The placement of artificial reef (AR) units on the seabed modifies velocity field water, making nutrients circulate properly and creating necessary habitat for settlement desired species. This paper proposes a methodology determining circulation in vicinity one specific AR unit module previously defined existing literature. has been based both application three-dimensional hydrodynamic criteria...

The 1978 ITTC Power Prediction method is used to predict the propulsive power of ships through towing tank testing. form factor approach and its determination in this have been questioned. This paper investigates possibility improve predictions by introducing Combined CFD/EFD Method where experimental replaced double body RANS computations applied for open cases KVLCC2 KCS, including first-time...

Towing sleds while walking is a popular resistance exercise for the healthy athlete. One reason for the popularity of sled towing is that it is widely believed to be a ‘functional’ exercise. Preliminary research suggests towing while walking can increases lower extremity moment impulses; however whether towing a sled utilizes the same coordination patterns as un-resisted walking is unknown. Whi...

This paper aims to describe a deterministic generation of extreme waves in a typical towing tank. Such a generation involves an input signal to be provided at the wave maker in such a way that at a certain position in the wave tank, say at a position of a tested object, a large amplitude wave emerges. For the purpose, we consider a model called a spatial-NLS describing the spatial propagation o...

The discharge of ballast water may introduce and transport unwanted marine organisms to the discharging area. Marine Environment Protection Committee (MEPC) IMO consider action as hazard due possibility having negative impact on receiving ecosystems. Many researchers have investigated possible solutions for management minimize risks including free system. concept system is replace conventional ...

Abstract A towing tank is utilized to investigate the flow field around a two-dimensional submerged foil model operating near free surface. Free surface effects are analyzed for steady and unsteady velocity. The model’s submergence depth angle of attack varied. Tests conducted facing upside-up upside-down. deflection recorded experimental results validate an analytic that deployed predict wake ...

Renewable energy resources need to be explored to maintain and meet energy demand and replace the slowly depleting fossil fuels.  Malaysia, surrounded by sea with long coastlines, is poised to exploit the potential of this energy. This research work aims at designing a suitable device to extract energy from Malaysian sea current.  Malaysia’s ocean has a low current velocity averaging 0.56 m/s, ...

[Purpose] This study investigated the reliability of ankle dorsiflexion passive range of motion (DF-PROM) measurements obtained using a goniometer and Biodex dynamometer in stroke patients. [Subjects] Fifteen stroke patients participated in this study. [Methods] Ankle DF-PROM was assessed using a goniometer and Biodex dynamometer. Ankle DF-PROM was measured during two sessions with 7 days betwe...

The purpose of this study was to determine the influence of towing force magnitude on the kinematics of supramaximal sprinting. Ten high school and college-age track and field athletes (6 men, 4 women) ran 60-m maximal sprints under 5 different conditions: Nontowed, Tow A (2.0% body weight [BW]), Tow B (2.8% BW), Tow C (3.8% BW), and Tow D (4.7% BW). Three-dimensional kinematics of a 4-segment ...

Objectives: The purpose of this study was to assess the practical use of heavy sled towing and its acute implications on subsequent sprint acceleration performance. Design and Methods: Eight healthy male varsity team sport athletes (age: 21.8 ± 1.8years, height: 185.5 ± 5.0cm, weight: 88.8 ± 15.7kg, 15m sprint time: 2.66 ± 0.13s) performed sprints under three separate weighted sled towing condi...
