The article presents experimental studies of typical Finnish highly insulated (HI) envelopes with thermal resistance values ( R value) for the wall and roof inside ventilation cavity between 7.7 8.1 m 2 K/W 13 K/W, respectively. conditions in cavities were studied by using increased exterior part cavity, which 0.18 1.57 walls, 0.13 2.13 roof. With higher temperature only after closing inlet gap...

The concept of ‘effective’ thermal resistance could facilitate in-depth understanding the impact passive substrate properties such as surface radiative and thermo-physical (which are not directly measurable using instrumentations in terms R-value). A simple to-use concise single performance factor has been formulated this study to comprehend effective provided by enhanced envelope materials. de...

To mitigate the urban heat island effect has become a global issue when we are faced with the challenge of climate change. Through literature review, plant photosynthesis can reduce the carbon dioxide and mitigate the urban heat island effect to a degree. Because there are not enough open space and parks, green roof has become an important policy in Taiwan. We selected elementary school buildin...

This study investigates people's preconceptions of green roofs and their visual preference for different green roof design alternatives in relation to behavioral, social and demographical variables. The investigation was performed as a visual preference study using digital images created to represent eight different alternatives: gravel roof, extensive green roof with Sedums not in flower, exte...

The selection and configuration of building materials for optimal energy efficiency in a building require some assumptions and models for the thermal behavior of the utilized materials. Although the models for many materials can be considered acceptable for simulation and calculation purposes, the work for modeling the real time behavior of phase change materials is still under development. The...

Key-insulated cryptography is an important technique to protect private keys in identitybased (IB) cryptosytems. Despite the flurry of recent results on IB key-insulated encryption (IBKIE) and signature (IBKIS), a problem regarding the security and efficiency of practicing IBKIE and IBKIS as a joint IB key-insulated signature/encryption scheme with a common set of parameters and keys remains op...

It is difficult to evaluate the sloshing load acting on a fixed roof of tank because it depends on the collision of the liquid to the roof. In this paper, the SPH simulation was introduced to evaluate the load acting on a fixed roof. The results obtained by the simulation showed good agreement with those obtained from other method. In addition, the effect of the roof-liquid clearance on the slo...

BACKGROUND AND OBJECTIVES Many studies have investigated the application of micro-insulated needles with radio frequency (RF) to treat acne in humans; however, the use of a micro-insulated needle RF applicator has not yet been studied in an animal model. The purpose of this study was to evaluate the effectiveness of a micro-insulated needle RF applicator in a rabbit ear acne (REA) model. STUD...

In key-insulated cryptography, there are many private keys with different indexes and a single, fixed public key. When the trust model includes multiple Certification Authorities (CAs), it can be used to shorten the verification path and mitigate the damage caused by the compromise of a CA’s private key. Existing work requires that the total number of CAs be fixed and that a trusted keystore st...

Exposure of secret keys may be the most devastating attack on a public key cryptographic scheme since such that security is entirely lost. The key-insulated security provides a promising approach to deal with this threat since it can effectively mitigate the damage caused by the secret key exposure. To eliminate the cumbersome certificate management in traditional PKIsupported key-insulated sig...
