Simultaneous acetone butanol ethanol (ABE) fermentation by Clostridium beijerinckii P260 and in situ product recovery was investigated using a vacuum process operated in two modes: continuous and intermittent. Integrated batch fermentations and ABE recovery were conducted at 37 °C using a 14-L bioreactor (7.0 L fermentation volume) containing initial substrate (glucose) concentration of 60 g/L....

Attribute-based encryption allow user to encrypt data using public-key then it decrypt data using private-key in the cloud. ABE provide the public-key one-to-many encryption. Access polices and user attributes are associated with private keys and ciphertexts. The drawbacks of the existing ABE schemes are that decryption involves expensive pairing operations, the number of such operations grows ...

Use of starch solution as feed for butanol bioconversion processes employing Clostridium beijerinckii BA101 may have added economic advantage over the use of glucose. Acetone butanol ethanol (ABE) was produced from 30 gL(-1) starch solution using a continuous process. The bioreactor was fed at a dilution rate of 0.02 h(-1) and starch solution/feed volume (3 L) was replaced every 72 h. The conti...

Distributed data sharing has became an increasing challenge in modern distributed systems like cloud computing and online social networks etc., due to its data sharing archetype. The implementation of accessing policies and maintaining the policy updates has become a challenging issue in our Data sharing archetypes. Cipher text policy attributebased encryption (CP-ABE) is appropriate a capable ...

Ciphertext Policy Attribute-Based Encryption (CPABE) has been proposed to implement the attribute-based access control model. In CP-ABE, data owners encrypt the data with a certain access policy such that only data users whose attributes satisfy the access policy could obtain the corresponding private decryption key from a trusted authority. Therefore, CP-ABE is considered as a promising fine-g...

In this paper, we propose new non-monotonic attribute-based encryption schemes with compact parameters. The first three schemes are key-policy attribute-based encryption (KP-ABE) and the fourth scheme is ciphertext-policy attribute-based encryption (CP-ABE) scheme. • Our first scheme has very compact ciphertexts. The ciphertext overhead only consists of two group elements and this is the shorte...

In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), a user’s decryption key is associated with attributes which in general are not related to the user’s identity, and the same set of attributes could be shared between multiple users. From the decryption key, if the user created a decryption blackbox for sale, this malicious user could be difficult to identify from the blackbox. Hence in p...

We present selected new results on strong interaction physics from the SLD experiment at the SLAC Linear Collider (SLC), symmetry tests of b bg vertex, the rate of secondary b b production via gluon splitting, the B hadron energy spectrum and rapidity correlations between identi ed charged hadrons. The parity violation in Z ! b bg decays is consistent with electroweak theory plus QCD. New tests...

We give a complete classification of free and non-free multiplicities on the A3 braid arrangement. Namely, we show that all free multiplicities on A3 fall into two families that have been identified by Abe-Terao-Wakefield (2007) and Abe-Nuida-Numata (2009). The main tool is a new homological obstruction to freeness derived via a connection to multivariate spline theory.

Vehicular Ad Hoc Network (VANET) is an important part of the modern intelligent transportation system, which can provide vehicle communication at a certain distance. More importantly, VANET route planning and autonomous driving for drivers by analyzing data. However, VANET’s data privacy security are huge challenge when serving drivers. In this paper, we propose data-sharing model (DSVN) that c...
