The sea wave causes excess resistance which is out of scope of calm water resistance. The total wave force in horizontal plane is divided into “Added Resistance” and “Drift Force”. In this study, based on Gerritsma and Beuckelman[3] hypothesis a computer program has been developed for calculation of added resistance and drift force at various ship speeds and various head...

To study the water entry ballistic trajectory of a torpedo, the wind tunnel experiment has been done based on the similarity principle. Then the drag coefficient of the torpedo is got when it enters the water, which is amended by the introduction of continuous supercavitation factor and local cavity effect factor. The vertical plane motion equations are established to get the torpedo’s trajecto...

• Overview of the smile problem • Local volatility models: mixture of densities' model • A practical choice: an uncertain volatility model • The link: a projection result • Properties, precautions, niceties; explanatory power • Mixtures of densities in the multivariate context: – brute force approach (Simply Correlated Mixture Dynamics) – subtler approach: MultiVariate Mixture Dynamics – consis...

In order to provide theoretical support for the use of unmanned equipment by marine police force, this paper takes current situation drones in Asia-Pacific countries as entry point, type characteristics is introduced and different materials typical task scenarios force drones, needs maritime analyzed composed, a variety operational methods are emphasized.

The Council on Accreditation of Nurse Anesthesia Educational Programs appointed a Standards Revision Task Force to develop new accreditation standards. After 3 years of research and development (2011-2013) by the task force, the Council approved the first entry-level Practice Doctorate Standards and the first voluntary Post-graduate CRNA Fellowship Standards in January 2014. This defining momen...

Inappropriate machining conditions such as cutting forces cause tool failures, poor surface quality and worst of all machine breakdowns. This may be avoided by using optimal machining parameters, e.g. feed-rate, and continuing to monitor it throughout the machining process. To optimize feed-rate, we propose a system that consists of an optimisation module, a process control module and a knowled...

As a part of an analysis of the nature of chilling injury to seeds, measurements were made of the initial linear rates of water entry into and solute leakage out of cotyledons of soybean at various temperatures. Arrhenius plots were approximately linear for water entry into both living and dead cotyledons, with the slope (and activation energy) for entry into living cells being insignificantly ...
