the ground improvement using plastic board drain (pbd) in soft soil was undertaken by sand mat formation, pbd installation, preloading surcharge, and removal of surcharge. during this procedure, the sand mat formation induced an initial settlement. however, it was very difficult to estimate that settlement due to pbd installation, which frequently destroyed the instruments installed in the grou...

We present a phenomenological dynamical model describing the force induced melting as responsible for the DNA overstretching transition. The denaturation mechanism is developed under the framework of the mesoscopic one-dimensional Peyrard-Bishop-Dauxois (PBD) picture which models the melting features of a polymer chain by means of a Morse potential and the stacking interaction. We find a good a...

Since it is important for service robots to be easily programmed, an interactive programming techniques like Programming by Demonstration (PbD) are obviously adequate programming methods. Image processing systems play an important role in PbD systems for acquiering the demonstration steps of the user. However, today's image processing systems are hardly capable of extracting relevant informatio...

We present three descriptors of texture feature of a region. Namely, the homogeneous texture descriptor (HTD), the edge histogram descriptor (EHD), and the perceptual browsing descriptor (PBD). They are currently included in the Committee Draft of the MPEG-7 Visual (ISO/IEC 15938-3). Each descriptor has a unique functionality and application domain. HTD and EHD describe statistical distribution...

OSINT stands for Open Source Intelligence, (O)SI for (Open) Social Intelligence, PbD for Privacy by Design. The CAPER project has built an OSINT solution oriented to the prevention of organized crime. How to balance freedom and security? This position paper describes a way to embed the legal and ethical issues raised by the General Data Reform Package (GDRP) in Europe into this kind of surveill...

In this paper, we investigate the PBD-closure of sets K with {7, 13} ⊆ K ⊆ {7, 13, 19, 25, 31, 37, 43}. In particular, we show that v ≡ 1 mod 6, v ≥ 98689 implies v ∈ B({7, 13}). As a preliminary result, many new 13-GDDs of type 13q and resolvable BIBD with block size 6 or 12 are also constructed. Furthermore, we show some elements to be not essential in a Wilson bases for the PBD-closed set {v...

Programming by demonstration (PBD) utilizes a human teacher to train a computer system to perform tasks within that system. This technique effectively improves productivity for many tasks, in many domains. Many tasks are repetitive in nature; these can be learned by PBD by recognizing the repetitions and generalizing these to iterative programs. We present a domain-independent approach to itera...

The development of high-tech industries stimulates the growth requirements to metal structures and a complex their main special properties. use pulsed electrical discharges, plasma currents, electromagnetic fields, combined effects improve mechanical characteristics metals alloys is relevant in connec-tion with need replacing traditional energy-intensive technologies structural materials more a...

background although heller myotomy is one of the most effective treatments for achalasia, it may be associated with early or late symptom relapse in some patients. therefore, additional treatment is required to achieve better control of symptoms. aim : to evaluate the safety and efficacy of pneumatic balloon dilation (pbd) in patients with symptom relapse after heller myotomy. methods thirty si...
