On BornologicalStructure For multi criteria sequencing problem on one machine, we proposea modified branch and bound algorithm (MBAB) to find efficient(pareto optimal) solutions in this paper. The criteria are total completion time (∑𝐶𝑗), total lateness(∑𝐿𝑗), and maximum tardiness (Tmax). A collection of n independent tasks(jobs) has to be sequenced on one machine , tasks(jobs)j (j=1,2,3,.....,n) requires processing time Pjand due data dj. The MBAB algorithm depends on branch and bound technique. Applied examples are used to show applicabilityof MBAB algorithm. The MBAB algorithm is compared with complete enumeration method (CEM). Conclusions are formulated on the performance of the (MBAB) algorithm

Comparison between MDDV and VADD routing protocols in VANET(Case Study) Routing is the process of delivering a packet from a source to a destination in the network using a routing algorithm that tries to create an efficient path. The path should be created with minimum overhead and bandwidth consumption. In the literature, routing protocols in VANET were categorized in many ways, according to different aspects. In the present study, we prefer the classification based on the number of hops to reach the destination node. The literature, these are single-hop and multi-hops protocols.

Preparation and Optical Characterization of Poly (Vinyl Alcohol): Eosin-Y Films Synthesized bySolventCasting Method It was found that the effect of PVA-doped Eosin-Y on the optical properties of the composite films was intentional as the PVA films were deposited by a solvent casting process with a thickness of 25 ± 1 μm and were grafted with different absorptions of Eosin-Y. The optical diffusivity (%) was described within the wavelength range of (200-900 nm), as well as the effect of the doping ratio on the optical properties of the prepared films. The results showed that layers with indirect developments are acceptablein the interband that are affected by the doping ratio. The band gap of the doped films decreased to (2.20 eV), (2.17 eV), and (2.13 eV)for doping ratios of (2%, 4%, and 6%), respectively, compared to the pure film's 3.89 eV
