As the demand for nature-based coastal protection methods increases globally, there remains a stringent need to develop evidence-based design guidance many of these and techniques. Anchored Large Woody Debris (LWD) has been used as an economical method several decades has, more recently, gained notoriety approach. Existing guidance, however, is both limited not significantly rooted in academic ...

Abstract Many different factors can influence the outcomes of light-weight deflectometer (LWD) tests. Some these are specific to type used LWD, while others related testing conditions. This paper summarizes findings a detailed investigation into relationships between variables altering measurements test. Field was performed investigate effect sensing configuration (measurement plate vs ground s...

Single-well acoustic imaging in logging-while-drilling (LWD) has important application potential evaluating cluster-well drilling safety as it can be applied to the real-time detection of an existing cased borehole from a new well during drilling. Forward modelling help us understand mechanism elastic-wave radiation, scattering and reception. In this work, we investigate characteristics wavefie...

a r t i c l e i n f o a b s t r a c t A logging-while-drilling (LWD) system is usually deployed in the oil drilling process in order to provide real-time monitoring of the position and orientation of a hole. Encoded signals including the data coming from down-hole sensors are inevitably contaminated during their collection and transmission to the surface. Before decoding the signals into differ...

The influence of Large Woody Debris (LWD) and tributary confluences on the grain size distributions of a mountainous stream network in the Western Cascades was analyzed. Longitudinal Trends in grain sizes were determined to be increasing with downstream distance. The influences that LWD and tributary confluences have on these trends were investigated using spatial and bivariate correlations. Th...

In this paper, we describe the development of a Greedy Random Adaptive Search Procedure (GRASP) where two low-level graph heuristics, Saturation Degree (SD) and Largest Weighted Degree (LWD) are dynamically hybridised in the construction phase to construct solutions for exam timetabling problems. The problem is initially solved using an intelligent adaptive LWD and SD graph hyper-heuristic whic...

A logging-while-drilling (LWD) caliper is a tool used for the real-time measurement of a borehole diameter in oil drilling engineering. This study introduces the mechanical structure and working principle of a new LWD caliper based on ultrasonic distance measurement (UDM). The detection range is a major performance index of a UDM system. This index is determined by the blind zone length and rem...

LWD is associated to SHOX haploinsufficiency, in most cases, due to gene deletion. Generally FISH and microsatellite analysis are used to identify SHOX deletion. MLPA is a new method of detecting gene copy variation, allowing simultaneous analysis of several regions. Here we describe the presence of a SHOX intragenic deletion in a family with LWD, analyzed through different methodologies. Genom...
