and simplification, an abstract shadow map is constructed for the input image, which is then taken as a guide for emphasizing the light–shadow contrast and the important shadow lines. Next, to simulate the intense color emotion often subjectively added by the artist, a color adjustment technique is proposed to generate lively colors with sharp contrast imitating the artistic vision. The preprocessing operation is compatible with existing stylization and stroke-based painterly rendering techniques, and it can also produce different types of stylization results independently.

Further result on a dynamic recurrent neural-network-based adaptive observer for a class of nonlinear systems

In Kim et al. [(1997) A dynamic recurrent neural-network-based adaptive observer for a class of nonlinear systems. Automatica 33(8), 1539–1543], authors present an excellent neural network (NN) observer for a class of nonlinear systems. However, the output error equation in their paper is strictly positive real (SPR) which is restrictive assumption for nonlinear systems. In this note, by introducing a vector b₀ and Lyapunov equation, the observer design is obtained without requiring the SPR condition. Thus, our observer can be applied to a wider class of systems.     

A hierarchical test methodology for systems on chip

We present a hierarchical test methodology for testing a SOC with heterogeneous cores, including the 1149.1-wrapped, P1500-wrapped, and BIST memory cores. We propose an 1149.1-based hierarchical test manager that also provides P1500 test control signals. This scheme includes a memory BIST interface, providing both serial and parallel access ports for BIST circuits. Our approach offers low area and pin overhead, and high flexibility     

树脂浸渍补充增密对C/C复合材料摩擦磨损性能的影响

将CVD预增密至不同初始密度的C／C复合材料进行树脂浸渍／炭化补充增密至1.85g/cm^3，热处理后进行热物理性能的检测和不同刹车压力的摩擦磨损试验。结果表明，树脂浸渍／炭化是一种行之有效的快速致密化手段，所得制品的可石墨化性较好，导热性能也满足国外同类产品的要求；摩擦磨损试验和扫描电镜（SEM）观察结果表明，低一压力下形成的磨屑粒度明显大于高压下的磨屑，因而低压下的摩擦数高于高刹车压力下的摩擦系数。低压下的树脂炭对摩擦磨损的影响相对较大。
