This study analyzed and enhanced the modified Blowfish algorithm (MBA) encryption. The modification retained original structure, process use of two S-boxes in MBA but presented derivation processes f-function which was originally placed to prevent symmetry. case’s performance using avalanche effect time efficiency. After comparing first second MBA, further improved by 5.47%, thus improving secu...

The unmanned aerial vehicle (UAV) path planning problem is primarily concerned with avoiding collision obstacles while determining the best flight to target position. This paper first establishes a cost function transform UAV route issue into an optimization that meets UAV’s feasible requirements and safety constraints. Then, this introduces modified Mayfly Algorithm (modMA), which employs expo...

Being abundant and non-polluted, solar energy is an increasingly desirable source. Growing research concerned about maximum acquisition from panels, especially in the automatic sun-tracking of panels. This paper presents a modified algorithm based on “PSA Algorithm” proposed 2001. And new tracking system with two-axis designed algorithm. The PSA used to calculate sun’s hori...

This paper analyzes the Modified Cellular Message Encryption Algorithm (M-CMEA) which is an enhanced version of the Telecommunication Industry Association’s Cellular Message Encryption Algorithm. We analyzed more properties to, “Why is CMEA weak?” and modification required to secure the CMEA.

We develop a modified willow tree algorithm for option pricing. Our numerical results show that it approximates the true prices more quickly and precisely than the binomial tree, especially in d-factor models for d = 2, 3, 4, 5. A bound on the theoretical rate of convergence of the modified willow tree algorithm is established.

Roads play a vital role to the people live in different places and, from day to day, they travel to schools, to work, to shops, and to transport their goods. Even in this modern world, roads remain one of the mediums used most frequently for travel and transportation. The computation of a shortest path between different locations appears to be a key problem in the road networks. The wide range ...
