This study focuses on analyzing the cooperation between Turkey and Pakistan and evaluating the general circumstances in the defense sector. Pakistan and Turkey are considered two key military and geopolitical powers of the world. The relations between Pakistan and Turkey do not rely on regular politics, but since the first World War, the people of the two countries have had a sincere and strong relationship based on their mutual love and friendship. In the last 20 years especially, Turkey and Pakistan have played an important role in Asia in counterterrorism, regional security issues, and long-term defense strategies and have formed strong cooperation. This study, thus, aims to examine and evaluate joint defense industry cooperation between Pakistan and Turkey in terms of their core security and strategic interests, especially in the context of rapidly developing and unstable international relations after the September 11 attacks in 2001. The study utilizes the systematic literature review method to achieve its aim. The findings show that Turkey and Pakistan have strengthened ties in the last 20 years, but there is still more room for potential cooperation.

Heavy-vehicle Anti-lock Braking System (ABS) controllers are commonly tested using simulations before vehicle testing, but pneumatic actuation and measurement limitations can affect the results in the field. This paper presents the complete design process of a pneumatic ABS controller. System identification tests, estimation experiments, and reverse engineering methods were used to develop the models used for testing, including a vehicle model, pneumatic circuit model, etc. Model-in-the-loop (MIL) and software-in-the-loop (SIL) simulations were used to test and validate the algorithm in the simulation environment. Hardware-in-the-loop (HIL) simulations were also used to test and tune the ABS algorithm using a physical pneumatic circuit before real vehicle testing. Lastly, the ABS controller was deployed to a custom ECU and tested on the real vehicle on dry and wet asphalt. The developed controller prevented sustained wheel lock and produced repeatable deceleration and stopping-distance results during dry- and wet-asphalt testing. Qualitative assessment by the test driver and engineering team also indicated ABS intervention and modulation characteristics broadly consistent with commercial alternatives.
