recently, with increasing of interest of all people especially young people and teenagers to sports in iran in parallel the tendency of investors both in governmental and private parts is increased ,and in this part the special places and spaces of sport was not departed , and billion rials (iran’s currencies) is paid for making some places for sport or equipped the old building .in this part f...

A new method for the synthesis of an insulated π-conjugated monomer was developed via the sequential self-inclusion followed by the elongation of the π-conjugated unit. The monomer was utilized in the synthesis of stimuli-responsive insulated molecular wires.

3D city modelling is a rapidly growing research area in the field of feature extraction. As the demand for 3D data increases, so does the necessity for higher detail building models. The use of aerial imagery and photogrammetric processing has been dominant in the field of feature extraction for several decades. Recently this dominance has been challenged by laser scanning techniques which offe...

The composting of a faeces/ash mixture and food waste in relative proportions of 1:0, 1:1 and 1:3 was studied in three successive experiments conducted in Kampala, Uganda in 216 L reactors insulated with 75 mm styrofoam or not insulated. The faeces/ash mixture alone exceeded 50 degrees C for < or = 12 days in insulated reactors, but did not reach or maintain 50 degrees C in non-insulated reacto...

The need to prepare cities for climate change adaptation requests the urban modeller community to implement sustainable adaptation strategies within their models to be tested against specific city morphologies and scenarios. Greening city roofs is part of these strategies. In this context, the GREENROOF module for TEB (town energy balance) has been developed to model the interactions between bu...

To minimize the damage caused by key-exposure in ID-based signatures, in ISPEC’06 Zhou et al (2006) proposed an ID-based key-insulated signature (IBKIS) scheme. However, their scheme is not strong key-insulated, i.e, if a user’s helper is compromised, the adversary can derive all of this user’s secret keys for any time period. Moreover, in practice, to alleviate the damage in case of key-exposu...

Key insulation is an important technique to protect private keys. To deal with the signing key exposure problem in attribute-based signature systems, we propose an attribute-based threshold key-insulated signature (ABTKIS) scheme. It strengthens the security and flexibility of existing attribute-based key-insulated signature schemes. Our scheme is provably secure in the standard model (i.e. wit...
