The research objective is to find better solutions to solve problem of bottom-neck in production line of light-soaked Divider Mechanic of case study company producing promotional labels, price tag, floor sticker, Stand-up signage for indoor and outdoor use with a comprehensive printing style using system simulation with Arena software. The results were as follows. In case of production of 25 pieces/day, the best way to improve system efficiency is Scenario 4, reducing the completion time of the system of down to 23.12%, and Scenario 3, reducing the system time of down to 22.91% consecutively. In case of production of 50 pieces/day, the best way to improve system efficiency is Scenario 3, reducing the system completion time of down to 23.39% and then Scenario 4, reducing the completion time of the system of down to 22.57% consecutively. In case of production of 100 pieces/day, the best way to improve system efficiency is Scenario 3, reducing the system completion time of down to 24.03%. and then Scenario 4, reducing the completion time of the system of down to 23.03% consecutively.

Graphene-enabled nano antennas constitute a novel paradigm which is a current trend of research among designers. Graphene-based nano-antennas with nanometer in size have shown to radiate electromagnetic waves at the terahertz (THz) frequency band. Proposed research activity is an attempt of Terahertz Nano dipole antenna design through the Finite Difference Time Domain (FDTD) based numerical simulation software, i.e. CST. Graphene material as adipole antenna has been explored to get a radiation performance. Before hand absorption, reflection and transmission characteristics of the grapheme layer has been explored. Designed antenna is analyzed in terms of the reflection coefficient, and radiation pattern etc. An attempt has been done for resonance study of graphene based nano dipole antennas, in that patch antenna length parameteris changed and performance is observed. The impact of most crucial parameter, i.e., chemical potential on the grapheme radiation performance has been analyzed in terms of reflection coefficient. Proposed antenna may be suitable for wireless nano communication applications. Keywords: Terahertz antennas, computer simulation technology, microstrip dipole antenna, reflection coefficient, radiation pattern

The level of cyber-attacks that violate the devices and web platforms are tools of risk and damage that focus on subtracting private and restricted information of users without administrative permissions, that is why the proposal in this research is to raise cyber-attacks where operations are performed on a massive scale and through fraudulent techniques and strategies, under the tools of: (a) Nmap, (b) SQL Injection, (c) Fiddler, (d) Burp Suite performing a comparison study of these tools in order to be able to demonstrate how they are effective against web platforms and how the web administrator or technician should take the necessary care against these cyber-attacks. In summary, the Nmap and Injection SQL tools are contemplated to have free access for its variety of operating systems under the tool platform allowing to analyze the security of the system for sending packets to different devices. In addition, the Fiddler and Burp Suite tools have a paid license access due to the differences in their product costs. Finally, as a recommendation we can say that the study can be improved by implementing more selection criteria and adding more tools to expand the topic with classifications by type of structure. Keywords: Cyber-attacks, Nmap, SQL Injection, Fiddler, Burp Suite.

T-shaped composite cleat are used in thin walled structures including aircraft fuselage with wings, with the skin carrying membrane loads and the stiffeners carrying bending loads and resisting skin buckling. The project includes T-shaped stiffened Aluminum cleat will be used for analysis purpose along with Carbon fiber composite reinforcement T-stiffened composite cleat. The carbon fiber reinforced T-stiffened panels were manufactured with carbon fiber arranged in a [45/0/45/0/45] s ply pattern. The model of T-stiffened composite reinforces panels and T -stiffened Aluminum panel is made in Catia V5R20. Static structural of specimen will be perform using ACP tool in ANSYS 19 software. In experimentation, tensile test of both specimens have been performed on UTM. The comparative analysis was carried out between the Analytical and experimental results. After manufacturing, the comparative analysis result and conclusion was drawn. Keywords: ANSYS, CATIA, COMPOSITE, UTM.

Now a day’s increases in vehicle demand at a lower rate are necessity of vehicle manufacture. Expectation in terms of durability, efficiency and cost is raising exponentially by customers. Over designed components in vehicle leads to increase weight and reduced efficiency. Pitman arm used to steer vehicle can be redesigned and modified for achieving less weight and thus cost. Existing pitman arm component available in market will be reverse engineered and CAD modeled using CATIAV5software.Finiteelement Discretization & Analysis will be carried out using Ansys package. FEA will help in finding out high strain locations in component and also defining area which can be modified. Strain gauging will be done on areas of high strain location indicated by FEA software. Fixture will be designed for mounting component on UTM. Machining will be done to remove excess material from component. Comparative analysis will be done between experimental and FEA results. Conclusion and future scope will be suggested. Keywords: Pitman Arm, Optimization, CATIA, FEA
