To gain an insight into the function of heat shock proteins (HSPs) in insects during thermal stress, three HSP cDNAs were identified in the transcriptome of adult Heortia vitessoides, one of the most destructive defoliating pests in Aquilaria sinensis (Loureiro) Sprenger forests. The open reading frames of HvHsp60, HvHsp70, and HvHsp90 were 1,719, 2,070, and 2,151 bp in length, respectively, and encoded proteins with molecular weights of 61.05, 75.02, and 82.23 kDa, respectively. Sequence analysis revealed that all three HSPs were highly conserved in structure. Regarding the stage-specific expression profiles, HvHsp60, HvHsp70, and HvHsp90 mRNAs were detected in all developmental stages. Regarding the tissue-specific expression profiles, the expression levels of the three HSP genes were different in various larval and adult tissues. Moreover, the expression patterns of heat-stressed larvae, pupae, and adults indicated that HvHsp60, HvHsp70, and HvHsp90 were heat-inducible. In particular, HvHsp60 transcripts increased dramatically in larvae and pupae that were heat-stressed at $40^{\circ}C$ and were upregulated in adults that were heat-stressed at $35^{\circ}C$ and $40^{\circ}C$. The expression of HvHsp70 significantly increased in all of the three different developmental stages at $35^{\circ}C$, $40^{\circ}C$, and $45^{\circ}C$. The expression of HvHsp90 obviously increased at $30^{\circ}C$, $35^{\circ}C$, and $40^{\circ}C$ in larvae and could be induced at $35^{\circ}C$ in pupae and adults. The results suggest that HSP60, HSP70, and HSP90 play a major role in protecting H. vitessoides against high-temperature stress.

This paper proposes a new bit-serial multiplier/divider architecture to reduce the hardware complexity significantly and to maintain the same number of cycles compared with existing architectures. Since the proposed bit-serial multiplier/divider architecture does not extend the number of bits in registers and an adde $r_tractor to calculate a partial product or a partial remainder, the hardware overhead can be greatly reduced. In addition, the proposed architecture can perform an additio $n_traction and a shift operation in parallel and the number of cycles for $\textit{N}$-bit multiplication and division for the proposed circuits is $\textit{N}$ and $\textit{N}$ + 2, repectively. Thus, the number of cycles for multiplication and division is the same compared with existing architectures. The SliM Image Processor employs the proposed multiplier/divider architecture and proves the performance of the proposed architecture.cture.

This paper proposes a new VLSI architecture for morphological filters and presents its chip design and implementation. The proposed architecture can significantly reduce hardware costs compared with existing architecture by using a feedback loop path to reuse partial results and a decoder/encoder pair to detect maximum/minimum values. In addition, the proposed architecture requires one common architecture for both diltion and erosion and fewer number of operations. Moreover, it can be easily extended for larger size morphologica operations. We developed VHDL (VHSIC hardware description language) models, performed logic synthesis using the SYNOPSYS CAD tool. We used the SOG (sea-of-gate) cell library and implemented the actual chip. The total number of gates is only 2,667 and the clock frequency is 30 MHz that meets real-time image processing requirements.

This work presents the design of a dual extended Kalman filter (EKF) as a state/parameter estimator suitable for adaptive state-of-charge (SoC) estimation of an automotive lithium-iron-phosphate ($LiFePO_4$) cell. The design of both estimators is based on an experimentally identified, lumped-parameter equivalent battery electrical circuit model. In the proposed estimation scheme, the parameter estimator has been used to adapt the SoC EKF-based estimator, which may be sensitive to nonlinear map errors of battery parameters. A suitable weighting scheme has also been proposed to achieve a smooth transition between the parameter estimator-based adaptation and internal model within the SoC estimator. The effectiveness of the proposed SoC and parameter estimators, as well as the combined dual estimator, has been verified through computer simulations on the developed battery model subject to New European Driving Cycle (NEDC) related operating regimes.

This paper is to show the meaningfulness of applying Information Technology Architecture (ITA) to the modeling of a nation-wide e-Business architecture framework. After reviewing various architecture frameworks we suggested a unique architecture framework called VMT (Views, Models, and Time-frames). VMT represents five views of e-Business stakeholders; six models of data, function, network, agent, event, and rule; and three timeframes of short-term, mid-term, and long-term. VMT is an extension and unification of popular frameworks including Zachman's framework that has international recognition and use, C4ISR architecture framework of US DoD's, and Federal Enterprise Architecture Framework (FEAF) of the US Federal Government's.

Network-on-chip (NoC) architecture provides a highper-formance communication infrastructure for system-on-chip designs. Circuit-switched networks guarantee transmission latency and throughput; hence, they are suitable for NoC architecture with real-time traffic. In this paper, we propose an efficient integrated scheme which automatically maps application tasks onto NoC tiles, establishes communication circuits, and allocates a proper bandwidth for each circuit. Simulation results show that the average waiting times of packets in a switch in $6{\times}6$6, $8{\times}8$, and $10{\times}10$ mesh NoC networks are 0.59, 0.62, and 0.61, respectively. The latency of circuits is significantly decreased. Furthermore, the buffer of a switch in NoC only needs to accommodate the data of one time slot. The cost of the switch in the circuit-switched network can be reduced using our scheme. Our design provides an effective solution for a critical step in NoC design.

The cooling effects of botanical garden in urban are was investigated at Sungkyunwan University Natural Science Campus and nearby urban area during summer (20/06/2008-30/08/2008). Temperature and humidity data were observed, downloaded and analyzed. After observation single-family residential area (TNH) showed the highest air temperature while botanical garden (ARB) did the lowest one. UHI intensity between TNH and ARB was derived and investigated. The average UHI intensity was $1.5^{\circ}C$ while maximum UHI intensity was recorded at 21 : 20 by $2.29^{\circ}C$, and minimum UHI intensity at 09 : 20 by $0.45^{\circ}C$. Overall the average air temperature of botanical garden was lower to surrounding urban area by $0.5-1.5^{\circ}C$. So it was found out the botanical garden contributes to the cooling effect of the surrounding area as an urban cooling island.

The low grade domestic kaoline, such as pink-C and white-D, was converted to metakaoline, which has pozzolanic reactivity by heat treatment in the temperature range of $600^{\circ}C$ to 100$0^{\circ}C$ for preparing the spacer. The spacer was used for supporting the reinforced steel rod during construction to improve the safety of architecture. Pink-C and white-D were completely dehydroxylated when burnt at 80$0^{\circ}C$ for 1 hour and converted to metakaoline. The compressive strengths of specimens added calcined pink-C were lower than those of press molding mortar products inspite of calcining conditions. When white-D with calcined 80$0^{\circ}C$ and 100$0^{\circ}C$ for 1 hour was mixed 30% in the weight ratio of cement, the specimens cured 28 days had 338 $kg/cm^2$ and 347 $kg/cm^2$ of compressive strengths, respectively.
