Visual signatures construction of images is an essential step for the CBIR system. When the database size become larger. Most existing algorithms (e.g. k-means, Kd-tree, Mean-shift) to build signature become unfavorable due to the prohibitive time and space requirements. In this paper we propose the randomize color signature based on the LSH technique. The proposed descriptor benefited of the e...

Designs of hardware and software systems have grown in complexity to meet the demand for improved performance. The complexity of the design often manifests itself in the form of subtle and intricate design flaws and bugs. The cost of these errors can be prohibitive and often dictates the lifetime of a product. Most design teams allocate a substantial amount of their resources in testing and ver...

The solution of the time-dependent Schrödinger equation for systems of interacting electrons is generally a prohibitive task, for which approximate methods are necessary. Popular approaches, such as the time-dependent Hartree-Fock (TDHF) approximation and time-dependent density functional theory (TDDFT), are essentially single-configurational schemes. TDHF is by construction incapable of fully ...

Finding the nearest point on a given 2D or 3D object computation is a problem that arises in many computer graphics applications, such as interactive modeling, rendering of implicit surfaces or collision detection. Unfortunately, for objects with complex geometry such as curves or surfaces, the computation cost becomes prohibitive as a minimization process acting in multiple dimensions has to b...

Bounded-exhaustive exploration of test case candidates is a commonly employed approach for test generation in some contexts. Even when small bounds are used for test generation, executing the obtained tests may become prohibitive, despite the time for test generation not being prohibitive. In this paper, we propose a technique for reducing the size of bounded-exhaustive test suites. This techni...

Transcatheter aortic valve implantation is being established as an alternative treatment for some patients with symptomatic severe aortic stenosis who are not considered suitable for surgical aortic valve replacement because of prohibitive surgical risk.1–3 One of the potential complications is complete atrioventricular block requiring definitive pacemaker implantation. This complication occurs...

Neonatal surgical mortality has steadily fallen over the last five decades. Improved survival does not appear to be related to the introduction of new operative procedures. Most of the basic procedures were developed by 1960. Eight developments appear to be responsible: (1) The growth of pediatric surgery resulted in widespread availability of neonatal surgeons and dissemination of knowledge ab...

The current study aimed to explore cultural and social network influence on HIV vulnerability among Men who have Sex with Men (MSM) population in Yogyakarta, Indonesia. A qualitative inquiry employing in-depth one-on-one interviews was carried out with 24 MSM participants in July 2015. Data were analysed using a framework analysis and guided by the Social Networks Theory (SNT) as a conceptual f...

This study investigated trespassing accidents, trespassing and related countermeasures to provide information for prevention of trespassing accidents on Finnish railways. The study includes five complementary substudies, of which two included accident analyses and three collected information on railway trespassing by means of surveys, interviews and field observations. The main results showed, ...
