An improved Clonal selection algorithm based Artificial Immune System (AIS) is given for solving Job Shop Scheduling Problem (JSSP). To reduce the optimal solution search space, a bio inspired positive selection principle is proposed to populate the initial antigen library. This proposed algorithm gives the better start up and faster converging towards the optimal solution for the given JSSP. The given algorithm has been simulated in Matlab tool and the results were compared with the Genetic Algorithm (GA) generated results for a well known bench marking problem. AIS produced optimal solution for more than 90% run which 15% produced by GA. ©2010 IEEE.

A phytoremediation study was carried out at 5 major lakes of Bangalore to ascertain the degree of heavy metal contamination. The study focused on assessment of heavy metal accumulation in three aquatic macrophytes used as biomonitors, in comparison with water and sediments (abiotic monitors) for phytoremediation. The aquatic plants (biomonitors) Hydrilla vertia'llata, Nelumbo nucifera, Eichhomia crassipes were analysed along with sediments and water for Cu, Co, Pb, Zn and Ni contamination in five lakes (Aggrahara, Arakere, Naganaikanakere, Amblipura and Hulimavu). The order of accumulation of heavy metals was observed, in general, was Hulimavu > Ambalipura > Naganaikanakere > Arakere >Aggrahara. Based on the concentration, the toxicity status observed in macrophytes was H. verticillata > N. nucífera > E. crassipes. The heavy metals are arranged in the following descending order: Cu > Zn > Pb > Co > NI in macrophytes; Zn > Cu > Ni > Pb > Co in water and Zn > Cu > NI > Co > Pb in sediments. The selected biotic species showed maximum absorption of copper and zinc in all the lakes.

Polypyrrole-polymannuronate (PPy-PM) composite films were studied by preparing the composites via in situ deposition techniques. These studies on the chemical interactions, structural morphology, and thermal properties of the films support the formation of PPy-PM composites, and suggest that the ratio of pyrrole to PM is tailored to optimize the potential crosslinking inside the composite. The room temperature current-voltage characteristics and the frequency-dependent AC conductivity of the PPy-PM composites were studied within the frequency range of 102 to 106 Hz. Based on the aforementioned properties, the synthesis of PPy-PM composite films may suggest the future development of biomimetic materials that can be used to create new multicomponent and multifunctional bionanocomposite materials. © 2009 Springer Science+Business Media B.V.

The asymmetric unit of the title compound, C15H 17NO2, contains two independent molecules in which the dihedral angles between the pyrrole and benzene rings are 42.43 (9) and 45.70 (9)°. In both molecules, the but-oxy chains are disordered over two sets of sites, with occupancy ratios of 0.701 (7):0.299 (7) and 0.869 (4):0.131 (4). Each molecule forms a dimer with an inversion-related molecule, through a pair of N - H⋯O hydrogen bonds. Weak C - H⋯O inter-actions link these dimers in the crystal structure. © Prakash et al. 2012.

Email service proves to be a convenient and powerful communication tool. As internet continues to grow, the type of information available to user has shifted from text only to multimedia enriched. Embedded text in multimedia content is one of the prevalent means for delivering messages to content viewers. With the increasing importance of emails and the incursions of internet marketers, spam has become a major problem and has given rise to unwanted mails. Spammers are continuously adopting new techniques to evade detection. Image spam is one such technique where in embedded text within images carries the main information of the spam message instead of text based spam. Currently, image spam is evaluated to be roughly 50% of all spam traffic and is still on the rise, thus a serious research issue. Filtering mails is one of the popular approaches used to block spam mails. This work proposes new model ReP-ETD (Repetitive Pre-processing technique for Embedded Text Detection) for efficiently and accurately detecting spam in email images. The performance of the proposed ReP-ETD model has been evaluated across the identified parameters and compared with other existing models. The simulation results demonstrate the effectiveness of the proposed model. © 2014 IEEE.

In a passenger vehicle the main object is the seat that has to be not only ergonomically suitable to the commuter, also economically viable to the establishment. It is one of the crucial component to be considered when defining comfort in a moving vehicle. Different levels of comfort in diverse conditions are dictated by combination of static and dynamic factors. This research attempts to study the comfort zone of a bus passenger seat through subjective and objective evaluations at the human-seat interface. To study the subjective evaluation through direct response, an accelerometer to measure vibration on the seat is used while commuting between defined destinations. For the objective evaluation, analytical tests were conducted with dampening materials. The study is in uncontrolled condition that refers to the road trials or field tests carried out in a moving vehicle which produced random vibrations. The results showed that, the road conditions effects besides the postures and size of the passenger. A seat structure proposed with dampener properties; prove to be more effective in realising seat vibration comfort. The comfort values of this proposed seat are higher than the values for the current existing seat arrangement. A lower discomfort means journey with less fatigue. By improving the seat stricture using the said method for the vehicle seats, such as public transport buses, could provide better ride comfort for local purposes.

Two nitro substituted ethyl (2E)-2-cyano-3-phenylprop-2-enoate with molecular formula C12H10N2O4 have been synthesized and characterized by single-crystal X-ray diffraction. These two structures assemble via weak C-H···O=C/O (nitro group), C-H···N, and π-π intermolecular interactions which contribute towards the stability of the crystal packing. The lattice energies have been calculated using the PIXEL approach. Furthermore, high level DFT + Disp calculations for comparison with the pairing energies obtained from PIXEL method have been performed. An analysis of Hirshfeld surfaces and fingerprint plots facilitates a comparison of intermolecular interactions, which are the key elements in building different supramolecular architectures. Graphical Abstract: The manuscript highlights the evaluation of molecular conformation and crystal packing in two nitro derivatives of ethyl (2E)-2-cyano-3-phenylprop-2-enoate. 1. Molecular conformation in the solid state and compared with that in the gas phase. 2. Vibrational frequency calculations using TURBOMOLE. 3. Lattice Energy calculations using PIXEL. 4.
