  • Abstract:

    The Internet has turned our world upside down. It has revolutionized all the things we do. It has been transformed from time to time and is now embedded in each and every aspect of our day-to-day life. Most of us are aware of its good cause but no one tends to look for the evil one. As we say the Internet has changed various things, it has changed the traditional way of battles too - Cyber war. A term which is gaining popularity in recent times. Cyber warfare refers to attacks which are deployed virtually in order to disrupt any country's stability; it might result in a drop of economy or even death of innocent lives. The Iranian Nuclear Facility at Natanz faced a cyber-breach which led to a blackout until emergency power systems kicked in. The result was what sounded like a slow-motion explosion as centrifuges crashed into each other. This paper is targeted to examine working and construction of the Stuxnet.whch will include elaboration of various aspects of this targeted malware.

  • Abstract:

    Cerebral palsy (CP) refers to a non-progressive change in the central nervous system, generating motor deficits and functional impairments. The involvement of the upper limb restricts the active participation of children with CP in activities of daily living, causing dependence on the family group. Assessments make up the framework of health professionals to outline treatments and monitor the patient's evolution. With the above, the aim of this bibliographical research was based on finding ways to assess muscle strength in children with CP, resulting in the identification of thirteen publications, whose applications all occurred in children from 5 years of age onwards. Therefore, the development of a device capable of objectively measuring the grip muscle strength in children with CP, from the early years of life, will contribute to the generation of quantitative, accurate information that will assist in the diagnosis and monitoring of treatment with practical application by professionals of health..

  • Abstract:

    Optimal Power Flow (OPF) is one of the major power system planning and operation problem. It is used to minimize the generation cost and power losses while maintaining the power system stability. It is considered as a complex optimization problem which includes linear, non-linear and large-scale constraints. This problem is essential to obtain the objectives while maintaining constraints. Moreover, as wind power growth, the power systems are facing challenges for operating and control to maintain the stability and continuity. This paper focuses on applying the OPF considering wind energy resources. A recent metaheuristic algorithm called ant lion optimizer (ALO) is used to solve the OPF problem. The OPF objective considers parameters such as minimizing the operating cost, minimizing the power losses, minimizing the wind power curtailment and improving the voltage profiles. It is subjected to power system and wind energy constraints. It is implemented by a MATLAB code for optimizing the parameters of the OPF. To evaluate the ALO performance in solving the OPF problem, a modified IEEE 30-bus system includes wind turbine generators is employed..

  • Abstract:

    The screw conveyor is a compact, simple and low-maintenance system that is still used for conveying bulk material in our days. However, this simplicity in its components (screw, pipe and bearing supports) is compensated by its considerable complexity on the movement of the material along the helix in the screw. What causes, an easy reproduction of the equipment without considering some type of engineering analysis for these systems. This will commonly generate mechanical problems as a unexpected fracture in its components, changes in flow rate, shutdowns in production, higher energy consumption when there are oversized power systems, that the original system did not present. For this reason, this article proposes a design methodology to dimension the geometric characteristics of a screw conveyor system based on the necessary production capacity. Likewise, the procedure to be used to perform the mechanical analysis by resistance through the theory of distortion energy, and the strain generated in the pipe and screw components, that allow the system to work safely, is exposed.

  • Abstract:

    The viability of firms that participate in industrial symbiosis (IS) is influenced by the impact that by-product synergies have on the economic efficiency and resilience of those firms in the IS network. Systems theory, industrial ecology, and value chain dynamics constitute the necessary frameworks to analyze the viability of IS value chains through efficiency and resilience assessments. Using Mexico's Altamira Industrial Port as a case study, we identify and describe three IS value chains A, B and C and build variables to measure viability through efficiency and resilience. We find that only the three participating firms in value chain B are both sufficiently efficient and resilient to constitute viability..........

  • Abstract:

    Bottlenecks in any manufacturing unit are the main causes of reduced efficiency and productivity. Bottleneck can be caused by improper method of performing a particular operation, machinery condition and unnecessary non-value-added time. The major cause of bottleneck in a labor-intensive manufacturing unit is the improper method of performing a operation. Operators create a lot of non-value-added time because of stoppages or preparing for a start-up before actually performing the operation. Sewing a particular part is a sort of start-stop process, where the operator has to frequently start and stop the sewing machine. So, every time the sewing is started, the operator takes some time preparing for the operation........

  • Abstract:

    Perishable items such as food products, vegetables, flowers, ready-mixed concrete, blood and etc. are usually destroyed during production and delivery process, so to prevent spoilage of such products, these products must reach the customer at the appropriate time to the manufacturers. One of the effective factors in the timely delivery of various products to the customer is the choice of the optimal delivery route, which is referred to as the issue of vehicle routing. The issue of vehicle routing for the distribution of various products is one of the most widely used issues in the field of operations research, which is very useful in planning the transportation fleet. In this Research, we seek to determine the operational plan of homogeneous vehicles with limited capacity to send products from the central warehouse to a group of customers that are geographically dispersed in different areas, so that the number of vehicles and travel costs are minimized.........
