The records maintained by Jump Lists have the potential to provide a rich source of evidence about users’ historic activity to the forensic investigator. The structure and artifacts recorded by Jump Lists have been widely discussed in various forensic communities since its debut in Microsoft Windows 7. However, this feature has more capabilities to reveal evidence in Windows 10, due to its modi...

This study aimed to compare the kinematics and kinetics during the landing of hop-jump and step-close-jump movements in order to provide further inferring that the potential risk of ACL injuries. Eleven elite male volleyball players were recruited to perform hop-jump and step-close-jump tasks. Lower extremity kinematics and ground reaction forces during landing in stop-jump tasks were recorded....

Derivatives are alternative financial instruments which extend traders opportunities to achieve some financial goals. They are risk management instruments that are related to a data in the future, and also they react to uncertain prices. Study on pricing futures can provide useful tools to understand the stochastic behavior of prices to manage the risk of price volatility. Thus, this study eval...

This study aimed to determine the role of strength, expulsive power and range of motion of lower limb muscle on the fencing performance of elite florists. In this study, eight elite fencers’ participated. Kinetic variables measured using force plate and kinematic variable measured using motion analysis system. The squat jump test used to measure the compulsive power of the lower extremity muscl...

Background. Several researchers have studied the effects of type of feedback on learning motor skills, but there are few studies on the interaction between personality traits and the type of feedback. Objectives. This study aimed at investigating the effect of type of feedback on intrinsic motivation and learning volleyball jump serve in students with neuroticism. Methods. A total of 59 femal...

Objective: This investigation aimed to compare the effect of neuromuscular, strength and combined training on dynamic balance and sports performance including sprint, agility and power abilities in female basketball players. Method: In this semi-experimental study, 42 female professional basketball players (age 19-25 years) were assigned to three groups (neuromuscular (NM), strength (ST), and ...

INTRODUCTION Phase ratio is a measure of effort distribution in the triple jump, and defined as the ratio of three phase distances of the triple jump. Hop-dominant, balanced, and jump-dominant techniques were three triple jump techniques defined based on phase ratio. Although previous studies demonstrated that individualized optimal phase ratios exist [3], the importance of the phase ratio cann...

The anterior cruciate ligament (ACL) injury is a common occurrence in sports requiring stop-jump tasks. Single- and double-leg stop-jump techniques are frequently executed in sports. The higher risk of ACL injury in single-leg drop landing task compared to a double-leg drop landing task has been identified. However the injury bias between single- and double-leg landing techniques has not been i...

Asset returns have been modeled in continuous time as diffusions by Black and Scholes (1973) and Merton (1973), as pure jump processes by Cox and Ross (1976), and as jump-diffusions by Merton (1976). The jump processes studied by Cox and Ross display finite activity, while some recent research has considered some pure jump processes with infinite activity. Two examples of these infinite-activit...

The purpose of this study was to evaluate the effect of eight weeks strength and plyometric trainings on knee joint position sense. In this study, 45 male students (21.7±2.17years, weight 69.7±7.89 kg, and height 177.2±5.83cm) volunteered and selected as subjects to participate in this semi-empirical study. Subjects divided in three groups include strength (n=15), plyometric (n=15) and cont...
