‘e rapid adoption of smartphones with di‚erent types of advanced sensors has led to an increasing trend in the usage of mobile crowdsensing applications, e.g., to create hyperlocal weather maps. However, the high energy consumption of crowdsensing, chieƒy due to expensive network communication, has been found to be detrimental to the wide-spread adoption. We propose a framework, called Sense-Ai...

A database management system (DBMS) performs query optimization based on statistical information about data in the underlying database. Out-of-date statistics may lead to inefficient query processing in the system. The existing utility method, which collects statistics in batch mode, suffers from drawbacks such as heavy administrative burden, high system load and tardy updates. In this paper, w...

To help with care work and rescue operations, it is necessary for humanoid robots to have the ability to transport humans steadily and gently. In this research we consider “piggyback” motions for transporting humans. Most people can perform this motion, allowing us to measure and analyze piggyback motions of human subjects using tactile sensing and whole body movements to design whole body cont...

Inherent ignorance of and uncertainties about the future may translate into doubts about the overall viability of market mechanisms. However, these doubts are quelled by a broad empirical observation: market economies thrive. Hayek sometimes abstracted from such ignorance and uncertainties in order to identify the market mechanisms that are essential to thriving economies. His often-overlooked ...

Refractive errors are frequently found following cataract surgery and refractive lens exchange. Accurate biometric analysis, selection and calculation of the adequate intraocular lens (IOL) and modern techniques for cataract surgery all contribute to achieving the goal of cataract surgery as a refractive procedure with no refractive error. However, in spite of all these advances, residual refra...

We present a piggyback server invalidation (PSI) mechanism for maintaining stronger cache coherency in Web proxy caches while reducing overall costs. The basic idea is for servers to piggyback on a reply to a proxy client, the list of resources that have changed since the last access by the client. The proxy client invalidates cached entries on the list and can extend the lifetime of entries no...

Liver transplantation with preservation of the recipient vena cava (piggyback technique) has been performed as an alternative to the conventional method. Outflow disturbance or obstruction of the vena cava in the early period after liver transplantation is associated with high morbidity and mortality. We used side-to-side cavo-caval anastomosis (modified piggyback technique) in a deceased-donor...

We present a review of keratorefractive and intraocular approaches to managing residual astigmatic and spherical refractive error after cataract surgery, including laser in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), arcuate keratotomy, intraocular lens (IOL) exchange, piggyback IOLs, and light-adjustable IOLs. Currently available literature suggests that laser vision correc...

Researches on feeding with Biolekks premix and bentonite clay to pigs for fattening were conducted. It was established that the tested additives have beneficial effect on animals. However the greatest effect was obtained with combined feeding. So the live weight of pigs increased by 5.2% (at P≤0.999), surviving – by 4%, the level of profitability of pork production – by 18.6%, also revealed was...
