Catamaran resistance is very complex compared to monohull resistance, so it is particularly worthy of research. The below-water-level hull form influences the fluid flow characteristics around the ship, which either increases or decreases the total resistance. This study focuses on developing a new hull form by using the Lackenby Method...

The relative significance of
the parallel middle body and stern form in the wake formation of single-screw
large ships and their contribution to the ship?s viscous resistance are studied by using computational fluid dynamics (CFD). A
10450-DWT tanker is considered by varying the ratio of the
parallel-middle-body?s length to the ship?s length (Lmb/L) and...

In this study, modeling of the crossing point temperature (CPT) phenomenon in the low-temperature oxidation of coal was carried out using COMSOL Multiphysics®. Low-temperature oxidation can lead to spontaneous combustion of coal stockpiles. The CPT phenomenon was modeled with the kinetics data obtained from a prior laboratory experimental study. The...

Research and development activities on Liquefied Petroleum Gas (LPG) vehicles have increased LPG engine performance to that of gasoline engines. LPG evaporation in the fuel system also has a potential cooling effect that can be taken advantage of. The results from previous studies, however, do not explain the level of...

The
pavement of the nailed-slab system has been proposed as an
alternative solution for addressing the rigid pavement problem in soft soils.
This system is used for developing a rigid pavement. The simple method of using an equivalent modulus of subgrade reaction (k?) in nailed-slab system analysis was
proposed by a previous researcher. This...

We conducted a finite element simulation by using a computer program, ATENA, to verify
the behavior of T-section reinforced concrete beams strengthened by bonded wire
ropes in the negative moment region with a pretensioned initial prestressing force; we compared this
behavior with that in experimental tests. The simulation was performed on five models...

The findings of numerous
studies on the responses of stream quality indicators
to different levels of watershed development have been integrated into an impervious cover model. The focus on one development stressor, namely the
impervious cover, allows the decision makers to use the impervious cover model as a watershed planning tool
to forecast stream...

Bus arrival time is very
important to passengers, not only at the origin terminal but also at every
stop. If there is no predicted arrival time at a stop, the headway designed
should match the bus frequency at the stop. The uncertainty in bus arrival time
can hinder the headway from matching the bus...

FinFET (Fin Field-Effect
Transistor) technology has recently seen a major increase in adoption
for use in integrated circuits because of its high immunity to short channel
effects and its further ability to scale
down. Previously, a major research contribution was made to reduce the leakage current in the
conventional bulk devices. So many different alternatives...

One main problem that must be coped with by a
telecommunication company (Telco) is the connection interference experienced by
customers. When a cell phone number Pn in a region R suffers from
a connection problem, the first step commonly taken by that Telco?s technician
is to find the base transceiver station (BTS) among existing...
